	BASIS OF PRESENTATION
	Nature of the Business
	The accompanying condensed consolidated financial statements include the accounts of Lionbridge Technologies, Inc. and its wholly owned subsidiaries (collectively, “Lionbridge” or the “Company”). These financial statements are unaudited. However, in the opinion of management, the condensed consolidated financial statements include all adjustments, all of a normal recurring nature, necessary for the fair statement of results for the periods presented. Interim results are not necessarily indicative of results expected for a full year. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a complete presentation of the operations, financial position and cash flows of the Company in conformity with U.S. generally accepted accounting principles (“GAAP”). The condensed consolidated balance sheet data as of December 31, 2013 was derived from audited financial statements, but does not include all disclosures required by GAAP for annual financial statements. These statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	The Company’s preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Estimates are used (but not limited to) when accounting for collectability of receivables, calculating service revenue using a proportional performance assessment and valuing intangible assets and deferred tax assets. Actual results could differ from these estimates.

	STOCKHOLDERS’ EQUITY AND STOCK-BASED COMPENSATION
	Restricted Stock Awards
	Lionbridge issued 1,336,500 and 188,542 shares of restricted common stock and restricted stock units, respectively, under the Company’s 2011 Stock Incentive Plan, during the nine months ended September 30, 2014 representing a fair market value of $8.4 million. Of the total 1,525,042 shares of restricted common stock and restricted stock units issued in the nine months ended September 30, 2014, 1,161,450 have restrictions on disposition which lapse over four years from the date of grant, 35,592 have restrictions on disposition which lapse over thirteen months from the grant date and 328,000 shares of restricted common stock were granted to certain employees through the long-term incentive plan (the “LTIP”) as long-term performance-based stock incentive awards under the Corporation’s 2011 Stock Incentive Plan. Pursuant to the terms of the LTIP, restrictions with respect to the stock will generally lapse upon the achievement of revenue and profitability targets within the two calendar years from and including the year of grant. The grant date fair value of the shares is recognized over the requisite period of performance once achievement of criteria is deemed probable. On a quarterly basis, the Company estimates the likelihood of achieving performance goals and records expense accordingly. Actual results, and future changes in estimates, may differ substantially from the Company’s current estimates. If the targets are not achieved, the shares will be forfeited by the employee in accordance with the forfeiture table per the grant agreements.
	Stock-based Compensation
	The Company recognizes expense for stock options, performance-based restricted stock awards and time-based restricted stock awards pursuant to the authoritative guidance. Total compensation expense related to stock options, performance-based restricted stock awards and time-based restricted stock awards are classified in the condensed consolidated statements of operations line items as follows:
		Three Months Ended					Nine Months Ended
		September 30,					September 30,
	(In thousands)	2014			2013		2014		2013

	Research and development	19			13		66		37
	Total stock-based compensation expense	$	2,008		$	1,651	$	5,814	$	4,961
	As of September 30, 2014, future compensation cost related to non-vested stock options, less estimated forfeitures, is approximately $1.1 million and will be recognized over an estimated weighted-average period of approximately 2.4 years. Lionbridge currently expects to amortize $10.3 million of unamortized compensation in connection with restricted stock awards outstanding as of September 30, 2014 over an estimated weighted-average period of approximately 2.4 years.
	Share Repurchasing Program
	On October 30, 2012, Lionbridge’s Board of Directors authorized a share repurchasing program for up to $18 million over three years. During the program, the Company is authorized to repurchase Lionbridge common shares with a total value up to $6 million per year, subject to certain market rate conditions. The Company made the following purchases since the program’s inception:

	UNBILLED RECEIVABLES AND DEFERRED REVENUE
	Unbilled receivables represent revenue recognized not yet billed. Unbilled receivables are calculated for each individual project based on the proportional delivery of services at the balance sheet date. Billing of amounts in unbilled receivables occurs according to customer-agreed payment schedules or upon completion of specified project milestones. All of Lionbridge’s projects in unbilled receivables are expected to be billed and collected within 1 year.
	Deferred revenue represents advance billings to customers. Deferred revenue is calculated for each individual project and constitutes a performance obligation for which revenue will be recognized as services are delivered.

Debt	'
	DEBT
	On October 30, 2013, the Company amended and restated the Credit Agreement with HSBC Bank, as Administrative Agent and a lender, and a syndicate of other lenders (the “Amended and Restated Credit Agreement”). The Amended and Restated Credit Agreement includes a $65 million senior secured revolving credit facility, which includes a $10 million sublimit for the issuance of standby letters of credit and a $10 million sublimit for swing-line loans. The Company may request, at any time and from time to time, that the revolving credit facility be increased by an amount not to exceed $35 million, dependent upon certain conditions. The interest rates are in the range of Prime Rate plus 0.25%—1.00% or LIBOR plus 1.25%—2.00% (at the Company’s discretion), depending on certain conditions. This facility expires on October 30, 2018, after which time the Company may need to secure new financing. The Company cannot assure that it will be able to secure new financing, or financing on terms that are acceptable. At September 30, 2014, $27.0 million was outstanding with an interest rate of 1.41%. The fair value of debt approximates its current value of $27.0 million as of September 30, 2014. The fair value of debt approximates its current value at September 30, 2014, and would be classified as a Level 2 measurement due to the use of inputs based on similar liabilities in the market.
	The Company is required to maintain leverage and fixed charge coverage ratios and to comply with other covenants in its revolving credit agreement. The leverage ratio is calculated by dividing the Company’s total outstanding indebtedness at each quarter end by its adjusted earnings before interest, taxes, depreciation and certain other non-cash expenses during the four consecutive quarterly periods then ended. The fixed charge coverage ratio is calculated by dividing the Company’s adjusted earnings before interest, taxes, depreciation and certain other non-cash expenses minus capital expenditures for each consecutive four quarterly periods by its interest paid and cash paid on taxes during each such consecutive four quarterly periods. The Company was in compliance with both of these ratios as well as all other financial covenants as of September 30, 2014.
	On November 8, 2014 the Company signed a commitment letter to amend and restate the Credit Agreement discussed above. See note 15—Subsequent Events for further details.

Earnings Per Share [Abstract]	'
Net Income Per Share	'
	NET INCOME PER SHARE
	Basic earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding. For the purposes of calculating diluted earnings per share, the denominator includes both the weighted-average number of shares of common stock outstanding and the number of dilutive common stock equivalents such as stock options and unvested restricted stock, as determined using the treasury stock method. Shares used in calculating basic and diluted earnings per share for the three and nine months ended September 30, 2014 and 2013, respectively, are as follows:
		Three Months Ended		Nine Months Ended
		September 30,		September 30,
	(In thousands)	2014	2013	2014	2013
	Weighted-average number of shares of common stock outstanding-basic	60,012	59,523	60,263	60,461

	Weighted-average number of shares of common stock outstanding-diluted	62,646	61,451	63,070	62,006
	Options and unvested restricted stock to purchase 0.9 million and 2.6 million shares of common stock for the three months ended September 30, 2014 and 2013, respectively, were not included in the calculation of diluted net income per share as their effect would be anti-dilutive. Options and unvested restricted stock to purchase 0.4 million and 3.8 million shares of common stock for the nine months ended September 30, 2014 and 2013, respectively, were not included in the calculation of diluted net income per share as their effect would be anti-dilutive.

	RESTRUCTURING AND OTHER CHARGES
	During the nine months ended September 30, 2014, Lionbridge recorded $1.8 million of restructuring and other charges, which included restructuring charges of $1.1 million for workforce reductions in Europe, Asia and North America consisting of 23 technical staff, 1 administrative staff and 1 sales staff, $0.2 million of charges representing additional costs recorded for a previously vacated facility in order to reflect changes in initial estimates of a sublease arrangement due to current economic conditions, acquisition-related costs of $0.6 million and $0.1 million of accretion related to the contingent consideration from the Virtual Solutions, Inc. (“VSI”) acquisition in 2012. These charges were offset by reductions in expense related to changes in the estimated fair value of contingent consideration of $0.1 million from the E5 Global Holdings, Inc. (“E5”) acquisition in 2013 and deferred consideration of $0.1 million from the acquisition of Productive Resources, LLC (“PRI”) in 2012. All facility charges, $0.9 million of workforce charges, acquisition-related costs and the change in fair value of PRI deferred consideration relate to the Company's Global Language and Content (“GLC”) segment. Workforce reductions of $0.3 million, the VSI contingent consideration accretion and the change in fair value of the E5 contingent consideration relate to the Company’s Global Enterprise Solutions (“GES”) segment. The Company made $1.7 million of cash payments in the nine months ended September 30, 2014, which related to the GLC and GES segments.
	During the nine months ended September 30, 2013, Lionbridge recorded $3.4 million of restructuring and other charges, which included restructuring charges of $2.0 million for workforce reductions in Europe, the Americas and Asia consisting of 18 technical staff, 15 administrative staff and 8 sales staff, and $0.2 million of additional costs recorded for a previously vacated facility in order to reflect changes in initial estimates of a sublease arrangement due to current economic conditions. These charges related primarily to the Company’s GLC segment. The Company made $3.0 million of cash payments in the nine months ended September 30, 2013 all of which related to the GLC operating segments. The remaining $1.2 million of other charges recorded in the three months ended September 30, 2013 related to the Company’s engagement in strategic initiatives, a true-up of the deferred acquisition liability fair value from the VSI acquisition and acquisition costs related to the Company’s acquisition of E5 on October 2, 2013.
	The following table summarizes the restructuring accrual activity for the nine months ended September 30, 2014 and 2013, respectively, by category:

	At September 30, 2014, the Company’s condensed consolidated balance sheet includes accruals totaling $2.4 million related to employee termination costs and vacated facilities. Lionbridge currently anticipates that approximately $1.0 million of these will be fully paid within twelve months. The remaining $1.4 million relates to lease obligations on unused facilities expiring through 2026 and is included in other long-term liabilities in the Company’s condensed consolidated balance sheet.

	INCOME TAXES
	The provision for income taxes for the three months ended September 30, 2014 and 2013 was $1.1 million and $1.3 million, respectively. The provision for income taxes for the nine months ended September 30, 2014 and 2013 was $2.6 million. The provision for income taxes for the three and nine months ended September 30, 2014 and 2013 consisted primarily of taxes on income in foreign jurisdictions, interest, and penalties recorded in relation to the Company’s uncertain tax positions.
	The balance of unrecognized tax benefits at September 30, 2014, not including interest and penalties, was $3.7 million, which, if recognized, would affect the effective income tax rate in future periods. Lionbridge also recognizes interest and penalties related to unrecognized tax benefits in tax expense. At September 30, 2014, Lionbridge had approximately $1.5 million of interest and penalties accrued related to unrecognized tax benefits.
	The Company conducts business globally and in the normal course of business is subject to examination by local, state and federal jurisdictions in the United States as well as in multiple foreign jurisdictions. Currently, no Internal Revenue Service audits are underway and audits in Belgium, Canada, China, Finland, France, Poland and India are in varying stages of completion. Open audit years are dependent upon the tax jurisdiction and range from 2003 to present.
	At September 30, 2014, no provision for U.S. income and foreign withholding taxes has been made for unrepatriated foreign earnings because it is expected that such earnings will be reinvested indefinitely.
	Lionbridge’s management has evaluated the positive and negative evidence as it relates to the realizability of its deferred tax assets. Under the applicable accounting standards, management has considered Lionbridge’s history of losses and concluded that, with the exception of certain foreign tax jurisdictions, it is more-likely-than-not that Lionbridge will not generate sufficient future taxable income to benefit from the tax assets prior to their expiration. Accordingly, full valuation allowances have been maintained against those tax assets. As a result, no income tax benefit has been recorded for the losses incurred in the U.S. and certain foreign jurisdictions during the nine months ended September 30, 2014.

	SEGMENT INFORMATION
	Lionbridge has determined that its operating segments are those that are based on its method of internal reporting, which separately presents its business based on the service performed. The Company is reporting its results among the following three business segments:
	GLC—this segment includes solutions that enable the translation, localization and worldwide multilingual release of clients’ online content, sales and marketing information, products and related technical support and training materials to meet the language, cultural, technical and industry-specific requirements of customers in local markets throughout the world. As part of its GLC solutions, Lionbridge also provides global marketing services, and provides engineering, technical documentation and drafting services for clients who market to and support customers in global markets. Lionbridge GLC solutions utilize the Company’s cloud-based technology platforms and applications, its global crowd of qualified professional linguists, translators and in-country specialists and its global service delivery model, which make the translation, localization and content management processes more efficient for Lionbridge and its clients.
	GES—formerly referred to as GDT, this segment includes Lionbridge’s services related to testing clients’ software, websites, mobile applications and hardware utilizing a cost-efficient, blended on-site and offshore model. The GES segment also includes Lionbridge’s specialized business process crowdsourcing services including search relevance testing, in-country testing for mobile devices, and data management solutions. Lionbridge’s business process crowdsourcing solutions combine a dedicated crowd of pre-qualified, in-country professionals, Lionbridge’s secure, task management platform and Lionbridge’s proven program management expertise. This combination enables Lionbridge to align the appropriate combination of skill, capability and geography to meet each client’s requirements.
	Interpretation—this segment includes interpretation services for government and business organizations that require experienced linguists. Lionbridge provides interpretation communication services in more than 360 languages and dialects, including on-site interpretation, over-the-phone interpretation and interpreter testing, training, and assessment services.
	The Company’s internal reporting does not include the allocation of certain expenses to the operating segments but instead includes those other expenses in unallocated corporate and other expense. Unallocated expenses primarily include corporate expenses, such as interest expense, restructuring, impairment and other charges, foreign exchange gains and losses and governance expenses, as well as finance, information technology, human resources, legal, treasury and marketing expenses. The Company determines whether a cost is charged to a particular business segment or is retained as an unallocated cost based on whether the cost relates to a corporate function or to a direct expense associated with the particular business segment. For example, corporate finance, corporate information technology and corporate human resource expenses are unallocated, whereas operating segment finance, information technology and human resource expenses are charged to the applicable operating segment.
	The table below presents information about the Company’s segment data for the three and nine months ended September 30, 2014 and 2013. Asset information by reportable segment is not reported, since the Company does not produce such information internally.

Goodwill, Acquistion-Related Intangible Assets, and Other Long Lived Assets	'
	GOODWILL, ACQUISITION-RELATED INTANGIBLE ASSETS, AND OTHER LONG LIVED ASSETS
	Lionbridge assesses the impairment of goodwill and acquisition-related intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Such events or conditions could include an economic downturn in the industries to which Lionbridge provides services; increased competition; an increase in operating or other costs; additional volatility in international currencies; the pace of technological improvements; or other information regarding Lionbridge’s market value, such as a reduction in stock price to a price near or below the book value of the Company for an extended period of time. When Lionbridge determines that the carrying value of goodwill may not be recoverable based upon one or more of these indicators of impairment, the Company initially assesses any impairment using fair value measurements based on projected discounted cash flow valuation models and the market approach. In addition, goodwill is reviewed for impairment on an annual basis. At December 31, 2013, the Company performed its annual test of goodwill to determine if an impairment existed. This test determined that each reporting unit’s fair value substantially exceeded the carrying value of the net assets of each respective reporting unit, using projected discounted cash flow modeling and the market approach. As a result, no impairment was recorded for the year ended December 31, 2013. There were no events or changes in circumstances during the nine months ended September 30, 2014 which indicated that an assessment of the impairment of goodwill and acquisition-related intangible assets was required.
	The Company evaluates whether there has been impairment in the carrying value of its long-lived assets if circumstances indicate that a possible impairment may exist. Impairment in the carrying value of an asset is assessed when the undiscounted expected future operating cash flows derived from the asset grouping are less than its carrying value. If it is determined that the asset group is impaired then it is written down to its estimated fair value. Factors that could lead to an impairment of its long-lived assets include a worsening in customer attrition rates compared to historical attrition rates, lower than initially anticipated cash flows associated with customer relationships, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for our overall business, identification of other impaired assets within a reporting unit, disposition of a significant portion of an operating segment, significant negative industry or economic trends, significant decline in our stock price for a sustained period and a decline in our market capitalization relative to net book value.
	Intangible assets arose from acquisitions made prior to 2011 and the acquisitions of PRI in June 2012, VSI in November 2012, E5 in October 2013 and Darwin Zone, S.A. (“Darwin”) in May 2014. Intangibles arising from acquisitions made prior to 2011 are being amortized using an economic consumption method over an estimated useful life of; (i) 3 to 12 year for customer relationships, (ii) 3 to 5 years for customer contracts and (iii) 1 to 4 years for acquired technology. Intangibles arising from the acquisitions of PRI, VSI, E5 and Darwin are being amortized over a straight-line basis over the estimated useful life of; (i) 5 to 10 years for acquired technology, (ii) 2 to 12 years for customer relationships, (iii) 1 to 5 years for non-compete agreements and (iv) 1 to 2 years for trademarks.

Acquisitions	'
	ACQUISITIONS
	Darwin Zone, S.A.
	On May 16, 2014, the Company acquired 100% of the shares of Darwin for $2.4 million in cash, (including the effect of working capital adjustments). Darwin, a provider of digital marketing solutions, is included in the Company’s GLC operating segment. The acquisition expands the Company’s delivery model for cost efficient digital marketing solutions in the Central America region.
	The total acquisition date fair value of the consideration transferred was estimated at $2.4 million. The assets and liabilities associated with Darwin were recorded at their fair values as of the acquisition date and the amounts as follows:
	(In thousands)
	Cash	$	36
	Accounts receivable and unbilled receivables	698
	Other current assets	115
	Property and equipment	206
	Intangible assets	824
	Goodwill	984
	Total assets	2,863
	Accounts payable	(222		)
	Other liabilities	(249		)
	Total consideration transferred	$	2,392
	Intangible assets acquired totaling $0.8 million include customer relationships of $0.7 million, a non-compete agreement executed by a key employee (“the Non-Competition Agreement”) of $0.1 million and a trade name of $44 thousand.
	The estimated fair value attributed to the customer relationships was determined based upon a discounted cash flow forecast. Cash flows were discounted at a rate of 16%. The fair value of the customer relationships will be amortized over a period of 5 years on a straight-line basis, which approximates the pattern in which the economic benefits of the acquired customer list are expected to be realized. The fair value of the Non-Competition Agreement will be amortized over 5 years on a straight-line basis, which approximates the pattern in which the economic benefits of the non-compete agreement is expected to be realized.
	Goodwill represents the excess of the purchase price over the fair values of the net tangible and intangible assets acquired and is primarily the result of expected synergies. None of the goodwill or identifiable intangibles associated with this transaction will be deductible for tax purposes.
	Transaction costs related to this acquisition were approximately $0.1 million during the nine months ended September 30, 2014 and are included in restructuring and other charges in the Company’s condensed consolidated statement of operations.
	Since the date of the acquisition, May 16, 2014, the Company has recorded $1.5 million of revenue attributable to Darwin within its consolidated financial statements. Since the date of the acquisition, earnings attributable to Darwin do not have a material impact within the Company's consolidated financial statements. The proforma results of operations including Darwin as if it were acquired at the beginning of all periods presented were not material to the consolidated operating results of the Company in either period presented.
	E5 Global Holdings, Inc.
	On October 2, 2013, the Company acquired 100% of the shares of E5, a U.S.-based privately-held provider of application development and testing solutions with a track record of providing secure, high-quality testing services using a China-based delivery model. The acquisition enables the Company to expand its presence in China, meet growing demand for integrated onshore and offshore solutions and access E5’s long-standing relationships with clients in the hospitality and financial services industries. The results of operations of E5 are included in the Company’s results of operations from the date of acquisition. E5 is included in the Company’s GES operating segment.
	The Company made an initial cash payment of approximately $1.4 million at closing with an additional $0.2 million of deferred purchase consideration due on the first anniversary of the closing date. Under the terms of the purchase agreement, the former owners of E5 would also be eligible to receive additional cash consideration up to $2.2 million, contingent on the fulfillment of certain revenue-based financial conditions during the two years ended September 30, 2015. Using a discounted cash flow method, the Company recorded an estimated liability related to the earn-out of $0.3 million as of the acquisition date and as of March 31, 2014. On June 30, 2014, the Company and the former owners agreed to the early release of the $0.2 million of deferred consideration. The parties also agreed to satisfaction in full of the Company’s obligations with respect to any contingent payments that may become due in the future in exchange for payment, on June 30, 2014, of $0.2 million to the former owners. As a result of the early payment of the contingent payment for $0.2 million, the Company recorded $0.1 million reduction in expense in restructuring, impairment and other charges in the Company’s condensed consolidated statement of operations.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	FAIR VALUE MEASUREMENTS
	ASC 820 – Fair Value Measurements and Disclosures (“ASC 820”) provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. ASC 820 defines fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required by the standard that Lionbridge uses to measure fair value, as well as the assets and liabilities that the Company values using those levels of inputs.
	Level 1:	Quoted prices in active markets for identical assets or liabilities. Lionbridge did not have any financial assets and liabilities as of September 30, 2014 designated as Level 1.
	Level 2:	Observable inputs other than Level 1 prices 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 related assets or liabilities. As a result of the PRI acquisition in 2012 Lionbridge acquired a $2.0 million promissory note, using an interest rate similar to quoted market rates for a similar liability, to be paid in three installments and matures in June 2015.
	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. Lionbridge has contingent and deferred consideration assumed as a result of the VSI acquisition of $1.6 million as of September 30, 2014 and has contingent and deferred consideration assumed as a result of the VSI and E5 acquisitions of $3.1 million as of December 31, 2013 designated as Level 3. The Company’s contingent purchase consideration is valued by probability weighting expected payment scenarios and then applying a discount based on the present value of the future cash flow streams. This liability is classified as Level 3 because the probability weighting of future payment scenarios is based on assumptions developed by management. The Company determined a probability weighting that is weighted towards VSI achieving the revenue target at the time of acquisition and the discount rate that is based on the company’s weighted average cost of capital which is then adjusted for the time value of money. The probability weighting has been adjusted during the nine months ended September 30, 2014 as the actual results provide the Company with more reliable information to weight the probability scenarios. This adjustment resulted in a $0.1 million increase to the contingent consideration during the nine months ended September 30, 2014. The discount rate and factor have remained consistent during the nine months ended September 30, 2014. The Company believes that any probable changes during future periods to these assumptions will not have a material effect on the contingent considerations. On June 30, 2014 the former owners of E5 agreed to the satisfaction in full of the Company’s contingent payment obligations. This resulted in a $0.1 million decrease to the contingent consideration during the nine months ended September 30, 2014.

	RECENT ACCOUNTING PRONOUNCEMENTS
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2014-09 Revenue from Contracts with Customers (Topic 606) which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. For the Company, the standard will be effective in the first quarter of 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company has not yet selected a transition method. The Company is currently evaluating the potential changes from this ASU to its future financial reporting and disclosures.
	In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under the new guidance, management will be required to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, and for annual and interim periods thereafter. This ASU is not expected to have an impact on the Company's financial statements or disclosures.
	Other new pronouncements issued but not effective until after September 30, 2014 are not expected to have a material impact on our financial position, results of operations or liquidity.

	In connection with the lease of the Company's headquarters in Waltham, Massachusetts executed in March 2014, the Company's landlord funded $1.4 million in leasehold improvements during the three months ended September 30, 2014. The capitalized leasehold improvements are being amortized over eleven years, the remaining life of the lease, and are reflected in property and equipment, net on the Condensed Consolidated Balance Sheets. The leasehold improvements funded by the landlord are treated as lease incentives. Accordingly, the $1.4 million funded by the landlord was recorded as a deferred rent liability and is reflected on other long-term liabilities on the Condensed Consolidated Balance Sheets. The deferred rent liability is being amortized over eleven years, the remaining life of the lease. As of September 30, 2014 $1.3 million is reflected on other long-term liabilities.

Under the terms of the purchase agreement, the former owners of Clay Tablet will be eligible to receive additional cash consideration of up to $2.5 million, contingent on the fulfillment of certain revenue based financial conditions and continued employment during the three years ending September 30, 2017. The contingent consideration period can be extended an additional year. The transaction will be accounted for as a business combination using the acquisition method. Due to the timing of this acquisition, certain disclosures, including the preliminary allocation of the purchase price, have been omitted from this Quarterly Report on Form 10-Q because the initial accounting for the business combination was incomplete as of the filing date. The Company expects the preliminary allocation of the purchase price and other disclosures to be included in the Company's Annual Report on Form 10-K for 2014.
	On November 9, 2014, the Company entered into a definitive agreement to acquire CLS Holding AG, a global language service provider headquartered in Switzerland. The transaction will be effected through the purchase of (a) 100% of the outstanding shares of Tuscany Holding AG, a holding company that holds 68.9% of the outstanding shares of CLS Holding and (b) 31.1% of the shares of CLS Corporate Language Services Holding AG held by certain management sellers. The acquisition is expected to be completed in early 2015, pending certain closing conditions. Consideration will be a cash payment and is expected to be approximately Fr.74 million Swiss Francs, or approximately $77 million US Dollars (at November 7, 2014 exchange rate), subject to estimated cash and debt adjustments at closing and certain post-closing adjustments. Due to the timing of this acquisition, certain disclosures, including the preliminary allocation of the purchase price, have been omitted from this Quarterly Report on Form 10-Q because the initial accounting for the business combination was incomplete as of the filing date. The Company expects the preliminary allocation of the purchase price and other disclosures to be included in the Company's Quarterly Report on Form 10-Q for the first quarter of 2015.
	On November 8, 2014, in order to fund the CLS Holding AG acquisition the Company signed a commitment letter to amend and restate the Credit Agreement with HSBC Bank, as Administrative Agent and a lender, and a syndicate of other lenders. The terms of the commitment letter include (a) a $100 million senior secured revolving credit facility, which includes a $10 million sublimit for the issuance of standby letters of credit and a $10 million sublimit for swing-line loans and (b) a senior secured term loan facility in an aggregate amount of $35 million. The Company may request, at any time and from time to time, that the revolving credit facility be increased by an amount not to exceed $65 million, dependent upon certain conditions. The interest rates are in the range of Prime Rate plus 0.25%—1.00% or LIBOR plus 1.25%—2.00% (at the Company’s discretion), depending on certain conditions. Both facilities expire after five years from the date of entering into the proposed amendment, after which time the Company may need to secure new financing. The Company cannot assure that it will be able to secure new financing, or financing on terms that are acceptable.
	The Company is required to maintain leverage and fixed charge coverage ratios and to comply with other covenants in the Amended and Restated Credit Agreement. The leverage ratio is calculated by dividing the Company’s total outstanding indebtedness at each quarter end by its adjusted earnings before interest, taxes, depreciation and certain other non-cash expenses during the four consecutive quarterly periods then ended. The fixed charge coverage ratio is calculated by dividing the Company’s adjusted earnings before interest, taxes, depreciation and certain other non-cash expenses minus capital expenditures for each consecutive four quarterly periods by its interest paid and cash paid on taxes during each such consecutive four quarterly periods.

	The accompanying condensed consolidated financial statements include the accounts of Lionbridge Technologies, Inc. and its wholly owned subsidiaries (collectively, “Lionbridge” or the “Company”). These financial statements are unaudited. However, in the opinion of management, the condensed consolidated financial statements include all adjustments, all of a normal recurring nature, necessary for the fair statement of results for the periods presented. Interim results are not necessarily indicative of results expected for a full year. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and footnotes necessary for a complete presentation of the operations, financial position and cash flows of the Company in conformity with U.S. generally accepted accounting principles (“GAAP”). The condensed consolidated balance sheet data as of December 31, 2013 was derived from audited financial statements, but does not include all disclosures required by GAAP for annual financial statements. These statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	The Company’s preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Estimates are used (but not limited to) when accounting for collectability of receivables, calculating service revenue using a proportional performance assessment and valuing intangible assets and deferred tax assets. Actual results could differ from these estimates.

Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Lionbridge assesses the impairment of goodwill and acquisition-related intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Such events or conditions could include an economic downturn in the industries to which Lionbridge provides services; increased competition; an increase in operating or other costs; additional volatility in international currencies; the pace of technological improvements; or other information regarding Lionbridge’s market value, such as a reduction in stock price to a price near or below the book value of the Company for an extended period of time. When Lionbridge determines that the carrying value of goodwill may not be recoverable based upon one or more of these indicators of impairment, the Company initially assesses any impairment using fair value measurements based on projected discounted cash flow valuation models and the market approach. In addition, goodwill is reviewed for impairment on an annual basis. At December 31, 2013, the Company performed its annual test of goodwill to determine if an impairment existed. This test determined that each reporting unit’s fair value substantially exceeded the carrying value of the net assets of each respective reporting unit, using projected discounted cash flow modeling and the market approach. As a result, no impairment was recorded for the year ended December 31, 2013. There were no events or changes in circumstances during the nine months ended September 30, 2014 which indicated that an assessment of the impairment of goodwill and acquisition-related intangible assets was required.
	The Company evaluates whether there has been impairment in the carrying value of its long-lived assets if circumstances indicate that a possible impairment may exist. Impairment in the carrying value of an asset is assessed when the undiscounted expected future operating cash flows derived from the asset grouping are less than its carrying value. If it is determined that the asset group is impaired then it is written down to its estimated fair value. Factors that could lead to an impairment of its long-lived assets include a worsening in customer attrition rates compared to historical attrition rates, lower than initially anticipated cash flows associated with customer relationships, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for our overall business, identification of other impaired assets within a reporting unit, disposition of a significant portion of an operating segment, significant negative industry or economic trends, significant decline in our stock price for a sustained period and a decline in our market capitalization relative to net book value.
