NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

(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 the assessment of goodwill, other intangible assets and long-lived assets for impairment. Estimates are subject to a degree of uncertainty and actual results could differ from these estimates. In the opinion of management, all adjustments necessary to fairly present the financial position of the Company at June 30, 2023 and December 31, 2022, the results of operations for the three and six months ended June 30, 2023 and 2022 and its cash flows for the six months ended June 30, 2023 and 2022 have been included and are of a normal, recurring nature except as otherwise disclosed. 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, 2022, as filed with the SEC on February 27, 2023.

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, 2022.

Revenue Recognition

See Note 3, Revenue.

Cost of Services

Cost of services consists of third-party contractor costs related to the delivery of various services in the Company's On-Demand Talent and Heidrick Consulting operating segments.

Research and Development

Research and development (“R&D”) expense consists of payroll, employee benefits, stock-based compensation, other employee expenses and third-party professional fees associated with the development of new technologies to enhance existing products and services and to expand the range of the Company's offerings. The benefits from the Company's R&D efforts are intended to be utilized to develop and enhance new and existing services and products across the Company's current offerings in Executive Search, Heidrick Consulting and On-Demand Talent, and for products and services in new segments that the Company may embark upon in the future from time to time.

Marketable Securities

The Company’s marketable securities consist of available-for-sale debt securities with original maturities exceeding three months.

Restricted Cash

The following table provides a reconciliation of the cash and cash equivalents between the Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Cash Flows as of June 30, 2023 and 2022, and December 31, 2022 and 2021:

	June 30,				December 31,
	2023		2022		2022		2021
Cash and cash equivalents	$	217,776	$	336,634	$	355,447	$	545,225
Restricted cash included within other non-current assets	41		16		42		34
Total cash, cash equivalents and restricted cash	$	217,817	$	336,650	$	355,489	$	545,259

Earnings per Common Share

Basic earnings per common share are computed by dividing net income by weighted average common shares outstanding for the period. 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:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Net income	$	8,982	$	24,149	$	24,568	$	42,616
Weighted average shares outstanding:
Basic	20,010		19,726		19,958		19,675
Effect of dilutive securities:
Restricted stock units	516		455		584		608
Performance stock units	111		133		159		202
Diluted	20,637		20,314		20,701		20,485
Basic earnings per share	$	0.45	$	1.22	$	1.23	$	2.17
Diluted earnings per share	$	0.44	$	1.19	$	1.19	$	2.08

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating Lease Right-of-Use Assets, Operating Lease Liabilities - Current and Operating Lease Liabilities - Non-Current in the Company's Condensed Consolidated Balance Sheets. The Company does not have any leases that meet the finance lease criteria.

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made in advance and any accrued rent expense balances. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components. For office leases, the Company accounts for the lease and non-lease components as a single lease component. For equipment leases, such as vehicles and office equipment, the Company accounts for the lease and non-lease components separately.

Goodwill

Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. These circumstances include a significant change in business climate, attrition of key personnel, changes in financial condition or results of operations, prolonged decline in the Company’s stock price and market capitalization, competition, and other factors.

The goodwill impairment test compares the fair value of a reporting unit to its carrying amount, including goodwill. The Company operates five reporting units: Americas, Europe (which includes Africa), Asia Pacific (which includes the Middle East), On-Demand Talent and Heidrick Consulting. The fair value of each of the Company’s reporting units is determined using a discounted cash flow methodology. An impairment charge is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit.

On October 31, 2022, the Company conducted its annual goodwill impairment evaluation, which indicated that the carrying value of the Heidrick Consulting reporting unit was less than its fair value. During the three months ended June 30, 2023, the Company acquired businessfourzero and recorded approximately $7.1 million of goodwill in the Heidrick Consulting reporting unit. Due to the inclusion of goodwill in a reporting unit with a pre-existing fair value shortfall, the Company evaluated the recent and anticipated future financial performance of the Heidrick Consulting reporting unit and determined that it was more likely than not that the fair value of the reporting unit was less than its carrying value. As a result, the Company identified a triggering event and performed an interim goodwill impairment evaluation during the three months ended June 30, 2023.

During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. 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; (4) macroeconomic conditions and (5) other factors.

Based on the results of the impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million to write-off all of the associated goodwill. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2023, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2023. The impairment was non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations; nor did it impact the debt covenants under the Company's credit agreement.

Recently Issued Financial Accounting Standards

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance is intended to provide temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is effective March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2024. The Company is currently evaluating the impact of this accounting guidance. The new guidance is not expected to have a material effect on the Company's financial statements.

3.    Revenue

Executive Search

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Generally, each executive search contract contains one performance obligation which is the process of identifying potentially qualified candidates for a specific client position. In most contracts, the transaction price includes both fixed and variable consideration. Fixed compensation is comprised of a retainer, equal to approximately one-third of the estimated first year compensation for the position to be filled, and indirect expenses, equal to a specified percentage of the retainer, as defined in the contract. The Company generally bills clients for the 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. If actual compensation of a placed candidate exceeds the original compensation estimate, the Company is often authorized to bill the client for one-third of the excess compensation. The Company refers to this additional billing as uptick revenue. In most contracts, variable consideration is comprised of uptick revenue and direct expenses. The Company bills its clients for uptick revenue upon completion of the executive search, and direct expenses are billed as incurred.

The Company estimates uptick revenue at contract inception, based on a portfolio approach, utilizing the expected value method based on a historical analysis of uptick revenue realized in the Company’s geographic regions and industry practices, and initially records a contract’s uptick revenue in an amount that is probable not to result in a significant reversal of cumulative revenue recognized when the actual amount of uptick revenue for the contract is known. Differences between the estimated and actual amounts of variable consideration are recorded when known. The Company does not estimate revenue for direct expenses as it is not materially different than recognizing revenue as direct expenses are incurred.

Revenue from executive search engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance.  Revenue from executive search engagements is recognized over the expected average period of performance, in proportion to the estimated personnel time incurred to fulfill the obligations under the executive search contract. Revenue is generally recognized over a period of approximately six months.

The Company's executive search contracts contain a replacement guarantee which provides for an additional search to be completed, free of charge except for expense reimbursements, should the candidate presented by the Company be hired by the client and subsequently terminated by the client for performance reasons within a specified period of time. The replacement guarantee is an assurance warranty, which is not a performance obligation under the terms of the executive search contract, as the Company does not provide any services under the terms of the guarantee that transfer benefits to the client in excess of assuring that the identified candidate complies with the agreed-upon specifications. The Company accounts for the replacement guarantee under the relevant warranty guidance in Accounting Standards Codification 460 - Guarantees.

On-Demand Talent

The Company enters into contracts with clients that outline the general terms and conditions of the assignment to provide on-demand consultants for various types of consulting projects, which consultants may be independent contractors or temporary employees. The consideration the Company expects to receive under each contract is dependent on the time-based fees specified in the contract. Revenue from on-demand engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. The Company has applied the practical expedient to recognize revenue for these services in the amount to which the Company has a right to invoice the client, as this amount corresponds directly with the value provided to the client for the performance completed to date. For transactions where a third-party contractor is involved in providing the services to the client, the Company reports the revenue and the related direct costs on a gross basis as it has determined that it is the principal in the transaction. The Company is primarily responsible for fulfilling the promise to provide consulting services to its clients and the Company has discretion in establishing the prices charged to clients for the consulting services and is able to contractually obligate the independent service provider to deliver services and deliverables that the Company has agreed to provide to its clients.

Heidrick Consulting

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Heidrick Consulting enters into contracts with clients that outline the general terms and conditions of the assignment to provide succession planning, executive assessment, top team and board effectiveness and culture shaping programs. The consideration the Company expects to receive under each contract is generally fixed. Most of the Company's consulting contracts contain one performance obligation, which is the overall process of providing the consulting service requested by the client. The majority of the Company's consulting revenue is recognized over time utilizing both input and output methods. Contracts that contain coaching sessions, training sessions or the completion of assessments are recognized using the output method as each session or assessment is delivered to the client. Contracts that contain general consulting work are recognized using the input method utilizing a measure of progress that is based on time incurred on the project.

The Company enters into enterprise agreements with clients to provide a license for online access, via the Company's Culture Connect platform, to training and other proprietary material related to the Company's culture shaping programs. The consideration the Company expects to receive under the terms of an enterprise agreement is comprised of a single fixed fee. The enterprise agreements contain multiple performance obligations, the delivery of materials via Culture Connect and material rights related to options to renew enterprise agreements at a significant discount. The Company allocates the transaction price to the performance obligations in the contract on a stand-alone selling price basis. The stand-alone selling price for the initial term of the enterprise agreement is outlined in the contract and is equal to the price paid by the client for the agreement over the initial term of the contract. The stand-alone selling price for the options to renew, or material right, are not directly observable and must be estimated. This estimate is required to reflect the discount the client would obtain when exercising the option to renew, adjusted for the likelihood that the option will be exercised. The Company estimates the likelihood of renewal using a historical analysis of client renewals. Access to Culture Connect represents a right to access the Company’s intellectual property that the client simultaneously receives and consumes as the Company performs under the agreement, and therefore the Company recognizes revenue over time. Given the continuous nature of this commitment, the Company utilizes straight-line ratable revenue recognition over the estimated subscription period as the Company's clients will receive and consume the benefits from Culture Connect equally throughout the contract period. Revenue related to client renewals of enterprise agreements is recognized over the term of the renewal, which is generally twelve months. Enterprise agreements do not comprise a significant portion of the Company's revenue.

Contract Balances

Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities are classified as current due to the nature of the Company's contracts, which are completed within one year. Contract assets are included within Other current assets on the Condensed Consolidated Balance Sheets.

Unbilled receivables: Unbilled receivables represents contract assets from revenue recognized over time in excess of the amount billed to the client and the amount billed to the client is solely dependent upon the passage of time. This amount includes revenue recognized in excess of billed Executive Search retainers, Heidrick Consulting fees, and On-Demand Talent fees.

Contract assets: Contract assets represent revenue recognized over time in excess of the amount billed to the client, and the amount billed to the client is not solely subject to the passage of time. This amount primarily includes revenue recognized for upticks and contingent placement fees in executive search contracts.

Deferred revenue: Contract liabilities consist of deferred revenue, which is equal to billings in excess of revenue recognized.

10

The following table outlines the changes in the contract asset and liability balances from December 31, 2022 to June 30, 2023:

	June 30, 2023		December 31, 2022		Change
Contract assets
Unbilled receivables, net	$	18,387	$	13,940	$	4,447
Contract assets	18,194		21,348		(3,154)
Total contract assets	36,581		35,288		1,293
Contract liabilities
Deferred revenue	$	44,102	$	43,057	$	1,045

During the six months ended June 30, 2023, the Company recognized revenue of $34.2 million that was included in the contract liabilities balance at the beginning of the period. The amount of revenue recognized during the six months ended June 30, 2023 from performance obligations partially satisfied in previous periods as a result of changes in the estimates of variable consideration was $14.4 million.

Each of the Company's contracts has an expected duration of one year or less. Accordingly, the Company has elected to utilize the available practical expedient related to the disclosure of the transaction price allocated to the remaining performance obligations under its contracts. The Company has also elected the available practical expedients related to adjusting for the effects of a significant financing component and the capitalization of contract acquisition costs. The Company charges and collects from its clients sales tax and value added taxes as required by certain jurisdictions. The Company has made an accounting policy election to exclude these items from the transaction price in its contracts.

4.    Credit Losses

The Company is exposed to credit losses primarily through the provision of its executive search, consulting, and on-demand talent services. The Company’s expected credit loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of clients' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of amount of accounts receivable that may not be collected is primarily based on historical loss-rate experience. When required, the Company adjusts the loss-rate methodology to account for current conditions and reasonable and supportable expectations of future economic and market conditions. The Company generally assesses future economic conditions for a period of sixty to ninety days, which corresponds with the contractual life of its accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for clients that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of clients' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

The activity in the allowance for credit losses on the Company's trade receivables is as follows:

Balance at December 31, 2022	$	6,643
Provision for credit losses	3,703
Write-offs	(3,373)
Foreign currency translation	6
Balance at June 30, 2023	$	6,979

11

There were no investments with unrealized losses at June 30, 2023. At December 31, 2022, the fair value and unrealized losses on available for sale debt securities, aggregated by investment category and the length of time the security has been in an unrealized loss position, are as follows:

	Less Than 12 Months				Balance Sheet Classification
Balance at December 31, 2022	Fair Value		Unrealized Loss		Cash and Cash Equivalents		Marketable Securities
U.S. Treasury securities	$	194,056	$	56	$	11,918	$	182,138

The unrealized loss on one investment in U.S. Treasury securities at December 31, 2022 was caused by fluctuations in market interest rates. The contractual cash flows of these investments are guaranteed by an agency of the U.S. government. Accordingly, it is expected that the investments would not be settled at a price less than the amortized cost basis. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before the recovery of the amortized cost basis.

5.    Property and Equipment, net

The components of the Company’s property and equipment are as follows:

	June 30, 2023		December 31, 2022
Leasehold improvements	$	42,253	$	40,829
Office furniture, fixtures and equipment	14,662		14,322
Computer equipment and software	34,645		30,085
Property and equipment, gross	91,560		85,236
Accumulated depreciation	(58,230)		(55,029)
Property and equipment, net	$	33,330	$	30,207

Depreciation expense for the three months ended June 30, 2023 and 2022 was $2.2 million and $1.8 million, respectively. Depreciation expense for the six months ended June 30, 2023 and 2022 was $4.2 million and $3.6 million, respectively.

6.    Leases

The Company's lease portfolio is comprised of operating leases for office space and equipment. The majority of the Company's leases include both lease and non-lease components, which the Company accounts for differently depending on the underlying class of asset. Certain of the Company's leases include one or more options to renew or terminate the lease at the Company's discretion. Generally, the renewal and termination options are not included in the right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates the renewal and termination options and when they are reasonably certain of exercise, includes the renewal or termination option in the lease term.

As most of the Company's leases do not provide an implicit interest rate, the Company utilizes an incremental borrowing rate based on the information available at the commencement date of the lease in determining the present value of lease payments. The Company has a centrally managed treasury function and, therefore, a portfolio approach is applied in determining the incremental borrowing rate. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a fully collateralized basis over a similar term in an amount equal to the total lease payments in a similar economic environment.

Office leases have remaining lease terms that range from less than one year to 10.1 years, some of which also include options to extend or terminate the lease. Most office leases contain both fixed and variable lease payments. Variable lease costs consist primarily of rent escalations based on an established index or rate and taxes, insurance, and common area or other maintenance costs, which are paid based on actual costs incurred by the lessor. The Company has elected to utilize the available practical expedient to not separate lease and non-lease components for office leases.

12

Equipment leases, which are comprised of vehicle and office equipment leases, have remaining terms that range from less than one year to 5.0 years, some of which also include options to extend or terminate the lease. The Company's equipment leases do not contain variable lease payments. The Company separates the lease and non-lease components for its equipment leases. Equipment leases do not comprise a significant portion of the Company's lease portfolio.

Lease cost components included within General and administrative expenses in the Condensed Consolidated Statements of Comprehensive Income were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Operating lease cost	$	4,567	$	4,485	$	9,092	$	8,843
Variable lease cost	3,071		$	1,472	4,987		2,633
Total lease cost	$	7,638	$	5,957	$	14,079	$	11,476

Supplemental cash flow information related to the Company's operating leases is as follows for the six months ended June 30:

7.    Financial Instruments and Fair Value

Cash, Cash Equivalents and Marketable Securities

The Company's investments in marketable debt securities, which consist of U.S. Treasury bills, are classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument's underlying contractual maturity date. Unrealized gains and losses on marketable debt securities classified as available-for-sale are recognized in Accumulated other comprehensive income (loss) in the Condensed Consolidated Balance Sheets until realized.

Investments, Assets Designated for Retirement and Pension Plans and Associated Liabilities

The Company has a U.S. non-qualified deferred compensation plan that consists primarily of U.S. marketable securities and mutual funds. The aggregate cost basis for these investments was $35.5 million and $29.1 million as of June 30, 2023 and December 31, 2022, respectively.

The Company also maintains a pension plan for certain current and former employees in Germany. The pensions are individually fixed Euro amounts that vary depending on the function and the eligible years of service of the employee. The Company’s investment strategy is to support its pension obligations through reinsurance contracts. The BaFin—German Federal Financial Supervisory Authority—supervises the insurance companies and the reinsurance contracts. The BaFin requires each reinsurance contract to guarantee a fixed minimum return. The Company’s pension benefits are fully reinsured by group insurance contracts with ERGO Lebensversicherung AG, and the group insurance contracts are measured in accordance with BaFin guidelines (including mortality tables and discount rates) which are considered Level 2 inputs.

(3)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.

(4)    In accordance with Subtopic 350-20, goodwill with a carrying value of $7.2 million was written down to its implied fair value of zero, resulting in the revised total goodwill of $198.6 million and an impairment charge of $7.2 million in earnings.

Contingent Consideration and Compensation

The former owners of the Company's acquired businesses are eligible to receive contingent consideration or additional cash compensation based on the attainment of certain operating metrics or performance criteria in the periods subsequent to acquisition. Contingent consideration and compensation are valued using significant inputs that are not observable in the market, which are defined as Level 3 inputs pursuant to fair value measurement accounting. The Company determines the fair value of contingent consideration and compensation using discounted cash flow models.

The following table provides a reconciliation of the beginning and ending balance of Level 3 liabilities for the six months ended June 30, 2023:

	Earnout		Contingent Compensation
Balance at December 31, 2022	$	(36,010)	$	(8,192)

Earnout accruals of zero and $36.0 million were recorded within Other current liabilities as of June 30, 2023 and December 31, 2022, respectively, and earnout accruals of $37.3 million and zero were recorded within Other non-current liabilities as of June 30, 2023 and December 31, 2022, respectively. Contingent compensation accruals of $7.3 million and $1.5 million are recorded within current Accrued salaries and benefits as of June 30, 2023 and December 31, 2022, respectively, and contingent compensation accruals of $7.2 million and $6.7 million are recorded within non-current Accrued salaries and benefits as of June 30, 2023 and December 31, 2022, respectively.

Goodwill

Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. During the three months ended June 30, 2023, an interim goodwill impairment evaluation was conducted to determine the fair value of the Company's goodwill. Goodwill is valued using significant inputs that are not observable in the market which are defined as Level 3 inputs pursuant to fair value measurement accounting. The Company determines the fair value of goodwill using discounted cash flow models.

The following table provides a reconciliation of the beginning and ending balance of Level 3 assets for the six months ended June 30, 2023:

	Goodwill

8.    Acquisitions

On February 1, 2023, the Company acquired Atreus Group GmbH ("Atreus"), a leading provider of executive interim management in Germany. The Company paid $33.4 million in the first quarter of 2023, with a subsequent estimated payment of between $9.0 million and $13.0 million to be paid in 2023 upon the completion of Atreus' statutory audit for the year ended December 31, 2022, for all of the outstanding equity of Atreus. The former owners of Atreus are eligible to receive additional cash consideration, which the Company estimated on the acquisition date to be between $30.0 million and $40.0 million, based on the achievement of certain revenue and operating income milestones for the period from the acquisition date through 2025. When estimating the present value of future cash consideration, the Company accrued an estimated $32.0 million as of the acquisition date for the earnout liability. The Company recorded an estimated $11.3 million for customer relationships, $6.9 million for software, $2.5 million for a trade name and $59.5 million of goodwill. Goodwill is primarily related to the acquired workforce and strategic fit and is not deductible for tax purposes. The consideration transferred was allocated on a preliminary basis to the assets acquired and liabilities assumed on their estimated fair values at the date of acquisition. The measurement period for purchase price allocation ends when information on the facts and circumstances becomes available, not to exceed twelve months, and the Company expects to finalize its measurements for the acquisition during the third quarter of 2023 pending the completion of the statutory audit. As of June 30, 2023, the allocations remain preliminary with regard to customer relationships, software, trade name, goodwill and earnout liability.

On April 1, 2023, the Company acquired businessfourzero, a next generation consultancy specializing in developing and implementing purpose-driven change. In connection with the acquisition, the Company paid $9.5 million in the second quarter of 2023 with a subsequent estimated working capital settlement of approximately $2.0 million to be paid in the third quarter of 2023. The former owners of businessfourzero are eligible to receive additional cash consideration, which the Company estimated on the acquisition date to be between $4.0 million and $8.0 million, to be paid in 2026 based on the achievement of certain revenue and operating income metrics for the period from the acquisition date through 2025. When estimating the present value of future cash consideration, the Company accrued an estimated $4.3 million as of the acquisition date for the earnout liability. The Company recorded an estimated $3.5 million for customer relationships, $0.5 million for a trade name, and $7.1 million of goodwill. The consideration transferred was allocated on a preliminary basis to the assets acquired and liabilities assumed on their estimated fair values at the date of acquisition. The measurement period for purchase price allocation ends when information on the facts and circumstances becomes available, not to exceed twelve months, and the Company expects to finalize its measurements for the acquisition during the third quarter of 2023. As of June 30, 2023, the allocations remain preliminary with regard to customer relationships, trade name, goodwill and earnout liability.

In February 2023, the Company acquired Atreus and recorded an estimated $59.5 million of goodwill related to the acquisition in the On-Demand Talent operating segment. In April 2023, the Company acquired businessfourzero and recorded an estimated $7.1 million of goodwill related to the acquisition in the Heidrick Consulting operating segment.

On October 31, 2022, the Company conducted its annual goodwill impairment evaluation, which indicated that the carrying value of the Heidrick Consulting reporting unit was less than its fair value. During the three months ended June 30, 2023, the Company acquired businessfourzero and recorded approximately $7.1 million of goodwill in the Heidrick Consulting reporting unit. Due to the inclusion of goodwill in a reporting unit with a pre-existing fair value shortfall, the Company evaluated the recent and anticipated future financial performance of the Heidrick Consulting reporting unit and determined that it was more likely than not that the fair value of the reporting unit was less than its carrying value. As a result, the Company identified a triggering event and performed an interim goodwill impairment evaluation during the three months ended June 30, 2023.

During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. 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; (4) macroeconomic conditions and (5) other factors.

Based on the results of the impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million to write-off all of the associated goodwill. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2023, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2023.. The impairment was non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations, nor did it impact the debt covenants under the Company's credit agreement.

11.    Line of Credit

On February 24, 2023, the Company entered into the Second Amendment (the “Second Amendment”) to the Credit Agreement, dated as of October 26, 2018 (the “Credit Agreement” and, as amended by the First Amendment to Credit Agreement, dated as of July 13, 2021, and the Second Amendment, the "Amended Credit Agreement") by and among the Company, Bank of America, N.A., as administrative agent, and the lenders party thereto. The Second Amendment replaced the interest rate benchmark, from the London Interbank Offered Rate (“LIBOR”) to the Secured Overnight Financing Rate (“SOFR”). At the Company's option, borrowings under the Amended Credit Agreement will bear interest at one-, three- or six-month Term SOFR, or an alternate base rate as set forth in the Amended Credit Agreement, in each case plus an applicable margin. Additionally, the Second Amendment provided the Company with a committed unsecured revolving credit facility in an aggregate amount of $200 million, increased from $175 million as set forth in the Credit Agreement, which includes a sublimit of $25 million for letters of credit and a sublimit of $10 million for swingline loans, with a $75 million expansion feature. Other than the foregoing, the material terms of the Amended Credit Agreement remain unchanged. The Amended Credit Agreement matures on July 13, 2026.

Borrowings under the Amended Credit Agreement may be used for working capital, capital expenditures, permitted acquisitions, restricted payments and for other general corporate purposes of the Company and its subsidiaries. The obligations under the Amended Credit Agreement are guaranteed by certain of the Company’s subsidiaries.

As of June 30, 2023 and December 31, 2022, the Company had no outstanding borrowings. The Company was in compliance with the financial and other covenants under the Amended Credit Agreement and no event of default existed.

12.    Stock-Based Compensation and Common Stock

On May 25, 2023, the stockholders of the Company approved an amendment to the Company's Third Amended and Restated 2012 Heidrick & Struggles GlobalShare Program (as so amended, the "Fourth A&R Program") to increase the number of shares of common stock reserved for issuance under the 2012 program by 1,060,000 shares. The Fourth A&R Program provides for grants of stock options, stock appreciation rights, restricted stock units, performance stock units, and other stock-based compensation awards that are valued based upon the grant date fair value of the awards. These awards may be granted to directors, selected employees and independent contractors.

As of June 30, 2023, 4,158,627 awards have been issued under the Fourth A&R Program, including 771,055 forfeited awards, and 1,022,428 shares remain available for future awards. The Fourth A&R Program provides that no awards can be granted after May 25, 2033.

The Company measures its stock-based compensation costs based on the grant date fair value of the awards and recognizes these costs 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,
	2023		2022		2023		2022
Salaries and benefits (1)	$	806	$	1,274	$	3,403	$	4,178
General and administrative expenses	810		810		810		810
Income tax benefit related to stock-based compensation included in net income	445		568		1,160		1,358

(1) Includes $0.7 million and $2.1 million of income related to cash-settled restricted stock units for the three months ended June 30, 2023 and 2022, respectively and $0.1 million of expense and $2.8 million of income related to cash-settled restricted stock units for the six months ended June 30, 2023 and 2022, respectively.

Restricted Stock Units

Restricted stock units are subject to ratable vesting over a three-year or four-year period dependent upon the terms of the individual grant. Compensation expense related to service-based restricted stock units is recognized on a straight-line basis over the vesting period.

Non-employee directors of the Board of Directors may elect to receive restricted stock units or shares of common stock annually pursuant to the Fourth A&R Program as part of their annual compensation. Based on their respective elections, the Company issued 16,134 and 11,850 restricted stock units for services provided by the non-employee directors during the three months ended June 30, 2023 and 2022, respectively. Restricted stock units issued to non-employee directors remain unvested until the non-employee director retires from the Board of Directors.

Restricted stock unit activity for the six months ended June 30, 2023 is as follows:

	Number of Restricted Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2022	728,285	$	31.97
Granted	268,741	26.90
Vested and converted to common stock	(171,420)	33.07
Forfeited	(12,423)	31.30
Outstanding on June 30, 2023	813,183	$	30.08

As of June 30, 2023, there was $10.8 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.6 years.

Performance Stock Units

The Company grants performance stock units to certain of its senior executives. The performance stock units are generally subject to cliff vesting at the end of a three-year period. The vesting will vary between 0% and 200% based on the attainment of certain performance and market conditions over the three-year vesting period. Half of the award is based on the achievement of operating margin thresholds and half of the award is based on the Company's total shareholder return, relative to a peer group. The fair value of the awards subject to total shareholder return metrics is 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 performance conditions and the resulting fair value of the award. The performance stock units are expensed on a straight-line basis over the three-year vesting period.

Performance stock unit activity for the six months ended June 30, 2023 is as follows:

	Number of Performance Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2022	260,452	$	40.02
Granted	103,916	34.14
Vested and converted to common stock	(124,743)	31.51
Forfeited	—	—
Outstanding on June 30, 2023	239,625	$	41.91

As of June 30, 2023, there was $5.6 million of pre-tax unrecognized compensation expense related to unvested performance stock units, which is expected to be recognized over a weighted average of 2.0 years.

Phantom Stock Units

Phantom stock units are grants of phantom stock with respect to shares of the Company's common stock that are settled in cash and are subject to various restrictions, including restrictions on transferability, vesting and forfeiture provisions. Shares of phantom stock that do not vest for any reason will be forfeited by the recipient and will revert to the Company.

Phantom stock units are subject to vesting over a period of four years, and such vesting is subject to certain other conditions, including continued service to the Company. As a result of the cash-settlement feature of the awards, the Company classifies the awards as liability awards, which are measured at fair value at each reporting date and the vested portion of the award is recognized as a liability to the extent that the service condition is deemed probable. The fair value of the phantom stock awards on the balance sheet date is determined using the closing share price of the Company's common stock on that date.

The Company recorded phantom stock-based compensation income of $0.7 million and $2.1 million during the three months ended June 30, 2023 and 2022, respectively and $0.1 million of expense and $2.8 million of income related to phantom stock units during the six months ended June 30, 2023 and 2022, respectively.

Phantom stock unit activity for the six months ended June 30, 2023 is as follows:

	Number of Phantom Stock Units
Outstanding on December 31, 2022	321,155
Granted	—
Vested	—
Forfeited	(9,775)
Outstanding on June 30, 2023	311,380

As of June 30, 2023, there was $1.4 million of pre-tax unrecognized compensation expense related to unvested phantom stock units, which is expected to be recognized over a weighted average of 2.6 years.

Common Stock

Based on their respective elections, the Company issued 16,134 and 11,850 shares of common stock for services provided by the non-employee directors during the three months ended June 30, 2023 and 2022, respectively.

On February 11, 2008, the Company's Board of Directors authorized management to repurchase shares of the Company's common stock with an aggregate purchase price of up to $50 million (the "Repurchase Authorization"). From time to time and as business conditions warrant, the Company may purchase shares of its common stock on the open market or in negotiated or block trades. No time limit has been set for completion of this program. During the three months ended June 30, 2023, the Company purchased 36,000 shares of common stock for $0.9 million. There were no purchases of shares of common stock in 2022 and prior to the 2023 purchase, the most recent purchase of the Company's shares of common stock occurred during the year ended December 31, 2012. As of June 30, 2023, the Company has purchased 1,074,670 shares of its common stock

16.    Segment Information

The Company has five operating segments. The Executive Search business operates in the Americas, Europe (which includes Africa) and Asia Pacific (which includes the Middle East), and the Heidrick Consulting and On-Demand Talent businesses operate globally.

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 reflect its core operations.

Revenue and operating income by segment are as follows:

17.    Guarantees

The Company has utilized letters of credit to support certain obligations, primarily for its office lease agreements. The letters of credit were made to secure the respective agreements and are for the terms of the agreements, which extend through 2033. For each letter of credit issued, the Company would have to use cash to fulfill the obligation if there is a default on a payment. The maximum amount of undiscounted payments the Company would be required to make in the event of default on all outstanding letters of credit is approximately $4.4 million as of June 30, 2023. The Company has not accrued for these arrangements as no event of default exists or is expected to exist.

The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements. Forward-looking statements are not historical facts or guarantees of future performance, but instead represent only our beliefs, assumptions, expectations, estimates, forecasts and projections regarding future events, many of which, by their nature, are inherently uncertain and outside our control. Forward-looking statements may be identified by the use of words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “outlook,” “projects,” “forecasts,” and similar expressions. These statements include statements other than historical information or statements of current condition and may relate to our future plans and objectives and results.

In response to working remotely, our Executive Search teams employed Heidrick Connect to operate effectively and efficiently while engaging virtually with our clients. Additionally, we have introduced upgrades to Heidrick Connect, resulting in greater flexibility, increased productivity and the ability to deliver more insights to our clients.

The executive search industry consists of several thousand executive search firms worldwide. Executive search firms are generally separated into two broad categories: retained search and contingency search. Retained executive search firms fulfill their clients’ senior leadership needs by identifying potentially qualified candidates and assisting clients in evaluating and assessing these candidates. Retained executive search firms generally are compensated for their services regardless of whether the client employs a candidate identified by the search firm and are generally retained on an exclusive basis. Typically, retained executive search firms are paid a retainer for their services equal to approximately one-third of the estimated first year compensation for the position to be filled. In addition, if the actual compensation of a placed candidate exceeds the estimated compensation, executive search firms often are authorized to bill the client for one-third of the excess. In contrast, contingency search firms are compensated only upon successfully placing a recommended candidate.

We are a retained executive search firm. Our search process typically consists of the following steps:

•Analyzing the client’s business needs in order to understand its organizational structure, relationships and culture, advising the client as to the required set of skills and experiences for the position, and identifying with the client the other characteristics desired of the successful candidate;

•Selecting, contacting, interviewing and evaluating candidates on the basis of experience and potential cultural fit with the client organization;

•Presenting confidential written reports on the candidates who potentially fit the position specification;

•Scheduling a mutually convenient meeting between the client and each candidate;

•Completing reference checks on the final candidate selected by the client; and

•Assisting the client in structuring compensation packages and supporting the successful candidate’s integration into the client team.

We also remain focused on the diversification of our revenue streams beyond our executive search business. In addition to organic expansion efforts, on February 1, 2023, we acquired Atreus, a leading provider of executive interim management in Germany, allowing us to establish and grow our on-demand talent presence in continental Europe. On April 1, 2023, we acquired businessfourzero, a next generation consultancy specializing in developing and implementing purpose-driven change, which complements our existing culture shaping practice to offer a broader, more robust set of leadership advisory solutions.

Key Performance Indicators

We manage and assess our performance through various means, with 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 Heidrick Consulting performance is also measured using consultant headcount. Specific to Executive Search, confirmation trends, consultant productivity and average revenue per search are used to measure performance. Productivity is measured by annualized Executive Search net revenue per consultant.

Revenue is driven by market conditions and a combination of the number of executive search engagements and consulting projects and the average revenue per search or project. With the exception of compensation expense and cost of services, incremental increases in revenue do not necessarily result in proportionate increases in costs, particularly operating and administrative expenses, thus creating the potential to improve 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 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 may be based upon individual performance against a series of non-financial measures. Credit towards the variable portion of a 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 consultants and accrue variable compensation accordingly. The amount of variable compensation that is accrued for each 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 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.

Historically, a portion of the Company’s consultant and management cash bonuses were deferred and paid over a three-year vesting period. The portion of the bonus was approximately 15% depending on the employee’s level or position. The compensation expense related to the amounts being deferred was recognized on a graded vesting attribution method over the requisite service period. This service period began on January 1 of the respective fiscal year and continued through the deferral date, which coincided with the Company’s bonus payments in the first half of the following year and for an additional three-year vesting period. The deferrals are recorded in Accrued salaries and benefits within both Current liabilities and Non-current liabilities in the Consolidated Balance Sheets.

In 2020, the Company terminated the cash bonus deferral for consultants and, in 2021, terminated the cash bonus deferral for management. The Company now pays 100% of the cash bonuses earned by consultants and management in the first half of

25

the following year. Consultant and management cash bonuses earned prior to 2020 and 2021, respectively, will continue to be paid under the terms of the cash bonus deferral program. The deferrals are recorded in Accrued salaries and benefits within both Current liabilities and Non-current liabilities in the Consolidated Balance Sheets. The final cash bonus deferrals were paid during the six months ended June 30, 2023.

Third Quarter 2023 Outlook

The Company expects 2023 third quarter consolidated net revenue of between $245 million and $265 million, which reflects typical summer seasonality, while acknowledging that continued fluidity in external factors, such as foreign exchange and interest rate environments, foreign conflicts, inflation and macroeconomic constraints on pricing actions may impact quarterly results. In addition, this outlook is based on the average currency rates in June 2023 and reflects, among other factors, management's assumptions for the anticipated volume of new Executive Search confirmations, On-Demand Talent projects, and Heidrick Consulting assignments, consultant productivity, consultant retention, and the seasonality of the business, along with the current backlog.

The Company's 2023 third quarter guidance is subject to a number of risks and uncertainties, including those discussed under Item 1A - Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2022, as updated in our subsequent quarterly reports on Form 10-Q and in our other filings with the SEC. As such, actual results could vary from these projections.

Three Months Ended June 30, 2023 Compared to the Three Months Ended June 30, 2022

Total revenue. Consolidated total revenue decreased $27.3 million, or 9.1%, to $273.8 million for the three months ended June 30, 2023, from $301.1 million for the three months ended June 30, 2022. The decrease in total revenue was primarily due to the decrease in revenue before reimbursements (net revenue).

Revenue before reimbursements (net revenue). Consolidated net revenue decreased $27.5 million, or 9.2%, to $271.2 million for the three months ended June 30, 2023, from $298.7 million for the three months ended June 30, 2022. Foreign exchange rate fluctuations negatively impacted results by $0.6 million, or 0.2%. Executive Search net revenue was $206.8 million for the three months ended June 30, 2023, a decrease of $47.1 million, or 18.6%, compared to the three months ended June 30, 2022. The decrease in Executive Search net revenue was primarily due to a decrease in the volume of executive search confirmations. On-Demand Talent net revenue was $39.2 million for the three months ended June 30, 2023, an increase of $16.9 million, or 75.5%, compared to the three months ended June 30, 2022. The increase in On-Demand Talent revenue was primarily due to the acquisition of Atreus Group GmbH ("Atreus") in February 2023, partially offset by a decrease in the volume of legacy on-demand projects. Heidrick Consulting net revenue was $25.2 million for the three months ended June 30, 2023, an increase of $2.8 million, or 12.3%, compared to the three months ended June 30, 2022. The increase in Heidrick Consulting revenue was primarily due to the acquisition of businessfourzero in April 2023, partially offset by a decrease in leadership assessment and development consulting engagements compared to the prior year.

The number of Executive Search and Heidrick Consulting consultants was 423 and 89, respectively, as of June 30, 2023, compared to 388 and 66, respectively, as of June 30, 2022.

Fixed compensation increased $18.8 million due to base salaries and payroll taxes, the deferred compensation plan, separation, and retirement and benefits, partially offset by a decrease in stock compensation. The increase in base salaries and payroll taxes was primarily due to the acquisitions of Atreus and businessfourzero. Variable compensation decreased $47.6 million due to lower bonus accruals related to decreased consultant productivity. Foreign exchange rate fluctuations positively impacted results by $0.3 million, or 0.2%.

For the three months ended June 30, 2023, we had an average of 2,246 employees compared to an average of 1,978 employees for the three months ended June 30, 2022.

The increase in general and administrative expenses was due to intangible amortization, office occupancy, information technology, taxes and licenses, and the acquisition of Atreus and businessfourzero, partially offset by a decrease in business development travel. Foreign exchange rate fluctuations positively impacted results by less than $0.1 million, or 0.1%.

As a percentage of net revenue, general and administrative expenses were 14.9% for the three months ended June 30, 2023, compared to 11.8% for the three months ended June 30, 2022.

As a percentage of net revenue, cost of services was 9.3% for the three months ended June 30, 2023, compared to 5.8% for the three months ended June 30, 2022.

Research and development. Due to the rapid pace of technological advances and digital disruption many of our clients are experiencing, we believe our ability to compete successfully depends increasingly upon our ability to provide clients with timely and relevant technology-enabled products and services. As such, we are focused on developing new technologies to enhance existing products and services, and to expand the range of our offerings through research and development (“R&D”), licensing of intellectual property and acquisition of third-party businesses and technology. The results of our R&D efforts will be utilized to develop and enhance new and existing services and products across our current offerings in Executive Search, Heidrick Consulting and On-Demand Talent, and for products and services in new segments that we may embark upon in the future from time to time, such as our new digital product Heidrick Navigator which we are beta testing. Consolidated R&D expense increased $1.1 million, or 24.5%, to $5.7 million for the three months ended June 30, 2023, from $4.5 million for the three months ended June 30, 2022. R&D expense consists of payroll, employee benefits, stock-based compensation other employee expenses and third-party professional fees associated with new product development.

Impairment charges. On October 31, 2022, the Company conducted its annual goodwill impairment evaluation, which indicated that the carrying value of the Heidrick Consulting reporting unit was less than its fair value. During the three months ended June 30, 2023, the Company acquired businessfourzero and recorded approximately $7.1 million of goodwill in the Heidrick Consulting reporting unit. Due to the inclusion of goodwill in a reporting unit with a pre-existing fair value shortfall, the Company evaluated the recent and anticipated future financial performance of the Heidrick Consulting reporting unit and determined that it was more likely than not that the fair value of the reporting unit was less than its carrying value. As a result, the Company identified a triggering event and performed an interim goodwill impairment evaluation during the three months ended June 30, 2023. Based on the results of the of the impairment evaluation, the Company recorded an impairment charge of $7.2 million in Heidrick Consulting to write-off all of the goodwill associated with that reporting unit. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statement of Comprehensive Income for the three months ended June 30, 2023, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30,

28

2023. 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.

Operating income. Consolidated operating income was $13.6 million for the three months ended June 30, 2023, including impairment charges of $7.2 million, compared to $33.9 million for the three months ended June 30, 2022. Foreign exchange rate fluctuations negatively impacted operating income by $0.4 million, or 1.2%.

Net non-operating income. Net non-operating income was $3.3 million for the three months ended June 30, 2023, compared to $1.1 million for the three months ended June 30, 2022.

Interest, net, was $1.9 million of income for the three months ended June 30, 2023, compared to $0.3 million for the three months ended June 30, 2022, primarily due to higher interest rates on a higher volume of short-term investments.

Other, net, was $1.4 million of income for the three months ended June 30, 2023, compared to $0.8 million for the three months ended June 30, 2022. The income in the current year is primarily due to unrealized gains on the deferred compensation plan compared to unrealized losses in the prior period. The Company's investments, including those held in the Company’s deferred compensation plan, are recorded at fair value.

Income taxes. See Note 14, Income Taxes.

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, funds expected to be generated from operations and funds available under our committed revolving credit facility will be sufficient to finance our operations for at least the next 12 months and 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 half of the year 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 February 24, 2023, the Company entered into the Second Amendment (the “Second Amendment”) to the Credit Agreement, dated as of October 26, 2018 (the “Credit Agreement” and, as amended by the First Amendment to Credit Agreement, dated as of July 13, 2021, and the Second Amendment, the "Amended Credit Agreement") by and among the Company, Bank of America, N.A., as administrative agent, and the lenders party thereto. The Second Amendment replaced the interest rate benchmark, from the London Interbank Offered Rate (LIBOR) to the Secured Overnight Financing Rate (“SOFR”). At the Company's option, borrowings under the Amended Credit Agreement will bear interest at one-, three- or six-month Term SOFR, or an alternate base rate as set forth in the Amended Credit Agreement, in each case plus an applicable margin. Additionally, the Second Amendment provided the Company with a committed unsecured revolving credit facility in an aggregate amount of $200 million, increased from $175 million as set forth in the Credit Agreement, which includes a sublimit of $25 million for letters of credit and a sublimit of $10 million for swingline loans, with a $75 million expansion feature. Other than the foregoing, the material terms of the Amended Credit Agreement remain unchanged. The Amended Credit Agreement matures on July 13, 2026.

Borrowings under the Amended Credit Agreement may be used for working capital, capital expenditures, permitted acquisitions, restricted payments and for other general corporate purposes of the Company and its subsidiaries. The obligations under the Amended Credit Agreement are guaranteed by certain of the Company’s subsidiaries.

Cash used in operating activities was $290.1 million for the six months ended June 30, 2023, primarily reflecting a decrease in accrued expenses of $274.8 million and an increase in accounts receivable of $60.0 million, partially offset by net income net of non-cash charges of $49.8 million.

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, 2022 as filed with the SEC on February 27, 2023, 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.

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 by approximately $0.2 million for the six months ended June 30, 2023. For financial information by segment, see Note 16, 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”), Rules 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 SEC 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, 2023. 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, 2023.

(b) Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting as defined in the Exchange Act Rules 13a-15(f) and 15d-15(f) that occurred during the three months ended June 30, 2023 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As of June 22, 2023 (the “Grant Date”), the Company has granted [XXX] Restricted Stock Units (“RSUs”) to the Participant as set forth herein.

The Participant agrees to be bound by all terms and conditions of the Agreement and the Program, and has received and reviewed a copy of the Program and the Prospectus for the Program dated June 14, 2023.

The RSUs granted under this Agreement shall not become valid or enforceable unless and until the Participant executes the Agreement and it is accepted by the Company.

    Title:    Chief Legal Officer & Corporate Secretary

NOW, THEREFORE, in consideration of the agreements of the Participant herein provided and pursuant to the Program, the parties agree as follows:

1.Definitions. All capitalized terms used herein, unless specifically defined herein, shall have the same meanings as established in the Program.

2.Participation. Contingent upon the execution of the Agreement, the Company hereby grants to the Participant [XXX] RSUs subject to the terms and conditions herein.

3.Vesting of RSUs.

a.Subject to Section 3(b) and Section 4 below, all RSUs granted under the Agreement shall vest in accordance with the schedule set forth below; provided the Participant has been in Continuous Service through each vesting date. Except as set forth in Section 3(b), upon the Participant’s termination of Continuous Service prior to the vesting date, the terms of Section 10 shall apply. For purposes of the Agreement, “Continuous Service” shall mean the Participant’s service with the Company or any Subsidiary or Affiliate as an employee has not been interrupted or terminated, and shall include any period during which the Participant is on an approved leave of absence from the Company or its Subsidiaries or Affiliates.

Vesting Date	Number of Shares Vesting
June 22, 2024	[XX]
June 22, 2025	[XX]
June 22, 2026	[XX]

b.If the Participant’s Continuous Service is terminated as a result of the Participant’s death or Disability, all RSUs granted to the Participant under the Agreement will immediately vest.

4.Effect of Vesting.

a.If, and at the time, the Participant’s RSUs vest under the terms of Section 3 or Section 8, and subject to Section 7, such Participant shall receive as full consideration for the RSUs a number of Shares equal to the number of RSUs which vested on such date.

b.The RSUs granted to the Participant shall be maintained in a bookkeeping account with the custodian appointed by the Human Resources & Compensation Committee (the “Committee”) from time to time (the “Custodian”) for such Participant if and until the RSUs are converted into Shares pursuant to this Section 4, at which time the Shares shall be issued to the Participant in accordance with Section 5 below.

5.Compensation Recovery. The Participant’s RSUs are subject to the Clawback Policy adopted by the Board of Directors.

6.Delivery of Shares to the Participant. As soon as practicable after the RSUs vest and are converted into Shares, and subject to Section 8, the Custodian shall, without transfer or issue tax or other incidental expense to the Participant, deliver to the Participant by first-class insured mail addressed to the Participant at the address shown on page 1 or the last address of record on file with the Custodian, (i) a statement from the Custodian referencing the number of Shares held in the Participant’s name in a book entry account,

    - 2 -    

or (ii) at the Participant’s request, certificate(s) for the number of Shares as to which the Shares vested. In any event, Shares due to the Participant shall be delivered as described above no later than March 15 of the year following the calendar year in which such RSUs vest.

7.Dividend Equivalents. The Company shall credit the Participant’s RSU account with an amount equal to the dividends, if any, that would be paid with respect to the unvested RSUs as if the RSUs were actual Shares to a shareholder as of the record date. Such amount shall be credited to the Participant’s RSU account at the same time dividends are paid with respect to the Shares, shall be subject to the vesting and forfeiture provisions set forth in Sections 3, 4 and 10 of the Agreement, and shall be paid to the Participant in cash, on the first payroll date following when the Participant’s related RSUs vest and are issued as Shares to the Participant or settled in cash, or as soon as practical thereafter.

8.Tax Withholdings and Payments.

a.The Company or any Subsidiary or Affiliate is authorized to withhold from any payment to be made to the Participant under this Agreement with respect to the RSUs, amounts of income tax withholding and other taxes due in connection with compensation or any other transaction under the Program, including the receipt of Shares under Section 6. The Participant shall hold the Company and its Subsidiaries and Affiliates harmless for any damages caused by his or her failure to so comply and for any other damages caused by his or her actions or inactions.

b.The Participant will pay withholding taxes attributable to the receipt of Shares in cash, by having Shares withheld by the Company from any Shares that would otherwise be received by the Participant under the Agreement (in which case, the number of Shares so withheld shall have an aggregate Fair Market Value at the time of such withholding sufficient to satisfy the applicable withholding taxes), or by any other method approved by the Committee. If the Participant does not satisfy the withholding obligation by cash payment within a reasonable time established by the Committee, the Participant’s withholding obligation shall be satisfied by the Company’s withholding of Shares from the vested RSUs.

c.The Company shall deduct from the dividend equivalents paid to the Participant pursuant to Section 7 the Participant’s withholding obligation arising from such payment.

9.Change in Control.

The RSUs are subject to the Change of Control provisions as set forth in detail in the Plan.

10.Forfeiture of RSUs.

a.Subject to the next following sentence, the Participant’s unvested RSUs shall be forfeited to the Company upon the Participant’s termination of Continuous Service for any reason other than (a) the Participant’s death or Disability that occurs prior to the date the RSUs vest as provided in Section 3 above, (b) the Participant’s termination of Continuous Service by the Company or any Subsidiary or Affiliate without Cause or the Participant’s voluntary termination due to the existence of Good Reason, in either case during the two-year period beginning on the date of a Change in Control, as provided in Section 9 above; or (c) in the case of the Chief Executive Officer and/or Tier 1 Participants, in the situation of the Participant’s termination of Continuous Service by the Company without Cause as outlined in the Program.

    - 3 -    

b.This Section 10 shall be subject to the Company’s Bonus, Restricted Stock Unit, Performance Stock Unit and Bonus Cash Deferral Retirement Policy (the “Retirement Policy”) and any subsequent amendments, as well as any other Company plan or written employment, severance or similar agreement that has been or may be executed by the Participant and the Company or its Subsidiary or Affiliate, and the provisions in such Retirement Policy or agreement concerning the vesting of RSUs in connection with the Participant’s termination of Continuous Service shall supersede any inconsistent or contrary provision in this Agreement.

c.The Participant agrees that the Company or its Subsidiary or Affiliate may deduct from any amounts the Company or its Subsidiary or Affiliate owes the Participant from time to time (such as wages or other compensation, deferred compensation credits, vacation pay, any severance or other payments owed following a termination of employment, as well as any other amounts owed to the Participant by the Company or its Subsidiary or Affiliate) to the extent of any amounts the Participant owes the Company or its Subsidiary or Affiliate under this Section 10. The provisions of this section and any amounts repayable by the Participant hereunder are intended to be in addition to any rights to repayment the Company or its Subsidiary or Affiliate may have under applicable law.

d.This Section 10 does not constitute the Company’s exclusive remedy for the Participant’s violation of any post-employment obligations owed to the Company, including but not limited to any obligations of confidentiality, or restrictive covenants that may exist in the Participant’s employment agreement.

e.Reasonableness. The Participant acknowledges that the Participant’s obligations under this Section 10 are reasonable in the context of the nature of the Company’s business, its strategic and cumulative investments in longstanding client relationships, and the competitive injuries likely to be sustained by the Company if the Participant were to violate such obligations. The Participant further acknowledges that this Agreement is made in consideration of, and is adequately supported by the agreement of the Company to perform its obligations under this Agreement and by other consideration, which the Participant acknowledges constitutes good, valuable and sufficient consideration.

11.Miscellaneous.

a.The Company or any Subsidiary or Affiliate shall have no obligation to continue the employment relationship or any other relationship as a result of an Award under the Program and/or the Agreement. The Participant acknowledges and agrees that: (i) the Program is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time;  (ii) the grant of RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of RSUs, or benefits in lieu of RSUs, even if RSUs have been granted repeatedly in the past; (iii) all decisions with respect to future RSU grants, if any, will be at the sole discretion of the Company; (iv) participation in the Program is voluntary; (v) the RSUs are not a part of normal or expected compensation or salary for any purposes; (vi) the future value of the underlying shares is unknown and cannot be predicted with certainty; and (vii) in consideration of the grant of RSUs, no claim or entitlement to compensation or damages shall arise from termination of the RSUs or diminution in value of the RSUs or Shares received upon vesting.

    - 4 -    

b.The Company may amend, alter or discontinue the Agreement, without the consent of the Participant so long as such amendment, alteration or discontinuance would not impair any of the rights or obligations under any Award theretofore granted to the Participant under the Program. The Committee may amend the Agreement in such manner as it deems necessary to permit the granting of Awards meeting the requirements of the Code or other applicable laws.

c.The parties agree that the Agreement shall be governed by and interpreted and construed in accordance with the laws of the United States and, in particular, those of the State of Illinois without regard to its conflict of law principles, as Illinois is the situs of the principal corporate office of the Company. Furthermore, to the extent not prohibited under applicable law, and unless the Company affirmatively elects in writing to allow the proceeding to be brought (or itself brings such a proceeding) in a different venue, the parties agree that any suit, action or proceeding with respect to the Program, the RSUs or the Agreement shall be brought in the state courts in Chicago, Illinois or in the U.S. District Court for the Northern District of Illinois. The parties hereby accept the exclusive jurisdiction of those courts for the purpose of any such suit, action or proceeding. Venue for any such action, in addition to any other venue required or otherwise mandated by statute, will be in Chicago, Illinois. Each party further agrees to waive any applicable right to a jury trial, and expressly elects to have the matter heard as a bench trial.

4.    Change in Control. The PSUs are subject to the Change of Control provisions as set forth in detail in the Plan.

    - 3 -    

    6.    Effect of Vesting.

(a)    If, and at the time, the Participant’s PSUs vest under the terms of Section 3 or Section 4, such Participant shall receive as full consideration for the PSUs a number of Shares equal to the number of PSUs which vested on such date.

(b)    The PSUs granted to the Participant shall be maintained in a bookkeeping account with the custodian appointed by the Committee from time to time (the “Custodian”) for such Participant if and until the PSUs are converted into Shares pursuant to this Section 6, at which time the Shares shall be issued to the Participant in accordance with Section 9 below.

7.    Forfeiture of PSUs. Subject to the next following sentence, the Participant’s PSUs shall be forfeited to the Company upon the Participant’s termination of Continuous Service with the Company and its Subsidiaries and Affiliates (a) for any reason other than the Participant’s death or Disability that occurs prior to the date the PSUs vest as provided in Section 3 above or (b) for any reason other than the Participant’s termination by the Company without Cause or the Participant’s voluntary termination due to the existence of Good Reason, in either case during the two-year period beginning on the date of a Change in Control, as provided in Section 4 above. The foregoing provisions of this Section 7 shall be subject to the provisions of the Company’s Bonus, Restricted Stock Unit, and Performance Stock Unit Retirement Policy (the “Retirement Policy”), and any other Company plan or written employment, severance or similar agreement that has been or may be executed by the Participant and the Company, and the provisions in such Retirement Policy or agreement concerning the vesting of the PSUs in connection with the Participant’s termination of Continuous Service shall supersede any inconsistent or contrary provision of this Section 7.

In any event, Shares due the Participant shall be delivered as described above no later than March 15 of the year following the calendar year in which such PSUs vest.

10.    Dividend Equivalents. The Company shall credit the Participant’s PSU account with an amount equal to the dividends, if any, that would be paid with respect to the unvested PSUs as if the PSUs were actual Shares to a shareholder as of the Record date. Such amount shall be credited to the Participant’s PSU account at the same time dividends are paid with respect to the Shares, shall be subject to the vesting and forfeiture provisions set forth in Sections 3, 4 and 7 of the Agreement, and shall be paid to the Participant in cash, on the first payroll date following the date the Participant’s related PSUs vest and are issued as Shares to the Participant.

    11.    Tax Withholdings and Payments.

(a)The Company or any Subsidiary or Affiliate is authorized to withhold from any payment to be made to the Participant, amounts of income tax

    - 4 -    

withholding and other taxes due in connection with compensation or any other transaction under the Program, including the receipt of Shares under Section 6. The Participant shall hold the Company harmless for any damages caused by his or her failure to so comply and for any other damages caused by his or her actions or inactions.

(b)The Participant may pay withholding taxes attributable to the receipt of Shares in cash, by having Shares withheld by the Company from any Shares that would otherwise be received by the Participant under the Agreement (in which case, the number of Shares so withheld shall have an aggregate Fair Market Value at the time of such withholding sufficient to satisfy the applicable withholding taxes), or by any other method approved by the Committee. If the Participant does not satisfy the withholding obligation by cash payment within a reasonable time established by the Committee, the Participant’s withholding obligation shall be satisfied by the Company’s withholding of Shares from the vested PSUs.

(c)The Company shall deduct from the dividend equivalents paid to the Participant pursuant to Section 10 the Participant’s withholding obligation arising from such payment.

12.    Miscellaneous.

(a)    The granting of an Award under the Program and the Agreement shall impose no obligation on the Company or any Subsidiary or Affiliate to continue the employment relationship or any other relationship between it and the Participant and shall not lessen or affect the Company’s, Subsidiary’s or Affiliate’s right to terminate its relationship with the Participant. The Participant shall have no claim to be granted any further or other Award under the Program, and there is no obligation for uniformity of treatment of the Participants. The Participant acknowledges and agrees that: (i) the Program is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time;  (ii) the grant of PSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of PSUs, or benefits in lieu of PSUs, even if PSUs have been granted repeatedly in the past; (iii) all decisions with respect to future PSU grants, if any, will be at the sole discretion of the Company; (iv) participation in the Program is voluntary; (v) the PSUs are not a part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments; (vi) the future value of the underlying shares is unknown and cannot be predicted with certainty; and (vii) in consideration of the grant of PSUs, no claim or entitlement to compensation or damages shall arise from termination of the PSUs or diminution in value of the PSUs or Shares received upon vesting including (without limitation) any claim or entitlement resulting from termination of the Participant’s active employment by the Company or a Subsidiary or Affiliate (for any reason whatsoever and whether or not in breach of local labor laws) and the Participant hereby releases the Company and its Subsidiaries and Affiliates from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by signing this Agreement, the Participant shall be deemed irrevocably to have waived the Participant’s entitlement to pursue such claim.

    - 5 -    

(b)    The Agreement shall, subject to the terms hereof, terminate upon the forfeiture and/or vesting of all PSUs and dividend equivalents granted to the Participant hereunder, unless otherwise agreed upon by the parties hereto.

(c)    The Agreement may be amended by the written agreement of the Company and the Participant. Notwithstanding the foregoing, (i) the Company may amend, alter or discontinue the Agreement, without the consent of the Participant so long as such amendment, alteration or discontinuance would not impair any of the rights or obligations under any Award theretofore granted to the Participant under the Program; and (ii) the Committee may amend the Agreement in such manner as it deems necessary to permit the granting of Awards meeting the requirements of the Code or other applicable laws.

(d)    The parties agree that the Agreement shall be governed by and interpreted and construed in accordance with the laws of the United States and, in particular, those of the State of Illinois without regard to its conflict of law principles, as Illinois is the situs of the principal corporate office of the Company. Furthermore, to the extent not prohibited under applicable law, and unless the Company affirmatively elects in writing to allow the proceeding to be brought (or itself brings such a proceeding) in a different venue, the parties agree that any suit, action or proceeding with respect to the Program, the PSUs or the Agreement shall be brought in the state courts in Chicago, Illinois or in the U.S. District Court for the Northern District of Illinois.

NOW, THEREFORE, in consideration of the agreements of the Participant herein provided and pursuant to the Program, the parties agree as follows:

1.Definitions. All capitalized terms used herein, unless specifically defined herein, shall have the same meanings as established in the Program.

2.Participation. Pursuant to the Program and contingent upon the execution of the Agreement, the Company hereby grants to the Participant [XXX] RSUs subject to the terms and conditions herein.

3.Vesting of RSUs. All RSUs granted under the Agreement shall vest on the date the Participant ceases to be a Director of the Company.

4.Effect of Vesting.

a.When the Participant’s RSUs vest under the terms of Section 3, such Participant shall receive as full consideration for the RSUs a number of shares of common stock with a par value $0.01 per Share, of the Company (“Shares”) equal to the number of RSUs which vested on such date.

b.The RSUs granted to the Participant shall be maintained in a bookkeeping account with the custodian appointed by the Human Resources and Compensation Committee of the Board (the “Committee”) from time to time (the “Custodian”) for such Participant until the RSUs are converted into Shares pursuant to this Section 4, at which time the Shares shall be issued to the Participant in accordance with Section 5 below.

5.Delivery of Shares to the Participant. As soon as practicable after the RSUs vest and are converted into Shares, and subject to the terms of this Agreement, the Custodian shall, without transfer or issue tax or other incidental expense to the Participant, deliver to the Participant by first-class insured mail addressed to the Participant at the address shown on page 1 or the last address of record on file with the Custodian, (i) a statement from the Custodian referencing the number of Shares held in the Participant’s name in book entry account, or (ii) at the Participant’s request, certificate(s) for the number of Shares as to which the Shares vested.

7.Dividend Equivalents. The Company shall credit the Participant’s RSU account with an amount equal to the dividends, if any, that would be paid with respect to the unvested RSUs as if the RSUs were actual Shares to a shareholder as of the record date. Such amount shall be credited to the Participant’s RSU account at the same time dividends are paid with respect to the Shares, shall be subject to the vesting provisions set forth in Section 3 of the Agreement, and shall be paid to the Participant in cash, as soon as practical following when the Participant’s

2

related RSUs vest and are issued as Shares to the Participant (but in any event no later than March 15 of the year following the calendar year in which such RSUs vest) .

8.Miscellaneous.

a.The Agreement shall, subject to the terms hereof, terminate upon the vesting of all RSUs and dividend equivalents granted to the Participant hereunder, unless otherwise agreed upon by the parties hereto.

b.The Agreement may be amended by the written agreement of the Company and the Participant.

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, 2022.

Revenue Recognition

See Note 3, Revenue.

Cost of Services

Cost of services consists of third-party contractor costs related to the delivery of various services in the Company's On-Demand Talent and Heidrick Consulting operating segments.

Research and Development

Research and development (“R&D”) expense consists of payroll, employee benefits, stock-based compensation, other employee expenses and third-party professional fees associated with the development of new technologies to enhance existing products and services and to expand the range of the Company's offerings. The benefits from the Company's R&D efforts are intended to be utilized to develop and enhance new and existing services and products across the Company's current offerings in Executive Search, Heidrick Consulting and On-Demand Talent, and for products and services in new segments that the Company may embark upon in the future from time to time.

Marketable Securities

The Company’s marketable securities consist of available-for-sale debt securities with original maturities exceeding three months.

Restricted Cash

The following table provides a reconciliation of the cash and cash equivalents between the Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Cash Flows as of June 30, 2023 and 2022, and December 31, 2022 and 2021:

Total cash, cash equivalents and restricted cash	$	217,817	$	336,650	$	355,489	$	545,259

Earnings per Common Share

Basic earnings per common share are computed by dividing net income by weighted average common shares outstanding for the period. 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:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Net income	$	8,982	$	24,149	$	24,568	$	42,616

Diluted earnings per share	$	0.44	$	1.19	$	1.19	$	2.08

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating Lease Right-of-Use Assets, Operating Lease Liabilities - Current and Operating Lease Liabilities - Non-Current in the Company's Condensed Consolidated Balance Sheets. The Company does not have any leases that meet the finance lease criteria.

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made in advance and any accrued rent expense balances. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components. For office leases, the Company accounts for the lease and non-lease components as a single lease component. For equipment leases, such as vehicles and office equipment, the Company accounts for the lease and non-lease components separately.

Goodwill

Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. These circumstances include a significant change in business climate, attrition of key personnel, changes in financial condition or results of operations, prolonged decline in the Company’s stock price and market capitalization, competition, and other factors.

The goodwill impairment test compares the fair value of a reporting unit to its carrying amount, including goodwill. The Company operates five reporting units: Americas, Europe (which includes Africa), Asia Pacific (which includes the Middle East), On-Demand Talent and Heidrick Consulting. The fair value of each of the Company’s reporting units is determined using a discounted cash flow methodology. An impairment charge is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit.

On October 31, 2022, the Company conducted its annual goodwill impairment evaluation, which indicated that the carrying value of the Heidrick Consulting reporting unit was less than its fair value. During the three months ended June 30, 2023, the Company acquired businessfourzero and recorded approximately $7.1 million of goodwill in the Heidrick Consulting reporting unit. Due to the inclusion of goodwill in a reporting unit with a pre-existing fair value shortfall, the Company evaluated the recent and anticipated future financial performance of the Heidrick Consulting reporting unit and determined that it was more likely than not that the fair value of the reporting unit was less than its carrying value. As a result, the Company identified a triggering event and performed an interim goodwill impairment evaluation during the three months ended June 30, 2023.

During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. 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; (4) macroeconomic conditions and (5) other factors.

Based on the results of the impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million to write-off all of the associated goodwill. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2023, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2023. The impairment was non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations; nor did it impact the debt covenants under the Company's credit agreement.

Recently Issued Financial Accounting Standards

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance is intended to provide temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is effective March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2024. The Company is currently evaluating the impact of this accounting guidance. The new guidance is not expected to have a material effect on the Company's financial statements.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

Executive Search

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Generally, each executive search contract contains one performance obligation which is the process of identifying potentially qualified candidates for a specific client position. In most contracts, the transaction price includes both fixed and variable consideration. Fixed compensation is comprised of a retainer, equal to approximately one-third of the estimated first year compensation for the position to be filled, and indirect expenses, equal to a specified percentage of the retainer, as defined in the contract. The Company generally bills clients for the 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. If actual compensation of a placed candidate exceeds the original compensation estimate, the Company is often authorized to bill the client for one-third of the excess compensation. The Company refers to this additional billing as uptick revenue. In most contracts, variable consideration is comprised of uptick revenue and direct expenses. The Company bills its clients for uptick revenue upon completion of the executive search, and direct expenses are billed as incurred.

The Company estimates uptick revenue at contract inception, based on a portfolio approach, utilizing the expected value method based on a historical analysis of uptick revenue realized in the Company’s geographic regions and industry practices, and initially records a contract’s uptick revenue in an amount that is probable not to result in a significant reversal of cumulative revenue recognized when the actual amount of uptick revenue for the contract is known. Differences between the estimated and actual amounts of variable consideration are recorded when known. The Company does not estimate revenue for direct expenses as it is not materially different than recognizing revenue as direct expenses are incurred.

Revenue from executive search engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance.  Revenue from executive search engagements is recognized over the expected average period of performance, in proportion to the estimated personnel time incurred to fulfill the obligations under the executive search contract. Revenue is generally recognized over a period of approximately six months.

The Company's executive search contracts contain a replacement guarantee which provides for an additional search to be completed, free of charge except for expense reimbursements, should the candidate presented by the Company be hired by the client and subsequently terminated by the client for performance reasons within a specified period of time. The replacement guarantee is an assurance warranty, which is not a performance obligation under the terms of the executive search contract, as the Company does not provide any services under the terms of the guarantee that transfer benefits to the client in excess of assuring that the identified candidate complies with the agreed-upon specifications. The Company accounts for the replacement guarantee under the relevant warranty guidance in Accounting Standards Codification 460 - Guarantees.

On-Demand Talent

The Company enters into contracts with clients that outline the general terms and conditions of the assignment to provide on-demand consultants for various types of consulting projects, which consultants may be independent contractors or temporary employees. The consideration the Company expects to receive under each contract is dependent on the time-based fees specified in the contract. Revenue from on-demand engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. The Company has applied the practical expedient to recognize revenue for these services in the amount to which the Company has a right to invoice the client, as this amount corresponds directly with the value provided to the client for the performance completed to date. For transactions where a third-party contractor is involved in providing the services to the client, the Company reports the revenue and the related direct costs on a gross basis as it has determined that it is the principal in the transaction. The Company is primarily responsible for fulfilling the promise to provide consulting services to its clients and the Company has discretion in establishing the prices charged to clients for the consulting services and is able to contractually obligate the independent service provider to deliver services and deliverables that the Company has agreed to provide to its clients.

Heidrick Consulting

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Heidrick Consulting enters into contracts with clients that outline the general terms and conditions of the assignment to provide succession planning, executive assessment, top team and board effectiveness and culture shaping programs. The consideration the Company expects to receive under each contract is generally fixed. Most of the Company's consulting contracts contain one performance obligation, which is the overall process of providing the consulting service requested by the client. The majority of the Company's consulting revenue is recognized over time utilizing both input and output methods. Contracts that contain coaching sessions, training sessions or the completion of assessments are recognized using the output method as each session or assessment is delivered to the client. Contracts that contain general consulting work are recognized using the input method utilizing a measure of progress that is based on time incurred on the project.

The Company enters into enterprise agreements with clients to provide a license for online access, via the Company's Culture Connect platform, to training and other proprietary material related to the Company's culture shaping programs. The consideration the Company expects to receive under the terms of an enterprise agreement is comprised of a single fixed fee. The enterprise agreements contain multiple performance obligations, the delivery of materials via Culture Connect and material rights related to options to renew enterprise agreements at a significant discount. The Company allocates the transaction price to the performance obligations in the contract on a stand-alone selling price basis. The stand-alone selling price for the initial term of the enterprise agreement is outlined in the contract and is equal to the price paid by the client for the agreement over the initial term of the contract. The stand-alone selling price for the options to renew, or material right, are not directly observable and must be estimated. This estimate is required to reflect the discount the client would obtain when exercising the option to renew, adjusted for the likelihood that the option will be exercised. The Company estimates the likelihood of renewal using a historical analysis of client renewals. Access to Culture Connect represents a right to access the Company’s intellectual property that the client simultaneously receives and consumes as the Company performs under the agreement, and therefore the Company recognizes revenue over time. Given the continuous nature of this commitment, the Company utilizes straight-line ratable revenue recognition over the estimated subscription period as the Company's clients will receive and consume the benefits from Culture Connect equally throughout the contract period. Revenue related to client renewals of enterprise agreements is recognized over the term of the renewal, which is generally twelve months. Enterprise agreements do not comprise a significant portion of the Company's revenue.

Contract Balances

Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities are classified as current due to the nature of the Company's contracts, which are completed within one year. Contract assets are included within Other current assets on the Condensed Consolidated Balance Sheets.

Unbilled receivables: Unbilled receivables represents contract assets from revenue recognized over time in excess of the amount billed to the client and the amount billed to the client is solely dependent upon the passage of time. This amount includes revenue recognized in excess of billed Executive Search retainers, Heidrick Consulting fees, and On-Demand Talent fees.

Contract assets: Contract assets represent revenue recognized over time in excess of the amount billed to the client, and the amount billed to the client is not solely subject to the passage of time. This amount primarily includes revenue recognized for upticks and contingent placement fees in executive search contracts.

Deferred revenue: Contract liabilities consist of deferred revenue, which is equal to billings in excess of revenue recognized.

The following table outlines the changes in the contract asset and liability balances from December 31, 2022 to June 30, 2023:

	June 30, 2023		December 31, 2022		Change

Total contract assets	36,581		35,288		1,293
Contract liabilities
Deferred revenue	$	44,102	$	43,057	$	1,045

During the six months ended June 30, 2023, the Company recognized revenue of $34.2 million that was included in the contract liabilities balance at the beginning of the period. The amount of revenue recognized during the six months ended June 30, 2023 from performance obligations partially satisfied in previous periods as a result of changes in the estimates of variable consideration was $14.4 million.

Each of the Company's contracts has an expected duration of one year or less. Accordingly, the Company has elected to utilize the available practical expedient related to the disclosure of the transaction price allocated to the remaining performance obligations under its contracts. The Company has also elected the available practical expedients related to adjusting for the effects of a significant financing component and the capitalization of contract acquisition costs. The Company charges and collects from its clients sales tax and value added taxes as required by certain jurisdictions. The Company has made an accounting policy election to exclude these items from the transaction price in its contracts.

Credit Loss [Abstract]

Credit Losses

Credit Losses

The Company is exposed to credit losses primarily through the provision of its executive search, consulting, and on-demand talent services. The Company’s expected credit loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of clients' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of amount of accounts receivable that may not be collected is primarily based on historical loss-rate experience. When required, the Company adjusts the loss-rate methodology to account for current conditions and reasonable and supportable expectations of future economic and market conditions. The Company generally assesses future economic conditions for a period of sixty to ninety days, which corresponds with the contractual life of its accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for clients that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of clients' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

The activity in the allowance for credit losses on the Company's trade receivables is as follows:

Balance at December 31, 2022	$	6,643
Provision for credit losses	3,703
Write-offs	(3,373)
Foreign currency translation	6
Balance at June 30, 2023	$	6,979

There were no investments with unrealized losses at June 30, 2023. At December 31, 2022, the fair value and unrealized losses on available for sale debt securities, aggregated by investment category and the length of time the security has been in an unrealized loss position, are as follows:

	Less Than 12 Months				Balance Sheet Classification
Balance at December 31, 2022	Fair Value		Unrealized Loss		Cash and Cash Equivalents		Marketable Securities
U.S. Treasury securities	$	194,056	$	56	$	11,918	$	182,138

The unrealized loss on one investment in U.S. Treasury securities at December 31, 2022 was caused by fluctuations in market interest rates. The contractual cash flows of these investments are guaranteed by an agency of the U.S. government. Accordingly, it is expected that the investments would not be settled at a price less than the amortized cost basis. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before the recovery of the amortized cost basis.

Leases [Abstract]

Leases

Leases

The Company's lease portfolio is comprised of operating leases for office space and equipment. The majority of the Company's leases include both lease and non-lease components, which the Company accounts for differently depending on the underlying class of asset. Certain of the Company's leases include one or more options to renew or terminate the lease at the Company's discretion. Generally, the renewal and termination options are not included in the right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates the renewal and termination options and when they are reasonably certain of exercise, includes the renewal or termination option in the lease term.

As most of the Company's leases do not provide an implicit interest rate, the Company utilizes an incremental borrowing rate based on the information available at the commencement date of the lease in determining the present value of lease payments. The Company has a centrally managed treasury function and, therefore, a portfolio approach is applied in determining the incremental borrowing rate. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a fully collateralized basis over a similar term in an amount equal to the total lease payments in a similar economic environment.

Office leases have remaining lease terms that range from less than one year to 10.1 years, some of which also include options to extend or terminate the lease. Most office leases contain both fixed and variable lease payments. Variable lease costs consist primarily of rent escalations based on an established index or rate and taxes, insurance, and common area or other maintenance costs, which are paid based on actual costs incurred by the lessor. The Company has elected to utilize the available practical expedient to not separate lease and non-lease components for office leases.

Equipment leases, which are comprised of vehicle and office equipment leases, have remaining terms that range from less than one year to 5.0 years, some of which also include options to extend or terminate the lease. The Company's equipment leases do not contain variable lease payments. The Company separates the lease and non-lease components for its equipment leases. Equipment leases do not comprise a significant portion of the Company's lease portfolio.

Lease cost components included within General and administrative expenses in the Condensed Consolidated Statements of Comprehensive Income were as follows:

Investments, Assets Designated for Retirement and Pension Plans and Associated Liabilities

The Company has a U.S. non-qualified deferred compensation plan that consists primarily of U.S. marketable securities and mutual funds. The aggregate cost basis for these investments was $35.5 million and $29.1 million as of June 30, 2023 and December 31, 2022, respectively.

The Company also maintains a pension plan for certain current and former employees in Germany. The pensions are individually fixed Euro amounts that vary depending on the function and the eligible years of service of the employee. The Company’s investment strategy is to support its pension obligations through reinsurance contracts. The BaFin—German Federal Financial Supervisory Authority—supervises the insurance companies and the reinsurance contracts. The BaFin requires each reinsurance contract to guarantee a fixed minimum return. The Company’s pension benefits are fully reinsured by group insurance contracts with ERGO Lebensversicherung AG, and the group insurance contracts are measured in accordance with BaFin guidelines (including mortality tables and discount rates) which are considered Level 2 inputs.

The following tables provide a summary of the fair value measurements for each major category of investments, assets designated for retirement and pension plans and associated liabilities measured at fair value:

Contingent Consideration and Compensation

The former owners of the Company's acquired businesses are eligible to receive contingent consideration or additional cash compensation based on the attainment of certain operating metrics or performance criteria in the periods subsequent to acquisition. Contingent consideration and compensation are valued using significant inputs that are not observable in the market, which are defined as Level 3 inputs pursuant to fair value measurement accounting. The Company determines the fair value of contingent consideration and compensation using discounted cash flow models.

The following table provides a reconciliation of the beginning and ending balance of Level 3 liabilities for the six months ended June 30, 2023:

Contingent compensation accruals of $7.3 million and $1.5 million are recorded within current Accrued salaries and benefits as of June 30, 2023 and December 31, 2022, respectively, and contingent compensation accruals of $7.2 million and $6.7 million are recorded within non-current Accrued salaries and benefits as of June 30, 2023 and December 31, 2022, respectively.

Goodwill

Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. During the three months ended June 30, 2023, an interim goodwill impairment evaluation was conducted to determine the fair value of the Company's goodwill. Goodwill is valued using significant inputs that are not observable in the market which are defined as Level 3 inputs pursuant to fair value measurement accounting. The Company determines the fair value of goodwill using discounted cash flow models.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions On February 1, 2023, the Company acquired Atreus Group GmbH ("Atreus"), a leading provider of executive interim management in Germany. The Company paid $33.4 million in the first quarter of 2023, with a subsequent estimated payment of between $9.0 million and $13.0 million to be paid in 2023 upon the completion of Atreus' statutory audit for the year ended December 31, 2022, for all of the outstanding equity of Atreus. The former owners of Atreus are eligible to receive additional cash consideration, which the Company estimated on the acquisition date to be between $30.0 million and $40.0 million, based on the achievement of certain revenue and operating income milestones for the period from the acquisition date through 2025. When estimating the present value of future cash consideration, the Company accrued an estimated $32.0 million as of the acquisition date for the earnout liability. The Company recorded an estimated $11.3 million for customer relationships, $6.9 million for software, $2.5 million for a trade name and $59.5 million of goodwill. Goodwill is primarily related to the acquired workforce and strategic fit and is not deductible for tax purposes. The consideration transferred was allocated on a preliminary basis to the assets acquired and liabilities assumed on their estimated fair values at the date of acquisition. The measurement period for purchase price allocation ends when information on the facts and circumstances becomes available, not to exceed twelve months, and the Company expects to finalize its measurements for the acquisition during the third quarter of 2023 pending the completion of the statutory audit. As of June 30, 2023, the allocations remain preliminary with regard to customer relationships, software, trade name, goodwill and earnout liability.On April 1, 2023, the Company acquired businessfourzero, a next generation consultancy specializing in developing and implementing purpose-driven change. In connection with the acquisition, the Company paid $9.5 million in the second quarter of 2023 with a subsequent estimated working capital settlement of approximately $2.0 million to be paid in the third quarter of 2023. The former owners of businessfourzero are eligible to receive additional cash consideration, which the Company estimated on the acquisition date to be between $4.0 million and $8.0 million, to be paid in 2026 based on the achievement of certain revenue and operating income metrics for the period from the acquisition date through 2025. When estimating the present value of future cash consideration, the Company accrued an estimated $4.3 million as of the acquisition date for the earnout liability. The Company recorded an estimated $3.5 million for customer relationships, $0.5 million for a trade name, and $7.1 million of goodwill. The consideration transferred was allocated on a preliminary basis to the assets acquired and liabilities assumed on their estimated fair values at the date of acquisition. The measurement period for purchase price allocation ends when information on the facts and circumstances becomes available, not to exceed twelve months, and the Company expects to finalize its measurements for the acquisition during the third quarter of 2023. As of June 30, 2023, the allocations remain preliminary with regard to customer relationships, trade name, goodwill and earnout liability.

In February 2023, the Company acquired Atreus and recorded an estimated $59.5 million of goodwill related to the acquisition in the On-Demand Talent operating segment. In April 2023, the Company acquired businessfourzero and recorded an estimated $7.1 million of goodwill related to the acquisition in the Heidrick Consulting operating segment.

On October 31, 2022, the Company conducted its annual goodwill impairment evaluation, which indicated that the carrying value of the Heidrick Consulting reporting unit was less than its fair value. During the three months ended June 30, 2023, the Company acquired businessfourzero and recorded approximately $7.1 million of goodwill in the Heidrick Consulting reporting unit. Due to the inclusion of goodwill in a reporting unit with a pre-existing fair value shortfall, the Company evaluated the recent and anticipated future financial performance of the Heidrick Consulting reporting unit and determined that it was more likely than not that the fair value of the reporting unit was less than its carrying value. As a result, the Company identified a triggering event and performed an interim goodwill impairment evaluation during the three months ended June 30, 2023.

During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. 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; (4) macroeconomic conditions and (5) other factors.

Based on the results of the impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million to write-off all of the associated goodwill. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2023, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2023.. The impairment was non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations, nor did it impact the debt covenants under the Company's credit agreement.

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation and Common Stock

Stock-Based Compensation and Common Stock

On May 25, 2023, the stockholders of the Company approved an amendment to the Company's Third Amended and Restated 2012 Heidrick & Struggles GlobalShare Program (as so amended, the "Fourth A&R Program") to increase the number of shares of common stock reserved for issuance under the 2012 program by 1,060,000 shares. The Fourth A&R Program provides for grants of stock options, stock appreciation rights, restricted stock units, performance stock units, and other stock-based compensation awards that are valued based upon the grant date fair value of the awards. These awards may be granted to directors, selected employees and independent contractors.

As of June 30, 2023, 4,158,627 awards have been issued under the Fourth A&R Program, including 771,055 forfeited awards, and 1,022,428 shares remain available for future awards. The Fourth A&R Program provides that no awards can be granted after May 25, 2033.

The Company measures its stock-based compensation costs based on the grant date fair value of the awards and recognizes these costs 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,
	2023		2022		2023		2022
Salaries and benefits (1)	$	806	$	1,274	$	3,403	$	4,178
General and administrative expenses	810		810		810		810
Income tax benefit related to stock-based compensation included in net income	445		568		1,160		1,358

(1) Includes $0.7 million and $2.1 million of income related to cash-settled restricted stock units for the three months ended June 30, 2023 and 2022, respectively and $0.1 million of expense and $2.8 million of income related to cash-settled restricted stock units for the six months ended June 30, 2023 and 2022, respectively.

Restricted Stock Units

Restricted stock units are subject to ratable vesting over a three-year or four-year period dependent upon the terms of the individual grant. Compensation expense related to service-based restricted stock units is recognized on a straight-line basis over the vesting period.

Non-employee directors of the Board of Directors may elect to receive restricted stock units or shares of common stock annually pursuant to the Fourth A&R Program as part of their annual compensation. Based on their respective elections, the Company issued 16,134 and 11,850 restricted stock units for services provided by the non-employee directors during the three months ended June 30, 2023 and 2022, respectively. Restricted stock units issued to non-employee directors remain unvested until the non-employee director retires from the Board of Directors.

Restricted stock unit activity for the six months ended June 30, 2023 is as follows:

	Number of Restricted Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2022	728,285	$	31.97
Granted	268,741	26.90
Vested and converted to common stock	(171,420)	33.07
Forfeited	(12,423)	31.30
Outstanding on June 30, 2023	813,183	$	30.08

As of June 30, 2023, there was $10.8 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.6 years.

Performance Stock Units

The Company grants performance stock units to certain of its senior executives. The performance stock units are generally subject to cliff vesting at the end of a three-year period. The vesting will vary between 0% and 200% based on the attainment of certain performance and market conditions over the three-year vesting period. Half of the award is based on the achievement of operating margin thresholds and half of the award is based on the Company's total shareholder return, relative to a peer group. The fair value of the awards subject to total shareholder return metrics is 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 performance conditions and the resulting fair value of the award. The performance stock units are expensed on a straight-line basis over the three-year vesting period.

Performance stock unit activity for the six months ended June 30, 2023 is as follows:

	Number of Performance Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2022	260,452	$	40.02
Granted	103,916	34.14
Vested and converted to common stock	(124,743)	31.51
Forfeited	—	—
Outstanding on June 30, 2023	239,625	$	41.91

As of June 30, 2023, there was $5.6 million of pre-tax unrecognized compensation expense related to unvested performance stock units, which is expected to be recognized over a weighted average of 2.0 years.

Phantom Stock Units

Phantom stock units are grants of phantom stock with respect to shares of the Company's common stock that are settled in cash and are subject to various restrictions, including restrictions on transferability, vesting and forfeiture provisions. Shares of phantom stock that do not vest for any reason will be forfeited by the recipient and will revert to the Company.

Phantom stock units are subject to vesting over a period of four years, and such vesting is subject to certain other conditions, including continued service to the Company. As a result of the cash-settlement feature of the awards, the Company classifies the awards as liability awards, which are measured at fair value at each reporting date and the vested portion of the award is recognized as a liability to the extent that the service condition is deemed probable. The fair value of the phantom stock awards on the balance sheet date is determined using the closing share price of the Company's common stock on that date.

The Company recorded phantom stock-based compensation income of $0.7 million and $2.1 million during the three months ended June 30, 2023 and 2022, respectively and $0.1 million of expense and $2.8 million of income related to phantom stock units during the six months ended June 30, 2023 and 2022, respectively.

Phantom stock unit activity for the six months ended June 30, 2023 is as follows:

	Number of Phantom Stock Units
Outstanding on December 31, 2022	321,155
Granted	—
Vested	—
Forfeited	(9,775)
Outstanding on June 30, 2023	311,380

As of June 30, 2023, there was $1.4 million of pre-tax unrecognized compensation expense related to unvested phantom stock units, which is expected to be recognized over a weighted average of 2.6 years.

Common Stock

Non-employee directors of the Board of Directors may elect to receive restricted stock units or shares of common stock annually pursuant to the Fourth A&R Program as part of their annual compensation. Based on their respective elections, the Company issued 16,134 and 11,850 shares of common stock for services provided by the non-employee directors during the three months ended June 30, 2023 and 2022, respectively.

On February 11, 2008, the Company's Board of Directors authorized management to repurchase shares of the Company's common stock with an aggregate purchase price of up to $50 million (the "Repurchase Authorization"). From time to time and as business conditions warrant, the Company may purchase shares of its common stock on the open market or in negotiated or block trades. No time limit has been set for completion of this program. During the three months ended June 30, 2023, the Company purchased 36,000 shares of common stock for $0.9 million. There were no purchases of shares of common stock in 2022 and prior to the 2023 purchase, the most recent purchase of the Company's shares of common stock occurred during the year ended December 31, 2012. As of June 30, 2023, the Company has purchased 1,074,670 shares of its common stock

pursuant to the Repurchase Authorization for a total of $29.2 million and $20.8 million remains available for future purchases under the Repurchase Authorization.

Segment Information

Segment Information

The Company has five operating segments. The Executive Search business operates in the Americas, Europe (which includes Africa) and Asia Pacific (which includes the Middle East), and the Heidrick Consulting and On-Demand Talent businesses operate globally.

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 reflect its core operations.

Accounting Policies [Abstract]

Cost of Services

Cost of Services

Cost of services consists of third-party contractor costs related to the delivery of various services in the Company's On-Demand Talent and Heidrick Consulting operating segments.

Research and Development

Research and Development

Research and development (“R&D”) expense consists of payroll, employee benefits, stock-based compensation, other employee expenses and third-party professional fees associated with the development of new technologies to enhance existing products and services and to expand the range of the Company's offerings. The benefits from the Company's R&D efforts are intended to be utilized to develop and enhance new and existing services and products across the Company's current offerings in Executive Search, Heidrick Consulting and On-Demand Talent, and for products and services in new segments that the Company may embark upon in the future from time to time.

Marketable Securities

Marketable Securities

The Company’s marketable securities consist of available-for-sale debt securities with original maturities exceeding three months.

Restricted Cash

Restricted Cash

The following table provides a reconciliation of the cash and cash equivalents between the Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Cash Flows as of June 30, 2023 and 2022, and December 31, 2022 and 2021:

Earnings per Common Share

Earnings per Common Share

Basic earnings per common share are computed by dividing net income by weighted average common shares outstanding for the period. 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.

Leases

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating Lease Right-of-Use Assets, Operating Lease Liabilities - Current and Operating Lease Liabilities - Non-Current in the Company's Condensed Consolidated Balance Sheets. The Company does not have any leases that meet the finance lease criteria.

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made in advance and any accrued rent expense balances. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components. For office leases, the Company accounts for the lease and non-lease components as a single lease component. For equipment leases, such as vehicles and office equipment, the Company accounts for the lease and non-lease components separately.

Goodwill

Goodwill

Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is accounted for by the acquisition method of accounting. The Company performs assessments of the carrying value of goodwill at least annually and whenever events occur or circumstances indicate that a carrying amount of goodwill may not be recoverable. These circumstances include a significant change in business climate, attrition of key personnel, changes in financial condition or results of operations, prolonged decline in the Company’s stock price and market capitalization, competition, and other factors.

The goodwill impairment test compares the fair value of a reporting unit to its carrying amount, including goodwill. The Company operates five reporting units: Americas, Europe (which includes Africa), Asia Pacific (which includes the Middle East), On-Demand Talent and Heidrick Consulting. The fair value of each of the Company’s reporting units is determined using a discounted cash flow methodology. An impairment charge is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit.

On October 31, 2022, the Company conducted its annual goodwill impairment evaluation, which indicated that the carrying value of the Heidrick Consulting reporting unit was less than its fair value. During the three months ended June 30, 2023, the Company acquired businessfourzero and recorded approximately $7.1 million of goodwill in the Heidrick Consulting reporting unit. Due to the inclusion of goodwill in a reporting unit with a pre-existing fair value shortfall, the Company evaluated the recent and anticipated future financial performance of the Heidrick Consulting reporting unit and determined that it was more likely than not that the fair value of the reporting unit was less than its carrying value. As a result, the Company identified a triggering event and performed an interim goodwill impairment evaluation during the three months ended June 30, 2023.

During the impairment evaluation process, the Company used a discounted cash flow methodology to estimate the fair value of each of its reporting units. 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; (4) macroeconomic conditions and (5) other factors.

Based on the results of the impairment evaluation, the Company determined that the goodwill within the Heidrick Consulting reporting unit was impaired, which resulted in an impairment charge of $7.2 million to write-off all of the associated goodwill. The impairment charge is recorded within Impairment charges in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2023, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2023. The impairment was non-cash in nature and did not affect the Company's current liquidity, cash flows, borrowing capability or operations; nor did it impact the debt covenants under the Company's credit agreement.

The guidance is intended to provide temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is effective March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2024. The Company is currently evaluating the impact of this accounting guidance. The new guidance is not expected to have a material effect on the Company's financial statements.

Revenue Recognition

Executive Search

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Generally, each executive search contract contains one performance obligation which is the process of identifying potentially qualified candidates for a specific client position. In most contracts, the transaction price includes both fixed and variable consideration. Fixed compensation is comprised of a retainer, equal to approximately one-third of the estimated first year compensation for the position to be filled, and indirect expenses, equal to a specified percentage of the retainer, as defined in the contract. The Company generally bills clients for the 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. If actual compensation of a placed candidate exceeds the original compensation estimate, the Company is often authorized to bill the client for one-third of the excess compensation. The Company refers to this additional billing as uptick revenue. In most contracts, variable consideration is comprised of uptick revenue and direct expenses. The Company bills its clients for uptick revenue upon completion of the executive search, and direct expenses are billed as incurred.

The Company estimates uptick revenue at contract inception, based on a portfolio approach, utilizing the expected value method based on a historical analysis of uptick revenue realized in the Company’s geographic regions and industry practices, and initially records a contract’s uptick revenue in an amount that is probable not to result in a significant reversal of cumulative revenue recognized when the actual amount of uptick revenue for the contract is known. Differences between the estimated and actual amounts of variable consideration are recorded when known. The Company does not estimate revenue for direct expenses as it is not materially different than recognizing revenue as direct expenses are incurred.

Revenue from executive search engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance.  Revenue from executive search engagements is recognized over the expected average period of performance, in proportion to the estimated personnel time incurred to fulfill the obligations under the executive search contract. Revenue is generally recognized over a period of approximately six months.

The Company's executive search contracts contain a replacement guarantee which provides for an additional search to be completed, free of charge except for expense reimbursements, should the candidate presented by the Company be hired by the client and subsequently terminated by the client for performance reasons within a specified period of time. The replacement guarantee is an assurance warranty, which is not a performance obligation under the terms of the executive search contract, as the Company does not provide any services under the terms of the guarantee that transfer benefits to the client in excess of assuring that the identified candidate complies with the agreed-upon specifications. The Company accounts for the replacement guarantee under the relevant warranty guidance in Accounting Standards Codification 460 - Guarantees.

On-Demand Talent

The Company enters into contracts with clients that outline the general terms and conditions of the assignment to provide on-demand consultants for various types of consulting projects, which consultants may be independent contractors or temporary employees. The consideration the Company expects to receive under each contract is dependent on the time-based fees specified in the contract. Revenue from on-demand engagement performance obligations is recognized over time as clients simultaneously receive and consume the benefits provided by the Company's performance. The Company has applied the practical expedient to recognize revenue for these services in the amount to which the Company has a right to invoice the client, as this amount corresponds directly with the value provided to the client for the performance completed to date. For transactions where a third-party contractor is involved in providing the services to the client, the Company reports the revenue and the related direct costs on a gross basis as it has determined that it is the principal in the transaction. The Company is primarily responsible for fulfilling the promise to provide consulting services to its clients and the Company has discretion in establishing the prices charged to clients for the consulting services and is able to contractually obligate the independent service provider to deliver services and deliverables that the Company has agreed to provide to its clients.

Heidrick Consulting

Revenue is recognized as performance obligations are satisfied by transferring a good or service to a client. Heidrick Consulting enters into contracts with clients that outline the general terms and conditions of the assignment to provide succession planning, executive assessment, top team and board effectiveness and culture shaping programs. The consideration the Company expects to receive under each contract is generally fixed. Most of the Company's consulting contracts contain one performance obligation, which is the overall process of providing the consulting service requested by the client. The majority of the Company's consulting revenue is recognized over time utilizing both input and output methods. Contracts that contain coaching sessions, training sessions or the completion of assessments are recognized using the output method as each session or assessment is delivered to the client. Contracts that contain general consulting work are recognized using the input method utilizing a measure of progress that is based on time incurred on the project.

The Company enters into enterprise agreements with clients to provide a license for online access, via the Company's Culture Connect platform, to training and other proprietary material related to the Company's culture shaping programs. The consideration the Company expects to receive under the terms of an enterprise agreement is comprised of a single fixed fee. The enterprise agreements contain multiple performance obligations, the delivery of materials via Culture Connect and material rights related to options to renew enterprise agreements at a significant discount. The Company allocates the transaction price to the performance obligations in the contract on a stand-alone selling price basis. The stand-alone selling price for the initial term of the enterprise agreement is outlined in the contract and is equal to the price paid by the client for the agreement over the initial term of the contract. The stand-alone selling price for the options to renew, or material right, are not directly observable and must be estimated. This estimate is required to reflect the discount the client would obtain when exercising the option to renew, adjusted for the likelihood that the option will be exercised. The Company estimates the likelihood of renewal using a historical analysis of client renewals. Access to Culture Connect represents a right to access the Company’s intellectual property that the client simultaneously receives and consumes as the Company performs under the agreement, and therefore the Company recognizes revenue over time. Given the continuous nature of this commitment, the Company utilizes straight-line ratable revenue recognition over the estimated subscription period as the Company's clients will receive and consume the benefits from Culture Connect equally throughout the contract period. Revenue related to client renewals of enterprise agreements is recognized over the term of the renewal, which is generally twelve months. Enterprise agreements do not comprise a significant portion of the Company's revenue.

Contract Balances

Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities are classified as current due to the nature of the Company's contracts, which are completed within one year. Contract assets are included within Other current assets on the Condensed Consolidated Balance Sheets.

Unbilled receivables: Unbilled receivables represents contract assets from revenue recognized over time in excess of the amount billed to the client and the amount billed to the client is solely dependent upon the passage of time. This amount includes revenue recognized in excess of billed Executive Search retainers, Heidrick Consulting fees, and On-Demand Talent fees.

Contract assets: Contract assets represent revenue recognized over time in excess of the amount billed to the client, and the amount billed to the client is not solely subject to the passage of time. This amount primarily includes revenue recognized for upticks and contingent placement fees in executive search contracts.

Deferred revenue: Contract liabilities consist of deferred revenue, which is equal to billings in excess of revenue recognized.
