	2. Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Such interim financial information is unaudited but reflects all adjustments that, in the opinion of management, are necessary for the fair presentation of the interim periods presented. All such adjustments are, in the opinion of management, of a normal recurring nature. The results of operations presented in this Quarterly Report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any future periods. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited financial statements and footnotes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2012. All information is presented in thousands, except per share amounts and where specifically noted.
	The consolidated financial statements include accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The Company has revised the statement of cash flow presentation for certain remeasurement gains and losses from the “Effect of exchange rate changes on cash and cash equivalents” line item to the “Foreign currency remeasurement (gain) loss” line item included in “Net cash provided by operating activities of continuing operations.” The amount of this revision for the nine months ended September 30, 2012 was approximately $173.
	On September 1, 2011, the Company completed the sale of its EyeWonder LLC and subsidiaries and chors GmbH video and rich media advertising services (EyeWonder and chors) to DG FastChannel, Inc. (now Digital Generation, Inc.) (DG). The sale of EyeWonder and chors met the criteria for discontinued operations during the year ended December 31, 2011. Accordingly, the results of operations related to EyeWonder and chors have been classified as discontinued operations in all periods presented. See further discussion at Note 4.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results and outcomes may differ from those estimates.
	Recent Accounting Standards
	Recently Adopted Accounting Standard
	In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-02, which requires additional disclosures regarding the reporting of reclassifications out of accumulated other comprehensive income (loss). ASU 2013-02 requires an entity to present, either on the face of the statement where net income (loss) is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income (loss) by the respective line items of net income (loss), but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income (loss) in its entirety in the same reporting period. This guidance is effective for reporting periods beginning after December 15, 2012. The Company adopted this guidance effective January 1, 2013, and has included the additional disclosures in Note 15.
	Recently Issued Accounting Pronouncements
	In March 2013, the FASB issued ASU 2013-05, which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. The revised standard is effective for the Company for fiscal years beginning after December 15, 2013; however, early adoption is permitted. The Company does not expect adoption of this ASU to significantly impact its consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (Topic 740). ASU 2013-11 requires that unrecognized tax benefits be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except in certain circumstances. When those circumstances exist, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This ASU is effective prospectively for reporting periods beginning after December 15, 2013. Early adoption is permitted. The Company is currently evaluating the impact this ASU will have on its financial statement presentation.

	At September 30, 2013, the Company evaluated its marketable securities and noted unrealized losses were due to fluctuations in interest rates. Management does not believe any of the unrealized losses represented an other-than-temporary impairment based on its evaluation of available evidence as of September 30, 2013. The Company’s intent is to hold these investments to such time as these assets are no longer impaired.
	Expected maturities can differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties, and the Company views its available-for-sale securities as available for current operations.

Discontinued Operations	'
	4. Discontinued Operations
	On September 1, 2011, the Company completed the sale of its EyeWonder and chors rich media advertising services to DG for net proceeds of $61,000 ($66,000 gross cash proceeds less $5,000 held in escrow), plus an estimated $10,854 receivable from DG pursuant to the purchase agreement dated as of August 30, 2011 by and among the Company, DG, and Limelight Networks Germany GmbH.
	The $10,854 receivable from DG was determined by the Company based on estimated future cash payments equal to the excess of certain current assets over certain current liabilities of EyeWonder and chors as of August 30, 2011, as defined in the purchase agreement (the Net Working Capital). The Company estimated the Net Working Capital based on its determination of the current assets and current liabilities in accordance with the relevant provisions of the purchase agreement.
	Under the terms of the purchase agreement, $700 excess of cash and cash equivalents and other current assets over current liabilities was immediately payable to the Company with the remaining Net Working Capital payable as the accounts receivable of $9,600 and income tax receivable of $500 were collected.
	The following is a summary of activity related to the receivable from DG for the year ended December 31, 2012 and the nine months ended September 30, 2013 (in thousands):
	Balance, December 31, 2011	$	10,854
	Payments received from DG		(7,440	)
	Allowance for doubtful accounts receivable and other receivables adjustments		(2,060	)

	Balance, December 31, 2012	$	536
	Payments received from DG		(124	)
	Balance, September 30, 2013	$	412
	As of September 30, 2013, the Company assessed the collectability of the remaining accounts receivable balance and believes such amount is collectible. The Company expects to continue to pursue collections on all previously reserved amounts and will record any recoveries as an adjustment to income (loss) from discontinued operations.
	The sale of EyeWonder and chors meets the criteria to be reported as discontinued operations. Accordingly, the operating results of EyeWonder and chors have been reclassified to discontinued operations in the accompanying consolidated statements of operations. The Company includes only revenues and costs directly attributable to the discontinued operations, in determining income (loss) from discontinued operations, and not those attributable to the ongoing entity. Accordingly, no general corporate overhead costs have been allocated to discontinued operations.
	Operating results of discontinued operations for the three and nine months ended September 30, 2013 and 2012, respectively, are as follows (in thousands):

	In May 2010, the Company made a strategic investment in Gaikai Inc., a private cloud-based gaming technology company (Gaikai). In August 2012, Sony Computer Entertainment Inc. acquired Gaikai and the Company recorded a gain on sale of its cost basis investment in Gaikai of $9,420. The carrying value of the Gaikai cost basis investment as of the sale date was approximately $2,000. The aggregate selling price was $11,400 consisting of $10,154 of cash received and $1,237 held in escrow for a period of up to 15 months to cover any potential indemnification claims. As of September 30, 2013, the Company was not aware of any potential indemnification claims that are expected to reduce the amount received from escrow, and recorded a current receivable of approximately $1,237, which is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets as of September 30, 2013 and December 31, 2012.

	7. Goodwill and Other Intangible Assets
	The Company tests goodwill for impairment on an annual basis or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company has concluded that it has one reporting unit and has assigned the entire balance of goodwill to that reporting unit. The fair value of the reporting unit is determined using the Company’s market capitalization as of its annual impairment assessment date or each reporting date if circumstances indicate the goodwill might be impaired. Items that could reasonably be expected to negatively affect key assumptions used in estimating fair value include but are not limited to:
		•		Sustained decline in the Company’s stock price due to a decline in its financial performance due to the loss of key customers, loss of key personnel, emergence of new technologies or new competitors;
		•		Decline in overall market or economic conditions leading to a decline in its stock price; and
		•		Decline in observed control premiums paid in business combinations involving comparable companies.
	The estimated fair value of the reporting unit is determined using a market approach utilizing the Company’s market capitalization as adjusted for a control premium based on the estimated average and median control premiums of transactions involving companies comparable to the Company. As of the annual impairment testing date and at December 31, 2012, the Company determined that goodwill was not impaired. The Company noted that the estimated fair value of its reporting unit exceeded carrying value by approximately $23,000 or 10% using the market capitalization plus an estimated control premium of 40% on September 30, 2013. Based on this analysis, management believes goodwill is not impaired at September 30, 2013; however, adverse changes to certain key assumptions as described above could result in a future charge to earnings.
	Foreign currency translation adjustments increased the carrying amount of goodwill for the three and nine months ended September 30, 2013 by $165 and $380, respectively.

	Akamai Litigation
	In June 2006, Akamai Technologies, Inc. (Akamai), and the Massachusetts Institute of Technology (MIT), filed a lawsuit against the Company in the United States District Court for the District of Massachusetts alleging that the Company was infringing two patents assigned to MIT and exclusively licensed by MIT to Akamai, United States Patent No. 6,553,413 (the ’413 patent) and United States Patent No. 6,108,703 (the ’703 patent). In September 2006, Akamai and MIT expanded their claims to assert infringement of a third patent United States Patent No. 7,103,645 (the ’645 patent). Before trial, Akamai waived by stipulation its claims of indirect or induced infringement and proceeded to trial only on the theory of direct infringement. In February 2008, a jury returned a verdict in this lawsuit, finding that the Company infringed four claims of the ’703 patent at issue and rejecting the Company’s invalidity defenses. The jury awarded an aggregate of approximately $45,500 which includes lost profits, reasonable royalties and price erosion damages for the period April 2005 through December 31, 2007. In addition, the jury awarded prejudgment interest which the Company estimated to be $2,600 at December 31, 2007. The Company recorded an aggregate $48,100 as a provision for litigation as of December 31, 2007. During 2008, the Company recorded a potential additional provision of approximately $17,500 for potential additional infringement damages and interest. The total provision for litigation at December 31, 2008 was $65,600.
	On July 1, 2008, the court denied the Company’s Motions for Judgment as a Matter of Law (JMOL), Obviousness, and a New Trial. The court also denied Akamai’s Motion for Permanent Injunction as premature and its Motions for Summary Judgment regarding the Company’s equitable defenses. The court conducted a bench trial in November 2008 regarding the Company’s equitable defenses. The Company also filed a motion for reconsideration of the court’s earlier denial of the Company’s motion for JMOL. The Company’s motion for JMOL was based largely upon a clarification in the standard for a finding of joint infringement articulated by the Federal Circuit in the case of Muniauction, Inc. v. Thomson Corp., released after the court denied the Company’s initial motion for JMOL. On April 24, 2009, the court issued its order and memorandum setting aside the adverse jury verdict and ruling that the Company did not infringe Akamai’s ’703 patent and that the Company was entitled to JMOL. Based upon the court’s April 24, 2009 order, the Company reversed the $65,600 provision for litigation previously recorded for this lawsuit as the Company no longer believed that payment of any amounts represented by the litigation provision was probable. The court entered final judgment in favor of the Company on May 22, 2009, and Akamai filed its notice of appeal of the court’s decision on May 26, 2009. On December 20, 2010, the Court of Appeals for the Federal Circuit issued its opinion affirming the trial court’s entry of judgment in the Company’s favor. On February 18, 2011, Akamai filed a motion with the Court of Appeals for the Federal Circuit seeking a rehearing and rehearing en banc. On April 21, 2011, the Court of Appeals for the Federal Circuit issued an order denying the petition for rehearing, granting the petition for rehearing en banc, vacating the December 20, 2010 opinion affirming the trial court’s entry of judgment in the Company’s favor, and reinstated the appeal.
	On August 31, 2012, the Court of Appeals for the Federal Circuit issued its opinion in the case. The Court of Appeals stated that the trial court correctly determined that the Company did not directly infringe Akamai’s ’703 patent and upheld the trial court’s decision to vacate the original jury’s damages award. The Court of Appeals also held that the Company did not infringe Akamai’s ’413 or ’645 patents. A slim majority in this three-way divided opinion also announced a revised legal theory of induced infringement, remanded the case to the trial court, and gave Akamai an opportunity for a new trial to attempt to prove that the Company induced its customers to infringe Akamai’s patent under the Court of Appeals’ new legal standard. On December 28, 2012, the Company filed a petition for writ of certiorari to the United States Supreme Court to appeal this sharply divided Court of Appeals decision and sought to stay any proceedings at the trial court until the Supreme Court rules on that petition. Akamai then filed a cross petition for consideration of the Court of Appeals standard for direct infringement followed by an opposition to the Company’s petition. On June 24, 2013, the Supreme Court asked the Solicitor General to weigh in on the Company’s petition. On September 4, 2013, the Company met with the Solicitor General’s office, and on October 15, 2013, the Company filed a letter of further explanation with the Solicitor General’s office. The Company believes that the Court of Appeal’s new induced infringement standard runs counter to the Patent Act and Supreme Court precedent, and it should be overturned by the Supreme Court. Additionally, just as the Company has successfully shown that it does not directly infringe Akamai’s patent, the Company firmly believes that it will ultimately be successful in showing that it does not infringe Akamai’s patent under the Court of Appeals majority’s new induced infringement theory, and does not believe a loss is probable; therefore, no provision for this lawsuit is recorded in the consolidated financial statements.
	In light of the status of the litigation, the Company believes that there is a reasonable possibility that it has incurred a loss related to the Akamai litigation. While the Company believes that there is a reasonable possibility that a loss has been incurred, the Company is not able to estimate a range of the loss due to the complexity and procedural status of the case. The Company will continue to vigorously defend against the allegation.
	Legal and other expenses associated with this case have been significant. The Company includes these litigation expenses in general and administrative expenses as incurred, as reported in its consolidated statement of operations.
	Other Litigation
	The Company is subject to various other legal proceedings and claims, either asserted or unasserted, arising in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, management does not believe the outcome of any of these matters will have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows. Litigation relating to the content delivery services industry is not uncommon, and the Company is, and from time to time has been, subject to such litigation. No assurances can be given with respect to the extent or outcome of any such litigation in the future.
	Other Matters
	The Company is subject to indirect taxation in various states and foreign jurisdictions. Laws and regulations that apply to communications and commerce conducted over the Internet are becoming more prevalent, both in the United States and internationally, and may impose additional burdens on the Company conducting business online or providing Internet-related services. Increased regulation could negatively affect the Company’s business directly, as well as the businesses of its customers, which could reduce their demand for the Company’s services. For example, tax authorities in various states and abroad may impose taxes on the Internet-related revenue the Company generates based on regulations currently being applied to similar but not directly comparable industries.
	There are many transactions and calculations where the ultimate tax determination is uncertain. In addition, domestic and international taxation laws are subject to change. In the future, the Company may come under audit, which could result in changes to its tax estimates. The Company believes it maintains adequate tax reserves to offset potential liabilities that may arise upon audit. Although the Company believes its tax estimates and associated reserves are reasonable, the final determination of tax audits and any related litigation could be materially different than the amounts established for tax contingencies. To the extent these estimates ultimately prove to be inaccurate, the associated reserves would be adjusted, resulting in the recording of a benefit or expense in the period in which a change in estimate or a final determination is made.

Net Loss per Share	'
	13. Net Loss per Share
	The Company calculates basic and diluted earnings per weighted average share based on net income (loss). The Company uses the weighted-average number of common shares outstanding during the period for the computation of basic earnings per share. Diluted earnings per share include the dilutive effect of convertible stock options and restricted stock units in the weighted-average number of common shares outstanding. Net income (loss) from continuing operations is utilized in determining whether potential common shares are dilutive or antidilutive for purposes of computing diluted net income (loss) per share.
	The following table sets forth the components used in the computation of basic and diluted net loss per share for the periods indicated (in thousands, except per share data):
		Three Months Ended						Nine Months Ended

	Basic and diluted net loss per share	$	(0.11	)	$	(0.01	)	$	(0.31	)	$	(0.20	)
	For the three months ended September 30, 2013 and 2012, outstanding options and restricted stock units of approximately 1.4 million and 2.2 million, respectively, were excluded from the computation of diluted net loss per common share because including them would have been anti-dilutive.
	For the nine months ended September 30, 2013 and 2012, outstanding options and restricted stock units of approximately 1.7 million and 2.2 million, respectively, were excluded from the computation of diluted net loss per common share because including them would have been anti-dilutive.

	On June 6, 2013, the Company’s stockholders approved the Company’s 2013 Employee Stock Purchase Plan (ESPP). The ESPP allows participants to purchase the Company’s common stock at a 15% discount of the lower of the beginning or end of the offering period using the closing price on that day. As of September 30, 2013, no shares of common stock had been issued and approximately $74, which is included in other current liabilities had been withheld from employees for future purchases under the ESPP.

	Income taxes for the interim periods presented have been included in the accompanying consolidated financial statements on the basis of an estimated annual effective tax rate. Based on an estimated annual effective tax rate and discrete items, the income tax expense from continuing operations for the three and nine months ended September 30, 2013 was approximately $197 and $328, respectively. Income tax expense on the loss from continuing operations before taxes was different than the statutory income tax rate primarily due to the Company providing for a valuation allowance on deferred tax assets in certain jurisdictions, and the recording of state and foreign tax expense for the three and nine month periods.
	The Company files income tax returns in jurisdictions with varying statues of limitations. Tax years 2010 through 2012 generally remain subject to examination by federal and most state tax authorities. As of September 30, 2013, the Company is not under U.S. federal examination but is under examination by certain foreign and state jurisdictions for various tax years. The Company believes that its income tax filing positions and deductions related to tax periods subject to examination will be sustained upon audit and does not anticipate any adjustments that will result in a material adverse effect on the Company’s financial condition, results of operations or cash flow.
	On September 13, 2013, the Internal Revenue Service released final tangible property regulations under Sections 162(a) and 263(a) of the Internal Revenue Code of 1986 (Code), regarding the deduction and capitalization of expenditures related to tangible property. The final regulations replace temporary regulations that were issued in December 2011. Also released were proposed regulations under Section 168 of the Code regarding dispositions of tangible property. These final and proposed regulations will be effective for the Company’s year beginning January 1, 2014. Early adoption is available; however, the Company has not elected early adoption of the regulations. Transition guidance providing the procedural rules to comply with such regulations is expected to be released in the near term. The Company continues to review the regulations, but does not believe there will be a material impact on its consolidated financial statements when they are fully adopted.

Segment Reporting	'
	21. Segment Reporting
	The Company operates in one industry segment — content delivery and related services. The Company operates in three geographic areas — Americas; Europe; Middle East and Africa (EMEA); and Asia Pacific.
	Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The Company’s Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results and plans for products or components below the consolidated unit level. Accordingly, the Company reports as a single operating segment.
	Revenue by geography is based on the location of the customer from which the revenue is earned. The following table sets forth revenue and long-lived assets by geographic area (in thousands):

	During the three months ended June 30, 2013, we made reclassifications to certain customers within our geographic regions. This was primarily the result of customers relocating from one geographic region to another geographic region. For all periods presented customers are reported in their new geographic region. The impact of the customer reclassifications from previously reported amounts were as follows. For the three months ended September 30, 2012, Americas increased $577, EMEA increased $933, and Asia Pacific decreased $1,510. For the nine months ended September 30, 2013, Americas increased $607, EMEA increased $1,267, and Asia Pacific decreased $1,874. For the nine months ended September 30, 2012, Americas increased $1,167, EMEA increased $3,324, and Asia Pacific decreased $4,491.

Fair Value Measurements	'
	22. Fair Value Measurements
	The Company evaluates certain of its financial instruments within the three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:
	Level 1 — defined as observable inputs such as quoted prices in active markets;
	Level 2 — defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and
	Level 3 — defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
	As of September 30, 2013 and December 31, 2012, the Company held certain assets and liabilities that were required to be measured at fair value on a recurring basis. These include money market funds, commercial paper, corporate notes and bonds, U.S. government agency bonds, and publicly traded stocks, which are classified as either cash and cash equivalents or marketable securities.
	The Company’s financial assets are valued using market prices on both active markets (Level 1) and less active markets (Level 2). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments or identical instruments in less active markets. Level 3 inputs are valued using models that take into account the terms of the arrangement as well as multiple inputs where applicable, such as estimated units sold and other customer utilization metrics.
	The following is a summary of fair value measurements at September 30, 2013 (in thousands):
					Fair Value Measurements at Reporting Date Using

	For the nine months ended September 30, 2013, unrealized gains and losses for marketable securities are included in other comprehensive income and expense. For the nine months ended September 30, 2013, the Company had net unrealized losses of approximately $36.
	The following is a summary of fair value measurements at December 31, 2012 (in thousands):
					Fair Value Measurements at Reporting Date Using
	Description		Total		Quoted Prices		Significant		Significant
					In Active		Other		Unobservable

	Total assets measured at fair value		$	33,755	$	14,715	$	19,040	$	—
	-1	Classified in marketable securities
	-2	Classified in cash and cash equivalents
	The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. The carrying amount of short-term and long-term marketable securities represents fair value as the securities are marked to market as of each balance sheet date with any unrealized gains and losses reported in other comprehensive income and expense. The carrying amount of accounts receivable, accounts payable, and accrued liabilities approximates fair value due to the short-term maturity of the amounts.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Such interim financial information is unaudited but reflects all adjustments that, in the opinion of management, are necessary for the fair presentation of the interim periods presented. All such adjustments are, in the opinion of management, of a normal recurring nature. The results of operations presented in this Quarterly Report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any future periods. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited financial statements and footnotes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2012. All information is presented in thousands, except per share amounts and where specifically noted.
	The consolidated financial statements include accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The Company has revised the statement of cash flow presentation for certain remeasurement gains and losses from the “Effect of exchange rate changes on cash and cash equivalents” line item to the “Foreign currency remeasurement (gain) loss” line item included in “Net cash provided by operating activities of continuing operations.” The amount of this revision for the nine months ended September 30, 2012 was approximately $173.
	On September 1, 2011, the Company completed the sale of its EyeWonder LLC and subsidiaries and chors GmbH video and rich media advertising services (EyeWonder and chors) to DG FastChannel, Inc. (now Digital Generation, Inc.) (DG). The sale of EyeWonder and chors met the criteria for discontinued operations during the year ended December 31, 2011. Accordingly, the results of operations related to EyeWonder and chors have been classified as discontinued operations in all periods presented. See further discussion at Note 4.
Use of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results and outcomes may differ from those estimates.
Recent Accounting Standards	'
	Recent Accounting Standards
	Recently Adopted Accounting Standard
	In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-02, which requires additional disclosures regarding the reporting of reclassifications out of accumulated other comprehensive income (loss). ASU 2013-02 requires an entity to present, either on the face of the statement where net income (loss) is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income (loss) by the respective line items of net income (loss), but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income (loss) in its entirety in the same reporting period. This guidance is effective for reporting periods beginning after December 15, 2012. The Company adopted this guidance effective January 1, 2013, and has included the additional disclosures in Note 15.
	Recently Issued Accounting Pronouncements
	In March 2013, the FASB issued ASU 2013-05, which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. The revised standard is effective for the Company for fiscal years beginning after December 15, 2013; however, early adoption is permitted. The Company does not expect adoption of this ASU to significantly impact its consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (Topic 740). ASU 2013-11 requires that unrecognized tax benefits be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except in certain circumstances. When those circumstances exist, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This ASU is effective prospectively for reporting periods beginning after December 15, 2013. Early adoption is permitted. The Company is currently evaluating the impact this ASU will have on its financial statement presentation.
