Financial Statement Presentation

The condensed consolidated balance sheets and condensed consolidated statement of changes in stockholders’ equity as of March 31, 2016 and the related condensed consolidated statements of loss and comprehensive loss, and the condensed consolidated statements of cash flows for the periods ended March 31, 2016 and 2015 have been prepared by Company management. In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at March 31, 2016 and 2015 and for the periods then ended have been made.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2015 Annual Report to Shareholders on Form 10-K. The results of operations for the period ended March 31, 2016 are not necessarily indicative of operating results for the entire year.

The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates.

Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.

As part of the Company’s amended credit agreement with Wells Fargo Bank, the Company has pledged $5.0 million in long term investments against the line of credit. The Company tests for other-than-temporary losses on a quarterly basis and has considered the unrealized losses shown above to be temporary in nature. The Company intends to hold these investments until it can recover the full principal amount and has the ability to do so based on its other sources of liquidity. The Company expects these recoveries to occur prior to the contractual maturities. All unrealized losses as of March 31, 2016 were in a continuous unrealized loss position for less than twelve months and are not deemed to be other than temporarily impaired as of March 31, 2016.

The following table summarizes the estimated fair value of our investments, designated as available-for-sale and classified by the contractual maturity date of the securities as of March 31, 2016:

Stock-Based Compensation

Stock-Based Compensation [Abstract]

Stock-Based Compensation

NOTE 3 - STOCK-BASED COMPENSATION

Employee Stock Purchase Plan

Under the Company’s Employee Stock Purchase Plan (“ESPP”), employees are able to acquire shares of common stock at 85% of the price at the end of each current quarterly plan term. The most recent term ended March 31, 2016. The ESPP is considered compensatory under current Internal Revenue Service rules. At March 31, 2016, after giving effect to the shares issued as of that date, 94,790 shares remain available for purchase under the ESPP.

2011 Executive Incentive Compensation Plan

On March 28, 2011 the Board adopted and on May 19, 2011 the Company’s shareholders approved the Company’s 2011 Executive Incentive Compensation Plan (“2011 Incentive Plan”). The 2011 Incentive Plan authorizes incentive awards to officers, key employees and non-employee directors in the form of options (incentive and non-qualified), stock appreciation rights, restricted stock, restricted stock units, performance stock units (“deferred stock”), performance cash units, and other awards in stock, cash, or a combination of stock and cash. The 2011 Incentive Plan, as amended, allows the issuance of up to 2,000,000 shares of common stock.

During 2016, stock options covering 187,989 shares have been awarded to key executive employees and directors. These options expire seven years from the date of award and vest 25% each year beginning one year after the date of award. The Company also granted deferred stock awards of 93,828 shares to key employees during the first quarter of 2016 under the Company’s long-term incentive plan for performance over the 2016 to 2018 period. The actual number of shares of deferred stock, if any, that are ultimately earned by the respective employees will be determined based on achievement against performance goals at the end of the three year period ending December 31, 2018 and any shares earned will be issued in the first quarter of 2019 to those key employees still with the Company at that time.

At March 31, 2016, 110,091 shares have been issued under the 2011 Incentive Plan, 1,037,577 shares are subject to currently outstanding options, deferred stock awards, and unvested restricted stock units, and 852,332 shares are eligible for grant under future awards.

Stock Option Plan for Directors

Shares of common stock are reserved for issuance to non-employee directors under options granted by the Company prior to 2011 under its Stock Option Plan for Non-Employee Directors (the “Director Plan”). Under the Director Plan nonqualified stock options to acquire shares of common stock were automatically granted to each non-employee director concurrent with annual meetings of shareholders in 2010 and earlier years, with the exercise price of options granted being the fair market value of the common stock on the date of the respective shareholder meetings. Options granted under the Director Plan expire 10 years from date of grant. No options were granted under the Director Plan in 2014 or 2015. The Company amended the Director Plan in May 2011 to prohibit future option grants. As of March 31, 2016, there were 75,000 shares subject to outstanding options under the Director Plan.

1992 Stock Plan

Under the Company’s 1992 Stock Plan (“the Stock Plan”), shares of common stock may be issued pursuant to stock options, restricted stock or deferred stock grants to officers and key employees. Exercise prices of stock options under the Stock Plan cannot be less than fair market value of the stock on the date of grant. Rules and conditions governing awards of stock options, restricted stock and deferred stock are determined by the Compensation Committee of the Board of Directors, subject to limitations in the Stock Plan. The Company amended the Stock Plan in 2011 to prohibit future stock options or other equity awards.

At March 31, 2016, after reserving for stock options and deferred stock awards granted in prior years and adjusting for forfeitures and issuances during the year, there were 22,008 shares reserved for issuance under the Stock Plan. The Company has not awarded stock options or deferred stock under the Stock Plan since 2011.

We provide reserves for the estimated cost of product warranties at the time revenue is recognized. We estimate the costs of our warranty obligations based on our warranty policy or applicable contractual warranty, historical experience of known product failure rates, and use of materials and service delivery costs incurred in correcting product failures. Management reviews the estimated warranty liability on a quarterly basis to determine its adequacy. The actual warranty expense could differ from the estimates made by the Company based on product performance.

Debt

Debt	3 Months Ended
Debt	Mar. 31, 2016
Debt [Abstract]
Debt	NOTE 9 – DEBT Long-term Debt The mortgage on the Company’s headquarters building was payable in monthly installments and carried an interest rate of 6.83%. The mortgage matured on March 1, 2016 and the Company made payments totaling $104,000 in the first quarter of 2016 to fully settle the liability. The mortgage was secured by the building. Line of Credit The Company has a $10,000,000 line of credit from Wells Fargo Bank. The Company had $1,500,000 in outstanding borrowings against the line of credit at March 31, 2016 and no borrowings at March 31, 2015. Due to the revolving nature of loans under our credit facility, additional borrowings and periodic repayments and re-borrowings may be made until the maturity date. The total amount available for borrowings under our credit facility at March 31, 2016 was $8,500,000. Interest on borrowings on the credit line is at LIBOR plus 1.75% (1.9% at March 31, 2016). The credit agreement expires October 31, 2016 and is secured by assets of the Company. The Company has pledged $5.0 million in long term investments against the line of credit. Our credit agreement contains financial covenants including tangible net worth minimums and a minimum cash balance. The Company was in compliance with its financial covenants at March 31, 2016.

Income Taxes

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2016
Income Taxes [Abstract]
Income Taxes	NOTE 10 – INCOME TAXES In the preparation of the Company’s consolidated financial statements, management calculates income taxes based upon the estimated effective rate applicable to operating results for the full fiscal year. This includes estimating the current tax liability as well as assessing differences resulting from different treatment of items for tax and book accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on the balance sheet. These assets and liabilities are analyzed regularly and management assesses the likelihood that deferred tax assets will be recovered from future taxable income. In April 2016, we received notification from the Internal Revenue Service that they would be performing an examination of our 2012 and 2013 federal consolidated income tax returns. We do not expect that any settlement or payment that may result from the examination will have a material effect on our results of operations. At March 31, 2016 there was $226,000 of net uncertain tax benefit positions that would reduce the effective income tax rate if recognized. The Company records interest and penalties related to income taxes as income tax expense in the Condensed Consolidated Statements of Income. The Company is subject to U.S. federal income tax as well as income tax of multiple state and foreign jurisdictions. The tax years 2012-2015 remain open to examination by the Internal Revenue Service and the years 2011-2015 remain open to examination by various state tax departments. The tax years from 2012-2015 remain open in Costa Rica. The Company’s effective income tax rate was (15.7%) for the first three months of 2016. The effective tax rate differs from the federal tax rate of 35% due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes, provisions for interest charges for uncertain income tax positions, and changes in valuation allowances related to deferred tax assets. The foreign operating losses may ultimately be deductible in the countries in which they occurred; however the Company has not recorded a deferred tax asset for these losses due to uncertainty regarding the eventual realization of the benefit. The effect of the foreign operations was an overall rate decrease of approximately (24.9%) for the three months ended March 31, 2016. The Company's effective income tax rate for the three months ended March 31, 2015 was 26.1%, and differed from the federal tax rate due to state income taxes, foreign losses not deductible for U.S. income tax purposes and provisions for interest charges.

Segment Information

NOTE 11 – SEGMENT INFORMATION

Effective January 1, 2016, the Company realigned its business operations. As a result of the realignment, the Company has segregated its Transition Networks subsidiary TN EMEA (now renamed Net2Edge) as a separate operating segment. Following this realignment, the Company classifies its businesses into four segments as follows:

Suttle manufactures and markets connectivity infrastructure products for broadband and voice communications;

Transition Networks manufactures media converters, NIDs, NICs, Ethernet switches and other connectivity products that offer the ability to affordably integrate the benefits of fiber optics into any data network;

JDL Technologies provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, HIPAA-compliant IT services, and converged infrastructure configuration and deployment; and

Net2Edge provides business-critical systems for customers worldwide with a sharp focus on the telecommunications carrier and enables carriers to upgrade from legacy networks to high-speed services.

Management has chosen to organize the enterprise and disclose reportable segments based on our products and services. Intersegment revenues are eliminated upon consolidation. To conform to the 2016 presentation, the Company has reclassified 2015 segment information to present the Net2Edge business unit as a separate segment.

Information concerning the Company’s continuing operations in the various segments for the three month periods ended March 31, 2016 and 2015 is as follows:

Pensions [Abstract]

Pensions

NOTE 12 – PENSIONS

The Company’s U.K. based subsidiary Austin Taylor maintained a defined benefit pension plan. The Company does not provide any other post-retirement benefits to its employees. Components of net periodic benefit of the pension plans for the three months ended March 31, 2016 and 2015 were:



	Three Months Ended March 31
		2016		2015
Service cost	$	-	$	2,000
Interest cost		26,000		34,000
Expected return on assets		(24,000)		(45,000)
Settlement benefit		(43,000)		-
Net periodic pension benefit	$	(41,000)	$	(9,000)

The Company settled all its obligations under pension plan in the first quarter of 2016. The Company had contributed $650,000 toward the settlement of the pension into annuities in 2015, which resulted in the recognition of $1,222,000 of pension settlement costs in the income statement in the fourth quarter of 2015. The Company contributed an additional $68,000 toward the settlement in the first quarter of 2016, which resulted in a benefit of $43,000 recorded within operating expenses. As a result of the final settlement of all of its pension obligations, in the first quarter of 2016, the Company recorded $4,148,000 in pension liability adjustment gains previously recorded in accumulated other comprehensive income within operating expenses in the consolidated statement of income.

Net Income (Loss) Per Share [Abstract]
Net Income (Loss) Per Share	NOTE 13 – NET INCOME (LOSS) PER SHARE Basic net income per common share is based on the weighted average number of common shares outstanding during each year. Diluted net income per common share takes into effect the dilutive effect of potential common shares outstanding. The Company’s only potential common shares outstanding are stock options and shares associated with the long-term incentive compensation plans, which resulted in no dilutive effect for the three month periods ended March 31, 2016 and 2015. The Company calculates the dilutive effect of outstanding options using the treasury stock method. Due to the net losses in the first three months of 2015 and 2016, there was no dilutive impact from stock options or unvested shares. Options totaling 753,591and 522,922 were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2016 and 2015 because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 167,390 and 205,010 shares would not have been included for the three months ended March 31, 2016 and 2015 because of unmet performance conditions.

Fair Value Measurements

Fair Value Measurements [Abstract]

Fair Value Measurements

NOTE 14 – FAIR VALUE MEASUREMENTS

The accounting guidance establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows:

Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date.

Level 2 – Observable inputs such as quoted prices for similar instruments and quoted prices in markets that are not active, and inputs that are directly observable or can be corroborated by observable market data. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities.

Level 3 – Significant inputs to pricing that have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value of financial instruments.

Financial assets and liabilities measured at fair value as of March 31, 2016 and December 31, 2015, are summarized below:

Total	$	1,944,000	$	11,522,000	$	(142,000)	$	13,324,000

The estimated fair value of contingent consideration as of March 31, 2016 was $142,000, as noted above. The estimated fair value is considered a level 3 measurement because the probability weighted discounted cash flow methodology used to estimate fair value includes the use of significant unobservable inputs, primarily the contractual contingent consideration revenue targets and assumed probabilities. There was no change in the estimated contingent consideration during the three months ended March 31, 2016.

We record transfers between levels of the fair value hierarchy, if necessary, at the end of the reporting period. There were no transfers between levels during the three months ended March 31, 2016.
