Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company from time to time enters into contracts containing indemnification obligations of the Company. These obligations may require the Company to make payments to another party upon the occurrence of certain events including the failure by the Company to meet its performance obligations under the contract. These contractual indemnification provisions are often standard contractual terms of the nature customarily found in the type of contracts entered into by the Company. In many cases, there are no stated or notional amounts included in the indemnification provisions. There are no amounts reflected on the Consolidated Balance Sheets as of September 30, 2022 and December 31, 2021 related to these indemnifications. Stanford Trust Company Litigation There has been no material change to the status of the litigations related to the Stanford Trust Company matters or the Company’s expectations with respect to such matters as previously reported in the Company’s quarterly report on Form 10-Q as filed with the Commission on April 25, 2022. SS&C Advent Matter On February 28, 2020, SEI Global Services, Inc. (SGSI), a wholly-owned subsidiary of the Company, filed a complaint under seal in the United States District Court for the Eastern District of Pennsylvania against SS&C Advent (Advent) and SS&C Technologies Holdings, Inc. (SS&C) alleging that SS&C and Advent breached the terms of the contract between the parties and asking the Court to hold SS&C and Advent to their bargained-for obligations (the Advent Matter). In addition to Breach of Contract, the complaint also included counts for Declaratory Judgment, Tortious Interference with Existing and Prospective Contractual Relations, Violation of the New York General Business Law Section 349, Violations of Section 2 of the Sherman Antitrust Act, Promissory Estoppel and Breach of the Covenant of Good Faith and Fair Dealing. SGSI sought various forms of relief, including declaratory judgment, specific performance under the contract, and monetary damages, including punitive damages, treble damages and attorney’s fees. On October 23, 2020, the federal court dismissed SEI’s federal antitrust claims but declined to rule on the state law claims. SGSI appealed the dismissal of the federal anti-trust claims to the Third Circuit Court of Appeals. On June 30, 2022, the Third Circuit Court of Appeals issued an order denying SGSI’s appeal of the District Court’s ruling. Beginning in October 23, 2020, Advent and SGSI litigated the remaining breach of contract, breach of the implied duty of good faith and fair dealing, and tortious interference with contract claims in New York State Court. New York State Court rulings during the litigation of the Advent Matter affirmed the validity and enforceability of SGSI’s perpetual license to Advent’s Geneva software. On September 26, 2022, the parties entered into a confidential settlement agreement of the outstanding issues being litigated in the Advent Matter. On October 3, 2022, Judge Borrok of the New York State Court issued an Order dismissing the Advent Matter in connection with the settlement agreement. Other Matters The Company and certain of its subsidiaries are party to various other examinations, investigations, actions and claims arising in the normal course of business that the Company does not believe are material. The Company believes that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial position or the manner in which the Company conducts its business. Currently, the Company does not believe the amount of losses associated with these matters can be estimated. While the Company does not believe that the amount of such losses will, when liquidated or estimable, be material to its financial position, the assumptions may be incorrect and any such loss could have a material adverse effect on the Company's results of operations or the manner in which the Company conducts its business in the period(s) during which the underlying matters are resolved.
