Business Combinations [Abstract]
Business Combinations	3. Business Combinations On February 1, 2024, we completed the purchase of 100 % of the outstanding shares of eloomi A/S ("eloomi"), a learning experience platform software provider based in Copenhagen, Denmark, and Orlando, Florida. The purchase accounting has not been finalized as of September 30, 2024 , with provisional amounts related to intangible assets, including goodwill, and tax positions. Intangible assets recorded for this acquisition consist of $ 85.2 million of developed technology and $ 1.8 million of customer relationships. The goodwill arising from the eloomi acquisition is primarily attributable to the potential to achieve synergies and other cost savings through integration with our existing operations. None of the goodwill associated with this acquisition is deductible for income tax purposes. The major classes of assets and liabilities to which we have preliminarily allocated the purchase price were as follows: (In millions) Cash and equivalents $ 6.5 Trade receivables, prepaid expenses, and other current assets 4.6 Goodwill 109.1 Other intangible assets 87.0 Other assets 0.6 Accounts payable and accrued liabilities ( 3.9 ) Deferred revenue ( 8.6 ) Deferred tax liability ( 15.7 ) Total purchase price $ 179.6

(b) For the contingent consideration related to the 2021 acquisition of certain assets and liabilities of DataFuzion HCM, Inc. ("DataFuzion"), we utilized a Monte Carlo simulation model to estimate the fair value of the contingent liability as of the reporting dates. As of December 31, 2023, our condensed consolidated balance sheet included $ 8.6 million within other accrued expenses and $ 6.3 million within other liabilities, respectively, related to this conti ngent consideration. Due to the remeasurement of the DataFuzion contingent consideration, we recognized expense of $ 9.0 million for the three and nine months ended September 30, 2024, and we recognized expense of $ 4.6 million and $ 11.8 million for the three and nine months ended September 30, 2023, respectively, within general and administrative expense in our condensed consolidated statements of operations. In August 2024, we made a payment of $ 23.9 million related to this liability. Financial Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis During the nine months ended September 30, 2024, assets acquired and liabilities assumed as part of the business combination and liabilities recognized as part of our debt issuance have been measured at fair value on a nonrecurring basis. During the year ended December 31, 2023 , we did not re-measure any financial assets or liabilities at fair value on a nonrecurring basis.

Customer Funds

Customer Funds	9 Months Ended
Customer Funds	Sep. 30, 2024
Investments, Debt and Equity Securities [Abstract]
Customer Funds	5. Cust omer Funds Overview 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 customers’ 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 customer funding 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. Our customer funds are held and invested with the primary objectives being to protect the principal balance and to ensure adequate liquidity to meet cash flow requirements. Accordingly, we maintain on average approximately 45 % to 55 % of customer funds in liquidity portfolios with maturities ranging from one to 120 days, consisting of high-quality bank deposits, money market mutual funds, commercial paper, or collateralized short-term investments; and we maintain on average approximately 45 % to 55 % of customer funds in fixed income portfolios with maturities ranging from 120 days to 10 years, consisting of U.S. Treasury and agency securities, Canada government and provincial securities, as well as highly rated asset-backed, mortgage-backed, municipal, corporate, and bank securities. To maintain sufficient liquidity to meet payment obligations, we also have financing arrangements and may pledge fixed income securities for short-term financing. Financial Statement Presentation 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 $ 45.6 million and $ 38.8 million for the three months ended September 30, 2024, and 2023, respectively, and $ 155.2 million and $ 127.5 million for nine months ended September 30, 2024, and 2023, respectively. Investment income includes interest income, realized gains and losses from sales of customer funds’ investments, and unrealized credit losses determined to be unrecoverable. The amortized cost of customer funds as of September 30, 2024, and December 31, 2023 , is the original cost of assets acquired. The amortized cost and fair values of investments of customer funds available for sale were as follows: September 30, 2024 Amortized Gross Unrealized Fair Cost Gain Loss Value (In millions) Money market securities, investments carried at cost $ 1,558.7 $ — $ — $ 1,558.7 Available for sale investments: U.S. government and agency securities 838.5 5.8 ( 20.3 ) 824.0 Canadian and provincial government securities 477.9 6.3 ( 4.4 ) 479.8 Corporate debt securities 745.2 11.5 ( 7.1 ) 749.6 Asset-backed securities 216.5 2.5 ( 1.0 ) 218.0 Mortgage-backed securities 68.3 1.8 ( 0.3 ) 69.8 Other short-term investments 3.7 — — 3.7 Other securities 73.1 0.4 ( 1.2 ) 72.3 Total available for sale investments 2,423.2 28.3 ( 34.3 ) 2,417.2 Invested customer funds 3,981.9 $ 28.3 $ ( 34.3 ) 3,975.9 Receivables 24.0 24.8 Total customer funds $ 4,005.9 $ 4,000.7 December 31, 2023 Amortized Gross Unrealized Fair Cost Gain Loss Value (In millions) Money market securities, investments carried at cost $ 2,800.7 $ — $ — $ 2,800.7 Available for sale investments: U.S. government and agency securities 768.3 2.3 ( 35.1 ) 735.5 Canadian and provincial government securities 448.7 1.3 ( 11.3 ) 438.7 Corporate debt securities 664.7 2.6 ( 19.4 ) 647.9 Asset-backed securities 208.9 1.0 ( 3.3 ) 206.6 Mortgage-backed securities 60.3 0.8 ( 0.7 ) 60.4 Other short-term investments 16.1 — — 16.1 Other securities 76.2 0.1 ( 3.2 ) 73.1 Total available for sale investments 2,243.2 8.1 ( 73.0 ) 2,178.3 Invested customer funds 5,043.9 $ 8.1 $ ( 73.0 ) 4,979.0 Receivables 49.6 49.6 Total customer funds $ 5,093.5 $ 5,028.6 The following represents the gross unrealized losses and the related fair value of the investments of customer funds available for sale, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position.

The unrealized losses are primarily attributable to changes in interest rates and not to credit deterioration. We currently do not intend to sell or expect to be required to sell the securities before the time required to recover the amortized cost. The amortized cost and fair value of investment securities available for sale at September 30, 2024, by contractual maturity are shown below.

Receivables Securitization Program In the third quarter of 2024, we entered into a receivables securitization program (the "Receivables Securitization Program") with MUFG Bank, Ltd. (“MUFG”), under which MUFG acts as an agent to facilitate the sale of certain Dayforce receivables (the “Receivables”) to MUFG and certain other investors from time-to-time unaffiliated with Dayforce (the “Purchasers”). The sale of these Receivables to the Purchasers is accounted for as a sale of assets under the provisions of Accounting Standards Codification ("ASC") 860, Transfers and Servicing, and as such the Receivables are derecognized from our condensed consolidated balance sheets. We continue to service any Receivables sold to the Purchasers. In connection with the Receivables Securitization Program, we sell certain trade and other receivables to special purpose entities (the “SPEs”), which are wholly-owned by Dayforce, which in turn sell a portion of these receivables to the Purchasers on a monthly basis. Per the terms of the Receivables Purchase Agreement (“RPA”) between us and MUFG entered into in connection with the Receivables Securitization Program, we may have a maximum of $ 150.0 million of accounts receivable sold to the Purchasers outstanding at any point in time. The portion of the receivables held by the SPEs, but not sold to the Purchasers, serve as collateral to the Purchasers on the sold Receivables, and are considered restricted accounts receivable. Cash receipts from the sale of Receivables to the Purchasers are reflected in net cash provided by operating activities in the condensed consolidated statements of cash flows. As of September 30, 2024, there was $ 210.9 million of restricted accounts receivable held by the SPEs that is reported within trade and other receivables, net on our condensed consolidated balance sheets. Of the Receivables sold to the Purchasers since the inception of the Receivables Securitization Program, $ 30.1 million remained outstanding as of September 30, 2024.

D ebt Overview Our debt obligations consisted of the following: September 30, December 31, 2024 2023 (In millions) 2018 Term Debt, interest rate of 8.0 % as of December 31, 2023 $ — $ 644.3 2024 Term Debt, interest rate of 7.3 % as of September 30, 2024 648.4 — 2018 Revolving Credit Facility ($ 300.0 million available capacity less $ 1.3 million as of December 31, 2023, reserved for letters of credit) — — 2024 Revolving Credit Facility ($ 350.0 million available capacity less $ 0.2 million as of September 30, 2024, reserved for letters of credit) — — Convertible Senior Notes, interest rate of 0.25 % 575.0 575.0 Line of Credit ($ 1.1 million and $ 0.5 million letter of credit capacity, respectively, which were fully utilized) — — Financing lease liabilities (Note 7) 6.7 7.3 Total debt 1,230.1 1,226.6 Less unamortized debt issuance costs and discount 12.9 8.9 Less current portion of long-term debt 7.3 7.6 Long-term debt, less current portion $ 1,209.9 $ 1,210.1 Accrued interest and fees related to the debt obligati ons was $ 0.7 million and $ 0.9 million as of September 30, 2024 and December 31, 2023, respectively, and is included within other accrued expenses in our condensed consolidated balance sheets. 2018 Senior Secured Credit Facility On April 30, 2018, we entered into a 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 “2018 Term Debt”) and (ii) a $ 300.0 million revolving credit facility (the “2018 Revolving Credit Facility”, and collectively with the 2018 Term Debt, the “2018 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 2018 Term Debt and 2018 Revolving Credit Facility were set to mature on April 30, 2025 and January 29, 2025 , respectively. We were 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. The 2018 Revolving Credit Facility did not require amortization payments. We repaid in full the 2018 Senior Secured Credit Facility in connection with our debt refinancing completed in February 2024. 2024 Senior Secured Credit Facility On February 29, 2024, we completed the refinancing of our 2018 Senior Secured Credit Facility by entering into a new credit agreement. Pursuant to the terms of the new credit agreement, we became the borrower of (i) a $ 650.0 million senior secured term loan facility (the “2024 Term Debt”) and (ii) a $ 350.0 million senior secured revolving credit facility (the “2024 Revolving Credit Facility”, and collectively, with the 2024 Term Debt, the “2024 Senior Secured Credit Facility”). The 2024 Term Debt and the 2024 Revolving Credit Facility will mature on March 1, 2031 and March 1, 2029 , respectively. The 2024 Senior Secured Credit Facility replaced the 2018 Senior Secured Credit Facility, and we repaid in full all outstanding obligations under the 2018 Senior Secured Credit Facility on February 29, 2024. Our obligations under the 2024 Senior Secured Credit Facility are secured by a lien on substantially all of our assets, as well as guarantees and pledged assets by our domestic subsidiaries, subject to certain exceptions. The 2024 Term Debt is subject to amortization of principal, payable in equal quarterly installments on the last day of each fiscal quarter, commencing on September 30, 2024 , with 0.25 % of the aggregate principal amount of all initial term loans outstanding at closing to be payable each quarter prior to the maturity date of the 2024 Term Debt. The remaining initial aggregate principal amount will be payable at the maturity date of the 2024 Term Debt. The 2024 Term Debt bears interest at rates based upon, at our option, either (i) a base rate plus an applicable percentage of 1.5 % or (ii) a term Secured Overnight Financing Rate ("SOFR") plus an applicable percentage of 2.5 %. The 2024 Revolving Credit Facility bears interest at rates based upon, at our option, either (i) the base rate or the Canadian prime rate, as applicable, plus an applicable percentage of between 1.25 % and 1.75 % per annum, depending on our consolidated first lien leverage ratio or (ii) the term SOFR rate or the Canadian Overnight Repo Rate Average ("CORRA") rate plus an applicable percentage of between 2.25 % and 2.75 % per annum, depending on our consolidated first lien leverage ratio. In connection with the refinancing of our debt, we capitalized $ 7.5 million of additional financing costs and recognized a loss on debt extinguishment of $ 4.3 million within interest expense, net in our condensed consolidated statements of operations for the nine months ended September 30, 2024. The 2024 Senior Secured Credit Facility documents contain a requirement that we maintain a ratio of first lien net leverage to Credit Facility EBITDA below specified levels on a quarterly basis; however, such requirement is applicable only if more than 35% of the 2024 Revolving Credit Facility is utilized. As of September 30, 2024, no portion of the 2024 Revolving Credit Facility was utilized. 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, 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 Part II, Item 8, Note 9, “Debt,” to our audited consolidated financial statements in our 2023 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 September 30, 2024. 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. The Convertible Senior Notes are accounted for as a single liability, and the carrying amount of the Convertible Senior Notes was $ 570.4 million as of September 30, 2024, with principal of $ 575.0 million , net of issuance costs of $ 4.6 million . The Convertible Senior Notes are included within long-term debt, less current portion in our condensed consolidated balance sheets as of September 30, 2024 . 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 September 30, Nine Months Ended September 30, 2024 2023 2024 2023 (Dollars in millions) Contractual interest expense $ 0.4 $ 0.4 $ 1.1 $ 1.1 Amortization of debt issuance costs 0.7 0.7 2.2 2.1 Total $ 1.1 $ 1.1 $ 3.3 $ 3.2 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 sheets, 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) 2024 $ 1.6 2025 6.5 2026 581.5 2027 6.5 2028 6.5 Thereafter 620.8 $ 1,223.4 Fair Value of Debt Our debt does not trade in active markets and was considered to be a Level 2 measurement at September 30, 2024 . The fair value of the 2018 Term Debt and 2024 Term Debt were based on the borrowing rates currently available to us for bank loans with similar terms, maturities, and volumes as 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 $ 1.19 billion and $ 1.16 billion as of September 30, 2024, and December 31, 2023 , respectively.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	11. Share-Based Compensation Our share-based compensation consists of stock options, restricted stock units (“RSU”), and performance stock units (“PSU”) and is used to compensate certain employees and non-employee directors. We also offer an employee stock purchase plan to eligible employees. Most of our equity awards vest either annually on a pro rata basis, generally over a one - or three-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 stock options have a 10-year contractual term and have an exercise price that is not less than the fair market value of the underlying common stock on the date of grant. As of September 30, 2024 , there were 12.6 million stock options, RSUs, and PSUs outstanding and 9.6 million shares available for grant under approved equity compensation plans. Total share-based compensation expense was $ 39.6 million and $ 36.3 million for the three months ended September 30, 2024, and 2023, respectively, and $ 118.4 million and $ 118.0 million for the nine months ended September 30, 2024, and 2023, respectively.

These awards are primarily earned upon performance of key financial metrics and certain LTI awards are earned based upon our total shareholder return, a market condition, as compared to an indexed shareholder return over the course of a fiscal based three-year performance period, starting in the year of grant. The probability of vesting will continue to be evaluated throughout 2024, and share-based compensation will be recognized in accordance with that probability. Earned awards typically vest in the quarter following the conclusion of the performance period. As of September 30, 2024 , there was $ 36.0 million of share-based compensation expense related to unvested PSUs not yet recognized, which is expected to be recognized over a weighted average period of 1.6 years.

Contract Balances In accordance with ASC 606, a contract asset is generally recorded when revenue recognized for professional service performance obligations exceed the contractual amount of billings for implementation related professional services. Additions to contract assets generally represent increases to professional services revenues, and reductions to contract assets generally represent reductions to recurring revenues during the initial contract term. Contract assets expected to be recognized in revenue within twelve months are included within prepaid expenses and other current assets, with the remaining contract assets included within other assets on our condensed consolidated balance sheets. The changes in total contract assets were as follows: Nine Months Ended September 30, 2024 2023 (In millions) Contract assets, beginning of period $ 89.0 $ 68.5 Additions 73.4 71.4 Reductions ( 63.8 ) ( 58.2 ) Foreign currency translation 0.3 ( 0.2 ) Contract assets, end of period $ 98.9 $ 81.5 Deferred Revenue Deferred revenue primarily consists of payments received in advance of revenue recognition.

Sales commissions paid based on the annual contract value are deferred and then amortized on a straight-line basis over a period of benefit that we have determined to be ten years. Amortization expense for deferred sales commissions was $ 7.2 million and $ 5.3 million for the three months ended September 30, 2024, and 2023, respectively, and $ 20.1 million and $ 15.0 million for the nine months ended September 30, 2024, and 2023, respectively. Transaction Price for Remaining Performance Obligations As of September 30, 2024 , approximately $ 1,310.4 million of revenue is expected to be recognized over the next three years from remaining performance obligations, which represents contracted revenue for recurring services and fixed price professional services, primarily implementation services, that has not yet been recognized, including deferred revenue and unbilled amounts that will be recognized as revenue in future periods. Performance obligations that are billed and recognized as they are delivered, primarily professional services contracts that are on a time and materials basis, are excluded from the transaction price for remaining performance obligations disclosed above .

Income Tax Disclosure [Abstract]
Income Taxes	14. 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 September 30, 2024 , we have a valuation allowance of $ 45.9 million against certain deferred tax assets consisting primarily of $ 31.8 million attributable to other deferred tax assets consisting largely of foreign intangible assets and $ 14.1 million attributable to state and foreign net operating loss carryovers. We recorded income tax expense of $ 16.3 million during the three months ended September 30, 2024 , which included tax expense of $ 7.4 million attributable to Global Intangible Low Taxed Income, $ 6.7 million attributable to share-based compensation, $ 3.8 million attributable to foreign tax rate differences, $ 3.8 million attributable to current operations, and $ 3.1 million of valuation allowance recorded, partially offset by $ 9.6 million of valuation allowance released and $ 1.9 million of tax credits. We recorded income tax expense of $ 29.4 million during the nine months ended September 30, 2024 , which included tax expense of $ 13.0 million attributable to Global Intangible Low Taxed Income, $ 11.4 million attributable to share-based compensation, $ 7.7 million attributable to current operations, $ 6.3 million attributable to foreign tax rate differences, and $ 3.1 million of valuation allowance recorded, partially offset by $ 12.0 million of valuation allowance released and $ 6.9 million of tax credits. The total amount of unrecognized tax benefits as of September 30, 2024, and December 31, 2023 , was $ 1.6 million and $ 1.0 million, respectively. The $ 1.6 million represents the amount that, if recognized, would impact our effective income tax rate as of September 30, 2024. We adjust 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 2019.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15. 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 Income (Loss) per Share	16. Net Income (Loss) per Share We compute net income (loss) per share of common stock using the treasury stock method. The basic and diluted net income (loss) per share computations were calculated as follows: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 (In millions, except per share data) Numerator: Net income (loss) $ 2.0 $ ( 3.8 ) $ 7.3 $ 9.2 Denominator: Weighted average shares outstanding - basic 158.1 155.7 157.6 155.0 Effect of dilutive equity instruments 1.6 — 2.3 3.2 Weighted average shares outstanding - diluted 159.7 155.7 159.9 158.2 Net income (loss) per share - basic $ 0.01 $ ( 0.02 ) $ 0.05 $ 0.06 Net income (loss) per share - diluted $ 0.01 $ ( 0.02 ) $ 0.05 $ 0.06 The following potentially dilutive weighted average shares were excluded from the calculation of diluted net income (loss) per share because their effect would have been anti-dilutive: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 (In millions) Stock options 2.9 3.1 3.0 2.4 Restricted stock units 2.7 0.6 1.5 0.1 Performance stock units 0.9 0.6 0.8 — The shares underlying the conversion option in the Convertible Senior Notes were not considered in the calculation of diluted net income (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 September 30, 2024 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 nine months ended September 30, 2024 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.
