Summary Of Significant Accounting Policies

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of business: Communications Systems, Inc. (herein collectively called “CSI,” “our” or the “Company”) is a Minnesota corporation organized in 1969 that operates directly and through its subsidiaries located in the United States and the United Kingdom. CSI is principally engaged through its Suttle business unit in the manufacture and sale of connectivity infrastructure products for broadband and voice communications and through its Transition Networks business unit in the manufacture and sale of core media conversion products, Ethernet switches, and other connectivity and data transmission products. Through its JDL Technologies business unit the Company provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, HIPAA-compliant IT services, and converged infrastructure configuration and deployment. Through its Net2Edge business unit, the Company enables telecommunications carriers to connect legacy networks to high-speed networks and services.

The Company classifies its businesses into four segments that correspond to these four business units. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation.

Principles of consolidation: The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and accounts have been eliminated.

Use of estimates: The presentation of 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 reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company uses estimates based on the best information available in recording transactions and balances resulting from operations. Actual results could differ from those estimates. The Company’s estimates consist principally of reserves for doubtful accounts, sales returns, warranty costs, asset impairment evaluations, accruals for compensation plans, self-insured medical and dental accruals, lower of cost or market inventory adjustments, provisions for income taxes and deferred taxes and depreciable lives of fixed assets.

Cash equivalents: For purposes of the consolidated statements of cash flows, the Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. As of December 31, 2017, the Company had $12,454,000 in cash and cash equivalents. Of this amount, $6,193,000 was invested in short-term money market funds that are not considered to be bank deposits and are not insured or guaranteed by the federal deposit insurance company (FDIC) or other government agency. These money market funds seek to preserve the value of the investment at $1.00 per share; however, it is possible to lose money investing in these funds. The remainder is operating cash and certificates of deposit which are fully insured through the FDIC.

Investments: Investments consist of certificates of deposit, corporate notes and bonds, and commercial paper that are traded on the open market and are classified as available-for-sale at December 31, 2017. Available-for-sale investments are reported at fair value with unrealized gains and losses excluded from operations and reported as a separate component of stockholders’ equity, net of tax (see Accumulated other comprehensive loss below).

Inventories: Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out method. Provision to reduce inventories to the lower of cost or net realizable value is made based on a review of excess and obsolete inventories, estimates of future sales, examination of historical consumption rates and the related value of component parts.

Property, plant and equipment: Property, plant and equipment are recorded at cost. Depreciation is computed using the straight-line method. Depreciation included in cost of sales and selling, general and administrative expenses for continuing operations was $3,156,000 and $3,609,000 for 2017 and 2016, respectively. Maintenance and repairs are charged to operations and additions or improvements are capitalized. Items of property sold, retired or otherwise disposed of are removed from the asset and accumulated depreciation accounts and any gains or losses on disposal are reflected in operations.

Intangible Assets: Intangible assets with indefinite useful lives are not amortized, but are tested at least annually for impairment.

Recoverability of long-lived assets: The Company reviews its long-lived assets periodically when impairment indicators exist as required under generally accepted accounting principles. Potential impairment is determined by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products. If the sum of the expected future net cash flows is less than the carrying value, an impairment loss would be measured by comparing the amount by which the carrying value exceeds the fair value of the asset.

Warranty: The Company 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 following table presents the changes in the Company’s warranty liability for the years ended December 31, 2017 and 2016, which relate to normal product warranties and a five-year obligation to provide for potential future liabilities for certain network equipment sales:



	Year Ended December 31
		2017		2016
Beginning balance	$	600,000	$	554,000
Amounts charged to expense		93,000		147,000
Actual warranty costs paid		(90,000)		(101,000)
Ending balance	$	603,000	$	600,000

Accumulated other comprehensive loss: The components of accumulated other comprehensive loss are as follows:



	Foreign Currency Translation		Unrealized (loss)/gain on securities		Accumulated Other Comprehensive Loss
December 31, 2016	$	(704,000)	$	17,000	$	(687,000)

Net current period change		79,000		(5,000)		74,000

December 31, 2017	$	(625,000)	$	12,000	$	(613,000)

The Company recognized $4,238,000 in foreign currency translation losses within the income statement during the first quarter of 2016 due to the substantial liquidation of our Austin Taylor subsidiary in the U.K. Refer to Note 7 for further information regarding the pension liability adjustment recognized in income in the first quarter of 2016. The functional currency of Austin Taylor and Net2Edge is the British pound. Assets and liabilities denominated in this foreign currency were translated into U.S. dollars at year-end exchange rates. Revenue and expense transactions were translated using average exchange rates. Suttle Costa Rica used the U.S. dollar as their functional currency.

Revenue recognition: The Company’s manufacturing operations (Suttle, Transition Networks and Net2Edge) recognize revenue when the earnings process is complete, evidenced by persuasive evidence of an agreement, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Revenue is recognized for domestic and international sales at the shipping point or delivery to customers, based on the related shipping terms. Risk of loss transfers at the point of shipment or delivery to customers, and the Company has no further obligation after such time. Sales are made directly to customers and through distributors. Payment terms for distributors are consistent with the terms of the Company’s direct customers. The Company records a provision for sales returns, sales incentives and warranty costs at the time of the sale based on historical experience and current trends.

JDL generally records revenue on hardware, software and related equipment sales and installation contracts when the revenue recognition criteria are met and products are installed and accepted by the customer. JDL records revenue on service contracts on a straight-line basis over the contract period, unless evidence suggests the revenue is earned in a different pattern. Each contract is individually reviewed to determine when the earnings process is complete.

Research and development: Research and development costs consist of outside testing services, equipment and supplies associated with enhancing existing products and developing new products. Research and development costs are expensed when incurred and totaled $3,639,000 in 2017 and $5,366,000 in 2016.

Net income 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 adjusts for 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 2017 and 2016. The Company calculates the dilutive effect of outstanding options and unvested shares using the treasury stock method. Due to the net loss in 2017 and 2016, there was no dilutive impact from outstanding stock options or unvested shares. Options totaling 1,144,159 would have been excluded from the calculation of diluted earnings per share for year ended December 31, 2017, because the exercise price was greater than the average market price of common stock during the year and deferred stock awards totaling 181,224 shares would not have been included because of unmet performance conditions. Options totaling 902,930 would have been excluded from the calculation of diluted earnings per share for year ended December 31, 2016, because the exercise price was greater than the average market price of common stock during the year and deferred stock awards totaling 133,982 shares would not have been included because of unmet performance conditions.

Share based compensation: The Company accounts for share based compensation awards on a fair value basis. The estimated grant date fair value of each stock-based award is recognized in income over the requisite service period (generally the vesting period). The estimated fair value of each option is calculated using the Black-Scholes option-pricing model.

Accounting standards issued:

In May 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard update on revenue recognition from contracts with customers. The new guidance will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. Under the new guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to receive in exchange for these goods or services. Due to the FASB’s July 2015 deferral of the standard’s required implementation date, the guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The Company will adopt the accounting standard using the modified retrospective transition approach. The modified retrospective transition approach will recognize any changes from the beginning of the year of initial application (2018) through retained earnings with no restatement of comparative periods.

The Company established an implementation team and engaged a third-party consultant to assist with our assessment of the impact of the new revenue guidance on our operations, consolidated financial statements and related disclosures and our implementation of the new standard. The Company completed an implementation plan that included (i) analyzing the new standard’s impact on the Company's contract portfolio; (ii) surveying the Company's businesses and various revenue streams; (iii) completing contract reviews; (iv) comparing its historical accounting policies and practices to the requirements of the new guidance; (v) identifying potential differences from applying the requirements of the new guidance to its contracts; and (vi) updating its accounting policy. The Company has completed the process of evaluating controls and new disclosure requirements and identifying and implementing appropriate changes to its business processes and systems to support recognition and disclosure under the new guidance.

Based on the Company’s analysis of open contracts as of the adoption date, there are no material impacts on the timing or amount of revenue recognized for product sales, which are primarily included within the Company’s Suttle and Transition Networks business units, because these contracts include only point-in-time performance obligations which are fully satisfied within the same reporting period, consistent with current revenue recognition. To the extent that future contracts include multiple performance obligations that are not fully satisfied and one or more were not priced at its standalone selling price (“SSP”), the Company will be required to perform an allocation of the transaction price which may result in a difference in the amount of revenue recognized in any period. There will also be no material change in the timing and amount of revenue recognized for service-related performance obligations that are satisfied over time within the Company’s JDL Technologies business unit. The Company also determined that the nature of its promise to its customers in certain contracts within its JDL Technologies business unit is to arrange for a third party to provide underlying goods or services (i.e., the Company is the agent in the transaction). Revenue allocated to these performance obligations will be recognized on a net basis, however, no such contracts were open as of the adoption date.

The Company adopted various practical expedients and policy elections related to the accounting for significant finance components, sales taxes, shipping and handling, costs to obtain a contract and immaterial promised goods or services, which will mitigate certain impacts of adopting this new standard.

The new standard requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows from customer contracts, specifically related to disaggregated revenue, contract balances and performance obligations. Additionally, as part of the Company’s implementation of the new standard, the Company implemented new internal controls to address risks associated with applying the five-step model, specifically related to judgments made in connection to performance obligations, estimated standalone selling prices and estimating variable consideration. The Company has also established monitoring controls to identify new sales arrangements and changes in its business environment that could potentially impact its current accounting assessment.

In February 2016, the FASB issued new accounting requirements regarding accounting for leases, which requires an entity to recognize both assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period, and early adoption is permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

In August 2016, the FASB issued new accounting guidance regarding the classification of cash receipts and payments in the Statement of Cash Flows. This guidance is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. The new standard is effective retrospectively on January 1, 2018, with early adoption permitted.

Accounting standards adopted:

In July 2015, the FASB issued an accounting standard on inventory, which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. This standard requires entities to compare the cost of inventory to one measure – net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The standard is effective for the annual period beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted, and is to be applied prospectively. The Company adopted this standard in the first quarter of 2017 with no material impact on its consolidated financial statements.

In November 2015, the FASB issued an accounting standard on deferred taxes, which removes the requirement to present deferred tax assets and liabilities as current and noncurrent on the balance sheet based on the classification of the related asset or liability, and instead requires classification of all deferred tax assets and liabilities as noncurrent. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption is permitted. The Company adopted this guidance in the first quarter of 2017 and other than the prescribed classification of all deferred tax assets and liabilities as noncurrent, there was no material impact on its consolidated financial statements.

In March 2016, the FASB issued a new accounting standard that changed certain aspects of accounting for share-based payments to employees, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017 with no material impact on our financial condition or results of operations.

In January 2017, the FASB issued new accounting guidance regarding the simplification of the test for goodwill impairment. The new standard eliminates the quantitative goodwill impairment analysis requirement to determine the fair value of individual assets and liabilities of a reporting unit to determine the amount of any goodwill impairment and instead permits an entity to recognize goodwill impairment loss as the excess of a reporting unit’s carrying value over the estimated fair value of the reporting unit, to the extent this amount does not exceed the carrying amount of goodwill. The new guidance continues to allow an entity to perform a qualitative assessment over goodwill impairment indicators in lieu of a quantitative assessment in certain situations. The standard will be effective for annual and interim periods beginning January 1, 2020, with early adoption permitted. The Company adopted this standard during 2017. As noted below in Note 5, the Company analyzed the reporting unit that had the goodwill and also analyzed the Company as a whole, including the Company’s four separate reporting units. Based on this analysis, the Company determined that the book value exceeded the overall fair value of the reporting units and the Company’s overall market value. As a result, the Company recorded a goodwill impairment charge totaling $1,463,000 during the second quarter of 2017.

Goodwill And Intangible Assets [Abstract]

Goodwill And Intangible Assets

NOTE 5 –GOODWILL AND INTANGIBLE ASSETS

Goodwill is required to be evaluated for impairment on an annual basis and between annual tests upon the occurrence of certain events or circumstances. In January 2017, the FASB issued new accounting guidance simplifying the goodwill impairment test. The new standard eliminates the quantitative goodwill impairment analysis requirement to determine the fair value of individual assets and liabilities of a reporting unit to determine the amount of any goodwill impairment and instead permits an entity to recognize goodwill impairment loss as the excess of a reporting unit’s carrying value over the estimated fair value of the reporting unit, to the extent this amount does not exceed the carrying amount of goodwill. The Company chose to adopt this standard early for the annual impairment analysis in 2017. The Company performed the first step of the previous two-step process, which requires that the fair value of the reporting unit be compared to its book value including goodwill. If the fair value is higher than the book value, no impairment is recognized. If the fair value is lower than the book value, an impairment adjustment must be recorded.

The Company performs its annual impairment analysis as of April 1 each year. The Company analyzed the reporting unit that had the goodwill and also analyzed the Company as a whole, including the Company’s four separate reporting units. Although JDL Technologies had been profitable for the prior eight quarters, the cyclical and unpredictable nature of revenues from its education sector raised issues in forecasting cash flows in future quarters used to estimate the reporting unit’s fair value. Based on this analysis of comparing the fair value of each reporting unit to the book value, and comparing the Company’s overall book value with its market capitalization, the Company determined that the book value exceeded the overall fair value of the reporting units as well as the Company’s overall market value. As a result, the Company recorded a goodwill impairment charge totaling $1,463,000 during the second quarter of 2017.

The changes in the carrying amount of goodwill for the year ended December 31, 2017 by segment are as follows:



	JDL Technologies

Gross goodwill		1,463,000
Accumulated impairment loss		(1,463,000)
Balance at December 31, 2017	$	-

As part of the overall annual impairment analysis noted above, the Company also reviewed other intangible assets for potential impairment. Based on this analysis, the Company deemed the intangible assets at Net2Edge related to customer relationships to be impaired and recorded a $154,000 impairment loss during the second quarter of 2017.

The Company’s identifiable intangible assets with finite lives are being amortized over their estimated useful lives and are included within other assets in the consolidated balance sheets and were as follows:

	$	811,000	$	(422,000)	$	-	$	(199,000)	$	190,000

Amortization expense on these identifiable intangible assets was $30,000 and $74,000 in 2017 and 2016, respectively.

Net periodic pension (benefit) cost	$	(41,000)

The Company settled all its obligations under the Austin Taylor 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.

Total rent expense was $474,000 and $620,000 in 2017 and 2016, respectively. At December 31, 2017, the Company was obligated under non-cancelable operating leases to make minimum annual future lease payments as follows:



Year Ending December 31:
2018	$	210,000
2019		112,000
2020		91,000
2021		91,000
2022		91,000
Thereafter		402,000
	$	997,000

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 $15,000,000 credit facility from Wells Fargo Bank. The Company had no outstanding borrowings against the credit facility at December 31, 2017 and 2016. 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 this credit facility at December 31, 2017 was $10,080,000, based on the borrowing base calculation. Interest on borrowings on the credit facility is at LIBOR plus 2.0% (3.6% at December 31, 2017). The credit agreement expires August 12, 2021 and is secured by assets of the Company. The credit agreement contains financial covenants including a minimum liquidity balance of $10,000,000. Liquidity is defined as the sum of unrestricted cash, marketable securities and the availability on the line of credit.

As of December 31, 2017, the Company had no other material commitments (either cancelable or non-cancelable) for capital expenditures or other purchase commitments related to ongoing operations.

Long-term compensation plans: The Company has a long term incentive plan that provides long-term competitive compensation to enable the Company to attract and retain qualified executive talent and to reward employees for achieving goals and improving company performance. The plan provides grants of “performance units” made at the beginning of performance periods and paid at the end of the period if performance goals are met. Awards were previously made every other year and are paid following the end of the cycle with annual vesting. Payment in the case of retirement, disability or death will be on a pro rata basis. The Company recognized (income)/expense of $(5,000) and $16,000 in 2017 and 2016, respectively. Accrual balances for long-term compensation plans at December 31, 2017 and 2016 were $11,000 and $16,000, respectively. There were no award payouts in 2017 and 2016. Awards for 2015 to 2017 cycles will be paid out 100% in stock. Awards under the 2016 to 2018 and 2017 to 2019 plans will be paid out 50% in cash and 50% in stock. The stock portion of these awards are treated as equity plans and included within the Stock Compensation footnote within the Deferred Stock Outstanding section below.

Other contingencies: In the ordinary course of business, the Company is exposed to legal actions and claims and incurs costs to defend against these actions and claims. Company management is not aware of any outstanding or pending legal actions or claims that would materially affect the Company’s financial position, results of operations, or cash flows.

Stock Compensation

NOTE 8 – STOCK COMPENSATION

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 2017, stock options covering 288,186 shares were awarded to key executive employees and non-employee directors, which options expire seven years from the date of award and generally vest 25% each year beginning one year after the date of award. The Company also granted deferred stock awards of 90,789 shares to key employees during 2017 under the Company’s long-term incentive plan for the 2017 to 2019 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 for each of the three years ending December 31, 2019 and the shares earned will be issued in the first quarter of 2020 to those key employees still with the Company at that time.

At December 31, 2017, 165,054 shares have been issued under the 2011 Incentive Plan, 1,315,294 shares are subject to currently outstanding options, deferred stock awards, and unvested restricted stock units, and 519,652 shares remained available for future issuance under the 2011 Incentive Plan.

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 3,000 shares of common stock were automatically granted to each non-employee director concurrent with annual meetings of shareholders in 2010 and earlier years and vested immediately. The exercise price of options granted was 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 have been granted under the Director Plan since 2011 when the Company amended the Director Plan to prohibit future option grants. As of December 31, 2017, there were 51,000 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 certain limitations in the Stock Plan. The Company amended the Stock Plan in 2011 to prohibit future equity awards. At December 31, 2017, after reserving for stock options and deferred stock awards described in the two preceding paragraphs and adjusting for forfeitures and issuances during the year, there were 10,230 shares reserved for issuance under the Stock Plan. The Company has not awarded stock options or deferred stock under the Stock Plan since 2011.

Stock Options Outstanding

The following table summarizes changes in the number of outstanding stock options under the Director Plan, Stock Plan and the 2011 Incentive Plan during the two years ended December 31, 2017.

Expected to vest December 31, 2017	1,172,659		8.63	4.55 years

The fair value of awards issued under the Company’s stock option plan is estimated at grant date using the Black-Scholes option-pricing model. The following table displays the assumptions used in the model.



	Year Ended December 31
	2017	2016
Expected volatility	30.4%	29.5%
Risk free interest rate	2.0%	1.5%
Expected holding period	6 years	6 years
Dividend yield	3.7%	9.1%

Total unrecognized compensation expense was $190,000 as of December 31, 2017, which is expected to be recognized over the next 2.3 years. The aggregate intrinsic value of all outstanding options, exercisable options, and options expected to vest (the amount by which the market price of the stock on the last day of the period exceeded the market price of the stock on the date of grant) was $0 based on the Company’s stock price at December 31, 2017. The intrinsic value of options exercised during the year was $0 in 2017 and 2016. Net cash proceeds from the exercise of all stock options were $0 for 2017 and 2016. There were no stock options exercised in 2017. The following table summarizes the status of stock options outstanding at December 31, 2017:



		Weighted Average	Weighted
		Remaining	Average
Range of Exercise Prices	Shares	Option Life	Exercise Price
$3.72 to $5.24	288,186	6.3 years	$	4.35
$5.25 to $7.49	289,200	5.3 years		6.61
$7.50 to $9.74	18,000	1.4 years		9.73
$9.75 to $11.99	439,833	3.6 years		11.34
$12.00 to $14.15	137,440	2.7 years		13.08

The Company receives an income tax benefit related to the gains received by officers and key employees who make disqualifying dispositions of stock received on exercise of qualified incentive stock options and on non-qualified options. The amount of tax benefit received by the Company was $0 and $0 in 2017 and 2016, respectively. The tax benefit amounts have been credited to additional paid-in capital.

Deferred Stock Outstanding

The following table summarizes the changes in the number of deferred stock shares under the Stock Plan and 2011 Incentive Plan over the period from December 31, 2015 to December 31, 2017:



		Weighted Average
		Grant Date
	Shares	Fair Value
Outstanding – December 31, 2015	126,427	$	11.73
Granted	102,161		7.28

Forfeited	(44,845)		10.28
Outstanding – December 31, 2017	190,524		6.60

The grant date fair value is calculated based on the Company’s closing stock price as of the grant date. As of December 31, 2017, the total unrecognized compensation expense related to the deferred stock shares was $22,000 and is expected to be recognized over a weighted-average period of 1.1 years.

Restricted Stock Units Outstanding

The following table summarizes the changes in the number of restricted stock units under the 2011 Incentive Plan over the period December 31, 2015 to December 31, 2017:



		Weighted Average
		Grant Date
	Shares	Fair Value
Outstanding – December 31, 2015	32,816	$	11.41

Vested	(13,341)		11.05
Outstanding – December 31, 2017	13,793		6.33

Compensation Expense

Share-based compensation expense is recognized based on the fair value of awards granted over the vesting period of the award. Share-based compensation expense recognized for 2017 and 2016 was $417,000 and $632,000 before income taxes and $271,000 and $411,000 after income taxes, respectively. Share-based compensation expense is recorded as a part of selling, general and administrative expenses.

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 December 31, 2017. The ESPP is considered compensatory under current rules. At December 31, 2017, after giving effect to the shares issued as of that date, 53,205 shares remain available for purchase under the ESPP.

Employee Stock Ownership Plan (ESOP)

All eligible employees of the Company participate in the ESOP after completing one year of service. Contributions are allocated to each participant based on compensation and vest 20% after two years of service and incrementally thereafter, with full vesting after six years. At December 31, 2017, the ESOP held 696,688 shares of the Company’s common stock, all of which have been allocated to the accounts of eligible employees. Contributions to the plan are determined by the Board of Directors and can be made in cash or shares of the Company’s stock. The 2017 ESOP contribution was $425,890 for which the Company issued 119,632 shares in March 2018. The 2016 ESOP contribution was $218,758 for which the Company issued 47,248 shares in 2017.

Common Stock [Abstract]
Common Stock	NOTE 9 – COMMON STOCK PURCHASES OF COMMUNICATIONS SYSTEMS, INC. COMMON STOCK In October 2008, the Company’s Board of Directors authorized the repurchase of shares of the Company’s stock pursuant to Exchange Act Rule 10b-18 on the open market, in block trades or in private transactions. At December 31, 2017, 411,910 additional shares could be repurchased under outstanding Board authorizations. SHAREHOLDER RIGHTS PLAN On December 23, 2009 the Board of Directors adopted a shareholders’ rights plan under which the Board declared a distribution of one right per share of common stock. Each right entitles the holder to purchase 1/100th of a share of a new series of Junior Participating Preferred Stock of the Company at an initial exercise price of $41. The rights expire on December 23, 2019. The rights will become exercisable only following the acquisition by a person or group, without the prior consent of the Board, of 16.5% or more of the Company’s voting stock, or following the announcement of a tender offer or exchange offer to acquire an interest of 16.5% or more. If the rights become exercisable, each rightholder will be entitled to purchase, at the exercise price, common stock with a market value equal to twice the exercise price. Should the Company be acquired, each right would entitle the holder to purchase, at the exercise price, common stock of the acquiring company with a market value equal to twice the exercise price. Any rights owned by the acquiring person or group would become void.

Austin Taylor Communications, Ltd. operates in the United Kingdom (U.K.) and is subject to U.K. rather than U.S. income taxes. Austin Taylor had no activity in 2017 and pretax income of $615,000 in 2016. At the end of 2017, Austin Taylor’s net operating loss carry-forward was $7,462,000. The Company remains uncertain whether it will be able to generate the future income needed to realize the tax benefit of the carry-forward. Accordingly, the Company has continued to maintain its deferred tax valuation allowance against any potential carry-forward benefit from Austin Taylor.

Net2Edge, Ltd., formally known as Transition Networks EMEA, Ltd., operates in the U.K. and is subject to U.K. rather than U.S. income taxes. Net2Edge, Ltd. had pretax losses of $2,616,000 and $2,114,000 in 2017 and 2016, respectively. At the end of 2017, Net2Edge, Ltd.’s net operating loss carry-forward was $4,471,000.

In 2007, Transition Networks China began operations in China and is subject to Chinese taxes rather than U.S. income taxes. Transition Networks China had no activity in 2017 and 2016. At the end of 2017, Transition Networks China's net operating loss carry-forward was $374,000. Due to the history of losses in China, the Company remains uncertain whether it will be able to generate the future income needed to realize the tax benefit of the carry-forward. Accordingly, the Company has continued to maintain its deferred tax valuation reserve against any potential carry-forward benefit. Transition Networks China ceased operations in 2014 and incurred minor non-operating expenditures in 2015 to close the operations. As of 2016, Transition Networks China no longer has any operational activity.

Suttle Costa Rica operated in Costa Rica and was subject to Costa Rica income taxes. In 2005, the Board of Directors of Suttle Costa Rica declared a dividend in the amount of $3,500,000 payable to the Company. The dividend and related “dividend reinvestment plan” qualify under Internal Revenue Code Sec. 965, which allows the Company to receive an 85% dividend-received deduction if the amount of the dividend is reinvested in the United States pursuant to a domestic reinvestment plan. The Company made the required qualified capital expenditures in 2006. No deferred taxes have been provided for the undistributed earnings. As of December 31, 2017, the amount of unremitted earnings outside of the United States was not significant to the Company’s liquidity and was available to fund investments abroad. The Company closed its Costa Rica facility in 2017 and no longer has any operational activity.

Suttle Costa Rica had a pretax loss of $1,582,000 in 2017 and pretax income of $463,000 in 2016. At the end of 2017, Suttle Costa Rica’s net operating loss carry-forward was $1,582,000.

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. As of December 31, 2017, the examination was complete. The settlement and payment that resulted from the examination did not have a material effect on our results of operations.

The provision for income taxes for continuing operations varied from the federal statutory tax rate as follows:

On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act tax reform legislation. This legislation makes significant change in U.S. tax law including a reduction in the corporate tax rates, changes to net operating loss carryforwards and carrybacks, and a repeal of the corporate alternative minimum tax. The legislation reduced the U.S. corporate tax rate from the current rate of 35% to 21%. As a result of the enacted law, the Company was required to revalue deferred tax assets and liabilities at the enacted rate. This revaluation resulted in a decrease of the deferred tax asset of $3,047,000 and a corresponding reduction of the valuation allowance.

The Company assesses available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ending December 31, 2017. Such objective evidence limits the ability to consider other subjective evidence such as the projections for future growth. On the basis of this evaluation, as of December 31, 2017, a valuation allowance of $8,713,000 has been recorded to reflect the portion of the deferred tax asset that is more likely to not be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as the Company’s projections for growth.

At December 31, 2017, the Company has a federal net operating loss carryforward from 2015 through 2017 activity of approximately $10,663,000 that is available to offset future taxable income and begins to expire in 2035.

During 2015, the Company engaged in a research and development tax credit study for the tax years 2011 to 2014. As a result of this study, the Company claimed $1,554,000 of federal and $1,024,000 of state research and development credits. The Company amended prior year tax returns to claim these credits and offset prior year taxes paid. Credits not utilized to reduce taxes are available to be carried forward. At December 31, 2017, the Company has an estimated federal research and development credit carryforward of approximately $467,000 and a state research and development credit carryforward of approximately $594,000.

The Company assesses uncertain tax positions in accordance with ASC 740. Under this method, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from these uncertain tax positions are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. The Company’s practice is to recognize interest and penalties related to income tax matters in income tax expense.

Changes in the Company’s uncertain tax positions are summarized as follows:



		2017		2016
Uncertain tax positions – January 1	$	207,000	$	217,000
Settlements		(101,000)		0
Expiration of statute of limitations		(65,000)		(10,000)
Uncertain tax positions – December 31, 2017	$	41,000	$	207,000

Included in the balance of uncertain tax positions at December 31, 2017 are $44,000 of tax benefits that if recognized would affect the tax rate. The Company’s unrecognized tax benefits will be reduced by $13,000 in the next twelve months due to statute of limitations expirations. There are no other expected significant changes in the Company’s uncertain tax positions in the next twelve months. The Company’s income tax liability accounts included accruals for interest and penalties of $4,000 at December 31, 2017. The Company’s 2017 income tax expense decreased by $2,000 due to net decreases for accrued interest and penalties.

The Company’s federal and state tax returns and tax returns it has filed in Costa Rica and the United Kingdom are open for review going back to the 2014 tax year.

Fair Value Measurements [Abstract]

Fair Value Measurements

NOTE 12 – FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

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.

As discussed in Note 5, we tested our goodwill for impairment as of April 1, 2017. As part of this impairment testing, the Company determined the fair value of the net assets of the JDL Technologies reporting unit, based primarily on discounted cash flows and forecasted future operating results, which represent Level 3 inputs. As a result of our analysis, the Company recorded a non-cash impairment charge of $1,463,000 to fully impair goodwill. A reconciliation of the beginning and ending balances of goodwill are included in Note 5.

Financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 and December 31, 2016, are summarized below:

Restructuring Charges [Abstract]
Restructuring Charges	NOTE 13 – RESTRUCTURING CHARGES During the year ended December 31, 2017, the Company recorded $2,285,000 in restructuring expense. This consisted of severance and related benefits costs due to the restructuring within the Suttle business segment, including costs related to the closure of the Costa Rica facility. We transferred substantially all of the production from Costa Rica to Minnesota by the end of the second quarter of 2017 and completed the closure in the third quarter of 2017. In the third quarter of 2017, we identified $505,000 of equipment, net of accumulated depreciation, that we determined we would no longer use as a result of consolidating our operations in the Minnesota location. We were not able to make this determination until we observed and assessed the condition of the equipment once it arrived in Minnesota. The loss on the disposal of this equipment is included in restructuring expense on the consolidated statement of loss and comprehensive loss. The Company paid $1,780,000 in restructuring charges during 2017 and had $0 in restructuring accruals recorded at December 31, 2017. We do not expect any material restructuring costs in 2018.
