NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Presentation of Financial Statements

The terms “Omnicom,” “the Company,” “we,” “our” and “us” each refer to Omnicom Group Inc. and its subsidiaries, unless the context indicates otherwise. The accompanying unaudited consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP or GAAP, for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission, or SEC. Accordingly, certain information and footnote disclosure have been condensed or omitted.

In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation, in all material respects, of the information contained herein. These unaudited consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018, or 2018 10-K. Results for the interim periods are not necessarily indicative of results that may be expected for the year.

Accounting Changes

Except for the changes discussed below, Omnicom has consistently applied the accounting policies to all periods presented in these unaudited consolidated financial statements.

Adoption of ASC 842

On January 1, 2019, we adopted FASB Accounting Standards Codification, or ASC, Topic 842, Leases, or ASC 842, which requires the recognition of the right-of-use assets and related operating and finance lease liabilities on the balance sheet. As permitted by ASC 842, we elected the adoption date of January 1, 2019, which is the date of initial application. As a result, the consolidated balance sheet prior to January 1, 2019 was not restated, continues to be reported under ASC Topic 840, Leases, or ASC 840, which did not require the recognition of operating lease liabilities on the balance sheet, and is not comparative. Under ASC 842, all leases are required to be recorded on the balance sheet and are classified as either operating leases or finance leases. The lease classification affects the expense recognition in the income statement. Operating lease charges are recorded entirely in operating expenses. Finance lease charges are split, where amortization of the right-of-use asset is recorded in operating expenses and an implied interest component is recorded in interest expense. The expense recognition for operating leases and finance leases under ASC 842 is substantially consistent with ASC 840. As a result, there is no significant difference in our results of operations presented in our consolidated income statement and consolidated statement of comprehensive income for each period presented.

We adopted ASC 842 using a modified retrospective approach for all leases existing at January 1, 2019. The adoption of ASC 842 had a substantial impact on our balance sheet. The most significant impact was the recognition of the operating lease right-of-use assets and the liability for operating leases. The accounting for finance leases (capital leases) was substantially unchanged. Accordingly, upon adoption, leases that were classified as operating leases under ASC 840 were classified as operating leases under ASC 842, and we recorded an adjustment of $1,490.1 million to operating lease right-of-use assets and the related lease liability. The lease liability is based on the present value of the remaining minimum lease payments, determined under ASC 840, discounted using our secured incremental borrowing rate at the effective date of January 1, 2019, using the original lease term as the tenor. As permitted under ASC 842, we elected several practical expedients that permit us to not reassess (1) whether a contract is or contains a lease, (2) the classification of existing leases, and (3) whether previously capitalized costs continue to qualify as initial indirect costs. The application of the practical expedients did not have a significant impact on the measurement of the operating lease liability.

The impact of the adoption of ASC 842 on the balance sheet at December 31, 2018 was (in millions):

	As Reported December 31, 2018		Adoption of ASC 842 Increase (Decrease)			Balance January 1, 2019
Other current assets	$	1,241.4	$	(29.2	)	$	1,212.2
Operating lease right-of-use assets	—		1,306.5			1,306.5
Total assets	24,617.0		1,277.3			25,894.3
Other current liabilities	1,958.6		172.5			2,131.1
Long-term liability - Operating leases	—		1,258.5			1,258.5
Long-term liabilities	1,197.8		(153.7		)	1,044.1
Total liabilities and equity	24,617.0		1,277.3			25,894.3

We lease substantially all our office space, technology equipment and office equipment used to conduct our business. We adopted ASC 842 effective January 1, 2019. For contracts entered into on or after the effective date, at the inception of a contract we assess whether the contract is, or contains, a lease. Our assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether we have the right to direct the use of the asset. At inception of a lease, we allocate the consideration in the contract to each lease component based on its relative stand-alone price to determine the lease payments. Leases entered into prior to January 1, 2019, are accounted for under ASC 840 and were not reassessed.

Leases are classified as either finance leases or operating leases. A lease is classified as a finance lease if any one of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it does not meet any one of these criteria. Substantially all our operating leases are comprised of office space leases, and substantially all our finance leases are comprised of office furniture and technology equipment.

For all leases at the lease commencement date, a right-of-use asset and a lease liability are recognized. The right-of-use asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease.

The right-of-use asset is initially measured at cost, which primarily comprises the initial amount of the lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All right-of-use assets are reviewed for impairment. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our secured incremental borrowing rate for the same term as the underlying lease. For our real estate and other operating leases, we use our secured incremental borrowing rate. For our finance leases, we use the rate implicit in the lease or our secured incremental borrowing rate if the implicit lease rate cannot be determined.

Lease payments included in the measurement of the lease liability comprise the following: the fixed noncancelable lease payments, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early.

Some of our real estate leases contain variable lease payments, including payments based on an index or rate. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement and separated into lease and non-lease components based on the initial amount stated in the lease or standalone selling prices. Lease components are included in the measurement of the initial lease liability. Additional payments based on the change in an index or rate, or payments based on a change in our portion of the operating expenses, including real estate taxes and insurance, are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability.

Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage commissions, and is recognized on a straight-line basis over the lease term. Included in lease expense are any variable lease payments incurred in the period that were not included in the initial lease liability. Lease expense for finance leases consists of the amortization of the right-of-use asset on a straight-line basis over the lease term and interest expense determined on an amortized cost basis. The lease payments are allocated between a reduction of the lease liability and interest expense.

We have elected not to recognize right-of-use assets and lease liabilities for short-term leases that have a term of 12 months or less. The effect of short-term leases on our right-of-use asset and lease liability was not material.

Adoption of ASU 2018-02

On January 1, 2019, we adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income: Reclassification of Certain Tax effects from Accumulated Other Comprehensive Income, or ASU 2018-02, which requires the reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects arising from the change in the reduction of the U.S. federal statutory income tax rate to 21% from 35%. The tax effects of items included in accumulated comprehensive income at December 31, 2017 did not reflect the appropriate tax rate. The adoption of ASU 2018-02 resulted in reclassification between accumulated other comprehensive income and retained earnings of $22.3 million, and had no impact on our results of operations or financial position.

Contract assets and liabilities

Work in process includes contract assets, unbilled fees and costs, and media and production costs. Contract liabilities primarily consist of customer advances. At March 31, 2019, December 31, 2018 and March 31, 2018 work in process and contract liabilities were (in millions):

	March 31, 2019		December 31, 2018		March 31, 2018
Work in process:
Contract assets and unbilled fees and costs	$	755.5	$	540.1	$	782.9
Media and production costs	558.9		621.4		595.1
	$	1,314.4	$	1,161.5	$	1,378.0
Contract liabilities:
Customer advances	$	1,104.1	$	1,159.0	$	1,214.3

Work in process consists of accrued costs incurred on behalf of customers, including media and production costs, and fees and other third-party costs that have not yet been billed. Media and production costs are billed during the production process in accordance with the terms of the client contract. Contract assets, which primarily include incentive fees, are not material and will be billed to clients in accordance with the terms of the client contract. Substantially all unbilled fees and costs will be billed within the next 30 days. The contract liability primarily represents advance billings to customers in accordance with the terms of the client contracts, primarily for the reimbursement of third-party costs that are generally incurred in the near term. There were no impairment losses to the contract assets recorded in 2019.

3. New Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. We will adopt ASU 2016-13 on January 1, 2020. However, we are not yet in a position to assess the impact of the new standard on our results of operations or financial position.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other, Internal-Use Software, or ASU 2018-15, which aligns the accounting for implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted at any interim period. ASU 2018-15 may be adopted either on a prospective basis upon early adoption or the effective date for implementation costs for new or existing arrangements incurred on or after the adoption date, or on a full retrospective basis to the earliest period presented. We are not yet in a position to assess the adoption date or the adoption method or to assess impact of the new standard on our results of operations or financial position.

6. Debt

Credit Facilities

At March 31, 2019, our short-term liquidity sources include a $2.5 billion revolving credit facility, or Credit Facility, expiring on July 31, 2021, uncommitted credit lines aggregating $1.5 billion and the ability to issue up to $2 billion of commercial paper.

There were no outstanding commercial paper issuances or borrowings under the Credit Facility or the uncommitted credit lines at March 31, 2019 and December 31, 2018. Available and unused credit lines at March 31, 2019 and December 31, 2018 were (in millions):

	2019		2018
Credit Facility	$	2,500.0	$	2,500.0
Uncommitted credit lines	1,479.3		1,231.6
Available and unused credit lines	$	3,979.3	$	3,731.6

The Credit Facility contains financial covenants that require us to maintain a Leverage Ratio of consolidated indebtedness to consolidated EBITDA of no more than 3 times for the most recently ended 12-month period (EBITDA is defined as earnings before interest, taxes, depreciation and amortization) and an Interest Coverage Ratio of consolidated EBITDA to interest expense of at least 5 times for the most recently ended 12-month period.At March 31, 2019 we were in compliance with these covenants as our Leverage Ratio was 2.3 times and our Interest Coverage Ratio was 9.8 times. The Credit Facility does not limit our ability to declare or pay dividends or repurchase our common stock.

Short-Term Debt

In February 2019, Omnicom Finance Limited, a wholly owned subsidiary of Omnicom, or OFL, issued €520 million of short-term senior notes in a private placement to an investor outside the United States. The notes are unsecured, non-interest bearing and mature on August 14, 2019. The notes are fully and unconditionally guaranteed by Omnicom and rank equal in right of payment with all existing and future unsecured senior indebtedness of OFL. The notes are redeemable in full at OFL's option on June 14, 2019 at a redemption price equal to 100% of the principal amount. Short-term debt at March 31, 2019 and December 31, 2018 was $595.4 million and $8.1 million, respectively. Due to its short-term nature, the carrying value of the short-term debt approximates fair value.

Long-Term Debt

Long-term debt at March 31, 2019 and December 31, 2018 was (in millions):

	2019			2018
6.25% Senior Notes due 2019	$	500.0		$	500.0
4.45% Senior Notes due 2020	1,000.0			1,000.0
3.625% Senior Notes due 2022	1,250.0			1,250.0
3.65% Senior Notes due 2024	750.0			750.0
3.60% Senior Notes due 2026	1,400.0			1,400.0
	4,900.0			4,900.0
Unamortized premium (discount), net	4.6			4.9
Unamortized debt issuance costs	(15.4		)	(16.4		)
Unamortized deferred gain from settlement of interest rate swaps	43.4			48.0
Fair value adjustment attributed to outstanding interest rate swaps	(30.8		)	(52.8		)
	4,901.8			4,883.7
Current portion	(499.8		)	(499.6		)
Long-term debt	$	4,402.0		$	4,384.1

Omnicom and its wholly owned finance subsidiary, Omnicom Capital Inc., or OCI, are co-obligors under all the senior notes. The senior notes are a joint and several liability of us and OCI, and we unconditionally guarantee OCI’s obligations with respect to the senior notes. OCI provides funding for our operations by incurring debt and lending the proceeds to our operating subsidiaries. OCI’s assets primarily consist of cash and cash equivalents and intercompany loans made to our operating subsidiaries, and the related interest receivable. There are no restrictions on the ability of OCI or us to obtain funds from our subsidiaries through dividends, loans or advances. Our senior notes are senior unsecured obligations that rank equal in right of payment with all existing and future unsecured senior indebtedness.

At March 31, 2019, we recorded a long-term liability of $9.8 million in connection with the $750 million fixed-to-floating interest rate swap on our 3.65% Senior Notes due 2024, or 2024 Notes, and a long-term liability of $21.0 million in connection with the $500 million fixed-to-floating interest rate swap on our 3.60% Senior Notes due 2026, or 2026 Notes. The liabilities represent the fair value of the swaps on the 2024 Notes and 2026 Notes that was substantially offset by the change in the fair value of the notes. The fixed-to-floating interest rate swaps have the economic effect of converting our debt portfolio to approximately 75% fixed rate obligations and 25% floating rate obligations.

7. Segment Reporting

Our five branded agency networks operate in the advertising, marketing and corporate communications services industry, and are organized into agency networks, virtual client networks, regional reporting units and operating groups or practice areas. Our networks, virtual client networks and agencies increasingly share clients and provide clients with integrated services. The main economic components of each agency are employee compensation and related costs and direct service costs and occupancy and other costs which include rent and occupancy costs, technology costs and other overhead expenses. Therefore, given these similarities, we aggregate our operating segments, which are our five agency networks, into one reporting segment.

The agency networks' regional reporting units comprise three principal regions; the Americas, EMEA and Asia-Pacific. The regional reporting units monitor the performance and are responsible for the agencies in their region. Agencies within the regional reporting units serve similar clients in similar industries and in many cases the same clients and have similar economic characteristics.

Revenue and long-lived assets and goodwill by geographic region at and for the three months ended March 31, 2019 and 2018 were (in millions):

	Americas		EMEA		Asia-Pacific
2019
Revenue	$	2,078.2	$	1,024.5	$	366.2
Long-lived assets and goodwill	7,703.9		3,004.3		655.8
2018
Revenue	$	2,094.1	$	1,143.5	$	392.0
Long-lived assets and goodwill	6,838.3		2,941.3		547.5

The Americas comprises North America, which includes the United States, Canada and Puerto Rico, and Latin America, which includes South America and Mexico. EMEA comprises Europe, the Middle East and Africa. Asia-Pacific comprises Australia, China, India, Japan, Korea, New Zealand, Singapore and other Asian countries. Revenue in the United States for the three months ended March 31, 2019 and 2018 was $1,884.1 million and $1,881.0 million, respectively.

The increase in long-lived assets and goodwill from 2018 to 2019 is primarily a result of recording the operating lease right-of-use assets upon the adoption of ASC 842 on January 1, 2019 (see Note 1) partially offset by the impact of changes in foreign curriencies during the quarter.

8. Income Taxes

Our effective tax rate for the first quarter of 2019increased period-over-period to 26.8% from 24.3%. In the first quarter of 2018, income tax expense was reduced by approximately $13.3 million, primarily as a result of the successful resolution of foreign tax claims during the quarter.

At March 31, 2019, our unrecognized tax benefits were $183.5 million. Of this amount, approximately $174.7 million would affect our effective tax rate upon resolution of the uncertain tax positions.

The estimated fair value of the contingent purchase price obligations is calculated in accordance with the terms of each acquisition agreement and is discounted. The fair value of debt is based on quoted market prices.

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

EXECUTIVE SUMMARY

We are a strategic holding company providing advertising, marketing and corporate communications services to clients through our branded networks and agencies around the world. On a global, pan-regional and local basis, our networks and agencies provide a comprehensive range of services in the following fundamental disciplines: advertising, CRM, which includes CRM Consumer Experience and CRM Execution & Support, public relations and healthcare. Our business model was built and continues to evolve around our clients. While our networks and agencies operate under different names and frame their ideas in different disciplines, we organize our services around our clients. Our fundamental business principle is that our clients’ specific marketing requirements are the central focus of how we structure our service offerings and allocate our resources. This client-centric business model requires that multiple agencies within Omnicom collaborate in formal and informal virtual client networks utilizing our key client matrix organization structure. This collaboration allows us to cut across our internal organizational structures to execute our clients’ marketing requirements in a consistent and comprehensive manner. We use our client-centric approach to grow our business by expanding our service offerings to existing clients, moving into new markets and obtaining new clients. In addition, we pursue selective acquisitions of complementary companies with strong entrepreneurial management teams that typically currently serve or could serve our existing clients.

As a leading global advertising, marketing and corporate communications company, we operate in all major markets and have a large and diverse client base. In the first quarter of 2019, our largest client accounted for 3.2% of our revenue and our 100 largest clients, which represent many of the world's major marketers, accounted for approximately 52% of our revenue. Our business is spread across a number of industry sectors with no one industry comprising more than 14% of our revenue for the three months ended March 31, 2019. Although our revenue is generally balanced between the United States and international markets and we have a large and diverse client base, we are not immune to general economic downturns.

As described in more detail below, in the first quarter of 2019, revenue decreased$160.7 million, or 4.4%, compared to the first quarter of 2018. Changes in foreign exchange rates reduced revenue $122.0 million, or 3.4%, acquisition revenue, net of disposition revenue, reduced revenue $130.1 million, or 3.6%, reflecting the disposition of certain non-strategic businesses, which occurred primarily in the third quarter of 2018, and organic growth increased revenue $91.4 million, or 2.5%.

Global economic conditions have a direct impact on our business and financial performance. Adverse global or regional economic conditions pose a risk that our clients may reduce, postpone or cancel spending on advertising, marketing and corporate communications services, which would reduce the demand for our services. Revenue is typically lower in the first and third quarters and higher in the second and fourth quarters, reflecting client spending patterns during the year and additional project work that usually occurs in the fourth quarter. Additionally, certain global events targeted by major marketers for advertising expenditures, such as the FIFA World Cup and the Olympics, and certain national events, such as the U.S. election process, may affect our revenue period-over-period in certain businesses. Typically, these events do not have a significant impact on our revenue in any period. In the first three months of 2019, in North America, improved organic growth in our advertising and media and healthcare businesses was partially offset by negative performance in our other service disciplines and disposition activity. In Europe, while mixed by country, most of our businesses had moderate organic growth, which was substantially offset by the disposition of Sellbytel in the third quarter of 2018. However, the economic and political conditions in the E.U., including the status of Brexit, remain uncertain. In Latin America, continued unstable economic and political conditions in Brazil contributed to weak performance and volatility in the region. In Asia modest organic growth in most countries was partially offset by negative performance in China. The economic and fiscal issues facing the countries in which we operate can cause economic uncertainty and volatility; however, the impact on our business varies by country. We monitor economic conditions closely, as well as client revenue levels and other factors and, in response to reductions in our client revenue, if necessary, we will take actions available to us to align our cost structure and manage our working capital. There can be no assurance whether, or to what extent, our efforts to mitigate any impact of future adverse economic conditions, reductions in client revenue, changes in client creditworthiness and other developments will be effective.

Certain business trends have had a positive impact on our business and industry. These trends include clients increasingly expanding the focus of their brand strategies from national markets to pan-regional and global markets and integrating traditional and non-traditional marketing channels, as well as utilizing new communications technologies and emerging digital platforms. As clients increase their demands for marketing effectiveness and efficiency, they have made it a practice to consolidate their business within one service provider in the pursuit of a single engagement covering all consumer touch points. We have structured our business around these trends. We believe that our key client matrix organization structure approach to collaboration and integration of our services and solutions has provided a competitive advantage to our business in the past and we expect this to continue over the medium and long term.

17

Driven by our clients’ continuous demand for more effective and efficient marketing activities, we strive to provide an extensive range of advertising, marketing and corporate communications services through various client-centric networks that are organized to meet specific client objectives. These services include, among others, advertising, branding, content marketing, corporate social responsibility consulting, crisis communications, custom publishing, data analytics, database management, digital/direct marketing, digital transformation, entertainment marketing, experiential marketing, field marketing, financial/corporate business-to-business advertising, graphic arts/digital imaging, healthcare marketing and communications, in-store design, interactive marketing, investor relations, marketing research, media planning and buying, merchandising and point of sale, mobile marketing, multi-cultural marketing, non-profit marketing, organizational communications, package design, product placement, promotional marketing, public affairs, public relations, retail marketing, sales support, search engine marketing, shopper marketing, social media marketing and sports and event marketing.

In the near term, barring unforeseen events and excluding the impact of changes in foreign exchange rates, because of continued improvement in operating performance by many of our agencies and new business activities, we expect our organic revenue to increase modestly for the remainder of 2019 and over the long term to be in excess of the weighted average nominal GDP growth in our major markets. We expect to continue to identify acquisition opportunities intended to build upon the core capabilities of our strategic disciplines and business platforms, expand our operations in high-growth and emerging markets and enhance our capabilities to leverage new technologies that are being used by marketers today.

We continually evaluate our portfolio of businesses to identify areas for investment and acquisition opportunities, as well as to identify non-strategic or underperforming businesses for disposition. In the first quarter of 2019 and in 2018, we disposed of certain businesses, primarily in our CRM Execution & Support discipline, and in the third quarter of 2018 we took certain repositioning actions in an effort to continue to improve our strategic position and achieve operating efficiencies. We expect the reduction to our earnings from our disposition activity to be substantially offset by the savings achieved from the operating efficiency and cost reduction activities, as well as any incremental earnings from new acquisition activity, and we expect a net reduction to revenue from net disposition activity of 3% for the current year.

Given our size and breadth, we manage our business by monitoring several financial indicators. The key indicators that we focus on are revenue and operating expenses. We analyze revenue growth by reviewing the components and mix of the growth, including growth by principal regional market and marketing discipline, the impact from foreign currency exchange rate changes, growth from acquisitions, net of dispositions and growth from our largest clients. Operating expenses are comprised of cost of services, selling, general and administrative expenses, or SG&A, and depreciation and amortization.

The change in revenue across our principal regional markets were: North America increased$3.5 million, Europe decreased$124.6 million, Asia-Pacific decreased$25.8 million and Latin America decreased$19.4 million. In North America, moderate organic growth in the United States and Canada was offset by a decrease in revenue primarily resulting from net disposition activity in the United States and the weakening of the Canadian Dollar against the U.S. Dollar. Organic revenue growth in the United States was led by our advertising and media businesses and healthcare businesses, and was substantially offset by a decrease in organic revenue growth in our CRM Execution & Support disciplines. In Europe, moderate organic growth across the region was offset by the weakening of substantially all currencies in the region against the U.S. Dollar, as well as disposition activity, and weaker performance in France. The decrease in revenue in Latin America was primarily a result of the weakening of most currencies in the region against the U.S. Dollar, negative performance in Brazil and disposition activity. In Asia-Pacific, growth in most countries in the region, especially Australia and New Zealand, was offset by the weakening of all currencies in the region against the U.S. Dollar, disposition activity, and negative performance in China, which faced a difficult comparison to the first quarter of 2018. The change in revenue in the first quarter of 2019 compared to the first quarter of 2018, in our fundamental disciplines was: advertising increased$20.0 million, CRM Consumer Experience decreased$29.1 million, CRM Execution & Support decreased$159.1 million, public relations decreased$12.1 million and healthcare increased$19.6 million.

We measure cost of services in two distinct categories: salary and service costs and occupancy and other costs. As a service business, salary and service costs make up the significant portion of our operating expenses and substantially all these costs comprise the essential components directly linked to the delivery of our services. Salary and service costs include employee compensation and benefits, freelance labor and direct service costs, which include third-party supplier costs and client-related travel costs. Occupancy and other costs consist of the indirect costs related to the delivery of our services, including office rent and other occupancy costs, equipment rent, technology costs, general office expenses and other expenses.

SG&A expenses, which decreased slightly year-over-year, primarily consist of third-party marketing costs, professional fees and compensation and benefits and occupancy and other costs of our corporate and executive offices, which includes group-wide finance and accounting, treasury, legal and governance, human resource oversight and similar costs.

18

Operating expenses in the first quarter of 2019decreased5.2% period-over-period, primarily as a result of our disposition activity in the third quarter of 2018 and the weakening of substantially all foreign currencies against the U.S. Dollar. Salary and service costs, which tend to fluctuate with changes in revenue, decreased$145.2 million, or 5.4%, in the first quarter of 2019 compared to the first quarter of 2018. Occupancy and other costs, which are less directly linked to changes in revenue than salary and service costs, decreased$11.1 million, or 3.5%, in the first quarter of 2019 compared to the first quarter of 2018. Operating margin for the first quarter of 2019 was 12.4% compared to 11.6% for the first quarter of 2018. The period-over-period increase primarily reflects a change in the mix of our business during the current period, including the positive effects following the disposition of underperforming businesses in the current and prior year and our repositioning activity in the third quarter of 2018, as well as our ongoing efforts to manage our cost structure and increase the efficiency of the operations of our agencies. In addition, a net gain on the sale of certain businesses during the quarter, partially offset by the negative impact of foreign exchange rates, marginally improved earnings before interest, taxes and amortization of intangible assets, or EBITA, margin and operating profit in the current period. EBITA margin for the first quarter of 2019 was 13.0% compared to 12.4% for the first quarter of 2018.

Net interest expense decreased$0.9 million period-over-period to $46.0 million in the first quarter of 2019. Interest expense on debt increased $3.1 million to $59.2 million in the first quarter of 2019, reflecting higher rates on the floating leg of our fixed-to-floating interest rate swaps, which was partially offset by a decrease in interest expense on commercial paper compared to the prior period. In February 2019, Omnicom Finance Limited, a wholly owned subsidiary of the Company, or OFL, issued €520 million of short-term senior notes in a private placement to an investor outside the United States. The notes are unsecured, non-interest bearing and mature on August 14, 2019. As a result, in the first quarter of 2019 we were able to substantially reduce our commercial paper issuances resulting in lower interest expense in the period. We expect that trend to continue through the maturity of the notes. Interest income increased$1.6 million period-over-period; reflecting higher cash balances available for investment.

Our effective tax rate for the first quarter of 2019increased period-over-period to 26.8% from 24.3%. In the first quarter of 2018, income tax expense was reduced by $13.3 million, primarily as a result of the successful resolution of foreign tax claims during the quarter.

Net income - Omnicom Group Inc. in the first quarter of 2019decreased$0.9 million, or 0.3%, to $263.2 million from $264.1 million in the first quarter of 2018. The period-over-period decrease is due to the factors described above. Diluted net income per share - Omnicom Group Inc. increased2.6% to $1.17 in the first quarter of 2019, compared to $1.14 in the first quarter of 2018, due to the factors described above, as well as the impact of the reduction in our weighted average common shares outstanding resulting from repurchases of our common stock, net of shares issued for restricted stock awards, stock option exercises and the employee stock purchase plan. The successful resolution of foreign tax claims during the first quarter of 2018 increased diluted net income per share - Omnicom Group Inc. for the first quarter of 2018 by $0.06.

Non-GAAP Financial Measures

We use EBITA and EBITA Margin as additional operating performance measures that exclude the non-cash amortization expense of intangible assets, which primarily consists of amortization of intangible assets arising from acquisitions. We define EBITA as earnings before interest, taxes and amortization of intangible assets, and EBITA Margin as EBITA divided by revenue. EBITA and EBITA Margin are non-GAAP Financial measures. We believe that EBITA and EBITA Margin are useful measures for investors to evaluate the performance of our business. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP. Non-GAAP financial measures reported by us may not be comparable to similarly titled amounts reported by other companies.

Revenue

In the first quarter of 2019, revenue decreased$160.7 million, or 4.4%, to $3,468.9 million from $3,629.6 million in the first quarter of 2018. Changes in foreign exchange rates reduced revenue $122.0 million, acquisition revenue, net of disposition revenue, reduced revenue $130.1 million, and organic growth increased revenue $91.4 million.

20

The impact of changes in foreign exchange rates reduced revenue 3.4%, or $122.0 million, compared to the first quarter of 2018, primarily resulting from the weakening of substantially all foreign currencies, especially the Euro, British Pound, Australian Dollar and Russian Ruble, against the U.S. Dollar.

The components of revenue change for the first quarter of 2019 in the United States (“Domestic”) and the remainder of the world (“International”) were (in millions):

	Total					Domestic					International
	$			%		$			%		$			%
March 31, 2018	$	3,629.6				$	1,881.0				$	1,748.6
Components of revenue change:
Foreign exchange rate impact	(122.0		)	(3.4	)%	—			—	%	(122.0		)	(7.0	)%
Acquisition revenue, net of disposition revenue	(130.1		)	(3.6	)%	(34.3		)	(1.8	)%	(95.8		)	(5.5	)%
Organic growth	91.4			2.5	%	37.4			2.0	%	54.0			3.1	%
March 31, 2019	$	3,468.9		(4.4	)%	$	1,884.1		0.2	%	$	1,584.8		(9.4	)%

The components and percentages are calculated as follows:

• Foreign exchange rate impact is calculated by translating the current period’s local currency revenue using the prior period average exchange rates to derive current period constant currency revenue (in this case $3,590.9 million for the Total column). The foreign exchange impact is the difference between the current period revenue in U.S. Dollars and the current period constant currency revenue ($3,468.9 million less $3,590.9 million for the Total column).

• Acquisition revenue is calculated as if the acquisition occurred twelve months prior to the acquisition date by aggregating the comparable prior period revenue of acquisitions through the acquisition date. As a result, acquisition revenue excludes the positive or negative difference between our current period revenue subsequent to the acquisition date and the comparable prior period revenue and the positive or negative growth after the acquisition is attributed to organic growth. Disposition revenue is calculated as if the disposition occurred twelve months prior to the disposition date by aggregating the comparable prior period revenue of dispositions through the disposition date. The acquisition revenue and disposition revenue amounts are netted in the table.

• Organic growth is calculated by subtracting the foreign exchange rate impact, and the acquisition revenue, net of disposition revenue components from total revenue growth.

• The percentage change is calculated by dividing the individual component amount by the prior period revenue base of that component ($3,629.6 million for the Total column).

Changes in the value of foreign currencies against the U.S. Dollar affect our results of operations and financial position. For the most part, because the revenue and expense of our foreign operations are both denominated in the same local currency, the economic impact on operating margin is minimized. Assuming exchange rates at April 15, 2019 remain unchanged, we expect the impact of changes in foreign exchange rates to reduce revenue by approximately 1.5% for the year and 2.5% in the second quarter.

Revenue in Europe, which includes our primary markets of the U.K. and the Euro Zone, decreased$124.6 million for the first quarter of 2019. Revenue in the U.K., representing 9.8% of total revenue, decreased$19.3 million primarily due to the weakening of the British Pound against the U.S. Dollar. Revenue in Continental Europe, which comprises the Euro Zone and the other European countries, representing 17.5% of total revenue decreased$105.3 million primarily due to disposition activity and the unfavorable impact from changes in foreign exchange rates.

21

In North America, moderate organic growth in the United States and Canada was offset by a decrease in revenue primarily resulting from net disposition activity in the United States and the weakening of the Canadian Dollar against the U.S. Dollar. Organic revenue growth in the United States was led by our advertising and media businesses and healthcare businesses, and was substantially offset by a decrease in organic revenue growth in our CRM Execution & Support disciplines. In Europe, moderate organic growth across the region was offset by the weakening of substantially all currencies in the region against the U.S. Dollar, disposition activity, and weaker performance in France. The decrease in revenue in Latin America was primarily a result of the weakening of most currencies in the region against the U.S. Dollar, negative performance in Brazil and disposition activity. In Asia-Pacific, growth in most countries in the region, especially Australia and New Zealand, was offset by the weakening of all currencies in the region against the U.S. Dollar, disposition activity, and negative performance in China, which faced a difficult comparison to the first quarter of 2018.

In the normal course of business, our agencies both gain and lose business from clients each year due to a variety of factors. The net change in the first quarter of 2019 was an overall gain in new business. Under our client-centric approach, we seek to broaden our relationships with all of our clients. Our largest client represented 3.2% and 3.1% of our revenue for the first quarter of 2019 and 2018, respectively. Our ten largest and 100 largest clients represented 19.2% and 51.8% of our revenue for the first quarter of 2019, respectively, and 19.8% and 52.0% of our revenue for the first quarter of 2018, respectively.

In an effort to monitor the changing needs of our clients and to further expand the scope of our services to key clients, we monitor revenue across a broad range of disciplines and group them into the following categories: advertising, CRM, which includes CRM Consumer Experience and CRM Execution & Support, public relations and healthcare.

Operating expenses in the first quarter of 2019decreased5.2% period-over-period, primarily as a result of our disposition activity in the third quarter of 2018 and the weakening of most foreign currencies against the U.S. Dollar. Salary and service costs, which tend to fluctuate with changes in revenue, decreased$145.2 million, or 5.4% in the first quarter of 2019 compared to the first quarter of 2018. Occupancy and other costs, which are less directly linked to changes in revenue than salary and service costs, decreased$11.1 million, or 3.5%, in the first quarter of 2019 compared to the first quarter of 2018. Operating margin for the first quarter of 2019 was 12.4% compared to 11.6% for the first quarter of 2018. The period-over-period increase primarily reflects a change in the mix of our business during the current period, including the positive effects following the disposition of underperforming businesses in the current and prior year and our repositioning activity in the third quarter of 2018, as well as our ongoing efforts to manage our cost structure and increase the efficiency of the operations of our agencies. In addition, a net gain on the sale of certain businesses during the quarter, partially offset by the negative impact of foreign exchange rates, marginally improved EBITA margin and operating profit in the current period. EBITA margin for the first quarter of 2019 was 13.0% compared to 12.4% for the first quarter of 2018.

Net Interest Expense

Net interest expense decreased$0.9 million period-over-period to $46.0 million in the first quarter of 2019. Interest expense on debt increased $3.1 million to $59.2 million in the first quarter of 2019; reflecting higher rates on the floating leg of our fixed-to-floating interest rate swaps, which was partially offset by a decrease in interest expense on commercial paper compared to the prior period. In February 2019, OFL issued €520 million of short-term senior notes in a private placement to an investor outside the United States. The notes are unsecured, non-interest bearing and mature on August 14, 2019. As a result, in the first quarter of 2019, we were able to substantially reduce our commercial paper issuances resulting in lower interest expense in the period. We expect that trend to continue through the maturity of the notes. Interest income increased$1.6 million period-over-period; reflecting higher cash balances available for investment.

Income Taxes

Our effective tax rate for the first quarter of 2019increased period-over-period to 26.8% from 24.3%. In the first quarter of 2018, income tax expense was reduced by $13.3 million, primarily as a result of the successful resolution of foreign tax claims during the quarter.

Net Income Per Share - Omnicom Group Inc.

Net income - Omnicom Group Inc. in the first quarter of 2019decreased$0.9 million, or 0.3%, to $263.2 million from $264.1 million in the first quarter of 2018. The period-over-period decrease is due to the factors described above. Diluted net income per share - Omnicom Group Inc. increased2.6% to $1.17 in the first quarter of 2019, compared to $1.14 in the first quarter of 2018, due to the factors described above, as well as the impact of the reduction in our weighted average common shares outstanding resulting from repurchases of our common stock, net of shares issued for restricted stock awards, stock option exercises and the employee stock purchase plan. The successful resolution of foreign tax claims during the first quarter of 2018 increased diluted net income per share - Omnicom Group Inc. for the first quarter of 2018 by $0.06.

CRITICAL ACCOUNTING POLICIES

For a more complete understanding of our accounting policies, the unaudited consolidated financial statements and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations, readers are encouraged to consider this information together with our discussion of our critical accounting policies under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2018 10-K.

NEW ACCOUNTING STANDARDS

On January 1, 2019, we adopted FASB Accounting Standards Codification, or ASC, Topic 842, Leases, or ASC 842, which had a substantial impact on total assets and liabilities, but had no impact on our results of operations or equity.

Notes 1 and 3 to the unaudited consolidated financial statements provide information regarding new accounting standards.

LIQUIDITY AND CAPITAL RESOURCES

Cash Sources and Requirements

Our primary liquidity sources are our operating cash flow, cash and cash equivalents and short-term investments. Additional liquidity sources include our credit facilities and commercial paper program, and access to the capital markets. At March 31, 2019, we have a $2.5 billion revolving credit facility, or Credit Facility, expiring on July 31, 2021, uncommitted credit lines aggregating $1.5 billion, and the ability to issue up to $2 billion of commercial paper. Our liquidity funds our non-discretionary cash requirements and our discretionary spending.

Working capital is our principal non-discretionary funding requirement. In addition, we have contractual obligations related to our senior notes, recurring business operations, primarily related to lease obligations, and contingent purchase price obligations (earn-outs) from prior acquisitions. Our principal discretionary cash spending includes dividend payments to common shareholders, capital expenditures, strategic acquisitions and repurchases of our common stock. As a result, we typically have a short-term borrowing requirement normally peaking during the second quarter of the year due to the timing of payments for incentive compensation, income taxes and contingent purchase price obligations. On January 1, 2019, we adopted ASC 842, which had a substantial impact on total assets and liabilities, but had no impact on our results of operations or equity. The adoption of ASC 842 will not have a significant impact on our non-discretionary funding requirement. Based on past performance and current expectations, we believe that our operating cash flow will be sufficient to meet our non-discretionary cash requirements and our discretionary spending for the next twelve months.

Cash and cash equivalents decreased$202.7 million from December 31, 2018, and short-term investments decreased$0.1 million from December 31, 2018. During the first three months of 2019, we used$395.6 million of cash in operating activities, which included the use for operating capital of $736.3 million, reflecting our typical working capital requirement during the period. Our discretionary spending during the first three months of 2019 was: capital expenditures of $27.2 million; dividends paid to common shareholders of $134.8 million; dividends paid to shareholders of noncontrolling interests of $17.0 million; repurchases of our common stock, net of proceeds from stock option exercises and related tax benefits and common stock sold to our employee stock purchase plan, of $284.1 million; and acquisition payments, including payment of contingent purchase price obligations and acquisition of additional shares of noncontrolling interests, net of cash acquired, of $7.2 million.

Our $500 million6.25% Senior Notes due 2019 mature on July 15, 2019 and are classified as current. In addition, because of the current low interest rate environment in the European capital markets, in the first quarter of 2019, OFL issued €520 million of short-term senior notes in a private placement to an investor outside the United States (see Note 6 to the unaudited consolidated financial statements). The notes are unsecured, non-interest bearing and mature on August 14, 2019. As a result, the Company was able to substantially reduce its commercial paper issuances in the first quarter of 2019 compared to the first quarter of 2018, resulting in lower interest expense in the period. We expect that trend to continue through the maturity of the notes.

Cash Management

Our regional treasury centers in North America, Europe and Asia manage our cash and liquidity. Each day, operations with excess funds invest these funds with their regional treasury center. Likewise, operations that require funds borrow from their regional treasury center. The treasury centers aggregate the net position which is either invested with or borrowed from third parties. To the extent that our treasury centers require liquidity, they have the ability to issue up to a total of $2 billion of U.S. Dollar-denominated commercial paper or borrow under the Credit Facility or the uncommitted credit lines. This process enables us to manage our debt more efficiently and utilize our cash more effectively, as well as manage our risk to foreign exchange rate imbalances. In countries where we either do not conduct treasury operations or it is not feasible for one of our treasury centers to fund net borrowing requirements on an intercompany basis, we arrange for local currency uncommitted credit lines.

24

We have a policy governing counterparty credit risk with financial institutions that hold our cash and cash equivalents and we have deposit limits for each institution. In countries where we conduct treasury operations, generally the counterparties are either branches or subsidiaries of institutions that are party to the Credit Facility. These institutions generally have credit ratings equal to or better than our credit ratings. In countries where we do not conduct treasury operations, all cash and cash equivalents are held by counterparties that meet specific minimum credit standards.

At March 31, 2019, our foreign subsidiaries held approximately $900 million of our total cash and cash equivalents of $3.4 billion. Most of the cash is available to us, net of any foreign withholding taxes payable upon repatriation to the United States.

Our net debt position, which we define as total debt, including short-term debt, less cash and cash equivalents and short-term investments, at March 31, 2019increased$808.2 million as compared to December 31, 2018. The increase in net debt is due to a decrease in cash and cash equivalents and short-term investments of $202.8 million primarily arising from the unfavorable change in our operating capital of $736.3 million, which typically occurs in the first half of the year.

The components of net debt as of March 31, 2019, December 31, 2018 and March 31, 2018 were (in millions):

	March 31, 2019		December 31, 2018		March 31, 2018
Short- term debt	$	595.4	$	8.1	$	8.6
Long-term debt, including current portion	4,901.8		4,883.7		4,885.0
Total debt	5,497.2		4,891.8		4,893.6
Less: Cash and cash equivalents and short-term investments	3,455.1		3,657.9		2,570.0
Net debt	$	2,042.1	$	1,233.9	$	2,323.6

Net debt is a Non-GAAP liquidity measure. This presentation, together with the comparable U.S. GAAP liquidity measures, reflects one of the key metrics used by us to assess our cash management. Non-GAAP liquidity measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP. Non-GAAP liquidity measures as reported by us may not be comparable to similarly titled amounts reported by other companies.

Debt Instruments and Related Covenants

At March 31, 2019, the total principal amount of our fixed rate senior notes was $4.9 billion and the total notional amount of the fixed-to-floating interest rate swaps was $1.25 billion. The interest rate swaps have the economic effect of converting our debt portfolio to approximately 75% fixed rate obligations and 25% floating rate obligations. In addition, during the first quarter of 2019, OFL issued, and Omnicom guaranteed, €520 million of short-term senior notes (see Note 6 to the unaudited consolidated financial statements).

Omnicom and its wholly owned finance subsidiary, Omnicom Capital Inc., or OCI, are co-obligors under all the senior notes (other than the OFL notes). The senior notes are a joint and several liability of us and OCI, and we unconditionally guarantee OCI’s obligations with respect to the senior notes. OCI provides funding for our operations by incurring debt and lending the proceeds to our operating subsidiaries. OCI’s assets primarily consist of cash and cash equivalents and intercompany loans made to our operating subsidiaries, and the related interest receivable. There are no restrictions on the ability of OCI or us to obtain funds from our subsidiaries through dividends, loans or advances. Our senior notes are senior unsecured obligations that rank equal in right of payment with all existing and future unsecured senior indebtedness.

The Credit Facility contains financial covenants that require us to maintain a Leverage Ratio of consolidated indebtedness to consolidated EBITDA of no more than 3 times for the most recently ended 12-month period (EBITDA is defined as earnings before interest, taxes, depreciation and amortization) and an Interest Coverage Ratio of consolidated EBITDA to interest expense of at least 5 times for the most recently ended 12-month period. At March 31, 2019, we were in compliance with these covenants as our Leverage Ratio was 2.3 times and our Interest Coverage Ratio was 9.8 times. The Credit Facility does not limit our ability to declare or pay dividends or repurchase our common stock.

At March 31, 2019, our long-term and short-term debt was rated BBB+ and A2 by S&P and Baa1 and P2 by Moody's. Our access to the commercial paper market and the cost of these borrowings are affected by our credit ratings and market conditions. Our senior notes and Credit Facility do not contain provisions that require acceleration of cash payments in the event our debt credit ratings are downgraded.

Credit Markets and Availability of Credit

We have typically funded our day-to-day liquidity by issuing commercial paper. Additional liquidity sources include our Credit Facility or the uncommitted credit lines. At March 31, 2019, there were no outstanding commercial paper issuances or borrowings under the Credit Facility or the uncommitted credit lines.

25

Commercial paper activity for the three months ended March 31, 2019 and 2018 was (dollars in millions):

	2019			2018
Average amount outstanding during the quarter	$	—		$	305.4
Maximum amount outstanding during the quarter	$	—		$	971.5
Average days outstanding	—			3.9
Weighted average interest rate	—		%	1.84		%

Due to the issuance of the €520 million senior notes by OFL, as described above, there were no issuances of commercial paper during the first quarter of 2019.

We may continue to fund our day-to-day liquidity by issuing commercial paper. However, disruptions in the credit markets may lead to periods of illiquidity in the commercial paper market and higher credit spreads. To mitigate any future disruption in the credit markets and to fund our liquidity, we may borrow under the Credit Facility or access the capital markets if favorable conditions exist. We will continue to monitor closely our liquidity and conditions in the credit markets. We cannot predict with any certainty the impact on us of any future disruptions in the credit markets. In such circumstances, we may need to obtain additional financing to fund our day-to-day working capital requirements. Such additional financing may not be available on favorable terms, or at all.

CREDIT RISK

We provide advertising, marketing and corporate communications services to several thousand clients who operate in nearly every sector of the global economy and we grant credit to qualified clients in the normal course of business. Due to the diversified nature of our client base, we do not believe that we are exposed to a concentration of credit risk as our largest client represented 3.2% of our revenue for the first three months of 2019. However, during periods of economic downturn, the credit profiles of our clients could change.

In the normal course of business, our agencies enter into contractual commitments with media providers and production companies on behalf of our clients at levels that can substantially exceed the revenue from our services. These commitments are included in accounts payable when the services are delivered by the media providers or production companies. If permitted by local law and the client agreement, many of our agencies purchase media and production services for our clients as an agent for a disclosed principal. In addition, while operating practices vary by country, media type and media vendor, in the United States and certain foreign markets, many of our agencies’ contracts with media and production providers specify that our agencies are not liable to the media and production providers under the theory of sequential liability until and to the extent we have been paid by our client for the media or production services.

Where purchases of media and production services are made by our agencies as a principal or are not subject to the theory of sequential liability, the risk of a material loss as a result of payment default by our clients could increase significantly and such a loss could have a material adverse effect on our business, results of operations and financial position.

In addition, our methods of managing the risk of payment default, including obtaining credit insurance, requiring payment in advance, mitigating the potential loss in the marketplace or negotiating with media providers, may be less available or unavailable during a severe economic downturn.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We manage our exposure to foreign exchange and interest rate risk through various strategies, including the use of derivative financial instruments. We use forward foreign exchange contracts as economic hedges to manage the cash flow volatility arising from foreign exchange rate fluctuations. We use interest rate swaps to manage our interest expense and structure our long-term debt portfolio to achieve a mix of fixed rate and floating rate debt. We do not use derivatives for trading or speculative purposes. Using derivatives exposes us to the risk that counterparties to the derivative contracts will fail to meet their contractual obligations. We manage that risk through careful selection and ongoing evaluation of the counterparty financial institutions based on specific minimum credit standards and other factors.

Our 2018 10-K provides a detailed discussion of the market risks affecting our operations. No material change has occurred in our market risks since the disclosure contained in our 2018 10-K. See our discussion regarding current economic conditions in Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations, in the Executive Summary and Liquidity and Capital Resources sections.

ITEM 4. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports we file with the SEC is recorded, processed, summarized and reported within applicable time periods. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is accumulated and communicated to management, including our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, as appropriate to allow timely decisions regarding required disclosure. Management, including our CEO and CFO, conducted an evaluation of the effectiveness of our disclosure controls and procedures as of March 31, 2019. Based on that evaluation, our CEO and CFO concluded that, as of March 31, 2019, our disclosure controls and procedures are effective to ensure that decisions can be made timely with respect to required disclosures, as well as ensuring that the recording, processing, summarization and reporting of information required to be included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2019 are appropriate.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Management, with the participation of our CEO, CFO and our agencies, conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, our CEO and CFO concluded that our internal control over financial reporting was effective as of March 31, 2019. There have not been any changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

KPMG LLP, an independent registered public accounting firm that audited our consolidated financial statements included in our 2018 10-K, has issued an attestation report on Omnicom’s internal control over financial reporting as of December 31, 2018, dated February 12, 2019.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

In the ordinary course of business, we are involved in various legal proceedings. We do not presently expect that these proceedings will have a material adverse effect on our results of operations or financial position.

Item 1A. Risk Factors

There have been no material changes to the risk factors disclosed in Item 1A in our 2018 10-K.

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

Common stock repurchases during the three months ended March 31, 2019 were:

Period	Total Number of Shares Purchased	Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number of Shares that May Yet Be Purchased Under the Plans or Programs
January 1 - 31, 2019	177,947	$	72.59	—	—
February 1 - 28, 2019	877,573	75.39		—	—
March 1 - 31, 2019	2,766,900	74.84		—	—
	3,822,420	$	74.86	—	—

During the three months ended March 31, 2019, we purchased 3,785,000 shares of our common stock in the open market for general corporate purposes and withheld 37,420 shares from employees to satisfy estimated statutory income tax obligations related to stock option exercises and vesting of restricted stock. The value of the common stock withheld was based on the closing price of our common stock on the applicable exercise or vesting date.

There were no unregistered sales of our equity securities during the three months ended March 31, 2019.

Presentation of Financial Statements

Presentation of Financial Statements

The terms “Omnicom,” “the Company,” “we,” “our” and “us” each refer to Omnicom Group Inc. and its subsidiaries, unless the context indicates otherwise. The accompanying unaudited consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP or GAAP, for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission, or SEC. Accordingly, certain information and footnote disclosure have been condensed or omitted.

In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation, in all material respects, of the information contained herein. These unaudited consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018, or 2018 10-K. Results for the interim periods are not necessarily indicative of results that may be expected for the year.

Accounting Changes

Except for the changes discussed below, Omnicom has consistently applied the accounting policies to all periods presented in these unaudited consolidated financial statements.

Adoption of ASC 842

On January 1, 2019, we adopted FASB Accounting Standards Codification, or ASC, Topic 842, Leases, or ASC 842, which requires the recognition of the right-of-use assets and related operating and finance lease liabilities on the balance sheet. As permitted by ASC 842, we elected the adoption date of January 1, 2019, which is the date of initial application. As a result, the consolidated balance sheet prior to January 1, 2019 was not restated, continues to be reported under ASC Topic 840, Leases, or ASC 840, which did not require the recognition of operating lease liabilities on the balance sheet, and is not comparative. Under ASC 842, all leases are required to be recorded on the balance sheet and are classified as either operating leases or finance leases. The lease classification affects the expense recognition in the income statement. Operating lease charges are recorded entirely in operating expenses. Finance lease charges are split, where amortization of the right-of-use asset is recorded in operating expenses and an implied interest component is recorded in interest expense. The expense recognition for operating leases and finance leases under ASC 842 is substantially consistent with ASC 840. As a result, there is no significant difference in our results of operations presented in our consolidated income statement and consolidated statement of comprehensive income for each period presented.

We adopted ASC 842 using a modified retrospective approach for all leases existing at January 1, 2019. The adoption of ASC 842 had a substantial impact on our balance sheet. The most significant impact was the recognition of the operating lease right-of-use assets and the liability for operating leases. The accounting for finance leases (capital leases) was substantially unchanged. Accordingly, upon adoption, leases that were classified as operating leases under ASC 840 were classified as operating leases under ASC 842, and we recorded an adjustment of $1,490.1 million to operating lease right-of-use assets and the related lease liability. The lease liability is based on the present value of the remaining minimum lease payments, determined under ASC 840, discounted using our secured incremental borrowing rate at the effective date of January 1, 2019, using the original lease term as the tenor. As permitted under ASC 842, we elected several practical expedients that permit us to not reassess (1) whether a contract is or contains a lease, (2) the classification of existing leases, and (3) whether previously capitalized costs continue to qualify as initial indirect costs. The application of the practical expedients did not have a significant impact on the measurement of the operating lease liability.

The impact of the adoption of ASC 842 on the balance sheet at December 31, 2018 was (in millions):

	As Reported December 31, 2018		Adoption of ASC 842 Increase (Decrease)			Balance January 1, 2019
Other current assets	$	1,241.4	$	(29.2	)	$	1,212.2
Operating lease right-of-use assets	—		1,306.5			1,306.5
Total assets	24,617.0		1,277.3			25,894.3
Other current liabilities	1,958.6		172.5			2,131.1
Long-term liability - Operating leases	—		1,258.5			1,258.5
Long-term liabilities	1,197.8		(153.7		)	1,044.1
Total liabilities and equity	24,617.0		1,277.3			25,894.3

We lease substantially all our office space, technology equipment and office equipment used to conduct our business. We adopted ASC 842 effective January 1, 2019. For contracts entered into on or after the effective date, at the inception of a contract we assess whether the contract is, or contains, a lease. Our assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether we have the right to direct the use of the asset. At inception of a lease, we allocate the consideration in the contract to each lease component based on its relative stand-alone price to determine the lease payments. Leases entered into prior to January 1, 2019, are accounted for under ASC 840 and were not reassessed.

Leases are classified as either finance leases or operating leases. A lease is classified as a finance lease if any one of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it does not meet any one of these criteria. Substantially all our operating leases are comprised of office space leases, and substantially all our finance leases are comprised of office furniture and technology equipment.

For all leases at the lease commencement date, a right-of-use asset and a lease liability are recognized. The right-of-use asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease.

The right-of-use asset is initially measured at cost, which primarily comprises the initial amount of the lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All right-of-use assets are reviewed for impairment. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our secured incremental borrowing rate for the same term as the underlying lease. For our real estate and other operating leases, we use our secured incremental borrowing rate. For our finance leases, we use the rate implicit in the lease or our secured incremental borrowing rate if the implicit lease rate cannot be determined.

Lease payments included in the measurement of the lease liability comprise the following: the fixed noncancelable lease payments, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early.

Some of our real estate leases contain variable lease payments, including payments based on an index or rate. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement and separated into lease and non-lease components based on the initial amount stated in the lease or standalone selling prices. Lease components are included in the measurement of the initial lease liability. Additional payments based on the change in an index or rate, or payments based on a change in our portion of the operating expenses, including real estate taxes and insurance, are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability.

Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage commissions, and is recognized on a straight-line basis over the lease term. Included in lease expense are any variable lease payments incurred in the period that were not included in the initial lease liability. Lease expense for finance leases consists of the amortization of the right-of-use asset on a straight-line basis over the lease term and interest expense determined on an amortized cost basis. The lease payments are allocated between a reduction of the lease liability and interest expense.

We have elected not to recognize right-of-use assets and lease liabilities for short-term leases that have a term of 12 months or less. The effect of short-term leases on our right-of-use asset and lease liability was not material.

Adoption of ASU 2018-02

On January 1, 2019, we adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income: Reclassification of Certain Tax effects from Accumulated Other Comprehensive Income, or ASU 2018-02, which requires the reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects arising from the change in the reduction of the U.S. federal statutory income tax rate to 21% from 35%. The tax effects of items included in accumulated comprehensive income at December 31, 2017 did not reflect the appropriate tax rate. The adoption of ASU 2018-02 resulted in reclassification between accumulated other comprehensive income and retained earnings of $22.3 million, and had no impact on our results of operations or financial position.

New Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. We will adopt ASU 2016-13 on January 1, 2020. However, we are not yet in a position to assess the impact of the new standard on our results of operations or financial position.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other, Internal-Use Software, or ASU 2018-15, which aligns the accounting for implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted at any interim period. ASU 2018-15 may be adopted either on a prospective basis upon early adoption or the effective date for implementation costs for new or existing arrangements incurred on or after the adoption date, or on a full retrospective basis to the earliest period presented. We are not yet in a position to assess the adoption date or the adoption method or to assess impact of the new standard on our results of operations or financial position.

Credit Facilities

At March 31, 2019, our short-term liquidity sources include a $2.5 billion revolving credit facility, or Credit Facility, expiring on July 31, 2021, uncommitted credit lines aggregating $1.5 billion and the ability to issue up to $2 billion of commercial paper.

There were no outstanding commercial paper issuances or borrowings under the Credit Facility or the uncommitted credit lines at March 31, 2019 and December 31, 2018. Available and unused credit lines at March 31, 2019 and December 31, 2018 were (in millions):

Uncommitted credit lines	1,479.3		1,231.6
Available and unused credit lines	$	3,979.3	$	3,731.6

The Credit Facility contains financial covenants that require us to maintain a Leverage Ratio of consolidated indebtedness to consolidated EBITDA of no more than 3 times for the most recently ended 12-month period (EBITDA is defined as earnings before interest, taxes, depreciation and amortization) and an Interest Coverage Ratio of consolidated EBITDA to interest expense of at least 5 times for the most recently ended 12-month period.At March 31, 2019 we were in compliance with these covenants as our Leverage Ratio was 2.3 times and our Interest Coverage Ratio was 9.8 times. The Credit Facility does not limit our ability to declare or pay dividends or repurchase our common stock.

Short-Term Debt

In February 2019, Omnicom Finance Limited, a wholly owned subsidiary of Omnicom, or OFL, issued €520 million of short-term senior notes in a private placement to an investor outside the United States. The notes are unsecured, non-interest bearing and mature on August 14, 2019. The notes are fully and unconditionally guaranteed by Omnicom and rank equal in right of payment with all existing and future unsecured senior indebtedness of OFL. The notes are redeemable in full at OFL's option on June 14, 2019 at a redemption price equal to 100% of the principal amount. Short-term debt at March 31, 2019 and December 31, 2018 was $595.4 million and $8.1 million, respectively. Due to its short-term nature, the carrying value of the short-term debt approximates fair value.

Long-Term Debt

Long-term debt at March 31, 2019 and December 31, 2018 was (in millions):

	2019			2018
6.25% Senior Notes due 2019	$	500.0		$	500.0
4.45% Senior Notes due 2020	1,000.0			1,000.0

Current portion	(499.8		)	(499.6		)
Long-term debt	$	4,402.0		$	4,384.1

Omnicom and its wholly owned finance subsidiary, Omnicom Capital Inc., or OCI, are co-obligors under all the senior notes. The senior notes are a joint and several liability of us and OCI, and we unconditionally guarantee OCI’s obligations with respect to the senior notes. OCI provides funding for our operations by incurring debt and lending the proceeds to our operating subsidiaries. OCI’s assets primarily consist of cash and cash equivalents and intercompany loans made to our operating subsidiaries, and the related interest receivable. There are no restrictions on the ability of OCI or us to obtain funds from our subsidiaries through dividends, loans or advances. Our senior notes are senior unsecured obligations that rank equal in right of payment with all existing and future unsecured senior indebtedness.

At March 31, 2019, we recorded a long-term liability of $9.8 million in connection with the $750 million fixed-to-floating interest rate swap on our 3.65% Senior Notes due 2024, or 2024 Notes, and a long-term liability of $21.0 million in connection with the $500 million fixed-to-floating interest rate swap on our 3.60% Senior Notes due 2026, or 2026 Notes. The liabilities represent the fair value of the swaps on the 2024 Notes and 2026 Notes that was substantially offset by the change in the fair value of the notes. The fixed-to-floating interest rate swaps have the economic effect of converting our debt portfolio to approximately 75% fixed rate obligations and 25% floating rate obligations.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

Our five branded agency networks operate in the advertising, marketing and corporate communications services industry, and are organized into agency networks, virtual client networks, regional reporting units and operating groups or practice areas. Our networks, virtual client networks and agencies increasingly share clients and provide clients with integrated services. The main economic components of each agency are employee compensation and related costs and direct service costs and occupancy and other costs which include rent and occupancy costs, technology costs and other overhead expenses. Therefore, given these similarities, we aggregate our operating segments, which are our five agency networks, into one reporting segment.

The agency networks' regional reporting units comprise three principal regions; the Americas, EMEA and Asia-Pacific. The regional reporting units monitor the performance and are responsible for the agencies in their region. Agencies within the regional reporting units serve similar clients in similar industries and in many cases the same clients and have similar economic characteristics.

Revenue and long-lived assets and goodwill by geographic region at and for the three months ended March 31, 2019 and 2018 were (in millions):

Revenue	$	2,094.1	$	1,143.5	$	392.0
Long-lived assets and goodwill	6,838.3		2,941.3		547.5

The Americas comprises North America, which includes the United States, Canada and Puerto Rico, and Latin America, which includes South America and Mexico. EMEA comprises Europe, the Middle East and Africa. Asia-Pacific comprises Australia, China, India, Japan, Korea, New Zealand, Singapore and other Asian countries. Revenue in the United States for the three months ended March 31, 2019 and 2018 was $1,884.1 million and $1,881.0 million, respectively.

The increase in long-lived assets and goodwill from 2018 to 2019 is primarily a result of recording the operating lease right-of-use assets upon the adoption of ASC 842 on January 1, 2019 (see Note 1) partially offset by the impact of changes in foreign curriencies during the quarter.

Our effective tax rate for the first quarter of 2019increased period-over-period to 26.8% from 24.3%. In the first quarter of 2018, income tax expense was reduced by approximately $13.3 million, primarily as a result of the successful resolution of foreign tax claims during the quarter.

At March 31, 2019, our unrecognized tax benefits were $183.5 million. Of this amount, approximately $174.7 million would affect our effective tax rate upon resolution of the uncertain tax positions.

The estimated fair value of the contingent purchase price obligations is calculated in accordance with the terms of each acquisition agreement and is discounted. The fair value of debt is based on quoted market prices.
