Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1: Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared under accounting principles generally accepted in the United States ("U.S. GAAP" or "GAAP") and in conformity with rules applicable to quarterly reports on Form 10-Q. The Condensed Consolidated Financial Statements as of June 30, 2022 and for the three and six months ended June 30, 2022 and 2021 are unaudited. All adjustments, consisting of normal recurring adjustments, except as otherwise noted, considered necessary for a fair presentation of the unaudited interim Condensed Consolidated Financial Statements for these interim periods have been included. Readers of this unaudited condensed consolidated quarterly financial information should refer to the audited Consolidated Financial Statements and notes thereto of Cushman & Wakefield plc and its subsidiaries (“Cushman & Wakefield,” the "Company,” “we,” “our” and “us”) for the year ended December 31, 2021 included in our 2021 Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the "SEC") and also available on our website (www.cushmanwakefield.com). Certain footnote disclosures that would substantially duplicate those contained in such audited financial statements or which are not required by the rules and regulations of the SEC for interim financial statement presentation have been condensed or omitted. Refer to Note 2: Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements in the Company's 2021 Annual Report on Form 10-K for further discussion of the Company's accounting policies and estimates. Due to seasonality, the results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2022. The Company provides for the effects of income taxes on interim financial statements based on estimates of the effective tax rate for the full year, which is based on forecasted income by country and enacted tax rates.

New Accounting Standards

Accounting Policies [Abstract]
New Accounting Standards	Note 2: New Accounting Standards The Company has adopted the following new accounting standards that have been recently issued: Business Combinations In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-08, Business Combinations: Accounting for Contract Asset and Contract Liabilities from Contracts with Customers, which requires that an acquirer in a business combination recognize and measure contract assets and liabilities acquired in accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("Topic 606") as if the acquirer had originated the contracts. The Company early adopted the ASU effective January 1, 2022, with no impact to its financial statements and related disclosures. Government Assistance In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance , which requires certain disclosures when companies have received government assistance and use a grant or contribution accounting model by analogy to other accounting guidance. A company that has received government assistance must provide disclosures related to the nature of the transaction, accounting policies used to account for the transaction, and the amounts and financial statement line items that are affected by the transaction. The Company prospectively adopted the ASU effective January 1, 2022, with no impact to its financial statements and related disclosures. Fair Value Measurement In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , which clarifies that a company should not consider contractual restrictions on the sale of equity securities in measuring fair value. This ASU clarifies the guidance in ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), on the fair value measurement of equity securities that are subject to a contractual sale restriction and requires specific disclosures related to such equity securities. The Company early adopted this ASU effective July 1, 2022, with no impact to its financial statements and related disclosures.

Segment Data

Segment Reporting [Abstract]
Segment Data	Note 3: Segment Data The Company reports its operations through the following segments: (1) Americas, (2) Europe, Middle East and Africa ("EMEA") and (3) Asia Pacific ("APAC"). The Americas consists of operations located in the United States, Canada and key markets in Latin America. EMEA includes operations in the U.K., France, Netherlands and other markets in Europe and the Middle East. APAC includes operations in Australia, Singapore, China and other markets in the Asia Pacific region. Adjusted EBITDA is the profitability metric reported to the chief operating decision maker (“CODM”) for purposes of making decisions about allocation of resources to each segment and assessing performance of each segment. The Company believes that investors find this measure useful in comparing our operating performance to that of other companies in our industry because this measure generally illustrates the underlying performance of the business before integration and other costs related to merger, pre-IPO stock-based compensation, unrealized (gains) / losses on investments, acquisition related costs and efficiency initiatives, and other items. Adjusted EBITDA also excludes the effects of financings, income tax and the non-cash accounting effects of depreciation and intangible asset amortization. As segment assets are not reported to or used by the CODM to measure business performance or allocate resources, total segment assets and capital expenditures are not presented below. Summarized financial information by segment is as follows (in millions): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 % Change 2022 2021 % Change Total revenue Americas $ 2,011.4 $ 1,680.2 20 % $ 3,796.8 $ 3,105.1 22 % EMEA 271.9 264.1 3 % 509.5 488.0 4 % APAC 329.3 304.0 8 % 637.3 579.0 10 % Total revenue $ 2,612.6 $ 2,248.3 16 % $ 4,943.6 $ 4,172.1 18 % Adjusted EBITDA Americas $ 210.5 $ 157.1 34 % $ 386.5 $ 234.9 65 % EMEA 35.3 31.9 11 % 52.0 34.3 52 % APAC 17.0 30.9 (45) % 38.6 50.4 (23) % Adjusted EBITDA is calculated as follows (in millions): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Adjusted EBITDA - Americas $ 210.5 $ 157.1 $ 386.5 $ 234.9 Adjusted EBITDA - EMEA 35.3 31.9 52.0 34.3 Adjusted EBITDA - APAC 17.0 30.9 38.6 50.4 Add/(less): Depreciation and amortization (39.7) (42.5) (80.3) (85.6) Interest expense, net of interest income (46.1) (43.8) (89.3) (86.2) Provision for income taxes (25.8) (43.2) (56.4) (15.2) Unrealized (loss) gain on investments, net (27.3) 6.1 (48.8) 6.1 Integration and other costs related to merger (4.3) (5.6) (7.9) (21.8) Pre-IPO stock-based compensation (1.0) (1.5) (1.7) (3.1) Acquisition related costs and efficiency initiatives (17.8) (33.3) (35.0) (73.5) Other (3.6) (3.4) (15.0) (4.8) Net income $ 97.2 $ 52.7 $ 142.7 $ 35.5

The Company had no material asset impairment charges related to contract assets in the periods presented. As of June 30, 2022 and December 31, 2021, the Company had contract liabilities of $48.0 million and $62.8 million, respectively, which were recorded in Accounts payable and accrued expenses in the Condensed Consolidated Balance Sheets, respectively. Exemptions The Company incurs incremental costs to obtain new contracts across certain of its service lines. As the amortization period of those expenses is 12 months or less, the Company expenses those incremental costs of obtaining the contracts in accordance with Topic 606. Remaining performance obligations represent the aggregate transaction prices for contracts where the performance obligations have not yet been satisfied. In accordance with Topic 606, the Company does not disclose unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) variable consideration for services performed as a series of daily performance obligations, such as those performed within the Property, facilities and project management service line. Performance obligations within these businesses represent a significant portion of the Company's contracts with customers not expected to be completed within 12 months.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Hedging Activities	Note 7: Derivative Financial Instruments and Hedging Activities The Company is exposed to certain risks arising from both business operations and economic conditions, including interest rate risk and foreign exchange risk. To mitigate the impact of interest rate and foreign exchange risk, the Company enters into derivative financial instruments. The Company maintains the majority of its overall interest rate exposure on floating rate borrowings to a fixed-rate basis, primarily with interest rate swap agreements. The Company manages exposure to foreign exchange fluctuations primarily through short-term forward contracts. There have been no significant changes to the interest rate and foreign exchange risk management objectives from those disclosed in the Company’s audited Consolidated Financial Statements for the year ended December 31, 2021. Interest Rate Derivative Instruments As of June 30, 2022, the Company's active interest rate hedging instruments consist of five interest rate swap agreements designated as cash flow hedges. The Company's hedge instrument balances as of June 30, 2022 relate solely to these interest rate swaps. The hedge instruments expire in August 2025 and are further described below. The Company records changes in the fair value of derivatives designated and qualifying as cash flow hedges in Accumulated other comprehensive loss in the Condensed Consolidated Balance Sheets and subsequently reclassifies the changes into earnings in the period that the hedged forecasted transaction affects earnings. As of June 30, 2022 and December 31, 2021, there were $7.9 million in pre-tax gains and $83.6 million in pre-tax losses, respectively, included in Accumulated other comprehensive loss related to these agreements, which will be reclassified to Interest expense, net of interest income as interest payments are made in accordance with the 2018 Credit Agreement; refer to Note 8: Long-Term Debt and Other Borrowings for discussion of this agreement. During the next twelve months, the Company estimates that $4.1 million will be reclassified to Interest income in the Condensed Consolidated Statements of Operations. Non-designated Foreign Exchange Derivative Instruments Additionally, the Company enters into short-term forward contracts to mitigate the risk of fluctuations in foreign currency exchange rates that would adversely impact some of the Company’s foreign currency denominated transactions. Hedge accounting was not elected for any of these contracts. As such, changes in the fair value of these contracts are recorded directly in earnings. The Company recognized realized losses of $5.3 million, offset by unrealized gains of $4.0 million during the three months ended June 30, 2022; and realized losses of $11.2 million, offset by unrealized gains of $9.6 million during the six months ended June 30, 2022, related to these foreign currency forward contracts. No material net fair value gains or losses were recorded for the three and six months ended June 30, 2021. As of June 30, 2022 and December 31, 2021, the Company had 23 and 19 foreign currency exchange forward contracts outstanding covering a notional amount of $732.3 million and $642.7 million, respectively. As of June 30, 2022 and December 31, 2021, the Company has not posted and does not hold any collateral related to these agreements. The following table presents the fair value of derivatives as of June 30, 2022 and December 31, 2021 (in millions): June 30, 2022 December 31, 2021 June 30, 2022 Assets Liabilities Assets Liabilities Derivative Instrument Notional Fair Value Fair Value Fair Value Fair Value Designated: Cash flow hedges: Interest rate swaps $ 1,423.6 $ 7.9 $ — $ — $ 84.0 Non-designated: Foreign currency forward contracts 732.3 1.2 0.8 0.9 1.1 The fair value of interest rate swaps is included within Other non-current assets as of June 30, 2022 and Other non-current liabilities as of December 31, 2021 in the Condensed Consolidated Balance Sheets.

On January 20, 2020, the Company refinanced the 2018 First Lien Loan under materially the same terms, incurring an additional $11.1 million in debt transaction costs. The 2018 First Lien Loan matures on August 21, 2025. The 2018 First Lien Loan bears interest at a variable interest rate that the Company may select per the terms of the 2018 Credit Agreement. As of June 30, 2022, the rate is equal to 1-month LIBOR plus 2.75%. As of June 30, 2022, the effective interest rate of the 2018 First Lien Loan was 4.70%. The 2018 First Lien Loan requires quarterly principal payments equal to 0.25% of the aggregate principal amount of the 2018 First Lien Loan, including incremental borrowings. Revolver On December 20, 2019, the Company amended the 2018 Credit Agreement to increase the aggregate commitments under the Revolver by $210.0 million, incurring an additional $0.5 million in debt transaction costs. On April 28, 2022, the Company amended the 2018 Credit Agreement to (i) increase the aggregate commitments under the Revolver by $80.0 million, extending its borrowing capacity from $1.0 billion to $1.1 billion, (ii) extended the maturity date from August 21, 2023 to April 28, 2027, (iii) replaced the LIBOR rate with Term SOFR plus an applicable rate, and (iv) added incentives linked to sustainability features based on our greenhouse gas emission targets. The Company incurred an additional $3.7 million in debt transaction costs in connection with this amendment. Borrowings under the Revolver, if any, bear interest at our option, at rates varying from 1.75% to 2.75% based on achievement of certain Net Leverage Ratios (as defined in the 2018 Credit Agreement). The Company’s Revolver was undrawn as of June 30, 2022 and December 31, 2021. Financial Covenant and Terms The 2018 Credit Agreement has a springing financial covenant, tested on the last day of each fiscal quarter if the outstanding loans under the Revolver exceed an applicable threshold. If the financial covenant is triggered, the Net Leverage Ratio is tested for compliance not to exceed 5.00 to 1.00. The Company was in compliance with all of the covenants under the 2018 Credit Agreement as of June 30, 2022 and December 31, 2021. 2020 Senior Secured Notes On May 22, 2020, the Company issued $650.0 million of senior secured notes due May 15, 2028 (the "2020 Notes"). Net proceeds from the 2020 Notes were $638.5 million, consisting of a $650.0 million aggregate principal amount less $11.5 million from issuance costs. The 2020 Notes were offered in a private placement exempt from registration under the U.S. Securities Act of 1933, as amended. The 2020 Notes bear interest at a fixed rate of 6.75% and yielded an effective interest rate of 7.00% as of June 30, 2022.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9: Commitments and Contingencies Guarantees The Company’s guarantees primarily relate to requirements under certain client service contracts and have arisen through the normal course of business. These guarantees, with certain financial institutions, have both open and closed-ended terms, with remaining closed-ended terms up to 7.0 years and maximum potential future payments of approximately $47.8 million in the aggregate. None of these guarantees are individually material to the Company’s operating results, financial position or liquidity. The Company considers the future payment or performance related to non-performance under these guarantees to be remote. Contingencies In the normal course of business, the Company is subject to various claims and litigation. Many of these claims are covered under the Company’s current insurance programs, subject to self-insurance levels and deductibles. The Company is also subject to threatened or pending legal actions arising from activities of contractors. Such liabilities include the potential costs to settle litigation. A liability is recorded for the potential costs of carrying out further works based on known claims and previous claims history, and for losses from litigation that are probable and estimable. A liability is also recorded for the Company’s incurred but not reported ("IBNR") claims, based on assessment using prior claims history. Claims liabilities are presented as Other current liabilities and Other non-current liabilities in the Condensed Consolidated Balance Sheets. As of June 30, 2022 and December 31, 2021, contingent liabilities recorded within Other current liabilities were $145.0 million and $106.5 million, respectively, and contingent liabilities recorded within Other non-current liabilities were $22.6 million and $19.5 million, respectively. These contingent liabilities are made up of errors and omissions ("E&O") claims, workers’ compensation insurance liabilities and other claims and contingent liabilities. At June 30, 2022 and December 31, 2021, E&O and other claims were $50.0 million and $40.2 million, respectively, and workers’ compensation liabilities were $117.6 million and $85.8 million, respectively, included within Other current liabilities and Other non-current liabilities in the Condensed Consolidated Balance Sheets. The ultimate settlement of these matters may result in payments materially in excess of the amounts recorded due to their contingent nature and the inherent uncertainties of settlement proceedings. The Company had insurance recoverable balances for E&O claims as of June 30, 2022 and December 31, 2021 totaling $9.0 million and $6.3 million, respectively.

Fair Value Measurements

Fair Value Measurements	6 Months Ended
	Jun. 30, 2022
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 11: Fair Value Measurements The Company measures certain assets and liabilities in accordance with ASC 820, which defines fair value as the price that would be received for an asset, or paid to transfer a liability, in an orderly transaction between market participants on the measurement date. In addition, ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value as follows: • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2: inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices); and • Level 3: inputs for the asset or liability that are based on unobservable inputs in which there is little or no market data. There were no significant transfers between the three levels of the fair value hierarchy for the three and six months ended June 30, 2022 and or year ended December 31, 2021. There have been no significant changes to the valuation techniques and inputs used to develop the recurring fair value measurements from those disclosed in the Company's audited Consolidated Financial Statements for the year ended December 31, 2021. Financial Instruments The Company's financial instruments include cash and cash equivalents, trade and other receivables, deferred purchase price receivable ("DPP"), restricted cash, accounts payable and accrued expenses, short-term borrowings, long-term debt, interest rate swaps and foreign exchange contracts. The carrying amount of cash and cash equivalents approximates the fair value of these instruments. Certain money market funds in which the Company has invested are highly liquid and considered cash equivalents. These funds are valued at the per unit rate published as the basis for current transactions. The estimated fair value of external debt was $3.1 billion and $3.3 billion as of June 30, 2022 and December 31, 2021, respectively. These instruments were valued using dealer quotes that are classified as Level 2 inputs in the fair value hierarchy. The gross carrying value of the debt was $3.3 billion and $3.3 billion as of June 30, 2022 and December 31, 2021, respectively, which excludes debt issuance costs. See Note 8: Long-Term Debt and Other Borrowings for additional information. The estimated fair value of interest rate swaps and foreign currency forward contracts are determined based on the expected cash flows of each derivative. The valuation method reflects the contractual period and uses observable market-based inputs, including interest rate and foreign currency forward curves. Investments in Real Estate Ventures The Company directly invests in early stage proptech companies, real estate venture capital funds, and other real estate companies across various sectors. The Company typically reports these investments at cost, less impairment charges, and adjusts to fair value if the Company identifies observable price changes in orderly transactions for identical or similar instruments of the same issuer. Investments in early stage proptech companies or other real estate companies are typically fair valued as a result of pricing observed in subsequent funding rounds. These investments are not fair valued on a recurring basis and as such have been excluded from the fair value hierarchy table. As of June 30, 2022 and December 31, 2021, investments in early stage proptech companies had a fair value of approximately $32.0 million and $24.0 million, respectively, included in Other non-current assets in the Condensed Consolidated Balance Sheets. In October 2021, the Company made a strategic investment of $150.0 million in WeWork, which is accounted for as an investment in equity securities reported at fair value, included in Other non-current assets in the Condensed Consolidated Balance Sheets. As quoted market prices for identical assets are available, this investment is classified as a Level 1 investment, and mark to market gains and losses are recognized on a recurring basis. Investments in real estate venture capital funds are fair valued using the net asset value ("NAV") per share (or its equivalent) provided by investees. Critical inputs to NAV estimates include valuations of the underlying real estate assets and borrowings, which incorporate investment-specific assumptions such as discount rates, capitalization rates, rental and expense growth rates, and asset-specific market borrowing rates. As these investments are not required to be classified in the fair value hierarchy, they have been excluded from the fair value hierarchy table. As of June 30, 2022 and December 31, 2021, investments in real estate venture capital funds had a fair value of approximately $66.3 million and $54.1 million, respectively, included in Other non-current assets in the Condensed Consolidated Balance Sheets. The Company adjusts these investments to their fair values each reporting period, and the changes are reflected in Other (expense) income, net, in the Condensed Consolidated Statements of Operations. During the three months ended June 30, 2022, the Company recognized an unrealized loss of $27.0 million related to our investment in WeWork, and immaterial losses from other fair value investments. During the six months ended June 30, 2022, the Company recognized an unrealized loss of $53.7 million related to our investment in WeWork, offset by unrealized gains of $4.9 million from other fair value investments. During the three and six months ended June 30, 2021, the Company recognized an unrealized gain of $6.1 million from other fair value investments. Recurring Fair Value Measurements The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021 (in millions): As of June 30, 2022 Total Level 1 Level 2 Level 3 Assets Cash equivalents - money market funds $ 0.9 $ 0.9 $ — $ — Deferred compensation plan assets 31.9 31.9 — — Foreign currency forward contracts 1.2 — 1.2 — Interest rate swap agreements 7.9 — 7.9 — Deferred purchase price receivable 88.9 — — 88.9 Equity securities 75.3 75.3 — — Total $ 206.1 $ 108.1 $ 9.1 $ 88.9 Liabilities Deferred compensation plan liabilities $ 32.7 $ 32.7 $ — $ — Foreign currency forward contracts 0.8 — 0.8 — Earn-out liabilities 24.1 — — 24.1 Total $ 57.6 $ 32.7 $ 0.8 $ 24.1 As of December 31, 2021 Total Level 1 Level 2 Level 3 Assets Cash equivalents - money market funds $ 45.2 $ 45.2 $ — $ — Deferred compensation plan assets 47.2 47.2 — — Foreign currency forward contracts 0.9 — 0.9 — Deferred purchase price receivable 142.3 — — 142.3 Equity securities 129.0 129.0 — — Total 364.6 221.4 0.9 142.3 Liabilities Deferred compensation plan liabilities $ 47.4 $ 47.4 $ — $ — Foreign currency forward contracts 1.1 — 1.1 — Interest rate swap agreements 84.0 — 84.0 — Earn-out liabilities 21.4 — — 21.4 Total $ 153.9 $ 47.4 $ 85.1 $ 21.4 Deferred Compensation Plans Prior to 2017, the Company provided deferred compensation plans to certain U.S. employees whereby the employee could defer a portion of employee compensation, which the Company would hold in trust, enabling the employees to defer tax on compensation until payment is made to them from the trust. These plans are frozen. The employees continue to be at risk for any investment fluctuations of the funds held in trust. The Company adopted a new deferred compensation plan, which become effective on January 1, 2019. The plan allows highly-compensated employees to defer a portion of compensation, enabling the employee to defer tax on compensation until payment is made. Deferred compensation is credited into an account denominated in ordinary shares of the Company in a number determined based on the fair market value of the Company’s ordinary shares on the date of the deposit. All payments are made in ordinary shares. The fair value of assets and liabilities of these plans is based on the value of the underlying investments using quoted prices in active markets at period end. Deferred compensation plan assets are presented within Prepaid expenses and other current assets and Other non-current assets in the Condensed Consolidated Balance Sheets. Deferred compensation liabilities are presented within Accrued compensation and Other non-current liabilities in the Condensed Consolidated Balance Sheets. Foreign Currency Forward Contracts and Interest Rate Swap Agreements Refer to Note 7: Derivative Financial Instruments and Hedging Activities for discussion of the fair value associated with these derivative assets and liabilities. Deferred Purchase Price Receivable The Company recorded a DPP under its Accounts Receivable ("A/R") Securitization program upon the initial sale of trade receivables. The DPP represents the difference between the fair value of the trade receivables sold and the cash purchase price and is recognized at fair value as part of the sale transaction. The DPP is subsequently remeasured each reporting period in order to account for activity during the period, such as the seller’s interest in any newly transferred receivables, collections on previously transferred receivables attributable to the DPP and changes in estimates for credit losses. Changes in the DPP attributed to changes in estimates for credit losses are expected to be immaterial, as the underlying receivables are short-term and of high credit quality. The DPP is included in Other non-current assets in the Condensed Consolidated Balance Sheets and is valued using unobservable inputs (i.e., Level 3 inputs), primarily discounted cash flows. Refer to Note 12: Accounts Receivable Securitization for more information. Earn-out Liabilities The Company has various contractual obligations associated with the acquisition of several real estate service companies in the United States, Australia, Canada and Europe, including contingent consideration, comprised of earn-out payments to the sellers subject to achievement of certain performance criteria in accordance with the terms and conditions set forth in the purchase agreements. An increase to a probability of achievement would result in a higher fair value measurement. The amounts disclosed in the table above are included in Other current liabilities and Other non-current liabilities in the Condensed Consolidated Balance Sheets. As of June 30, 2022, the Company had the potential to make a maximum of $29.2 million and a minimum of $0.0 million (undiscounted) in earn-out payments. Assuming the achievement of the applicable performance criteria, these earn-out payments will be made over the next five years. Earn-out liabilities are classified within Level 3 in the fair value hierarchy because the methodology used to develop the estimated fair value includes significant unobservable inputs reflecting management’s own assumptions. The fair value of earn-out liabilities is based on the present value of probability-weighted expected return method related to the earn-out performance criteria on each reporting date. The probabilities of achievement assigned to the performance criteria are determined based on due diligence performed at the time of acquisition as well as actual performance achieved subsequent to acquisition. Adjustments to the earn-out liabilities in periods subsequent to the completion of acquisitions are reflected within Operating, administrative and other in the Condensed Consolidated Statements of Operations. The table below presents a reconciliation of earn-out liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in millions): Earn-out Liabilities 2022 2021 Balance as of January 1, $ 21.4 $ 21.0 Purchases/additions 3.4 — Net change in fair value and other adjustments (0.6) (0.4) Payments (0.1) (0.8) Balance as of June 30, $ 24.1 $ 19.8

Transfers and Servicing [Abstract]
Accounts Receivable Securitization	Note 12: Accounts Receivable Securitization The Company's A/R Securitization has an investment limit of $125.0 million and terminates on August 20, 2022. Under the A/R Securitization, certain of the Company’s wholly owned subsidiaries continuously sell (or contribute) receivables to certain wholly owned special purpose entities at fair market value. The special purpose entities then sell 100% of the receivables to an unaffiliated financial institution (the "Purchaser”). Although the special purpose entities are wholly owned subsidiaries of the Company, they are separate legal entities with their own separate creditors who will be entitled, upon their liquidation, to be satisfied out of their assets prior to any assets or value in such special purpose entities becoming available to their equity holders and their assets are not available to pay other creditors of the Company. As of June 30, 2022 and December 31, 2021 the Company had $80.0 million and $0.0 million, respectively, drawn on the investment limit. All transactions under the A/R Securitization are accounted for as a true sale in accordance with ASC 860, Transfers and Servicing ("Topic 860"). Following the sale and transfer of the receivables to the Purchaser, the receivables are legally isolated from the Company and its subsidiaries, and the Company sells, conveys, transfers and assigns to the Purchaser all its rights, title and interest in the receivables. Receivables sold are derecognized from the statement of financial position. The Company continues to service, administer and collect the receivables on behalf of the Purchaser, and recognizes a servicing liability in accordance with Topic 860. Any financial statement impact associated with the servicing liability was immaterial for all periods presented. This program allows the Company to receive a cash payment and a DPP for sold receivables. The DPP is paid to the Company in cash on behalf of the Purchaser as the receivables are collected; however, due to the revolving nature of the A/R Securitization, cash collected from the Company’s customers is reinvested by the Purchaser daily in new receivable purchases under the A/R Securitization. For the six months ended June 30, 2022 and 2021, receivables sold under the A/R securitization were $674.6 million and $627.6 million, respectively, and cash collections from customers on receivables sold were $651.3 million and $639.4 million, respectively, all of which were reinvested in new receivables purchases and are included in cash flows from operating activities in the Condensed Consolidated Statements of Cash Flows. As of June 30, 2022 and December 31, 2021, the outstanding principal on receivables sold under the A/R Securitization was $182.0 million and $158.7 million, respectively. Refer to Note 11: Fair Value Measurements for additional discussion on the fair value of the DPP as of June 30, 2022 and December 31, 2021.

Accounting Policies [Abstract]
New Accounting Standards	The Company has adopted the following new accounting standards that have been recently issued: Business Combinations In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-08, Business Combinations: Accounting for Contract Asset and Contract Liabilities from Contracts with Customers, which requires that an acquirer in a business combination recognize and measure contract assets and liabilities acquired in accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("Topic 606") as if the acquirer had originated the contracts. The Company early adopted the ASU effective January 1, 2022, with no impact to its financial statements and related disclosures. Government Assistance In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance , which requires certain disclosures when companies have received government assistance and use a grant or contribution accounting model by analogy to other accounting guidance. A company that has received government assistance must provide disclosures related to the nature of the transaction, accounting policies used to account for the transaction, and the amounts and financial statement line items that are affected by the transaction. The Company prospectively adopted the ASU effective January 1, 2022, with no impact to its financial statements and related disclosures. Fair Value Measurement In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , which clarifies that a company should not consider contractual restrictions on the sale of equity securities in measuring fair value. This ASU clarifies the guidance in ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), on the fair value measurement of equity securities that are subject to a contractual sale restriction and requires specific disclosures related to such equity securities. The Company early adopted this ASU effective July 1, 2022, with no impact to its financial statements and related disclosures.
