Leases [Abstract]

LEASES

We determine if a contract is a lease at inception. We have leases for office space and facilities, automobiles and certain information technology equipment. All of our leases are classified as operating leases and the majority of which are for office space and facilities.

Supplemental balance sheet information related to the Company’s operating leases as of December 31, 2023 and 2022 was as follows (in thousands):


	December 31, 2023		December 31, 2022
Weighted-average remaining lease term	7.3 years		6.3 years
Weighted-average discount rate	5.51	%	4.14	%

The components of lease cost and other lease information as of and during the year ended December 31, 2023 and 2022 are as follows (in thousands):


	December 31, 2023		December 31, 2022
Operating lease cost	$	45,088	$	43,716
Cash paid for amounts included in measurement of lease liabilities
Operating cash flows for operating leases	$	46,936	$	45,378

Our leases have remaining lease terms ranging from 1 to 20 years. These leases generally contain renewal options for periods ranging from two to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not included in the lease term, and associated potential option payments are excluded from lease payments.

Maturities of operating lease liabilities at December 31, 2023 and minimum cash commitments under operating leases at December 31, 2022 were as follows (in thousands):

Business Combination and Asset Acquisition [Abstract]

Business Combinations

BUSINESS COMBINATIONS

Our acquisition strategy focuses on businesses with a leadership team that is committed to best in class culture, extraordinary client service and cross-serving potential. CBIZ has a long history of acquiring businesses that share common cultural values with us and provide value-added services to the small and midsize business market. The valuation of any business is a subjective process and includes industry, geography, profit margins, expected cash flows, client retention, nature of recurring or non-recurring project-based work, growth rate assumptions and competitive market conditions.

During the year ended December 31, 2023, we completed the following acquisitions:

◦Effective January 1, 2023, we acquired all of the assets of Danenhauer and Danenhauer, Inc. ("Danenhauer and Danenhauer"). Danenhauer and Danenhauer, based in California, is a provider of forensic accounting, business valuation, expert witness testimony, and other services for businesses and individuals. Operating results for Danenhauer and Danenhauer are reported in the Financial Services practice group.

◦Effective February 1, 2023, we acquired the non-attest assets of Somerset CPAs and Advisors ("Somerset"). Somerset, based in Indianapolis, Indiana, is a provider of a full range of accounting, tax, and financial advisory services to clients in a wide array of industries.

Operating results for Ickovic and Co. are reported in the Financial Services practice group.

◦Effective July 1, 2023, we acquired all of the assets of American Pension Advisors, Ltd. ("APA"). APA, based in Indianapolis, Indiana, is a provider of full-service retirement plan consulting and administration assisting more than 1,200 clients in the design, implementation, and administration of all types of retirement plans including 401(k), 403(b), 457(b), defined benefit and cash balance. Operating results for APA are reported in the Benefits and Insurance Services practice group.

During the year ended December 31, 2022, we completed the following acquisitions:

◦Effective January 1, 2022, we acquired all of the non-attest assets of Marks Paneth LLP ("Marks Paneth"). Marks Paneth, based in New York City, is a provider of a full range of accounting, tax and consulting services to a wide range of industries. Marks Paneth is included as a component of our Financial Services practice group. Operating results are reported in the Financial Services practice group.

◦Effective July 1, 2022, we acquired substantially all the assets of Stinnett & Associates, LLC ("Stinnett"). Stinnett, located in Tulsa, Oklahoma, is a professional advisory firm and certified Women's Business Enterprise providing internal audit, Sarbanes-Oxley compliance, cybersecurity reviews, business continuity and disaster recovery, and fraud investigations to businesses of all sizes including Fortune 1000 organizations in a variety of industries. Operating results are reported in the Financial Services practice group.

The acquisitions of Danenhauer and Danenhauer, Somerset, PPS, Ickovic and Co., and APA (together, the "2023 Acquisitions") added approximately $64.9 million in incremental revenue in 2023. During the year ended December 31, 2023, we recorded approximately $3.4 million in non-recurring transaction, retention and integration related costs associated with the Somerset acquisition. During the year ended December 31, 2022, we recorded approximately $10.5 million in non-recurring transaction, retention and integration related costs associated with the Marks Paneth acquisition. Pro forma results of operations for these acquisitions are not provided due to limitations in retrospective application of estimates to historical financial information as well as the immateriality of such information as compared to our total revenue and net income for year ended December 31, 2023 and 2022, respectively.

The following table summarizes the aggregated consideration and purchase price allocation for the acquisitions completed during the year ended December 31, 2023 and 2022, respectively (in thousands):

The following table summarizes the aggregated goodwill and intangible asset amounts resulting from those acquisitions for the twelve months ended December 31, 2023 and 2022, respectively (in thousands):


	Twelve Months Ended December 31,

Other intangibles	18		—		—		—
Total	$	74,536	$	5,985	$	132,547	$	—

Goodwill is calculated as the difference between the aggregated purchase price and the fair value of the net assets acquired. Goodwill represents the value of expected future earnings and cash flows, as well as the synergies created by the integration of the new businesses within our organization, including cross-selling opportunities expected with our Financial Services practice group and the Benefits and Insurance Services practice group, to help strengthen our existing service offerings and expand our market position. Goodwill related to these acquisitions is deductible for tax purposes. Client lists generally have an expected life of 10 years, and other intangibles, primarily non-compete agreements, have an expected life of 3 years. Client lists and non-compete agreements are valued using a discounted cash flow technique based on management estimates of future cash flows from such assets.

The following table summarizes the changes in contingent purchase price consideration for previous acquisitions and contingent payments made for previous business acquisitions during the year ended December 31, 2023 and 2022, respectively (in thousands):

SEC - United States Securities & Exchange Commission.

Organization - CBIZ, Inc. is a leading provider of financial, insurance and advisory services to businesses throughout the United States and parts of Canada. Acting through its subsidiaries, it has been serving small and medium-sized businesses, as well as individuals, governmental entities, and not-for-profit enterprises. CBIZ, Inc. manages and reports its operations along three practice groups: Financial Services, Benefits and Insurance Services and National Practices. A further description of products and services offered by each of the practice groups is provided in Note 19, Segment Disclosures, to the accompanying consolidated financial statements.

Effective April 1, 2023, CBIZ, Inc. formed Rockside Insurance Company, Inc. ("Rockside"), a captive insurance company licensed in Vermont. Rockside, wholly owned by CBIZ, Inc., provides insurance coverages for a portion of the retention deductibles from CBIZ, Inc.'s certain insurance programs with third party insurers.

Basis of Presentation - The accompanying consolidated financial statements reflect the operations of CBIZ, Inc. and all of its wholly-owned subsidiaries (“CBIZ,” the “Company,” “we,” “us” or “our”), after elimination of all intercompany accounts and transactions. We have prepared the accompanying consolidated financial statements in accordance with GAAP and pursuant to the rules and regulations of the SEC.

We have determined that our relationship with certain CPA firms with whom we maintain ASAs qualify as variable interest entities. The accompanying consolidated financial statements do not reflect the operations or accounts of variable interest entities as the impact is not material to our consolidated financial condition, results of operations or cash flows.

Fees earned by us under the ASAs are recorded at net realizable value as a component of “Revenue” in the accompanying Consolidated Statements of Comprehensive Income and were approximately $259.6 million, $235.4 million and $174.8 million for the years ended December 31, 2023, 2022 and 2021, respectively, the majority of which was related to services rendered to privately-held clients. In the event that accounts receivable and unbilled work in process become uncollectible by the CPA firms, the service fee due to us is typically reduced on a proportional basis. Although the ASAs do not constitute control, we are one of the beneficiaries of the agreements and may bear certain economic risks. Refer to Note 17, Related Parties, for further discussion regarding the ASAs.

In 2021, CBIZ formed a grantor trust (the “Trust”) with Wilmington Savings Funds Society, FSB, a Federal savings bank, serving as trustee. The Trust holds the majority of the funds provided by CBIZ’s clients for payroll processing pending remittance to employees of those clients, tax authorities, and other payees. CBIZ is the sole beneficial owner of the Trust. The Trust is considered a variable interest entity in accordance with ASC 810, Consolidation. CBIZ has both the power to direct the activities that most significantly impact the economic performance of the Trust (including the power to make all investment decisions for the Trust) and the right to receive benefits that could potentially be significant to the Trust (in the form of investment returns). As a result, CBIZ consolidates the Trust in its condensed consolidated financial statements.

Certain prior period amounts have been reclassified to conform to current year's presentation.

Significant Accounting Policies - We consider the following policies to be beneficial in understanding the judgments that are involved in the preparation of our consolidated financial statements and the uncertainties that could impact our financial condition, results of operations and cash flows.

Use of Estimates - The preparation of consolidated financial statements in conformity with GAAP and pursuant to the rules and regulations of the SEC requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Management’s estimates and assumptions are derived from and are continually evaluated based upon available information, judgment and experience. Actual results may differ materially from these estimates.

Revenue Recognition - We account for revenue in accordance with Topic 606, Revenue from Contracts with Customers. We recognize revenue based on the five-step model; (i) identify the contract with the customer; (ii) identify the performance obligation in the contract; (iii) determine the contract price; (iv) allocate the transaction price; and (v) recognize revenue as each performance obligation is satisfied. If we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met. For further information on our various streams of revenue, refer to Note 2, Revenue, to the accompanying consolidated financial statements.

Operating Expenses - Operating expenses represent costs of service and other costs incurred to operate our business units and are primarily comprised of personnel costs and occupancy related expenses. Personnel costs include (i) salaries and benefits; (ii) commissions paid to producers; (iii) incentive compensation; and (iv) share-based compensation. Incentive compensation costs and share-based compensation are estimated and accrued. The final determination of incentive compensation is made after year-end results are finalized. The largest components of occupancy costs are rent expense and utilities. Base rent expense is recognized over respective lease terms, while utilities and common area maintenance charges are recognized as incurred.

Share-Based Compensation - The measurement of all share-based compensation arrangements is based on their respective grant date fair value. The grant date fair value of stock options is based on the Black-Scholes-Merton pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate and the expected dividend yield. The grant date fair value of restricted stock awards and restricted stock units is based on the closing price of the underlying stock on the date of issuance. The grant date fair value of the performance share units is based on the closing price of the underlying stock on the date of issuance and recorded based on achievement of target performance metrics. The expense related to stock options, restricted stock awards, and restricted stock units is recognized over the requisite service period which is generally three to four years. The expense related to performance share units is recorded over the three-year performance period based on the fair value on the grant date and adjusted each reporting period for the achievement of the performance metrics, based on our best estimate using available information.

Share-based compensation expense is recorded in the accompanying Consolidated Statements of Comprehensive Income as “Operating expenses” or “Corporate general and administrative expenses,” depending on where the respective individual’s compensation is recorded. For additional discussion regarding share-based awards, refer to Note 14, Employee Share Plans, to the accompanying consolidated financial statements.

Operating Leases - We determine if a contract is a lease at inception. We have leases for office space and facilities, automobiles, and certain information technology equipment. Certain of these leases include options to extend the

lease and some include options to terminate the lease early. As an accounting policy election, we elected not to apply the recognition requirements to short term leases (a lease at commencement date that has a lease term of 12 months or less and does not contain a purchase option that we are reasonably certain to exercise). The ROU assets and lease liabilities are recognized as of the commencement date based on the present value of the lease payments over the lease term. The discount rate utilized for the measurement purpose is based on our secured fixed rate to borrow over a comparable term for the lease because the rate implicit in the lease is not determinable. The lease term may include the options to extend or terminate the lease when it is reasonably certain that we will exercise the applicable option. Related rent expense under such leases is recognized evenly throughout the term of the lease when the total lease commitment is a known amount, and recorded on an as incurred basis when future rent payment increases under the obligation are unknown due to rent escalations being tied to factors that are not currently measurable (such as increases in the consumer price index). Differences between rent expense recognized and the cash payments required under these leases are recorded as a component of “Lease liability” in the current and non-current liabilities sections of the accompanying Consolidated Balance Sheets. We may receive incentives to lease office facilities in certain areas. Such incentives are recorded as a change in lease payments and may require us to remeasure the lease liability to reflect the change in lease payments.

Cash and Cash Equivalents - Cash and cash equivalents consist of cash on hand and investments with an original maturity of three months or less when purchased.

Restricted Cash - Restricted cash consists of funds held by us in relation to our capital and investment advisory services as those funds are restricted in accordance with applicable Financial Industry Regulatory Authority regulations. Restricted cash also consists of funds on deposit from clients in connection with the pass-through of insurance premiums to the carrier with the related liability for these funds recorded in “Accounts payable” in the accompanying Consolidated Balance Sheets.

Accounts Receivable and Allowance for Doubtful Accounts - Accounts receivable, less allowances for doubtful accounts, reflects the net realizable value of receivables and approximates fair value. Unbilled revenues are recorded at estimated net realizable value. Assessing the collectability of receivables (billed and unbilled) requires management judgment based on a combination of factors. When evaluating the adequacy of the allowance for doubtful accounts and the overall probability of collecting on receivables, we analyze historical experience, client credit-worthiness, the age of the trade receivable balances, current economic conditions that may affect a client’s ability to pay and current and projected economic trends and conditions at the balance sheet date. At December 31, 2023 and 2022, the allowance for doubtful accounts was $25.6 million and $20.8 million, respectively, in the accompanying Consolidated Balance Sheets.

Funds Held for Clients and Client Fund Obligations - Services provided by our payroll operations include the preparation of payroll checks, federal, state, and local payroll tax returns, and flexible spending account administration. In relation to these services, as well as other similar service offerings, we collect funds from our clients’ accounts in advance of paying client obligations. These funds, collected before they are due, are segregated and invested in accordance with our investment policy, which requires all investments carry an investment grade rating at the time of initial investment. These investments, primarily consisting of corporate and municipal bonds and U.S. treasury bills, are classified as available-for-sale and are included in the “Funds held for clients” line item on the accompanying Consolidated Balance Sheets. The underlying obligation is recorded as “Client fund obligations” on the Consolidated Balance Sheets. The balances in these accounts fluctuate with the timing of cash receipts and the related cash payments and may vary significantly during the year based on the timing of client’s payroll periods. Other than certain federal and state regulations pertaining to flexible spending account administration, there are no regulatory or other contractual restrictions placed on these funds. Refer to Note 6, Financial Instruments, to the accompanying consolidated financial statements for further discussion of investments related to funds held for clients.

Property and Equipment - Property and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization are provided on a straight-line basis over the following estimated useful lives:


Buildings	25	to	40 years
Furniture and fixtures	5	to	10 years
Capitalized software	3	to	5 years
Equipment	3	to	7 years

Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or the remaining respective lease term. The cost of software purchased or developed for internal use is capitalized and amortized using the straight-line method over an estimated useful life not to exceed five years. We periodically review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. Under those circumstances, if the fair value were less than the carrying amount of the asset, we would recognize a loss for the difference.

Goodwill and Other Intangible Assets - Goodwill represents the excess of the purchase price of the acquired businesses and the related fair value of the net assets acquired. At December 31, 2023, the carrying value of goodwill totaled $865.2 million, compared to total assets of $2.0 billion and total stockholders’ equity of $791.6 million. Intangible assets consist of identifiable intangibles other than goodwill. Identifiable intangible assets other than goodwill include client lists and non-compete agreements which require significant judgments in determining the fair value. We carry client lists and non-compete agreements at cost, less accumulated amortization, in the accompanying Consolidated Balance Sheets.

Goodwill is reviewed for impairment annually during the fourth quarter or more frequently in the event of an impairment indicator. We are required to consider whether it is more likely than not (defined as a likelihood of more than 50%) that the fair value of each reporting unit has fallen below its carrying value, thus requiring us to perform an interim goodwill impairment test. Intangible assets with definite lives, such as client lists and non-compete agreements, are amortized using the straight-line method over their estimated useful lives (generally ranging from three to fifteen years). We review these assets for impairment whenever events or changes in circumstances indicate an asset’s carrying value may not be recoverable. Recoverability is assessed based on a comparison of the undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value determined by a discounted cash flow analysis, market comparable method or a combination thereof as determined to be appropriate in the circumstances.

The goodwill impairment test is performed at a reporting unit level. A reporting unit is an operating segment of a business or one level below an operating segment. At December 31, 2023, we had six reporting units, of which five carry goodwill balances. We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. Under the qualitative assessment, we are not required to calculate the fair value of a reporting unit unless we determine that it is more likely than not that its fair value is less than its carrying amount. If under the quantitative assessment the fair value of a reporting unit is less than its carrying amount, then the amount of the impairment loss, if any, must be measured. Any such impairment charge would reduce earnings and could be material.

After considering changes to assumptions used in our most recent quantitative testing for each reporting unit, including the capital market environment, economic and market conditions, industry competition and trends, our weighted average cost of capital, changes in management and key personnel, the price of our common stock, changes in our results of operations, the magnitude of the excess of fair value over the carrying amount of each reporting unit as determined in our most recent quantitative testing, and other factors, we concluded that it was more likely than not that the fair values of each of our reporting units exceeded their respective carrying values and, therefore, did not perform a quantitative impairment analysis. For further information regarding our goodwill balances, refer to Note 5, Goodwill and Other Intangible Assets, net, to the accompanying consolidated financial statements.

Income Taxes - Income taxes are provided for the tax effects of transactions reported in the consolidated financial statements and consist of taxes currently payable and deferred taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and operating losses and tax credit carryforwards. State income tax credits are accounted for using the flow-through method.

A valuation allowance is provided when it is more-likely-than-not that all or some portion of a deferred tax asset will not be realized. We determine valuation allowances based on all available evidence. Such evidence includes historical results, the reversal of deferred tax liabilities, expectations of future consolidated and/or separate company profitability and the feasibility of tax-planning strategies. Determining valuation allowances includes significant judgment by management, and different judgments could yield different results.

Accounting for uncertain tax positions requires a more-likely-than-not threshold for recognition in the consolidated financial statements. We recognize a tax benefit based on whether it is more-likely-than-not that a tax position will be sustained. We record a liability to the extent that a tax position taken or expected to be taken on a tax return exceeds the amount recognized in the consolidated financial statements.

Business Combinations - We recognize and measure identifiable tangible and intangible assets acquired and liabilities assumed as of the acquisition date at fair value. Fair value measurements require extensive use of estimates and assumptions, including estimates of future cash flows to be generated by the acquired assets. The operating results of acquired businesses are included in our consolidated financial statements beginning on the date of acquisition. The purchase price is equivalent to the fair value of consideration transferred. Goodwill is recognized for the excess of purchase price over the net fair value of assets acquired and liabilities assumed.

Contingent Purchase Price Liabilities - Contingent purchase price liabilities consisting of cash payments and common stock issuances result from our business acquisitions and are recorded at fair value at the time of acquisition as “Contingent purchase price liability - current” and “Contingent purchase price liability - non-current” in the accompanying Consolidated Balance Sheets. We estimate the fair value of our contingent purchase price liabilities using a probability-weighted discounted cash flow model. We probability weight risk-adjusted estimates of future performance of acquired businesses, then calculate the contingent purchase price based on the estimates and discount them to present value representing management’s best estimate of fair value. The fair value of the contingent purchase price liabilities, which is considered a Level 3 unobservable input, is reassessed on a quarterly basis based on assumptions provided by practice group leaders and business unit controllers together with our corporate finance department. Any change in the fair value estimate, including the revaluation of common stock, is recorded in the earnings of that period. For the years ended December 31, 2023, 2022 and 2021, we recorded other expense of $2.7 million, $2.4 million and $2.4 million, respectively, related to net changes in the fair value of contingent consideration.

Refer to Note 7, Fair Value Measurements, and Note 18, Business Combinations, for further discussion of our contingent purchase price liabilities and acquisitions.

Interest Rate Derivative Instruments - We maintain interest rate swaps that are designated as cash flow hedges to manage the market risk from changes in interest rates on our floating-rate debt under our $600.0 million unsecured credit facility, by and among CBIZ Operations, Inc., CBIZ, Inc. and Bank of America, N.A., as administrative agent and bank, and other participating banks. The designation of a derivative instrument as a hedge and its ability to meet the hedge accounting criteria determine how we reflect the change in fair value of the derivative instrument. A derivative qualifies for hedge accounting treatment if, at inception, it meets defined correlation and effectiveness criteria. These criteria require that the anticipated cash flows and/or changes in fair value of the hedging instrument substantially offset those of the position being hedged.

We utilize derivative instruments to manage interest rate risk associated with our floating-rate debt under the credit facility. Interest rate swap contracts mitigate the risk associated with the underlying hedged item. If the contract is designated as a cash flow hedge, the mark-to-market gains or losses on the swap are deferred and included as a component of accumulated other comprehensive income, net of tax, to the extent effective, and reclassified to interest expense in the same period during which the hedged transaction affects earnings. For further discussion regarding derivative financial instruments, refer to Note 6, Financial Instruments, to the accompanying consolidated financial statements.

Recent Accounting Pronouncements - The FASB ASC is the sole source of authoritative GAAP other than the SEC issued rules and regulations that apply only to SEC registrants. The FASB issues an ASU to communicate changes to the FASB codification. We assess and review the impact of all ASUs. ASUs not listed below were

reviewed and determined to be either not applicable or are not expected to have a material impact on the consolidated financial statements.

Accounting Standards Adopted in 2023

In August 2023, the FASB issued ASU No. 2023-04, Liabilities (Topic 405): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 121, which amended and added various SEC paragraphs in the ASC to reflect the issuance of SEC Staff Bulletin No. 121. We adopted ASU No. 2023-04 upon issuance and the adoption did not have a material impact on our consolidated financial statements and related disclosures.

In July 2023, the FASB issued ASU No. 2023-03, Presentation of Financial Statements (Topic 205), Income Statement - Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation - Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock, which amended and added various SEC paragraphs in the ASC to reflect the issuance of SEC Staff Bulletin No. 120. We adopted ASU No. 2023-03 upon issuance and the adoption did not have a material impact on our consolidated financial statements and related disclosures.

Accounting Standards Issued But Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about an entity's effective tax rate reconciliation as well as information on income tax paid. The guidance in this ASU is effective for public companies with annual periods beginning after December 15, 2024. We plan to adopt the guidance for the fiscal year ending December 31, 2025. We are currently evaluating the effect adoption of this ASU will have on our consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves reportable segment disclosure requirements, primarily through enhanced disclosure about significant segment expenses. The guidance in this ASU is effective for public companies with annual periods beginning after December 15, 2023, and interim periods within the annual period beginning after December 15, 2024. We plan to adopt the guidance for the fiscal year ending December 31, 2024. We are currently evaluating the effect adoption of this ASU will have on our consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The inputs used to measure fair value are classified into the following hierarchy:

•Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities

•Level 2 — Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability

•Level 3 — Unobservable inputs for the asset or liability

We endeavor to utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. As circumstances change, we will reassess the level in which the inputs are included in the fair value hierarchy.

For the years ended December 31, 2023 and 2022, there were no transfers between the valuation hierarchy Levels 1, 2 and 3. The following table summarizes our assets and (liabilities) at December 31, 2023 and 2022 that are measured at fair value on a recurring basis subsequent to initial recognition and indicates the fair value hierarchy of the valuation techniques utilized by us to determine such fair value (in thousands):


	Level	December 31, 2023	December 31, 2022
Deferred compensation plan assets	1	143,499	118,862
Available-for-sale debt securities	1	39,459	43,485
Other depository assets	1	1,031	868
Deferred compensation plan liabilities	1	(143,499)	(118,862)
Interest rate swaps, net	2	3,999	7,809
Bank debt	2	(310,826)	(263,654)
Contingent purchase price liabilities	3	(114,946)	(132,010)

Contingent Purchase Price Liabilities - During the years ended December 31, 2023 and 2022, we recorded expense of $2.7 million and expense of $2.4 million, respectively, due to accretion, adjusting for expected results of acquired businesses and the revaluation of stock related to contingent payments. These changes are included in Other income (expense), net in the accompanying Consolidated Statements of Comprehensive Income. Refer to Note 18, Business Combinations, for further discussion of our acquisitions and contingent purchase price liabilities.

The following table summarizes the change in fair value of our contingent purchase price liabilities identified as Level 3 for the years ended December 31, 2023 and 2022 (pre-tax basis, in thousands):

Segment Reporting [Abstract]

Segment Disclosures

SEGMENT DISCLOSURES

Our business units have been aggregated into three practice groups: (i) Financial Services, (ii) Benefits and Insurance Services and (iii) National Practices, based on the following factors: similarity of the products and services provided to clients, similarity of the regulatory environment in which they operate; and similarity of economic conditions affecting long-term performance. The business units are managed along these segment lines. A general description of services provided by practice groups is provided in the table below.

Financial Services

Benefits and Insurance Services

National Practices

Accounting and Tax

Employee Benefits Consulting

Information Technology Managed Networking and Hardware Services

Financial Advisory

Payroll / Human Capital Management

Healthcare Consulting

Valuation

Property and Casualty Insurance

Risk and Advisory Services

Retirement and Investment Services

Government Health Care Consulting

Corporate and Other - Included in Corporate and Other are operating expenses that are not directly allocated to the individual business units. These expenses primarily consist of certain healthcare costs, gains or losses attributable to assets held in our non-qualified deferred compensation plan, stock-based compensation, consolidation and integration charges, certain professional fees, certain advertising costs and other various expenses.

The discrete financial information of those practice groups are available and regularly reviewed by the Chief Operating Decision Maker ("CODM"). The CODM, who is our CEO, allocates resources to and assesses the performance of each practice group using information about their respective revenue and income (loss) before income tax expense (benefit), excluding those costs listed above, which are reported in the “Corporate and Other”. Upon consolidation, intercompany accounts and transactions are eliminated, thus inter-segment revenue is not included in the measure of profit or loss for the practice groups. The CODM does not evaluate practice groups using discrete asset information, and we do not identify or allocate assets by practice groups.

We operate in the United States and Canada and revenue generated from such operations during the years ended December 31, 2023, 2022 and 2021 was as follows (in thousands):

EARNINGS PER SHARE

The following table sets forth the reconciliation of the numerator and the denominator of basic earnings per share and diluted earnings per share for the years ended December 31, 2023, 2022 and 2021 (in thousands, except per share data):

Diluted earnings per share	$	2.39	$	2.01	$	1.32

(1)For the years ended December 31, 2023, 2022 and 2021, a total of 58 thousand, 68 thousand and 23 thousand stock based awards, respectively, were excluded from the calculation of diluted earnings per share as their exercise prices would render them anti-dilutive.

(2)Contingent shares represent additional shares to be issued for purchase price earned by former owners of businesses acquired by us once future conditions have been met. For further details, refer to Note 18, Business Combinations.

(3)The denominator used in calculating diluted earnings per share did not include 0.2 million, 0.2 million and 0.3 million performance share units for the twelve months ended December 31, 2023, 2022 and 2021 respectively. The performance conditions associated with these performance share units were not met and consequently none of these performance share units were considered as issuable for the years ended December 31, 2023, 2022 and 2021.

The tax effects of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2023 and 2022, were as follows (in thousands):


	2023		2022

Total gross deferred tax liabilities	80,380		72,282
Deferred income taxes, net	$	(29,287)	$	(24,763)

We have established valuation allowances for deferred tax assets related to certain employee benefits and compensation and state net operating loss (“NOL”) carryforwards at December 31, 2023 and December 31, 2022.

The net decrease in the valuation allowance of $0.4 million for the year ended December 31, 2023 related to changes in the valuation allowance for NOLs and certain employee benefits and compensation.

In assessing the realization of deferred tax assets, management considers all available positive and negative evidence, including projected future taxable income, scheduled reversal of deferred tax liabilities, historical financial operations and tax planning strategies. Based upon review of these items, management believes it is more-likely-than-not that the Company will realize the benefits of these deferred tax assets, net of the existing valuation allowances.

We file income tax returns in the United States, Canada, and most state jurisdictions. CBIZ's federal income tax returns for years ending prior to January 1, 2020 are no longer subject to examination. With limited exceptions, our state and local income tax returns and non-U.S. income tax returns are no longer subject to tax authority examinations for years ending prior to January 1, 2019 and January 1, 2018, respectively.

The availability of NOLs and state tax credits are reported as a component of deferred tax assets, net of applicable valuation allowances, in the accompanying Consolidated Balance Sheets. At December 31, 2023, we had state net operating loss carryforwards of $50.8 million and a state tax credit carryforward of $0.1 million. The state net operating loss carryforwards expire on various dates between 2025 and 2044 and the state tax credit carryforward expires in 2028.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

Included in the balance of unrecognized tax benefits at December 31, 2023 are $1.1 million of unrecognized tax benefits that, if recognized, would affect the effective tax rate. We believe it is reasonably possible that certain of these unrecognized tax benefits could change in the next twelve months. We expect reductions in the liability for unrecognized tax benefits of approximately $0.2 million within the next twelve months due to expiration of statutes of limitation. Given the number of years that are currently subject to examination, we are unable to estimate the range of potential adjustments to the remaining balance of unrecognized tax benefits at this time.

We recognize interest expense and penalties related to unrecognized tax benefits as a component of income tax expense. During 2023, we recorded an immaterial increase in accrued interest, and, as of December 31, 2023, we had recognized a liability for interest expense and penalties of $0.3 million and $0.2 million, respectively, relating to unrecognized tax benefits. During 2022, we recorded an immaterial increase in accrued interest, and, as of December 31, 2022, we had recognized a liability for interest expense and penalties of $0.3 million and $0.2 million, respectively, relating to unrecognized tax benefits.

Equity [Abstract]
Common Stock	COMMON STOCK Share Repurchase Program - Our Board of Directors approved various share repurchase programs that were effective during the years ended December 31, 2023 and 2022. Under these programs, shares may be purchased in the open market or in privately negotiated transactions according to SEC rules. The Share Repurchase Program does not obligate us to acquire any specific number of shares and may be suspended at any time. Repurchased shares are held in treasury and may be reserved for future use in connection with acquisitions, employee share plans and other general purposes. Under the 2022 credit facility, described in Note 9, Debt and Financing Arrangements, share repurchases are unlimited when total leverage is less than 3.0. When leverage is greater than 3.0, the annual share repurchase is limited to $35.0 million. Under the Share Repurchase Program, we repurchased 1.3 million and 2.8 million shares on the open market at a cost (including fees and commissions) of $65.1 million and $122.8 million during the years ended December 31, 2023 and 2022, respectively. Shares repurchased to settle statutory employee withholding related to vesting of stock awards were 0.2 million shares at a cost of $8.4 million during the year ended December 31, 2023 and 0.2 million shares at a cost of $7.3 million during the year ended December 31, 2022.

Debt and Financing Arrangements

DEBT AND FINANCING ARRANGEMENTS

2022 credit facility

On May 4, 2022, we entered into a credit facility (the "2022 credit facility" or the "credit facility"), which amended and restated the 2018 credit facility. The 2022 credit facility increased our borrowing capacity from $400 million to $600 million, providing us with the capital necessary to meet our working capital needs as well as the flexibility to continue with our strategic initiatives, including business acquisitions and share repurchases. Other important key terms of the 2022 credit facility included: (i) an accordion feature that permits lenders to extend an additional $200 million at later date; (ii) no change in pricing from the 2018 credit facility; (iii) upsizing of baskets and various sublimits to reflect the increased size of the Company's business; (iv) a swing line facility increase from $25 million to

$50 million, providing for same-day funds to cover daily liquidity needs; and (v) base interest rate amended from LIBOR to Term SOFR.

In connection with our 2022 credit facility, we incurred approximately $2.1 million of financing costs during the second quarter of 2022. The financing costs are deferred and reported as a reduction of debt on the accompanying Consolidated Balance Sheets, are included as a component of cash flow from financing activities on the accompanying Consolidated Statements of Cash Flows, and are being amortized as interest expense over the term of the 2022 credit facility. In addition, we wrote-off approximately $41 thousand of unamortized deferred cost associated with the 2018 credit facility as additional interest expense in the second quarter of 2022.

The 2022 credit facility matures on May 4, 2027. The balance outstanding under the 2022 credit facility was $312.4 million and $265.7 million for the year ended December 31, 2023 and 2022, respectively. The combined effective interest rates under the 2018 and 2022 credit facilities, including the impact of interest rate swaps associated with those credit facilities, were as follows:


	2023	2022
Weighted average rates	5.23%	2.67%
Range of effective rates	1.93% - 8.00%	1.08% - 5.44%

We had approximately $272.0 million of available funds under the 2022 credit facility at December 31, 2023, based on the terms of the commitment. Available funds under the credit facility are based on a multiple of earnings before interest, taxes, depreciation and amortization as defined in the credit facility, and are reduced by letters of credit, other indebtedness and outstanding borrowings under the credit facility. Under the 2022 credit facility, loans are charged an interest rate consisting of a base rate or term SOFR rate plus an applicable margin, letters of credit are charged based on the same applicable margin, and a commitment fee is charged on the unused portion of the credit facility.

The 2022 credit facility contains certain restrictive covenants customary for facilities of this type, including restrictions on indebtedness, liens or other encumbrances, making certain payments, investments, or to sell or otherwise dispose of a substantial portion of assets, or to merge or consolidate with an unaffiliated entity. The 2022 credit facility also limits our ability to make dividend payments. Historically, we have not paid cash dividends on our common stock. Our Board of Directors has discretion over the payment and level of dividends on common stock, subject to the limitations of the credit facility and applicable law. The credit facility contains a provision that, in the event of a defined change in control, the credit facility may be terminated. In addition, the 2022 credit facility contains financial covenants that require us to meet certain requirements with respect to (i) a total leverage ratio and (ii) minimum interest charge coverage ratio which may limit our ability to borrow up to the total commitment amount. As of December 31, 2023, we are in compliance with all covenants.

Other line of credit

We have an unsecured $20.0 million line of credit by and among CBIZ Benefits and Insurance, Inc., our wholly owned subsidiary, and the Huntington Bank. We utilize this line of credit to support our short-term funding requirements of payroll client fund obligations due to the investment of client funds, rather than liquidating client funds that have already been invested in available-for-sale securities. Refer to Note 6, Financial Instruments, for further discussion regarding these investments. The line of credit, which was renewed on August 3, 2023 and will terminate on August 1, 2024, did not have a balance outstanding at December 31, 2023 and 2022. Borrowings under the line of credit bear interest at the prime rate.

Interest expense

Interest expense, including amortization of deferred financing costs, commitment fees, line of credit fees, and other applicable bank charges, was as follows (in thousands):


	2023		2022		2021
Credit facilities	$	20,093	$	8,033	$	3,843

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Financial Instruments

FINANCIAL INSTRUMENTS

The carrying amounts of our cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturity of these instruments and are classified as Level 1 in the fair value hierarchy. The carrying value of bank debt approximates fair value, as the interest rate on the bank debt is variable and approximates current market rates. As a result, the fair value measurement of our bank debt is classified as Level 2 in the fair value hierarchy.

Concentrations of Credit Risk - Financial instruments that may subject us to concentration of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and cash equivalents with highly-rated financial institutions, limiting the amount of credit exposure with any one financial institution. Our client base consists of large numbers of geographically diverse customers dispersed throughout the United States; thus, concentration of credit risk with respect to accounts receivable is not significant.

Available-For-Sale Debt Securities - Available-for-sale debt securities consist primarily of corporate and municipal bonds. The net par values of these securities total $40.0 million and $44.4 million at December 31, 2023 and 2022, respectively. The bonds have maturity dates or callable dates ranging from January 2024 through December 2025, and are included in “Funds held for clients — current” in the accompanying Consolidated Balance Sheets based on our intent and ability to sell these investments at any time under favorable conditions.

At December 31, 2023 and December 31, 2022, unrealized losses on the securities were not material and have not been recognized as a credit loss because the bonds are investment grade quality and management is not required or does not intend to sell prior to an expected recovery in value. The bond issuers continue to make timely principal and interest payments.

The following table summarizes our bond activity for the years ended December 31, 2023 and 2022 (in thousands):


	2023		2022
Fair value at January 1	$	43,485	$	38,670
Purchases	14,122		19,771
Redemptions	(3,310)		(5,630)
Maturities	(15,155)		(6,770)
Change in bond premium	(1,099)		(645)
Fair market value adjustment	1,416		(1,911)
Fair value at December 31	$	39,459	$	43,485

In addition to the available-for-sale securities discussed above, we also held other depository assets in the amount of $1.0 million and $0.9 million at December 31, 2023 and December 31, 2022, respectively. Those depository assets are classified as Level 1 in the fair value hierarchy.

Interest Rate Swaps - We utilize interest rate swaps to manage interest rate risk exposure associated with our floating-rate debt under the 2022 credit facility, or the forecasted acquisition of such liability. To mitigate counterparty credit risk, we only enter into contracts with selected major financial institutions with investment grade ratings and continually assess their creditworthiness. There are no credit risk-related contingent features in our interest rate swaps nor do the swaps contain provisions under which we would be required to post collateral. We do not purchase or hold any derivative instruments for trading or speculative purposes.

The designation of a derivative instrument as a hedge and its ability to meet the hedge accounting criteria determine how we reflect the change in fair value of the derivative instrument. A derivative qualifies for hedge accounting treatment if, at inception, it meets defined correlation and effectiveness criteria. These criteria require that the anticipated cash flows and/or changes in fair value of the hedging instrument substantially offset those of the position being hedged.

We had no fair value hedging instruments at December 31, 2023 or 2022. Our interest rate swaps are designated as cash flow hedges. Accordingly, the interest rate swaps are recorded as either an asset or liability in the accompanying Consolidated Balance Sheets at fair value. The mark-to-market gains or losses on the swaps are deferred and included as a component of accumulated other comprehensive income (“AOCI”), net of tax, to the extent the hedge is determined to be effective, and reclassified to interest expense in the same period during which the hedged transaction affects earnings. The interest rate swaps are assessed for effectiveness and continued qualification for hedge accounting on a quarterly basis. For the years ended December 31, 2023 and 2022, the interest rate swaps were deemed to be effective.

As a result of the 2022 credit facility, CBIZ amended the interest rate swap agreements with respect to the existing swaps. Effective May 16, 2022, the scheduled reset date, the interest rate of the swaps are set to one-month term SOFR to align the swaps to term SOFR in the 2022 credit facility as a result of reference rate reform. No other terms under the swap agreements were amended.

As of December 31, 2023, we have five interest rate swaps outstanding. Under the terms of the interest rate swaps, we pay interest at a fixed rate of interest plus applicable margin as stated in the amended agreements, and receive interest that varies with the one-month term SOFR. The following table summarizes our outstanding interest rate swaps and their classification in the accompanying Consolidated Balance Sheets at December 31, 2023 and 2022 (in thousands). Refer to Note 7, Fair Value Measurements, to the accompanying consolidated financial statements for additional disclosures regarding fair value measurements.

During the next twelve months, the amount of the December 31, 2023 AOCI balance that will be reclassified to earnings is expected to be immaterial.

Retirement Benefits [Abstract]
Employee Benefits	EMPLOYEE BENEFITS Employee Savings Plan - We sponsor a qualified 401(k) defined contribution plan that covers substantially all of our employees. Participating employees may elect to contribute, on a tax-deferred basis, up to 80% of their pre-tax annual compensation (subject to a maximum permissible contribution under Section 401(k) of the Internal Revenue Code). Matching contributions by us are 50% of the first 6% of base compensation that the participant contributes, and additional amounts may be contributed at the discretion of the Board of Directors. Participants may elect to invest their contributions in various funds including: equity, fixed income, stable value, and balanced-lifecycle funds. Employer contributions (net of forfeitures) made to the plan during the years ended December 31, 2023, 2022 and 2021 were approximately $18.5 million, $16.1 million and $13.2 million, respectively. Non-qualified Deferred Compensation Plan - We sponsor a non-qualified deferred compensation plan, under which certain members of management and other highly compensated employees may elect to defer receipt of a portion of their annual compensation, subject to maximum and minimum percentage limitations. The amount of compensation deferred under the plan is credited to each participant’s deferral account and a non-qualified deferred compensation plan obligation is established by us. An amount equal to each participant’s compensation deferral is transferred into a rabbi trust and invested in various debt and equity securities as directed by the participants. The assets of the rabbi trust are held by us and recorded as “Assets of deferred compensation plan” in the accompanying Consolidated Balance Sheets. Assets of the non-qualified deferred compensation plan consist primarily of investments in mutual funds, money market funds and equity securities. The values of these investments are based on published market prices at the end of the period. Adjustments to the fair value of these investments are recorded in “Other (expense) income, net,” offset by the same adjustments to compensation expense (recorded as “Operating expenses” or “G&A expenses” in the accompanying Consolidated Statements of Comprehensive Income). We recorded income of $19.5 million related to those investments for the year ended December 31, 2023. For the year ended December 31, 2022, we recorded a loss of $19.6 million and income of $19.5 million for the year ended December 31, 2021, related to these investments. These investments are specifically designated as available to us solely for the purpose of paying benefits under the non-qualified deferred compensation plan. However, the investments in the rabbi trusts would be available to all unsecured general creditors in the event that we become insolvent. Deferred compensation plan obligations represent amounts due to plan participants and consist of accumulated participant deferrals and changes in fair value of investments thereon since the inception of the plan, net of withdrawals. This liability is an unsecured general obligation of ours and is recorded as “Deferred compensation plan obligations” in the accompanying Consolidated Balance Sheets. The assets and liabilities related to the non-qualified deferred compensation plan at December 31, 2023 and 2022 were $143.5 million and $118.9 million, respectively.

Employee Stock Plans

Share-Based Payment Arrangement [Abstract]

Employee Stock Plans

EMPLOYEE STOCK PLANS

Employee Stock Purchase Plan - The 2007 Employee Stock Purchase Plan (“ESPP”), which has a termination date of June 30, 2024, allows qualified employees to purchase shares of common stock through payroll deductions up to a limit of $25,000 of stock per calendar year. The price an employee pays for shares is 85% of the fair market value of our common stock on the last day of the purchase period. Purchase periods begin on the sixteenth day of the month and end on the fifteenth day of the subsequent month. Other than a one-year holding period from the date of purchase, there are no vesting or other restrictions on the stock purchased by employees under the ESPP. The total number of shares of common stock that can be purchased under the ESPP shall not exceed 2.0 million shares.

Stock Awards - We granted various stock-based awards through the year ended December 31, 2023 under the CBIZ, Inc. 2019 Stock Omnibus Incentive Plan (“2019 Plan”). On May 10, 2023, the stockholders of the Company approved an amendment to the 2019 Plan. The amendment added 1.5 million shares to the total number of shares that may be issued under the 2019 Plan. The 2019 Plan, which expires in 2029, permits the grant of various forms of stock-based awards. The terms and vesting schedules for the share-based awards vary by type and date of grant. Under the 2019 Plan, a maximum of 4.6 million stock options, restricted stock or other stock based compensation awards may be granted. Shares subject to award under the 2019 Plan may be either authorized but unissued shares of our common stock or treasury shares. At December 31, 2023, approximately 2.9 million shares were available for future grant under the 2019 Plan.

Effective January 1, 2020, the 2019 Plan replaced and superseded the CBIZ, Inc. 2014 Stock Incentive Plan (“2014 Plan”). The terms and vesting schedule for the stock-based awards vary by type and date of grant.

During the years ended December 31, 2023, 2022 and 2021, we recognized compensation expense (before income tax expense) for these awards as follows (in thousands):


	2023		2022		2021
Stock options	$	768	$	248	$	1,291
Restricted stock units and awards	5,258		5,204		5,603
Performance share units	6,260		9,237		4,513
Total share-based compensation expense	$	12,286	$	14,689	$	11,407

Stock Options - Certain employees and non-employee directors were granted stock options. Stock options awarded to non-employee directors have generally been granted with immediate vesting. Stock options awarded to employees are generally subject to a 25% incremental vesting schedule over a four-year period commencing from the date of grant. At the discretion of the Compensation Committee of the Board of Directors, options awarded under the 2019 Plan may vest in a time period shorter than four years. Stock options expire six years from the date of grant and are awarded with an exercise price equal to the market value of our common stock on the date of grant. Stock options may be granted alone or in addition to other awards and may be of two types: incentive stock options and non-qualified stock options. During the year ended December 31, 2023 and 2021, we granted 50 thousand and 50 thousand stock options to non-employee directors, respectively. We did not grant any stock options during the year ended December 31, 2022.

Stock option activity during the year ended December 31, 2023 was as follows (number of options in thousands):


	Number of Options	Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value (in millions)
Outstanding at December 31, 2022	553	$	21.03
Granted	50	$	48.40
Exercised	(453)	$	19.35

Outstanding at December 31, 2023	150	$	35.22	3.77 years	$	4.1
Vested and exercisable at December 31, 2023	150	$	35.22	3.77 years	$	4.1

•The weighted-average grant-date fair value of stock options granted during the years ended December 31, 2023 and 2021 was $0.8 million and $0.4 million, respectively.

•The aggregate intrinsic value of stock options exercised during each of the years ended December 31, 2023, 2022 and 2021 was $15.0 million, $19.1 million and $13.6 million, respectively. The intrinsic value is calculated as the difference between our stock price on the exercise date and the exercise price of each option exercised.

•At December 31, 2023, we didn't have any unrecognized compensation cost for stock options.

We utilized the Black-Scholes-Merton option-pricing model to determine the fair value of stock options on the date of grant. The fair value of stock options granted during the years ended December 31, 2023 and 2021 were $15.35 and $8.10, respectively. The following weighted average assumptions were utilized:


	2023		2021
Expected volatility (1)	28.57	%	27.49	%
Expected option life (years) (2)	4.74		4.71
Risk-free interest rate (3)	3.89	%	0.74	%
Expected dividend yield (4)	—	%	—	%

(1)The expected volatility assumption was determined based upon the historical volatility of our stock price, using daily price intervals.

(2)The expected option life was determined based upon our historical data using a midpoint scenario, which assumes all options are exercised halfway between the expiration date and the weighted average time it takes the option to vest.

(3)The risk-free interest rate assumption was upon zero-coupon U.S. Treasury bonds with a term approximating the expected life of the respective options.

(4)The expected dividend yield assumption was determined in view of our historical and estimated dividend payouts.

Restricted Stock Units and Awards - Under the 2019 Plan, certain employees and non-employee directors were granted restricted stock units and awards. Restricted stock units and awards are independent of option grants and vest at no cost to the recipients. Restricted stock units and awards are subject to forfeiture if employment terminates prior to the release of restrictions, generally one to four years from the date of grant. Recipients of restricted stock units and awards are entitled to the same dividend and voting rights as holders of other CBIZ common stock, subject to certain restrictions during the vesting period, and these are considered to be issued and outstanding from the date of grant. Shares granted under the 2019 Plan cannot be sold, pledged, transferred or assigned during the vesting period.

Restricted stock units and awards activity during the year ended December 31, 2023 was as follows (in thousands, except per share data):


	Number of Shares	Weighted Average Grant-Date Fair Value (1)
Non-vested at December 31, 2022	277	$	32.62
Granted	109	$	48.64
Vested	(163)	$	31.63

Non-vested at December 31, 2023	223	$	41.19

(1)Represents weighted average market value of the shares as the awards are granted at no cost to the recipients.

•At December 31, 2023, we had unrecognized compensation cost for restricted stock units and awards of $5.2 million to be recognized over a weighted average period of approximately 0.72 years.

•The total fair value of shares vested during the years ended December 31, 2023, 2022 and 2021 was approximately $5.1 million, $5.6 million and $4.9 million, respectively.

•The market value of shares awarded during the years ended December 31, 2023, 2022 and 2021 was $5.3 million, $5.0 million and $5.0 million, respectively. This market value was recorded as unearned compensation and is recognized as expense ratably over the periods which the restrictions lapse.

•Awards outstanding at December 31, 2023 will be released from restrictions at dates ranging from February, 2024 through February, 2026.

Performance Share Units (“PSUs”) - PSUs are earned based on our financial performance over a contractual term of three years and the associated expense is recognized over that period based on the fair value of the award. A three-year cliff vesting schedule of the PSUs is dependent upon the Company’s performance relative to pre-established goals based on earnings per share target (weighted 70%) and total growth in revenue (weighted 30%). The fair value of PSUs is calculated using the market value of our common stock on the date of grant. For performance achieved above specified levels, the recipient may earn additional shares of stock, not to exceed 200% of the number of PSUs initially granted.

The following table presents our PSUs award activity during the twelve months ended December 31, 2023 (in thousands, except per share data):


	Performance Share Units	Weighted Average Grant-Date Fair Value Per Unit (1)
Outstanding at December 31, 2022	482	$	28.84
Granted	88	$	48.40
Vested	(244)	$	25.75

Financial Services

Revenue primarily consists of professional service fees derived from traditional accounting services, tax return preparation, administrative services, financial and risk advisory, consulting and valuation services. Clients are billed for these services based upon a fixed-fee, an hourly rate, or an outcome-based fee. Time related to the performance of all services is maintained in a time and billing system.

Revenue for fixed-fee arrangements is recognized over time with the performance obligation measured in hours worked and anticipated realization. Anticipated realization is defined as the fixed fee divided by the product of the hours anticipated to complete a performance obligation and the standard billing rate. Anticipated realization rates are applied to hours charged to a contract when recognizing revenue. At the end of each reporting period, we evaluate the work performed to date to ensure that the amount of revenue recognized in each reporting period for the client arrangement is equal to the performance obligations met.

Time and expense arrangement revenue is recognized over time with progress measured towards completion with value being transferred through our hourly fee arrangement at expected net realizable rates per hour, plus agreed-upon out-of-pocket expenses. The cumulative impact on any subsequent revision in the estimated realizable value of unbilled fees for a particular client project is reflected in the period in which the change becomes known.

Prior to recognizing revenue for outcome-based arrangement, we estimate the transaction price, including variable consideration that is subject to a constraint based on risks specific to the arrangement. We evaluate the estimate in each reporting period and recognize revenue to the extent it is probable that a significant reversal of revenue will not occur. Revenue is recognized when the constraint is lifted at a point in time when the value is determined and verified by a third party.

Benefits and Insurance Services

Benefits and Insurance Services provides brokerage and consulting along lines of service which include group health benefits consulting and brokerage, property and casualty brokerage, retirement plan advisory, payroll, human capital management, actuarial, life insurance and other related services. Revenue consists primarily of fee income for administering health and retirement plans and brokerage commissions. Revenue also includes investment income related to client payroll funds that are held in CBIZ accounts, as is industry practice. We pay commissions monthly and require the recipient of the commission to be employed as of the end of the month in which the commissions are earned (as opposed to at the time of actual payment). Failure to remain employed at the date the

commission is payable results in the forfeiture of commissions that would otherwise be due. Therefore, we have determined that the requirement of continued employment is substantive and accordingly, do not consider the commissions to be incremental costs of obtaining the customer contract and consequently a contract acquisition cost is not recognized for those commissions.

Revenue related to group health benefits consulting consists of (i) commissions, (ii) fee income which can be fixed or variable based on a price per participant and (iii) contingent revenue.

•Commission revenue and fee income are recognized over the contract period as these services are provided to clients continuously throughout the term of the arrangement. Our customers benefit from each month of service on its own and although volume and the number of participants may differ month to month, our obligation to perform substantially remains the same.

•Contingent revenue arrangements are related to carrier-based performance targets. Due to the uncertainty of the outcome and the probability that a change in estimate would result in a significant reversal of revenue, we have applied a constraint on recording contingent revenue. Revenue is recognized when the constraint has been lifted which is the earlier of written notification from a carrier that the target has been achieved or cash collection. Contingent revenue is not a significant revenue stream to our consolidated financial position or results of operations.

Revenue related to property and casualty consists of (i) commissions and (ii) contingent revenue.

•Commissions relating to agency billing arrangements (pursuant to which we bill the insured, collect the funds and forward the premium to the insurance carrier less our commission) and direct billing arrangements (pursuant to which the insurance carrier bills the insured directly and forwards the commission to us) are both recognized on the effective date of the policy. Commission revenue is reported net of reserves for estimated policy cancellations and terminations. The cancellation and termination reserve is based upon estimates and assumptions using historical cancellation and termination experience and other current factors to project future experience.

•Contingent revenue arrangements related to carrier-based performance targets include claim loss experience and other factors. Due to the uncertainty of the outcome and the probability that a change in estimate would result in a significant reversal of revenue, we have applied a constraint on recording contingent revenue. Revenue is recognized when the constraint has been lifted which is the earlier of written notification from a carrier that the target has been achieved or cash collection. Contingent revenue is not a significant revenue stream to our consolidated financial position or results of operations.

Revenue related to retirement plan services consist of advisory, third party administration and actuarial services.

•Advisory revenue is either (i) based on the value of assets under management, as provided by a third party, multiplied by an agreed upon rate, (ii) fee based, or (iii) a combination of fixed fee and value of assets under management. Advisory services revenue, derived from the value of assets under management, is calculated monthly or quarterly based on the estimated value of assets under management, as it is earned over the duration of the reporting period and relates to performance obligations satisfied during that period. The variability related to the estimated asset values used to recognize revenue during the reporting period is resolved and the amount of related revenue recognized is adjusted when the actual value of assets under management is known. Fee based Advisory revenue is recognized over the contract period as these services are provided to clients continuously throughout the term of the arrangement. Our clients benefit from each month of service on its own, and although the volume of tasks may differ month to month, our obligation to perform substantially remains the same.

•Third party administration revenue is recognized over the contract period as these services are provided to clients continuously throughout the term of the arrangement. Our clients benefit from each

month of service on its own, and although the volume of tasks may differ month to month, our obligation to perform substantially remains the same.

•Actuarial revenue is recognized over the contract period with performance measured in hours in relation to the expected total hours. Under certain defined benefit plan administration arrangements, we charge new clients an initial, non-refundable, set-up fee as part of a multi-year service agreement. Revenue and costs related to the set-up fees are deferred and recognized over the life of the contract or the expected customer relationship, whichever is longer.

Revenue related to payroll processing consists of a (i) fixed fee or (ii) variable fee based on a price per employee or check processed. Revenue is recognized when the actual payroll processing occurs. Our customers benefit from each month of service on its own and although volume and the variability may differ month to month, our obligation to perform substantially remains the same.

Non-core Benefits and Insurance Services consists of transactional businesses that tend to fluctuate. These include life insurance, talent and compensation services.

National Practices

Managed networking, hardware services revenue consists of installation, maintenance and repair of computer hardware. These services are charged to a single customer based on cost plus an agreed-upon markup percentage, which has existed since 1999.

National Practices consulting revenue is based upon a fixed fee, an hourly rate, or outcome-based. Revenue for fixed fee and time and expense arrangements is recognized over the performance period based upon actual hours incurred, while revenue for outcome-based arrangements is recognized similar to the outcome-based arrangements in the Financial Services practice group.

Transaction Price Allocated to Future Obligations - The revenue recognition standard requires the disclosure of the aggregate amount of transaction price allocated to performance obligations that have not yet been satisfied as of the reporting date. The guidance provides certain practical expedients that limit this requirement, including performance obligations that are part of a contract that is one year or less. Since the majority of our contracts are one year or less, we have applied this practical expedient related to quantifying remaining performance obligations. In regards to contracts with terms in excess of one year, certain contract periods related to our government healthcare consulting, group health and benefits consulting, and property and casualty insurance businesses have an original specified contract duration in excess of one year, however, the agreements provide CBIZ and the client with the right to cancel or terminate the contract with no substantial penalty. We have applied the provisions of Topic 606 and the FASB Transition Resource Group memo number 10-14, and note that the definition of contract duration does not extend beyond the goods and services already transferred for contracts that provide both the Company and the client with the right to cancel or terminate the contract with no substantial penalty.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Commitments and Contingencies	Dec. 31, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Acquisitions - The purchase price that we normally pay for businesses and client lists consists of two components: an up-front non-contingent portion, and a portion which is contingent upon the acquired businesses or client lists’ future performance. The fair value of the contingent purchase price consideration is recorded at the date of acquisition and re-measured each reporting period until the liability is settled. Shares of our common stock that are issued in connection with acquisitions may be contractually restricted from sale for periods up to one year. Acquisitions are further disclosed in Note 18, Business Combinations. Indemnifications - We have various agreements in which we may be obligated to indemnify the other party with respect to certain matters. Generally, these indemnification clauses are included in contracts arising in the normal course of business under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations, warranties, covenants or agreements, related to matters such as title to assets sold and certain tax matters. Payment by us under such indemnification clauses are generally conditioned upon the other party making a claim. Such claims are typically subject to challenge by us and to dispute resolution procedures specified in the particular contract. Further, our obligations under these agreements may be limited in terms of time and/or amount and, in some instances, we may have recourse against third parties for certain payments made by us. It is not possible to predict the maximum potential amount of future payments under these indemnification agreements due to the conditional nature of our obligations and the unique facts of each particular agreement. Historically, we have not made any payments under these agreements that have been material individually or in the aggregate. As of December 31, 2023, we were not aware of any obligations arising under indemnification agreements that would require material payments, and therefore have not recorded a liability. Employment Agreements - We maintain severance and employment agreements with certain of our executive officers, whereby such officers may be entitled to payment in the event of termination of their employment. We also have arrangements with certain non-executive employees which may include severance and other employment provisions. We accrue for amounts payable under these contracts and arrangements as triggering events occur and obligations become known. During the years ended December 31, 2023, 2022 and 2021, payments under such contracts and arrangements were not material. 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 $3.5 million and $5.0 million at December 31, 2023 and 2022, respectively. In addition, we provide license bonds to various state agencies to meet certain licensing requirements. The amount of license bonds outstanding was $2.3 million and $2.3 million at December 31, 2023 and 2022, 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 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 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. 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 addition to the item 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.
