Accounting Policies [Abstract]
Basis of Presentation of Interim Financial Information	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, income taxes, interim effective tax rate and assessment of goodwill and other intangible assets for impairment. 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, 2016, as filed with the SEC on March 23, 2017.

Accounting Policies [Abstract]

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, 2016.

Recently Issued Financial Accounting Standards

In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-09, Compensation - Stock Compensation, Scope of Modification Accounting, which is intended to provide clarity and reduce both diversity in practice, cost and complexity when implementing a change in the terms or conditions of a share-based payment award. ASU 2017-09 requires that an entity should account for the effects of a modification unless the fair value, vesting conditions, and whether the award is classified as a liability instrument or an equity instrument remain unchanged in the modification. ASU 2017-09 is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company will adopt this guidance effective January 1, 2018. The impact of this accounting guidance will be dependent on future modification events including the number of awards modified.

In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost, which is intended to improve the consistency, transparency and usefulness of net benefit cost disclosures. ASU 2017-07 requires that an employer report the service cost component of net benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Additionally, the other components of net benefit costs are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. ASU 2017-07 is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company will adopt this guidance effective January 1, 2018. The impact of this accounting guidance will not be material to the Company's financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other, which eliminates Step 2 from the goodwill impairment test. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The Company early adopted ASU 2017-04, during the three months ended June 30, 2017. The Company concluded that ASU 2017-04 is preferable to the current guidance included in ASC 350 due to the simplified process of subsequently measuring goodwill.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows. The Company currently does not include restricted cash amounts in the beginning and ending cash amounts and will change the presentation of the cash flow statement to include restricted cash in the beginning and ending cash totals. The standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted.The Company will adopt this guidance effective January 1, 2018. If the Company had adopted the guidance as of September 30, 2017, the beginning and ending balance of cash, cash equivalents and restricted cash for the three months ended September 30, 2017 would have each increased by $0.6 million in the Condensed Consolidated Statement of Cash Flows.

In August 2016, the Financial Accounting Standards Board ("FASB") issued accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, which is intended to reduce diversity in practice as to how certain cash receipts and cash payments should be presented and classified. The standard is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company has evaluated the standard and noted the guidance for contingent consideration payments made after a business combination are applicable to the Condensed Consolidated Statements of Cash Flows. The Company currently classifies all contingent consideration payments as financing activities. The impact of this change is not expected to be significant to the classification of these activities on the Consolidated Statement of Cash Flows.

In February 2016, the FASB issued ASU No. 2016-02, Leases, intended to improve financial reporting about leasing transactions. The new guidance will require entities that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations created by those leases and to disclose key information about the leasing arrangements. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. The guidance requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities, which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments including the recognition of unrealized changes in fair value within net income. The standard is effective for annual reporting periods beginning after December 15, 2017. The Company will adopt this guidance effective January 1, 2018 and is currently evaluating the impact of this accounting guidance.

In May 2014, the FASB issued 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 these goods or services. The guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The guidance permits the use of either of the following transition methods: (i) a full retrospective method reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective method with the cumulative effect upon initial adoption recognized at the date of initial application (modified retrospective). The Company will adopt the guidance on January 1, 2018 and will apply the modified retrospective method, which involves recognizing the cumulative effect of applying the guidance at the date of initial application with no restatement of the comparative periods presented.

The Company is performing its evaluation of ASU No. 2014-09. The Company is paid a retainer for its executive search services equal to approximately one-third of the estimated first year compensation for the position to be filled. If the actual compensation of a placed candidate exceeds the estimated compensation, the Company is often authorized to bill the client for one-third of the excess. The Company currently recognizes revenue associated with the difference between the estimated compensation and actual compensation at the time this amount is considered fixed and determinable. Under ASU 2014-09, the difference between estimated compensation and actual compensation is considered variable consideration. The Company will be required to estimate the amount of variable consideration for its executive search services at contract inception. The Company is still evaluating the financial impact of this change and if other changes will be required.

The Company is continuing to evaluate the impacts of adoption of this guidance and its preliminary assessments are subject to change.

Reclassifications

Certain prior year amounts have been recast as a result of the change in the Company's operating segments as first reported in the Company's Annual Report on Form 10-K filed on March 23, 2017. The reclassifications had no impact on net income, net cash flows or stockholders' equity.

Earnings per Common Share

Basic earnings per common share is computed by dividing net income by weighted average common shares outstanding for the year. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. Common equivalent shares are excluded from the determination of diluted earnings per share in periods in which they have an anti-dilutive effect.

The following table sets forth the computation of basic and diluted earnings per share:

Fair Value Disclosures [Abstract]

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.

The following tables provide a summary of the fair value measurements at September 30, 2017 and December 31, 2016 for each major category of assets and liabilities measured at fair value on a recurring basis:

The Level 2 assets above are reinsurance contracts fair valued in accordance with BaFin - German Federal Financial Supervisory Authority guidelines, which utilize observable inputs including mortality tables and discount rates. The Level 3 liabilities include accruals for future earnout payments related to prior acquisitions, the values of which are determined based on discounted cash flow models. 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 September 30, 2017 and December 31, 2016 based upon the short-term nature of the assets and liabilities.

The following table provides a reconciliation of the beginning and ending balance of Level 3 assets and liabilities for the nine months ended September 30, 2017.

Acquisitions	Sep. 30, 2017
Business Combinations [Abstract]
Acquisitions	Acquisitions On October 1, 2015, the Company acquired Co Company, a UK-based management consulting firm that specializes in organizational development. The former owners of Co Company were eligible to receive additional cash consideration upon the realization of specific revenue and EBITDA Margin milestones achieved over the period October 2015 through December 2018. On August 25, 2016, the Company and the former owners of Co Company entered into a Deed of Amendment (the "Amendment") to the Share Purchase Agreement dated October 1, 2015. The Amendment adjusted the target fee revenue and targeted EBITDA margin for each remaining earn out period taking into consideration the unanticipated acquisitions completed subsequent to the Share Purchase Agreement. The new targets include subsequent acquisitions and took effect retrospectively from January 1, 2016. On June 14, 2017, the Company and the former owners of Co Company entered into an Earn Out Buyout Agreement (the “Buyout Agreement”) in accordance with the terms and conditions of the Share Purchase Agreement dated October 1, 2015, as amended by a Deed of Amendment dated August 25, 2016. Pursuant to the Buyout Agreement, in accordance with the Share Purchase Agreement and Deed of Amendment, the Company exercised its right to buy out all of the remaining earnout amounts. The price paid to buy out the Remaining Earn Out Amounts was calculated in accordance with the formula set forth in the Purchase Agreement and resulted in an aggregate buyout payment to the former owners of Co Company of $2.3 million during the three months ended June 30, 2017. On September 1, 2016, the Company acquired substantially all of the assets of Philosophy IB, LLP ("Philosophy IB"), a New Jersey-based leadership, organization development and management consulting firm for $6.0 million, which was funded from existing cash. The former owners of Philosophy IB are eligible to receive an additional cash consideration based on two components: achieving revenue milestones generated from its software products from September 2016 through August 2019 and percentage of consulting revenue achieved over the period September 2016 to August 2019, subject to a profitability test. During the three months ended September 30, 2017, the Company determined that the software and consulting revenue targets for the period from September 2016 to August 2017, or first installment, would not be achieved. As such, the Company reduced the first installment earnout accrual by $0.7 million.

In 2017, the Culture Shaping business continued the transition of senior-level personnel which began in 2016, primarily due to planned retirements. The Company has experienced lower than expected consultant productivity during the transition period. Also, the marketplace for culture shaping services has become increasingly more competitive and the business experienced lengthening sales cycles and decision processes within target client organizations. These events led to a decline in the revenue performance of the business and uncertainty around the timing of improving such performance. As a result, the Company identified a triggering event and performed an interim impairment evaluation on the goodwill related to its Culture Shaping reporting unit during the three months ended June 30, 2017.

During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of its Culture Shaping reporting unit. The discounted cash flow approach is dependent on a number of factors, including estimates of future market growth and trends, forecasted revenue and costs, capital investments, appropriate discount rates, certain assumptions to allocate shared costs, assets and liabilities, historical and projected performance of the reporting unit, and the macroeconomic conditions affecting each of the Company’s reporting units. The assumptions used in the determination of fair value were (1) a forecast of growth in the near and long term; (2) the discount rate; (3) working capital investments; and (4) other factors.

The Company early adopted ASU No. 2017-04, Intangibles - Goodwill and Other in conjunction with its impairment evaluation during the three months ended June 30, 2017. Under the adopted guidance, Step 2 of the goodwill impairment test is eliminated. Instead, the goodwill impairment test is completed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying value of a the reporting unit exceeds its carrying amount, however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit.

Based on the results of the of the impairment evaluation, the Company determined that the goodwill within the Culture Shaping reporting unit was impaired, which resulted in an impairment charge of $29.3 million to write-off all of the goodwill. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statement of Comprehensive Income (Loss) for the nine months ended September 30, 2017. The impairment was non-cash in nature and did not affect our current liquidity, cash flows, borrowing capability or operations; nor did it impact the debt covenants under our credit agreement.

The Company continues to monitor potential triggering events for its other reporting units including changes in the business climate in which it operates, the Company’s market capitalization compared to its book value, and the Company’s recent operating performance. Any changes in these factors could result in an impairment charge for the Company's reporting units.

The Company’s other intangible assets, net by segment, are as follows:

Culture Shaping	—		10,902
Total other intangible assets, net	$	7,236	$	20,690

As discussed above, the Culture Shaping business was impacted by the transition of senior-level personnel, primarily due to planned retirements, and the Company experienced lower than expected consultant productivity. The Company has also experienced lengthening sales cycles and decision processes within target client organizations. Due to the impact of these events on revenue and earnings when compared to actual and forecasted results, and the impact to the revenue and earnings inputs utilized in the fair value assessment of the intangible assets, the Company identified a triggering event for its Culture Shaping intangible assets and performed an impairment evaluation during the three months ended June 30, 2017.

The analysis was conducted in accordance with accounting guidance on fair value measurements taking into consideration Level 3 inputs, primarily consisting of discounted cash flow and replacement cost methodologies. Based on this evaluation, the Company recorded an impairment charge related to its Culture Shaping client relationships, trade name, software and non-compete intangible assets of $9.9 million during the nine months ended September 30, 2017. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statement of Comprehensive Income (Loss) for the nine months ended September 30, 2017.

The carrying amount of amortizable intangible assets and the related accumulated amortization are as follows:

Stock-based Compensation

Stock-Based Compensation

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. These awards may be granted to directors, selected employees and independent contractors. The 2012 Program originally authorized 1,300,000 shares of Common Stock for issuance pursuant to awards under the plan.

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 September 30, 2017, 1,744,266 awards have been issued under the 2012 Program and 790,225 shares remain available for future awards, which includes 534,491 forfeited awards. The 2012 Program provides that no awards can be granted after May 24, 2022.

In September 2017, the Company entered into an agreement with its former Chief Executive Officer pursuant to which Mr. Wolstencroft voluntarily agreed, with the concurrence of the Board of Directors, to forfeit 100 percent of his 2017 restricted stock unit and performance stock unit grants. Mr. Wolstencroft remains eligible to continue vesting in 100 percent of his 2014 sign-on restricted stock unit grant, without proration, subject to his continued service on the board through the future scheduled vesting dates. With respect to his outstanding 2015 and 2016 restricted stock unit and performance stock unit grants, Mr. Wolstencroft remains eligible to earn an agreed upon pro-rata portion of the tranches scheduled to vest in 2017, 2018 and 2019, subject to his continued service as a director through the scheduled vesting dates (and with the performance goals for performance stock unit deemed to have been achieved at target level performance), and he agreed to forfeit the remaining portions of such 2015 and 2016 restricted stock unit and performance stock unit awards.

The effective tax rate for the nine months ended September 30, 2017 was impacted by the non-deductibility of the employee benefit tax settlement (See Note 16, Commitments and Contingencies), the deferred tax effect on the long-lived assets and goodwill impairment and the inability to recognize losses in certain jurisdictions. The effective tax rate for the nine months ended September 30, 2016 was impacted by the mix of income. The Company estimates that its effective tax rate for the year ended December 31, 2017 will be approximately 8%. The full year effective rate for 2017 is primarily the result of a loss before income taxes due to the goodwill impairment and losses that cannot be benefited for tax purposes.

Segment Reporting [Abstract]

Segment Information

The Company operates its executive search business in the Americas; Europe (which includes Africa); and Asia Pacific (which includes the Middle East) and operates its leadership consulting and culture shaping businesses as separate segments.

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 more appropriately reflects its core operations.

The revenue and operating income (loss) by segment are as follows:

Guarantees	9 Months Ended
Guarantees	Sep. 30, 2017
Guarantees [Abstract]
Guarantees	Guarantees The Company has issued cash collateralized bank guarantees and letter of credit backed bank guarantees supporting certain obligations, primarily the payment of office lease obligations and business license requirements for certain of its subsidiaries in Europe and Asia Pacific. The bank guarantees were made to secure the respective agreements and are for the terms of the agreements, which extend through 2019. For each bank 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 $2.6 million as of September 30, 2017. The Company has not accrued for these arrangements as no event of default exists or is expected to exist.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Sep. 30, 2017
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation 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. Some of these matters are covered by insurance. 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 March 31, 2017, the Company reached a settlement with Her Majesty’s Revenue and Customs (“HMRC”) in the United Kingdom regarding HMRC’s challenge of the tax treatment of certain of the Company’s contributions in the United Kingdom to an Employee Benefits Trust between 2002 and 2008. HMRC alleged that the contributions should have been subject to Pay As You Earn tax and Class 1 National Insurance Contributions in the United Kingdom. In connection with the settlement, the Company agreed to pay approximately £5.4 million (equivalent to $6.8 million on the settlement date) related to Pay as You Earn tax, Class 1 National Insurance Contributions, inheritance tax and interest. Concurrently with the HMRC settlement, the Company also reached an agreement with the beneficiaries under the Employee Benefits Trust for the reimbursement of approximately £2.3 million (equivalent to $2.9 million on the settlement date) beneficiary-owed Pay as You Earn tax and Class 1 National Insurance Contributions. The Company has recorded $1.5 million related to the Pay as You Earn tax and Class 1 National Insurance Contributions and the respective beneficiary reimbursements as a component of Salaries and employee benefits in the Condensed Consolidated Statement of Comprehensive Income for the nine months ended September 30, 2017. Inheritance tax and interest expense of $2.4 million incurred as a result of the settlement is recorded as a component of Other, net in the Condensed Consolidated Statement of Comprehensive Income for the nine months ended September 30, 2017. During the three months ended June 30, 2017, the Company made payments of approximately £5.4 million (equivalent to $6.9 million on the payment date) related to the Pay as You Earn tax, and received reimbursement of £2.0 million (equivalent to $2.6 million on the reimbursement date) from the beneficiaries under the Employee Benefits Trust. Approximately £0.3 million (equivalent to $0.4 million at September 20, 2017) of reimbursements related to beneficiary-owed Pay as You Earn tax is outstanding at September 30, 2017.
