Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Si gnificant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, the unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The accounting policies we follow are set forth in Note 2, “Summary of Significant Accounting Policies,” to our audited consolidated financial statements in our 2021 Form 10-K . The following notes should be read in conjunction with these policies and other disclosures in our 2021 Form 10-K. In the opinion of management, the unaudited condensed consolidated financial statements contained herein reflect all adjustments (consisting only of normal recurring adjustments, except as set forth in these notes to condensed consolidated financial statements) necessary to present fairly in all material aspects the financial position, results of operations, comprehensive income (loss), and cash flows from all periods presented. Interim results are not necessarily indicative of results for a full year. Deferred Costs Deferred costs, which primarily consist of deferred sales commissions, included within Other assets on our condensed consolidated balance sheets were $ 141.6 million and $ 144.5 million as of June 30, 2022, and December 31, 2021 , respectively. Amortization expense for the deferred costs was $ 12.8 million and $ 11.3 million for the three months ended June 30, 2022, and 2021 , respectively, and $ 25.4 million and $ 22.3 million for the six months ended June 30, 2022, and 2021 , respectively. Recently Issued and Adopted Accounting Pronouncements from the Financial Accounting Standards Board Standard Issuance Date Description Adoption Date Effect on the Financial Statements Accounting Standards Update ("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) August 2020 This amendment simplifies the accounting for convertible instruments by removing certain separation models required under current GAAP for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost. January 2022 We adopted the guidance as of January 1, 2022 , using the modified retrospective method of transition. The adoption resulted in the elimination of the debt discount (and related deferred tax liability) that was recorded within equity related to our Convertible Senior Notes. The net impact of the adjustments was recorded to the opening balance of accumulated deficit and additional paid in capital. The impact to the condensed consolidated balance sheet was as follows: (1) increase of $ 92.9 million to long-term debt, (2) decrease of $ 77.7 million to additional paid-in capital, net of allocated issuance costs of $ 2.7 million and deferred tax impact of $ 28.2 million, and (3) decrease to accumulated deficit of $ 10.0 million. ASU 2020-04 , Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting March 2020 This amendment provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Not yet adopted This amendment may be elected over time through December 31, 2022 as reference rate reform activities occur. We do not expect the adoption of this guidance to have a significant impact on our financial statements.

(b) For the contingent consideration related to the 2021 acquisition of certain assets and liabilities of DataFuzion HCM, Inc. ("DataFuzion"), we utilize an option pricing model, specifically a Black-Scholes-Merton model, to estimate the fair value of the contingent liability as of the reporting dates. This model uses certain assumptions related to risk-free rates and volatility as well as certain judgments in forecasting annual recurring revenue. The contingent consideration has been measured as Level 3 given the unobservable inputs that are significant to the measurement of liability. The contingent consideration is included within other liabilities in our condensed consolidated balance sheets. During the three and six months ended June 30, 2022 we recognized expense of $ 1.2 million and $ 2.0 million, respectively, within selling, general, and administrative expense in our condensed consolidated statements of operations due to the remeasurement of the DataFuzion contingent consideration. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis During the six months ended June 30, 2022 , we did not re-measure any financial assets or liabilities at fair value on a nonrecurring basis. During the year ended December 31, 2021, assets and liabilities acquired as part of business combinations and recognized as part of our convertible debt issuance have been recorded at fair value on a nonrecurring basis.

Customer Funds	5. Customer Funds In certain jurisdictions, we collect funds for payment of payroll and taxes; temporarily hold such funds until payment is due; remit the funds to the clients’ employees and appropriate taxing authorities; file federal, state, and local tax returns; and handle related regulatory correspondence and amendments. The customer assets are held in segregated accounts intended for the specific purpose of satisfying client fund obligations and therefore are not freely available for our general business use. In the U.S. and Canada, these customer funds are held in trusts. Investment income from invested customer funds, also referred to as float revenue or float, is a component of our compensation for providing services under agreements with our customers. Investment income from invested customer funds included in recurring revenue was $ 14.7 million and $ 10.4 million for the three months ended June 30, 2022, and 2021, respectively, and $ 26.1 million and $ 21.1 million for the six months ended June 30, 2022, and 2021.

We continue to evaluate the use of our trade names and branding in our sales and marketing efforts. If there is a fundamental shift in the method of our branding in the future, we will assess the impact on the carrying amount of our trade name intangible assets to determine whether an impairment exists. If it is determined that an impairment has occurred, it would be recognized during the period in which the decision was made to make the fundamental shift. Amortization expense related to definite-lived intangible assets was $ 7.6 million and $ 9.8 million for the three months ended June 30, 2022, and 2021 , respectively, and $ 15.4 million and $ 12.0 million for the six months ended June 30, 2022, and 2021 respectively.

Debt	7. D ebt Overview Our debt obligations consisted of the following as of the periods presented: June 30, December 31, 2022 2021 (Dollars in millions) Term Debt, interest rate of 4.2 % and 2.6 %, respectively $ 654.5 $ 657.9 Revolving Credit Facility ($ 300.0 million available capacity less amounts reserved for 2.1 million) — — Convertible Senior Notes, interest rate of 0.25 % 575.0 575.0 Australia Line of Credit (AUD $ 1.5 million letter of credit capacity, which was fully utilized; USD $ 1.0 million) — — Financing lease liabilities (Please refer to Note 13) 9.0 9.6 Total debt 1,238.5 1,242.5 Less unamortized discount on Term Debt and Convertible Senior Notes (a) 0.8 95.5 Less unamortized debt issuance costs on Term Debt and Convertible Senior Notes (a) 14.7 14.3 Less current portion of long-term debt 8.3 8.3 Long-term debt, less current portion $ 1,214.7 $ 1,124.4 a) We adopted ASU 2020-06 as of January 1, 2022. The unamortized discount and debt issuance costs on the Convertible Senior Notes is presented post-adoption of ASU 2020-06 as of June 30, 2022 and is presented pre-adoption of ASU 2020-06 as of December 31, 2021. Refer to the Convertible Senior Notes section below for further discussion of the impacts of the adoption of ASU 2020-06 on our condensed consolidated financial statements. Accrued interest and fees related to the debt obligati ons was $ 0.5 million as of June 30, 2022 and December 31, 2021, and is included within Other accrued expenses in our condensed consolidated balance sheets. Senior Secured Credit Facility On April 30, 2018, we completed the refinancing of our debt by entering into a new credit agreement. Pursuant to the terms of the new credit agreement, we became borrower of (i) a $ 680.0 million term loan debt facility (the “Term Debt”) and (ii) a $ 300.0 million revolving credit facility (the “Revolving Credit Facility”) (collectively, the “Senior Secured Credit Facility”). Our obligations under the Senior Secured Credit Facility are secured by first priority security interests in substantially all of our assets and the domestic subsidiary guarantors, subject to permitted liens and certain exceptions. The Term Debt will mature on April 30, 2025 . We are required to make annual amortization payments in respect of the Term Debt in an amount equal to 1.00 % of the original principal amount thereof, payable in equal quarterly installments of 0.25 % of the original principal amount of the first lien term debt. On December 15, 2021, we completed the second amendment to our Senior Secured Credit Facility, which extended that maturity date of the Revolving Credit Facility from April 30, 2023 to January 29, 2025 . The Revolving Credit Facility does not require amortization payments. Convertible Senior Notes In March 2021, we issued $ 575.0 million in aggregate principal amount of 0.25 % Convertible Senior Notes due 2026 in a private offering to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act of 1933, as amended, and pursuant to exemptions from the prospectus requirements of applicable Canadian securities laws, including the exercise in full by the initial purchasers of their option to purchase an additional $ 75.0 million in aggregate principal amount of 0.25 % Convertible Senior Notes due 2026 (collectively, the “Convertible Senior Notes”). The Convertible Senior Notes bear interest at a rate of 0.25 % per year and interest is payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021 . The Convertible Senior Notes mature on March 15, 2026 , unless earlier converted, redeemed or repurchased. The total net proceeds from the offering, after deducting initial purchase discounts and other debt issuance costs, were $ 561.8 million. The following table presents details of the Convertible Senior Notes: Initial Conversion Rate per $ 1,000 Principal Initial Conversion Price per Share Convertible Senior Notes 7.5641 shares $ 132.20 The Convertible Senior Notes will be convertible at the option of the holders at any time only under certain circumstances as outlined in Note 9, “Debt,” to our audited consolidated financial statements in our 2021 Form 10-K . The conditions allowing holders of the Convertible Senior Notes to convert have not been met and therefore were not convertible as of June 30, 2022. On December 30, 2021, we notified the holders of the Convertible Senior Notes of our irrevocable election to settle the conversion obligation in connection with the Convertible Senior Notes submitted for conversion on or after January 1, 2022, or at maturity with a combination of cash and shares of our common stock. Generally, under this settlement method, the conversion value will be settled in cash in an amount no less than the principal amount being converted, and any excess of the conversion value over the principal amount will be settled, at our election, in cash or shares of common stock. On January 1, 2022, we adopted ASU 2020-06 using the modified retrospective transition method. Under such transition, prior-period information has not been retrospectively adjusted for this change in accounting guidance. Upon the adoption of ASU 2020-06, the Convertible Senior Notes are accounted for as a single liability, and the carrying amount of the Convertible Senior Notes was $ 564.0 million as of June 30, 2022 , with principal of $ 575.0 million, net of issuance costs of $ 11.0 million. The Convertible Senior Notes are included within Long-term debt, less current portion in our condensed consolidated balance sheets as of June 30, 2022 . The issuance costs related to the Convertible Senior Notes are being amortized to interest expense over the contractual term of the Convertible Senior Notes at an effective interest rate of 5.1 %. Interest expense recognized related to the Convertible Senior Notes was as follows: Three Months Ended June 30, 2022 Three Months Ended June 30, 2021 Six Months Ended June 30, 2022 Six Months Ended June 30, 2021 (Post-adoption of ASU 2020-06) (Pre-adoption of ASU 2020-06) (Post-adoption of ASU 2020-06) (Pre-adoption of ASU 2020-06) (Dollars in millions) Contractual interest expense $ 0.3 $ 0.4 $ 0.6 $ 0.5 Amortization of debt discount — 4.4 — 5.1 Amortization of debt issuance costs 0.7 0.5 1.4 0.6 Total $ 1.0 $ 5.3 $ 2.0 $ 6.2 Capped Calls In March 2021, in connection with the pricing of the Convertible Senior Notes, we entered into capped call transactions with the option counterparties (the “Capped Calls”). The Capped Calls each have an initial strike price of $ 132.20 per share, and an initial cap price of $ 179.26 per share, both subject to certain adjustments. The capped call transactions are generally expected to reduce potential dilution to our common stock upon any conversion of the Convertible Senior Notes and/or offset any potential cash payments we would be required to make in excess of the principal amount of converted Convertible Senior Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. For accounting purposes, the Capped Calls are separate transactions, and not part of the terms of the Convertible Senior Notes. As the Capped Calls qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer's own stock and classified in stockholder’s equity in our condensed consolidated balance sheet, we have recorded an amount of $ 33.0 million as a reduction to additional paid-in capital which will not be remeasured. This represents the premium of $ 45.0 million paid for the purchase of the Capped Calls, net of the deferred tax impact of $ 12.0 million. Future Payments and Maturities of Debt The future principal payments and maturities of our indebtedness, excluding financing lease obligations, are as follows: Years Ending December 31, Amount (Dollars in millions) 2022 $ 3.4 2023 6.8 2024 6.8 2025 637.5 2026 575.0 $ 1,229.5 Fair Value of Debt Our debt does not trade in active markets and was considered to be a Level 2 measurement at June 30, 2022 . The fair value of the Term Debt was based on the borrowing rates currently available to us for bank loans with similar terms and average maturities and the limited trades of our debt. The fair value of the Convertible Senior Notes was determined based on the closing trading price per $ 1,000 of the Convertible Senior Notes as of the last day of trading for the period and is primarily affected by the trading price of our common stock and market interest rates. The fair value of our debt was estimated to be $ 1,078.8 million and $ 1,248.9 million as of June 30, 2022, and December 31, 2021 , respectively.

Share-Based Compensation	9. Share-Based Compensation Our share-based compensation consists of stock options, restricted stock units (“RSU”), and performance-based stock units (“PSU”). We also offer an employee stock purchase plan. Under the 2013 Ceridian HCM Holding Inc. Stock Incentive Plan, as amended ("2013 SIP") and Ceridian HCM Holding Inc. 2018 Equity Incentive Plan (as amended and restated from time to time, the “2018 EIP”), we have shares reserved for issuance of common stock to eligible employees and our board of directors. The 2018 EIP serves as a successor to the 2013 SIP as we ceased granting awards under the 2013 SIP as of April 24, 2018, and we do not intend to grant any additional awards under the 2013 SIP. Most of our equity awards under the 2018 EIP vest either annually or quarterly on a pro rata basis, generally over a one -, three -, four -, or five-year period or on a specific date if certain performance criteria are satisfied and certain equity values are attained. In addition, upon termination of service, all vested awards must be exercised generally within 90 days after termination, or these awards will be forfeited. The equity awards have a 10 -year contractual term, and the options have an exercise price that is not less than the fair market value of the underlying stock on the date of grant. Pursuant to the evergreen refresh provision of the 2018 EIP, on February 23, 2022, the Board of Directors approved an increase to the share reserve of the three percent of the number of shares of common stock outstanding on January 31, 2022 to take place on March 31, 2022. Further, our Board of Directors approved an amendment effective April 1, 2022, to remove the evergreen refresh provision of the 2018 EIP that permitted the share reserve to be increased on March 31 of each of the first ten calendar years during the term of the 2018 EIP, by the lesser of (i) three percent of the number of shares of our common stock outstanding on each January 31 immediately prior to the date of increase or (ii) such number of shares of our common stock determined by the Board of Directors. As of June 30, 2022 , there were 946,948 stock options and RSUs outstanding under the 2013 SIP and there were 12,426,311 stock options, RSUs, and PSUs outstanding and 13,733,625 shares available for future grants of equity awards under the 2018 EIP. Total share-based compensation expense was $ 38.8 million and $ 31.4 million for the three months ended June 30, 2022, and 2021, respectively, and $ 74.3 million and $ 54.2 million for the six months ended June 30, 2022, and 2021.

One-third of the PSUs granted in 2021 as part of long term incentive grants to certain members of management vested on March 8, 2022 , and will vest on each of March 8, 2023 , and March 8, 2024 . On February 24, 2022, we granted PSUs under the 2022 Ceridian HCM Holding, Inc. Management Incentive Plan (the “2022 MIP”) for the incentive period of January 1, 2022 through December 31, 2022, and also as part of long term incentive grants to certain members of management. The vesting conditions for the PSUs granted on February 24, 2022, are based on the following performance criteria: (1) the Cloud revenue, excluding float revenue (the “Cloud Revenue Goal”) (2) the adjusted EBITDA, excluding float revenue (the “Adjusted EBITDA Goal”), and (3) the Sales per employee per month (“PEPM”) annual contract value (“ACV”) (the “Sales PEPM ACV Goal”), for fiscal year 2022 (collectively the “Performance Goals”). Both the Cloud Revenue Goal and the Adjusted EBITDA Goal are calculated based on our operating results on a constant currency basis as adjusted to exclude: float revenue; foreign exchange gain (loss); share-based compensation expense and related employer taxes; severance charges; restructuring consulting fees; significant acquisitions or disposals and related transaction costs; as well as other non-recurring items, subject to the Board of Directors approval. The Sales PEPM ACV Goal is calculated based on the sales of our solutions on a constant currency basis that contribute to Cloud recurring revenue. Any cash payment under the 2022 MIP and the vesting conditions for the PSU awards granted in 2022 will be determined based on our performance against the achievement of the Performance Goals, and the payout that a participant can receive may be between 0 % for not meeting the applicable thresholds of any of the Performance Goals, up to a maximum total payout of 167 % for achieving the maximum level of all of the Performance Goals. Upon vesting of a PSU, a participant will receive shares of common stock of the Company. The probability of vesting of the PSUs related to the 2022 MIP and as part of long term incentive grants to certain members of management will continue to be evaluated throughout 2022, and share-based compensation will be recognized in accordance with that probability. As of June 30, 2022 , there was $ 31.0 million of share-based compensation expense related to unvested PSUs not yet recognized.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes Our income tax provision represents federal, state, and international taxes on our income recognized for financial statement purposes and includes the effects of temporary differences between financial statement income and income recognized for tax return purposes. Deferred tax assets and liabilities are recorded for temporary differences between the financial reporting basis and the tax basis of assets and liabilities. We record a valuation allowance to reduce our deferred tax assets to reflect the net deferred tax assets that we believe will be realized. In assessing the likelihood that we will be able to recover our deferred tax assets and the need for a valuation allowance, we consider all available evidence, both positive and negative, including historical levels of pre-tax book income, expiration of net operating losses, changes in our debt and equity structure, expectations and risks associated with estimates of future taxable income, ongoing prudent and feasible tax planning strategies, as well as current tax laws. As of June 30, 2022 , we have a valuation allowance of $ 46.0 million against certain deferred tax assets consisting primarily of $ 13.2 million attributable to state net operating loss carryovers, and $ 31.0 million attributable to deferred tax assets recorded as part of a previous acquisition. We recorded an income tax expense of $ 3.8 million during the six months ended June 30, 2022 , consisting of tax expense of $ 6.3 million attributable to the global intangible low tax income ("GILTI") in the U.S, $ 5.9 million attributable to share-based compensation, and other tax expense of $ 0.7 million, partially offset by a $ 9.1 million tax benefit from current operations. There were no unrecognized tax benefits as of June 30, 2022, and December 31, 2021. We make adjustments to these reserves when facts and circumstances change, such as the closing of tax audits or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on our financial condition and operating results. We file income tax returns in the U.S. federal jurisdiction, various states, and foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2017.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	14. Commitments and Contingencies Legal Matters We are subject to claims and a number of judicial and administrative proceedings considered normal in the course of our current and past operations, including employment-related disputes, contract disputes, disputes with our competitors, intellectual property disputes, government audits and proceedings, customer disputes, and tort claims. In some proceedings, the claimant seeks damages as well as other relief, which, if granted, would require substantial expenditures on our part. Our general terms and conditions in customer contracts frequently include a provision indicating we will indemnify and hold our customers harmless from and against any and all claims alleging that the services and materials furnished by us violate any third party’s patent, trade secret, copyright, or other intellectual property right. We are not aware of any material pending litigation concerning these indemnifications. Some of these matters raise difficult and complex factual and legal issues and are subject to many uncertainties, including the facts and circumstances of each particular action, and the jurisdiction, forum, and law under which each action is proceeding. Because of these complexities, final disposition of some of these proceedings may not occur for several years. As such, we are not always able to estimate the amount of our possible future liabilities, if any. There can be no certainty that we may not ultimately incur charges in excess of presently established or future financial accruals or insurance coverage. Although occasional adverse decisions or settlements may occur, it is management’s opinion that the final disposition of these proceedings will not, considering the merits of the claims and available resources or reserves and insurance, and based upon the facts and circumstances currently known, have a material adverse effect on our financial position or results of operations.

Earnings Per Share [Abstract]
Net Loss per Share	15. Net Loss per Share We compute net loss per share of common stock using the treasury stock method. The basic and diluted net loss per share computations were calculated as follows: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 (Dollars in millions, except share and per share data) Numerator: Net loss $ ( 19.8 ) $ ( 25.8 ) $ ( 47.2 ) $ ( 45.0 ) Denominator: Weighted-average shares outstanding - basic 152,752,369 149,293,833 152,439,996 149,006,538 Effect of dilutive equity instruments — — — — Weighted-average shares outstanding - diluted 152,752,369 149,293,833 152,439,996 149,006,538 Net loss per share - basic $ ( 0.13 ) $ ( 0.17 ) $ ( 0.31 ) $ ( 0.30 ) Net loss per share - diluted $ ( 0.13 ) $ ( 0.17 ) $ ( 0.31 ) $ ( 0.30 ) The following potentially dilutive weighted-average shares were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Stock options 5,699,807 5,542,424 5,813,488 5,496,018 Restricted stock units 2,097,835 458,018 1,235,150 500,064 Performance stock units 1,439,481 729,104 1,340,950 667,903 The shares underlying the conversion option in the Convertible Senior Notes were not considered in the calculation of diluted net loss per share as the effect would have been anti-dilutive. Based on the initial conversion price, the entire outstanding principal amount of the Convertible Senior Notes as of June 30, 2022 would have been convertible into approximately 4.3 million shares of our common stock. Since we expect to settle the principal amount of the Convertible Senior Notes in cash, we use the treasury stock method for calculating any potential dilutive effect on diluted net income per share, if applicable. As a result, only the amount by which the conversion value exceeds the aggregate principal amount of the Convertible Senior Notes (the “conversion spread”) is considered in the diluted earnings per share computation. The conversion spread has a dilutive impact on diluted net income per share when the average market price of our common stock for a given period exceeds the initial conversion price of $ 132.20 per share for the Convertible Senior Notes. We excluded the potentially dilutive effect of the conversion spread of the Convertible Senior Notes as the average market price of our common stock during the three and six months ended June 30, 2022 was less than the conversion price of the Convertible Senior Notes. In connection with the issuance of the Convertible Senior Notes, we entered into Capped Calls, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, the unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The accounting policies we follow are set forth in Note 2, “Summary of Significant Accounting Policies,” to our audited consolidated financial statements in our 2021 Form 10-K . The following notes should be read in conjunction with these policies and other disclosures in our 2021 Form 10-K. In the opinion of management, the unaudited condensed consolidated financial statements contained herein reflect all adjustments (consisting only of normal recurring adjustments, except as set forth in these notes to condensed consolidated financial statements) necessary to present fairly in all material aspects the financial position, results of operations, comprehensive income (loss), and cash flows from all periods presented. Interim results are not necessarily indicative of results for a full year.
Deferred Costs	Deferred Costs Deferred costs, which primarily consist of deferred sales commissions, included within Other assets on our condensed consolidated balance sheets were $ 141.6 million and $ 144.5 million as of June 30, 2022, and December 31, 2021 , respectively. Amortization expense for the deferred costs was $ 12.8 million and $ 11.3 million for the three months ended June 30, 2022, and 2021 , respectively, and $ 25.4 million and $ 22.3 million for the six months ended June 30, 2022, and 2021 , respectively.
Recently Issued and Adopted Accounting Pronouncements from the Financial Accounting Standards Board	Recently Issued and Adopted Accounting Pronouncements from the Financial Accounting Standards Board Standard Issuance Date Description Adoption Date Effect on the Financial Statements Accounting Standards Update ("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) August 2020 This amendment simplifies the accounting for convertible instruments by removing certain separation models required under current GAAP for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost. January 2022 We adopted the guidance as of January 1, 2022 , using the modified retrospective method of transition. The adoption resulted in the elimination of the debt discount (and related deferred tax liability) that was recorded within equity related to our Convertible Senior Notes. The net impact of the adjustments was recorded to the opening balance of accumulated deficit and additional paid in capital. The impact to the condensed consolidated balance sheet was as follows: (1) increase of $ 92.9 million to long-term debt, (2) decrease of $ 77.7 million to additional paid-in capital, net of allocated issuance costs of $ 2.7 million and deferred tax impact of $ 28.2 million, and (3) decrease to accumulated deficit of $ 10.0 million. ASU 2020-04 , Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting March 2020 This amendment provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Not yet adopted This amendment may be elected over time through December 31, 2022 as reference rate reform activities occur. We do not expect the adoption of this guidance to have a significant impact on our financial statements.

(b) For the contingent consideration related to the 2021 acquisition of certain assets and liabilities of DataFuzion HCM, Inc. ("DataFuzion"), we utilize an option pricing model, specifically a Black-Scholes-Merton model, to estimate the fair value of the contingent liability as of the reporting dates. This model uses certain assumptions related to risk-free rates and volatility as well as certain judgments in forecasting annual recurring revenue. The contingent consideration has been measured as Level 3 given the unobservable inputs that are significant to the measurement of liability. The contingent consideration is included within other liabilities in our condensed consolidated balance sheets.

[1] Fair value is based on inputs that are observable for the asset or liability, other than quoted prices. For the contingent consideration related to the 2021 acquisition of certain assets and liabilities of DataFuzion HCM, Inc. ("DataFuzion"), we utilize an option pricing model, specifically a Black-Scholes-Merton model, to estimate the fair value of the contingent liability as of the reporting dates. This model uses certain assumptions related to risk-free rates and volatility as well as certain judgments in forecasting annual recurring revenue. The contingent consideration has been measured as Level 3 given the unobservable inputs that are significant to the measurement of liability. The contingent consideration is included within other liabilities in our condensed consolidated balance sheets.
