NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(All tables in thousands, except share and per share figures)

(Unaudited)

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, 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, 2015, as filed with the SEC on March 10, 2016.

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, 2015.

Recently Issued Financial Accounting Standards

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment transactions including the income tax accounting, classification of awards as either equity or liabilities, the accounting for forfeitures and classification on the statement of cash flows. The standard is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

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 is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

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 customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for these goods or services. The effective date has been deferred for one year to the interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date, which was interim and annual reporting periods beginning after December 15, 2016. The guidance permits the use of either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

Leasehold improvements	$	41,293		$	40,583
Office furniture, fixtures and equipment	16,750			16,234
Computer equipment and software	29,666			28,648
Property and equipment, gross	87,709			85,465
Accumulated depreciation	(51,245		)	(48,967		)
Property and equipment, net	$	36,464		$	36,498

Depreciation expense for the three months ended June 30, 2016 and 2015 was $2.3 million and $1.8 million, respectively. Depreciation expense for the six months ended June 30, 2016 and 2015 was $4.6 million and $4.3 million, respectively.

5. Investments

The Company has a U.S. non-qualified deferred compensation plan that consists primarily of U.S. marketable securities and mutual funds, all of which are valued using Level 1 inputs (See Note 6, Fair Value Measurements). The fair value for these investments was $16.8 million and $14.1 million as of June 30, 2016 and December 31, 2015, respectively. The aggregate cost basis for these investments was $13.2 million and $11.1 million as of June 30, 2016 and December 31, 2015, respectively.

6. 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.

6

The following tables provide a summary of the fair value measurements at June 30, 2016 and December 31, 2015 for each major category of assets and liabilities measured at fair value on a recurring basis:

	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, 2016
U.S. non-qualified deferred compensation plan	$	16,782	$	—	$	—		$	16,782
Assets designated for retirement and pension plans	—		18,544		—			18,544
Acquisition earnout accruals	—		—		(6,197		)	(6,197		)
	$	16,782	$	18,544	$	(6,197	)	$	29,129

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Total
At December 31, 2015
U.S. non-qualified deferred compensation plan	$	14,145	$	—	$	—		$	14,145
Assets designated for retirement and pension plans	—		18,164		—			18,164
Acquisition earnout accruals	—		—		(12,033		)	(12,033		)
	$	14,145	$	18,164	$	(12,033	)	$	20,276

The Level 2 assets above are fair valued using a market approach. 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 June 30, 2016 and December 31, 2015 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 six months ended June 30, 2016.

	Acquisition Earnout Accruals
Balance at December 31, 2015	$	(12,033	)
Acquisition earnout (Note 7)	(1,454		)
Earnout accretion	(558		)
Earnout payments	7,461
Foreign currency translation	387
Balance at June 30, 2016	$	(6,197	)

On June 30, 2015, the Company entered into a Second Amended and Restated Credit Agreement (the “Restated Credit Agreement”). The Restated Credit Agreement amended and restated the Credit Agreement executed on June 22, 2011 (the “Credit Agreement”). Pursuant to the Restated Credit Agreement, the Company replaced its Revolving Facility and Term Facility (“Existing Facility”) with a single senior unsecured revolving line of credit with an aggregate commitment of up to $100 million, which includes a sublimit of $25 million for letters of credit, and a $50 million expansion feature (the “Replacement Facility”). The Replacement Facility will mature on June 30, 2020. Borrowings under the Restated Credit Agreement bear interest at the Company’s election at the existing Alternate Base Rate (as defined in the Credit Agreement) or Adjusted LIBOR Rate (as defined in the Credit Agreement) plus a spread as determined by the Company’s leverage ratio.

Borrowings under the Replacement Facility may be used for working capital, capital expenditures, Permitted Acquisitions (as defined in the Credit Agreement) and for other general corporate purposes of the Company and its subsidiaries. The obligations under the Replacement Facility are guaranteed by certain of the Company’s subsidiaries.

As of June 30, 2016 and December 31, 2015, the Company had no outstanding borrowings under the Restated Credit Agreement and the Company was in compliance with the financial and other covenants under the Restated Credit Agreement and no event of default existed.

11. 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 June 30, 2016, 1,397,410 awards have been issued under the 2012 Program and 990,794 shares remain available for future awards, which includes 388,204 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:

	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Salaries and employee benefits	$	1,506	$	1,107	$	3,337	$	2,140
General and administrative expenses	563		450		563		450
Income tax benefit related to stock-based compensation included in net income	831		626		1,568		1,042

Restricted Stock Units

Restricted stock unit activity for the six months ended June 30, 2016:

	Number of Restricted Stock Units		Weighted- Average Grant-date Fair Value
Outstanding on December 31, 2015	473,935		$	19.98
Granted	207,405		22.92
Vested and converted to common stock	(117,845	)	20.01
Forfeited	(12,178	)	22.66
Outstanding on June 30, 2016	551,317		21.02

As of June 30, 2016, there was $5.6 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.2 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 three year vesting period. The performance stock units are expensed on a straight-line basis over the three year vesting period.

In 2014, the Company granted market-based performance stock units to the Chief Executive Officer. 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. All of the market-based performance conditions were satisfied such that all 125,000 performance stock units granted to the Chief Executive Officer vested upon the completion of the two year service period in February 2016.

Performance stock unit activity for the six months ended June 30, 2016:

	Number of Performance Stock Units		Weighted- Average Grant-date Fair Value
Outstanding on December 31, 2015	272,024		$	18.28
Granted	125,388		22.98
Vested and converted to common stock	(160,600	)	15.51
Forfeited	—		—
Outstanding on June 30, 2016	236,812		22.64

As of June 30, 2016, there was $3.6 million of pre-tax unrecognized compensation expense related to unvested performance stock units, which is expected to be recognized over a weighted average of 2.2 years.

14. Segment Information

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 more appropriately reflects its core operations.

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

	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Revenue:
Executive Search and Leadership Consulting

15. 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 2018. 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 $3.1 million as of June 30, 2016. The Company has not accrued for these arrangements as no event of default exists or is expected to exist.

16. 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, including the “UK Employee Benefits Trust” matter discussed below, 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. 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 $5.2 million) at June 30, 2016. 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.

Executive Overview

Our Business. We are a leadership advisory firm providing executive search, culture shaping services and leadership consulting. We help our clients build leadership teams by facilitating the recruitment, management and development of senior executives. We provide our services to a broad range of clients through the expertise of over 300 consultants located in major cities around the world.

Executive Search. We partner with respected organizations globally to build and sustain the best leadership teams in the world, with a specialized focus on the placement of top-level senior executives. We believe focusing on top-level senior executives provides the opportunity for several advantages including access to and influence with key decision makers, increased potential for recurring search and consulting engagements, higher fees per executive search, enhanced brand visibility, and a leveraged global footprint. Working at the top of client organizations also facilitates the attraction and retention of high-caliber consultants who desire to serve top industry executives and their leadership needs.

Our executive search services are provided on a retained basis. Revenue before reimbursements of out-of-pocket expenses (“net revenue”) consists of retainers and indirect expenses billed to clients. For each assignment, we enter into a contract with our client that outlines the general terms and conditions of the assignment. Typically, we are paid a retainer for our executive search services equal to approximately one-third of the estimated first year compensation for the position to be filled. In addition, generally, if the actual compensation of a placed candidate exceeds the estimated compensation, we often are authorized to bill the client for one-third of the excess. Indirect expenses are calculated as a percentage of the retainer with certain dollar limits per search. We generally bill our clients for our retainer and indirect expenses in one-third increments over a three-month period commencing in the month of a client's acceptance of the contract.

Culture Shaping. Our culture shaping business uses its proprietary technology to analyze and interpret organizational cultures and drivers and partner with clients to administer methods that develop alignment on leadership teams and desired organizational outcomes. Culture Shaping is currently less than 10% of our net revenue. Our culture shaping services generate revenue through a combination of professional service and license fees related to the engagement. Net revenue associated with culture shaping consulting is recognized proportionally as services are performed. Net revenue associated with licenses to use culture shaping proprietary materials is typically recognized over the term of the arrangement.

Leadership Consulting. Leadership consulting works with clients to accelerate performance at the strategic, organization, team and individual leader levels. On February 29, 2016, we acquired Decision Strategies International, Inc. ("DSI"), which specializes in advising organizations and institutions on strategic planning and decision making in certain operating environments, leadership development and talent strategy. On October 1, 2015, we acquired Co Company Limited, an

13

organizational development consulting firm. Leadership Consulting is currently less than 10% of our net revenue. Our leadership consulting services generate revenue primarily through the professional fees generated for each engagement which are generally based on the size of the project and scope of services. Depending on the terms of the agreement, net revenue from leadership consulting is either recognized proportionally as services are performed or in accordance with the completion of the engagement deliverables.

Key Performance Indicators

We manage and assess Heidrick & Struggles’ performance through various means, with the primary financial and operational measures including net revenue, operating income, operating margin, Adjusted EBITDA (non-GAAP), and Adjusted EBITDA margin (non-GAAP). Executive Search and Leadership Consulting performance is also measured using consultant headcount and consultant productivity. Specific to Executive Search, confirmation trends and average revenue per search or project are used to measure performance.

Revenue is driven by market conditions and a combination of the number of executive search engagements and leadership consulting and culture shaping projects and the average revenue per search or project. With the exception of compensation expense, incremental increases in revenue do not necessarily result in proportionate increases in costs, particularly operating and administrative expenses, thus potentially improving operating margins.

The number of consultants, confirmation trends, number of searches or projects completed, productivity levels and the average revenue per search or project will vary from quarter to quarter, affecting net revenue and operating margin.

Our Compensation Model

At the Executive Search consultant level there are fixed and variable components of compensation. Individuals are rewarded for their performance based on a system that directly ties a portion of their compensation to the amount of net revenue for which they are responsible. A portion of the reward is based upon individual performance against a series of non-financial measures. Credit towards the variable portion of an Executive Search consultant’s compensation is earned by generating net revenue for winning and executing work. Each quarter, we review and update the expected annual performance of all Executive Search consultants and accrue variable compensation accordingly. The amount of variable compensation that is accrued for each Executive Search consultant is based on a tiered payout model. Overall Company performance determines the amount available for total variable compensation. The more net revenue that is generated by the consultant, the higher the percentage credited towards the consultant’s variable compensation and thus accrued by our Company as expense. The mix of individual consultants who generate the revenue can significantly affect the total amount of compensation expense recorded, which directly impacts operating margin. As a result, the variable portion of the compensation expense may fluctuate significantly from quarter to quarter. The total variable compensation is discretionary and is based on Company-wide financial targets approved by the Human Resources and Compensation Committee of the Board of Directors.

A portion of our Executive Search consultants’ and management cash bonuses is deferred and paid over a three-year vesting period. The compensation expense related to the amounts being deferred is recognized on a graded vesting attribution method over the requisite service period. This service period begins on January 1 of the respective fiscal year and continues through the deferral date, which coincides with our bonus payments in the first quarter of the following year, and for an additional three year vesting period. The deferrals are recorded in Accrued salaries and employee benefits and Other non-current liabilities in the Condensed Consolidated Balance Sheets.

Third Quarter 2016 Outlook

We are currently forecasting 2016third quarter net revenue of between $140 million and $150 million. Our 2016third quarter guidance is based upon, among other things, management’s assumptions for the anticipated volume of new executive search confirmations and leadership consulting and culture shaping projects, the current backlog, consultant productivity, consultant retention, the seasonality of our business and average currency rates in June 2016.

Our 2016 guidance is subject to a number of risks and uncertainties, including those discussed under Item 1A - Risk Factors in our 2015 Annual Report on Form 10-K. As such, actual results could vary from these projections.

Liquidity and Capital Resources

General. We continually evaluate our liquidity requirements, capital needs and availability of capital resources based on our operating needs. We believe that our available cash balances together with the funds expected to be generated from operations and funds available under our committed revolving credit facility will be sufficient to finance our operations for the foreseeable future, as well as to finance the cash payments associated with our cash dividends and stock repurchase program.

We pay the non-deferred portion of annual bonuses in the first quarter following the year in which they are earned. Employee bonuses are accrued throughout the year and are based on our performance and the performance of the individual employee.

Lines of credit. On June 30, 2015, we entered into a Second Amended and Restated Credit Agreement (the “Restated Credit Agreement”). The Restated Credit Agreement amended and restated the Credit Agreement executed on June 22, 2011 (the “Credit Agreement”). Pursuant to the Restated Credit Agreement, we replaced our Revolving Facility and Term Facility (“Existing Facility”) with a single senior unsecured revolving line of credit with an aggregate commitment of up to $100 million, which includes a sublimit of $25 million for letters of credit, and a $50 million expansion feature (the “Replacement Facility”). The Replacement Facility will mature on June 30, 2020. Borrowings under the Restated Credit Agreement bear interest at our election at the existing Alternate Base Rate (as defined in the Credit Agreement) or Adjusted LIBOR Rate (as defined in the Credit Agreement) plus a spread as determined by our leverage ratio. As of June 30, 2016, we did not have any borrowings outstanding under the Restated Credit Agreement.

We were in compliance with the financial and other covenants under the Restated Credit Agreement and no event of default existed.

Cash and cash equivalents. Cash and cash equivalents at June 30, 2016, December 31, 2015 and June 30, 2015 were $85.4 million, $190.5 million and $119.9 million, respectively. The $85.4 million of cash and cash equivalents at June 30, 2016 includes $40.6 million held by our foreign subsidiaries. A portion of the $40.6 million is considered permanently reinvested in these foreign subsidiaries. If these funds were required to satisfy obligations in the U.S., the repatriation of these funds could cause us to incur additional U.S. income taxes or foreign withholding taxes. Any additional taxes could be offset, in part or in whole, by foreign tax credits. The amount of such taxes and application of tax credits would be dependent on the income tax laws and other circumstances at the time these amounts are repatriated. Based on these variables, it is not practicable to determine the income tax liability that might be incurred if these earnings were to be repatriated.

Cash flows used in operating activities. For the six months ended June 30, 2016, cash used in operating activities was $85.0 million. This use of cash was primarily the result of a reduction in accrued expenses due to cash bonus payments of $145.0 million related to 2015 and prior year cash bonus deferrals with 2016 variable compensation accruals of $59.5 million partially offsetting these payments, an increase in accounts receivable of $30.1 million and the payment of $6.5 million for the retention bonus paid to certain key executives related to the Senn Delaney acquisition. These uses of cash were partially offset by a decrease in net other assets and liabilities of $8.1 million, net income of $8.0 million, depreciation and amortization expense of $7.6 million, stock compensation expense of $3.9 million and an increase in deferred revenue of $3.7 million.

For the six months ended June 30, 2015, cash used in operating activities was $63.1 million, principally reflecting a $48.6 million decrease in accrued expenses primarily due to cash bonus payments of approximately $113.0 million for 2014 and prior cash deferrals with 2015 variable compensation accruals of $55.1 million, increases in accounts receivables of $29.5 million and income tax payments of $3.8 million along with net income of $8.4 million.

Cash flows used in investing activities. Cash used in investing activities was $5.6 million for the six months ended June 30, 2016 primarily due to the acquisition of DSI for $9.0 million, net purchases of available for sale securities of $2.0 million and

21

capital expenditures of $1.1 million. These uses of cash were partially offset by a reduction in restricted cash of $6.5 million due to a release of funds for the retention bonus paid to certain key executives related to the Senn Delaney acquisition.

Cash used in investing activities was $11.3 million for the six months ended June 30, 2015 primarily due to capital expenditures of $10.2 million and net purchases of available for sale securities of $1.0 million. Capital expenditures primarily related to the office build out for our new Chicago office space.

Cash flows used in financing activities. Cash used in financing activities for the six months ended June 30, 2016 was $15.1 million primarily due to earnout payments of $7.5 million related to the Senn Delaney, Scambler MacGregor and Co Company acquisitions, cash dividend payments of $4.9 million and the payment of employee tax withholdings on equity transactions of $2.7 million.

Cash used in financing activities for the six months ended June 30, 2015 was $14.7 million primarily due to earnout payments of $5.5 million related to the Senn Delaney and Scambler MacGregor acquisitions, cash dividend payments of $5.0 million, debt repayment of $3.0 million and the payment of employee tax withholdings on equity transactions of $0.8 million. Also in the second quarter of 2015, the Company amended and restated its borrowing agreement wherein the prior term loan was repaid and the outstanding balance of the term loan remained outstanding under the revolver.

Off-Balance Sheet Arrangements. We do not have material off-balance sheet arrangements, special purpose entities, trading activities of non-exchange traded contracts or transactions with related parties.

Application of Critical Accounting Policies and Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our Condensed Consolidated Financial Statements, which have been prepared using accounting principles generally accepted in the United States of America. Our significant accounting policies are discussed in Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 10, 2016, and in Note 2, Summary of Significant Accounting Policies, in the Notes to Condensed Consolidated Financial Statements included in Item 1. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. If actual amounts are ultimately different from previous estimates, the revisions are included in our results of operations for the period in which the actual amounts become known.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or if changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. Management believes its critical accounting policies that reflect its more significant estimates and assumptions relate to revenue recognition, income taxes, interim effective tax rate and assessment of goodwill and other intangible assets for impairment. See Application of Critical Accounting Policies and Estimates in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2015, as filed with the SEC on March 10, 2016.

The guidance permits the use of either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Currency market risk. With our operations in the Americas, Europe and Asia Pacific, we conduct business using various currencies. Revenue earned in each country is generally matched with the associated expenses incurred, thereby reducing currency risk to earnings. However, because certain assets and liabilities are denominated in currencies other than the U.S. dollar, changes in currency rates may cause fluctuations in the valuation of such assets and liabilities. As the local currency of our subsidiaries has generally been designated as the functional currency, we are affected by the translation of foreign currency financial statements into U.S. dollars. A 10% change in the average exchange rate for currencies of all foreign countries in which we operate would have increased or decreased our net income for the six months ended June 30, 2016 by $0.2 million. For financial information by geographic segment, see Note 14, Segment Information, in the Notes to Condensed Consolidated Financial Statements.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures as defined in the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) Rule 13a-15(e) and 15d-15(e), that are designed to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Any system of controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Management of the Company, with the participation of the principal executive officer and the principal financial officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of June 30, 2016. Based on the evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2016.

(b) Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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, 2015, as filed with the SEC on March 10, 2016.

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, 2015.

Recently Issued Financial Accounting Standards

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment transactions including the income tax accounting, classification of awards as either equity or liabilities, the accounting for forfeitures and classification on the statement of cash flows. The standard is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

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 is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

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 customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for these goods or services. The effective date has been deferred for one year to the interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date, which was interim and annual reporting periods beginning after December 15, 2016. The guidance permits the use of either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 June 30, 2016 and December 31, 2015 for each major category of assets and liabilities measured at fair value on a recurring basis:

	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, 2016
U.S. non-qualified deferred compensation plan	$	16,782	$	—	$	—		$	16,782
Assets designated for retirement and pension plans	—		18,544		—			18,544

	$	16,782	$	18,544	$	(6,197	)	$	29,129

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Total
At December 31, 2015
U.S. non-qualified deferred compensation plan	$	14,145	$	—	$	—		$	14,145
Assets designated for retirement and pension plans	—		18,164		—			18,164

	$	14,145	$	18,164	$	(12,033	)	$	20,276

The Level 2 assets above are fair valued using a market approach. 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 June 30, 2016 and December 31, 2015 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 six months ended June 30, 2016.

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 June 30, 2016, 1,397,410 awards have been issued under the 2012 Program and 990,794 shares remain available for future awards, which includes 388,204 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:

	Three Months Ended June 30,				Six Months Ended June 30,

As of June 30, 2016, there was $5.6 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.2 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 three year vesting period. The performance stock units are expensed on a straight-line basis over the three year vesting period.

In 2014, the Company granted market-based performance stock units to the Chief Executive Officer. 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. All of the market-based performance conditions were satisfied such that all 125,000 performance stock units granted to the Chief Executive Officer vested upon the completion of the two year service period in February 2016.

Performance stock unit activity for the six months ended June 30, 2016:

	Number of Performance Stock Units		Weighted- Average Grant-date Fair Value
Outstanding on December 31, 2015	272,024		$	18.28

Segment Information

Segment Information

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 more appropriately reflects its core operations.

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

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 2018. 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 $3.1 million as of June 30, 2016.

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, including the “UK Employee Benefits Trust” matter discussed below, 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. 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 $5.2 million) at June 30, 2016. 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.

Recent Financial Accounting Standards

Recently Issued Financial Accounting Standards

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment transactions including the income tax accounting, classification of awards as either equity or liabilities, the accounting for forfeitures and classification on the statement of cash flows. The standard is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

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 is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

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 customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for these goods or services. The effective date has been deferred for one year to the interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date, which was interim and annual reporting periods beginning after December 15, 2016. The guidance permits the use of either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.
