NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(All tables in thousands, except per share figures)

(Unaudited) 

1.    Basis of Presentation of Interim Financial Information

The accompanying unaudited Condensed Consolidated Financial Statements of Heidrick & Struggles International, Inc. and subsidiaries (the "Company") have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Significant items subject to estimates and assumptions include revenue recognition, income taxes, interim effective tax rate and 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, 2022 and December 31, 2021, the results of operations for the three and six months ended June 30, 2022 and 2021 and its cash flows for the six months ended June 30, 2022 and 2021 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, 2021, as filed with the SEC on February 28, 2022.

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, 2021.

Revenue Recognition

Earnings per Common Share

Basic earnings per common share is 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,
	2022		2021		2022		2021
Net income	$	24,149	$	20,765	$	42,616	$	35,597
Weighted average shares outstanding:
Basic	19,726		19,510		19,675		19,449
Effect of dilutive securities:
Restricted stock units	455		498		608		593
Performance stock units	133		107		202		155
Diluted	20,314		20,115		20,485		20,197
Basic earnings per share	$	1.22	$	1.06	$	2.17	$	1.83
Diluted earnings per share	$	1.19	$	1.03	$	2.08	$	1.76

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.

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, 2022. 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

The following table outlines the changes in the contract asset and liability balances from December 31, 2021 to June 30, 2022:

	June 30, 2022		December 31, 2021		Change
Contract assets
Unbilled receivables, net	$	19,592	$	17,947	$	1,645
Contract assets	21,639		18,995		2,644
Total contract assets	41,231		36,942		4,289
Contract liabilities
Deferred revenue	$	48,764	$	51,404	$	(2,640)

During the six months ended June 30, 2022, the Company recognized revenue of $42.3 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, 2022, from performance obligations partially satisfied in previous periods as a result of changes in the estimates of variable consideration was $12.7 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, 2021	$	5,666
Provision for credit losses	3,966
Write-offs	(2,876)
Foreign currency translation	(110)
Balance at June 30, 2022	$	6,646

The Company had zero available for sale debt securities in an unrealized loss position at June 30, 2022 and December 31, 2022.

5.    Property and Equipment, net

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

	June 30, 2022		December 31, 2021
Leasehold improvements	$	40,635	$	42,252
Office furniture, fixtures and equipment	13,748		14,933
Computer equipment and software	26,590		24,293
Property and equipment, gross	80,973		81,478
Accumulated depreciation	(53,679)		(54,393)
Property and equipment, net	$	27,294	$	27,085

Depreciation expense for the three months ended June 30, 2022 and 2021 was $1.8 million and $1.7 million, respectively. Depreciation expense for the six months ended June 30, 2022 and 2021 was $3.6 million and $3.5 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 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 11.0 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.

As part of the Company's 2020 Plan (as defined below), a lease component related to one of the Company's offices was abandoned and the useful life of the associated right-of-use asset was shortened to correspond with the cease-use date. As a result of the change in the useful life, approximately $3.5 million and $7.5 million of right-of-use asset amortization was accelerated and recorded in Restructuring charges in the Condensed Consolidated Statements of Comprehensive Income and Depreciation and amortization in the Condensed Consolidated Statements of Cash Flows during the three and six months ended June 30, 2021, respectively.

Equipment leases, which are comprised of vehicle and office equipment leases, have remaining terms that range from less than one year to 4.4 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.

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 $27.7 million and $22.9 million as of June 30, 2022 and December 31, 2021, 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.

10.    Line of Credit

On July 13, 2021, the Company entered into a First Amendment to the 2018 Credit Agreement (the "Credit Agreement"). The Credit Agreement provides 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 2018 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. The Credit Agreement matures on July 13, 2026, extended from October 26, 2023 as set forth in the 2018 Credit Agreement.

Borrowings under the 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 Credit Agreement are guaranteed by certain of the Company’s subsidiaries.

As of June 30, 2022 and December 31, 2021, the Company had no outstanding borrowings. The Company was in compliance with the financial and other covenants under the Credit Agreement and no event of default existed.

11.    Stock-Based Compensation

The Company's Third Amended and Restated 2012 Heidrick & Struggles GlobalShare Program (the "Third A&R Program") provides for grants of stock options, stock appreciation rights, and other stock-based compensation awards that are valued based upon the grant date fair value of awards. These awards may be granted to directors, selected employees and independent contractors.

As of June 30, 2022, 3,674,161 awards have been issued under the Third A&R Program, including 754,580 forfeited awards, and 430,419 shares remain available for future awards. The Third A&R Program provides that no awards can be granted after May 28, 2028.

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,
	2022		2021		2022		2021
Salaries and benefits (1)	$	1,274	$	5,770	$	4,178	$	11,231
General and administrative expenses	405		345		405		345
Income tax benefit related to stock-based compensation included in net income	458		1,627		1,248		3,080

(1) Includes $2.1 million of income and $3.3 million of expense related to cash settled restricted stock units for the three months ended June 30, 2022 and 2021, respectively and $2.8 million of income and $5.8 million of expense related to cash-settled restricted stock units for the six months ended June 30, 2022 and 2021, 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.

Restricted stock unit activity for the six months ended June 30, 2022 is as follows:

	Number of Restricted Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2021	727,651	$	31.32
Granted	192,279	37.99
Vested and converted to common stock	(149,250)	32.15
Forfeited	(9,703)	35.68
Outstanding on June 30, 2022	760,977	$	32.79

As of June 30, 2022, there was $9.9 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.3 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, 2022 is as follows:

	Number of Performance Stock Units	Weighted- Average Grant-Date Fair Value
Outstanding on December 31, 2021	232,857	$	39.88
Granted	97,379	49.59
Vested and converted to common stock	(69,784)	52.91
Forfeited	—
Outstanding on June 30, 2022	260,452	$	40.02

As of June 30, 2022, there was $7.2 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 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 $2.1 million and expense of $3.3 million during the three months ended June 30, 2022 and 2021, respectively and $2.8 million of income and $5.8 million of expense related to phantom stock units for the six months ended June 30, 2022 and 2021, respectively.

Phantom stock unit activity for the six months ended June 30, 2022 is as follows:

	Number of Phantom Stock Units
Outstanding on December 31, 2021	348,863
Granted	—
Vested	—
Forfeited	—

12. Restructuring

During the year ended December 31, 2020, the Company implemented a restructuring plan (the "2020 Plan") to optimize future growth and profitability. The primary components of the 2020 Plan included a workforce reduction, a reduction of the Company's real estate expenses and professional fees, and the elimination of certain deferred compensation programs. The Company continued to incur charges related to the 2020 Plan during the year ended December 31, 2021, which primarily related to finalizing a reduction of the Company's real estate footprint.

The Company did not incur any charges under the 2020 Plan during the three and six months ended June 30, 2022 and does not anticipate incurring any future charges under the 2020 Plan.

As part of the Company's reduction in real estate expenses under the 2020 Plan, a lease component related to one of the Company's offices was abandoned. In September 2021, the Company entered into a termination and surrender agreement for this lease component. Under the terms of the agreement, the Company made a one-time payment of $11.7 million to release the Company from all remaining obligations under the lease. At the time of payment, the Company had accrued approximately $17.4 million of lease liabilities related to future payments under the remaining lease term. Upon making the one-time payment, the lease liabilities were relieved, resulting in a gain on termination of approximately $5.7 million, which is recorded in Restructuring charges in the Consolidated Statements of Comprehensive Income (Loss) for the year ended December 31, 2021.

Changes in the restructuring accrual for the six months ended June 30, 2022 were as follows:

15.    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:

16.    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, 2022. The Company has not accrued for these arrangements as no event of default exists or is expected to exist.

17.    Commitments and Contingencies

Litigation

The Company has contingent liabilities from various pending claims and litigation matters arising in the ordinary course of the Company’s business, some of which involve claims for damages that are substantial in amount. Some of these matters are covered in part by insurance. Based upon information currently available, the Company believes the ultimate resolution of such claims and litigation will not have a material adverse effect on its financial condition, results of operations or liquidity.

Executive Overview

Our Business. Heidrick & Struggles International, Inc. (the "Company," "we," "us," or "our") is a human capital leadership advisory firm providing executive search, consulting and on-demand talent services to businesses and business leaders worldwide by helping them to improve the effectiveness of their leadership teams. We provide our services to a broad range of clients through the expertise of over 450 consultants located in major cities around the world. The Company and its predecessors have been leadership advisors for more than 60 years.

Our service offerings include the following:

Executive Search. We partner with our clients - respected organizations across the globe - to help them build and sustain the best leadership teams in the world, with a specialized focus on the placement of top-level senior executives. Through our unique relationship-based, data-driven approach, we help our clients find the right leaders, set them up for success, and accelerate their and their team’s performance.

We believe focusing on top-level senior executives provides the opportunity for several competitive advantages including access to and influence with key decision makers, increased potential for recurring search and consulting engagements, higher fees per search, enhanced brand visibility, and a leveraged global footprint. Working at the top of client organizations also facilitates the attraction and retention of high-caliber consultants who desire to serve top industry executives and their leadership needs. Our executive search services derive revenue through the fees generated for each search engagement, which generally are based on the annual compensation for the placed executive. We provide our executive search services primarily on a retained basis.

21

We employ a global approach to executive search built on better insights, more data and faster decision making facilitated by the use of our Infinity Framework and Heidrick Connect. Our Infinity Framework allows clients to holistically evaluate a candidate's pivotal experience and expertise, leadership capabilities, agility and potential, and culture fit and impact, thereby allowing our clients to find the right person for the role. We supplement our Infinity Framework through a series of additional online tools including our Leadership Accelerator, Leadership Signature and Culture Signature assessments. Heidrick Connect, a completely digital, always available client experience portal allows our clients to access talent insights for each engagement, including the Infinity Framework and other internally developed assessment tools. 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.

On-Demand Talent. Our on-demand services provide clients with seamless on-demand access to top independent talent, including professionals with deep industry and functional expertise for interim leadership roles and critical, project-based initiatives. Our unique model delivers the right independent talent on demand by blending proprietary data and technology with a dedicated Talent Solutions team.

Heidrick Consulting. As a complement and extension of our search services, we partner with organizations through Heidrick Consulting to unlock the power of their people. Our tools and experts use data and technology to bring science to the art of human capital development and organizational design. Our services allow our clients to accelerate their strategies and the effectiveness of individual leaders, teams and organizations as a whole.

Heidrick Consulting offers our clients groundbreaking approaches to human capital development through a myriad of solutions, ranging from leadership assessment and development, team and organization acceleration, digital acceleration and innovation, diversity and inclusion advisory services, and culture shaping. Applying our deep understanding of the behaviors and attributes of leaders across many of the world’s premier companies, we guide our clients as they build a thriving culture of future-ready leadership. These premium services and offerings, which complement our Executive Search expertise, significantly contribute to our ability to deliver a full-service human capital consulting solution to our clients.

We continue to focus on increasing the scale and impact of our Heidrick Consulting business and expect to improve the operating margins of this important business as we do so. Our consulting services generate revenue primarily through the professional fees generated for each engagement which are generally based on the size of the project and scope of services. Our

Heidrick Consulting teams have pivoted to create new digital solutions for Leadership Assessments, Team Acceleration, and Organization and Culture Acceleration that can be delivered virtually in response to the global pandemic.

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, 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 deferred 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 quarter of the following year and for an additional three-year vesting period.

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 quarter of 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 Condensed Consolidated Balance Sheets.

Third Quarter 2022 Outlook

The Company expects 2022 third quarter consolidated net revenue of between $260 million and $270 million, while acknowledging that some continued fluidity in external factors such as foreign conflicts, inflation, the interest rate and foreign exchange rate environments may impact quarterly results. In addition, this outlook is based on the average currency rates in June 2022 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.

23

Our 2022 third quarter guidance is subject to a number of risks and uncertainties, including those discussed under Item 1A - Risk Factors in our 2021 Annual Report on Form 10-K, 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.

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 quarter following the year in which they are earned. Employee bonuses are accrued throughout the year and are based on our performance and the performance of the individual employee.

Lines of credit. On July 13, 2021, the Company entered into a First Amendment to the 2018 Credit Agreement (the "Credit Agreement"). The Credit Agreement provides 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 2018 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. The Credit Agreement matures on July 13, 2026, extended from October 26, 2023 as set forth in the 2018 Credit Agreement.

Borrowings under the 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 Credit Agreement are guaranteed by certain of the Company’s subsidiaries.

As of June 30, 2022 and December 31, 2021, the Company had no outstanding borrowings. The Company was in compliance with the financial and other covenants under the Credit Agreement and no event of default existed.

Cash, cash equivalents and marketable securities. Cash, cash equivalents and marketable securities at June 30, 2022, December 31, 2021, and June 30, 2021 were $336.6 million, $545.2 million and $237.8 million, respectively. The $336.6 million of cash, cash equivalents and marketable securities at June 30, 2022 includes $118.3 million held by our foreign subsidiaries. A portion of the $118.3 million is considered permanently reinvested in these foreign subsidiaries. If these funds were required to satisfy obligations in the U.S., the repatriation of these funds could cause us to incur additional U.S. income taxes or foreign withholding taxes.

Cash flows used in operating activities. Cash used in operating activities was $179.5 million for the six months ended June 30, 2022, primarily reflecting decreases in accrued expenses of $124.3 million and increases in accounts receivable of $84.8 million, partially offset by net income of $42.6 million. The decrease in accrued expenses is primarily due to cash bonus payments related to 2021 and prior year cash bonus deferrals of $383.1 million, partially offset by 2022 bonus accruals.

Cash used in operating activities was $52.3 million for the six months ended June 30, 2021. This use of cash was primarily the result of cash bonus payments related to 2020 and prior year cash bonus deferrals of $200.3 million partially offset by 2021 bonus accruals and an increase in accounts receivable of $71.0 million associated with an increase in revenue. Other uses of cash included an increase in other assets of $18.4 million associated with unbilled receivables, right-of-use assets and long-term prepaid expenses, an increase in prepaid expenses of $6.0 million, and payments on the restructuring accrual of $4.7 million. These uses of cash were partially offset by net income of $35.6 million, depreciation and amortization of $12.0 million and stock compensation of $5.9 million.

Cash flows provided by (used in) investing activities. Cash used in investing activities was $8.6 million for the six months ended June 30, 2022, due to capital expenditures of $4.2 million related to office build-outs, and the purchase of marketable securities and investments of $5.4 million, partially offset by the proceeds from sales of marketable securities and investments of $1.0 million.

Cash used in investing activities was $16.0 million for the six months ended June 30, 2021, due to the acquisition of Business Talent Group of $32.0 million, capital expenditures of $2.7 million, and the purchase of marketable securities of $1.7 million, partially offset by the maturity of marketable securities of $20.3 million.

33

Cash flows used in financing activities. Cash used in financing activities was $9.4 million for the six months ended June 30, 2022, due to dividend payments of $6.2 million and employee tax withholding payments on equity transactions of $3.2 million.

Cash used in financing activities was $9.2 million for the six months ended June 30, 2021, due to dividend payments of $6.1 million and employee tax withholding payments on equity transactions of $3.1 million.

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

Application of Critical Accounting Policies and Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our Condensed Consolidated Financial Statements, which have been prepared using accounting principles generally accepted in the United States of America. Our significant accounting policies are discussed in Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the U.S. Securities and Exchange Commission (“SEC”) on February 28, 2022, and in Note 2, Summary of Significant Accounting Policies, in the Notes to Condensed Consolidated Financial Statements included in Item 1. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. If actual amounts are ultimately different from previous estimates, the revisions are included in our results of operations for the period in which the actual amounts become known.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or if changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. Management believes its critical accounting policies that reflect its more significant estimates and assumptions relate to revenue recognition, income taxes, interim effective tax rate and assessment of goodwill and other intangible assets for impairment. See Application of Critical Accounting Policies and Estimates in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 28, 2022.

Recently Issued and Adopted Financial Accounting Standards

The information presented in Note 2, Summary of Significant Accounting Policies, to our Condensed Consolidated Financial Statements within this Quarterly Report on Form 10-Q is incorporated herein by reference.

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 $2.1 million for the six months ended June 30, 2022. For financial information by segment, see Note 15, 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

34

the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Any system of controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Management of the Company, with the participation of the principal executive officer and the principal financial officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of June 30, 2022. 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, 2022.

(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, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The information presented in Note 17, Commitments and Contingencies, to our Condensed Consolidated Financial Statements within this Quarterly Report on Form 10-Q is incorporated herein by reference.

Item 1A. Risk Factors

The business, financial condition and operating results of the Company can be affected by a number of factors, whether currently known or unknown, including but not limited to those described in Part I, Item 1A of the Company's 2021 Annual Report on Form 10-K under the heading “Risk Factors,” any one or more of which could, directly or indirectly, cause the Company’s actual financial condition and operating results to vary materially from past, or from anticipated future, financial condition and operating results. Any of these factors, in whole or in part, could materially and adversely affect the Company’s business, financial condition, operating results and stock price. There have been no material changes to the Company’s risk factors from those set forth in the Company's Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on February 28, 2022.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure	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, 2022 and December 31, 2021, the results of operations for the three and six months ended June 30, 2022 and 2021 and its cash flows for the six months ended June 30, 2022 and 2021 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, 2021, as filed with the SEC on February 28, 2022.

Earnings per Common Share

Basic earnings per common share is 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,
	2022		2021		2022		2021

Diluted earnings per share	$	1.19	$	1.03	$	2.08	$	1.76

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.

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, 2022. The new guidance is not expected to have a material effect on the Company's financial statements.

Revenue from Contract with Customer

Jun. 30, 2022

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

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, 2021 to June 30, 2022:

	June 30, 2022		December 31, 2021		Change
Contract assets
Unbilled receivables, net	$	19,592	$	17,947	$	1,645
Contract assets	21,639		18,995		2,644
Total contract assets	41,231		36,942		4,289
Contract liabilities
Deferred revenue	$	48,764	$	51,404	$	(2,640)

During the six months ended June 30, 2022, the Company recognized revenue of $42.3 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, 2022, from performance obligations partially satisfied in previous periods as a result of changes in the estimates of variable consideration was $12.7 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]

Loans, Notes, Trade and Other Receivables Disclosure

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, 2021	$	5,666
Provision for credit losses	3,966
Write-offs	(2,876)
Foreign currency translation	(110)
Balance at June 30, 2022	$	6,646

The Company had zero available for sale debt securities in an unrealized loss position at June 30, 2022 and December 31, 2022.

Leases [Abstract]

Lessee, Operating 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 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 11.0 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.

As part of the Company's 2020 Plan (as defined below), a lease component related to one of the Company's offices was abandoned and the useful life of the associated right-of-use asset was shortened to correspond with the cease-use date. As a result of the change in the useful life, approximately $3.5 million and $7.5 million of right-of-use asset amortization was accelerated and recorded in Restructuring charges in the Condensed Consolidated Statements of Comprehensive Income and Depreciation and amortization in the Condensed Consolidated Statements of Cash Flows during the three and six months ended June 30, 2021, respectively.

Equipment leases, which are comprised of vehicle and office equipment leases, have remaining terms that range from less than one year to 4.4 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,

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 $27.7 million and $22.9 million as of June 30, 2022 and December 31, 2021, 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 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, 2022:

	Earnout		Contingent Compensation

During the year ended December 31, 2020, the Company implemented a restructuring plan (the "2020 Plan") to optimize future growth and profitability. The primary components of the 2020 Plan included a workforce reduction, a reduction of the Company's real estate expenses and professional fees, and the elimination of certain deferred compensation programs. The Company continued to incur charges related to the 2020 Plan during the year ended December 31, 2021, which primarily related to finalizing a reduction of the Company's real estate footprint.

The Company did not incur any charges under the 2020 Plan during the three and six months ended June 30, 2022 and does not anticipate incurring any future charges under the 2020 Plan.

As part of the Company's reduction in real estate expenses under the 2020 Plan, a lease component related to one of the Company's offices was abandoned. In September 2021, the Company entered into a termination and surrender agreement for this lease component. Under the terms of the agreement, the Company made a one-time payment of $11.7 million to release the Company from all remaining obligations under the lease. At the time of payment, the Company had accrued approximately $17.4 million of lease liabilities related to future payments under the remaining lease term. Upon making the one-time payment, the lease liabilities were relieved, resulting in a gain on termination of approximately $5.7 million, which is recorded in Restructuring charges in the Consolidated Statements of Comprehensive Income (Loss) for the year ended December 31, 2021.

Segment Reporting [Abstract]

Segment Reporting Disclosure

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:

Earnings Per Share, Policy

Earnings per Common Share

Basic earnings per common share is 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:

Lessee, 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.
