Equity Incentive Plans

12 Months Ended

Dec. 31, 2023

Share-Based Payment Arrangement [Abstract]

Equity Incentive Plans

We grant share-based awards under the Company's 2012 Omnibus Incentive Plan (the “2012 Plan”) which permits the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and other share-based or cash-based awards valued in whole or in part by reference to, or otherwise based on, our common stock. Subsequent to the initial approval of the 2012 Plan and through December 31, 2023, our shareholders approved amendments to the 2012 Plan to increase the number of shares authorized for issuance to 5.4 million, in the aggregate. As of December 31, 2023, 1.1 million shares remain available for issuance under the 2012 Plan.

On May 1, 2015, we adopted the Stock Ownership Participation Program (the “SOPP”), which is available to Huron employees below the principal and managing director level who do not receive equity-based awards as part of their normal compensation plan. Under the SOPP, eligible employees may elect to use after-tax payroll deductions or cash contributions to purchase shares of the Company’s common stock on certain designated purchase dates. Employees who purchase stock under the SOPP are granted restricted stock equal to 25% of their purchased shares. Vesting of the restricted stock is subject to both a time-based vesting schedule and a requirement that the purchased shares be held for a specified period. Subsequent to the initial approval of the SOPP and through December 31, 2023, our shareholders approved amendments to the SOPP to increase the total number of shares authorized for issuance to 0.7 million, in the aggregate. As of December 31, 2023, 0.1 million shares remain available for issuance under the SOPP.

It has been our practice to issue shares of common stock upon exercise of stock options and granting of restricted stock from authorized but unissued shares, with the exception of the SOPP under which shares are issued from treasury stock. Certain grants of restricted stock under the 2012 Plan may be issued from treasury stock at the direction of the Compensation Committee. The Compensation Committee of the board of directors has the responsibility of interpreting the 2012 Plan and SOPP and determining all of the terms and conditions of awards made under the plans, including when the awards will become exercisable or otherwise vest.

Share-based awards outstanding under our 2012 Plan provide for a retirement eligibility provision, under which eligible employees who have reached 62 years of age and have completed seven years of employment with Huron will continue vesting in their share-based awards after retirement, subject to certain conditions.

Total share-based compensation cost recognized for the years ended December 31, 2023, 2022, and 2021 was $45.7 million, $31.0 million, and $25.9 million, respectively, with related income tax benefits of $9.3 million, $6.8 million, and $6.3 million, respectively. As of December 31, 2023, there was $42.8 million of total unrecognized compensation cost related to nonvested share-based awards. This cost is expected to be recognized over a weighted average period of 2.2 years.

Restricted Stock

The grant date fair values of our restricted stock are measured based on the fair value of our common stock at grant date and amortized into expense over the service period. Subject to acceleration under certain conditions, the majority of our restricted stock vests annually over four years.

The table below summarizes the restricted stock activity for the year ended December 31, 2023.


	Number of Shares			Weighted Average Grant Date Fair Value (in dollars)
	2012 Omnibus Incentive Plan	Stock Ownership Participation Program	Total
Nonvested restricted stock at December 31, 2022	971	18	989	$	52.40
Granted	354	18	372	$	80.84
Vested	(361)	(17)	(378)	$	53.11
Forfeited	(38)	(2)	(40)	$	59.30
Nonvested restricted stock at December 31, 2023	926	17	943	$	63.00

The aggregate fair value of restricted stock that vested during the years ended December 31, 2023, 2022, and 2021 was $27.6 million, $18.4 million, and $19.8 million, respectively. The weighted average grant date fair value per share of restricted stock granted during 2022 and 2021 was $49.69 and $53.84, respectively.

Performance-based Share Awards

The total number of shares earned by recipients of performance-based share awards is contingent upon meeting practice specific and/or company-wide performance goals. Following the performance period, certain awards are subject to the completion of a service period, which is generally an additional two years. These earned awards vest on a graded vesting schedule over the service period. For certain performance awards, the recipients may earn additional shares of stock for performance achieved above the stated target. The grant date fair values of our performance-based share awards are measured based on the fair value of our common stock at grant date. Compensation cost is amortized into expense over the service period, including the performance period.

The table below summarizes the performance-based stock activity for the year ended December 31, 2023. All nonvested performance-based stock outstanding at December 31, 2023 and 2022 was granted under the 2012 Omnibus Incentive Plan.


	Number of Shares	Weighted Average Grant Date Fair Value (in dollars)
Nonvested performance-based stock at December 31, 2022	478	$	50.36
Granted (1)	170	$	80.89
Vested	(84)	$	51.84
Forfeited (2)	(110)	$	53.78
Nonvested performance-based stock at December 31, 2023 (3)	454	$	60.72

(1)Shares granted in 2023 are presented at the stated target, which represents the base number of shares that could be earned. Actual shares earned may be below or, for certain grants, above the target based on the achievement of specific financial goals.

(2)Forfeited shares include shares forfeited as a result of not meeting the performance criteria of the award as well as shares forfeited upon termination.

(3)Of the 454,000 nonvested performance-based shares outstanding as of December 31, 2023, 355,299 shares were unearned and subject to achievement of specific financial goals. Once earned, the awards will be subject to time-based vesting according to the terms of the award. Based on 2023 financial results, approximately 16,328 of the 355,299 unearned shares will be forfeited in the first quarter of 2024.

The aggregate fair value of performance-based stock that vested during the years ended December 31, 2023, 2022, and 2021 was $5.9 million, $5.8 million, and $9.8 million, respectively. The weighted average grant date fair value per share of performance-based stock granted during 2022 and 2021 was $48.22 and $53.75, respectively.

Performance-based Stock Options

Beginning in 2022, the Company granted performance-based stock options which are earned by the recipients contingent upon meeting practice specific goals. Following the performance period, these awards are subject to the completion of a service period of an additional two years. These earned awards vest on a graded vesting schedule over the service period. The performance-based stock options were granted at exercise prices equal to the fair value of the Company’s common stock on the date of grant. Compensation cost is amortized into expense over the service period, including the performance period. Our performance-based stock options have a contractual term of 7 years.

The fair values of the performance-based stock options granted during 2023 and 2022 were calculated using the Black-Scholes option pricing model using the following assumptions:


	2023	2022
Black-Scholes performance-based option pricing model:
Expected dividend yield	—%	—%
Expected volatility	40.0%	40.0%
Risk-free rate	4.4%	1.6% / 2.6%
Expected option life (in years)	4.5 years	4.5 years

Expected volatility was based on our historical stock prices as we believe that our historical volatility provides the most reliable indication of future volatility and sufficient historical daily stock price observations are available. The risk-free interest rate was based on the rate of U.S. Treasury bills with an equivalent expected term of the stock options at the time of the option grant. The expected option life was estimated using the simplified method, which is a weighted average of the vesting term and the contractual term, to determine the expected term.The simplified method was used due to the lack of sufficient data available to provide a reasonable basis upon which to estimate the expected term.

Performance-based stock option activity for the year ended December 31, 2023 was as follows:


	Number of Performance-based Options (in thousands)	Weighted Average Exercise Price (in dollars)		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Outstanding at December 31, 2022	171	$	48.19	6.2	$	4.2
Granted (2)	88	$	81.54
Exercised	(20)	$	48.22		$	0.8
Forfeited or expired	(58)	$	50.54
Outstanding at December 31, 2023 (1)(3)	181	$	63.73	5.5	$	7.1
Exercisable at December 31, 2023	21	$	48.13	5.2	$	1.1

(1)All of the outstanding performance-based stock options were granted under the 2012 Omnibus Incentive Plan.

(2)Performance-based stock options granted in 2023 are presented at the stated target, which represents the base number of options that could be earned. Actual options earned may be below or, for certain grants, above the target based on the achievement of specific financial goals.

(3)Of the 181,000 outstanding performance-based stock options as of December 31, 2023, 84,249 were unearned and subject to achievement of specific financial goals. Once earned, the options will be subject to time-based vesting according to the terms of the award. Based on 2023 financial results, approximately 13,751 of the 84,249 unearned options will be forfeited in the first quarter of 2024.

The weighted average grant date fair value of the performance-based stock options granted during 2023 and 2022 was $32.27 and $17.00, respectively. No performance-based stock options were granted in 2021. No performance-based stock options were exercised in 2022 and 2021.

Time-vested Stock Options

In prior years, we have granted stock options to certain employees that are solely earned based on the completion of the stated service period. These time-vested stock options were granted at exercise prices equal to the fair value of the Company’s common stock on the date

of grant. No time-vested stock option awards were granted in 2023 or 2022. Subject to acceleration under certain conditions, these time-vested stock options vest annually over four years. Our time-vested stock options have a contractual term between 7 and 10 years.

The fair value of the time-vested stock options granted during 2021 were calculated using the Black-Scholes option pricing model using the following assumptions:


			2021
Black-Scholes time-vested option pricing model:
Expected dividend yield			—%
Expected volatility			40.0%
Risk-free rate			0.9%
Expected option life (in years)			4.75 years

Expected volatility was based on our historical stock prices as we believe that our historical volatility provides the most reliable indication of future volatility and sufficient historical daily stock price observations are available. The risk-free interest rate was based on the rate of U.S. Treasury bills with an equivalent expected term of the stock options at the time of the option grant. The expected option life was estimated using the simplified method, which is a weighted average of the vesting term and the contractual term, to determine the expected term. The simplified method was used due to the lack of sufficient data available to provide a reasonable basis upon which to estimate the expected term.

Time-vested stock option activity for the year ended December 31, 2023 was as follows:


	Number of Time-vested Options (in thousands)	Weighted Average Exercise Price (in dollars)		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Outstanding at December 31, 2022	56	$	51.05	5.2	$	1.2
Granted	—
Exercised	(31)	$	49.90		$	1.5
Forfeited or expired	—
Outstanding at December 31, 2023 (1)	25	$	52.49	4.7	$	1.3
Exercisable at December 31, 2023	—

(1)All of the outstanding time-vested stock options were granted under the 2012 Omnibus Incentive Plan.

The weighted average grant date fair value of the time-vested stock options granted during 2021 was $18.42. No time-vested stock options were granted in 2023 and 2022. The aggregate intrinsic value of time-vested stock options exercised during 2022 and 2021 was $0.5 million and $0.4 million, respectively.

Commitments, Contingencies and Guarantees	Dec. 31, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Lease Commitments We lease office space, data centers and certain equipment under non-cancelable operating lease arrangements expiring on various dates through 2030, with various renewal options. Office facilities under operating leases include fixed payments plus, in some cases, scheduled base rent increases over the term of the lease. Certain leases require variable payments of real estate taxes, insurance and operating expenses. See Note 5 “Leases” for additional information on our leases, including the remaining expected lease payments under our operating leases as of December 31, 2023. Litigation From time to time, we are involved in legal proceedings and litigation arising in the ordinary course of business. As of the date of this Annual Report on Form 10-K, we are not a party to any litigation or legal proceeding or subject to any claim that, in the current opinion of management, could reasonably be expected to have a material adverse effect on our financial position or results of operations. However, due to the risks and uncertainties inherent in legal proceedings, actual results could differ from current expected results. Guarantees Guarantees in the form of letters of credit totaling $0.5 million and $0.7 million were outstanding at December 31, 2023 and 2022, respectively, to support certain office lease obligations. In connection with certain business acquisitions, we may be required to pay post-closing consideration to the sellers if specific financial performance targets are met over a number of years as specified in the related purchase agreements. As of December 31, 2023 and 2022, the total estimated fair value of our outstanding contingent consideration liability was $2.1 million and $3.2 million, respectively. To the extent permitted by law, our bylaws and articles of incorporation require that we indemnify our officers and directors against judgments, fines and amounts paid in settlement, including attorneys’ fees, incurred in connection with civil or criminal action or proceedings, as it relates to their services to us if such person acted in good faith. Although there is no limit on the amount of indemnification, we may have recourse against our insurance carrier for certain payments made.

Summary of Significant Accounting Policies	12 Months Ended
Summary of Significant Accounting Policies	Dec. 31, 2023
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements reflect the financial position at December 31, 2023 and 2022, and the results of operations and cash flows for the years ended December 31, 2023, 2022, and 2021. The consolidated financial statements include the accounts of Huron Consulting Group Inc. and its subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Actual results may differ from these estimates and assumptions. Revenue Recognition We generate substantially all of our revenues from providing professional services to our clients. We also generate revenues from software licenses; software support and maintenance and subscriptions to our cloud-based analytic tools and solutions; speaking engagements; conferences; and publications. A single contract could include one or multiple performance obligations. For those contracts that have multiple performance obligations, we allocate the total transaction price to each performance obligation based on its relative standalone selling price, which is determined based on our overall pricing objectives, taking into consideration market conditions and other factors. Revenue is recognized when control of the goods and services provided are transferred to our customers and in an amount that reflects the consideration we expect to be entitled to in exchange for those goods and services using the following steps: 1) identify the contract, 2) identify the performance obligations, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue as or when we satisfy the performance obligations. We generate our revenues under four types of billing arrangements: fixed-fee (including software license revenue); time-and-expense; performance-based; and software support, maintenance and subscriptions. •Fixed-fee (including software license revenue): In fixed-fee billing arrangements, we agree to a pre-established fee in exchange for a predetermined set of professional services. We set the fees based on our estimates of the costs and timing for completing the engagements. We generally recognize revenues under fixed-fee billing arrangements using a proportionate performance approach, which is based on work completed to date versus our estimates of the total services to be provided under the engagement. Contracts within our culture and organizational excellence solution include fixed-fee partner contracts with multiple performance obligations, which primarily consist of coaching services, as well as speaking engagements, conferences, publications and software products (“Partner Contracts”). Revenues for coaching services and software products are generally recognized on a straight-line basis over the length of the contract. All other revenues under Partner Contracts, including speaking engagements, conferences and publications, are recognized at the time the goods or services are provided. Estimates of total engagement revenues and cost of services are monitored regularly during the term of the engagement. We also generate revenues from software licenses for our revenue cycle management software and research administration and compliance software. Licenses for our revenue cycle management software are sold only as a component of our consulting projects, and the services we provide are essential to the functionality of the software. Therefore, revenues from these software licenses are recognized over the term of the related consulting services contract. License revenue from our research administration and compliance software is generally recognized in the month in which the software is delivered. •Time-and-expense: Under time-and-expense billing arrangements, we invoice our clients based on the number of hours worked by our revenue-generating professionals at agreed upon rates. Time-and-expense arrangements also include certain speaking engagements, conferences, and publications purchased by our clients outside of Partner Contracts within our culture and organizational excellence solution and the portion of our Healthcare managed services contracts that are billed under time-and-expense arrangements. We recognize revenues under time-and-expense arrangements as the related services or publications are provided, using the right to invoice practical expedient which allows us to recognize revenue in the amount that we have a right to invoice based on the number of hours worked and the agreed upon hourly rates or the value of the speaking engagements, conferences or publications purchased by our clients. •Performance-based: In performance-based billing arrangements, fees are tied to the attainment of contractually defined objectives. We enter into performance-based engagements in essentially two forms. First, we generally earn fees that are directly related to the savings formally acknowledged by the client as a result of adopting our recommendations for improving operational and cost effectiveness in the areas we review. Second, we earn a success fee when and if certain predefined outcomes occur. We recognize revenue under performance-based billing arrangements using the following steps: 1) estimate variable consideration using a probability-weighted assessment of the fees to be earned, 2) apply a constraint to the estimated variable consideration to limit the amount that could be reversed when the uncertainty is resolved (the “constraint”), and 3) recognize revenue of estimated variable consideration, net of the constraint, based on work completed to date versus our estimates of the total services to be provided under the engagement. •Software support, maintenance and subscriptions: Clients that have purchased one of our software licenses can pay an annual fee for software support and maintenance. We also generate subscription revenue from our cloud-based analytic tools and solutions. Software support, maintenance and subscription revenues are recognized ratably over the support or subscription period. These fees are generally billed in advance and included in deferred revenues until recognized. Provisions are recorded for the estimated realization adjustments on all engagements, including engagements for which fees are subject to review by the bankruptcy courts. Reimbursable expenses that are billed to clients, primarily relating to travel and out-of-pocket expenses incurred in connection with client engagements, are included in total revenues and reimbursable expenses. Reimbursable expenses are recognized as expenses in the period in which the expense is incurred. The payment terms and conditions in our customer contracts vary. Differences between the timing of billings and the recognition of revenue are recognized as either unbilled services or deferred revenues in the consolidated balance sheets. Revenues recognized for services performed but not yet billed to clients are recorded as unbilled services. Revenues recognized, but for which we are not yet entitled to bill because certain events, such as the completion of the measurement period or client approval, must occur, are recorded as contract assets and included within unbilled services. Client prepayments and retainers are classified as deferred revenues and recognized over future periods as earned in accordance with the applicable engagement agreement. Capitalized Sales Commissions Sales commissions earned by our sales professionals are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions with an expected amortization period greater than one year are deferred and amortized on a straight-line basis over the period of the associated contract. We elected to apply the practical expedient to expense sales commissions as incurred when the expected amortization period is one year or less. Amortization expense is recorded to direct costs. During the years ended December 31, 2023, 2022, and 2021, we amortized $0.2 million, $0.3 million, and $0.4 million, respectively, of capitalized sales commissions. Unamortized sales commissions were $0.4 million as of both December 31, 2023 and 2022. Allowances for Doubtful Accounts and Unbilled Services We maintain allowances for doubtful accounts and unbilled services based on several factors, including the estimated cash realization from amounts due from clients, an assessment of a client’s ability to make required payments, and the historical percentages of fee adjustments and write-offs by age of receivables and unbilled services. The allowances are assessed by management on a regular basis. These estimates may differ from actual results. If the financial condition of a client deteriorates in the future, impacting the client’s ability to make payments, an increase to our allowance might be required or our allowance may not be sufficient to cover actual write-offs. We record the provision for doubtful accounts and unbilled services as a reduction in revenue. To the extent we write-off accounts receivable due to a client's inability to pay, the charge is recognized as a component of selling, general and administrative expenses. Direct Costs Direct costs primarily consist of payroll costs for our revenue-generating professionals which includes salaries, performance bonuses, share-based compensation, signing and retention bonuses, payroll taxes and benefits. Direct costs also include fees paid to independent contractors that we retain to supplement our revenue-generating professionals, typically on an as-needed basis for specific client engagements, as well as technology costs, product and event costs, and commissions. Direct costs exclude amortization of intangible assets and software development costs and reimbursable expenses, both of which are separately presented in our consolidated statements of operations. Direct costs are expensed in the period incurred. Cash and Cash Equivalents We consider all highly liquid investments, including overnight investments and commercial paper, with original maturities of three months or less to be cash equivalents. Concentrations of Credit Risk To the extent receivables from clients become delinquent, collection activities commence. No single client balance is considered large enough to pose a material credit risk. The allowances for doubtful accounts and unbilled services are based upon the expected ability to collect accounts receivable and bill and collect unbilled services. Management does not anticipate incurring losses on accounts receivable in excess of established allowances. See Note 19 “Segment Information” for concentration of accounts receivable and unbilled services. We hold our cash in accounts at multiple third-party financial institutions. These deposits, at times, may exceed federally insured limits. We review the credit ratings of these financial institutions, regularly monitor the cash balances in these accounts, and adjust the balances as appropriate. However, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. Long-term Investments Our long-term investments consist of our convertible debt investment in Shorelight Holdings, LLC (“Shorelight”) and preferred stock investment in a hospital-at-home company. We classified the convertible debt investment in Shorelight as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. The investment is carried at fair value with unrealized holding gains and losses reported in other comprehensive income. If the investment is in an unrealized loss position due to significant credit deterioration of the investee, we recognize an allowance to decrease the carrying value of the investment to the fair value, which may be reversed in the event that the credit of an issuer improves. In the event there are realized gains and losses or credit allowances recognized, we will record the amount in earnings. We have not realized any gains or losses or recognized any credit allowance on our convertible debt investment as of December 31, 2023. See Note 13 “Fair Value of Financial Instruments” for additional information on our convertible debt investment. We classified the preferred stock investment in the hospital-at-home company as an equity security without a readily determinable value at the time of purchase and reevaluate such classification as of each balance sheet date. We elected to apply the measurement alternative at the time of purchase and will continue to do so until the investment does not qualify to be so measured. Under the measurement alternative, the investment is carried at cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment in the company. On a quarterly basis, we review the information available to determine whether an orderly and observable transaction for the same or similar equity instrument occurred or if factors indicate that a significant decrease in value has occurred. We remeasure to the fair value of the preferred stock using such identified information with changes in the fair value recorded in our consolidated statement of operations. See Note 13 “Fair Value of Financial Instruments” for additional information on our preferred stock investment, including the cumulative unrealized gains recognized since our initial investment and the impairment loss recognized in 2023. Fair Value of Financial Instruments See Note 13 “Fair Value of Financial Instruments” for the accounting policies used to measure the fair value of our financial assets and liabilities that are measured at fair value on a recurring basis. Property and Equipment Property and equipment is recorded at cost, less accumulated depreciation, and depreciated using the straight-line method over the shorter of the estimated useful life of the asset or the lease term. Software, computers, and related equipment are depreciated over an estimated useful life of two to four years. Furniture and fixtures are depreciated over five years. Leasehold improvements are amortized over the lesser of the estimated useful life of the asset or the initial term of the lease. Leases We determine if an arrangement contains a lease and the classification of such lease at inception. As of December 31, 2023 and 2022, all of our material leases are classified as operating leases; we have not entered into any material finance leases. For all operating leases with an initial term greater than 12 months, we recognize an operating lease right-of-use (“ROU”) asset and operating lease liability. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Operating lease ROU assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date and provided by the administrative agent for our senior secured credit facility in determining the present value of lease payments. Operating lease ROU assets exclude lease incentives. We elected the practical expedient to combine lease and nonlease components. Certain lease agreements contain variable lease payments that do not depend on an index or rate. These variable lease payments are not included in the calculation of the operating lease ROU asset and operating lease liability; instead, they are expensed as incurred. Our leases may contain options to extend or terminate the lease, and we include these terms in our calculation of the operating lease ROU asset and operating lease liability when it is reasonably certain that we will exercise the option. Operating lease expense is recognized on a straight-line basis over the lease term and recorded within selling, general and administrative expenses on our consolidated statement of operations. In accordance with our accounting policy for impairment of long-lived assets, operating lease ROU assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group to which the operating lease ROU asset is assigned may not be recoverable. We evaluate the recoverability of the asset group based on forecasted undiscounted cash flows. See Note 5 “Leases” for additional information on our leases, including the lease impairment charges recorded in 2023 and 2022. Software Development Costs We incur internal and external software development costs related to our cloud computing applications and software for internal use. We capitalize these software development costs incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Once the project is substantially complete and ready for its intended use, these costs are amortized on a straight-line basis over the technology's estimated useful life. Acquired technology assets are initially recorded at fair value and amortized on a straight-line basis over the estimated useful life. Development costs related to software products that will be sold, leased, or otherwise marketed are expensed until technological feasibility has been established. Thereafter, and until the software is available for general release to customers, these software development costs are capitalized and subsequently reported at the lower of unamortized cost or net realizable value. These capitalized development costs are amortized in proportion to current and future revenue for each product with an annual minimum equal to the straight-line amortization over the remaining estimated economic life of the product. We did not capitalize any material development costs for this type of software during 2023 or 2022. We classify capitalized software development costs, which primarily relate to cloud computing applications and software for internal use, as other non-current assets on our consolidated balance sheet. As of December 31, 2023, gross capitalized software development costs and related accumulated amortization was $72.3 million and $26.8 million, respectively. As of December 31, 2022, gross capitalized software development costs and related accumulated amortization was $47.7 million and $21.5 million, respectively. During the years ended December 31, 2023, 2022, and 2021, we amortized $6.5 million, $5.9 million, and $5.2 million, respectively, of capitalized software development costs. Additionally, in 2023, we recognized a $0.3 million restructuring charge for the abandonment of a capitalized software development project. Implementation Costs Incurred in a Cloud Computing Arrangement We incur costs to implement cloud computing arrangements that are service contracts. We capitalize certain costs associated with the implementation of the cloud computing arrangements, including employee payroll and related benefits and third party consulting costs, incurred during the application development stage of a project. These costs are amortized on a straight-line basis over the term of the hosting service contracts, including renewal periods we are reasonably certain to exercise, and recognized as a component of selling, general and administrative expenses on our consolidated statement of operations. As of December 31, 2023, gross capitalized implementation costs incurred in a cloud computing arrangement and related accumulated amortization was $7.2 million and $2.2 million, respectively. As of December 31, 2022, gross capitalized implementation costs incurred in a cloud computing arrangement and related accumulated amortization was $6.5 million and $1.5 million, respectively. During the years ended December 31, 2023, 2022 and 2021 we recognized amortization of our capitalized implementation costs of $0.7 million, $1.2 million and $0.9 million, respectively. Of the $1.2 million amortization for capitalized implementation costs in 2022, $0.3 million was recognized as a restructuring charge as it related to accelerated amortization of capitalized software implementation costs for a cloud-computing arrangement that is no longer in use. Our capitalized implementation costs primarily relate to the implementation of a new ERP system. In January 2021, we successfully went live with the new ERP system, and we continue to progress with additional functionality and integrations as scheduled. These capitalized costs are included as a component of prepaid expenses and other current assets and other non-current assets on our consolidated balance sheet. Intangible Assets Other Than Goodwill Identifiable intangible assets are amortized over their expected useful lives using a method that reflects the economic benefit expected to be derived from the assets or on a straight-line basis. We evaluate the recoverability of intangible assets periodically by considering events or circumstances that may warrant revised estimates of useful lives or that indicate the asset may be impaired. Impairment of Long-Lived Assets Long-lived assets, including property and equipment, right-of-use assets, and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Events relating to recoverability may include significant unfavorable changes in business conditions, recurring losses, or a significant decline in forecasted operating results over an extended period of time. We evaluate the recoverability of long-lived assets based on forecasted undiscounted cash flows. See Note 5 “Leases” and Note 11 “Restructuring Charges” for information on our operating lease ROU asset impairment charges recorded in 2023 and 2022 and fixed asset impairment charges recorded in 2023. No material impairment charges for other long-lived assets were recorded in 2023, 2022, or 2021. Goodwill For acquisitions accounted for as a business combination, goodwill represents the excess of the cost over the fair value of the net assets acquired. We are required to test goodwill for impairment, at the reporting unit level, annually and when events or circumstances indicate the fair value of a reporting unit may be below its carrying value. We perform our annual goodwill impairment test as of November 30 and monitor for interim triggering events on an ongoing basis. A reporting unit is an operating segment or one level below an operating segment (referred to as a component) to which goodwill is assigned when initially recorded. We assign goodwill to reporting units based on our integration plans and the expected synergies resulting from the acquisition. As of December 31, 2023, we have three reporting units: Healthcare, Education, and Commercial. In 2023, we performed the annual goodwill impairment test as of November 30, 2023, pursuant to our policy, and determined that no impairment of goodwill existed as of that date. Further, we evaluated whether any events have occurred, or any circumstances have changed since November 30, 2023 that would indicate goodwill may have become impaired since our annual impairment test. Based on our evaluation as of December 31, 2023, we determined that no indications of impairment have arisen since our annual goodwill impairment test. In 2022, we performed two goodwill impairment tests: an interim impairment test for each of our reporting units as of January 1, 2022 in connection with the operating model modification and the annual impairment test for each of our reporting units as of November 30. We did not identify any impairments during our interim or annual impairment tests performed during 2022. In 2021, we performed the annual goodwill impairment test as of November 30, 2021, pursuant to our policy, and determined that no impairment of goodwill existed as of that date. See Note 4 “Goodwill and Intangible Assets” for additional information on our interim and annual goodwill impairment tests. Business Combinations We use the acquisition method of accounting for business combinations. Each acquired company’s operating results are included in our consolidated financial statements starting on the date of acquisition. The purchase price is equivalent to the fair value of consideration transferred. The contract assets and contract liabilities acquired are recorded at their carrying value under Topic 606: Revenue from Contracts with Customers. All other tangible assets and identifiable intangible assets acquired and liabilities assumed are recorded at fair value as of the acquisition date. Goodwill is recognized for the excess of purchase price over the net value of tangible and intangible assets acquired and liabilities assumed. Contingent consideration, which is primarily based on the business achieving certain performance targets, is recognized at its fair value on the acquisition date, and changes in fair value are recognized in earnings until settled. Refer to Note 3 “Acquisitions and Divestiture” for additional information on our business acquisitions and refer to Note 13 “Fair Value of Financial Instruments” for additional information regarding our contingent acquisition liability balances. Income Taxes Current tax liabilities and assets are recognized for the estimated taxes payable or refundable, respectively, on the tax returns for the current year. We have elected to recognize the tax expense related to Global Intangible Low-Taxed Income (“GILTI”) as a current period expense when incurred. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. To the extent that deferred tax assets will not likely be recovered from future taxable income, a valuation allowance is established against such deferred tax assets. Refer to Note 17 “Income Taxes” for further information regarding incomes taxes. Share-Based Compensation Share-based compensation cost is measured based on the grant date fair value of the respective awards. We generally recognize share-based compensation ratably using the straight-line attribution method; however, for those awards with performance criteria and graded vesting features, we use the graded vesting attribution method. It is our policy to account for forfeitures as they occur. Refer to Note 16 “Equity Incentive Plan” for further information regarding share-based compensation. Sponsorship and Advertising Costs Sponsorship and advertising costs are expensed as incurred. Such expenses for the years ended December 31, 2023, 2022, and 2021 totaled $7.3 million, $6.3 million, and $4.3 million, respectively, and are a component of selling, general and administrative expenses on our consolidated statement of operations. Debt Issuance Costs We amortize the costs we incur to obtain debt financing over the contractual life of the related debt using the straight-line method. The amortization expense is included in interest expense, net of interest income in our statement of operations. Unamortized debt issuance costs attributable to our senior secured revolving credit facility are included as a component of other non-current assets. Foreign Currency Assets and liabilities of foreign subsidiaries whose functional currency is not the United States Dollar (USD) are translated into USD using the exchange rates in effect at period end. Revenue and expense items are translated using the average exchange rates for the period. Foreign currency translation adjustments are included in accumulated other comprehensive income, which is a component of stockholders’ equity. Foreign currency transaction gains and losses are included in other income, net on the consolidated statement of operations. We recognized $0.5 million of foreign currency transaction losses in 2023, $0.7 million of foreign currency transaction gains in 2022, and $0.4 million of foreign currency transaction losses in 2021. Segment Reporting Segments are defined as components of a company that engage in business activities from which they may earn revenues and incur expenses, and for which separate financial information is available and is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. As of December 31, 2023, our chief operating decision maker manages the business under three operating segments, which are our reportable segments: Healthcare, Education, and Commercial. New Accounting Pronouncements Not Yet Adopted On November 27, 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which updates the segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an interim and annual basis. ASU 2023-07 will be effective for our annual reporting periods beginning with the fiscal year ending December 31, 2024 and for interim reporting periods beginning in fiscal year 2025, with early adoption permitted, and is required to be applied retrospectively. We are currently evaluating the impact this guidance will have on our disclosures within our consolidated financial statements. On December 14, 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which updates annual income tax disclosures by requiring disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 will be effective for our annual reporting periods beginning with the fiscal year ending December 31, 2024, with early adoption permitted, and is required to be applied prospectively with the option of retrospective application. We are currently evaluating the impact this guidance will have on our disclosures within our consolidated financial statements.

Summary of Significant Accounting Policies

12 Months Ended

Dec. 31, 2023

Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of Huron Consulting Group Inc. and its subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Actual results may differ from these estimates and assumptions.

Revenue Recognition

We generate substantially all of our revenues from providing professional services to our clients. We also generate revenues from software licenses; software support and maintenance and subscriptions to our cloud-based analytic tools and solutions; speaking engagements; conferences; and publications. A single contract could include one or multiple performance obligations. For those contracts that have multiple performance obligations, we allocate the total transaction price to each performance obligation based on its relative standalone selling price, which is determined based on our overall pricing objectives, taking into consideration market conditions and other factors.

Revenue is recognized when control of the goods and services provided are transferred to our customers and in an amount that reflects the consideration we expect to be entitled to in exchange for those goods and services using the following steps: 1) identify the contract, 2) identify the performance obligations, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue as or when we satisfy the performance obligations.

We generate our revenues under four types of billing arrangements: fixed-fee (including software license revenue); time-and-expense; performance-based; and software support, maintenance and subscriptions.

•Fixed-fee (including software license revenue): In fixed-fee billing arrangements, we agree to a pre-established fee in exchange for a predetermined set of professional services. We set the fees based on our estimates of the costs and timing for completing the engagements. We generally recognize revenues under fixed-fee billing arrangements using a proportionate performance approach, which is based on work completed to date versus our estimates of the total services to be provided under the engagement. Contracts within our culture and organizational excellence solution include fixed-fee partner contracts with multiple performance obligations, which primarily consist of coaching services, as well as speaking engagements, conferences, publications and software products (“Partner Contracts”). Revenues for coaching services and software products are generally recognized on a straight-line basis over the length of the contract. All other revenues under Partner Contracts, including speaking engagements, conferences and publications, are recognized at the time the goods or services are provided. Estimates of total engagement revenues and cost of services are monitored regularly during the term of the engagement.

We also generate revenues from software licenses for our revenue cycle management software and research administration and compliance software. Licenses for our revenue cycle management software are sold only as a component of our consulting projects, and the services we provide are essential to the functionality of the software. Therefore, revenues from these software licenses are recognized over the term of the related consulting services contract. License revenue from our research administration and compliance software is generally recognized in the month in which the software is delivered.

•Time-and-expense: Under time-and-expense billing arrangements, we invoice our clients based on the number of hours worked by our revenue-generating professionals at agreed upon rates. Time-and-expense arrangements also include certain speaking engagements, conferences, and publications purchased by our clients outside of Partner Contracts within our culture and organizational excellence solution and the portion of our Healthcare managed services contracts that are billed under time-and-expense arrangements. We recognize revenues under time-and-expense arrangements as the related services or publications are provided, using the right to invoice practical expedient which allows us to recognize revenue in the amount that we have a right to invoice based on the number of hours worked and the agreed upon hourly rates or the value of the speaking engagements, conferences or publications purchased by our clients.

•Performance-based: In performance-based billing arrangements, fees are tied to the attainment of contractually defined objectives. We enter into performance-based engagements in essentially two forms. First, we generally earn fees that are directly related to the savings formally acknowledged by the client as a result of adopting our recommendations for improving operational and cost effectiveness in the areas we review. Second, we earn a success fee when and if certain predefined outcomes occur. We recognize revenue under performance-based billing arrangements using the following steps: 1) estimate variable consideration using a probability-weighted assessment of the fees to be earned, 2) apply a constraint to the estimated variable consideration to limit the amount that could be reversed when the uncertainty is resolved (the “constraint”), and 3) recognize revenue of estimated variable consideration, net of the constraint, based on work completed to date versus our estimates of the total services to be provided under the engagement.

•Software support, maintenance and subscriptions: Clients that have purchased one of our software licenses can pay an annual fee for software support and maintenance. We also generate subscription revenue from our cloud-based analytic tools and solutions. Software support, maintenance and subscription revenues are recognized ratably over the support or subscription period. These fees are generally billed in advance and included in deferred revenues until recognized.

Provisions are recorded for the estimated realization adjustments on all engagements, including engagements for which fees are subject to review by the bankruptcy courts.

Reimbursable expenses that are billed to clients, primarily relating to travel and out-of-pocket expenses incurred in connection with client engagements, are included in total revenues and reimbursable expenses. Reimbursable expenses are recognized as expenses in the period in which the expense is incurred.

The payment terms and conditions in our customer contracts vary. Differences between the timing of billings and the recognition of revenue are recognized as either unbilled services or deferred revenues in the consolidated balance sheets. Revenues recognized for services performed but not yet billed to clients are recorded as unbilled services. Revenues recognized, but for which we are not yet entitled to bill because certain events, such as the completion of the measurement period or client approval, must occur, are recorded as contract assets and included within unbilled services. Client prepayments and retainers are classified as deferred revenues and recognized over future periods as earned in accordance with the applicable engagement agreement.

Commissions Expense, Policy [Policy Text Block]

Capitalized Sales Commissions

Sales commissions earned by our sales professionals are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions with an expected amortization period greater than one year are deferred and amortized on a straight-line basis over the period of the associated contract. We elected to apply the practical expedient to expense sales commissions as incurred when the expected amortization period is one year or less. Amortization expense is recorded to direct costs.

Allowances for Doubtful Accounts and Unbilled Services

We maintain allowances for doubtful accounts and unbilled services based on several factors, including the estimated cash realization from amounts due from clients, an assessment of a client’s ability to make required payments, and the historical percentages of fee adjustments and write-offs by age of receivables and unbilled services. The allowances are assessed by management on a regular basis. These

estimates may differ from actual results. If the financial condition of a client deteriorates in the future, impacting the client’s ability to make payments, an increase to our allowance might be required or our allowance may not be sufficient to cover actual write-offs.

We record the provision for doubtful accounts and unbilled services as a reduction in revenue. To the extent we write-off accounts receivable due to a client's inability to pay, the charge is recognized as a component of selling, general and administrative expenses.

Direct Costs and Reimbursable Expenses

Direct Costs

Direct costs primarily consist of payroll costs for our revenue-generating professionals which includes salaries, performance bonuses, share-based compensation, signing and retention bonuses, payroll taxes and benefits. Direct costs also include fees paid to independent contractors that we retain to supplement our revenue-generating professionals, typically on an as-needed basis for specific client engagements, as well as technology costs, product and event costs, and commissions. Direct costs exclude amortization of intangible assets and software development costs and reimbursable expenses, both of which are separately presented in our consolidated statements of operations. Direct costs are expensed in the period incurred.

Cash and Cash Equivalents

We consider all highly liquid investments, including overnight investments and commercial paper, with original maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

To the extent receivables from clients become delinquent, collection activities commence. No single client balance is considered large enough to pose a material credit risk. The allowances for doubtful accounts and unbilled services are based upon the expected ability to collect accounts receivable and bill and collect unbilled services. Management does not anticipate incurring losses on accounts receivable in excess of established allowances. See Note 19 “Segment Information” for concentration of accounts receivable and unbilled services.

We hold our cash in accounts at multiple third-party financial institutions. These deposits, at times, may exceed federally insured limits. We review the credit ratings of these financial institutions, regularly monitor the cash balances in these accounts, and adjust the balances as appropriate. However, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets.

Investments

Long-term Investments

Our long-term investments consist of our convertible debt investment in Shorelight Holdings, LLC (“Shorelight”) and preferred stock investment in a hospital-at-home company.

We classified the convertible debt investment in Shorelight as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. The investment is carried at fair value with unrealized holding gains and losses reported in other comprehensive income. If the investment is in an unrealized loss position due to significant credit deterioration of the investee, we recognize an allowance to decrease the carrying value of the investment to the fair value, which may be reversed in the event that the credit of an issuer improves. In the event there are realized gains and losses or credit allowances recognized, we will record the amount in earnings. We have not realized any gains or losses or recognized any credit allowance on our convertible debt investment as of December 31, 2023. See Note 13 “Fair Value of Financial Instruments” for additional information on our convertible debt investment.

We classified the preferred stock investment in the hospital-at-home company as an equity security without a readily determinable value at the time of purchase and reevaluate such classification as of each balance sheet date. We elected to apply the measurement alternative at the time of purchase and will continue to do so until the investment does not qualify to be so measured. Under the measurement alternative, the investment is carried at cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment in the company. On a quarterly basis, we review the information available to determine whether an orderly and observable transaction for the same or similar equity instrument occurred or if factors indicate that a significant decrease in value has occurred. We remeasure to the fair value of the preferred stock using such identified information with changes in the fair value recorded in our consolidated statement of operations.

Property and Equipment

Property and equipment is recorded at cost, less accumulated depreciation, and depreciated using the straight-line method over the shorter of the estimated useful life of the asset or the lease term. Software, computers, and related equipment are depreciated over an estimated useful life of two to four years. Furniture and fixtures are depreciated over five years. Leasehold improvements are amortized over the lesser of the estimated useful life of the asset or the initial term of the lease.

Deferred Lease Incentives

Leases

We determine if an arrangement contains a lease and the classification of such lease at inception. As of December 31, 2023 and 2022, all of our material leases are classified as operating leases; we have not entered into any material finance leases. For all operating leases with an initial term greater than 12 months, we recognize an operating lease right-of-use (“ROU”) asset and operating lease liability. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.

Operating lease ROU assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date and provided by the administrative agent for our senior secured credit facility in determining the present value of lease payments. Operating lease ROU assets exclude lease incentives. We elected the practical expedient to combine lease and nonlease components. Certain lease agreements contain variable lease payments that do not depend on an index or rate. These variable lease payments are not included in the calculation of the operating lease ROU asset and operating lease liability; instead, they are expensed as incurred. Our leases may contain options to extend or terminate the lease, and we include these terms in our calculation of the operating lease ROU asset and operating lease liability when it is reasonably certain that we will exercise the option.

Operating lease expense is recognized on a straight-line basis over the lease term and recorded within selling, general and administrative expenses on our consolidated statement of operations. In accordance with our accounting policy for impairment of long-lived assets, operating lease ROU assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group to which the operating lease ROU asset is assigned may not be recoverable. We evaluate the recoverability of the asset group based on forecasted undiscounted cash flows.

Software Development Costs

We incur internal and external software development costs related to our cloud computing applications and software for internal use. We capitalize these software development costs incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Once the project is substantially complete and ready for its intended use, these costs are amortized on a straight-line basis over the technology's estimated useful life. Acquired technology assets are initially recorded at fair value and amortized on a straight-line basis over the estimated useful life.

Development costs related to software products that will be sold, leased, or otherwise marketed are expensed until technological feasibility has been established. Thereafter, and until the software is available for general release to customers, these software development costs are capitalized and subsequently reported at the lower of unamortized cost or net realizable value. These capitalized development costs are amortized in proportion to current and future revenue for each product with an annual minimum equal to the straight-line amortization over the remaining estimated economic life of the product. We did not capitalize any material development costs for this type of software during 2023 or 2022.

We classify capitalized software development costs, which primarily relate to cloud computing applications and software for internal use, as other non-current assets on our consolidated balance sheet. As of December 31, 2023, gross capitalized software development costs and related accumulated amortization was $72.3 million and $26.8 million, respectively. As of December 31, 2022, gross capitalized software development costs and related accumulated amortization was $47.7 million and $21.5 million, respectively. During the years ended December 31, 2023, 2022, and 2021, we amortized $6.5 million, $5.9 million, and $5.2 million, respectively, of capitalized software development costs. Additionally, in 2023, we recognized a $0.3 million restructuring charge for the abandonment of a capitalized software development project.

Implementation Costs Incurred in a Cloud Computing Arrangement

We incur costs to implement cloud computing arrangements that are service contracts. We capitalize certain costs associated with the implementation of the cloud computing arrangements, including employee payroll and related benefits and third party consulting costs, incurred during the application development stage of a project. These costs are amortized on a straight-line basis over the term of the hosting service contracts, including renewal periods we are reasonably certain to exercise, and recognized as a component of selling, general and administrative expenses on our consolidated statement of operations. As of December 31, 2023, gross capitalized implementation costs incurred in a cloud computing arrangement and related accumulated amortization was $7.2 million and $2.2 million, respectively. As of December 31, 2022, gross capitalized implementation costs incurred in a cloud computing arrangement and related accumulated amortization was $6.5 million and $1.5 million, respectively. During the years ended December 31, 2023, 2022 and 2021 we recognized amortization of our capitalized implementation costs of $0.7 million, $1.2 million and $0.9 million, respectively. Of the $1.2 million amortization for capitalized implementation costs in 2022, $0.3 million was recognized as a restructuring charge as it related to accelerated amortization of capitalized software implementation costs for a cloud-computing arrangement that is no longer in use. Our capitalized implementation costs primarily relate to the implementation of a new ERP system. In January 2021, we successfully went live with the new ERP system, and we continue to progress with additional functionality and integrations as scheduled. These capitalized costs are included as a component of prepaid expenses and other current assets and other non-current assets on our consolidated balance sheet.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

Intangible Assets Other Than Goodwill

Identifiable intangible assets are amortized over their expected useful lives using a method that reflects the economic benefit expected to be derived from the assets or on a straight-line basis. We evaluate the recoverability of intangible assets periodically by considering events or circumstances that may warrant revised estimates of useful lives or that indicate the asset may be impaired.

Impairment of Long-Lived Assets

Long-lived assets, including property and equipment, right-of-use assets, and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Events relating to recoverability may include significant unfavorable changes in business conditions, recurring losses, or a significant decline in forecasted operating results over an extended period of time. We evaluate the recoverability of long-lived assets based on forecasted undiscounted cash flows.

Goodwill

For acquisitions accounted for as a business combination, goodwill represents the excess of the cost over the fair value of the net assets acquired. We are required to test goodwill for impairment, at the reporting unit level, annually and when events or circumstances indicate the fair value of a reporting unit may be below its carrying value. We perform our annual goodwill impairment test as of November 30 and monitor for interim triggering events on an ongoing basis. A reporting unit is an operating segment or one level below an operating segment (referred to as a component) to which goodwill is assigned when initially recorded. We assign goodwill to reporting units based on our integration plans and the expected synergies resulting from the acquisition. As of December 31, 2023, we have three reporting units: Healthcare, Education, and Commercial.

Business Combinations

We use the acquisition method of accounting for business combinations. Each acquired company’s operating results are included in our consolidated financial statements starting on the date of acquisition. The purchase price is equivalent to the fair value of consideration transferred. The contract assets and contract liabilities acquired are recorded at their carrying value under Topic 606: Revenue from Contracts with Customers. All other tangible assets and identifiable intangible assets acquired and liabilities assumed are recorded at fair value as of the acquisition date. Goodwill is recognized for the excess of purchase price over the net value of tangible and intangible assets acquired and liabilities assumed. Contingent consideration, which is primarily based on the business achieving certain performance targets, is recognized at its fair value on the acquisition date, and changes in fair value are recognized in earnings until settled.

Income Taxes

Current tax liabilities and assets are recognized for the estimated taxes payable or refundable, respectively, on the tax returns for the current year. We have elected to recognize the tax expense related to Global Intangible Low-Taxed Income (“GILTI”) as a current period expense when incurred. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. To the extent that deferred tax assets will not likely be recovered from future taxable income, a valuation allowance is established against such deferred tax assets.

Share-Based Compensation

Share-based compensation cost is measured based on the grant date fair value of the respective awards. We generally recognize share-based compensation ratably using the straight-line attribution method; however, for those awards with performance criteria and graded vesting features, we use the graded vesting attribution method. It is our policy to account for forfeitures as they occur. Refer to Note 16 “Equity Incentive Plan” for further information regarding share-based compensation.

Sponsorship and Advertising Costs

Sponsorship and advertising costs are expensed as incurred.

Debt Issuance Costs

We amortize the costs we incur to obtain debt financing over the contractual life of the related debt using the straight-line method. The amortization expense is included in interest expense, net of interest income in our statement of operations. Unamortized debt issuance costs attributable to our senior secured revolving credit facility are included as a component of other non-current assets.

Foreign Currency

Assets and liabilities of foreign subsidiaries whose functional currency is not the United States Dollar (USD) are translated into USD using the exchange rates in effect at period end. Revenue and expense items are translated using the average exchange rates for the period. Foreign currency translation adjustments are included in accumulated other comprehensive income, which is a component of stockholders’ equity.

Foreign currency transaction gains and losses are included in other income, net on the consolidated statement of operations.

Segment Reporting

Segments are defined as components of a company that engage in business activities from which they may earn revenues and incur expenses, and for which separate financial information is available and is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. As of December 31, 2023, our chief operating decision maker manages the business under three operating segments, which are our reportable segments: Healthcare, Education, and Commercial.

Debt Disclosure [Abstract]
Financing Arrangements	Financing Arrangements The Company has a $600 million five-year senior secured revolving credit facility, subject to the terms of a Third Amended and Restated Credit Agreement dated as of November 15, 2022 and amended by Amendment No. 1 (collectively, the “Amended Credit Agreement”) that becomes due and payable in full upon maturity on November 15, 2027. In February 2024, the Company entered into Amendment No. 2 (the “Second Amendment”) to the Amended Credit Agreement to establish a $275 million term loan as discussed below under “2024 Term Loan.” Prior to the Second Amendment, the Amended Credit Agreement provided the option to increase the revolving credit facility or establish term loan facilities in an aggregate amount up to $250 million, subject to customary conditions and the approval of any lender whose commitment would be increased, resulting in a maximum available principal amount under the Amended Credit Agreement of $850 million. The initial borrowings under the revolving credit facility were used to refinance borrowings outstanding under a prior credit agreement, and future revolving credit facility borrowings under the Amended Credit Agreement may be used for working capital, capital expenditures, share repurchases, permitted acquisitions, and other general corporate purposes. Fees and interest on borrowings under the revolving credit facility vary based on our Consolidated Leverage Ratio (as defined in the Amended Credit Agreement). At our option, these borrowings will bear interest at one, three or six month Term SOFR or an alternate base rate, in each case plus the applicable margin. The applicable margin will fluctuate between 1.125% per annum and 1.875% per annum, in the case of Term SOFR borrowings, or between 0.125% per annum and 0.875% per annum, in the case of base rate loans, based upon our Consolidated Leverage Ratio at such time. In April 2023, the Company and PNC Capital Markets, LLC, as Sustainability Structuring Agent, with the consent of the Required Lenders (as defined in the Amended Credit Agreement), entered into Amendment No. 1 to the Amended Credit Agreement (the “First Amendment”) to incorporate specified key performance indicators with respect to certain environmental, social and governance targets of the Company. Based upon the performance of the Company against those key performance indicators in each Reference Year (as defined in the First Amendment), certain adjustments to the otherwise applicable rates for interest, commitment fees and letter of credit fees will be made. These annual adjustments will not exceed an increase or decrease of 0.01% in the aggregate for all key performance indicators in the case of the commitment fee rate or an increase or decrease of 0.05% in the aggregate for all key performance indicators in the case of the Term SOFR borrowings, base rate borrowings or letter of credit fee rate. Amounts borrowed under the Amended Credit Agreement may be prepaid at any time without premium or penalty. We are required to prepay the amounts outstanding under the Amended Credit Agreement in certain circumstances, including upon an Event of Default (as defined in the Amended Credit Agreement). In addition, we have the right to permanently reduce or terminate the unused portion of the commitments provided under the Amended Credit Agreement at any time. The loans and obligations under the Amended Credit Agreement are secured pursuant to a Third Amended and Restated Security Agreement (the “Security Agreement”) and a Third Amended and Restated Pledge Agreement (the “Pledge Agreement”) with Bank of America, N.A. as collateral agent, pursuant to which the Company and the subsidiary guarantors grant Bank of America, N.A., for the ratable benefit of the lenders under the Amended Credit Agreement, a first-priority lien, subject to permitted liens, on substantially all of the personal property assets of the Company and the subsidiary guarantors, and a pledge of 100% of the stock or other equity interests in all domestic subsidiaries and 65% of the stock or other equity interests in each “material first-tier foreign subsidiary” (as defined in the Pledge Agreement) entitled to vote and 100% of the stock or other equity interests in each material first-tier foreign subsidiary not entitled to vote. The Amended Credit Agreement contains usual and customary representations and warranties; affirmative and negative covenants, which include limitations on liens, investments, additional indebtedness, and restricted payments; and two quarterly financial covenants as follows: (i) a maximum Consolidated Leverage Ratio (defined as the ratio of debt to consolidated EBITDA) of 3.75 to 1.00; however the maximum permitted Consolidated Leverage Ratio will increase to 4.25 to 1.00 upon the occurrence of a Qualified Acquisition (as defined in the Amended Credit Agreement), and (ii) a minimum Consolidated Interest Coverage Ratio (defined as the ratio of consolidated EBITDA to interest) of 3.00 to 1.00. Consolidated EBITDA for purposes of the financial covenants is calculated on a continuing operations basis and includes adjustments to add back non-cash goodwill impairment charges, share-based compensation costs, certain non-cash restructuring charges, pro forma historical EBITDA for businesses acquired, and other specified items in accordance with the Amended Credit Agreement. For purposes of the Consolidated Leverage Ratio total debt is on a gross basis and is not netted against our cash balances. At December 31, 2023, we were in compliance with these financial covenants with a Consolidated Leverage Ratio of 1.59 to 1.00 and a Consolidated Interest Coverage Ratio of 10.85 to 1.00. Borrowings outstanding under the revolving credit facility at December 31, 2023 totaled $324.0 million and are classified as long-term debt in our consolidated balance sheet. These borrowings carried a weighted average interest rate of 4.2%, including the effect of the interest rate swaps described in Note 12 “Derivative Instruments and Hedging Activity.” Borrowings outstanding under the revolving credit facility at December 31, 2022 were $290.0 million and carried a weighted average interest rate of 3.8%, including the effect of the interest rate swaps in effect at that time. The borrowing capacity under the Amended Credit Agreement is reduced by any outstanding borrowings under the agreement and outstanding letters of credit. At December 31, 2023, we had outstanding letters of credit totaling $0.5 million, which are used as security deposits for our office facilities. As of December 31, 2023, the unused borrowing capacity under the Amended Credit Agreement was $275.5 million. 2024 Term Loan In February 2024, the Company entered into Amendment No.2 to the Amended Credit Agreement (the “Second Amendment”), which established a $275 million term loan facility (the “Term Loan”) under the Amended Credit Agreement (as amended to date, the “Current Credit Agreement”). The Term Loan is subject to scheduled quarterly amortization payments of $3.4 million beginning June 30, 2024 through the maturity date of November 15, 2027, at which time the outstanding principal balance and all accrued interest will be due. Additionally, the Second Amendment provided for the option to increase the revolving credit facility or establish additional term loan facilities in an aggregate amount up to $250 million, subject to customary conditions and the approval of any lender whose commitment would be increased, resulting in a maximum available principal amount under the Current Credit Agreement of $1.13 billion. The proceeds of the Term Loan will be used to reduce borrowings under the Company's revolving credit facility. Interest on the Term Loan varies based on our Consolidated Leverage Ratio (as defined in the Current Credit Agreement). At our option, the Term Loan will bear interest at one, three or six month Term SOFR plus the applicable margin. The applicable margin will range between 1.625% per annum and 2.375% per annum based upon our Consolidated Leverage Ratio at such time and subject to the adjustments allowed for performance against certain environmental, social and governance targets of the Company as outlined in the First Amendment. The Current Credit Agreement maintains the same prepayment provisions, usual and customary representations and warranties, fee pricing schedule, and affirmative and negative covenants as the Amended Credit Agreement discussed above; and is secured pursuant to the Security Agreement and the Pledge Agreement discussed above.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Earnings Per Share

Dec. 31, 2023

Earnings Per Share [Abstract]

Earnings Per Share

Basic earnings per share excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period, excluding unvested restricted common stock. Diluted earnings per share reflects the potential reduction in earnings per share that could occur if securities or other contracts to issue common stock were exercised or converted into common stock under the treasury stock method. Such securities or other contracts include unvested restricted stock awards, unvested restricted stock units, and outstanding common stock options, to the extent dilutive. In periods for which we report a net loss from continuing operations, diluted weighted average common shares outstanding excludes all potential common stock equivalents as their impact on diluted net loss per share would be anti-dilutive.

Earnings per share under the basic and diluted computations are as follows:


	Year Ended December 31,
	2023		2022		2021


Net income	$	62,479	$	75,552	$	62,987

Weighted average common shares outstanding—basic	18,832		20,249		21,439
Weighted average common stock equivalents	769		497		370
Weighted average common shares outstanding—diluted	19,601		20,746		21,809




Net income per basic share	$	3.32	$	3.73	$	2.94




Net income per diluted share	$	3.19	$	3.64	$	2.89

The number of anti-dilutive securities excluded from the computation of the weighted average common stock equivalents presented above at December 31, 2023, 2022 and 2021 was 0.1 million, 0.2 million and 0.1 million, respectively, and related to unvested restricted stock and outstanding common stock options.

Share Repurchase Program

In November 2020, our board of directors authorized a share repurchase program permitting us to repurchase up to $50 million of our common stock through December 31, 2021. The share repurchase program has been subsequently extended and increased, most recently in the fourth quarter of 2023. The current authorization extends the share repurchase program through December 31, 2024 with a repurchase amount of $400 million. The amount and timing of repurchases under the share repurchase program were and will continue to be determined by management and depend on a variety of factors, including the trading price of our common stock, capacity under our credit facility, general market and business conditions, and applicable legal requirements.

During 2023, we repurchased and retired 1,461,815 shares for $123.6 million, including 10,000 shares for $1.0 million which settled in the first quarter of 2024. Additionally, during 2023, we settled the repurchase of 15,200 shares for $1.1 million that were accrued as of December 31, 2022 and accrued $0.9 million of excise taxes on the net share repurchases in 2023.

During 2022, we repurchased and retired 2,037,752 shares for $121.3 million, including the 15,200 shares for $1.1 million which settled in the first quarter of 2023. Additionally, during 2022, we settled the repurchase of 3,820 shares for $0.2 million that were accrued as of December 31, 2021. During 2021, we repurchased and retired 1,265,261 shares for $64.8 million, including 3,820 shares for $0.2 million which settled in the first quarter of 2022.

As of December 31, 2023, $86.2 million remained available for share repurchases under our share repurchase program.

Segment Information

Segment Reporting [Abstract]

Segment Information

Segments are defined as components of a company that engage in business activities from which they may earn revenues and incur expenses, and for which separate financial information is available and is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker, who is our chief executive officer, manages the business under three operating segments, which are our reportable segments: Healthcare, Education, and Commercial.

•Healthcare

Our Healthcare segment serves acute care providers, including national and regional health systems; academic health systems; community health systems; the federal health system; and public, children’s and critical access hospitals, and non-acute care providers, including physician practices and medical groups; payors; and long-term care or post-acute providers. Our healthcare-focused services and products include financial and operational performance improvement consulting, which spans revenue cycle, cost and care delivery transformation; digital offerings, spanning technology and analytic-related services, including enterprise health record (“EHR”), ERP and enterprise performance management (“EPM”), customer relationship management (“CRM”), data management and technology managed services, and a portfolio of software products; organizational transformation; revenue cycle managed services and outsourcing; financial and capital advisory consulting; and strategy and innovation consulting.

•Education

Our Education segment serves public and private colleges and universities, research institutes and other education-related organizations. Our education and research-focused services and products include our digital offerings, spanning technology and analytic-related services, including student information systems, ERP and EPM, CRM, data management and technology managed services and our Huron Research Suite product suite (the leading software suite designed to facilitate and improve research administration service delivery and compliance); our research-focused consulting and managed services; and our strategy and operations consulting services, which span finance and accounting and operations to organization and talent strategy and student and academic strategy.

•Commercial

Our Commercial segment is focused on serving industries and organizations facing significant disruption and regulatory change by helping them adapt to rapidly changing environments and accelerate business transformation. Our Commercial professionals work primarily with six primary buyers: the chief executive officer, the chief financial officer, the chief strategy officer, the chief human resources officer, the chief operating officer, and organizational advisors, including lenders and law firms. We have a deep focus on serving organizations in the financial services, energy and utilities, industrials and manufacturing industries and the public sector while opportunistically serving commercial industries more broadly, including professional and business services, life sciences, consumer products, and nonprofit. Our Commercial professionals use their deep industry, functional and technical expertise to deliver our digital services and software products, financial advisory (special situation advisory and corporate finance advisory) services, and strategy and innovation consulting services.

Segment operating income consists of the revenues generated by a segment, less operating expenses that are incurred directly by the segment. Unallocated costs include corporate costs related to administrative functions that are performed in a centralized manner that are not attributable to a particular segment. These administrative function costs include corporate office support costs, office facility costs, costs related to accounting and finance, human resources, legal, marketing, information technology, and company-wide business development functions, as well as costs related to overall corporate management. Our chief operating decision maker does not evaluate segments using asset information.

Postemployment Benefits [Abstract]
Employee Benefit and Deferred Compensation Plans	Employee Benefit and Deferred Compensation Plans We sponsor a qualified defined contribution 401(k) plan covering substantially all of our employees. Under the plan, employees are entitled to make pretax, post-tax, and/or Roth post-tax contributions up to the annual maximums established by the Internal Revenue Service. We match an amount equal to the employees’ contributions up to 6% of the employees’ eligible earnings. Our matching contributions for the years ended December 31, 2023, 2022, and 2021 were $37.0 million, $31.2 million, and $29.9 million, respectively. We have a non-qualified deferred compensation plan (the “Plan”) that is administered by our board of directors or a committee designated by the board of directors. Under the Plan, members of the board of directors and a select group of our employees may elect to defer the receipt of their director retainers and meeting fees or base salary and bonus, as applicable. Additionally, we may credit amounts to a participant’s deferred compensation account in accordance with employment or other agreements entered into between us and the participant. At our sole discretion, we may, but are not required to, credit any additional amount we desire to any participant’s deferred compensation account. Amounts credited are subject to vesting schedules set forth in the Plan, employment agreement, or any other agreement entered into between us and the participant. The deferred compensation liability at December 31, 2023 and 2022 was $34.7 million and $29.9 million, respectively. This deferred compensation liability is fully funded by the Plan assets.

Leases [Abstract]

Lessee, Operating Leases

Leases

We lease office space, data centers and certain equipment under operating leases expiring on various dates through 2030, with various renewal options that can extend the lease terms by one to ten years. Our operating leases include fixed payments plus, in some cases, scheduled base rent increases over the term of the lease. Certain leases require variable payments of real estate taxes, insurance and operating expenses. We exclude these variable payments from the measurements of our lease liabilities and expense them as incurred. We elected the practical expedient to combine lease and nonlease components. No lease agreements contain any residual value guarantees or material restrictive covenants. As of December 31, 2023, we have not entered into any material finance leases. We sublease certain office spaces to third parties resulting from restructuring activities in certain locations.

Lease Impairment Charges

Operating lease right-of-use (“ROU”) assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group to which the operating lease ROU asset is assigned may not be recoverable. First, we test the asset group for recoverability by comparing the undiscounted cash flows of the asset group, which include expected future lease and nonlease payments related to the lease agreement offset by expected sublease income, to the carrying amount of the asset group. If the first step of the long-lived asset impairment test concludes that the carrying amount of the asset group is not recoverable, we perform the second step of the long-lived asset impairment test by comparing the fair value of the asset group to its carrying amount and recognizing a lease impairment charge for the amount by which the carrying amount exceeds the fair value. To estimate the fair value of the asset group, we rely on a discounted cash flow approach using market participant assumptions of the expected cash flows and discount rate.

During the years ended December 31, 2023 and 2022, we recognized non-cash lease-related impairment charges of $6.3 million and $0.2 million, respectively. No lease-related impairment charges were recognized during 2021.

2023

During 2023, we exited our office spaces in Hillsboro, Oregon and Lexington, Massachusetts, resulting in non-cash impairment charges of $5.4 million, of which $4.0 million was allocated to the operating lease ROU assets and $1.4 million was allocated to the related fixed assets based on their relative carrying amounts. Additionally, in 2023, we recognized $0.9 million of lease-related impairment charges driven by updated sublease assumptions for our previously vacated office spaces in Hillsboro, Oregon; New York, New York; and Lake Oswego, Oregon. Of the $0.9 million, $0.5 million was allocated to the fixed assets related to the office spaces and $0.4 million was allocated to the operating lease ROU assets based on their relative carrying amounts.

2022

The $0.2 million lease-related impairment charge recognized in 2022 resulted from updated sublease assumptions for our previously vacated office space in New York City, New York and was allocated to the operating lease ROU asset.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Certain of our assets and liabilities are measured at fair value. Fair value is defined as the price that would be received to sell an asset or the price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy for inputs used in measuring fair value and requires companies to maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy consists of three levels based on the objectivity of the inputs as follows:


Level 1 Inputs						Quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs						Quoted prices in active markets for similar assets or liabilities; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 Inputs						Unobservable inputs for the asset or liability, and include situations in which there is little, if any, market activity for the asset or liability.

The tables below sets forth our fair value hierarchy for our financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2023 and 2022.

Interest rate swaps: The fair values of our interest rate swaps were derived using estimates to settle the interest rate swap agreements, which are based on the net present value of expected future cash flows on each leg of the swaps utilizing market-based inputs and a discount rate reflecting the risks involved. See Note 12 “Derivative Instruments and Hedging Activity” for additional information on our interest rate swaps.

Foreign exchange forward contracts: The fair values of our foreign exchange forward contracts were derived using estimates to settle the foreign exchange forward contracts agreements, which are based on the net present value of expected future cash flows on each contract utilizing market-based inputs, including both forward and spot prices, and a discount rate reflecting the risks involved. Refer to Note 12 “Derivative Instruments and Hedging Activity” for additional information on our foreign exchange forward contracts.

Deferred compensation assets: We have a non-qualified deferred compensation plan (the “Plan”) for the members of our board of directors and a select group of our employees. The deferred compensation liability is funded by the Plan assets, which consist of life insurance policies maintained within a trust. The cash surrender value of the life insurance policies approximates fair value and is based on third-party broker statements which provide the fair value of the life insurance policies' underlying investments, which are Level 2 inputs. The cash surrender value of the life insurance policies is invested primarily in mutual funds. The Plan assets are included in other non-current assets in our consolidated balance sheets. Realized and unrealized gains (losses) from the deferred compensation assets are recorded to other income (expense), net in our consolidated statements of operations.

Convertible debt investment: Since 2014, we have invested $40.9 million, in the form of 1.69% convertible debt in Shorelight Holdings, LLC (“Shorelight”), the parent company of Shorelight, a U.S.-based company that partners with leading nonprofit universities to increase access to and retention of international students, boost institutional growth, and enhance an institution’s global footprint. The convertible notes will mature on January 17, 2027, unless converted earlier.

To determine the appropriate accounting treatment for our investment, we performed a variable interest entity (“VIE”) analysis and concluded that Shorelight does not meet the definition of a VIE. We also reviewed the characteristics of our investment to confirm that the convertible notes are not in-substance common stock that would warrant equity method accounting. After we reviewed all of the terms of the investment, we concluded the appropriate accounting treatment to be that of an available-for-sale debt security. We continue to monitor the key factors of our VIE analysis and the terms of the convertible notes to ensure our accounting treatment is appropriate. We have not identified any changes to Shorelight or our investment, that would change our classification of the investment as an available-for-sale debt security.

The investment is carried at fair value with unrealized holding gains and losses excluded from earnings and reported in other comprehensive income. The carrying value is recorded in long-term investments in our consolidated balance sheets. We estimate the fair value of our investment using a scenario-based approach in the form of a hybrid analysis that consists of a Monte Carlo simulation model and an expected return analysis. The conclusion of value for our investment is based on the probability-weighted assessment of both scenarios. The hybrid analysis utilizes certain assumptions including the assumed holding period through the maturity date of January 17, 2027 for the valuations performed as of December 31, 2023 and 2022; the applicable waterfall distribution at the end of the expected holding period based on the rights and privileges of the various instruments; cash flow projections discounted at the risk-adjusted rate of 24.5% and 24.0% as of December 31, 2023 and 2022, respectively; and the concluded equity volatility of 35.0% and 40.0% as of December 31, 2023 and 2022, all of which are Level 3 inputs. The use of alternative estimates and assumptions could increase or decrease the estimated fair value of the investment, which would result in different impacts to our consolidated balance sheet and comprehensive income. Actual results may differ from our estimates.

The table below sets forth the changes in the balance of the convertible debt investment for the years ended December 31, 2023 and 2022.


	Convertible Debt Investment
Balance as of December 31, 2021	$	65,918

Change in fair value of convertible debt investment	(8,355)
Balance as of December 31, 2022	57,563

Change in fair value of convertible debt investment	10,483
Balance as of December 31, 2023	$	68,046

Contingent consideration for business acquisitions: We estimate the fair value of acquisition-related contingent consideration using either a probability-weighted assessment of the specific financial performance targets being measured or a Monte Carlo simulation model, as appropriate. These fair value measurements are based on significant inputs not observable in the market and thus represent Level 3 inputs. The significant unobservable inputs used in the fair value measurements of our contingent consideration are our measures of the estimated payouts based on internally generated financial projections on a probability-weighted basis and a discount rate which was 6.3% as of December 31, 2023 and 5.5% as of December 31, 2022. The fair value of the contingent consideration is reassessed quarterly based on assumptions used in our latest projections and input provided by practice leaders and management. Any change in the fair value estimate is recorded in our consolidated statement of operations for that period. The use of alternative estimates and assumptions could increase or decrease the estimated fair value of our contingent consideration liability, which would result in different impacts to our consolidated balance sheets and consolidated statements of operations. Actual results may differ from our estimates.

The table below sets forth the changes in the balance of the contingent consideration for business acquisitions for the years ended December 31, 2023 and 2022.


	Contingent Consideration for Business Acquisitions
Balance as of December 31, 2021	$	3,743

Financial assets and liabilities not recorded at fair value on a recurring basis are as follows:

Preferred Stock Investment

In the fourth quarter of 2019, we invested $5.0 million in a hospital-at-home company. The investment was made in the form of preferred stock. To determine the appropriate accounting treatment for our preferred stock investment, we performed a VIE analysis and concluded that the company does not meet the definition of a VIE. We also reviewed the characteristics of our investment to confirm that the preferred stock is not in-substance common stock that would warrant equity method accounting. After we reviewed all of the terms of the investment, we concluded the appropriate accounting treatment for our investment to be that of an equity security with no readily determinable fair value. We elected to apply the measurement alternative at the time of the purchase and will continue to do so until the investment does not qualify to be so measured. Under the measurement alternative, the investment is carried at cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment in the same company. On a quarterly basis, we review the information available to determine whether an orderly and observable transaction for the same or similar equity instrument occurred or if factors indicate that a significant decrease in value has occurred. We remeasure to the fair value of the preferred stock using such identified information with changes in the fair value recorded in our consolidated statement of operations.

In the fourth quarter of 2023, we recognized a non-cash impairment loss of $26.3 million on our preferred stock investment based on the valuation established in a new round of financing expected to close in early 2024. During the first quarter of 2022, we recognized a non-cash unrealized gain of $27.0 million, based on the observable price change of preferred stock issued by the company with similar rights and preferences to our preferred stock investment, a Level 2 input. The non-cash impairment loss and unrealized gain were recorded to other income (expense), net in our consolidated statement of operations. There were no observable price changes in 2023 or 2021. Since our initial investment, we have recognized cumulative unrealized gains of $28.6 million and cumulative unrealized losses of $26.3 million. As of December 31, 2023 and 2022, the carrying value of our preferred stock investment was $7.4 million and $33.6 million, respectively.

Senior Secured Credit Facility

The carrying value of our borrowings outstanding under our senior secured credit facility is stated at cost. Our carrying value approximates fair value, using Level 2 inputs, as the senior secured credit facility bears interest at variable rates based on current market rates as set forth in the Amended Credit Agreement. Refer to Note 7 “Financing Arrangements” for additional information on our senior secured credit facility.

Cash and Cash Equivalents and Other Financial Instruments

Cash and cash equivalents are stated at cost, which approximates fair market value. The carrying values of all other financial instruments not described above reasonably approximate fair market value due to the nature of the financial instruments and the short-term maturity of these items.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	. Revenues For the years ended December 31, 2023, 2022 and 2021 we recognized revenues of $1.36 billion, $1.13 billion, and $905.6 million, respectively. Of the $1.36 billion recognized in 2023, we recognized revenues of $10.9 million from obligations satisfied, or partially satisfied, in prior periods, of which $9.6 million was primarily due to changes in the estimates of our variable consideration under performance-based billing arrangements and $1.3 million was primarily due to the release of allowances on receivables from clients and unbilled services. Of the $1.13 billion recognized in 2022, we recognized revenues of $7.6 million from obligations satisfied, or partially satisfied, in prior periods, of which $5.3 million was primarily due to changes in the estimates of our variable consideration under performance-based billing arrangements and $2.3 million was primarily due to the release of allowances on receivables from clients and unbilled services. Of the $905.6 million recognized in 2021, we recognized revenues of $22.9 million from obligations satisfied, or partially satisfied, in prior periods, of which $14.6 million was primarily due to changes in the estimates of our variable consideration under performance-based billing arrangements and $8.3 million was primarily due to the release of allowances on receivables from clients and unbilled services. As of December 31, 2023, we had $227.8 million of remaining performance obligations under engagements with original expected durations greater than one year. These remaining performance obligations exclude variable consideration which has been excluded from the total transaction price due to the constraint and performance obligations under time-and-expense engagements which are recognized in the amount invoiced. Of the $227.8 million of performance obligations, we expect to recognize approximately $82.7 million as revenue in 2024, $54.3 million in 2025, and the remaining $90.8 million thereafter. Actual revenue recognition could differ from these amounts as a result of changes in the estimated timing of work to be performed, adjustments to estimated variable consideration in performance-based arrangements, or other factors. Contract Assets and Liabilities The payment terms and conditions in our customer contracts vary. Differences between the timing of billings and the recognition of revenue are recognized as either unbilled services or deferred revenues in the consolidated balance sheets. Unbilled services include revenues recognized for services performed but not yet billed to clients. Services performed that we are not yet entitled to bill because certain events, such as the completion of the measurement period or client approval in performance-based engagements, must occur are recorded as contract assets and included within unbilled services, net. The contract asset balance, net as of December 31, 2023 and 2022 was $70.1 million and $50.2 million, respectively. The $19.9 million increase primarily reflects timing differences between the completion of our performance obligations and the amounts billed or billable to clients in accordance with their contractual billing terms. Client prepayments and retainers are classified as deferred revenues and recognized over future periods in accordance with the applicable engagement agreement and our revenue recognition accounting policy. Our deferred revenues balance as of December 31, 2023 and 2022 was $22.5 million and $21.9 million respectively. The $0.6 million increase primarily reflects timing differences between client payments in accordance with their contract terms and the completion of our performance obligations. For the year ended December 31, 2023, $21.3 million of revenues recognized were included in the deferred revenue balance as of December 31, 2022. For the year ended December 31, 2022, $18.5 million of revenues recognized were included in the deferred revenue balance as of December 31, 2021.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Income Tax Disclosure [Abstract]

Income Taxes

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law, which among other items, includes income tax provisions relating to net operating loss carryback period, options to defer payroll tax payments for a limited period and technical corrections to tax depreciation methods for qualified improvement property. As a result of electing the retroactive Global Intangible Low-Taxed Income (“GILTI”) high-tax exclusion in the second quarter of 2021, we recognized a $1.0 million tax benefit of which $0.4 million related to carrying back our increased 2018 federal net operating loss to prior year income for a refund at the higher, prior year tax rate. Additionally, during the third quarter of 2021, we recognized an additional tax benefit of $2.0 million, primarily related to the U.S. federal return to provision adjustments for carrying back our increased 2020 federal net operating loss to prior year income for a refund at the higher, prior year tax rate.

The income tax expense (benefit) for the years ended December 31, 2023, 2022, and 2021 consisted of the following:

As of both December 31, 2023 and 2022, we had valuation allowances of $5.7 million, primarily due to uncertainties relating to the ability to utilize deferred tax assets recorded for foreign losses and tax credits.

The Company has foreign net operating losses of $3.5 million which begin to expire in 2027 and state net operating loss carryforwards of $0.1 million which will begin to expire in 2040, if not utilized. We have federal tax credit carryforwards of $1.6 million which will begin to expire in 2030, if not utilized.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution.

A reconciliation of our beginning and ending amount of unrecognized tax benefits is as follows:


	Unrecognized Tax Benefits
Balance at January 1, 2021	$	744
Balance at December 31, 2021	744
Decrease due to lapse of statue of limitations	(101)
Decrease based on tax positions related to prior years	(50)
Balance at December 31, 2022	593
Decrease due to lapse of statue of limitations	(593)

Balance at December 31, 2023	$	—

As of December 31, 2022, we had $0.6 million of unrecognized tax benefits, which would affect the effective tax rate if recognized. There was no unrecognized tax benefit as of December 31, 2023.

As December 31, 2022, we had $0.1 million accrued for the potential payment of interest and penalties. No potential payment of interest and penalties was accrued as of December 31, 2023. Accrued interest and penalties are recorded as a component of provision for income taxes on our consolidated statement of earnings.

We file income tax returns with federal, state, local and foreign jurisdictions. Tax years 2020 through 2022 are subject to future examinations by federal tax authorities. Tax years 2017 through 2022 are subject to future examinations by state and local tax authorities. Our foreign income tax filings are subject to future examinations by the local foreign tax authorities for tax years 2018 through 2022. Currently, we are not under audit by any tax authority.

2023 Annual Goodwill Impairment Test

Pursuant to our policy, we performed our annual goodwill impairment test as of November 30, 2023 for our three reporting units: Healthcare, Education, and Commercial. We performed a qualitative assessment over all reporting units to determine if it was more likely than not the respective fair values of these reporting units were less than their carrying amounts, including goodwill.

For our qualitative assessment, we considered the most recent quantitative analysis performed for each reporting unit, which was as of January 1, 2022, including the key assumptions used within that analysis, the indicated fair values, and the amount by which those fair values exceeded their carrying amounts. One of the key assumptions used within the prior quantitative analysis was our internal financial projections; therefore, we considered the actual performance of each reporting unit during 2022 and 2023 compared to the internal financial projections used, as well as specific outlooks for each reporting unit based on our most recent internal financial projections. We also reviewed the current carrying value of each reporting unit in comparison to the carrying values as of the prior quantitative analysis. In addition, we considered various factors, including macroeconomic conditions, relevant industry and market trends for each reporting unit, and other entity-specific events, that could indicate a potential change in the fair value of our reporting units or the composition of their carrying values. Based on our assessments, we determined that it was more likely than not that the fair values for each of our reporting units exceeded their respective carrying amounts. As such, the goodwill for our reporting units was not considered impaired as of November 30, 2023, and a quantitative goodwill impairment analysis was not necessary.

Further, we evaluated whether any events have occurred or any circumstances have changed since November 30, 2023 that would indicate goodwill may have become impaired since our annual impairment test. Based on our evaluation as of December 31, 2023, we determined that no indications of impairment have arisen since our annual goodwill impairment test.

The results of an impairment analysis are as of a point in time. There is no assurance that the actual future earnings or cash flows of our reporting units will be consistent with our projections. We will monitor any changes to our assumptions and will evaluate goodwill as deemed warranted during future periods. Any significant decline in our operations could result in non-cash goodwill impairment charges.

First Quarter 2022 Goodwill Reallocation and Goodwill Impairment Test

Effective January 1, 2022, we modified our operating model to expand and more deeply integrate our industry expertise with our digital, strategic and financial advisory capabilities. To align with the new operating model, effective with reporting for periods beginning January 1, 2022, we began reporting under the following three industries, which are our reportable segments: Healthcare, Education and Commercial. The Commercial segment includes all industries outside of healthcare and education, including, but not limited to, financial services and energy and utilities. In the new reporting structure, each segment includes all revenue and costs associated with engagements delivered in the respective segments' industries. The new Healthcare and Education segments include some revenue and costs historically reported in the Business Advisory segment and the Healthcare segment includes some revenue and costs historically reported in the Education segment.

The three reportable segments of Healthcare, Education and Commercial are also our reporting units for goodwill impairment testing purposes. As a result of the reorganization, we reallocated the goodwill balances of our historical reporting units to our new reporting units based on the relative estimated fair values of each component of the historical reporting units to be allocated to the new reporting units. Additionally, we performed a goodwill impairment test on the goodwill balances of each of our reporting units as of January 1, 2022 by comparing the fair value of the reporting unit to its carrying value, including the reallocated goodwill. Based on the results of the goodwill impairment test, we determined the fair values of the Healthcare, Education, and Commercial reporting units exceeded their carrying values by 37%, 199%, and 105%, respectively. As such, we concluded that there was no indication of goodwill impairment for all three reporting units as of January 1, 2022.

We relied on the income approach to estimate the fair value of the reporting units for both the goodwill reallocation and the goodwill impairment test. The income approach utilized a discounted cash flow analysis, which involved estimating the expected after-tax cash flows that will be generated by each business and then discounting those cash flows to present value, reflecting the relevant risks associated with each reporting unit and the time value of money. This approach requires the use of significant estimates and assumptions, including forecasted revenue growth rates, forecasted EBITDA margins, and discount rates that reflect the risk inherent in the future cash flows. In estimating future cash flows, we relied on internally generated ten-year forecasts. Our forecasts are based on historical experience, current backlog, expected market demand, and other industry information.

Intangible Assets

Intangible assets as of December 31, 2023 and 2022 consisted of the following:


		As of December 31,
		2023				2022
	Useful Life in Years	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Customer relationships	5 to 10	$	60,636	$	48,928	$	74,583	$	57,219
Technology and software	2 to 5	16,230		10,195		13,330		7,975
Trade names	6	6,000		6,000		6,000		5,907
Non-competition agreements	4 to 5	720		389		920		340

Total		$	83,586	$	65,512	$	94,833	$	71,441

Identifiable intangible assets with finite lives are amortized over their estimated useful lives. Customer relationships and customer contracts, as well as certain trade names and technology and software, are amortized on an accelerated basis to correspond to the cash flows expected to be derived from the assets. All other intangible assets with finite lives are amortized on a straight-line basis.

Intangible assets amortization expense was $8.2 million, $11.2 million, and $9.3 million for the years ended December 31, 2023, 2022, and 2021, respectively. The table below sets forth the estimated annual amortization expense for each of the five succeeding years for the intangible assets recorded as of December 31, 2023.


Year Ending December 31,	Estimated Amortization Expense
2024	$	5,554
2025	$	4,344
2026	$	3,112
2027	$	2,127
2028	$	1,524

Actual future amortization expense could differ from these estimated amounts as a result of future acquisitions, dispositions, and other factors.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activity

In the normal course of business, we use forward interest rate swaps to manage the interest rate risk associated with our variable-rate borrowings under our senior secured credit facility and we use non-deliverable foreign exchange forward contracts to manage the foreign currency exchange rate risk related to our Indian Rupee-denominated expenses of our operations in India. From time to time, we may enter into additional forward interest rate swaps or non-deliverable foreign exchange forward contracts to further hedge against our interest rate risk and foreign currency exchange rate risk. We do not use derivative instruments for trading or other speculative purposes.

We have designated all of our derivative instruments as cash flow hedges. Therefore, changes in the fair value of the interest rate swaps and foreign exchange forward contracts are recorded to other comprehensive income to the extent effective and reclassified to earnings upon settlement.

Interest Rate Swaps

We are party to forward interest rate swap agreements with aggregate notional amounts of $250.0 million and $200.0 million as of December 31, 2023 and 2022, respectively. Under the terms of the interest rate swap agreements, we receive from the counterparty interest on the notional amount based on one month Term SOFR and we pay to the counterparty a stated, fixed rate. The forward interest rate swap agreements have staggered maturities through February 29, 2028.

As of December 31, 2023, it was anticipated that $5.2 million of the gains, net of tax, related to interest rate swaps currently recorded in accumulated other comprehensive income will be reclassified into earnings in our consolidated statement of operations within the next 12 months.

Foreign Exchange Forward Contracts

We are party to non-deliverable foreign exchange forward contracts that are scheduled to mature monthly through December 31, 2024. As of December 31, 2023 and 2022, the aggregate notional amounts of these contracts were INR 1,375.7 million, or $16.6 million, and INR 657.9 million, or $8.0 million, respectively, based on the exchange rates in effect as of each period end.

As of December 31, 2023, it was anticipated that all of the $0.1 million losses, net of tax, related to foreign exchange forward contracts currently recorded in accumulated other comprehensive income will be reclassified into earnings in our consolidated statement of operations within the next 12 months.

Earnings Per Share (Policies)	12 Months Ended
Earnings Per Share (Policies)	Dec. 31, 2023
Earnings Per Share [Abstract]
Earnings Per Share, Policy	Basic earnings per share excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period, excluding unvested restricted common stock. Diluted earnings per share reflects the potential reduction in earnings per share that could occur if securities or other contracts to issue common stock were exercised or converted into common stock under the treasury stock method. Such securities or other contracts include unvested restricted stock awards, unvested restricted stock units, and outstanding common stock options, to the extent dilutive. In periods for which we report a net loss from continuing operations, diluted weighted average common shares outstanding excludes all potential common stock equivalents as their impact on diluted net loss per share would be anti-dilutive.
