To learn more about our broad range of capabilities, visit our website at www.interpublic.com. Information on our website is not part of this report.

We operate in a media landscape 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 strategictechnology talent in areas including 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 intra-company 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.

In recent years, we have taken several major strategic steps to position our agencies as leaders in the global advertising and communications market. These include:

Our large and diverse client base includes many of the most recognizable companies and brands throughout the world. Our holding company structure allows us to maintain a diversified client base across and within a full range of industry sectors. In the aggregate, our top ten clients based on net revenue accounted for approximately 20%17% of net revenue in both 20172019 and 2016.18% in 2018. Our largest client accounted for approximately 3% of net revenue in 2019 and 4% of net revenue for both 2017 and 2016.in 2018. Based on net revenue for the year ended December 31, 2017,2019, our largest client sectors (in alphabetical order) were auto and transportation, healthcare and technology and telecom. We represent several different clients, brands or divisions within each of these sectors in a number of geographic markets, as well as provide services across multiple advertising and marketing disciplines, in each case through more than one of our agency brands. Representation of a client rarely means that we handle advertising for all brands or product lines of the client in all geographical locations. Any client may transfer its business from one of our agencies to another one of our agencies or to a competing agency, and a client may reducechange its marketing budget at any time.

We operate in a highly competitive advertising and marketing communications industry. Our operating companies compete against other large multinational advertising and marketing communications companies as well as numerous independent and niche agencies and new forms of market participants to win new clients and maintain existing client relationships.

The advertising and marketing services that our agencies provide are subject to governmental regulation and other action in all of the jurisdictions in which the Company operates. While these governmental regulations and other actions can impact the Company’s operations, the specific marketing regulations we may face in a given market do not as a general matter significantly impact the Company’s overall service offerings or the nature in which we provide these services.

Governments, government agencies and industry self-regulatory bodies have adopted laws, regulations and standards, and judicial bodies have issued rulings, that directly or indirectly affect the form and content of advertising, public relations and other marketing activities we produce or conduct on behalf of our clients. These laws, regulations and other actions include content-related rules with respect to specific products and services, restrictions on media scheduling and placement, and labeling or warning requirements with respect to certain products, for example pharmaceuticals, alcoholic beverages, cigarettes and other tobacco products, and food and nutritional supplements. We are also subject to rules related to marketing directed to certain groups, such as children.

Digital marketing services are a dynamic and growing sector of our business. Our service offerings in this area are covered by laws and regulations concerning user privacy, use of personal information, data protection and online tracking technologies. ExistingWe are also subject to laws and regulations that govern whether and how we can transfer, process or receive certain data that we use in our operations, including data shared between countries or regions in which we operate. While we maintain policies and operational procedures to promote effective privacy protection and data management, existing and proposed laws and regulations in this area, such as the General Data Protection Regulation ("GDPR"(“GDPR”) coming into effect in the European Union, the California Consumer Privacy Act (“CCPA”) that recently went into effect and other different forms of privacy legislation under consideration across the markets in which we operate, can impact the development, efficacy and profitability of internet-based and other digital marketing. Limitations on the scheduling, content or delivery of direct marketing activities can likewise impact the activities of our agencies offering those services.

With agencies and clients located in over 100 countries worldwide, we are also subject to laws governing our international operations. These include broad anti-corruption laws such as the U.S. Foreign Corrupt Practices Act ("FCPA") and the U.K. Bribery Act (2010), which generally prohibit the making or offering of improper payments to government officials and political figures. Export controls and economic sanctions regimes, such as those maintained by the U.S. government and comparable ones by the U.K., the member states of the European Union and the U.N., impose limitations on the Company’s ability to operate in certain geographic regions or to

As of December 31, 2017,2019, we employed approximately 50,20054,300 people, of whom approximately 20,10022,400 were employed in the United States. Because of the service character of the advertising and marketing communications business, the quality of personnel is of crucial importance to our continuing success. We conduct extensive employee training and development throughout our agencies and benchmark our compensation programs against those of our industry for their competitiveness and effectiveness in recruitment and retention. There is keen competition for qualified employees.

The advertising and marketing communications business is highly competitive.competitive and constantly changing. Our agencies and media services compete with other agencies and other providers of creative, marketing or media services to maintain existing client relationships and to win new business. Our competitors include not only other large multinational advertising and marketing communications companies, but also smaller entities that operate in local or regional markets as well as new forms of market participants.

Competitive challenges also arise from rapidly-evolving and new technologies in the marketing and advertising space, creating opportunities for new and existing competitors and a need for continued significant investment in tools, technologies and process improvements. As data-driven marketing solutions become increasingly core to the success of our brands, any failure to keep up with rapidly changing technologies and standards in this space could harm our competitive position.

The client’s perception of the quality of our agencies’ creative work, its confidence in our ability to protect the confidentiality of their and their customers’ data and its relationships with key personnel at the Company or our agencies are important factors that affect our competitive position. An agency’s ability to serve clients, particularly large international clients, on a broad geographic basis and across a range of services and technologies may also be an important competitive consideration. On the other hand, because an agency’s principal asset is its people and freedom of entry into the industry is almost unlimited, our relationships with clients can be affected by the departure of key personnel and a small agency is, on occasion, able to take all or some portion of a client’s account from a much larger competitor.

Many companies put their advertising and marketing communications business up for competitive review from time to time, and we have won and lost client accounts in the past as a result of such periodic competitions. Our clients may choose to terminate their contracts, or reduce their relationships with us, on a relatively short time frame and for any reason. A relatively small number of clients contribute a significant portion of our revenue. In the aggregate, our top ten clients based on revenue accounted for approximately 20%17% of revenue in 2017.2019. A substantial decline in a large client’s advertising and marketing spending, or the loss of a significant part of its business, could have a material adverse effect upon our business and results of operations.

Our ability to attract new clients and to retain existing clients may also, in some cases, be limited by clients’ policies or perceptions about conflicts of interest, or our own exclusivity arrangements with certain clients. These policies can, in some cases, prevent one agency, or even different agencies under our ownership, from performing similar services for competing products or companies.

We are exposed to risks associated with weak or uncertain regional or global economic conditions and increased disruption in the financial markets. The global economy continues to be challenging in some parts of the world.markets. Uncertainty about the continued strength of the global economy generally, or economic conditions in certain regions or market sectors, and a degree of caution on the part of some marketers, continue tocan have an effect on the demand for advertising and marketing communication services. In addition, market conditions can be adversely affected by natural and human disruptions, such as natural disasters, severe weather events, military conflict or public health crises. Our industry can be affected more severely than other sectors by an economic downturn and can recover more slowly than the economy in general. In the past, some clients have responded to weak economic and financial conditions by reducing their marketing budgets, which include discretionary components that are easier to reduce in the short term than other operating expenses. This pattern may recur in the future. Furthermore, unexpected revenue shortfalls can result in misalignments of costs and revenues, resulting in a negative impact to our operating margins. If our business is significantly adversely affected by unfavorable economic conditions or other market disruptions that adversely affect client spending, the negative impact on our revenue could pose a challenge to our operating income and cash generation from operations.

Our employees, including creative, digital, research, media and account specialists, and their skills and relationships with clients, are among our most valuable assets. An important aspect of our competitiveness is our ability to identify and develop the appropriate talent and to attract and retain key employees and management personnel. Our ability to do so is influenced by a variety of factors, including the compensation we award and other factors which may be beyond our control. Changes to U.S. or other immigration policies or travel restrictions imposed as a result of public health, political or security concerns, that restrain the flow of professional talent may inhibit our ability to staff our offices or projects. In addition, the advertising and marketing services industry is characterized by a high degree of employee mobility.mobility and significant use of third-party or temporary workers to staff new, growing or temporary assignments. If we were to fail to attract key personnel or lose them to competitors or clients, or fail to manage our workforce effectively, our business and results of operations could be adversely affected.

We have a large and diverse client base, and at any given time, one or more of our clients may experience financial difficulty, file for bankruptcy protection or go out of business. Unfavorable economic and financial conditions could result in an increase in client financial difficulties that affect us. The direct impact on us could include reduced revenues and write-offs of accounts receivable and expenditures billable to clients, and if these effects were severe, the indirect impact could include impairments of intangible assets, credit facility covenant violations and reduced liquidity.

Furthermore, in most of our businesses, our agencies enter into commitments to pay production and media costs on behalf of clients. The amounts involved substantially exceed our revenues and primarily affect the level of accounts receivable, expenditures billable to clients, accounts payable and accrued liabilities. To the extent possible, we pay production and media charges only after we have received funds from our clients. However, if clients are unable to pay for commitments that we have entered into on their behalf, or if clients seek to significantly delay or otherwise alter payment terms, there could be an adverse effect on our working capital, which would negatively impact our operating cash flow.

We are a global business, with agencies located in over 100 countries, including every significant world market. Operations outside the United States represent a significant portion of our net revenues, approximately 40%38% in 2017.2019. These operations are exposed to risks that include local legislation, currency variation, exchange control restrictions, local labor and employment laws that hinder workforce flexibility, large-scale local or regional public health crises, and other difficult social, political or economic conditions. We also must comply with applicable U.S., local and other international anti-corruption laws, including the FCPA and the U.K. Anti-Bribery Act (2010), which can be comprehensive, complex and stringent, in all jurisdictions where we operate.operate, certain of which present heightened compliance challenges. Export controls and economic sanctions, such as those maintained by the Office of Foreign Assets Control of the U.S. Department of the Treasury, can impose limitations on our ability to operate in certain geographic regions or to seek or service certain potential clients. These restrictions can place us at a competitive disadvantage with respect to those competitors who may not be subject to comparable restrictions. Failure to comply or to implement business practices that sufficiently prevent corruption or violation of sanctions laws could result in significant remediation expense and expose us to significant civil and criminal penalties and reputational harm.

Given our substantial operations in the United Kingdom and Continental Europe, we face continued uncertainty surrounding the implementation and effectsconsequences of the U.K.’s June 2016 referendum in which voters approved the United Kingdom’s exit from the European Union, commonly referred to as “Brexit.” ItUnder the withdrawal agreement negotiated between the U.K. and the E.U., the U.K. as of January 31, 2020, is no longer a member of the European Union, and a transitional period will occur through December 31, 2020, during which the parties intend to negotiate the terms of their future economic and trade relationship. During and following this transitional period, it is possible that Brexit and changes resulting from Brexit will cause increased regulatory and legal complexities, large exchange rate fluctuations and create uncertainty surrounding our business, including our relationships with existingnegative economic impacts. These impacts and future clients, suppliers and employees, and the potential impact ofany increased restrictions on the free movement of labor, capital, goods and services between the United Kingdom and the remaining members of the European Union, which could create uncertainty surrounding our business, including our relationships with existing and future clients, suppliers and employees, and have an adverse effect on our business, financial results and operations.

In developing countries or regions, we may face further risks, such as slower receipt of payments, nationalization, social and economic instability, currency repatriation restrictions and undeveloped or inconsistently enforced commercial laws. These risks may limit our ability to grow our business and effectively manage our operations in those countries.

In addition, because a significant portion of our business is denominated in currencies other than the U.S. Dollar, such as the Australian Dollar, Brazilian Real, British Pound Sterling, Canadian Dollar, Chinese Yuan Renminbi, Euro and Indian Rupee, fluctuations in exchange rates between the U.S. Dollar and such currencies, including the persistent strength of the U.S. Dollar in recent periods, may adversely affect our financial results. In particular, Brexit has caused, and may continue to cause, significant volatility in currency exchange rates, especially between the U.S. Dollar and the British Pound Sterling.

Our industry is subject to government regulation and other governmental action, both domestic and foreign. Advertisers and consumer groups may challenge advertising through legislation, regulation, judicial actions or otherwise, for example on the grounds that the advertising is false and deceptive or injurious to public welfare. Our business is also subject to specific rules, prohibitions, media restrictions, labeling disclosures and warning requirements applicable to advertising for certain products. Existing and proposed laws and regulations, in particular in the European Union and the United States, concerning user privacy, use of personal information and on-line tracking technologies could affect the efficacy and profitability of internet-based, digital and digitaltargeted marketing. We are also subject to laws and regulations that govern whether and how we can transfer, process or receive certain data that we use in our operations. The costs of compliance with these laws may increase in the future as a result of the implementation of new laws or regulations, such as the GDPR and the CCPA, or changes in interpretations of current ones.ones, such as the interpretation of existing consumer protection laws as imposing restrictions on the online collection, storage and use of personal data. The imposition of restrictions on certain technologies by private market participants in response to privacy concerns could also have a negative impact on our digital business. If we are unable to transfer data between countries and regions in which we operate, or if we are prohibited from sharing data among our products and services, it could affect the manner in which we provide our services or adversely affect our financial results. Any failure on our part to comply with these legal requirements, or their application in an unanticipated manner, could harm our business and result in penalties or significant legal liability. Legislators, agencies and other governmental units may also continue to initiate proposals to ban the advertising of specific products, such as alcohol, tobacco or tobacco,marijuana products, and to impose taxes on or deny deductions for advertising, which, if successful, may

We regularly undertake acquisitions and other investments that we believe will enhance our service offerings to our clients.clients, such as our acquisition of Acxiom in 2018. These transactions can involve significant challenges and risks, including that the transaction does not advance our business strategy or fails to produce a satisfactory return on our investment. While our evaluation of any potential acquisition includes business, legal and financial due diligence with the goal of identifying and evaluating the material risks involved, we may be unsuccessful in ascertaining or evaluating all such risks. Though we typically structure our acquisitions to provide for future contingent purchase payments that are based on the future performance of the acquired entity, our forecasts of the investment’s future performance also factor into the initial consideration. When actual financial results differ, our returns on the investment could be adversely affected.

We may also experience difficulty integrating new employees, businesses, assets or systems into our organization, including with respect to our internal policies and required controls. We may face reputational and legal risks in situations where we have a significant minority investment but limited control over the investment's operations. Furthermore, it may take longer than anticipated to realize the expected benefits from these transactions, or those benefits may ultimately be smaller than anticipated or may not be realized at all. Talent is among our most valuable assets, and we also may not realize the intended benefits of a transaction if we fail to retain targeted personnel. Acquisition and integration activity may also divert management’s attention and other corporate resources from other business needs. If we fail to realize the intended advantages of any given investment or acquisition, or if we do not identify or correctly measure the associated risks and liabilities, our results of operations and financial position could be adversely affected.

We rely extensively and increasingly on information technologies and infrastructure to manage our business, including digital storage of marketing strategies and client information, developingdevelop new business opportunities and digital products, and processingprocess business transactions. The incidence of malicious technology-related events, such as cyberattacks, computer hacking, computer viruses, worms or other destructive or disruptive software, phishing attacks and other attempts to gain access to confidential or personal data, denial of service attacks or other malicious activities is on the rise worldwide.worldwide and highlights the need for continual and effective cybersecurity awareness and education. Our business, which increasingly involves the collection, use and transmission of customer data, may make us and our agencies attractive targets for malicious third-party attempts to access this data. Power outages, equipment failure, natural disasters (including extreme weather), terrorist activities or human error may also affect our systems and result in disruption of our services or loss or improper disclosure of personal data, business information, including intellectual property, or other confidential information. We operate in many respects on a decentralized basis, with a large number of agencies and legal entities, and the resulting size, diversity and disparity of our technology systems and complications in implementing standardized technologies and procedures could increase our potential vulnerability to such breakdowns, malicious intrusions or attacks.

Likewise, data privacy breaches, as well as improper use of social media, by employees and others may pose a risk that sensitive data, such as personally identifiable information, strategic plans and trade secrets, could be exposed to third parties or to the general public. We operate worldwide, and the legal rules governing data transfers are often complex, conflicting, unclear or ever-changing. We also utilize third parties, including third-party “cloud” computing services, to store, transfer or process data, and system failures or network disruptions or breaches in the systems of such third parties could adversely affect our reputation or business.

Any such breaches or breakdowns could expose us to legal liability, be expensive to remedy, result in a loss of our or our clients’ or vendors’ proprietary information and damage our reputation. Efforts to develop, implement and maintain security measures are costly, may not be successful in preventing these events from occurring and require ongoing monitoring and updating as technologies and cyberattack techniques change frequently, or are not recognized until successful and efforts to overcome security measures become more sophisticated.

We evaluate all of our long-lived assets (including goodwill, other intangible assets and fixed assets), investments and deferred tax assets for possible impairment or realizability annually or whenever there is an indication that they are impaired or not realizable. If certain criteria are met, we are required to record an impairment charge or valuation allowance.

We maintainAgency operating cash flows have a $1.5 billion committed corporate credit facility (the “Credit Agreement”) to increasesignificant impact on our financial flexibility. We alsoliquidity, and we maintain a commercial paper program, under whicha committed corporate credit facility and uncommitted lines of credit to increase flexibility in support of our operating needs. If any of these sources were unavailable or insufficient, our liquidity and ability to adequately fund our operations could be adversely affected. Furthermore, if our business or financial needs lead us to seek new or additional sources of liquidity, including in the capital markets, there can be no guarantee that we would be able to access any new sources of liquidity on commercially reasonable terms or at all.

Under our commercial paper program, we are authorized to issue short-term debt up to an aggregate amount outstanding at any time of $1.5 billion, which we use for working capital and general corporate purposes. Borrowings under the commercial

The Credit Agreement contains financiala leverage ratio and other, non-financial, covenants, and events like a material economic downturn could adversely affect our ability to comply with them. For example, compliance with the financial covenantscovenant would be more difficult to achieve if we were to experience increased indebtedness or substantially lower revenues, including as a result of economic downturns, client losses or a substantial increase in client defaults or sizable asset impairment charges.defaults. If we were unable to comply with any of the financial covenants contained in the Credit Agreement, we could be required to seek an amendment or waiver from our lenders, and our costs under the Credit Agreementthese agreements could increase. If we were unable to obtain a necessary amendment or waiver, the Credit Agreement could be terminated, and any outstanding amounts could be subject to acceleration.acceleration, and we could lose access to certain uncommitted financing arrangements and commercial paper.

Because ratings are an important factor influencing our ability to access capital and the terms of any new indebtedness, including covenants and interest rates, we could be adversely affected if our credit ratings were downgraded or if they were significantly weaker than those of our competitors. Our access to the commercial paper market is contingent on our maintenance of sufficient short-term debt ratings, and any downgrades to those ratings could increase our borrowing costs and reduce the market capacity for, or our ability to issue, commercial paper. Our clients and vendors may also consider our credit profile when negotiating contract terms, and if they were to change the terms on which they deal with us, it could have an adverse effect on our liquidity.

Although asAs a non-manufacturingnon–location–specific, non–manufacturing service business we generallyhave to date been sheltered from or able to mitigate many direct impacts from climate change and related laws and regulations. We are, not directlyhowever, increasingly impacted by currentthe effects of climate change and laws and regulations with respectrelated to climate change and other sustainability concerns, and, we could incur related costs indirectly through our clients. Increasingly our clients request that we comply with their own social responsibility, sustainability or other business policies or standards, which may be more restrictive than current laws and regulations, before they commence, or continue, doing business with us.us, and sustainability and governance issues are increasingly a focus of the investor community. Our compliance with these policies and related certification requirements could be costly, and our failure to comply could adversely affect our business relationships or reputation. If large shareholders were to reduce their ownership stakes in our Company as a result of dissatisfaction with our policies or efforts in this area, there could be negative impact on our stock price, and we could also suffer reputational harm. Further, if clients’ costs are adversely affected by climate change or related laws and regulations, this could negatively impact their spending on our advertising and marketing services. We could also face increased prices from our own suppliers that face climate change-related costs and that seek to pass on their increased costs to their customers.
