INFORMATION REGARDING FORWARD-LOOKING DISCLOSURE

This quarterly report on Form 10-Q contains forward-looking statements. Statements in this report that are not historical facts, including statements regarding goals, intentions, and expectations as to future plans, trends, events, or future results of operations or financial position, constitute forward-looking statements. Without limiting the generality of the foregoing, words such as “may,” “will,” “expect,” “believe,” “anticipate,” “estimate,” “project,” “forecast,” “plan,” “intend,” “could,” “would,” “should,” “estimate,” “will likely result” or comparable terminology are intended to identify forward-looking statements. Forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties, which could cause our actual results and outcomes to differ materially from those reflected in the forward-looking statements.

Actual results and outcomes could differ materially for a variety of reasons, including, among others:

•the effects of a challenging economy on the demand for our advertising and marketing services, on our clients’ financial condition and on our business or financial condition;

•our ability to attract new clients and retain existing clients;

•our ability to retain and attract key employees;

•the impacts of the COVID-19 pandemic, including potential developments like the emergence of more transmissible or virulent coronavirus variants, and associated mitigation measures, such as restrictions on businesses, social activities and travel, on the economy, our clients and demand for our services;

•risks associated with the effects of global, national and regional economic and political conditions, including counterparty risks and fluctuations in interest rates, inflation rates and currency exchange rates;

•the economic or business impact of military or political conflict in key markets;

•risks associated with assumptions we make in connection with our critical accounting estimates, including changes in assumptions associated with any effects of a challenging economy;

•potential adverse effects if we are required to recognize impairment charges or other adverse accounting-related developments;

•developments from changes in the regulatory and legal environment for advertising and marketing services companies around the world, including laws and regulations related to data protection and consumer privacy; and

•the impact on our operations of general or directed cybersecurity events.

Investors should carefully consider the foregoing factors and the other risks and uncertainties that may affect our business, including those outlined under Item 1A, Risk Factors, in our most recent annual report on Form 10-K and our quarterly reports on Form 10-Q. Investors are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date they are made. We undertake no obligation to update or revise publicly any of them in light of new information, future events, or otherwise.

Notes to Consolidated Financial Statements

(Amounts in Millions, Except Per Share Amounts)

(Unaudited)

Note 1:  Basis of Presentation

The unaudited Consolidated Financial Statements have been prepared by The Interpublic Group of Companies, Inc. and its subsidiaries (the “Company,” “IPG,” “we,” “us” or “our”) in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting interim financial information on Form 10-Q. Accordingly, they do not include certain information and disclosures required for complete financial statements. The effects of heightened macroeconomic uncertainty have impacted and may continue to impact our results of operations, cash flows and financial position. The Company’s Consolidated Financial Statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts of assets and liabilities and related disclosures as of the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company believes it has used reasonable estimates and assumptions to assess the fair values of goodwill, long-lived assets and indefinite-lived intangible assets; assessment of the annual effective tax rate; valuation of deferred income taxes and allowance for expected credit losses on future uncollectible accounts receivable.

Actual results may differ from these estimates under different assumptions or conditions and further decline in macroeconomic conditions or increasing interest rates could have a negative impact on these estimates, including the fair value of certain assets. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”).

We conduct our business across three reportable segments described in Note 10. The three reportable segments are: Media, Data & Engagement Solutions ("MD&E"), Integrated Advertising & Creativity Led Solutions ("IA&C"), and Specialized Communications & Experiential Solutions ("SC&E").

Cost of services is comprised of the expenses of our revenue-producing reportable segments, MD&E, IA&C, and SC&E, including salaries and related expenses, office and other direct expenses and billable expenses, and includes an allocation of the centrally managed expenses from our "Corporate and Other" group. Office and other direct expenses include rent expense, professional fees, certain expenses incurred by our staff in servicing our clients and other costs directly attributable to client engagements.

Selling, general and administrative expenses are primarily the unallocated expenses from Corporate and Other, excluding depreciation and amortization.

Depreciation and amortization of fixed assets and intangible assets of the Company is disclosed as a separate operating expense.

Restructuring charges in 2023 consist of adjustments to the Company's restructuring actions taken in 2022 and 2020, and primarily relate to real estate actions which were designed to reduce our real estate footprint and to better align our cost structure with revenue, as discussed further in Note 5.

In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments, consisting only of normal and recurring adjustments necessary for a fair statement of the information for each period contained therein. Certain reclassifications and immaterial adjustments have been made to prior-period financial statements to conform to the current-period presentation, including the recast of certain prior period amounts to reflect the transfer of certain agencies between reportable segments.

Note 2:  Revenue

Disaggregation of Revenue

We have three reportable segments as of September 30, 2023: MD&E, IA&C and SC&E, as further discussed in Note 10. MD&E principally generates revenue from providing global media and communications services, digital services and products, advertising and marketing technology, e‐commerce services, data management and analytics, strategic consulting, and digital brand experience. IA&C principally generates revenue from providing advertising, corporate and brand identity services, and strategic consulting. SC&E generates revenue from providing best-in-class global public relations and communications services, events, sports and entertainment marketing, and strategic consulting.

Our agencies are located in over 100 countries, including every significant world market. Our geographic revenue breakdown is listed below.

to advance consideration received from customers under the terms of our contracts primarily related to reimbursements of third-party expenses, whether we act as principal or agent, and to a lesser extent, periodic retainer fees, both of which are generally recognized shortly after billing.

The majority of our contracts are for periods of one year or less with the exception of our data management contracts. For those contracts with a term of more than one year, we had approximately $780.4 of unsatisfied performance obligations as of September 30, 2023, which will be recognized as services are performed over the remaining contractual terms through 2028.

Debt Transactions

5.375% Senior Notes due 2033

On June 8, 2023, we issued a total of $300.0 in aggregate principal amount of 5.375% unsecured senior notes (the "5.375% Senior Notes") due June 15, 2033. Upon issuance, the 5.375% Senior Notes were reflected in our unaudited Consolidated Balance Sheets at $292.9, net of discount of $3.8 and net of capitalized debt issuance costs, including commissions and offering expenses of $3.3, both of which will be amortized in interest expense through the maturity date using the effective interest method. Interest is payable semi-annually in arrears on June 15th and December 15th of each year, commencing on December 15, 2023.

Credit Agreement

We maintain a committed corporate credit facility, originally dated as of July 18, 2008, which has been amended and restated from time to time (the "Credit Agreement"). We use our Credit Agreement to increase our financial flexibility, to provide letters of credit primarily to support obligations of our subsidiaries and to support our commercial paper program. On November 1, 2021, we amended and restated the Credit Agreement. As amended, among other things, the maturity date of the Credit Agreement was extended to November 1, 2026 and the cost structure of the Credit Agreement was changed. The Credit Agreement continues to include a required leverage ratio of not more than 3.50 to 1.00, among other customary covenants, including limitations on our liens and the liens of our consolidated subsidiaries and limitations on the incurrence of subsidiary debt. At the election of the Company, the leverage ratio may be changed to not more than 4.00 to 1.00 for four consecutive quarters, beginning with the fiscal quarter in which there is an occurrence of one or more acquisitions with an aggregate purchase price of at least $200.0.

Notes to Consolidated Financial Statements – (continued)

(Amounts in Millions, Except Per Share Amounts)

(Unaudited)

The Credit Agreement is a revolving facility, under which amounts borrowed by us or any of our subsidiaries designated under the Credit Agreement may be repaid and reborrowed, subject to an aggregate lending limit of $1,500.0, or the equivalent in other currencies. The Company has the ability to increase the commitments under the Credit Agreement from time to time by an additional amount of up to $250.0, provided the Company receives commitments for such increases and satisfies certain other conditions. The aggregate available amount of letters of credit outstanding may decrease or increase, subject to a sublimit of $50.0, or the equivalent in other currencies. Our obligations under the Credit Agreement are unsecured. As of September 30, 2023, there were no borrowings under the Credit Agreement; however, we had $9.6 of letters of credit under the Credit Agreement, which reduced our total availability to $1,490.4. We were in compliance with all of our covenants in the Credit Agreement as of September 30, 2023.

Uncommitted Lines of Credit

We also have uncommitted lines of credit with various banks that permit borrowings at variable interest rates and that are primarily used to fund working capital needs. We have guaranteed the repayment of some of these borrowings made by certain subsidiaries. If we lose access to these credit lines, we would have to provide funding directly to some of our operations. As of September 30, 2023, the Company had uncommitted lines of credit in an aggregate amount of $869.9, under which we had outstanding borrowings of $31.0 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the third quarter of 2023 was $47.9 with a weighted-average interest rate of approximately 9.5%.

Commercial Paper

The Company is authorized to issue unsecured commercial paper up to a maximum aggregate amount outstanding at any time of $1,500.0. Borrowings under the program are supported by the Credit Agreement described above. Proceeds of the commercial paper are used for working capital and general corporate purposes, including the repayment of maturing indebtedness and other short-term liquidity needs. The maturities of the commercial paper vary but may not exceed 397 days from the date of issue. During the third quarter of 2023, there was no commercial paper activity and, as of September 30, 2023, there was no commercial paper outstanding.

Net (losses)/gains on sales of businesses – During the three and nine months ended September 30, 2023 and 2022, the amounts recognized were related to sales of businesses and the classification of certain assets and liabilities, consisting primarily of accounts receivable and accounts payable, as held for sale within our MD&E, IA&C, and SC&E reportable segments. The businesses sold and held for sale primarily represent unprofitable, non-strategic agencies which are expected to be sold within the next twelve months.

Other – During the three and nine months ended September 30, 2023, the amounts recognized were primarily related to pension and postretirement costs. During the three months ended September 30, 2022, the amounts recognized were primarily related to a cash gain from the sale of an equity investment. During the nine months ended September 30, 2022, the amounts recognized were primarily attributable to factors noted for the third quarter of 2022, partially offset by a non-cash loss related to the deconsolidation of a previously consolidated entity in which we maintain an equity interest in the second quarter of 2022.

Share Repurchase Programs

In February 2022, our Board of Directors (the "Board") reauthorized a program to repurchase, from time to time, up to $400.0 of our common stock.

On February 8, 2023, the Board authorized a share repurchase program to repurchase from time to time up to $350.0, excluding fees, of our common stock, which was in addition to any amounts remaining under the 2022 share repurchase program.

We may effect such repurchases through open market purchases, trading plans established in accordance with U.S. Securities and Exchange Commission ("SEC") rules, derivative transactions or other means. The timing and amount of repurchases in future periods will depend on market conditions and other funding requirements.

The following table presents our share repurchase activity under our share repurchase programs for the nine months ended September 30, 2023 and 2022.

Redeemable Non-controlling Interests

Many of our acquisitions include provisions under which the non-controlling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable non-controlling interests are adjusted quarterly, if necessary, to their estimated redemption value, but not less than their initial fair value. Any adjustments to the redemption value impact retained earnings or additional paid in capital, except for foreign currency translation adjustments.

The following table presents changes in our redeemable non-controlling interests.

Goodwill

Goodwill is the excess purchase price remaining from an acquisition after an allocation of purchase price has been made to identifiable assets acquired and liabilities assumed based on estimated fair values.

The Company transferred certain agencies between operating segments as of January 1, 2023 which resulted in certain changes to our reporting units and reportable segments. We have allocated goodwill to our reporting units using a relative fair value approach. In addition, we completed an assessment of any potential goodwill impairment for all impacted reporting units immediately prior and subsequent to the reallocation and determined that no impairment existed.

The following table sets forth details of changes in goodwill by reportable segment of the Company:

Note 6:  Income Taxes

For the three months ended September 30, 2023, our income tax expense was negatively impacted by tax expense associated with the change to our assertion regarding the permanent reinvestment of undistributed earnings attributable to certain foreign subsidiaries. For the nine months ended September 30, 2023, our income tax expense was positively impacted by a benefit of $64.2 related to the settlement of the 2017 and 2018 U.S. Federal income tax audit and excess tax benefits on employee share-based payments, the majority of which were recognized in the first quarter due to the timing of the vesting of awards.

We have various tax years under examination by tax authorities in various countries, and in various states, in which we have significant business operations. It is not yet known whether these examinations will, in the aggregate, result in our paying additional taxes. We believe our tax reserves are adequate in relation to the potential for additional assessments in each of the jurisdictions in which we are subject to taxation. We regularly assess the likelihood of additional tax assessments in those jurisdictions and, if necessary, adjust our reserves as additional information or events require.

With respect to all tax years open to examination by U.S. federal, various state and local, and non-U.S. tax authorities, we currently anticipate that total unrecognized tax benefits will decrease by an amount between $25.0 and $35.0 in the next twelve months, a portion of which will affect our effective income tax rate, primarily as a result of the settlement of tax examinations and the lapsing of statutes of limitations.

We are effectively settled with respect to U.S. federal income tax audits through 2018. With limited exceptions, we are no longer subject to state and local income tax audits for years prior to 2015 or non-U.S. income tax audits for years prior to 2010.

Note 7:  Incentive Compensation Plans

We issue stock-based compensation and cash awards to our employees under various plans established by the Compensation and Leadership Talent Committee of the Board of Directors (the "Compensation Committee") and approved by our stockholders. We issued the following stock-based awards under the 2019 Performance Incentive Plan (the "2019 PIP") during the nine months ended September 30, 2023.

	Awards	Weighted-average grant-date fair value (per award)
Restricted stock (units)	1.4	$	35.56
Performance-based stock (shares)	2.1	$	26.31
Total stock-based compensation awards	3.5

During the nine months ended September 30, 2023, the Compensation Committee granted performance cash awards under the 2019 PIP and restricted cash awards under the 2020 Restricted Cash Plan with a total annual target value of $46.1 and $17.4, respectively. Cash awards are expensed over the vesting period, which is typically three years for performance cash awards and two years or three years for restricted cash awards.

Note 9:  Employee Benefits

We have a defined benefit pension plan that covers certain U.S. employees (the “Domestic Pension Plan”). We also have numerous funded and unfunded plans outside the U.S. The Interpublic Limited Pension Plan in the U.K. is a defined benefit plan and is our most material foreign pension plan in terms of the benefit obligation and plan assets. Some of our domestic and foreign subsidiaries provide postretirement health benefits and life insurance to eligible employees and, in certain cases, their dependents. The domestic postretirement benefit plan is our most material postretirement benefit plan in terms of the benefit obligation. Certain immaterial foreign pension and postretirement benefit plans have been excluded from the table below.

The components of net periodic cost for the Domestic Pension Plan, the significant foreign pension plans and the domestic postretirement benefit plan are listed below.

	Domestic Pension Plan				Foreign Pension Plans				Domestic Postretirement Benefit Plan

The components of net periodic cost other than the service cost component are included in the line item “Other (expense) income, net” in the Consolidated Statements of Operations.

During the nine months ended September 30, 2023, we contributed $0.0 and $12.2 of cash to our domestic and foreign pension plans, respectively. For the remainder of 2023, we expect to contribute approximately $0.0 and $4.0 of cash to our domestic and foreign pension plans, respectively.

Note 10:  Segment Information

As of September 30, 2023, we have three reportable segments: MD&E, IA&C, and SC&E. We also report results for the "Corporate and other" group.

MD&E primarily provides, and is distinguished by innovative capabilities and scale in, global media and communications services, digital services and products, advertising and marketing technology, e‐commerce services, data management and analytics, strategic consulting, and digital brand experience. MD&E is comprised of IPG Mediabrands and Acxiom, as well as our digital and commerce specialist agencies, which include MRM, R/GA, and Huge.

IA&C primarily provides advertising, corporate and brand identity services, and strategic consulting. IA&C is distinguished by the leading role of complex integrations of ideation and the execution of advertising and creative campaigns across all communications channels that are foundational to client brand identities. IA&C is comprised of leading global networks and agencies that provide a broad range of services, including McCann Worldgroup, IPG Health, MullenLowe Group, Foote, Cone & Belding ("FCB"), and our domestic integrated agencies.

SC&E primarily provides best-in-class global public relations and other specialized communications services, events, sports and entertainment marketing, and strategic consulting. SC&E is comprised of agencies that provide a range of marketing services expertise, including Weber Shandwick, Golin, our sports, entertainment, and experiential agencies, and DXTRA Health.

In conjunction with the new reporting structure, prior period segment disclosures have been recast to reflect our new reportable segments, as well as the way performance is internally managed and monitored.

We continue to evaluate our financial reporting structure, and the profitability measure employed by our chief operating decision maker for allocating resources to operating divisions and assessing operating division performance is segment EBITA. Summarized financial information concerning our reportable segments is shown in the following table.

Note 11:  Fair Value Measurements

Authoritative guidance for fair value measurements establishes a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial Instruments that are Measured at Fair Value on a Recurring Basis

We primarily apply the market approach to determine the fair value of financial instruments that are measured at fair value on a recurring basis. There were no changes to our valuation techniques used to determine the fair value of financial instruments during the nine months ended September 30, 2023. The following tables present information about our financial instruments measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value.

1Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional non-controlling equity shares of consolidated subsidiaries. Fair value measurement of the obligations is based upon actual and projected operating performance targets as specified in the related agreements. The decrease in this balance of $19.2 from December 31, 2022 to September 30, 2023 is primarily due to payments related to our deferred acquisitions payments from prior-year acquisitions and valuation adjustments, partially offset by new acquisitions and the exercises of redeemable non-controlling interest. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities.

Financial Instruments that are not Measured at Fair Value on a Recurring Basis

The following table presents information about our financial instruments that are not measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

Our marketable securities are comprised of U.S. Treasury Securities with maturity dates of less than 1 year and are classified as held-to-maturity. Held-to-maturity investments are stated at amortized cost. The fair value of our marketable securities are measured based on quoted prices in active markets and are classified as Level 1.

Our long-term debt is comprised of senior notes and other notes payable. The fair value of our senior notes, which are traded over-the-counter, is based on quoted prices in markets that are not active. Therefore, these senior notes are classified as Level 2. Our other notes payable are not actively traded, and their fair value is not solely derived from readily observable inputs. The fair value of our other notes payable is determined based on a discounted cash flow model and other proprietary valuation methods, and therefore is classified as Level 3. See Note 3 for further information on our long-term debt.

The discount rates used as significant unobservable inputs in the Level 3 fair value measurements of our contingent acquisition obligations and long-term debt as of September 30, 2023 ranged from 3.0% to 6.0%.

Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis, primarily goodwill (Level 3), intangible assets, and property and equipment. Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment.

Note 12:  Commitments and Contingencies

Guarantees

As discussed in our 2022 Annual Report, we have guaranteed certain obligations of our subsidiaries relating principally to operating leases and uncommitted lines of credit of certain subsidiaries. As of September 30, 2023 and December 31, 2022, the amount of parent company guarantees on lease obligations was $725.0 and $797.3, respectively, the amount of parent company guarantees primarily relating to uncommitted lines of credit was $276.3 and $276.4, respectively, and the amount of parent company guarantees related to daylight overdrafts, primarily utilized to manage intra-day overdrafts due to timing of transactions under cash pooling arrangements without resulting in incremental borrowings, was $106.8 and $101.3, respectively. In the event of non-payment by the applicable subsidiary of the obligations covered by a guarantee, we would be obligated to pay the amounts covered by that guarantee. As of both September 30, 2023, and December 31, 2022 there were no material assets pledged as security for such parent company guarantees.

Legal Matters

We are involved in various legal proceedings, and subject to investigations, inspections, audits, inquiries and similar actions by governmental authorities arising in the normal course of business. The types of allegations that arise in connection with such legal proceedings vary in nature, but can include claims related to contract, employment, tax and intellectual property matters. We evaluate all cases each reporting period and record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount, or potential range, of loss can be reasonably estimated. In certain cases, we cannot reasonably estimate the potential loss because, for example, the litigation is in its early stages. While any outcome related to litigation or such governmental proceedings in which we are involved cannot be predicted with certainty, management believes that the outcome of these matters, individually and in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows.

Note 13:  Recent Accounting Standards

Accounting pronouncements not listed below were assessed and determined to be not applicable or are expected to have minimal impact on our Consolidated Financial Statements.

Derivatives and Hedging

In March 2022, the Financial Accounting Standards Board (the "FASB") issued amended guidance on hedge accounting which allows nonprepayable financial assets to be included in a closed portfolio hedge using the portfolio layer method, allowing for more consistent accounting over prepayable and nonprepayable hedges. The new guidance also allows multiple hedged layers to be designated for a single closed portfolio, further aligning hedge accounting with risk management strategies. We adopted the standard January 1, 2023, which did not have a significant impact on our financial statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to help you understand The Interpublic Group of Companies, Inc. and its subsidiaries (the “Company,” “IPG,” “we,” “us” or “our”). MD&A should be read in conjunction with our unaudited Consolidated Financial Statements and the accompanying notes included in this report and our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”), as well as our other reports and filings with the Securities and Exchange Commission (the “SEC”). Our 2022 Annual Report includes additional information about our significant accounting policies and practices as well as details about the most significant risks and uncertainties associated with our financial and operating results. Our MD&A includes the following sections:

EXECUTIVE SUMMARY provides a discussion about our strategic outlook, factors influencing our business and an overview of our results of operations.

RESULTS OF OPERATIONS provides an analysis of the consolidated and segment results of operations for the periods presented.

LIQUIDITY AND CAPITAL RESOURCES provides an overview of our cash flows, funding requirements, financing and sources of funds, and debt credit ratings.

CRITICAL ACCOUNTING ESTIMATES provides an update to the discussion in our 2022 Annual Report of our accounting policies that require critical judgment, assumptions and estimates.

RECENT ACCOUNTING STANDARDS, by reference to Note 13 to the unaudited Consolidated Financial Statements, provides a discussion of certain accounting standards that have been recently adopted or that have not yet been required to be implemented and may be applicable to our future operations.

NON-GAAP FINANCIAL MEASURE, provides a reconciliation of non-GAAP financial measure with the most directly comparable generally accepted accounting principles in the United States (“U.S. GAAP”) financial measures and sets forth the reasons we believe that presentation of the non-GAAP financial measure contained therein provides useful information to investors regarding our results of operations and financial condition.

EXECUTIVE SUMMARY

Our Business

We provide marketing, communications and business transformation services that help marketers and brands succeed in today's digital economy. Combining the power of creativity and technology, our 57,700 employees and operations span all major world markets. Our companies specialize in data, creativity, media, consulting, commerce, behavioral science and communications, producing marketing solutions for clients that range in scale from large global marketers to regional and local clients. Our comprehensive global services help marketers build brands, increase sales of their products and services, and gain market share.

Our capabilities span ideation to execution: growth, product and experience design; technology and experience platforms; creative, media and marketing strategy; and campaign, content and channel orchestration. The work we produce for our clients is specific to their unique needs. Our solutions vary from project-based activity involving one agency to long-term, fully integrated campaigns created by multiple IPG agencies working together. Our operations support the strategic position that marketers have access to the best and most appropriate resources within IPG to drive business success, and may access these capabilities from across the IPG network in a seamless model called Open Architecture®. With operations in over 100 countries, we can operate in a single region or deliver global integrated programs.

We operate in a media, consumer and technology ecosystem that continues to evolve at a rapid pace. Media channels continue to fragment, and clients face an increasingly complex consumer environment. To stay ahead of these challenges and to achieve our objectives, we have made and continue to make investments in creative, strategic and technology talent in areas including commerce, fast-growth digital marketing channels, high-growth geographic regions and strategic world markets. In addition, we consistently review opportunities within our Company to enhance our operations through acquisitions and strategic alliances and internal programs that encourage client-centric collaboration. As appropriate, we also develop relationships with technology and emerging media companies that are building leading-edge marketing tools that complement our agencies' skill sets and capabilities.

Home to some of the world’s best-known and most innovative communications specialists, IPG global brands include Acxiom, Craft, FCB, FutureBrand, Golin, Huge, Initiative, IPG Health, Jack Morton, Kinesso, MAGNA, Matterkind, McCann, Mediabrands, Mediahub, Momentum, MRM, MullenLowe Group, Octagon, R/GA, UM, Weber Shandwick and more.

Our financial goals include competitive organic growth of revenue before billable expenses and expansion of Adjusted EBITA margin, as defined and discussed within the Non-GAAP Financial Measure section of this MD&A, which we expect will further strengthen our balance sheet and total liquidity and increase value to our stakeholders. Accordingly, we remain focused on meeting the evolving needs of our clients while concurrently managing our cost structure. We continually seek greater efficiency in the delivery of our services, focusing on more effective resource utilization, including the productivity of our employees, real estate, information technology and shared services, such as finance, human resources and legal. The improvements we have made and continue to make in our financial reporting and business information systems in recent years allow us more timely and actionable insights from our global operations. Our disciplined approach to our balance sheet and liquidity provides us with a solid financial foundation and financial flexibility to manage and grow our business. We believe that our strategy and execution position us to meet our financial goals and to deliver long-term value to all of our stakeholders.

Current Market Conditions

In contrast to the robust business environment in 2022, the macroeconomic backdrop in 2023 has been more moderate. The impact of a slowing economy that we began to see toward the end of last year on the more cyclical parts of our business continued to weigh on the first nine months of the year, although certain business sectors and geographic regions continue to show resilience. The principal macroeconomic risks to our performance include the impact of any general or regional economic slowdown or contraction, the extent of inflation of labor costs and potential for labor shortages, inflationary pressures on our clients and their customers, the economic impacts of geopolitical conflict and uncertainty, and the impact of continuing and unpredictable supply chain disruptions across the global economy. See Item 1A, Risk Factors, in our most recent Annual Report on Form 10-K.

Our Financial Information

When we analyze period-to-period changes in our operating performance, we determine the portion of the change that is attributable to changes in foreign currency rates and the net effect of acquisitions and divestitures, and the remainder we call organic change, which indicates how our underlying business performed. We exclude the impact of billable expenses in analyzing our operating performance as the fluctuations from period to period are not indicative of the performance of our underlying businesses and have no impact on our operating income or net income.

The change in our operating performance attributable to changes in foreign currency rates is determined by converting the prior-period reported results using the current-period exchange rates and comparing these prior-period adjusted amounts to the prior-period reported results. Although the U.S. Dollar is our reporting currency, a substantial portion of our revenues and expenses are generated in foreign currencies. Therefore, our reported results are affected by fluctuations in the currencies in which we conduct our international businesses. Our exposure is mitigated as the majority of our revenues and expenses in any given market are generally denominated in the same currency. Both positive and negative currency fluctuations against the U.S. Dollar affect our consolidated results of operations, and the magnitude of the foreign currency impact to our operations related to each geographic region depends on the significance and operating performance of the region. Our results during the first nine months of 2023 were most adversely impacted by the strength of the U.S. Dollar against the Argentine Peso, Canadian Dollar and British Pound Sterling.

For purposes of analyzing changes in our operating performance attributable to the net effect of acquisitions and divestitures, transactions are treated as if they occurred on the first day of the quarter during which the transaction occurred. We continually evaluate our portfolio of businesses, and over the past several years, we have acquired companies that we believe will enhance our offerings and disposed of businesses that are not consistent with our strategic plan.

The metrics that we use to evaluate our financial performance include organic change in revenue before billable expenses as well as the change in certain operating expenses, and the components thereof, expressed as a percentage of consolidated revenue before billable expenses, as well as Adjusted EBITA. These metrics are also used by management to assess the financial performance of our reportable segments, MD&E, IA&C, and SC&E. In certain of our discussions, we analyze revenue before billable expenses by geographic region and by business sector, in which we focus on our top 500 clients, which typically constitute approximately 85% of our annual consolidated revenue before billable expenses.

Results for the three and nine months ended September 30, 2023, may not be indicative of the results that may be expected for the fiscal year ending December 31, 2023. The Consolidated Financial Statements and MD&A presented herein reflect the latest estimates and assumptions made by us that affect the reported amounts of assets and liabilities and related disclosures as

of the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. We believe we have used reasonable estimates and assumptions to assess the fair values of the Company’s goodwill, long-lived assets and indefinite-lived intangible assets; assessment of the annual effective tax rate; valuation of deferred income taxes and the allowance for expected credit losses on future uncollectible accounts receivable. If actual market conditions vary significantly from those currently projected, these estimates and assumptions could materially change resulting in adjustments to the carrying values of our assets and liabilities.

The following table presents a summary of our financial performance for the three and nine months ended September 30, 2023 and 2022.

Total revenue, which includes billable expenses, increased 1.5% during the third quarter of 2023. Our organic decrease of revenue before billable expenses was (0.4)% during the third quarter of 2023, compared to an organic increase of 5.6% during the third quarter of 2022. The decrease was due to lower spending from existing clients and net client losses in our technology & telecom and retail sectors, partially offset by increased spending from existing clients and net client wins in our auto & transportation, other, financial services, and healthcare sectors. During the third quarter of 2023, our Adjusted EBITA margin on revenue before billable expenses increased to 17.2% from 15.8% in the prior-year period as revenue before billable expenses increased, and our operating expenses, excluding billable expenses and amortization of acquired intangibles decreased. See further discussion below in the “Results of Operations” section.

Total revenue, which includes billable expenses, decreased (1.0)% during the first nine months of 2023.

RESULTS OF OPERATIONS

Consolidated Results of Operations – Three and Nine Months Ended September 30, 2023 Compared to Three and Nine Months Ended September 30, 2022

Revenue before billable expenses

Our revenue before billable expenses is directly impacted by the retention and spending levels of existing clients and by our ability to win new clients. Most of our expenses are recognized ratably throughout the year and are therefore less seasonal than revenue. Our revenue before billable expenses is typically lowest in the first quarter and highest in the fourth quarter, reflecting the seasonal spending of our clients.

The organic decrease of revenue before billable expenses was (0.4)% during the third quarter of 2023. The organic decrease in our domestic market was primarily due to revenue decreases at our advertising businesses and digital project-based offerings, partially offset by revenue increases at our media businesses. In our international markets, the 1.1% organic increase was driven by revenue increases at our media businesses, public relations agencies and experiential businesses and was most notable in our Continental Europe and Latin America regions, partially offset by revenue decreases at our digital project-based offerings across all regions.

Other Expense, Net

Results of operations for the three and nine months ended September 30, 2023 and 2022 include certain items that are not directly associated with our revenue-producing operations.

	Three months ended September 30,				Nine months ended September 30,

Net (losses)/gains on sales of businesses – During the three and nine months ended September 30, 2023 and 2022, the amounts recognized were related to sales of businesses and the classification of certain assets and liabilities, consisting primarily of accounts receivable and accounts payable, as held for sale within our MD&E, IA&C, and SC&E reportable segments. The businesses sold and held for sale primarily represent unprofitable, non-strategic agencies which are expected to be sold within the next twelve months.

Other – During the three and nine months ended September 30, 2023, the amounts recognized were primarily related to pension and postretirement costs. During the three months ended September 30, 2022, the amounts recognized were primarily related to a cash gain from the sale of an equity investment. During the nine months ended September 30, 2022, the amounts recognized were primarily attributable to factors noted for the third quarter of 2022, partially offset by a non-cash loss related to the deconsolidation of a previously consolidated entity in which we maintain an equity interest in the second quarter of 2022.

Provision for income taxes	$	91.5	$	76.4	$	135.9	$	209.2

Our tax rates are affected by many factors, including our worldwide earnings from various countries, changes in legislation and tax characteristics of our income. For the three months ended September 30, 2023, our income tax expense was negatively impacted by tax expense associated with the change to our assertion regarding the permanent reinvestment of undistributed earnings attributable to certain foreign subsidiaries. For the nine months ended September 30, 2023, our income tax expense was positively impacted by a benefit of $64.2 related to the settlement of the 2017 and 2018 U.S. Federal income tax audit and excess tax benefits on employee share-based payments, the majority of which were recognized in the first quarter due to the timing of the vesting of awards.

For the three and nine months ended September 30, 2022, our income tax expense was positively impacted by excess tax benefits on employee share-based payments, the majority of which were recognized in the first quarter due to the timing of the vesting of awards, partially offset by net losses on sales of businesses and the classification of certain assets as held for sale for which we received minimal tax benefit.

The organic decrease during the first nine months of 2023 was due to lower spending from existing clients and net client losses in our technology & telecom retail and financial services sectors, partially offset by net client wins in our auto & transportation sector. The (4.2)% organic decrease during the first nine months of 2023 in our domestic market was due to revenue decreases in our advertising businesses. In our international markets, the (0.4)% organic decrease was due to revenue decreases in our advertising businesses most notably in our Continental Europe and Asia Pacific regions, partially offset by revenue growth in our Other Region, led by the Middle East, and Latin America regions.

Segment EBITA margin decreased during the third quarter of 2023 compared to the prior-year period, as the decrease in revenue before billable expenses, as discussed above, exceeded the overall decrease in our operating expenses, excluding billable expenses and amortization of acquired intangibles. The decrease in salaries and related expenses, as compared to the prior-year period, was primarily driven by decreases in performance-based incentive expense, temporary help expense and base salaries, benefits and tax. Office and other direct expense decreased mainly due to decreases in employment costs and occupancy expense, partially offset by foreign currency losses and increases in professional consulting fees.

CORPORATE AND OTHER

Corporate and Other is primarily comprised of selling, general and administrative expenses including corporate office expenses as well as shared service center and certain other centrally managed expenses that are not fully allocated to operating divisions; salaries, long-term incentives, annual bonuses and other miscellaneous benefits for corporate office employees; professional fees related to internal control compliance, financial statement audits and legal, information technology and other consulting services that are engaged and managed through the corporate office; and rental expense for properties occupied by corporate office employees. A portion of centrally managed expenses is allocated to operating divisions based on a formula that uses the planned revenues of each of the operating units. Amounts allocated also include specific charges for information technology-related projects, which are allocated based on utilization.

During the third quarter of 2023, Corporate and Other expenses decreased by $1.7 compared to the prior-year period to $18.3, primarily attributable to a decrease in selling, general and administrative expenses, which is discussed in the Results of Operations section. During the first nine months of 2023, Corporate and Other expenses decreased by $14.7 compared to the prior-year period to $47.2, primarily attributable to factors similar to those noted for the second quarter of 2023.

LIQUIDITY AND CAPITAL RESOURCES

CASH FLOW OVERVIEW

The following table summarizes key financial data relating to our liquidity, capital resources and uses of capital.

	Nine months ended September 30,
Cash Flow Data	2023		2022
Net income	$	646.5	$	650.2

1Consist primarily of depreciation and amortization of fixed assets and intangible assets, amortization of restricted stock and other non-cash compensation and net losses on sales of businesses.

2Reflects changes in accounts receivable, prepaid expenses, other current assets, accounts payable, accrued liabilities and contract liabilities.

Operating Activities

The presentation of the three components of net cash provided by operating activities above reflects the manner in which management views and analyzes this information. Management believes this presentation is useful as it presents cash provided by operating activities separately from the impact of changes in working capital, which is seasonal in nature and is impacted by

39

Management’s Discussion and Analysis of Financial Condition and Results of Operations - (continued)

(Amounts in Millions, Except Per Share Amounts)

(Unaudited)

the timing of media buying on behalf of our clients. Additionally, we view changes in other non-current assets and liabilities separately, as these items are not impacted by the factors described below.

Due to the seasonality of our business, we typically use cash from working capital in the first nine months of a year, with the largest impact in the first quarter, and generate cash from working capital in the fourth quarter, driven by the seasonally strong media spending by our clients. Quarterly and annual working capital results are impacted by the fluctuating annual media spending budgets of our clients as well as their changing media spending patterns throughout each year across various countries.

The timing of media buying on behalf of our clients across various countries affects our working capital and operating cash flow and can be volatile. In most of our businesses, our agencies enter into commitments to pay production and media costs on behalf of clients. To the extent possible, we pay production and media charges after we have received funds from our clients. The amounts involved, which substantially exceed our revenues, primarily affect the level of accounts receivable, accounts payable, accrued liabilities and contract liabilities. Our assets include both cash received and accounts receivable from clients for these pass-through arrangements, while our liabilities include amounts owed on behalf of clients to media and production suppliers. Our accrued liabilities are also affected by the timing of certain other payments. For example, while annual cash incentive awards are accrued throughout the year, they are generally paid during the first quarter of the subsequent year.

Net cash used in operating activities during the first nine months of 2023 decreased to $340.1 from $658.8 in the first nine months of 2022, primarily attributable to a decrease in working capital usage of $424.5. Working capital use was primarily impacted by the spending levels of our clients and variation in the timing of collections and payments around the reporting period.

Investing Activities

Net cash used in investing activities during the first nine months of 2023 was $204.3, which was an increase of $78.1 as compared to the first nine months of 2022, primarily driven by an increase in purchases of short-term marketable securities of $97.6, partially offset by an increase in net proceeds from investments of $19.1 as compared to the first nine months of 2022. Payments for capital expenditures increased to $127.1 from $118.5 in the first nine months of 2023 and 2022, respectively, primarily attributable to higher spending on computer software, partially offset by decreased spending on computer hardware.

Financing Activities

Net cash used in financing activities during the first nine months of 2023 was $390.0, primarily driven by the payment of common stock dividends of $361.2 and common stock repurchases of $219.0, partially offset by net proceeds of $296.3 from the issuance of our $300.0 aggregate principal amount of 5.375% unsecured senior notes due 2033 (the "5.375% Senior Notes"). See Note 3 in Item 1, Financial Statements, for further information.

Net cash used in financing activities during the first nine months of 2022 was $652.9, primarily driven by the payment of common stock dividends of $345.1 and common stock repurchases of $221.6.

Foreign Exchange Rate Changes

The effect of foreign exchange rate changes on cash, cash equivalents and restricted cash included in the unaudited Consolidated Statements of Cash Flows resulted in a net decrease of $35.0 during the first nine months of 2023. The decrease was primarily a result of the U.S. Dollar being stronger than several foreign currencies, including the Australian Dollar, Argentine Peso, British Pound Sterling and Euro as of September 30, 2023 as compared to December 31, 2022.

LIQUIDITY OUTLOOK

We expect our cash flow from operations and existing cash and cash equivalents to be sufficient to meet our anticipated operating requirements at a minimum for the next twelve months. We also have a commercial paper program, a committed corporate credit facility, and uncommitted lines of credit to support our operating needs. Borrowings under our commercial paper program are supported by our committed corporate credit agreement. We continue to maintain a disciplined approach to managing liquidity, with flexibility over significant uses of cash, including our capital expenditures, cash used for new acquisitions, our common stock repurchase program and our common stock dividends.

From time to time, we evaluate market conditions and financing alternatives for opportunities to raise additional funds or otherwise improve our liquidity profile, enhance our financial flexibility and manage market risk. Our ability to access the capital markets depends on a number of factors, which include those specific to us, such as our credit ratings, and those related to the financial markets, such as the amount or terms of available credit. There can be no guarantee that we would be able to access new sources of liquidity, or continue to access existing sources of liquidity, on commercially reasonable terms, or at all.

Funding Requirements

Our most significant funding requirements include our operations, non-cancelable operating lease obligations, capital expenditures, acquisitions, common stock dividends, taxes, and debt service. Additionally, we may be required to make payments to minority shareholders in certain subsidiaries if they exercise their options to sell us their equity interests.

Notable funding requirements include:

•Debt service – Our 4.200% Senior Notes in aggregate principal amount of $250.0 mature on April 15, 2024. We expect to use available cash, as well as credit available under our commercial paper and short-term debt lines as needed to fund the principal repayment. As of September 30, 2023, we had outstanding short-term borrowings of $31.0 from our uncommitted lines of credit used primarily to fund short-term working capital needs. The remainder of our debt is primarily long-term, with maturities scheduled from 2028 through 2048.

•Acquisitions – We paid cash of $2.6, net of cash acquired, for acquisitions completed in the first nine months of 2023, as well as $3.7 in relation to adjustments made to upfront payments related to prior year acquisitions. We paid deferred payments of $15.6 for prior-year acquisitions as well as ownership increases in our consolidated subsidiaries in the first nine months of 2023. In addition to potential cash expenditures for new acquisitions, we expect to pay approximately $2.0 over the next twelve months related to all completed acquisitions as of September 30, 2023. We may also be required to pay approximately $5.0 related to redeemable non-controlling interest held by minority shareholders, if exercised, over the next twelve months. We will continue to evaluate strategic opportunities to grow and continue to strengthen our market position, particularly in our digital and marketing services offerings, and to expand our presence in high-growth and key strategic world markets.

•Dividends – In the first nine months of 2023, we paid a quarterly cash dividend of $0.310 per share on our common stock, which corresponded to an aggregate dividend payment of $361.2. Assuming we pay a quarterly dividend of $0.310 per share, and there is no significant change in the number of outstanding shares as of September 30, 2023, we would expect to pay approximately $475.0 over the next twelve months. Whether to declare and the amount of any such future dividend is at the discretion of our Board of Directors (the "Board") and will depend upon factors such as our earnings, financial position and cash requirements.

Share Repurchase Programs

In February 2022, our Board reauthorized a program to repurchase, from time to time, up to $400.0 of our common stock. In February 2023, the Board authorized a share repurchase program to repurchase from time to time up to $350.0, excluding fees, of our common stock, which was in addition to any amounts remaining under the 2022 share repurchase program. We fully utilized the 2022 share repurchase program during the second quarter of 2023. As of September 30, 2023, $211.2, excluding fees, remains available for repurchase under the 2023 share repurchase program. We may effect such repurchases through open market purchases, trading plans established in accordance with U.S. Securities and Exchange Commission ("SEC") rules, derivative transactions or other means. There is no expiration date associated with the 2023 share repurchase program.

FINANCING AND SOURCES OF FUNDS

Substantially all of our operating cash flow is generated by our agencies. Our cash balances are held in numerous jurisdictions throughout the world, including at the holding company level. Below is a summary of our sources of liquidity.

Credit Agreement

We maintain a committed corporate credit facility, originally dated as of July 18, 2008, which has been amended and restated from time to time (the “Credit Agreement”). We use our Credit Agreement to increase our financial flexibility, to provide letters of credit primarily to support obligations of our subsidiaries and to support our commercial paper program. On November 1, 2021, we amended and restated the Credit Agreement. As amended, among other things, the maturity date of the Credit Agreement was extended to November 1, 2026 and the cost structure of the Credit Agreement was changed. The Credit Agreement continues to include a required leverage ratio of not more than 3.50 to 1.00, among other customary covenants, including limitations on our liens and the liens of our consolidated subsidiaries and limitations on the incurrence of subsidiary debt. At the election of the Company, the leverage ratio may be changed to not more than 4.00 to 1.00 for four consecutive quarters, beginning with the fiscal quarter in which there is an occurrence of one or more acquisitions with an aggregate purchase price of at least $200.0. The Credit Agreement is a revolving facility, under which amounts borrowed by us or any of our subsidiaries designated under the Credit Agreement may be repaid and reborrowed, subject to an aggregate lending limit of $1,500.0, or the equivalent in other currencies. The Company has the ability to increase the commitments under the Credit Agreement from time to time by an additional amount of up to $250.0, provided the Company receives commitments for such increases and satisfies certain other conditions. The aggregate available amount of letters of credit outstanding may decrease or increase, subject to a sublimit of $50.0, or the equivalent in other currencies. Our obligations under the Credit Agreement are unsecured. As of September 30, 2023, there were no borrowings under the Credit Agreement; however, we had $9.6 of letters of credit under the Credit Agreement, which reduced our total availability to $1,490.4.

We were in compliance with all of our covenants in the Credit Agreement as of September 30, 2023. Management utilizes Credit Agreement EBITDA, which is a non-GAAP financial measure, as well as the amounts shown in the table below, calculated as required by the Credit Agreement, in order to assess our compliance with such covenants.

	Four Quarters Ended		Four Quarters Ended
Financial Covenant	September 30, 2023	Credit Agreement EBITDA Reconciliation	September 30, 2023
Leverage ratio (not greater than) 1	3.50x	Net income available to IPG common stockholders	$	932.4
Actual leverage ratio	1.84x	Non-operating adjustments 2	388.0
		Operating income	1,320.4
		Add:
		Depreciation and amortization	333.6
		Other non-cash charges reducing operating income	85.5
		Credit Agreement EBITDA 1	$	1,739.5

1The leverage ratio is defined as debt as of the last day of such fiscal quarter to EBITDA (as defined in the Credit Agreement) for the four quarters then ended.

2Includes adjustments of the following items from our Consolidated Statements of Operations: provision for income taxes, total (expenses) and other income, equity in net income of unconsolidated affiliates, and net income attributable to non-controlling interests.

Uncommitted Lines of Credit

We also have uncommitted lines of credit with various banks that permit borrowings at variable interest rates and that are primarily used to fund working capital needs. We have guaranteed the repayment of some of these borrowings made by certain subsidiaries. If we lose access to these credit lines, we would have to provide funding directly to some of our operations. As of September 30, 2023, the Company had uncommitted lines of credit in an aggregate amount of $869.9, under which we had outstanding borrowings of $31.0 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the third quarter of 2023 was $47.9 with weighted-average interest rate of approximately 9.5%.

Commercial Paper

The Company is authorized to issue unsecured commercial paper up to a maximum aggregate amount outstanding at any time of $1,500.0. Borrowings under the program are supported by the Credit Agreement described above. Proceeds of the commercial paper are used for working capital and general corporate purposes, including the repayment of maturing indebtedness and other short-term liquidity needs. The maturities of the commercial paper vary but may not exceed 397 days from the date of issue. During the third quarter of 2023, there was no commercial paper activity, and as of September 30, 2023, there was no commercial paper outstanding.

Cash Pooling

We aggregate our domestic cash position on a daily basis. Outside the United States, we use cash pooling arrangements with banks to help manage our liquidity requirements. In these pooling arrangements, several IPG agencies agree with a single bank that the cash balances of any of the agencies with the bank will be subject to a full right of set-off against amounts other agencies owe the bank, and the bank provides for overdrafts as long as the net balance for all agencies does not exceed an agreed-upon level. Typically, each agency pays interest on outstanding overdrafts and receives interest on cash balances. Our unaudited Consolidated Balance Sheets reflect cash, net of bank overdrafts, under all of our pooling arrangements, and as of September 30, 2023, the amount netted was $2,684.4.

DEBT CREDIT RATINGS

Our debt credit ratings as of October 18, 2023, are listed below.

	Moody’s Investors Service	S&P Global Ratings	Fitch Ratings
Short-term rating	P-2	A-2	F2
Long-term rating	Baa2	BBB	BBB+
Outlook	Stable	Stable	Stable

A credit rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning credit rating agency. The rating of each credit rating agency should be evaluated independently of any other rating. Credit ratings could have an impact on liquidity, either adverse or favorable, because, among other things, they could affect funding costs in the capital markets or otherwise. For example, our Credit Agreement fees and borrowing rates are based on a credit ratings grid, and our access to the commercial paper market is contingent on our maintenance of sufficient short-term debt ratings.

CRITICAL ACCOUNTING ESTIMATES

Our significant accounting policies are described in Note 1 to the Consolidated Financial Statements for the year ended December 31, 2022, included in our 2022 Annual Report. As summarized in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, in our 2022 Annual Report, we believe that certain of these policies are critical because they are important to the presentation of our financial condition and results of operations, and they require management’s most difficult, subjective or complex judgments, often as a result of the need to estimate the effect of matters that are inherently uncertain. These critical estimates relate to revenue recognition, income taxes, goodwill and other intangible assets, and pension and postretirement benefits. We base our estimates on historical experience and various other factors that we believe to be relevant under the circumstances. Estimation methodologies are applied consistently from year to year, and there have been no significant changes in the application of critical accounting estimates since December 31, 2022. Actual results may differ from these estimates under different assumptions or conditions and further decline in macroeconomic conditions or increasing interest rates could have a negative impact on these estimates, including the fair value of certain assets.

RECENT ACCOUNTING STANDARDS

See Note 13 to the unaudited Consolidated Financial Statements for further information on certain accounting standards that have been recently adopted or that have not yet been required to be implemented and may be applicable to our future operations.

NON-GAAP FINANCIAL MEASURE

This MD&A includes both financial measures in accordance with U.S. GAAP, as well as a non-GAAP financial measure. The non-GAAP financial measure represents Net Income Available to IPG Common Stockholders before Provision for Income Taxes, Total (Expenses) and Other Income, Equity in Net (Loss) Income of Unconsolidated Affiliates, Net Income Attributable to Non-controlling Interests and Amortization of Acquired Intangibles, which we refer to as “Adjusted EBITA”.

Adjusted EBITA should be viewed as supplemental to, and not as an alternative for, Net Income Available to IPG Common Stockholders calculated in accordance with U.S. GAAP (“net income”) or operating income calculated in accordance with U.S. GAAP (“operating income”). This section also includes reconciliation of this non-GAAP financial measure to the most directly comparable U.S. GAAP financial measures, as presented below.

Adjusted EBITA is used by our management as an additional measure of our Company’s performance for purposes of business decision-making, including developing budgets, managing expenditures and evaluating potential acquisitions or divestitures. Period-to-period comparisons of Adjusted EBITA help our management identify additional trends in our Company’s financial results that may not be shown solely by period-to-period comparisons of net income or operating income. In addition, we use Adjusted EBITA in the incentive compensation programs applicable to some of our employees in order to evaluate our Company’s performance. Our management recognizes that Adjusted EBITA has inherent limitations because of the excluded items, particularly those items that are recurring in nature. Management also reviews operating income and net income as well as the specific items that are excluded from Adjusted EBITA, but included in net income or operating income, as well as trends in those items. The amounts of those items are set forth, for the applicable periods, in the reconciliation of Adjusted EBITA to net income that accompany our disclosure documents containing non-GAAP financial measures, including the reconciliations contained in this MD&A.

We believe that the presentation of Adjusted EBITA is useful to investors in their analysis of our results for reasons similar to the reasons why our management finds it useful and because it helps facilitate investor understanding of decisions made by management in light of the performance metrics used in making those decisions. In addition, as more fully described below, we believe that providing Adjusted EBITA, together with a reconciliation of this non-GAAP financial measure to net income, helps investors make comparisons between our Company and other companies that may have different capital structures, different effective income tax rates and tax attributes, different capitalized asset values and/or different forms of employee compensation. However, Adjusted EBITA is intended to provide a supplemental way of comparing our Company with other public companies and is not intended as a substitute for comparisons based on net income or operating income. In making any comparisons to other companies, investors need to be aware that companies may use different non-GAAP measures to evaluate their financial performance. Investors should pay close attention to the specific definition being used and to the reconciliation between such measures and the corresponding U.S. GAAP measures provided by each company under the applicable rules of the SEC.

The following is an explanation of the items excluded by us from Adjusted EBITA but included in net income:

•Total (Expenses) and Other Income, Provision for Income Taxes, Equity in Net (Loss) Income of Unconsolidated Affiliates and Net Income Attributable to Non-controlling Interests. We exclude these items (i) because these items are not directly attributable to the performance of our business operations and, accordingly, their exclusion assists management and investors in making period-to-period comparisons of operating performance and (ii) to assist management and investors in making comparisons to companies with different capital structures. Investors should note that these items will recur in future periods.

•Amortization of Acquired Intangibles. Amortization of acquired intangibles is a non-cash expense relating to intangible assets arising from acquisitions that are expensed on a straight-line basis over the estimated useful life of the related assets. We exclude amortization of acquired intangibles because we believe that (i) the amount of such expenses in any specific period may not directly correlate to the underlying performance of our business operations and (ii) such expenses can vary significantly between periods as a result of new acquisitions and full amortization of previously acquired intangible assets. Accordingly, we believe that this exclusion assists management and investors in making period-to-period comparisons of operating performance. Investors should note that the use of intangible assets contributed to revenue in the periods presented and will contribute to future revenue generation and should also note that such expense may recur in future periods.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

In the normal course of business, we are exposed to market risks related to interest rates, foreign currency rates and certain balance sheet items. From time to time, we use derivative instruments, pursuant to established guidelines and policies, to manage some portion of these risks. Derivative instruments utilized in our hedging activities are viewed as risk management tools and are not used for trading or speculative purposes. There has been no significant change in our exposure to market risk during the third quarter of 2023. Our exposure to market risk for changes in interest rates primarily relates to the fair market value and cash flows of our debt obligations. As of September 30, 2023 and December 31, 2022, approximately 99% and 98%, respectively, of our debt obligations bore fixed interest rates. For further discussion of our exposure to market risk, refer to Item 7A, Quantitative and Qualitative Disclosures About Market Risk, in our 2022 Annual Report.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2023, the Company’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Changes in Internal Control Over Financial Reporting

There has been no change in internal control over financial reporting in the quarter ended September 30, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

Information about our legal proceedings is set forth in Note 12 to the unaudited Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Item 1A, Risk Factors, in our 2022 Annual Report on Form 10-K (the “2022 Annual Report”), which could materially affect our business, financial condition or future results. In the third quarter of 2023, there have been no material changes in the risk factors we have previously disclosed in Item 1A, Risk Factors, in our 2022 Annual Report. The risks described in our 2022 Annual Report are not the only risks we face, and additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect the Company’s business, financial condition or operating results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(c)The following table provides information regarding our purchases of our equity securities during the period from July 1, 2023 to September 30, 2023:

	Total Number of Shares (or Units) Purchased 1	Average Price Paid per Share (or Unit) 2		Total Number of Shares (or Units) Purchased as Part of Publicly Announced Plans or Programs 3	Maximum Number (or Approximate Dollar Value) of Shares (or Units) that May Yet Be Purchased Under the Plans or Programs 3
July 1 - 31	652,824	$	38.41	650,540	$	277,151,594
August 1 - 31	1,815,899	$	33.58	1,815,899	$	216,173,502
September 1 - 30	161,701	$	31.59	157,503	$	211,185,785
Total	2,630,424	$	34.66	2,623,942

1The total number of shares of our common stock purchased includes shares withheld under the terms of grants under employee stock-based compensation plans to offset tax withholding obligations that arose upon vesting and release of restricted shares (the “Withheld Shares”). We repurchased 2,284 Withheld Shares in July 2023; no Withheld Shares in August 2023; and 4,198 Withheld Shares in September 2023, for a total of 6,482 Withheld Shares during the three-month period.

2The average price per share for each of the months in the fiscal quarter and for the three-month period was calculated by dividing (a) the sum for the applicable period of the aggregate value of the tax withholding obligations and the aggregate amount we paid for shares acquired under our share repurchase program, described in Note 5 to the unaudited Consolidated Financial Statements, by (b) the sum of the number of Withheld Shares and the number of shares acquired in our share repurchase program.

3On February 8, 2023, the Board authorized a share repurchase program to repurchase from time to time up to $350.0 million, excluding fees, of our common stock. There is no expiration date associated with this share repurchase program.

Item 3. Defaults Upon Senior Securities

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited Consolidated Financial Statements have been prepared by The Interpublic Group of Companies, Inc. and its subsidiaries (the “Company,” “IPG,” “we,” “us” or “our”) in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting interim financial information on Form 10-Q. Accordingly, they do not include certain information and disclosures required for complete financial statements. The effects of heightened macroeconomic uncertainty have impacted and may continue to impact our results of operations, cash flows and financial position. The Company’s Consolidated Financial Statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts of assets and liabilities and related disclosures as of the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company believes it has used reasonable estimates and assumptions to assess the fair values of goodwill, long-lived assets and indefinite-lived intangible assets; assessment of the annual effective tax rate; valuation of deferred income taxes and allowance for expected credit losses on future uncollectible accounts receivable.

Actual results may differ from these estimates under different assumptions or conditions and further decline in macroeconomic conditions or increasing interest rates could have a negative impact on these estimates, including the fair value of certain assets. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”).

We conduct our business across three reportable segments described in Note 10. The three reportable segments are: Media, Data & Engagement Solutions ("MD&E"), Integrated Advertising & Creativity Led Solutions ("IA&C"), and Specialized Communications & Experiential Solutions ("SC&E").

Cost of services is comprised of the expenses of our revenue-producing reportable segments, MD&E, IA&C, and SC&E, including salaries and related expenses, office and other direct expenses and billable expenses, and includes an allocation of the centrally managed expenses from our "Corporate and Other" group. Office and other direct expenses include rent expense, professional fees, certain expenses incurred by our staff in servicing our clients and other costs directly attributable to client engagements.

Selling, general and administrative expenses are primarily the unallocated expenses from Corporate and Other, excluding depreciation and amortization.

Depreciation and amortization of fixed assets and intangible assets of the Company is disclosed as a separate operating expense.

Restructuring charges in 2023 consist of adjustments to the Company's restructuring actions taken in 2022 and 2020, and primarily relate to real estate actions which were designed to reduce our real estate footprint and to better align our cost structure with revenue, as discussed further in Note 5.

In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments, consisting only of normal and recurring adjustments necessary for a fair statement of the information for each period contained therein. Certain reclassifications and immaterial adjustments have been made to prior-period financial statements to conform to the current-period presentation, including the recast of certain prior period amounts to reflect the transfer of certain agencies between reportable segments.

Disaggregation of Revenue

We have three reportable segments as of September 30, 2023: MD&E, IA&C and SC&E, as further discussed in Note 10. MD&E principally generates revenue from providing global media and communications services, digital services and products, advertising and marketing technology, e‐commerce services, data management and analytics, strategic consulting, and digital brand experience. IA&C principally generates revenue from providing advertising, corporate and brand identity services, and strategic consulting. SC&E generates revenue from providing best-in-class global public relations and communications services, events, sports and entertainment marketing, and strategic consulting.

Contract Balances

The following table provides information about receivables, contract assets and contract liabilities from contracts with customers.

	September 30, 2023		December 31, 2022
Accounts receivable, net of allowance of $46.8 and $48.6, respectively	$	4,046.9	$	5,316.0
Accounts receivable, billable to clients	2,417.4		2,023.0
Contract assets	55.7		67.4
Contract liabilities (deferred revenue)	688.4		680.0

Contract assets are primarily comprised of contract incentives that are generally satisfied annually under the terms of our contracts and are transferred to accounts receivable when the right to payment becomes unconditional. Contract liabilities relate

to advance consideration received from customers under the terms of our contracts primarily related to reimbursements of third-party expenses, whether we act as principal or agent, and to a lesser extent, periodic retainer fees, both of which are generally recognized shortly after billing.

The majority of our contracts are for periods of one year or less with the exception of our data management contracts. For those contracts with a term of more than one year, we had approximately $780.4 of unsatisfied performance obligations as of September 30, 2023, which will be recognized as services are performed over the remaining contractual terms through 2028.

Debt Transactions

5.375% Senior Notes due 2033

On June 8, 2023, we issued a total of $300.0 in aggregate principal amount of 5.375% unsecured senior notes (the "5.375% Senior Notes") due June 15, 2033. Upon issuance, the 5.375% Senior Notes were reflected in our unaudited Consolidated Balance Sheets at $292.9, net of discount of $3.8 and net of capitalized debt issuance costs, including commissions and offering expenses of $3.3, both of which will be amortized in interest expense through the maturity date using the effective interest method. Interest is payable semi-annually in arrears on June 15th and December 15th of each year, commencing on December 15, 2023.

Credit Agreement

We maintain a committed corporate credit facility, originally dated as of July 18, 2008, which has been amended and restated from time to time (the "Credit Agreement"). We use our Credit Agreement to increase our financial flexibility, to provide letters of credit primarily to support obligations of our subsidiaries and to support our commercial paper program. On November 1, 2021, we amended and restated the Credit Agreement. As amended, among other things, the maturity date of the Credit Agreement was extended to November 1, 2026 and the cost structure of the Credit Agreement was changed. The Credit Agreement continues to include a required leverage ratio of not more than 3.50 to 1.00, among other customary covenants, including limitations on our liens and the liens of our consolidated subsidiaries and limitations on the incurrence of subsidiary debt. At the election of the Company, the leverage ratio may be changed to not more than 4.00 to 1.00 for four consecutive quarters, beginning with the fiscal quarter in which there is an occurrence of one or more acquisitions with an aggregate purchase price of at least $200.0.

The Credit Agreement is a revolving facility, under which amounts borrowed by us or any of our subsidiaries designated under the Credit Agreement may be repaid and reborrowed, subject to an aggregate lending limit of $1,500.0, or the equivalent in other currencies. The Company has the ability to increase the commitments under the Credit Agreement from time to time by an additional amount of up to $250.0, provided the Company receives commitments for such increases and satisfies certain other conditions. The aggregate available amount of letters of credit outstanding may decrease or increase, subject to a sublimit of $50.0, or the equivalent in other currencies. Our obligations under the Credit Agreement are unsecured. As of September 30, 2023, there were no borrowings under the Credit Agreement; however, we had $9.6 of letters of credit under the Credit Agreement, which reduced our total availability to $1,490.4. We were in compliance with all of our covenants in the Credit Agreement as of September 30, 2023.

Uncommitted Lines of Credit

We also have uncommitted lines of credit with various banks that permit borrowings at variable interest rates and that are primarily used to fund working capital needs. We have guaranteed the repayment of some of these borrowings made by certain subsidiaries. If we lose access to these credit lines, we would have to provide funding directly to some of our operations. As of September 30, 2023, the Company had uncommitted lines of credit in an aggregate amount of $869.9, under which we had outstanding borrowings of $31.0 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the third quarter of 2023 was $47.9 with a weighted-average interest rate of approximately 9.5%.

Commercial Paper

The Company is authorized to issue unsecured commercial paper up to a maximum aggregate amount outstanding at any time of $1,500.0. Borrowings under the program are supported by the Credit Agreement described above. Proceeds of the commercial paper are used for working capital and general corporate purposes, including the repayment of maturing indebtedness and other short-term liquidity needs. The maturities of the commercial paper vary but may not exceed 397 days from the date of issue. During the third quarter of 2023, there was no commercial paper activity and, as of September 30, 2023, there was no commercial paper outstanding.

Net (losses)/gains on sales of businesses – During the three and nine months ended September 30, 2023 and 2022, the amounts recognized were related to sales of businesses and the classification of certain assets and liabilities, consisting primarily of accounts receivable and accounts payable, as held for sale within our MD&E, IA&C, and SC&E reportable segments. The businesses sold and held for sale primarily represent unprofitable, non-strategic agencies which are expected to be sold within the next twelve months.

Other – During the three and nine months ended September 30, 2023, the amounts recognized were primarily related to pension and postretirement costs. During the three months ended September 30, 2022, the amounts recognized were primarily related to a cash gain from the sale of an equity investment. During the nine months ended September 30, 2022, the amounts recognized were primarily attributable to factors noted for the third quarter of 2022, partially offset by a non-cash loss related to the deconsolidation of a previously consolidated entity in which we maintain an equity interest in the second quarter of 2022.

Redeemable Noncontrolling Interest [Table Text Block]

Redeemable Non-controlling Interests

Many of our acquisitions include provisions under which the non-controlling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable non-controlling interests are adjusted quarterly, if necessary, to their estimated redemption value, but not less than their initial fair value. Any adjustments to the redemption value impact retained earnings or additional paid in capital, except for foreign currency translation adjustments.

Goodwill Disclosure

Goodwill is the excess purchase price remaining from an acquisition after an allocation of purchase price has been made to identifiable assets acquired and liabilities assumed based on estimated fair values.

The Company transferred certain agencies between operating segments as of January 1, 2023 which resulted in certain changes to our reporting units and reportable segments. We have allocated goodwill to our reporting units using a relative fair value approach. In addition, we completed an assessment of any potential goodwill impairment for all impacted reporting units immediately prior and subsequent to the reallocation and determined that no impairment existed.

The following table sets forth details of changes in goodwill by reportable segment of the Company:

Income Taxes

Income Taxes

For the three months ended September 30, 2023, our income tax expense was negatively impacted by tax expense associated with the change to our assertion regarding the permanent reinvestment of undistributed earnings attributable to certain foreign subsidiaries. For the nine months ended September 30, 2023, our income tax expense was positively impacted by a benefit of $64.2 related to the settlement of the 2017 and 2018 U.S. Federal income tax audit and excess tax benefits on employee share-based payments, the majority of which were recognized in the first quarter due to the timing of the vesting of awards.

We have various tax years under examination by tax authorities in various countries, and in various states, in which we have significant business operations. It is not yet known whether these examinations will, in the aggregate, result in our paying additional taxes. We believe our tax reserves are adequate in relation to the potential for additional assessments in each of the jurisdictions in which we are subject to taxation. We regularly assess the likelihood of additional tax assessments in those jurisdictions and, if necessary, adjust our reserves as additional information or events require.

With respect to all tax years open to examination by U.S. federal, various state and local, and non-U.S. tax authorities, we currently anticipate that total unrecognized tax benefits will decrease by an amount between $25.0 and $35.0 in the next twelve months, a portion of which will affect our effective income tax rate, primarily as a result of the settlement of tax examinations and the lapsing of statutes of limitations.

We are effectively settled with respect to U.S. federal income tax audits through 2018. With limited exceptions, we are no longer subject to state and local income tax audits for years prior to 2015 or non-U.S. income tax audits for years prior to 2010.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]

Employee Benefits

Employee Benefits

We have a defined benefit pension plan that covers certain U.S. employees (the “Domestic Pension Plan”). We also have numerous funded and unfunded plans outside the U.S. The Interpublic Limited Pension Plan in the U.K. is a defined benefit plan and is our most material foreign pension plan in terms of the benefit obligation and plan assets. Some of our domestic and foreign subsidiaries provide postretirement health benefits and life insurance to eligible employees and, in certain cases, their dependents. The domestic postretirement benefit plan is our most material postretirement benefit plan in terms of the benefit obligation. Certain immaterial foreign pension and postretirement benefit plans have been excluded from the table below.

The components of net periodic cost for the Domestic Pension Plan, the significant foreign pension plans and the domestic postretirement benefit plan are listed below.

Fair Value Measurements (Notes)

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Authoritative guidance for fair value measurements establishes a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial Instruments that are Measured at Fair Value on a Recurring Basis

We primarily apply the market approach to determine the fair value of financial instruments that are measured at fair value on a recurring basis. There were no changes to our valuation techniques used to determine the fair value of financial instruments during the nine months ended September 30, 2023. The following tables present information about our financial instruments measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value.

Assets
Cash equivalents	$	581.3	$	—	$	—	$	581.3	Cash and cash equivalents

Liabilities
Contingent acquisition obligations 1	$	—	$	—	$	21.6	$	21.6	Accrued liabilities and Other non-current liabilities

1Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional non-controlling equity shares of consolidated subsidiaries. Fair value measurement of the obligations is based upon actual and projected operating performance targets as specified in the related agreements. The decrease in this balance of $19.2 from December 31, 2022 to September 30, 2023 is primarily due to payments related to our deferred acquisitions payments from prior-year acquisitions and valuation adjustments, partially offset by new acquisitions and the exercises of redeemable non-controlling interest. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities.

Financial Instruments that are not Measured at Fair Value on a Recurring Basis

The following table presents information about our financial instruments that are not measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

	September 30, 2023								December 31, 2022

Our marketable securities are comprised of U.S. Treasury Securities with maturity dates of less than 1 year and are classified as held-to-maturity. Held-to-maturity investments are stated at amortized cost. The fair value of our marketable securities are measured based on quoted prices in active markets and are classified as Level 1.

Our long-term debt is comprised of senior notes and other notes payable. The fair value of our senior notes, which are traded over-the-counter, is based on quoted prices in markets that are not active. Therefore, these senior notes are classified as Level 2. Our other notes payable are not actively traded, and their fair value is not solely derived from readily observable inputs. The fair value of our other notes payable is determined based on a discounted cash flow model and other proprietary valuation methods, and therefore is classified as Level 3. See Note 3 for further information on our long-term debt.

The discount rates used as significant unobservable inputs in the Level 3 fair value measurements of our contingent acquisition obligations and long-term debt as of September 30, 2023 ranged from 3.0% to 6.0%.

Non-financial Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis, primarily goodwill (Level 3), intangible assets, and property and equipment. Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment.

Commitments and Contingencies

Guarantees

As discussed in our 2022 Annual Report, we have guaranteed certain obligations of our subsidiaries relating principally to operating leases and uncommitted lines of credit of certain subsidiaries. As of September 30, 2023 and December 31, 2022, the amount of parent company guarantees on lease obligations was $725.0 and $797.3, respectively, the amount of parent company guarantees primarily relating to uncommitted lines of credit was $276.3 and $276.4, respectively, and the amount of parent company guarantees related to daylight overdrafts, primarily utilized to manage intra-day overdrafts due to timing of transactions under cash pooling arrangements without resulting in incremental borrowings, was $106.8 and $101.3, respectively. In the event of non-payment by the applicable subsidiary of the obligations covered by a guarantee, we would be obligated to pay the amounts covered by that guarantee. As of both September 30, 2023, and December 31, 2022 there were no material assets pledged as security for such parent company guarantees.

Legal Matters

We are involved in various legal proceedings, and subject to investigations, inspections, audits, inquiries and similar actions by governmental authorities arising in the normal course of business. The types of allegations that arise in connection with such legal proceedings vary in nature, but can include claims related to contract, employment, tax and intellectual property matters. We evaluate all cases each reporting period and record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount, or potential range, of loss can be reasonably estimated. In certain cases, we cannot reasonably estimate the potential loss because, for example, the litigation is in its early stages. While any outcome related to litigation or such governmental proceedings in which we are involved cannot be predicted with certainty, management believes that the outcome of these matters, individually and in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows.

Recent Accounting Standards

Accounting pronouncements not listed below were assessed and determined to be not applicable or are expected to have minimal impact on our Consolidated Financial Statements.

Derivatives and Hedging

In March 2022, the Financial Accounting Standards Board (the "FASB") issued amended guidance on hedge accounting which allows nonprepayable financial assets to be included in a closed portfolio hedge using the portfolio layer method, allowing for more consistent accounting over prepayable and nonprepayable hedges. The new guidance also allows multiple hedged layers to be designated for a single closed portfolio, further aligning hedge accounting with risk management strategies. We adopted the standard January 1, 2023, which did not have a significant impact on our financial statements.

Net (losses)/gains on sales of businesses – During the three and nine months ended September 30, 2023 and 2022, the amounts recognized were related to sales of businesses and the classification of certain assets and liabilities, consisting primarily of accounts receivable and accounts payable, as held for sale within our MD&E, IA&C, and SC&E reportable segments. The businesses sold and held for sale primarily represent unprofitable, non-strategic agencies which are expected to be sold within the next twelve months.

Other – During the three and nine months ended September 30, 2023, the amounts recognized were primarily related to pension and postretirement costs. During the three months ended September 30, 2022, the amounts recognized were primarily related to a cash gain from the sale of an equity investment. During the nine months ended September 30, 2022, the amounts recognized were primarily attributable to factors noted for the third quarter of 2022, partially offset by a non-cash loss related to the deconsolidation of a previously consolidated entity in which we maintain an equity interest in the second quarter of 2022.

Redeemable Noncontrolling Interest [Table Text Block]

Redeemable Non-controlling Interests

Many of our acquisitions include provisions under which the non-controlling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable non-controlling interests are adjusted quarterly, if necessary, to their estimated redemption value, but not less than their initial fair value. Any adjustments to the redemption value impact retained earnings or additional paid in capital, except for foreign currency translation adjustments.

The following table presents changes in our redeemable non-controlling interests.

Fair value measurement of the obligations is based upon actual and projected operating performance targets as specified in the related agreements. The decrease in this balance of $19.2 from December 31, 2022 to September 30, 2023 is primarily due to payments related to our deferred acquisitions payments from prior-year acquisitions and valuation adjustments, partially offset by new acquisitions and the exercises of redeemable non-controlling interest. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities.

[1] Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional non-controlling equity shares of consolidated subsidiaries. Fair value measurement of the obligations is based upon actual and projected operating performance targets as specified in the related agreements. The decrease in this balance of $19.2 from December 31, 2022 to September 30, 2023 is primarily due to payments related to our deferred acquisitions payments from prior-year acquisitions and valuation adjustments, partially offset by new acquisitions and the exercises of redeemable non-controlling interest. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities.
