Note 1.  Basis of Presentation

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

This report should be read together with the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, including the audited financial statements and footnotes therein.

It is the opinion of management that the unaudited consolidated financial statements include all adjustments, consisting of normal recurring accruals, necessary to fairly state the financial position and results of operations as of March 31, 2015 and for the three-month period then ended in accordance with accounting principles generally accepted in the United States of America. The results of interim periods may not be indicative of results to be expected for the year.

Nature of Business

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.”

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. These products are sold through an internal sales staff, manufacturer’s representatives, and distributors to a wide variety of manufacturers and processors who use the products to monitor process machinery operations. The Company markets its products to a variety of industries located throughout the United States, Canada, Latin America, Europe, and Asia.

In addition, through its subsidiary ESI Investment Company, the Company periodically makes strategic investments in other businesses, primarily when the Company believes that these investments will facilitate development of technology complementary to the Company’s products. Although the Company, through ESI Investment Company, invests in other businesses, the Company does not intend to become an investment company and intends to remain primarily an operating company. See Note 4 for additional information regarding the Company’s investments. The Company’s investments in securities are subject to normal market risks.

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 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 do not include post-shipment obligations. The Company may offer discounts that are recorded 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 recognition of revenue associated with these advance payments is deferred until the product is shipped.

Available-for-Sale Securities

The Company’s investments consist of equity securities, primarily common stocks and government debt securities. 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 generally does not make investments in anticipation of short-term fluctuations in market prices, investments in equity securities and treasury bills are classified 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.

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 period realized. There were no other-than-temporary impairments in the three months ended March 31, 2015 and 2014.

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:

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, treasury bills, commercial paper, money market funds, trade receivables, accounts payable, and other financial working capital items approximate fair value at March 31, 2015 and December 31, 2014 due to the short maturity nature of these instruments.

Stock-Based Compensation

The Company uses the straight-line method to recognize compensation expense based on the estimated fair value on the date of grant over the requisite service period related to each award.  The fair value of stock options is estimated using the Black-Sholes-Merton (“BSM”) option pricing model, which incorporates certain assumptions, such as risk-free interest rate, expected volatility, expected dividend yield, and expected life of options.

Income taxes

Deferred income taxes are presented as assets or liabilities based on timing differences between financial reporting and tax reporting methods. The Company computes deferred income tax assets and liabilities, and reports differences that have future tax consequences using the currently enacted tax laws and rates that apply to the periods in which the Company expects these income tax assets and liabilities to affect taxable income. Income tax expense (benefit) 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 tax assets 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 March 31, 2015 or December 31, 2014.

Use of Estimates

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

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:

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 for the three months ended March 31, 2014.

In connection with the acquisition, the Company is obligated to pay an earn-out of up to $550, based on the level of revenues generated from the acquired products during the four calendar years following closing. The Company currently has 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 values 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 Company has not presented pro forma results of operations for the acquisition because the acquisition is not material to the Company’s consolidated results of operations, financial position or cash flows.

Note 3.  Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common shares outstanding and common stock equivalents outstanding during the period.

Note 4.  Investments

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

At March 31, 2015 and December 31, 2014, the Company’s significant investment in equity securities was 49,066 and 122,649 shares, respectively, of Rudolph, accounted for under the available-for-sale method. As of March 31, 2015 and December 31, 2014, the aggregate value of the Company’s Rudolph shares as reported on the Nasdaq Stock Exchange (ticker symbol RTEC) was $534 and $1,254, respectively, with an approximate cost of $6 and $16, respectively. During the three-month periods ended March 31, 2015 and 2014, the Company sold 73,583 and 49,179 shares, respectively, of Rudolph stock and reported gains of $815 and $547, respectively, in non-operating income.

Note 5.  Fair Value Measurements

The following table provides information on those assets and liabilities measured at fair value on a recurring basis.

March 31, 2015

December 31, 2014 

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 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. 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:

Note 9.  Stock-Based Compensation

The Company records compensation expense for stock options based on the estimated fair value of the options on the date of grant using the 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. The Company calculates expected volatility for stock options and awards using historical volatility because the Company believes the future volatility will approximate historical volatility. At March 31, 2015, the Company had two stock-based employee compensation plans. During the three-month periods ended March 31, 2015 and 2014, there were no stock options granted or exercised.

As of March 31, 2015, there was approximately $156 of unrecognized compensation expense. The Company expects to recognize this expense over the next three years. There was no intrinsic value in the options outstanding or exercisable as of March 31, 2015 as the option exercise prices were greater than the current fair market value as of that date.

Note 10. Segment Information

The Company has two reportable operating segments: Production Monitoring and Investments. The Production Monitoring Division manufactures and markets a complete line of production monitoring equipment, in particular speed monitoring and motor control systems for industrial machinery. ESI Investment Company holds investments in marketable and non-marketable securities.

The accounting policies of the segments are the same as those described in Note 1 of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. In evaluating segment performance, management focuses on sales and income before taxes. The Company has no inter-segment sales.

The following is financial information relating to the continuing operating segments:

Note 11.  Subsequent Events

During the second quarter of 2015, through April 28, 2015, the Company sold its remaining 49,066 shares of Rudolph stock for proceeds of $639 resulting in a gain on the sale of $632.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

FORWARD-LOOKING STATEMENTS

This Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including statements regarding our expectations, beliefs, intentions or strategies regarding the future. Forward-looking statements include, but are not limited to, statements relating to our marketing efforts or our efforts to accelerate growth; our business development activities; our efforts to maintain or reduce production costs; management’s intention that we not become an investment company; our expected use of cash on hand; our cash requirements; and the sufficiency of our cash flows. Any statement that is not based solely upon historical facts, including strategies for the future and the outcome of events that have not yet occurred, is considered a forward-looking statement.

All forward-looking statements in this document are based on information available to us as of the date of this form 10Q, and we assume no obligation to update any of these forward-looking statements, other than as required by law. Our actual results could differ materially from those in such forward-looking statements. The forward-looking statements we make in this Quarterly Report are subject to certain risks and uncertainties that could cause future results to differ materially from our recent results or those projected in the forward-looking statements, including the accuracy of management’s assumptions with respect to industry trends, fluctuations in industry conditions, the accuracy of management’s assumptions regarding expenses and our cash needs and those listed under the heading “Cautionary Statements” under “Item 1—Business,” in our Annual Report on Form 10-K for the year ended December 31, 2014.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make decisions based upon estimates, assumptions, and factors it considers relevant to the circumstances. These decisions include the selection of applicable accounting principles and the use of judgment in their application, and affect reported amounts and disclosures. Changes in economic conditions or other business circumstances may affect the outcomes of management’s estimates and assumptions. An in-depth description of our accounting estimates can be found in the interim financial statements included in this report and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014. No new estimates exist other than those discussed in our Annual Report.

The following table contains selected financial information, for the periods indicated, from our consolidated statements of comprehensive income expressed as a percentage of net sales.

The following paragraphs discuss the Company’s performance for the three months ended March 31, 2015 and 2014.

RESULTS OF OPERATIONS

Net Sales

Net sales for the three months ended March 31, 2015 increased $183,000, or 10.8%, when compared to the same period in 2014. This increase in sales was primarily due to a strong performance in the southwestern region of the US, which increased 50.3% over the same 2014 three-month period.  In addition, the company achieved greater than 30% growth in the shipment of system orders compared to the 2014 period.  The majority of these large orders were derived from our bulk material handling and grain and feed business segments, which continued to upgrade and add capacity at grain handling and storage facilities.

Gross Profit

Gross profit increased $92,000, or 9.5%, from $970,000 to $1,062,000. Gross margin, as a percentage of net sales, for the three months ended March 31, 2015 was 56.3%, versus 57.0% for the same period in 2014. The slight decrease in gross margin percentage was due to a change in product mix, as well as, additional product costs for the initial HazardPRO products and installation. We continue our efforts to maintain or increase gross margin by designing and manufacturing products in the most cost-effective manner.

Operating Expenses

Total operating expenses increased $124,000, or 13.7%, for the three months ended March 31, 2015 when compared to the same period of 2014. As a percentage of net sales, operating expenses increased to 54.6% in the 2015 three-month period compared to 53.2% in the same period for 2014.

Non-Operating Income (Expense)

Non-operating income increased by $265,000 for the three months ended March 31, 2015 compared to the same period for 2014. This increase was due to an increase in the gain on sale of available-for-sale securities. During the three months ended March 31, 2015 and 2014, we sold 73,583 and 49,179 shares, respectively, of Rudolph stock and recognized gains on the sales of $815,000 and $547,000, respectively. Subsequent to March 31, 2015 the Company liquidated substantially all of its equity securities and will deploy the proceeds from the sale of these securities in its operating business.

Income Before Income Taxes

Income before income taxes was $848,000 for the quarter ended March 31, 2015, representing an increase of $233,000, or 37.9%, when compared to income before income taxes of $615,000 for the quarter ended March 31, 2014.

The Production Monitoring Division had income before income taxes of $32,000 for the three months ended March 31, 2015, compared to $67,000 for the same period in 2014, a decrease of $35,000, or 52.2%. The 13.7% increase in operating expenses, partially offset by the 9.5% increase in gross profit, was the main reason for the decrease in net income before income taxes.

ESI Investment Company had income before income taxes of $816,000 for the three months ended March 31, 2015, compared to $548,000 for the same period in 2014, an increase of $268,000. This increase was a result of a greater gain on sale of available-for-sale securities in 2015 than in 2014 (see “Non-Operating Income (Expense)”). The net decrease in the unrealized value of available-for-sale securities was $436,000 for the three months ended March 31, 2015. The net decrease is due to the sale of Rudolph stock which resulted in $815,000 of gain on the sales during the quarter ended March 31, 2015. At March 31, 2015 ESI Investment Company had approximately $534,000 in unrealized gain on the Rudolph investment that is reported in Other Comprehensive Income (see Note 4 “Investments” in the notes to the accompanying consolidated financial statements).

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $1,631,000 at March 31, 2015 and $1,190,000 at December 31, 2014. The increase was mainly from investing activities, as the Company had more funds maturing from treasury bills than it invested in purchasing new bills.

Cash used in operating activities was $199,000 for the 2015 first quarter, compared to cash generated from operating activities of $137,000 in the 2014 first quarter. The $336,000 increase in cash used in operating activities was mainly due to the 2015 increase in trade receivables, inventories, accrued payables and accrued income taxes. The increase in trade receivables is due to increased sales. The increase in inventories is primarily due to the build-up of inventory for HazardPRO orders. The increase in accrued expenses was due to the timing of new hires and the accrual of their benefits. The increase in accrued income taxes resulted from the gain on sale of available-for-sale securities and the timing of estimated payments for 2015 and 2014.

Cash from investing activities was $1,021,000 and $36,000 for the three months ended March 31, 2015 and 2014, respectively. We generated $825,000 in proceeds on the sale of available-for-sale securities during the 2015 first quarter compared to $554,000 received in the 2014 first quarter. During the 2015 first quarter, the Company had net proceeds of Treasury Bills with a maturity date of more than three months of $201,000 compared to net purchases of $105,000 for the first quarter of 2014. In addition, the Company acquired the Harvest Engineering, Inc. (Harvest) wireless hazard monitoring technology and Insta-Link product family in February 2014, paying $400,000 and financing the remaining purchase price through a seller financed note.

Cash used in financing activities was $381,000 compared to cash generated from financing activities of $4,000 for the respective 2015 and 2014 first quarters. During the 2015 first quarter, we paid $381,000 on the long-term debt owed to Harvest for the technology purchased in February 2014, while the 2014 payment to Harvest was classified within investing activities. During the 2014 first quarter, we had $4,000 in stock purchases under the Employee Stock Purchase Plan.

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

Our primary investment at March 31, 2015 was 49,066 shares of Rudolph Technologies, Inc., listed on the Nasdaq Stock Exchange, accounted for using the available-for-sale method. The investment is subject to fluctuations in market price and could have a negative effect on our liquidity.

Off-balance Sheet Arrangements

As of March 31, 2015, the Company had no off-balance sheet arrangements or transactions.

Future Business Development Activities

The Company continues to seek growth opportunities, both internally through the Company’s existing portfolio of products, technologies and markets, as well as externally through technology partnerships or related-product acquisitions.  Although the Company is continuing to explore these external opportunities, it currently has no agreements or understandings with any third parties.
