Introduction 

PART I 

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.   

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 a complete line of monitoring and control systems for a wide range of industrial machine 
applications.  The systems measure machine production and operation rates, as well as 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 shaft speed. 

Our speed monitoring systems also include a line of products that measure production counts or rates, such as 
number of 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 sensors.  These 
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.  

     Vibration Monitoring Products  

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 1TM and Electro-Sentry 16TM hazard monitoring systems, which integrate 
our sensors for monitoring temperature, belt alignment, and shaft speed with programmable control logic to create a 
complete hazard monitoring system. These systems enable our customers to locate which part of their material 
handling system is operating incorrectly, typically in less than ten seconds.  

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 the user's processes.  The simple but 
powerful interface gives the user insight into the user's internal operations as the user strives to maximize safety and 
facility runtime, while minimizing costs associated with unscheduled maintenance and unplanned downtime.  
The HazardPRO system has been approved for use in hazardous dust environments by a third-party nationally 
recognized testing laboratory. 

The HazardPRO site system manager software efficiently collects data from sensors placed across a widely 
dispersed area.  We have also added a complete antenna pair mounting system to the product line 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 website, www.electro-sensors.com, provides significant product application information for our 
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, both nationally and internationally.   In 2021, we had international sales through distributors in the 
following countries; Canada, Mexico, Brazil, Chile, Guatemala, Germany, Peru, United Kingdom, Ukraine, Egypt, 
Saudi Arabia, United Arab Emirates, South Africa, Tunisia, India, Australia, China, the Republic of Korea, 
Vietnam, Malaysia, Philippines, Thailand, and Singapore. Sales to customers outside the United States represented 
approximately 11.6% of 2021 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 and applications within the industries we serve to expand sales and may also 
consider acquiring compatible businesses or product lines as part of our growth strategy.  In addition, we may make 
strategic investments that we believe present good opportunities for the Company and its shareholders. 

In addition to enhanced operational safety, 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 industry tradeshows throughout the year. We also use our corporate website and other 
related industry websites for advertising and marketing purposes. 

Competition 

We face substantial competition in the sale of our production monitoring sensors and systems from a broad range of 
industrial and commercial businesses. Among our competitors are 4B Elevator Components Ltd., Maxi-Tronic, Inc., 
Siemens Industry, Inc., and Ag Growth International Inc. (AGI). We believe our competitive advantages include our 
products' superior design and quality, and the fact that we sell our products as ready-to-install units that can be used 
in a wide range of applications. Our major challenges include the fact that several of our competitors are larger, may 
have better established names, have a broader range of sensing instruments, and have larger sales forces and capital 
resources. 

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 typically do not depend on any single source for these supplies and 
materials. In 2021, we experienced increased disruptions in our supply chain, resulting in difficulty sourcing parts.  
Additionally, we experienced price increases for many of the components used in our products.  In some situations, 
we are modifying product designs to accommodate new components that are more readily available.  There is no 
guarantee that we will continue to be successful in updating these designs and sourcing alternative components and 
material.  We are also experiencing delays in our shipping and transportation services, which may affect our ability 
to make timely deliveries to our customers.  We continue to closely watch lead times and availability of 
components.  We are continually assessing our inventory levels and may take actions as necessary to minimize 
disruptions to our supply chain such as maintaining larger levels of inventories than we have in the past, but these 
actions may not be successful if significant disruptions occur. 

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. 

6 

 
  
  
  
  
  
  
  
  
  
  
  
  
 
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. 

Seasonality 

Generally, the Company experiences seasonality in the sale of its products with the second and third calendar 
quarters historically the strongest. 

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 or business acquisitions.  In 
addition, we may make strategic or other investments that we believe present good opportunities for the Company 
and its shareholders, and we substantially increased these business development activities in the second half of 2021. 

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  

We invest in research and development programs to develop new products and to integrate state-of-the-art 
technology into our existing products. We undertake development projects based upon the identified specific needs 
of the markets we serve.  Our "Management's Discussion and Analysis of Financial Condition and Results of 
Operations” section describes the nature and amount of our research and development expenditures. 

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.

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. 

Human Capital  

As of December 31, 2021, the Company had 33 employees and two temporary employees, all of whom are full-time 
and based in the United States.  We consider our relations with our employees to be good. None of our employees 
are currently represented by a labor union. 

The Company views its employees and culture as keys to its success.  The Company aims to attract and retain 
qualified personnel and provides wages and benefits that are competitive locally to reward employees for 
performance.  The Company values innovation, inclusion and diversity, safety and engagement as they attract, 
develop, and retain the best talent. 

The health and safety of our employees is our top priority.  In response to the COVID-19 pandemic, the 
Company implemented a workplace safety plan, following CDC guidelines and federal and local mandates, to 
protect employees and minimize the potential risk of an outbreak within the Company.  We believe the Company 
has generally been successful implementing proactive measures to protect the health and safety of its employees 
while maintaining business continuity and high levels of service to our customers. 

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 adversely affected.  

Fluctuations in Operating Results 

We have experienced fluctuations in our past operating results and expect to experience fluctuations in the future.  
These fluctuations 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, supply chain disruptions, downturns in the markets 
we serve, geopolitical events, and economic disruptions such as weather related events or the effects of the COVID-
19 pandemic. 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.

Forward-Looking Statements 

The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements made 
by us or on our behalf. We have made, and may continue to make, forward-looking statements with respect to our 
business and financial matters, including statements contained in this document, other filings with the Securities and 
Exchange Commission, and reports to shareholders. Forward-looking statements generally include discussion of 
current expectations or forecasts of future events and can be identified by the use of terminology such as “believe,” 
“estimate,” “expect,” “intend,” “may,” “could,” “will,” and similar words or expressions. Any statement that does 
not relate solely to historical fact should be considered forward-looking.  

Our forward-looking statements generally relate to our growth strategy, future financial results, product 
development and sales efforts. We make forward-looking statements throughout this Annual Report, but primarily in 
this Item 1 and Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations. 
These include statements relating to our beliefs and expectations and intentions with respect to (i) our growth and 
profitability, (ii) our marketing and product development, (iii) our ability to continue to obtain parts and materials 
for our products from various manufacturers and distributors in a timely manner and at reasonable prices, (iv) the 
value of our intellectual property, (v) our competitive position in the marketplace, (vi) the effect of governmental 
regulations on our business, (vii) our employee relations, (viii) the adequacy of our facilities, (ix) our intention to 
develop new products, (x) the possibility of us acquiring compatible businesses or product lines as part of our 
growth strategy, (xi) our future cash requirements and use of cash, and (xii) the effect that the continuing COVID-19 
pandemic may have on the efficiency of our business operations, our customer base, and the domestic or worldwide 
economy. 

Forward-looking statements cannot be guaranteed and our actual results may vary materially due to the uncertainties 
and risks, known and unknown, associated with these statements, including our ability to successfully develop new 
products and manage our cash requirements. We undertake no obligation to update any forward-looking statements. 
We wish to caution investors that the following important factors, among others, in some cases have affected and in 
the future could affect our actual results of operations and cause these results to differ materially from those 
anticipated in forward-looking statements made in this document and elsewhere by us or on our behalf. We cannot 
foresee or identify all factors that could cause actual results to differ from expected or historical results. As such, 
investors should not consider any list of these factors to be an exhaustive statement of all risks, uncertainties or 
potentially inaccurate assumptions. These factors include our ability to:  
   ● successfully use our cash and liquid assets to develop or acquire new or complementary products or business 

lines to increase our revenue and profitability;  

  ● comply with any new government regulations that may be adopted to require companies to reduce carbon 

emissions or to disclose their carbon footprint, including the carbon footprint of components to manufacturers; 
   ● ensure that our operational systems, security systems and infrastructure, as well as those of third-party vendors, 

remain free from viruses or cyberattacks;  

   ● quickly and successfully adapt to changing industry technological standards;  
   ● comply with existing and changing industry regulations;  
   ● attract and retain key personnel, including senior management;  
  ● offset the effect of inflation on component prices and labor by increasing prices on finished products; 

   ● adapt  to  changing  economic  conditions  and  manage downturns  or  disruptions  in  the  economy  in  general; 
including  any  downturns  or  disruptions  that  may  result  from  events  such  as  the  outbreak  of  the COVID-19 
virus; and  

   ● keep pace with competitors, some of whom are much larger and have substantially greater resources than us.

The following paragraphs discuss the Company’s performance for years ended December 31, 2021 and 2020. 

Comparison of 2021 vs 2020 (dollars in thousands) 

Net Sales 

Net sales for 2021 were $8,607, an increase of $986, or 12.9%, from $7,621 in 2020.  The increase in sales was 
driven primarily by increased domestic orders for agricultural and industrial automation applications.  International 
sales during the year were flat as compared to the prior year, with increased sales to Canada primarily offset by 
decreased sales to China.

Gross Profit 

Gross profit for 2021 increased $747, or 19.0%, to $4,677 from $3,930 in 2020.  Gross margin in 2021 was 54.3% 
compared to 51.6% in 2020. The increase in gross margin was primarily due to improved factory and overhead 
utilization resulting from higher levels of manufacturing to support the increase in net sales.  

Operating Expenses 

Total operating expenses increased $102, or 2.5%, to $4,236 in 2021 from $4,134 in 2020, but decreased as a 
percentage of net sales to 49.3% from 54.3%.  The increase in operating expense dollars was primarily due to 
increases in legal and other professional fees and contract engineering for product enhancements. 

   ● Selling and marketing expenses decreased $239, or 14.8%, to $1,373 in 2021 from $1,612 in 2020, and 

decreased as a percentage of net sales to 16.0% from 21.2%. The decrease was primarily from lower sales 
headcount, partially offset by an increase in tradeshow related expenses. 

   ● General and administrative expenses increased $301, or 17.9%, to $1,987 in 2021 from $1,686 in 2020, and 

increased slightly as a percentage of net sales to 23.1% from 22.1%. The higher expenses were primarily due to 
legal and other professional fees related to the Company's increased corporate and business development activities, 
partially offset by a decrease in amortization expense related to HazardPRO technology which was fully amortized 
in the third quarter of 2021. 

   ● Research and development expenses increased $40, or 4.8%, to $876 in 2021 compared to $836 in 2020, 

but decreased as a percentage of net sales to 10.2% from 11.0%. The increase was primarily due to higher contract 
engineering costs related to product enhancements. 

Operating Income (Loss) 

Operating income was $441 in 2021 compared to an operating loss of $204 in 2020, an increase of $645, or 
316.2%.  The increase to operating income was primarily related to the increase in net sales and gross margin. 

Non-Operating Income (Expense) 

Non-operating income decreased $14 to $18 in 2021 from $32 in 2020, primarily as a result of less interest income 
earned as a result of lower interest rates on Treasury Bills, partially offset by an increase in the value of our 
investment in a non-publicly traded company. 

Equity securities are stated at fair value, and unrealized holding gains and losses are reported in our statement of 
comprehensive income (loss) in the non-operating income (expense) section.  All other 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 (loss). Realized gains and losses 
are determined on the basis of the specific securities sold. 

Income Taxes 

Income tax expense was $49 in 2021 compared to an income tax benefit of $48 in 2020. The increase in the tax 
expense was due primarily to net income before income taxes in 2021 compared to a net loss before income taxes in 
2020.  Detailed information on our income tax provision is provided in Note 11 to our financial statements. 

Net Income (Loss) 

We reported a net income of $410 in 2021 compared to net loss of $124 in 2020, an increase of $534, or 430.6%. Basic 
and diluted earnings per share were $0.12 and $-0.04 in 2021 and 2020, respectively.

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 $6,713 and $1,090 at December 31, 2021 and 2020, respectively. The increase was 
due to the fact that at December 31, 2021 we held the majority of available funds in assets defined as cash and cash 
equivalents.  At December 31, 2020, we held the majority of available funds in assets defined as investments. 
Working capital was $11,931 at December 31, 2021 compared to $11,323 at December 31, 2020. 

Cash generated from operating activities increased $438 to $769 in 2021 from $331 in 2020.  The increase was 
primarily due to an increase in net income, partially offset by net increases in trade receivables and inventories.  The 
2021 net income compared to the 2020 net loss was due to increased sales and gross margin.  The increase in trade 
receivables was primarily due to increased net sales.  The increase in inventories was due to the timing of inventory 
receipts.  We are purchasing key components as they are available due to increased lead times and uncertainty of 
deliveries. 

Cash generated from investing activities in 2021 was $4,860, compared to cash used in investing activities 
$8,020 in 2020. The increase in cash generated was due to a decrease in purchases of Treasury Bills classified as 
investments. In addition, we purchased $141 and $25 of property, equipment, and intangibles in 2021 and 2020, 
respectively. 

Cash used in financing activities during 2021 and 2020 was $6. The cash used was for principal payments on a 
financing lease on right-to-use assets.   

Subject to the following section, entitled COVID-19 Pandemic Discussion, the Company believes its ongoing cash 
usage requirements will be primarily for capital expenditures, potential acquisitions, investments we believe present 
good opportunities for the Company and its shareholders, research and development, working capital, and growth 
initiatives.  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.

COVID-19 Pandemic Discussion 

The COVID-19 pandemic continues to affect our operations, including limiting our ability to travel and fully engage 
customers at their facilities. While many regions of the US have reduced the severe restrictions implemented during 
2020, many customers continue to operate under modified restrictions based on the number of COVID-19 
cases.  The uncertainty surrounding the ongoing fluctuations in regional case counts creates uncertainty in our 
business and may negatively affect our 2022 financial results. 

We typically have robust sources for production components and materials.  However, we are increasingly 
experiencing significant disruptions in our supply chain, resulting in difficulty sourcing parts. Additionally, we are 
experiencing substantial price increases for many of the components used in our products. In certain situations, we 
are modifying product designs to accommodate new components that are more readily available.  There is no 
guarantee that we will continue to be successful in updating these designs and sourcing alternative components, and 
we could experience significant delays or run out of certain components and materials. We are also seeing delays in 
shipping and transportation services, which may adversely affect our ability to make timely deliveries to our 
customers. Furthermore, the labor market for qualified employees able to fill our production positions is challenging 
and may result in delays in filling open positions.  While we continue to closely manage each of these activities, our 
actions may not be successful and may result in a negative effect on our sales and profit margins. 

As of the date of this filing, we expect our business may be negatively affected but cannot currently determine the 
significance and duration of the pandemic on our business. 

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 affect reported amounts and disclosures. Changes 
in economic conditions or other business circumstances may affect the outcomes of management’s estimates and 
assumptions. 

14 

 
  
 
  
 
  
  
 
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, 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 recognize 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. Even though these equity securities were only 
valued at $56 at December 31, 2021, changes in the value of these equity securities could affect our profitability as 
the value fluctuates.  Any change in the value of these equity securities could have a material negative or positive 
effect on our profitability.  Changes in the value of our Treasury Bills do not affect our profitability until the 
Treasury Bill is sold.  At the time of sale, we recognize the interest earned on the Treasury Bill. 

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-Scholes-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.

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, 2021 
and  2020  and  the  related  statements  of  comprehensive  income  (loss),  changes  in  stockholders’  equity,  and  cash 
flows  for  each  of  the  years  in  the two-year  period  ended  December  31,  2021,  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, 2021 and 2020, and the results of its operations 
and  its  cash  flows  for  each  of  the  years  in  the two-year  period  ended December  31,  2021,  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.

Critical Audit Matters 

The  critical  audit  matters  communicated  below  are  matters  arising  from  the  current  period  audit  of  the  financial 
statements that were communicated or required to be communicated to the audit committee and that: (1) relate to 
accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging, 
subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion 
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, 
providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. 
Revenue Recognition 
Description of the Matter 

As described in Note 1 to the financial statements, the Company recognizes revenue when control of the promised 
goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be 
entitled to in exchange for those goods or services. 

The  Company  enters  into  certain  contracts  with  its  customers  that  may  contain  multiple  performance  obligations. 
Significant  judgment  may  be  required  by  the  Company  in  determining  revenue  recognition  specific  to  these 
contracts with multiple performance obligations, and includes the following: 

•          Determination  of  whether  products  and  services  are  considered  distinct  performance  obligations  that 

should be accounted for separately or combined as one unit of accounting. 

•          Determination  of  stand-alone  selling  prices  for  each  distinct  performance  obligation,  particularly  for 

products and services not sold separately.    

Given  these  factors,  the  related  audit  effort  in  evaluating  management’s  judgments  in  determining  revenue 
recognition for these customer agreements was extensive and required a high degree of auditor judgment.   
How We Addressed the Matter in Our Audit 
Our audit procedures related to product sales included the following, among others: 

•         We evaluated the Company’s accounting policies and related disclosures for compliance with applicable 

revenue recognition accounting guidance.   

•          We  obtained  an  understanding  of  the  design  and  implementation  of  internal  controls  related  to  the 
Company’s  revenue  recognition  process,  including  the  identification  of  performance  obligations  and 
allocation of transaction price. 

•         We performed analytical procedures to test the reasonableness of recorded balances.   
•         We performed procedures to test the transactions were recorded in the appropriate accounting period.   
•         We performed a proof of cash analysis comparing cash receipts to revenue recognized through the year.

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, with the 
ultimate goal of manufacturing the industry-preferred product for each 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 new relationships, or technology complementary to 
our existing products, or other investments that we believe present good opportunities for the Company and its 
shareholders. 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, 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 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.

NOTES TO FINANCIAL STATEMENTS 
YEARS ENDED DECEMBER 31, 2021 AND 2020  
(in thousands except share and per share amounts) 

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. 

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 due 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. 

As of December 31, 2021, the Company had no customers that exceeded 10% of the accounts receivable balance.  
As of December 31, 2020, there were two customer that accounted for approximately 21% of the accounts 
receivable balance. 

Investments 

Substantially all the Company’s current investments consist of government debt securities. The estimated fair value 
of publicly traded securities is based on reported market prices or management’s estimate of a 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 Treasury Bills as available-for-sale. Treasury Bills 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.  Equity securities with readily determinable values are stated at fair value. Unrealized gains and losses on 
equity securities are reported in the statement of comprehensive income in non-operating income. 

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 in non-operating 
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, 2021 and 2020.

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 non-financial 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 non-financial 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 which 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 non-financial 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, 2021 and 2020 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. 

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 

Autos   
Equipment  
Furniture and Fixtures  
Building

Intangible assets 

The intangible asset is a communication technology. The Company amortizes the cost of the intangible asset on a 
straight-line method over the estimated useful life.  At December 31, 2020, the Company also had the 
HazardPRO technology which was fully amortized in the 2021 third quarter. 

Revenue recognition 

At contract inception, the Company assesses the goods and services to be provided to a customer and identifies a 
performance obligation for each distinct good or service.   We also determine the transaction price for each 
performance obligation at contract inception.  Our contracts, generally in the form of a purchase order, specify the 
product or service that is to be provided 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.  Certain 
contracts have a second performance obligation, which typically is the initialization of the HazardPRO product.  For 
contracts that have multiple performance obligations, we allocate the transaction price to each performance 
obligation using the relative stand-alone selling price.  We generally determine stand-alone selling prices based on 
the observable stand-alone prices charged to customers.  We recognize product revenue at the point in time when 
control of the product is transferred to the customer, which typically occurs when we ship the products.  We 
recognize service revenue at the point in time when we have provided the service. 

Advertising costs 

The Company expenses advertising costs as incurred. Total advertising expense was $40 and $45 in 2021 and 2020, 
respectively. 

Research and development 

Expenditures for research and development are expensed as incurred. The Company incurred expenses of $876 and 
$836 in 2021 and 2020, respectively. 

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 have a valuation allowance on our 
deferred tax asset of $220 and $186 at December 31, 2021 and 2020 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 Company's 
change in judgment occurs. 

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

Net income (loss) 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 such as options were exercised or converted into common stock.  For the years ending December 31, 
2021 and 2020, respectively, options to purchase 283,082 and 332,500 weighted average common shares have been 
excluded from the diluted weighted average shares because their effect would be anti-dilutive. 

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

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, 2021, the Company had two stock-based compensation plans.

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 original 
terms  ranging  from  one  month to eight  months.   Treasury  Bills  with  an  original  maturity  date  of  three  months  or 
less are included within cash and cash equivalents on the balance sheet at December 31, 2021.   

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. 

Equity securities are measured at fair value and unrealized gains and losses are recognized in non-operating income.

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 equity securities owned by the Company are investments in two non-publicly traded companies, as a previously 
owned non-publicly traded company spun off its wholly owned subsidiary in October 2020.  Each shareholder in the 
parent company received the same number of shares in the spun off new company.  There is an undeterminable 
market for each of these two companies and the Company has determined the value based on financial and other 
factors, which are considered level 3 inputs in the fair value hierarchy.  

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

Note 9. 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, 2021, options to purchase an aggregate of 325,000 shares were outstanding under the 
2013 Plan, of which options to purchase 320,000 shares were exercisable, and 275,000 additional 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, 2021, 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. 

There were no options granted during the years ended December 31, 2021 and 2020.

NOTES TO FINANCIAL STATEMENTS  
YEARS ENDED DECEMBER 31, 2021 AND 2020  
(in thousands except share and per share amounts) 

The Company recognized compensation expense in connection with the issuance of options of approximately $5 and 
$6 during the years ended December 31, 2021 and 2020, respectively.  

There were no options exercised during the years ended December 31, 2021 and 2020. 

As of December 31, 2021, there was approximately $4 of unrecognized compensation expense under the 2013 Plan. 
The Company expects to recognize this expense over the next year. 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 10. 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 ESOP 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 ESOP owns 135,490 shares of the Company’s stock at 
December 31, 2021. All shares held by the ESOP have been released and allocated to participants' accounts. No 
dividends were paid during the years ended December 31, 2021 and 2020. The ESOP had no debt to the Company at 
December 31, 2021 or 2020. 

The Company recognized compensation expense for contributions of $30 and $24 to the ESOP plan for the years 
ended December 31, 2021 and 2020, respectively.   

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, 2021, 135,490 shares of the Company’s stock, with an aggregate fair market value of approximately 
$851, 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 because its stock is listed on the Nasdaq Capital 
Market it meets the ESOP requirements and that there would not be a current obligation for it to repurchase any 
distributed ESOP 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 2021 or 2020.

Item 9A.                Controls and Procedures. 

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, 2021 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, 2021. 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, 2021. 

Changes in Internal Control over Financial Reporting 

There have been no changes in the Company’s internal control over financial reporting that occurred during the 
fourth quarter of fiscal year 2021 that were identified in connection with management’s evaluation required by 
paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably 
likely to materially affect, the Company’s internal control over financial reporting.

March 31, 2022 

Dear Shareholders:        

               Welcome to the 2021 Electro-Sensors Annual Report.  We appreciate your interest in the company as we 
continue to deliver industry-leading machine monitoring sensors and hazard monitoring systems for global industrial 
and agricultural applications.  For over 50 years, our customers have relied on us to provide innovative and cost-
effective solutions, enabling efficient factory automation while helping to create increasingly safe work 
environments.  Our customers trust us to protect their most valuable assets - their people and facilities - and our 
amazing employees eagerly rise to this challenge!  

The year was noteworthy as we emerged from the depth of the COVID-19 pandemic and its many 
constraints.  Business conditions are improving and will eventually return to pre-pandemic norms. We are 
particularly excited to be able to travel once again and meet face to face with our customers.   We are grateful to our 
customers for their patience and partnership throughout these trying times, and proud of our employees for their 
commitment and persistence in the face of these challenges. 

We are pleased to report that in 2021 we achieved record annual revenue of $8.6 million, up 12.9% from 
the previous year.  This growth was driven by customers moving forward with both capacity upgrades and facility 
modernization plans after pausing some of these initiatives during the pandemic.  Additionally, gross profit 
improved to 54.3%, up from 51.6% in the prior year, as we drove higher levels of efficiency to support our increased 
revenue.   

These favorable results were achieved despite significant challenges associated with our supply chain.  

Many generally available components used in our products are now regularly out of stock or quoted with extremely 
long lead times.  Furthermore, we are experiencing significant inflationary pressure that has driven up component 
and raw material prices.  Although we are uncertain how long this unbalanced supply environment will persist, and 
how it may impact our ability to fulfill customer orders in a timely manner, we will continue to actively pursue all 
avenues for sourcing parts and identifying suitable substitutes as required.   

While 2022 appears to have its own set of challenges, including an ongoing conflict in Europe, we are 
thankful to have the pandemic significantly behind us and we remain encouraged with customer activity and the 
favorable demand to our products.  Electro-Sensors is built on an enduring foundation that is well positioned to 
adapt to these changing dynamics.  By staying close to our customers and continuing to deliver the robust products 
and thoughtful services for which we are famous, we believe we will continue to expand our reach and engage new 
and meaningful market opportunities. 

Thanks again for your continued support of Electro-Sensors.  Similar to last year, we will be conducting a 

virtual annual shareholder meeting on April 20, 2022.  Please see your proxy statement or visit our website 
(www.electro-sensors.com) for details on how to access and participate in the virtual meeting.  

              Sincerely, 

  David Klenk
