Business Description, Basis of Presentation and Significant Accounting Policies

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 AV streaming solutions for voice and visual communications. The performance and simplicity of our advanced, comprehensive solutions offer unprecedented levels of functionality, reliability and scalability.

Basis of Presentation:

The fiscal year for ClearOne is the twelve months ending on December 31. The condensed consolidated financial statements include the accounts of ClearOne and its subsidiaries. All significant inter-company accounts and transactions have been eliminated.

These accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and are not audited. Certain information and footnote disclosures that are usually included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been either condensed or omitted in accordance with SEC rules and regulations. The accompanying condensed consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of September 30, 2021 and December 31, 2020, the results of operations for the three and nine months ended September 30, 2021 and 2020, and the cash flows for the nine months ended September 30, 2021 and 2020. The results of operations for the three and nine months ended September 30, 2021 and 2020 are not necessarily indicative of the results for a full-year period. These interim unaudited condensed consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC.

Significant Accounting Policies:

The significant accounting policies were described in Note 1 to the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2020. There have been no changes to these policies during the nine months ended September 30, 2021 that are of significance or potential significance to the Company.

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

Liquidity:

As of September 30, 2021, our cash and cash equivalents were approximately $9,161 compared to $3,803 as of December 31, 2020. Our working capital was $23,739 as of September 30, 2021. Net cash used in operating activities was $1,477 for the nine months ended September 30, 2021, an increase of $1,168 from $309 of cash used in activities in the nine months ended September 30, 2021.

We are currently pursuing all available legal remedies to defend our strategic patents from infringement. We have already spent approximately $25,668 from 2016 through September 30, 2021 towards this litigation and may be required to spend more to continue our legal defense. We believe the decision by the U.S. District Court in August 2019 granting our request for a preliminary injunction to prevent our competitor from manufacturing, marketing, and selling its competing ceiling microphone array in an infringing configuration is an incredibly valuable ruling for ClearOne and its business. We believe that the decision validates the strength and importance of ClearOne’s intellectual property rights, recognizes ClearOne’s innovations in this space, and stops our competitor from further infringing our Graham patent (U.S. Patent No. 9,813,806) pending a full trial. Although there can be no assurance of any outcome of a full trial, we believe this ruling will help pave the way for ClearOne’s recovery from the immense harm inflicted by our competitor's infringement of our valuable patents. For more information about our intellectual property litigation, See Note 8. Commitments and Contingencies - Legal Proceedings, in our annual report on Form 10-K for the year ended December 31, 2020 and Part II, Item 1. Legal Proceedings in this quarterly report.

We have been actively engaged in preserving cash by suspending our dividend program and allowing our share repurchase program to expire in 2018 and implementing company-wide cost reduction measures. We have also 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 addition, we have been generating additional cash as our inventory levels are brought down to historical levels.

We also believe that the measures taken by us will yield higher revenues in the future. We believe, although there can be no assurance, that all of these measures and effective management of working capital will provide the liquidity needed to meet our operating needs through at least November 12, 2022. We also believe that our strong portfolio of intellectual property and our solid brand equity in the market will enable us to raise additional capital if and when needed to meet our short and long-term financing needs; however, there can be no assurance that, if needed, we will be successful in obtaining the necessary funds through equity or debt financing. If we need additional capital and are unable to secure financing, we may be required to further reduce expenses, delay product development and enhancement, or revise our strategy regarding ongoing litigation.

Earnings (Loss) Per Share

Earnings (Loss) Per Share

3. Loss Per Share

Loss per common share is computed based on the weighted-average number of common shares outstanding and, when appropriate, dilutive potential common stock outstanding during the period. Stock options, warrants and convertible portion of senior convertible notes are considered to be potential common stock. The computation of diluted earnings (loss) per share does not assume exercise or conversion of securities that would have an anti-dilutive effect.

Basic earnings (loss) per common share is the amount of net earnings (loss) for the period available to each weighted-average share of common stock outstanding during the reporting period. Diluted earnings (loss) per common share is the amount of earnings (loss) for the period available to each weighted-average share of common stock outstanding during the reporting period and to each share of potential common stock outstanding during the period, unless inclusion of potential common stock would have an anti-dilutive effect.

The following table sets forth the computation of basic and diluted earnings (loss) per common share:

	Three months ended September 30,						Nine months ended September 30,
	2021			2020			2021			2020

4. Marketable Securities

The Company has classified its marketable securities as available-for-sale securities. These securities are carried at estimated fair value with unrealized holding gains and losses included in accumulated other comprehensive loss in stockholders’ 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.

The amortized cost, gross unrealized holding gains, gross unrealized holding losses, and fair value for available-for-sale securities by major security type and class of securities at September 30, 2021 and December 31, 2020 were as follows:

	Amortized cost		Gross unrealized holding gains		Gross unrealized holding losses		Estimated fair value
September 30, 2021
Available-for-sale securities:
Corporate bonds and notes	$	808	$	11	$	—	$	819
Municipal bonds		600		1		—		601
Total available-for-sale securities	$	1,408	$	12	$	—	$	1,420

December 31, 2020
Available-for-sale securities:
Corporate bonds and notes	$	1,312	$	26	$	—	$	1,338
Municipal bonds		1,536		5		—		1,541
Total available-for-sale securities	$	2,848	$	31	$	—	$	2,879

Maturities of marketable securities classified as available-for-sale securities were as follows at September 30, 2021:

	Amortized cost		Estimated fair value
Due within one year	$	705	$	713
Due after one year through five years		703		707
Due after five years		—		—
Total available-for-sale securities	$	1,408	$	1,420

Debt securities in an unrealized loss position as of September 30, 2021 were not deemed impaired at acquisition and subsequent declines in fair value are not deemed attributed to declines in credit quality. Management believes that it is more likely than not that the securities will receive a full recovery of par value, although there can be no assurance that such recovery will occur.

There were no available-for-sale marketable securities with gross unrealized loss positions.

9. Debt

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 at the time that the Notes and Warrants were issued to him.

The Notes will mature on December 17, 2023 (the “Maturity Date”) and will 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:

	September 30, 2021			December 31, 2020
Liability component:
Principal	$	2,730		$	3,000
Less: debt discount and issuance costs, net of amortization		(434	)		(581	)
Net carrying amount	$	2,296		$	2,419
Equity component⁽¹⁾:
Warrants	$	318		$	318
Conversion feature		122			122
Net carrying amount	$	440		$	440

Current portion of liability component included under short-term debt	$	630		$	360
Long-term portion of liability component included under long-term debt		1,666			2,059
Liability component total	$	2,296		$	2,419

(1) Recorded on the condensed 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 three and nine months ended September 30, 2021, amortization of debt discount and issuance costs was $49 and $147, respectively and for the three and nine months ended September 30, 2020, amortization of debt discount and issuance costs was $50 and $148, respectively. The following table represents schedule of maturities of principal amount contained in the Notes as of September 30, 2021:

Year ending December 31,	Principal Amount Maturing
2021 (Remainder)	$	90
2022		720
2023		1,920
2024		—
Total principal amount	$	2,730

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 “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 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.

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 has 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 PPP Loan may be prepaid at any time prior to maturity with no prepayment penalties. The PPP Loan contains events of default and other provisions customary for a loan of this type. The Paycheck Protection Program provides that the Loans may be partially or wholly forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. The Company intends to use the entire PPP Loan amount for qualifying expenses and to apply for forgiveness of the PPP Loan in accordance with the terms of the CARES Act.

	September 30, 2021		December 31, 2020
Current portion of the PPP Loan included under short-term debt	$	874	$	312
Long-term portion of the PPP Loan included under long-term debt		625		1,187

Fair Value Measurements

Fair Value Measurements

10. Fair Value Measurements

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 Company’s financial instruments are valued using observable inputs. The following table sets forth the fair value of the financial instruments re-measured by the Company as of September 30, 2021 and December 31, 2020:

	Level 1		Level 2		Level 3		Total
September 30, 2021

Income Taxes

11. Income Taxes

The current year loss did not result in income tax benefit due to recording a full valuation allowance against expected benefits. The valuation allowance was recorded as we concluded that it was more likely than not that our deferred tax assets were not realizable primarily due to the Company's recent pre-tax losses. Provision for income taxes for the nine months ended September 30, 2021 represents income tax expense recorded for jurisdictions outside the United States.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

These accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and are not audited. Certain information and footnote disclosures that are usually included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been either condensed or omitted in accordance with SEC rules and regulations. The accompanying condensed consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of September 30, 2021 and December 31, 2020, the results of operations for the three and nine months ended September 30, 2021 and 2020, and the cash flows for the nine months ended September 30, 2021 and 2020. The results of operations for the three and nine months ended September 30, 2021 and 2020 are not necessarily indicative of the results for a full-year period. These interim unaudited condensed consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC.
Significant Accounting Policies:	Significant Accounting Policies: The significant accounting policies were described in Note 1 to the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2020. There have been no changes to these policies during the nine months ended September 30, 2021 that are of significance or potential significance to the Company. Recent accounting pronouncements: The Company has determined that recently issued accounting standards will not have a material impact on its consolidated financial position, results of operations or cash flows.
Liquidity:	Liquidity: As of September 30, 2021, our cash and cash equivalents were approximately $9,161 compared to $3,803 as of December 31, 2020. Our working capital was $23,739 as of September 30, 2021. Net cash used in operating activities was $1,477 for the nine months ended September 30, 2021, an increase of $1,168 from $309 of cash used in activities in the nine months ended September 30, 2021. We are currently pursuing all available legal remedies to defend our strategic patents from infringement. We have already spent approximately $25,668 from 2016 through September 30, 2021 towards this litigation and may be required to spend more to continue our legal defense. We believe the decision by the U.S. District Court in August 2019 granting our request for a preliminary injunction to prevent our competitor from manufacturing, marketing, and selling its competing ceiling microphone array in an infringing configuration is an incredibly valuable ruling for ClearOne and its business. We believe that the decision validates the strength and importance of ClearOne’s intellectual property rights, recognizes ClearOne’s innovations in this space, and stops our competitor from further infringing our Graham patent (U.S. Patent No. 9,813,806) pending a full trial. Although there can be no assurance of any outcome of a full trial, we believe this ruling will help pave the way for ClearOne’s recovery from the immense harm inflicted by our competitor's infringement of our valuable patents. For more information about our intellectual property litigation, See Note 8. Commitments and Contingencies - Legal Proceedings, in our annual report on Form 10-K for the year ended December 31, 2020 and Part II, Item 1. Legal Proceedings in this quarterly report. We have been actively engaged in preserving cash by suspending our dividend program and allowing our share repurchase program to expire in 2018 and implementing company-wide cost reduction measures. We have also 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 addition, we have been generating additional cash as our inventory levels are brought down to historical levels. We also believe that the measures taken by us will yield higher revenues in the future. We believe, although there can be no assurance, that all of these measures and effective management of working capital will provide the liquidity needed to meet our operating needs through at least November 12, 2022. We also believe that our strong portfolio of intellectual property and our solid brand equity in the market will enable us to raise additional capital if and when needed to meet our short and long-term financing needs; however, there can be no assurance that, if needed, we will be successful in obtaining the necessary funds through equity or debt financing. If we need additional capital and are unable to secure financing, we may be required to further reduce expenses, delay product development and enhancement, or revise our strategy regarding ongoing litigation.
