	1. Basis of Presentation of Interim Financial Information
	The accompanying unaudited Condensed Consolidated Financial Statements of Heidrick & Struggles International, Inc. and subsidiaries (the “Company”) have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Significant items subject to estimates and assumptions include revenue recognition, allowance for doubtful accounts, interim effective tax rate, allowances for deferred tax assets, assessment of goodwill and other intangible assets for impairment, compensation accruals, stock-based compensation and contingent liabilities. Estimates are subject to a degree of uncertainty and actual results could differ from these estimates. These financial statements and notes are to be read in conjunction with the Company’s Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the SEC on March 13, 2014.

	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, 2013.
	Recent Financial Accounting Standards
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers.” The ASU requires that an entity recognizes 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 standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and is to be applied either retrospectively or cumulative effect transition method, with early application not permitted. The Company is currently evaluating the effect that this pronouncement will have on its financial statements and related disclosures. The effect is not currently known or reasonably estimable at this time.

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.

	Substantially all of the Company’s assets on the Condensed Consolidated Balance Sheet are measured at fair value on a recurring basis using Level 1 inputs except those noted in the tables above. The Level 2 assets above are fair valued using a market approach. The Level 3 liabilities are: (i) accruals for future earnout payments related to prior acquisitions, the values of which are determined based on discounted cash flow models; and (ii) 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, 2014 and December 31, 2013 based upon the short-term nature of the assets and liabilities.

	8. Acquisitions
	Scambler MacGregor Executive Search Pty Limited
	In November 2013, the Company acquired Scambler MacGregor, an Australian-based retained Executive Search boutique in the financial services industry for 1.1 million Australian dollars (equivalent to $1.0 million at June 30, 2014 and December 31, 2013, respectively) of initial consideration, pursuant to a stock purchase, which was funded from existing cash. In December 2013, the Company paid an additional $0.1 million related to the final working capital settlement. The Company also recorded $0.4 million of intangible assets and $2.7 million of goodwill. The goodwill is primarily related to the acquired workforce and strategic fit. The former owners of Scambler MacGregor are eligible to receive earnout payments of up to 2.8 million Australian dollars based on the achievement of certain revenue metrics over the period November 2013 through December 2018. As a result, the Company accrued 2.2 million Australian dollars (equivalent to $2.2 million and $2.0 million at June 30, 2014 and December 31, 2013, respectively), representing the estimated fair value of future earnout payments as of the acquisition date.
	Senn-Delaney Leadership Consulting Group, LLC
	In December 2012, the Company acquired Senn-Delaney Leadership Consulting Group, LLC, a global leader of corporate culture shaping. Under the terms of the purchase agreement, the Company paid $53.5 million at closing for 100 percent of the equity of Senn Delaney. The agreement also included additional cash consideration up to $15.0 million based on the realization of specific earnings milestones achieved over the period December 2012 through December 2015, of which $3.4 million was paid during the second quarter of 2014. The Company has accrued $9.5 million and $12.1 million at June 30, 2014 and December 31, 2013, respectively, for the remaining cash consideration. The Company has recognized $0.5 million of accretion expense included in General and administrative expenses in the three months ended June 30, 2014 and 2013, respectively, and $0.9 million and $1.0 million of accretion expense in the six months ended June 30, 2014 and 2013, respectively. The Company also holds $6.5 million in a retention escrow that will be paid to certain key executives of Senn Delaney if they remain with the Company for three years subsequent to the acquisition. The Company recognized $0.6 million and $1.2 million of compensation expense included in Salaries and employee benefits in the three and six months ended June 30, 2014 and June 30, 2013, respectively, related to the retention awards.

Derivative Instruments And Hedging Activities Disclosure [Abstract]	'
Derivative Financial Instruments	'
	10. Derivative Financial Instruments
	The Company uses derivative instruments to manage exposures to 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 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.
	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 (“Restated Credit 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 (See Note 12, Line of Credit and Term Loan). 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 swap 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 a derivative that is designated and that qualifies as a cash flow hedge is recorded in Accumulated other comprehensive income and is subsequently reclassified into earnings in the period when 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 derivative is recognized directly in earnings. During the quarter ended June 30, 2014, 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. The notional amount of the interest rate swap was $32.5 million and $35.5 million as of June 30, 2014 and December 31, 2013, respectively.
	The summary of information with respect to the interest rate swap is as follows:
			June 30,				December 31,
			2014				2013
			Fair				Fair

	12. Line of Credit and Term Loan
	On June 22, 2011, the Company and certain foreign subsidiary borrowers of the Company entered into a Credit Agreement (the “Agreement”) with its lenders. The Agreement provides the terms under which the lenders will make available to the Company a committed unsecured revolving credit facility in an aggregate amount of up to $75 million (the “Revolving Facility”). The Agreement includes an expansion feature that allows the Company to seek to increase the aggregate commitment under the Revolving Facility by up to $25 million provided that the Company is in compliance with certain conditions set forth in the Agreement. The Agreement also provides for the issuance of letters of credit. The Revolving Facility matures on June 22, 2016. Under the Agreement, the Borrowers may borrow U.S. dollars, euros, British pounds sterling, Australian dollars or other major traded currencies as agreed by the lenders. Borrowings under the Agreement bear interest, at the Company’s election, at the existing Alternate Base Rate (as defined in the Agreement) or Adjusted LIBOR Rate (as defined in the Agreement) plus a spread as determined by the Company’s leverage ratio.
	On January 31, 2013, the Company and certain foreign subsidiary borrowers of the Company entered into a Restated Credit Agreement which amended the Agreement to add a committed term loan facility in an aggregate amount of up to $40 million (the “Term Facility”). There was no other material term change in the Agreement.
	On January 31, 2013 the Company borrowed $40 million under the Term Facility. The Term Facility is being amortized over a five-year period pursuant to which the Company will make fifteen quarterly payments of $1.5 million through 2016 and quarterly payments of $2.0 million during 2017. The remaining outstanding balance of the Term Facility will be paid on January 31, 2018. The interest rate on the debt is Adjusted LIBOR plus a spread which is dependent on the Company’s leverage ratio. The Company entered into an interest rate swap to address the risk related to the fluctuation in Adjusted LIBOR (See Note 10, Derivative Financial Instruments). As of June 30, 2014 the Company’s interest rate, including the impact of the interest rate swap, was 2.54%.
	As of June 30, 2014 and December 31, 2013 there was $32.5 million and $35.5 million, respectively, outstanding under the Term Facility. There were no borrowings made under the Revolving Facility during the six months ended June 30, 2014 and for the year ended December 31, 2013. The Company was in compliance with the financial and other covenants under the Restated Credit Agreement and no event of default existed as of June 30, 2014 and for the year ended December 31, 2013, respectively.

	The Company’s 2012 Heidrick & Struggles GlobalShare Program (the “2012 Program”) provides for grants of stock options, stock appreciation rights, and other stock-based awards that are valued based upon the grant date fair value of shares. The 2012 Program originally authorized 1,300,000 shares of Common Stock for issuance pursuant to awards under the plan. These awards may be granted to directors, selected employees and independent contractors. On May 22, 2014, the stockholders of the Company approved an amendment to the 2012 Program to increase the number of shares of Common Stock reserved for issuance under the 2012 Program by 700,000 shares. As of June 30, 2014, 767,836 awards have been issued under the 2012 Program and 1,578,204 shares remain available for future awards, which includes 346,040 forfeited awards. The 2012 Program provides that no awards can be granted after May 24, 2022.
	The Company measures its stock-based compensation costs based on the grant date fair value of the awards and recognizes these costs in the financial statements over the requisite service period.
	A summary of information with respect to stock-based compensation is as follows:

	As of June 30, 2014, there was $4.8 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 3.0 years.
	Performance Stock Units
	The Company grants performance stock units to certain of its senior executives. The performance stock units are generally subject to a cliff vesting at the end of a three year period. The vesting will vary between 0%—200% based on the attainment of operating income goals over the 3 year vesting period. The performance stock units are expensed on a straight-line basis over the 3 year vesting period.
	In the first quarter of 2014, the Company granted market-based performance stock units to the Chief Executive Officer as part of his initial compensation package. The market-based awards vest after a two-year service period and if the price of the Company’s common stock exceeds specified targets. The fair value of the market-based awards was determined using the Monte-Carlo simulation model. A Monte Carlo simulation model uses stock price volatility and other variables to estimate the probability of satisfying the market conditions and the resulting fair value of the award. Compensation costs related to the market-based awards are recognized regardless of whether the market condition is satisfied, as long as the requisite service has been provided.

	The Company operates its executive search and leadership consulting services in the Americas; Europe (which includes Africa); and Asia Pacific (which includes the Middle East) and operates its culture shaping business as a separate segment.
	For segment purposes, reimbursements of out-of-pocket expenses classified as revenue and other operating income are reported separately and, therefore, are not included in the results of each segment. 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) more appropriately reflects its core operations.

	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 are substantial in amount, and some of which are covered by insurance. In accordance with ASC 450, Contingencies, the Company records a reserve for estimated losses when the loss is probable and the amount can be reasonably estimated. Based upon information currently available, the Company believes the ultimate resolution of any pending claims or 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 $6.7 million at June 30, 2014). 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.

	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers.” The ASU requires that an entity recognizes 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 standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and is to be applied either retrospectively or cumulative effect transition method, with early application not permitted. The Company is currently evaluating the effect that this pronouncement will have on its financial statements and related disclosures. The effect is not currently known or reasonably estimable at this time.
