Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies A complete listing of the Company’s significant accounting policies is discussed in Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the SEC on March 15, 2013. Recently Adopted Financial Accounting Standards On January 1, 2013 the Company adopted the Financial Accounting Standards Board’s (“FASB”) guidance to improve the reporting of reclassifications out of accumulated other comprehensive income. The guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income (See Note 14, Changes in Accumulated Other Comprehensive Income). For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. These requirements are to be applied to each component of accumulated other comprehensive income. Other than the additional disclosure, the adoption of these changes had no impact on the Condensed Consolidated Financial Statements. Recently Issued Financial Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial statements upon adoption.

Warrants and equity securities		481		501

Total	$	12,751	$	11,902

The Company’s U.S. non-qualified deferred compensation plan consists primarily of U.S. marketable securities and mutual funds, all of which are valued using Level 1 inputs (See Note 7, Fair Value Measurements). The aggregate cost basis for these investments was $9.9 million and $9.3 million as of June 30, 2013 and December 31, 2012, respectively. The warrants and equity securities primarily consist of cost method investments, none of which were evaluated for impairment since there were no triggering events in the respective periods.

Fair Value Disclosures [Abstract]

Fair Value Measurements

7. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

•

Level 1 – Quoted prices in active markets for identical assets and liabilities.

•

Level 2 – Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

•

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.


	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)			Total
At June 30, 2013
U.S. non-qualified deferred compensation plan	$	12,270	$	—		$	—		$	12,270

	$	12,270	$	24,816		$	(10,477	)	$	26,609

At December 31, 2012
U.S. non-qualified deferred compensation plan	$	11,401	$	—		$	—		$	11,401
Assets designated for retirement and pension plans		—		24,096			—			24,096

	$	11,401	$	24,026		$	(9,769	)	$	25,658

Substantially all of the Company’s assets that are measured at fair value on a recurring basis are measured using Level 1 inputs, except those noted in the table above. The Level 2 assets above are fair valued using a market approach. The Level 3 liabilities are accruals for future earnout payments related to prior acquisitions, the values of which are determined based on discounted cash flow models, and warrant and equity securities, the values of which are determined using a valuation model. The Company considers the recorded value of its financial assets and liabilities, which consist primarily of cash and cash equivalents, accounts receivable, and accounts payable, to approximate the fair value of the respective assets and liabilities at June 30, 2013 and December 31, 2012 based upon the short-term nature of the assets and liabilities.

Debt	6 Months Ended
Debt	Jun. 30, 2013
Debt Disclosure [Abstract]
Debt	10. Debt On January 31, 2013, the Company and certain foreign subsidiary borrowers of the Company entered into an Amendment and Restatement Agreement, pursuant to which the Borrowers, the Lenders and the Administrative Agent amended and restated the Credit Agreement dated June 22, 2011. Pursuant to the Agreement, the Credit Agreement was amended to add a committed term loan facility in an aggregate amount of up to $40 million (the “Term Facility”). On January 31, 2013, the Company borrowed $40 million under the Agreement. The Term Facility will be amortized over a five-year period pursuant to which the Company will make fifteen quarterly payments of $1.5 million. The first payment was made on June 28, 2013 and payments will continue on the last calendar day of every fiscal quarter, up to and including December 31, 2016. Additionally, the Company will make four payments of $2.0 million on March 31, 2017, June 30, 2017, September 30, 2017 and December 31, 2017 and a final payment of the remaining outstanding balance of the Term Facility on January 31, 2018. The interest rate on the debt is LIBOR plus a spread which is dependent on the Company’s leverage ratio and paid monthly. The Company entered into an interest rate swap to address the risk related to the fluctuation in LIBOR (See Note 11, Derivative Financial Instruments). The other material terms of the Credit Agreement (as in effect prior to the Agreement) were not amended by the Agreement. The Company is in compliance with its debt covenants as of June 30, 2013.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

11. Derivative Financial Instruments

Summary of Derivative Instruments

The Company uses derivative instruments primarily to manage exposures to foreign currency exchange rate risk and interest rate risk. The Company’s primary objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates and interest rates. The Company’s derivatives expose it to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. The Company does, however, seek to mitigate such risks by limiting its counterparties to financial institutions that meet certain criteria. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored. Management does not expect material losses as a result of defaults by counterparties.

Interest Rate Risk

The Company pays short-term variable interest rates, plus a spread which is dependent on the Company’s leverage ratio, calculated as defined within the Amendment and Restatement Agreement. The term loan exposes the Company to the variability in interest payments and therefore fluctuations in interest expense and cash flows due to changes in interest rates.

On February 28, 2013, the Company entered into an interest rate swap to hedge the variable interest rate exposure from the underlying term facility. The interest rate swap was entered into to manage fluctuations in cash flows resulting from interest rate risk attributable to changes in the short-term variable interest rate. This interest rate swap involves the exchange of variable-rate interest payments for fixed-rate interest payments based on the contractual underlying notional amount. Gains or losses on the interest rate swaps that are linked to the term loan being hedged are expected to perfectly offset the losses or gains on the underlying term loan from the short-term variable interest rate. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. If a derivative is deemed to be ineffective, the ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the quarter ended June 30, 2013, the Company’s interest rate swap entered into for purposes of managing fluctuations in cash flows resulting from the variable rate term loan was deemed effective and the Company expects it will be effective for the next twelve months. This interest rate swap was the only hedging instrument used by the Company to mitigate its interest rate risk.

The Company had the following interest rate swap in place as of June 30, 2013:


Interest Rate Swap Contract	Notional Amount		Fair Value (1)		Gain (Loss) (2)
Derivative designated as cash flow hedge	$	38,500	$	233	$	233

(1)	Included in the Condensed Consolidated Balance Sheets within Other current assets

(2)	Included in Other comprehensive loss, net of $83 thousand of tax

Foreign Exchange Risk

The Company enters into foreign exchange forward contracts to reduce the short-term effects of foreign currency fluctuations on assets and liabilities such as foreign currency receivables and payables. These derivatives are designated as fair value hedges. Gains and losses on the contracts are included in other, net and substantially offset foreign exchange gains and losses from the remeasurement of intercompany balances or other assets or liabilities denominated in currencies other than the functional currency of the reporting entity. The Company purchased $12.4 million and sold $92.8 million in contracts in the three months ended June 30, 2013 and purchased $29.4 million and sold $168.1 million in contracts in the six months ended June 30, 2013, of which $4.9 million purchased contracts and $30.2 million sold contracts are outstanding as of June 30, 2013. The Company’s largest contracts are in Euro, Australian Dollar, Brazilian Real and British Pound Sterling.

The Company had the following foreign exchange forward contracts in place as of June 30, 2013:


Foreign Exchange Forward Contract	Notional Amount (in USD Equivalent)			Fair Value (1)
Derivatives designated as fair value hedges	$	(25,255	)	$	825

(1)	Included in the Condensed Consolidated Balance sheets within Other current assets

The gain on the foreign exchange contracts was $0.8 million and $1.1 million for the three and six months ended June 30, 2013, respectively and is included in Other, net in the Condensed Consolidated Statements of Comprehensive Income (Loss).

- Definition

The entire disclosure for derivative instruments and hedging activities including, but not limited to, risk management strategies, non-hedging derivative instruments, assets, liabilities, revenue and expenses, and methodologies and assumptions used in determining the amounts.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2013
Income Tax Disclosure [Abstract]
Income Taxes	15. Income Taxes In the second quarter of 2013, the Company reported income before taxes of $5.1 million and recorded an income tax provision of $3.1 million. The Company’s effective income tax rate for the second quarter of 2013 was 61.7%, which reflects an adjusted full-year expected annualized tax rate of approximately 64 percent, up from the first quarter 2013 adjusted full-year expected annualized tax rate of approximately 58 percent. The increase in the anticipated full-year annualized tax rate from the first quarter is primarily due to a change in the projection and mix of income earned worldwide. The annualized effective tax rate is higher than the statutory rate due to the Company incurring losses in certain jurisdictions that are not benefitted for tax purposes. For the first six months of 2013, the Company reported income before taxes of $5.1 million and recorded an income tax provision of $4.4 million. The decrease in the tax rate from the first quarter was due to the impact of valuation allowances. In the second quarter of 2012, the Company reported income before taxes of $5.5 million and recorded an income tax provision of $3.6 million. The Company’s effective income tax rate for the second quarter of 2012 was 66.3%. For the first six months of 2012, the Company reported income before taxes of $10.0 million and recorded an income tax provision of $7.5 million. The Company’s effective income tax rate for the six months ended June 30, 2012 was 74.6%.

Segment Reporting [Abstract]

Segment Information

16. Segment Information

The Company operates in three geographic regions: the Americas; Europe, which includes Africa; and Asia Pacific, which includes the Middle East.

For segment purposes, reimbursements of out-of-pocket expenses classified as revenue and restructuring charges are reported separately and, therefore, are not included in the results of each geographic region. The Company believes that analyzing trends in revenue before reimbursements (net revenue), analyzing operating expenses as a percentage of net revenue, and analyzing operating income (loss) excluding restructuring charges, more appropriately reflects its core operations.

There were no restructuring charges for the first six months of 2013. By segment, restructuring charges were $0.6 million in Europe and a credit of $0.1 million in the Americas for the second quarter of 2012, and $0.8 million in Europe for the first six months of 2012.

The revenue and operating income by segment, are as follows:

Guarantees	Jun. 30, 2013
Guarantees [Abstract]
Guarantees	17. Guarantees The Company has issued cash collateralized guarantees and letter of credit backed guarantees supporting certain obligations, primarily the payment of office lease obligations for certain of its subsidiaries in Europe and Asia Pacific. The guarantees were made to secure the respective lease agreements and are for the terms of the lease agreements, which extend through 2018. For each guarantee issued, the Company would have to perform under the guarantee if the subsidiary defaults on a lease payment. The maximum amount of undiscounted payments the Company would be required to make in the event of default on all outstanding guarantees is approximately $2.3 million as of June 30, 2013. The Company has not accrued for these arrangements as no event of default exists or is expected to exist.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	18. Commitments and Contingencies The Company has contingent liabilities from various pending claims and litigation matters arising in the ordinary course of the Company’s business, some of which involve claims for damages that may be substantial in amount. Some of these matters are covered by insurance. Although the Company’s ultimate liability in the matter discussed below cannot be determined, based upon information currently available, the Company believes the ultimate resolution of such claims and litigation will not have a material adverse effect on its financial condition, results of operations or liquidity. UK Employee Benefits Trust On January 27, 2010, HM Revenue & Customs (“HMRC”) in the United Kingdom notified the Company that it was challenging the tax treatment of certain of the Company’s contributions in the United Kingdom to an Employee Benefits Trust between 2002 and 2008. HMRC alleges that these contributions should have been subject to Pay As You Earn tax and Class 1 National Insurance Contributions in the United Kingdom; and HMRC is proposing an adjustment to the Company’s payroll tax liability for the affected years. The aggregate amount of HMRC’s proposed adjustment is approximately £3.9 million (equivalent to $5.9 million at June 30, 2013). The Company has appealed the proposed adjustment. At this time, the Company believes that the likelihood of an unfavorable outcome with respect to the proposed adjustment is not probable and the potential amount of any loss cannot be reasonably estimated. The Company also believes that the amount of any final adjustment would not be material to the Company’s financial condition.

Accounting Policies [Abstract]
Recently Adopted Financial Accounting Standards	Recently Adopted Financial Accounting Standards On January 1, 2013 the Company adopted the Financial Accounting Standards Board’s (“FASB”) guidance to improve the reporting of reclassifications out of accumulated other comprehensive income. The guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income (See Note 14, Changes in Accumulated Other Comprehensive Income). For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. These requirements are to be applied to each component of accumulated other comprehensive income. Other than the additional disclosure, the adoption of these changes had no impact on the Condensed Consolidated Financial Statements.
Recently Issued Financial Accounting Standards	Recently Issued Financial Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial statements upon adoption.

- Definition

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge.
