Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2021
Accounting Policies [Abstract]
Accounting Principles	Accounting Principles Our financial statements are prepared in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The consolidated financial statements include the accounts of FTI Consulting and all of our subsidiaries. All intercompany transactions and balances have been eliminated. Reclassifications of certain prior period amounts have been made to conform to the current period presentation.
Foreign Currency	Foreign Currency Results of operations for our non-U.S. subsidiaries are translated from the designated functional currency to the reporting currency of the U.S. dollar ("USD"). Revenues and expenses are translated at average exchange rates for each month, while assets and liabilities are translated at balance sheet date exchange rates. Resulting net translation adjustments are recorded as a component of stockholders’ equity in “Accumulated other comprehensive loss.” Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in “Interest income and other” on the Consolidated Statements of Comprehensive Income. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during the period or remains outstanding at the balance sheet date.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Due to the inherent uncertainty involved in making those assumptions, actual results could differ from those estimates. Our most significant estimates relate to revenues and the assessment of the recoverability of goodwill and intangible assets. Other estimates include, but are not limited to, the realization of deferred tax assets and the fair value of acquisition-related contingent consideration. Management bases its estimates on historical trends, projections, current experience and other assumptions that it believes are reasonable.
Concentrations of Risk	Concentrations of Risk We do not have a single customer that represents 10% or more of our consolidated revenues. We derive the majority of our revenues from providing professional services to clients in the U.S. For the year ended December 31, 2021, we derived approximately 38% of our consolidated revenues from the work of professionals who are assigned to locations outside the U.S. We believe that the geographic and industry diversity of our customer base throughout the U.S. and internationally minimizes the risk of incurring material losses due to concentrations of credit risk.
Revenues	Revenue Recognition Revenues are recognized when we satisfy a performance obligation by transferring services promised in a contract to a customer and in an amount that reflects the consideration that we expect to receive in exchange for those services. Performance obligations in our contracts represent distinct or separate services that we provide to our customers. If, at the outset of an arrangement, we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met. We generate the majority of our revenues by providing consulting services to our clients. Most of our consulting service contracts are based on one of the following types of contract arrangements: •Time and expense arrangements require the client to pay us based on the number of hours worked at contractually agreed-upon rates. We recognize revenues for these contract arrangements based on hours incurred and contracted rates utilizing a right-to-invoice practical expedient because we have a right to consideration for services completed to date. When a time and expense arrangement has a not-to-exceed or "cap" amount and we expect to perform work in excess of the cap, we recognize revenues up to the cap amount specified by the client, based on the efforts or hours incurred as a percentage of total efforts or hours expected to be incurred (i.e., proportional performance method). •Fixed-fee arrangements require the client to pay a fixed fee in exchange for a predetermined set of professional services. We recognize revenues earned to date by applying the proportional performance method. Generally, these arrangements have one performance obligation. •Performance-based or contingent arrangements represent forms of variable consideration. In these arrangements, our fees are based on the attainment of contractually defined objectives with our client, such as completing a business transaction or assisting the client in achieving a specific business objective. We recognize revenues earned to date in an amount that is probable not to reverse and by applying the proportional performance method when the criteria for over time revenue recognition are met. Certain fees in our time and materials arrangements may be subject to approval by a third party, such as a bankruptcy court and other regulatory agency. In such cases, we record revenues based on the amount we estimate we will be entitled to in exchange for our services and only to the extent a significant reversal of revenue is not likely to occur when the uncertainty associated with the estimate is subsequently resolved. Potential fee reductions imposed by bankruptcy courts and other regulatory agencies or negotiated with specific clients are estimated on a specific identification basis. Our estimates may vary depending on the nature of the engagement, client economics, historical experience and other appropriate factors. When there are changes in our estimates of potential fee reductions, we record such changes to revenues with a corresponding offset to our billed and unbilled accounts receivable. In our Technology segment, we generate unit-based revenues that are recognized at agreed-upon per unit rates for the amount of data stored or processed, the number of concurrent users accessing the information, or the number of pages or images processed for a client. Reimbursable expenses, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues, and an equivalent amount of reimbursable expenses is included in costs of services in the period in which the expense is incurred. Timing of revenue recognition often differs from the timing of billing to our customers. Generally, we transfer goods or services to a customer before the customer pays consideration or payment is due. If we have an unconditional right to invoice and receive payment for goods or services already provided, we record billed and unbilled receivables on our Consolidated Balance Sheets. Our contract terms generally include a requirement of payment within 30 days when no contingencies exist. Payment terms and conditions vary depending on the jurisdiction, market and type of service, and whether regulatory or other third-party approvals are required. At times, we may execute contracts in a form provided by customers that might include different payment terms and contracts may be negotiated at the client’s request. Direct Cost of Revenues Direct cost of revenues consists primarily of billable employee compensation and related payroll benefits, the cost of contractors assigned to revenue-generating activities and direct expenses billable to clients. Direct cost of revenues also includes expense for cloud-based computing and depreciation expense on the software used to host and process client information. Direct cost of revenues does not include an allocation of corporate overhead and non-billable segment costs.
Share-Based Compensation	Share-Based Compensation Share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period or performance period of the award. The amount of share-based compensation expense recognized at any date must at least equal the portion of grant date value of the award that is vested at that date. The fair value of restricted share awards and restricted stock units is measured based on the closing price of the underlying stock on the date of grant. The fair value of performance share units that contain market-based vesting conditions is measured using a Monte Carlo pricing model. The compensation cost of performance stock units with market-based vesting conditions is based on the grant date fair value and is not subsequently reversed if it is later determined that the market condition is unlikely to be met or is expected to be lower than originally expected. For performance share units that contain performance-based vesting conditions, the compensation cost is adjusted each reporting period based on the probability of the awards vesting. We use the Black-Scholes pricing model to determine the fair value of stock options on the date of grant. The Black-Scholes pricing model requires the development of assumptions, including volatility and expected term, which are based on our historical experience. The risk-free interest rate is based on the term of U.S. Treasury interest rates that is consistent with the expected term of the share-based award. For all our share-based awards, we recognize forfeitures in compensation cost when they occur.
Acquisition-Related Contingent Consideration	Acquisition-Related Contingent Consideration The fair value of acquisition-related contingent consideration is estimated at the acquisition date utilizing either a Monte Carlo pricing model or the present value of our probability-weighted estimate of future cash flows. Subsequent to the acquisition date, on a quarterly basis, the contingent consideration liability is remeasured at current fair value with any changes recorded in earnings. Accretion expense is recorded to acquisition-related contingent consideration liabilities for changes in fair value due to the passage of time. Remeasurement gains or losses and accretion expense are included in “Selling, general and administrative” ("SG&A") expenses on the Consolidated Statements of Comprehensive Income.
Advertising Costs	Advertising CostsAdvertising costs consist of marketing, advertising through print and other media, professional event sponsorship and public relations. These costs are expensed as incurred.
Income Taxes	Income Taxes Our income tax provision consists principally of U.S. federal, state and international income taxes. We generate income in a significant number of states located throughout the U.S. and in foreign countries in which we conduct business. Our effective income tax rate may fluctuate due to a change in the mix of earnings between higher and lower state or country tax jurisdictions and the impact of non-deductible expenses. Additionally, we record deferred tax assets and liabilities using the asset and liability method of accounting, which requires us to measure these assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of temporary differences, projected future taxable income, tax planning strategies and recent results of operations.
Cash Equivalents	Cash EquivalentsCash equivalents consist of money market funds, commercial paper and certificates of deposit with maturities of three months or less at the time of purchase.
Allowance for Expected Credit Losses	Allowance for Expected Credit Losses We estimate the current-period provision for expected credit losses on a specific identification basis. Our judgments regarding a specific client’s credit risk considers factors such as the counterparty’s creditworthiness, knowledge of the specific client’s circumstances and historical collection experience for similar clients. Other factors include, but are not limited to, current economic conditions and forward-looking estimates. Our actual experience may vary from our estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay our fees, we may need to record additional provisions for expected credit losses in future periods. The risk of credit losses may be mitigated to the extent that we received a retainer from some of our clients prior to performing services. We maintain an allowance for expected credit losses, which represents the aggregate amount of credit risk arising from the inability of specific clients to pay our fees or disputes that may affect our ability to fully collect our billed accounts receivable. We record our estimate of lifetime expected credit losses concurrently with the initial recognition of the underlying receivable. Accounts receivable, net of the allowance for expected credit losses, represents the amount we expect to collect. At each reporting date, we adjust the allowance for expected credit losses to reflect our current estimate. Adjustments to the allowance for expected credit losses are recorded to SG&A expenses on the Consolidated Statements of Comprehensive Income. Our billed accounts receivables are written off when the potential for recovery is considered remote.
Property and Equipment	Property and Equipment We record property and equipment, including improvements that extend the useful life of an asset, at cost, while maintenance and repairs are expensed as incurred. We calculate depreciation using the straight-line method based on the estimated useful life ranging from one year to seven years for furniture, equipment and software. We amortize leasehold improvements over the shorter of the estimated useful life of the asset or the lease term. We capitalize costs incurred during the application development stage of computer software developed or obtained for internal use. Capitalized software developed for internal use is classified within furniture, equipment and software and is amortized over the estimated useful life of the software, which is generally three years. Purchased software licenses to be sold to customers are capitalized and amortized over the license term.
Notes Receivable from Employees	Notes Receivable from Employees Notes receivable from employees principally include unsecured general recourse forgivable loans and retention payments, which are provided to attract and retain certain of our senior employees and other professionals. Generally, all of the principal amount and accrued interest of the forgivable loans we make to employees and other professionals will be forgiven according to the stated terms of the loan agreement, provided that the professional is providing services to the Company on the forgiveness date and upon other specified events, such as death or disability. Professionals who terminate their employment or services with us prior to the end of the forgiveness period are required to repay the outstanding, unforgiven loan balance and any accrued but unforgiven interest. If the termination was by the Company without cause or by the employee with good reason, or, subject to certain conditions, if the employee terminates his or her employment due to retirement or non-renewal of his or her employment agreement, the loan may be forgiven or continue to be forgivable, in whole or in part. We amortize forgivable loans ratably over the requisite service period, which ranges from a period of one year to 10 years. The amount of expense recognized at any date must be at least equal to the portion of the principal forgiven on the forgiveness date.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the purchase price of acquired businesses in excess of the fair market value of net assets acquired at the date of acquisition. Intangible assets may include customer relationships, trademarks and acquired software. We test our goodwill and indefinite-lived intangible assets for impairment annually as of the first day of the fourth quarter and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. On a quarterly basis, we monitor the key drivers of fair value to detect events or other changes that would warrant an interim impairment test. Important factors we consider that could trigger an interim impairment review include, but are not limited to, the following: •significant underperformance relative to expected historical or projected future operating results; •a significant change in the manner of our use of the acquired asset or the strategy for our overall business; •a significant market decline related to negative industry or economic trends; and/or •our market capitalization relative to net carrying value. We assess our goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or a business one level below that operating segment if discrete financial information is available and regularly reviewed by the chief operating decision makers. Our annual goodwill impairment test may be conducted using a qualitative assessment or a quantitative assessment. Under GAAP, we have an unconditional option to bypass the qualitative assessment and perform a quantitative impairment test. We determine whether to perform a qualitative assessment first or to bypass the qualitative assessment and proceed with the quantitative goodwill impairment test for each of our reporting units based on the excess of fair value over carrying value from the most recent quantitative tests and other events or changes in circumstances that could impact the fair value of the reporting units. In the qualitative assessment, we consider various factors, events or circumstances, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant reporting unit specific events. If, based on the qualitative assessment, we determine that it is not “more likely than not” that the fair value of a reporting unit is less than its carrying value, we do not prepare a quantitative impairment test. If we determine otherwise, we will prepare a quantitative assessment for potential goodwill impairment. In the quantitative assessment, we compare the estimated fair value of the reporting unit with the carrying amount of that reporting unit. We estimate fair value using a combination of an income approach (based on discounted cash flows) and market approaches using appropriate weighting factors. If the fair value exceeds the carrying amount, goodwill is not impaired. However, if the carrying value exceeds the fair value of the reporting unit, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Intangible assets with finite lives are amortized over their estimated useful life and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We amortize our acquired finite-lived intangible assets on a straight-line basis over periods ranging from two to 15 years.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We review long-lived assets such as property and equipment, operating lease assets and finite-lived intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These events or changes in circumstances may include a significant deterioration of operating results, changes in business plans or changes in anticipated future cash flows. If an impairment indicator is present, we evaluate recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. We group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, we estimate the fair value of the asset group to determine whether an impairment loss should be recognized.
Leases	Leases We determine if a contract is a leasing arrangement at inception. Operating lease assets represent our right to control the use of an identified asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized on the Consolidated Balance Sheets at the commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate on the commencement date in determining the present value of our lease payments. We recognize operating lease expense for our operating leases on a straight-line basis over the lease term. We lease office space and equipment under non-cancelable operating leases, which may include renewal or termination options that are reasonably certain of exercise. Most leases include one or more options to renew, with renewal terms that can extend the lease term up to seven years. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are expensed on a straight-line basis. Lease and non-lease components are accounted for together as a single lease component for operating leases associated with our office space and our equipment leases. We apply a portfolio approach for certain equipment leases to effectively account for the operating lease assets and liabilities.
Billings in Excess of Services Provided	Billings in Excess of Services Provided Billings in excess of services provided represent amounts billed to clients, such as retainers, in advance of work being performed. Clients may make advance payments, which are held on deposit until completion of work or are applied at predetermined amounts or times. Excess payments are either applied to final billings or refunded to clients upon completion of work. Payments in excess of related accounts receivable and unbilled receivables are recorded as billings in excess of services provided within the liabilities section of the Consolidated Balance Sheets.
Convertible Notes	Convertible Notes We separately recorded the liability and equity components of our 2.0% convertible senior notes due 2023 ("2023 Convertible Notes"). The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2023 Convertible Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount ("debt discount") is amortized to interest expense over the term of the 2023 Convertible Notes using the effective interest rate method. We record debt issuance costs as an adjustment to the carrying amount of the related liability and equity components of our 2023 Convertible Notes. We amortize debt discount and debt issuance costs on the liability component using the effective interest rate method over the expected life of the debt instrument. Prior to January 1, 2022, upon conversion, the 2023 Convertible Notes could be settled, at our election, in cash, shares of our common stock or a combination of cash and shares of our common stock. Effective January 1, 2022, pursuant to the first supplemental indenture, dated as of January 1, 2022 (the "First Supplemental Indenture"), to the indenture, dated as of August 20, 2018, by and between the Company and U.S. Bank National Association, as trustee (as amended by the First Supplemental Indenture, the "Indenture"), governing the 2023 Convertible Notes, t
Recently Adopted Accounting Standards and Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards In November 2020, the U.S. Securities and Exchange Commission issued Release No. 33-10890, “Management’s Discussion and Analysis, Selected Financial Data, and Supplementary Financial Information” to modernize, simplify and enhance certain financial disclosure requirements in Regulation S-K. Among other changes, the amendments enhance and clarify the disclosure requirements for liquidity and capital resources, eliminate the requirement to present five years of Selected Financial Data, replace the requirement to present two years of tabular selected quarterly financial data with a principles-based requirement to disclose when there are material retrospective changes and eliminate the tabular disclosure of contractual obligations. The company applied the amendments under the Release to this Annual Report on Form 10-K for the year ended December 31, 2021, as it is required for fiscal years ending on or after August 9, 2021. Accounting Standards Not Yet Adopted In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06 ("ASU 2020-06"), Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share calculation in certain events. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2021. We will have adopted ASU 2020-06 effective January 1, 2022, using a modified retrospective method. As permitted by the guidance, prior comparative periods will not be adjusted under this method, and a cumulative-effect adjustment of approximately $22.1 million will be recorded to the opening balance of retained earnings at the date of adoption. Pursuant to ASU 2020-06, we are no longer permitted to separately account for the liability and equity components of convertible debt instruments (such as the 2023 Convertible Notes). As such, for future periods, the entire carrying amount of the 2023 Convertible Notes will be recognized as a liability on our consolidated balance sheet. The Company estimates that adoption of this standard will result in a net increase to “Long-term debt, net” of approximately $16.4 million on the adoption date. In addition, the adoption of the standard will result in the derecognition of the embedded conversion option, net of tax effects of approximately $34.1 million which is included in “Additional paid-in capital,” as well as the derecognition of the related deferred tax liabilities of approximately $4.3 million on the Consolidated Balance Sheet. The net effect of the adoption of ASU 2020-06 for future periods is a reduction of non-cash interest expense, or an increase to net income, as there is no longer a discount from the separation of the conversion feature within equity. The discount from recognition of issuance costs will be amortized over the effective life of the 2023 Convertible Notes using the effective interest method. ASU 2020-06 also no longer allows the use of the treasury stock method for convertible instruments for purposes of calculating diluted earnings per share and instead requires application of the if-converted method. Under that method, diluted earnings per share will generally be calculated assuming that all of the convertible debt instruments were converted solely into shares of common stock at the beginning of the reporting period unless the result would be anti-dilutive. Effective January 1, 2022, pursuant to the First Supplemental Indenture, the principal amount of the 2023 Convertible Notes being converted is required to be paid in cash and only the premium due upon conversion, if any, is permitted to be settled in shares, cash or a combination of shares and cash. Consequently, the if-converted method will produce a similar result as the treasury stock method, which was used prior to the adoption of ASU 2020-06 for the 2023 Convertible Notes. We do not currently expect that the adoption of ASU 2020-06 will have a material impact on the Consolidated Statement of Cash Flows. In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance, which requires entities to provide disclosures on significant government assistance transactions for annual reporting periods. The disclosures include information around the nature of the assistance, the related accounting policies used to account for government assistance, the effect of government assistance on the entity’s financial statements, and any significant terms and conditions of the agreements, including commitments and contingencies. The new standard is effective for annual periods beginning after December 15, 2021 and impacts only annual financial statement footnote disclosures. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.

Description of Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

Our financial statements are prepared in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The consolidated financial statements include the accounts of FTI Consulting and all of our subsidiaries. All intercompany transactions and balances have been eliminated. Reclassifications of certain prior period amounts have been made to conform to the current period presentation.

Foreign Currency

Results of operations for our non-U.S. subsidiaries are translated from the designated functional currency to the reporting currency of the U.S. dollar ("USD"). Revenues and expenses are translated at average exchange rates for each month, while assets and liabilities are translated at balance sheet date exchange rates. Resulting net translation adjustments are recorded as a component of stockholders’ equity in “Accumulated other comprehensive loss.”

Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in “Interest income and other” on the Consolidated Statements of Comprehensive Income. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during the period or remains outstanding at the balance sheet date.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Due to the inherent uncertainty involved in making those assumptions, actual results could differ from those estimates. Our most significant estimates relate to revenues and the assessment of the recoverability of goodwill and intangible assets. Other estimates include, but are not limited to, the realization of deferred tax assets and the fair value of acquisition-related contingent consideration. Management bases its estimates on historical trends, projections, current experience and other assumptions that it believes are reasonable.

Concentrations of Risk

We do not have a single customer that represents 10% or more of our consolidated revenues. We derive the majority of our revenues from providing professional services to clients in the U.S. For the year ended December 31, 2021, we derived approximately 38% of our consolidated revenues from the work of professionals who are assigned to locations outside the U.S. We believe that the geographic and industry diversity of our customer base throughout the U.S. and internationally minimizes the risk of incurring material losses due to concentrations of credit risk.

Revenues

Revenue Recognition

Revenues are recognized when we satisfy a performance obligation by transferring services promised in a contract to a customer and in an amount that reflects the consideration that we expect to receive in exchange for those services. Performance obligations in our contracts represent distinct or separate services that we provide to our customers. If, at the outset of an arrangement, we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met.

We generate the majority of our revenues by providing consulting services to our clients. Most of our consulting service contracts are based on one of the following types of contract arrangements:

•Time and expense arrangements require the client to pay us based on the number of hours worked at contractually agreed-upon rates. We recognize revenues for these contract arrangements based on hours incurred and contracted rates utilizing a right-to-invoice practical expedient because we have a right to consideration for services completed to date. When a time and expense arrangement has a not-to-exceed or "cap" amount and we expect to perform work in excess of the cap, we recognize revenues up to the cap amount specified by the client, based on the efforts or hours incurred as a percentage of total efforts or hours expected to be incurred (i.e., proportional performance method).

•Fixed-fee arrangements require the client to pay a fixed fee in exchange for a predetermined set of professional services. We recognize revenues earned to date by applying the proportional performance method. Generally, these arrangements have one performance obligation.

•Performance-based or contingent arrangements represent forms of variable consideration. In these arrangements, our fees are based on the attainment of contractually defined objectives with our client, such as completing a business transaction or assisting the client in achieving a specific business objective. We recognize revenues earned to date in an amount that is probable not to reverse and by applying the proportional performance method when the criteria for over time revenue recognition are met.

Certain fees in our time and materials arrangements may be subject to approval by a third party, such as a bankruptcy court and other regulatory agency. In such cases, we record revenues based on the amount we estimate we will be entitled to in exchange for our services and only to the extent a significant reversal of revenue is not likely to occur when the uncertainty associated with the estimate is subsequently resolved. Potential fee reductions imposed by bankruptcy courts and other regulatory agencies or negotiated with specific clients are estimated on a specific identification basis. Our estimates may vary depending on the nature of the engagement, client economics, historical experience and other appropriate factors. When there are changes in our estimates of potential fee reductions, we record such changes to revenues with a corresponding offset to our billed and unbilled accounts receivable.

In our Technology segment, we generate unit-based revenues that are recognized at agreed-upon per unit rates for the amount of data stored or processed, the number of concurrent users accessing the information, or the number of pages or images processed for a client.

Reimbursable expenses, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues, and an equivalent amount of reimbursable expenses is included in costs of services in the period in which the expense is incurred.

Timing of revenue recognition often differs from the timing of billing to our customers. Generally, we transfer goods or services to a customer before the customer pays consideration or payment is due. If we have an unconditional right to invoice and receive payment for goods or services already provided, we record billed and unbilled receivables on our Consolidated Balance Sheets. Our contract terms generally include a requirement of payment within 30 days when no contingencies exist. Payment terms and conditions vary depending on the jurisdiction, market and type of service, and whether regulatory or other third-party approvals are required. At times, we may execute contracts in a form provided by customers that might include different payment terms and contracts may be negotiated at the client’s request.

Direct Cost of Revenues

Direct cost of revenues consists primarily of billable employee compensation and related payroll benefits, the cost of contractors assigned to revenue-generating activities and direct expenses billable to clients. Direct cost of revenues also includes expense for cloud-based computing and depreciation expense on the software used to host and process client information. Direct cost of revenues does not include an allocation of corporate overhead and non-billable segment costs.

Share-Based Compensation

Share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period or performance period of the award. The amount of share-based compensation expense recognized at any date must at least equal the portion of grant date value of the award that is vested at that date.

The fair value of restricted share awards and restricted stock units is measured based on the closing price of the underlying stock on the date of grant. The fair value of performance share units that contain market-based vesting conditions is measured using a Monte Carlo pricing model. The compensation cost of performance stock units with market-based vesting conditions is based on the grant date fair value and is not subsequently reversed if it is later determined that the market condition is unlikely to be met or is expected to be lower than originally expected. For performance share units that contain performance-based vesting conditions, the compensation cost is adjusted each reporting period based on the probability of the awards vesting.

We use the Black-Scholes pricing model to determine the fair value of stock options on the date of grant. The Black-Scholes pricing model requires the development of assumptions, including volatility and expected term, which are based on our historical experience. The risk-free interest rate is based on the term of U.S. Treasury interest rates that is consistent with the expected term of the share-based award.

For all our share-based awards, we recognize forfeitures in compensation cost when they occur.

The fair value of acquisition-related contingent consideration is estimated at the acquisition date utilizing either a Monte Carlo pricing model or the present value of our probability-weighted estimate of future cash flows. Subsequent to the acquisition date, on a quarterly basis, the contingent consideration liability is remeasured at current fair value with any changes recorded in earnings. Accretion expense is recorded to acquisition-related contingent consideration liabilities for changes in fair value due to the passage of time. Remeasurement gains or losses and accretion expense are included in “Selling, general and administrative” ("SG&A") expenses on the Consolidated Statements of Comprehensive Income.

Advertising Costs

Advertising CostsAdvertising costs consist of marketing, advertising through print and other media, professional event sponsorship and public relations. These costs are expensed as incurred.

Income Taxes

Our income tax provision consists principally of U.S. federal, state and international income taxes. We generate income in a significant number of states located throughout the U.S. and in foreign countries in which we conduct business. Our effective income tax rate may fluctuate due to a change in the mix of earnings between higher and lower state or country tax jurisdictions and the impact of non-deductible expenses. Additionally, we record deferred tax assets and liabilities using the asset and liability method of accounting, which requires us to measure these assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of temporary differences, projected future taxable income, tax planning strategies and recent results of operations.

Cash Equivalents

Cash EquivalentsCash equivalents consist of money market funds, commercial paper and certificates of deposit with maturities of three months or less at the time of purchase.

Allowance for Expected Credit Losses

We estimate the current-period provision for expected credit losses on a specific identification basis. Our judgments regarding a specific client’s credit risk considers factors such as the counterparty’s creditworthiness, knowledge of the specific client’s circumstances and historical collection experience for similar clients. Other factors include, but are not limited to, current economic conditions and forward-looking estimates. Our actual experience may vary from our estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay our fees, we may need to record additional provisions for expected credit losses in future periods. The risk of credit losses may be mitigated to the extent that we received a retainer from some of our clients prior to performing services.

We maintain an allowance for expected credit losses, which represents the aggregate amount of credit risk arising from the inability of specific clients to pay our fees or disputes that may affect our ability to fully collect our billed accounts receivable. We record our estimate of lifetime expected credit losses concurrently with the initial recognition of the underlying receivable. Accounts receivable, net of the allowance for expected credit losses, represents the amount we expect to collect. At each reporting date, we adjust the allowance for expected credit losses to reflect our current estimate. Adjustments to the allowance for expected credit losses are recorded to SG&A expenses on the Consolidated Statements of Comprehensive Income. Our billed accounts receivables are written off when the potential for recovery is considered remote.

Property and Equipment

We record property and equipment, including improvements that extend the useful life of an asset, at cost, while maintenance and repairs are expensed as incurred. We calculate depreciation using the straight-line method based on the estimated useful life ranging from one year to seven years for furniture, equipment and software. We amortize leasehold improvements over the shorter of the estimated useful life of the asset or the lease term. We capitalize costs incurred during the application development stage of computer software developed or obtained for internal use. Capitalized software developed for internal use is classified within furniture, equipment and software and is amortized over the estimated useful life of the software, which is generally three years. Purchased software licenses to be sold to customers are capitalized and amortized over the license term.

Notes Receivable from Employees

Notes receivable from employees principally include unsecured general recourse forgivable loans and retention payments, which are provided to attract and retain certain of our senior employees and other professionals. Generally, all of the principal amount and accrued interest of the forgivable loans we make to employees and other professionals will be forgiven according to the stated terms of the loan agreement, provided that the professional is providing services to the Company on the forgiveness date and upon other specified events, such as death or disability. Professionals who terminate their employment or services with us prior to the end of the forgiveness period are required to repay the outstanding, unforgiven loan balance and any accrued but unforgiven interest. If the termination was by the Company without cause or by the employee with good reason, or, subject to certain conditions, if the employee terminates his or her employment due to retirement or non-renewal of his or her employment agreement, the loan may be forgiven or continue to be forgivable, in whole or in part. We amortize forgivable loans ratably over the requisite service period, which ranges from a period of one year to 10 years. The amount of expense recognized at any date must be at least equal to the portion of the principal forgiven on the forgiveness date.

Goodwill and Intangible Assets

Goodwill represents the purchase price of acquired businesses in excess of the fair market value of net assets acquired at the date of acquisition. Intangible assets may include customer relationships, trademarks and acquired software.

We test our goodwill and indefinite-lived intangible assets for impairment annually as of the first day of the fourth quarter and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. On a quarterly basis, we monitor the key drivers of fair value to detect events or other changes that would warrant an interim impairment test. Important factors we consider that could trigger an interim impairment review include, but are not limited to, the following:

•significant underperformance relative to expected historical or projected future operating results;

•a significant change in the manner of our use of the acquired asset or the strategy for our overall business;

•a significant market decline related to negative industry or economic trends; and/or

•our market capitalization relative to net carrying value.

We assess our goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or a business one level below that operating segment if discrete financial information is available and regularly reviewed by the chief operating decision makers.

Our annual goodwill impairment test may be conducted using a qualitative assessment or a quantitative assessment. Under GAAP, we have an unconditional option to bypass the qualitative assessment and perform a quantitative impairment test. We determine whether to perform a qualitative assessment first or to bypass the qualitative assessment and proceed with the quantitative goodwill impairment test for each of our reporting units based on the excess of fair value over carrying value from the most recent quantitative tests and other events or changes in circumstances that could impact the fair value of the reporting units.

In the qualitative assessment, we consider various factors, events or circumstances, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant reporting unit specific events. If, based on the qualitative assessment, we determine that it is not “more likely than not” that the fair value of a reporting unit is less than its carrying value, we do not prepare a quantitative impairment test. If we determine otherwise, we will prepare a quantitative assessment for potential goodwill impairment.

In the quantitative assessment, we compare the estimated fair value of the reporting unit with the carrying amount of that reporting unit. We estimate fair value using a combination of an income approach (based on discounted cash flows) and market approaches using appropriate weighting factors. If the fair value exceeds the carrying amount, goodwill is not impaired. However, if the carrying value exceeds the fair value of the reporting unit, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

Intangible assets with finite lives are amortized over their estimated useful life and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We amortize our acquired finite-lived intangible assets on a straight-line basis over periods ranging from two to 15 years.

Impairment of Long-Lived Assets

We review long-lived assets such as property and equipment, operating lease assets and finite-lived intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These events or changes in circumstances may include a significant deterioration of operating results, changes in business plans or changes in anticipated future cash flows. If an impairment indicator is present, we evaluate recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. We group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, we estimate the fair value of the asset group to determine whether an impairment loss should be recognized.

Leases

We determine if a contract is a leasing arrangement at inception. Operating lease assets represent our right to control the use of an identified asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized on the Consolidated Balance Sheets at the commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate on the commencement date in determining the present value of our lease payments. We recognize operating lease expense for our operating leases on a straight-line basis over the lease term.

We lease office space and equipment under non-cancelable operating leases, which may include renewal or termination options that are reasonably certain of exercise. Most leases include one or more options to renew, with renewal terms that can extend the lease term up to seven years. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are expensed on a straight-line basis. Lease and non-lease components are accounted for together as a single lease component for operating leases associated with our office space and our equipment leases. We apply a portfolio approach for certain equipment leases to effectively account for the operating lease assets and liabilities.

Billings in Excess of Services Provided

Billings in excess of services provided represent amounts billed to clients, such as retainers, in advance of work being performed. Clients may make advance payments, which are held on deposit until completion of work or are applied at predetermined amounts or times. Excess payments are either applied to final billings or refunded to clients upon completion of work. Payments in excess of related accounts receivable and unbilled receivables are recorded as billings in excess of services provided within the liabilities section of the Consolidated Balance Sheets.

Convertible Notes

We separately recorded the liability and equity components of our 2.0% convertible senior notes due 2023 ("2023 Convertible Notes"). The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2023 Convertible Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount ("debt discount") is amortized to interest expense over the term of the 2023 Convertible Notes using the effective interest rate method.

We record debt issuance costs as an adjustment to the carrying amount of the related liability and equity components of our 2023 Convertible Notes. We amortize debt discount and debt issuance costs on the liability component using the effective interest rate method over the expected life of the debt instrument. Prior to January 1, 2022, upon conversion, the 2023 Convertible Notes could be settled, at our election, in cash, shares of our common stock or a combination of cash and shares of our common stock. Effective January 1, 2022, pursuant to the first supplemental indenture, dated as of January 1, 2022 (the "First Supplemental Indenture"), to the indenture, dated as of August 20, 2018, by and between the Company and U.S. Bank National Association, as trustee (as amended by the First Supplemental Indenture, the "Indenture"), governing the 2023 Convertible Notes, t

Recently Adopted Accounting Standards and Accounting Standards Not Yet Adopted

Recently Adopted Accounting Standards

In November 2020, the U.S. Securities and Exchange Commission issued Release No. 33-10890, “Management’s Discussion and Analysis, Selected Financial Data, and Supplementary Financial Information” to modernize, simplify and enhance certain financial disclosure requirements in Regulation S-K. Among other changes, the amendments enhance and clarify the disclosure requirements for liquidity and capital resources, eliminate the requirement to present five years of Selected Financial Data, replace the requirement to present two years of tabular selected quarterly financial data with a principles-based requirement to disclose when there are material retrospective changes and eliminate the tabular disclosure of contractual obligations. The company applied the amendments under the Release to this Annual Report on Form 10-K for the year ended December 31, 2021, as it is required for fiscal years ending on or after August 9, 2021.

Accounting Standards Not Yet Adopted

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06 ("ASU 2020-06"), Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share calculation in certain events. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2021. We will have adopted ASU 2020-06 effective January 1, 2022, using a modified retrospective method. As permitted by the guidance, prior comparative periods will not be adjusted under this method, and a cumulative-effect adjustment of approximately $22.1 million will be recorded to the opening balance of retained earnings at the date of adoption.

Pursuant to ASU 2020-06, we are no longer permitted to separately account for the liability and equity components of convertible debt instruments (such as the 2023 Convertible Notes). As such, for future periods, the entire carrying amount of the 2023 Convertible Notes will be recognized as a liability on our consolidated balance sheet. The Company estimates that adoption of this standard will result in a net increase to “Long-term debt, net” of approximately $16.4 million on the adoption date. In addition, the adoption of the standard will result in the derecognition of the embedded conversion option, net of tax effects of approximately $34.1 million which is included in “Additional paid-in capital,” as well as the derecognition of the related deferred tax liabilities of approximately $4.3 million on the Consolidated Balance Sheet.

The net effect of the adoption of ASU 2020-06 for future periods is a reduction of non-cash interest expense, or an increase to net income, as there is no longer a discount from the separation of the conversion feature within equity. The discount from recognition of issuance costs will be amortized over the effective life of the 2023 Convertible Notes using the effective interest method.

ASU 2020-06 also no longer allows the use of the treasury stock method for convertible instruments for purposes of calculating diluted earnings per share and instead requires application of the if-converted method. Under that method, diluted earnings per share will generally be calculated assuming that all of the convertible debt instruments were converted solely into shares of common stock at the beginning of the reporting period unless the result would be anti-dilutive. Effective January 1, 2022, pursuant to the First Supplemental Indenture, the principal amount of the 2023 Convertible Notes being converted is required to be paid in cash and only the premium due upon conversion, if any, is permitted to be settled in shares, cash or a combination of shares and cash. Consequently, the if-converted method will produce a similar result as the treasury stock method, which was used prior to the adoption of ASU 2020-06 for the 2023 Convertible Notes. We do not currently expect that the adoption of ASU 2020-06 will have a material impact on the Consolidated Statement of Cash Flows.

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance, which requires entities to provide disclosures on significant government assistance transactions for annual reporting periods. The disclosures include information around the nature of the assistance, the related accounting policies used to account for government assistance, the effect of government assistance on the entity’s financial statements, and any significant terms and conditions of the agreements, including commitments and contingencies. The new standard is effective for annual periods beginning after December 15, 2021 and impacts only annual financial statement footnote disclosures. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.
