Note 1 – The Company and its Significant Accounting Policies

Description of Business

Interlink Electronics, Inc. (“we,” “us,” “our,” “Interlink” or the “Company”) designs, develops, manufactures and sells a range of force-sensing technologies that incorporate our proprietary materials technology, firmware and software into a portfolio of standard sensor based products and custom sensor system solutions. These include sensor components, subassemblies, modules and products that support effective, efficient cursor control and novel three-dimensional user inputs. Our Human Machine Interface (“HMI”) technology platforms are deployed in a wide range of markets including consumer electronics, automotive, industrial, and medical.

Interlink serves our world-wide customer base from our corporate headquarters in Irvine, California (Orange County) and from our facility in Camarillo, California (Ventura County). We have established a Global Product Development and Materials Science Center in our Camarillo footprint. This facility has a state-of-the-art printed electronics development laboratory as well as materials science lab. Our engineering team is based in this center where we work with our U.S. and global customers on developing, engineering, prototyping and implementing our advanced HMI solutions. We also maintain a small embedded software and Internet-of-Things (“IoT”) application development center in Singapore. We manufacture all our products in our printed electronics manufacturing facility in Shenzhen, China. In addition, we maintain a global distribution and logistics center in Hong Kong, a technical sales office in Japan, and several manufacturer representatives and distributors in strategic locations in our key markets, all of which allows us to support our global customer base. We sell our products in a wide range of markets, including consumer electronics, automotive, industrial and medical. Our customers are some of the world’s largest companies and most recognizable brands.

We were incorporated in California in 1985. In 1996, we re-incorporated into a Delaware corporation and, in 2012, we again changed our domicile from Delaware to Nevada by completing a merger with a newly formed Nevada corporation named Interlink Electronics, Inc.

Our principal executive office is located at 1 Jenner, Suite 200, Irvine, California 92618 and our telephone number is (805) 484-8855. Our website address is www.interlinkelectronics.com. Interlink makes available its annual financial statements, quarterly financial statements, and other significant reports and amendments to such reports, free of charge, on its website as soon as reasonably practicable after such reports are prepared.

Fiscal Year

Our fiscal year is the calendar year reporting cycle beginning January 1 and ending December 31.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intra-entity transactions and balances have been eliminated in consolidation.

The accompanying unaudited interim consolidated financial statements for the Company and its subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial reporting. Accordingly, certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted. In the opinion of management, the accompanying unaudited interim consolidated financial statements reflect all adjustments (consisting of only normal recurring adjustments and the elimination of intra-entity accounts) considered necessary for a fair presentation of all periods presented. The results of the Company’s operations for any interim periods are not necessarily indicative of the results of operations for any other interim period or for a full fiscal year. These unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes included in our Annual Report on Form 10-K, which was filed the Securities and Exchange Commission on March 17, 2021.

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Management regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, warranty reserves, inventory valuation reserves, stock-based compensation, purchased intangible asset valuations and useful lives, asset retirement obligations, and deferred income tax asset valuation allowances. These estimates and assumptions are based on current facts, historical experience and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. The actual results we experience may differ materially and adversely from our original estimates. To the extent there are material differences between the estimates and the actual results, our future results of operations will be affected.

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), when a customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services.

To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. The five-step model is applied to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services transferred to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize revenue in the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Delivery occurs when goods are shipped and title and risk of loss transfer to the customer, in accordance with the terms specified in the arrangement with the customer. Revenue recognition is deferred until the earnings process is complete.

We (i) input orders based upon receipt of a customer purchase order, (ii) confirm pricing through the customer purchase order record, (iii) validate creditworthiness through past payment history, credit agency reports and other financial data, and (iv) recognize revenue upon shipment of goods or when risk of loss and title transfer to the buyer. All customers have warranty rights, and some customers also have explicit or implicit rights of return. We establish reserves for potential customer returns or warranty repairs based on historical experience and other factors that enable us to reasonably estimate the obligation.

A portion of our product sales is made through distributors under agreements allowing for right of return. Our past history with these sell-through right of return provisions allow us to reasonably estimate the amount of inventory that could be returned pursuant to these agreements, and revenue is recognized accordingly.

We recognize revenue for non-recurring engineering or non-recurring tooling fees when there is persuasive evidence of an arrangement, performance obligations are identified, fees are fixed or determinable, delivery has occurred, and collectability is reasonably assured.

Warranty

We establish reserves for future product warranty costs that are expected to be incurred pursuant to specific warranty provisions with our customers. We generally warrant our products against defects for one year from date of shipment, with certain exceptions in which the warranty period can extend to more than one year based on contractual agreements. A warranty reserve is recorded against revenues when products are shipped. At each reporting period, we adjust our reserve for warranty claims based on our actual warranty claims experience as a percentage of net revenue for the preceding 12 months and also consider the effect of known operations issues that may have an impact that differs from historical trends. Historically, our warranty returns have not been material.

Shipping and Handling Fees and Costs

Amounts billed to customers for shipping and handling fees are presented in revenues. Costs incurred for shipping and handling are included in cost of revenues.

Engineering, Research and Development Costs

Engineering, research and development (“R&D”) costs are expensed when incurred. R&D expenses consist primarily of compensation expenses for employees engaged in research, design and development activities. R&D expenses also include depreciation and amortization, and overhead, including facilities expenses.

Marketing and Advertising Costs

All of the costs related to marketing and advertising our products are expensed as incurred or at the time the marketing or advertising takes place.

Stock-Based Compensation

Under the terms of our 2016 Omnibus Incentive Plan (the “2016 Plan”), directors, officers and key employees could be granted restricted stock units and stock awards, as well as non-qualified or incentive stock options, at the discretion of the Compensation Committee of the Board of Directors.

All stock-based payments to directors and employees, including grants of stock options and stock purchase rights, are recognized in the financial statements based on their respective grant date (measurement date) fair values. We calculate the compensation cost of full-value awards such as restricted stock units and stock awards based on the market value of the underlying stock at the date of the grant. The fair value of stock option awards is estimated at the date of grant using the Black-Scholes option pricing model; however, the value calculated using an option pricing model may not be indicative of the fair value observed in a willing buyer/willing seller market transaction, or actually realized by the employee upon exercise. Expected volatility used to estimate the fair value of options granted is based on the historical volatility of our common stock. The risk-free interest rate is based on the United States Treasury constant maturity rate for the expected life of the stock option. The expected life of a stock award is the period of time that the award is expected to be outstanding.

We recognize compensation expense for all stock-based awards on a straight-line basis over the requisite service period for the entire award. The amount of compensation expense recognized through the end of each reporting period is equal to the portion of the grant-date value of the awards that have vested, or for partially vested awards, the value of the portion of the award that is ultimately expected to vest for which the requisite services have been provided. The benefits of tax deductions in excess of recognized compensation cost are reported as a financing cash flow.

As of September 30, 2021, there were no stock-based compensation awards outstanding.

Other Income, Net

Other income, net, consists of interest income /expense, foreign exchange gains and losses and other non-operating gains and losses.

Income Taxes

We account for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is not determinable beyond a “more likely than not” standard, we establish a valuation allowance. To the extent we establish a valuation allowance or increase or decrease this allowance in a period, we include an expense or benefit within the tax provision in the statement of operations. We also utilize a “more likely than not” recognition threshold and measurement analysis for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize potential accrued interest and penalties related to unrecognized tax benefits within the statement of operations as income tax expense.

We operate within multiple tax jurisdictions and are subject to audit in these jurisdictions. Our foreign subsidiaries are subject to foreign income taxes on earnings in their respective jurisdictions. Earnings of our foreign subsidiaries that constitute Global Intangible Low Taxed Income (“GILTI”) are included in U.S. taxable income with related taxes recorded as a current period income tax expense.

Foreign Currency Translation

The functional currency of our Chinese subsidiary is the Chinese Yuan Renminbi. The functional currency for our Hong Kong and Singapore subsidiaries is the United States dollar. Assets and liabilities are translated into United States dollars at the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the respective periods. Foreign currency transaction and remeasurement gains and losses are included in results of operations.

Segment Reporting

We operate in one reportable segment: the manufacture and sale of force sensing technology solutions.

Comprehensive Income

Comprehensive income includes all components of comprehensive income, including net income and any changes in equity during the period from transactions and other events and circumstances generated by non-owner sources.

Earnings Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of diluted common shares, which is inclusive of common stock equivalents from unexercised stock options and restricted stock units. Unexercised stock options and restricted stock units are considered to be common stock equivalents if, using the treasury stock method, they are determined to be dilutive.

Under the two-class method of determining earnings for each class of stock, we consider the dividend rights and participating rights in undistributed earnings for each class of stock.

Leases

The Company accounts for its leases under ASC Topic 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases, and are recorded on the consolidated balance sheets as both a right-of-use (“ROU”) asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the ROU asset is amortized over the lease term. For finance leases, interest on the lease liability and the amortization of the ROU asset results in front-loaded expense over the lease term. Variable lease expenses are recorded when incurred.

In calculating the ROU asset and lease liability, the Company has elected to combine lease and non-lease components. The Company excludes short-term leases having initial term of 12 months or less from this guidance as an accounting policy election, and recognizes rent expense for such short-term leases on a straight-line basis over the lease term.

Risk and Uncertainties

Our future results of operations involve a number of risks and uncertainties. Factors that could affect our business or future results and cause actual results to vary materially from historical results include, but are not limited to, the rapid change in our industry; problems with the performance, reliability or quality of our products; loss of customers; impacts of doing business internationally, including foreign currency fluctuations; potential shortages of the supplies we use to manufacture our products; disruptions in our manufacturing facilities; changes in environmental directives impacting our manufacturing process or product lines; the development of new proprietary technology and the enforcement of intellectual property rights by or against us; our ability to attract and retain qualified employees; and our ability to raise additional capital.

Public Health Threats

Public health threats could adversely affect our ongoing or planned business operations. For example, the COVID-19 pandemic resulted in quarantines, restrictions on travel and other business and economic disruptions. We cannot presently predict the scope and severity of any potential business shutdowns or disruptions from such public health threats, but if we or any of the third parties with whom we engage, including the suppliers, distributers, resellers and other third parties with whom we conduct business, were to experience shutdowns or other business disruptions, our ability to conduct our business in the manner and on the timelines we plan could be materially and adversely impacted.

Fair Value Measurements

We determine fair value measurements based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, we follow the following fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) our own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs):

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets;

Level 2: Other inputs observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborate inputs; and

Level 3: Unobservable inputs for which there is little or no market data and which requires the owner of the assets or liabilities to develop its own assumptions about how market participants would price these assets or liabilities.

Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy.

Note 3 – Earnings Per Share

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding stock options and restricted stock-based awards using the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share:

Note 6 – Income Taxes

Income tax expense as a percentage of pre-tax income was 11.9% for the three months ended September 30, 2021, versus tax benefit of 154.2% for the comparable period in the prior year. Income tax expense as a percentage of pre-tax income was 20.8% for the nine months ended September 30, 2021 versus tax benefit of 139.2% for the comparable period in the prior year . Our income tax expense/benefit is primarily impacted by permanent taxable differences, the mix of domestic and foreign pre-tax earnings, as well as our ability to utilize prior net operating loss carryforwards (“NOLs”).

The Company experienced an ownership change under IRC Section 382 in February 2010. In general, a Section 382 ownership change occurs if there is a cumulative change in our ownership by “5% shareholders” (as defined in the Internal Revenue Code of 1986, as amended) that exceeds 50 percentage points over a rolling three-year period. An ownership change generally affects the rate at which NOLs and potential other deferred tax assets are permitted to offset future taxable income. Certain state jurisdictions within

which we operate contain similar provisions and limitations. All of the remaining federal and state NOLs as of September 30, 2021 are subject to annual limitations due to the February 2010 ownership change.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. Given our current earnings and anticipated future earnings, we determine there is sufficient evidence to reach a conclusion that a valuation allowance is not warranted.

​

Note 7 – Commitments and Contingencies

Lease Agreements

We lease facilities under non-cancellable operating leases. The leases expire at various dates through fiscal 2023 and frequently include renewal provisions for varying periods of time, provisions which require us to pay taxes, insurance and maintenance costs, and provisions for minimum rent increases. Minimum leases payments, including scheduled rent increases are recognized as rent expenses on a straight-line basis over the term of the lease.

The rate implicit in each lease is not readily determinable, and we therefore use our incremental borrowing rate to determine the present value of the lease payments. The weighted average incremental borrowing rate used to determine the initial value of ROU assets and lease liabilities capitalized during the nine months ended September 30, 2021 and 2020 was 5.50% and 6.75%, respectively.

ROU assets for operating leases are periodically reduced by impairment losses. We use the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant and Equipment – Overall, to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to recognize. As of September 30, 2021, we have not recognized any impairment losses for our ROU assets.

We monitor for events or changes in circumstances that require a reassessment of our leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero. In that case, the amount of the adjustment that would result in a negative ROU asset balance is recorded in profit or loss.

In June 2020, the Company entered into a sublease agreement to lease 4,351 square feet of space located in Irvine, California for approximately $6 thousand per month with 3 percent annual increases, plus common area maintenance costs. The lease term began July 1, 2020 and ends May 31, 2023. The space is used for executive offices, sales, finance and administration.

The Company leases a 14,476 square-foot manufacturing facility and administrative office in Shenzhen, China. In May 2020, the Company renewed this lease for the period June 1, 2020 through May 31, 2022 for approximately $7 thousand per month through May 31, 2021 and increasing to approximately $8 thousand per month through May 31, 2022.

The Company leases a 275 square-foot engineering and administrative office in Singapore for approximately $1 thousand per month. This lease term ends May 2022.

The Company leases a 3,000 square-foot distribution facility in Hong Kong for approximately $2 thousand per month. This lease term ends April 2023.

The Company leases a 500 square-foot sales office in Tokyo, Japan for approximately $1 thousand per month. This lease term ends November 2022.

As of September 30, 2021, the Company had current and long-term lease liabilities of $150 thousand and $71 thousand, respectively, and ROU assets of $207 thousand. As of December 31, 2020, the Company had current and long-term lease liabilities of $219 thousand and $140 thousand, respectively, and ROU assets of $334 thousand. Future imputed interest as of September 30, 2021 totaled $10 thousand. The weighted average remaining lease term of the Company’s leases as of September 30, 2021 is 0.8 years.

​

During the three months ended September 30, 2021, we recognized approximately $68 thousand in operating lease costs,including approximately $29 thousand in cost of revenue and approximately $39 thousand in operating expenses. During the three months ended September 30, 2020, we recognized approximately $77 thousand in operating lease costs, including approximately $29 thousand in cost of revenue and approximately $48 thousand in operating expenses.

During the nine months ended September 30, 2021, we recognized approximately $234 thousand in operating lease costs, including approximately $88 thousand in cost of revenue and approximately $146 thousand in operating expenses. During the nine months ended September 30, 2020, we recognized approximately $187 thousand in operating lease costs, including approximately $73 thousand in cost of revenue and approximately $114 thousand in operating expenses.

Litigation

We are not party to any legal proceedings as of September 30, 2021. We are occasionally involved in legal proceedings in the ordinary course of business, including actions against us which assert or may assert claims or seek to impose fines and penalties in substantial amounts. Related legal defense costs are expensed as incurred.

Warranties

We establish reserves for future product warranty costs that are expected to be incurred pursuant to specific warranty provisions with our customers. We generally warrant our products against defects for one year from date of shipment, with certain exceptions in which the warranty period can extend to more than one year based on contractual agreements. Our warranty reserves are established at the time of sale and updated throughout the warranty period based upon numerous factors including historical warranty return rates and expenses over various warranty periods. Historically, our warranty returns have not been material.

Intellectual Property Indemnities

We indemnify certain customers and our contract manufacturers against liability arising from third-party claims of intellectual property rights infringement related to our products. These indemnities appear in development and supply agreements with our customers as well as manufacturing service agreements with our contract manufacturers, are not limited in amount or duration and generally survive the expiration of the contract. Given that the amount of any potential liabilities related to such indemnities cannot be determined until an infringement claim has been made, we are unable to determine the maximum amount of losses that we could incur related to such indemnifications.

Director and Officer Indemnities and Contractual Guarantees

We have entered into indemnification agreements with our directors and executive officers, which require us to indemnify such individuals to the fullest extent permitted by Nevada law. Our indemnification obligations under such agreements are not limited in amount or duration. Certain costs incurred in connection with such indemnifications may be recovered under certain circumstances under various insurance policies. Given that the amount of any potential liabilities related to such indemnities cannot be determined until a lawsuit has been filed, we are unable to determine the maximum amount of losses that we could incur relating to such indemnities.

We have also entered into an employment agreement with Steven N. Bronson, our Chairman of the Board, President and Chief Executive Officer. This agreement contains certain severance and change in control obligations. Under the agreement, if Mr. Bronson’s employment is terminated due to his death or disability (as such terms are defined in the agreement), Mr. Bronson or his beneficiaries will be entitled to receive: (i) his base compensation to the end of the monthly pay period immediately following the date of termination; (ii) accrued bonus payments; and (iii) all unvested equity and/or options issued by the Company shall immediately fully vest. If Mr. Bronson’s employment is terminated by him for good reason (as such term is defined in the agreement), or by us without cause, then Mr. Bronson will be entitled to receive: (i) his base compensation to the date of termination; (ii) a severance payment equal to twelve months of his base compensation; (iii) any earned bonus compensation; (iv) employee benefits for twelve months following the date of termination; (v) any vested company match 401k or other retirement contribution; and (vi) all unvested equity and/or options issued by the Company shall immediately fully vest.

In the event of a change in control of the Company (as such term is defined in the agreement), Mr. Bronson is entitled to receive: (i) a change in control payment in an amount equal to twelve months of his base compensation, payable as of the date the change in control occurs; and (ii) all unvested equity and/or options issued by the Company shall immediately fully vest.

Guarantees and Indemnities

In the normal course of business, we are occasionally required to undertake indemnification for which we may be required to make future payments under specific circumstances. We review our exposure under such obligations no less than annually, or more frequently as required. The amount of any potential liabilities related to such obligations cannot be accurately determined until a formal claim is filed. Historically, any such amounts that become payable have not had a material negative effect our business, financial condition or results of operations. We maintain general and product liability insurance which may provide a source of recovery to us in the event of an indemnification claim.

Series A Convertible Preferred Stock

​

On October 21, 2021, the Company entered into a securities purchase agreement with twenty one (21) investors, pursuant to which the Company sold to the investors an aggregate of one hundred twenty thousand (120,000) shares of its 8.0% Series A Convertible Preferred Stock, par value $0.01 per share, at an offering price of $25.00 per share, for gross proceeds of $3.0 million. Each share of Series A Convertible Preferred Stock is convertible into shares of the Company’s common stock at a conversion price of $12.50 per common share, or 2.0 shares of common stock, at any time at the option of the holder, subject to certain customary adjustments. The Company may elect to automatically convert some or all of the Series A Convertible Preferred Stock into shares of common stock at any time on or after April 22, 2022 if the closing price of the common stock equals or exceeds $15.00 (120% of the initial conversion price) for at least 20 out of 30 consecutive trading days ending within five trading days prior to the notice of automatic conversion. The offering closed on October 22, 2021. After payment of placement agent cash fees and expenses of the offering, the Company received net proceeds of approximately $2.82 million.

Significant market opportunities are rapidly emerging for us to improve upon the functionality of standard capacitive sensors which are widely available and competitively priced. Inadvertent activation, where users unintentionally activate a control, is a common problem with capacitive technology. In contrast, force sensing solutions require a deliberate application of force to operate. We have had recent success in using our force sensing solutions in combination with capacitive technologies to minimize the latter’s performance issues, enabling force sensing solutions to complement competitive technologies and provide hybrid solutions and open up new opportunities for growth. We continue to simultaneously expand our standard product portfolio and develop new technology platforms to grow existing markets and capture emerging markets. This portfolio expansion will incorporate other complimentary sensing technologies. This broader portfolio of technologies will allow us to use our expertise in integrating multiple sensing technologies for applications in the rapidly growing Internet-of-Things (“IoT”).

Interlink serves our world-wide customer base from our corporate headquarters in Irvine, California (Orange County) and from our facility in Camarillo, California (Ventura County). We have established a Global Product Development and Materials Science Center in our Camarillo footprint. This facility has a state-of-the-art printed electronics development laboratory as well as materials science lab. Our engineering team is based in this center where we work with our U.S. and global customers on developing, engineering, prototyping and implementing our advanced HMI solutions. We also maintain a small embedded software and IoT application development center in Singapore. We manufacture all our products in our printed electronics manufacturing facility in Shenzhen, China. In addition, we maintain a global distribution and logistics center in Hong Kong, a technical sales office in Japan, and several manufacturer representatives and distributors in strategic locations in our key markets, all of which allows us to support our global customer base. We sell our products in a wide range of markets, including consumer electronics, automotive, industrial and medical. Our customers are some of the world’s largest companies and most recognizable brands.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our future financial statements presentation, financial condition, results of operations, and cash flows will be affected.

A description of our critical accounting policies that represent the more significant judgments and estimates used in the preparation of our financial statements was provided in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 17, 2021. There have been no changes to our critical accounting policies and estimates described in the Form 10-K that have had a material impact on our condensed consolidated financial statements and related notes.

Recently Issued and Adopted Accounting Pronouncements

We reviewed all recently issued accounting pronouncements and concluded they are all not applicable or not expected to be material to our financial statements.

We sell our custom products into the industrial, medical and consumer markets. We previously sold custom products in the automotive market and continue to pursue opportunities in that sector. We sell our standard products through various distribution networks. The ultimate customer for standard products may come from different markets which are often unknown to us at the time of sale. Each market has different product design cycles. Products with longer design cycles often have much longer product life-cycles. Industrial and medical products generally have longer design and life-cycles than consumer products. We currently have products with life-cycles that have exceeded twenty years and are ongoing.

Revenues were up in the three months ended September 30, 2021 compared to the three months ended September 30, 2020 in the industrial and medical markets, and for our standard products. The increase in revenue from our industrial market customers was due to increased purchasing volume by these customers for use in their ongoing product lines resulting from changes in demand by their customers. The increase in revenue from our medical market customers was due to an increase in purchasing levels by these customers in the current year as compared to the pandemic-impacted levels in the prior year. The cyclical purchasing pattern of some of our larger customers affects our revenues on a quarterly basis. In the normal cycle, our larger customers tend to purchase in bulk quantities and consume these products over several financial reporting periods. In all markets, the timing of orders from our customers is not always predictable and can be concentrated in varying periods during the year to coincide with their project and building plans.

Income tax expense reflects statutory tax rates in the jurisdictions that we operate adjusted for book/tax differences. The tax expense (benefit) for the three month periods ended September 30, 2021 and 2020 was a result of taxable income (losses) in the domestic and foreign jurisdictions in which we operate, including the effects of permanent taxable differences.

Our effective tax rate is directly affected by the relative proportions of income before taxes in the jurisdictions in which we operate. Discrete tax events and permanent taxable differences may cause our effective rate to fluctuate on a quarterly basis. Certain events, including, for example, acquisitions and other business changes, which are difficult to predict, may also cause our effective tax rate to fluctuate. We are subject to changing tax laws, regulations, and interpretations in multiple jurisdictions. Continued corporate tax reform continues to be a priority in the U.S. and other jurisdictions. Additional changes to the tax system in the U.S. could have significant effects, positive and negative, on our effective tax rate, and on our deferred tax assets and liabilities.

​

Income tax expense (benefit) reflects statutory tax rates in the jurisdictions that we operate adjusted for book/tax differences. The tax expense (benefit) for the nine month periods ended September 30, 2021 and 2020 was a result of taxable income (losses) in the domestic and foreign jurisdictions in which we operate, including the effects of permanent taxable differences.

Liquidity and Capital Resources

Cash requirements for working capital and capital expenditures have been funded from cash balances on hand and cash generated from operations. As of September 30, 2021, we had cash and cash equivalents of $6.647 million, working capital of $7.867 million, and no indebtedness. Cash and cash equivalents consist of cash and money market funds. We did not have any short-term or long-term marketable investments as of September 30, 2021. Of the $6.647 million of cash balances on hand, $2.565 million was held by foreign subsidiaries. If these funds are needed for our operations in the U.S., we have several methods to repatriate without significant tax effects, including repayment of intercompany loans or distributions of previously taxed income. Other distributions may require us to incur U.S. or foreign taxes to repatriate these funds. However, our intent is to permanently reinvest these funds outside the U.S. and our current plans do not demonstrate a need to repatriate cash to fund our U.S. operations.

During the second quarter of 2020, the Company received a loan in the aggregate principal amount of $186 thousand pursuant to the PPP under the Coronavirus Aid, Relief, and Economic Security Act. The full amount of the loan principal and interest was forgiven in the first quarter of 2021.

We believe that our existing cash and cash equivalents balance will be sufficient to maintain our current operations considering our current financial condition, obligations, and other expected cash flows. If our circumstances change, however, we may require additional cash. If we require additional cash, we may attempt to raise additional capital through equity, equity-linked or debt financing arrangements. If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders will be diluted. If we raise additional financing by the incurrence of indebtedness, we could be subject to fixed payment obligations and could also be subject to restrictive covenants, such as limitations on our ability to incur additional debt, and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to raise additional needed funds, we may also take measures to reduce expenses to offset any shortfall.

Net Cash Provided By Operating Activities

For the nine months ended September 30, 2021, the $639 thousand of cash provided by operating activities was attributable to net income of $243 thousand, adjusted for non-cash charges of $235 thousand, non-cash gain on forgiveness of PPP loan of $186 thousand, and cash provided by changes in operating assets and liabilities of $347 thousand.

Accounts receivable decreased slightly from $1,113 thousand at December 31, 2020 to $1,106 thousand at September 30, 2021 due to timing of shipments and payments during the third quarter of 2021 compared to the fourth quarter of 2020. Many of our customers pay promptly and accounts receivable is generally related to the most recent shipments. Inventories decreased slightly from $866 thousand at December 31, 2020 to $807 thousand at September 30, 2021. Inventory balances fluctuate depending on the timing of materials purchases and product shipments. Prepaid expenses and other current assets decreased from $392 thousand at December 31, 2020 to $325 thousand at September 30, 2021, and accounts payable and accrued liabilities increased from $578 thousand at December 31, 2020 to $685 thousand at September 30, 2021, primarily due to the timing of payment for purchases of materials and other services provided.

Net Cash (Used In) Investing Activities

Net cash used in investing activities of $142 thousand for the nine months ended September 30, 2021 consisted of purchases of property, plant, and equipment, primarily related to completion of the Global Product Development and Materials Science Center in our Camarillo footprint. Net cash used in investing activities of $66 thousand for the nine months ended September 30, 2020 consisted of legal costs related to securing patents on new products and processes developed thereunder.

​

Net Cash Provided By Financing Activities

There was no cash provided by or used in financing activities during the nine months ended September 30, 2021. Net cash provided by financing activities for the nine months ended September 30, 2020 was attributable to proceeds from the PPP loan.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The phrase “disclosure controls and procedures” refers to controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended, or the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the U.S. Securities and Exchange Commission, or SEC. Disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to our management, including our chief executive officer, or CEO, and chief financial officer, or CFO, as appropriate to allow timely decision regarding required disclosure.

Our management, with the participation of our CEO and CFO, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of September 30, 2021, the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our CEO and CFO had concluded that as of September 30, 2021, our disclosure controls and procedures were designed at a reasonable assurance level and were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Controls over Financial Reporting

There was no change in our internal control over financial reporting during the period ended September 30, 2021 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.
