Investments, Debt and Equity Securities [Abstract]

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 as of June 30, 2024 and December 31, 2023 were as follows:

Debt securities in an unrealized loss position as of June 30, 2024 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. The available-for-sale marketable securities with continuous gross unrealized loss position for less than 12 months and 12 months or greater and their related fair values were as follows:

	Less than 12 months					More than 12 months				Total

Business Description, Basis of Presentation and Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2024
Business Description, Basis of Presentation and Significant Accounting Policies
Basis of Presentation:	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 June 30, 2024 and December 31, 2023, the results of operations for the three and six months ended June 30, 2024 and 2023, and the cash flows for the six months ended June 30, 2024 and 2023. The results of operations for the three and six months ended June 30, 2024 and 2023 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, 2023 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, 2023. There have been no changes to these policies during the quarter ended June 30, 2024 that are of significance or potential significance to the Company. Recent accounting pronouncements: In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on the topic of income taxes. The standard requires additional disclosure for income taxes. These requirements include: (i) requiring a public entity to disclose specific categories in the rate reconciliation; (ii) disclosure of additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate); (iii) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; (iv) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received); (v) annual disclosure of income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign; and (vi) annual disclosure of income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. For public entities, the guidance is effective for annual periods beginning after December 15, 2024. The Company will adopt this guidance in fiscal 2025 and is in the process of evaluating the new requirements. As a result, the Company has not yet determined the impact this new ASU will have on its disclosures. The Company has determined that recently issued accounting standards, other than the above discussed, will not have a material impact on its consolidated financial position, results of operations or cash flows.
Liquidity:	Liquidity: As of June 30, 2024, our cash and cash equivalents were approximately $2,450 compared to $17,835 as of December 31, 2023. Our working capital was $21,707 as of June 30, 2024. Net cash used in operating activities was $2,722 for the six months ended June 30, 2024, a decrease of $55,642 compared to $52,920 of cash provided by operating activities for the six months ended June 30, 2023. The decrease in cash is mainly due to payment of dividends $14,490 in April 2024 and $28,979 in May 2023.These conditions raise substantial doubt about continuing as a going concern, but substantial doubt is alleviated because the Company believes, although there can be no assurance, that the current cash position and effective management of working capital, will provide the liquidity needed to meet our operating needs through at least August 14, 2025. The Company also believes that its strong portfolio of intellectual property and its solid brand equity in the market will enable it to raise additional capital if and when needed to meet its short and long-term financing needs; however, there can be no assurance that, if needed, the Company will be successful in obtaining the necessary funds through equity or debt financing on favorable terms or at all. If the Company needs additional capital and is unable to secure financing, it may be required to further reduce expenses, or delay product development and enhancement.

9. Share-based Compensation

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.

A summary of the stock option activity under the Company’s plans for the six months ended June 30, 2024, is as follows:

	Number of shares			Weighted average exercise price
Options outstanding at beginning of year		607,810		$	5.03
Granted		—			—
Less:
Exercised		—			—
Forfeited prior to vesting		(20,000	)		—

As of June 30, 2024, the total remaining unrecognized compensation cost related to non-vested stock options, net of forfeitures, was approximately $97, which will be recognized over a weighted average period of 2.21 years.

Fair Value Measurements

Fair Value Measurements

11. 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 June 30, 2024:

	Level 1		Level 2		Level 3		Total
June 30, 2024
Mutual funds	$	1,550	$	—	$	—	$	1,550

The performance and simplicity of our advanced, comprehensive solutions offer unprecedented levels of functionality, reliability and scalability.

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 June 30, 2024 and December 31, 2023, the results of operations for the three and six months ended June 30, 2024 and 2023, and the cash flows for the six months ended June 30, 2024 and 2023. The results of operations for the three and six months ended June 30, 2024 and 2023 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, 2023 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, 2023. There have been no changes to these policies during the quarter ended June 30, 2024 that are of significance or potential significance to the Company.

Recent accounting pronouncements:

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on the topic of income taxes. The standard requires additional disclosure for income taxes. These requirements include: (i) requiring a public entity to disclose specific categories in the rate reconciliation; (ii) disclosure of additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate); (iii) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; (iv) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received); (v) annual disclosure of income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign; and (vi) annual disclosure of income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. For public entities, the guidance is effective for annual periods beginning after December 15, 2024. The Company will adopt this guidance in fiscal 2025 and is in the process of evaluating the new requirements. As a result, the Company has not yet determined the impact this new ASU will have on its disclosures.

The Company has determined that recently issued accounting standards, other than the above discussed, will not have a material impact on its consolidated financial position, results of operations or cash flows.

Liquidity:

As of June 30, 2024, our cash and cash equivalents were approximately $2,450 compared to $17,835 as of December 31, 2023. Our working capital was $21,707 as of June 30, 2024. Net cash used in operating activities was $2,722 for the six months ended June 30, 2024, a decrease of $55,642 compared to $52,920 of cash provided by operating activities for the six months ended June 30, 2023. The decrease in cash is mainly due to payment of dividends $14,490 in April 2024 and $28,979 in May 2023.These conditions raise substantial doubt about continuing as a going concern, but substantial doubt is alleviated because the Company believes, although there can be no assurance, that the current cash position and effective management of working capital, will provide the liquidity needed to meet our operating needs through at least August 14, 2025. The Company also believes that its strong portfolio of intellectual property and its solid brand equity in the market will enable it to raise additional capital if and when needed to meet its short and long-term financing needs; however, there can be no assurance that, if needed, the Company will be successful in obtaining the necessary funds through equity or debt financing on favorable terms or at all. If the Company needs additional capital and is unable to secure financing, it may be required to further reduce expenses, or delay product development and enhancement.

Income Taxes

10. Income Taxes

The Company recorded a full valuation allowance against U.S Federal and State deferred tax assets, which results in no income tax benefit for losses in these jurisdictions. The full domestic valuation allowance was recorded as management concluded that it is more likely than not that these deferred tax assets are not realizable due to the Company's recent pre-tax losses and other sources of negative evidence. Provision for income taxes for the six months ended June 30, 2024 mostly represents income tax expense (benefit) recorded for jurisdictions outside the United States.

The Company had approximately $1,079 of uncertain tax positions as of June 30, 2024. Due to the inherent uncertainty of the underlying tax positions, it is not possible to forecast the payment of this liability for any particular year, therefore, it is reflected in other long-term liabilities.

- Definition

The entire disclosure for income tax.

Loss Per Share

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 the convertible portion of senior convertible notes are considered to be potential common stock. The computation of diluted loss per share does not assume exercise or conversion of securities that would have an anti-dilutive effect.

Basic loss per common share is the amount of net loss for the period available to each weighted-average share of common stock outstanding during the reporting period. Diluted loss per common share is the amount of 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 loss per common share:
