Summary of Significant Accounting Policies | 2. Summary of Signif icant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). The accompanying consolidated financial statements include the operations and accounts of Ceridian and all subsidiaries, as well as any variable interest entity (“VIE”) in which we have controlling financial interest. All intercompany balances and transactions have been eliminated from our consolidated financial statements. We consolidate the grantor trusts that hold funds provided by our payroll and tax filing customers pending remittance to employees of those customers or tax authorities in the U.S. and Canada, although Ceridian does not own the grantor trusts. Under consolidation accounting, the enterprise with a controlling financial interest consolidates a VIE. A controlling financial interest in an entity is determined through analysis that identifies the primary beneficiary which has (1) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. In addition, ongoing reassessments must be performed to confirm whether an enterprise is the primary beneficiary of a VIE. The grantor trusts are VIEs, and we are deemed to have a controlling financial interest as the primary beneficiary. Please refer to Part II, Item 8, Note 4, “Customer Funds,” for further information on our accounting for these funds. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. Refer to the following section for additional information. In addition, we now present selling and marketing expenses and general and administrative expenses as separate line items on our consolidated statements of operations. Immaterial Correction of Prior Period Error During the year ended December 31, 2023, an error was discovered in the presentation of one Canadian bank account balance within “customer funds” and “customer funds obligations” and related items on our consolidated balance sheet as of December 31, 2022 and in our net cash provided by financing activities within our consolidated statements of cash flows for the years ended December 31, 2022 and 2021. There was an understatement of customer funds within current assets and a corresponding understatement of customer funds obligations within current liabilities on our consolidated balance sheet. As a result, we also erroneously presented certain changes related to customer funds and customer funds obligations on our consolidated statements of cash flows. The line items affected include “customer funds” and “customer funds obligations” on our consolidated balance sheets. The line items affected also include “increase (decrease) in customer funds obligations, net,” effect of exchange rate changes on cash, restricted cash, and equivalents,” “cash, restricted cash, and equivalents,” and “restricted cash and equivalents included in customer funds,” and “effect of exchange rate changes on cash, restricted cash, and equivalents” on our consolidated statements of cash flows. The amounts impacted by the correction are summarized as follows: Consolidated Balance Sheets (Selected financial statement line items only) December 31, 2022 As reported As restated Change (In millions) Customer funds $ 4,183.2 $ 4,729.5 $ 546.3 Customer funds obligations 4,298.8 4,845.1 546.3 Consolidated Statements of Cash Flows (Selected financial statement line items only) Year Ended December 31, 2022 2021 As reported As restated Change As reported As restated Change (In millions) Increase (decrease) in customer funds obligations, net $ 840.1 $ 734.6 $ ( 105.5 ) $ ( 195.7 ) $ ( 111.3 ) $ 84.4 Effect of exchange rate changes on cash, restricted cash, and equivalents ( 8.1 ) ( 46.8 ) ( 38.7 ) ( 20.9 ) ( 21.3 ) ( 0.4 ) Cash, restricted cash, and equivalents at beginning of period 1,952.8 2,643.3 690.5 2,228.5 2,835.0 606.5 Cash, restricted cash, and equivalents at end of period 2,604.9 3,151.2 546.3 1,952.8 2,643.3 690.5 Restricted cash and equivalents included in customer funds 2,172.2 2,718.5 546.3 1,583.4 2,273.9 690.5 In addition, our condensed consolidated statements of cash flows for certain historical quarterly periods will be restated in future Quarterly Reports on Form 10-Q. The following changes will be reflected in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024 and June 30, 2024: Condensed Consolidated Statements of Cash Flows (Selected financial statement line items only, unaudited) Three Months Ended March 31, 2023 Six Months Ended June 30, 2023 As reported As restated Change As reported As restated Change (In millions) Increase in customer funds obligations, net $ 2,078.1 $ 2,174.4 $ 96.3 $ 45.0 $ 100.4 $ 55.4 Effect of exchange rate changes on cash, restricted cash, and equivalents ( 7.7 ) ( 6.8 ) 0.9 ( 1.0 ) 63.1 64.1 Cash, restricted cash, and equivalents at beginning of period 2,604.9 3,151.2 546.3 2,604.9 3,151.2 546.3 Cash, restricted cash, and equivalents at end of period 4,697.9 5,341.4 643.5 2,775.9 3,441.7 665.8 Restricted cash and equivalents included in customer funds 4,268.5 4,912.0 643.5 2,288.5 2,954.3 665.8 Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of our financial statements and our reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates that could significantly affect our results of operations or financial condition include the assignment of fair values to goodwill and other intangible assets and testing for impairment; the testing of impairment of long-lived assets; the determination of our liability for pensions and postretirement benefits; the determination of fair value of equity awards granted; and the resolution of tax matters and legal contingencies. Further discussion on these estimates can be found in related disclosures elsewhere in our notes to the consolidated financial statements. Cash and Equivalents As of December 31, 2023 and 2022 , cash and equivalents were comprised of cash held in bank accounts and investments with an original maturity of three months or less. Concentrations Cash deposits of client and corporate funds are maintained primarily in large credit-worthy financial institutions in the countries in which we operate. These deposits may exceed the amount of any deposit insurance that may be available through government agencies. All deliverable securities are held in custody with large credit-worthy financial institutions, which bear the risk of custodial loss. Non-deliverable securities, primarily money market securities, are held in custody by large, credit-worthy broker-dealers and financial institutions. Trade and Other Receivables, Net Trade and other receivables balances are presented on the consolidated balance sheets net of the allowance for doubtful accounts and the reserve for sales adjustments. We experience credit losses on accounts receivable and, accordingly, must make estimates related to the ultimate collection of the receivables. Specifically, management analyzes accounts receivable, historical bad debt experience, customer concentrations, customer creditworthiness, and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. We estimate the reserve for sales adjustment based on historical sales adjustment experience. We write off accounts receivable when we determine that the accounts are uncollectible, generally upon customer bankruptcy or the customer’s nonresponse to continued collection efforts. Property, Plant, and Equipment, Net Our property, plant, and equipment assets are stated at cost less accumulated depreciation. Depreciation is calculated on a straight-line basis over the shorter of the remaining lease term or estimated useful life of the related assets, which are generally as follows: Building improvements 5 years Machinery and equipment 4 - 6 years Computer equipment 3 - 4 years Repairs and maintenance costs are expensed as incurred. We capitalized interest of $ 0.7 million and $ 0.8 million in property, plant, and equipment, net during the years ended December 31, 2023 and 2022, respectively. Property, plant, and equipment assets are assessed for impairment as described under the heading “Impairment of Long-Lived Assets” below. Business Combinations In accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, we use the acquisition method of accounting and allocate the fair value of purchase consideration to the assets acquired and liabilities assumed based on their respective estimated fair values as of the acquisition date. Goodwill represents the excess of purchase consideration transferred over the estimated fair value of the identifiable net assets acquired in a business combination. Assigning estimated fair values to the net assets acquired requires the use of significant estimates, judgments, inputs, and assumptions regarding the fair value of the assets acquired and liabilities assumed. Estimated fair values of assets acquired and liabilities assumed are generally based on available historical information, independent valuations or appraisals, future expectations, and assumptions determined to be reasonable but are inherently uncertain with respect to future events, including economic conditions, competition, the useful life of the acquired assets, and other factors. The measurement period for assigning fair values to the net assets acquired will end when the information, or the facts and circumstances, becomes available, but will not exceed one year from the date of acquisition. The judgments made in determining the estimated fair value assigned to assets acquired and liabilities assumed, as well as the estimated useful life and depreciation or amortization method of each asset, can materially impact the net earnings of the periods subsequent to the acquisition through depreciation and amortization, and in certain instances through impairment charges, if the asset becomes impaired in the future. During the measurement period, any purchase price allocation changes that impact the carrying value of goodwill affects any measurement of goodwill impairment taken during the measurement period, if applicable. If necessary, purchase price allocation revisions that occur outside of the measurement period are recorded within our consolidated statement of operations depending on the nature of the adjustment. Segment Information We operate as a single reporting unit, a single operating segment and a single reporting segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assessing performance. Our chief operating decision maker is our chief executive officer ("CEO"). Goodwill and Intangible Assets Goodwill represents the excess of purchase consideration transferred over the estimated fair value of the identifiable net assets acquired in a business combination. Goodwill and our indefinite-lived intangible asset, the Dayforce trade name, are not amortized against earnings, but instead are tested for impairment on an annual basis, or more frequently if certain events or circumstances occur that could indicate impairment. We perform our annual impairment assessment of goodwill and the Dayforce trade name as of October 1. We assess goodwill for impairment by performing a qualitative review of the reporting unit. If the qualitative assessment indicates it is more likely than not the fair value of the reporting unit is less than the carrying amount, a quantitative test is applied and, the carrying amount is compared to its estimated fair value. The estimated fair value is based on our market capitalization at the testing date. If the carrying amount of the goodwill exceeds the fair value of the reporting unit, goodwill may be impaired. To the extent that the carrying amount of the reporting unit exceeds the fair value of the reporting unit, an impairment loss is recognized. We assess our indefinite-lived intangible asset for impairment by performing a qualitative review. If the qualitative assessment indicates it is more likely than not the fair value of the asset is less than the carrying amount, a quantitative test is applied and, the carrying amount is compared to its estimated fair value. The estimate of fair value is based on a relief from royalty method which calculates the cost savings associated with owning rather than licensing the trade name. An estimated royalty rate is applied to forecasted revenue and the resulting cash flows are discounted. Definite-lived assets are assessed for impairment as described under the heading “Impairment of Long-Lived Assets” below. Intangible assets represent amounts assigned to specifically identifiable intangible assets at the time of an acquisition. Definite-lived assets are amortized on a straight-line basis generally over the following periods: Customer lists and relationships 4 - 12 years Trade name 2 - 5 years Technology 3 - 5 years Internally Devel oped Software Costs In accordance with ASC Topic 350, we capitalize costs associated with software developed or obtained for internal use when both the preliminary project stage is completed and our management has authorized further funding for the project, which it deems probable of completion. Capitalized software costs include only: (1) external direct costs of materials and services consumed in developing or obtaining the software; (2) payroll and payroll-related costs for employees who are directly associated with and who devote time to the project; and (3) interest costs incurred while developing the software. Capitalization of these costs ceases no later than the point at which the project is substantially complete and ready for its intended purpose. We do not include general and administrative costs and overhead costs in capitalizable costs. Research and development costs, product management, and other software maintenance costs related to software development are expensed as incurred. We had capitalized software costs, net of accumulated amortization, of $ 167.0 million and $ 133.4 million as of December 31, 2023, and 2022 , respectively, included in property, plant, and equipment, net in the consolidated balance sheets. We amortize software costs on a straight-line basis over the expected life of the software, generally a range of two to seven years . Amortization of software costs totaled $ 54.0 million, $ 43.5 million, and $ 37.0 million for the years ended December 31, 2023, 2022, and 2021 , respectively. Impairm ent of Long-Lived Assets Long-lived assets, such as property, plant, and equipment, capitalized software, and definite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Recoverability of asset groups to be held and used is measured by a comparison of the carrying amount of an asset group to the estimated undiscounted future cash flows expected to be generated by the asset group. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. Deferred Costs Deferred costs primarily consist of deferred sales commissions. Sales commissions paid based on the annual contract value of a signed customer contract are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions pai d based on the annual contract value are deferred and then amortized on a straight-line basis over a period of benefit. As of December 1, 2022, we increased the expected period of benefit of our deferred sales commissions from five years to ten years . This change in accounting estimate and related customer period of benefit is largely attributable to new evidence of longer customer relationships such as increases in the proportion of new customer contracts greater than three years as well as our continued high customer retention rates. The change was made on a prospective basis. Deferred costs included within Other assets on our consolidated balance sheets were $ 192.1 million and $ 151.2 million as of December 31, 2023 and 2022 , respectively. Amortization expense for the deferred costs was $ 21.0 million, $ 48.9 million, and $ 46.4 million for the years ended December 31, 2023, 2022, and 2021 respectively. Revenue Recognition The core principle of ASC Topic 606 is that revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. In accordance with ASC Topic 606, we perform the following steps to determine revenue to be recognized: 1) Identify the contract(s) with a customer; 2) Identify the performance obligations in the contract; 3) Determine the transaction price; 4) Allocate the transaction price to the performance obligations in the contract; and 5) Recognize revenue when (or as) we satisfy a performance obligation. The significant majority of our two major revenue sources (recurring and professional services and other) are derived from contracts with customers. Recurring revenues are primarily related to our Cloud subscription performance obligations. Professional services and other revenues are primarily related to professional services for our Cloud customers (including implementation services to activate new accounts, as well as post go-live professional services typically billed on a time and materials basis) and, to a much lesser extent, fees for other non-recurring services, including sales of time clocks and certain client reimbursable out-of-pocket expenses. Fees charged to Cloud subscription performance obligations are generally priced either on a per-employee, per-month (“PEPM”) basis for a given month or on a per-employee, per-process basis for a given process; and fees charged for professional services are typically priced on a fixed fee basis for activating new accounts and on a time and materials basis for post go-live professional services. There is typically no variable consideration related to our recurring Cloud subscriptions or our activation services, nor do they include a significant financing component, non-cash consideration, or consideration payable to a customer. Our recurring Cloud subscriptions are typically billed one month in advance while our professional services are billed over the implementation period for activation of new accounts and as work is performed for post go-live professional services. Our Cloud services arrangements include multiple performance obligations, and transaction price allocations are based on the stand-alone selling price ("SSP") for each performance obligation. Our contract renewal rates serve as an observable input to establish SSP for our recurring Cloud subscription performance obligations. The SSP for professional services performance obligations is estimated based on market conditions and observable inputs, including hours incurred and rates charged by third parties to perform implementation services. For our performance obligations, the consideration allocated to Cloud subscription revenues is recognized as recurring revenues, typically commencing when an instance is provisioned to the customer. The consideration allocated to professional services to activate a new account is recognized as professional services revenues based on the proportion of total work performed, using reasonably dependable estimates (in relation to progression through the implementation phase), by solution. Recurring Revenues For our Dayforce solutions, we primarily charge monthly recurring fees on a PEPM basis, generally one-month in advance of service, based on the number and type of solutions provided to the customer and the number of employees at the customer. We charge Powerpay customers monthly recurring fees on a per-employee, per-process basis. For our other recurring solutions, we typically charge monthly recurring fees on a per-process basis. The typical recurring customer contract has an initial term between three and five years . Any credits related to service level commitments are recognized as incurred, as service level failures are not anticipated at contract signing. Should a customer cancel the initial contract, an early termination fee may be applicable, and revenue is recognized upon col lection. We also generate recurring revenue from investment income on our Cloud recurring and other recurring customer funds before such funds are remitted to taxing authorities, customer employees, or other third parties. We refer to this investment income as float revenue. Please refer to Part II, Item 8, Note 12, “Revenue,” for a full description of our sources of revenue. Professional Services and Other Revenues Professional services and other revenues consist primarily of charges relating to the work performed to assist customers with the planning, design, and implementation of their solutions. Also included in professional services are any related training services, post-implementation professional services, and shipment of time clocks purchased by customers. We also generate professional services and other revenues from custom professional services and consulting services that we provide and for certain third-party services that we arrange for our Other recurring customers. Professional services revenue is primarily recognized as hours are incurr ed. Costs and Expenses Cost of Revenue Cost of revenue consists of costs to deliver our revenue-producing services. Most of these costs are recognized as incurred, that is, as we become obligated to pay for them. Some costs of revenue are recognized in the period that a service is sold and delivered. Other costs of revenue are recognized over the period of use or in proportion to the related revenue. The costs recognized as incurred consist primarily of customer service staff costs, customer technical support costs, implementation personnel costs, costs of hosting applications, consulting and purchased services, delivery services, and royalties. The costs of revenue recognized over the period of use are depreciation and amortization, rentals of facilities and equipment, and direct and incremental costs associated with deferred implementation service revenue. Cost of recurring revenues primarily consists of costs to provide maintenance and technical support to our customers, and the costs of hosting our applications. The cost of recurring revenues includes compensation and other employee-related expenses for data center staff, payments to outside service providers, data center, and networking expenses. Cost of professional services and other revenues primarily consists of costs to provide implementation consulting services and training to our customers, as well as the cost of time clocks. Costs to provide implementation consulting services include compensation and other employee-related expenses for professional services staff, costs of subcontractors, and travel. Product development and management expense includes costs related to software development activities that do not qualify for capitalization, such as development, quality assurance, testing of new technologies, and enhancements to our existing solutions that do not result in additional functionality. Product development and management expense also includes costs related to the management of our solutions. Research and development expense was $ 112.0 million , $ 92.3 million , and $ 81.1 million for the years ended December 31, 2023, 2022, and 2021, respectively. Depreciation and amortization related to cost of revenue primarily consists of amortization of capitalized software. Selling and Marketing Expense Selling and marketing expense includes costs related to maintaining a direct marketing infrastructure and sales force and other direct marketing efforts, such as marketing events, advertising, telemarketing, direct mail, and trade shows. Advertising costs are expensed as incurred. Advertising expense was $ 14.2 million, $ 11.3 million, and $ 7.5 million for the years ended December 31, 2023, 2022, and 2021 , respectively. General and Administrative Expense General and administrative expense includes costs that are not directly related to delivery of services, selling efforts, or product development, primarily consisting of corporate-level costs, such as administration, finance, legal, and human resources. Also included in this category are depreciation, and amortization of other intangible assets not reflected in cost of revenue, and the provision for doubtful accounts receivable. Other Expense (Income), Net Other expense (income), net includes the results of transactions that are not appropriately classified in another category. These items are primarily foreign currency translation gains and losses resulting from transactions denominated in foreign currencies and net periodic pension costs. Income Taxes Income taxes have been provided for using the asset and liability method. Deferred tax assets and liabilities are recorded for temporary differences between the financial reporting basis and the tax basis of assets and liabilities as adjusted for the expected benefits of utilizing net operating loss carryforwards. The impact on deferred taxes of changes in tax rates and laws, if any, applied to the years during which temporary differences are expected to be settled, is reflected in the consolidated financial statements in the period of enactment. We classify interest and penalties related to income taxes as a component of income tax expense (benefit). Fair Value of Financial Instruments The carrying amounts of cash and equivalents, trade and other receivables, net, customer funds obligations, customer advance payments, and accounts payable approximate fair value because of the short-term nature of these items. Share-Based Compensation Our share-based compensation consists of stock options, restricted stock units (“RSU”), and performance-based stock units (“PSU”) and is used to compensate employees and non-employee directors. We also offer a global employee stock purchase plan ("GESPP") to eligible employees. We measure share-based compensation cost at the grant date based on the fair value of the award and recognize the compensation expense over the requisite service period, which is the period during which an employee is required to provide services in exchange for the award, except for retirement-eligible employees with RSUs that have not given their required notice, which accelerates at the time of their retirement eligibility date. We estimate forfeitures at the time of grant based on historical data and record share-based compensation expense for those awards expected to vest. Our GESPP allows participating employees to purchase shares of our common stock at a discount via payroll deductions. The plan is available to employees subject to certain eligibility requirements. Participating employees may purchase common stock, on a voluntary after-tax basis, at a price that is the lower of 85 % of the fair market value of a share of common stock on (i) January 1 or (ii) the purchase date. The plan consists of four three-month offering periods, beginning on January 1, April 1, July 1, and October 1 of each calendar year. The fair value of term-based stock options and our GESPP activity is estimated using the Black-Scholes standard option pricing model (“Black-Scholes model”). The fair value for RSUs and PSUs is the closing market value of the underlying stock on the day of grant. For performance-based stock options and PSUs with a market condition, a Monte Carlo simulation model is used to determine the fair value. The Monte Carlo model utilizes multiple input variables that determine the probability of satisfying the market conditions stipulated in the award. To determine the fair value of the awards on the date of grant using the Black-Scholes model, the risk-free interest rate used was based on the implied yield currently available on U.S. Treasury zero coupon issues with remaining term equal to the contractual term of the performance-based options and the expected term of the term-based awards. The estimated volatility of our common stock is based on volatility data for selected comparable public companies, including the historical volatility of our stock price, over the expected term of our stock awards. Because we do not anticipate paying any cash dividends in the foreseeable future, we use an expected dividend yield of zero. The amount of share-based compensation expense we recognize during a period is based on the portion of the awards that are ultimately expected to vest. For most awards, we recognize stock compensation expense using the straight-line method. For awards based on a market condition, expense is recognized on a straight-line basis over the performance period, regardless of whether the market condition is satisfied as the likelihood of the market condition being met is included in the fair-value measurement of the award. If factors change and we employ different assumptions for estimating share-based compensation expense in future periods or if we adopt a different valuation model, future periods may differ significantly from what we have recorded in the current period and could materially affect our operating results. Pension and Other Postretirement Benefits Liability We present information about our pension and postretirement benefit plans in Part II, Item 8, Note 10, “Employee Benefit Plans” to our consolidated financial statements. Liabilities and expenses for pensions and other postretirement benefits are determined with the assistance of third-party actuaries, using actuarial methodologies and incorporating significant assumptions, including the rate used to discount the future estimated liability, the long-term rate of return on plan assets, and several assumptions relating to the employee workforce (medical costs, retirement age, and mortality). The discount rate assumption utilizes a full yield curve approach by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. The impact of a change in the discount rate of 25 basis points would be approximately $ 6.6 million on the liabilities and an immaterial impact on pre-tax earnings in the following year. The long-term rate of return is estimated by considering historical returns and expected returns on current and projected asset allocations and is generally applied to a five-year average market value of assets. A change in the assumption for the long-term rate of return on plan assets of 25 basis points would impact pre-tax earnings by approximately $ 0.9 million. Foreign Currency Translation We have international operations whereby the local currencies serve as functional currencies. We translate foreign currency denominated assets and liabilities at the end-of-period exchange rates and foreign currency denominated statements of operations at the average exchange rates for each period. We report the effect of changes in the U.S. dollar carrying values of assets and liabilities of our international subsidiaries that are due to changes in exchange rates between the U.S. dollar and the subsidiaries’ functional currency as foreign currency translation within accumulated other comprehensive income (loss) in the accompanying consolidated statements of stockholders’ equity and comprehensive income (loss). Gains and losses from transactions and translation of assets and liabilities denominated in currencies other than the functional currency of the subsidiaries are recorded in the consolidated statements of operations within other expense (income), net.
