Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Description of Business and Summary of Significant Accounting Policies | 1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of the Business Basis of Presentation The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the audited financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC. Principles of Consolidation Cash and Cash Equivalents Investments Revenue Recognition Pursuant to the Company’s standard terms of sale, revenue is recognized when title to the goods and risk of loss transfers to customers and there are no remaining obligations that will affect the customers’ final acceptance of the sale. Generally, the Company’s standard terms of sale define the transfer of title and risk of loss to occur upon shipment to the respective customer. The Company generally does not maintain any post-shipping obligations to the recipients of the products. No installation, calibration or testing of this equipment is performed by the Company subsequent to shipment to the customer in order to render it operational. Revenue includes shipping and handling revenue of $271 and $236 for the three months ended June 30, 2015 and 2014, respectively, and $518 and $463 for the six months ended June 30, 2015 and 2014, respectively. Cost of freight for shipments made to customers is included in cost of revenue. Sales and other value-added taxes collected from customers and remitted to governmental authorities are excluded from revenue. The Company sells its products primarily through a direct sales force, with certain international markets sold through distributors. Terms of sale are generally consistent for both end-users and distributors except that payment terms are generally net 30 days for end-users and net 60 days for distributors. Sales Returns and Allowances Allowance for Doubtful Accounts Receivable Inventories Inventories consist of the following: June 30, 2015 December 31, Raw materials $ 5,286 $ 4,429 Work in process 1,251 1,397 Finished goods 9,536 8,431 Inventories $ 16,073 $ 14,257 Property and Equipment Generators and other capital equipment (such as the Company’s switchbox units and cryosurgical consoles) are loaned at no cost to direct customers that use the Company’s disposable products. Depreciation of such assets is included in cost of revenue. The estimated useful lives of this equipment are based on anticipated usage by customers and the timing and impact of expected new technology rollouts by the Company. To the extent the Company experiences changes in the usage of this equipment or introduces new technologies, the estimated useful lives of this equipment may change in a future period. Depreciation related to these generators was $673 and $498 for the three months ended June 30, 2015 and 2014, respectively, and $1,293 and $959 for the six months ended June 30, 2015 and 2014, respectively. As of June 30, 2015 and December 31, 2014, the net carrying amount of loaned equipment included in net property and equipment in the Condensed Consolidated Balance Sheets was $4,799 and $4,141, respectively. The Company reviews property and equipment for impairment using its best estimates based on reasonable and supportable assumptions and projections. Intangible Assets Goodwill— Other Current Liabilities and Current Maturities of Capital Leases— Other Income The Company recorded net foreign currency transaction (losses) gains of ($46) and $16 for the three months ended June 30, 2015 and 2014, respectively, and ($209) and $21 for the six months ended June 30, 2015 and 2014, respectively, primarily in connection with settlements of its intercompany balance with AtriCure Europe. The Company periodically is awarded grants to support research and development activities or education activities. The Company recognizes grant income when the funds are earned. The Company recorded grant income of $0 and $137 during the three months ended June 30, 2015 and 2014, respectively. Grant income of $35 and $500 was recorded for the six month periods ended June 30, 2015 and 2014, respectively. The Company historically issued stock options to non-employee consultants as a form of compensation for services provided to the Company. Because the non-employee options require settlement by the Company’s delivery of registered shares and because the tax withholding provisions in the awards allow the options to be partially net-cash settled, these options, when vested, are no longer eligible for equity classification and are, thus, subsequently accounted for as derivative liabilities under FASB ASC 815, “Derivatives and Hedging” (ASC 815) until the awards are ultimately either exercised or forfeited. Accordingly, the vested non-employee options are classified as liabilities and remeasured at fair value through earnings at each reporting period. During the three months ended June 30, 2015 and 2014, $44 and ($19), respectively, of expense (income) was recorded as a result of the remeasurement of the fair value of these fully vested stock options. During the six months ended June 30, 2015 and 2014, $57 and ($117), respectively, of expense (income) was recorded as a result of the remeasurement of the fair value of these fully vested stock options. Taxes The Company’s estimate of the valuation allowance for deferred tax assets requires it to make significant estimates and judgments about its future operating results. Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred tax assets on a quarterly basis to determine if valuation allowances are required by considering all available evidence. Deferred tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable income, exclusive of reversing temporary differences and carryforwards, taxable income in carry-back years and tax planning strategies that are both prudent and feasible. In evaluating whether to record a valuation allowance, the applicable accounting standards deem that the existence of cumulative losses in recent years is a significant piece of objectively verifiable negative evidence that must be overcome by objectively verifiable positive evidence to avoid the need to record a valuation allowance. The Company has recorded a full valuation allowance against its net deferred tax assets as it is more-likely-than-not that the benefit of the deferred tax assets will not be recognized in future periods. A provision of The Patient Protection and Affordable Care Act enacted in 2010, as amended (Affordable Care Act), requires manufacturers of medical devices to pay an excise tax on all U.S. medical device sales. The Company’s expense related to the medical device excise tax, which was recorded in cost of revenue, was $149 and $116 for the three months ended June 30, 2015 and 2014, respectively, and $304 and $230 for the six months ended June 30, 2015 and 2014, respectively. Net Loss Per Share Comprehensive Loss and Accumulated Other Comprehensive Loss Accumulated other comprehensive income (loss) consisted of the following: Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Total accumulated other comprehensive (loss) income at beginning of period $ (798 ) $ (139 ) $ (348 ) $ (139 ) Unrealized Gains on Investments Balance at beginning of period $ (17 ) $ (8 ) $ (54 ) $ (6 ) Other comprehensive income (loss) before reclassifications 2 (11 ) 39 (13 ) Amounts reclassified from accumulated other comprehensive income to other income on the statement of operations — — — — Balance at end of period $ (15 ) $ (19 ) $ (15 ) $ (19 ) Foreign Currency Translation Adjustment Balance at beginning of period $ (781 ) $ (131 ) $ (294 ) $ (133 ) Other comprehensive income (loss) before reclassifications 392 (44 ) 68 (47 ) Amounts reclassified from accumulated other comprehensive income to other income on the statement of operations (139 ) 16 (302 ) 21 Balance at end of period $ (528 ) $ (159 ) $ (528 ) $ (159 ) Total accumulated other comprehensive loss at end of period $ (543 ) $ (178 ) $ (543 ) $ (178 ) Research and Development Advertising Costs — Share-Based Compensation FASB ASC 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company’s Condensed Consolidated Statement of Operations and Comprehensive Loss. The expense has been reduced for estimated forfeitures. FASB ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates the fair value of time-based options on the date of grant using the Black-Scholes option-pricing model (Black-Scholes model). The Company’s determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price, as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. The fair value of market-based performance option grants is estimated at the date of grant using a Monte-Carlo simulation. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company estimates the fair value of restricted stock based upon the grant date closing market price of the Company’s common stock. The Company’s determination of fair value is affected by the Company’s stock price as well as assumptions regarding the number of shares expected to be granted. The Company also has an employee stock purchase plan (ESPP or the Plan) which is available to all eligible employees as defined by the Plan. Under the ESPP, shares of the Company’s common stock may be purchased at a discount. The Company estimates the number of shares to be purchased under the Plan and records compensation expense based upon the fair value of the stock at the beginning of the purchase period using the Black-Scholes model.

Accounting Changes and Error Corrections [Abstract] | |
Recent Accounting Pronouncements | 2. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014 the FASB issued a final standard on revenue from contracts with customers. The standard, issued as FASB ASU 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. In July 2015 the FASB decided to defer the effective date of ASU 2014-09 for entities reporting under U.S. GAAP from interim and annual reporting periods beginning after December 15, 2016 to interim and annual reporting periods beginning after December 15, 2017 and allow early adoption as of the original effective date. A full retrospective or modified retrospective approach may be taken to adopt the guidance in the ASU. The Company is evaluating the impact of the provisions of ASU 2014-09 on its consolidated financial position, results of operations and related disclosures. In June 2015 the FASB issued ASU 2015-10, “Technical Corrections and Improvements” (ASU 2015-10), which amends a wide range of topics in the FASB Accounting Standards Codification. The amendments make minor corrections or minor improvements to the Codification and are effective for fiscal year and interim periods within those fiscal years beginning after December 15, 2015. The Company is reviewing the amendments in ASU 2015-10 and expects that the new guidance will not have a material impact on the Company’s financial reporting. In July 2015 the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory” (ASU 2015-11), which requires entities to measure most inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. ASU 2015-11 is effective prospectively for annual periods beginning after December 15, 2016 and interim periods therein. Early application is permitted. The Company is reviewing the provisions of ASU 2015-11 and expects that the new guidance will not have a material impact on the Company’s financial reporting. |

Fair Value Disclosures [Abstract] | |
Fair Value | 3. FAIR VALUE FASB ASC 820, “Fair Value Measurements and Disclosures” (ASC 820) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: • Level 1—Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. The valuation under this approach does not entail a significant degree of judgment. • Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or 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. The valuation technique for the Company’s Level 2 assets is based on quoted market prices for similar assets from observable pricing sources at the reporting date. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The fair value of the Company’s Level 3 instruments are estimated on the grant date using the Black-Scholes model and they are revalued at the end of each reporting period using the Black-Scholes model. The fair value of the Company’s Level 3 contingent consideration was estimated on the acquisition date of Endoscopic Technologies, Inc. and was revalued at the end of each subsequent reporting period. In accordance with ASC 820, the following table represents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2015: Quoted Prices in Significant Other Significant Other Total Assets: Money market funds $ — $ 23,237 $ — $ 23,237 U.S. government agencies and securities 1,016 — — 1,016 Corporate bonds — 28,685 — 28,685 Total assets $ 1,016 $ 51,922 $ — $ 52,938 There were no changes in the levels or methodology of measurement of financial assets and liabilities during the three or six month periods ended June 30, 2015.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 7. COMMITMENTS AND CONTINGENCIES Lease Commitments The Company leases various types of office, manufacturing and warehouse facilities and equipment under noncancelable operating leases that expire at various terms through 2021. In August 2014 the Company and LM-VP AtriCure, LLC (Landlord), a third party unrelated to the Company, entered into a new building lease (Mason Lease) in order to re-locate its headquarters and West Chester, Ohio facilities from their current location to a building to be constructed on Innovation Way in Mason, Ohio and occupied exclusively by the Company. The term of the Mason Lease is fifteen years with three separate five-year renewal options, at the Company’s option, and begins upon substantial completion of the construction of the building (Commencement Date). We expect to take possession of the building in November 2015. The amount of initial annual base rent of $1,353 is payable monthly beginning on the Commencement Date and is subject to a 2% increase each year during the Lease’s initial term. Upon each renewal, the amount of rent payable will be agreed upon by the Company and Landlord or, if not so agreed upon, by an appraiser. The size of the building subject to the Lease is expected to be approximately 92 square feet. Under the Mason Lease, the Company is responsible for paying real estate taxes, insurance, utilities, operating expenses and most building repairs and maintenance. The Company is also responsible for paying the first $750 of construction-related tenant improvement costs, as well as amounts in excess of the estimated total cost of construction, as defined by the Mason Lease. On the Commencement Date, the Company is required to provide a letter of credit to the Landlord in the amount of $1,250, which amount may decrease or be removed entirely based on the Company’s financial performance. The Company is deemed the owner of the project during the construction period. As a result, approximately $9,176 and $3,941 of project costs incurred to date to construct the building are included in property and equipment and the financing obligation is included in other current liabilities in the Condensed Consolidated Balance Sheets as of June 30, 2015 and December 31, 2014, respectively. An increase in purchases of building under construction and proceeds from the construction financing obligation were also included in the Condensed Consolidated Statement of Cash Flows as of June 30, 2015. Royalty Agreements The Company has certain royalty agreements in place with terms that include payment of royalties based on product revenue from sales of specified current products. The royalty agreements have effective dates as early as 2003 and terms ranging from three years to at least twenty years. The royalties range from 0.75% to 5% of specified product sales. One of the agreements includes minimum quarterly payments of $50 through 2015 and a maximum of $2,000 in total royalties over the term of the agreement. Parties to the royalty agreements have the right at any time to terminate the agreement immediately for cause. Royalty expense of $471 and $262 was recorded as part of cost of revenue for the three months ended June 30, 2015 and 2014, respectively, and $898 and $569 was recorded for the six months ended June 30, 2015 and 2014. Purchase Agreements The Company enters into standard purchase agreements with certain vendors in the ordinary course of business. Outstanding commitments at June 30, 2015 and 2014 were not significant. Legal The Company may, from time to time, become a party to legal proceedings. |

Income Tax Disclosure [Abstract] | |
Income Tax Provision | 8. INCOME TAX PROVISION The Company files federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations. Income taxes are computed using the asset and liability method in accordance with FASB ASC 740, “Income Taxes”, under which deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities. Deferred taxes are measured using provisions of currently enacted tax laws. A valuation allowance against deferred tax assets is recorded when it is more-likely-than-not that such assets will not be fully realized. The Company has recorded a full valuation allowance against its net deferred tax assets as it is more-likely-than-not that the benefit of the deferred tax assets will not be recognized in future periods. Tax credits are accounted for as a reduction of income taxes in the year in which the credit originates. The Company does not expect any significant unrecognized tax benefits to arise over the next twelve months. The Company’s provision for income taxes for continuing operations in interim periods is computed by applying its estimated annual effective rate against its loss before income tax (expense) benefit for the period. In addition, non-recurring or discrete items are recorded during the period in which they occur. The effective tax rate for the three months ended June 30, 2015 and 2014 was (0.17%) and (0.19%), respectively. The effective tax rate for the six months ended June 30, 2015 and 2014 was (0.14%) and (0.31%), respectively. The Company has not had to accrue any interest and penalties related to unrecognized income tax benefits as a result of offsetting net operating losses. However, if the situation occurs, the Company will recognize interest and penalties within the income tax expense (benefit) line in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss and within the related tax liability line in the Condensed Consolidated Balance Sheets. |

Equity Compensation Plans | 9. EQUITY COMPENSATION PLANS The Company has several share-based incentive plans: the 2001 Stock Option Plan (2001 Plan), the 2005 Equity Incentive Plan (2005 Plan), the Amended and Restated 2014 Stock Incentive Plan (2014 Plan) and the 2008 Employee Stock Purchase Plan (ESPP). 2001 Plan, 2005 Plan and 2014 Plan Neither the 2001 Plan nor 2005 Plan is currently used for granting incentives. The Company granted awards under the 2005 Plan until the 2014 Annual Meeting of Stockholders at which stockholders adopted the 2014 Plan. Pursuant to its terms, the 2014 Plan supersedes and replaces the 2005 Plan. Under the 2014 Plan, the Board of Directors may grant incentive stock options to employees and any parent or subsidiary’s employees, and may grant nonstatutory stock options, restricted stock or stock appreciation rights to employees, directors and consultants of the Company and any parent or subsidiary’s employees, directors and consultants. The administrator (currently the Compensation Committee of the Board of Directors) has the power to determine the terms of any awards, including the number of shares subject to each award, the exercisability of the awards and the form of consideration. As of June 30, 2015, 8,949 shares of common stock had been reserved for issuance under the 2014 Plan. Options granted under the plans generally expire ten years from the date of grant. Options granted from the 2005 Plan and 2014 Plan generally vest at a rate of 25% on the first anniversary date of the grant and ratably each month thereafter over the following three years. Restricted stock awards granted under the 2005 Plan and 2014 Plan generally vest 25% annually over four years from date of grant. Employee Stock Purchase Plan (ESPP) During 2008 the Company established the Employee Stock Purchase Plan which is available to eligible employees as defined in the ESPP. Under the ESPP, shares of the Company’s common stock may be purchased at a discount (currently 15%) of the lesser of the closing price of the Company’s common stock on the first trading day or the last trading day of the offering period. The offering period (currently six months) and the offering price are subject to change. Participants may not purchase more than $25 of the Company’s common stock in a calendar year and, effective January 1, 2014, may not purchase more than 3 shares during an offering period. Beginning on January 1, 2009 and on the first day of each fiscal year thereafter during the term of the ESPP, the number of shares available for sale under the ESPP shall be increased by the lesser of (i) two percent (2%) of the Company’s outstanding shares of common stock as of the close of business on the last business day of the prior calendar year, not to exceed 600 shares, or (ii) a lesser amount determined by the Board of Directors. At June 30, 2015 there were 524 shares available for future issuance under the ESPP. Valuation and Expense Information Under FASB ASC 718 The following table summarizes share-based compensation expense related to employee share-based compensation under FASB ASC 718 for the three and six months ended June 30, 2015 and 2014.

Revenue Recognition | Revenue Recognition Pursuant to the Company’s standard terms of sale, revenue is recognized when title to the goods and risk of loss transfers to customers and there are no remaining obligations that will affect the customers’ final acceptance of the sale. Generally, the Company’s standard terms of sale define the transfer of title and risk of loss to occur upon shipment to the respective customer. The Company generally does not maintain any post-shipping obligations to the recipients of the products. No installation, calibration or testing of this equipment is performed by the Company subsequent to shipment to the customer in order to render it operational. Revenue includes shipping and handling revenue of $271 and $236 for the three months ended June 30, 2015 and 2014, respectively, and $518 and $463 for the six months ended June 30, 2015 and 2014, respectively. Cost of freight for shipments made to customers is included in cost of revenue. Sales and other value-added taxes collected from customers and remitted to governmental authorities are excluded from revenue. The Company sells its products primarily through a direct sales force, with certain international markets sold through distributors. Terms of sale are generally consistent for both end-users and distributors except that payment terms are generally net 30 days for end-users and net 60 days for distributors. |

Property and Equipment | Property and Equipment Generators and other capital equipment (such as the Company’s switchbox units and cryosurgical consoles) are loaned at no cost to direct customers that use the Company’s disposable products. Depreciation of such assets is included in cost of revenue. The estimated useful lives of this equipment are based on anticipated usage by customers and the timing and impact of expected new technology rollouts by the Company. To the extent the Company experiences changes in the usage of this equipment or introduces new technologies, the estimated useful lives of this equipment may change in a future period. Depreciation related to these generators was $673 and $498 for the three months ended June 30, 2015 and 2014, respectively, and $1,293 and $959 for the six months ended June 30, 2015 and 2014, respectively. As of June 30, 2015 and December 31, 2014, the net carrying amount of loaned equipment included in net property and equipment in the Condensed Consolidated Balance Sheets was $4,799 and $4,141, respectively. The Company reviews property and equipment for impairment using its best estimates based on reasonable and supportable assumptions and projections. |

Other Income | Other Income The Company recorded net foreign currency transaction (losses) gains of ($46) and $16 for the three months ended June 30, 2015 and 2014, respectively, and ($209) and $21 for the six months ended June 30, 2015 and 2014, respectively, primarily in connection with settlements of its intercompany balance with AtriCure Europe. The Company periodically is awarded grants to support research and development activities or education activities. The Company recognizes grant income when the funds are earned. The Company recorded grant income of $0 and $137 during the three months ended June 30, 2015 and 2014, respectively. Grant income of $35 and $500 was recorded for the six month periods ended June 30, 2015 and 2014, respectively. The Company historically issued stock options to non-employee consultants as a form of compensation for services provided to the Company. Because the non-employee options require settlement by the Company’s delivery of registered shares and because the tax withholding provisions in the awards allow the options to be partially net-cash settled, these options, when vested, are no longer eligible for equity classification and are, thus, subsequently accounted for as derivative liabilities under FASB ASC 815, “Derivatives and Hedging” (ASC 815) until the awards are ultimately either exercised or forfeited. Accordingly, the vested non-employee options are classified as liabilities and remeasured at fair value through earnings at each reporting period. During the three months ended June 30, 2015 and 2014, $44 and ($19), respectively, of expense (income) was recorded as a result of the remeasurement of the fair value of these fully vested stock options. During the six months ended June 30, 2015 and 2014, $57 and ($117), respectively, of expense (income) was recorded as a result of the remeasurement of the fair value of these fully vested stock options. |
Taxes | Taxes The Company’s estimate of the valuation allowance for deferred tax assets requires it to make significant estimates and judgments about its future operating results. Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred tax assets on a quarterly basis to determine if valuation allowances are required by considering all available evidence. Deferred tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable income, exclusive of reversing temporary differences and carryforwards, taxable income in carry-back years and tax planning strategies that are both prudent and feasible. In evaluating whether to record a valuation allowance, the applicable accounting standards deem that the existence of cumulative losses in recent years is a significant piece of objectively verifiable negative evidence that must be overcome by objectively verifiable positive evidence to avoid the need to record a valuation allowance. The Company has recorded a full valuation allowance against its net deferred tax assets as it is more-likely-than-not that the benefit of the deferred tax assets will not be recognized in future periods. A provision of The Patient Protection and Affordable Care Act enacted in 2010, as amended (Affordable Care Act), requires manufacturers of medical devices to pay an excise tax on all U.S. medical device sales. The Company’s expense related to the medical device excise tax, which was recorded in cost of revenue, was $149 and $116 for the three months ended June 30, 2015 and 2014, respectively, and $304 and $230 for the six months ended June 30, 2015 and 2014, respectively. |

Share-Based Compensation | Share-Based Compensation FASB ASC 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company’s Condensed Consolidated Statement of Operations and Comprehensive Loss. The expense has been reduced for estimated forfeitures. FASB ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates the fair value of time-based options on the date of grant using the Black-Scholes option-pricing model (Black-Scholes model). The Company’s determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price, as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. The fair value of market-based performance option grants is estimated at the date of grant using a Monte-Carlo simulation. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company estimates the fair value of restricted stock based upon the grant date closing market price of the Company’s common stock. The Company’s determination of fair value is affected by the Company’s stock price as well as assumptions regarding the number of shares expected to be granted. The Company also has an employee stock purchase plan (ESPP or the Plan) which is available to all eligible employees as defined by the Plan. Under the ESPP, shares of the Company’s common stock may be purchased at a discount. The Company estimates the number of shares to be purchased under the Plan and records compensation expense based upon the fair value of the stock at the beginning of the purchase period using the Black-Scholes model. |
