Basis of Presentation and Significant Accounting Policies [Text Block] | NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements of Nortech Systems, Incorporated and Subsidiaries (“the Company”, “we”, “our”) have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Nature of Business Our manufacturing services include complete medical devices, printed circuit board assemblies, wire and cable assemblies, and complex higher-level electromechanical assemblies for a wide range of medical, industrial and defense and aerospace industries. We provide a full "turn-key" contract manufacturing service to our customers. All products are built to the customer's design specifications. We also provide engineering services and repair services. Our manufacturing facilities are located in Bemidji, Blue Earth, Merrifield, Milaca, and Mankato, Minnesota as well as, Monterrey, Mexico and Suzhou, China. Products are sold to customers both domestically and internationally. Principles of Consolidation The consolidated financial statements include the accounts of Nortech Systems Incorporated and its wholly-owned subsidiaries, Manufacturing Assembly Solutions of Monterrey, Inc. and Nortech Systems Hong Kong Company, Limited and its subsidiary, Nortech Systems Suzhou Company, Limited. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us 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 our consolidated financial statements. Estimates also affect the reported amounts of revenue and expense during the reporting period. Significant items subject to estimates and assumptions include the valuation allowance for inventories, allowance for doubtful accounts, realizability of deferred tax assets, goodwill impairment and long-lived asset impairment testing. Actual results could differ from those estimates. Restricted Cash Cash and cash equivalents classified as restricted cash on our consolidated balance sheets are restricted as to withdrawal or use under the terms of certain contractual agreements. The December 31, 2020 balance included cash collateral required to be held against our corporate employee purchasing card program and lockbox deposits that are temporarily restricted due to timing at the period end. The lockbox deposits are applied against our line of credit the next business day. As of December 31, 2020 we had outstanding letters of credit for $500 in total to Essjay Bemidji Holdings, LLC and Essjay Mankato Holdings, LLC. Restricted cash as of December 31, 2020 and December 31, 2019 was $3,212 and $309, respectively. Accounts Receivable and Allowance for Doubtful Accounts We grant credit to customers in the normal course of business. Accounts receivable are unsecured and are presented net of an allowance for doubtful accounts. The allowance for doubtful accounts was $343 and $335 at December 31, 2020 and 2019, respectively. We determine our allowance by considering a number of factors, including the length of time accounts receivable are past due, our previous loss history, the customers' current ability to pay their obligations to us, and the condition of the general economy and the industry as a whole. We write-off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. Inventories Inventories consist of finished goods, raw materials and work-in-process and are stated at the lower of average cost (which approximates first -in, first -out) or net realizable value. Costs include material, labor, and overhead required in the production of our products. Inventory reserves are maintained for inventories that may have a lower value than stated or quantities in excess of future production needs. We regularly review inventory quantities on-hand for excess and obsolete inventory and, when circumstances indicate, incur charges to write down inventories to their net realizable value. The determination of a reserve for excess and obsolete inventory involves management exercising judgment to determine the required reserve, considering future demand, product life cycles, introduction of new products and current market conditions. Inventories are as follows:
|  | 2020 |  |  | 2019 |
Raw materials |  | $ | 14,865 |  |  | $ | 15,245 |
Work in process |  |  | 969 |  |  |  | 479 |
Finished goods |  |  | 242 |  |  |  | 41 |
Reserves |  |  | (2,159 | ) |  |  | (1,486 | )
Total |  | $ | 13,917 |  |  | $ | 14,279 |
Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Additions, improvements and major renewals are capitalized, while maintenance and minor repairs are expensed as incurred. When assets are retired or disposed of, the assets and related accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected in operations. Leasehold improvements are depreciated over the shorter of their estimated useful lives or their remaining lease terms. All other property and equipment are depreciated by the straight-line method over their estimated useful lives, as follows:
Buildings (in years) |  | 39 |
Leasehold improvements (in years) |  | 3 - 15 |
Manufacturing equipment (in years) |  | 3 - 7 |
Office and other equipment (in years) |  | 3 - 7 |
Property and equipment at December 31, 2020 and 2019:
|  | 2020 |  |  | 2019 |
Land |  | $ | 176 |  |  | $ | 360 |
Building and Leasehold Improvements |  |  | 5,999 |  |  |  | 9,660 |
Manufacturing Equipment |  |  | 22,685 |  |  |  | 21,908 |
Office and Other Equipment |  |  | 7,148 |  |  |  | 7,192 |
Accumulated Depreciation and Amortization |  |  | (29,582 | ) |  |  | (29,539 | )
Total Property and Equipment, Net |  | $ | 6,426 |  |  | $ | 9,581 |
Goodwill and Other Intangible Assets In accordance with ASC 350, Goodwill and Other Intangible Assets, goodwill is not amortized but is required to be reviewed for impairment at least annually or when events or circumstances indicate that carrying value may exceed fair value. We test impairment annually as of October 1st. In testing goodwill for impairment, we perform a quantitative or qualitative impairment test, including computing the fair value of the reporting unit and comparing that value to its carrying value. If the fair value is less than its carrying value, then the goodwill is determined to be impaired. In the event that goodwill is impaired, an impairment charge to earnings would become necessary. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. Prior to completing the quantitative analysis described above, we have the option to perform a qualitative assessment of goodwill for impairment to determine whether it is more likely than not (a likelihood of more than 50% ) that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. If we conclude the fair value is more likely than not less than the carrying value, we perform the quantitative analysis. Otherwise, no further testing is needed. Long-Lived Asset Impairment We evaluate long-lived assets, primarily property and equipment, as well as the related depreciation periods, whenever current events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability for assets to be held and used is based on our projection of the undiscounted future operating cash flows of the underlying assets or asset group. To the extent such projections indicate that future undiscounted cash flows are not sufficient to recover the carrying amounts of related assets, a charge might be required to reduce the carrying amount to equal estimated fair value. Assets held for sale are reported at the lower of the carrying amount or fair value less costs to dispose. Preferred Stock Preferred stock issued is non-cumulative and nonconvertible. The holders of the preferred stock are entitled to a non-cumulative dividend of 12% when and if declared. In liquidation, holders of preferred stock have preference to the extent of $1.00 per share plus dividends accrued but unpaid. No preferred stock dividends were declared or paid during the years ended December 31, 2020 and 2019. Revenue Recognition Our revenue is comprised of product, engineering services and repair services. All revenue is recognized when the Company satisfies its performance obligation(s) under the contract by transferring the promised product or service to our customer either when (or as) our customer obtains control of the product or service, with the majority of our revenue being recognized over time including goods produced under contract manufacturing agreements and services revenue. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer. A contract's transaction price is allocated to each distinct performance obligation. The majority of our contracts have a single performance obligation. Revenue is recorded net of returns, allowances and customer discounts. Our net sales for services were less than 10% of our total sales for all periods presented, and accordingly, are included in net sales in the Consolidated Statements of Operations and Comprehensive Loss. Sales, value add, and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs charged to our customers are included in net sales, while the corresponding shipping expenses are included in cost of goods sold. Product Warranties We provide limited warranty for the replacement or repair of defective product within a specified time period after the sale at no cost to our customers. We make no other guarantees or warranties, expressed or implied, of any nature whatsoever as to the goods including, without limitation, warranties to merchantability, fit for a particular purpose or non-infringement of patent or the like unless agreed upon in writing. We estimate the costs that may be incurred under our limited warranty and provide a reserve based on actual historical warranty claims coupled with an analysis of unfulfilled claims at the balance sheet date. Our warranty claim costs are not material given the nature of our products and services. Advertising Advertising costs are charged to operations as incurred. The total amount charged to expense was $42 and $101 for the years ended December 31, 2020 and 2019, respectively. Income Taxes We account for income taxes under the asset and liability method. Deferred income tax assets and liabilities are recognized annually for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We recognize interest and penalties accrued on any unrecognized tax benefits as a component on income tax expense. We 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 consolidated financial statements from such positions are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Management must also assess whether uncertain tax positions as filed could result in the recognition of a liability for possible interest and penalties if any. Our estimates are based on the information available to us at the time we prepare the income tax provisions. Our income tax returns are subject to audit by federal, state, and local governments, generally three years after the returns are filed. These returns could be subject to material adjustments or differing interpretations of the tax laws. Incentive Compensation We use a Black-Scholes option-pricing model to determine the grant date fair value of our incentive awards and recognize the expense on a straight-line basis over the vesting period. See Note 8 for additional information. Net Income (Loss) Per Common Share Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Dilutive net income (loss) per common share assumes the exercise and issuance of all potential common stock equivalents in computing the weighted-average number of common shares outstanding, unless their effect is antidilutive. There were no dilutive shares in the years ended 2020 or 2019 due to the net loss. Fair Value of Financial Instruments The carrying amounts of all financial instruments approximate their fair values. The carrying amounts for cash, accounts receivable, accounts payable, and accrued liabilities approximate fair value because of the short maturity of these instruments. Based on the borrowing rates currently available to us for bank loans with similar terms and average maturities, the carrying value of our long-term debt and line of credit approximates its fair value. 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. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value framework requires the categorization of assets and liabilities into one of three levels based on the assumptions (inputs) used in valuing the asset or liability. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. The three levels are defined as follows: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability, reflecting the reporting entity's own assumptions about the assumptions that market participants would use in pricing Our assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. We endeavor to use the best available information in measuring fair value. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. We utilized a Level 3 valuation of in our testing of goodwill as of October 1, 2020. See Note 4, Goodwill and Intangible Assets, for more detail. Enterprise-Wide Disclosures Our results of operations for the years ended December 31, 2020 and 2019 represent a single operating and reporting segment referred to as Contract Manufacturing within the EMS industry. Consolidated financial information is available that is evaluated regularly by the chief operating decision maker in assessing performance and allocating resources. Export sales from our domestic operations represent approximately 2.1% and 3.1% of consolidated net sales for the years ended December 31, 2020 and 2019, respectively. Net sales by our major EMS industry markets for the years ended December 31, 2020 and 2019 are as follows:
|  | 2020 |  |  | 2019 |
Medical |  | $ | 55,098 |  |  | $ | 62,612 |

Foreign Currency Transactions The functional currency for our Mexico subsidiary is the US dollar. Foreign exchange transaction gains and losses attributable to exchange rate movements related to transactions made in the local currency and on intercompany receivables and payables not deemed to be of a long-term investment nature are recorded in other income (expense). The functional currency for our China subsidiary is the Renminbi (“RMB”). Assets and liabilities of the China operation are translated from RMB into U.S. dollars at period-end rates, while income and expense are translated at the weighted-average exchange rates for the period. The related translation adjustments are reflected as a foreign currency translation adjustment in accumulated other comprehensive loss within shareholders' equity. The total foreign currency translation adjustment increased shareholders' equity by $220, from an accumulated foreign currency translation loss of $257 as of December 31, 2019 to an accumulated foreign currency translation loss of $37 as of December 31, 2020. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the Consolidated Statements of Operations. Net foreign currency transaction losses included in the determination of net earnings was $32 and $11 for the years ended December 31, 2020 and 2019, respectively. Liquidity and Capital Resources Our 2020 sales and shipment backlog were impacted by the ongoing COVID- 19 pandemic. Due to the inherent uncertainty of this evolving situation, we are unable at this time to predict the likely impact of the COVID- 19 pandemic on our future operations which has led to indicators of an inability to continue as a going concern. However, these indicators have been mitigated by our focus on reducing costs, minimizing capital expenditures, and managing working capital. In addition, we believe that cash provided by operations, funds available under the credit agreement with Bank of America, N.A. (BofA), funds available under a Promissory Note with BofA (“Promissory Note”) pursuant to the Paycheck Protection Program under the Coronavirus Aid, funds received from our sales leaseback transaction and cash on hand will be adequate to meet our liquidity needs, including working capital, capital expenditures, and debt payment obligations for at least the next 12 months from the financial statement release date. Recently Issued Accounting Standards In June 2016, the FASB issued ASU 2016 - 13, Measurement of Credit Losses on Financial Instruments. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The ASU also provides updated guidance regarding the impairment of available-for-sale debt securities and includes additional disclosure requirements. The new guidance is effective for public business entities that meet the definition of a Smaller Reporting Company as defined by the SEC for interim and annual periods beginning after December 15, 2022. Early adoption is permitted. We are currently evaluating the impact of this standard on our consolidated financial statements and related disclosures.
