COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Letters of Credit and Guarantees - We provide letters of credit to landlords (lessors) of our leased premises in lieu of cash security deposits, which totaled $3.2 million and $3.2 million at June 30, 2025 and December 31, 2024, respectively. In addition, we provide license bonds to various state agencies to meet certain licensing requirements. The amount of license bonds outstanding was $2.2 million and $2.2 million at June 30, 2025 and December 31, 2024, respectively. Legal Proceedings - On December 19, 2016, CBIZ Operations, Inc. ("CBIZ Operations") was named as a defendant in a lawsuit filed by Zotec Partners, LLC (“Zotec”) in the Marion County Indiana Superior Court. After various amendments, the lawsuit asserted claims under Indiana law for securities, statutory and common law fraud or deception, unjust enrichment, breach of contract, and vicarious liability against CBIZ Operations and a former employee of CBIZ MMP in connection with the sale of the CBIZ MMP medical billing practice to Zotec. The plaintiff claimed that CBIZ Operations had a duty to disclose the fact, unknown to employees of CBIZ Operations at the time of the transaction, that the former employee of CBIZ MMP had a financial arrangement with a Zotec vendor at the time CBIZ Operations sold CBIZ MMP to Zotec. The plaintiff sought damages of up to $177.0 million out of the $200.0 million transaction price. Trial was held in October 2021. The jury found in favor of CBIZ on all fraud, contract and other claims before it. On November 14, 2022, the trial court ruled in favor of CBIZ and against Zotec’s claim for statutory securities fraud. The court also ruled in favor of CBIZ on its counterclaim for indemnification under contract. The trial court conducted a hearing on December 12, 2023, to consider evidence regarding the amount of damages owed by Zotec to CBIZ on the counterclaim. On March 12, 2024, the court awarded CBIZ $3.1 million on its counterclaim. On April 10, 2024, Zotec filed a notice of appeal. On April 8, 2025, the Court of Appeals affirmed the trial court's dismissal of the securities fraud claim against CBIZ. The Court of Appeals reversed the award to CBIZ on its counterclaim. Both CBIZ and Zotec opted against appealing this decision, rendering the decision final. On November 10, 2023, CBIZ was named as a defendant in a putative class action lawsuit in the United States District Court for the District of Massachusetts by an individual claiming to be an employee of a CBIZ client whose personally identifiable information (“PII”) was compromised and stolen during a cyberattack CBIZ experienced on or about May 31, 2023. As a result of this incident, hackers were able to access and download certain files from CBIZ’s MOVEit Transfer server. The lawsuit alleges that CBIZ and Progress Software Corporation, the owner of MOVEit Transfer, failed to adequately secure and safeguard the individual’s, and similarly situated employees of CBIZ’s clients, PII from unauthorized access. The lawsuit seeks various remedies, including actual, compensatory, and punitive damages, along with injunctive relief, costs, and attorneys’ fees. On December 8, 2023, CBIZ was named as a defendant in a second putative class action lawsuit in the United States District Court for the District of Massachusetts by an individual making similar claims and seeking similar remedies as in the first lawsuit regarding the cyberattack CBIZ experienced on or about May 31, 2023. Both cases were transferred into a multidistrict litigation, styled as In Re: MOVEit Customer Data Security Breach Litigation, pending in the United States District Court for the District of Massachusetts (the “MDL”). To date, the MDL has over 180 cases against over 100 different defendants, all with claims arising out of the cyberbreach by hackers of Progress Software Corporation’s MOVEit Transfer software. The cases in the MDL, including the cases against CBIZ, are in their earliest stages, with a stay in place until the MDL Court issues a scheduling order. Due to the early stage of litigation, the Company is not able to determine or predict the ultimate outcome of these lawsuits nor reasonably provide an estimate or range of the possible outcome or losses, if any. In June of 2025, the Company settled litigation against a small group of former employees. As part of the settlement of that litigation, the Company received a settlement payment of $12.5 million, which was recorded as a pre-tax gain in “Other income, net” on the consolidated statements of comprehensive income for the three and six months ended June 30, 2025. In addition to the items disclosed above, the Company is, from time to time, subject to claims and lawsuits arising in the ordinary course of business. We cannot predict the outcome of all such matters or estimate the possible loss, if any. Although the proceedings are subject to uncertainties in the litigation process and the ultimate disposition of these proceedings is not presently determinable, we intend to vigorously defend these matters. Refer to the Annual Report on Form 10-K for the year ended December 31, 2024 for further discussion on the Company's commitments and contingencies.
