Information Concerning Forward-Looking Statements

This report contains certain statements related to future results, or states our intentions, beliefs and expectations or predictions for the future, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Forward‑looking statements relate to expectations or forecasts of future events. Such statements use words such as “anticipate,” “believe,” “estimate,” “expect,” “contemplate,” “forecast,” “project,” “intend,” “plan,” “potential,” and other similar terms, and future or conditional tense verbs like “could,” “may,” “might,” “see,” “should,” “will” and “would.” You can also identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. For example, we may use forward-looking statements when addressing topics such as: market and industry conditions, including competitive and pricing trends; acquisition strategy including the expected size of our acquisition program; the expected impact of acquisitions and dispositions; the development and performance of our services and products; changes in the composition or level of our revenues or earnings; our cost structure and the size and outcome of cost-saving or restructuring initiatives; future capital expenditures; future debt levels and anticipated actions to be taken in connection with maturing debt; future debt to earnings ratios; the outcome of contingencies; dividend policy; pension obligations; cash flow and liquidity; capital structure and financial losses; future actions by regulators; the outcome of existing regulatory actions, investigations, reviews or litigation; the impact of changes in accounting rules; financial markets; interest rates; foreign exchange rates; matters relating to our operations; income taxes; expectations regarding our investments, including our clean energy investments; human capital management, including diversity and inclusion initiatives; environmental, social and governance matters, including climate-resilience products and services and carbon emissions; and integrating recent acquisitions. These forward‑looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from either historical or anticipated results depending on a variety of factors.

Potential factors that could impact results include:

•

The ongoing COVID-19 pandemic, including its effect on the economy, our employees, our clients, the regulatory environment and our operations;

•

The current or a future economic downturn or unstable economic conditions, whatever the cause, including the effects of the COVID-19 pandemic, or other factors like Brexit, worsening international relations, tariffs, trade wars, political violence and unrest in the U.S. or around the world, or climate change and other long-term environmental, social and governance matters and global health risks;

•

Volatility or declines in premiums or other adverse trends in the insurance industry;

•

Competitive pressures, including as a result of innovation, in each of our businesses;

•

Risks that could negatively affect the success of our acquisition strategy, including the impact of current economic uncertainty on our ability to source, review and price acquisitions, continuing consolidation in our industry and growing interest in acquiring insurance brokers on the part of private equity firms and newly public insurance brokers, which could make it more difficult to identify targets and could make them more expensive, the risk that we may not receive timely regulatory approval of desired transactions, execution risks, integration risks, poor cultural fit, the risk of post-acquisition deterioration leading to intangible asset impairment charges, and the risk we could incur or assume unanticipated liabilities such as cybersecurity issues or those relating to violations of anti-corruption and sanctions laws;

•

Failure to successfully and cost-effectively integrate recently acquired businesses and their operations or fully realize synergies from such acquisitions in the expected time frame;

•

Cyber attacks or other cybersecurity incidents including the ransomware incident referred to elsewhere in this report under “Update on Ransomware Incident”; improper disclosure of confidential, personal or proprietary data; and changes to laws and regulations governing cybersecurity and data privacy;

•

Risks arising from changes in U.S. or foreign tax laws, including the current U.S. president’s administration’s potential reversal of all or part of the U.S. Tax Cuts and Jobs Act 2017 (which we refer to as the TCJA) and related regulations;

•

Uncertainty from the expected discontinuance of LIBOR;

•

Our failure to attract and retain experienced and qualified talent, including our senior management team, and the risk of our CEO or another senior executive contracting COVID-19;

•

Risks arising from our international operations, including the risks posed by political and economic uncertainty in certain countries (such as the risks posed by Brexit), risks related to maintaining regulatory and legal compliance across multiple jurisdictions (such as those relating to violations of anti-corruption, sanctions and privacy laws), rising global tensions and protectionism, and risks arising from the complexity of managing businesses across different time zones, languages, geographies, cultures and legal regimes that conflict with one another at times;

- 2 -

•

Risks particular to our risk management segment, including reduced economic activity due to COVID-19 further reducing claim activity, any slowing of the trend toward outsourcing claims administration, and of the concentration of large amounts of revenue with certain clients;

•

Risks particular to our benefit consulting operations, including reduced economic activity due to COVID-19 further reducing fee revenue from special projects and risks to the business posed by potential changes to health legislation under the current U.S. president’s administration;

•

The higher level of variability inherent in contingent and supplemental revenues versus standard commission revenues, particularly in light of the changed revenue recognition accounting standard;

•

Sustained increases in the cost of employee benefits;

•

A disaster or other significant disruption to business continuity; including natural disasters and political violence and unrest in the U.S. or elsewhere around the world;

•

Damage to our reputation including as a result of environmental, social and governance (ESG) matters;

•

Climate risks, including the risk of a systemic economic crisis and disruptions to our business caused by the transition to a low-carbon economy;

•

Our failure to apply technology effectively in driving value for our clients through technology-based solutions, or failure to gain internal efficiencies and effective internal controls through the application of technology and related tools;

•

Violations or alleged violations of the U.S. Foreign Corrupt Practices Act (which we refer to as FCPA), the U.K. Bribery Act 2010 or other anti-corruption laws and the Foreign Account Tax Compliance provisions of the Hiring Incentives to Restore Employment Act (which we refer to as FATCA);

•

The outcome of any existing or future investigation, review, regulatory action or litigation;

•

Unfavorable determinations related to contingencies and legal proceedings;

•

Significant changes in foreign exchange rates;

•

Changes to our financial presentation from new accounting estimates and assumptions;

•

Risks related to our clean energy investments, including intellectual property claims, utilities switching from coal to natural gas or renewable energy sources, environmental and product liability claims, environmental compliance costs and the risk of disallowance by the Internal Revenue Service (which we refer to as the IRS) of previously claimed tax credits;

•

The risk that our outstanding debt adversely affects our financial flexibility and restrictions and limitations in the agreements and instruments governing our debt;

•

The risk we may not be able to receive dividends or other distributions from subsidiaries;

•

The risk of share ownership dilution when we issue common stock as consideration for acquisitions and for other reasons; and

•

Volatility of the price of our common stock.

- 3 -

Forward-looking statements are not guarantees of future performance. They involve risks, uncertainties and assumptions, including the risk factors referred to above, and are currently, or in the future could be, amplified by the COVID-19 pandemic. Our future performance and actual results may differ materially from those expressed in forward-looking statements. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of, and are based on information available to us on, the date of the applicable document. Many of the factors that will determine these results are beyond our ability to control or predict. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Forward-looking statements speak only as of the date that they are made, and we do not undertake any obligation to update any such statements or release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date of this report or to reflect new information, future or unexpected events or otherwise, except as required by applicable law or regulation.

A detailed discussion of the factors that could cause actual results to differ materially from our published expectations is contained under the heading “Risk Factors” in our filings with the Securities and Exchange Commission (SEC), including our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, and any other reports we file with the SEC in the future.

Notes to ~~September 30, 2017~~March 31, 2021 Consolidated Financial Statements (Unaudited)

1. Summary of Significant Accounting Policies

~~Nature of Operations and Basis of Presentation~~

Terms Used in Notes to Consolidated Financial Statements

ASC - Accounting Standards Codification.

ASU - Accounting Standards Update.

FASB - The Financial Accounting Standards Board.

GAAP - U.S. generally accepted accounting principles.

IRC - Internal Revenue Code.

IRS - Internal Revenue Service.

Underwriting enterprises - Insurance companies, reinsurance companies and various other forms of risk-taking entities, including intermediaries of underwriting enterprises.

Nature of Operations and Basis of Presentation

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 3 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 companies and entities of all types, including commercial, not-for-profit, public entities, and, to a lesser extent, individuals, in the areas of insurance placement, 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, not-for-profit, captive and public 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 ~~to a wide variety of commercial, industrial, institutional and governmental organizations through three reportable segments. Commission and fee revenue generated~~provided by underwriting enterprises. The corporate segment reports the ~~brokerage segment is primarily~~financial information related to our debt and other corporate costs, clean energy investments, external acquisition‑related expenses and the ~~negotiation and placement~~impact of ~~insurance~~foreign currency translation. Clean energy investments consist of our investments in limited liability companies that own 35 commercial clean coal production facilities that can produce refined coal using Chem-Mod LLC’s proprietary technologies. We believe these operations produce refined coal that qualifies for ~~our clients. Fee revenue generated~~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 to organize captives, pools, specialized underwriters or risk-retention groups. Rather, capital necessary for covering losses is provided by ~~the risk management segment is primarily related to claims management, information management, risk control consulting (loss control) services and appraisals in the property/casualty market.~~ underwriting enterprises.

Investment income and other ~~revenue~~revenues are primarily generated from our premium financing operations, ~~and~~ our ~~investment portfolio, which includes~~ invested cash and restricted ~~funds,~~cash we hold on behalf of our clients, as well as clean energy ~~and other~~ 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.

We are headquartered in Rolling Meadows, Illinois, have operations in 3456 countries and offer client-service capabilities in more than 150 countries globally through a network of correspondent insurance brokers and consultants.

- 12 -

We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements have been omitted pursuant to such rules and regulations. The unaudited consolidated financial statements included herein are, in the opinion of management, prepared on a basis consistent with our audited consolidated financial statements for the year ended December 31, ~~2016, except as disclosed in Note 2,~~2020, and include all normal recurring adjustments necessary for a fair presentation of the information set forth. The quarterly results of operations are not necessarily indicative of the results of operations to be reported for subsequent quarters or the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form10-K for the year ended December 31, ~~2016.~~2020. In the preparation of our unaudited consolidated financial statements as of ~~September 30, 2017,~~March 31, 2021, 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 therein.

~~Effect of New Accounting Pronouncements~~

~~Hedge Accounting~~Use of Estimates

~~In August 2017,~~The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the ~~Financial Accounting Standards Board (which we refer to as the FASB) issued Accounting Standards Update (which we refer to as ASU)No. 2017-12,~~ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new guidance amends the hedge accounting model in the current guidance to enable entities to better portray the economics of their risk management activitiesamounts reported in the financial statements and ~~enhance~~accompanying notes. These accounting principles require us to make estimates and assumptions that affect the ~~transparency~~reported amounts of assets and ~~understandability of hedge results. The new guidance requires revised tabular disclosures that focus on the effect of hedge accounting by income statement line~~liabilities and revenues and expenses, and the disclosure of ~~the cumulative basis adjustments to the hedged~~contingent assets and liabilities ~~in fair value hedges. Certain additional disclosures are also required for hedge relationships designated under thelast-of-layer~~ method. The current guidance that requires entities to disclose hedge ineffectiveness has been eliminated because this amount will no longer be separately measured. Under the new guidance, entities will apply the amendments to cash flow and net investment hedge relationships that exist onat the date of adoption using a modified retrospective approach (i.e., with a cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date). The new guidance also provides transition relief to make it easier for entities to apply certain amendments to existing hedges (including fair value hedges) where the hedge documentation needs to be modified. The presentation and disclosure requirements will be applied prospectively. The new guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted in any interim period or annual year before the effective date. If the guidance is early adopted in an interim period, any adjustments would be reflected as of the beginning of the fiscal year that includes that interim period. We are currently assessing the impact that adopting this new guidance will have on our consolidated financial statements.

~~Business Combinations~~

~~In January 2017, the FASB issued ASUNo. 2017-01,~~ Business Combinations (Topic 805) Clarifying the Definition of a Business. The new guidance clarifies the definition of a business with the objective of adding information to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. Management does not anticipate that this new guidance will have a material impact on our consolidated financial statements upon adoption.

~~- 8 -~~

~~Intangibles - Goodwill and Other~~

~~In January 2017, the FASB issued ASUNo. 2017-04,~~ Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new guidance eliminates Step 2 of the goodwill impairment test. Instead, the updated guidance requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of the reporting unit to its carrying value, and recognizing a~~non-cash~~ impairment charge 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. The new guidance is effective beginning January 1, 2020, with early adoption permitted, and will be applied on a prospective basis. The new guidance currently has no impact on our consolidated financial statements; however, we will evaluate the impact of this updated guidance on future annual or interim goodwill impairment tests performed.

~~Leases~~

~~In February 2016, the FASB issued ASU No.2016-02,~~ ~~Leases (Topic 842). Under this new accounting guidance, an entity is required to recognizeright-of-use~~ assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. This new guidance offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. This new guidance is effective for first quarter 2019, and requires a modified retrospective adoption, with early adoption permitted. Under the modified retrospective approach, lessees are required to recognize and measure leases at the beginning of the earliest period presented. In addition, the modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset.

~~While we are continuing to assess all potential impacts of the new guidance, we anticipate this guidance will have an impact on~~ our consolidated financial statements. We ~~currently~~periodically evaluate our estimates and assumptions, including those relating to the valuation of goodwill and other intangible assets, right-of-use assets, investments (including our IRC Section 45 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 ~~most significant~~future as more information becomes known, which could impact ~~relates to our real estate operating leases~~the amounts reported and disclosed in the ~~related recognition~~notes herein.

2. Effect of~~right-of-use~~ ~~assets and lease liabilities in both noncurrent assets and noncurrent liabilities in our consolidated balance sheet. See Note 13 to these unaudited consolidated financial statements~~ New Accounting Pronouncements

Simplifying the Accounting for ~~details on our current lease arrangements.~~

~~Stock Compensation~~Income Taxes

In ~~May 2017~~December 2019, the FASB issued ASU ~~No.2017-09,~~ ~~Compensation - Stock Compensation~~2019-12, “Income Taxes (Topic ~~718)~~740): ~~Scope of Modification~~Simplifying the Accounting ~~(ASU2017-09).~~ ~~This new~~for IncomeTaxes,” which is intended to simplify various aspects related to accounting ~~guidance provides information about which changes~~for income taxes. ASU 2019-12 removes certain exceptions to the ~~terms or conditions of a share-based payment award require an entity to apply modification accounting~~general principles in Topic ~~718. ASU2017-09~~ ~~is effective for financial statements issued for annual reporting periods beginning after December 15, 2017~~740 and ~~interim periods within those years. Earlier application is permitted. We do not expect that the adoption of this new~~also clarifies and amends existing guidance ~~will have a material impact on our consolidated financial statements as we historically have not made changes~~ to ~~the terms or conditions of an outstanding share-based payment award.~~

~~In March 2016, the FASB issued ASUNo. 2016-09,~~ ~~Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, (ASU2016-09).~~ This new accounting guidance requires that companies recognize the income tax effects of awards in the income statement when the awards vest or are settled, rather than recognizing the tax benefits in excess of compensation costs through stockholders’ equity. ASU~~2016-09~~ provides that this requirement be applied prospectively. As it relates to forfeitures, the guidance allows for companies to choose whether to continue to estimate forfeitures or account for forfeitures as they occur. This new guidance was effective in first quarter 2017 and has been applied by us. Due to the adoption of the new guidance, we recognized the income tax benefit of stock based awards that vested or were settled in the three-month and nine-month periods ended September 30, 2017 of $1.8 million and $11.9 million, respectively, in our consolidated statement of earnings. The income tax benefit of stock based awards that vested or were settled in the three-month and nine-month periods ended September 30, 2016 were $1.7 million and $4.8 million, respectively, that was recognized in our consolidated stockholders’ equity. Additionally, our consolidated statement of cash flows now presents excess tax benefits as an operating activity, rather than as a financing activity, applied prospectively. Finally, we elected to continue to estimate forfeitures based on historical data and recognize forfeitures over the vesting period of the award.

~~- 9 -~~

~~Cash Receipts and Cash Payments~~

~~In August 2016, the FASB issued ASU No.2016-15,~~ ~~Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, (ASU2016-15).~~improve consistent application. The amendments in ASU~~2016-15~~ ~~address several specific cash flow issues and apply to all entities that~~ 2019-12 are ~~required to present a statement of cash flows under ASC 230, Statement of Cash Flows. This new guidance is~~ effective for public business entities for fiscal years beginning after December 15, ~~2017, and~~2020, including interim periods ~~within those fiscal years, with early adoption permitted.~~ therein. We ~~early~~ adopted ~~this guidance in first quarter 2017.~~

The adoption of this guidance resulted in a change to our classification whereby contingent payments on acquisitions that are up to the acquisition date fair value have been presented in financing activities and those payments in excess of the acquisition date fair value have been presented in operating activities. Historically these payments have all been included in investing activities. Accordingly, in our September 30, 2016 consolidated statement of cash flows, we reclassified $19.5 million and $41.7 million of payments from investing activities to operating activities and financing activities, respectively, to conform to the current year presentation. The modifications can be seen in our statement of cash flows.

~~Income Taxes~~

~~In October 2016, the FASB issued ASU No.2016-16,~~ Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This new accounting guidance allows entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Current guidance does not allow recognition until the asset has been sold to an outside party. This new guidance is effective beginning January 1, 2018 and is to be applied on a modified retrospective basis. Early adoption is permitted. Management does not anticipate that this new guidance ~~will~~effective January 1, 2021. The adoption did not have ~~a material~~any impact on our consolidated financial ~~statements upon adoption.~~statements.

~~Restricted Cash~~3. Business Combinations

~~In November 2016, the FASB issued ASU No.2016-18,~~ Statement of Cash Flows (Topic 230): Restricted Cash. This new accounting guidance addresses the classification and presentation of changes in restricted cash on the statement of cash flows under Topic 230, Statement of Cash Flows. This guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted for all entities. The adoption of this new guidance will change the presentation in our consolidated statement of cash flows as it will require us to show the changes in the total of cash, cash equivalents and restricted cash in the statement of cash flows.

~~Revenue Recognition~~

~~In May 2014, the FASB issued ASUNo. 2014-09,~~ Revenue from Contracts with Customers, as a new Topic, ASC 606, which will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principal of the new accounting guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Amendments to ASC Topic 340, Other Assets and Deferred Costs, require the capitalization of costs to obtain and costs to fulfill customer contracts, which are currently expensed as incurred. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The new guidance is effective for us in first quarter 2018, and early adoption is permitted beginning in first quarter 2017. Two methods of transition are permitted upon adoption; full retrospective and modified retrospective. Under the full retrospective method, prior periods would be restated under the new revenue standard, providing a comparable view across all periods presented. Under the modified retrospective method, prior periods would not be restated. Rather, revenues and other disclosures for~~pre-2018~~ periods would be provided in the notes to the financial statements as previously reported under the current revenue standard. We will adopt this new guidance in first quarter 2018 and we currently anticipate adopting the new guidance using the full retrospective method to restate each prior reporting period presented.

A full assessment to determine the impacts of the new accounting standard has been performed. We are currently implementing new accounting and operational processes which are a result of the new guidance and are analyzing the impact of these changes. We anticipate this standard will have a material impact on individual lines in our consolidated financial statements, but we do not expect it will have as material an impact on our results of operations on an annual basis. The primary impacts of the new standard to our product and service lines are anticipated to be as follows:

~~- 10 -~~

~~Brokerage segment~~

~~Revenue~~- We currently recognize revenue for certain of our brokerage activities, such as installments on agency bill, direct bill and contingent commission revenue, over a period of time either due to the transfer of value to our customers or as the remuneration becomes determinable. Under the new guidance, these revenues will be substantially recognized at a point in time on the effective date of the associated policies when control of the policy transfers to the customer. Conversely under the new guidance we may need to defer certain revenues to reflect delivery of services over the contract period. As a result, revenue from certain arrangements will be recognized in earlier periods under the new guidance in comparison to our current accounting policies, and others will be recognized in later periods. The net effect of all of these changes on the timing and amount of revenue recognized will be a net increase in revenue recognized for our annual reporting periods with a shift in the timing of revenue recognized in the interim periods to the first quarter from the other three quarters.

The primary reason for the increase in the amount of revenue recognized relates to our employee benefits business. Historically we have recognized this revenue throughout the contract period as underlying client exposure units became certain. Under the new guidance, the full year revenue under each of these contracts will be estimated at the effective date of the underlying policies resulting in acceleration of revenue recognized, with a reassessment at each reporting date. This also will cause a shift in the timing of revenue recognized in the interim periods as a majority of these annual contracts incept in the first quarter. Partially offsetting this interim impact will be the recognition of contingent commissions related to all of our brokerage business as these revenues will be estimated and accrued throughout the year as the underlying business is placed with the insurance carriers rather than our historical recognition where the majority of these were recognized in the first quarter, typically when we received cash or the related policy detail or other carrier specific information from the insurance carrier.

~~Expense -~~ The assets recognized for the costs to obtain and/or fulfill a contract will be amortized on a systematic basis that is consistent with the transfer of the services to which the asset relates. For the vast majority of our contracts, the renewal period is one year or less and renewal costs are commensurate with the initial contract, thus we plan to apply a practical expedient and recognize the costs of obtaining a contract as an expense when incurred. We are quantifying and analyzing the impact of the costs to fulfill a contract. We do not expect the net impact on an annual basis of deferring and amortizing these costs to be material, but it will have an impact on the timing of expenses recognized in the interim periods.

~~Risk management segment~~

~~Revenue~~ - Under the new guidance, when we have the obligation to adjust claims until closure and are compensated on a per claim basis, we will recognize the full amount of the claim revenue upon notification of the claim and defer certain revenues to reflect delivery of services over the claim handling period. When our obligation is to provide claims services throughout a contract period, we will recognize revenue ratably across that contract period. As such, we anticipate the net impact of the new guidance will require more initial revenue deferral and recognition over a longer period of time than under our current accounting policies.

~~Expense -~~The assets recognized for the costs to obtain and/or to fulfill a contract will be amortized on a systematic basis that is consistent with the transfer of the services to which the asset relates. We do not believe we have material costs to obtain and we are quantifying the impact of our costs to fulfill. We do not expect the net impact of deferring and amortizing these costs to obtain or to fulfill to be material on our annual or interim reporting periods.

~~Corporate segment~~

We expect that the timing related to recognition of revenue in our corporate segment will remain substantially unchanged.

On September 20, 2017, we signed a definitive agreement to acquire substantially all the assets of DiBrina Group headquartered in Sudbury, Ontario, Canada, for approximately $42.8 million of cash consideration plus a maximum potential earnout of approximately $24.0 million. The transaction was subject to customary closing conditions and closed on October 4, 2017.

Common shares issued in connection with acquisitions are valued at closing market prices as of the effective date of the applicable ~~acquisition.~~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 atwo- 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 5.0% to ~~17.0%~~15.0% for our ~~2017~~2021 acquisitions. We estimated future payments using the earnout formula and performance targets specified in each purchase agreement and ~~these~~the financial ~~projections.~~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. ~~These~~The discount ~~rates generally ranged from 7.5% to~~rate was 9.0% for all of our ~~2017~~2021 acquisitions. 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 the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we recognized ~~$4.9~~$9.0 million and $4.3 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. During the nine-month periods ended September 30, 2017 and 2016, we recognized $15.2 million and $12.5$10.7 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 the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we recognized ~~$5.7~~$6.0 million of expense and ~~$0.2~~$99.6 million of income, respectively, related to net adjustments in the estimated fair value of the liability for earnout obligations in connection with revised projections of future performance for 3125 and 27 acquisitions, respectively. In addition, during the nine-month periods ended September 30, 2017 and 2016, we recognized $12.3 million and $8.7 million of expense, respectively, related to net adjustments in the estimated fair value of earnout obligations in connection with revised projections of future performance for 89 and 7775 acquisitions, respectively. The aggregate amount of maximum earnout obligations related to acquisitions was ~~$563.9~~$1,146.1 million as of ~~September 30, 2017,~~March 31, 2021, of which ~~$274.3~~$623.0 million was recorded in ~~our~~the consolidated balance sheet as of ~~September 30, 2017,~~March 31, 2021, based on the estimated fair value of the expected future payments to be ~~made.~~made, of which approximately $518.2 million can be settled in cash or stock at our option and $104.8 million must be settled in cash.

The following is a summary of the estimated fair values of the net assets acquired at the date of each acquisition made in the ~~nine-month~~three‑month period ended ~~September 30, 2017~~March 31, 2021 (in millions):

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 ~~services~~markets and ~~risk management industries~~in third party claims administration services 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~~non-compete~~ ~~agreements~~ trade names in the amounts of ~~$228.1~~$288.5 million, ~~$188.9~~$196.4 million, $18.2 million and ~~$2.8~~$3.2 million, respectively, within the brokerage and risk management segments.

Provisional estimates of fair value are established at the time of each acquisition and are subsequently reviewed within the first year of operations subsequent to the acquisition date to determine the necessity for adjustments. The fair value of the tangible assets and liabilities for each applicable acquisition at the acquisition date approximated their carrying values. 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 ~~2.0%~~3.0% to ~~3.3%~~4.8% and ~~5.0%~~4.3% to ~~10.0%~~16.1%,

~~- 13 -~~

respectively, for our ~~2016 and 2017~~2020 acquisitions for which valuations were performed in ~~2017.~~2021. We estimate the fair value as the present value of the benefits anticipated from ownership of the subject ~~customer~~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 ~~12.0%~~10.0% to ~~14.0%~~11.5% for our ~~2016 and 2017~~2020 acquisitions for which valuations were performed in ~~2017.~~2021. The fair value ofnon-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 variousnon-compete scenarios.

Expiration lists,non-compete agreements and trade names related to our acquisitions are amortized using the straight-line method over their estimated useful lives ~~(three~~(two to fifteen years for expiration lists, ~~three~~two to ~~five~~six years fornon-compete agreements and ~~three~~two to ~~five~~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 ~~fair value~~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. Based on the results of impairment reviews during the three-month ~~and nine-month~~ periods ended ~~September 30, 2017,~~March 31, 2021 and 2020, we wrote off ~~$4.5~~$5.1 million and ~~$6.2~~$45.8 million, respectively, of amortizable ~~intangible~~ assets related to the brokerage ~~segment. Based on the results of impairment reviews during the three-month~~ and ~~nine-month periods ended September 30, 2016, we wrote off $1.5 million and $1.8 million, respectively, of amortizable intangible assets related to the brokerage segment.~~risk management segments.

Of the ~~$188.9~~$196.4 million of expiration lists, ~~and $2.8~~$18.2 million ofnon-compete agreements and $3.2 million of trade names related to our acquisitions made during the ~~nine-month~~three-month period ended ~~September 30, 2017, $49.8~~March 31, 2021, $116.0 million, $16.2 million and ~~$2.0~~$3.2 million, respectively, is not expected to be deductible for income tax purposes. Accordingly, we recorded a deferred tax liability of ~~$13.7~~$25.3 million, and a corresponding amount of goodwill, in the ~~nine-month~~three-month period ended ~~September 30, 2017,~~March 31, 2021, related to the nondeductible amortizable intangible assets.

4. Contracts with Customers

Contract Assets and Liabilities/Contract Balances

Information about unbilled receivables, contract assets and contract liabilities from contracts with customers is as follows (in millions):

	March 31, 2021		December 31, 2020
Unbilled receivables	$	911.1	$	603.1
Deferred contract costs		65.4		102.0
Deferred revenue		590.7		541.3

The unbilled receivables, which are included in premiums 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 includes 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.

Significant changes in the deferred revenue balances, which include foreign currency translation adjustments, during the period are as follows (in millions):

				Risk
	Brokerage			Management			Total
Deferred revenue at December 31, 2020	$	354.7		$	186.6		$	541.3

Deferred revenue recognized from business acquisitions		7.1			—			7.1
Deferred revenue at March 31, 2021	$	392.2		$	198.5		$	590.7

Revenue recognized during the three-month period ended March 31, 2021 in the table above included revenue from 2020 acquisitions that would not be reflected in prior periods.

Remaining Performance Obligations

Remaining performance obligations represent the portion of the contract price for which work has not been performed. As of March 31, 2021, the aggregate amount of the contract price allocated to remaining performance obligations was $590.7 million. The estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period is as follows (in millions):

~~Other Current Assets~~

Deferred Contract Costs

We capitalize costs incurred to fulfill contracts as deferred contract costs which are included in other current assets in our consolidated balance sheet. Deferred contract costs were $65.4 million and $102.0 million as of March 31, 2021 and December 31, 2020, respectively. Capitalized fulfillment costs are amortized to expense on the contract effective date. The amount of amortization of the deferred contract costs was $126.2 million and $120.8 million for the three-month periods ended March 31, 2021 and 2020, 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.

5. Other Financial Data

Other Current Assets

Major classes of other current assets consist of the following (in millions):


	September 30, 2017		December 31, 2016
					March 31, 2021		December 31, 2020
Premium finance advances and loans	$	292.5	$	241.2	$	375.0	$	442.7
Accrued supplemental, direct bill and other receivables		172.4		177.2		333.0		361.7
Refined coal production related receivables		125.7		136.9		105.1		95.4
Deferred contract costs						65.4		102.0
Prepaid expenses		89.0		78.4		118.8		112.1

Total other current assets	$	679.6	$	633.7	$	997.3	$	1,113.9

The premium finance advances and loans represent short-term loans which we make to many of our brokerage related clients and other~~non-brokerage~~ non‑brokerage clients to finance their premiums paid to ~~insurance carriers.~~underwriting enterprises. These premium finance advances and loans are primarily generated by three Australian and New Zealand premium finance ~~subsidiaries.~~subsidiaries. Financing receivables are carried at amortized cost. Given that these receivables carry a fairly rapid delinquency period of only seven days post payment date, and that contractually the majority of the underlying insurance policies will be cancelled within one month of the payment due date in normal course, there historically has been a minimal risk of not receiving payment, and therefore we do not maintain any significant allowance for losses against this balance.

On June 13, 2017, we announced that we planned to close offerings of $648.0 million aggregate principal amount of private placement senior unsecured notes (both fixed and floating rate). We funded $250.0 million on June 27, 2017, $300.0 million on August 2, 2017 and $98.0 million on August 4, 2017, which was used in part to repay our $300.0 million August 3, 2017 debt maturity. The weighted average maturity of the $598.0 million of senior fixed rate notes is 11.6 years and their weighted average interest rate is 4.04% after giving effect to hedging gains. The interest rate on the $50.0 million of floating rate notes would be 3.02% using three-month LIBOR on October 24, 2017. In 2016 and 2017, we entered into~~pre-issuance~~ interest rate hedging transactions related to the $300.0 million August 3, 2017 maturity private placement. We realized a cash gain of approximately $8.3 million on the hedging transaction that will be recognized on a pro rata basis as a reduction in our reported interest expense over the life of the debt.

~~Earnings Per Share~~

8.Earnings Per Share

The following table sets forth the computation of basic and diluted net earnings per share (in millions, except per share data):

									Three-month period ended
	Three-month period ended September 30,				Nine-month period ended September 30,				March 31,
	2017		2016		2017		2016		2021		2020
Net earnings attributable to controlling interests	$	130.4	$	122.8	$	358.0	$	319.3	$	382.1	$	346.3

Weighted average number of common shares outstanding		180.5		177.6		179.8		177.4		194.6		188.7
Dilutive effect of stock options using the treasury stock method		2.0		0.9		1.8		0.8		4.5		4.5

Weighted average number of common and common equivalent shares outstanding		182.5		178.5		181.6		178.2		199.1		193.2

Basic net earnings per share	$	0.72	$	0.69	$	1.99	$	1.80	$	1.96	$	1.83

Diluted net earnings per share	$	0.71	$	0.69	$	1.97	$	1.79	$	1.92	$	1.79

~~Options to purchase 1.7~~Anti-dilutive stock-based awards of 0.4 million and ~~4.5~~0.3 million shares ~~of common stock~~ were outstanding at ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively, ~~but~~that were ~~not included~~excluded in the computation of the dilutive effect of ~~stock options~~stock-based awards for thethree-month periods then ended. Options to purchase 1.2 million and 5.8 million shares of common stock were outstanding at September 30, 2017 and 2016, respectively, but were not included in the computation of the dilutive effect of stock options for the~~nine-month~~ periods then ended. These ~~stock options~~stock‑based awards were excluded from the computation because the ~~options’~~ 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.

9. Stock Option Plans

~~Stock Option Plans~~

On May 16, 2017, our stockholders approved the Arthur J. Gallagher & Co. 2017 Long-Term Incentive Plan (which we refer to as the LTIP), which replaced our previous stockholder-approved Arthur J. Gallagher & Co. 2014 Long-Term Incentive ~~Plan.~~Plan (which we refer to as the 2014 LTIP). The LTIP term began May 16, 2017 and terminates on the date of the annual meeting of stockholders in 2027, unless terminated earlier by our board of directors. All of our officers, employees andnon-employee directors are eligible to receive awards under the LTIP. The compensation committee of our board of directors determines the ~~participants~~annual number of shares delivered under the LTIP. The LTIP provides fornon-qualified and incentive stock options, stock appreciation rights, restricted stock and restricted stock ~~units and performance~~ units, any or all of which may be made contingent upon the achievement of performance criteria. ~~Subject to the LTIP limits, the compensation committee has the discretionary authority to determine the size of an award.~~

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. 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.

~~- 18 -~~

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 ~~4.0~~1.8 million at September 30, 2017. To the extent necessary to be qualified performance-based compensation under Section 162(m) of the Internal Revenue Code (which we refer to as the IRC): (i) the maximum number of shares with respect to which options or stock appreciation rights or a combination thereof that may be granted during any calendar year to any person is 200,000; (ii) the maximum number of shares with respect to which awards other than options or stock appreciate rights that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code and are denominated in shares of common stock that may be earned pursuant to such awards granted during any calendar year to any person under the LTIP will be 200,000; and (iii) the maximum amount that may be payable with respect to all awards that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code and are denominated in cash granted during any calendar year to any person under the LTIP is $5.0 million.March 31, 2021.

The LTIP provides for the grant of stock options, which may be eithertax-qualified incentive stock options ornon-qualified options and stock appreciation rights. The compensation committee determines the period for the exercise of anon-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 anon-qualified stock option ortax-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 anet-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 arenon-transferable.

- 21 -

On March 16, ~~2017,~~2021, the compensation committee granted ~~1,650,400~~1,640,000 options under the ~~2014~~ 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 ~~2020, 2021~~2024, 2025 and ~~2022,~~2026, respectively. On March ~~17, 2016,~~12, 2020, the compensation committee granted ~~2,576,700~~1,590,740 options under the ~~2014~~ 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 ~~2019, 2020~~2023, 2024 and ~~2021,~~2025, respectively. The ~~2017~~2021 and ~~2016~~2020 options expire seven years from the date of grant, or earlier in the event of certain terminations of employment. For ~~certain of~~ our executive officers age 55 or older, stock options ~~awarded in 2017 and 2016~~ are ~~no longer~~not subject to forfeiture upon such officers’ departure from the company after two years from the date of grant.

During the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we recognized ~~$4.4~~ $3.7million and ~~$3.8 million, respectively, of compensation expense related to our stock option grants. During the nine-month periods ended September 30, 2017 and 2016, we recognized $12.9 million and $10.9~~$3.4 million, respectively, of compensation expense related to our stock option grants.

For purposes of expense recognition, 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:


	2017			2016			2021			2020
Expected dividend yield		2.8	%		3.0	%		1.5	%		2.1	%
Expected risk-free interest rate		2.3	%		1.6	%		0.9	%		0.7	%
Volatility		27.2	%		27.7	%		22.9	%		17.3	%
Expected life (in years)		5.0			5.5			5.4			5.4

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. Because our employee and director stock options have characteristics significantly different from those of traded options, and because changes in the selective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of our employee and~~non-employee~~ ~~director stock options.~~ The weighted average fair value per option for all options granted during the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, as determined on the grant date using the Black-Scholes option pricing model, was ~~$11.42~~$23.38 and ~~$8.45,~~$9.99, respectively.

~~Deferred Compensation~~

10. Deferred Compensation

We have a Deferred Equity Participation Plan (which we refer to as the DEPP), which is anon-qualified plan that generally provides for distributions to certain of our key executives when they reach age 62 (or theone-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.~~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 theone-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 prior to then. DEPP awards are generally made annually in the first quarter. In ~~the second quarter of 2016,~~addition, we ~~made~~annually make awards undersub-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 (includingsub-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.

~~- 20 -~~

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~~quarters of ~~each of 2017~~2021 and ~~2016,~~2020, the compensation committee approved ~~$14.0~~$17.0 million and ~~$10.1~~$14.1 million, respectively, of awards in the aggregate to certain key executives under the DEPP that were contributed to the rabbi trust in the first ~~quarter 2017~~quarters of 2021 and ~~2016,~~2020, 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 ~~2017~~2021 and ~~2016~~2020 awards. During the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we charged ~~$2.6~~$2.7 million and ~~$2.1~~$2.3 million, respectively, to compensation expense related to these awards. ~~During the nine-month periods ended September 30, 2017 and 2016, we charged $7.0 million and $5.5 million, respectively, to compensation expense related to these awards.~~

During the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we charged ~~$0.5~~$0.7 million and ~~$0.4 million, respectively, to compensation expense related to these awards. During thenine-month~~ ~~period ended September 30, 2017 and 2016, we charged $1.4 million and $0.8~~$0.7 million, respectively, to compensation expense related to these awards.

During the three-month period ended March 31, 2020, cash and equity awards with an aggregate fair value of $2.3 million 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 anon-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~~quarters of ~~each of 2017~~2021 and ~~2016,~~2020, the compensation committee approved ~~$5.1~~$7.2 million and ~~$3.1~~$3.0 million, respectively, of awards in the aggregate to certain key executives under the DCPP that were contributed to the rabbi trust in the second ~~quarter 2017~~quarters of 2021 and ~~2016,~~2020, respectively. During thethree-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we charged ~~$0.7~~$2.0 million and ~~$0.4 million, respectively, to compensation expense related to these awards. During thenine-month~~ ~~periods ended September 30, 2017 and 2016, we charged $1.8 million and $1.1~~$1.7 million, respectively, to compensation expense related to these awards.

~~Restricted Stock, Performance Share and Cash Awards~~

Restricted Stock Awards

As discussed in Note 89 to these unaudited consolidated financial statements, on May 16, 2017, our stockholders approved the LTIP, which replaced our previous stockholder-approved 2014 LTIP. The LTIP provides for the grant of a stock award either as restricted stock or as restricted stock ~~units.~~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 arenon-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.

~~- 21 -~~

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 ~~September 30, 2017, 4.0~~March 31, 2021, 1.8 million shares were available for grant under the LTIP for such awards.

In the first ~~quarter~~quarters of ~~each of 2017~~2021 and ~~2016,~~2020, we granted ~~477,500~~314,000 and ~~466,600~~405,900 restricted stock units, respectively, to employees under the LTIP, with an aggregate fair value of ~~$26.8~~$40.1 million and ~~$20.4~~$34.9 million, respectively, at the date of grant. These ~~2017~~2021 and ~~2016~~2020 awards of restricted stock units ~~vest as follows: 477,500 units granted in first quarter 2017 and 466,600 units granted in first quarter 2016,~~ vest in full based on continued employment through March 16, ~~2021~~2026 and March ~~11, 2020,~~12, 2025, respectively. For ~~certain of~~ our executive officers age 55 or older, restricted stock units ~~awarded in 2017 and 2016~~ are not subject to forfeiture upon such officers’ departure from the company after two years from the date of grant.

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 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 the ~~three-month~~three‑month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we recognized ~~$4.7~~$5.9 million and ~~$4.2~~$4.9 million, respectively, to compensation expense related to restricted stock unit awards granted in ~~2007~~2015 through 2017. During the nine-month periods ended September 30, 2017 and 2016, we recognized $15.2 million and $14.2 million, respectively, to compensation expense related to restricted stock unit awards granted in 2007 through 2017.2021. The total intrinsic value of unvested restricted stock units at ~~September 30, 2017~~March 31, 2021 and ~~2016~~2020 was ~~$107.6~~$212.8 million and ~~$79.7~~$135.0 million, respectively.

The Program consists of aone-year performance period based on our financial performance and a~~two-year~~three-year vesting ~~period.~~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 EBITAC 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 for the ~~2017~~2021 provisional award will fully vest based on continuous employment through January 1, ~~2020.~~2024. The ultimate award value will be equal to the trailing twelve-month price of our common stock on December 31, ~~2019,~~2023, 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 in ~~2020.~~2024. If an eligible employee leaves us prior to the vesting date, the entire award will be forfeited.

~~12.~~

~~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 ~~two~~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 ~~two~~three years into the future.

We have not received or pledged any collateral related to derivative arrangements at ~~September 30, 2017.~~March 31, 2021.

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. ~~Outstanding purchase commitments in the table above include $0.7 million related to expenditures on our new corporate headquarters.~~

Note Purchase Agreements, Credit Agreement and Premium Financing Debt Facility -See Note 67 to ~~our~~these unaudited consolidated financial statements for a summary of the amounts outstanding under the 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 will accommodate approximately 2,000 employees at peak capacity. Our prior headquarters was located at Two Pierce Place, Itasca, Illinois, where we lease approximately 306,000 square feet of space, or approximately 60% of the building. The lease commitment on the Itasca property expires February 28, 2018.

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.

We have leased certain office space to severalnon-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 ~~September 30, 2017.~~March 31, 2021.

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~~Off‑Balance Sheet Debt section below for a discussion of our 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.

Since January 1, 2002, we have acquired ~~450~~589 companies, all of which were accounted for using the acquisition method for recording business combinations. Substantially all of the purchase agreements related to these acquisitions contain provisions for potential earnout obligations. For all of our acquisitions made in the period from ~~2014~~2017 to ~~2017~~2021 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 atwo- to three-year period subsequent to the acquisition date. The aggregate amount of the maximum earnout obligations related to these acquisitions was ~~$563.9~~$1,146.1 million, of which ~~$274.3~~$623.0 million was recorded in our consolidated balance sheet as of ~~September 30, 2017~~March 31, 2021 based on the estimated fair value of the expected future payments to be ~~made.~~made, of which approximately $518.2 million can be settled in cash or stock at our option and $104.8 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 ~~September 30, 2017~~March 31, 2021 or December 31, ~~2016~~2020, that was recourse to ~~us.~~us.

Litigation, Regulatory and Taxation Matters - We are a defendant in various legal actions incidental to the nature of our business including but not limited to matters related to employment practices, alleged breaches of~~non-compete~~ non‑compete or other restrictive covenants, theft of trade secrets, breaches of fiduciary duties and related causes of action. We are also periodically the subject of inquiries, investigations and reviews by regulatory and taxing authorities into various matters related to our business, including our operational, compliance and finance functions. Neither the outcomes of these matters nor their effect upon our business, financial condition or results of operations can be determined at this time.

~~Our micro-captive~~As previously disclosed, our IRC 831(b) (or “micro-captive”) advisory services ~~are~~businesses has been under investigation by the ~~Internal Revenue Service (IRS). Additionally, the~~ IRS ~~has initiated audits for the 2012 tax year of over 100 of the micro-captive insurance companies organized and/or managed by us.~~since 2013.

In May 2020, we learned that the Department of Justice (DOJ) began conducting a criminal investigation related to IRC 831(b) micro-captive underwriting enterprises. We have been advised that we are not ~~meet~~currently a target of the ~~requirements of IRC Section 831(b),~~investigation. In June 2020 our subsidiary Artex Risk Solutions, Inc. (which we ~~could be held liable~~refer to ~~pay monetary claims by~~as Artex) received a grand jury subpoena requesting documents relating to its micro‑captive advisory business. We have produced documents in response to the subpoena. We are fully cooperating with both the IRS ~~and/or our micro-captive clients,~~investigation and ~~our future earnings from our micro-captive operations could be materially adversely affected, any of which events, could negatively impact~~ the overall captive business and adversely affect our consolidated results of operations and financial condition. Due to the fact that the IRS has not made any allegation against us or completed its audits of our clients, weDOJ investigation. We are not able to reasonably estimate the amount of any potential loss in connection with these investigations.

On December 7, 2018, a class action lawsuit was filed against us, Artex and other defendants, in the United States District Court for the District of Arizona. The named plaintiffs are micro-captives and related entities and owners who had IRC Section 831(b) tax benefits disallowed by the IRS. The complaint alleges that the defendants defrauded the plaintiffs by marketing and managing micro-captives with the knowledge that the captives did not constitute bona fide insurance and thus would not qualify for tax benefits. The complaint does not specify the amount of damages sought by the named plaintiffs. On August 5, 2019, the trial court granted the defendants’ motion to compel arbitration and dismissed the class action lawsuit. Plaintiffs appealed this ~~investigation.~~ruling to the United States Court of Appeals for the Ninth Circuit. On September 9, 2020, the Ninth Circuit Court affirmed the ruling of the trial court dismissing the class action lawsuit. On March 17, 2021, plaintiffs filed a petition for writ of certiorari with the United States Supreme Court. We will continue to defend against the lawsuit vigorously. Litigation is inherently uncertain, however, and it is not possible for us to predict the ultimate outcome of this matter and the financial impact to us, nor are we able to reasonably estimate the amount of any potential loss in connection with this lawsuit.

Contingent Liabilities -We purchase insurance to provide protection from errors and omissions (which we refer to as E&O) claims that may arise during the ordinary course of business. ~~We currently~~Currently we retain the first ~~$5.0~~$10.0 million of ~~each and~~ every E&O ~~claim. Our E&O insurance provides aggregate coverage for E&O losses~~claim up to ~~$175.0~~$10.0 million. In addition, we retain, in aggregate: up to another $4.5 million ~~in excess of our retained amounts.~~between $10.0 million and $100.0 million, plus up to another $20.0 million between $100.0 million and $240.0 million, and up to another $27.0 million between $240.0 million and $350.0 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 ~~September 30, 2017 unaudited~~March 31, 2021 consolidated balance sheet is above the lower end of the most recently determined actuarial range by ~~$1.5~~$3.0 million and below the upper end of the actuarial range by ~~$7.2~~$6.1 million. In addition to this E&O reserve, in the three-month period ended March 31, 2021, we established provisions for potential unusual pandemic related claim defense and other costs. 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.~~herein.

Tax-advantaged Investments No Longer Held -Between 1996 and 2007, we developed and then sold portions of our ownership in various energy related investments, many of which qualified for tax credits under IRC Section 29. We recorded tax benefits in connection with our ownership in these investments. At ~~September 30, 2017,~~March 31, 2021, we had exposure on ~~$108.2~~$108.0 million of previously earned tax credits. Under the TCJA, a portion of these previously earned tax credits were refunded in 2019 for tax year 2018, according to a specific formula. Under the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act), which was passed on March 27, 2020, we accelerated the refund of all remaining credits on April 17, 2020, and the remaining credits were refunded to us in the second quarter of 2020. In 2004, 2007 and 2009, the IRS examined several of these investments and all examinations were closed without any changes being proposed by the IRS. However, any future adverse tax audits, administrative rulings or judicial decisions could disallow previously claimed tax ~~credits. Because of~~credits.

Due to the contingent nature of this exposure and our related assessment of its likelihood, no reserve has been recorded in our ~~September 30, 2017~~March 31, 2021 consolidated balance sheet related to this exposure.

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 with the match paid 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 company stock. We expensed (net of plan forfeitures) $17.3 million and $15.6 million related to the plan in the three-month periods ended March 31, 2021 and 2020, respectively. Our board of directors authorized the use of common stock to fund our 2020 employer matching contributions to the 401(k) plan, which we funded in February 2021.

17.Segment Information

~~15.~~

~~Segment Information~~

We have ~~three~~3 reportable segments: brokerage, risk management and corporate.

The brokerage segment is primarily comprised of our retail and wholesale insurance brokerage operations. The brokerage segment generates revenues through commissions paid by ~~insurance underwriters~~underwriting enterprises and through fees charged to our clients. Our brokers, agents and administrators act as intermediaries between ~~insurers~~underwriting enterprises and ~~their customers~~our clients and we do not ~~generally~~ assume net underwriting risks.

The risk management segment provides contract claim settlement and administration services for enterprises and public entities that choose to self-insure some or all of their property/casualty coverages and for ~~insurance companies~~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 negotiatedper-claim orper-service fee basis. Our risk management segment also provides risk management consulting services that are recognized as the services are delivered.

The corporate segment managesour clean energy and other investments. In addition, the corporate segment reports the financial information related to our debt and ~~certain~~other corporate costs, external acquisition-related expenses and ~~acquisition-related activities.~~the impact of foreign currency translation.

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.

~~Review by Independent Registered Public Accounting Firm~~

The interim consolidated financial statements at September 30, 2017 and for the three-month and nine-month periods ended September 30, 2017 and 2016 have been reviewed by Ernst & Young LLP, our independent registered public accounting firm, and their report is included herein.

~~Review Report of Independent Registered Public Accounting Firm~~

~~Board of Directors and Stockholders~~

~~Arthur J. Gallagher & Co.~~

We have reviewed the consolidated balance sheet of Arthur J. Gallagher & Co. as of September 30, 2017, and the related consolidated statements of earnings and comprehensive earnings for the three-month and nine-month periods ended September 30, 2017 and 2016, the consolidated statement of cash flows for the nine-month periods ended September 30, 2017 and 2016, and the consolidated statement of stockholders’ equity for the nine-month period ended September 30, 2017. These financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Arthur J. Gallagher & Co. as of December 31, 2016, and the related consolidated statements of earnings, comprehensive earnings, stockholders’ equity, and cash flows for the year then ended, not presented herein, and we expressed an unqualified audit opinion on those consolidated financial statements in our report dated February 10, 2017. In our opinion, the accompanying consolidated balance sheet of Arthur J. Gallagher & Co. as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

~~Management’s Discussion and Analysis of Financial Condition and Results of Operations~~

The discussion and analysis that follows relates to our financial condition and results of operations for the ~~nine-month period~~three-month periods ended ~~September 30, 2017.~~March 31, 2021 and 2020. Readers should review this information in conjunction with the March 31, 2021 unaudited consolidated financial statements and notes included in Item 1 of Part I of this quarterly report onForm ~~10-Q~~10‑Q and the audited consolidated financial statements and notes, and Management’s Discussion and Analysis of Financial Condition and Results of Operations, contained in our annual report onForm 10-K for the year ending December 31, ~~2016.~~2020.

Prior Year Discussion of Results and Comparisons

For Information ~~Concerning Forward-Looking Statements~~

~~This report contains certain statements related to future~~on fiscal first quarter 2020 results ~~or states our intentions, beliefs~~ and ~~expectations or predictions for the future, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act~~similar comparisons, see “Item 7. Management’s Discussion and Analysis of ~~1995. Forward-looking statements relate to expectations or forecasts~~Financial Condition and Results of future events. Such statements use words such as “anticipate,” “believe,” “estimate,” “expect,” “contemplate,” “forecast,” “project,” “intend,” “plan,” “potential,” and other similar terms, and future or conditional tense verbs like “could,” “may,” “might,” “see,” “should,” “will” and “would.” You can also identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. For example, we may use forward-looking statements when addressing topics such as: market and industry conditions, including competitive and pricing trends; acquisition strategy; the expected impact of acquisitions and dispositions; the development and performanceOperations” of our services and products; changes in the composition or level of our revenues or earnings; our cost structure and the outcome of cost-saving or restructuring initiatives; future capital expenditures; future debt levels and anticipated actions to be taken in connection with maturing debt; future debt to earnings ratios; the outcome of contingencies; dividend policy; pension obligations; cash flow and liquidity; capital structure and financial losses; future actions by regulators; the outcome of existing regulatory actions, investigations, reviews or litigation; the impact of changes in accounting rules; financial markets; interest rates; foreign exchange rates; matters relating to our operations; income taxes; expectations regarding our investments, including our clean energy investments; and integrating recent acquisitions. These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from either historical or anticipated results depending on a variety of factors.

~~Potential factors that could impact results include:~~

~~Failure to successfully and cost-effectively integrate recently acquired businesses and their operations or fully realize synergies from such acquisitions in the expected time frame;~~

~~Volatility or declines in premiums or other adverse trends in the insurance industry;~~

~~An economic downturn;~~

~~Competitive pressures in each of our businesses;~~

Risks that could negatively affect the success of our acquisition strategy, including continuing consolidation in our industry and growing interest in acquiring insurance brokers on the part of private equity firms, which could make it more difficult to identify targets and could make them more expensive, the risk that we may not receive timely regulatory approval of desired transactions, execution risks, integration risks, the risk of post-acquisition deterioration leading to intangible asset impairment charges, and the risk we could incur or assume unanticipated regulatory liabilities such as those relating to violations of anti-corruption and sanctions laws;

~~Our failure to attract and retain experienced and qualified personnel;~~

Risks arising from our international operations, including the risks posed by political and economic uncertainty in certain countries (such as the risks posed by Brexit), risks related to maintaining regulatory and legal compliance across multiple jurisdictions (such as those relating to violations of anti-corruption, sanctions and privacy laws), and risks arising from the complexity of managing businesses across different time zones, geographies, cultures and legal regimes;

~~Risks particular to our risk management segment, including any slowing of the trend toward outsourcing claims administration, and of the concentration of large amounts of revenue with certain clients;~~

~~The lower level of predictability inherent in contingent and supplemental commissions versus standard commissions;~~

~~Sustained increases in the cost of employee benefits;~~

~~- 31 -~~

Our inability to recover successfully, including damage to our reputation and client relationships, should we experience a disaster, cybersecurity attack or other significant disruption to business continuity;

~~Damage to our reputation;~~

Our failure to comply with regulatory requirements, including those related to governance and control requirements in particular jurisdictions, international sanctions, or a change in regulations or enforcement policies that adversely affects our operations (for example, relating to insurance broker compensation methods or the failure of state and local governments to follow through on agreed-upon income tax credits or other tax related incentives, relating to our corporate headquarters);

Violations or alleged violations of the U.S. Foreign Corrupt Practices Act (FCPA), the U.K. Bribery Act 2010 or other anti-corruption laws and Foreign Account Tax Compliance provisions of the Hiring Incentives to Restore Employment Act, (which we refer to as FATCA);

~~The outcome of any existing or future investigation, review, regulatory action or litigation;~~

Our failure to adapt our services to changes resulting from the Patient Protection and Affordable Care Act and the Health Care and Education Affordability Reconciliation Act and any changes in such laws brought about by the current administration;

~~Unfavorable determinations related to contingencies and legal proceedings;~~

~~Improper disclosure of confidential, personal or proprietary data;~~

~~Significant changes in foreign exchange rates;~~

~~Changes to our financial presentation from new accounting estimates and assumptions (including as a result of the new lease and revenue recognition standards);~~

Risks related to our clean energy investments, including the risk of intellectual property claims, utilities switching from coal to natural gas, environmental and product liability claims, and environmental compliance costs;

~~Disallowance of Internal Revenue Code of 1986, as amended, (which we refer to as IRC) Section 29 or IRC Section 45 tax credits for us or our partners;~~

~~The risk that our outstanding debt adversely affects our financial flexibility and restrictions and limitations in the agreements and instruments governing our debt;~~

~~The risk we may not be able to receive dividends or other distributions from subsidiaries;~~

~~The risk of share ownership dilution when we issue common stock as consideration for acquisitions and for other reasons; and~~

~~Volatility of the price of our common stock.~~

Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of, and are based on information available to us on, the date of the applicable document. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to update any such statements or release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events.

Forward-looking statements are not guarantees of future performance. They involve risks, uncertainties and assumptions, including the risk factors referred to above. Our future performance and actual results may differ materially from those expressed in forward-looking statements. Many of the factors that will determine these results are beyond our ability to control or predict. Forward-looking statements speak only as of the date that they are made, and we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

A detailed discussion of the factors that could cause actual results to differ materially from our published expectations is contained under the heading “Risk Factors” in our filings with the Securities and Exchange Commission, including our Annual Report onForm ~~10-K~~10-Q for the fiscal ~~year~~three-month period ended ~~December~~March 31, ~~2016, and any other reports we file with the SEC in the future.~~2020.

Information RegardingNon-GAAP Measures and Other

In the discussion and analysis of our results of operations that follows, in addition to reporting financial results in accordance with GAAP, we provide information regarding EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin, diluted net earnings per share, as adjusted (adjusted EPS) ~~for the brokerage and risk management segments,~~ ,adjusted revenues, adjusted compensation and operating expenses, adjusted compensation expense ratio, adjusted operating expense ratio and organic ~~revenue measures for each operating segment.~~revenue. These measures are not in accordance with, or an alternative to, the GAAP information provided in this quarterly report onForm ~~10-Q.~~10‑Q. We believe that these presentations provide useful information to management, analysts and investors regarding financial and business trends relating to our results of operations and financial ~~condition.~~condition because they provide investors with measures that our chief operating decision maker uses when reviewing the company’s performance, and for the other reasons described below. Our industry peers may provide similar supplementalnon-GAAP information with respect to one or more of these measures, although they may not use the same or comparable terminology and may not make identical adjustments. Thenon-GAAP information we provide should be used in addition to, but not as a substitute for, the GAAP information provided. ~~As disclosed in our most recent Proxy Statement, beginning in first quarter 2017, we~~We make determinations regarding certain elements of executive officer incentive compensation, performance share awards and annual cash incentive awards, partly on the basis of measures related to adjusted EBITDAC. ~~Certain reclassifications have been made to the prior-year amounts reported in this quarterly report onForm 10-Q~~ ~~in order to conform them to the current-year presentation.~~

AdjustedNon-GAAP presentation- We believe that the adjusted~~Non-GAAP~~ ~~presentations~~ non-GAAP presentation of the current and prior ~~year~~period information presented on the following pages provides stockholders and other interested persons with useful information regarding certain financial metrics that may assist such persons in analyzing our operating results as they develop a future earnings outlook for us. Theafter-tax amounts related to the adjustments were computed using the normalized effective tax rate for each respective period.

•

Adjusted measures - We define these measures as revenues (for the brokerage segment), revenues before reimbursements (for the risk management segment), net earnings, compensation expense and operating expense, respectively, each adjusted to exclude the following, as applicable:

•

Net losses or gain on divestitures, which are primarily net losses or proceeds received related to sales of books of business and other divestiture transactions, such as the disposal of a business through sale or closure.

•

Acquisition integration costs, which include costs related to certain of our large acquisitions, outside the scope of our usual tuck-in strategy, not expected to occur on an ongoing basis in the future once we fully assimilate the applicable acquisition. These costs are typically associated with redundant workforce, extra lease space, duplicate services and external costs incurred to assimilate the acquisition with our IT related systems.

•

Workforce related charges, which primarily include severance costs (either accrued or paid) related to employee terminations and other costs associated with redundant workforce.

•

Lease termination related charges, which primarily include costs related to terminations of real estate leases and abandonment of leased space.

•

Acquisition related adjustments, which include change in estimated acquisition earnout payables adjustments, impairment charges and acquisition related compensation charges.

~~Adjusted revenues and expenses -~~~~We define these measures as revenues, compensation expense and operating expense, respectively, each adjusted to exclude the following:~~

•

The impact of foreign currency translation, as applicable. The amounts excluded with respect to foreign currency translation are calculated by applying current year foreign exchange rates to the same period in the prior year.

•

Adjusted ratios- Adjusted compensation expense and adjusted operating expense, respectively, each divided by adjusted revenues.

Non-GAAP Earnings Measures

We believe that the presentation of EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin and adjusted EPS for the brokerage and risk management segment, each as defined below, provides a meaningful representation of our operating performance. Adjusted EPS is a performance measure and should not be used as a measure of our liquidity. We also consider EBITDAC and EBITDAC margin as ways to measure financial performance on an ongoing basis. In addition, adjusted EBITDAC, adjusted EBITDAC marginand adjusted EPS for the brokerage and risk management segments are presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

~~EBITDAC~~~~and EBITDAC Margin~~- ~~EBITDAC is net earnings before interest, income taxes, depreciation, amortization and the change in estimated acquisition earnout payables and EBITDAC margin is EBITDAC divided by total revenues.~~

•

EBITDACand EBITDAC Margin- EBITDAC is net earnings before interest, income taxes, depreciation, amortization and the change in estimated acquisition earnout payables and EBITDAC margin is EBITDAC divided by total revenues (for the brokerage segment) and revenues before reimbursements (for the risk management segment). These measures for the brokerage and risk management segments provide a meaningful representation of our operating performance ~~and,~~ for the overall business and provide a meaningful way to measure its financial performance on an ongoing basis.

•

Adjusted EBITDAC and Adjusted EBITDAC Margin - Adjusted EBITDAC is EBITDAC adjusted to exclude net gains on divestitures, acquisition integration costs, workforce related charges, lease termination related charges, acquisition related adjustments, and the period-over-period impact of foreign currency translation, as applicable, and Adjusted EBITDAC margin is Adjusted EBITDAC divided by total adjusted revenues (defined above).These measures for the brokerage and risk management segments provide a meaningful representation of our operating performance and, are also presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

•

Adjusted EPS and Adjusted Net Earnings - Adjusted net earnings have been adjusted to exclude the after-tax impact of net gains on divestitures, acquisition integration costs, the impact of foreign currency translation, workforce related charges, lease termination related charges, acquisition related adjustments and effective income tax rate impact, as applicable. Adjusted EPS is Adjusted Net Earnings divided by diluted weighted average shares outstanding. This measure provides a meaningful representation of our operating performance (and as such should not be used as a measure of our liquidity), and for the overall business is also presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

~~Adjusted EBITDAC and Adjusted EBITDAC Margin -~~Adjusted EBITDAC is EBITDAC adjusted to exclude gains realized from sales of books of business, acquisition integration costs, workforce related charges, lease termination related charges, acquisition related adjustments, and the period-over-period impact of foreign currency translation, as applicable and Adjusted EBITDAC margin is Adjusted EBITDAC divided by total adjusted revenues (defined above).These measures for the brokerage and risk management segments provide a meaningful representation of our operating performance and, are also presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

~~Adjusted EPS for the Brokerage and Risk Management segments -~~~~We define this measure as net earnings adjusted to exclude theafter-tax~~ impact of gains realized from sales of books of business, acquisition integration costs, workforce related charges, lease termination related charges and acquisition related adjustments, the period-over-period impact of foreign currency translation, as applicable, divided by diluted weighted average shares outstanding. This measure provides a meaningful representation of our operating performance (and as such should not be used as a measure of our liquidity), and is also presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

Organic Revenues (anon-GAAP measure)- For the brokerage segment, organic change in base commission and fee revenues, ~~excludes~~supplemental revenues and contingent revenues exclude the first twelve months of ~~net commission and fee~~such revenues generated from acquisitions and ~~the net commission and fee~~ such revenues related to divested operations ~~disposed of~~ in each year presented. These ~~commissions and fees~~revenues are excluded from organic revenues in order to help interested persons analyze the revenue growth associated with the operations that were a part of our business in both the current and prior ~~year.~~period.

For the risk management segment, organic change in fee revenues excludes the first twelve months of fee revenues generated from acquisitions ~~and the fee revenues related to operations disposed of~~ in each year presented. In addition, change in organic growth excludes the period-over-period impact of foreign currency translation to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of ~~variability or are due to the limited-time nature of these revenue sources.~~variability.

These revenue items are excluded from organic revenues in order to determine a comparable, butnon-GAAP, measurement of revenue growth that is associated with the revenue sources that are expected to continue in the current year and beyond. We have historically viewed organic revenue growth as an important indicator when assessing and evaluating the performance of our brokerage and risk management segments. We also believe that using this~~non-GAAP~~ non‑GAAP measure allows readers of our financial statements to measure, analyze and compare the growth from our brokerage and risk management segments in a meaningful and consistent manner.

Reconciliation ofNon-GAAP Information Presented to GAAP Measures- This quarterly report onForm ~~10-Q~~10‑Q includes tabular reconciliations to the most comparable GAAP measures, as follows: for EBITDAC (on pages 44 and 50), for adjusted revenues, adjusted ~~compensation expense~~EBITDAC and adjusted ~~operating expense, EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin,~~ diluted net earnings per share ~~(as adjusted) and~~(on page 39), for organic revenue ~~measures.~~measures (on pages 45 and 50), respectively, for the brokerage and risk management segments), for adjusted EBITDAC margin, adjusted compensation expense and operating expenses, (on pages 44, 46 and 47, respectively, for the brokerage segment and on pages 50 and 51, respectively, for the risk management segment).

Other Information- 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 local statutory rates. As a result, the provision for income taxes for the corporate segment reflects the entire benefit to us of the IRC Section 45 tax credits produced, because that is the segment which generated the credits. The law that provides for IRC Section 45 tax credits ~~substantially expires~~expired in December 2019 for our fourteen plants placed in service prior to December 31, 2009 (which we refer to as the 2009 Era ~~Plants~~Plants) and will expire in December 2021 for our ~~twenty~~twenty-one plants placed in service prior to December 31, 2011 (which we refer to as the 2011 Era ~~Plants.~~Plants). We anticipate reporting an effective tax rate of approximately ~~34.0%~~23.0% to ~~36.0%~~25.0% in the brokerage segment and ~~36.0%~~24.0% to ~~38.0%~~26.0% in the risk management segment for the foreseeable future. Reported operating results by segment would change if different allocation methods were applied. When the law governing IRC Section 45 tax credits expires, reported GAAP revenues and net earnings will decrease, yet our net cash flow will increase as a result of not having to pay expenses to operate the clean coal facilities and also from an increase in the use of credits against our U.S. federal income tax obligations.

In the discussion that follows regarding our results of operations, we also provide the following ratios with respect to our operating results: pretax profit margin, compensation expense ratio and operating expense ratio. Pretax profit margin represents pretax earnings divided by total revenues. The compensation expense ratio is compensation expense divided by total revenues. The operating expense ratio is operating expense divided by total revenues.

Overview and ~~Third~~First Quarter ~~2017~~2021 Highlights

We are engaged in providing insurance brokerage and consulting services, and third-party property/casualty claims settlement and administration services to entities in the U.S. and abroad. In the ~~nine-month~~three-month period ended ~~September 30, 2017,~~March 31, 2021, we generated approximately ~~70%~~71% of our revenues for the combined brokerage and risk management segments domestically and ~~30%~~29% internationally, primarily in Australia, Bermuda, Canada, the Caribbean, New Zealand and the U.K. We have three reportable segments: brokerage, risk management and corporate, which contributed approximately ~~62%~~74%, ~~13%~~12% and ~~25%~~14%, respectively, to revenues during the~~nine-month~~ three‑month period ended ~~September 30, 2017.~~March 31, 2021. Our major sources of operating revenues are commissions, fees and supplemental and contingent ~~commissions~~revenues from brokerage operations and fees from risk management operations. Investment income is generated from invested cash and fiduciary funds, clean energy and other investments, and interest income from premium financing.

We typically cite the Council of Insurance Agents and Brokers (which we refer to as CIAB) insurance pricing quarterly survey at this time as an indicator of the current insurance rate ~~environment, but the third~~environment. The first quarter ~~2017~~2021 survey had not been published as of the filing date of this report. ~~We anticipate that the trends noted in the second~~The fourth quarter ~~2017 survey will likely be similar to what will be reported for third quarter 2017. The second quarter 2017 CIAB~~2020 survey indicated that commercial property/casualty rates ~~decreased~~increased by ~~2.8%,~~10.7% on ~~average, across all~~average. We expect a similar trend to be noted when the CIAB first quarter 2021 survey report is issued, which would indicate overall continued price firming and hardening in some lines. The ~~first quarter 2017~~ CIAB ~~survey indicated that~~represents the leading domestic and international insurance brokers, who write approximately 85% of the commercial property/casualty ~~rates decreased by 2.5%, on average, across all lines. In 2017, while we see retail~~premiums in the U.S.

We believe increases in property/casualty rates will continue for the remainder of 2021; however, loss trends could deteriorate over the next year, leading to a more difficult rate and conditions environment in certain lines. The economies of the U.S. and other countries around the world contracted during 2020 as a ~~headwind,~~result of COVID-19, and while first quarter 2021 economic activity improved relative to the last three quarters of 2020, activity has yet to rebound to pre-pandemic levels. The improving level of economic activity is leading to, and is likely to continue to lead to, higher exposure units and lower unemployment. Additionally, we do see property/casualty exposure growth offsetting this partially. We also see employment growth along with complexity and uncertainty surrounding the Affordable Care Act as tailwinds for our employee benefit units. In addition,expect that our history of strong new business generation, solid retentions and enhanced value-added services for our carrier partners should all result in further organic growth opportunities around the world. ~~Internationally, we see a similar property/casualty market in U.K. retail and Canada, more softening in London Specialty, but an improving market in Australia and New Zealand.~~ Overall, we believe that in a ~~modestly-down~~positive rate environment ~~can be partially mitigated through~~with growing exposure ~~unit growth in certain lines and by~~units, our professionals ~~demonstrating our~~can demonstrate their expertise and ~~high quality value added~~high-quality, value-added capabilities by strengthening our clients’ insurance ~~portfolio in these times.~~portfolios and delivering insurance and risk management solutions within our clients’ budget. Based on our experience, there is adequate capacity in the insurance market for most lines of coverage, terms and conditions are tightening, most insurance carriers appear to be making rational pricing ~~decisions. In lines~~decisions and accounts where rate increases or decreases are warranted, the underwriters are pricing accordingly. As carriers reach their profitability targets in lines, rates may start to flatten. In summary, in this environment, rate decreased at a moderate pace, clients can broadly still obtain coverage, businesses continue to stay in standard-line markets and there is adequate capacity in the insurance market. It is not clear whether the rate retraction will continue due to uncertainty of the current economic environment. The CIAB represents the leading domestic and international insurance brokers, who write approximately 85% of the commercial property/casualty premiums in the U.S.

~~Accounting Changes~~

Note 2 to our consolidated financial statements included in this report contains information regarding the potential impact a new revenue recognition accounting standard could have on our future financial presentation. This new standard will be effective for us in first quarter 2018. While we do not believe adoption of the new standard will have a material impact on the presentation of our consolidated results of operations on an annual basis, there could be a material impact on the presentation of our results in certain quarters due to timing changes in the recognition of certain revenue and expenses. As a result, we may experience a different “seasonality” in our quarterly results after adoption of the new standard, with a shift in the timing of revenue recognized from the second, third and fourth quarterscoverage. Please also refer to the ~~first quarter.~~section entitled “COVID-19 Impact” below on page 41.

In our corporate segment, netafter-tax earnings from our clean energy investments were ~~$38.3~~$33.4 million and ~~$88.2~~$52.5 million, ~~in thethree-month~~ ~~andnine-month~~ ~~periods ended September 30, 2017, respectively. Net after tax earnings from our clean energy investments were $39.3 million and $85.8 million~~as reported, in the three-month ~~and nine-month~~ periods ended ~~September 30, 2016.~~March 31, 2021 and 2020, respectively. We anticipate our clean energy investments to generate between ~~$123.0~~$70.0 million and ~~$129.0~~$80.0 million in adjusted net earnings in ~~2017.~~2021. See “COVID-19 Impact” on page 41. We expect to use the additional cash flow generated by these earnings to continue our mergers and acquisition strategy in our core brokerage and risk management operations.

The following provides information that management believes is helpful when comparing revenues before reimbursements, net earnings, EBITDAC and diluted net earnings per share for the three-month period ended ~~September 30, 2017~~March 31, 2021 with the same period in ~~2016.~~2020.

COVID-19 Impact

In our property/casualty brokerage operations, during first quarter 2021 (a) our customer retention and new business generation remained similar to pre-pandemic levels, (b) renewal exposure units (i.e., insured values, payrolls, employees, miles driven, etc.) were lower than pre-pandemic first quarter 2020, but higher than the last three quarters of 2020, (c) premium rates across most geographies and lines of coverage have continued to increase, effectively mitigating exposure unit declines, and (d) mid-term policy modifications (including cancellations) were a net positive, similar to first quarter 2020.

Thus far in second quarter 2021, property/casualty new business, retentions and mid-term policy modifications are trending similar to first quarter 2021 and much improved compared to lows seen in April and May 2020, as our customers’ businesses continue to recover and economic activity increases. So far during second quarter 2021, we continue to see overall property/casualty premium rates move higher and exposure units also trended higher than first quarter 2021.

In our employee benefits brokerage operations, during first quarter 2021 (a) we saw a slight improvement in covered lives on renewal business compared to fourth quarter 2020, yet still lower than pre-pandemic levels, and (b) new consulting and special project work was also lower than pre-pandemic levels. So far during second quarter 2021, we are seeing a modest increase in covered lives, consulting engagements and special project work compared to first quarter 2021. We believe these favorable trends should continue for the remainder of 2021; however, if the economic recovery slows or reverses course, we could see our benefits revenue soften from current levels.

In our risk management operations, first quarter 2021 new claims arising were consistent with fourth quarter 2020, but still below pre‑pandemic first quarter 2020 levels. So far during second quarter 2021, we are seeing new claims arising similar to first quarter 2021, which is a substantial increase compared to lows seen in April and May 2020. A slower recovery or reversal in the number of workers employed could cause fewer claims to arise in future quarters.

Our clean energy investments saw higher electricity production in first quarter 2021 compared to first quarter 2020 due to colder temperatures, rising natural gas prices and more plants within our portfolio being operational during the period. First quarter 2021 production was only slightly lower than pre-pandemic production levels seen in first quarter 2019. However, lower overall demand for energy caused by the pandemic and more supply from renewables may cause lower production by the plants within our portfolio for the remainder of 2021.

Of our nearly 1,000 office locations, more than 400 are open, but most at reduced capacity. Accordingly the vast majority of our employees continue to work remotely for some or all of their work week. We believe our service levels are unchanged from pre‑pandemic levels. We have not had any office-wide outbreaks of COVID-19, and there have been approximately 450 confirmed cases among approximately 34,000 employees - all of which we believe contracted the virus outside of our office locations.

Given the deterioration in economic conditions since first quarter 2020, we are actively managing costs by limiting discretionary spending such as travel, entertainment and advertising expenses, adjusting our real estate footprint, reducing capital expenditures, limiting use of outside labor and consultants, increasing utilization of our centers of excellence, and in mid-2020 we adjusted portions of our workforce where business had declined significantly and normal attrition was not sufficient.

During first quarter 2021, the cost saving impact of these actions totaled approximately $64 million compared to pre-pandemic first quarter 2020, adjusted for pro forma full-quarter costs related to acquisitions. These cost savings were consistent with savings realized in second, third and fourth quarter 2020. Offsetting these savings were severance and lease termination costs related to these actions. Thus far during second quarter 2021, we are holding most of our prior year cost savings.

We have $1.6 billion of available liquidity; however, a return to mid-2020 pandemic economic conditions may cause our liquidity position to deteriorate.

Update on Ransomware Incident

As previously disclosed, on September 26, 2020, we detected a ransomware incident impacting our internal systems. We implemented our incident response plan, took our global systems offline, isolated impacted systems, retained cyber security counsel and forensic experts and reported the event to the FBI. The incident was contained, and all critical systems were back in service quickly following the incident.

While we are unaware of any actual or attempted misuse of information, our investigation into the incident remains ongoing. Based on the results of the forensic investigation to date, we do not believe this incident will have a material adverse effect on our business, operations or financial condition.

- 41 -

We maintain cyber liability insurance coverage, but disputes over the extent of insurance coverage for claims are not uncommon. Furthermore, while we have not been the subject of any legal proceedings involving this incident, it is possible we could be the subject of claims from persons alleging they suffered damages from the incident, or actions by governmental authorities.

Results of Operations

Brokerage

The brokerage segment accounted for ~~62%~~74% of our revenues during the ~~nine-month~~three-month period ended ~~September 30, 2017.~~March 31, 2021. Our brokerage segment is primarily comprised of retail and wholesale brokerage operations. Our ~~retail~~ brokerage ~~operations negotiate and place property/casualty,employer-provided~~ ~~health and welfare insurance and retirement solutions, principally for middle-market commercial, industrial, public entity, religious andnot-for-profit~~ ~~entities. Many~~segment generates revenues by:

(i)

Identifying, negotiating and placing all forms of insurance or reinsurance coverage, as well as providing 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)

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.

(iii)

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.

(iv)

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 primary source of our retail brokerage customers choose to place their insurance with insurance underwriters, while others choose to use alternative vehicles such as self-insurance pools, risk retention groups or captive insurance companies. Our wholesale brokerage operations assist our brokers and other unaffiliated brokers and agents in the placement of specialized, unique and~~hard-to-place~~ ~~insurance programs.~~

~~Our primary sources of compensation~~revenues for our ~~retail~~ brokerage services ~~are~~is commissions ~~paid by insurance companies, which are usually~~from underwriting enterprises, based ~~upon~~on a percentage of ~~the premium~~premiums paid by ~~insureds,~~our clients, or fees received from clients based on an agreed level of service usually in lieu of commissions. Commissions are fixed at the contract effective date and ~~brokerage and advisory fees paid directly by our clients. For wholesale brokerage services, we~~ generally ~~receive a share of the commission paid to the retail broker from the insurer. Commission rates~~ are ~~dependent~~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 ~~insurance,~~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 ~~company underwriting~~contract. Rather than being tied to the ~~policy and whether we act as a retail or wholesale broker. Advisory~~amount of premiums, fees are ~~dependent~~most often based on ~~the extent and value~~an expected level of ~~services we provide.~~effort to provide our services. In addition, under certain circumstances, both retail brokerage and wholesale brokerage services receive supplemental and contingent ~~commissions. A supplemental commission~~revenues. Supplemental revenue is ~~a commission~~revenue paid by an ~~insurance carrier~~underwriting enterprise that is above the base ~~commissions~~commission paid, is determined by the ~~insurance carrier~~underwriting enterprise and is established annually in advance of the contractual period based on historical performance criteria. ~~A contingent commission~~Contingent revenue is ~~a commission~~revenue paid by an ~~insurance carrier~~underwriting enterprise based on the overall profit and/or volume of the business placed with that ~~insurance carrier~~underwriting enterprise during a particular calendar year and is determined after the contractual period.

Litigation, Regulatory and ~~Regulatory~~Taxation Matters

IRS and DOJ investigations -~~A portion of~~Aspreviously disclosed, our brokerage business includes the development and management of “micro-captives,” through operations we acquired in 2010 in our acquisition of the assets of Tribeca Strategic Advisors (Tribeca). A “captive” is an insurance company that insures the risks of its owner, affiliates or a group of companies. Micro-captives are captive insurance companies that are subject to taxation only on net investment income under IRC ~~Section~~ 831(b)~~. Our micro-captive~~ (or “micro-captive”) advisory services ~~are~~business has been under investigation by the ~~Internal Revenue Service (IRS). Additionally, the~~ IRS ~~has initiated audits for the 2012 tax year of over 100 of the micro-captive insurance companies organized and/or managed by us.~~since 2013. Among other matters, the IRS is investigating whether we have been acting as a tax shelter promoter in connection with these operations. ~~While~~Additionally, the IRS has ~~not made specific allegations relating to our operations or~~initiated audits for the~~pre-acquisition~~ ~~activities~~ 2012 tax year, and subsequent tax years, of ~~Tribeca, if~~over 100 of the ~~IRS were to successfully assert that the micro-captives~~micro-captive underwriting enterprises organized and/or managed by ~~us do~~us.

In May 2020, we learned that the DOJ began conducting a criminal investigation related to IRC 831(b) micro-captive underwriting enterprises. We have been advised that we are not ~~meet~~currently a target of the ~~requirements of IRC Section 831(b),~~investigation. In June 2020 our subsidiary Artex Risk Solutions, Inc. (which we ~~could be subject~~refer to ~~monetary claims by~~as Artex) received a grand jury subpoena requesting documents relating to its micro-captive advisory business. We have produced documents in response to the subpoena. We are fully cooperating with both the IRS ~~and/or our micro-captive clients,~~investigation and ~~our future earnings from our micro-captive operations could be materially adversely affected, any of which events could negatively impact~~ the ~~overall captive business and adversely affect our consolidated results of operations and financial condition.~~DOJ investigation. We may also experience lost earnings due to the negative effect of an extended IRS investigation on our clients’ and potential clients’ businesses. Annual renewals for micro-captive clients generally occur during the fourth quarter. Therefore, any negative impact from this investigation would likely have a disproportionate impact on fourth-quarter results. In the period from 2014 to 2016, our micro-captive operations contributed less than $3.5 million of net earnings and less than $5.0 million in EBITDAC to our consolidated results in any one year. Due to the fact that the IRS has not made any allegation against us or completed its audits of our clients, we are not able to reasonably estimate the amount of any potential loss in connection with these investigations.

Class action lawsuit - On December 7, 2018, a class action lawsuit was filed against us, Artex and other defendants, in the United States District Court for the District of Arizona. The named plaintiffs are micro-captives and their related entities and owners who had IRC Section 831(b) tax benefits disallowed by the IRS. The complaint alleges that the defendants defrauded the plaintiffs by marketing and managing micro-captives with the knowledge that the captives did not constitute bona fide insurance and thus would not qualify for tax benefits. The complaint does not specify the amount of damages sought by the named plaintiffs. On August 5, 2019, the trial court granted the defendants’ motion to compel arbitration and dismissed the class action lawsuit. Plaintiffs appealed this ~~investigation.~~ruling to the United States Court of Appeals for the Ninth Circuit. On September 9, 2020, the Ninth Circuit affirmed the ruling of

~~- 39 -~~the trial court dismissing the class action lawsuit. On March 17, 2021, plaintiffs filed a petition for writ of certiorari with the United States Supreme Court. We will continue to defend against the lawsuit vigorously. Litigation is inherently uncertain, however, and it is not possible for us to predict the ultimate outcome of this matter and the financial impact to us, nor are we able to reasonably estimate the amount of any potential loss in connection with this lawsuit.

Financial information relating to our brokerage segment results for the three-month ~~and nine-month periods~~period ended ~~September 30, 2017~~March 31, 2021 as compared to the same ~~periods~~period in ~~2016,~~2020, is as follows (in millions, except per share, percentages and workforce data):

Acquisition integration costs include costs related to our July 2, 2014 acquisition of Noraxis Capital Corporation (which we refer to as Noraxis), our June 16, 2014 acquisition of the Crombie/OAMPS operations (which we refer to as Crombie/OAMPS), our April 1, 2014 acquisition of Oval Group of Companies (which we refer to as Oval), our November 14, 2013 acquisition of the Giles Group of Companies (which we refer to as Giles) and our August 1, 2015 acquisition of William Gallagher Associates Insurance Brokers (which we refer to as WGA) that are not expected to occur on an ongoing basis in the future once we fully assimilate these acquisitions. These costs relate to the~~on-boarding~~ of employees, communication system conversion costs, related performance compensation, redundant workforce, extra lease space, duplicate services and external costs incurred to assimilate the acquired businesses with our IT related systems. The WGA integration costs in the three-month and nine-month periods ended September 30, 2017 totaled $0.4 million and $1.1 million, respectively, and were primarily related to retention and incentive compensation. The Crombie/OAMPS integration costs in the three-month and nine-month periods ended September 30, 2017 totaled $0.3 million and $1.1 million, respectively, and were primarily related to technology costs and incentive compensation. The Giles and Oval integration costs in the~~three-month~~ and nine-month periods ended September 30, 2017 totaled $2.8 million and $7.5 million, respectively, and were primarily related to the consolidation of offices in the U.K., technology costs, branding and incentive compensation. The WGA integration costs in the three-month and nine-month periods ended September 30, 2016 totaled $2.0 million and $4.4 million, respectively, and were primarily related to retention and incentive compensation. The Noraxis integration costs in the three-month and nine-month periods ended September 30, 2016 totaled $0.7 million and $1.5 million, respectively, and were primarily related to the consolidation of offices, technology costs and incentive compensation. The Crombie/OAMPS integration costs in the three-month and nine-month periods ended September 30, 2016 totaled $0.9 million and $4.0 million, respectively, and were primarily related to technology costs and incentive compensation. The Giles and Oval integration costs in the~~three-month~~ and nine-month periods ended September 30, 2016 totaled $5.8 million and $25.6 million, and were primarily related to the consolidation of offices in the U.K., technology costs, branding and incentive compensation. The prior period integration costs relate to the WGA, Noraxis, Crombie/OAMPS, Oval and Giles acquisitions. Integration costs related to these acquisitions for the full year 2017 are estimated to be less than a third of what they were in 2016.

Commissions and fees-The aggregate increase in base commissions and fees for the three-month period ended ~~September 30, 2017~~March 31, 2021, compared to the same period in ~~2016,~~2020, was ~~principally~~ due to ~~combination of~~ revenues associated with acquisitions that were made in the twelve-month period ended ~~September 30, 2017~~March 31, 2021 ($~~37.1~~50.2 million), and to the organic ~~growth. Commissions~~change in base commissions and fees in the three-month period ended September 30, 2017 included new business production of $99.0 million, which was offset by lost business and renewal rate decreases of $62.7 million. Organic growthfee revenues. The organic change in base commissions and fee revenues was ~~3.7%~~4.9% and ~~2.4%~~3.8% for the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively.

~~The aggregate increase in base commissions and fees for~~In our property/casualty brokerage operations, during the ~~nine-month~~three-month period ended ~~September 30, 2017~~March 31, 2021, (a) our customer retention and new business generation remained similar to pre-pandemic levels, (b) renewal exposure units (i.e., insured values, payrolls, employees, miles driven, etc.) were lower than pre-pandemic first quarter 2020, but higher than the last three quarters of 2020, (c) premium rates across most geographies and lines of coverage have continued to increase, effectively mitigating exposure unit declines, and (d) mid-term policy modifications (including cancellations) were a net positive, similar to first quarter 2020. Thus far in second quarter 2021, property/casualty new business, retentions and mid-term policy modifications are trending similar to first quarter 2021 and are much improved compared to lows seen in April and May 2020, as our customers’ businesses continue to recover and economic activity increases. We continue to see overall property/casualty premium rates move higher and exposure units also trended higher than first quarter 2021. In our employee benefits brokerage operations, during the ~~same period in 2016, was principally due to combination of revenues associated with acquisitions that were made in the twelve-month~~three-month period ended ~~September 30, 2017 ($124.4 million)~~March 31, 2021, (a) we saw a slight improvement in covered lives on renewal business compared to fourth quarter 2020, yet still lower than pre-pandemic levels, and ~~to organic growth. Commissions~~(b) new consulting and ~~fees in thenine-month~~ ~~period ended September 30, 2017 included new business production of $273.5 million, which~~special project work was offset by lost business and renewal rate decreases of $220.2 million.

~~The decrease~~Depreciation- Depreciation expense increased in ~~operating expense for~~ the ~~nine-month~~three-month period ended ~~September 30, 2017~~March 31, 2021 compared to the same period in ~~2016 was primarily due to decreases~~2020 by $4.5 million.

Amortization- ~~45 -~~

~~Amortization~~- The ~~increase~~decrease in amortization expense in thethree-month ~~and nine-month periods~~ period ended ~~September 30, 2017~~March 31, 2021 compared to the same ~~periods~~period in ~~2016 were~~ 2020 was primarily due to write-off of amortizable intangible assets and amortization expense of intangible assets associated with acquisitions completed in the ~~twelve-month~~three-month period ended ~~September 30, 2017.~~ March 31, 2021. Based on the results of impairment reviews during the three-month period ended March 31, 2021, we wrote off $5.1 million of amortizable assets. Based on the results of impairment during the three-month period ended March 31, 2020, we wrote off $45.8 million of amortizable assets. 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. In reviewing 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. In consideration of the potentialimpacts of COVID-19 on our reporting units, we performed a qualitative impairmentreview oncarrying value of our goodwill for all of our reporting units as of March 31, 2021 and no indicators of impairment were noted.

Expiration lists,non-compete agreements and trade names are amortized using the straight-line method over their estimated useful lives ~~(three~~(two to fifteen years for expiration lists, ~~three~~two to ~~five~~six years fornon-compete agreements and ~~five~~two to ~~ten~~fifteen years for trade names). Based on the results of impairment reviews during the three-month and nine-month periods ended September 30, 2017, we wrote off $4.5 million and $6.2 million, respectively, of amortizable intangible assets related to the brokerage segment. Based on the results of impairment reviews during the three-month and nine-month periods ended September 30, 2016, we wrote off $1.5 million and $1.8 million, respectively, of amortizable intangible assets related to the brokerage segment.

Change in estimated acquisition earnout payables-The change in the expense from the change in estimated acquisition earnout payables in the~~three-month~~ ~~and nine-month periods~~ three‑month period ended ~~September 30, 2017~~March 31, 2021, compared to the same ~~periods~~period in ~~2016,~~ 2020, was primarily due to adjustments made to the estimated fair value of earnout obligations related to revised projections of future performance. During the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we recognized ~~$4.8~~$8.8 million and ~~$4.3~~$10.5 million, respectively, of expense related to the accretion of the discount recorded for earnout obligations in connection with our acquisitions made in the period from ~~2014~~2017 to 2017. During the nine-month periods ended September 30, 2017 and 2016, we recognized $14.9 million and $12.5 million, respectively, of expense related to the accretion of the discount recorded for earnout obligations in connection with our acquisitions made in the period from 2014 to 2017.2021. In addition, during thethree-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we recognized ~~$6.3~~$3.6 million of expense and ~~$0.2~~$95.2 million of income, respectively, related to net adjustments in the estimated fair value of earnout obligations in connection with revised projections of future performance for 3023 and 2771 acquisitions, respectively. ~~In addition, during thenine-month~~ periods ended September 30, 2017 and 2016, we recognized $12.9 million and $8.7 million of expense, respectively, related to net adjustments in the estimated fair value of earnout obligations in connection with revised projections of future performance for 88 and 77 acquisitions, respectively.

The amounts initially recorded as earnout payables for our ~~2014~~2017 to ~~2017~~2021 acquisitions were measured at fair value as of the acquisition date and are primarily based upon the estimated future operating results of the acquired entities over atwo- to three-year period subsequent to the acquisition date. The fair value of these earnout obligations is based on the present value of the expected future

- 47 -

payments to be made to the sellers of the acquired entities in accordance with the provisions outlined in the respective purchase agreements. In determining fair value, we estimate 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. We ~~estimated~~estimate future earnout payments using the earnout formula and performance targets specified in each purchase agreement and these financial projections. Subsequent changes in the underlying financial projections or assumptions will cause the estimated earnout obligations to change and such adjustments are recorded in our consolidated statement of earnings when incurred. Increases in the earnout payable obligations will result in the recognition of expense and decreases in the earnout payable obligations will result in the recognition of income.

Provision for income taxes- The brokerage segment’s effective income tax rates for the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016~~2020, were ~~33.4% (33.4% on a controlling interests basis)~~24.1% and 34.5% (34.4% on a controlling interests basis), respectively. The brokerage segment’s effective income tax rates for the nine-month periods ended September 30, 2017 and 2016 were 33.9% (34.4% on a controlling interests basis) and 34.8% (35.2% on a controlling interests basis)24.2%, respectively. We anticipate reporting an effective tax rate of approximately ~~34.0%~~23.0% to ~~36.0% (on a controlling interests basis)~~25.0% in our brokerage segment for the foreseeable future.

Net earnings ~~(loss)~~ attributable to noncontrolling interests-The amounts reported in this line for the three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016~~2020, include noncontrolling interest ~~(loss)~~ earnings of ~~($0.3)~~$1.8 million and ~~($0.2)~~$0.7 million, respectively, and $7.1 million and $4.1 million, respectively, for the nine-month periods ended September 30, 2017 and 2016, primarily related to our investment in Capsicum Reinsurance Brokers LLP (which we refer to as Capsicum). We are partners in this venture with Grahame Chilton, the CEO of our International Brokerage Division. We are the controlling partner, participating in 33% of Capsicum’s net operating results and Mr. Chilton owns approximately 50% of Capsicum.respectively.

Fees - The increase in fees for the three-month period ended ~~September 30, 2017~~March 31, 2021 compared to the same period in ~~2016~~2020 was due primarily to the impact of COVID-19 in 2020. In our risk management operations, we began seeing a meaningful decline in new ~~business~~claims arising during March 2020. First quarter 2021 new claims arising were consistent with fourth quarter 2020, but still below pre-pandemic first quarter 2020 levels. A slower recovery or reversal in the number of ~~$22.3 million and claim audit timing of approximately $4.0 million, which were partially offset by lost business of $6.3 million and lower international performance bonus fees.~~workers employed could cause fewer claims to arise in future quarters. Organic change in fee revenues for the three-month period ended ~~September 30, 2017~~March 31, 2021 was ~~10.2%~~0.6% compared to ~~0.7%~~4.2% for the same period in ~~2016.~~

The increase in fees for the nine-month period ended September 30, 2017 compared to the same period in 2016 was due primarily to new business of $54.5 million and higher international performance bonus fees, which were partially offset by lost business of $22.9 million. Organic change in fee revenues for the nine-month period ended September 30, 2017 was 5.8% compared to 0.7% for the same period in 2016.2020.

The $3.2 million increase in compensation expense for the three-month period ended ~~September 30, 2017~~March 31, 2021 compared to the same period in ~~2016~~2020, was primarily due ~~to increased headcount, an unfavorable foreign currency translation ($0.5 million) and increases in salaries and~~other incentive compensation ~~($7.5~~linked to operating results and deferred compensation - $3.4 million in the aggregate), temporary-staffing expense ($0.8 million), deferred compensation ($0.3 million) and stock compensation expense ($0.2 million), offset by decreases in employee benefits expense ($0.5 million) and severance related costs ($0.2 million).

The increase in compensation expense for the nine-month period ended September 30, 2017 compared to the same period in 2016 was primarily due to increased headcount, an unfavorable foreign currency translation ($0.3 million) and increases in salaries and incentive compensation ($14.2 million in the aggregate), deferred compensation ($1.2 million), temporary-staffing expense ($1.2 million), employee benefits expense ($0.6 million) and stock compensation expense ($0.4 million),aggregate, partially offset by a decrease in severance related costs ($0.6 million).

The $0.5 million increase in operating expense for the three-month period ended ~~September 30, 2017~~March 31, 2021 compared to the same period in ~~2016~~2020, was primarily due to increases in technology expense - $1.4 million and business insurance - $1.3 million, partially offset by decreases primarily in professional and banking fees ~~($2.9 million), business insurance ($1.8 million), other~~and meeting and client entertainment expense ~~($1.7 million), outside consulting fees ($0.6 million), employee~~- $2.2 million in the aggregate.

Depreciation- Depreciation expense ~~($0.5 million), technology expenses ($0.5 million), licenses and fees ($0.2 million), office supplies ($0.1 million) and outside services ($0.1 million), offset by a decrease~~decreased in ~~real estate expenses ($0.3 million).~~

~~The increase in operating expense for~~ the ~~nine-month~~three-month period ended ~~September 30, 2017~~March 31, 2021 compared to the same period in 2016 was primarily due to increases in professional and banking fees ($6.1 million), outside consulting fees ($2.8 million), other expense ($2.5 million), employee expense ($1.3 million), business insurance ($0.7 million), office supplies ($0.3 million), licenses and fees ($0.3 million), outside services ($0.3 million) and meeting and client entertainment expense ($0.1 million), offset2020 by ~~decreases in real estate expenses ($0.9 million), technology expenses ($0.5 million) and bad debt expense ($0.3 million).~~

~~Depreciation~~-~~Depreciation expense increased slightly in thethree-month~~ ~~and nine-month periods ended September 30, 2017 compared to the same periods in 2016 and~~$0.8 million. This decrease reflects the impact ~~of purchases~~ of furniture, equipment and leasehold improvements becoming fully depreciated in 2020 and leasehold improvements being written off in 2020 related to ~~office expansions~~the termination of real estate leases and ~~relocations, and expenditures related to upgrading computer systems.~~abandonment of leased spaces.

Benefit for income taxes- We allocate the provision for income taxes to the brokerage and risk management segments using local statutory rates. As a result, the provision for income taxes for the corporate segment reflects the entire benefit to us of the ~~IRS~~IRC Section 45 tax credits generated, because that is the segment which produced the credits. The law that provides for IRC Section 45 tax credits ~~substantially expires~~expired in December 2019 for our fourteen 2009 Era Plants and is scheduled to expire in December 2021 for our ~~twenty~~twenty-one 2011 Era Plants. Our consolidated effective tax rate for the three-month period ended ~~September 30, 2017~~March 31, 2021 was ~~(42.5)%~~3.6% compared to ~~(37.4)%~~0.2% for the same period in ~~2016. Our consolidated effective tax rate for the nine-month period ended September 30, 2017 was (30.4)% compared to (19.4)% for the same period in 2016.~~2020. The tax rates for ~~September 30, 2017~~the three-month periods ended March 31, 2021 and ~~2016~~2020 were lower than the statutory rate primarily due to the amount of IRC Section 45 tax credits recognized during the ~~period.~~periods. There were ~~$157.1~~$55.2 million and ~~$144.7~~$70.4 million of Section 45 tax credits recognized in the~~nine-month~~ three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. There were ~~$174.3~~$52.6 million and ~~$145.2~~$31.2 million of tax credits produced in the~~nine-month~~ three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. ~~Also, impacting~~In 2020, our U.K. effective income tax rate increased from 17.5% to 19.0% and we incurred one-time taxes associated with realignment of our operations to continue to conduct certain business in the ~~benefit~~European Union after Brexit.

Net earnings attributable to noncontrolling interests - The amounts reported in this line for the ~~income taxes line~~three-month periods ended March 31, 2021 and 2020 include non-controlling interest earnings of $10.1 million and $7.3 million, respectively, related to our investment in Chem-Mod LLC. As of March 31, 2021 and 2020, we held a 46.5% controlling interest in Chem-Mod LLC. Also included in net earnings attributable to noncontrolling interests are offsetting amounts related to non-Gallagher owned interests in several clean energy investments.

The following provides non-GAAP information that we believe is helpful when comparing our operating results for the ~~adoption~~three-month periods ended March 31, 2021 and 2020 for the corporate segment (in millions):

(2)	Corporate pre-tax loss includes a net unrealized foreign exchange remeasurement loss of $4.1 million in first quarter 2021 and a net unrealized foreign exchange remeasurement gain of $12.4 million in first quarter 2020.

Interest and banking costs - Interest and banking costs includes expenses related to our debt.

Clean energy related - Includes the operating results related to our investments in clean coal production plants and Chem-Mod LLC.

Acquisition costs - Consists of aexternal professional fees, due diligence and other costs incurred related to our acquisitions.

Corporate - Consists of overhead allocations mostly related to corporate staff compensation and other corporate level activities, cross-selling and motivational meetings for our production staff and field management, expenses related to our new ~~accounting pronouncement, whereby it requires that~~corporate headquarters and the ~~income tax effects~~impact of ~~awards be recognized in the income statement when the awards vest or are settled, rather than recognizing the tax benefits in excess of compensation costs through stockholders’ equity.~~ foreign currency translation. The income tax benefit of stock based awards that vested or were settled in the ~~nine-months ended September 30, 2017 was $11.9 million.~~

~~Potential U.S. Federal income tax law changes~~- The value of our tax credits could be impacted by changes in the tax code as a result of the recent presidential and congressional elections in the U.S. Congress could modify or repeal IRC Section 45 and remove the tax credits (either prospectively or through the elimination of the carryover of the credits),

~~- 53 -~~

which would adversely affect the value of our investment. Also, if Congress reduces tax rates, although we might pay less in taxes overall, it would reduce the tax benefit of operating costs associated with the production of refined coal. Although we are unable to predict how a reduction in tax rates during 2017 would affect our cash taxes paid in 2017, we estimate that if the U.S. Federal corporate income tax rate had been reduced from 35% to 20% and if the Alternative Minimum Tax had been eliminated as of January 1, 2016, our cash taxes paid for fiscal 2016 would have been $39.1 million rather than $66.1 million.

~~Net earnings attributable to noncontrolling interests~~ ~~- The amounts reported in this line for the~~ three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016 includenon-controlling~~ interest earnings of $9.2 million and $9.1 million respectively related to our investment in Chem-Mod LLC.

Pretax earnings (loss) for the third quarter are presented net of amounts attributable to noncontrolling interests of $7.7 million in 2017 and $7.8 million in 2016. Pretax earnings (loss) for the nine-month periods are presented net of amounts attributable to noncontrolling interests of $20.9 million in 2017 and $20.6 million in 2016.

Interest and banking costs includes expenses related to our debt. Clean energy related includes the operating results related to our investments in clean coal production plants and Chem-Mod. Acquisition costs include professional fees, due diligence and other costs incurred related to our acquisitions. Corporate consists of overhead allocations mostly related to corporate staff compensation and other corporate level activities, costs related to a biennial company-wide award, cross-selling and motivational meeting for our production staff and field management, expenses related to our new corporate headquarters, corporate related marketing costs and expenses for systems and consulting related to the implementation of the new revenue recognition accounting rules.

~~Corporate -~~~~During the nine-month period ended September 30, 2017, we incurred $8.4 million ofpre-tax~~ costs related to implementing a new accounting standard related to how companies recognize revenue, which will be effective beginning in January 2018. We expect to incur costs related to implementing this new accounting standard in each of the next two quarters. These charges will be presented in the corporate segment. A new accounting pronouncement, ASU~~No. 2016-09,~~ ~~Improvements to Employee Share-Based Payment Accounting,~~2020 was effective January 1, 2017. It requires that the income tax effects of awards be recognized in the income statement (in the Income Tax Benefit column above) when the awards vest or are settled, rather than recognizing the tax benefits in excess of compensation costs through stockholders’ equity. The income tax benefit of stock based awards that vested or were settled in the nine-month period ended September 30, 2017 was $11.9$9.0 million and is included in the table above in the Corporate line. The income tax benefit of stock based awards that vested or were settled in the nine-month period ended September 30, 2016 were $4.8 million and are not included in the Income Tax Benefit column above.

~~Litigation Settlement -~~ During the third quarter of 2015, we settled litigation against certain former U.K. executives and their advisors for a pretax gain of $31.0 million ($22.3 million net of costs and taxes). Incremental expenses that arose in connection with this matter resulted in quarterly~~after-tax~~ ~~charges being incurred through September 30, 2017 were $8.8 million.~~

~~Home Office Lease Termination/Move -~~ ~~During first quarter 2017, we relocated our corporate office headquarters to a nearby suburb of Chicago. Move-relatedafter-tax~~ ~~charges were $7.9 million in the first nine months of 2017.After-tax~~ ~~move related charges are expected to total approximately $0.5 million in the fourth quarter of 2017.~~

The estimated earnings information in the table reflects management’s current best estimate of the ~~2017~~2021 low and high ranges of~~after-tax~~ after‑tax earnings based on early production estimates from the host utilities, other operating assumptions, ~~and~~including current U.S. ~~Federal~~federal income tax ~~laws in place at September 30, 2017.~~laws. However, coal-fired power plants may not ultimately produce refined fuel at estimated levels due to seasonal electricity demand, production costs, natural gas prices, weather conditions, as well as many other operational, regulatory and environmental compliance reasons. Future changes in EPA regulations or U.S. ~~Federal~~federal income tax laws might materially impact these estimates. Please refer to our filings with the SEC, including Item 1A, “Risk Factors,” on pages ~~18, 19~~20, 21 and 2022 of our Annual Report on Form~~10-K~~ 10‑K for the fiscal year ended December 31, ~~2016,~~2020, for a more detailed discussion of these and other factors that could impact the information above.

~~- 55 -~~

Our investment in Chem-Mod LLC generates royalty income from refined coal production plants owned by those limited liability companies in which we invest as well as refined coal production plants owned by other unrelated parties. Future changes in EPA regulations or U.S. ~~Federal~~federal income tax laws might materially impact ~~these~~the earnings estimates.

~~In our most recent Annual Report onForm 10-K,~~ ~~we disclosed that on February 10, 2017 one of the refined coal partnerships in which we are an investor received a notice from the IRS setting forth its view that certain of ourco-investors~~ ~~are unable to claim tax credits based on the structure of the partnership. On June 15, 2017, the IRS issued a final notice to the same refined coal partnership disallowing ourco-investors~~ ~~from claiming tax credits. The position taken by the IRS has the potential to affect, and the IRS has opened audits of, other partnerships in which theseco-investors~~ are invested. However, the IRS notices do not challenge the validity of the tax credits themselves, or our ability to utilize tax credits. The partnership affected by the June 15, 2017 notice will defend its position in tax court. However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of this proceeding.

Financial Condition and Liquidity

Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations. The insurance brokerage industry is not capital intensive. Historically, our capital requirements have primarily included dividend payments on our common stock, repurchases of our common stock, funding of our investments, acquisitions of brokerage and risk management operations and capital expenditures.

In light of the economic uncertainty caused by COVID-19, subsequent to the first quarter of 2020, we preserved liquidity during 2020 by reducing capital expenditures for the remainder of 2020 and made working capital process changes such as moving more cash into the U.S. from our international operations, pursued collections on receivables from our customers and partners and renegotiated longer payment terms on vendor payables. We also slowed down our acquisition program in the second and third quarters of 2020. Some of these initiatives and trends continued into first quarter 2021 and will continue in the foreseeable future. We believe we have sufficient liquidity on hand to continue business operations during this uncertain period. If we experience a significant reduction in revenue in the future, we have additional alternatives to maintain liquidity, including use of common stock to fund future acquisitions.

Cash Flows From Operating Activities

Historically, we have depended on our ability to generate positive cash ~~flows~~flow from operations to meet a substantial portion of our cash requirements. We believe that our cash flows from operations and borrowings under our Credit Agreement (defined below) will provide us with adequate resources to meet our liquidity needs in the foreseeable future. To fund acquisitions made during ~~2016~~2020 and for the ~~nine-month~~three-month period ended ~~September 30, 2017,~~March 31, 2021, we relied on a combination of net cash flows from operations, ~~and~~ proceeds from borrowings under our Credit Agreement, proceeds from issuances of senior unsecured notes and ~~note purchase agreements.~~issuances of our common stock.

Cash provided by operating activities was ~~$459.1 million~~$286.3 and ~~$368.9~~$108.6 million for the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. The increase in cash provided by operating activities during the~~nine-month~~ three‑month period ended ~~September 30, 2017~~March 31, 2021 compared to the same period in ~~2016~~2020 was ~~partially~~primarily due to timing differences between periods in the payment of accrued compensation and other accrued liabilities compared to the same period in 2020. During the three-month period ended March 31, 2020, we paid annual bonus payments relating to 2019. Annual bonus amounts relating to 2020 were paid in second quarter 2021. During 2020 and for the three‑month period ended March 31, 2021, we managed our working capital in terms of receivables and payables as a cautionary step to protect liquidity during this uncertain period. During the three-month period ended March 31, 2021, employee matching contributions to the 401(k) plan of $63.6 million relating to 2020 were funded using common stock. During the three-month period ended March 31, 2020, employee matching contributions to the 401(k) plan of $59.4 million relating to 2019 were funded using cash.

- 55 -

Cash provided by operating activities for the three-month period ended March 31, 2021 was unfavorably impacted by timing differences in the receipts and disbursements of client fiduciary related balances in ~~2017~~2021 compared to ~~2016. In addition, we had an unrealized foreign currency measurement gain in 2017 compared to an unrealized foreign currency measurement loss for the same period in 2016.~~2020. The following table summarizes ~~four~~two lines from our consolidated statement of cash flows and provides information that management believes is helpful when comparing changes in client fiduciary related balances ~~and unrealized foreign currency remeasurement activity in our consolidated statement of cash flows~~ for the~~nine-month~~ three-month period ended ~~September 30, 2017~~March 31, 2021 with the same period in ~~2016~~2020 (in millions):

In addition, cash provided by operating activities for the nine-month period ended September 30, 2017 was favorably impacted by timing differences in the payment of accrued liabilities compared to the same period in 2016.

Our cash flows from operating activities are primarily derived from our earnings from operations, as adjusted for ~~realized gains and losses, and~~ our~~non-cash~~ non‑cash expenses, which include depreciation, amortization, change in estimated acquisition earnout payables, deferred compensation, restricted stock and~~stock-based~~ stock‑based and othernon-cash compensation expenses. Cash provided by operating activities can be unfavorably impacted byif the amount of IRC Section 45 tax credits ~~recognized compared to~~generated (which is the amount we recognize for financial reporting purposes) is greater than the amount of tax credits ~~actually used during the respective periods.~~utilized to reduce our tax cash obligations. Excess tax credits produced during the period result in an increase to our deferred tax assets, which is a net use of cash related to operating activities. Please see “Clean ~~energy investments”~~Energy Investments” below for more information on their potential future impact on cash provided by operating activities.

~~- 56 -~~

When assessing our overall liquidity, we believe that the focus should be on net earnings as reported in our consolidated statement of earnings, adjusted for~~non-cash~~ non‑cash items (i.e., EBITDAC), and cash provided by operating activities in our consolidated statement of cash flows. Consolidated EBITDAC was ~~$705.6~~$614.8 million and ~~$652.3~~$489.9 million for the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. Net earnings attributable to controlling ~~interest~~interests were ~~$358.0~~$382.1 million and ~~$319.3~~$346.3 million for the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. We believe that EBITDAC items are indicators of trends in liquidity. From a balance sheet perspective, we believe the focus should not be on premiums and fees receivable, premiums payable or restricted cash for trends in liquidity. Net cash flows provided by operations will vary substantially from quarter to quarter and year to year because of the variability in the timing of premiums and fees receivable and premiums payable. We believe that in order to consider these items in assessing our trends in liquidity, they should be looked at in a combined manner, because changes in these balances are interrelated and are based on the timing of premium payments, both to and from us. In addition, funds legally restricted as to our use relating to premiums and clients’ claim funds held by us in a fiduciary capacity are presented in our consolidated balance sheet as “Restricted ~~Cash”~~cash” and have not been included in determining our overall liquidity.

Our policy for funding our defined benefit pension plan is to contribute amounts at least sufficient to meet the minimum funding requirements under the IRC. The Employee Retirement Security Act of 1974, as amended (which we refer to as ERISA), could impose a minimum funding requirement for our plan. We are not required to make any minimum contributions to the plan for the ~~2017~~2021 plan year, nor were we required to make any minimum contributions to the plan for the ~~2016~~2020 plan year. Funding requirements are based on the plan being frozen and the aggregate amount of our historical funding. The plan’s actuaries determine contribution rates based on our funding practices and requirements. Funding amounts may be influenced by future asset performance, the level of discount rates and other variables impacting the assets and/or liabilities of the plan. In addition, amounts funded in the future, to the extent not due under regulatory requirements, may be affected by alternative uses of our cash flows, including dividends, acquisitions and common stock repurchases. We did not make any discretionary contributions to the plan during the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016.~~2020. We are not considering making ~~additional~~any discretionary contributions to the plan in ~~2017,~~2021, but may be required to make significantly larger minimum contributions to the plan in future periods.

Cash Flows From Investing Activities

Capital Expenditures -~~Net capital~~Capital expenditures were ~~$93.8~~$27.2 million and ~~$138.8~~$29.5 million for the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. In ~~2017,~~2021, we expect total expenditures for capital improvements to be approximately ~~$135.0~~$140.0 million, part of which is related to expenditures on ~~our new corporate headquarters building (approximately $30.0 million),~~ office moves ~~and expansions~~ and updating computer systems and equipment. ~~Relating to the development of our new corporate headquarters, we expect to receive property tax related credits under atax-increment~~ financing note from Rolling Meadows, Illinois and an Illinois state Edge tax credit. Incentives from these two programs could total between $60.0 million and $80.0 million over a fifteen-year period starting in late 2016 for the Edge tax credit and 2017 for the~~tax-increment~~ ~~financing note.~~

Acquisitions - Cash paid for acquisitions, net of cash and restricted cash acquired, ~~were $320.5~~was $395.6 million and ~~$147.0~~$76.2 million in the~~nine-month~~ three‑month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. In addition, during the ~~nine-month~~three-month period ended ~~September 30, 2017,~~March 31, 2021, we issued ~~0.7~~0.6 million shares ($~~43.2~~66.9 million) of our common stock as payment for a portion of the total consideration paid for ~~2017~~2021 acquisitions and earnout payments made in ~~2017.~~2021. During the~~nine-month~~ three-month period ended ~~September 30, 2016,~~March 31, 2020, we issued ~~1.9~~0.7 million shares ($~~85.7~~72.4 million) of our common stock as payment for consideration paid for ~~2016~~2020 acquisitions and earnout payments made in ~~2016.~~2020. We completed ~~thirty~~six acquisitions and ~~twenty-eight~~eight acquisitions in the~~nine-month~~ three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, respectively. Annualized revenues of businesses acquired in the~~nine-month~~ three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016~~2020 totaled approximately ~~$143.0~~$103.7 million and ~~$97.8~~$124.2 million, respectively. WeDuring 2020, the company made the decision to fund the majority of the consideration paid for acquisitions and earnout payments made using company stock to preserve cash. For the remainder of 2021, we expect to use cash from operations, our Credit Agreement, new debt and ~~debt~~our common stock, or a combination thereof to fund all ~~or a portion~~ of the acquisitions we ~~complete through the remainder of 2017.~~complete.

If liquidity concerns arise, we may be more likely to issue common stock to fund acquisitions.

Dispositions-During the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we sold several books of business and recognized~~one-time~~ net gains of ~~$3.1~~$4.1 million and ~~$4.7~~$0.2 million, respectively. We received net cash proceeds of ~~$2.9~~$5.3 million and ~~$7.3~~$1.1 million related to the ~~2017~~2021 and ~~2016~~2020 transactions, respectively.

Clean Energy Investments-During the period from 2009 through ~~2017,~~2020, we have made significant investments in clean energy operations capable of producing refined coal that we believe qualifies for tax credits under IRC Section 45. Our current estimate of the ~~2017~~2021 annual adjusted net after-tax earnings, including IRC Section 45 tax credits, which will be

~~- 57 -~~

produced from all of our clean energy investments in ~~2017,~~2021, is ~~$123.0~~$70.0 million to ~~$129.0~~$80.0 million. The IRC Section 45 tax credits generate positive cash flow by reducing the amount of ~~Federal~~federal income taxes we pay, which is offset by the operating expenses of the plants, by capital expenditures related to the redeployment, and in some cases the relocation of refined coal plants. We anticipate positive net cash flow related to IRC Section 45 activity in ~~2017.~~2021. However, there are several variables that can impact net cash flow from clean energy investments in any given year. Therefore, accurately predicting positive or negative cash flow in particular future periods is not possible at this time. Nonetheless, if current ownership interests remain the same, if capital expenditures related to redeployment and relocation of refined coal plants ~~remains~~remain as currently anticipated, and if we continue to generate sufficient taxable income to use the tax credits produced by our IRC Section 45 investments, we anticipate that these investments will continue to generate positive net cash flows ~~for the period 2017~~ through at least ~~2021.~~2025. While we cannot precisely forecast the cash flow impact in any particular period, we anticipate that the net cash flow impact of these investments will be positive overall. Please see “Clean energy investments” on pages 5554 and 5655 for a more detailed description of ~~the~~these investments and their risks and uncertainties. Please see “Other Information” on page 37 for the cash flow impact of the expiration of laws governing tax credits.

Cash Flows From Financing Activities

On ~~April 8, 2016,~~June 7, 2019, we entered into an amendment and restatement to our multicurrency credit agreement dated ~~September 19, 2013~~April 8, 2016 (which we refer to as the Credit Agreement) ~~with a group of fifteen financial institutions. The~~. On August 27, 2020, we entered into an amendment ~~and restatement, among other things, extended the expiration date of~~to the Credit Agreement from September 19, 2018 to April 8, 2021 and increased the revolving credit commitment from $600.0 million to $800.0 million, of which $75.0 million may be used for issuances of standby or commercial letters of credit and up to $75.0 million may be used for the making of swing loans (as defined in the Credit Agreement)Agreements. We may from time to time request, subject to certain conditions, an increase in the revolving credit commitment under the Credit Agreement up to a maximum aggregate revolving credit commitment of $1,100.0 million. At September 30, 2017, $75.0 million of

There were no borrowings ~~were~~ outstanding ~~under the Credit Agreement. Due to borrowings and $20.7 million of outstanding letters of credit, $704.3 million remained available~~ under the Credit Agreement at ~~September 30, 2017.~~March 31, 2021. Due to the outstanding letters of credit, $1,185.8 million remained available for potential borrowings under the Credit Agreement at March 31, 2021.

We use the Credit Agreement to post letters of credit and to borrow funds to supplement our operating cash flows from time to time. In the ~~nine-month~~three-month period ended ~~September 30, 2017,~~March 31, 2021, we borrowed ~~$3,223.0~~$430.0 million and repaid ~~$3,426.0~~$430.0 million under our Credit Agreement. In the ~~nine-month~~three-month period ended ~~September 30, 2016~~March 31, 2020, we borrowed ~~$1,619.5~~$1,730.0 million and repaid ~~$1,556.5~~$1,970.0 million under ~~the~~our Credit Agreement. Principal uses of the ~~2017~~2021 and ~~2016~~2020 borrowings under the Credit Agreement were to fund acquisitions, ~~make~~ earnout payments related to acquisitions and ~~for~~ general corporate purposes.

~~We have a secured~~On September 16, 2020, 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 amendment, among other things, extended the expiration date of the Premium Financing Debt Facility from July 18, 2021 to September 15, 2022, added six-months variable limits to Facility B NZ$ beginning in 2021 and increased the total commitment for the AU$ denominated tranche from AU$245.0 million to AU$310.0 million. The Premium Financing Debt Facility is comprised of: (i) Facility B, ~~which~~ is separated into AU$~~160.0~~260.0 million and NZ$25.0 million tranches, (ii) Facility C, an AU$~~25.0~~50.0 million equivalent multi-currency overdraft tranche and (iii) Facility D, a NZ$15.0 million equivalent multi-currency overdraft tranche. ~~The Premium Financing Debt Facility expires May 18, 2019.~~ At ~~September 30, 2017, $156.4~~March 31, 2021, AU$175.0 million and NZ$0.0 million of borrowings were outstanding under Facility B, AU$10.0 million of borrowings outstanding under Facility C and NZ$14.0 million of borrowings were outstanding under Facility D, which in aggregate amount to US$151.3 million of borrowings outstanding under the Premium Financing Debt Facility.

On January 30, 2020, we closed and funded an offering of $575.0 million aggregate principal amount of fixed rate private placement unsecured senior notes. The weighted average maturity of these notes is 11.7 years and the weighted average interest rate is 4.23% per

- 57 -

annum after giving effect to underwriting costs and the net hedge loss. In 2017 and 2018, we entered into pre-issuance interest rate hedging transactions related to these private placements. We realized a net cash loss of approximately $8.9 million on the hedging transactions that will be recognized on a pro rata basis as an increase to our reported interest expense over a ten year period.

The notes consist of the following tranches:

•

$30.0 million of 3.75% senior notes due in 2027;

•

$341.0 million of 3.99% senior notes due in 2030;

•

$69.0 million of 4.09% senior notes due in 2032;

•

$79.0 million of 4.24% senior notes due in 2035; and

•

$56.0 million of 4.49% senior notes due in 2040

We used these offerings to repay certain existing indebtedness and for general corporate purposes, including to fund acquisitions.

On February 10, 2021, we closed a private placement of $100.0 million aggregate principal amount of unsecured senior notes. The unsecured senior notes were issued with an interest rate of 2.44% and are due in 2036. We used the proceeds of these offerings in part to fund the $75.0 million February 10, 2021 Series D note maturity, and for acquisitions and general corporate purposes. The weighted average interest rate is 3.97% after giving effect to a net hedging loss. In 2018, we entered into a pre-issuance interest rate hedging transaction related to this private placement. We realized a net cash loss of approximately $22.9 million on the hedging transactions that will be recognized on a pro rata basis as an increase in our reported interest expense over ten years of the total 15‑year notes.

At ~~September 30, 2017,~~March 31, 2021, we had ~~$2,798.0~~$4,373.0 million of~~corporate-related~~ corporate‑related borrowings outstanding under separate note purchase agreements entered into during the period from ~~2007~~2011 to ~~2017, and~~2021, no borrowings outstanding under our credit facility, $151.3 million outstanding under our Premium Financing Debt Facility and a cash and cash equivalent balance of ~~$564.9~~$526.3 million. See Note 67 to our March 31, 2021 unaudited consolidated financial statements for a discussion of the terms of the note purchase agreements, the Credit Agreement and the Premium Financing Debt ~~Facility.~~

~~We completed a $275.0 million, private placement debt transaction in the second quarter of 2016, with a weighted average interest rate of 4.47%~~Facility. ~~In 2016, we entered into apre-issuance~~ interest rate hedging transaction related to the $175.0 million, ten year tranche, of the $275.0 million private placement debt. We realized a cash gain of approximately $1.0 million on the hedging transaction that will be recognized on a pro rata basis as a reduction in our reported interest expense over the life of the debt.

~~On November 30, 2016, we funded the $50.0 million 2016 maturity of our Series C note.~~

We completed a $100.0 million, private placement debt transaction in the fourth quarter of 2016, with an interest rate of 3.46%. A portion of the proceeds was used to fund the $50.0 million of private placement debt that matured on November 30, 2016.

~~- 58 -~~

~~We used the proceeds of these offerings to repay certain existing indebtedness.~~

Consistent with past practice, as of March 31, 2021, we ~~have~~had entered intopre-issuance hedging ~~transaction~~transactions of $350.0 million for 2021, $400.0 million for 2022 and $200.0 million ~~related to each of the 2018 and 2019, $100.0 million debt maturities.~~for 2023.

The note purchase agreements, the Credit Agreement and the Premium Financing Debt Facility contain various financial covenants that require us to maintain specified financial ratios. We were in compliance with these covenants at ~~September 30, 2017.~~March 31, 2021.

Dividends-Our board of directors determines our dividend policy. Our board of directors determines dividends on our common stock on a quarterly basis after considering our available cash from earnings, our anticipated cash needs and current conditions in the economy and financial markets.

In the ~~nine-month~~three-month period ended ~~September 30, 2017,~~March 31, 2021, we declared ~~$212.3~~$94.9 million in cash dividends on our common stock, or ~~$0.39~~$0.48 per common share, a 3%7% increase over the ~~nine-month~~three-month period ended ~~September 30, 2016.~~March 31, 2020. On ~~October 25, 2017,~~April 28, 2021, we announced a quarterly dividend for ~~fourth~~second quarter ~~2017~~2021 of ~~$0.39~~$0.48 per common share. This dividend level in ~~2017~~2021 will result in annualized net cash used by financing activities in ~~2017~~2021 of approximately ~~$281.8~~$374.6 million (based on the number of outstanding shares as of ~~September 30, 2017)~~March 31, 2021) or an anticipated increase in cash used of approximately ~~$9.6~~$27.2 million compared to ~~2016.~~2020. We make no assurances regarding the amount of any future dividend ~~payments.~~payments.

Shelf Registration Statement -On November 15, ~~2016,~~2019, we filed a shelf registration statement onForm S-3 with the SEC, registering the offer and sale from time to time, of an indeterminate amount of our common stock. The availability of the potential liquidity under this shelf registration statement depends on investor demand, market conditions and other factors. We make no assurances regarding when, or if, we will issue any shares under this registration statement. On ~~April 2, 2015,~~November 15, 2016, we also filed a shelf registration statement on FormS-4 with the SEC, registering ~~8.0~~10.0 million shares of our common stock that we may offer and issue from time to time in connection with the future acquisitions of other businesses, assets or securities. At ~~September 30, 2017, 0.3~~March 31, 2021, 3.7 million shares remained available for issuance under this registration statement. ~~On November 15, 2016, we filed another shelf registration statement on FormS-4~~ ~~with the SEC, registering an additional 10.0 million shares of our common stock, none of which had been issued as of September 30, 2017.~~

Common Stock Repurchases-We have in place a common stock repurchase plan, last amended by our board of directors in 2008, for up to ~~10,000,000 shares. During the three-month period ended September 30, 2017, we did not repurchase any~~10.0 million shares ~~under the plan (7.7~~ (7.3millionshares remain available). During the ~~nine-month period~~three-month periods ended ~~September 30, 2016,~~March 31, 2021 and 2020, we ~~repurchased 2.3 million~~did not repurchase shares of our common ~~stock at a cost of $101.0 million.~~stock. The plan authorizes the repurchase of our common stock at such times and prices

- 58 -

as we may deem advantageous, in transactions on the open market or in privately negotiated transactions. We are under no commitment or obligation to repurchase any particular number of shares, and the plan may be suspended at any time at our discretion. Funding for share repurchases may come from a variety of sources, including cash from operations, short-term or long-term borrowings under our Credit Agreement or other sources. See “Issuer Purchases of Equity Securities” below for more information regarding shares repurchased during the quarter.

Common Stock Issuances- Another source of liquidity to us is the issuance of our common stock pursuant to our stock option and employee stock purchase plans. Proceeds from the issuance of common stock under these plans for the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, were ~~$50.2~~$37.2 million and ~~$36.8~~$23.9 million, respectively. On May 16, 2017, our stockholders approved the 2017 Long-Term Incentive Plan (which we refer to as the LTIP), which replaced our previous stockholder-approved 2014 Long-Term Incentive Plan. All of our officers, employees and non-employee directors are eligible to receive awards under the LTIP. Awards which may be granted under the LTIP includenon-qualified and incentive stock options, stock appreciation rights, restricted stock units and performance units, any or all of which may be made contingent upon the achievement of performance criteria. Stock options with respect to ~~16.1~~9.3 million shares (less any shares of restricted stock issued under the LTIP – ~~4.0~~1.8 million shares of our

~~- 59 -~~

common stock were available for this purpose as of ~~September 30, 2017)~~March 31, 2021) were available for grant under the LTIP at ~~September 30, 2017.~~March 31, 2021. Our employee stock purchase plan allows our employees to purchase our common stock at 95% of its fair market value. Proceeds from the issuance of our common stock related to these plans have contributed favorably to net cash provided by financing activities in the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, and we believe this favorable trend will continue in the foreseeable future.

Outlook -We believe that we have sufficient capital and access to additional capital to meet our short- and long-term cash flow needs.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks in our day to day operations. Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest and foreign currency exchange rates and equity prices. The following analyses present the hypothetical loss in fair value of the financial instruments held by us at ~~September 30, 2017~~March 31, 2021 that are sensitive to changes in interest rates. The range of changes in interest rates used in the analyses reflects our view of changes that are reasonably possible over a~~one-year~~ one‑year period. This discussion of market risks related to our consolidated balance sheet includes estimates of future economic environments caused by changes in market risks. The effect of actual changes in these market risk factors may differ materially from our estimates. In the ordinary course of business, we also face risks that are either nonfinancial or unquantifiable, including credit risk and legal risk. These risks are not included in the following analyses.

Our invested assets are primarily held as cash and cash equivalents, which are subject to various market risk exposures such as interest rate risk. The fair value of our portfolio of cash and cash equivalents at ~~September 30, 2017~~March 31, 2021 approximated its carrying value due to its short-term duration. We estimated market risk as the potential decrease in fair value resulting from a hypothetical~~one-percentage~~ one‑percentage point increase in interest rates for the instruments contained in the cash and cash equivalents investment portfolio. The resulting fair values were not materially different from ~~the~~their carrying values at ~~September 30, 2017.~~March 31, 2021.

At ~~September 30, 2017,~~March 31, 2021, we had ~~$2,798.0~~$4,373.0 million of borrowings outstanding under our various note purchase agreements. The aggregate estimated fair value of these borrowings at ~~September 30, 2017~~March 31, 2021 was ~~$2,922.4~~$4,845.6 million due to their~~long-term~~ long‑term duration and fixed interest rates associated with these debt obligations. No active or observable market exists for our private placement 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

~~- 60 -~~

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 ~~purposes~~purpose of ~~this~~our analysis, the average BBB rate was assumed to be the appropriate borrowing rate for ~~us based on our current estimated credit rating.~~us.

- 60 -

We estimated market risk as the potential impact on the value of the debt recorded in our consolidated balance sheet ~~resulting from~~based on a hypothetical~~one-percentage~~ one‑percentage point decrease in our weighted average borrowing rate at ~~September 30, 2017~~March 31, 2021 and the resulting fair values would have been ~~$321.7~~$783.5 million higher than their carrying value (or ~~$3,119.7~~$5,156.5 million). We estimated market risk as the potential impact on the value of the debt recorded in our consolidated balance sheet resulting from a hypothetical~~one-percentage~~ one‑percentage point increase in our weighted average borrowing rate at ~~September 30, 2017~~March 31, 2021 and the resulting fair values would have been ~~$57.0~~$188.2 million ~~lower~~higher than their carrying value (or ~~$2,741.0~~$4,561.2 million).

At ~~September 30, 2017,~~March 31, 2021, we had $75.0 million of borrowings outstanding under our Credit Agreement. The fair value of these borrowings approximate their carrying value due to their short-term duration and variable interest rates associated with these debt obligations. Market risk is estimated as the potential increase in fair value resulting from a hypothetical~~one-percentage~~ ~~point decrease in our weighted average short-term borrowing rate at September 30, 2017, and the resulting fair value is not materially different from their carrying value.~~

~~At September 30, 2017, we had $156.4~~$151.3 million of borrowings outstanding under our Premium Financing Debt Facility. The fair value of these borrowings approximate their carrying value due to their short-term duration and variable interest rates associated with these debt obligations. Market risk is estimated as the potential increase in fair value resulting from a hypothetical~~one-percentage~~ one‑percentage point decrease in our weighted average short-term borrowing rate at ~~September 30, 2017,~~March 31, 2021, and the resulting fair value is not materially different from their carrying value.

We are subject to foreign currency exchange rate risk primarily from one of our larger U.K. based brokerage subsidiaries that incurs expenses denominated primarily in British pounds while receiving a substantial portion of its revenues in U.S. dollars. Please see Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2020 for additional information regarding potential foreign exchange rate risks arising from Brexit. In addition, we are subject to foreign currency exchange rate risk from our Australian, Canadian, Indian, Jamaican, New Zealand, Norwegian, Singaporean and various Caribbean and ~~South~~Latin American operations because we transact business in their local denominated currencies. Foreign currency gains (losses) related to this market risk are recorded in earnings before income taxes as transactions occur. Assuming a hypothetical adverse change of 10% in the average foreign currency exchange rate for the ~~nine-month~~three-month period ended ~~September 30, 2017~~March 31, 2021 (a weakening of the U.S. dollar), earnings before income taxes would have increased by approximately ~~$9.1~~$16.3 million. Assuming a hypothetical favorable change of 10% in the average foreign currency exchange rate for the ~~nine-month~~three-month period ended ~~September 30, 2017~~March 31, 2021 (a strengthening of the U.S. dollar), earnings before income taxes would have decreased by approximately ~~$3.4~~$4.5 million. We are also subject to foreign currency exchange rate risk associated with the translation of local currencies of our foreign subsidiaries into U.S. dollars. We manage the balance sheets of our foreign subsidiaries, where practical, such that foreign liabilities are matched with equal foreign assets, maintaining a “balanced book” which minimizes the effects of currency fluctuations. However, our consolidated financial position is exposed to foreign currency exchange risk related to intra-entity loans between our U.S. based subsidiaries and ournon-U.S. based subsidiaries that are denominated in the respective local foreign currency. A transaction that is in a foreign currency is first remeasured at the entity’s functional (local) currency, where applicable, (which is an adjustment to consolidated earnings) and then translated to the reporting (U.S. dollar) currency (which is an adjustment to consolidated stockholders’ equity) for consolidated reporting purposes. If the transaction is already denominated in the foreign entity’s functional currency, only the translation to U.S. dollar reporting is necessary. The remeasurement process required by U.S. GAAP for such foreign currency loan transactions will give rise to a consolidated unrealized foreign exchange gain or loss, which could be material, that is recorded in accumulated other comprehensive earnings (loss).

Historically, we have not entered into derivatives or other similar financial instruments for trading or speculative purposes. However, with respect to managing foreign currency exchange rate risk in India, Norway and the U.K., we have periodically purchased financial instruments ~~when market opportunities arose~~ to minimize our exposure to this risk. During the ~~nine-month~~three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we had several monthly put/call options in place with an external financial institution that are designed to hedge a significant portion of our future U.K. currency

~~- 61 -~~

revenues ~~(in 2017) and disbursements (in 2016)~~ through various future payment dates. In addition, during the~~nine-month~~ three-month periods ended ~~September 30, 2017~~March 31, 2021 and ~~2016,~~2020, we had several monthly put/call options in place with an external financial institution that were designed to hedge a significant portion of our Indian currency disbursements through various future payment dates. Although these hedging strategies were designed to protect us against significant U.K. and Indian currency exchange rate movements, we are still exposed to some foreign currency exchange rate risk for the portion of the payments and currency exchange rate that are unhedged. All of these hedges are accounted for in accordance with ASC Topic 815, “Derivatives and Hedging”, and periodically are tested for effectiveness in accordance with such guidance. In the scenario where such hedge does not pass the effectiveness test, the hedge will bere-measured at the stated point and the appropriate loss, if applicable, would be recognized. In the ~~nine-month~~three-month period ended ~~September 30, 2017~~March 31, 2021 there has been no such effect on our financial presentation. The impact of these hedging strategies was not material to our unaudited consolidated financial statements for the ~~nine-month periods~~three-month period ended ~~September 30, 2017 and 2016.~~March 31, 2021. See Note 1413 to our unaudited consolidated financial statements for the changes in fair value of ~~the~~these derivative instruments reflected in comprehensive earnings at ~~September 30, 2017.~~March 31, 2021.

Controls and Procedures

We carried out an evaluation required by the Exchange Act, under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rule13a-15(e) of the ~~1934~~Exchange Act, as of the end of the period covered by this report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the ~~1934~~Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

During the most recent fiscal quarter, there has not occurred any change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. Management does not expect, however, that our disclosure controls and procedures will prevent or detect all ~~error~~errors and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within ~~the~~our Company have been detected.

Amounts in this column include shares of our common stock purchased by the trustees of ~~rabbi~~ trusts established under our Deferred Equity Participation Plan, including ~~sub - plans~~sub-plans (which we refer to as the DEPP), our Deferred Cash Participation Plan (which we refer to as the DCPP) and our Supplemental Savings and Thrift Plan (which we refer to as the Supplemental Plan), respectively. These plans are considered to be unfunded for purposes of federal tax law since the assets of these trusts are available to our creditors in the event of our financial insolvency. The DEPP is an unfunded, ~~non - qualified~~non-qualified deferred compensation plan that generally provides for distributions to certain of our key executives when they reach age 62 or upon or after their actual retirement. Under ~~sub - plans~~sub-plans of the DEPP for certain production staff, the plan generally provides 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. See Note 910 to the March 31, 2021 unaudited consolidated financial statements in this report for more information regarding the DEPP. The DCPP is an unfunded, ~~non - qualified~~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 terms of the DEPP and the DCPP, we may contribute cash to the rabbi trust and instruct the trustee to acquire a specified number of shares of our common stock on the open market or in privately negotiated transactions. In the ~~third~~first quarter of ~~2017,~~2021, we instructed the ~~rabbi~~ trustee for the DEPP and the DCPP to reinvest dividends ~~paid into the plans in~~on shares of our common stock held by these trusts and to purchase our common stock using ~~the~~ cash that ~~was funded into these plans~~we contributed to the DCPP related to ~~the 2017~~2021 awards under the ~~DEPP sub - plans.~~DCPP. The Supplemental Plan is an unfunded, ~~non - qualified~~non-qualified deferred compensation plan that allows certain highly compensated employees to defer ~~amounts,~~compensation, including company match amounts, on a ~~before - tax~~before-tax basis or ~~after -~~ after‑tax basis. Under the terms of the Supplemental Plan, all ~~cash deferrals and company match~~ amounts credited to an employee’s account may be deemed invested, at the employee’s election, in a number of investment options that include various mutual funds, an annuity product and a fund representing our common stock. When an employee elects to ~~deem his~~have some or ~~her~~all of the amounts credited to the employee’s account under the Supplemental Plan deemed to be invested in the fund representing our common stock, the trustee of the ~~rabbi~~ trust for the Supplemental Plan purchases shares of our common stock in a number sufficient to ensure that the trust holds a number of shares of our common stock with a value equal to all equivalent to the ~~amount~~amounts deemed invested in the fund representing our common stock. We want to ensure that at the time when an employee becomes entitled to a distribution under the terms of the Supplemental Plan, any amounts deemed to be invested in the fund representing our common stock are distributed in the form of shares of our common stock held by the trust. We established the ~~rabbi~~ trusts for the DEPP, the DCPP and the Supplemental Plan to assist us in discharging our deferred compensation obligations under these plans. All assets of ~~the rabbi~~these trusts, including any shares of our common stock purchased by the trustees, remain, at all times, assets of the Company, subject to the claims of our ~~creditors.~~creditors in the event of our financial insolvency. The terms of the DEPP, the DCPP and the Supplemental Plan do not provide for a specified limit on the number of shares of common stock that may be purchased by the respective trustees of the ~~rabbi~~ trusts.

We have a common stock repurchase plan that the board of directors adopted on May 10, 1988 and has periodically amended since that date to authorize additional shares for repurchase (the last amendment was on January 24, 2008 and approved the repurchase of 10,000,000 shares). The repurchase plan has no expiration date and we are under no commitment or obligation to repurchase any particular amount of our common stock under the plan. At our discretion, we may suspend the repurchase plan at any time.

~~Other Information~~

~~Disclosure pursuant to Section 13(r) of the Exchange Act~~

In third quarter 2017, our U.K. domiciled subsidiary, Arthur J. Gallagher (UK) Limited, and our Norway domiciled subsidiary, Bergvall Marine AS, acted as insurance broker and advised clients in obtaining insurance coverage for activities related to Iran’s oil, gas and petroleum industries. These subsidiaries assisted clients in obtaining insurance, reinsurance and retrocession coverage for a variety of activities in Iran, including insurance coverage for:

~~The supply and transport of oil, crude oil, heavy fuel oil and gas to and from Iran;~~

Item 6.

Exhibits

~~The docking and loading of oil shipments in Iran;~~

~~The operation of vessels providing support services to offshore oil platforms that supply oil to Iran; and~~

~~Other closely related activities pertaining to the supply and transportation of oil to and from Iran.~~

~~On January 16, 2016, the U.S. lifted the nuclear-related “secondary sanctions” imposed against Iran. In connection~~Filed with this event, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) issued General License H, which authorizes U.S.-owned or U.S.-controlled foreign entities to engage in certain transactions involving Iran that would otherwise be prohibited by section 560.215 of the Iranian Transactions and Sanctions Regulations.Form 10‑Q

The activities described above were conducted in full compliance with General License H. Our subsidiaries generated total gross revenue of approximately $11,478 (in actual dollars) and net profit of approximately $2,296 (in actual dollars) from these activities.

~~Our subsidiaries intend to continue acting as an insurance broker in connection with insurance coverages authorized by General License H.~~

In June 2014, we acquired a business in the U.K. that, beginning in 2011, had assisted its client, Bimeh Iran Insurance Company (UK) Limited (Bimeh), obtain certain insurance policies. In March 2014, the predecessor business placed a~~12-month~~ employers liability policy for Bimeh, with a premium of £371. In March 2015, after the acquisition, one of our U.K. subsidiaries assisted Bimeh with the renewal of the policy for a further 12 months, at the same premium of £371 plus a £50 administrative fee (generating total gross revenue for our U.K. subsidiary of approximately $117 and net profit of approximately $23). The policy was not renewed when it expired in March 2016, and Bimeh is no longer a client of our U.K. subsidiary.
