Business Description and Basis of Presentation	Mar. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation	Business Description and Basis of Presentation Global Business Travel Group, Inc. (“GBTG”), and its consolidated subsidiaries (GBTG together with its consolidated subsidiaries, the "Company"), including GBT JerseyCo Limited (“GBT JerseyCo”), is a leading business-to-business software and services company in travel and expense. The Company provides a platform serving travel primarily for business purposes and a full suite of differentiated, technology-enabled solutions to business travelers and clients, suppliers of travel content (such as airlines, hotels, ground transportation and aggregators) and third-party travel agencies. The Company manages end-to-end logistics of business travel and provides a link between businesses and their employees, travel suppliers, and other industry participants. GBTG is a Delaware corporation and tax resident in the United States of America (“U.S.”). The Company has one reportable segment. Potential Acquisition of CWT On March 24, 2024, GBTG entered into an Agreement and Plan of Merger (the “Merger Agreement”) with CWT Holdings, LLC, a Delaware limited liability company (“CWT”), pursuant to which, among other things, GBTG will acquire CWT. The transaction values CWT at approximately $570 million on a cash-free and debt-free basis, subject to certain assumptions and purchase price adjustments. At the closing of the transaction, GBTG expects to fund the acquisition with a combination of cash and an aggregate of approximately 72 million shares of its Class A common stock, par value $0.0001 per share ("Class A common stock"), at a price of $6.00 per share as purchase consideration. The transaction is expected to be completed in the second half of 2024, subject to the satisfaction of customary closing conditions, including the receipt of certain regulatory approvals. Basis of Presentation The Company’s consolidated financial statements include the accounts of GBTG, its wholly-owned subsidiaries and entities controlled by GBTG. There are no entities that have been consolidated due to control through operating agreements, financing agreements or as the primary beneficiary of a variable interest entity. The Company reports the non-controlling ownership interests in subsidiaries that are held by third-party owners as equity attributable to non-controlling interests in subsidiaries on the consolidated balance sheets. The portion of income or loss attributable to third-party owners for the reporting period is reported as net income (loss) attributable to non-controlling interests in subsidiaries on the consolidated statements of operations. The Company has eliminated intercompany transactions and balances in its consolidated financial statements. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial reporting. As such, certain notes or other information that are normally required by U.S. GAAP have been omitted if they substantially duplicate the disclosures contained in the Company’s annual audited consolidated financial statements. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023, included in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission, United States (the “SEC”) on March 13, 2024 (the “Annual Report on Form 10-K”). The Company has included all normal recurring items and adjustments necessary for a fair presentation of the results of the interim period. The Company’s interim unaudited consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. Certain prior period amounts within the consolidated statements of operations and consolidated statements of cash flows have been reclassified to conform to current year presentation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures in the consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, supplier revenue, allowance for credit losses, depreciable lives of property and equipment, acquisition purchase price allocations including valuation of acquired intangible assets and goodwill and contingent consideration, valuation of operating lease right-of-use (“ROU”) assets, impairment of goodwill, other intangible assets, long-lived assets, capitalized client incentives and investments in equity method investments, valuation allowances on deferred income taxes, valuation of pensions, interest rate swaps, earnout shares and contingent liabilities. Actual results could differ materially from those estimates.

Recently Issued Accounting Pronouncements	Mar. 31, 2024
Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Pronouncements - Adopted The Company did not adopt any new accounting pronouncements during the three months ended March 31, 2024. Accounting Pronouncements - Not Yet Adopted There were no new accounting standards or pronouncements that were issued during the three months ended March 31, 2024 that the Company expects to have a material impact on its consolidated financial statements. However, the Company has yet to adopt the following accounting standard updates ("ASU") issued by the Financial Accounting Standards Board (the "FASB"). Segment Reporting In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which expands the segment reporting disclosures and primarily requires disclosures on (i) significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and are included within each reported measure of segment operating results, (ii) the total amount of any other items included in segment operating results which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items and (iii) CODM’s title and position and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing performance and deciding how to allocate resources. The update also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis, with early adoption permitted. While the update will require additional disclosures related to the Company’s segment, it is not expected to have any impact on the Company’s consolidated operating results, financial condition or cash flows. Income Taxes In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The update primarily requires the Company to provide (i) further disaggregation for specific categories on the effective tax rate reconciliation, as well as additional information about federal, state/local and foreign income taxes and (ii) annually disclose its income taxes paid (net of refunds received), disaggregated by jurisdiction. The update is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The update is to be applied on a prospective basis, although optional retrospective application is permitted. While the update will require additional disclosures related to the Company’s income taxes, it is not expected to have any impact on the Company’s consolidated operating results, financial condition or cash flows.

Revenue from Contracts with Customers

3 Months Ended

Mar. 31, 2024

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

The Company disaggregates revenue based on (i) Travel Revenue which includes all revenue relating to servicing a transaction, which can be air, hotel, car rental, rail or other travel-related booking or reservation, and (ii) Product and Professional Services Revenue which includes all revenue relating to using the Company’s platform, products and value-added services. The following table presents the Company’s disaggregated revenue by nature of service. Sales and usage-based taxes are excluded from revenue.


	Three months ended March 31,
(in $ millions)	2024		2023
Travel revenue	$	492	$	467
Product and professional services revenue	118		111
Total revenue	$	610	$	578

Payments from customers are generally received within 30-60 days of invoicing or from their contractual date agreed under the terms of contract.

Contract Balances

Contract assets represent the Company’s right to consideration in exchange for services transferred to a customer when that right is conditioned on the Company’s future performance obligations. Contract liabilities represent the Company’s obligation to transfer services to a customer for which the Company has received consideration (or the amount is due) from the customer.

The opening and closing balances of the Company’s accounts receivable, net, and contract liabilities are as follows:


			Contract liabilities
(in $ millions)	Accounts receivable, net		Client incentives, net (non-current)		Deferred revenue (current)
Balance as of March 31, 2024	$	811	$	10	$	30
Balance as of December 31, 2023	$	725	$	9	$	19

Accounts receivable, net, exclude balances not related to contracts with customers.

Deferred revenue is recorded when a performance obligation has not been satisfied but an invoice has been raised. Cash payments received from customers in advance of the Company completing its performance obligations are included in deferred revenue in the Company’s consolidated balance sheets. The Company generally expects to complete its performance obligations under the contracts within one year. During the three months ended March 31, 2024, the cash payments received or due in advance of the satisfaction of the Company’s performance obligations were offset by $10 million of revenue recognized that was included in the deferred revenue balance as of December 31, 2023.

Remaining Performance Obligations

The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less. The Company did not have any material transaction price allocated to performance obligations under the contracts over one year that remain unsatisfied as at March 31, 2024.

- 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.

Adjusted SOFR floor of 1.00% applies to the tranche B-3 and tranche B-4 term loans and borrowings under the senior secured revolving credit facility. Improvement in the Company's leverage ratio, computed in a manner as provided in the senior secured credit agreement, resulted in a decrease in its interest rate margins during the three months ended March 31, 2024. As of March 31, 2024 and December 31, 2023, (i) interest on each of tranche B-3 and tranche B-4 term loans was based on Adjusted SOFR plus 5.25% and Adjusted SOFR plus 6.00%, respectively, and (ii) interest on the revolving credit facility was based on Adjusted SOFR plus 4.75% and Adjusted SOFR plus 5.50%, respectively.

Under the terms of the senior secured credit agreement, the senior secured revolving credit facility will automatically terminate on May 14, 2025 if the senior secured initial term loans have not been refinanced, replaced or extended (with a resulting maturity date that is December 16, 2026 or later) or repaid in full prior to May 14, 2025. Further, the senior secured revolving credit facility has (i) a $30 million sublimit for extensions of credit denominated in certain currencies other than U.S. dollars, (ii) a $10 million sublimit for letters of credit, and (iii) a $10 million sublimit for swingline borrowings. Extensions of credit under the senior secured revolving credit facility are subject to customary borrowing conditions. The Company is required to pay a fee of 0.375% per annum on the average daily unused commitments under the senior secured revolving credit facility, payable quarterly in arrears. As of March 31, 2024, the Company had a balance of $50 million that remained undrawn under the senior secured revolving credit facility. As of December 31, 2023, the Company had utilized $7 million for letters of credit and had the balance of $43 million that remained undrawn under the senior secured revolving credit facility.

Interest on the senior secured credit facilities is payable quarterly in arrears (or, if earlier in the case of LIBOR and SOFR loans, at the end of the applicable interest period). The effective interest rate on the senior secured term loans for the three months ended March 31, 2024 was approximately 11.2%.

Other borrowings primarily relate to finance leases and equipment sale and lease back transaction.

Security; Guarantees

GBT UK TopCo Limited, a wholly-owned indirect subsidiary of GBTG, and certain of its direct and indirect subsidiaries, as guarantors (such guarantors, collectively with GBT Group Services B.V. (a wholly-owned indirect subsidiary of GBTG and the borrower under the senior secured credit agreement), the “Loan Parties”), provide an unconditional guarantee, on a joint and several basis, of all obligations under the senior secured credit facilities and under cash management agreements and swap contracts with the lenders or their affiliates (with certain limited exceptions). Subject to certain cure rights, as of the end of each fiscal quarter, at least 70% of the consolidated total assets of the Loan Parties and their subsidiaries must be attributable, in the aggregate, to the Loan Parties; provided that such coverage test shall instead be calculated based on 70% of Consolidated EBITDA (as defined in the senior secured credit agreement) of the Loan Parties and their subsidiaries for the four prior fiscal quarters, commencing with the first quarterly test date after January 2021 on which Consolidated EBITDA of the Loan Parties and their subsidiaries exceeds $100 million. Further, the lenders have a first priority security interest in substantially all of the assets of the Loan Parties.

Covenants

The senior secured credit agreement contains various affirmative and negative covenants, including certain financial covenants (see below) and limitations (subject to exceptions) on the ability of the Loan Parties and their subsidiaries to: (i) incur indebtedness or issue preferred stock; (ii) incur liens on their assets; (iii) consummate certain fundamental changes (such as acquisitions, mergers, liquidations or changes in the nature of the business); (iv) dispose of all or any part of their assets; (v) pay dividends or other distributions with respect to, or repurchase, any equity interests of any Loan Party or any equity interests of any direct or indirect parent company or subsidiary of any Loan Party; (vi) make investments, loans or advances; (vii) enter into transactions with affiliates and certain other permitted holders; (viii) modify the terms of, or prepay, any of their subordinated or junior lien indebtedness; (ix) make certain changes to a Loan Party’s entity classification for U.S. federal income tax purposes or certain intercompany transfers of a Loan Party’s assets if, as a result thereof, an entity would cease to be a Loan Party due to adverse tax consequences; (x) enter into swap contracts; and (xi) enter into certain burdensome agreements.

The senior secured credit agreement also requires that an aggregate amount of Liquidity (as defined in the senior secured credit agreement) equal to at least $200 million be maintained as of the end of each calendar month. Liquidity is calculated as the aggregate amount of unrestricted cash and cash equivalents of the Loan Parties and their subsidiaries plus, under certain circumstances, the unused amount available to be drawn under the senior secured revolving credit facility.

The senior secured credit agreement also contains an additional financial covenant applicable solely to the senior secured revolving credit facility. Such financial covenant requires the first lien net leverage ratio (calculated in a manner set forth under the senior secured credit agreement) to be less than or equal to 3.50 to 1.00 as of the last day of any fiscal quarter on which the aggregate principal amount of outstanding loans and letters of credit under the senior secured revolving credit facility exceeds 35% of the aggregate principal amount of the senior secured revolving credit facility. The senior secured credit agreement provides that such financial covenant is suspended for a limited period of time if an event that constitutes a “Travel MAC” (as defined in the senior secured credit agreement) has occurred and the Loan Parties are unable to comply with such covenant as a result of such event. Such financial covenant did not apply for the period ended March 31, 2024.

As of March 31, 2024, the Loan Parties and their subsidiaries were in compliance with all applicable covenants under the senior secured credit agreement.

Events of Default

The senior secured credit agreement contains default events (subject to certain materiality thresholds and grace periods), which could require early prepayment, termination of the senior secured credit agreement or other enforcement actions customary for facilities of this type. As of March 31, 2024, no event of default existed under the senior secured credit agreement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Commitment In the ordinary course of business, the Company makes various commitments to purchase goods and services from specific suppliers, including those related to capital expenditures. As of March 31, 2024, the Company had approximately $223 million of outstanding non-cancellable purchase commitments, primarily relating to service, hosting, licensing and other information technology contracts, of which $94 million relates to the twelve months ending March 31, 2025. These purchase commitments extend through 2031. Guarantees The Company has obtained bank guarantees in respect of certain travel suppliers and real estate lease agreements amounting to $27 million. Certain of these bank guarantees require the Company to maintain cash collateral which has been presented as restricted cash within other non-current assets in the Company’s consolidated balance sheet. Legal Contingencies The Company recognizes legal fees as expense when the legal services are provided. Based on its current knowledge, and taking into consideration its litigation-related liabilities, the Company believes it is not a party to any pending legal proceeding or governmental examination that would have a material adverse effect on the Company’s consolidated financial condition or liquidity. Commitment and/or Contingency Related to the Merger Agreement The Merger Agreement, as discussed in note 1 - Business Description and Basis of Presentation, contains certain termination rights for each of GBTG and CWT, including the failure of the merger to be consummated by January 24, 2025 (the “Drop Dead Date”), which may be extended at the option of GBTG or CWT to May 24, 2025 (the “Extended Drop Dead Date”) and subsequently extended to September 24, 2025 (the “Second Extended Drop Dead Date”), in each case, if all conditions to the closing, other than certain conditions relating to antitrust laws or foreign investment laws, have been satisfied or waived on or prior to such date. If the Merger Agreement is terminated in certain instances for failure to consummate the merger by the Drop Dead Date (as a result of certain conditions relating to antitrust laws or foreign investment laws failing to be satisfied or waived), GBTG will be required to pay CWT a termination fee of $32 million. If GBTG, but not CWT, extends the Drop Dead Date and the Merger Agreement is subsequently terminated in certain instances for failure to consummate the merger by the Extended Drop Dead Date (as a result of certain conditions relating to antitrust laws or foreign investment laws failing to be satisfied or waived), GBTG will be required to pay CWT a termination fee of $33.5 million. If GBTG, but not CWT, extends the Extended Drop Dead Date and the Merger Agreement is subsequently terminated in certain instances for failure to consummate the merger by the Second Extended Drop Dead Date (as a result of certain conditions relating to antitrust laws or foreign investment laws failing to be satisfied or waived), GBTG will be required to pay CWT a termination fee of $35 million.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesFor the three months ended March 31, 2024 and March 31, 2023, the Company’s provision for (benefit from) income tax expense was $27 million and $(8) million, respectively, and its effective tax rate was 333.78% and 23.88%, respectively. GBTG’s effective tax rate for the three months ended March 31, 2024 is higher than the U.S. federal statutory corporate income tax rate of 21% due to an increase to the valuation allowance for deferred tax assets, non-deductible expenses and the U.S. base erosion minimum taxes. The impact of these items has a greater impact on the effective tax rate due to the low pre-tax net income.

Earnout Shares	3 Months Ended
Earnout Shares	Mar. 31, 2024
Earnout Shares
Earnout Shares	Earnout Shares Certain stockholders and employees are entitled to additional consideration in the form of “earnout shares” of the Company’s Class A common stock, to be issued in tranches, when the Company’s Class A common stock’s price achieves certain market share price milestones within specified periods. The earnout shares to stockholders are accounted under Accounting Standard Codification 815, “Derivatives and Hedging” (“ASC 815”). Such guidance provides that because the earnout shares do not meet the criteria for equity treatment thereunder, earnout shares must be recorded as a liability. This liability is subject to re-measurement at each balance sheet date. With each such re-measurement, the earnout shares liability is adjusted to its fair value, with the change in fair value recognized in the Company’s consolidated statements of operations. The fair value of the earnout shares is estimated using the Monte Carlo simulation of the stock prices based on historical and implied market volatility (see note 15 – Fair Value Measurements). As of March 31, 2024 the fair value of the earnout shares derivative liability was estimated to be $59 million. The Company recognized a gain on the fair value change in earnout shares derivative liability of $18 million and $3 million in its consolidated statement of operations for the three months ended March 31, 2024 and March 31, 2023, respectively.

There has been no material movements in the Company's issued and outstanding stock options during the three months ended March 31, 2024.

2022 Equity Incentive Plan

During the three months ended March 31, 2024, as part of its annual grant program, the Company granted 12 million RSUs under the 2022 Equity Incentive Plan to certain of its key employees. The RSUs generally vest one-third annually on the first three anniversaries of the grant date. The vesting is conditional upon continued employment of the grantee through the applicable vesting period and subject to such other terms and conditions as set forth in the applicable restricted stock unit award agreement. The RSUs do not accrue dividends or dividend equivalent rights associated with the underlying stock. The fair value of the RSUs is determined to be the market price of the Company’s Class A common stock at the date of grant.

The table below presents the activity of the Company’s RSUs for the three months ended March 31, 2024:


	Number of RSUs	Weighted average grant date fair value
Balance as of December 31, 2023	24,435,324	$	6.86

Vested	(7,895,197)	$	6.85
Balance as of March 31, 2024	28,146,760	$	6.29

During the three months ended March 31, 2024, the vested RSUs were net-share settled such that the Company withheld shares with value equivalent to no more than the employee’s maximum statutory obligation for applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. A total of 3,208,148 shares were withheld and were based on the value of the RSUs on their respective vesting dates as determined by the Company’s closing stock price. Total employees’ tax obligations to taxing authorities was $19 million of which $12 million was paid during the three months ended March 31, 2024 and is reflected as a financing activity within the consolidated statements of cash flows.

Employee Stock Purchase Plan (“ESPP”)

As of March 31, 2024, there were 13.9 million shares available for issuance under the ESPP. During the three months ended March 31, 2024, 836,436 shares were purchased under the ESPP.

Total equity-based compensation expense recognized in the Company’s consolidated statements of operations for the three months ended March 31, 2024 and 2023 amount to $18 million and $19 million, respectively (net of tax of $14 million and $14 million, respectively), and were included as follows:

Total	$	18	$	19

As of March 31, 2024, the Company expects compensation expense related to (i) unvested stock options of approximately $2 million to be recognized over the remaining weighted average period of less than 1 year and (ii) unvested RSUs of approximately $150 million to be recognized over the remaining weighted average period of 2.2 years.

Earnings (Loss) Per Share

3 Months Ended

Mar. 31, 2024

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Basic earnings (loss) per share is based on the average number of shares of Class A common stock outstanding during the period. Diluted earnings (loss) per share is based on the average number of shares of Class A common stock used for the basic earnings per share calculation, adjusted for the dilutive effect of (i) stock options and RSUs using the “treasury stock” method, and (ii) GBTG’s Class B common stock, using the “if converted” method, for the period they were outstanding.

The Company has issued and outstanding approximately 23 million earnout shares, which are subject to forfeiture if the achievement of certain stock price thresholds are not met. In accordance with ASC 260, “Earnings Per Share,” earnout shares are excluded from weighted-average shares outstanding to calculate basic earnings (loss) per share as they are considered contingently issuable shares due to their potential forfeiture. Earnout shares will be included in weighted-average shares outstanding to calculate basic earnings (loss) per share as of the date their stock price thresholds are met and they are no longer subject to forfeiture. Additionally, dividends accrued on earnout shares, if any, will be forfeited if the pricing thresholds for earnout shares are not met during the specified time period.

The Company has excluded approximately (i) 20 million and 21 million of stock options and (ii) 28 million and 27 million of RSUs from the calculation of diluted loss per share for the three months ended March 31, 2024 and 2023, respectively, as their inclusion would have resulted in anti-dilutive effect on loss per share.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging

Except as mentioned below, the Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risks. The Company does not hold or issue financial instruments for speculative or trading purposes. The Company does not offset derivative assets and liabilities within the consolidated balance sheets.

Interest Rate Swap

The Company is subject to market risk exposure arising from changes in interest rates on debt, which bears interest at variable rates. The Company has interest rate risk primarily related to its senior secured term loans under the senior secured

credit agreement, which bear interest at a variable rate that is currently based on synthetic LIBOR or SOFR (subject to certain benchmark replacement provisions and certain interest rate floors, as applicable). In order to protect against potential higher interest costs resulting from anticipated increases in the benchmark rate for the senior secured tranche B-3 term loans, GBT Group Services B.V., has entered into interest rate swap contracts (discussed below) that fixed the benchmark interest rate with respect to a portion of the senior secured tranche B-3 term loans.

In June 2022, the Company entered into an interest rate swap contract (subsequently amended in March 2023) for a notional amount of $600 million. The terms of this agreement require the Company to receive a variable rate of three months SOFR, and pay fixed rate of 3.6800%. This contract matures in March 2025.

In February 2023, the Company entered into another interest rate swap contract for a notional amount of $300 million. The terms of the agreement require the Company to receive a variable rate of three months SOFR, with a floor of 0.90%, and pay fixed rate of 4.295%. This contract matures in March 2027.

The above interest rate swaps are designated as a cash flow hedges that are highly effective at offsetting the increases in cash outflows when three-month SOFR based-rate exceeds the respective fixed rates.

Earnout Shares

GBTG has issued and outstanding earnout shares (see note 10 – Earnout Shares) which are accounted for as derivative instruments. As of March 31, 2024, the total number of earnout shares issued and outstanding were approximately 23 million.

The following table presents the balance sheet location and fair value of the Company’s derivative instruments, on a gross basis, under ASC 815:


(in $ millions)	Balance sheet Location	March 31, 2024		December 31, 2023
Derivatives designated as hedging instruments
Interest rate swaps	Other non-current assets	$	8	$	7
Interest rate swaps	Other non-current (liabilities)	$	(1)	$	(5)
Derivatives not designated as hedging instruments
Earnout shares	Earnout derivative liabilities	$	59	$	77

The table below presents the impact of changes in fair values of derivatives on other comprehensive income (loss) and on net loss:


	Amount of gain/(loss) recognized in other comprehensive income (loss)				Statement of operations location	Amount of gain/(loss) recognized in statements of operations
	Three months ended March 31,						Three months ended March 31,
	2024		2023					2024		2023

Derivatives not designated as hedging instruments
Earnout Shares	—		—				Fair value movement on earnout derivative liabilities	18		3

The total gain of $8 million on the interest rate swap contract is expected to be reclassified to net earnings as a credit to interest expense within the next 12 months.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Financial instruments which are measured at fair value, or for which a fair value is disclosed, are classified in the fair value hierarchy, as outlined below, on the basis of the observability of the inputs used in the fair value measurement:

Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2 — Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices in non-active markets or for which all significant inputs, other than quoted prices, are observable either directly or indirectly, or for which unobservable inputs are corroborated by market data.

Level 3 — Valuations based on inputs that are unobservable and significant to overall fair value measurement.

As of March 31, 2024, the Company’s financial assets and liabilities recorded at fair value on a recurring basis consist of its derivative instruments — interest rate swaps and non-employee earnout shares. The fair value of the Company’s interest rate swaps has been primarily calculated by using a discounted cash flow analysis by taking the present value of the fixed and floating rate cash flows utilizing the appropriate forward SOFR curves and the counterparty’s credit risk, which was determined to be not material. The fair value of non-employee earnout shares is determined using the Monte Carlo valuation method.

Presented below is a summary of the gross carrying value and fair value of the Company’s assets and liabilities measured at a fair value on a recurring basis:


		Asset/ (Liability)
(in $ millions)	Fair Value Hierarchy	March 31, 2024		December 31, 2023
Interest rate swaps asset	Level 2	$	8	$	7
Interest rate swap liability	Level 2	(1)		(5)
Non-employee earnout shares	Level 3	(59)		(77)

Inherent in the Monte Carlo valuation method are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimated the volatility of the earnout shares based on weighted average of its own share price volatility and implied historical volatility of select peer companies’ common stock that matches the expected remaining life of the earnout shares. The risk-free interest rate was based on the U.S. Treasury zero-coupon yield curve for a maturity similar to the expected remaining life of the earnout shares. The expected life of the earnout shares was assumed to be equivalent to their remaining contractual term. The Company anticipated the dividend rate will remain at zero.

The following table presents the assumptions used for the measurement of the fair value of outstanding earnout shares liabilities:


	March 31, 2024		December 31, 2023
Stock price ($)	$	6.01	$	6.45
Risk-free interest rate	4.38%		3.98%
Volatility	45.0%		47.5%
Expected term (years)	3.2		3.4
Expected dividends	0.0%		0.0%

Fair value ($) (per earnout share – Tranche 1)	$	2.92	$	3.71
Fair value ($) (per earnout share – Tranche 2)	$	2.21	$	3.02

The following table presents changes in Level 3 financial liabilities measured at fair value during the three months March 31, 2024:


(in $ millions)	Earnout Shares
Balance as of December 31, 2023	$	77
Change in fair value	(18)
Balance as of March 31, 2024	$	59

The Company does not measure its debt at fair value in its consolidated balance sheets. Where the fair value of the Company’s long-term debt is determined based on quoted prices in inactive markets for identical debt instruments, or for similar debt instruments, when traded as assets, it is categorized within Level 2 of the fair value hierarchy. Where quoted prices are not available, fair value is estimated using discounted cash flows and market-based expectation of interest rates, credit risks and the contractual term of the debt instruments and is categorized within Level 3 of the fair value hierarchy.

The fair values of the Company’s outstanding senior secured term loans are as follows:


		March 31, 2024				December 31, 2023
(in $ millions)	Fair Value Hierarchy	Carrying amount(1)		Fair value		Carrying amount (1)		Fair value
Senior secured initial term loans	Level 2	$	234	$	236	$	234	$	236
Senior secured tranche B-3 term loans	Level 3	$	991	$	1,011	$	990	$	1,013
Senior secured tranche B-4 term loans	Level 3	$	132	$	136	$	132	$	137

_____________________________________________________________

(1)Outstanding principal amount of the relevant class of senior secured term loans less unamortized debt discount and debt issuance costs with respect to such loans.

The carrying amounts of cash and cash equivalents, accounts receivable, due from affiliates, other current assets, accounts payable, due to affiliates and accrued expenses and other current liabilities approximate fair value due to the short-term maturities of these assets and liabilities.

Certain assets and liabilities, including long-lived assets, goodwill and other intangible assets, are measured at fair value on a non-recurring basis.

Recently Issued Accounting Pronouncements (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures in the consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, supplier revenue, allowance for credit losses, depreciable lives of property and equipment, acquisition purchase price allocations including valuation of acquired intangible assets and goodwill and contingent consideration, valuation of operating lease right-of-use (“ROU”) assets, impairment of goodwill, other intangible assets, long-lived assets, capitalized client incentives and investments in equity method investments, valuation allowances on deferred income taxes, valuation of pensions, interest rate swaps, earnout shares and contingent liabilities. Actual results could differ materially from those estimates.
Accounting Pronouncements - Adopted and Not Yet Adopted	Accounting Pronouncements - Adopted The Company did not adopt any new accounting pronouncements during the three months ended March 31, 2024. Accounting Pronouncements - Not Yet Adopted There were no new accounting standards or pronouncements that were issued during the three months ended March 31, 2024 that the Company expects to have a material impact on its consolidated financial statements. However, the Company has yet to adopt the following accounting standard updates ("ASU") issued by the Financial Accounting Standards Board (the "FASB").
Segment Reporting	Segment Reporting In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which expands the segment reporting disclosures and primarily requires disclosures on (i) significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and are included within each reported measure of segment operating results, (ii) the total amount of any other items included in segment operating results which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items and (iii) CODM’s title and position and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing performance and deciding how to allocate resources. The update also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis, with early adoption permitted. While the update will require additional disclosures related to the Company’s segment, it is not expected to have any impact on the Company’s consolidated operating results, financial condition or cash flows.
Income Taxes	Income Taxes In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The update primarily requires the Company to provide (i) further disaggregation for specific categories on the effective tax rate reconciliation, as well as additional information about federal, state/local and foreign income taxes and (ii) annually disclose its income taxes paid (net of refunds received), disaggregated by jurisdiction. The update is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The update is to be applied on a prospective basis, although optional retrospective application is permitted. While the update will require additional disclosures related to the Company’s income taxes, it is not expected to have any impact on the Company’s consolidated operating results, financial condition or cash flows.

- Definition

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
