PART I


Item 1.	Business.

Introduction

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

In addition, through our subsidiary ESI Investment Company, we periodically make strategic investments in other businesses and companies, primarily when we believe that such investments will facilitate development of technology complementary to our existing products. Although we invest in other businesses and companies through our subsidiary ESI Investment Company, we do not intend to become an investment company and intend to remain primarily an operating company. Our primary investment is 273,267 shares of Rudolph Technologies, Inc., which is accounted for using the available-for-sale method.

Unless indicated otherwise, the terms “Company” and “ESI” when used herein, include Electro-Sensors, Inc. and its consolidated subsidiaries. As of December 31, 2012, ESI had two consolidated subsidiaries: ESI Investment Company and Senstar Corporation. Senstar Corporation does not have any business operations.

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 original products—speed monitoring systems—compare machine revolutions per minute or speed against acceptable rates as determined by the customer. The monitors generally have the same relative operating principle and use a non-contacting sensing head that translates the speed of a rotating shaft into analog readouts. The systems include a signal-generating pulser disc or wrap that attaches to a rotating shaft, the sensing device, and a control unit. 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 include a line of digital products that translate sensor impulses from its production monitoring systems into digital readouts indicating 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.

Three production monitoring devices that do not operate by measuring shaft speeds are also in the speed monitoring systems product line. These devices are the 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 below 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 (the West German manufacturer of control and interface devices), giving us rights to distribute in the United States the products manufactured by Motrona GmbH. These products interface with our products on various applications.

We believe that manufacturing companies can achieve significant savings in both time and materials by adding production monitoring and drive control technology to existing manufacturing processes to coordinate operation of related machines. We intend to continue to market our products to this “retro-fit” market and also to companies building new manufacturing machinery or processing systems.

Table of Contents

In 2008, we introduced our Electro-Sentry Hazard Monitoring System, which integrates our sensors for bearing temperature, belt misalignment, and shaft speed with a programmable logic controller and touch screen interface to create a complete system for hazard monitoring. By doing this, we are enabling our customer to locate which part of the material handling system is operating incorrectly, typically in less than ten seconds. This is done by using visual diagrams on the touch screen.

We expect to continue to expend resources in new product development and the marketing of new and existing products for use in production monitoring applications. We continue to expand our line of hazard monitoring products with new system displays and sensors to meet the requirements of a wider customer base. In 2012, we introduced the Electro-Sentry 16 hazard monitoring system and added new features to the Electro-Sentry 1 system. Other new products included a new ST420 shaft tachometer and several sensor mounting products.

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 are continuing to look for new industries to expand sales and may also consider acquiring compatible businesses as part of our growth strategy. 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 home office sales people who deal directly with customers and a number of manufacturer’s representatives and distributors located throughout the United States, Mexico, China, Canada, Chile, Bolivia, Colombia, Malaysia, Singapore, Great Britain, Australia, Egypt, El Salvador, Guatemala, Korea, Puerto Rico, Taiwan, and Turkey. 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 all major standard industrial classifications, including grain, feed, biofuels, food processing, chemicals, agricultural, 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 wide range of industrial products and attend several local, national and international tradeshows designated for the industry throughout the year. A corporate website and other related industry websites are also used for advertising and marketing purposes.

Competition

Competition for our monitoring products arises from a broad range of industrial and commercial businesses. Design, quality and multiplicity of application, rather than price, are the focus of competition in selling these products. We face substantial competition for our production monitoring systems. Many of these competitors are well established and larger than us in terms of total sales volume. Among our larger competitors are Danaher Controls, Red Lion Controls, Control Concepts, 4B Elevator Components Ltd., Durant Corporation, and Contrex, Inc. We believe our competitive advantages include that our products are sold as ready-to-install units and that our products have 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 production monitoring systems from various manufacturers and distributors. In some instances, these materials are manufactured in accordance with proprietary designs. Multiple sources of these supplies and materials are readily available, and we are not dependent on any single source for these supplies and materials. We have not experienced any 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 name “Electro-Sensors” is trademark registered with the U.S. Patent and Trademark Office, as Reg. No. 1,142,310. We believe our trademark has been and will continue to be useful in developing and protecting market recognition for our products.

We hold six patents relating to our production monitoring systems. Pursuant to a sales agreement with Motrona GmbH, a West-German manufacturer of control and interface devices, we hold rights to distribute in the United States the products manufactured by Motrona GmbH.

Table of Contents

Governmental Approvals

We are not required to obtain governmental approval of our products.

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 in related markets and to integrate state of the art technology into existing products. We incurred research and development expenses attributable to our production monitoring systems of $443,000 and $437,000 during 2012 and 2011, respectively. Our development projects are undertaken based upon the identified specific needs of our customer base.

Our future success is dependent 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.

Employees

As of March 22, 2013, we had 29 employees, of which 28 are full-time and one is part-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 and/or recruit key employees, product development, marketing and sales could be negatively impacted.

Fluctuations in Operating Results.

We have experienced fluctuations in our operating results in the past, and may 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. Some of these factors are: product competition and acceptance, timing of customer orders, cancellation of orders, the mix of products sold, downturns in the market and economic disruptions. Because fluctuations can happen, we caution investors that results of our operations for preceding periods may not be indicative of how we will perform in the future. There can be no assurance that we will experience continued earnings growth.

Further, investments held by our subsidiary, ESI Investment Company, are subject to significant positive and negative changes in value. In particular, our significant investment in Rudolph Technologies, Inc. has experienced substantial value fluctuations, both negative and positive, which are expected to continue. Our current intention is to continue to gradually liquidate our investment securities to finance our working capital needs as required.

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. The development of products requires us to commit financial resources, personnel and time, usually in advance of significant market demand for such products. In order to compete, we must anticipate both future demand and the technology available to meet that demand. There can be no assurance 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.

RESULTS OF OPERATIONS

Comparison of Fiscal Year 2012 vs. Fiscal Year 2011

Net Revenues

Net revenues for 2012 increased $383,000 to $6,498,000, or 6.3%, when compared to net revenues for 2011.The increase was spread across a broad range of our sensors and control products in the industrial markets that we serve and was driven largely by increased customer demand in connection with capacity expansion and plant retro-fit projects.

Cost of Sales

Our cost of sales increased $245,000 from $2,613,000 to $2,858,000, or 9.4%, when comparing fiscal year 2012 to fiscal year 2011. This increase was primarily a result of increased sales and increased costs of materials and labor. We continue our efforts to maintain or reduce production costs by manufacturing products in the most cost effective manner.

Table of Contents

Gross Margins

Gross margin for 2012 was 56.0% compared to 57.3% for the prior year. The slight decrease in the gross margin was due to the increased cost of materials and labor.

Operating Expenses

Total operating expenses increased by $47,000, or 1.7%, when comparing 2012 to 2011.

Selling and marketing costs decreased by $25,000, or 1.8%, when comparing 2012 to 2011. The decrease was due to a decrease in advertising and marketing expenses resulting from a change in the mix of direct advertising and tradeshows, offset by increases in wages and benefit expense (due to changes in the compensation package and higher commissions due to increased sales), travel (due to attendance at additional tradeshows and increased customer visits), trade shows (due to additional local and regional shows) and outside sales representatives’ commissions related to the increase in sales.

General and administrative costs increased by $66,000, or 6.9%, in 2012 compared to 2011. The increase was primarily due to an increase in expanded XBRL reporting requirements and depreciation expense due to upgrades in our enterprise software and related hardware. These increases were offset by decreases in expenses relating to repairs and maintenance of our building.

Research and development costs increased $6,000, or 1.4%, in 2012 when compared with 2011. The increase in research and development costs was due to an increase in lab testing fees for product testing and approval for hazardous locations and legal expenses related to patent applications, offset by decreases in the cost of lab materials and contract engineering expenses (due to the development and installation of the Electro-Sentry 1 system in 2011).

Operating Income

Operating income increased by $91,000 in 2012 from $740,000 to $831,000, an increase of 12.3% compared to 2011. The increase in operating income was mainly due to the increase in net sales.

Non-Operating Income

ESI Investment Company continues to provide us with an alternative source of earnings through investments in available-for-sale securities and other investments; however, our intent is to remain an operations-based company. Our investments in available-for-sale securities are subject to significant positive and negative changes in value. In addition to income from the sale of investments, we also realize interest income from our short-term holdings.

Non-operating income for fiscal year 2012 increased by $742,000 to $811,000. The increase was driven primarily by an increase in the gain on the sale of investments. In December 2012, the Company started liquidating its investment in Rudolph Technology, which resulted in a gain of $794,000. In December 2011, the Company’s investment in PPT Vision was liquidated, which resulted in a gain of $72,000. The 2011 gain from investments was offset by a loss of $18,000 on disposal of property and equipment related to building maintenance. There was no such loss on disposal of property in 2012.

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. Dividends on marketable equity securities are recognized in income when declared.

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

Interest income decreased $2,000, or 33.3%, when comparing fiscal year 2012 to the same period in 2011.

For the years ended December 31, 2012 and 2011, the Company recorded as other income earn-out payments related to the sale of the AutoData Systems Division to Auto Data Inc. of $13,000 and $3,000, respectively.

Table of Contents

Loss From Discontinued Operations

On September 16, 2011, the Company sold its entire interest in its AutoData Systems Division to Auto Data Inc. (ADI). The purchase price will be paid as an earn-out based on three percent of the software, hardware, and maintenance contracts that ADI sells over the next five years (four percent while ADI continues to occupy our building). The transaction was intended to allow us to focus on our core markets.

For the year ended December 31, 2011 the AutoData Systems Division had an operating loss, net of income taxes, of $50,000.

Net Income After Tax

We reported net income after tax for 2012 of $1,086,000, as compared to net income of $548,000 in 2011, an increase of $538,000, or 98.2%. Basic and diluted earnings per share from continuing operations were $0.32 and $0.31, respectively in 2012, compared to basic and diluted earnings per share from continuing operations of $0.17 in 2011.

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 $1,102,000 and $5,476,000 at December 31, 2012 and 2011, respectively. The decrease was mainly due to investing activities, as described below.

Cash from operating activities of $732,000 for the year ended December 31, 2012 was primarily a result of our net income adjusted for the gain on the sale of investments, and changes in accounts receivable, inventories, and income tax activity. Cash from operating activities increased $423,000 for the year ended December 31, 2012 when compared to the year ended December 31, 2011 due to an increase in net income of $538,000. The net change in trade receivables was due a decrease of $57,000 in the balance at December 31, 2012 compared to the prior year and an increase of $118,000 in the balance at December 31, 2011 when compared to the prior year. This was due to a decrease in outstanding accounts receivable balances as of December 31, 2012, partially due to the 2011 balance including a $71,000 receivable for the sale of PPT Vision stock. The net change in inventories was due to an increase of $102,000 in the balance at December 31, 2012 compared to the prior year and an increase of $188,000 in the balance at December 31, 2011 when compared to the prior year. The increase as of December 31, 2012 was smaller than the increase as of December 31, 2011 due to the type of new products introduced in 2012 compared to 2011. The net change in income taxes was due to an increase in the payable balance of $330,000 at December 31, 2012 compared to the prior year and an increase in the receivable balance of $37,000 at December 31, 2011 when compared to the prior year. The increase in the net payable was due to taxes due on gain on sale of investments. These increases were offset by the change in the gain on sale of investments. The gain on sale of investment was $794,000 for the year ended December 31, 2012 and $73,000 for the year ended December 31, 2011, a change in the adjustment to net income of $721,000.

Cash used in investing activities was $4,571,000 for the year ended December 31, 2012, compared to cash from investing activities of $5,106,000 for the year ended December 31, 2011. The significant increase in cash used in investing activities was due to an increase in net purchases of Treasury Bills with maturity dates of more than three months, with only a purchase of $5,249,000 during 2012, compared to net proceeds of $5,200,000 during 2011. During 2011, we had $9,500,000 in Treasury Bills mature and purchased $4,300,000 in Treasury Bills. We purchased $169,000 and $82,000 of property and equipment in the years ended December 31, 2012 and 2011, respectively. We received $874,000 on the sale of investments during 2012 compared to $2,000 during 2011.

Cash used in financing activities was $535,000 and $522,000 for the years ended December 31, 2012 and 2011, respectively. During the years ended December 31, 2012 and 2011, we paid aggregate dividends of $543,000 each year. During the years ended December 31, 2012 and 2011, we had $8,000 and $10,000, respectively, in stock purchases under our 1996 Employee Stock Purchase Plan. Also, in the year ended December 31, 2011, $11,000 in stock options were exercised.

Table of Contents

We intend that our ongoing cash requirements will be primarily used for capital expenditures, researching potential acquisitions, 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.

Our primary investment is 273,267 and 343,267 shares of Rudolph Technologies, Inc. (“Rudolph”), as of December 31, 2012 and 2011, respectively, listed on the Nasdaq stock market. The Rudolph investment is accounted for using the available-for-sale method. The fair value of the Rudolph investment totaled $3,673,000 and $3,134,000 as of December 31, 2012 and 2011, respectively. Our Rudolph shares are subject to fluctuations in price and could have a negative effect on our liquidity. Liquid securities are periodically sold as deemed appropriate by management. The market value of the Rudolph stock as of March 20, 2013 was $2,947,000.

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. Such 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 property and equipment, realizability of accounts receivable, and valuation of deferred tax assets/liabilities, inventory and investments. It is at least reasonably possible that these estimates may change in the near term.

Economic lives of property and equipment

We estimate the economic useful life of property and equipment used in the business. Expected asset lives may be shortened or an impairment recorded based on a change in the expected use of the asset.

Realizability of accounts receivable

We estimate our allowance for doubtful accounts based on prior history and the aging of our accounts receivable. 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 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.

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, 2012, and 2011, and the related consolidated statements of operations and comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2012. Electro-Sensors, Inc. and Subsidiaries’ 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, 2012 and 2011, and the results of their operations and their cash flows for each of the years in the two-year period ended December 31, 2012 in conformity with accounting principles generally accepted in the United States of America.

ELECTRO-SENSORS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2012 AND 2011

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 operations. 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 speed monitoring and motor control systems for industrial machinery. The Company utilizes 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’s products are sold through an internal sales staff, manufacturer’s representatives, and distributors to a wide variety of manufacturers, OEM’s and processors to monitor process machinery operations. The Company markets its products to a number of different industries located throughout the United States, Asia, Central America, Canada, and Europe.

In addition, through its subsidiary ESI Investment Company, the Company periodically makes strategic investments in other businesses and companies, primarily when the Company believes that such investments will facilitate development of technology complementary to the Company’s products. Although ESI, through its subsidiary ESI Investment Company, invests in other businesses or companies, ESI does not intend to become an investment company and intends to remain primarily an operating company. The Company’s primary investment is 273,267 shares of Rudolph Technologies, Inc. (“Rudolph”) which is accounted for using the available-for-sale method. See Note 2 for additional information regarding its 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 the consolidated financial statements, in accordance with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the amounts reported in the 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 property and equipment, realizability of accounts receivable, valuation of deferred tax assets/liabilities, inventory and investments. 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 such accounts. The Company believes it is not exposed to any significant credit risk on cash.

Trade receivables and credit policies

Accounts receivable are uncollateralized customer obligations due under normal trade terms requiring payment within 30 days from the invoice date. Accounts 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 accounts receivable.

Payments of accounts receivable 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 accounts receivable 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 accounts 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 will not be collected. Management uses this information to estimate the allowance.

Table of Contents

Available-for-sale securities

The Company’s investments consist of equity securities, primarily common stocks, government debt securities, commercial paper, and money market funds. The estimated fair value of publicly traded equity securities is based on quoted market prices, 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 such classification at each balance sheet date.

Since the Company does not buy and sell investments with the objective of generating profits on short-term fluctuations in market price, the investments in marketable equity securities have been classified as available-for-sale. 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 and within accumulated comprehensive income. Dividends on marketable equity securities are recognized in income on the ex-dividend date.

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. The Company’s 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 and cash equivalents, treasury bills, commercial paper, money market funds, trade receivables, accounts payable, and other working capital items approximate fair value at December 31, 2012 and 2011 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, 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, impairment is recognized to the extent that the carrying value 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.

Table of Contents

Revenue recognition

The Company recognizes revenue from the sale of its production monitoring equipment when persuasive evidence of an arrangement exists, the product has been delivered, the fee is fixed and determinable and collection of the resulting receivable is reasonably assured. The Company may offer discounts to its distributors or quantity discounts that are recorded at the time of sale. The Company recognizes revenue on products sold to customers and distributors upon shipment because the contracts do not include post-shipment obligations. In addition to exchanges and warranty returns, customers have refund rights. Our standard products are used in a wide variety of industries, returns are minimal and insignificant to the financial statements and are recognized when the returned product is received by the Company. In some situations, the Company receives advance payments from its customers. Revenue associated with these advance payments is deferred until the product is shipped or services performed.

Advertising costs

The Company expenses advertising costs as incurred. Total advertising expense was $89,000 and $184,000 for the years ended December 31, 2012 and 2011, respectively.

Research and development

Expenditures for research and development are expensed as incurred. We incurred expenses of $443,000 and $437,000 during the years ended December 31, 2012 and 2011, respectively.

Depreciation

The cost of property and equipment is depreciated on the straight-line method over the estimated useful lives.

Estimated useful lives are as follows


	Years

Equipment		3-10
Furniture and Fixtures		3-10
Building		7-40

Depreciation expense for the years ended December 31, 2012 and 2011 was $71,000 and $57,000, respectively.

Income taxes

Deferred income taxes are provided on an asset and liability approach to financial accounting and reporting for income taxes. The difference between the financial statement and tax bases of assets and liabilities is determined annually. Deferred income tax assets and liabilities are computed for those differences that have future tax consequences using the currently enacted tax laws and rates that apply to the periods in which they 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 liability allocated to other comprehensive income. Deferred taxes are reduced by a valuation allowance to the extent that realization of the related deferred tax asset is not assured. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely to be realized. Changes in recognition or measurement are reflected 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.

Table of Contents

Net income per common 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 operations.


	Income		Shares		Per share amount

2012:
Basic EPS from continuing operations	$	1,086,000		3,391,332	$	0.32
Effect of dilutive employee and director stock options				20,956
Diluted EPS from continuing operations	$	1,086,000		3,412,288	$	0.31

2011:
Basic EPS from continuing operations	$	598,000		3,387,192	$	0.17
Effect of dilutive employee and director stock options				18,546
Diluted EPS from continuing operations	$	598,000		3,405,738	$	0.17

Stock Compensation

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes-Merton (“BSM”) model with the assumptions included in the table below. 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, 2012, the Company had one stock-based employee compensation plan. On July 18, 2012, the Company granted each of its four outside directors options to purchase 2,500 shares of common stock, recognizing compensation expense of approximately $6,000 based on the grant date fair value.

The assumptions made in estimating the fair value of the options on the 2012 grant date based upon the BSM option-pricing model are as follows:


Dividend yield	0.00	%
Expected volatility	22.98	%
Risk free interest rate	2.21	%
Expected life	5 years

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

There were no options granted in the year ended December 31, 2011. During the year ended December 31, 2011, two employees exercised options to purchase a total of 4,500 shares of common stock. During the year ended December 31, 2012, one outside director forfeited options to purchase 5,000 shares of common stock.

Note 8. Common Stock Options and Stock Purchase Plan

Stock options

The 1997 Stock Option Plan includes 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 plan, incentive stock options are granted at 100% of fair market value on the date of grant and may be exercised at various times depending upon the terms of the option. The nonqualified stock options were granted to directors to purchase shares of the Company’s Common Stock. All existing options expire 10 years from the date of grant or one year from the date of death.

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


	Options Outstanding
	Number of Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (1)

Balance at January 1, 2011		16,480	$	3.06		2.2

As of December 31, 2012 and 2011, respectively there was no unrecognized compensation cost related to stock options that is expected to be recognized over a period of 1-2 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-based compensation

Pursuant to the 1997 Stock Option Plan (the “Option Plan”), the Company is authorized to grant options to purchase up to 450,000 shares of its Common Stock. As of December 31, 2012, options to purchase an aggregate of 21,980 shares were outstanding and exercisable under the Option Plan, and 250 shares were available for issuance pursuant to awards that may be granted under the Option Plan in the future.

Stock purchase plan

The 1996 Employee Stock Purchase Plan (the “ESPP”) allows employees to set aside up to 10% of their earnings for the purchase of shares of the Company’s Common Stock. The purchase price is the lower of 85% of the market value at the date of the grant or the exercise date, which is six months from the date of the grant. Under the ESPP, the Company is authorized to sell and issue up to 150,000 shares of its Common Stock to its full-time employees. During 2012 and 2011, 2,335 shares and 3,078 shares, respectively, were issued under the ESPP. At December 31, 2012, 71,956 shares were available for future issuance pursuant to the ESPP.

Note 9. Benefit Plans

Employee stock ownership plan

The Company sponsors an employee stock ownership plan (“ESOP”) that covers substantially all employees who work 1,000 or more hours during the year. The ESOP has, at various times, secured financing from the Company to purchase the Company’s shares on the open market. When the Plan purchases shares with the proceeds of the Company loans, the shares are pledged as collateral for its debt. The shares are maintained in a suspense account until released and allocated to participant accounts. The Plan owns 148,382 shares of the Company’s stock at December 31, 2012. All shares held by the Plan have been released and allocated. The dividends paid by the Company on shares held by the Plan are allocated to the participant accounts. The Plan had no debt to the Company at December 31, 2012.

The Company had compensation expense for contributions of $18,000 to the ESOP plan for the years ended December 31, 2012 and 2011.

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 their fair market value. At December 31, 2012, 148,382 shares of the Company’s stock, with an aggregate fair market value of approximately $559,000, are held by ESOP participants who, if terminated, would be subject to the repurchase requirement.

Profit sharing plan and savings plan

The Company has a salary reduction and profit sharing plan which conforms to IRS provisions for 401(k) plans. The Company may make profit sharing contributions with the approval of the Board of Directors. The Board of Directors approved Company contributions of $18,000 and $0 for the years ended December 31, 2012 and 2011, respectively, in addition to its matching of 401(k) salary reductions, which totaled $61,000 and $64,000 for 2012 and 2011, respectively.

Note 10. Discontinued Operations

On September 16, 2011, the Company sold its entire interest in its AutoData Systems Division to Auto Data Inc. (ADI). The purchase price will be paid as an earn-out based on three percent of the software, hardware, and maintenance contracts that ADI sells over the next five years (four percent while ADI continues to occupy our building). As of December 30, 2012 and 2011, ADI owed the Company approximately $0 and $3,000, respectively, under the earn-out. The amount is included in other assets on the balance sheet.

For the years ended December 31, 2012 and 2011, the Company recognized approximately $13,000 and $3,000, respectively, as other income from ADI under the earn-out agreement.

The division, a separate operating segment as described in Note 12, designed and marketed desktop software based systems that read hand printed characters, checkmarks and bar code information from scanned or faxed forms, in addition to collecting and reporting data from web forms.

Note 12. Segment Information

Prior to September 16, 2011, the Company had three reportable operating segments based on the nature of its product lines: Production Monitoring, AutoData Systems, and Investments. The AutoData Systems segment was sold on September 16, 2011 as described in Note 10.

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, 2012 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, 2012. 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.” 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, 2012.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the fourth quarter of 2012, which 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.
