Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies Use of Estimates The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, collectability of accounts receivable, valuation of non-marketable securities, costs to complete certain contracts, valuation of acquired assets and liabilities, valuation of stock options, income tax accruals and the value of deferred tax assets and liabilities. Estimates are also used to determine the remaining economic lives and carrying value of fixed assets, goodwill and intangible assets. Actual results could differ from those estimates. Principles of Consolidation The Consolidated Financial Statements include the accounts of us and our subsidiaries. All significant accounts, transactions and profits between the consolidated companies have been eliminated in consolidation. We consolidate any entity in which we have a controlling financial interest. Under the voting interest model, generally the investor that has voting control (usually more than 50 % of an entity’s voting interests) consolidates the entity. Under the variable interest entity (“VIE”) model, the party that has the power to direct the entity’s most significant economic activities and the ability to participate in the entity’s economics consolidates the entity. An entity is considered a VIE if it possesses any one or more of the following characteristics: 1) the entity is thinly capitalized; 2) residual equity holders do not control the entity; 3) equity holders are shielded from economic losses; 4) equity holders do not participate fully in an entity’s residual economics; and 5) the entity was established with non-substantive voting interests. We have consolidated one VIE since we are the primary beneficiary as discussed in Note 12 below. Our investments in private equity funds meet the definition of a VIE; however, the private equity fund investments are not consolidated as we do not have the power to direct the entities’ most significant economic activities. We are the lessee in a series of operating leases covering a large portion of our Kansas City, Missouri-based leased office facilities. The lessors are generally joint ventures (in which we have 50 % ownership) that have been established specifically to purchase, finance and engage in leasing activities with the joint venture partners and unrelated third parties. Our analysis of our real estate joint ventures for all periods presented indicate that none qualified as a VIE and, accordingly, they have not been consolidated. Unconsolidated investments in entities over which we do not have control but have the ability to exercise influence over operating and financial policies, if any, are accounted for under the equity method of accounting. Earnings and losses from such investments are recorded on a pre-tax basis, if any. Revenue Recognition We account for the recognition of our revenue in accordance with the relevant accounting literature, primarily Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (ASC 606). Our sources of revenue are described below. Software-enabled Services Revenue We primarily offer software-enabled outsourcing services in which we utilize our own software to offer comprehensive fund administration services for alternative investment managers, including fund manager services, transfer agency services, funds-of-funds services, tax processing and accounting. We also use our own software applications to provide healthcare organizations a variety of medical and pharmacy benefit solutions to satisfy their information processing, quality of care, cost management concerns and payment integrity programs. Our healthcare solutions include claims adjudication, benefit management, care management, business intelligence and other ancillary services. We also offer subscription-based on-demand software applications that are managed and hosted at our facilities. The software-enabled services arrangements provide an alternative for clients who do not wish to install, run and maintain complicated financial software. Under these arrangements, the client does not have the right to take possession of the software, rather, we agree to provide access to our applications, remote use of our equipment to process transactions, access to client’s data stored on our equipment and connectivity between our environment and the client’s computing systems. Software-enabled services are generally provided under contracts with initial terms of one to five years that require monthly or quarterly payments, and are subject to automatic annual renewal at the end of the initial term unless terminated by either party. In software-enabled services arrangements, the arrangement is a single performance obligation or a stand-ready performance obligation, which in either case is comprised of a series of distinct services that are substantially the same and have the same pattern of transfer to the customer (i.e. distinct days or months of service). We apply a measure of progress (typically time-based) to any fixed consideration and allocate variable consideration to the distinct periods of service based on usage or summarization of account information. These variable payments relate specifically to our efforts to perform the services in the period in which the fee applies. This variability is solely attributed to and resolved as a result of the transfer of these services; these fees are independent of the transfer of past or future goods or services. These fees meet the allocation objective of Accounting Standards Codification (“ASC”) 606 because they represent the amount of consideration we are entitled to for these services. Revenue is generally recognized over the period the services are provided, which results in revenue recognition that corresponds with the value to the client of the services transferred to date relative to the remaining services promised. For our software-enabled services contracts, which are cancelable with 90 days’ notice or meet the allocation objective for a series of performance obligations under ASC 606, we have not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or when we expect to recognize this revenue. License, Maintenance and Related Revenue Agreements We generate revenues in the form of software license fees and related maintenance and services fees. License fees include perpetual license fees and term license fees that differ mainly in the duration over which the customer benefits from the software. Maintenance and services primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available) and, in some cases, professional services which focus on both deployment and training our customers to fully leverage the use of our products. Under ASC 606, we identify a contract with a customer, we identify the performance obligations in the contract, we determine the transaction price, we allocate the transaction price to each performance obligation in the contract and recognize revenues when (or as) we satisfy a performance obligation. Software license performance obligations are functional intellectual property that are distinct as the user can benefit from the software on its own as defined under ASC 606. Software license revenues are recognized at the point of time when the software license has been delivered. Term license fees are typically due in annual installments at the beginning of each annual period and we record a contract asset for amounts recognized as revenue in excess of amounts billed. We recognize maintenance revenues ratably over the term of the underlying contract term because we transfer control evenly by providing a stand-ready service. The term of the maintenance contract on a perpetual license is usually one year and the duration of a term license contract is usually between one to five years . Renewals of maintenance contracts create new performance obligations that are satisfied over the term with the revenues recognized ratably over the term. Revenues from professional services consist mostly of services provided on a time and materials basis. The performance obligations are satisfied, and revenues are recognized, over time as the services are provided. In contracts with multiple performance obligations, we account for individual performance obligations separately if they are distinct. We allocate the transaction price to each performance obligation based on our relative standalone selling price out of total consideration of the contract. Standalone selling price is determined utilizing observable prices to the extent available. If the standalone selling price for a performance obligation is not directly observable, we estimate it maximizing the use of observable inputs. For maintenance and support, we determine the standalone selling price based on the price at which we separately sell a renewal contract and the economic relationship between licenses and maintenance. We primarily determine the standalone selling price for sales of license arrangements using the residual approach. In situations when the software license and the right to unspecified product upgrades are not distinct in the context of the contract, they are combined into a single performance obligation and revenue is recognized on a straight line basis over the contract duration. For professional services, we determine the standalone selling prices based on the price at which we separately sell those services. We occasionally enter into license agreements requiring significant customization of our software that are not material to our results of operations. We account for the license and professional service fees under these agreements as a single performance obligation, recognized over time using an input method during the development of the license. This method requires estimates to be made for costs to complete the agreement utilizing an estimate of development man-hours remaining. Revenue is recognized each period based on the hours incurred to date compared to the total hours expected to complete the project. Due to uncertainties inherent in the estimation process, it is at least reasonably possible that completion costs will be revised. Such revisions are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are determined on a contract-by-contract basis, and are made in the period in which such losses are first estimated or determined. We do not account for significant financing components if the period between when we transfer the promised product or service to the client and when the client pays for that product or service will be one year or less. We record revenue net of any taxes assessed by governmental authorities. Accounts Receivable, net is primarily comprised of billed and unbilled receivables for which we have an unconditional right to consideration, net of an allowance for credit losses. Costs of Revenues Costs of revenues include all costs, including depreciation and amortization, incurred to produce revenues. Incremental costs of obtaining a contract (e.g., sales commissions) are capitalized and amortized on a basis consistent with the pattern of transfer of goods or services to the customer to which the asset relates over the expected customer relationship period if we expect to recover those costs. The expected customer relationship period is determined based on average historical customer relationship periods, including expected renewals. Expected renewal periods are only included in the expected customer relationship period if commission amounts paid upon renewal are not commensurate with amounts paid on the initial contract. Incremental costs of obtaining a contract include only those costs we incur to obtain a contract that we would not have incurred if the contract had not been obtained. We have determined that certain commissions programs meet the requirements to be capitalized. Certain sales commissions associated with multi-year contracts are subject to an employee service requirement. As an action other than each party approving the contract is required to trigger payment of these sales commissions, they are not considered incremental costs to obtain a contract and are expensed as incurred. These costs are included in selling and marketing. We expense sales commissions as incurred when the amortization period would have been one year or less. Research and Development Research and development costs associated with computer software are charged to expense as incurred. Capitalization of internally developed computer software costs in the case of software to be sold begins upon the establishment of technological feasibility based on a working model. Capitalization of internally developed computer software costs in the case of internal use software begins when management authorizes and commits funding to a project and the preliminary design stage has been completed. Our policy is to amortize these costs upon a product’s general release to the client. Amortization of capitalized software costs is calculated by the greater of (a) the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or (b) the straight-line method over the remaining estimated economic life of the product, including the period being reported on, typically two to five years . Stock-based Compensation Using the fair value recognition provisions of relevant accounting literature, stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the appropriate service period. Determining the fair value of stock-based awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of our stock price. In addition, for stock-based awards where vesting is dependent upon achieving certain operating performance goals, we estimate the likelihood of achieving the performance goals. Differences between actual results and these estimates could have a material effect on our financial results. Forfeitures are accounted for as they occur. A deferred income tax asset is recorded over the vesting period as stock compensation expense is recorded for non-qualified option awards. The realizability of the deferred tax asset is ultimately based on the actual value of the stock-based award upon exercise. If the actual value is lower than the fair value determined on the date of grant, then there would be an income tax expense for the portion of the deferred tax asset that is not realizable. Income Taxes We account for income taxes in accordance with the relevant accounting literature. An asset and liability approach is used to recognize deferred tax assets and liabilities for the future tax consequences of items that are recognized in our financial statements and tax returns in different years. A valuation allowance is established against net deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. We account for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50 % likely of being realized upon ultimate settlement. We consider many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. Cash and Cash Equivalents We consider all highly liquid marketable securities with original maturities of three months or less at the date of acquisition to be cash equivalents. Funds Receivable and Funds Held on Behalf of Clients We hold client funds on behalf of transfer agency clients and pharmacy processing clients in connection with providing our data processing services. End-of-day available client bank balances for full service mutual fund transfer agency clients are invested overnight in credit quality government money market funds, bank deposits and repurchase agreements. Invested balances are returned to the full service mutual fund transfer agency clients’ accounts the following business day. Funds received from clients for the payment of pharmacy claims incurred by its members are invested in credit quality government money market funds, bank deposits and repurchase agreements until the paid claims are settled. Client funding receivables represent amounts due to us for pharmacy claims paid in advance of receiving client funding and for pharmacy claims processed for which client funding requests have not been made. Funds held on behalf of clients in the form of cash, cash equivalents and certificates of deposit with a maturity of less than twelve months are included in funds receivable and funds held on behalf of clients in the Consolidated Balance Sheet. Funds held on behalf of clients in the form of certificates of deposit with a maturity of greater than twelve months are classified as investments on the Consolidated Balance Sheets. All funds held on behalf of clients represent assets that are restricted for use. We have included funds held on behalf of clients that meet the definition of restricted cash and restricted cash equivalents in the beginning and end of period balances in the Consolidated Statements of Cash Flows. Cash inflows and outflows related to investment of funds held on behalf of clients are reported on a gross basis as “Investments in securities” and “Proceeds from sales / maturities of investments” in the investing section of the Consolidated Statements of Cash Flows. Client Funds Obligations Client funds obligations represent funds owed to full service mutual fund transfer agency clients for cash balances invested overnight, and our contractual obligations to satisfy client pharmacy claim obligations that are recorded on the balance sheet when incurred, generally after we have processed a claim on behalf of its pharmacy clients. Restricted Cash Restricted cash primarily includes amounts held by a bank as security for letters of credit issued due to lease requirements for office space. The letters of credit are expected to be renewed within the next twelve months, and as such, the restricted cash is classified as a current asset on the Consolidated Balance Sheets. Investments and Unconsolidated Affiliates We hold various investments, including investments in marketable securities, non-marketable securities and partnership interests in private equity funds, joint ventures and other similar entities. The equity method of accounting is used for investments in entities, partnerships and similar interests (including investments in private equity funds where we are a limited partner and hold a greater than 5 % partnership interest in the fund) in which we have significant influence but do not control. Under the equity method, we recognize income or losses from our pro-rata share of these unconsolidated affiliates’ net income or loss, which changes the carrying value of the investment of the unconsolidated affiliate. We measure equity investments in marketable securities, seed capital investments and other investments, other than those accounted for under the equity method of accounting or those that result in consolidation of the investee, at fair value, with changes in the fair value recognized in earnings. We use net asset value as a practical expedient for the fair value of partnership interests in private equity funds that are not accounted for under the equity method of accounting. Investments in non-marketable equity securities that do not have readily determinable fair values and do not qualify for the practical expedient to measure the investment using a net asset value per share are recorded using the measurement alternative in ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities . These investments are recorded at cost, less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. At each reporting period, we assess if these investments continue to qualify for this measurement alternative. Impairment is recorded when there is evidence that the expected fair value of the investment has declined to below the recorded cost. We have certain investments in unconsolidated affiliates accounted for under the equity method of accounting in which our carrying value exceeds our proportionate share of net assets of the unconsolidated affiliate. The total investment in unconsolidated affiliates, including basis differences, is included in unconsolidated affiliates on the Consolidated Balance Sheet. We record our proportionate share of the results of the unconsolidated affiliates and amortization expense related to basis differences in equity in earnings of unconsolidated affiliates, net on the Consolidated Statements of Comprehensive Income. Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation of property, plant and equipment is calculated using a combination of straight-line and accelerated methods over the estimated useful lives of the assets as follows: Description Useful Life Land – Buildings 40 years Building improvements Shorter of 40 years or remaining life of the building Equipment and software 3 - 5 years Furniture and fixtures 7 - 10 years Leasehold improvements Shorter of lease term or estimated useful life Maintenance and repairs are expensed as incurred. The costs of sold or retired assets are removed from the related asset and accumulated depreciation accounts and any gain or loss is included in the Consolidated Statements of Comprehensive Income. Leases We account for our leases in accordance with ASC 842. We determine if our contractual agreements contain a lease at inception. A lease is identified when a contract allows us the right to control an identified asset for a period of time in exchange for consideration. Our lease agreements consist primarily of operating leases for office space. Our operating leases are included on the Consolidated Balance Sheets as operating lease assets and operating lease liabilities, under ASC 842. An operating lease asset represents our right to use an underlying asset over the term of a lease while an operating lease liability represents our obligation to make lease payments arising from the lease. Operating lease liabilities are recognized at the commencement date at the present value of the base minimum rent payments. Operating lease assets are also recognized at the commencement date as the total operating lease liability adjusted for prepaid rents, deferred rent liabilities and lease fair value adjustments that existed under ASC 840. As most of our leases do not provide an implicit rate, we use our estimated secured incremental borrowing rate within each of the significant geographic regions in which we operate based on the information available at lease commencement date in determining the present value of lease payments. Our lease agreements typically do not contain variable lease payments, residual value guarantees or restrictive covenants. Many of our leases include the option to renew, however we do not believe it is reasonably certain that we will exercise the options as each individual lease is evaluated and further negotiated prior to the end of the current lease terms. Generally, our lease agreements include required separate payments for non-lease components (e.g. payments for common area maintenance, real estate taxes and/or utilities) which are expensed as incurred. We do have certain lease agreements that contain bundled minimum payments for lease components (e.g. payments for rent) and non-lease components. In these situations, we have applied the practical expedient available under ASC 842 to not separate the lease and non-lease components for purposes of the right-of-use asset and lease payment obligation calculations. Goodwill and Intangible Assets We test goodwill annually for impairment as of December 31 st (and in interim periods if certain events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount). We have completed the required impairment tests for goodwill and have determined that no impairment existed as of December 31, 2022 or 2021 . As of December 31, 2022 and 2021 , we have two reporting units, one is our health business and the other includes the rest of our operations. Our impairment analysis indicated that the fair value significantly exceeded the carrying value of each of our reporting units as of December 31, 2022 and 2021 . We measure the fair value of our reporting units utilizing the income method. Significant judgment is required to determine appropriate revenue growth rates and estimate the fair value of our reporting units. There were no other indefinite-lived intangible assets as of December 31, 2022 or 2021. Customer relationships, completed technology, trade names and other identifiable intangible assets are amortized over lives ranging from two to 17 years . Completed technology and customer relationships are amortized each year based on the ratio that the projected cash flows for the intangible assets bear to the total of current and expected future cash flows for the intangible asset. Trade names are amortized on a straight line basis. Impairment of Long-Lived Assets We evaluate the recoverability of our long-lived assets when there is evidence that events or changes in circumstances have made recovery of the carrying value of the asset or asset group unlikely. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset or asset group. We have identified no such impairment losses in the years ended December 31, 2022 and 2021 . Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash, cash equivalents, marketable securities and trade receivables. We have cash investment policies that limit investments to investment grade securities. Concentrations of credit risk, with respect to trade receivables, are limited due to the fact that our client base is highly diversified. As of December 31, 2022 and 2021 , we had no significant concentrations of credit. International Operations and Foreign Currency The functional currency of each foreign subsidiary is generally the local currency. Accordingly, assets and liabilities of foreign subsidiaries are translated to U.S. dollars at period-end exchange rates, and capital stock accounts are translated at historical rates. Revenues and expenses are translated using the average rates during the period. The resulting translation adjustments are excluded from net earnings and accumulated as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included within other income (expense) in the Consolidated Statements of Comprehensive Income in the periods in which they occur. Comprehensive Income Our comprehensive income consists of net income, foreign currency translation adjustments, a defined benefit pension plan and our proportionate share of the change in value of an interest rate swap agreement that one of our unconsolidated affiliates is a party to, which are presented in the Consolidated Statements of Comprehensive Income, net of tax and reclassifications to earnings. The accumulated balance of other comprehensive income is reported separately from retained earnings and additional paid-in capital in the stockholders’ equity section of the Consolidated Balance Sheets. Total comprehensive income consists of net income and other accumulated comprehensive (loss) income disclosed in the equity section of the Consolidated Balance Sheets. Treasury Stock Treasury stock purchases are accounted for under the cost method and are included as a deduction from equity in the stockholders’ equity section of the Consolidated Balance Sheets. Under the cost method, the price paid for the stock is charged to the treasury stock account. We use the average cost method to reduce the value of the treasury stock account if treasury stock is re-issued. Contingencies Loss contingencies from legal proceedings and claims may occur from government investigations, shareholder lawsuits, contractual claims, tax and other matters. Accruals are recognized when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. Gain contingencies are not recognized until realized. Legal fees are expensed as incurred. Recently Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities From Contracts with Customer. ASU 2021-08 requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination on the acquisition date. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. ASU 2021-08 should be applied prospectively to business combinations that occur after the effective date. We adopted ASU 2021-08 as of January 1, 2022 on a prospective basis and applied it to the business combinations completed during 2022. Recent Accounting Pronouncements Not Yet Effective In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP if certain criteria are met to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope . The update provides additional optional guidance on the transition from LIBOR to include derivative instruments that use an interest rate for margining, discounting or contract price alignment. The standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. Additionally, in December 2022, the FASB issued ASU 2022-06, Reference Rate Reform: Deferral of the Sunset Date of Topic 848, which deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024 to align with the amended cessation date of LIBOR. A substantial portion of our indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on our contracts, hedging relationships and other transactions. We will apply the guidance to impacted transactions during the transition period. The adoption of this standard does not have a material impact on our financial position, results of operations or cash flows.

These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. As of December 31, 2022 and 2021, we held certain investment assets and certain liabilities that are required to be measured at fair value on a recurring basis. These investments include money market funds, marketable equity securities and seed capital investments, each of which determines fair value using quoted prices in active markets. Accordingly, the fair value measurements of these investments have been classified as Level 1 in the tables below. Investments for which we elected net asset value as a practical expedient for fair value and investments measured using the fair value measurement alternative are excluded from the table below. Fair value for deferred compensation liabilities that are credited with deemed gains or losses of the underlying hypothetical investments, primarily equity securities, have been classified as Level 1 in the tables below. The following tables present assets and liabilities measured at fair value on a recurring basis (in millions): Fair Value Measurements at Reporting Date Using December 31, 2022 Quoted prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Money market funds (1) $ 674.5 $ 674.5 $ — $ — Seed capital investments (2) 30.6 30.6 — — Marketable equity securities (2) 24.3 24.3 — — Deferred compensation liabilities (3) ( 13.6 ) ( 13.6 ) — — Total $ 715.8 $ 715.8 $ — $ — Fair Value Measurements at Reporting Date Using December 31, 2021 Quoted prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Money market funds (1) $ 1,961.0 $ 1,961.0 $ — $ — Seed capital investments (2) 32.0 32.0 — — Marketable equity securities (2) 40.8 40.8 — — Deferred compensation liabilities (3) ( 21.3 ) ( 21.3 ) — — Total $ 2,012.5 $ 2,012.5 $ — $ — _____________________________________________________ (1) Included in cash and cash equivalents and funds receivable and funds held on behalf of clients on the Consolidated Balance Sheet.

During the years ended December 31, 2022 and 2021, we provided $ 10.0 million and $ 20.0 million, respectively, in seed capital funding to either mutual funds or exchange-traded funds issued by one of our subsidiaries. During the years ended December 31, 2022 and 2021, we redeemed $ 7.6 million and $ 13.5 million, respectively, of our seed capital investments. In February 2020, we entered into a Series A Convertible Share Purchase Agreement with SILAC, Inc. (“SILAC”), pursuant to which we acquired 40 million shares of Series A convertible preferred stock of SILAC for a purchase price of $ 40 million. The investment is classified as a non-marketable equity security without a readily determinable fair value. Mr. William C. Stone, our Chairman of the Board of Directors and Chief Executive Officer, has an economic interest in SILAC and is a member of its board of directors. Accordingly, SILAC is considered a related party. During the year ended December 31, 2022, as a result of an observable price change, we recorded a fair value adjustment of $ 39.5 million to increase the carrying value of SILAC. The fair value adjustment was recorded as an unrealized gain in Other income (expense) on our Consolidated Statements of Comprehensive Income. In each of the years ended December 31, 2022 and 2021, we received a preferred stock dividend from SILAC of $ 8.0 million which is recorded in Other income (expense) on our Consolidated Statements of Comprehensive Income. We have partnership interests in various private equity funds that are not included in the table above. Our investments in private equity funds were $ 15.0 million and $ 15.5 million at December 31, 2022 and 2021 , respectively, of which $ 10.8 million and $ 12.7 million, respectively, were measured using net asset value as a practical expedient for fair value and $ 4.2 million and $ 2.8 million, respectively, were accounted for under the equity method of accounting. The investments in private equity funds represent underlying investments in domestic and international markets across various industry sectors. Generally, our investments in private equity funds are non-transferable or are subject to long holding periods, and withdrawals from the private equity firm partnerships are typically not permitted. The maximum risk of loss related to our private equity fund investments is limited to the carrying value of our investments in the entities.

Also in 2018, we entered into amendments to the Credit Agreement in connection with our acquisitions of Eze and Intralinks, the Term B-5 Loan. On March 22, 2022, in connection with our acquisition of Blue Prism, we entered into an Incremental Joinder to the Credit Agreement with certain of our subsidiaries. Pursuant to the Incremental Joinder, a new $ 650.0 million senior secured incremental term loan B facility (“Term B-6 Loan”) and a new $ 880.0 million senior secured incremental term loan B facility (“Term B-7 Loan” and together with the Term B-6 Loan, the “Incremental Term Loans”) was made available to us, the proceeds of which were used to finance substantially all of the consideration for the acquisition of Blue Prism. The Credit Agreement had a revolving credit facility with a five-year term available for borrowings by SS&C with $ 250.0 million in available commitments (“Revolving Credit Facility”). The Revolving Credit Facility also contained a $ 25 million letter of credit sub-facility. On December 28, 2022, we entered into an amendment (the “Revolving Facility Amendment”) to the Credit Agreement with certain of our subsidiaries. Pursuant to the Revolving Facility Amendment, the Revolving Credit Facility was amended to: (i) extend the maturity date to December 28, 2027, (ii) amend the interest rate provisions to replace LIBOR with Term SOFR as the interest rate benchmark, (iii) increase the aggregate commitments from $ 250.0 million to $ 600.0 million, (iv) increase the letter of credit sub-facility from $ 25.0 million to $ 75.0 million and (v) make certain other revisions fully set forth in the Revolving Facility Amendment. As of December 31, 2022, there was $ 2.5 million utilized of the letter of credit sub-facility and $ 597.5 million available of the Revolving Facility Amendment. SS&C’s and SS&C SARL’s obligations under the Term Loans are guaranteed by (i) our existing and future U.S. wholly-owned restricted subsidiaries, in the case of the Term B-3 Loan, Term B-5 Loan, Term B-6 Loan and the Revolving Credit Facility and (ii) our existing and future wholly-owned restricted subsidiaries, in the case of the Term B-4 Loan and Term B-7 Loan. The obligations of the U.S. loan parties under the Credit Agreement are secured by substantially all of the assets of such persons (subject to customary exceptions and limitations), including a pledge of all of the capital stock of substantially all of the U.S. wholly-owned restricted subsidiaries of such persons (with customary exceptions and limitations) and 65 % of the capital stock of certain foreign restricted subsidiaries of such persons (with customary exceptions and limitations). All obligations of the non-U.S. loan parties under the Credit Agreement are secured by substantially all of our and the other guarantors’ assets (subject to customary exceptions and limitations), including a pledge of all of the capital stock of substantially all of our wholly-owned restricted subsidiaries (with customary exceptions and limitations).

The Credit Agreement also contains customary representations and warranties, affirmative covenants and events of default, subject to customary thresholds and exceptions. In addition, the Credit Agreement contains a financial covenant for the benefit of the Revolving Credit Facility requiring us to maintain a minimum consolidated net secured leverage ratio. In addition, under the Credit Agreement, certain defaults under agreements governing other material indebtedness could result in an event of default under the Credit Agreement, in which case the lenders could elect to accelerate payments under the Credit Agreement and terminate any commitments they have to provide future borrowings. Senior Notes On March 28, 2019, we issued $ 2.0 billion aggregate principal amount of 5.5 % Senior Notes due 2027 (“Senior Notes”), the proceeds of which were used to repay a portion of the outstanding Term B-3 Loan under our Credit Agreement. The Senior Notes are guaranteed, jointly and severally, by Holdings and all of its existing and future domestic restricted subsidiaries that guarantee our existing senior secured credit facilities or certain other indebtedness. The Senior Notes are unsecured senior obligations that are equal in right of payment to all of our existing and future senior unsecured indebtedness. Interest on the Senior Notes is payable on March 30 and September 30 of each year. At any time on or after March 30, 2022, we may redeem some or all of the Senior Notes, in whole or in part, at the redemption prices set forth in the following table, expressed as a percentage of the principal amount, plus accrued and unpaid interest to the redemption date: Redemption Date Price On or after March 30, 2022 104.125 % On or after March 30, 2023 102.750 % On or after March 30, 2024 101.375 % March 30, 2025 and thereafter 100.000 % We may also, from time to time in our sole discretion, purchase, redeem, or retire our existing senior notes, through tender offers, in privately negotiated or open market transactions, or otherwise. The indenture governing the Senior Notes contains a number of covenants that restrict, subject to certain thresholds and exceptions, our ability and the ability of our domestic restricted subsidiaries to incur debt or liens, make certain investments, pay dividends, dispose of certain assets, or enter into transactions with its affiliates. Any event of default under the Credit Agreement that leads to an acceleration of those amounts due also results in a default under the indenture governing the Senior Notes. Debt Issuance Costs and Loss on Extinguishment of Debt We capitalized an aggregate of $ 37.7 million and $ 3.0 million in financing costs during the twelve months ended December 31, 2022 in connection with the Incremental Joinder and Revolving Facility Amendment, respectively . We made additional principal payments prior to their scheduled maturity in 2022, 2021 and 2020, which resulted in a loss on extinguishment of debt of $ 5.5 million, $ 10.9 million and $ 2.2 million, respectively, due to the write-off of a portion of the unamortized capitalized financing fees and the unamortized original issue discount. We accounted for the Pricing Amendment as a debt modification with respect to amounts that were obligations of lenders that exited the syndicate or remained in the syndicate but experienced a change in cash flows of greater than 10 % in accordance with FASB Accounting Standards Codification 470-50, Debt-Modifications and Extinguishments , which resulted in $ 2.8 million loss on extinguishment of debt in 2020. During 2020, we purchased $ 184.8 million principal amount of our Term Loans in privately negotiated transactions, which resulted in a gain on extinguishment of debt of $ 0.8 million.

Stock-based Compensation	12 Months Ended

Equity [Abstract]
Stock-based Compensation	Note 14—Stock-based Compensation In March 2019, our Board of Directors adopted the Second Amended and Restated 2014 Stock Incentive Plan, which amended and restated our Amended and Restated 2014 Stock Incentive Plan (the “Amended 2014 Plan”) (together with the Amended 2014 Plan, the “2014 Plans”), which became effective in May 2019 upon stockholder approval. The 2014 Stock Option Plan authorized stock options to be granted for up to 6.0 million shares of our common stock. The Amended 2014 Plan was adopted with an initial share capacity of 24.0 million shares available for the grant of awards. The Amended 2014 Plan authorizes the issuance of equity awards, including stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) and allows the class of participants to include non-employee directors. The Second Amended and Restated 2014 Stock Incentive Plan was adopted to increase the shares available for equity awards by an additional 34.0 million shares. Under the terms of the 2014 Plans, the exercise price of awards is set on the grant date and may not be less than the fair market value per share on such date. Generally, awards expire ten years from the date of grant. We generally settle RSUs, RSAs, stock appreciation rights (“SARs”), performance-based stock units (“PSUs”), and stock option exercises with newly issued common shares. Restricted Stock Units During the year ended December 31, 2022 , we granted RSUs which generally vest 33.3 % on the first anniversary of the grant and 1/4th of the remaining balance each six months thereafter for two years . We did not grant any RSUs during the years ended December 31, 2021 and 2020. At December 31, 2022, there was approximately $ 119.9 million of unearned non-cash stock-based compensation related to RSUs that we expect to recognize as expense over a remaining period of approximately 2.9 years. At December 31, 2021 , there was no remaining unearned non-cash stock-based compensation related to RSUs. Performance-based Stock Units In July 2021 and March 2022, we granted performance-based stock units at a grant date fair value of $ 75.03 per share and $ 71.89 per sh are, respectively. These awards include established annual earnings per share growth targets and will measure performance against the target over the 2 -year performance period. Performance is measured relative to a 2-year average annual growth rate that is established at the beginning of the cycle and held constant. Participants will only be entitled to receive any portion of the PSUs that are earned if they remain employed through the final determination of the satisfaction of these performance goals. The actual number of units that will be issued ranges from zero , if the threshold level of performance is not achieved, to 200 % of the targeted number of units, if the annual growth rate meets or exceeds a specified level. As of December 31, 2022, the PSUs are not expected to vest. During the year ended December 31, 2022, we recorded a true-up to reverse previously recorded stock-based compensation expense relating to the PSUs. At December 31, 2021 there was approximately $ 25.7 million of unearned non-cash stock-based compensation related to PSUs that we expected to recognize as expense over a remaining period of approximately 1.6 years. Time-based Stock Options and SARs Time-based stock options and SARs generally vest 25 % on the first anniversary of the grant date and 1/36 th of the remaining balance each month thereafter for 36 months. All outstanding time-based stock options and SARs vest upon a change in control, subject to certain conditions. Time-based stock options granted during 2022, 2021 and 2020 have a weighted-average grant date fair valu e of $ 15.26 , $ 22.28 and $ 18.06 per share, respectively, based on the Black-Scholes option pricing model. Compensation expense is recorded on a straight-line basis over the requisite service period. The fair value of time-based stock options vested during the years ended December 31, 2022, 2021 and 2020 was appro ximately $ 102.1 million, $ 103.0 million and $ 81.1 million, respectively. At December 31, 2022 and 2021, there was appr oximately $ 201.6 millio n and $ 270.1 million, respectively, of unearned non-cash stock-based compensation related to time-based stock options that we expect to recognize as expense over a weighted-average remaining period of approxim ately 2.7 years and 2 .8 years, respectively. Performance-based Stock Options In March and December 2021, we granted performance-based stock options (“PSOs”). These awards include established annual earnings per share growth targets and will measure performance against the target over the 3 -year performance period. Performance is measured relative to a 3-year average annual growth rate that is established at the beginning of the cycle and held constant. Participants will only be entitled to receive any portion of the PSOs that are earned if they remain employed through the final determination of the satisfaction of these performance goals. The actual number of options that will be issued ranges from zero , if the threshold level of performance is not achieved, to 200 % of the targeted number of options, if the annual growth rate meets or exceeds a specified level. PSOs granted during 2021 have a weighted-average grant date fair value of $ 21.88 per share, based on the Black-Scholes options pricing model. During the year ended December 31, 2022 and 2021, no PSOs have vested. At December 31, 2022 and 2021, there was approxima tely $ 60.8 million and $ 103.2 mi llion, respectively of unearned non-cash stock-based compensation related to PSOs that we expect to recognize as expense over a remaining period of approximately 2.1 years and 3.1 years, respectively. For the stock-options valued using the Black-Scholes option-pricing model, we used the following weighted-average assumptions: Time-based stock options PSOs 2022 2021 2020 2021 Expected term to exercise (years) 4.0 4.0 4.0 4.0 Expected volatility 35.26 % 36.42 % 34.85 % 36.34 % Risk-free interest rate 3.96 % 1.07 % 0.28 % 1.03 % Expected dividend yield 1.55 % 0.98 % 0.80 % 0.98 % Total Stock Options, RSUs and PSUs The amount of stock-based compensation expense recognized in our Consolidated Statements of Comprehensive Income for the years ended December 31, 2022, 2021 and 2020 was as follows (in millions): Year Ended December 31, 2022 2021 2020 Consolidated Statements of Comprehensive Options RSUs, PSUs Total Options, SARs RSUs, PSUs Total Options, SARs RSUs Total Cost of software-enabled services $ 47.2 $ ( 1.1 ) $ 46.1 $ 39.1 $ 3.7 $ 42.8 $ 32.2 $ 2.3 $ 34.5 Cost of license, maintenance and other related 5.6 ( 0.1 ) 5.5 5.2 0.1 5.3 5.3 — 5.3 Total cost of revenues 52.8 ( 1.2 ) 51.6 44.3 3.8 48.1 37.5 2.3 39.8 Selling and marketing 24.2 ( 1.3 ) 22.9 19.1 1.5 20.6 13.1 0.7 13.8 Research and development 17.2 ( 0.6 ) 16.6 14.2 0.8 15.0 11.1 0.2 11.3 General and administrative 35.1 ( 1.4 ) 33.7 28.4 1.9 30.3 21.4 1.5 22.9 Total operating expenses 76.5 ( 3.3 ) 73.2 61.7 4.2 65.9 45.6 2.4 48.0 Total stock-based compensation expense $ 129.3 $ ( 4.5 ) $ 124.8 $ 106.0 $ 8.0 $ 114.0 $ 83.1 $ 4.7 $ 87.8 The associated future income tax benefit recognized was $ 23.8 million, $ 22.5 million and $ 17.4 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Earnings Per Share [Abstract]
Basic and Diluted Earnings per Share	Note 16—Basic and Diluted Earnings per Share Earnings per share (“EPS”) is calculated in accordance with the relevant standards. Basic EPS includes no dilution and is computed by dividing income available to our common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income by the weighted-average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of stock options, SARs, RSUs and PSUs using the treasury stock method. Common equivalent shares are excluded from the computation of diluted earnings per share if the effect of including such common equivalent shares would be anti-dilutive because their total assumed proceeds exceed the average fair value of common stock for the period. We have two classes of common stock, each with identical participation rights to earnings and liquidation preferences, and therefore the calculation of EPS as described above is identical to the calculation under the two-class method. The following table sets forth the computation of basic and diluted EPS (in millions, except per share amounts): Year Ended December 31, 2022 2021 2020 Net income attributable to SS&C common stockholders $ 650.2 $ 800.0 $ 625.2 Shares attributable to SS&C: Weighted-average common shares outstanding – used in calculation of basic EPS 254.0 255.6 256.4 Weighted-average common stock equivalents – stock options and restricted shares 8.0 11.7 10.2 Weighted-average common and common equivalent shares outstanding – used in calculation of diluted EPS 262.0 267.3 266.6 Earnings per share attributable to SS&C common stockholders – Basic $ 2.56 $ 3.13 $ 2.44 Earnings per share attributable to SS&C common stockholders – Diluted $ 2.48 $ 2.99 $ 2.35 Weighted-average stock options, SARs, RSUs and PSUs representin g 22.2 million, 8.9 million and 9.6 million shares were outstanding for the years ended December 31, 2022, 2021 and 2020 , respectively, but were not included in the computation of diluted EPS because the effect of including them would be anti-dilutive.

In our opinion, we are not involved in any litigation or proceedings that would have a material adverse effect on us or our business. In connection with recent legal proceedings related to the ongoing DST ERISA matters described below, including the arbitration awards, we have recorded an accrued liability of $ 51.5 million. Of this amount, $ 8.1 million and $ 43.4 million were recorded in 2022 and 2021, respectively, to Other income (expense), net on the Consolidated Statements of Comprehensive Income. Due to the inherent uncertainties associated with the resolution of these matters, the ultimate resolution of and any additional potential exposure related to these matters are uncertain at this time. On September 1, 2017, a putative representative action was filed on behalf of the DST 401(k) Profit Sharing Plan (the “Plan”) in the United States District Court for the Southern District of New York, captioned Ferguson, et al v. Ruane Cunniff & Goldfarb Inc., et al. (“Ferguson”), naming as defendants DST, the Compensation Committee of DST’s Board of Directors, the Advisory Committee of the Plan and certain of DST’s present and/or former officers and directors (collectively the “DST Defendants”), alleging breach of fiduciary duties and other violations of the Employee Retirement Income Security Act (“ERISA”). The DST Defendants answered the operative complaint and asserted crossclaims for contribution and/or indemnification against Ruane, Cunniff & Goldfarb Inc. (“Ruane”). On January 9, 2020, Ruane filed an amended answer to the amended complaint and asserted crossclaims for contribution and/or indemnification against DST. On March 8, 2021, the Court entered an order denying without prejudice the plaintiffs’ (the “Ferguson Plaintiffs”) then-pending motions for leave to file a third amended complaint and for class certification, ordering that the parties address the effect, if any, on the Ferguson Plaintiffs’ motions of the March 4, 2021 decision by the United States Court of Appeals for the Second Circuit Court in Cooper v. Ruane Cunniff & Goldfarb Inc. The Ferguson Plaintiffs renewed their motions for leave to file a third amended complaint and for class certification, which motions were fully briefed on May 10, 2021. On August 17, 2021, the Court entered an order certifying a mandatory, non-opt-out class under Federal Rule of Civil Procedure 23(b)(1) that includes all plan participants other than certain plan fiduciaries. Arbitration Claimants, and the Canfield Plaintiffs and Mendon Plaintiffs, each as defined below, filed petitions under Federal Rule of Civil Procedure 23(f) with the Second Circuit on August 30, 2021 and August 31, 2021, respectively, seeking interlocutory review of the Ferguson class certification order, which the Ferguson Plaintiffs and the DST Defendants opposed. The Second Circuit denied the Rule 23(f) petitions on May 24, 2022 and May 25, 2022, respectively. On February 4, 2022, the Ferguson Plaintiffs filed a third amended complaint, which included the class allegations. On March 7, 2022, the DST Defendants and Ruane each filed answers to the Ferguson Plaintiffs’ third amended complaint and reasserted their respective cross-claims. On August 23, 2021, the DST Defendants moved for a temporary restraining order and preliminary injunction against other proceedings, including the below-described arbitrations, which arise out of or relate to the allegations in Ferguson. Following briefing, on November 18, 2021, the Court granted the DST Defendants’ motion and entered a preliminary injunction enjoining the Ferguson class members, including Arbitration Claimants, from instituting new actions or litigating in arbitration or other proceedings against the DST Defendants matters arising out of or relating to the facts or transactions alleged in the Ferguson amended complaint. On November 18, 2021, the Court also ordered the DST Defendants and Arbitration Claimants to submit briefing regarding how the arbitration awards that have been entered against the DST Defendants should be handled in light of the Court’s class certification order and preliminary injunction. On December 15, 2021, Arbitration Claimants and the Canfield Plaintiffs and Mendon Plaintiffs filed appeals of the Court’s preliminary injunction. On December 23, 2021, the DST Defendants, Arbitration Claimants, and the Ferguson Plaintiffs submitted briefs concerning the treatment of the arbitration awards that have been entered against the DST Defendants, and further briefing by the DST Defendants and Arbitration Claimants was submitted on January 26, 2022. On December 31, 2021, Arbitration Claimants moved by order to show cause for an immediate stay of the preliminary injunction pending their appeal to the Second Circuit. On January 3, 2022, the Court denied Arbitration Claimants’ motion for an immediate stay and ordered the DST Defendants to show cause as to why the Court should not issue a stay of the preliminary injunction pending appeal. On February 3, 2022, the Court denied Arbitration Claimants’ motion to stay the preliminary injunction pending appeal. In the same order, the Court held that it would determine the status of the arbitration awards already entered against DST at final judgment in the Ferguson action, either after trial or after settlement. On February 4, 2022, Arbitration Claimants filed a motion in the Second Circuit to stay the preliminary injunction pending their appeal of the Court’s preliminary injunction. On June 7, 2022, the Second Circuit denied Arbitration Claimants’ motion to stay the preliminary injunction pending appeal. On February 8, 2022, Arbitration Claimants and the Canfield Plaintiffs and Mendon Plaintiffs noticed an appeal of the Court’s February 3, 2022 order. The February 8, 2022 appeal was consolidated with the December 15, 2021 appeal of the preliminary injunction. On May 17, 2022, Arbitration Claimants and the Canfield Plaintiffs and Mendon Plaintiffs filed their opening brief in the consolidated appeals. The DST Defendants filed their answering brief on September 15, 2022, and the reply was filed on October 20, 2022. On January 30, 2023, the Second Circuit calendared oral argument for the appeal of the Court's preliminary injunction for April 20, 2023. This appeal remains pending. On July 10, 2020, the Ferguson Plaintiffs and the DST Defendants reached an agreement in principle to settle the class claims for $ 27 million, subject to the occurrence of certain conditions, including: Court certification of a “non‑opt-out” class in the case that includes as class members all participants of the Plan, Court approval of the settlement in accordance with applicable law and the satisfactory resolution of claims made by certain other litigants. On September 18, 2020, the parties submitted a letter to the Court disclosing that the Ferguson Plaintiffs and Ruane also had reached a settlement in principle, subject to Court approval. The Ferguson Plaintiffs and the DST Defendants entered into a settlement agreement dated January 8, 2021 memorializing the terms of their proposed settlement, which was filed by the Ferguson Plaintiffs with the Court on the same date. On January 12, 2021, the Ferguson Plaintiffs moved for preliminary approval of the settlement with the DST Defendants, as well as preliminary approval of a separate settlement reached between the Ferguson Plaintiffs and Ruane. Arbitration Claimants and the U.S. Department of Labor (“DOL”) objected to various aspects of those settlements in filings dated January 15, 2021, January 27, 2021, and February 5, 2021. On August 17, 2021, the Court denied the Ferguson Plaintiffs’ motion for preliminary approval of the settlement on the terms proposed. On November 10, 2022, the Ferguson parties filed a notice of settlement and joint motion to stay the proceedings. The notice informed the Court that the parties had reached a settlement in principle to settle the class claims (as discussed above, the class excludes certain plan fiduciaries), and the joint motion requested a stay while the parties sought to finalize their agreement and prepare an application for Court approval of the contemplated settlement. On November 18, 2022, the Court entered an order staying the Ferguson action for 30 days. On December 19, 2022, the Ferguson parties filed a joint motion to stay the proceedings for an additional 30 days, which the Court granted on January 9, 2023, staying the proceedings until February 8, 2023. On February 8, 2023, the Ferguson parties filed a joint motion to stay the proceedings for an additional 45 days, which the Court granted on February 21, 2023, staying the proceedings until April 7, 2023. On September 28, 2018, a complaint was filed in the United States District Court for the Southern District of New York captioned Robert Canfield, et al. v. SS&C Technologies Holdings, Inc., et al., on behalf of five individual plaintiffs (the “Canfield Plaintiffs”). On November 5, 2018, a similar complaint was filed in the United States District Court for the Southern District of New York captioned Mark Mendon, et al. v. SS&C Technologies Holdings, Inc., et al., on behalf of two individual plaintiffs (the “Mendon Plaintiffs”). These complaints name as defendants SS&C, the DST Defendants, and Ruane. The underlying claim in each complaint is the same as in the above-described Ferguson matter, with the exception that these actions purport to be brought as individual actions and not putative class actions. On July 10, 2020, the Court entered an order granting the DST Defendants’ motion to disqualify plaintiffs’ counsel in the Canfield and Mendon actions. On March 17, 2021, the Court issued an opinion and order denying the DST Defendants’ motion to disqualify counsel from the arbitrations described below. On April 12, 2021, the Canfield Plaintiffs and Mendon Plaintiffs filed notices of voluntary dismissal dismissing their claims against Ruane with prejudice, which were entered by the Court on April 13, 2021. On April 22, 2021, the DST Defendants filed motions to dismiss the Canfield and Mendon actions. Those motions were fully briefed on May 28, 2021. On November 19, 2021, the Court dismissed the Canfield and Mendon actions. On December 17, 2021, the Canfield Plaintiffs and Mendon Plaintiffs appealed the Court’s November 19, 2021 orders dismissing their respective actions to the Second Circuit. On May 17, 2022, the Canfield Plaintiffs and Mendon Plaintiffs filed their opening briefs in those appeals. The DST Defendants filed their answering briefs on September 15, 2022. The Canfield Plaintiffs and Mendon Plaintiffs filed their reply briefs on October 20, 2022. On January 30, 2023, the Second Circuit calendared oral argument for the appeals of the Court's dismissal of the Canfield and Mendon actions for April 20, 2023. These appeals remain pending. On October 8, 2019, a substantially similar action to the above-described Ferguson, Canfield, Mendon and below-described arbitration matters captioned Scalia v. Ruane, Cunniff & Goldfarb Inc. was filed by the DOL in the United States District Court for the Southern District of New York naming as defendants DST, the Advisory Committee of the Plan, the Compensation Committee of DST’s Board of Directors and certain of DST’s former officers and directors, and alleging that the DST Defendants breached fiduciary duties in violation of ERISA in connection with the Plan. The complaint also names as defendants Ruane and its former Chairman and Chief Executive Officer Robert D. Goldfarb. In the complaint, the DOL seeks disgorgement, damages and any other appropriate injunctive or equitable relief. The DST Defendants moved to dismiss the complaint on December 4, 2020 on the ground that the DOL’s complaint is time-barred. Other defendants also filed motions to dismiss on the same and other grounds. Briefing on the motions to dismiss was completed on February 5, 2021. On March 28, 2022, the court denied Defendants’ motions to dismiss, and Martin J. Walsh was substituted for Eugene Scalia as the plaintiff. On April 11, 2022, the DST Defendants answered the DOL’s complaint. DST, the Advisory Committee of the Plan, and the Compensation Committee of DST’s Board of Directors have been named in 579 substantially similar individual demands for arbitration to date, by former and current DST employees demanding arbitration under the DST Employee Arbitration Program and Agreement (the “Arbitration Claimants”). The underlying claim in each is the same as in the above-described Ferguson matter, with the exception that the arbitrations purport to be brought as individual actions. On November 24, 2021, in light of the preliminary injunction entered in Ferguson discussed above, the American Arbitration Association ceased administration of the arbitrations brought by members of the Ferguson class, which includes all of the Arbitration Claimants with the exception of certain former Plan fiduciaries. As of November 24, 2021, 557 demands for arbitration had been submitted to the American Arbitration Association (the “AAA”). As of the date on which the preliminary injunction was entered, those individual arbitrations were at various stages depending on the particular proceeding. Certain of those arbitrations had resulted in awards against DST and others had resulted in decisions finding no liability as against DST. Many of those decisions were subject to further appeal within the AAA. Certain of the arbitration proceedings had been resolved in whole or in part by settlement. Since November 24, 2021, the AAA has administered only those arbitration proceedings associated with claimants who are not members of the Ferguson class, certain of which have resulted in awards against DST. Between August 20, 2021 and November 17, 2021, counsel for Arbitration Claimants filed 177 motions to confirm certain of the arbitration awards. DST filed responses to those motions. Between October 4 and December 22, 2021, the Western District of Missouri issued orders confirming those 177 arbitration awards and entering judgments against DST. DST appealed those judgments to the Eighth Circuit. On November 20, 2021, DST requested that the Eighth Circuit stay the pending appeals in light of the preliminary injunction entered in Ferguson. On December 3, 2021, the Eighth Circuit ordered the parties to brief DST’s stay request, and on January 3, 2022, the Eighth Circuit declined to stay the briefing schedule on the pending appeals and consolidated those appeals. DST filed its opening brief in the Eighth Circuit on March 24, 2022. Arbitration Claimants filed their opposition brief on April 26, 2022, and DST filed its reply brief on May 18, 2022. The Eighth Circuit heard oral argument on June 14, 2022. On November 28, 2022, the Eighth Circuit vacated the judgments confirming the 177 arbitration awards and remanded those actions to the Western District of Missouri to determine whether the district court has subject-matter jurisdiction and whether the district court should transfer the cases to the Southern District of New York. On December 14, 2022, the parties submitted simultaneous briefing to the Western District of Missouri regarding transfer. On November 9, 2021, counsel for Arbitration Claimants filed in the Western District of Missouri a petition to compel arbitration captioned Addison v. DST Systems, Inc. (the “Addison Petition”) on behalf of 155 Arbitration Claimants, which DST opposed. On September 15, 2022, the Western District of Missouri dismissed the Addison Petition without prejudice, subject to that action being reopened after the Eighth Circuit’s rulings on DST’s appeals of the 177 orders confirming arbitration awards. We continue to vigorously defend these matters. On November 11, 2020, DST, the Compensation Committee of DST’s Board of Directors, and the Advisory Committee of the Plan as plaintiffs filed a complaint in the United States District Court for the Southern District of New York against Ruane, certain of its related entities, and certain of its current and former employees. The complaint asserts claims for contribution, indemnification, and breach of contract arising out of Ruane’s management of the Plan’s investments and claims for actual and constructive fraudulent conveyances. On May 24, 2021, Defendant Robert Goldfarb filed an answer to the complaint. On December 17, 2021, the remaining defendants filed a motion to dismiss the DST plaintiffs’ complaint. On July 27, 2022, the Court denied without prejudice the pending motion to dismiss, and ordered the parties to submit by October 3, 2022 a joint status report with a new briefing schedule on the motion. On October 3, 2022, the parties filed a joint status report with a new briefing schedule on the motion, which the court approved on October 4, 2022. On December 16, 2022, and January 13, 2023, the parties filed joint motions to stay the proceedings, which were granted on January 31, 2023, staying proceedings until February 8, 2023. On February 8, 2023, the parties filed a joint motion to stay the proceedings for an additional 45 days. This motion remains pending.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, collectability of accounts receivable, valuation of non-marketable securities, costs to complete certain contracts, valuation of acquired assets and liabilities, valuation of stock options, income tax accruals and the value of deferred tax assets and liabilities. Estimates are also used to determine the remaining economic lives and carrying value of fixed assets, goodwill and intangible assets. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of us and our subsidiaries. All significant accounts, transactions and profits between the consolidated companies have been eliminated in consolidation. We consolidate any entity in which we have a controlling financial interest. Under the voting interest model, generally the investor that has voting control (usually more than 50 % of an entity’s voting interests) consolidates the entity. Under the variable interest entity (“VIE”) model, the party that has the power to direct the entity’s most significant economic activities and the ability to participate in the entity’s economics consolidates the entity. An entity is considered a VIE if it possesses any one or more of the following characteristics: 1) the entity is thinly capitalized; 2) residual equity holders do not control the entity; 3) equity holders are shielded from economic losses; 4) equity holders do not participate fully in an entity’s residual economics; and 5) the entity was established with non-substantive voting interests. We have consolidated one VIE since we are the primary beneficiary as discussed in Note 12 below. Our investments in private equity funds meet the definition of a VIE; however, the private equity fund investments are not consolidated as we do not have the power to direct the entities’ most significant economic activities. We are the lessee in a series of operating leases covering a large portion of our Kansas City, Missouri-based leased office facilities. The lessors are generally joint ventures (in which we have 50 % ownership) that have been established specifically to purchase, finance and engage in leasing activities with the joint venture partners and unrelated third parties. Our analysis of our real estate joint ventures for all periods presented indicate that none qualified as a VIE and, accordingly, they have not been consolidated. Unconsolidated investments in entities over which we do not have control but have the ability to exercise influence over operating and financial policies, if any, are accounted for under the equity method of accounting. Earnings and losses from such investments are recorded on a pre-tax basis, if any.
Revenue Recognition	Revenue Recognition We account for the recognition of our revenue in accordance with the relevant accounting literature, primarily Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (ASC 606). Our sources of revenue are described below. Software-enabled Services Revenue We primarily offer software-enabled outsourcing services in which we utilize our own software to offer comprehensive fund administration services for alternative investment managers, including fund manager services, transfer agency services, funds-of-funds services, tax processing and accounting. We also use our own software applications to provide healthcare organizations a variety of medical and pharmacy benefit solutions to satisfy their information processing, quality of care, cost management concerns and payment integrity programs. Our healthcare solutions include claims adjudication, benefit management, care management, business intelligence and other ancillary services. We also offer subscription-based on-demand software applications that are managed and hosted at our facilities. The software-enabled services arrangements provide an alternative for clients who do not wish to install, run and maintain complicated financial software. Under these arrangements, the client does not have the right to take possession of the software, rather, we agree to provide access to our applications, remote use of our equipment to process transactions, access to client’s data stored on our equipment and connectivity between our environment and the client’s computing systems. Software-enabled services are generally provided under contracts with initial terms of one to five years that require monthly or quarterly payments, and are subject to automatic annual renewal at the end of the initial term unless terminated by either party. In software-enabled services arrangements, the arrangement is a single performance obligation or a stand-ready performance obligation, which in either case is comprised of a series of distinct services that are substantially the same and have the same pattern of transfer to the customer (i.e. distinct days or months of service). We apply a measure of progress (typically time-based) to any fixed consideration and allocate variable consideration to the distinct periods of service based on usage or summarization of account information. These variable payments relate specifically to our efforts to perform the services in the period in which the fee applies. This variability is solely attributed to and resolved as a result of the transfer of these services; these fees are independent of the transfer of past or future goods or services. These fees meet the allocation objective of Accounting Standards Codification (“ASC”) 606 because they represent the amount of consideration we are entitled to for these services. Revenue is generally recognized over the period the services are provided, which results in revenue recognition that corresponds with the value to the client of the services transferred to date relative to the remaining services promised. For our software-enabled services contracts, which are cancelable with 90 days’ notice or meet the allocation objective for a series of performance obligations under ASC 606, we have not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or when we expect to recognize this revenue. License, Maintenance and Related Revenue Agreements We generate revenues in the form of software license fees and related maintenance and services fees. License fees include perpetual license fees and term license fees that differ mainly in the duration over which the customer benefits from the software. Maintenance and services primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available) and, in some cases, professional services which focus on both deployment and training our customers to fully leverage the use of our products. Under ASC 606, we identify a contract with a customer, we identify the performance obligations in the contract, we determine the transaction price, we allocate the transaction price to each performance obligation in the contract and recognize revenues when (or as) we satisfy a performance obligation. Software license performance obligations are functional intellectual property that are distinct as the user can benefit from the software on its own as defined under ASC 606. Software license revenues are recognized at the point of time when the software license has been delivered. Term license fees are typically due in annual installments at the beginning of each annual period and we record a contract asset for amounts recognized as revenue in excess of amounts billed. We recognize maintenance revenues ratably over the term of the underlying contract term because we transfer control evenly by providing a stand-ready service. The term of the maintenance contract on a perpetual license is usually one year and the duration of a term license contract is usually between one to five years . Renewals of maintenance contracts create new performance obligations that are satisfied over the term with the revenues recognized ratably over the term. Revenues from professional services consist mostly of services provided on a time and materials basis. The performance obligations are satisfied, and revenues are recognized, over time as the services are provided. In contracts with multiple performance obligations, we account for individual performance obligations separately if they are distinct. We allocate the transaction price to each performance obligation based on our relative standalone selling price out of total consideration of the contract. Standalone selling price is determined utilizing observable prices to the extent available. If the standalone selling price for a performance obligation is not directly observable, we estimate it maximizing the use of observable inputs. For maintenance and support, we determine the standalone selling price based on the price at which we separately sell a renewal contract and the economic relationship between licenses and maintenance. We primarily determine the standalone selling price for sales of license arrangements using the residual approach. In situations when the software license and the right to unspecified product upgrades are not distinct in the context of the contract, they are combined into a single performance obligation and revenue is recognized on a straight line basis over the contract duration. For professional services, we determine the standalone selling prices based on the price at which we separately sell those services. We occasionally enter into license agreements requiring significant customization of our software that are not material to our results of operations. We account for the license and professional service fees under these agreements as a single performance obligation, recognized over time using an input method during the development of the license. This method requires estimates to be made for costs to complete the agreement utilizing an estimate of development man-hours remaining. Revenue is recognized each period based on the hours incurred to date compared to the total hours expected to complete the project. Due to uncertainties inherent in the estimation process, it is at least reasonably possible that completion costs will be revised. Such revisions are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are determined on a contract-by-contract basis, and are made in the period in which such losses are first estimated or determined. We do not account for significant financing components if the period between when we transfer the promised product or service to the client and when the client pays for that product or service will be one year or less. We record revenue net of any taxes assessed by governmental authorities. Accounts Receivable, net is primarily comprised of billed and unbilled receivables for which we have an unconditional right to consideration, net of an allowance for credit losses.
Costs of Revenues	Costs of Revenues Costs of revenues include all costs, including depreciation and amortization, incurred to produce revenues. Incremental costs of obtaining a contract (e.g., sales commissions) are capitalized and amortized on a basis consistent with the pattern of transfer of goods or services to the customer to which the asset relates over the expected customer relationship period if we expect to recover those costs. The expected customer relationship period is determined based on average historical customer relationship periods, including expected renewals. Expected renewal periods are only included in the expected customer relationship period if commission amounts paid upon renewal are not commensurate with amounts paid on the initial contract. Incremental costs of obtaining a contract include only those costs we incur to obtain a contract that we would not have incurred if the contract had not been obtained. We have determined that certain commissions programs meet the requirements to be capitalized. Certain sales commissions associated with multi-year contracts are subject to an employee service requirement. As an action other than each party approving the contract is required to trigger payment of these sales commissions, they are not considered incremental costs to obtain a contract and are expensed as incurred. These costs are included in selling and marketing. We expense sales commissions as incurred when the amortization period would have been one year or less.
Research and Development	Research and Development Research and development costs associated with computer software are charged to expense as incurred. Capitalization of internally developed computer software costs in the case of software to be sold begins upon the establishment of technological feasibility based on a working model. Capitalization of internally developed computer software costs in the case of internal use software begins when management authorizes and commits funding to a project and the preliminary design stage has been completed. Our policy is to amortize these costs upon a product’s general release to the client. Amortization of capitalized software costs is calculated by the greater of (a) the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or (b) the straight-line method over the remaining estimated economic life of the product, including the period being reported on, typically two to five years .
Stock-based Compensation	Stock-based Compensation Using the fair value recognition provisions of relevant accounting literature, stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the appropriate service period. Determining the fair value of stock-based awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of our stock price. In addition, for stock-based awards where vesting is dependent upon achieving certain operating performance goals, we estimate the likelihood of achieving the performance goals. Differences between actual results and these estimates could have a material effect on our financial results. Forfeitures are accounted for as they occur. A deferred income tax asset is recorded over the vesting period as stock compensation expense is recorded for non-qualified option awards. The realizability of the deferred tax asset is ultimately based on the actual value of the stock-based award upon exercise. If the actual value is lower than the fair value determined on the date of grant, then there would be an income tax expense for the portion of the deferred tax asset that is not realizable.
Income Taxes	Income Taxes We account for income taxes in accordance with the relevant accounting literature. An asset and liability approach is used to recognize deferred tax assets and liabilities for the future tax consequences of items that are recognized in our financial statements and tax returns in different years. A valuation allowance is established against net deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. We account for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50 % likely of being realized upon ultimate settlement. We consider many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid marketable securities with original maturities of three months or less at the date of acquisition to be cash equivalents.
Funds Receivable and Funds Held on Behalf of Clients	Funds Receivable and Funds Held on Behalf of Clients We hold client funds on behalf of transfer agency clients and pharmacy processing clients in connection with providing our data processing services. End-of-day available client bank balances for full service mutual fund transfer agency clients are invested overnight in credit quality government money market funds, bank deposits and repurchase agreements. Invested balances are returned to the full service mutual fund transfer agency clients’ accounts the following business day. Funds received from clients for the payment of pharmacy claims incurred by its members are invested in credit quality government money market funds, bank deposits and repurchase agreements until the paid claims are settled. Client funding receivables represent amounts due to us for pharmacy claims paid in advance of receiving client funding and for pharmacy claims processed for which client funding requests have not been made. Funds held on behalf of clients in the form of cash, cash equivalents and certificates of deposit with a maturity of less than twelve months are included in funds receivable and funds held on behalf of clients in the Consolidated Balance Sheet. Funds held on behalf of clients in the form of certificates of deposit with a maturity of greater than twelve months are classified as investments on the Consolidated Balance Sheets. All funds held on behalf of clients represent assets that are restricted for use. We have included funds held on behalf of clients that meet the definition of restricted cash and restricted cash equivalents in the beginning and end of period balances in the Consolidated Statements of Cash Flows. Cash inflows and outflows related to investment of funds held on behalf of clients are reported on a gross basis as “Investments in securities” and “Proceeds from sales / maturities of investments” in the investing section of the Consolidated Statements of Cash Flows.
Client Funds Obligations	Client Funds Obligations Client funds obligations represent funds owed to full service mutual fund transfer agency clients for cash balances invested overnight, and our contractual obligations to satisfy client pharmacy claim obligations that are recorded on the balance sheet when incurred, generally after we have processed a claim on behalf of its pharmacy clients.
Restricted Cash	Restricted Cash Restricted cash primarily includes amounts held by a bank as security for letters of credit issued due to lease requirements for office space. The letters of credit are expected to be renewed within the next twelve months, and as such, the restricted cash is classified as a current asset on the Consolidated Balance Sheets.
Investments and Unconsolidated Affiliates	Investments and Unconsolidated Affiliates We hold various investments, including investments in marketable securities, non-marketable securities and partnership interests in private equity funds, joint ventures and other similar entities. The equity method of accounting is used for investments in entities, partnerships and similar interests (including investments in private equity funds where we are a limited partner and hold a greater than 5 % partnership interest in the fund) in which we have significant influence but do not control. Under the equity method, we recognize income or losses from our pro-rata share of these unconsolidated affiliates’ net income or loss, which changes the carrying value of the investment of the unconsolidated affiliate. We measure equity investments in marketable securities, seed capital investments and other investments, other than those accounted for under the equity method of accounting or those that result in consolidation of the investee, at fair value, with changes in the fair value recognized in earnings. We use net asset value as a practical expedient for the fair value of partnership interests in private equity funds that are not accounted for under the equity method of accounting. Investments in non-marketable equity securities that do not have readily determinable fair values and do not qualify for the practical expedient to measure the investment using a net asset value per share are recorded using the measurement alternative in ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities . These investments are recorded at cost, less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. At each reporting period, we assess if these investments continue to qualify for this measurement alternative. Impairment is recorded when there is evidence that the expected fair value of the investment has declined to below the recorded cost. We have certain investments in unconsolidated affiliates accounted for under the equity method of accounting in which our carrying value exceeds our proportionate share of net assets of the unconsolidated affiliate. The total investment in unconsolidated affiliates, including basis differences, is included in unconsolidated affiliates on the Consolidated Balance Sheet. We record our proportionate share of the results of the unconsolidated affiliates and amortization expense related to basis differences in equity in earnings of unconsolidated affiliates, net on the Consolidated Statements of Comprehensive Income.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation of property, plant and equipment is calculated using a combination of straight-line and accelerated methods over the estimated useful lives of the assets as follows: Description Useful Life Land – Buildings 40 years Building improvements Shorter of 40 years or remaining life of the building Equipment and software 3 - 5 years Furniture and fixtures 7 - 10 years Leasehold improvements Shorter of lease term or estimated useful life Maintenance and repairs are expensed as incurred. The costs of sold or retired assets are removed from the related asset and accumulated depreciation accounts and any gain or loss is included in the Consolidated Statements of Comprehensive Income.
Leases	Leases We account for our leases in accordance with ASC 842. We determine if our contractual agreements contain a lease at inception. A lease is identified when a contract allows us the right to control an identified asset for a period of time in exchange for consideration. Our lease agreements consist primarily of operating leases for office space. Our operating leases are included on the Consolidated Balance Sheets as operating lease assets and operating lease liabilities, under ASC 842. An operating lease asset represents our right to use an underlying asset over the term of a lease while an operating lease liability represents our obligation to make lease payments arising from the lease. Operating lease liabilities are recognized at the commencement date at the present value of the base minimum rent payments. Operating lease assets are also recognized at the commencement date as the total operating lease liability adjusted for prepaid rents, deferred rent liabilities and lease fair value adjustments that existed under ASC 840. As most of our leases do not provide an implicit rate, we use our estimated secured incremental borrowing rate within each of the significant geographic regions in which we operate based on the information available at lease commencement date in determining the present value of lease payments. Our lease agreements typically do not contain variable lease payments, residual value guarantees or restrictive covenants. Many of our leases include the option to renew, however we do not believe it is reasonably certain that we will exercise the options as each individual lease is evaluated and further negotiated prior to the end of the current lease terms. Generally, our lease agreements include required separate payments for non-lease components (e.g. payments for common area maintenance, real estate taxes and/or utilities) which are expensed as incurred. We do have certain lease agreements that contain bundled minimum payments for lease components (e.g. payments for rent) and non-lease components. In these situations, we have applied the practical expedient available under ASC 842 to not separate the lease and non-lease components for purposes of the right-of-use asset and lease payment obligation calculations.
Goodwill and Intangible Assets	Goodwill and Intangible Assets We test goodwill annually for impairment as of December 31 st (and in interim periods if certain events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount). We have completed the required impairment tests for goodwill and have determined that no impairment existed as of December 31, 2022 or 2021 . As of December 31, 2022 and 2021 , we have two reporting units, one is our health business and the other includes the rest of our operations. Our impairment analysis indicated that the fair value significantly exceeded the carrying value of each of our reporting units as of December 31, 2022 and 2021 . We measure the fair value of our reporting units utilizing the income method. Significant judgment is required to determine appropriate revenue growth rates and estimate the fair value of our reporting units. There were no other indefinite-lived intangible assets as of December 31, 2022 or 2021. Customer relationships, completed technology, trade names and other identifiable intangible assets are amortized over lives ranging from two to 17 years . Completed technology and customer relationships are amortized each year based on the ratio that the projected cash flows for the intangible assets bear to the total of current and expected future cash flows for the intangible asset. Trade names are amortized on a straight line basis.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We evaluate the recoverability of our long-lived assets when there is evidence that events or changes in circumstances have made recovery of the carrying value of the asset or asset group unlikely. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset or asset group. We have identified no such impairment losses in the years ended December 31, 2022 and 2021 .
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash, cash equivalents, marketable securities and trade receivables. We have cash investment policies that limit investments to investment grade securities. Concentrations of credit risk, with respect to trade receivables, are limited due to the fact that our client base is highly diversified. As of December 31, 2022 and 2021 , we had no significant concentrations of credit.
International Operations and Foreign Currency	International Operations and Foreign Currency The functional currency of each foreign subsidiary is generally the local currency. Accordingly, assets and liabilities of foreign subsidiaries are translated to U.S. dollars at period-end exchange rates, and capital stock accounts are translated at historical rates. Revenues and expenses are translated using the average rates during the period. The resulting translation adjustments are excluded from net earnings and accumulated as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included within other income (expense) in the Consolidated Statements of Comprehensive Income in the periods in which they occur.
Comprehensive Income (Loss)	Comprehensive Income Our comprehensive income consists of net income, foreign currency translation adjustments, a defined benefit pension plan and our proportionate share of the change in value of an interest rate swap agreement that one of our unconsolidated affiliates is a party to, which are presented in the Consolidated Statements of Comprehensive Income, net of tax and reclassifications to earnings. The accumulated balance of other comprehensive income is reported separately from retained earnings and additional paid-in capital in the stockholders’ equity section of the Consolidated Balance Sheets. Total comprehensive income consists of net income and other accumulated comprehensive (loss) income disclosed in the equity section of the Consolidated Balance Sheets.
Treasury Stock	Treasury Stock Treasury stock purchases are accounted for under the cost method and are included as a deduction from equity in the stockholders’ equity section of the Consolidated Balance Sheets. Under the cost method, the price paid for the stock is charged to the treasury stock account. We use the average cost method to reduce the value of the treasury stock account if treasury stock is re-issued.
Contingencies	Contingencies Loss contingencies from legal proceedings and claims may occur from government investigations, shareholder lawsuits, contractual claims, tax and other matters. Accruals are recognized when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. Gain contingencies are not recognized until realized. Legal fees are expensed as incurred.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities From Contracts with Customer. ASU 2021-08 requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination on the acquisition date. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. ASU 2021-08 should be applied prospectively to business combinations that occur after the effective date. We adopted ASU 2021-08 as of January 1, 2022 on a prospective basis and applied it to the business combinations completed during 2022.
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP if certain criteria are met to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope . The update provides additional optional guidance on the transition from LIBOR to include derivative instruments that use an interest rate for margining, discounting or contract price alignment. The standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. Additionally, in December 2022, the FASB issued ASU 2022-06, Reference Rate Reform: Deferral of the Sunset Date of Topic 848, which deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024 to align with the amended cessation date of LIBOR. A substantial portion of our indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on our contracts, hedging relationships and other transactions. We will apply the guidance to impacted transactions during the transition period. The adoption of this standard does not have a material impact on our financial position, results of operations or cash flows.
