CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
(UNAUDITED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements for the interim periods have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the financial information and footnotes required by GAAP for complete financial statements, although we believe the disclosures are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year or for any other interim period. In our opinion, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. In preparing these condensed consolidated financial statements, we have made our best estimates and judgments of certain amounts included in the condensed consolidated financial statements, giving due consideration to materiality. Changes in the estimates and assumptions used by us could have a significant impact on our financial results, since actual results could differ from those estimates.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Nortech Systems Incorporated and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

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 Condensed Consolidated Statements of Operations and Comprehensive Income (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.

Stock-Based Awards

Following is the status of all stock options as of September 30, 2021:

	Shares			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding - January 1, 2021		362,640		$	3.96
Granted		27,000			6.14
Exercised		(13,400	)		3.43
Cancelled		(10,340	)		3.42
Outstanding - September 30, 2021		365,900		$	4.15		7.25	$	2,688
Exercisable - September 30, 2021		180,500		$	3.75		6.56	$	1,398

In May 2017, the shareholders approved the 2017 Stock Incentive Plan which authorized the issuance of 400,000 shares. There were additional shares authorized in March 2020 totaling 50,000 and in May 2021 totaling 75,000. There were 27,000 and 11,300 stock options granted during the nine months ended September 30, 2021 and 2020, respectively.

Total compensation expense related to stock options for the three and nine months ended September 30, 2021 was $28 and $74, respectively. Total compensation expense related to stock options for the three and nine months ended September 30, 2020 was $36 and $111, respectively. As of September 30, 2021, there was $320 of unrecognized compensation which will vest over the next 3.12 years.

In November 2010, the Board of Directors adopted the Nortech Systems Incorporated Equity Appreciation Rights Plan (“2010 Plan”). The total number of Equity Appreciation Right Units (“Units”) that can be issued under the 2010 Plan shall not exceed an aggregate of 1,000,000 Units as amended and restated on March 11, 2015. During the nine months ended September 30, 2021 and 2020, there were no Units granted. We recognized $13 and $127 of compensation expense in the three and nine months ended September 30, 2021, respectively. Compensation expense was approximately $40 for both the three and nine months ended September 30, 2020. The current liability recorded for the Units at September 30, 2021 is $235.

Net Income per Common Share 

For the three and nine months ended September 30, 2021, stock options of 214,391 and 144,892, respectively, were included in the computation of diluted income per common share amount as their impact were dilutive. For the three and nine months ended September 30, 2020, stock options of 45,326 and 21,220, respectively, were included in the computation of diluted income per common share as their impact were dilutive.

Restricted Cash

Cash and cash equivalents classified as restricted cash on our condensed consolidated balance sheets are restricted as to withdrawal or use under the terms of certain contractual agreements. The September 30, 2021 balance included 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.

Accounts Receivable and Allowance for Doubtful Accounts

Credit is extended based upon an evaluation of the customer’s financial condition and, while collateral is not required, the Company periodically receives customer deposits. Credit terms are consistent with industry standards and practices. The amounts of trade accounts receivable have been reduced by an allowance for doubtful accounts of $361 at September 30, 2021 and $343 at December 31, 2020.

Employee Retention Credit (ERC) and Payroll Tax Deferral

We qualified for Employee Retention Credits on qualified wages paid in the first and second quarters of 2021 and filed for both credits as of the date of this filing. We recognize government grants for which there is a reasonable assurance of compliance with grant conditions and receipt of credits. During the three and nine months ended September 30, 2021, there was $5,209 related to Employee Retention Credits recognized as a reduction of the associated costs within cost of goods sold of $4,670, selling of $125, and general and administrative expenses of $414 on the consolidated statements of operations and within Employee Retention Credits Receivable on the condensed consolidated balance sheets.

The CARES Act allowed for the deferral of the employer portion of social security taxes incurred through the end of calendar 2020. As of September 30, 2021, there was $1,158 of social security tax payments deferred, of which 50% are required to be remitted by December 2021 and the remaining 50% by December 2022. The deferred amounts are recorded within accrued payroll and commissions on the condensed consolidated balance sheets.

Inventories, Net

Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. Costs include material, labor, and overhead required in the warehousing and production of our products. Inventory reserves are maintained for the estimated value of the inventories that may have a lower value than stated or quantities in excess of future production needs.

Inventories are as follows:

	September 30,			December 31,
	2021			2020
Raw Materials	$	19,673		$	14,865
Work in Process		1,683			969
Finished Goods		485			242
Reserves		(1,199	)		(2,159	)
Total	$	20,643		$	13,917

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.

Other Intangible Assets

Other intangible assets at September 30, 2021 and December 31, 2020 are as follows:

	Customer Relationships			Trade Names			Patents		Total
Balance at January 1, 2020	$	651		$	631		$	56	$	1,338
Additions		-			-			20		20
Amortization		(144	)		(41	)		-		(185	)
Balance at December 31, 2020	$	507		$	590		$	76	$	1,173
Additions		-			-			50		50
Amortization		(109	)		(30	)		-		(139	)
Abandonment Loss		-			(560	)		-		(560	)
Balance at September 31, 2021	$	398		$	-		$	126	$	524

In the three months ended September 30, 2021, we determined the fair value of the Devicix tradename was more likely than not be zero based on management’s best estimate and recognized a $560 loss on abandonment of intangible assets.

Intangible assets are amortized on a straight-line bases over their estimated useful lives. The weighted average remaining amortization period of our intangible assets is 3.0 years. Patents are not being amortized as they are in process and a patent has not yet been received.

Amortization expense for the three and nine months ended September 30, 2021 was $45 and $139, respectively.

9

Estimated future annual amortization expense (not including projects in process) related to these assets is approximately as follows (in thousands):

Year	Amount
Remainder of 2021	$	36
2022		145
2023		145
2024		72
Total	$	398

Reclassification

Certain reclassifications have been made to the prior year’s consolidated financial statements to enhance comparability with the current year’s financial statements. As a result, certain line items have been amended in the statement of operations. Comparative figures have been adjusted to conform to the current year’s presentation.

The items were reclassified as follows:

	Three Months Ended				Nine Months Ended
	September 30, 2020				September 30, 2020
	Previously Reported		After Reclassification		Previously Reported		After Reclassification
Cost of Goods Sold	$	24,717	$	24,400	$	73,171	$	72,336
General and Administrative Expenses		2,164		2,480		5,819		6,654

Accounting Pronouncements Issued But Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments,” which amends the guidance on the impairment of financial instruments. The amendments in this update removes the thresholds that entities apply to measure credit losses on financial instruments measured at amortized cost, such as loans, trade receivables, reinsurance recoverables, off-balance-sheet credit exposures, and held-to-maturity securities. Under current U.S. GAAP, entities generally recognize credit losses when it is probable that the loss has been incurred. The guidance removes all current recognition thresholds and introduces the new current expected credit loss (“CECL”) model which will require entities to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that an entity expects to collect over the instrument’s contractual life. The new CECL model is based upon expected losses rather than incurred losses. The amendments in this update are effective for periods beginning after December 15, 2022; early adoption is permitted. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform. ASU 2020-04 provides optional guidance for a limited period of time to ease potential accounting impact associated with transitioning away from reference rates that are expected to be discontinued, such as LIBOR. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in ASU 2020-04 can be adopted as of March 12, 2020 and are effective through December 31, 2022. We do not currently have any contracts that have been changed to a new reference rate, we will continue to evaluate our contracts and the effects of this standard on our condensed consolidated financial statements prior to adoption.

NOTE 2. CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and accounts receivable. With regard to cash, we maintain our excess cash balances in checking accounts at primarily two financial institutions, one in the United States and one in China. The account in the United States may at times exceed federally insured limits. Of the $1,443 in cash at September 30, 2021, approximately $378 and $5 was held at banks located in China and Mexico, respectively. We grant credit to customers in the normal course of business and do not require collateral on our accounts receivable.
 
We have certain customers whose revenue individually represented 10% or more of net sales, or whose accounts receivable balances individually represented 10% or more of total accounts receivable. For the three months ended September 30, 2021, two customers accounted for 36% of net sales. For the three months ended September 30, 2020, one customer accounted for 23% of net sales. At September 30, 2021 and 2020, one customer accounted for 26% and 23% of net sales, respectively 

At September 30, 2021, two customers represented approximately 36% of our total accounts receivable. At December 31, 2020, one customer represented approximately 20% of our total accounts receivable.

Export sales represented approximately 3% of net sales for the three months ended September 30, 2021 and 2020. Export sales represented 3% of net sales for the nine months ended September 30, 2021 and 2020. 

NOTE 3. REVENUE

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, as the promise to transfer products or services is not separately identifiable from other promises in the contract and, therefore, not distinct.
 
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services. As such, revenue is recorded net of returns, allowances and customer discounts. 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 are included in cost of goods sold.
 
The majority of our revenue is derived from the transfer of goods produced under contract manufacturing agreements which have no alternative use and we have an enforceable right to payment for our performance completed to date. Our performance obligations within our contract manufacturing agreements are generally satisfied over time as the goods are produced based on customer specifications and we have an enforceable right to payment for the goods produced. If these requirements are not met, the revenue is recognized at a point in time, generally upon shipment. Revenue under contract manufacturing agreements that was recognized over time accounted for approximately 82% and 80% of our revenue for the three and nine months ended September 30, 2021, respectively and for approximately 80% and 84% of our revenue for the three and nine months ended September 30, 2020, respectively. Revenues under these agreements are generally recognized over time using an input measure based upon the proportion of actual costs incurred.
 
Accounting for contract manufacturing agreements involves the use of various techniques to estimate total revenue and costs. We estimate profit on these agreements as the difference between total estimated revenue and expected costs to complete the performance obligation within the terms of the agreement and recognize the respective profit as the goods are produced. The estimates to determine the profit earned on the performance obligation are based on anticipated selling prices and historical cost of goods sold and represent our best judgement at the time. Changes in judgements on these above estimates could impact the timing and amount of revenue recognized with a resulting impact on the timing and amount of associated profit.
 
On occasion our customers provide materials to be used in the manufacturing process and the fair value of the materials is included in revenue as noncash consideration at the point in time when the manufacturing process commences along with the same corresponding amount recorded as cost of goods sold. The inclusion of noncash consideration has no impact on overall profitability.

NOTE 4. FINANCING ARRANGEMENTS

We have a credit agreement with Bank of America which was entered into on June 15, 2017, which was amended five separate occasions on December 29, 2017, August 13, 2019, November 12, 2019, August 27, 2020, and December 1, 2020 and provides for a line of credit arrangement of $16,000 that expires on June 15, 2022. The credit arrangement also has a $5,000 real estate term note outstanding with a maturity date of June 15, 2022. The line of credit is classified as current on the consolidated balance sheet as of September 30, 2021, however we expect to extend the agreement past June 15, 2022.
 
Under the Bank of America credit agreement, both the line of credit and real estate term notes are subject to variations in the LIBOR rate. Our line of credit bears interest at a weighted-average interest rate of 3.4% and 4.0% as of September 30, 2021 and December 31, 2020, respectively. We had borrowings on our line of credit of $6,009 and $3,328 outstanding as of September 30, 2021 and December 31, 2020, respectively. Borrowing on the real estate term note was $197 and $1,071 as of September 30, 2021 and December 31, 2020, respectively. Payment on the real estate term note is approximately $41 per month. There are no subjective acceleration clauses under the credit agreement that would accelerate the maturity of our outstanding borrowings. 

The line of credit and real estate term notes with Bank of America contain certain covenants which, among other things, require us to adhere to regular reporting requirements, abide by annual shareholder dividend limitations, maintain certain financial performance, and limit the amount of annual capital expenditures. The availability under our line is subject to borrowing base requirements, and advances are at the discretion of the lender. The line of credit is secured by substantially all of our assets.

The Bank of America Credit Agreement provides for, among other things, a Fixed Charge Coverage Ratio of not less than 1.0 to 1.0, for the twelve months ended December 31, 2020 and each Fiscal Quarter end thereafter subject only during a trigger period commencing when our availability under our line is less than $2,000 until availability is above that amount for 30 days due to amendment to our agreement dated in December of 2020. The Company met the covenants for the period ended September 30, 2021.

The availability under the line is subject to borrowing base requirements, and advances are at the discretion of the lender. At September 30, 2021, we had unused availability under our line of credit of $5,762, supported by our borrowing base. The line is secured by substantially all of our assets.

On April 15, 2020, we entered into the Promissory Note, which provides for an unsecured loan of $6,077 pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief, and Economic Security Act and applicable regulations (the “CARES Act”) of which funds were received on April 22, 2020. The Promissory Note has a term of 2 years with a 1% per annum interest rate. Payments are deferred for 10 months after the end of the Promissory Note covered period (which is defined as 24 weeks after the date of the loan) and we can apply for forgiveness of the Promissory Note after 60 days. Forgiveness of the Promissory Note will be determined in accordance with the provisions of the Cares Act and applicable regulations. Any principal and interest amounts outstanding after the determination of amounts forgiven will be repaid on a monthly basis. We applied for forgiveness of the Promissory Note in the third quarter of 2021. We continue to treat this Promissory Note as debt until forgiveness is granted, if forgiven.

NOTE 5. LEASES

We have operating leases for certain manufacturing sites, office space, and equipment. Most leases include the option to renew, with renewal terms that can extend the lease term from one to five years or more. Right-of-use lease assets and lease liabilities are recognized at the commencement date based on the present value of the remaining lease payments over the lease term which includes renewal periods we are reasonably certain to exercise. Our leases do not contain any material residual value guarantees or material restrictive covenants. At September 30, 2021, we do not have material lease commitments that have not commenced.

NOTE 6. INCOME TAXES

On a quarterly basis, we estimate what our effective tax rate will be for the full year and record a quarterly income tax provision based on the anticipated rate. As the year progresses, we refine our estimate based on the facts and circumstances, including discrete events, by each tax jurisdiction.

The effective tax rate for the three months ended September 30, 2021 was 26.0% compared to 23.7% for the three months ended September 30, 2020. The effective tax rate for the nine months ended September 30, 2021 was 22.8% compared to 24.3% for the nine months ended September 30, 2020. The primary drivers of the change in the effective tax rate is attributable to the PPP loan forgiveness being non-taxable and additional valuation allowance created from anticipated temporary differences. There are also discrete items related to an IRS exam and return to provision adjustments from the 2020 tax return. It is more likely than not an amount payable will be due at an estimated $44k for the IRS exam. A reserve has been set up for the anticipated adjustment. We recorded an income tax expense of $646k and $638k for the nine months ended September 30, 2021 and 2020, respectively.

NOTE 7. RESTRUCTURING CHARGES

During the first nine months of 2021, we recorded restructuring charges of $319 related to the consolidation of our production facilities and closure of our Merrifield, Minnesota facility. With the Merrifield closure, we shifted wire and cable assembly, system-level assembly and printed circuit board (PCB) manufacturing to Nortech’s other Minnesota locations. No amounts were accrued for the period ended September 30, 2021. We reduced our workforce by approximately 42 employees as a result of this facility closure.

The sale of the Merrifield facility was completed in July 2021. We recognized a gain on the sale of assets related to the restructure of $93 and $176 for the three and nine months ended September 30, 2021, respectively.

NOTE 8. RELATED PARTY TRANSACTIONS

During the nine months ended September 30, 2021, we did business with Printed Circuits, Inc. which was 90% owned by the Kunin family until late 2020. The Kunin family owns a majority of our stock. We had payments totaling $18 and $72 during the three and nine months ended September 30, 2021, respectively, and $0 and $28 for the three and nine months ended September 30, 2020, respectively, to Printed Circuits, Inc. The Company believes that these transactions are on terms comparable to those that the Company could reasonably expect in an arm's length transaction with an unrelated third party.

David Kunin, our Chairman, is a minority owner of Abilitech Medical, Inc. Mr. Kunin also was a consultant to Abilitech, which relationship ended on March 1, 2021. During 2020, Mr. Kunin earned $16 as a consultant to Abilitech. In the three months ended September 30, 2021 and 2020, Abilitech paid the Company $316 and $59, respectively, and in the nine months ended September 30, 2021 and 2020, paid the Company $1,056 and $668, respectively, for delivery of medical products. The Company believes that transactions with Abilitech are on terms comparable to those that the Company could reasonably expect in an arm's length transaction with an unrelated third party.

David Kunin, our Chairman, is a small minority owner (less than 10%) of Marpe Technologies, LTD an early-stage medical device company dedicated to the early detection of skin cancer through full body scanners.  Mr. Kunin is also a member of the Board of Directors of Marpe Technologies.  The Company worked with Marpe Technologies to apply for a grant from the Israel-United States Binational Industrial Research and Development Foundation, a legal entity created by Agreement between the Government of the State of Israel and the Government of the United States of America (“BIRD Foundation”).  The parties were successful in receiving approval for a $1,000 conditional grant.  The Company and Marpe Technologies will each receive $500 from the BIRD Foundation and, among other obligations under the grant, each is required to contribute $500 to match grant funds from the BIRD Foundation.  The Company will meet its obligation by providing certain services at cost or with respect to administrative services at no cost to Marpe Technologies. The total value of the contribution will not exceed $500.  The Company will receive a 10-year exclusive right to manufacture the products of Marpe Technologies. There can be no assurances that Marpe Technologies’ medical device will be commercially successful, that Marpe Technologies will be successful in raising additional funds to finance its operations or, if commercially successful, the Company will recoup the value of services provided to Marpe for which is not fully paid. The transactions between the Company and Marpe Technologies have been approved by the Audit Committee pursuant to the Company Related-Party Transactions Policy. As of September 30, 2021, we have received a $100 deposit, incurred expenses of $82 and recognized revenue of $78 from Marpe.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

We are a Maple Grove, Minnesota based full-service electronics manufacturing services (“EMS”) contract manufacturer of wire and cable assemblies, printed circuit board assemblies, higher-level assemblies and box builds for a wide range of industries. We provide value added engineering services and technical support including design, testing, prototyping and supply chain management to customers mainly in the medical, aerospace and defense, and industrial equipment markets. We maintain facilities in Bemidji, Blue Earth, Mankato, and Milaca, Minnesota; Monterrey, Mexico; and Suzhou, China. All of our facilities are certified to one or more of the ISO/AS standards, including 9001, AS9100 and 13485, with most having additional certifications based on the needs of the customers they serve.

Recent Developments

Global Pandemic
In March 2020, the World Health Organization recognized the outbreak of a novel coronavirus (“COVID-19”) as a pandemic. While the COVID-19 pandemic has had an impact on our operations, we have been able to continue to operate our manufacturing facilities and provide essential services to our customers. Additionally, in an effort to protect the health and safety of our employees and in compliance with state regulations, we have instituted a work-from-home policy for employees who can perform their job functions offsite, implemented social distancing requirements and other measures to allow manufacturing and other personnel essential to production to continue work within our manufacturing facilities.
 
The full extent to which COVID-19 will directly or indirectly impact our business, financial condition, and results of operations will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19, the actions taken to contain it or treat its impact and the economic impact on local, regional, national and international markets. The ultimate impact of COVID-19 depends on factors beyond our knowledge or control, including the duration and severity of the outbreak, as well as third-party actions taken to contain its spread and mitigate its public health effects. As a result, we are unable to estimate the extent to which COVID-19 will negatively impact our financial results or liquidity. 

We will continue to assess the current and potential impacts of the COVID-19 pandemic on our business, financial condition, and results of operations. We actively manage our cash and working capital to preserve adequate liquidity and ensure that our business can continue to operate during these uncertain times.

Facility Consolidation 
To further improve operational efficiencies and lower overhead costs, the Company approved on August 7, 2020, the closure of our Merrifield, Minnesota, production facility, shifting wire and cable assembly, system-level assembly and printed circuit board (PCB) manufacturing to Nortech’s other Minnesota locations. The Merrifield production facility consolidation was completed in the first quarter of 2021 and impacted approximately 42 employees, who were offered positions at other Nortech facilities in Minnesota. We entered into an agreement on February 23, 2021 with a third-party agent to sell our facility in Merrifield, MN and some related assets. The sale closed in the third quarter of 2021. 

Paycheck Protection Program (PPP) and Employee Retention Credit (ERC)
In the third quarter of 2021, we applied for forgiveness for the $6.1 million Promissory Note under the PPP. We will continue to treat this Promissory Note as debt until forgiveness is granted, any principal and interest amounts outstanding after the determination of amounts forgiven will be repaid on a monthly basis.

In addition, we applied for the ERC for qualified wages paid in the first and second quarters of 2021 and expect to receive approximately $5.2 million in fiscal 2021 or 2022. The ERC was recorded as a reduction of the associated payroll and benefit costs on the consolidated statements of operations for the three and nine months ended September 30, 2021 and as Employee Retention Credit Receivable on the consolidated balance sheet at September 30, 2021 (see Note 1.)

This backlog consists of firm purchase orders we expect to ship in the next 90 days.

90-day shipment backlog by our major EMS industry markets are as follows (in thousands):

	Shipment Backlog as of the Period Ended
	September 30,		June 30,		September 30,
	2021		2021		2020
Medical	$	19,666	$	18,879	$	11,483
Aerospace and Defense		8,568		5,981		6,764
Industrial		10,657		9,874		4,860
	$	38,891	$	34,734	$	23,108

Our 90-day backlog varies due to order size, manufacturing delays, contract terms and conditions and timing from customer delivery schedules and releases. These variables cause inconsistencies in comparing the backlog from one period to the next. Our total shipment backlog was $78.6 million at September 30, 2021 compared to $45.7 million at September 30, 2020.

Gross Profit

Gross profit as a percent of net sales for the three months ended September 30, 2021 and 2020 was 27.3% and 7.4%, respectively. Gross profit as a percentage of sales for the nine months ended September 30, 2021 and 2020 was 16.1% and 9.9%, respectively. The gross profit improvement relates primarily to the $4.7 million reduction in payroll and medical expenses related to the ERC and increased utilization as a result of the increase in sales.

Selling Expense

Selling expenses for the three months ended September 30, 2021 and 2020 was $0.4 million or 1.5% of sales and $0.6 million or 2.3% of sales, respectively. Selling expense for the nine months ended September 30, 2021 and 2020 was $1.7 million or 2.1% of sales and $1.9 million or 2.4% of sales, respectively. The decrease in selling expense for both the three and nine months ended September 30, 2021 compared to the same periods in the prior year relates primarily to the reduction in payroll and medical expenses of $0.1 million due to the ERC.

General and Administrative Expense

General and administrative expenses for the three months ended September 30, 2021 and 2020 were $2.0 million or 6.9% of sales and $2.5 million or 9.4% of sales, respectively. General and administrative expenses for the nine months ended September 30, 2021 and 2020 were $7.2 million or 8.9% of sales and $6.7 million or 8.3% of sales, respectively. The decrease in general and administrative expenses for the three months ended September 30, 2021 compared to the same period of 2020 relates primarily to the reduction in payroll and medical expenses of $0.4 million related to the ERC. The increase in general and administrative expenses for the nine months ended September 30, 2021 compared to the same period of 2020 relates primarily to an increase in professional service fees.

Research and Development Expense

Research and development expenses for the three months ended September 30, 2021 were $0.1 million or 0.5% of sales. Research and development expenses for the nine months ended September 30, 2021 were $0.3 million or 0.4% of sales. There were minimal to no research and development expenses for the three and nine months ended September 30, 2020.

Restructuring Charges

Restructuring charges for the three months ended September 30, 2021 were approximately $23 thousand or 0.1% of sales. Restructuring charges for the nine months ended September 30, 2021 was $0.3 million or 0.4% of sales. There were no restructuring charges for the three and nine months ended September 30, 2020. The restructuring charges are due to the closure of the Merrifield facility.

20

Loss on Abandonment of Intangible Asset

Abandonment charges for the three and nine months ended September 30, 2021 were approximately $0.6 million. There were no abandonment charges for the three and nine months ended September 30, 2020. The charges relate to the abandonment of the Devicix tradename.

Income Taxes

On a quarterly basis, we estimate what our effective tax rate will be for the full fiscal year and record a quarterly income tax provision based on the anticipated rate. As the year progresses, we refine our estimate based on the facts and circumstances, including discrete events, by each tax jurisdiction. Our effective tax rate for the three and nine months ended September 30, 2021 was 26.0% and 22.8%, respectively, and the rate for the three and nine months ended September 30, 2020 was 22.8% and 24.3%, respectively.

Net Income

Net income for the three months and net loss for the nine months ended September 30, 2021 was $3.6 million and $2.2 million, respectively. Net income for the three and nine months ended September 30, 2020 was $2.0 million. Net income for the three and nine months ended September 30, 2021 was affected by the reduction in payroll and benefit expense for the ERC, while the three and nine months ended September 30, 2020 included a $3.8 million gain on sale of assets.

Liquidity and Capital Resources

Our 2021 sales were impacted by the ongoing COVID-19 pandemic and the related supply chain and workforce shortages. 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 and minimizing capital expenditures. In addition, we believe that cash provided by operations, funds available under the credit agreement with Bank of America, N.A. (BofA), funds expected to be received for the ERC and cash on hand will be adequate to meet our liquidity needs, including working capital, capital expenditures, and debt payment obligations.

Net cash used by operating activities for the nine months ended September 30, 2021 was $2.9 million. Increases in working capital due to the higher sales and backlog drove the use of cash by operating activities, primarily in increased inventory of $5.8 million.

We have a credit agreement with Bank of America (BofA) which was entered into on June 15, 2017 and amended on December 29, 2017 and provides for a line of credit arrangement of $16.0 million that expires on June 15, 2022. The credit arrangement also has a $5.0 million real estate term note outstanding with a maturity date of June 15, 2022. We expect to extend the agreement past June 15, 2022.

Both the line of credit and real estate term notes are subject to fluctuations in the LIBOR rates. The line of credit and real estate term notes with BofA contain certain covenants which, among other things, require us to adhere to regular reporting requirements, abide by annual shareholder dividend limitations, maintain certain financial performance, and limit the amount of annual capital expenditures. The availability under our line is subject to borrowing base requirements, and advances are at the discretion of the lender. The line of credit is secured by substantially all of our assets. 

The Bank of America Credit Agreement provides for, among other things, a Fixed Charge Coverage Ratio of not less than 1.0 to 1.0, for the twelve months ending December 31, 2020 and each Fiscal Quarter end thereafter subject only during a trigger period commencing when our availability under our line is less than $2,000 until availability is above that amount for 30 days due to amendment to our agreement dated in December of 2020. The Company met the covenants for the period ended September 30, 2021.

The availability under the line is subject to borrowing base requirements, and advances are at the discretion of the lender. At September 30, 2021, we had outstanding advances of $6.0 million and we had unused availability under our line of credit of $5.8 million, supported by our borrowing base. We believe our financing arrangements and cash flows to be provided by operations will be sufficient to satisfy our future working capital needs.

On April 15, 2020, we entered into a Promissory Note with Bank of America, N.A. (the “Promissory Note”), which provides for an unsecured loan of $6.1 million pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act and applicable regulations (the “CARES Act”) of which; funds were received on April 22, 2020. The Promissory Note has a term of 2 years with a 1% per annum interest rate. Payments are deferred for 6 months from the date of the Promissory Note and we can apply for forgiveness of the Promissory Note after 60 days. Forgiveness of the Promissory Note will be determined in accordance with the provisions of the Cares Act and applicable regulations. We applied for forgiveness in the third quarter of 2021, any principal and interest amounts outstanding after the determination of amounts forgiven will be repaid on a monthly basis.

Off-Balance Sheet Arrangements

We have not engaged in any off-balance sheet activities as defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies and Estimates

Our significant accounting policies and estimates are summarized in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2020. Some of our accounting policies require us to exercise significant judgment in selecting the appropriate assumptions for calculating financial estimates. Such judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, known trends in our industry, terms of existing contracts and other information from outside sources, as appropriate. Actual results could differ from these estimates.

Forward-Looking Statements

Those statements in the foregoing report that are not historical facts are forward-looking statements made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.

♦	Volatility in the marketplace which may affect market supply, demand of our products or currency exchange rates;
♦	Supply chain disruption and unreliability due to COVID-19;
♦	Lack of supply of sufficient human resources to produce our products;
♦	Increased competition from within the EMS industry or the decision of OEMs to cease or limit outsourcing;
♦	Changes in the reliability and efficiency of our operating facilities or those of third parties;
♦	Increases in certain raw material costs such as copper and oil;

♦	Disruption of global or local information management systems due to natural disaster or cyber-security incident;
♦	Outbreaks of epidemic, pandemic, or contagious diseases, such as the recent novel coronavirus that affect our operations, our customers' operations or our suppliers' operations.

The factors identified above are believed to be important factors (but not necessarily all of the important factors) that could cause actual results to differ materially from those expressed in any forward-looking statement made by us. Discussion of these factors is also incorporated in Part I, Item 1A, “Risk Factors,” and should be considered an integral part of Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Unpredictable or unknown factors not discussed herein could also have material adverse effects on forward-looking statements. All forward-looking statements included in this Form 10-Q are expressly qualified in their entirety by the forgoing cautionary statements. We undertake no obligations to update publicly any forward-looking statement (or its associated cautionary language) whether as a result of new information or future events.

Evaluation of Disclosure Controls and Procedures

In accordance with Rule 13a-15(b) of the Securities Exchange Act of 1934 (the “Exchange Act”), as of the end of the period covered by this Quarterly Report on Form 10-Q, our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act).

Notes to Financial Statements

Basis of Presentation and Significant Accounting Policies [Text Block]

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements for the interim periods have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the financial information and footnotes required by GAAP for complete financial statements, although we believe the disclosures are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year or for any other interim period. In our opinion, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. In preparing these condensed consolidated financial statements, we have made our best estimates and judgments of certain amounts included in the condensed consolidated financial statements, giving due consideration to materiality. Changes in the estimates and assumptions used by us could have a significant impact on our financial results, since actual results could differ from those estimates.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Nortech Systems Incorporated and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

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 Condensed Consolidated Statements of Operations and Comprehensive Income (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.

Stock-Based Awards

Following is the status of all stock options as of September 30, 2021:

	Shares			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding - January 1, 2021		362,640		$	3.96
Granted		27,000			6.14
Exercised		(13,400	)		3.43
Cancelled		(10,340	)		3.42
Outstanding - September 30, 2021		365,900		$	4.15		7.25	$	2,688
Exercisable - September 30, 2021		180,500		$	3.75		6.56	$	1,398

In May 2017, the shareholders approved the 2017 Stock Incentive Plan which authorized the issuance of 400,000 shares. There were additional shares authorized in March 2020 totaling 50,000 and in May 2021 totaling 75,000. There were 27,000 and 11,300 stock options granted during the nine months ended September 30, 2021 and 2020, respectively.

Total compensation expense related to stock options for the three and nine months ended September 30, 2021 was $28 and $74, respectively. Total compensation expense related to stock options for the three and nine months ended September 30, 2020 was $36 and $111, respectively. As of September 30, 2021, there was $320 of unrecognized compensation which will vest over the next 3.12 years.

In November 2010, the Board of Directors adopted the Nortech Systems Incorporated Equity Appreciation Rights Plan (“2010 Plan”). The total number of Equity Appreciation Right Units (“Units”) that can be issued under the 2010 Plan shall not exceed an aggregate of 1,000,000 Units as amended and restated on March 11, 2015. During the nine months ended September 30, 2021 and 2020, there were no Units granted. We recognized $13 and $127 of compensation expense in the three and nine months ended September 30, 2021, respectively. Compensation expense was approximately $40 for both the three and nine months ended September 30, 2020. The current liability recorded for the Units at September 30, 2021 is $235.

Net Income per Common Share 

For the three and nine months ended September 30, 2021, stock options of 214,391 and 144,892, respectively, were included in the computation of diluted income per common share amount as their impact were dilutive. For the three and nine months ended September 30, 2020, stock options of 45,326 and 21,220, respectively, were included in the computation of diluted income per common share as their impact were dilutive.

Restricted Cash

Cash and cash equivalents classified as restricted cash on our condensed consolidated balance sheets are restricted as to withdrawal or use under the terms of certain contractual agreements. The September 30, 2021 balance included 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.

Accounts Receivable and Allowance for Doubtful Accounts

Credit is extended based upon an evaluation of the customer’s financial condition and, while collateral is not required, the Company periodically receives customer deposits. Credit terms are consistent with industry standards and practices. The amounts of trade accounts receivable have been reduced by an allowance for doubtful accounts of $361 at September 30, 2021 and $343 at December 31, 2020.

Employee Retention Credit (ERC) and Payroll Tax Deferral

We qualified for Employee Retention Credits on qualified wages paid in the first and second quarters of 2021 and filed for both credits as of the date of this filing. We recognize government grants for which there is a reasonable assurance of compliance with grant conditions and receipt of credits. During the three and nine months ended September 30, 2021, there was $5,209 related to Employee Retention Credits recognized as a reduction of the associated costs within cost of goods sold of $4,670, selling of $125, and general and administrative expenses of $414 on the consolidated statements of operations and within Employee Retention Credits Receivable on the condensed consolidated balance sheets.

The CARES Act allowed for the deferral of the employer portion of social security taxes incurred through the end of calendar 2020. As of September 30, 2021, there was $1,158 of social security tax payments deferred, of which 50% are required to be remitted by December 2021 and the remaining 50% by December 2022. The deferred amounts are recorded within accrued payroll and commissions on the condensed consolidated balance sheets.

Inventories, Net

Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. Costs include material, labor, and overhead required in the warehousing and production of our products. Inventory reserves are maintained for the estimated value of the inventories that may have a lower value than stated or quantities in excess of future production needs.

Inventories are as follows:

	September 30,			December 31,
	2021			2020
Raw Materials	$	19,673		$	14,865
Work in Process		1,683			969
Finished Goods		485			242
Reserves		(1,199	)		(2,159	)
Total	$	20,643		$	13,917

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.

Other Intangible Assets

Other intangible assets at September 30, 2021 and December 31, 2020 are as follows:

	Customer Relationships			Trade Names			Patents		Total
Balance at January 1, 2020	$	651		$	631		$	56	$	1,338
Additions		-			-			20		20
Amortization		(144	)		(41	)		-		(185	)
Balance at December 31, 2020	$	507		$	590		$	76	$	1,173
Additions		-			-			50		50
Amortization		(109	)		(30	)		-		(139	)
Abandonment Loss		-			(560	)		-		(560	)
Balance at September 31, 2021	$	398		$	-		$	126	$	524

In the three months ended September 30, 2021, we determined the fair value of the Devicix tradename was more likely than not be zero based on management’s best estimate and recognized a $560 loss on abandonment of intangible assets.

Intangible assets are amortized on a straight-line bases over their estimated useful lives. The weighted average remaining amortization period of our intangible assets is 3.0 years. Patents are not being amortized as they are in process and a patent has not yet been received.

Amortization expense for the three and nine months ended September 30, 2021 was $45 and $139, respectively.

Estimated future annual amortization expense (not including projects in process) related to these assets is approximately as follows (in thousands):

Year	Amount
Remainder of 2021	$	36
2022		145
2023		145
2024		72
Total	$	398

Reclassification

Certain reclassifications have been made to the prior year’s consolidated financial statements to enhance comparability with the current year’s financial statements. As a result, certain line items have been amended in the statement of operations. Comparative figures have been adjusted to conform to the current year’s presentation.

The items were reclassified as follows:

	Three Months Ended				Nine Months Ended
	September 30, 2020				September 30, 2020
	Previously Reported		After Reclassification		Previously Reported		After Reclassification
Cost of Goods Sold	$	24,717	$	24,400	$	73,171	$	72,336
General and Administrative Expenses		2,164		2,480		5,819		6,654

Accounting Pronouncements Issued But Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments,” which amends the guidance on the impairment of financial instruments. The amendments in this update removes the thresholds that entities apply to measure credit losses on financial instruments measured at amortized cost, such as loans, trade receivables, reinsurance recoverables, off-balance-sheet credit exposures, and held-to-maturity securities. Under current U.S. GAAP, entities generally recognize credit losses when it is probable that the loss has been incurred. The guidance removes all current recognition thresholds and introduces the new current expected credit loss (“CECL”) model which will require entities to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that an entity expects to collect over the instrument’s contractual life. The new CECL model is based upon expected losses rather than incurred losses. The amendments in this update are effective for periods beginning after December 15, 2022; early adoption is permitted. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform. ASU 2020-04 provides optional guidance for a limited period of time to ease potential accounting impact associated with transitioning away from reference rates that are expected to be discontinued, such as LIBOR. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in ASU 2020-04 can be adopted as of March 12, 2020 and are effective through December 31, 2022. We do not currently have any contracts that have been changed to a new reference rate, we will continue to evaluate our contracts and the effects of this standard on our condensed consolidated financial statements prior to adoption.

Notes to Financial Statements

Concentration Risk Disclosure [Text Block]

NOTE 2. CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and accounts receivable. With regard to cash, we maintain our excess cash balances in checking accounts at primarily two financial institutions, one in the United States and one in China. The account in the United States may at times exceed federally insured limits. Of the $1,443 in cash at September 30, 2021, approximately $378 and $5 was held at banks located in China and Mexico, respectively. We grant credit to customers in the normal course of business and do not require collateral on our accounts receivable.
 
We have certain customers whose revenue individually represented 10% or more of net sales, or whose accounts receivable balances individually represented 10% or more of total accounts receivable. For the three months ended September 30, 2021, two customers accounted for 36% of net sales. For the three months ended September 30, 2020, one customer accounted for 23% of net sales. At September 30, 2021 and 2020, one customer accounted for 26% and 23% of net sales, respectively 

At September 30, 2021, two customers represented approximately 36% of our total accounts receivable. At December 31, 2020, one customer represented approximately 20% of our total accounts receivable.

Export sales represented approximately 3% of net sales for the three months ended September 30, 2021 and 2020. Export sales represented 3% of net sales for the nine months ended September 30, 2021 and 2020.

Revenue from Contract with Customer [Text Block]

NOTE 3. REVENUE

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, as the promise to transfer products or services is not separately identifiable from other promises in the contract and, therefore, not distinct.
 
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services. As such, revenue is recorded net of returns, allowances and customer discounts. 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 are included in cost of goods sold.
 
The majority of our revenue is derived from the transfer of goods produced under contract manufacturing agreements which have no alternative use and we have an enforceable right to payment for our performance completed to date. Our performance obligations within our contract manufacturing agreements are generally satisfied over time as the goods are produced based on customer specifications and we have an enforceable right to payment for the goods produced. If these requirements are not met, the revenue is recognized at a point in time, generally upon shipment. Revenue under contract manufacturing agreements that was recognized over time accounted for approximately 82% and 80% of our revenue for the three and nine months ended September 30, 2021, respectively and for approximately 80% and 84% of our revenue for the three and nine months ended September 30, 2020, respectively. Revenues under these agreements are generally recognized over time using an input measure based upon the proportion of actual costs incurred.
 
Accounting for contract manufacturing agreements involves the use of various techniques to estimate total revenue and costs. We estimate profit on these agreements as the difference between total estimated revenue and expected costs to complete the performance obligation within the terms of the agreement and recognize the respective profit as the goods are produced. The estimates to determine the profit earned on the performance obligation are based on anticipated selling prices and historical cost of goods sold and represent our best judgement at the time. Changes in judgements on these above estimates could impact the timing and amount of revenue recognized with a resulting impact on the timing and amount of associated profit.
 
On occasion our customers provide materials to be used in the manufacturing process and the fair value of the materials is included in revenue as noncash consideration at the point in time when the manufacturing process commences along with the same corresponding amount recorded as cost of goods sold. The inclusion of noncash consideration has no impact on overall profitability.

Contract Assets

Contract assets, recorded as such in the Condensed Consolidated Balance Sheet, consist of unbilled amounts related to revenue recognized over time. Significant changes in the contract assets balance during the nine months ended September 30, 2021 was as follows (in thousands):

Nine Months Ended September 30, 2021
Outstanding at January 1, 2021	$	5,899
Increase (decrease) attributed to:
Transferred to receivables from contract assets recognized		(5,140	)
Product transferred over time		7,387
Outstanding at September 30, 2021	$	8,145

We expect substantially all the remaining performance obligations for the contract assets recorded as of September 30, 2021, to be transferred to receivables within 90 days, with any remaining amounts to be transferred within 180 days. We bill our customers upon shipment with payment terms of up to 120 days.

The following tables summarize our net sales by market for the three and nine months ended September 30, 2021 and 2020 (in thousands):

NOTE 4. FINANCING ARRANGEMENTS

We have a credit agreement with Bank of America which was entered into on June 15, 2017, which was amended five separate occasions on December 29, 2017, August 13, 2019, November 12, 2019, August 27, 2020, and December 1, 2020 and provides for a line of credit arrangement of $16,000 that expires on June 15, 2022. The credit arrangement also has a $5,000 real estate term note outstanding with a maturity date of June 15, 2022. The line of credit is classified as current on the consolidated balance sheet as of September 30, 2021, however we expect to extend the agreement past June 15, 2022.
 
Under the Bank of America credit agreement, both the line of credit and real estate term notes are subject to variations in the LIBOR rate. Our line of credit bears interest at a weighted-average interest rate of 3.4% and 4.0% as of September 30, 2021 and December 31, 2020, respectively. We had borrowings on our line of credit of $6,009 and $3,328 outstanding as of September 30, 2021 and December 31, 2020, respectively. Borrowing on the real estate term note was $197 and $1,071 as of September 30, 2021 and December 31, 2020, respectively. Payment on the real estate term note is approximately $41 per month. There are no subjective acceleration clauses under the credit agreement that would accelerate the maturity of our outstanding borrowings. 

The line of credit and real estate term notes with Bank of America contain certain covenants which, among other things, require us to adhere to regular reporting requirements, abide by annual shareholder dividend limitations, maintain certain financial performance, and limit the amount of annual capital expenditures. The availability under our line is subject to borrowing base requirements, and advances are at the discretion of the lender. The line of credit is secured by substantially all of our assets.

The Bank of America Credit Agreement provides for, among other things, a Fixed Charge Coverage Ratio of not less than 1.0 to 1.0, for the twelve months ended December 31, 2020 and each Fiscal Quarter end thereafter subject only during a trigger period commencing when our availability under our line is less than $2,000 until availability is above that amount for 30 days due to amendment to our agreement dated in December of 2020. The Company met the covenants for the period ended September 30, 2021.

The availability under the line is subject to borrowing base requirements, and advances are at the discretion of the lender. At September 30, 2021, we had unused availability under our line of credit of $5,762, supported by our borrowing base. The line is secured by substantially all of our assets.

On April 15, 2020, we entered into the Promissory Note, which provides for an unsecured loan of $6,077 pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief, and Economic Security Act and applicable regulations (the “CARES Act”) of which funds were received on April 22, 2020. The Promissory Note has a term of 2 years with a 1% per annum interest rate. Payments are deferred for 10 months after the end of the Promissory Note covered period (which is defined as 24 weeks after the date of the loan) and we can apply for forgiveness of the Promissory Note after 60 days. Forgiveness of the Promissory Note will be determined in accordance with the provisions of the Cares Act and applicable regulations. Any principal and interest amounts outstanding after the determination of amounts forgiven will be repaid on a monthly basis. We applied for forgiveness of the Promissory Note in the third quarter of 2021. We continue to treat this Promissory Note as debt until forgiveness is granted, if forgiven.

NOTE 6. INCOME TAXES

On a quarterly basis, we estimate what our effective tax rate will be for the full year and record a quarterly income tax provision based on the anticipated rate. As the year progresses, we refine our estimate based on the facts and circumstances, including discrete events, by each tax jurisdiction.

The effective tax rate for the three months ended September 30, 2021 was 26.0% compared to 23.7% for the three months ended September 30, 2020. The effective tax rate for the nine months ended September 30, 2021 was 22.8% compared to 24.3% for the nine months ended September 30, 2020. The primary drivers of the change in the effective tax rate is attributable to the PPP loan forgiveness being non-taxable and additional valuation allowance created from anticipated temporary differences. There are also discrete items related to an IRS exam and return to provision adjustments from the 2020 tax return. It is more likely than not an amount payable will be due at an estimated $44k for the IRS exam. A reserve has been set up for the anticipated adjustment. We recorded an income tax expense of $646k and $638k for the nine months ended September 30, 2021 and 2020, respectively.

NOTE 7. RESTRUCTURING CHARGES

During the first nine months of 2021, we recorded restructuring charges of $319 related to the consolidation of our production facilities and closure of our Merrifield, Minnesota facility. With the Merrifield closure, we shifted wire and cable assembly, system-level assembly and printed circuit board (PCB) manufacturing to Nortech’s other Minnesota locations. No amounts were accrued for the period ended September 30, 2021. We reduced our workforce by approximately 42 employees as a result of this facility closure.

NOTE 8. RELATED PARTY TRANSACTIONS

During the nine months ended September 30, 2021, we did business with Printed Circuits, Inc. which was 90% owned by the Kunin family until late 2020. The Kunin family owns a majority of our stock. We had payments totaling $18 and $72 during the three and nine months ended September 30, 2021, respectively, and $0 and $28 for the three and nine months ended September 30, 2020, respectively, to Printed Circuits, Inc. The Company believes that these transactions are on terms comparable to those that the Company could reasonably expect in an arm's length transaction with an unrelated third party.

David Kunin, our Chairman, is a minority owner of Abilitech Medical, Inc. Mr. Kunin also was a consultant to Abilitech, which relationship ended on March 1, 2021. During 2020, Mr. Kunin earned $16 as a consultant to Abilitech. In the three months ended September 30, 2021 and 2020, Abilitech paid the Company $316 and $59, respectively, and in the nine months ended September 30, 2021 and 2020, paid the Company $1,056 and $668, respectively, for delivery of medical products. The Company believes that transactions with Abilitech are on terms comparable to those that the Company could reasonably expect in an arm's length transaction with an unrelated third party.

David Kunin, our Chairman, is a small minority owner (less than 10%) of Marpe Technologies, LTD an early-stage medical device company dedicated to the early detection of skin cancer through full body scanners.  Mr. Kunin is also a member of the Board of Directors of Marpe Technologies.  The Company worked with Marpe Technologies to apply for a grant from the Israel-United States Binational Industrial Research and Development Foundation, a legal entity created by Agreement between the Government of the State of Israel and the Government of the United States of America (“BIRD Foundation”).  The parties were successful in receiving approval for a $1,000 conditional grant.  The Company and Marpe Technologies will each receive $500 from the BIRD Foundation and, among other obligations under the grant, each is required to contribute $500 to match grant funds from the BIRD Foundation.  The Company will meet its obligation by providing certain services at cost or with respect to administrative services at no cost to Marpe Technologies. The total value of the contribution will not exceed $500.  The Company will receive a 10-year exclusive right to manufacture the products of Marpe Technologies. There can be no assurances that Marpe Technologies’ medical device will be commercially successful, that Marpe Technologies will be successful in raising additional funds to finance its operations or, if commercially successful, the Company will recoup the value of services provided to Marpe for which is not fully paid. The transactions between the Company and Marpe Technologies have been approved by the Audit Committee pursuant to the Company Related-Party Transactions Policy. As of September 30, 2021, we have received a $100 deposit, incurred expenses of $82 and recognized revenue of $78 from Marpe.

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements for the interim periods have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the financial information and footnotes required by GAAP for complete financial statements, although we believe the disclosures are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year or for any other interim period. In our opinion, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. In preparing these condensed consolidated financial statements, we have made our best estimates and judgments of certain amounts included in the condensed consolidated financial statements, giving due consideration to materiality. Changes in the estimates and assumptions used by us could have a significant impact on our financial results, since actual results could differ from those estimates.

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Nortech Systems Incorporated and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Revenue [Policy Text Block]

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 Condensed Consolidated Statements of Operations and Comprehensive Income (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.

New Accounting Pronouncements, Policy [Policy Text Block]

Accounting Pronouncements Issued But Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments,” which amends the guidance on the impairment of financial instruments. The amendments in this update removes the thresholds that entities apply to measure credit losses on financial instruments measured at amortized cost, such as loans, trade receivables, reinsurance recoverables, off-balance-sheet credit exposures, and held-to-maturity securities. Under current U.S. GAAP, entities generally recognize credit losses when it is probable that the loss has been incurred. The guidance removes all current recognition thresholds and introduces the new current expected credit loss (“CECL”) model which will require entities to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that an entity expects to collect over the instrument’s contractual life. The new CECL model is based upon expected losses rather than incurred losses. The amendments in this update are effective for periods beginning after December 15, 2022; early adoption is permitted. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform. ASU 2020-04 provides optional guidance for a limited period of time to ease potential accounting impact associated with transitioning away from reference rates that are expected to be discontinued, such as LIBOR. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in ASU 2020-04 can be adopted as of March 12, 2020 and are effective through December 31, 2022. We do not currently have any contracts that have been changed to a new reference rate, we will continue to evaluate our contracts and the effects of this standard on our condensed consolidated financial statements prior to adoption.
