Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]

Item 1C. Cybersecurity.

We have implemented a cybersecurity program to assess, identify, and manage risks from cybersecurity threats that could adversely and materially affect the confidentiality, integrity, and availability of our information and information systems. We maintain administrative, technical, and physical safeguards designed to protect the security and privacy of confidential, personal and proprietary information. Our cybersecurity program is aligned with notable control frameworks such as the NIST CSF (National Institute of Standards and Technology Cybersecurity Framework) and ISO (International Organization for Standardization) 27001.

Our cybersecurity program leverages people, processes, and technology to identify and respond to cybersecurity threats. We have a global incident response capability supported by our Security Operations Center (which we refer to as SOC) team, a managed security service provider (MSSP) and our global Cybersecurity Incident Response Team (which we refer to as CSIRT), which provides threat detection and incident response.

We maintain a global cybersecurity incident response plan and related playbooks, for execution by the SOC team and CSIRT, in coordination with internal and external stakeholders, as applicable. Significant incidents are escalated to a cross-departmental team to assess materiality based on qualitative and quantitative factors. This team consists of executives representing core business functions, including, among others, information technology, legal, finance, accounting, data protection and business divisions, in consultation with third-party advisors, as applicable. We undertake periodic leadership tabletop exercises and periodic adversarial (“red team”) exercises simulating incident response under common risk scenarios. As an acquisitive organization, we have also established a program to increase our visibility into the cybersecurity environment of acquisition targets prior to closing.

We have established a dedicated vendor assessment team, which employs systems and processes designed to oversee, identify, and reduce the potential impact of a security incident at a third-party vendor, service provider or customer or that otherwise implicates the third-party technology and systems we use. We also require cybersecurity insurance coverage for vendors whose services or products may present a cybersecurity risk.

We continuously test and assess our cybersecurity posture, including through annual third-party risk assessments performed by reputable assessors, consultants and auditors. A global FAIR (Factor Analysis of Information Risk) assessment is conducted at least annually to update our cybersecurity risks and corresponding mitigations.

Our employees complete training on data security and our policies when they join us and annually thereafter. We review the content of our mandatory training annually, and provide access to a comprehensive set of supplemental training.

Our Chief Information Security Officer (CISO), working together with our Chief Information Officer (CIO), oversees a team of employees dedicated to cybersecurity. Our CISO receives ongoing updates from the cybersecurity team regarding the prevention, detection, mitigation, and remediation of cybersecurity incidents and regularly reports to the CIO. Our CISO is an active member of our management-level enterprise risk management committee, which has broad oversight of the company’s enterprise risks, including cybersecurity risks. In addition, our CIO and CISO both attend regular meetings of the executive officer team, including our Chief Executive Officer, Chief Financial Officer, General Counsel and other senior executive officers, dedicated to compliance and risk, and report on cybersecurity matters as appropriate. Our Board of Directors has delegated primary responsibility for the oversight of cybersecurity matters to its Risk and Compliance Committee; however, the full board reviews significant cybersecurity matters as appropriate. Our CIO and CISO report on cybersecurity and information security at each quarterly meeting of the Risk and Compliance Committee.

We, including our third-party vendors, have experienced cybersecurity incidents and threats and may continue to experience them in the future. Based on the information available as of the date of this Annual Report on Form 10-K, we believe that during the last three fiscal years risks from cybersecurity threats, including as a result of previous cybersecurity incidents, have not materially affected us, including our business strategy, results of operations or financial condition, and as of the date of this

Annual Report on Form 10-K, the Company is not aware of any material risks from cybersecurity threats that are reasonably likely to do so. However, we cannot eliminate all risks from cybersecurity threats or provide assurances that the Company will not be materially affected by such risks in the future. Due to evolving cybersecurity threats, we may not be able to protect all information systems and, as an acquisitive organization, integrating information systems as we acquire new businesses may expose us to unexpected liabilities or increase our vulnerability. There can be no guarantee that our policies, programs and controls, and those of our third-party vendors, including those described in this section, will be sufficient to protect our information, information systems or other property. Additional information on cybersecurity risks we face is discussed in Item 1A of Part I, “Risk Factors,” which should be read in conjunction with the foregoing information.

Cybersecurity Risk Board of Directors Oversight [Text Block] Our Board of Directors has delegated primary responsibility for the oversight of cybersecurity matters to its Risk and Compliance Committee; however, the full board reviews significant cybersecurity matters as appropriate.

Nature of Operations

Arthur J. Gallagher & Co. and its subsidiaries, collectively referred to herein as we, our, us or the Company, provide insurance brokerage, consulting and third party claims settlement and administration services to both domestic and international entities. We have three reportable segments: brokerage, risk management and corporate. Our brokers, agents and administrators act as intermediaries between underwriting enterprises and our clients.

Our brokerage segment operations provide brokerage and consulting services to entities of all types, including commercial, nonprofit, public sector entities and to a lesser extent, individuals, in the areas of insurance and reinsurance placements, risk of loss management and management of employer sponsored benefit programs. Our risk management segment operations provide contract claim settlement, claim administration, loss control services and risk management consulting for commercial, nonprofit, captive and public sector entities, and various other organizations that choose to self-insure property/casualty coverages or choose to use a third-party claims management organization rather than the claim services provided by underwriting enterprises. The corporate segment reports the financial information related to our debt, external acquisition‑related expenses, other corporate costs and the impact of foreign currency translation. Legacy clean energy investments consist of our investments in limited liability companies that own or have owned 35 commercial clean coal production facilities that produced refined coal using Chem-Mod LLC’s proprietary technologies. We believe these operations produced refined coal that qualifies for tax credits under IRC Section 45.

We do not assume underwriting risk on a net basis, other than with respect to de minimis amounts necessary to provide minimum or regulatory capital insurance to organize captives, pools, specialized underwriters or risk-retention groups. Rather, capital necessary for covering losses is provided by underwriting enterprises.

Investment income and other revenues are primarily generated from our premium financing operations, our invested cash and restricted cash we hold on behalf of our clients, as well as clean energy investments. In addition, our share of the net earnings related to partially owned entities that are accounted for using the equity method is included in investment income.

Arthur J. Gallagher & Co., a global insurance brokerage, risk management and consulting services firm, is headquartered in Rolling Meadows, Illinois. The Company provides these services in approximately 130 countries around the world through its owned operations and a network of correspondent brokers and consultants.

Basis of Presentation

The accompanying consolidated financial statements include our accounts and all of our majority-owned subsidiaries (50% or greater ownership). Substantially all of our investments in partially owned entities in which our ownership is less than 50% are accounted for using the equity method based on the legal form of our ownership interest and the applicable ownership percentage of the entity. However, in situations where a less than 50%-owned investment has been determined to be a variable interest entity and we are deemed to be the primary beneficiary in accordance with the variable interest model of consolidation, we will consolidate the investment into our consolidated financial statements. For partially owned entities accounted for using the equity method, our share of the net earnings of these entities is included in consolidated net earnings. All material intercompany accounts and transactions have been eliminated in consolidation.

In the preparation of our consolidated financial statements as of December 31, 2024, management evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date on which the financial statements were issued for potential recognition and/or disclosure in the notes therein.

Use of Estimates

The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These accounting principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses, and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements. We periodically evaluate our estimates and assumptions, including those relating to the valuation of goodwill and other intangible assets, right-of-use assets, investments, income taxes, revenue recognition, deferred costs, stock-based compensation, claims handling obligations, retirement plans, litigation and contingencies. We base our estimates on historical experience and various assumptions that we believe to be reasonable based on specific circumstances. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

Revenue Recognition

Our revenues are derived from commissions and fees as primarily specified in a written contract, or unwritten business understanding, with our clients or underwriting enterprises. We also recognize investment income over time from our invested assets and invested assets we hold on behalf of our clients or underwriting enterprises.

BROKERAGE SEGMENT

Our brokerage segment generates revenues by:

(i)
Identifying, negotiating and placing all forms of insurance coverage, as well as providing data analytics, risk-shifting, risk-sharing and risk-mitigation consulting services, principally related to property/casualty, life, health, welfare and disability insurance. We also provide these services through, or in conjunction with, other unrelated agents and brokers, consultants and management advisors;
(ii)
Identifying, negotiating and placing all forms of reinsurance coverage, as well as providing capital markets services, including acting as underwriter, with respect to insurance linked securities, weather derivatives, capital raising and selected merger and acquisition advisory activities;
(iii)
Acting as an agent or broker for multiple underwriting enterprises by providing services such as sales, marketing, selecting, negotiating, underwriting, servicing and placing insurance coverage on their behalf;
(iv)
Providing consulting services related to health and welfare benefits, voluntary benefits, executive benefits, compensation, retirement planning, institutional investment and fiduciary, actuarial, compliance, private insurance exchange, human resource technology, communications and benefits administration; and
(v)
Providing management and administrative services to captives, pools, risk-retention groups, healthcare exchanges, small underwriting enterprises, such as accounting, claims and loss processing assistance, feasibility studies, actuarial studies, data analytics and other administrative services.

The vast majority of our brokerage contracts and service understandings are for a period of one year or less.

Commissions and fees

The primary source of revenues for our brokerage services is commissions from underwriting enterprises, based on a percentage of premiums paid by our clients, or fees received from clients based on an agreed level of service usually in lieu of commissions. These commissions and fees revenues are substantially recognized at a point in time on the effective date of the associated policies when control of the policy transfers to the client, as well as deferring certain revenues to reflect delivery of services over the contract period.

Commissions are fixed at the contract effective date and generally are based on a percentage of premiums for insurance coverage or employee headcount for employer sponsored benefit plans. Commissions depend upon a large number of factors, including the type of risk being placed, the particular underwriting enterprise’s demand, the expected loss experience of the particular risk of coverage, and historical benchmarks surrounding the level of effort necessary for us to place and service the insurance contract. Rather than being tied to the amount of premiums, fees are most often based on an expected level of effort to provide our services.

Whether we are paid a commission or a fee, the vast majority of our services are associated with the placement of an insurance (or insurance-like) contract. Accordingly, we recognize approximately 85% of our commission and fee revenues on the effective date of the underlying insurance contract. The amount of revenue we recognize is based on our costs to provide our services up and through that effective date, including an appropriate estimate of our profit margin on a portfolio basis (a practical expedient as defined in Topic 606). Based on the proportion of additional services we provide in each period after the effective date of the insurance contract, including an appropriate estimate of our profit margin, we recognize approximately 10% of our commission and fee revenues in the first three months, and the remaining 5% thereafter. These periods may be different than the underlying premium payment patterns of the insurance contracts, but the vast majority of our services are fully provided within one year of the insurance contract effective date.

For consulting and advisory services, we recognize our revenue in the period in which we provide the service or advice. For management and administrative services, our revenue is recognized ratably over the contract period consistent with the performance of our obligations, mostly over an annual term.

Supplemental revenues

Certain underwriting enterprises may pay us additional revenues for the volume of premium placed with them and for insights into our sales pipeline, our sales capabilities or our risk selection knowledge. These amounts are in excess of the commission and fee revenues discussed above, and not all business we place with underwriting enterprises is eligible for supplemental revenues. Unlike contingent revenues, discussed below, these revenues are primarily a fixed amount or fixed percentage of premium of the underlying eligible insurance contracts. For supplemental revenue contracts based on a fixed percentage of premium, our obligation to the underwriting enterprise is substantially completed upon the effective date of the underlying insurance contract and revenue is fully earned at that time. For supplemental revenue contracts based on a fixed amount, revenue is recognized ratably over the contract period consistent with the performance of our obligations, almost always over an annual term. We receive these revenues on a quarterly or annual basis.

Contingent revenues

Certain underwriting enterprises may pay us additional revenues for our sales capabilities, our risk selection knowledge, or our administrative efficiencies. These amounts are in excess of the commission or fee revenues discussed above, and not all business we place with participating underwriting enterprises is eligible for contingent revenues. Unlike supplemental revenues, also discussed above, these revenues are variable, generally based on growth, the loss experience of the underlying insurance contracts, and/or our efficiency in processing the business. We generally operate under calendar year contracts, but we do not receive these revenues from the underwriting enterprises until the following calendar year, generally in the first and second quarters, after verification of the performance indicators outlined in the contracts. Accordingly, during each reporting period, we must make our best estimate of amounts we have earned using historical averages and other factors to project such revenues. We base our estimates each period on a contract-by-contract basis where available. In certain cases, it is impractical to assess a very large number of smaller contingent revenue contracts, so we use a historical portfolio estimate in aggregate (a practical expedient as defined in Topic 606). Because our expectation of the ultimate contingent revenue amounts to be earned can vary from period to period, especially in contracts sensitive to loss ratios, our estimates might change significantly from quarter to quarter. For example, in circumstances where our revenues are dependent on a full calendar year loss ratio, adverse loss experience in the fourth quarter could not only negate revenue earnings in the fourth quarter, but also trigger the need to reverse revenues previously recognized during the prior quarters. Variable consideration is recognized when we conclude, based on all the facts

and information available at the reporting date, that it is probable that a significant revenue reversal will not occur in future periods.

Sub-brokerage costs

Sub-brokerage costs are excluded from our gross revenues in our determination of total revenues. Sub-brokerage costs represent commissions paid to sub-brokers related to the placement of certain business by our brokerage segment operations. We recognize this contra revenue in the same manner as the commission revenue to which it relates.

RISK MANAGEMENT SEGMENT

Revenues for our risk management segment are comprised of fees generally negotiated (i) on a per-claim or per-service basis, (ii) on a cost‑plus basis, or (iii) as performance-based fees. We also provide risk management consulting services that are recognized as the services are delivered.

Per-claim or per-service fees

Where we operate under a contract with our fee established on a per-claim or per-service basis, our obligation is to process claims for a term specified within the contract. Because it is impractical to recognize our revenues on an individual claim-by-claim basis, we recognize revenue plus an appropriate estimate of our profit margin on a portfolio basis by grouping claims with similar characteristics (a practical expedient as defined in Topic 606). We apply actuarially-determined, historical-based patterns to determine our future service obligations, without applying a present value discount.

Cost-plus fees

Where we provide services and generate revenues on a cost-plus basis, we recognize revenue over the contract period consistent with the performance of our obligations.

Performance-based fees

Certain clients pay us additional fee revenues for our efficiency in managing claims or on the basis of claim outcome effectiveness. These amounts are in excess of the fee revenues discussed above. These revenues are variable, generally based on performance metrics set forth in the underlying contracts. We generally operate under multi-year contracts with fiscal year measurement periods. We do not receive these fees, if earned, until the following year after verification of the performance metrics outlined in the contracts. Each period we base our estimates on a contract-by-contract basis. We must make our best estimate of amounts we have earned using historical averages and other factors to project such revenues. Variable consideration is recognized when we conclude that it is probable that a significant revenue reversal will not occur in future periods.

Reimbursements

Reimbursements represent amounts received from clients reimbursing us for certain third-party costs associated with providing our claims management services. In certain service partner relationships, we are considered a principal because we direct the third party, control the specified service and combine the services provided into an integrated solution. Given this principal relationship, we are required to recognize revenue gross and service partner vendor fees in the operating expense in our consolidated statement of earnings.

Deferred Costs

We incur costs to provide brokerage and risk management services. Those costs are either (i) costs to obtain a contract or (ii) costs to fulfill such contract, or (iii) all other costs.

(i)
Costs to obtain - we incur costs to obtain a contract with a client. Those costs would not have been incurred if the contract had not been obtained. Almost all of our costs to obtain are incurred prior to, or on, the effective date of the contract and consist primarily of incentive compensation we pay to our production employees. Our costs to obtain are expensed as incurred as described in Note 4 to these consolidated financial statements.
(ii)
Costs to fulfill - we incur costs to fulfill a contract (or anticipated contract) with a client. Those costs are incurred prior to the effective date of the contract and relate to fulfilling our primary placement obligations to our clients. Our costs to fulfill prior to the effective date are capitalized and amortized on the effective date. These fulfillment
activities include collecting underwriting information from our client, assessing their insurance needs and negotiating their placement with one or more underwriting enterprises. The majority of costs that we incur relate to compensation and benefits of our client service employees. Costs incurred during preplacement activities are expected to be recovered in the future. If the capitalized costs are no longer deemed to be recoverable, then they would be expensed.
(iii)
Other costs that are not costs to obtain or fulfill are expensed as incurred. Examples include other operating costs such as rent, utilities, management costs, overhead costs, legal and other professional fees, technology costs, insurance related costs, communication and advertising, and travel and entertainment. Depreciation, amortization and change in estimated acquisition earnout payable are expensed as incurred.

Investment Income

Investment income primarily includes interest (including revenue from our premium financing operations) and dividend income, which is accrued as it is earned. Net gains on divestitures represent one-time gains related to sales of brokerage related businesses, which are primarily recognized on a cash received basis.

Earnings per Share

Basic net earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the reporting period. Diluted net earnings per share is computed by dividing net earnings by the weighted average number of common and common equivalent shares outstanding during the reporting period. Common equivalent shares include incremental shares from dilutive stock options, which are calculated from the date of grant under the treasury stock method using the average market price for the period.

Cash and Cash Equivalents

Short-term investments, consisting principally of cash and money market accounts that have average maturities of 90 days or less, are considered cash equivalents.

Fiduciary Assets and Liabilities

Fiduciary assets represent cash held and insurance and reinsurance receivables that relate to our clients and are held on their behalf. Fiduciary liabilities represent the corresponding amounts that are owed to underwriting enterprises on behalf of our clients. In our capacity as an insurance broker, we collect premiums from insureds and, after deducting our commissions and/or fees, remit these premiums to underwriting enterprises. We hold unremitted insurance premiums in a fiduciary capacity until we disburse them, and the use of such funds is restricted by laws in certain states and foreign jurisdictions in which our subsidiaries operate. Various state and foreign agencies regulate insurance brokers and provide specific requirements that limit the type of investments that may be made with such funds. Accordingly, we invest these funds in cash and U.S. Treasury fund accounts. We can earn interest income on these unremitted funds, which is included in investment income in the accompanying consolidated statement of earnings. These unremitted amounts are included in fiduciary assets in the accompanying consolidated balance sheet, with the related liability included in fiduciary liabilities. Additionally, several of our foreign subsidiaries are required by various foreign agencies to meet certain liquidity and solvency requirements. We were in compliance with these requirements at December 31, 2024. This restricted cash is included in cash and cash equivalents net in the accompanying consolidated balance sheet.

Related to our third party administration business and in certain of our brokerage operations, we are responsible for client claim funds that we hold in a fiduciary capacity. We do not earn any interest income on the funds held. These client funds have been included in fiduciary assets, along with a corresponding liability in fiduciary liabilities in the accompanying consolidated balance sheet.

Accounts Receivable

Accounts receivable, net in the accompanying consolidated balance sheet includes accrued agency billed commissions, fees, supplemental commissions, direct bill commissions and contingent commission receivables due to the Company. Accounts receivable are net of allowances for estimated policy cancellations and doubtful accounts. The allowance for estimated policy cancellations was $13.3 million and $9.9 million at December 31, 2024 and 2023, respectively, which represents a reserve for future reversals in commission and fee revenues related to the potential cancellation of client insurance policies that were in force as of each year end. The allowance for doubtful accounts was $21.8 million and $23.0 million at December 31, 2024 and

2023, respectively. We establish the allowance for estimated policy cancellations through a charge to revenues and the allowance for doubtful accounts through a charge to operating expenses. Both of these allowances are based on estimates and assumptions using historical data to project future experience. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. We periodically review the adequacy of these allowances and make adjustments as necessary.

Derivative Instruments

We are exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, we enter into various derivative instruments that reduce these risks by creating offsetting exposures. In the normal course of business, we are exposed to the impact of foreign currency fluctuations that impact our results of operations and cash flows. We utilize a foreign currency risk management program involving foreign currency derivatives that consist of several monthly put/call options designed to hedge a portion of our future foreign currency disbursements through various future payment dates. To mitigate the counterparty credit risk we only enter into contracts with major financial institutions based upon their credit ratings and other factors. These derivative instrument contracts are cash flow hedges that qualify for hedge accounting and primarily hedge against fluctuations between changes in the British pound and Indian Rupee versus the U.S. dollar. Changes in fair value of the derivative instruments are reflected in other comprehensive earnings in the accompanying consolidated balance sheet. The impact of the hedge at maturity is recognized in the income statement as a component of investment income, compensation and operating expenses depending on the nature of the hedged item. We enter into various long-term debt agreements. We use interest rate derivatives, typically swaps, to reduce our exposure to the effects of interest rate fluctuations on the forecasted interest rates for up to three years into the future. These derivative instrument contracts are periodically monitored for hedge ineffectiveness, the amount of which has not been material to the accompanying consolidated financial statements. We do not use derivatives for trading or speculative purposes.

Premium Financing

Seven subsidiaries of the brokerage segment make short-term loans (generally with terms of twelve months or less) to our clients to finance premiums. These premium financing contracts are structured to minimize potential bad debt expense to us. Such receivables are generally considered delinquent after seven days of the payment due date. In normal course, insurance policies are canceled within one month of the contractual payment due date if the payment remains delinquent. We recognize interest income as it is earned over the life of the contract using the “level-yield” method. Unearned interest related to contracts receivable is included in the receivable balance in the accompanying consolidated balance sheet. The outstanding loan receivable balance was $616.1 million and $685.7 million at December 31, 2024 and 2023, respectively.

Fixed Assets

We carry fixed assets at cost, less accumulated depreciation, in the accompanying consolidated balance sheet. 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. Depreciation for fixed assets is computed using the straight-line method over the following estimated useful lives:

 

 

 

Useful Life

Office equipment

 

Three to ten years

Furniture and fixtures

 

Two to ten years

Computer equipment

 

Three to five years

Building

 

Fifteen to forty years

Software

 

Three to five years

Leasehold improvements

 

Shorter of the lease term or useful life of the asset

 

Intangible Assets

Intangible assets represent the excess of cost over the estimated fair value of net tangible assets of acquired businesses. Our primary intangible assets are classified as either goodwill, expiration lists, non-compete agreements or trade names. Expiration lists, non‑compete agreements and trade names are amortized using the straight-line method over their estimated useful lives (two to fifteen years for expiration lists, two to six years for non-compete agreements and two to fifteen years for trade names), while goodwill is not subject to amortization. The establishment of goodwill, expiration lists, non-compete agreements and trade

names and the determination of estimated useful lives are primarily based on valuations we receive from qualified independent appraisers. The calculations of these amounts are based on estimates and assumptions using historical and projected financial information and recognized valuation methods. Different estimates or assumptions could produce different results. We carry identifiable intangible assets at cost, less accumulated amortization, in the accompanying consolidated balance sheet.

We review all of our intangible assets for impairment periodically (at least annually for goodwill) and whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. We perform such impairment reviews at the division (i.e., reporting unit) level with respect to goodwill and at the business unit level for amortizable intangible assets. While goodwill is not amortizable, it is tested for impairment at least annually in the fourth quarter, and more frequently if there are indicators of impairment or whenever business circumstances suggest that the carrying value of goodwill may not be recoverable. We may initially perform a qualitative analysis to determine if it is more likely than not that the goodwill balance is impaired. If a qualitative assessment is not performed or if a determination is made that it is not more likely than not that the fair value of the reporting unit exceeds its carrying amount, then we will perform a quantitative analysis. The fair value of each reporting unit is compared to its carrying value. If the fair value of the reporting unit is less than its carrying value, a non-cash impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit’s fair value with the loss not exceeding the total amount of goodwill allocated to that reporting unit. We completed our 2024 annual assessment in the fourth quarter and concluded goodwill was not impaired, as the fair value of each reporting unit exceeded its carrying value.

The carrying value of amortizable intangible assets attributable to each business or asset group is periodically reviewed by management to determine if there are events or changes in circumstances that would indicate that its carrying amount may not be recoverable. Accordingly, if there are any such changes in circumstances during the year, we assess the carrying value of the amortizable intangible assets by considering the estimated future undiscounted cash flows generated by the corresponding business or asset group. Any impairment identified through this assessment may require that the carrying value of related amortizable intangible assets be adjusted and charged against current period earnings as a component of amortization expense. Based on the results of impairment reviews in 2024, 2023 and 2022, we wrote off $19.4 million, $3.5 million and $2.0 million, respectively, of amortizable intangible assets primarily related to acquisitions (made prior to 2023) of our brokerage and risk management segments, which is included in amortization expense in the accompanying consolidated statement of earnings. The determinations of impairment indicators and fair value are based on estimates and assumptions related to the amount and timing of future cash flows and future interest rates. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein.

Income Taxes

Our tax rate reflects the statutory tax rates applicable to our taxable earnings and tax planning in the various jurisdictions in which we operate. Significant judgment is required in determining the annual effective tax rate and in evaluating uncertain tax positions. We report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We evaluate our tax positions using a two-step process. The first step involves recognition. We determine whether it is more likely than not that a tax position will be sustained upon tax examination based solely on the technical merits of the position. The technical merits of a tax position are derived from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings and case law) and their applicability to the facts and circumstances of the position. If a tax position does not meet the “more likely than not” recognition threshold, we do not recognize the benefit of that position in the financial statements. The second step is measurement. A tax position that meets the “more likely than not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that has a likelihood of greater than 50% of being realized upon ultimate resolution with a taxing authority.

Uncertain tax positions are measured based upon the facts and circumstances that exist at each reporting period and involve significant management judgment. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. We recognize interest and penalties, if any, related to unrecognized tax benefits in our provision for income taxes.

Tax law requires certain items to be included in our tax returns at different times than such items are reflected in the financial statements. As a result, the annual tax expense reflected in our consolidated statements of earnings is different than that reported in our tax returns. Some of these differences are permanent, such as expenses that are not deductible in our tax returns, and some differences are temporary and reverse over time, such as depreciation expense and amortization expense deductible for income tax purposes. Temporary differences create deferred tax assets and liabilities. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which a tax payment has been deferred, or expense which has been deducted

in the tax return but has not yet been recognized in the financial statements. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which a benefit has already been recorded in the financial statements.

We establish or adjust valuation allowances for deferred tax assets when we estimate that it is more likely than not that future taxable income will be insufficient to fully use a deduction or credit in a specific jurisdiction. In assessing the need for the recognition of a valuation allowance for deferred tax assets, we consider whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized and adjust the valuation allowance accordingly. We evaluate all significant available positive and negative evidence as part of our analysis. Negative evidence includes the existence of losses in recent years. Positive evidence includes the forecast of future taxable income by jurisdiction, tax-planning strategies that would result in the realization of deferred tax assets and the presence of taxable income in prior carryback years. The underlying assumptions we use in forecasting future taxable income require significant judgment and take into account our recent performance. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences are deductible or creditable.

Fair Value of Financial Instruments

Fair value accounting establishes a framework for measuring fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). This framework includes a fair value hierarchy that prioritizes the inputs to the valuation technique used to measure fair value.

The classification of a financial instrument within the valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels of the hierarchy in order of priority of inputs to the valuation technique are defined as follows:

Level 1 - Valuations are based on unadjusted quoted prices in active markets for identical financial instruments;
Level 2 - Valuations are based on quoted market prices, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument; and
Level 3 - Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management’s own assumptions about the assumptions a market participant would use in pricing the financial instrument.

The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety.

The carrying amounts of financial assets and liabilities reported in the accompanying consolidated balance sheet for cash and cash equivalents, fiduciary assets, accounts receivable, other current assets, fiduciary liabilities, accrued compensation and other accrued liabilities and deferred revenue - current, at December 31, 2024 and 2023, approximate fair value because of the short-term duration of these instruments. See Note 3 to these consolidated financial statements for the fair values related to the establishment of intangible assets and the establishment and adjustment of earnout payables. See Note 7 to these consolidated financial statements for the fair values related to borrowings outstanding at December 31, 2024 and 2023 under our debt agreements. See Note 12 to these consolidated financial statements for the fair values related to investments at December 31, 2024 and 2023 under our defined benefit pension plan.

Litigation

We are the defendant in various legal actions related to claims, lawsuits and proceedings incidental to the nature of our business. We record liabilities for loss contingencies, including legal costs (such as fees and expenses of external lawyers and other service providers) to be incurred, when it is probable that a liability has been incurred on or before the balance sheet date and the amount of the liability can be reasonably estimated. We do not discount such contingent liabilities. To the extent recovery of such losses and legal costs is probable under our insurance programs, we record estimated recoveries concurrently with the losses recognized. Significant management judgment is required to estimate the amounts of such contingent liabilities and the related insurance recoveries. In order to assess our potential liability, we analyze our litigation exposure based on available information, including consultation with outside counsel handling the defense of these matters. As these liabilities are uncertain by their

nature, the recorded amounts may change due to a variety of different factors, including new developments in, or changes in approach, such as changing the settlement strategy as applicable to each matter.

Retention Bonus Arrangements

In connection with the hiring and retention of both new talent and experienced personnel, including our senior management, brokers and other key personnel, we have entered into various agreements with key employees setting up the conditions for the cash payment of certain retention bonuses. These bonuses are an incentive for these employees to remain with the Company, for a fixed period of time, to allow us to capitalize on their knowledge and experience. We have various forms of retention bonus arrangements; some are paid up front and some are paid at the end of the term, but all are contingent upon successfully completing a minimum period of employment. A retention bonus that is paid to an employee upfront that is contingent on a certain minimum period of employment, will be initially classified as a prepaid asset and amortized to compensation expense as the future services are rendered over the duration of the stay period. A retention bonus that is paid to an employee at the end of the term that is contingent on a certain minimum period of employment, will be accrued as a liability through compensation expense as the future services are rendered over the duration of the stay period. If an employee leaves prior to the required time frame to earn the retention bonus outright, then all or any portion that is ultimately unearned or refundable, and recovered by the Company if prepaid, is forfeited and reversed through compensation expense.

Stock-Based Compensation

We have several employee equity-settled and cash-settled share-based compensation plans. Equity-settled share-based payments to employees include grants of stock options, performance stock units and restricted stock units and are measured based on estimated grant date fair value. We have elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the dates of grant. Performance stock units are measured on the probable outcome of the performance conditions applicable to each grant. Restricted stock units are measured based on the fair market values of the underlying stock on the dates of grant. Shares are issued on the vesting dates net of the minimum statutory tax withholding requirements, as applicable, to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number of performance stock units and restricted stock units outstanding. Furthermore, we record the liability for withholding amounts to be paid by us as a reduction to additional paid-in capital when paid.

Cash-settled share-based payments to employees include awards under our Performance Unit Program and stock appreciation rights. The fair value of the amount payable to employees in respect of cash-settled share-based payments is recognized as compensation expense, with a corresponding increase in liabilities, over the vesting period. The liability is remeasured at each reporting date and at settlement date. Any changes in fair value of the liability are recognized as compensation expense.

We recognize share-based compensation expense over the requisite service period for awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs from original estimates.

Employee Stock Purchase Plan

We have an employee stock purchase plan (which we refer to as the ESPP), under which the sale of 8.0 million shares of our common stock has been authorized. Eligible employees may contribute up to 15% of their compensation towards the quarterly purchase of our common stock at a purchase price equal to 95% of the lesser of the fair market value of our common stock on the first business day or the last business day of the quarterly offering period. Eligible employees may annually purchase shares of our common stock with an aggregate fair market value of up to $25,000 (measured as of the first day of each quarterly offering period of each calendar year), provided that no employee may purchase more than 2,000 shares of our common stock under the ESPP during any calendar year. At December 31, 2024, 4.7 million shares of our common stock was reserved for future issuance under the ESPP.

Defined Benefit Pension Plans

We recognize in our consolidated balance sheet, an asset for our defined benefit pension plans’ overfunded status or a liability for our plans’ underfunded status. We recognize changes in the funded status of our defined benefit pension plans in comprehensive earnings in the year in which the changes occur. We use December 31 as the measurement date for our plans’ assets and benefit obligations. See Note 12 to these consolidated financial statements for additional information required to be disclosed related to our defined benefit pension plans.

2. Effect of New Accounting Pronouncements

Segment Reporting

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires that an entity report segment information in accordance with Topic 280, Segment Reporting. The amendment in the ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted this ASU as of December 31, 2024, which affected our segment disclosures. See Note 19 to these consolidated financial statements for further detail regarding the impact of this ASU.

Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The amendment in the ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024. We are currently evaluating the impact of the new standard on our consolidated financial statements which is expected to result in enhanced disclosures.

Climate Risk Disclosures

In March 2024, the SEC issued final climate-related disclosure rules that will require disclosure of material climate-related risks and material direct greenhouse gas emissions from operations owned or controlled (Scope 1) and/or material indirect greenhouse gas emissions from purchased energy consumed in owned or controlled operations (Scope 2). Additionally, the rules require disclosure in the notes to the financial statements of the effects of severe weather events and other natural conditions, subject to certain materiality thresholds. The disclosure requirements were scheduled to begin phasing in for annual reports and registration statements including financial information with respect to annual periods beginning in calendar year 2025. On April 4, 2024, the SEC issued an order staying the rules during the pendency of a number of legal challenges to the rules’ validity. We are continuing to monitor these developments while evaluating the impact of the rules on our consolidated financial statements, which are expected to result in additional disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting–Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) included within income statement expense captions. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard updates are to be applied prospectively with the option for retrospective application. We are currently evaluating the impact of adoption of the standard update on its financial statement disclosures.

On December 7, 2024, we signed a definitive agreement to acquire all of the issued and outstanding stock of Dolphin Topco, Inc., the holding company of AssuredPartners, Inc., a Delaware corporation (together with its subsidiaries, “AssuredPartners”) for gross consideration of $13.45 billion. The transaction is subject to customary regulatory approval, standard closing conditions and is expected to close during first quarter 2025. AssuredPartners is a leading U.S. insurance broker with client capabilities across commercial property/casualty, specialty, employee benefits and personal lines with operations in the U.K. and Ireland. We expect to fund the transaction using $8.5 billion of cash raised in our December 11, 2024 follow-on common stock offering and $5.0 billion of cash borrowed in our December 19, 2024 senior notes issuance (which we refer to, together with the follow-on common stock offering, as the AssuredPartners Financing). On January 7, 2025, we received an additional $1.28 billion of cash due to the exercise by the underwriters of the overallotment provision related to the follow-on common stock offering.

Common shares issued in connection with acquisitions are valued at closing market prices as of the effective date of the applicable acquisition or on the days when the shares are issued, if purchase consideration is deferred. We record escrow deposits that are returned to us as a result of adjustments to net assets acquired as reductions of goodwill when the escrows are settled. The maximum potential earnout payables disclosed in the foregoing table represent the maximum amount of additional consideration that could be paid pursuant to the terms of the purchase agreement for the applicable acquisition. The amounts recorded as earnout payables, which are primarily based upon the estimated future operating results of the acquired entities over a two- to three-year period subsequent to the acquisition date, are measured at fair value as of the acquisition date and are included on that basis in the recorded purchase price consideration in the foregoing table. We will record subsequent changes in these estimated earnout obligations, including the accretion of discount, in our consolidated statement of earnings when incurred.

The fair value of these earnout obligations is based on the present value of the expected future payments to be made to the sellers of the acquired entities in accordance with the provisions outlined in the respective purchase agreements, which is a Level 3 fair value measurement. In determining fair value, we estimated the acquired entity’s future performance using financial projections developed by management for the acquired entity and market participant assumptions that were derived for revenue growth and/or profitability. Revenue growth rates generally ranged from 3.0% to 19.0% for our 2024 acquisitions. We estimated future payments using the earnout formula and performance targets specified in each purchase agreement and the financial projections just described. We then discounted these payments to present value using a risk-adjusted rate that takes into consideration market‑based rates of return that reflect the ability of the acquired entity to achieve the targets. The discount rates generally ranged from 7.1% to 9.0% for our 2024 acquisitions. In some instances, the fair value of these earnout obligations can be based on other valuation methods including the Black-Scholes Option Pricing Method or Monte Carlo Simulation method. Changes in financial projections, market participant assumptions for revenue growth and/or profitability, or the risk-adjusted discount rate, would result in a change in the fair value of recorded earnout obligations.

During 2024, 2023 and 2022, we recognized $61.7 million, $76.6 million and $61.0 million respectively, of expense in our consolidated statement of earnings related to the accretion of the discount recorded for earnout obligations in connection with our acquisitions. In addition, during 2024, 2023 and 2022, we recognized $35.7 million of income, $300.7 million of expense and $22.0 million of expense, respectively, related to net adjustments in the estimated fair value of the liability for earnout obligations in connection with revised assumptions due to changes in interest rates volatility and other assumptions and projections of future performance for 91, 80 and 89 acquisitions, respectively. The net adjustments during 2024, include changes made to the estimated fair value of the Willis Re acquisition earnout and reflect updated assumptions as of December 31, 2024. The aggregate amount of maximum earnout obligations related to acquisitions made in 2021 and subsequent years was $1,998.2 million as of December 31, 2024, of which $1,302.0 million was recorded in the consolidated balance sheet as of that date based on the estimated fair value of the expected future payments to be made, of which approximately $511.9 million can be settled in cash or common stock at our option and $790.1 million must be settled in cash. The aggregate amount of maximum earnout obligations related to acquisitions made in 2020 and subsequent years was $2,009.8 million as of December 31, 2023, of which $1,294.2 million was recorded in the consolidated balance sheet as of that date based on the estimated fair value of the expected future payments to be made, of which approximately $564.8 million can be settled in cash or common stock at our option and $729.4 million must be settled in cash.

Among other things, these acquisitions allow us to expand into desirable geographic locations, further extend our presence in the retail and wholesale insurance and reinsurance brokerage markets and increase the volume of general services currently provided. The excess of the purchase price over the estimated fair value of the tangible net assets acquired at the acquisition date was allocated to goodwill, expiration lists, non-compete agreements and trade names in the amounts of $837.2 million, $791.5 million, $23.6 million and $1.9 million, respectively, within the brokerage and risk management segments.

The fair value of the tangible assets and liabilities for each applicable acquisition at the acquisition date approximated their carrying values. In general, the fair value of expiration lists was established using the excess earnings method, which is an income approach based on estimated financial projections developed by management for each acquired entity using market participant assumptions. Revenue growth and attrition rates generally ranged from 0.7% to 5.3% and 5.0% to 13.5% for our 2024 and 2023 acquisitions, respectively, for which valuations were performed in 2024. We estimate the fair value as the present value of the benefits anticipated from ownership of the subject expiration list in excess of returns required on the investment in contributory assets necessary to realize those benefits. The rate used to discount the net benefits was based on a risk-adjusted rate that takes into consideration market-based rates of return and reflects the risk of the asset relative to the acquired business. These discount rates generally ranged from 9.5% to 11.5% for our 2024 and 2023 acquisitions, for which valuations were performed in 2024. The fair value of non-compete agreements was established using the profit differential method, which is an income approach based on estimated financial projections developed by management for the acquired company using market participant assumptions and various non-compete scenarios.

 

Provisional estimates of fair value are established at the time of each acquisition and are subsequently reviewed and finalized within the first year of operations subsequent to the acquisition date to determine the necessity for adjustments. During this period, we may use independent third-party valuation specialists to assist us in finalizing the fair value of assets acquired and liabilities assumed. Fair value adjustments, if any, are most common to the values established for amortizable intangible assets, including expiration lists, non‑compete agreements, acquired software, and for earnout liabilities, with the offset to goodwill, net of any income tax effect.

Expiration lists, non-compete agreements and trade names related to our acquisitions are amortized using the straight-line method over their estimated useful lives (two to fifteen years for expiration lists, two to six years for non-compete agreements and two to fifteen years for trade names), while goodwill is not subject to amortization. We use the straight-line method to amortize these intangible assets because the pattern of their economic benefits cannot be reasonably determined with any certainty. We review all of our identifiable intangible assets for impairment periodically (at least annually) and whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. In reviewing identifiable intangible assets, if the undiscounted future cash flows were less than the carrying amount of the respective (or underlying) asset, an indicator of impairment would exist and further analysis would be required to determine whether or not a loss would need to be charged against current period earnings as a component of amortization expense.

Of the $791.5 million of expiration lists, $23.6 million of non-compete agreements and $1.9 million of trade names related to the 2024 acquisitions, $239.8 million, $16.7 million and $0.5 million, respectively, is not expected to be deductible for income tax purposes. Accordingly, we recorded a deferred tax liability of $64.9 million, and a corresponding amount of goodwill, in 2024 related to the nondeductible amortizable intangible assets.

Our consolidated financial statements for the year ended December 31, 2024 include the operations of the acquired entities from their respective acquisition dates. The following is a summary of the unaudited pro forma historical results, as if these entities had been acquired at January 1, 2023 (in millions, except per share data):

The unbilled receivables, which are included in premium and fees receivable in our consolidated balance sheet, primarily relate to our rights to consideration for work completed but not billed at the reporting date. These are transferred to the receivables when the client is billed. The deferred contract costs represent the costs we incur to fulfill a new or renewal contract with our clients prior to the effective date of the contract. These costs are expensed on the contract effective date. The deferred revenue in the consolidated balance sheet included amounts that represent the remaining performance obligations under our contracts and amounts collected related to advanced billings and deposits received from customers that may or may not ultimately be

recognized as revenues in the future. Deposits received from customers could be returned to the customers based on lesser actual transactional volume than originally billed volume.

Deferred contract costs were $206.8 million and $169.1 million as of December 31, 2024 and 2023, respectively. Capitalized fulfillment costs are amortized to expense on the contract effective date. The amount of amortization of the deferred contract costs was $666.0 million and $570.8 million for the years ended December 31, 2024 and 2023, respectively.

We have applied the practical expedient to recognize the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that we otherwise would have recognized is one year or less for our brokerage segment. These costs are included in compensation and operating expenses in our consolidated statement of earnings.

Senior Notes - On December 19, 2024, we closed and funded an offering of $5,000.0 million of unsecured senior notes in five tranches. The $750.0 million aggregate principal amount of 4.60% Senior Notes is due in 2027, $750.0 million aggregate principal amount of 4.85% Senior Notes is due in 2029, $500.0 million aggregate principal amount of 5.00% Senior Notes is due in 2032, $1,500.0 million aggregate principal amount of 5.15% Senior Notes is due in 2035 and $1,500.0 million aggregate principal amount 5.55% Senior Notes is due in 2055. The weighted average interest rate is 5.25% per annum after giving effect to underwriting costs and a net hedge gain. During 2024, we entered into a pre-issuance interest rate hedging transaction related to these notes. We realized a net cash gain of approximately $4.1 million on the hedging transactions that will be recognized on a pro rata basis as a decrease to our reported interest expense over ten years. We expect to use the net proceeds of this offering to fund a portion of the cash consideration payable in connection with the AssuredPartners transaction and, to the extent that any proceeds remain thereafter, or if the AssuredPartners transaction is not completed, for general corporate purposes including other acquisitions.

On February 12, 2024, we closed and funded an offering of $1,000.0 million of unsecured senior notes in two tranches. The $500.0 million aggregate principal amount of 5.45% Senior Notes is due in 2034 and $500.0 million aggregate principal amount of 5.75% Senior Notes is due in 2054. The weighted average interest rate is 5.71% per annum after giving effect to underwriting costs and a net hedge loss. During 2023, we entered into a pre-issuance interest rate hedging transaction related to these notes. We realized a net cash loss of approximately $1.4 million on the hedging transactions that will be recognized on a pro rata basis as an increase to our reported interest expense over ten years. We used the proceeds of these offerings to fund acquisitions, earnout payments related to acquisitions and general corporate purposes.

On November 2, 2023, we closed and funded an offering of $1,000.0 million of unsecured senior notes in two tranches. The $400.0 million aggregate principal amount of 6.50% Senior Notes is due 2034 and $600.0 million aggregate principal amount of 6.75% Senior Notes is due 2054. The weighted average interest rate is 5.97% per annum after giving effect to underwriting costs and a net hedge gain. During 2021 through 2023, we entered into a pre-issuance interest rate hedging transaction related to these notes. We realized a net cash gain of approximately $128.0 million on the hedging transactions that will be recognized on a pro rata basis as a decrease to our reported interest expense over ten years. We used the proceeds of these offerings to fund acquisitions, earnout payments related to acquisitions and general corporate purposes.

On March 2, 2023, we closed and funded an offering of $950.0 million of unsecured senior notes in two tranches. The $350.0 million aggregate principal amount of 5.50% Senior Notes is due 2033 and $600.0 million aggregate principal amount of 5.75% Senior Notes is due 2053. The weighted average interest rate is 5.05% per annum after giving effect to underwriting costs and a net hedge gain. During 2019 through 2022, we entered into a pre‑issuance interest rate hedging transaction related to these notes. We realized a net cash gain of approximately $112.7 million on the hedging transactions that will be recognized on a pro rata basis as a decrease to our reported interest expense over ten years. We used the proceeds of these offerings to fund acquisitions, earnout payments related to acquisitions and general corporate purposes.

Note Purchase Agreements - During February 2024, we used operating cash to fund the $100.0 million Series HH note maturity that had a fixed rate of 4.72% that was due February 13, 2024 and the $325.0 million Series H note maturity that had a fixed rate of 4.58% that was due February 27, 2024.

During June 2023, we used operating cash to fund the $200.0 million Series N note maturity that had a fixed rate of 4.13% that was due June 24, 2023 and the prepayment of the $50.0 million Series CC note floating rate of 90 day LIBOR plus 1.40%, balloon that was originally due on June 13, 2024.

During February 2023, we used operating cash to fund the $50.0 million Series E note maturity that had a fixed rate of 5.49% that was due February 10, 2023.

Under the terms of the note purchase agreements described above, we may redeem the notes at any time, in whole or in part, at 100% of the principal amount of such notes being redeemed, together with accrued and unpaid interest and a “make-whole amount”. The “make-whole amount” is derived from a net present value computation of the remaining scheduled payments of principal and interest using a discount rate based on the U.S. Treasury yield plus 0.5% and is designed to compensate the purchasers of the notes for their investment risk in the event prevailing interest rates at the time of prepayment are less favorable than the interest rates under the notes. We do not currently intend to prepay any of the notes.

The note purchase agreements described above contain customary provisions for transactions of this type, including representations and warranties regarding us and our subsidiaries and various financial covenants, including covenants that require us to maintain specified financial ratios. We were in compliance with these covenants as of December 31, 2024. The note purchase agreements also provide customary events of default, generally with corresponding grace periods, including, without limitation, payment defaults with respect to the notes, covenant defaults, cross-defaults to other agreements evidencing

our or our subsidiaries’ indebtedness, certain judgments against us or our subsidiaries and events of bankruptcy involving us or our material subsidiaries.

The notes issued under the note purchase agreement are senior unsecured obligations of ours and rank equal in right of payment with our Credit Agreement discussed below.

Credit Agreement - On June 22, 2023, we entered into a new Credit agreement (which we refer to as the Credit Agreement) with an administrative agent and a group of other lenders. The Credit Agreement provides for a five-year unsecured revolving credit facility in the amount of $1,200.0 million (including a $75.0 million letter of credit sub-facility), which is also available in Pounds Sterling, Canadian Dollars, Australian Dollars, New Zealand Dollars, Euros, Japanese Yen and any other currencies agreed by the lenders. On November 7, 2023, we entered into the First Amendment to the Credit Agreement, pursuant to which we increased the commitments under the Credit Agreement to $1,700.0 million. The Credit Agreement permits us to designate wholly-owned subsidiaries located in certain jurisdictions as additional borrowers, the obligations of which under the Credit Agreement will be guaranteed by the Company, subject to the terms and conditions set forth in the Credit Agreement. Any subsidiary that guarantees any notes under the Company’s existing note purchase agreements is required to guarantee the obligations under the Credit Agreement. There are currently no subsidiary borrowers or guarantors under the Credit Agreement.

Loans borrowed under the Credit Agreement bear interest at a variable annual rate based on a customary benchmark rate for each available currency including Secured Overnight Financing Rate (which we refer to as SOFR) for loans in U.S. Dollars, or at our election solely for loans in U.S. Dollars, the base rate, plus in each case an applicable margin. Interest rates on base rate loans and outstanding drawings on letters of credit under the Credit Agreement will be based on the Base Rate, as defined in the Credit Agreement, plus a margin of 0.00% to 0.375%, depending on the rating of our long-term senior unsecured debt. Interest rates for SOFR loans and loans in currencies other than U.S. dollars under the Credit Agreement will be based on, as applicable, a SOFR Daily Floating Rate, Term SOFR, Alternative Currency Daily Rate or Alternative Currency Term Rate, as defined in the Credit Agreement, plus a margin of 0.775% to 1.375%, depending on the rating of our long-term senior unsecured debt. The annual facility fee related to the Credit Agreement is between 0.100% and 0.250% of the revolving credit commitment, depending on the rating of our long-term senior unsecured debt. Subject to certain conditions stated in the Credit Agreement, we may borrow, prepay and reborrow amounts under the Credit Agreement at any time during the term of the Credit Agreement. Funds borrowed under the Credit Agreement may be used for general corporate and working capital purposes of the Company and its subsidiaries.

The Credit Agreement also contains customary representations and warranties and affirmative and negative covenants, including financial covenants, as well as customary events of default, with corresponding grace periods, including without limitations, payment defaults, cross‑defaults to other agreements evidencing indebtedness and bankruptcy-related defaults. We were in compliance with these covenants as of December 31, 2024.

Concurrently, on June 22, 2023, we paid off and terminated all of our obligations under the Second Amended and Restated Multicurrency Credit Agreement, dated as of June 7, 2019.

At December 31, 2024, $10.9 million of letters of credit (for which we had $12.0 million of liabilities recorded at December 31, 2024) were outstanding under the Credit Agreement. See Note 15 to these consolidated financial statements for a discussion of the letters of credit. There were no borrowings outstanding under the Credit Agreement at December 31, 2024. Accordingly, at December 31, 2024, $1,689.1 million remained available for potential borrowings.

Premium Financing Debt Facility - On October 30, 2024, we entered into an amendment to our revolving loan facility (which we refer to as the Premium Financing Debt Facility), that provides funding for the three Australian (AU) and New Zealand (NZ) premium finance subsidiaries. The Premium Financing Debt Facility is comprised of: (i) Facility B is separated into AU$410.0 million and NZ$25.0 million tranches (the AU$ tranche has been decreased as of February 1, 2025 to AU$390.0 million and the NZ$ tranche will be decreased as of May 1, 2025 to NZ$10.0 million), (ii) Facility C, an AU$60.0 million equivalent multi-currency overdraft tranche and (iii) Facility D, a NZ$15.0 million equivalent multi-currency overdraft tranche.

The interest rates on Facility B are Interbank rates, which vary by tranche, duration and currency, plus a margin of 1.400% and 1.850% for the AU$ and NZ$ tranches, respectively. The interest rates on Facilities C and D are 30 day Interbank rates, plus a margin of 0.830% and 0.990% for the AU$ and NZ$ tranches, respectively. The annual fee for Facility B is 0.56% and 0.8325% for the undrawn commitments for the AU$ and NZ$ tranches, respectively. The annual fee for Facility C is 0.77% and for Facility D is 0.90% of the total commitments of the facilities.

The terms of our Premium Financing Debt Facility include various financial covenants, including covenants that require us to maintain specified financial ratios. We were in compliance with these covenants as of December 31, 2024. The Premium Financing Debt Facility also includes customary provisions for transactions of this type, including events of default, with corresponding grace periods and cross-defaults to other agreements evidencing our indebtedness. Facilities B, C and D are secured by the premium finance receivables of the Australian and New Zealand premium finance subsidiaries.

 

At December 31, 2024, AU$350.0 million and NZ$0.0 million of borrowings were outstanding under Facility B, AU$0.0 million of borrowings outstanding under Facility C and NZ$12.5 million of borrowings were outstanding under Facility D, which in aggregate amount to US$225.2 million of borrowings outstanding under the Premium Financing Debt Facility. Accordingly, as of December 31, 2024, AU$60.0 million and NZ$25.0 million remained available for potential borrowing under Facility B, and AU$60.0 million and NZ$2.5 million under Facilities C and D, respectively.

See Note 15 to these consolidated financial statements for additional discussion on our contractual obligations and commitments as of December 31, 2024.

The aggregate estimated fair value of the $13,073.0 million in debt under our various senior notes and note purchase agreements at December 31, 2024 was $12,072.7 million due to the long-term duration and fixed interest rates associated with these debt obligations. No active or observable market exists for our private long-term debt. Therefore, the estimated fair value of this debt is based on the income valuation approach, which is a valuation technique that converts future amounts (for example, cash flows or income and expenses) to a single current (that is, discounted) amount. The fair value measurement is determined on the basis of the value indicated by current market expectations about those future amounts. Because our debt issuances generate a measurable income stream for each lender, the income approach was deemed to be an appropriate methodology for valuing the private placement long‑term debt. The methodology used calculated the original deal spread at the time of each debt issuance, which was equal to the difference between the yield of each issuance (the coupon rate) and the equivalent benchmark treasury yield at that time. The market spread as of the valuation date was calculated, which is equal to the difference between an index for investment grade insurers and the equivalent benchmark treasury yield today. An implied premium or discount to the par value of each debt issuance based on the difference between the origination deal spread and market as of the valuation date was then calculated. The index we relied on to represent investment graded insurers was the Bloomberg Valuation Services (BVAL) U.S. Insurers BBB index. This index is comprised primarily of insurance brokerage firms and was representative of the industry in which we operate. For the purpose of our analysis, the average BBB rate was assumed to be the appropriate borrowing rate for us. The estimated fair value of the borrowings outstanding under our Credit Agreement approximate their carrying value due to their short-term duration and variable interest rates. The estimated fair value of the $225.2 million of borrowings outstanding under our Premium Financing Debt Facility approximates their carrying value due to their short-term duration and variable interest rates.

Anti-dilutive stock-based awards of 0.9 million, 0.9 million and 2.0 million shares were outstanding at December 31, 2024, 2023 and 2022, respectively, but were excluded in the computation of the dilutive effect of stock‑based awards for the year then ended. These stock-based awards were excluded from the computation because the exercise prices on these stock-based awards were greater than the average market price of our common shares during the respective period, and therefore, would be anti‑dilutive to earnings per share under the treasury stock method.

Stock Option Plans

9. Stock Option Plans

On May 10, 2022, our stockholders approved the Arthur J. Gallagher & Co. 2022 Long-Term Incentive Plan (which we refer to as the LTIP), which replaced our previous stockholder-approved Arthur J. Gallagher & Co. 2017 Long-Term Incentive Plan (which we refer to as the 2017 LTIP). The LTIP term began May 10, 2022 and terminates on the date of the annual meeting of stockholders in 2032, unless terminated earlier by our board of directors. All of our officers, employees and non-employee directors are eligible to receive awards under the LTIP. The compensation committee of our board of directors determines the annual number of shares delivered under the LTIP. The LTIP provides for non-qualified and incentive stock options, stock appreciation rights, restricted stock and restricted stock units, any or all of which may be made contingent upon the achievement of performance criteria.

Shares of our common stock available for issuance under the LTIP include authorized and unissued shares of common stock or authorized and issued shares of common stock reacquired and held as treasury shares or otherwise, or a combination thereof. The number of available shares will be reduced by the aggregate number of shares that become subject to outstanding awards granted under the LTIP. A maximum of 3.5 million shares issued for full value awards (i.e., awards other than stock options or stock appreciation rights) will be counted one-for-one against the 13.5 million share pool, and every share subject to a full value award in excess of such limit count as 3.8 shares against the pool. To the extent that shares subject to an outstanding award granted under either the LTIP or prior equity plans are not issued or delivered by reason of the expiration, termination, cancellation or forfeiture of such award or by reason of the settlement of such award in cash, then such shares will again be available for grant under the LTIP.

The maximum number of shares available under the LTIP for restricted stock, restricted stock unit awards and performance unit awards settled with stock (i.e., all awards other than stock options and stock appreciation rights) is 2.5 million as of December 31, 2024.

The LTIP provides for the grant of stock options, which may be either tax-qualified incentive stock options or non-qualified options and stock appreciation rights. The compensation committee determines the period for the exercise of a non-qualified stock option, tax-qualified incentive stock option or stock appreciation right, provided that no option can be exercised later than seven years after its date of grant. The exercise price of a non-qualified stock option or tax-qualified incentive stock option and the base price of a stock appreciation right cannot be less than 100% of the fair market value of a share of our common stock on the date of grant, provided that the base price of a stock appreciation right granted in tandem with an option will be the exercise price of the related option.

Upon exercise, the option exercise price may be paid in cash, by the delivery of previously owned shares of our common stock, through a net-exercise arrangement, or through a broker-assisted cashless exercise arrangement. The compensation committee determines all of the terms relating to the exercise, cancellation or other disposition of an option or stock appreciation right upon a termination of employment, whether by reason of disability, retirement, death or any other reason. Stock option and stock appreciation right awards under the LTIP are non-transferable.

On March 1, 2024, the compensation committee granted 1,044,000 options under the LTIP to our officers and key employees that become exercisable at the rate of 34%, 33% and 33% on the anniversary date of the grant in 2027, 2028 and 2029, respectively. On March 15, 2023, the compensation committee granted 1,131,000 options under the LTIP to our officers and key employees that become exercisable at the rate of 34%, 33% and 33% on the anniversary date of the grant in 2026, 2027 and 2028, respectively. On February 1, 2022 and March 15, 2022, the compensation committee granted 1,197,000 and 1,141,000 options, respectively, under the 2017 LTIP to our officers and key employees that become exercisable at the rate of 34%, 33% and 33% on the anniversary date of the grant in 2025, 2026, and 2027, respectively.

The 2024, 2023 and 2022 options expire seven years from the date of grant, or earlier in the event of certain terminations of employment. Stock options granted in 2023 and 2022 to certain executive officers age 55 or older are not subject to forfeiture upon such officers’ departure from the Company after two years from date of grant. Stock options granted in 2024 to executive officers are not subject to forfeiture upon such officers’ departure from the Company once they attain the age of 62.

Our stock option plans provide for the immediate vesting of all outstanding stock option grants in the event of a change in control of the Company, as defined in the applicable plan documents.

During 2024, 2023 and 2022, we recognized $47.8 million, $33.5 million, and $27.9 million, respectively, of compensation expense related to our stock option grants.

For purposes of expense recognition in 2024, 2023 and 2022, the estimated fair values of the stock option grants are amortized to expense over the options’ vesting period. We estimated the fair value of stock options at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:

Option valuation models require the input of highly subjective assumptions including the expected stock price volatility. The Black‑Scholes option pricing model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. The weighted average fair value per option for all options granted during 2024, 2023 and 2022, as determined on the grant date using the Black-Scholes option pricing model, was $69.55, $46.48 and $33.25, respectively.

Options with respect to 11.1 million shares (less any shares of restricted stock issued under the LTIP - see Note 11 to these consolidated financial statements) were available for grant under the LTIP at December 31, 2024.

The total intrinsic value of options exercised during 2024, 2023 and 2022 amounted to $243.7 million, $181.6 million and $168.2 million, respectively. As of December 31, 2024, we had approximately $123.8 million of total unrecognized compensation expense related to nonvested options. We expect to recognize that cost over a weighted average period of approximately four years.

Deferred Compensation

10. Deferred Compensation

We have a Deferred Equity Participation Plan, (which we refer to as the DEPP), which is a non-qualified plan that generally provides for distributions to certain of our key executives when they reach age 62 (or the one-year anniversary of the date of the grant for participants over the age of 61 as of the grant date) or upon or after their actual retirement if later. Under the provisions of the DEPP, we typically contribute cash in an amount approved by the compensation committee to a rabbi trust on behalf of the executives participating in the DEPP, and instruct the trustee to acquire a specified number of shares of our common stock on the open market or in privately negotiated transactions based on participant elections. Distributions under the DEPP may not normally be made until the participant reaches age 62 (or the one-year anniversary of the date of the grant for participants over the age of 61 as of the grant date) and are subject to forfeiture in the event of voluntary termination of employment or termination for cause prior to then. DEPP awards are generally made annually in the first quarter. In addition, we annually make awards under sub-plans of the DEPP for certain production staff, which generally provide for vesting and/or distributions no sooner than five years from the date of awards, although certain awards vest and/or distribute after the earlier of fifteen years or the participant reaching age 65. All contributions to the plan (including sub-plans) deemed to be invested in shares of our common stock are distributed in the form of our common stock and all other distributions are paid in cash.

Our common stock that is issued to or purchased by the rabbi trust as a contribution under the DEPP is valued at historical cost, which equals its fair market value at the date of grant or date of purchase. When common stock is issued, we record an unearned deferred compensation obligation as a reduction of capital in excess of par value in the accompanying consolidated balance sheet, which is amortized to compensation expense ratably over the vesting period of the participants. Future changes in the fair market value of our common stock owed to the participants do not have any impact on the amounts recorded in our consolidated financial statements.

In the first quarter of 2024, 2023 and 2022, the compensation committee approved $23.2 million, $25.1 million and $26.3 million, respectively, of awards in the aggregate to certain key executives under the DEPP that were contributed to the rabbi trust in the first quarters of 2024, 2023 and 2022, respectively. We contributed cash to the rabbi trust and instructed the trustee to acquire a specified number of shares of our common stock on the open market to fund these 2024, 2023 and 2022 awards. During 2024, 2023 and 2022, we charged $20.9 million, $21.7 million and $18.5 million, respectively, to compensation expense related to these awards.

In 2024, 2023 and 2022, the compensation committee approved $2.3 million, $3.0 million and $1.9 million, respectively, of awards under the sub‑plans referred to above, which were contributed to the rabbi trust in first quarter 2024, 2023 and 2022, respectively. During 2024, 2023 and 2022, we charged $2.1 million, $2.6 million and $2.3 million, respectively, to compensation expense related to these awards. There were $3.0 million and $13.8 million of distributions from the sub-plans during 2024 and 2023. There were no distributions from the sub‑plans during 2022.

At December 31, 2024 and 2023, we recorded $77.0 million (related to 2.2 million shares) and $81.1 million (related to 2.2 million shares), respectively, of unearned deferred compensation as a reduction of capital in excess of par value in the accompanying consolidated balance sheet. The total intrinsic value of our unvested equity based awards under the plan at December 31, 2024 and 2023 was $616.4 million and $504.9 million, respectively. During 2024, 2023 and 2022, cash and equity awards with an aggregate fair value of $40.4 million, $78.1 million and $45.6 million, respectively, were vested and distributed to executives under the DEPP.

We have a Deferred Cash Participation Plan (which we refer to as the DCPP), which is a non-qualified deferred compensation plan for certain key employees, other than executive officers, that generally provides for vesting and/or distributions no sooner than five years from the date of awards. Under the provisions of the DCPP, we typically contribute cash in an amount approved by the compensation committee to the rabbi trust on behalf of the executives participating in the DCPP, and instruct the trustee to acquire a specified number of shares of our common stock on the open market or in privately negotiated transactions based on participant elections. In the first quarter of each of 2024, 2023 and 2022, the compensation committee approved $8.1 million, $9.8 million and $8.3 million, respectively, of awards in the aggregate to certain key executives under the DCPP that were contributed to the rabbi trust in second quarters of 2024, 2023 and 2022, respectively. During 2024, 2023 and 2022 we charged $19.3 million, $17.3 million and $13.4 million to compensation expense related to these awards. There were $43.8 million, $23.2 million and $16.9 million of distributions from the DCPP during 2024, 2023 and 2022, respectively.

11. Restricted Stock, Performance Share and Cash Awards

Restricted Stock Awards

As discussed in Note 9 to these consolidated financial statements, on May 10, 2022, our stockholders approved the LTIP, which replaced our previous stockholder-approved 2017 LTIP. The LTIP provides for the grant of a stock award either as restricted stock or as restricted stock units to officers, employees and non-employee directors. In either case, the compensation committee may determine that the award will be subject to the attainment of performance measures over an established performance period. Stock awards and the related dividend equivalents are non-transferable and subject to forfeiture if the holder does not remain continuously employed with us during the applicable restriction period or, in the case of a performance-based award, if applicable performance measures are not attained. The compensation committee will determine all of the terms relating to the satisfaction of performance measures and the termination of a restriction period, or the forfeiture and cancellation of a restricted stock award upon a termination of employment, whether by reason of disability, retirement, death or any other reason.

The agreements awarding restricted stock units under the LTIP will specify whether such awards may be settled in shares of our common stock, cash or a combination of shares and cash and whether the holder will be entitled to receive dividend equivalents, on a current or deferred basis, with respect to such award. Prior to the settlement of a restricted stock unit, the holder of a restricted stock unit will have no rights as a stockholder of the Company. The maximum number of shares available under the LTIP for restricted stock, restricted stock units and performance unit awards settled with stock (i.e., all awards other than stock options and stock appreciation rights) is 4.0 million. At December 31, 2024, 2.5 million shares were available for grant under the LTIP for such awards.

In 2024, 2023 and 2022, we granted 355,245, 396,913 and 650,355 restricted stock units, respectively, to employees under the LTIP and 2017 LTIP, with an aggregate fair value of $85.1 million, $67.0 million and $99.4 million, respectively, at the date of grant.

These 2024, 2023 and 2022 restricted stock units vest as follows: 344,600 units granted in first quarter 2024, 800 units granted in second quarter 2024, 700 units in third quarter 2024, 2,300 units in fourth quarter 2024, 390,000 units granted in first quarter 2023, and 641,000 units granted in first quarter 2022 vest in full based on continued employment through March 1, 2029, March 15, 2028 and March 15, 2027, respectively, while the other 2024, 2023 and 2022 restricted stock unit awards generally vest in full based on continued employment through the vesting period on the anniversary date of the grant. For our executive officers age 55 or older, restricted stock units awarded in 2024, 2023 and 2022 are not subject to forfeiture upon such officers’ departure from the Company after two years from the date of grant.

The vesting periods of the 2024, 2023 and 2022 restricted stock unit awards are as follows (in actual shares):

We account for restricted stock awards at historical cost, which equals its fair market value at the date of grant, which is amortized to compensation expense ratably over the vesting period of the participants. Future changes in the fair market value of our common stock that is owed to the participants do not have any impact on the amounts recorded in our consolidated financial statements. During 2024, 2023 and 2022, we charged $53.8 million, $43.4 million and $36.4 million, respectively, to compensation expense related to restricted stock awards granted in 2017 through 2023. The total intrinsic value of unvested restricted stock at December 31, 2024 and 2023 was $548.9 million and $468.5 million, respectively. During 2024 and 2023, equity awards (including accrued dividends) with an aggregate fair value of $93.5 million and $62.2 million were vested and distributed to employees under this plan.

Performance Share Awards

On March 1, 2024, March 15, 2023 and March 15, 2022, pursuant to the LTIP, the compensation committee approved 58,000, 58,000 and 54,000, respectively of provisional performance share awards, with an aggregate fair value of $14.2 million, $10.3 million and $8.6 million, respectively, for future grants to our officers. Each performance share award was equivalent to the value of one share of our common stock on the date such provisional award was approved. At the end of the performance period, eligible participants will receive a number of earned shares based on the growth in adjusted EBITDAC per share (as defined in our 2024 Proxy Statement). Earned shares for the 2024, 2023 and 2022 provisional awards will fully vest based on continuous employment through March 1, 2027, March 15, 2026 and March 15, 2025, respectively, and will be settled in unrestricted shares of our common stock on a one‑for‑one basis as soon as practicable thereafter. The 2024, 2023 and 2022 awards are subject to a three-year performance period that began on January 1, 2024, 2023 and 2022, respectively, and vest on the three-year anniversary of the date of grant (March 1, 2027, March 15, 2026 and March 15, 2025). Performance share awards granted in 2023 and 2022 to certain executive officers age 55 or older, are not subject to forfeiture upon such officers’ departure from the Company after two years from the date of grant. Performance share awards granted in 2024 to executive officers are not subject to forfeiture upon such officers’ departure from the Company once they attain the age of 62. In each case, the awards vest on a pro rata basis based on the number of months rounded up during which the officer was employed during the three-year performance period. During 2024, 2023 and 2022, we recognized $22.0 million, $20.0 million and $15.2 million, respectively, to compensation expense related to performance share awards granted in 2020 through 2024. The total intrinsic value of unvested performance share awards at December 31, 2024 and 2023 was $93.0 million and $75.2 million. During 2024, 2023 and 2022, equity awards (including accrued dividends) with an aggregate fair value of $31.6 million, $28.9 million and $21.8 million were vested and distributed to employees under this plan.

Cash Awards

Pursuant to our Performance Unit Program (which we refer to as the Program), there were no units granted in 2024 and 2023. The Program consists of a one-year performance period based on our financial performance and a three-year vesting period measured from January 1 of the year of grant. At the discretion of the compensation committee and determined based on our performance, the eligible officer or key employee will be granted a percentage of the provisional cash award units that equates to the EBITDAC growth achieved (as defined in the Program). At the end of the performance period, eligible participants will be granted a number of units based on achievement of the performance goal and subject to approval by the compensation committee. Granted units will fully vest based on continuous employment through the three-year vesting period. The ultimate award value will be equal to the trailing twelve‑month price of our common stock, multiplied by the number of units subject to the award, but limited to between 0.5 and 1.5 times the original value of the units determined as of the grant date. The fair value of the awarded units will be paid out in cash as soon as practicable. If an eligible employee leaves us prior to the vesting date, the entire award will be forfeited.

On March 15, 2022, pursuant to the Program, the compensation committee approved provisional cash awards of $19.9 million in the aggregate for future grants to our officers and key employees that are denominated in units (125,000 units in the aggregate), each of which was equivalent to the value of one share of our common stock on the date the provisional award was approved. Based on our performance for 2022, we granted 122,000 units under the Program in first quarter of 2023 that fully vested on

January 1, 2025. During 2024 and 2023 we charged $13.2 million and $13.4 million to compensation expense related to these awards. We did not recognize any compensation expense during 2022 related to the 2022 provisional award under the Program.

On March 16, 2021, pursuant to the Program, the compensation committee approved provisional cash awards of $18.8 million in the aggregate for future grants to our officers and key employees that are denominated in units (147,000 units in the aggregate), each of which was equivalent to the value of one share of our common stock on the date the provisional award was approved. Based on our performance for 2021, we granted 143,000 units under the Program in the first quarter of 2022 that fully vested on January 1, 2024. During 2023 and 2022 we charged $13.1 million and $12.4 million, respectively, to compensation expense related to these awards. We did not recognize any compensation expense during 2021 related to the 2021 provisional award under the Program.

During 2024, cash awards related to the 2021 provisional awards with an aggregate fair value of $25.4 million (129,000 units in the aggregate) were vested and distributed to employees under the Program. During 2023, cash awards related to the 2020 provisional awards with an aggregate fair value of $24.7 million (191,000 units in the aggregate) were vested and distributed to employees under the Program. During 2022, cash awards related to the 2019 provisional awards with an aggregate fair value of $21.1 million (177,000 units in the aggregate) were vested and distributed to employees under the Program.

12. Retirement Plans

We have a noncontributory defined benefit pension plan that, prior to July 1, 2005, covered substantially all of our domestic employees who had attained a specified age and one year of employment. Benefits under the plan were based on years of service and salary history. In 2005, we amended our defined benefit pension plan to freeze the accrual of future benefits for all U.S. employees, effective on July 1, 2005. Since the plan is frozen, there is no difference between the projected benefit obligation and accumulated benefit obligation at December 31, 2024 and 2023.

Through the acquisition of the partnership interests of BCHR holdings, L.P. and its subsidiaries dba Buck (which we refer to as Buck), we acquired the assets and assumed the liabilities associated with three frozen defined benefit pension plans that provide postretirement benefits to their participants located in the U.S., U.K. and Canada (which we refer to as the Buck Pension Plans). The Buck Pension Plans were amended to freeze benefit plan accruals for all participants (closed to new entrants and existing participants do not accrue any additional benefits) effective December 31, 2014. Effective December 31, 2024, the U.S. Buck Pension Plan was merged into our defined benefit pension plan.

In January 2025, we notified plan participates that we will fully terminate such plan. In first quarter 2025, we will initiate the wind down of the plan and we expect to complete such wind down by settling all future obligations under the plan through a combination of lump sum payments to eligible, electing participants and transferring the remaining liability through the purchase of a group annuity contract to a highly-rated third-party insurance company. We expect that the wind down will be completed in fourth quarter 2025. Based on estimates as of December 31, 2024, we anticipate recognizing a non-cash, pre-tax loss of approximately $34.2 million in fourth quarter 2025 to compensation expense in the consolidated statement of earnings that may be offset by an approximately $12.8 million adjustment to consolidated statement of comprehensive earnings, a $16.5 million write‑down of a prepaid pension asset and a $4.6 million reversal of a deferred tax asset.

Plan assets are invested in various pooled separate accounts under annuity contracts managed by two life underwriting enterprises. The plan’s investment policy provides that investments will be allocated in a manner designed to provide a long‑term investment return greater than the actuarial assumptions, maximize investment return commensurate with risk and to comply with the Employee Income Retirement Security Act of 1974, as amended (which we refer to as ERISA), by investing the funds in a manner consistent with ERISA’s fiduciary standards. The weighted average expected long-term rate of return on plan assets assumption was determined based on a review of the asset allocation strategy of the plan using expected ten-year return assumptions for all of the asset classes in which the plan was invested at December 31, 2024 and 2023. The return assumptions used in the valuation were based on data provided by the plan’s external investment advisors.

The plan’s Level 2 assets consist of ownership interests in various pooled separate accounts within a life insurance carrier’s group annuity contract. The fair value of the pooled separate accounts is determined based on the net asset value of the respective funds, which is obtained from the underwriting enterprise and determined each business day with issuances and redemptions of units of the funds made based on the net asset value per unit as determined on the valuation date. We have not adjusted the net asset values provided by the underwriting enterprise. There are no restrictions as to the plan’s ability to redeem its investment at the net asset value of the respective funds as of the reporting date. The plan’s Level 3 assets consist of pooled separate accounts within another life insurance carrier’s annuity contracts for which fair value has been determined by an independent valuation. Due to the nature of these annuity contracts, our management makes assumptions to determine how a market participant would price these Level 3 assets. In determining fair value, the future cash flows to be generated by the annuity contracts were estimated using the underlying benefit provisions specified in each contract, market participant

assumptions and various actuarial and financial models. These cash flows were then discounted to present value using a risk-adjusted rate that takes into consideration market based rates of return and probability-weighted present values.

We were not required under the IRC to make any minimum contributions to the plan for each of the 2024, 2023 and 2022 plan years. This level of required funding is based on the plan being frozen and the aggregate amount of our historical funding. During 2024, 2023 and 2022 we did not make discretionary contributions to the plan.

We comply with the minimum funding requirements in the U.S., U.K. and Canada and will make annual contributions to the Buck Pension Plans consistent with those funding requirements. We recognize the funded status of the Buck Pension Plans, measured as the difference between the fair value of the plan assets and the projected benefit obligation, in the accompanying December 31, 2024 and 2023 consolidated balance sheets. As of December 31, 2023, the funded/(unfunded) status related to the Buck Pension Plans was $(21.6) million in the U.S., $10.8 million in the U.K. and $(1.3) million in Canada and have been recorded in other noncurrent assets and liabilities.

We also have a qualified contributory savings and thrift 401(k) plan covering the majority of our domestic employees. For eligible employees who have met the plan’s age and service requirements to receive matching contributions, we historically have matched 100% of pre-tax and Roth elective deferrals up to a maximum of 5.0% of eligible compensation, subject to federal limits on plan contributions and not in excess of the maximum amount deductible for federal income tax purposes. Beginning in 2021, the amount matched by the Company will be discretionary and annually determined by management. Employees must be employed and eligible for the plan on the last day of the plan year to receive a matching contribution, subject to certain exceptions enumerated in the plan document. Matching contributions are subject to a five-year graduated vesting schedule and can be funded in cash or common stock of the Company. We expensed (net of plan forfeitures) $105.4 million, $86.0 million and $73.8 million related to the plan in 2024, 2023 and 2022 respectively. During 2022 and 2023, management determined the 5.0% employer matching contributions on eligible compensation to the 401(k) plan for the 2022 and 2023 plan years to be funded with our common stock, which were funded in February 2023 and 2024, respectively. During 2024, management determined the 5.0% employer matching contributions on eligible compensation to the 401(k) plan for the 2024 plan year would be funded with our common stock, which is expected to be funded in February 2025.

We also have a nonqualified deferred compensation plan, the Supplemental Savings and Thrift Plan, for certain employees who, due to IRS rules, cannot take full advantage of our matching contributions under the 401(k) plan. The plan permits these employees to annually elect to defer a portion of their compensation until their retirement or a future date. Our matching contributions to this plan (up to a maximum of the lesser of a participant’s elective deferral of base salary, annual bonus and commissions or 5.0% of eligible compensation, less matching amounts contributed under the 401(k) plan) are also discretionary and annually determined by management. Matching contributions can be funded in cash or common stock of the Company. We expensed $14.3 million, $12.3 million and $11.0 million related to contributions made to a rabbi trust maintained under the plan in 2024, 2023 and 2022, respectively. During 2024, management determined the 5.0% employer matching contributions on eligible compensation to the plan for the 2024 plan year would be funded with our common stock, which is expected to be funded in February 2025. The fair value of the assets in the plan’s rabbi trust at December 31, 2024 and 2023, including employee contributions and investment earnings, was $909.1 million and $728.4 million, respectively, and has been included in other noncurrent assets and the corresponding liability has been included in other noncurrent liabilities in the accompanying consolidated balance sheet.

We also have several foreign benefit plans, the largest of which is a defined contribution plan that provides for us to make contributions of 5.0% of eligible compensation. In addition, the plan allows for voluntary contributions by U.K. employees, which we match 100%, up to a maximum of an additional 5.0% of eligible compensation. Net expense for foreign retirement plans amounted to $92.6 million, $76.7 million and $62.9 million in 2024, 2023 and 2022, respectively.

13. Leases

We have operating leases primarily related to branch facilities, data centers, sales offices, and agent locations, automobiles and office equipment. Many of our leases include both lease (fixed rent payments) and non-lease components (common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. Variable lease payments, such as periodically indexed and/or market adjustments, are presented as lease expense in the period in which they are incurred. Since we did not elect the short-term policy election, we record leases of 12 months or less on the balance sheet.

We exclude options to extend or terminate a lease from our recognition as part of our right-of-use assets and lease liabilities until those options are reasonably certain and/or executed. We do not have any material guarantees, options to purchase, or restrictive covenants related to our leases.

As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. We consider qualitative factors including our derived credit rating, notched adjustments for collateralization, lease term, and, if significant, adjustments to our collateralized rate to borrow in the same currency in which the lease is denominated.

Derivatives and Hedging Activity

14. Derivatives and Hedging Activity

We are exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, we enter into various derivative instruments that reduce these risks by creating offsetting exposures. We generally do not enter into derivative transactions for trading or speculative purposes.

Foreign Exchange Risk Management

We are exposed to foreign exchange risk when we earn revenues, pay expenses, or enter into monetary intercompany transfers denominated in a currency that differs from our functional currency, or other transactions that are denominated in a currency other than our functional currency. We use foreign exchange derivatives, typically forward contracts and options, to reduce our overall exposure to the effects of currency fluctuations on cash flows. These exposures are hedged, on average, for less than three years.

Interest Rate Risk Management

We enter into various long-term debt agreements. We use interest rate derivatives, typically swaps, to reduce our exposure to the effects of interest rate fluctuations on the forecasted interest rates for up to three years into the future.

We have not received or pledged any collateral related to derivative arrangements at December 31, 2024.

Included within foreign exchange contracts at December 31, 2024 were $595.4 million of call options offset with $595.4 million of put options, and $1.2 million of buy forwards offset with $25.6 million of sell forwards. Included within foreign exchange contracts at December 31, 2023 were $331.3 million of call options offset with $331.3 million of put options, and $5.5 million of buy forwards offset with $73.3 million of sell forwards.

 

Fair values of these hedge contracts are based on observable and unobservable inputs. Observable inputs include all of the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example: interest rates and yield curves observable at commonly quoted intervals, implied volatilities, credit spreads) and market-corroborated inputs. Unobservable inputs are used to measure fair value to the extent that relevant observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

The amounts presented in the table above may not necessarily reflect our actual future cash funding requirements, because the actual timing of the future payments made may vary from the stated contractual obligation.

Senior Notes, Note Purchase Agreements, Credit Agreement and Premium Financing Debt Facility - See Note 7 to these consolidated financial statements for a summary the amounts outstanding under the Senior Notes, Note purchase agreements, the Credit Agreement and Premium Financing Debt Facility.

Operating Lease Obligations - Our corporate segment’s executive offices and certain subsidiary and branch facilities of our brokerage and risk management segments are located in a building we own at 2850 Golf Road, Rolling Meadows, Illinois, where we have approximately 360,000 square feet of space and can accommodate approximately 2,000 employees. Relating to the development of our corporate headquarters, we expect to receive property tax related credits under a tax-increment financing note from Rolling Meadows and an Illinois state Economic Development for a Growing Economy (which we refer to as EDGE) tax credit. Incentives from these two programs could total between $50.0 million and $80.0 million over a fifteen‑year period. We have earned approximately $62.6 million of EDGE credits from inception in 2017 through December 31, 2024.

We generally operate in leased premises at our other locations. Certain of these leases have options permitting renewals for additional periods. In addition to minimum fixed rentals, a number of leases contain annual escalation clauses which are generally related to increases in an inflation index.

Total rent expense, including rent relating to cancelable leases and leases with initial terms of less than one year, amounted to $183.4 million in 2024, $183.5 million in 2023 and $176.6 million in 2022.

We have leased certain office space to several non-affiliated tenants under operating sublease arrangements. In the normal course of business, we expect that certain of these leases will not be renewed or replaced. We adjust charges for real estate taxes and common area maintenance annually based on actual expenses, and we recognize the related revenues in the year in which the expenses are incurred. These amounts are not included in the minimum future rentals to be received in the contractual obligations table above.

Outstanding Purchase Obligations - We typically do not have a material amount of outstanding purchase obligations at any point in time. The amount disclosed in the contractual obligations table above represents the aggregate amount of unrecorded purchase obligations that we had outstanding at December 31, 2024. These obligations represent agreements to purchase goods or services that were executed in the normal course of business.

Since commitments may expire unused, the amounts presented in the table above do not necessarily reflect our actual future cash funding requirements. See the Off-Balance Sheet Debt section below for a discussion of letters of credit. All of the letters of credit represent multiple year commitments that have annual, automatic renewing provisions and are classified by the latest commitment date.

Substantially all of the purchase agreements related to these acquisitions we do contain provisions for potential earnout obligations. For all of our acquisitions made in the period from 2021 to 2024 that contain potential earnout obligations, such obligations are measured at fair value as of the acquisition date and are included on that basis in the recorded purchase price consideration for the respective acquisition. The amounts recorded as earnout payables are primarily based upon estimated future potential operating results of the acquired entities over a two- to three-year period subsequent to the acquisition date. The aggregate amount of the maximum earnout obligations related to these acquisitions was $1,998.2 million, of which $1,302.0 million was recorded in our consolidated balance sheet as of December 31, 2024 based on the estimated fair value of the expected future payments to be made, of which approximately $511.9 million can be settled in cash or common stock at our option and $790.1 million must be settled in cash.

Off-Balance Sheet Debt - Our unconsolidated investment portfolio includes investments in enterprises where our ownership interest is between 1% and 50%, in which management has determined that our level of influence and economic interest is not sufficient to require consolidation. As a result, these investments are accounted for under the equity method. None of these unconsolidated investments had any outstanding debt at December 31, 2024 and 2023 that was recourse to us.

At December 31, 2024, we had posted two letters of credit totaling $9.2 million in the aggregate, related to our self-insurance deductibles, for which we had a recorded liability of $12.0 million. We have an equity investment in a rent-a-captive facility, which we use as a placement facility for certain of our insurance brokerage operations. At December 31, 2024, we had posted eight letters of credit totaling $13.0 million to allow certain of our captive operations to meet minimum statutory surplus requirements plus additional collateral related to premium and claim funds held in a fiduciary capacity and one letter of credit totaling $0.8 million for collateral related to claim funds held in a fiduciary capacity by a recent acquisition. These letters of credit have never been drawn upon.

The guarantees are collateralized by shares in minority holdings of our Canadian operating companies.

Since commitments may expire unused, the amounts presented in the table above do not necessarily reflect our actual future cash funding requirements.

Litigation, Regulatory and Taxation Matters - We routinely are involved in legal proceedings, claims, disputes, regulatory matters and governmental inspections or investigations arising in the ordinary course of or incidental to our business, including relating errors and omissions (which we refer to as E&O) claims and those noted below in this section. We record accruals in the consolidated financial statements for pending litigation when we determine that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. For the matters we disclose that do not include an estimate of the amount of loss or range of losses, such an estimate is not possible or is immaterial, and we may be unable to estimate the possible loss or range of losses that could potentially result from the application of non-monetary remedies, unless disclosed below. We currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not materially harm our financial position, results of operations or cash flows. However, legal proceedings and government investigations are subject to inherent uncertainties, and unfavorable rulings or other adverse events could occur, including the payment of substantial monetary damages or an injunction or other order prohibiting us from selling one or more products at all or in particular ways, precluding particular business practices or requiring other remedies, which may result in a material adverse impact on our business, results of operations or financial position.

As previously disclosed, our IRC 831(b) (or “micro-captive”) advisory services businesses has been under a promoter investigation by the IRS since 2013. Among other matters, the IRS is investigating whether we have been acting as a tax shelter promoter in connection with these operations. Additionally, the IRS is conducting a criminal investigation related to IRC 831(b)

micro-captive underwriting enterprises. We have been advised that we are not a target of the criminal investigation. We are fully cooperating with both matters.

Contingent Liabilities - We purchase insurance to provide protection from E&O claims that may arise during the ordinary course of business. Currently we retain the first $15.0 million of each and every E&O claim. In addition, we retain, in aggregate: up to another $2.0 million between $15.0 million and $100.0 million, plus up to another $10.0 million between $100.0 million and $225.0 million, and up to another $20.0 million between $225.0 million and $400.0 million. We have historically maintained self-insurance reserves for the portion of our E&O exposure that is not insured. We periodically determine a range of possible reserve levels using actuarial techniques that rely heavily on projecting historical claim data into the future. Our E&O reserve in the December 31, 2024 consolidated balance sheet is above the lower end of the most recently determined actuarial range by $4.4 million and below the upper end of the actuarial range by $10.7 million. We can make no assurances that the historical claim data used to project the current reserve levels will be indicative of future claim activity. Thus, the E&O reserve level and corresponding actuarial range could change in the future as more information becomes known, which could materially impact the amounts reported and disclosed herein.

The total amount of net unrecognized tax benefits that, if recognized, would affect the effective tax rate was $24.7 million and $24.5 million at December 31, 2024 and 2023, respectively. We accrue interest and penalties related to unrecognized tax benefits in our provision for income taxes. At December 31, 2024 and 2023, we had accrued interest and penalties related to unrecognized tax benefits of $10.3 million and $2.8 million, respectively.

We file income tax returns in the U.S. and in various state, local and foreign jurisdictions. We are routinely examined by tax authorities in these jurisdictions. At December 31, 2024, our corporate returns had been examined by the IRS or the statute had lapsed through calendar year 2020. In addition, from 2020 forward, various state and foreign jurisdictions remain open. It is reasonably possible that our gross unrecognized tax benefits may change within the next twelve months. However, we believe any changes in the recorded balance would not have a significant impact on our consolidated financial statements.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

At December 31, 2024 and 2023, $106.3 million and $129.6 million, respectively, of deferred tax liabilities have been included in noncurrent liabilities in the accompanying consolidated balance sheet. General business and other tax credits of $736.9 million begin to expire, if not utilized, in 2032 and state credits, net of federal benefit, of $32.0 million expire, if not used, by 2028. Net operating loss carryforwards of $162.7 million, related to federal, state and foreign begin to expire, if not utilized in 2025. We expect the historically favorable trend in earnings before income taxes to continue in the foreseeable future. Valuation allowances have been established for certain foreign intangible assets (including nondeductible amortization and earnout payable expenses) and various state net operating loss carryforwards that may not be utilized in the future.

At December 31, 2024, foreign earnings in all jurisdictions are considered indefinitely reinvested offshore. We have not provided for state or withholding income taxes on the undistributed earnings of $812.3 million and $632.3 million at December 31, 2024 and 2023, respectively, of foreign subsidiaries which are considered permanently invested outside of the U.S. The amount of unrecognized deferred tax liability on these undistributed earnings was not material at December 31, 2024 and 2023.

Current U.S. tax law requires U.S. shareholders to include in income certain “global intangible low-taxed income” (which we refer to as GILTI) beginning in 2018. Our policy is to include the GILTI income in the future period when the tax arises and we recorded income tax expense on such income in 2024, 2023 and 2022. Current U.S. tax law includes the U.S. Base Erosion and Anti-Abuse Tax (which we refer to as BEAT) beginning in 2018. Based on our analysis, we determined that our base erosion payments do not exceed the threshold for applicability for the years in 2024, 2023 and 2022, and we do not currently anticipate any significant long-term impact from the BEAT in our provision for income taxes in future periods.

The 2023 income taxes paid amount was favorably impacted due to the reversal of tax method changes on filing of the 2022 tax return. In 2022, we elected to defer the utilization of 2021 and 2022 net operating losses in the U.K. causing additional cash tax payments of $28.4 million relating to 2021 and $49.0 million relating to 2022. Both the U.S. and U.K. payments would have been made in future periods, and do not represent additional taxes due.

The following is a reconciliation of our end of period cash, cash equivalents, restricted cash and fiduciary cash balances as presented in the consolidated statement of cash flows for the years ended December 31, 2024, 2023 and 2022 (in millions):

Total cash and cash equivalents, restricted cash and fiduciary cash at December 31, 2024 and December 31, 2023, include $15,371.6 million and $1,744.9 million, respectively, of income earning money market accounts. The increase in cash invested in money market accounts between years is primarily due to the proceeds received in December 2024 from the stock issuance ($8.5 billion) and senior notes ($5.0 billion). Refer to Note 7 for more information regarding the senior notes. These proceeds are intended to be used toward the acquisition of AssuredPartners, refer to Note 3 for more information regarding this acquisition. The dividend income on money market accounts was recorded in interest income, premium finance and other income in our consolidated statement of earnings, which increased $105.9 million during 2024 ($29.0 million of which related to the proceeds from the AssuredPartners financing) to $473.2 million for the year ended December 31, 2024 compared to $367.3 million for the year ended December 31, 2023.

 

We have a qualified contributory savings and thrift 401(k) plan covering the majority of our domestic employees. For eligible employees who have met the plan’s age and service requirements to receive matching contributions, we historically have matched 100% of pre-tax and Roth elective deferrals up to a maximum of 5.0% of eligible compensation, subject to federal limits on plan contributions and not in excess of the maximum amount deductible for federal income tax purposes. Beginning in 2021, the amount matched by the Company will be discretionary and annually determined by management. Employees must be employed and eligible for the plan on the last day of the plan year to receive a matching contribution, subject to certain exceptions enumerated in the plan document. Matching contributions are subject to a five-year graduated vesting schedule and can be funded in cash or the common stock of the Company. We expensed (net of plan forfeitures) $105.4 million, $86.0 million and $73.8 million related to the plan in 2024, 2023 and 2022, respectively. During 2023, management determined the 5.0% employer matching contributions on eligible compensation to the 401(k) plan for the 2023 plan year to be funded with our common stock, which was funded in February 2024. During 2024, management determined the 5.0% employer matching contributions on eligible compensation to the 401(k) plan for the 2024 plan year to be funded with our common stock, which is expected to be funded in February 2025.

The foreign currency translation in 2024, 2023 and 2022 relates to the net impact of changes in the value of the local currencies relative to the U.S. dollar for our operations in Australia, Canada, the Caribbean, India, New Zealand, the U.K. and other non‑U.S. locations. The reporting currency for our financial statements is the U.S. dollar. Certain of our assets, liabilities, expenses and revenues are denominated in currencies other than the U.S. dollar, primarily the Australian dollar, British pound, Canadian dollar, and New Zealand dollar. To prepare our consolidated financial statements, we must translate those assets, liabilities, expenses and revenues into U.S. dollars at the applicable exchange rates. Assets and liabilities of non‑U.S. dollar functional currency operations are translated into U.S. dollars at end-of-period exchange rates while revenues, expenses and cash flows are translated at average monthly exchange rates over the period. Equity is translated at historical exchange rates and the resulting cumulative translation adjustments are included as a component of accumulated other comprehensive loss in the consolidated balance sheet. The net change in the foreign currency translation during 2024 primarily relates to goodwill (see Note 6 to these consolidated financial statements for the impact on goodwill) and amortizable intangible assets held by operations with a non‑U.S. dollar functional currency.

During 2024, 2023 and 2022, $2.2 million, $5.2 million and $2.2 million, respectively, of expense related to the pension liability was reclassified from accumulated other comprehensive loss to compensation expense in the statement of earnings. During 2024, 2023 and 2022, $6.8 million of expense, $3.1 million of expense and $3.2 million of income, respectively, related to the fair value of derivative investments, was reclassified from accumulated other comprehensive loss to the statement of earnings. During 2024, 2023 and 2022, no amounts related to foreign currency translation were reclassified from accumulated other comprehensive loss to the statement of earnings.

Segment Reporting [Abstract]  
Segment Information

19. Segment Information

We have three reportable segments: brokerage, risk management and corporate.

The brokerage segment is primarily comprised of our retail and wholesale insurance and reinsurance brokerage operations. The brokerage segment (which comprises our retail P/C, wholesale, reinsurance, benefits and captive operations) generates revenues through commissions paid by underwriting enterprises and through fees charged to our clients. Our brokers, agents and administrators act as intermediaries between underwriting enterprises and our clients and we do not assume net underwriting risks.

The risk management segment provides contract claim settlement and administration services for commercial, nonprofit, captive and public sector entities, and various organizations that choose to self-insure some or all of their property/casualty coverages and for underwriting enterprises that choose to outsource some or all of their property/casualty claims departments. These operations also provide claims management, loss control consulting and insurance property appraisal services. Revenues are principally generated on a negotiated per-claim or per-service fee basis. Our risk management segment also provides risk management consulting services that are recognized as the services are delivered.

Revenues in the corporate segment consist of other income related to the run-off of clean energy and legacy investments, and in 2024, some interest income related to the proceeds from the AssuredPartners financing. In addition, the corporate segment reports the financial information related to our debt, external acquisition-related expenses, other corporate costs and the impact of foreign currency remeasurement.

Allocations of investment income and certain expenses are based on reasonable assumptions and estimates primarily using revenue, headcount and other information. We allocate the provision for income taxes to the brokerage and risk management segments using the local country statutory rates. Reported operating results by segment would change if different methods were applied.

Our Chief Operating Decision Maker (which we refer to as CODM) (our Chairman and Chief Executive Officer) analyzes and evaluates the operating performance of the three reportable segments presented below. We have disclosed for each reportable segment the significant expense categories that are reviewed by the CODM and there are no additional significant expenses within the expense categories presented in the tables below. The key areas of focus by the CODM for allocation of resources are revenues from each reportable segment, as well as their compensation and operating expenses.

Financial information relating to our segments for 2024, 2023 and 2022 is as follows (in millions):

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]  
Nature of Operations

Nature of Operations

Arthur J. Gallagher & Co. and its subsidiaries, collectively referred to herein as we, our, us or the Company, provide insurance brokerage, consulting and third party claims settlement and administration services to both domestic and international entities. We have three reportable segments: brokerage, risk management and corporate. Our brokers, agents and administrators act as intermediaries between underwriting enterprises and our clients.

Our brokerage segment operations provide brokerage and consulting services to entities of all types, including commercial, nonprofit, public sector entities and to a lesser extent, individuals, in the areas of insurance and reinsurance placements, risk of loss management and management of employer sponsored benefit programs. Our risk management segment operations provide contract claim settlement, claim administration, loss control services and risk management consulting for commercial, nonprofit, captive and public sector entities, and various other organizations that choose to self-insure property/casualty coverages or choose to use a third-party claims management organization rather than the claim services provided by underwriting enterprises. The corporate segment reports the financial information related to our debt, external acquisition‑related expenses, other corporate costs and the impact of foreign currency translation. Legacy clean energy investments consist of our investments in limited liability companies that own or have owned 35 commercial clean coal production facilities that produced refined coal using Chem-Mod LLC’s proprietary technologies. We believe these operations produced refined coal that qualifies for tax credits under IRC Section 45.

We do not assume underwriting risk on a net basis, other than with respect to de minimis amounts necessary to provide minimum or regulatory capital insurance to organize captives, pools, specialized underwriters or risk-retention groups. Rather, capital necessary for covering losses is provided by underwriting enterprises.

Investment income and other revenues are primarily generated from our premium financing operations, our invested cash and restricted cash we hold on behalf of our clients, as well as clean energy investments. In addition, our share of the net earnings related to partially owned entities that are accounted for using the equity method is included in investment income.

Arthur J. Gallagher & Co., a global insurance brokerage, risk management and consulting services firm, is headquartered in Rolling Meadows, Illinois. The Company provides these services in approximately 130 countries around the world through its owned operations and a network of correspondent brokers and consultants.

Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements include our accounts and all of our majority-owned subsidiaries (50% or greater ownership). Substantially all of our investments in partially owned entities in which our ownership is less than 50% are accounted for using the equity method based on the legal form of our ownership interest and the applicable ownership percentage of the entity. However, in situations where a less than 50%-owned investment has been determined to be a variable interest entity and we are deemed to be the primary beneficiary in accordance with the variable interest model of consolidation, we will consolidate the investment into our consolidated financial statements. For partially owned entities accounted for using the equity method, our share of the net earnings of these entities is included in consolidated net earnings. All material intercompany accounts and transactions have been eliminated in consolidation.

In the preparation of our consolidated financial statements as of December 31, 2024, management evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date on which the financial statements were issued for potential recognition and/or disclosure in the notes therein.

Use of Estimates

Use of Estimates

The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These accounting principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses, and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements. We periodically evaluate our estimates and assumptions, including those relating to the valuation of goodwill and other intangible assets, right-of-use assets, investments, income taxes, revenue recognition, deferred costs, stock-based compensation, claims handling obligations, retirement plans, litigation and contingencies. We base our estimates on historical experience and various assumptions that we believe to be reasonable based on specific circumstances. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

Revenue Recognition

Revenue Recognition

Our revenues are derived from commissions and fees as primarily specified in a written contract, or unwritten business understanding, with our clients or underwriting enterprises. We also recognize investment income over time from our invested assets and invested assets we hold on behalf of our clients or underwriting enterprises.

Brokerage Segment

BROKERAGE SEGMENT

Our brokerage segment generates revenues by:

(i)
Identifying, negotiating and placing all forms of insurance coverage, as well as providing data analytics, risk-shifting, risk-sharing and risk-mitigation consulting services, principally related to property/casualty, life, health, welfare and disability insurance. We also provide these services through, or in conjunction with, other unrelated agents and brokers, consultants and management advisors;
(ii)
Identifying, negotiating and placing all forms of reinsurance coverage, as well as providing capital markets services, including acting as underwriter, with respect to insurance linked securities, weather derivatives, capital raising and selected merger and acquisition advisory activities;
(iii)
Acting as an agent or broker for multiple underwriting enterprises by providing services such as sales, marketing, selecting, negotiating, underwriting, servicing and placing insurance coverage on their behalf;
(iv)
Providing consulting services related to health and welfare benefits, voluntary benefits, executive benefits, compensation, retirement planning, institutional investment and fiduciary, actuarial, compliance, private insurance exchange, human resource technology, communications and benefits administration; and
(v)
Providing management and administrative services to captives, pools, risk-retention groups, healthcare exchanges, small underwriting enterprises, such as accounting, claims and loss processing assistance, feasibility studies, actuarial studies, data analytics and other administrative services.

The vast majority of our brokerage contracts and service understandings are for a period of one year or less.

Commissions and fees

The primary source of revenues for our brokerage services is commissions from underwriting enterprises, based on a percentage of premiums paid by our clients, or fees received from clients based on an agreed level of service usually in lieu of commissions. These commissions and fees revenues are substantially recognized at a point in time on the effective date of the associated policies when control of the policy transfers to the client, as well as deferring certain revenues to reflect delivery of services over the contract period.

Commissions are fixed at the contract effective date and generally are based on a percentage of premiums for insurance coverage or employee headcount for employer sponsored benefit plans. Commissions depend upon a large number of factors, including the type of risk being placed, the particular underwriting enterprise’s demand, the expected loss experience of the particular risk of coverage, and historical benchmarks surrounding the level of effort necessary for us to place and service the insurance contract. Rather than being tied to the amount of premiums, fees are most often based on an expected level of effort to provide our services.

Whether we are paid a commission or a fee, the vast majority of our services are associated with the placement of an insurance (or insurance-like) contract. Accordingly, we recognize approximately 85% of our commission and fee revenues on the effective date of the underlying insurance contract. The amount of revenue we recognize is based on our costs to provide our services up and through that effective date, including an appropriate estimate of our profit margin on a portfolio basis (a practical expedient as defined in Topic 606). Based on the proportion of additional services we provide in each period after the effective date of the insurance contract, including an appropriate estimate of our profit margin, we recognize approximately 10% of our commission and fee revenues in the first three months, and the remaining 5% thereafter. These periods may be different than the underlying premium payment patterns of the insurance contracts, but the vast majority of our services are fully provided within one year of the insurance contract effective date.

For consulting and advisory services, we recognize our revenue in the period in which we provide the service or advice. For management and administrative services, our revenue is recognized ratably over the contract period consistent with the performance of our obligations, mostly over an annual term.

Supplemental revenues

Certain underwriting enterprises may pay us additional revenues for the volume of premium placed with them and for insights into our sales pipeline, our sales capabilities or our risk selection knowledge. These amounts are in excess of the commission and fee revenues discussed above, and not all business we place with underwriting enterprises is eligible for supplemental revenues. Unlike contingent revenues, discussed below, these revenues are primarily a fixed amount or fixed percentage of premium of the underlying eligible insurance contracts. For supplemental revenue contracts based on a fixed percentage of premium, our obligation to the underwriting enterprise is substantially completed upon the effective date of the underlying insurance contract and revenue is fully earned at that time. For supplemental revenue contracts based on a fixed amount, revenue is recognized ratably over the contract period consistent with the performance of our obligations, almost always over an annual term. We receive these revenues on a quarterly or annual basis.

Contingent revenues

Certain underwriting enterprises may pay us additional revenues for our sales capabilities, our risk selection knowledge, or our administrative efficiencies. These amounts are in excess of the commission or fee revenues discussed above, and not all business we place with participating underwriting enterprises is eligible for contingent revenues. Unlike supplemental revenues, also discussed above, these revenues are variable, generally based on growth, the loss experience of the underlying insurance contracts, and/or our efficiency in processing the business. We generally operate under calendar year contracts, but we do not receive these revenues from the underwriting enterprises until the following calendar year, generally in the first and second quarters, after verification of the performance indicators outlined in the contracts. Accordingly, during each reporting period, we must make our best estimate of amounts we have earned using historical averages and other factors to project such revenues. We base our estimates each period on a contract-by-contract basis where available. In certain cases, it is impractical to assess a very large number of smaller contingent revenue contracts, so we use a historical portfolio estimate in aggregate (a practical expedient as defined in Topic 606). Because our expectation of the ultimate contingent revenue amounts to be earned can vary from period to period, especially in contracts sensitive to loss ratios, our estimates might change significantly from quarter to quarter. For example, in circumstances where our revenues are dependent on a full calendar year loss ratio, adverse loss experience in the fourth quarter could not only negate revenue earnings in the fourth quarter, but also trigger the need to reverse revenues previously recognized during the prior quarters. Variable consideration is recognized when we conclude, based on all the facts

and information available at the reporting date, that it is probable that a significant revenue reversal will not occur in future periods.

Sub-brokerage costs

Sub-brokerage costs are excluded from our gross revenues in our determination of total revenues. Sub-brokerage costs represent commissions paid to sub-brokers related to the placement of certain business by our brokerage segment operations. We recognize this contra revenue in the same manner as the commission revenue to which it relates.

Risk Management Segment

RISK MANAGEMENT SEGMENT

Revenues for our risk management segment are comprised of fees generally negotiated (i) on a per-claim or per-service basis, (ii) on a cost‑plus basis, or (iii) as performance-based fees. We also provide risk management consulting services that are recognized as the services are delivered.

Per-claim or per-service fees

Where we operate under a contract with our fee established on a per-claim or per-service basis, our obligation is to process claims for a term specified within the contract. Because it is impractical to recognize our revenues on an individual claim-by-claim basis, we recognize revenue plus an appropriate estimate of our profit margin on a portfolio basis by grouping claims with similar characteristics (a practical expedient as defined in Topic 606). We apply actuarially-determined, historical-based patterns to determine our future service obligations, without applying a present value discount.

Cost-plus fees

Where we provide services and generate revenues on a cost-plus basis, we recognize revenue over the contract period consistent with the performance of our obligations.

Performance-based fees

Certain clients pay us additional fee revenues for our efficiency in managing claims or on the basis of claim outcome effectiveness. These amounts are in excess of the fee revenues discussed above. These revenues are variable, generally based on performance metrics set forth in the underlying contracts. We generally operate under multi-year contracts with fiscal year measurement periods. We do not receive these fees, if earned, until the following year after verification of the performance metrics outlined in the contracts. Each period we base our estimates on a contract-by-contract basis. We must make our best estimate of amounts we have earned using historical averages and other factors to project such revenues. Variable consideration is recognized when we conclude that it is probable that a significant revenue reversal will not occur in future periods.

Reimbursements

Reimbursements represent amounts received from clients reimbursing us for certain third-party costs associated with providing our claims management services. In certain service partner relationships, we are considered a principal because we direct the third party, control the specified service and combine the services provided into an integrated solution. Given this principal relationship, we are required to recognize revenue gross and service partner vendor fees in the operating expense in our consolidated statement of earnings.
Deferred Costs

Deferred Costs

We incur costs to provide brokerage and risk management services. Those costs are either (i) costs to obtain a contract or (ii) costs to fulfill such contract, or (iii) all other costs.

(i)
Costs to obtain - we incur costs to obtain a contract with a client. Those costs would not have been incurred if the contract had not been obtained. Almost all of our costs to obtain are incurred prior to, or on, the effective date of the contract and consist primarily of incentive compensation we pay to our production employees. Our costs to obtain are expensed as incurred as described in Note 4 to these consolidated financial statements.
(ii)
Costs to fulfill - we incur costs to fulfill a contract (or anticipated contract) with a client. Those costs are incurred prior to the effective date of the contract and relate to fulfilling our primary placement obligations to our clients. Our costs to fulfill prior to the effective date are capitalized and amortized on the effective date. These fulfillment
activities include collecting underwriting information from our client, assessing their insurance needs and negotiating their placement with one or more underwriting enterprises. The majority of costs that we incur relate to compensation and benefits of our client service employees. Costs incurred during preplacement activities are expected to be recovered in the future. If the capitalized costs are no longer deemed to be recoverable, then they would be expensed.
(iii)
Other costs that are not costs to obtain or fulfill are expensed as incurred. Examples include other operating costs such as rent, utilities, management costs, overhead costs, legal and other professional fees, technology costs, insurance related costs, communication and advertising, and travel and entertainment. Depreciation, amortization and change in estimated acquisition earnout payable are expensed as incurred.
Investment Income

Investment Income

Investment income primarily includes interest (including revenue from our premium financing operations) and dividend income, which is accrued as it is earned. Net gains on divestitures represent one-time gains related to sales of brokerage related businesses, which are primarily recognized on a cash received basis.

Earnings per Share

Earnings per Share

Basic net earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the reporting period. Diluted net earnings per share is computed by dividing net earnings by the weighted average number of common and common equivalent shares outstanding during the reporting period. Common equivalent shares include incremental shares from dilutive stock options, which are calculated from the date of grant under the treasury stock method using the average market price for the period.

Cash and Cash Equivalents

Cash and Cash Equivalents

Short-term investments, consisting principally of cash and money market accounts that have average maturities of 90 days or less, are considered cash equivalents.

Fiduciary Assets and Liabilities

Fiduciary Assets and Liabilities

Fiduciary assets represent cash held and insurance and reinsurance receivables that relate to our clients and are held on their behalf. Fiduciary liabilities represent the corresponding amounts that are owed to underwriting enterprises on behalf of our clients. In our capacity as an insurance broker, we collect premiums from insureds and, after deducting our commissions and/or fees, remit these premiums to underwriting enterprises. We hold unremitted insurance premiums in a fiduciary capacity until we disburse them, and the use of such funds is restricted by laws in certain states and foreign jurisdictions in which our subsidiaries operate. Various state and foreign agencies regulate insurance brokers and provide specific requirements that limit the type of investments that may be made with such funds. Accordingly, we invest these funds in cash and U.S. Treasury fund accounts. We can earn interest income on these unremitted funds, which is included in investment income in the accompanying consolidated statement of earnings. These unremitted amounts are included in fiduciary assets in the accompanying consolidated balance sheet, with the related liability included in fiduciary liabilities. Additionally, several of our foreign subsidiaries are required by various foreign agencies to meet certain liquidity and solvency requirements. We were in compliance with these requirements at December 31, 2024. This restricted cash is included in cash and cash equivalents net in the accompanying consolidated balance sheet.

Related to our third party administration business and in certain of our brokerage operations, we are responsible for client claim funds that we hold in a fiduciary capacity. We do not earn any interest income on the funds held. These client funds have been included in fiduciary assets, along with a corresponding liability in fiduciary liabilities in the accompanying consolidated balance sheet.

Accounts Receivable

Accounts Receivable

Accounts receivable, net in the accompanying consolidated balance sheet includes accrued agency billed commissions, fees, supplemental commissions, direct bill commissions and contingent commission receivables due to the Company. Accounts receivable are net of allowances for estimated policy cancellations and doubtful accounts. The allowance for estimated policy cancellations was $13.3 million and $9.9 million at December 31, 2024 and 2023, respectively, which represents a reserve for future reversals in commission and fee revenues related to the potential cancellation of client insurance policies that were in force as of each year end. The allowance for doubtful accounts was $21.8 million and $23.0 million at December 31, 2024 and

2023, respectively. We establish the allowance for estimated policy cancellations through a charge to revenues and the allowance for doubtful accounts through a charge to operating expenses. Both of these allowances are based on estimates and assumptions using historical data to project future experience. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. We periodically review the adequacy of these allowances and make adjustments as necessary.

Derivative Instruments

Derivative Instruments

We are exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, we enter into various derivative instruments that reduce these risks by creating offsetting exposures. In the normal course of business, we are exposed to the impact of foreign currency fluctuations that impact our results of operations and cash flows. We utilize a foreign currency risk management program involving foreign currency derivatives that consist of several monthly put/call options designed to hedge a portion of our future foreign currency disbursements through various future payment dates. To mitigate the counterparty credit risk we only enter into contracts with major financial institutions based upon their credit ratings and other factors. These derivative instrument contracts are cash flow hedges that qualify for hedge accounting and primarily hedge against fluctuations between changes in the British pound and Indian Rupee versus the U.S. dollar. Changes in fair value of the derivative instruments are reflected in other comprehensive earnings in the accompanying consolidated balance sheet. The impact of the hedge at maturity is recognized in the income statement as a component of investment income, compensation and operating expenses depending on the nature of the hedged item. We enter into various long-term debt agreements. We use interest rate derivatives, typically swaps, to reduce our exposure to the effects of interest rate fluctuations on the forecasted interest rates for up to three years into the future. These derivative instrument contracts are periodically monitored for hedge ineffectiveness, the amount of which has not been material to the accompanying consolidated financial statements. We do not use derivatives for trading or speculative purposes.
Premium Financing

Premium Financing

Seven subsidiaries of the brokerage segment make short-term loans (generally with terms of twelve months or less) to our clients to finance premiums. These premium financing contracts are structured to minimize potential bad debt expense to us. Such receivables are generally considered delinquent after seven days of the payment due date. In normal course, insurance policies are canceled within one month of the contractual payment due date if the payment remains delinquent. We recognize interest income as it is earned over the life of the contract using the “level-yield” method. Unearned interest related to contracts receivable is included in the receivable balance in the accompanying consolidated balance sheet. The outstanding loan receivable balance was $616.1 million and $685.7 million at December 31, 2024 and 2023, respectively.

Fixed Assets

Fixed Assets

We carry fixed assets at cost, less accumulated depreciation, in the accompanying consolidated balance sheet. 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. Depreciation for fixed assets is computed using the straight-line method over the following estimated useful lives:

 

 

 

Useful Life

Office equipment

 

Three to ten years

Furniture and fixtures

 

Two to ten years

Computer equipment

 

Three to five years

Building

 

Fifteen to forty years

Software

 

Three to five years

Leasehold improvements

 

Shorter of the lease term or useful life of the asset

Intangible Assets

Intangible Assets

Intangible assets represent the excess of cost over the estimated fair value of net tangible assets of acquired businesses. Our primary intangible assets are classified as either goodwill, expiration lists, non-compete agreements or trade names. Expiration lists, non‑compete agreements and trade names are amortized using the straight-line method over their estimated useful lives (two to fifteen years for expiration lists, two to six years for non-compete agreements and two to fifteen years for trade names), while goodwill is not subject to amortization. The establishment of goodwill, expiration lists, non-compete agreements and trade

names and the determination of estimated useful lives are primarily based on valuations we receive from qualified independent appraisers. The calculations of these amounts are based on estimates and assumptions using historical and projected financial information and recognized valuation methods. Different estimates or assumptions could produce different results. We carry identifiable intangible assets at cost, less accumulated amortization, in the accompanying consolidated balance sheet.

We review all of our intangible assets for impairment periodically (at least annually for goodwill) and whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. We perform such impairment reviews at the division (i.e., reporting unit) level with respect to goodwill and at the business unit level for amortizable intangible assets. While goodwill is not amortizable, it is tested for impairment at least annually in the fourth quarter, and more frequently if there are indicators of impairment or whenever business circumstances suggest that the carrying value of goodwill may not be recoverable. We may initially perform a qualitative analysis to determine if it is more likely than not that the goodwill balance is impaired. If a qualitative assessment is not performed or if a determination is made that it is not more likely than not that the fair value of the reporting unit exceeds its carrying amount, then we will perform a quantitative analysis. The fair value of each reporting unit is compared to its carrying value. If the fair value of the reporting unit is less than its carrying value, a non-cash impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit’s fair value with the loss not exceeding the total amount of goodwill allocated to that reporting unit. We completed our 2024 annual assessment in the fourth quarter and concluded goodwill was not impaired, as the fair value of each reporting unit exceeded its carrying value.

The carrying value of amortizable intangible assets attributable to each business or asset group is periodically reviewed by management to determine if there are events or changes in circumstances that would indicate that its carrying amount may not be recoverable. Accordingly, if there are any such changes in circumstances during the year, we assess the carrying value of the amortizable intangible assets by considering the estimated future undiscounted cash flows generated by the corresponding business or asset group. Any impairment identified through this assessment may require that the carrying value of related amortizable intangible assets be adjusted and charged against current period earnings as a component of amortization expense. Based on the results of impairment reviews in 2024, 2023 and 2022, we wrote off $19.4 million, $3.5 million and $2.0 million, respectively, of amortizable intangible assets primarily related to acquisitions (made prior to 2023) of our brokerage and risk management segments, which is included in amortization expense in the accompanying consolidated statement of earnings. The determinations of impairment indicators and fair value are based on estimates and assumptions related to the amount and timing of future cash flows and future interest rates. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein.

Income Taxes

Income Taxes

Our tax rate reflects the statutory tax rates applicable to our taxable earnings and tax planning in the various jurisdictions in which we operate. Significant judgment is required in determining the annual effective tax rate and in evaluating uncertain tax positions. We report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We evaluate our tax positions using a two-step process. The first step involves recognition. We determine whether it is more likely than not that a tax position will be sustained upon tax examination based solely on the technical merits of the position. The technical merits of a tax position are derived from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings and case law) and their applicability to the facts and circumstances of the position. If a tax position does not meet the “more likely than not” recognition threshold, we do not recognize the benefit of that position in the financial statements. The second step is measurement. A tax position that meets the “more likely than not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that has a likelihood of greater than 50% of being realized upon ultimate resolution with a taxing authority.

Uncertain tax positions are measured based upon the facts and circumstances that exist at each reporting period and involve significant management judgment. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. We recognize interest and penalties, if any, related to unrecognized tax benefits in our provision for income taxes.

Tax law requires certain items to be included in our tax returns at different times than such items are reflected in the financial statements. As a result, the annual tax expense reflected in our consolidated statements of earnings is different than that reported in our tax returns. Some of these differences are permanent, such as expenses that are not deductible in our tax returns, and some differences are temporary and reverse over time, such as depreciation expense and amortization expense deductible for income tax purposes. Temporary differences create deferred tax assets and liabilities. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which a tax payment has been deferred, or expense which has been deducted

in the tax return but has not yet been recognized in the financial statements. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which a benefit has already been recorded in the financial statements.

We establish or adjust valuation allowances for deferred tax assets when we estimate that it is more likely than not that future taxable income will be insufficient to fully use a deduction or credit in a specific jurisdiction. In assessing the need for the recognition of a valuation allowance for deferred tax assets, we consider whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized and adjust the valuation allowance accordingly. We evaluate all significant available positive and negative evidence as part of our analysis. Negative evidence includes the existence of losses in recent years. Positive evidence includes the forecast of future taxable income by jurisdiction, tax-planning strategies that would result in the realization of deferred tax assets and the presence of taxable income in prior carryback years. The underlying assumptions we use in forecasting future taxable income require significant judgment and take into account our recent performance. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences are deductible or creditable.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair value accounting establishes a framework for measuring fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). This framework includes a fair value hierarchy that prioritizes the inputs to the valuation technique used to measure fair value.

The classification of a financial instrument within the valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels of the hierarchy in order of priority of inputs to the valuation technique are defined as follows:

Level 1 - Valuations are based on unadjusted quoted prices in active markets for identical financial instruments;
Level 2 - Valuations are based on quoted market prices, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument; and
Level 3 - Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management’s own assumptions about the assumptions a market participant would use in pricing the financial instrument.

The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety.

The carrying amounts of financial assets and liabilities reported in the accompanying consolidated balance sheet for cash and cash equivalents, fiduciary assets, accounts receivable, other current assets, fiduciary liabilities, accrued compensation and other accrued liabilities and deferred revenue - current, at December 31, 2024 and 2023, approximate fair value because of the short-term duration of these instruments. See Note 3 to these consolidated financial statements for the fair values related to the establishment of intangible assets and the establishment and adjustment of earnout payables. See Note 7 to these consolidated financial statements for the fair values related to borrowings outstanding at December 31, 2024 and 2023 under our debt agreements. See Note 12 to these consolidated financial statements for the fair values related to investments at December 31, 2024 and 2023 under our defined benefit pension plan.
Litigation

Litigation

We are the defendant in various legal actions related to claims, lawsuits and proceedings incidental to the nature of our business. We record liabilities for loss contingencies, including legal costs (such as fees and expenses of external lawyers and other service providers) to be incurred, when it is probable that a liability has been incurred on or before the balance sheet date and the amount of the liability can be reasonably estimated. We do not discount such contingent liabilities. To the extent recovery of such losses and legal costs is probable under our insurance programs, we record estimated recoveries concurrently with the losses recognized. Significant management judgment is required to estimate the amounts of such contingent liabilities and the related insurance recoveries. In order to assess our potential liability, we analyze our litigation exposure based on available information, including consultation with outside counsel handling the defense of these matters. As these liabilities are uncertain by their

nature, the recorded amounts may change due to a variety of different factors, including new developments in, or changes in approach, such as changing the settlement strategy as applicable to each matter.
Retention Bonus Arrangements

Retention Bonus Arrangements

In connection with the hiring and retention of both new talent and experienced personnel, including our senior management, brokers and other key personnel, we have entered into various agreements with key employees setting up the conditions for the cash payment of certain retention bonuses. These bonuses are an incentive for these employees to remain with the Company, for a fixed period of time, to allow us to capitalize on their knowledge and experience. We have various forms of retention bonus arrangements; some are paid up front and some are paid at the end of the term, but all are contingent upon successfully completing a minimum period of employment. A retention bonus that is paid to an employee upfront that is contingent on a certain minimum period of employment, will be initially classified as a prepaid asset and amortized to compensation expense as the future services are rendered over the duration of the stay period. A retention bonus that is paid to an employee at the end of the term that is contingent on a certain minimum period of employment, will be accrued as a liability through compensation expense as the future services are rendered over the duration of the stay period. If an employee leaves prior to the required time frame to earn the retention bonus outright, then all or any portion that is ultimately unearned or refundable, and recovered by the Company if prepaid, is forfeited and reversed through compensation expense.

Stock-Based Compensation

Stock-Based Compensation

We have several employee equity-settled and cash-settled share-based compensation plans. Equity-settled share-based payments to employees include grants of stock options, performance stock units and restricted stock units and are measured based on estimated grant date fair value. We have elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the dates of grant. Performance stock units are measured on the probable outcome of the performance conditions applicable to each grant. Restricted stock units are measured based on the fair market values of the underlying stock on the dates of grant. Shares are issued on the vesting dates net of the minimum statutory tax withholding requirements, as applicable, to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number of performance stock units and restricted stock units outstanding. Furthermore, we record the liability for withholding amounts to be paid by us as a reduction to additional paid-in capital when paid.

Cash-settled share-based payments to employees include awards under our Performance Unit Program and stock appreciation rights. The fair value of the amount payable to employees in respect of cash-settled share-based payments is recognized as compensation expense, with a corresponding increase in liabilities, over the vesting period. The liability is remeasured at each reporting date and at settlement date. Any changes in fair value of the liability are recognized as compensation expense.

We recognize share-based compensation expense over the requisite service period for awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs from original estimates.

Employee Stock Purchase Plan

Employee Stock Purchase Plan

We have an employee stock purchase plan (which we refer to as the ESPP), under which the sale of 8.0 million shares of our common stock has been authorized. Eligible employees may contribute up to 15% of their compensation towards the quarterly purchase of our common stock at a purchase price equal to 95% of the lesser of the fair market value of our common stock on the first business day or the last business day of the quarterly offering period. Eligible employees may annually purchase shares of our common stock with an aggregate fair market value of up to $25,000 (measured as of the first day of each quarterly offering period of each calendar year), provided that no employee may purchase more than 2,000 shares of our common stock under the ESPP during any calendar year. At December 31, 2024, 4.7 million shares of our common stock was reserved for future issuance under the ESPP.

Defined Benefit Pension Plans

Defined Benefit Pension Plans

We recognize in our consolidated balance sheet, an asset for our defined benefit pension plans’ overfunded status or a liability for our plans’ underfunded status. We recognize changes in the funded status of our defined benefit pension plans in comprehensive earnings in the year in which the changes occur. We use December 31 as the measurement date for our plans’ assets and benefit obligations. See Note 12 to these consolidated financial statements for additional information required to be disclosed related to our defined benefit pension plans.

Effect of New Accounting Pronouncements Effect of New Accounting Pronouncements

Segment Reporting

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires that an entity report segment information in accordance with Topic 280, Segment Reporting. The amendment in the ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted this ASU as of December 31, 2024, which affected our segment disclosures. See Note 19 to these consolidated financial statements for further detail regarding the impact of this ASU.

Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The amendment in the ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024. We are currently evaluating the impact of the new standard on our consolidated financial statements which is expected to result in enhanced disclosures.

Climate Risk Disclosures

In March 2024, the SEC issued final climate-related disclosure rules that will require disclosure of material climate-related risks and material direct greenhouse gas emissions from operations owned or controlled (Scope 1) and/or material indirect greenhouse gas emissions from purchased energy consumed in owned or controlled operations (Scope 2). Additionally, the rules require disclosure in the notes to the financial statements of the effects of severe weather events and other natural conditions, subject to certain materiality thresholds. The disclosure requirements were scheduled to begin phasing in for annual reports and registration statements including financial information with respect to annual periods beginning in calendar year 2025. On April 4, 2024, the SEC issued an order staying the rules during the pendency of a number of legal challenges to the rules’ validity. We are continuing to monitor these developments while evaluating the impact of the rules on our consolidated financial statements, which are expected to result in additional disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting–Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) included within income statement expense captions. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard updates are to be applied prospectively with the option for retrospective application. We are currently evaluating the impact of adoption of the standard update on its financial statement disclosures.
