- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

1. Business Description, Basis of Presentation and Significant Accounting Policies

Business Description:

ClearOne, Inc., together with its subsidiaries (collectively, “ClearOne” or the “Company”), is a global market leader enabling conferencing, collaboration, and network streaming solutions. The performance and simplicity of our advanced, comprehensive solutions offer unprecedented levels of functionality, reliability and scalability.

Basis of Presentation:

Fiscal Year – This report on Form 10-K includes consolidated balance sheets for the years ended December 31, 2022 and 2021 and the related consolidated statements of operations and comprehensive income (loss), shareholders' equity, and cash flows for each of the years ended December 31, 2022 and 2021.

Consolidation – These consolidated financial statements include the financial statements of ClearOne, Inc. and its wholly owned subsidiaries. All inter-Company accounts and transactions have been eliminated in consolidation.

Use of Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting periods. Key estimates in the accompanying consolidated financial statements include, among others, revenue recognition, allowances for doubtful accounts receivable and product returns, provisions for obsolete inventory, potential impairment of long-lived assets, and deferred income tax asset valuation allowances. Actual results could differ materially from these estimates.

Foreign Currency Translation – We are exposed to foreign currency exchange risk through our foreign subsidiaries. Other than our subsidiaries in India and Spain, all other foreign subsidiaries are U.S. dollar functional, for which gains and losses arising from remeasurement are included in earnings. Our Spanish subsidiary is Euro functional, for which gains and losses arising from translation are included in accumulated other comprehensive income or loss. Our Indian subsidiary is Indian Rupee functional, for which gains and losses arising from translation are included in accumulated other comprehensive income or loss. We translate and remeasure foreign assets and liabilities at exchange rates in effect at the balance sheet dates. We translate revenue and expenses using average rates during the year.

Concentration Risk – We depend on an outsourced manufacturing strategy for our products. We outsource the manufacture of all of our products to third party manufacturers located in Asia. If any of these manufacturers experience difficulties in obtaining sufficient supplies of components, component prices significantly exceeding the anticipated costs, an interruption in their operations, or otherwise suffer capacity constraints, we would experience a delay in production and shipping of these products, which would have a negative impact on our revenues. Should there be any disruption in services due to natural disaster, economic or political difficulties, transportation restrictions, acts of terror, quarantine or other restrictions associated with infectious diseases, or other similar events, or any other reason, such disruption may have a material adverse effect on our business. Operating in the international environment exposes us to certain inherent risks, including unexpected changes in regulatory requirements and tariffs, and potentially adverse tax consequences, which could materially affect our results of operations. Currently, we have no second source of manufacturing for most of our products.

Significant Accounting Policies:

Cash Equivalents – The Company considers all highly-liquid investments with a maturity of three months or less, when purchased, to be cash equivalents. The Company places its temporary cash investments with high-quality financial institutions. At times, such investments may be in excess of the Federal Deposit Insurance Corporation insurance limits. As of December 31, 2022, there was one cash account that exceeded federally insured limits, in the amount of $564.

Marketable Securities - The Company has classified its marketable securities as available-for-sale securities. These debt securities are carried at estimated fair value with unrealized holding gains and losses included in other comprehensive income (loss) in shareholders’ equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Dividend and interest income are recognized when earned.

A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and establishes a new cost basis for the security. Losses are charged against “Other income” when a decline in fair value is determined to be other than temporary. We review several factors to determine whether a loss is other than temporary. These factors include, but are not limited to: (i) the extent to which the fair value is less than cost and the cause for the fair value decline, (ii) the financial condition and near term prospects of the issuer, (iii) the length of time a security is in an unrealized loss position and (iv) our ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. There were no other-than-temporary impairments recognized during the years ended December 31, 2022 and 2021.

Accounts Receivable – Accounts receivable are recorded at the invoiced amount, net of expected returns and allowance for doubtful accounts. Generally, credit is granted to customers on a short-term basis without requiring collateral, and as such, these accounts receivable, do not bear interest, although a finance charge may be applied to such receivables that are past due. The Company extends credit to customers who it believes have the financial strength to pay. The Company has in place credit policies and procedures, an approval process for sales returns and credit memos, and processes for managing and monitoring channel inventory levels.

The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. Management regularly analyzes accounts receivable including current aging, historical write-off experience, customer concentrations, customer creditworthiness, and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. We review customer accounts quarterly by first assessing accounts with aging over a specific duration and balance over a specific amount. We review all other balances on a pooled basis based on past collection experience. Accounts identified in our customer-level review as exceeding certain thresholds are assessed for potential allowance adjustment if we conclude the financial condition of that customer has deteriorated, adversely affecting their ability to make payments. Delinquent account balances are written off if the Company determines that the likelihood of collection is not probable. If the assumptions that are used to determine the allowance for doubtful accounts change, the Company may have to provide for a greater level of expense in future periods or reverse amounts provided in prior periods.

The Company’s allowance for doubtful accounts activity for the years ended December 31, 2022 and 2021 is as follows:

	Year Ended December 31,
	2022		2021
Balance at beginning of the year	$	326	$	506
Allowance increase (decrease)		—		(180	)
Write offs, net of recoveries		—		—
Balance at end of the year	$	326	$	326

Inventories – Inventories are valued at the lower of cost or market, with cost computed on a first-in, first-out (“FIFO”) basis. In addition to the price of the product purchased, the cost of inventory includes the Company’s internal manufacturing costs, including warehousing, engineering, material purchasing, quality and product planning expenses and applicable overhead, not in excess of estimated realizable value. Consideration is given to obsolescence, excessive levels, deterioration, direct selling expenses, and other factors in evaluating net realizable value.

The inventory also includes advance replacement units (valued at cost) provided by the Company to end-users to service defective products under warranty. The value of advance replacement units included in the inventory was $193 and $130, as of December 31, 2022 and 2021, respectively.

The inventory consists of current inventory of $8,961 and long-term inventory of $2,707. Long term inventory represents inventory held in excess of our current (next 12 months) requirements based on our recent sales and forecasted level of sales.

Property and Equipment – Property and equipment are stated at cost less accumulated depreciation and amortization. Expenditures that materially increase values or capacities or extend useful lives of property and equipment are capitalized. Routine maintenance, repairs, and renewal costs are expensed as incurred. Gains or losses from the sale, trade-in, or retirement of property and equipment are recorded in current operations and the related book value of the property is removed from property and equipment accounts and the related accumulated depreciation and amortization accounts. Estimated useful lives are generally two to ten years. Depreciation and amortization are calculated over the estimated useful lives of the respective assets using the straight-line method. Leasehold improvement amortization is computed using the straight-line method over the shorter of the lease term or the estimated useful life of the related assets.

Intangible Assets – Intangible assets are amortized over their useful lives unless these lives are determined to be indefinite. Intangible assets are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, which are generally three to ten years. Intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized.

Impairment of Long-Lived Assets - Long-lived assets, such as property, equipment, and definite-lived intangible assets subject to depreciation and amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to estimated future undiscounted net cash flows of the related asset or group of assets over their remaining lives. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized for the amount by which the carrying amount exceeds the estimated fair value of the asset. Impairment of long-lived assets is assessed at the lowest levels for which there are identifiable cash flows that are independent of other groups of assets. The impairment of long-lived assets requires judgments and estimates. If circumstances change, such estimates could also change. Assets held for sale are reported at the lower of the carrying amount or fair value, less the estimated costs to sell.

Leases: We determine if an arrangement is a lease at inception. Operating leases are included in operating lease - right of use (“ROU”) assets, accrued liabilities, and operating lease liability in our consolidated balance sheets. As of adoption of ASC 842 and as of December 31, 2022 and December 31, 2021, the Company was not party to finance lease arrangements. ROU assets represent our right to use an underlying asset for the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and operating lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Under the available practical expedient, we account for the lease and non-lease components as a single lease component.

Revenue Recognition Policy: The Company generates revenue from sales of its audio and video conferencing equipment to distributors, system integrators and value-added resellers. The Company also generates revenue, to a much lesser extent, from sale of software and licenses to distributors, system integrators, value-added resellers and end-users. The Company recognizes revenue when it satisfies a performance obligation in an amount reflecting the consideration to which it expects to be entitled. For sales agreements, the Company has identified the promise to transfer products, each of which are distinct, to be the performance obligation. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations in the contract and (5) recognizing revenue when the performance obligation is satisfied. Substantially all of the Company’s revenue is recognized at the time control of the products transfers to the customer.

Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty and supply, but typically do not require mandatory purchase commitments. In the absence of a sales agreement, the Company’s standard terms and conditions at the time of acceptance of purchase orders apply. The Company considers the customer purchase orders, governed by sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. The Company evaluates certain factors including the customer’s ability to pay (or credit risk).

In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. Sales to distributors, are typically made pursuant to agreements that provide return rights with respect to discontinued or slow-moving products, referred to as stock rotation. Sales to distributors can also be subject to price adjustment on certain products, primarily for distributors with drop-shipping rights. Although payment terms vary, most distributor agreements require payment within 45 days of invoicing.

The Company recognizes revenue when it satisfies a performance obligation. The Company recognizes revenue from sales agreements upon transferring control of a product to the customer. This typically occurs when products are shipped or delivered, depending on the delivery terms, or when products that are consigned at customer locations are sold to dealers or end users. Revenue recognized during the twelve months ended December 31, 2022 for equipment sales was $25,104, and for software, licenses, etc. was $101. Sales returns and allowances are estimated based on historical experience. Provisions for discounts and rebates to customers, estimated returns and allowances, ship and credit claims and other adjustments are provided for in the same period the related revenues are recognized, and are netted against revenues. For returns, the Company recognizes a related asset for the right to recover returned products with a corresponding reduction to cost of goods sold. The Company reviews warranty and related claims activity and records provisions, as necessary.

Frequently, the Company receives orders with multiple delivery dates that may extend across reporting periods. Since each delivery constitutes a performance obligation, the Company allocates the transaction price of the contract to each performance obligation based on the stand-alone selling price of the products. The Company invoices the customer for each delivery upon shipment and recognizes revenues in accordance with delivery terms. Although payment terms vary, distributors typically pay within 45 days of invoicing and dealers pay within 30 days of invoicing. As scheduled delivery dates are within one year, revenue allocated to future shipments of partially completed contracts are not disclosed.

The Company has elected to record freight and handling costs associated with outbound freight after control over a product has transferred to a customer as a fulfillment cost and include it in cost of revenues. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenues) in the consolidated statements of operations and comprehensive income (loss).

The details of deferred revenue and associated cost of goods sold and gross profit are as follows:

	As of December 31,
	2022		2021
Deferred revenue	$	63	$	54
Deferred cost of goods sold		—		—
Deferred gross profit	$	63	$	54

The Company offers rebates and market development funds to certain of its distributors, dealers/resellers, and end-users based upon the volume of product purchased by them. The Company records rebates as a reduction of revenue in accordance with GAAP.

The Company provides, at its discretion, advance replacement units to end-users on defective units of certain products under warranty. Since the purpose of these units is not revenue generating, the Company tracks the units due from the end-user, until the defective unit has been returned. Any amount due from the customer upon failure to return the products is accounted as receivable only after establishing customer's failure to return the products. The inventory due from the customer is accounted at cost or market value whichever is lower.

The following table disaggregates the Company’s revenue into primary product groups:

	Year Ended December 31,
	2022		2021
Audio Conferencing	$	11,829	$	11,568
Microphones		9,824		10,963
Video products		3,552		6,436
	$	25,205	$	28,967

The following table disaggregates the Company’s revenue into major regions:

	Year Ended December 31,
	2022		2021
North and South America	$	12,297	$	14,042
Asia (including Middle East) and Australia		7,828		8,197
Europe and Africa		5,080		6,728
	$	25,205	$	28,967

Warranty Costs – The Company accrues for warranty costs based on estimated warranty return rates and estimated costs to repair. These reserve costs are classified as accrued liabilities on the consolidated balance sheets. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty returns, and repair cost. The Company reviews the adequacy of its recorded warranty accrual on a quarterly basis.

The details of changes in the Company’s warranty accrual are as follows:

	Year Ended December 31,
	2022		2021
Balance at the beginning of year	$	194	$	194
Accruals/additions		—		—
Usage/claims		—		—
Balance at end of year	$	194	$	194

Advertising – The Company expenses advertising costs as incurred. Advertising costs consist of trade shows, magazine advertisements, and other forms of media. Advertising expenses for the years ended December 31, 2022 and 2021 totaled $572 and $508, respectively, and are included in sales and marketing on the consolidated statements of operations and comprehensive income (loss).

Income Taxes – The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carry-forwards. These temporary differences will result in deductible or taxable amounts in future years when the reported amounts of the assets or liabilities are recovered or settled. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some or all of the deferred tax assets may not be realized. On a quarterly basis, the Company tests the value of deferred tax assets for impairment at the taxpaying-component level within each tax jurisdiction. Significant judgment and estimates are required in determining whether valuation allowances should be established as well as the amount of such allowances.

The valuation allowance is based on our estimates of future taxable income and the period over which we expect the deferred tax assets to be recovered. Our assessment of future taxable income is based on historical experience and current and anticipated market and economic conditions and trends. In 2018, as a result of negative evidence, principally three years of cumulative pre-tax operating losses, we concluded that it was more likely than not that net operating losses, tax credits and other deferred tax assets were not realizable and therefore, we recorded a full valuation allowance against those net deferred tax assets. We continue to record full valuation against our net deferred tax assets. Adjustments to the valuation allowance increase or decrease the Company’s income tax provision or benefit.

As of December 31, 2022 the Company had no net deferred tax assets due to valuation allowances recorded to account for the consecutive quarters with losses before taxes.

Recent changes: There were no changes that had a material impact on the Company's consolidated financial position, results of operations or cash flows.

Earnings Per Share – The following table sets forth the computation of basic and diluted loss per common share:

	Year Ended December 31,
	2022		2021
Numerator:
Net income (loss)	$	20,556	$	(7,694	)
Interest adjustment under if-converted method		285		—
		20,841		(7,694	)

Denominator:
Basic weighted average shares		23,937,962		19,859,817
Dilutive common stock equivalents using if-converted method		909,953		—
Diluted weighted average shares		25,189,147		19,859,817

Basic income (loss) per common share:	$	0.86	$	(0.39	)
Diluted income (loss) per common share:	$	0.83	$	(0.39	)

Weighted average options, warrants and convertible portion of senior convertible notes outstanding		6,788,671		4,654,601
Anti-dilutive options, warrants and convertible portion of senior convertible notes not included in the computation		5,510,600		4,654,601

Share-Based Payment – We estimate the fair value of stock options using the Black-Scholes option-pricing model, which requires certain estimates, including an expected forfeiture rate and expected term of options granted. We also make decisions regarding the method of calculating expected volatilities and the risk-free interest rate used in the option-pricing model. The resulting calculated fair value of stock options is recognized as compensation expense over the requisite service period, which is generally the vesting period. When there are changes to the assumptions used in the option-pricing model, including fluctuations in the market price of our common stock, there will be variations in the calculated fair value of our future stock option awards, which results in variation in the compensation cost recognized.

Other recent accounting pronouncements: The Company has determined that other recently issued accounting standards will not have a material impact on its consolidated financial position, results of operations or cash flows.

Liquidity:

As of December 31, 2022, cash and cash equivalents were approximately $984 compared to $1,071 as of December 31, 2021. Our working capital was $69,307 as of December 31, 2022 compared to $17,969 as of December 31, 2021. Net cash used in operating activities was $4,179 for the twelve months ended December 31, 2022, a decrease of cash used of $215 from $4,394 of cash used in operating activities in the twelve months ended December 31, 2021.

In order to maintain liquidity, the Company has been actively engaged in preserving cash by implementing company-wide cost reduction measures and raising additional capital. The company raised additional capital in 2019 by issuing senior convertible notes, in 2020 by borrowing through the CARES Act Paycheck Protection Program and issuing common stock and warrants and in 2021 by issuing short-term notes and issuing common stock and warrants. In January 2022, the Company issued $2,000 in common stock as consideration for the cancellation and termination of the short-term notes. In October 2022, the Company issued short term notes to raise $2,000. In addition, the Company has been generating additional cash as our inventory levels are brought down to historical levels.

The Company also believes that the Company's core strategies of product innovation and prudent cost management will bring the company back to profitability in the future. The Company believes, although there can be no assurance, that all of these measures and effective management of working capital, along with the current cash balance after the receipt of proceeds from legal settlement, will provide the liquidity needed to meet our operating needs through at least March 31, 2024.

Patents and technological know-how as of December 31, 2021 include capitalized legal expenses, net of amortization of $22,637 related to our defense of patents from infringement by our competitors. Legal expenses were capitalized upon satisfaction of two conditions: (a) a determination being made that a successful defense of this litigation is probable, and (b) that the monetary benefits arising out of such successful defense will be in excess of the costs for the defense. The Company capitalized $737 and $7,836 of litigation expenses related to this matter during the twelve months ended December 31, 2022 and 2021, respectively. A gain of $33,623 was recognized and included under other income after deducting the entire capitalized legal costs amounting to $27,374 net of amortized costs of $5,997 from the one-time legal settlement amount of $55,000, which is included in the balance sheet under legal settlement receivable as of December 31, 2022. Please refer to Note 8 - Commitments and Contingencies for additional information.

During the years ended December 31, 2022 and 2021, amortization of these intangible assets were$2,512 and $2,288 respectively.

8. Commitments and Contingencies

We establish contingent liabilities when a particular contingency is both probable and estimable. The Company is not aware of any pending claims or assessments, other than as described below, which may have a material adverse impact on the Company’s financial position or results of operations.

Outsource Manufacturers. We have manufacturing agreements with electronics manufacturing service (“EMS”) providers related to the outsourced manufacturing of our products. Certain manufacturing agreements establish annual volume commitments. We are also obligated to repurchase Company-forecasted but unused materials. The Company has non-cancellable, non-returnable, and long-lead time commitments with its EMS providers and certain suppliers for inventory components that will be used in production. The Company’s purchase commitments under such agreements is approximately $2,035 as of December 31, 2022.

Uncertain Tax Positions. As further discussed in Note 13 - Income Taxes, we had $962 of uncertain tax positions as of December 31, 2022. Due to the inherent uncertainty of the underlying tax positions, it is not possible to forecast the payment of this liability to any particular year.

Legal Proceedings.

Intellectual Property Litigation

The Company has been involved in several litigation proceedings (collectively, the “Litigations”) against Shure Incorporated (“Shure”) as more fully described in the Part I, Item 3 of the Company’s annual report on Form 10-K for the year ended December 31, 2021, as supplemented in Part II, Item 1 of the Company’s quarterly report on Form 10-Q for the quarter ended September 30, 2022.

On December 9, 2022, the Company and Shure entered into a confidential settlement and license agreement (the “Agreement”). Under the terms of the Agreement:

●	All of the Litigations between the parties were dismissed with prejudice and each of the Company and Shure released all claims against the other arising from or in connection with the matters that were subject to the Litigations;
●	Shure made a one-time settlement payment to the Company in the amount of $55,000 within five days after the dismissal of the Litigations in accordance with the Agreement in January 2023; and
●	The Company and Shure agreed to certain patent licenses and covenants not to sue.

The Company capitalized $737 and $7,836 of litigation expenses related to this matter during the twelve months ended December 31, 2022 and 2021, respectively.

A gain of $33,623 was recognized and included under other income after deducting the entire capitalized legal costs amounting to $27,374 net of amortized costs of $5,997 from the one-time legal settlement amount of $55,000, which is included in the balance sheet under legal settlement receivable as of December 31, 2022.

In addition, the Company is also involved from time to time in various claims and legal proceedings which arise in the normal course of our business. Such matters are subject to many uncertainties and outcomes that are not predictable. However, based on the information available to us, we do not believe any such other proceedings will have a material adverse effect on our business, results of operations, financial position, or liquidity.

Conclusion

We believe there are no other items that will have a material adverse impact on the Company’s financial position or results of operations. Legal proceedings are subject to all of the risks and uncertainties of legal proceedings and there can be no assurance as to the probable result of any legal proceedings.

The Company believes it has adequately accrued for the aforementioned contingent liabilities. If adverse outcomes were to occur, our financial position, results of operations and cash flows could be negatively affected materially for the period in which the adverse outcomes are known.

Senior Convertible Notes and Warrants

On December 17, 2019, the Company completed the issuance and sale of $3,000 aggregate principal amount of secured convertible notes of the Company (the “Notes”) and warrants (the “Warrants”) to purchase 340,909 shares of common stock, par value $0.001 per share of the Company (the “Common Stock”), in a private placement transaction. The Notes and Warrants were issued and sold to Edward D. Bagley, an affiliate of the Company, on the terms and conditions of a Note Purchase Agreement dated December 8, 2019 between the Company, certain subsidiary guarantors of the Company, and Mr. Bagley. Mr. Bagley is an affiliate of the Company and was the beneficial owner of approximately 46.6% of the Company’s issued and outstanding shares of Common Stock.

The Notes mature on December 17, 2023 (the “Maturity Date”) and accrue interest at a variable rate adjusted on a quarterly basis and equal to two and one-half percent (2.5%) over the greater of (x) five and one-quarter percent (5.25%) and (y) the Prime Rate as published in the Wall Street Journal (New York edition) as of the beginning of such calendar quarter. The Notes may be converted into shares of the Company’s Common Stock at any time at the election of Mr. Bagley at an initial conversion price of $2.11 per share (the “Conversion Price”), or 120% of the closing price of the Common Stock on December 6, 2019 as reported on the Nasdaq Capital Market. Also, the Company can cause a mandatory conversion of the Notes if the volume weighted average closing price of the Common Stock over 90 consecutive trading days exceeds 200% of the Conversion Price. In addition, the Notes may be redeemed by the Company for cash at any time after December 17, 2020 upon payment of the outstanding principal balance of the Notes and any unpaid and accrued interest. The Company also is required to redeem the Notes upon the occurrence of a change in control of the Company.

The Warrants have an initial exercise price equal to $1.76, the closing price of the Common Stock on December 6, 2019 as reported on the Nasdaq Capital Market, and are exercisable until December 17, 2026. The Warrants must be exercised for cash, unless at the time of exercise there is not a then effective registration statement for the resale of the shares of Common Stock issuable upon exercise of the Warrants, in which case the Warrants may be exercised via a cashless exercise feature that provides for net settlement of the shares of Common Stock issuable upon exercise.

Concurrent with the issuance of the Notes and Warrants pursuant to the Note Purchase Agreement, the Company, the Guarantors and Mr. Bagley entered into a Guaranty and Collateral Agreement (the “Collateral Agreement”) pursuant to which the Company and the Guarantors granted Mr. Bagley a first priority lien interest in all of the Company’s assets as security for the Company’s performance of its obligations under the Notes and Warrants.

The net proceeds after original issue discount and issuance costs of $346 were approximately $2,654. The Company expects to use the proceeds from the sale of the Notes and Warrants for general corporate purposes and working capital.

In accounting for the issuance of the Notes, the Company separated Notes and Warrants into liability and equity components. The carrying amount of Warrants, being an equity component, was first calculated using Black-Scholes method with the following assumptions:

Risk-free interest rate	1.82%
Expected life of Warrants (years)	7
Expected price volatility	49.94%
Expected dividend yield	0%

The carrying amount of the Notes was then determined by deducting the fair value of the Warrants from the principal amount of the Notes. The carrying amount of the Notes was further separated into equity and liability components after separating the value of the conversion feature into an equity component and leaving the remaining value as liability. The equity component is not remeasured while the Notes and Warrants continue to meet the conditions for equity classification for equity components.

The original issue discount and issuance costs are netted against the liability. The following table represents the carrying value of Notes and Warrants:

	December 31, 2022			December 31, 2021
Liability component:
Principal	$	1,920		$	2,640
Less: debt discount and issuance costs, net of amortization		(188	)		(385	)

Long-term portion of liability component included under long-term debt		—			1,920
Liability component total	$	1,920		$	2,640

(1) Recorded on the consolidated balance sheets as additional paid-in capital.

Debt discount and issuance costs are amortized over the life of the note to interest expense using the effective interest method. During the twelve months December 31, 2022 amortization of debt discount and issuance costs were $197 and $196 respectively. The following table represents schedule of maturities of principal amount contained in the Notes as of December 31, 2022:

2021 Short-term Bridge Loan

On July 2, 2021, the Company obtained a bridge loan in the principal amount of $2,000 from Edward D. Bagley (the “2021 Bridge Loan”), an affiliate of the Company. The Bridge Loan is evidenced by a promissory note dated July 2, 2021 (the “Note”) issued by the Company to Mr. Bagley.The Note bears interests at a rate of 8.0% per annum, matures on the earlier to occur of (i) October 1, 2021 or (ii) within two business days of the Company’s receipt of its expected U.S. federal income tax refund, and contains other customary covenants and events of default. On September 11, 2021, the Company amended and restated the terms of the 2021 Bridge Loan to extend the latest maturity date from October 1, 2021 to January 3, 2022. All other terms and conditions of the Bridge Loan remained the same. This Bridge Loan of $2,000 is included under short-term debt as of December 31, 2021. On January 4, 2022, the Company entered into a Securities Purchase Agreement with Edward D. Bagley, pursuant to which the Company issued and sold to Mr. Bagley, in a private placement 1,538,461 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share, at a purchase price of $1.30 per share of Common Stock. The consideration for the Shares was the cancellation and termination of Mr. Bagley’s outstanding bridge loan to the Company in the principal amount of $2,000 originally issued on July 2, 2021 and amended and restated on September 11, 2021. Mr. Bagley is an affiliate of the Company and the Company’s single largest stockholder.

Paycheck Protection Program Loan

On April 18, 2020, the Company, entered into a loan agreement with U.S. Bank National Association Bank, which provided for a loan in the principal amount of $1,499 (“PPP Loan”) pursuant to the Paycheck Protection Program under Division A, Title I of the CARES Act, which was enacted March 27, 2020. The PPP Loan had a two-year term and bears interest at a rate of 1.0% per annum. Monthly principal and interest payments are deferred for approximately sixteen months after the date of disbursement.

The Company's Paycheck Protection Program Loan ("PPP Loan") under the CARES Act was forgiven by Small Business Administration effective April 29, 2022. With this forgiveness, the Company is not required to repay the principal amount of $1,499 and the interest of $31. The Company received $953 back that it had already paid towards principal and interest payments toward the PPP Loan. The Company treated the forgiveness as extinguishment of debt in this quarter ended September 30, 2022 and reported the entire principal amount forgiven of $1,499 along with interest already accounted for of $29as a gain on extinguishment of debt included in other income.

2022 Bridge Loan

On October 28, 2022 the Company obtained a bridge loan in the principal amount of $2,000 from Edward D. Bagley (the “2022 Bridge Loan”), an affiliate of the Company.

Employee Stock Option Plans

The Company’s share-based incentive plan offering stock options is primarily through 2007 Equity Incentive Plan (the “2007 Plan”). Under this plan, one new share is issued for each stock option exercised. The plan is described below.

The 2007 Plan was restated and approved by the shareholders on December 12, 2016. Provisions of the restated 2007 Plan include the granting of up to 2,000,000 incentive and non-qualified stock options, stock appreciation rights, restricted stock and restricted stock units. Options may be granted to employees, officers, non-employee directors and other service providers and may be granted upon such terms as the Compensation Committee of the Board of Directors determines in their sole discretion.

All vesting schedules for options granted are based on 3 or 4-year vesting schedules, with either one-third or one-fourth vesting on the first anniversary and the remaining options vesting ratably over the remainder of the vesting term. Generally, directors and officers have 3-year vesting schedules and all other employees have 4-year vesting schedules. Additionally, in the event of a change in control or the occurrence of a corporate transaction, the Company’s Board of Directors has the authority to elect that all unvested options shall vest and become exercisable immediately prior to the event or closing of the transaction. As of December 31, 2022, the Company had 245,977 options with contractual lives of ten years and 242,500 options with contractual lives of 6 years.

As of December 31, 2022, there were 488,477 options outstanding under the 2007 Plan. As of December 31, 2022, the 2007 Plan had 976,377 authorized unissued options.

The Company uses judgment in determining the fair value of the share-based payments on the date of grant using an option-pricing model with assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the risk-free interest rate of the awards, the expected life of the awards, the expected volatility over the term of the awards, and the expected dividends of the awards. The Company uses the Black-Scholes option pricing model to determine the fair value of share-based payments granted under the guidelines of ASC Topic 718.

The Company did not grant any options during the year ended December 31, 2022.

In applying the Black-Scholes methodology to the 50,000 options granted during the year ended December 31, 2021, the Company used the following assumptions:

Risk free interest rate, average	0.84%
Expected option life, average	5 years
Expected price volatility, average	69.74%
Expected dividend yield	0%

The risk-free interest rate is determined using the U.S. Treasury rate in effect as of the date of the grant, based on the expected life of the stock option. The expected life of the stock option is determined using historical data.

The expected price volatility is determined using a weighted average of daily historical volatility of the Company’s stock price over the corresponding expected option life.

Under guidelines of ASC Topic 718, the Company recognizes the associated compensation cost for only those awards expected to vest on a straight-line basis over the underlying requisite service period. The Company estimated the forfeiture rates based on its historical experience and expectations about future forfeitures.

The following table shows the stock option activity:

	Number of Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value

The total pre-tax compensation cost related to stock options recognized during the years ended December 31, 2022 and 2021 was $112 and $131, respectively. Tax benefit from compensation cost related to stock options during the years ended December 31, 2022 and 2021, respectively was $28 and $0. As of December 31, 2022, the total compensation cost related to stock options not yet recognized and before the effect of any forfeitures was $152, which is expected to be recognized over approximately the next 2.65 years on a straight-line basis.

Employee Stock Purchase Plan

During the years ended December 31, 2022 and 2021, the Company issued shares to employees under the Company’s 2016 Employee Stock Purchase Plan (the “ESPP”). The ESPP was approved by the Company’s shareholders on December 12, 2016. As of December 31, 2022, and December 31, 2021, 395,524 and 402,704, respectively of the originally approved 500,000 shares were available for offerings under the ESPP. Offering periods under the ESPP commence on each Jan 1 and July 1 and continue for a duration of six months. The ESPP is available to all employees who do not own, or are deemed to own, shares of stock making up an excess of 5% of the combined voting power of the Company, its parent or subsidiary.

During each offering period, each eligible employee may purchase shares under the ESPP after authorizing payroll deductions. Under the ESPP, each employee may purchase up to the lesser of 2,500 shares or $25 of fair market value (based on the established purchase price) of the Company’s stock for each offering period. Unless the employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase common stock on the last business day of the period at a price equal to 85% (or a 15% discount) of the fair market value of the common stock on the first or last day of the offering period, whichever is lower.

Shares purchased and compensation expense associated with Employee Stock Purchase Plans were as follows:

	2022		2021
Shares purchased under ESPP plan		7,180		11,164
Plan compensation expense	$	1	$	5

Fair Value Measurements

12. Fair Value Mezasurements

The fair value of the Company’s financial instruments reflects the amounts that the Company estimates it will receive in connection with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. This category generally includes U.S. Government and agency securities; municipal securities; mutual funds and securities sold and not yet settled.

Level 3 - Unobservable inputs.

The substantial majority of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs.

There were no financial instruments that were re-measured by the Company as of December 31, 2022. The following tables set forth the fair value of the financial instruments re-measured by the Company as of December 31, 2021.

The Company has not provided for foreign withholding taxes on undistributed earnings of its non-U.S. subsidiaries since these earnings are intended to be reinvested indefinitely, in accordance with guidelines contained in ASC Topic 740, Accounting for Income Taxes. It is not practical to estimate the amount of additional taxes that might be payable on such undistributed earnings.

The Company routinely evaluates the likelihood of realizing the benefit of its deferred tax assets and may record a valuation allowance if, based on all available evidence, it determines that it is more likely than not some portion of the tax benefit will not be realized. As of December 31, 2022, the Company had an aggregate of approximately $13.5 million in deferred tax assets primarily related to intangible assets, net operating losses, tax credit carryforwards, and inventory basis differences. On a quarterly basis, the Company tests the value of deferred tax assets for impairment at the taxpaying-component level within each tax jurisdiction. Significant judgment and estimates are required in determining whether valuation allowances should be established as well as the amount of such allowances. When making such determination, consideration is given to, among other things, the following:

●	sufficient taxable income within the allowed carryback or carryforward periods;
●	future reversals of existing taxable temporary differences, including any tax planning strategies that could be utilized;
●	nature or character (e.g., ordinary vs. capital) of the deferred tax assets and liabilities; and
●	future taxable income exclusive of reversing temporary differences and carryforwards.

Based on the foregoing criteria, the Company determined that it does not meet the “more likely than not” threshold that net operating losses, tax credits and other deferred tax assets will be realized. Accordingly, the Company recorded a full valuation allowance at December 31, 2022.

As of December 31, 2022 the Company has federal net operating loss (“NOL”) carryforwards of approximately $0.4 million (pre-tax), state NOL carryforwards of approximately 0.8 million (pre-tax) and Spain NOL carryforwards of approximately $11.6 million (pre-tax). The federal NOL carryforward expires in 2029. The Spain NOL carryforward does not expire. The state NOL carryforwards expire over various periods.

Effective July 1, 2007, the Company adopted the accounting standards related to uncertain tax positions. This standard requires that tax positions be assessed using a two-step process. A tax position is recognized if it meets a “more likely than not” threshold, and is measured at the largest amount of benefit that is greater than 50 percent likely of being realized. Uncertain tax positions must be reviewed at each balance sheet date. Liabilities recorded as a result of this analysis must generally be recorded separately from any current or deferred income tax accounts.

The total amount of unrecognized tax benefits at December 31, 2022 and 2021, that would favorably impact our effective tax rate if recognized was $976 and $895, respectively. As of December 31, 2022 and 2021, we accrued $44 and $16, respectively, in interest and penalties related to unrecognized tax benefits. We account for interest expense and penalties for unrecognized tax benefits as part of our income tax provision.

Although we believe our estimates are reasonable, we can make no assurance that the final tax outcome of these matters will not be different from that which we have reflected in our historical income tax provisions and accruals. Such difference could have a material impact on our income tax provision and operating results in the period in which we make such determination.

A reconciliation of the beginning and ending amount of liabilities associated with uncertain tax positions is as follows:

	Year ended December 31,
	2022		2021
Balance - beginning of year	$	895	$	861
Additions based on tax positions related to the current year		75		61
Additions for tax positions of prior years		—		—
Reductions for tax positions of prior years		—		—
Settlements		—		(20	)
Lapse in statutes of limitations		(8)		(7	)
Uncertain tax positions, ending balance	$	962	$	895

The Company’s U.S. federal income tax returns for 2018 through 2022 are subject to examination. The Company's U.S. 2018 federal income tax return is currently under examination. The Company also files in various state and foreign jurisdictions. With few exceptions, the Company is no longer subject to federal, state, or non-U.S. income tax examinations by tax authorities for years prior to 2017.
