PART I

Item 1. | Business.

Introduction

Electro-Sensors, Inc. (“we,” “us,” “our,” the “Company” or “ESI”) manufactures and sells industrial production monitoring and process control systems.

In addition, we may periodically make strategic investments in other businesses and companies, including investments that we believe would facilitate the development of technology complementary to our existing products or investments that we believe present good opportunities for the Company and its shareholders. Our primary focus is to remain an operating company and we do not intend to become an investment company.

ESI was incorporated in Minnesota in July 1968. Our executive offices are located at 6111 Blue Circle Drive, Minnetonka, Minnesota, 55343-9108. Our telephone number is (952) 930-0100.

Products

We manufacture and sell a variety of monitoring systems that measure actual machine production and operation rates, as well as systems that regulate the speed of related machines in production processes.

Our goal is to develop meaningful annual updates to our standard products.

We have a sales agreement with Motrona GmbH, a German control and interface devices manufacturer, under which we have the right to distribute Motrona products in the United States. These products interface with our products on various applications for motion monitoring.

Speed Monitoring Systems

Our speed monitoring systems compare revolutions per minute or speed against acceptable rates as determined by our customers. These systems vary in complexity, from simple systems that detect slow-downs or stoppages, to more sophisticated systems that warn of deviations from precise tolerances and that permit various subsidiary operations to be determined through monitoring the shaft speed.

Our speed monitoring systems also include a line of products that measure production counts or rates, such as parts, gallons per minute, or board feet. These speed monitoring systems also include alarm systems, tachometers, and other devices that translate impulses from the sensors into alarm signals, computer inputs, or digital displays that are usable by the customer.

We have several products used in drive control systems that regulate the speed of motors on related machines in a production sequence to ensure that the performances of various operations are coordinated. The products consist of a line of digital control products for motors that require a complete closed loop PID (Proportional Integral Derivative) control. The closed loop controllers coordinate production speed among process motors and reduce waste.

Temperature Application Products

Our main temperature applications include bearing, gear box, and motor temperature monitoring. The sensors alert an operator when the temperature exceeds or is less than a specified temperature.

Position Application Products

We also offer production monitoring devices that include a belt alignment and slide gate position monitor. The belt alignment monitor is used to determine if a belt is tracking correctly. The slide gate position monitor is used in plant operations to provide feedback of the position of a slide gate. It is also used to provide feedback of the position of a valve or control arm.

Vibration Monitoring Prod u cts

A vibration monitor alerts an operator when the vibration of a machine in a production system exceeds or is less than a specified level.

Tilt Switches

A tilt switch is designed to alert the operator when a storage bin or production system reaches a certain capacity.

Hazard Monitoring Systems

Electro-Sentry We offer the Electro-Sentry 1 and Electro-Sentry 16 hazard monitoring systems, which integrate our sensors for monitoring temperature, belt misalignment, and shaft speed with programmable control logic and LED display interface to create a complete system for hazard monitoring. The systems enable our customers to locate which part of their material handling system is operating incorrectly, typically in less than ten seconds, by using visual indication on the LED displays.

HazardPROTM We market our wireless hazard technology monitoring system under the HazardPRO product name. This integrated hazard monitoring system captures and displays key information in an intuitive format allowing the user to quickly and comprehensively understand the status and history of its processes. The simple but powerful interface gives the user insight into its operations as it strives to maximize safety and facility runtime, while minimizing costs associated with unscheduled maintenance and unplanned downtime. We offer Class II Div I intrinsically safe nodes and sensors that are certified for use in hazardous environments.

During 2017, we updated the HazardPRO software to include a large site system manager link. The link is used to efficiently collect data from sensors placed across a widely dispersed area and has been deployed in sites covering greater than 50 acres. We also added a complete antenna pair mounting system for easy and accurate customer installation.

We expect to continue to expend resources to develop new products and to market new and existing products for use in a wide variety of monitoring applications.

Our corporate web site provides significant information and product application knowledge to existing and prospective customers and our sales partners. Information on our website is not incorporated by reference herein and is not a part of this Form 10-K.

Marketing and Distribution

We sell our products primarily through both our internal sales team and a number of manufacturer’s representatives and distributors located throughout the United States, Canada, Mexico, Bolivia, Chile, Colombia, Guatemala, Peru, United Kingdom, Ukraine, Egypt, Saudi Arabia, India, Indonesia, Australia, New Zealand, China, Taiwan, Korea, Vietnam, Malaysia, Philippines, and Singapore. Sales to customers outside the United States represent approximately 10% of our 2017 sales. We sell our products under the Electro-Sensors, Inc. brand as a range of products from simple sensors to complex integrated monitoring systems. Our customers are businesses in a wide variety of industries, including grain/feed/milling, bulk materials, manufacturing, food products, ethanol, power generation, and other processing industries.

We continue to explore new industries to expand sales and may also consider acquiring compatible businesses or product lines as part of our growth strategy. In addition, we may make investments that we believe present good opportunities for the Company and its shareholders.

We believe that a wide variety of organizations could achieve significant savings in both time and materials by adding production monitoring and drive control technology to existing processes to coordinate the operation of related machines. We sell our products into both the “retro-fit” market and into new manufacturing or processing systems.

We advertise in national industrial periodicals that cover a range of industrial products and attend several local, national and international tradeshows designated for the industry throughout the year. We also use our corporate website and other related industry websites for advertising and marketing purposes.

5

Competition

We face substantial competition in the sale of our production monitoring systems from a broad range of industrial and commercial businesses. Many of these competitors are well established and have greater sales volume. Among our larger competitors are Danaher Controls, Red Lion Controls, 4B Elevator Components Ltd., and Durant Corporation. We believe our competitive advantages include our products superior design and quality, the fact that we sell our products as ready-to-install units, and that our products can be used in a wide range of applications. Our major disadvantages include the fact that our major competitors are much larger, have a broader variety of sensing instruments, and have larger sales forces and established names.

Suppliers

We purchase parts and materials for our systems from various manufacturers and distributors. In some instances, these materials are manufactured in accordance with our proprietary designs. Multiple sources of these parts and materials are generally available, and we do not depend on any single source for these supplies and materials. We have not experienced any significant problem of short supply or delays from our suppliers.

Customers

We do not depend upon a single or a few customers for a material (10% or more) portion of our sales.

Patents, Trademarks and Licenses

The Company relies on a combination of patent, trademark, and trade secret laws to establish proprietary right in its products.

We have registered the name “Electro-Sensors” as a trademark with the U.S. Patent and Trademark Office (“USPTO”), Reg. No. 1,142,310. We believe this trademark has been and will continue to be useful in developing and protecting market recognition for our products. We established the HazardPRO trademark in the first quarter of 2014 and intend to register this trademark.

We hold six patents relating to our production monitoring systems. We believe strongly in protecting our intellectual property and have a long history of obtaining patents, when available, in connection with our research and product development programs. We also rely upon trade secrets and proprietary know-how.

We seek to protect our trade secrets and proprietary intellectual property, including know-how, in part, through confidentiality agreements with employees, consultants, and other parties. We cannot ensure, however, that these agreements will not be breached, that we would have adequate remedies for any breach, or that our trade secrets will not otherwise become known or independently developed by competitors.

Business Development Activities

We continue to seek growth opportunities, both internally through our existing portfolio of products, technologies and markets, as well as externally through technology partnerships or related-product acquisitions. In addition, we may make investments that we believe present good opportunities for the Company and its shareholders.

Governmental Approvals

Although, we are not required to obtain governmental approval of our products, we choose to obtain certain third party certifications to meet our customers’ needs. These certifications may expand our market opportunities in certain industries.

Effect of Governmental Regulations

We do not believe that any existing or proposed governmental regulations will have a material effect on our business.

Research and Development (dollars in thousands)

We invest in research and development programs to develop new products in related markets and to integrate state-of-the-art technology into our existing products. We incurred research and development expenses of approximately $812 and $767 during 2017 and 2016, respectively. We undertake development projects based upon the identified specific needs of the markets we serve.

Our future success depends in part upon our ability to develop new products in our varying segments. Difficulties or delays in our ability to develop, produce, test and market new products could have a material adverse effect on future sales growth.

6

Compliance with Environmental Laws

Compliance with federal, state and local environmental laws has only a nominal effect on current or anticipated capital expenditures and has had no material effect on earnings or on our competitive position.

Employees

As of March 19, 2018, we had 36 employees, all of whom are full-time. We believe that our relations with our employees are good. None of our employees are members of unions.

Our ability to maintain a competitive position and to continue to develop and market new products depends, in part, on our ability to retain key employees and qualified personnel. If we are unable to retain our key employees, or recruit and train others, our product development, marketing and sales could be negatively impacted.

Fluctuations in Operating Results.

We have experienced fluctuations in our past operating results, and expect to experience fluctuations in the future, which may affect the market price of our common stock. Sales can fluctuate as a result of a variety of factors, many of which are beyond our control. These factors include: product competition and acceptance, timing of customer orders, cancellation of orders, the mix of products sold, downturns in the markets we serve and economic disruptions. Because fluctuations may occur, we caution investors that results of our operations for recent periods may not accurately predict how we will perform in the future. We cannot ensure that we will achieve revenue or earnings growth.

Expending Funds for Changes in Industry Standards, Customer Preferences or Technology.

Our business depends on periodically introducing new and enhanced products and solutions for customer needs. Our product development efforts require us to commit financial resources, personnel and time, usually in advance of significant market demand for these products. In order to compete, we must anticipate both future demand and the technology available to meet that demand. We cannot ensure that our research and development efforts will lead to new products or product innovations that can be made available to or will be accepted by the market.

The following paragraphs discuss the Company’s performance for years ended December 31, 2017 and 2016.

Comparison of 2017 vs. 2016 (dollars in thousands)

Net Sales

Net sales increased $666, or 9.3%, to $7,840 in 2017 from $7,174 in 2016. The Company saw an uptick in business in the second half of the year related to our grain, feed, and milling markets compared to the same period in 2016. The 2017 annual increase was driven primarily by an increase in strategic system orders in both our legacy and HazardPRO product lines. Furthermore, our 2017 international business grew by 20.4% as compared to 2016, primarily driven by increased sales to customers in Canada.

10

Gross Profit

Gross profit for 2017 increased $415, or 10.7%, to $4,299 from $3,884 in 2016. Our gross profit margin for 2017 was 54.8% compared to 54.1% in 2016. The slight increase in the gross margin was primarily due to product mix.

Operating Expenses

Total operating expenses increased $175, or 4.7%, to $3,889 in 2017 from $3,714 in 2016, but decreased as a percentage of sales to 49.6% from 51.8%.

| ● | Selling and marketing expenses decreased $107, or 6.8%, to $1,469 in 2017 from $1,576 in 2016, and decreased as a percentage of sales to 18.7% from 22.0%. The decrease resulted primarily from lower aggregate commissions paid to outside sales representatives due to the use of fewer representatives in 2017, and lower travel expenses; partially offset by an increase in compensation to employees.

| ● | General and administrative expenses increased $237, or 17.3%, to $1,608 in 2017 from $1,371 in 2016, and increased as a percentage of sales to 20.5% from 19.1%. The increase was primarily due to a reversal of the HazardPRO contingent earn-out liability of only $45 in 2017 compared to $260 in 2016.

| ● | Research and development expenses increased $45, or 5.9%, to $812 in 2017 compared to $767 in 2016, and decreased as a percentage of sales to 10.4% from 10.7%. The increase, in dollars, was the result of contract engineering fees related to product enhancements and an increase in new product prototypes. The increase was partially offset by a decrease in in lab testing and certification expenses for our HazardPRO product line.

Operating Income

Operating income increased $240, or 141.2%, to $410 in 2017 from $170 in 2016, and increased as a percentage of sales to 5.2% from 2.3%, due primarily to increased revenues, which was slightly offset by increased operating expenses discussed above.

Non-Operating Income

Non-operating income increased $14 to $48 in 2017 from $34 in 2016, primarily as a result of increased interest income due to higher interest rates on Treasury Bills.

Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders’ equity.

Realized gains and losses, including losses from declines in value of specific securities determined by management to be other-than-temporary, are included in the statement of comprehensive income. Realized gains and losses are determined on the basis of the specific securities sold.

Income Taxes

Income taxes were $163, or 2.1%, of 2017 income before income taxes compared to $2, or 0%, of 2016 income before income taxes. The increase was due primarily to increased profitability and a decrease in our deferred tax asset due a decrease in the corporate federal tax rate from 35% to 21%. In December 2017, the Tax Jobs and Cuts Act of 2017 was enacted decreasing the highest corporate federal tax rate to 21%. Detailed information on our income taxes are described in Note 10 to our 2017 financial statements.

Net Income After Tax

We reported net income of $295 in 2017 as compared to net income of $202 in 2016, an increase of $93, or 46.0%. Basic and diluted earnings per share were $0.09 in 2017, compared to basic and diluted earnings per share of $0.06 in 2016.

11

OFF-BALANCE SHEET ARRANGEMENTS

We are not a party to any off-balance sheet transactions, arrangements or obligations that have, or are reasonably likely to have, a material effect on our financial condition, changes in the financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $963 and $840 at December 31, 2017 and 2016, respectively. The increase was mainly due to net cash generated from operating activities, as described below. Working capital was $10,651 at December 31, 2017 compared to $10,249 at December 31, 2016.

Cash generated from operating activities in 2017 and 2016 was $468 and $196, respectively, resulting in a $272 increase in cash from operating activities. The increase was primarily due to an increase in net income and accrued expenses, partially offset by a decrease in accounts payable. The 2017 increase in net income is due to higher sales. The increase in accrued expenses is due to increased payroll related expenses. The 2017 decrease in accounts payable is due to the timing of purchases and payments.

Cash used in investing activities in 2017 was $345, compared to $465 of cash generated from 2016 investing activities. During 2017, the Company had net purchases of Treasury Bills with a maturity date of more than three months of $231 compared to the 2016 net proceeds of $473. In addition, we purchased $114 and $8 of property and equipment during fiscal 2017 and 2016, respectively.

There was no cash used or provided by financing activities during 2017. Cash used in financing activities was $390 during 2016 to make the final payment on the long-term debt owed to Harvest Engineering, Inc. for the technology purchased in February 2014.

Our ongoing cash usage requirements will be primarily used for capital expenditures, potential acquisitions, investments we believe present good opportunities for the Company and its shareholders, research and development, and working capital. Management believes that cash on hand and any cash provided by operations will be sufficient to meet our cash requirements through at least the next 12 months.

12

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. Those decisions include the selection of applicable accounting principles and the use of judgment in their application, the results of which impact reported amounts and disclosures. Changes in economic conditions or other business circumstances may affect the outcomes of management’s estimates and assumptions.

Significant estimates, including the underlying assumptions, consist of the 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.

Economic lives of long-lived assets

We estimate the economic useful life of long-lived assets used in the business. Expected asset lives may be shortened or an impairment may be recorded based on a change in the expected use of the asset. If the expected life of an asset is shortened or an impairment recorded, it could result in an additional charge to depreciation expense.

Realizability of trade receivables

We estimate our allowance for doubtful accounts based on prior history and the aging of our trade receivables. We are unable to predict which, if any, of our customers will be unable to pay their open invoices at a future date. If an account becomes uncollectible and we are required to write off the balance, we would recognize the amount of the additional expense within general and administrative expenses.

Valuation of deferred tax assets/liabilities

We estimate our deferred tax assets and liabilities based on current tax laws and rates. The tax laws and rates could change in the future to either disallow the deductions or increase/decrease the tax rates. We recognized changes in deferred tax assets and liabilities in the period in which the tax law changes become effective. Any change in our deferred tax assets or liabilities could have a material negative or positive effect on our income tax expense.

Valuation of inventory

We purchase inventory based on estimated demand of products. It is possible that the inventory we have purchased will not be used in the products that our customers need or will not meet future technological requirements. If we are unable to use the inventory in our products and it does not meet future technological requirements, we would be required to remove the items from inventory and expense the amount in cost of goods sold.

Valuation of investments

Our investments in available-for-sale securities are valued at market prices in an open market. The prices are subject to the normal fluctuations that could be either negative or positive. Changes in value of our investments do not affect our profitability until the available-for-sale security is sold. At the time of sale, we would recognize a gain or loss on the sale in net income.

Valuation of stock-based compensation expense

We estimate the expected life and forfeiture rates of stock options granted when calculating the value of options using the Black-Sholes-Merton model. The actual life and forfeiture rate could differ from what we estimated. Changes in the life or forfeiture rate of stock options could have a negative or positive impact on our stock-based compensation.

Valuation of the contingent earn-out

We estimated the probability of meeting the revenue targets over the measurement period to determine the fair value of the contingent liability. The actual payout could be more or less than what we have estimated. If the payout or projected payout is more than the recorded value, we would recognize an additional charge to general and administrative expense. If the payout or projected payout is less than the recorded value, we would recognize a decrease in expense to general and administrative expense.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Electro-Sensors, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Electro-Sensors, Inc. (the Company) as of December 31, 2017 and 2016, and the related statements of comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2017, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company's auditor since 2006.

Note 1. Nature of Business and Significant Accounting Policies

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 ultimate goal of manufacturing the industry-preferred product for every market served. The Company sells these products through an internal sales staff, manufacturer’s 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.

In addition, we may periodically make strategic investments in other businesses and companies, including investments that we believe would facilitate the development of technology complementary to our existing products or investments that we believe present good opportunities for the Company and its shareholders. Our primary focus is to remain an operating company and we do not intend to become an investment company. See Note 2 for additional information regarding the Company’s investments. The Company’s investments in securities are subject to normal market risks.

Significant accounting policies of the Company are summarized below:

Use of estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (US GAAP) 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 the 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.

Cash and cash equivalents

The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. Cash equivalents are invested in commercial paper, money market accounts and may, also, be invested in three month Treasury Bills. Cash equivalents are carried at cost plus accrued interest which approximates fair value.

The Company maintains its cash and cash equivalents primarily in two bank deposit accounts, which, at times, may exceed federally insured limits. The Company has not experienced any losses on these accounts. The Company believes it is not exposed to any significant credit risk on cash.

Trade receivables and credit policies

Trade receivables are uncollateralized customer obligations due under normal trade terms generally requiring payment within 30 days from the invoice date. Trade receivables are stated at the amount billed to the customer. Customer account balances with invoices over 90 days are considered delinquent. The Company does not accrue interest on delinquent trade receivables.

Payments of trade receivables are allocated to the specific invoices identified on the customer’s remittance advice or, if unspecified, are applied to the earliest unpaid invoices.

20

ELECTRO-SENSORS, INC.
NOTES TO FINANCIAL STATEMENTS

YEARS ENDED DECEMBER 31, 2017 AND 2016

(in thousands except share and per share amounts)

The carrying amount of trade receivables is reduced by an allowance for doubtful accounts that reflects management’s best estimate of the amounts that will not be collected. Management individually reviews all trade receivable balances that exceed 90 days from the invoice date and based on an assessment of current creditworthiness, estimates the portion, if any, of the balance that may not be collected. Management uses this information to estimate the allowance.

Available-for-sale securities

The Company’s investments have traditionally consisted of government debt securities and equity securities, primarily common stock. The estimated fair value of publicly traded equity securities is based on reported market prices or management’s reasonable market price when quoted prices are not available, and therefore subject to the inherent risk of market fluctuations.

Management determines the appropriate classification of securities at the date individual investments are acquired, and evaluates the appropriateness of this classification at each balance sheet date.

Since the Company generally does not make investments in anticipation of short-term fluctuations in market price, the Company classifies its investments in equity securities and treasury bills as available-for-sale. Available-for-sale securities with readily determinable values are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders’ equity and within accumulated other comprehensive gain (loss).

Realized gains and losses on securities, including losses from declines in value of specific securities determined by management to be other-than-temporary, are included in the statement of comprehensive income. Realized gains and losses are determined on the basis of the specific securities sold. There were no other-than-temporary impairments recognized in the years ended December 31, 2017 and 2016.

Fair value measurements

The Company’s policies incorporate the guidance for accounting for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. These policies also incorporate the guidance for fair value measurement related to nonfinancial items that are recognized and disclosed at fair value in the financial statements on a nonrecurring basis. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

| ● | Level 1 inputs are 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 are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

| ● | Level 3 inputs are unobservable inputs for the asset or liability.

The level in the fair value hierarchy within whic h a fair measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company currently has no nonfinancial or financial items that are measured on a nonrecurring basis.

The carrying value of cash equivalents, trade receivables, accounts payable, and other financial working capital items approximate fair value at December 31, 2017 and 2016 due to the short term maturity nature of these instruments.

Inventories

Inventories include material, labor and overhead and are valued at the lower of cost (first-in, first-out) or net realizable value.

YEARS ENDED DECEMBER 31, 2017 AND 2016

(in thousands except share and per share amounts)

Property and equipment

Property and equipment are stated at cost. Depreciation is provided over estimated useful lives by use of the straight-line method. Maintenance and repairs are expensed as incurred. Major improvements and betterments are capitalized.

Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require the Company to test a long-lived asset for possible impairment, the Company first compares undiscounted cash flows expected to be generated by an asset to the carrying value of the asset. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, the Company recognizes impairment to the extent that the carrying value of an asset exceeds its fair value. The Company determines fair value through various valuation techniques including, but not limited to, discounted cash flow models, quoted market values and third-party independent appraisals.

Estimated useful lives are as follows

|  | Years |
Equipment |  | 5-10 |
Furniture and Fixtures |  | 3 - 7 |
Building |  | 7-40 |

Intangible assets

Intangible assets are comprised of a non-compete agreement and the HazardPRO TM technology. The Company amortizes the cost of these intangible assets on a straight-line method over the estimated useful lives.

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, the product has been picked up by common carrier, the fee is fixed and determinable and collection of the resulting receivable is reasonably certain. Product revenues are recognized upon shipment because the contracts generally do not include post-shipment obligations. The Company may offer discounts that it generally records at the time of sale. In addition to exchanges and warranty returns, customers have limited refund rights. Historically, returns have been minimal and immaterial to the financial statements and are generally recognized when the returned product is received by the Company. In some situations, the Company receives advance payments from its customers. The Company defers the recognition of revenue associated with these advance payments until the product ships.

Advertising costs

The Company expenses advertising costs as incurred. Total advertising expense was $76 and $55 in 2017 and 2016, respectively.

Research and development

Expenditures for research and development are expensed as incurred. The Company incurred expenses of $812 and $767 in 2017 and 2016, respectively.

(in thousands except share and per share amounts)

Income taxes

The Company presents deferred income taxes on an asset and liability approach to financial accounting and reporting for income taxes. The Company annually determines the difference between the financial reporting and tax bases of assets and liabilities. The Company computes deferred income tax assets and liabilities for those differences that have future tax consequences using the currently enacted tax laws and rates that apply to the periods in which these laws are expected to affect taxable income. Income tax expense is the current tax payable or refundable for the period plus or minus the net change in the deferred tax assets and liabilities, excluding the portion of the deferred asset or liability allocated to other comprehensive gain (loss). Deferred taxes are reduced by a valuation allowance to the extent that realization of the related deferred tax asset is not certain. We recorded a valuation allowance of $28 and $0 at December 31, 2017 and 2016, respectively.

The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. The Company recognizes income tax positions at the largest amount that is more likely than not to be realized. The Company reflects changes in recognition or measurement in the period in which the change in judgment occurs.

The Company records interest and penalties related to unrecognized tax benefits in income tax expense.

Net income per common share

Basic earnings per share (EPS) excludes dilution and is determined by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities and other contracts to issue common stock were exercised or converted into common stock.

The following information presents the Company’s computations of basic and diluted EPS for the periods presented in the statements of comprehensive income.

|  | Income |  |  | Shares |  |  | Per share amount |
2017: |  |  |  |  |  |  |  |  |  |  |  |
Basic EPS |  | $ | 295 |  |  |  | 3,395,521 |  |  | $ | 0.09 |
Effect of dilutive stock options |  |  |  |  |  |  | 5,496 |  |  |  | 0.00 |
Diluted EPS |  | $ | 295 |  |  |  | 3,401,017 |  |  | $ | 0.09 |
2016: |  |  |  |  |  |  |  |  |  |  |  |
Basic EPS |  | $ | 202 |  |  |  | 3,395,521 |  |  | $ | 0.06 |
Effect of dilutive stock options |  |  |  |  |  |  | 424 |  |  |  | 0.00 |
Diluted EPS |  | $ | 202 |  |  |  | 3,395,945 |  |  | $ | 0.06 |

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”) 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 rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. At December 31, 2017, the Company had two stock-based compensation plans.

Recently Issued Accounting Pronouncements

Contract Revenue Recognition (Evaluating)

In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09 which was amended in August 2015 and during 2016. This standard amended the Revenue from Contracts with Customers (Topic 606) of the Accounting Standards Codification. The core principle of the new guidance is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. The guidance will be effective for the Company for reporting periods beginning after December 15, 2017. The standard will not have a material effect on the financial statements.

Reclassification

Certain items related to freight costs in the 2016 financial statements have been reclassified to conform to the 2017 presentation. These reclassifications had no effect on stockholders' equity, net income, or cash flows.

The fair value of the money market funds, commercial paper, and treasury bills is based on quoted market prices in an active market. Closing prices are readily available from active markets and are used as being representative of fair value. The Company classifies these securities as level 1. The only equity security owned by the Company is an investment in a limited-marketable company. There is an insignificant market for this limited-marketable company and the Company has determined the value based on financial and other factors, which are considered level 3 inputs in the fair value hierarchy. 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 change in level 3 assets at fair value on a recurring basis is summarized as follows:

|  | Years Ended December 31, |
|  | 2017 |  |  | 2016 |

Increase in value |  |  | 45 |  |  |  | 0 |
Ending Balance |  | $ | 45 |  |  | $ | 0 |

The 2017 increase in value is due to additional information obtained on the limited-marketable company.

The change in level 3 liabilities at fair value on a recurring basis is summarized as follows:

|  | Years Ended December 31, |
|  | 2017 |  |  | 2016 |

Credit to Earnings |  |  | (45 | ) |  |  | (260 | )
Ending Balance |  | $ | 150 |  |  | $ | 195 |

The 2017 and 2016 decreases in the contingent earn-out, which is recorded in general and administrative expenses, reflects the Company’s expectation of lower future contingent payments related to a general manufacturing sector slowdown as well as slower adoption of the Company’s wireless product offerings.

Note 8. Common Stock Options

Stock options

The 1997 Stock Option Plan (the “1997 Plan”) and 2013 Equity Incentive Plan (the “2013 Plan”) authorize the issuance of both nonqualified and incentive stock options. Payment for the shares may be made in cash, shares of the Company’s common stock or a combination thereof. Under the terms of the plans, incentive stock options and non-qualified stock options are granted at a minimum of 100% of fair market value on the date of grant and may be exercised at various times depending upon the terms of the option. All existing options expire 10 years from the date of grant or one year from the date of death.

Stock-based compensation

Under the 2013 Plan, the Company is authorized to grant options to purchase up to 600,000 shares of its common stock. As of December 31, 2017, options to purchase an aggregate of 300,000 shares were outstanding under the 2013 Plan, of which 265,000 shares were exercisable, and 300,000 shares were available for issuance pursuant to awards that may be granted under the plan in the future.

Under the 1997 Plan, the Company was authorized to grant options to purchase up to 450,000 shares of its common stock. As of December 31, 2017, options to purchase an aggregate of 7,500 shares were outstanding and exercisable under the 1997 Plan. The board terminated the plan in 2014. The existing grants may be exercised according to the terms of the grant agreements.

During the 2016 first quarter, the Company granted its Chief Executive Officer options to purchase 50,000 shares of common stock. The options were priced at fair market value and vested 20% on the grant date, with an additional 20% vesting on the first four anniversaries of the grant date. The options expire 10 years from the date of grant.

There were no options granted during 2017. The assumptions made in estimating the fair value of the options on the grant date based upon the BSM option-pricing model for the year ended December 31, 2016 are as follows:

Dividend Yield |  | 0.00%
Expected Volatility |  | 36.17%
Risk Free Interest Rate |  | 1.31%
Expected Life |  | 6 Years

The Company calculates expected volatility for stock options and other awards using historical volatility as the Company believes the expected volatility will approximate historical volatility.

The weighted average grant date fair value of options granted during the year ended December 31, 2016, under the 2013 Plan, was $33. The Company recognized compensation expense of approximately $51 and $74 during the years ended December 31, 2017 and 2016, respectively, in connection with the issuance of the options.

There were no options exercised during the years ended December 31, 2017 and 2016.

As of December 31, 2017, there was approximately $17 of unrecognized compensation expense under the 2013 Plan. The Company expects to recognize this expense over the next three years. To the extent the forfeiture rate is different than we have anticipated; stock-based compensation related to these awards will be different from our expectations.

Note 9. Benefit Plans

Employee stock ownership plan

The Company sponsors an employee stock ownership plan (“ESOP”) that covers substantially all employees who work 1,000 or more hours during the year. The ESOP has, at various times, secured financing from the Company to purchase the Company’s shares on the open market. When the Plan purchases shares with the proceeds of the Company loans, the shares are pledged as collateral for these loans. The shares are maintained in a suspense account until released and allocated to participant accounts. The Plan owns 135,490 shares of the Company’s stock at December 31, 2017. All shares held by the Plan have been released and allocated. No dividends were paid during the years ended December 31, 2017 and 2016. The Plan had no debt to the Company at December 31, 2017 or 2016.

The Company recognized compensation expense for contributions of $24 to the ESOP plan in 2017 and 2016.

In the event a terminated ESOP participant desires to sell his or her shares of the Company’s stock and the shares are not readily tradable, the Company may be required to purchase the shares from the participant at fair market value. In addition, at its election, the Company may distribute the ESOP’s shares to the terminated participant. At December 31, 2017, 135,490 shares of the Company’s stock, with an aggregate fair market value of approximately $549, are held by ESOP participants who, if terminated, would have rights under the repurchase provisions if the Company's stock were not readily traded. The Company believes that the market for its shares meets the ESOP requirements and that there would not be a current obligation to repurchase shares.

Profit sharing plan and savings plan

The Company has a salary reduction and profit sharing plan that conforms to IRS provisions for 401(k) plans. The Company may make profit sharing contributions with the approval of the Board of Directors. There were no profit sharing contributions by the Company in 2017 or 2016.

Evaluation of Disclosure Controls and Procedures

The person serving as our principal executive officer and principal financial officer evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”). Based on this evaluation, the person serving as the Company’s principal executive officer and principal financial officer has concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2017 to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Under Section 404 of the Sarbanes-Oxley Act of 2002, our management is required to assess the effectiveness of the Company’s internal control over financial reporting as of the end of each fiscal year and report, based on that assessment, whether the Company’s internal control over financial reporting is effective.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is designed to provide reasonable assurance as to the reliability of the Company’s financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore, internal control over financial reporting determined to be effective can provide only reasonable assurance with respect to financial statement preparation and may not prevent or detect all misstatements. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this assessment, the Company used the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in “Internal Control-Integrated Framework (2013).” These criteria are in the areas of control environment, risk assessment, control activities, information and communication, and monitoring. The Company’s assessment included extensive documenting, evaluating and testing the design and operating effectiveness of its internal control over financial reporting. Based on this evaluation, the person serving as the Company’s principal executive officer and principal financial officer has concluded that the Company’s internal controls were effective as of December 31, 2017.
