Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 Company that designs, develops and sells conferencing, collaboration, network streaming and digital signage solutions for audio and visual communications. The performance and simplicity of our advanced comprehensive solutions offer unprecedented levels of functionality, reliability, and scalability.

Basis of Presentation:

Fiscal Year – This report on Form 10-K includes consolidated balance sheets for the years ended December 31, 2016 and 2015 and the related consolidated statements of income and comprehensive income, cash flows, and shareholders’ equity for each of the years 2016, 2015 and 2014.

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 accounting principles generally accepted 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, potential impairment of goodwill and 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 (except digital signage 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 shareholders’ equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Dividend and interest income are recognized when earned.

A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and establishes a new cost basis for the security. Losses are charged against “Other income” when a decline in fair value is determined to be other than temporary. We review several factors to determine whether a loss is other than temporary. These factors include, but are not limited to: (i) the extent to which the fair value is less than cost and the cause for the fair value decline, (ii) the financial condition and near term prospects of the issuer, (iii) the length of time a security is in an unrealized loss position and (iv) our ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. There were no other-than-temporary impairments recognized during the years ended December 31, 2016, 2015 and 2014.

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 as follows:

	Year Ended December 31,
	2016			2015			2014
Balance at beginning of the year	$	54		$	58		$	129
Allowance increase (decrease)		148			36			(49	)
Write offs, net of recoveries		(15	)		(40	)		(22	)
Balance at end of the year	$	187		$	54		$	58

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 $21 and $75, as of December 31, 2016 and 2015, 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,
	2016		2015
Deferred revenue	$	3,882	$	4,549
Deferred cost of goods sold		1,530		1,628
Deferred gross profit	$	2,352	$	2,921

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

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

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,
	2016			2015			2014
Balance at the beginning of year	$	288		$	331		$	338
Accruals/additions		361			442			511
Usage/claims		(403	)		(485	)		(518	)
Balance at end of year	$	246		$	288		$	331

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, 2016, 2015 and 2014 totaled $836, $728, and $768, 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, 2016 and 2015, the Company had a valuation allowance of $1,404 and $1,071, respectively against foreign net operating losses, foreign intangible assets, capital losses carryforwards, and state research and development credits.

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 – 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 2015, 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 permitted. The updated standard becomes effective for the Company on January 1, 2018. The Company expects to adopt this accounting standard update on a modified retrospective basis in the first quarter of fiscal 2019, and it is currently evaluating the impact of this accounting standard update on the consolidated financial statements.

On February 25, 2016, FASB released Accounting Standards Update No. 2016-02, Leases (Topic 842) to bring transparency to lessee balance sheets. The ASU will require organizations that lease assets (lessees) to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The standard will apply to both types of leases-capital (or finance) leases and operating leases. Previously, GAAP has required only capital leases to be recognized on lessee balance sheets. The standard will take effect the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early application will be permitted for all organizations. 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.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation: Improvements to Employee Shared-Based Payment Accounting. The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for the Company on January 1, 2017 and it is currently evaluating the impact that ASU 2016-09 will have on our consolidated financial statements.

2. 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 shareholders’ equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Dividend and interest income are recognized when earned.

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 security at December 31, 2016 and 2015 were as follows:

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 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.

Spontania business of Spain-based Dialcom Networks, S.L.

On April 1, 2014 ClearOne 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.

Commitments and Contingencies

8. Commitments and Contingencies

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

Outsource Manufacturers. We have manufacturing agreements with electronics manufacturing service (“EMS”) providers related to the outsourced manufacturing of our products. Certain manufacturing agreements establish annual volume commitments. We are also obligated to repurchase Company-forecasted but unused materials. The Company has non-cancellable, non-returnable, and long-lead time commitments with its EMS providers and certain suppliers for inventory components that will be used in production. The Company’s purchase commitments under such agreements is approximately $13,563 as of December 31, 2016.

Uncertain Tax Positions. As further discussed in Note 12, we had $1,189 of uncertain tax positions as of December 31, 2016. 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.

On or about October 24, 2016, the Company received written notice from the United States Department of Labor, Occupational Health and Safety Administration (“OSHA”) that a complaint had been filed against it by a former employee. Among other things, the former employee’s OSHA complaint alleges harassment, retaliation, and violations of 18 U.S.C.A. Section 1514A, et seq. (the “Sarbanes-Oxley Act”) arising out of the termination of his employment with the Company on or about August 17, 2016 (the “OSHA Complaint”). The Company denies the allegations in the OSHA complaint, has not discovered any evidence of wrongdoing with respect to the allegations previously made by the former employee, and is vigorously defending the claims. On March 2, 2017, the Company received notice that the same former employee who initiated the OSHA Complaint also has filed a complaint with the Utah Labor Commission, Anti-Discrimination& Labor Division (the “Utah Complaint”) alleging that the employee's termination was discriminatory based upon a disability or, in the alternative, retaliatory for substantially the same reasons alleged in the OSHA Complaint. The Company is in the process of assessing the Utah Complaint and intends to vigorously defend it.

In 2016, the Company recorded $927 of pretax gross expenses related to the defense of the OSHA Complaint and review of the allegations underlying the former employee’s OSHA complaint.

We expect to incur additional expenses related to legal and other professional services rendered in connection with the defense of OSHA Complaint and/or related matters in future periods and will recognize these expenses as services are received. Expenses related to the defense of the OSHA Complaint and/or related matters may include additional liabilities from OSHA’s expected investigation; future governmental investigations and/or enforcement proceedings; future civil litigation; and future unspecified expenses.

The Company maintains an Employment Practices Liability policy with Chubb/Federal Insurance Company (the “EPL Policy”). Based on the allegations contained in the OSHA Complaint, the Company has tendered a claim for coverage under the EPL Policy.

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

Conclusion

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

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

Employee Stock Option Plans

The Company’s share-based incentive plans offering stock options primarily consists of two plans. Under both plans, one new share is issued for each stock option exercised. The plans are described below.

The Company’s 1998 Incentive Plan (the “1998 Plan”) was the Company’s primary plan through November 2007. Under this plan shares of common stock was made 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’s 2007 Equity Incentive Plan (the “2007 Plan”) was restated and approved by the shareholders on December 12, 2015. Provisions of the restated 2007 Plan include the granting of up to 2,000,000 incentive and non-qualified stock options, stock appreciation rights, restricted stock and restricted stock units. Options may be granted to employees, officers, non-employee directors and other service providers and may be granted upon such terms as the Compensation Committee of the Board of Directors determines in their sole discretion.

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, 2016 had contractual lives of ten years.

Under the 1998 Plan, 2,500,000 shares were authorized for grant. As of December 31, 2016, there were 150,000 options outstanding under the 1998 Plan, which includes the cliff vesting and 3 or 4-year vesting options discussed above.

As of December 31, 2016, there were 700,232 options outstanding under the 2007 Plan. As of December 31, 2016, the 2007 Plan had 826,268 authorized unissued options, while there were no options remaining that could be granted under the 1998 Plan.

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,
	2016			2015			2014
Risk-free interest rate, average		1.52	%		2.00	%		2.20	%
Expected option life, average		6.1 years			6.1 years			8.2 years
Expected price volatility, average		43.75	%		44.30	%		47.60	%
Expected dividend yield		1.71	%		1.10	%		-%

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:

The weighted average per share fair value of options granted during the years ending December 31, 2016, 2015 and 2014 was $4.27, $5.27, and $ 4.85 respectively. The total intrinsic value of options exercised during the years ended December 31, 2016, 2015 and 2014 was $2,824, $404, and $1,337 respectively.

The total pre-tax compensation cost related to stock options recognized during the years ended December 31, 2016, 2015, and 2014 was $628, $552 and $401, respectively. Tax benefit from compensation cost related to stock options during the years ended December 31, 2016, 2015 and 2014 was $107, $41 and $211, respectively. As of December 31, 2016, the total compensation cost related to stock options not yet recognized and before the effect of any forfeitures was $1,127, which is expected to be recognized over approximately the next 2.19 years on a straight-line basis.

Employee Stock Purchase Plan

During 2016, the Company issued shares to employees under the Company’s 2015 Employee Stock Purchase Plan (the “ESPP”). The ESPP was approved by the Company’s shareholders on December 12, 2015. As of December 31, 2016, 475,893 of the originally approved 500,000 shares were available for offerings under the ESPP. Offering periods under the ESPP commence on each Jan 1 and July 1, and continue for a duration of six months. The ESPP is available to all employees who do not own, or are deemed to own, shares of stock making up an excess of 5% of the combined voting power of the Company, its parent or subsidiary.

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

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 shares costing $2,598 were purchased under this program during the year ended December 31, 2014. The cost of shares purchased were recorded as a reduction to shareholders’ equity. On December 2, 2015, the Company announced the discontinuance of the stock repurchase program along with the initiation of a cash dividend plan. On January 31, 2017, the Company declared its most recent dividend under this plan of $0.05 per share of ClearOne common stock, payable on March 1, 2017 to shareholders of record on February 15, 2017. In addition, on March 1, 2017, our Board of Directors authorized an increase in our quarterly dividend from $0.05 per share to $0.07 per share beginning with the second quarter dividend in 2017 expected to be paid on or about June 1, 2017.

On March 9, 2016, the Board of Directors of the Company authorized the repurchase of up to $10,000 of the Company’s outstanding shares of common stock under a new stock repurchase program. In connection with the repurchase authorization, the Company was authorized to complete the repurchase through open market transactions or through an accelerated share repurchase program, in each case to be executed at management’s discretion based on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. The repurchase program may be suspended or discontinued at any time without prior notice. The transactions effectuated to date occurred in open market purchases.

On March 1, 2017, the Board of Directors of the Company renewed and extended the repurchase program for up to an additional $10 million of common stock over the next twelve months. In connection with the repurchase extension authorization, the Company was authorized to complete the repurchase through open market transactions or through an accelerated share repurchase program, in each case to be executed at management’s discretion based on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. The repurchase program may be suspended or discontinued at any time without prior notice. The transactions effectuated to date occurred in open market purchases.

During the twelve months ended December 31, 2016, we acquired the following shares of common stock under the current stock repurchase program:

$ in thousands except per share price	Total Number of Shares Purchased (a)		Average Price Paid per Share (b)		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs (c)		Approximate Dollar Value of Shares that May Yet Be Purchased Under the Plans or Programs ($ thousands) (d)

Total		542,259	$	11.25		542,259

From March 11, 2016 to March 17, 2016, the Company offered to repurchase eligible vested options to purchase shares under the 1998 Plan and the 2007 Plan from employees and directors. The Company repurchased delivered options at a repurchase price equal to the difference between the closing market price on the date of the employee’s communication of accepting the repurchase offer and the exercise price of such employee’s delivered options, subject to applicable withholding taxes and charges. The Company repurchased 225,542 stock options from employees and directors at an average purchase price of $7.77.

Fair Value Disclosures [Abstract]

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 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, 2016 and 2015:

	Level 1		Level 2		Level 3		Total

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, 2016 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 foreign net operating loss carryforwards, foreign intangible assets, state R&D tax credit carryforwards, and capital loss carryforwards.

The Company has federal net operating loss (“NOL”) carryforwards of approximately $755 (pre-tax), Hong Kong NOL carryforwards of approximately $255, and Spain NOL carryforwards of approximately $855. 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, 2016 and 2015, that would favorably impact our effective tax rate if recognized was $233 and $176, respectively. As of December 31, 2016 and 2015, we accrued $87 and $55, 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,
	2016		2015
Balance - beginning of year	$	1,126	$	1,678
Additions based on tax positions related to the current year		16		52
Additions for tax positions of prior years		47		5
Reductions for tax positions of prior years		-		(503	)
Settlements		-		—
Lapse in statutes of limitations		-		(106	)
Uncertain tax positions, ending balance	$	1,189	$	1,126

The Company’s U.S. federal income tax returns for 2012 through 2015 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 2012. 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, which was completed subsequent to December 31, 2016. As a result of the audit, there were no material changes to the Company’s 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.
