Business Description, Basis of Presentation and Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	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 company that designs, develops and sells conferencing, collaboration, streaming and digital signage solutions for audio and visual communications. The performance and simplicity of its advanced comprehensive solutions offer unprecedented levels of functionality, reliability and scalability.
	Basis of Presentation:
	Fiscal Year – This report on Form 10-K includes financial statements for the years ended December 31, 2014 and 2013.
	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. Certain prior year amounts have been reclassified to conform to the current year presentation.
	Use of Estimates – The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America 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 and product returns, provisions for obsolete inventory, valuation 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 Spain subsidiary, our foreign subsidiaries are U.S. dollar functional, for which gains and losses arising from remeasurement are included in earnings. Our Spain subsidiary is Euro 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 both the U.S. and 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 a portion 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.
	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 income/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.
	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, 2014 and 2013.
	Accounts Receivable – Accounts receivable are recorded at the invoiced amount. 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, 2014 and 2013 was as follows:
		Year ended December 31,
		2014			2013
	Balance at beginning of the year	$	129		$	60
	Allowance increase (decrease)	(49		)	96
	Write offs, net of recoveries	(22		)	(27		)
	Balance at end of the year	$	58		$	129
	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.
	Distributor channel inventories include products that have been delivered to customers for which revenue recognition criteria have not been met.
	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 $47 and $45, as of December 31, 2014 and 2013, respectively.
	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.
	Goodwill and Intangible Assets – Intangible assets acquired in a purchase business combination 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. Goodwill represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized. In accordance with the provisions of FASB ASC Topic 350, Intangibles – Goodwill and Other, the Company tests goodwill and other intangible assets with indefinite lives for impairment at least annually at the beginning of the fourth quarter, or sooner if a triggering event occurs suggesting possible impairment of the values of these assets. Impairment testing for these assets involves a two-step process. In the first step, the fair value of the reporting unit holding the assets is compared to its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of the impairment loss, if any. In the second step, the fair value of the reporting unit is allocated to all of its assets and liabilities, including intangible assets and liabilities not recorded on the balance sheet. The excess, if any, of the fair value of the reporting unit over the sum of the fair values allocated to identified assets and liabilities is the value of goodwill to be compared to its carrying value (See Note 3 – Business Combinations, Goodwill and Intangibles). ClearOne and all of its subsidiaries are considered as one reporting unit for this purpose.
	Impairment of Long-Lived Assets – Long-lived assets, such as property, equipment, and definite-lived intangibles 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.
	Revenue Recognition – Product revenue is recognized when (i) the products are shipped, (ii) persuasive evidence of an arrangement exists, (iii) the price is fixed and determinable, and (iv) collection is reasonably assured.
	The Company provides a right of return on product sales to certain distributors and other resellers under a product rotation program. Under this seldom-used program, once a quarter, a distributor or reseller is allowed to return products purchased during the prior 180 days for a total value generally not exceeding 15% of the distributor's or reseller’s net purchases during the preceding quarter. The distributor or reseller is, however, required to place a new purchase order for an amount not less than the value of products returned under the stock rotation program. When products are returned, the associated revenue, cost of goods sold, inventory and accounts receivable originally recorded are reversed. When the new order is fulfilled, the revenue, associated cost of goods sold, inventory and accounts receivable are recorded and the product revenue is subject to the deferral analysis described below. In a small number of cases, the distributors are also permitted to return products for other business reasons.
	Revenue from product sales to distributors is not recognized until the return privilege has expired or until it can be determined with reasonable certainty that the return privilege has expired, which approximates when product is sold-through to customers of the Company’s distributors (dealers, system integrators, value-added resellers, and end-users) rather than when the product is initially shipped to a distributor. At each quarter-end, the Company evaluates the inventory in the channel through information provided by our distributors. The level of inventory in the channel will fluctuate up-ward or down-ward each quarter, based upon its distributors’ individual operations. Accordingly, at each quarter-end, the deferral for revenue and associated cost of goods sold are calculated and recorded based upon the actual channel inventory reported at quarter-end. Further, with respect to distributors and other channel partners not reporting the channel inventory, the revenue and associated cost of goods sold are deferred until the Company receives payment for the product sales made to such distributors or channel partners.
	The amount of deferred cost of goods sold is included in distributor channel inventories.
	The details of deferred revenue and associated cost of goods sold and gross profit are as follows:
		As of December 31,
		2014			2013
	Deferred revenue	$	5,004		$	4,158
	Deferred cost of goods sold	1,698			1,520
	Deferred gross profit	$	3,306		$	2,638
	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, valued at retail price, until the defective unit has been returned, but no receivable balance is maintained on the Company’s balance sheet.
	Sales and Similar Taxes - Taxes collected from customers and remitted to government authorities are reported on a net basis and thus are excluded from revenues.
	Shipping and Handling Costs – Shipping and handling billed to customers is recorded as revenue. Shipping and handling costs are included in cost of goods sold.
	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,
		2014			2013
	Balance at the beginning of year	$	338		$	385
	Accruals/additions	511			433
	Usage/claims	(518		)	(480		)
	Balance at end of year	$	331		$	338
	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, 2014 and 2013 totaled $768 and $472, respectively, and are included under the caption “Sales and Marketing”.
	Research and Product Development Costs – The Company expenses research and product development costs as incurred.
	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. The Company evaluates the realizability of its net deferred tax assets on a quarterly basis and valuation allowances are provided, as necessary. Adjustments to the valuation allowance increase or decrease the Company’s income tax provision or benefit. As of December 31, 2014 and 2013, the Company had a valuation allowance of $786 and $378 against foreign net operating losses, and state research and development credits, respectively.
	The Company follows the provisions contained in ASC Topic 740, Income Taxes. The Company recognizes the tax benefit from an uncertain tax position only if it is at least more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.
	Judgment is required in determining the provision for income taxes and related accruals, deferred tax assets and liabilities. In the ordinary course of business, there are transactions and calculations where the ultimate tax outcome is uncertain. Additionally, the Company’s tax returns are subject to audit by various tax authorities. Although the Company believes that its estimates are reasonable, actual results could differ from these estimates.
	Earnings Per Share – The following table sets forth the computation of basic and diluted earnings per common share:
		Year ended December 31,
		2014			2013
	Numerator:
	Net income	$	5,596		$	5,179
	Denominator:
	Basic weighted average shares	9,166,769			9,064,340
	Dilutive common stock equivalents using treasury stock method	414,557			391,178
	Diluted weighted average shares	9,581,326			9,455,518
Basic earnings per common share:	$	0.61		$	0.57
Diluted earnings per common share:	$	0.58		$	0.55
Weighted average options outstanding	975,696			1,128,045
Anti-dilutive options not included in the computation	209,751			149,773
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.
Recent Accounting Pronouncements
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a full retrospective or retrospective with cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company on January 1, 2017. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.

	Acquisition of Sabine
	On March 7, 2014, the Company completed the acquisition of Sabine, Inc. ("Sabine") through a stock purchase agreement ("SPA"). Sabine manufactures, designs and sells Sacom professional wireless microphone systems for live and installed audio. It also makes FBX Feedback Exterminator for reliable automatic feedback control. With the addition of Sabine, ClearOne will have reliable and exclusive access to the wireless microphones that are a critical component of ClearOne’s complete microphone portfolio.
	Pursuant to the SPA, the Company (i) paid initial consideration of $8,141 in cash, (ii) accrued for possible additional earn-out payments over the next two years, estimated to be $657, and (iii) issued 150,000 shares of restricted common stock of the Company, valued at $1,679 (determined on the basis of the closing market price of the Company's stock on the acquisition date). The purchase price was paid out of cash on hand. The SPA contains representations, warranties and indemnifications customary for a transaction of this type.
	The following table summarizes the consideration paid for the acquisition:
		Consideration
	Cash	$	8,141
	Common stock	1,679
	Contingent consideration	657
	Total	$	10,477
	The fair values of Sabine assets acquired and liabilities assumed are based on the information that was available during the measurement period of twelve months from the date of acquisition. The fair value of identified assets and liabilities acquired and goodwill is as follows:
		Fair value
	Cash	$	125
	Accounts receivable	255
	Inventories	844
	Prepaid and other	105
	Intangibles	3,970
	Property and equipment	292
	Other long-term assets	11
	Goodwill	5,510
	Deferred tax asset	245
	Trade accounts payable	(420		)
	Accrued liabilities	(405		)
	Stock registration costs	(55		)
	Total	$	10,477
	The goodwill of $5,510 related to the acquisition of of Sabine is composed of expected synergies in utilizing Sabine technology in ClearOne product offerings, reduction in future combined research and development expenses, and intangible assets including acquired workforce that do not qualify for separate recognition. The goodwill balance of $5,510 related to the acquisition of Sabine is expected to be deductible for tax purposes.
	Supplemental Pro Forma Information:
	1) Revenue and net income from the Sabine business from March 8, 2014 to December 31, 2014 was $3,841 and $619 respectively.
	2) Revenue and earnings of the combined entity as though the business combination occurred as of January 1, 2013 were as follows:
		2014				2013

	Diluted earnings per common share	$	0.56			$	0.53
	3) There were no material, nonrecurring pro forma adjustments directly attributable to the acquisition included in this Supplemental Pro Forma Information.
	Spontania business of Spain-based Dialcom Networks, S.L.
	On April 1, 2014 ClearOne, Inc. closed on the acquisition of the Spontania business of Spain-based Dialcom Networks, S.L. The Spontania cloud-based service empowers customers to deploy HD video conferencing, web collaboration, and more with equipment most businesses have and use every day - video-conferencing endpoints, desktops, laptops, web browsers, tablets, and smartphones. With Spontania there is no hardware investment and the service operates off of a reservation-less model, enabling on-demand video communications from virtually anywhere, anytime, with anyone on any device.
	The aggregate purchase price under the terms of the transaction was approximately €3.66 million in cash (approximately US$5.1 million), after certain closing adjustments. ClearOne did not assume any debt or cash. The cash purchase price was paid out of cash on hand. The addition of this technology was an integral part of the company’s strategy to build an all-inclusive video collaboration portfolio.
	The fair value of identified assets and liabilities acquired from the Spontania acquisition was as follows:
		Fair value
	Intangibles	$	1,335
	Property and equipment	47
	Goodwill	3,741
	Accrued liabilities	(71		)
	Total	$	5,052
	The goodwill of $3,741 relates to the acquisition of Spontania cloud-based technology and intangible assets including acquired workforce that does not qualify for separate recognition. The goodwill of $3,741 from the Spontania acquisition is expected to be deductible for tax purposes.
	Supplemental Pro Forma Information:
	1) Revenue and net loss from the Spontania business from April 1, 2014 to December 31, 2014 was $753 and $1,629 respectively.
	2) Revenue and earnings of the combined entity as though the business combination occurred as of January 1, 2013 is not available. The Spontania business was part of a business unit of Dialcom Networks, S.L., and thus separate stand-alone financial information for Spontania is not available.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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 $3,830 as of December 31, 2014.
	Uncertain Tax Positions. As further discussed in Note 12, we had $1,678 of uncertain tax positions as of December 31, 2014. 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. In addition to the legal proceedings described below, we are also involved from time to time in various claims and other 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 proceedings will have a material adverse effect on our business, results of operations, financial position, or liquidity, except as described below.
	Former Officer Indemnification
	In July 2007 and January 2008, the U.S. Attorney for the District of Utah indicted two of our former officers, Frances Flood (“Flood”) and Susie Strohm (“Strohm”), for allegedly causing us to issue materially misstated financial statements for our 2001 and 2002 fiscal years and for perjury in connection with the investigation by the SEC into the alleged misstatements.  In December 2003, we entered into indemnification agreements with each former officer, requiring payment of all reasonable attorneys’ fees and costs incurred in defending against the charges in certain circumstances consistent with and subject to limitations imposed by our bylaws and applicable law.  In total, we paid approximately $3,630 in attorneys’ fees and costs to defend against the charges. In February 2009, Flood was convicted on nine counts and Strohm was convicted on one count. In June 2010, Flood was sentenced to four years in prison and three years of probation and Strohm was sentenced to two years of probation plus 150 hours of community service.  In April 2011, the Tenth Circuit Court of Appeals in Denver affirmed Flood’s conviction, but has allowed her to assert in a collateral proceeding her claim that she received ineffective assistance of counsel. In November 2011, the Tenth Circuit affirmed Strohm’s perjury conviction as well.
	Flood:  In August 2008, Flood filed a lawsuit in Federal District Court for the District of Utah, seeking to compel us to pay her attorneys’ fees and costs to defend against the criminal charges.  The District Court issued a preliminary injunction in January 2009 requiring us to pay Flood’s criminal legal fees and costs through trial.  Pursuant to the Court’s order, ClearOne paid approximately $373 to Flood’s attorneys and approximately $248 into the Court’s escrow. In July 2009, ClearOne asserted counterclaims against Flood and sought to recover $3,390 plus interest, costs and attorneys' fees.
	The Tenth Circuit Court of Appeals issued a ruling in August 2010 vacating the District Court’s preliminary injunction on the grounds that it rested on a legally erroneous interpretation of Flood’s Employment Separation Agreement.  ClearOne filed a motion in the United States District Court for the District of Utah seeking a return of the monies paid by ClearOne pursuant to the Court’s order. The District Court granted ClearOne’s motion in January 2012 for return of the $248 held in the Court’s escrow, but denied ClearOne’s motion with respect to the $373 paid to Flood’s attorneys.
	On or about March 1, 2013, Flood filed for personal bankruptcy in the U.S. Bankruptcy Court for the Eastern District of Virginia. On March 19, 2013, the US District Court for the District of Utah issued an order staying this case. On June 2, 2014, on the parties’ cross-motions for summary judgment, the bankruptcy judge ruled that Flood’s debt to ClearOne for the criminal defense fees advanced on her behalf is dischargeable in bankruptcy. On August 5, 2014, ClearOne and Flood entered into a settlement agreement whereby ClearOne released Flood from any claims in exchange for Flood’s release of ClearOne.
	Theft of Intellectual Property and Related Cases
	In January 2007, we filed a lawsuit in the Third Judicial District Court, Salt Lake County, Utah against WideBand Solutions, Inc. (“WideBand”) and two of its principals, Dr. Jun Yang, and Andrew Chiang for misappropriation of our trade secrets (the “Trade Secret Case”).  We also brought claims against Biamp Systems Corporation, Inc. (“Biamp”).  The litigation eventually included other defendants, namely Lonny Bowers, Donald Bowers, David Sullivan, Dial HD and Versatile DSP. The matter was subsequently removed to federal court. The United States District Court, District of Utah, Central Division.
	The litigation involved various appeals filed by all parties extended to various state courts, federal courts and the federal appeal court. The court found the defendants guilty of willfully and maliciously misappropriating our trade secrets. Various awards were made in ClearOne's favor and against the defendants. Biamp settled with us and paid $3,860 after we won the appeal in the Tenth Circuit court. We also settled with one of the defendants and received $250 in February 2012. We have various awards against other defendants amounting to approximately $7,658 owed jointly and severally by them. While we intend to vigorously pursue collection of these outstanding awards, there can be no assurance that we will ultimately collect on all or a portion of these awards.
	Conclusion
	These 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 the legal proceedings.
	The Company believes it is adequately accrued for the aforementioned contingent liabilities. While we intend to defend ourselves in the above matters vigorously and diligently, there exists the possibility of adverse outcomes that we estimate could be up to $1,000 over and above amounts already provided for. If these 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.

Shareholders' Equity and Share-based Payments [Abstract]
Share-Based Payments	Share-Based Payments
	The Company’s share-based compensation primarily consists of two share-based compensation plans, one which was replaced on November 20, 2007, and one which became active on the same date. The plans are described below.
	The Company’s 1998 Incentive Plan (the “1998 Plan”) had shares of common stock available for issuance to employees and directors. Through December 1999, 1,066,000 options were granted that would cliff vest after 9.8 years; however, such vesting was accelerated for 637,089 of these options upon meeting certain earnings per share goals through the fiscal year ended June 30, 2003. Subsequent to December 1999 and through June 2002, 1,248,250 options were granted that would cliff vest after 6.0 years; however, such vesting was accelerated for 300,494 of these options upon meeting certain earnings per share goals through the fiscal year ended June 30, 2005.
	The Company also has a 2007 Equity Incentive Plan (the “2007 Plan”). Provisions of the 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. Under both plans, one new share is issued for each stock option exercised.
	Of the options granted subsequent to June 2002, all vesting schedules 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. All options outstanding as of December 31, 2014 had contractual lives of ten years. Under the 1998 Plan, 2,500,000 shares were authorized for grant. As of December 31, 2014, there were 346,000 options outstanding under the 1998 Plan, which includes the cliff vesting and 3 or 4-year vesting options discussed above. As of December 31, 2014, there were 694,081 options outstanding under the 2007 Plan. As of December 31, 2014, the 2007 Plan had 95,915 authorized unissued options, while there were no options remaining that could be granted under the 1998 Plan.
	During 2014, the Company also had an Employee Stock Purchase Plan (“ESPP”) wherein employees could purchase common stock through payroll deductions of up to 10 percent of their base pay. Amounts deducted and accumulated by the employees were used to purchase shares of common stock on or about the first day of each month. The Company contributed to the account of the employee one share of common stock for every nine shares purchased by the employee under the ESPP. The details of the company's ESPP were modified for future periods.
	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.
	In applying the Black-Scholes methodology to the options granted, the Company used the following assumptions:
		Year ended December 31,
		2014		2013
	Risk-free interest rate, average	2.20%		1.80%
	Expected option life, average	8.2 years		6.8 years
	Expected price volatility, average	47.60%		49.80%
	Expected dividend yield	—%		—%
	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 compensation cost net of an expected forfeiture rate and recognized 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
	As of December 31, 2013	1,111,274			$	5.15
	Granted	193,500			8.83
	Expired and canceled	(29,532	)		6.87
	Forfeited prior to vesting	(729	)		8.88
	Exercised	(234,432	)		5.72
	As of December 31, 2014	1,040,081			$	5.65	5.6	$	4,286
	Vested and Expected to Vest at December 31, 2014	1,040,081			$	5.65	5.6	$	4,286
	Vested at December 31, 2014	730,016			$	4.67	4.15	$	3,721
	The weighted average per share fair value of options granted during the years ending December 31, 2014 and 2013 was $4.85 and $4.38 respectively. The total intrinsic value of options exercised during the years ended December 31, 2014 and 2013 was $1,337 and $489, respectively.
	The total pre-tax compensation cost related to stock options recognized during the years ended December 31, 2014 and 2013 was $401 and $296, respectively. Tax benefit from compensation cost related to stock options during the years ended December 31, 2014 and 2013 was $211 and $96, respectively. As of December 31, 2014, the total compensation cost related to stock options not yet recognized and before the effect of any forfeitures was $1,230, which is expected to be recognized over approximately the next 2.7 years on a straight-line basis.
	Stock Repurchase Program and Cash Dividends
	In May 2012, our Board of Directors authorized a stock repurchase program to purchase the Company's common stock in the open market. A total of 272,767 and 300,087 shares costing $2,598 and $2,416 were purchased under this program during the years ended December 31, 2014 and 2013. The cost of shares purchased is recorded as a reduction to shareholders' equity. On December 2, 2014, the Company announced the discontinuance of the stock repurchase program along with the initiation of a cash dividend plan. The first of such dividends was of $0.10 per share of ClearOne common stock, payable on January 5, 2015, to stockholders of record on December 12, 2014.

	Sales to significant customers that represented more than 10 percent of total revenues are as follows:
		Year ended December 31,
		2014			2013
	Customer A	16	%		18.2	%
	Customer B	—	%	*	10.8	%
	Total	16	%		29	%
	* Sales didn't exceed 10% of the revenue.
	The following table summarizes the percentage of total gross accounts receivable from significant customers:
		As of December 31,
		2014			2013
	Customer A	21	%		24.9	%
	Customer B	10	%		12.4	%
	Total	31	%		37.3	%
	These customers facilitate product sales to a large number of end-users, none of which is known to account for more than 10 percent of the Company’s revenue from product sales. Nevertheless, the loss of one or more of these customers could reduce revenue and have a material adverse effect on the Company’s business and results of operations.

Fair Value Measurements	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 substantial majority of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. The following tables set forth the fair value of the financial instruments re-measured by the Company as of December 31, 2014 and 2013:

	The Company has not provided for U.S. deferred income taxes or 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.
	In accordance with ASC Topic 740, the Company analyzed its valuation allowance at December 31, 2014 and determined that, based upon available evidence, it is more likely than not that certain of its deferred tax assets may not be realized and, as such, has established a valuation allowance against certain deferred tax assets.  These deferred tax assets include state research and development credits, and foreign net operating loss carryforwards.
	As of December 31, 2014, the Company had state research credit carryforwards of $60, which will begin to expire in 2027 if not utilized.  The Company has federal net operating loss (“NOL”) carryforwards of approximately $881 (pre-tax), Hong Kong NOL carryforwards of approximately $1,223, and Spain NOL carryforwards of approximately $1,820.  The federal NOL carryforwards will begin to expire in 2029. The Hong Kong and Spain NOL carryforwards do not expire.
	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, 2014 and 2013, that would favorably impact our effective tax rate if recognized was $723 and $623, respectively.   As of December 31, 2014 and 2013, we accrued $40 and $51, 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,
		2014			2013
	Balance - beginning of year	$	1,901		$	2,384
	Additions based on tax positions related to the current year	564			84
	Additions for tax positions of prior years	—			45
	Reductions for tax positions of prior years	(468		)	(518		)
	Settlements	(40		)	—
	Lapse in statutes of limitations	(279		)	(94		)
Uncertain tax positions, ending balance	$	1,678		$	1,901
The Company’s U.S. federal income tax returns for 2011 through 2013 are subject to 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 2011.  The Company completed its audit by the Internal Revenue Service (“IRS”) for its 2006 tax return in 2010.  As a result of the audit by the IRS, there were no material adjustments made to the Company’s tax return. The IRS commenced an examination of the Company's 2012 tax return. We do not anticipate the examination will result in a material change to its financial position.
The Inland Revenue Department of Hong Kong, a Special Administrative Region (the “IRD”), commenced an examination of the Company's Hong Kong profits tax returns for 2009 through 2011 in the fourth quarter of 2012 that is anticipated to be completed in 2015. The Company does not anticipate the examination will result in a material change to its financial position. During the next twelve months, it is reasonably possible that the amount of the Company's unrecognized income tax benefits could change significantly. These changes could be the result of our ongoing tax audits or the settlement of outstanding audit issues. However, due to the issues being examined, at the current time, an estimate of the range of reasonably possible outcomes cannot be made, beyond amounts currently accrued.

Business Description, Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Fiscal Year	Fiscal Year – This report on Form 10-K includes financial statements for the years ended December 31, 2014 and 2013.
Consolidation	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. Certain prior year amounts have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates – The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America 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 and product returns, provisions for obsolete inventory, valuation of long-lived assets, and deferred income tax asset valuation allowances. Actual results could differ materially from these estimates.
Foreign Currency Translation	Foreign Currency Translation – We are exposed to foreign currency exchange risk through our foreign subsidiaries. Other than our Spain subsidiary, our foreign subsidiaries are U.S. dollar functional, for which gains and losses arising from remeasurement are included in earnings. Our Spain subsidiary is Euro 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	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 both the U.S. and 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 a portion of our products.
Cash Equivalents	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.
Marketable Securities	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 income/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.
	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, 2014 and 2013.
Accounts Receivable	Accounts Receivable – Accounts receivable are recorded at the invoiced amount. 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.
Inventories	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.
	Distributor channel inventories include products that have been delivered to customers for which revenue recognition criteria have not been met.
	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 $47 and $45, as of December 31, 2014 and 2013, respectively.
Property and Equipment	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.
Goodwill and Intangible Assets	Goodwill and Intangible Assets – Intangible assets acquired in a purchase business combination 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. Goodwill represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized. In accordance with the provisions of FASB ASC Topic 350, Intangibles – Goodwill and Other, the Company tests goodwill and other intangible assets with indefinite lives for impairment at least annually at the beginning of the fourth quarter, or sooner if a triggering event occurs suggesting possible impairment of the values of these assets. Impairment testing for these assets involves a two-step process. In the first step, the fair value of the reporting unit holding the assets is compared to its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of the impairment loss, if any. In the second step, the fair value of the reporting unit is allocated to all of its assets and liabilities, including intangible assets and liabilities not recorded on the balance sheet. The excess, if any, of the fair value of the reporting unit over the sum of the fair values allocated to identified assets and liabilities is the value of goodwill to be compared to its carrying value (See Note 3 – Business Combinations, Goodwill and Intangibles). ClearOne and all of its subsidiaries are considered as one reporting unit for this purpose.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets – Long-lived assets, such as property, equipment, and definite-lived intangibles 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.
Revenue Recognition	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, valued at retail price, until the defective unit has been returned, but no receivable balance is maintained on the Company’s balance sheet.
	Revenue Recognition – Product revenue is recognized when (i) the products are shipped, (ii) persuasive evidence of an arrangement exists, (iii) the price is fixed and determinable, and (iv) collection is reasonably assured.
	The Company provides a right of return on product sales to certain distributors and other resellers under a product rotation program. Under this seldom-used program, once a quarter, a distributor or reseller is allowed to return products purchased during the prior 180 days for a total value generally not exceeding 15% of the distributor's or reseller’s net purchases during the preceding quarter. The distributor or reseller is, however, required to place a new purchase order for an amount not less than the value of products returned under the stock rotation program. When products are returned, the associated revenue, cost of goods sold, inventory and accounts receivable originally recorded are reversed. When the new order is fulfilled, the revenue, associated cost of goods sold, inventory and accounts receivable are recorded and the product revenue is subject to the deferral analysis described below. In a small number of cases, the distributors are also permitted to return products for other business reasons.
	Revenue from product sales to distributors is not recognized until the return privilege has expired or until it can be determined with reasonable certainty that the return privilege has expired, which approximates when product is sold-through to customers of the Company’s distributors (dealers, system integrators, value-added resellers, and end-users) rather than when the product is initially shipped to a distributor. At each quarter-end, the Company evaluates the inventory in the channel through information provided by our distributors. The level of inventory in the channel will fluctuate up-ward or down-ward each quarter, based upon its distributors’ individual operations. Accordingly, at each quarter-end, the deferral for revenue and associated cost of goods sold are calculated and recorded based upon the actual channel inventory reported at quarter-end. Further, with respect to distributors and other channel partners not reporting the channel inventory, the revenue and associated cost of goods sold are deferred until the Company receives payment for the product sales made to such distributors or channel partners.
	The amount of deferred cost of goods sold is included in distributor channel inventories.
Sales and Similar Taxes	Sales and Similar Taxes - Taxes collected from customers and remitted to government authorities are reported on a net basis and thus are excluded from revenues.
Shipping and Handling Costs	Shipping and Handling Costs – Shipping and handling billed to customers is recorded as revenue. Shipping and handling costs are included in cost of goods sold.
Warranty Costs	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.
Advertising	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, 2014 and 2013 totaled $768 and $472, respectively, and are included under the caption “Sales and Marketing”.
Research and Product Development Costs	Research and Product Development Costs – The Company expenses research and product development costs as incurred.
Income Taxes	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. The Company evaluates the realizability of its net deferred tax assets on a quarterly basis and valuation allowances are provided, as necessary. Adjustments to the valuation allowance increase or decrease the Company’s income tax provision or benefit. As of December 31, 2014 and 2013, the Company had a valuation allowance of $786 and $378 against foreign net operating losses, and state research and development credits, respectively.
	The Company follows the provisions contained in ASC Topic 740, Income Taxes. The Company recognizes the tax benefit from an uncertain tax position only if it is at least more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.
	Judgment is required in determining the provision for income taxes and related accruals, deferred tax assets and liabilities. In the ordinary course of business, there are transactions and calculations where the ultimate tax outcome is uncertain. Additionally, the Company’s tax returns are subject to audit by various tax authorities. Although the Company believes that its estimates are reasonable, actual results could differ from these estimates.
Share-Based Payment	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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a full retrospective or retrospective with cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company on January 1, 2017. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.
