Introduction 

PART I 

Electro-Sensors, Inc. (“we,” “us,” “our,” the “Company” or “ESI”) is engaged in manufacturing and selling industrial production 
monitoring and process control systems. 

In addition, through our former subsidiary ESI Investment Company, we periodically made strategic investments in other businesses 
and companies, primarily when we believed that these investments would facilitate the development of technology complementary to 
our existing products. During 2015, we sold substantially all our remaining investments in other businesses and companies.  Effective 
December 31, 2015, we merged ESI Investment Company and Senstar Corporation, a subsidiary with no business operations, into the 
parent company Electro-Sensors, Inc. 

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 several different types 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 speed monitoring systems compare revolutions per minute or speed against acceptable rates as determined by a customer. The 
systems vary in complexity, from a simple system that detects 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. 

The speed monitoring systems also include a line of products that measure production counts or rates, such as parts, gallons, or board 
feet.  The 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 also offer production monitoring devices that include a tilt switch, vibration monitor, and slide gate position monitor. A tilt switch 
is designed to alert the operator when a storage bin or production system reaches a certain capacity (e.g., when grain fills a silo).  A 
vibration monitor will alert an operator when the vibration of a machine in a production system exceeds or is less than a specified 
level.  The slide gate position monitor is used in plant operations to provide feedback of the position of a slide gate. As part of our 
Electro-Sentry Hazard Monitoring system, we also have temperature sensors that are used to monitor bearing temperature and belt 
misalignment. 

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. 

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. 

In 2008, we introduced our Electro-Sentry 1 hazard monitoring system, which integrates our sensors for monitoring temperature, belt 
misalignment, and shaft speed with a programmable logic controller and touch screen interface to create a complete system for hazard 
monitoring.  The system enables our customers to locate which part of their material handling system is operating incorrectly, 
typically in less than ten seconds, by using visual diagrams on a touch screen.  In 2012, we introduced the Electro-Sentry 16 hazard 
monitoring system and added new features to the Electro-Sentry 1 system.   

In 2013, the Company added ION Frequency/Discrete-In, a product that allows users to measure up to 12 shaft speeds and/or signal 
frequencies from pulse-frequency-output sensors.  This is our third ION product, completing the ION product line to support all ESI 
sensor products and providing the customer high-speed/accuracy signal acquisition at low cost and saved wiring costs.  The Company 
also expanded the Series 18 shaft speed sensors to include additional housings and connection options to reach a broader range of 
installations.  In addition, in 2013 we also introduced product upgrades for sensing capability and ruggedness on our Hall-effect 
sensors. 

In 2014, we introduced a process meter for analog output sensors, such as our TT420, temperature sensors, ST420, speed sensors, and 
SG1000, slide gate position monitor.

Additionally, in 2014, the Company purchased the Insta-Link wireless hazard technology monitoring system and product family, 
together with related technology and intellectual property rights,  from Harvest Engineering Inc., a privately held Illinois-based 
corporation, and its affiliated parties and owners (“Harvest”). The Company is marketing the wireless hazard monitoring products 
under its new HazardPROTM product line and manufacturing and servicing these products at its Minnetonka, Minnesota facility.  The 
Company agreed to pay $1,200,000 for the product line, of which $400,000 was paid at closing, and additional payments of $400,000 
will be paid on each of the first and second anniversary of the closing.  The final payment of $400,000 was made on February 18, 
2016.  Harvest may earn up to an additional $550,000 of purchase price, depending upon the achievement of revenue measures during 
the four calendar years following the closing. 

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 customers have diverse applications for our products in the grain, feed, bio-fuels, power generation, water utilities and waste 
water treatment, mining, chemical, and other processing areas.  We continue to look for new industries to expand sales and may also 
consider acquiring compatible businesses as part of our growth strategy.  We believe that a wide variety of organizations can 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. Our products are sold into both the “retro-fit” market and into new manufacturing or 
processing systems. 

Our corporate web site provides significant information and product application knowledge to existing and prospective customers and 
also direct knowledge to 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, Chile, Colombia, Guatemala, Peru, United Kingdom, Ukraine, Egypt, Saudi 
Arabia, Australia, China, Korea, Vietnam, Malaysia, Philippines, and Singapore.  Sales to customers outside the United States 
represent approximately 13% of sales in 2015.  The sensing and control units are sold under the Electro-Sensors, Inc. brand as a range 
of products from simple sensors to complex motor speed controllers.  These products are sold to businesses in a wide variety of 
industries, including agriculture, grain-handling, feed, biofuels, food processing, chemicals, mining, utility, forest products, steel, tire, 
glass and electronics.  Any business that uses machinery with a rotating shaft is a potential customer.   

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.   

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 our products are sold as ready-to-install units, and they 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 are not dependent 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 are not dependent 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 HazardPROTM trademark in the first quarter of 2014 and intend to register the trademark with the 
USPTO during 2016. 

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

The Company seeks to protect its 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 the Company would have adequate remedies for any breach, or that the Company’s 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. 

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 (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 $753 and $810 during 2015 
and 2014, 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. 

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. 

5 

 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
Employees 

As of March 9, 2016, 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 can happen, 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 
experience revenue or earnings growth. 

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

Our business depends upon periodically introducing new and enhanced products and solutions for customer needs. Our product 
development requires 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, 2015 and 2014. 

Comparison of 2015 vs. 2014  (in thousands) 

Net Sales 

Net sales increased $595 or 8.5%, to $7,636 in 2015 from $7,041 in 2014.  This increase was primarily driven by sales of HazardPRO 
wireless hazard monitoring systems following our receipt in early 2015 of third-party certification for installing HazardPRO systems 
into certain hazardous environments.  These HazardPRO systems are now deployed in a wide–range of agricultural and industrial 
applications, including grain handling and milling, animal nutrition and hardwood processing.   

We continue to see steady demand for our broad line of shaft speed switches and sensors as well as sensors for monitoring sliding 
gates and valves.  These sensors and switches are highly desired for their durability, safety and long-term value.  On a geographic 
basis, we experienced a 20% growth in sales to customers in the South Central U.S.   International markets remain an important part of 
our business, providing over 13% of our 2015 revenue from shipments into 45 countries.

Gross Profit 

Gross profit for 2015 increased $140, or 3.4%, to $4,226 from $4,086 in 2014.  Gross margin for 2015 was 55.3% compared to 58.0% in 
2014.  The slight decrease in the gross margin was primarily due to higher manufacturing costs on the initial HazardPRO products.  We 
expect HazardPRO manufacturing costs to continue to decrease through production efficiencies and increased purchasing volume. 

Operating Expenses 

Total operating expenses increased $241, or 6.5%, to $3,936 in 2015 compared to $3,695 in 2014.  This increase was due to the 
following:  

•  Selling and marketing expenses were relatively unchanged in 2015 compared to 2014, but decreased as a percentage of sales 
to 20.4% from 22.1%.  Increased travel costs related to promoting HazardPRO and personnel expenses were partially offset 
by a decrease in commissions paid to manufacturer’s representatives. 

•  General and administrative expenses increased $296, or 22.3%, to $1,625 in 2015 compared to $1,329 in 2014, and increased as 
a percentage of sales to 21.3% from 18.9%.  The increase was due primarily to amortization of the intangible assets related to the 
February 2014 acquisition of the HazardPRO technology and wages and benefits related to additional personnel.  Amortization 
expense on the HazardPRO technology for 2015 was approximately $211 compared to approximately $71 in 2014. 

•  Research and development expenses decreased $57, or 7.0%, to $753 in 2015 compared to $810 in 2014, and decreased as a 
percentage of sales to 9.9% from 11.5%.  The 2015 decrease was the result of lower wages and benefits due to reduced 
staffing levels and costs incurred in 2014 for prototype and development of the HazardPRO product line. 

Operating Income 

Operating income decreased $101 or 25.8%, to $290 in 2015 from $391 in 2014, and decreased as a percentage of sales to 3.7% from 
5.5%, due primarily to lower 2015 gross margin, which was slightly offset by lower operating expenses discussed above. 

Non-Operating Income 

Non-operating income increased $291 to $1,454 in 2015 from $1,163 in 2014, primarily as a result of additional realized gains on 
sales of shares of Rudolph Technologies, Inc. (“Rudolph”).  As of December 31, 2015, the Company has fully liquidated all holdings 
in Rudolph stock. 

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. 

Net Income After Tax 

We reported net income of $1,214 in 2015 as compared to net income of $1,094 in 2014, an increase of $120, or 11.0%.  Basic and 
diluted earnings per share were $0.36 and $0.33, respectively, in 2015, compared to basic and diluted earnings per share of $0.32 and 
$0.30, respectively, in 2014.

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 $569 and $1,190 at December 31, 2015 and 2014, respectively.  The decrease was mainly due to net 
cash used in operating activities, as described below.  Working capital was $9,941 at December 31, 2015 compared to $10,132 at 
December 31, 2014. 

Cash used in operating activities in 2015 was $306, compared to cash generated from operating activities of $263 in 2014, resulting in 
a decrease of cash from operating activities of $569.  The decrease resulted, in part, from an increase in inventories and a decrease in 
accrued expenses and income tax payable.  The inventory increase is primarily due to the build-up of inventory for anticipated 
HazardPRO system orders.  The decrease in accrued expenses is due to changes in compensation plans.  The decrease in income tax 
accruals is due to the timing of income tax payments. 

Cash generated from investing activities in 2015 was $66, compared to $581 cash used in 2014 investing activities.  The increase is 
primarily due to the receipt of $1,467 for sales of available-for-sale securities during 2015 compared to $1,178 during 2014.  In 
addition, the Company acquired the Harvest wireless hazard monitoring technology in February 2014 for $400,000 and financed the 
remaining purchase price through a seller-financed note.  

We used cash of $381 in 2015 financing activities compared to cash of $3 generated in 2014.  During 2015, we paid $381 on the long-
term note owed to Harvest, which was the first installment under the note payable agreement.  The final $400 installment on the note 
payable was paid on February 18, 2016. 

Our ongoing cash usage requirements will be primarily used for capital expenditures, potential acquisitions, 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.

CRITICAL ACCOUNTING ESTIMATES 

The preparation of our consolidated 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. 

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.   

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.    

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. 

Valuation of investments 
Our investments in equity 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.  

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. 

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors  
Electro-Sensors, Inc. and Subsidiaries 
Minnetonka, Minnesota 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Electro-Sensors,  Inc.  and  Subsidiaries  (the 
Company)  as  of  December  31,  2015  and  2014,  and  the  related  consolidated  statements  of  comprehensive  income, 
changes in stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2015. 
The Company’s management is responsible for these consolidated financial statements. Our responsibility is to express 
an opinion on these consolidated financial statements based on our audits. 

We conducted  our audits in accordance  with the standards of the Public Company Accounting Oversight Board (United 
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the 
consolidated financial statements are free of material misstatement. The Company is not required to have, nor were we 
engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  Our  audit  included  consideration  of  internal 
control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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.  An  audit  also  includes  examining,  on  a  test  basis,  evidence  supporting  the 
amounts  and  disclosures  in  the  consolidated  financial  statements,  assessing  the  accounting  principles  used  and 
significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe 
that our audits provide a reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position  of  Electro-Sensors,  Inc.  and  Subsidiaries  as  of  December  31,  2015  and  2014,  and  the  results  of  its  operations 
and its cash flows for each of the years in the two-year period ended December 31, 2015, in conformity with accounting 
principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
YEARS ENDED DECEMBER 31, 2015 AND 2014 
(in thousands except share and per share amounts) 

Note 1. Nature of Business and Significant Accounting Policies 

Nature of business: 

The accompanying consolidated financial statements include the accounts of Electro-Sensors, Inc. and its wholly-owned subsidiaries, 
ESI Investment Company and Senstar Corporation.  Senstar has no assets or operations.  As of December 31, 2015, these two 
subsidiaries were merged into the Electro-Sensors, Inc. parent company.  Intercompany accounts, transactions and earnings have been 
eliminated in consolidation. The consolidated entity is referred to as “the Company” or “ESI.”   

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 range of 
applications to monitor process machinery operations. The Company markets its products to a variety of different industries located 
throughout the United States, Canada, Mexico, Latin America, Europe, and Asia. 

In addition, through our former subsidiary ESI Investment Company, we periodically made strategic investments in other businesses, 
primarily when we believed that these investments would facilitate the development of technology complementary to our existing 
products. During 2015, we sold substantially all our remaining investments in other businesses and companies.  See Note 3 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 consolidated 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 consolidated 
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 in primarily one bank deposit account, 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
YEARS ENDED DECEMBER 31, 2015 AND 2014 
(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 equity securities, primarily common stocks and government debt 
securities.  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 income (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, 2015 
and 2014.  The Company sold substantially all of its available-for-sale securities during 2015. 

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 consolidated 
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 consolidated 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 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, 2015 and 2014 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 market.

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 a long-lived asset be 
tested 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.  Fair value is determined 
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 

Equipment 
Furniture and Fixtures 
Building 

Intangible assets 

  Years   

3-10  
3-10  
7-40  

Intangible assets are comprised of a noncompete agreement and the HazardPROTM 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 assured.  Product revenues are 
recognized upon shipment because the contracts generally do not include post-shipment obligations.  The Company may offer 
discounts that it 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 consolidated 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 $56 and $57 in fiscal 2015 and 2014, 
respectively. 

Research and development 

Expenditures for research and development are expensed as incurred.  The Company incurred expenses of $753 and $810 in fiscal 
2015 and 2014, 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 income (loss).  Deferred taxes are reduced by a 
valuation allowance to the extent that realization of the related deferred tax asset is not assured.  No valuation allowance was deemed 
necessary at December 31, 2015 and 2014. 

The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. The 
Company recognized 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.

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, 2015, the Company had two stock-based compensation 
plans.

Recently Issued Accounting Pronouncements 
Inventory Measurement (Evaluating)  
In July 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-11, which 
amended Inventory (Topic 330) Related to Simplifying the Measurement of Inventory of the Accounting Standards Codification. The 
amended guidance applies to all inventory except that which is measured using last-in, first-out (LIFO) or the retail inventory method. 
Inventory measured using first-in, first-out (FIFO) or average cost is included in the new amendments. Inventory within the scope of 
the new guidance should be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices 
in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent 
measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments will take effect for 
public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. For all 
other entities, the amendments in this update are effective for fiscal years beginning after December 15, 2016, and interim periods 
within fiscal years beginning after December 15, 2017. The new guidance should be applied prospectively, and earlier application is 
permitted as of the beginning of an interim or annual reporting period.  The Company does not expect this standard to have a material 
effect on its consolidated financial statements. 

Contract Revenue Recognition (Evaluating)  
In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09 which was amended in August 2015.  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 Company will apply the guidance using a modified retrospective approach.  The Company 
does not expect this standard to have a material effect on its consolidated financial statements. 

Note 2.  Business Combination 

On February 18, 2014, the Company acquired Harvest Engineering, Inc.’s wireless hazard monitoring technology system and Insta-Link 
product family, together with related technology and intellectual property rights, for a total purchase price of $1,643. 

The fair value of the consideration transferred on the acquisition date consisted of the following:

Note payable issued to seller (Note 9) 
Contingent earn-out liability 
Total consideration 

$ 

$

1,643 

The transaction was recorded as a business combination and the results of operations have been included in the consolidated statement of 
comprehensive income since the date of acquisition. Acquisition fees of approximately $15 incurred in connection with the transaction 
were recorded in operating expenses in 2014.   

In connection with the acquisition, the Company is obligated to pay an earn-out of up to $550 based upon the level of revenues generated 
from  the  acquired  products  during  the  four  calendar  years  following  closing.    At  the  time  of  acquisition,  the  Company  recorded  a 
contingent liability of $472 representing the fair value estimate of the earn-out based upon the Company’s projected likelihood of meeting 
the revenue targets.    

The following table summarizes the estimated fair value of the assets acquired at the acquisition date:

The noncompete agreement is being amortized over a five-year period.  The fair value of the noncompete agreement was estimated using 
a discounted cash flow model.  The unobservable inputs are considered Level 3 inputs in the fair value hierarchy.

The fair value of the money market funds, commercial paper, and treasury bills is based on quoted market prices in an active market. 
Available-for-sale securities include equity securities, except for the limited-marketable company, that are traded in an active market.  
Closing stock prices are readily available from active markets and are used as being representative of fair value.  The Company 
classifies these securities as level 1.  There is an insignificant market for the 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 liabilities at fair value on a recurring basis is summarized as follows:

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 

Pursuant to the 2013 Plan, the Company is authorized to grant options to purchase up to 300,000 shares of its common stock.  As of 
December 31, 2015, options to purchase an aggregate of 250,000 shares were outstanding, 165,000 shares were exercisable under the 
2013 Plan, and 50,000 shares were available for issuance pursuant to awards that may be granted under the plan in the future.  

Pursuant to 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, 2015, 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 but no 
additional options will be granted under the 1997 Plan. 

During the year ended December 31, 2014, options to purchase 11,980 shares of common stock expired for four employees. 

The following table summarizes the activity for outstanding incentive stock options under the 2013 Plan to employees of the 
company:

During the second quarter of 2014, the Company granted one outside director options to purchase 25,000 shares of common stock.  
The options were priced above 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 ten years from the date of grant.   

During the year ended December 31, 2014, one former outside director forfeited options to purchase 2,500 shares of common stock.

(1) The aggregate intrinsic value is calculated as approximately the difference between the weighted average exercise price of the 
underlying awards and the Company’s estimated current fair market value at December 31, 2015.  

The  weighted  average  grant  date  fair  value  of  options  granted  during  the  year  ended  December  31,  2014  was  $35.    The  Company 
recognized compensation expense of approximately $63 and $67 during the years ended December 31, 2015 and 2014, respectively, in 
connection with the issuance of the options.   

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, 2014 are as follows: 

Dividend Yield 
Expected Volatility 
Risk Free Interest Rate 
Expected Life 

0.00% 
44.11% 
2.02% 
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. 

There were no options exercised during the years ended December 31, 2015 and 2014. 

As of December 31, 2015, there was approximately $109 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.

Stock purchase plan 

The 1996 Employee Stock Purchase Plan (the “ESPP”) allowed employees to set aside up to 10% of their earnings for the purchase of 
shares of the Company’s common stock. The purchase price was the lower of 85% of the market value at the date of the grant or the 
exercise date, which was six months from the date of the grant.  Under the ESPP, the Company was authorized to sell and issue up to 
150,000 shares of its common stock to its full-time employees.  There were 81,653 shares issued under the plan.   The plan was 
terminated effective January 1, 2014. 

Note 12. 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 153,457 
shares of the Company’s stock at December 31, 2015. All shares held by the Plan have been released and allocated. No dividends 
were paid during the years ended December 31, 2015 and 2014. The Plan had no debt to the Company at December 31, 2015 or 2014. 

The Company recognized compensation expense for contributions of $24 and $18, respectively, to the ESOP plan in 2015 and 2014. 

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, the Company may 
distribute the ESOP’s shares to the terminated participant at the Company’s election.  At December 31, 2015, 153,457 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.  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 2015 or 2014.

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, 2015 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, 2015. 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, 2015.

March 7, 2016 

Dear Shareholders: 

Greetings and welcome to our 2015 Electro-Sensors Annual Report.  The year has certainly flown by and spring 
is once again in the air.  And while the return of the new season is rather predictable, it is likely one of the few things that 
remained predictable over the past year.  On a global scale, the year was characterized by accelerating uncertainty on 
many fronts, and in some cases, borderline chaos.  Tumultuous stock markets, currency valuations, commodity pricing 
and oil markets created a perfect storm that took hold in the latter part of the year.  While on the surface Electro-Sensors 
would appear to be somewhat disconnected from these global gyrations, we are certainly not immune to their economic 
impacts.  The breadth and depth of the disruptions significantly impacted our customers’ businesses, and in turn, Electro-
Sensors. 

In the face of these challenges, we are excited to be able to report record annual revenue of $7.6 million, or 8.5% 

above the prior year.  Our revenue growth was primarily driven by our new HazardPROTM wireless hazard monitoring 
product line which began shipping in the second quarter of 2015.  We believe HazardPRO is the industry’s most 
innovative and comprehensive wireless hazard monitoring system.  During 2015 we delivered over 20 HazardPRO 
systems and received outstanding customer reviews on both the new technology and related customer service.  Two of our 
customers have already ordered multiple HazardPRO systems, including an international customer that is now running 
three systems. 

As the year progressed, the first three quarters got off to a strong start before the global impacts began to be fully 

felt in the fourth quarter.  As the market turmoil increased, our customers tended to hold off on initiating strategic plant 
wide projects and instead focused on preserving capital and waiting out the storm.  We believe this pattern may change 
once global factors find some stability and the new North American agricultural season begins. 

In spite of the unexpected headwinds of late 2015 and early 2016, we remain encouraged and fully committed to 

being the leading machine and hazard monitoring provider for the markets we serve.  We will continue to innovate our 
existing product families, while at the same time looking for additional ways to bring industry leading solutions to related 
industrial markets. 

Thanks again for your continuing support of Electro-Sensors.  We look forward to seeing you at our annual 

shareholder meeting at 2:00pm on April 20, 2016, at the Sheraton Minneapolis West Hotel in Minnetonka. 

Sincerely, 

David Klenk
