NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Presentation of Financial Statements

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

In our opinion, the accompanying unaudited condensed financial statements reflect all adjustments, consisting of normally recurring accruals, considered necessary for a fair presentation, in all material respects, of the information contained herein. These unaudited condensed financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2011 (“2011 Form 10-K”). Results for the interim periods are not necessarily indicative of results that may be expected for the year.

2. New Accounting Standards

On January 1, 2012, FASB Accounting Standards Update No. 2011-08, Testing Goodwill for Impairment ("ASU 2011-08") became effective. This standard gives an entity the option of performing a qualitative assessment to determine whether it is necessary to perform step 1 of the annual goodwill impairment test. An entity is required to perform step 1 only if it concludes that it is more likely than not that a reporting unit's fair value is less than its carrying amount. An entity may choose to perform the qualitative assessment on none, some or all of its reporting units or an entity may bypass the qualitative assessment for any reporting unit in any period and proceed directly to step 1 of the impairment test. We perform our annual impairment test at the end of the second quarter of each year.

6. Segment Reporting

Our wholly and partially owned agencies operate within the advertising, marketing and corporate communications services industry. These agencies are organized into agency networks, virtual client networks, regional reporting units and operating groups. Consistent with our fundamental business strategy, our agencies serve similar clients, in similar industries and, in many cases, the same clients across a variety of geographic regions. In addition, our agency networks have similar economic characteristics including similar costs and long-term profit contribution. The main economic components of each agency are employee compensation and related costs and direct service costs and office and general 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.

9. Equity Method Investments

Effective February 1, 2011, we acquired a controlling interest in the Clemenger Group, our affiliate in Australia and New Zealand, increasing our equity ownership to 73.7% from 46.7%. In connection with this transaction we recorded a remeasurement gain of $123.4 million. The difference between the fair value of our shares at the acquisition date and the carrying value of our investment prior to the acquisition resulted in the remeasurement gain. The remeasurement gain was included in office and general expenses for the quarter ended March 31, 2011.

10. Repositioning Actions

In the first quarter of 2011, in connection with a continuing review of our businesses focused on enhancing our strategic position, improving our operations and rebalancing our workforce, we recorded $131.3 million of charges related to repositioning actions for severance, real estate lease terminations and asset and goodwill write-offs related to disposals and other costs.

Repositioning actions for the three months ended March 31, 2011 were (in millions):

Severance	$	92.8

Real estate lease terminations and asset and goodwill write-offs related to disposals and other costs were included in office and general expenses for the quarter ended March 31, 2011. Substantially all the severance and real estate lease termination payments were made as of December 31, 2011. All other costs are primarily non-cash items.

11. Supplemental Cash Flow Data

Changes in operating capital for the three months ended March 31, 2012 and 2011 were (in millions):

	2012			2011
Decrease in accounts receivable	$	796.5		$	729.6
Increase in work in process and other current assets	(163.6		)	(203.1		)

Change in operating capital	$	(311.0	)	$	(352.6	)
Income taxes paid	$	123.0		$	86.7
Interest paid	$	41.1		$	49.3

12. Income Taxes

At March 31, 2012, our unrecognized tax benefits were $159.3 million. Of this amount, approximately $61.7 million would affect our effective tax rate upon resolution of the uncertain tax positions.

Our effective tax rate for the first quarter of 2012 increased to 32.8%, compared to 25.5% for the first quarter of 2011. Income tax expense for the three months ended March 31, 2011 includes a $39.5 million tax benefit related to charges incurred in connection with our repositioning actions, a provision of $2.8 million related to the remeasurement gain and a provision of $9.0 million for agreed upon adjustments to income tax returns that were under examination in the first quarter of 2011. Excluding the effect of these items, our effective tax rate for the quarter ended March 31, 2011 would have been 34.1%.

The tax benefit on the repositioning actions was calculated based on the jurisdictions where the charges were incurred and reflects the likelihood that we will be unable to obtain a tax benefit for all charges incurred. The remeasurement gain resulting from the acquisition of the controlling interest in Clemenger created a difference between the book basis and tax basis of our investment. Because this basis difference is not expected to reverse, no deferred taxes were provided and the tax provision recorded represents the incremental U.S. tax on acquired historical unremitted earnings. The $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, that were agreed upon and recorded in the first quarter of 2011. The examination of those returns is closed.

13. Commitments and Contingent Liabilities

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.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Short-term investments.Short-term investments primarily consist of time deposits with financial institutions that we expect to convert into cash within our current operating cycle, generally one year. Short-term investments are carried at cost, which approximates fair value.

Available-for-sale securities.Available-for-sale securities are carried at quoted market prices.

Cost method investments.Cost method investments are carried at cost, which approximates or is less than fair value.

Short-term borrowings.Short-term borrowings consist of bank overdrafts and credit lines of our international subsidiaries. Due to the short-term nature of these instruments, carrying value approximates fair value.

Forward foreign exchange contracts.The estimated fair value of derivative positions in forward foreign exchange contracts is determined using model-derived valuations, taking into consideration market rates and counterparty credit risk.

Debt.Debt includes fixed rate debt and convertible debt. The fair value of these instruments is based on quoted market prices.

Item2.  Management's Discussion And Analysis Of Financial Condition And Results Of Operations

Executive Summary

We are a strategic holding company. We provide professional services to clients through multiple agencies around the world. On a global, pan-regional and local basis, our agencies provide these services in the following disciplines: advertising, customer relationship management, or CRM, public relations and specialty communications. Our business model was built and continues to evolve around our clients. While our agencies operate under different names and frame their ideas in different disciplines, we organize our services around our clients. The fundamental premise of our business is that our clients’ specific requirements should be the central focus in how we deliver our services and allocate our resources. This client-centric business model results in multiple agencies collaborating in formal and informal virtual networks that cut across internal organizational structures to deliver consistent brand messages for a specific client and execute against each of our clients’ specific marketing requirements. We continually seek to grow our business with our existing clients by maintaining our client-centric approach, as well as expanding our existing business relationships into new markets and with new clients. In addition, we pursue selective acquisitions of complementary companies with strong entrepreneurial management teams that typically serve or have the ability to serve our existing client base.

As a leading global advertising, marketing and corporate communications company, we operate in all major markets around the world. We have a large and diverse client base. Our largest client accounted for 2.5% of our revenue for the three months ended March 31, 2012 and no other client accounted for more than 2.4% of our revenue. Our top 100 clients accounted for approximately 50% of our revenue for the three months ended March 31, 2012. Our business is spread across a significant number of industry sectors with no one industry comprising more than 16% of our revenue for the three months ended March 31, 2012. 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.

In the first three months of 2012, our revenue increased 5.0% compared to the first three months of 2011. The increase reflects strong operating performance by our agencies and an improvement in business conditions in our industry over 2011, partially offset by the negative impact from foreign exchange rates. Revenue increased across most of our disciplines and geographic areas driven by strong operating performance in most of the markets we operate in and continued growth in the emerging markets of Asia and Latin America.

Our business and financial performance are impacted by global economic conditions. In the first quarter of 2012, the United States experienced modest economic growth and the major economies of Asia and Latin America continued to expand. However, Europe continued to experience widespread uncertainty, and in many markets economic difficulty. If the economic conditions worsen, the downturn may expand beyond Europe and could cause reductions in client spending levels and adversely affect our results of operations and financial position. We will continue to closely monitor economic conditions, client spending and other factors, and in response to reductions in client spending, if necessary, we will take actions available to us to align our cost structure and manage working capital. There can be no assurance whether, or to what extent, our efforts to mitigate any impact of future economic conditions, reductions in client spending patterns, changes in client creditworthiness and other developments will be effective.

In the near term, barring unforeseen events and excluding foreign exchange impacts, as a result of increases in client spending and new business activities, we expect our 2012 revenue to increase modestly in excess of the weighted average nominal GDP growth in our major markets. We also expect to continue to identify acquisition opportunities that will build on the core capabilities of our strategic business platforms, expand our operations in the emerging markets and enhance our capabilities to leverage new technologies that are being used by marketers today.

Certain business trends have had a positive impact on our business and industry. These trends include our 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. Additionally, in an effort to gain greater efficiency and effectiveness from their total marketing budgets, clients are increasingly requiring greater coordination of marketing activities and concentrating these activities with a smaller number of service providers. We believe these trends have benefited our business in the past and over the medium and long term will continue to provide a competitive advantage to us.

Effective February 1, 2011, we acquired a controlling interest in the Clemenger Group, our affiliate in Australia and New Zealand increasing our equity ownership to 73.7% from 46.7%. In connection with this transaction, we recorded a non-cash gain of $123.4 million in the first quarter of 2011 resulting from the remeasurement of the carrying value of our equity interest

12

to the acquisition date fair value. This acquisition has and will continue to help us to further develop our combined businesses throughout the Asia Pacific region and further enhance our global capabilities.

We have an objective of improving EBITA margins to 2007 levels for the full year 2012. In connection with this objective, during 2011 we reviewed our businesses with a focus on enhancing our strategic position, improving our operations and rebalancing our workforce. As part of this process, we disposed of certain non-core and underperforming businesses and repositioned others. As a result of these actions, we incurred charges of $131.3 million in the first quarter of 2011 for severance, real estate lease terminations and asset and goodwill write-offs related to disposals and other costs. While the bulk of this process is behind us, we continue to review of all our businesses and we will take actions, where appropriate, to reposition underperforming businesses. We will also continue to pursue operational consolidations to further drive efficiencies in our back office functions.

Given our size and breadth, we manage our business by monitoring several financial indicators. The key indicators that we review focus on revenue and operating expenses.

We analyze revenue growth by reviewing the components and mix of the growth, including growth by major geographic location, growth by major marketing discipline, impact from currency fluctuations, growth from acquisitions and growth from our largest clients. In recent years, our revenue has been divided almost evenly between our domestic and international operations. For the quarter ended March 31, 2012, our total reported revenue increased 5.0% compared to the quarter ended March 31, 2011, of which 5.1% was organic growth and 1.0% was related to acquisitions, net of dispositions. The impact of foreign exchange rates reduced revenue by 1.1%. Across our geographic markets revenue increased 4.0% in the United States, 2.4% in the United Kingdom and 17.5% in our other markets, primarily Asia and Latin America, while revenue decreased 5.2% in our Euro markets. The change in revenue in the first quarter of 2012 compared to the first quarter of 2011 in our four fundamental disciplines was as follows: advertising increased 8.3%, CRM increased 2.4%, public relations increased 6.5% and specialty communications decreased 3.7%.

We measure operating expenses in two distinct cost categories: salary and service costs and office and general expenses. Salary and service costs are primarily comprised of employee compensation and related costs and direct service costs. Office and general expenses are primarily comprised of rent and occupancy costs, technology costs, depreciation and amortization and other overhead expenses. Each of our agencies requires professionals with a skill set that is common across our disciplines. At the core of this skill set is the ability to understand a client’s brand or product and its selling proposition and the ability to develop a unique message to communicate the value of the brand or product to the client’s target audience. The facility requirements of our agencies are also similar across geographic regions and disciplines, and their technology requirements are generally limited to personal computers, servers and off-the-shelf software. Because we are a service business, we monitor salary and service costs and office and general costs in relation to revenue.

Salary and service costs tend to fluctuate in conjunction with changes in revenue. Salary and service costs increased $16.1 million in the first quarter of 2012 compared to the first quarter of 2011. Salary and service costs for the first quarter of 2011 reflect $92.8 million of severance charges associated with our repositioning actions.

Office and general expenses are less directly linked to changes in our revenue than salary and service costs. Office and general expenses increased $99.5 million in the first quarter of 2012 compared to the first quarter of 2011. Office and general expenses for the first quarter of 2011 reflect a decrease of $123.4 million related to the non-cash remeasurement gain recorded n connection with the acquisition of the controlling interest in the Clemenger Group, partially offset by $38.5 million of charges related to our repositioning actions.

Operating margins increased to 11.0% in 2012 from 10.2% in 2011 and EBITA margins increased to 11.7% in the first quarter of 2012 from 10.9% in the first quarter of 2011. Excluding the $131.3 million of respositioning actions and the $123.4 remeasurement gain, operating margin and EBITA margin for the first quarter of 2011 would have been 10.5% and 11.1%, respectively. The year-over-year margin improvement was driven by our strong revenue growth, as well as lower operating costs resulting from the repositioning actions taken in the first quarter of 2011, as well as other actions taken in 2011 to improve our operations, rebalance our workforce and drive efficiencies in our back office functions.

Our effective tax rate for the first quarter of 2012 increased to 32.8%, compared to 25.5% for the first quarter of 2011. Income tax expense for the three months ended March 31, 2011 reflects a number of items that were recorded in the first quarter of 2011. These items include a $39.5 million tax benefit related to charges incurred in connection with our repositioning actions, a provision of $2.8 million related to the remeasurement gain and a provision of $9.0 million for agreed upon adjustments to income tax returns that were under examination in the first quarter of 2011.

The tax benefit on the repositioning actions was calculated based on the jurisdictions where the charges were incurred and reflects the likelihood that we will be unable to obtain a tax benefit for all charges incurred. The remeasurement gain resulting

13

from the acquisition of the controlling interest in Clemenger created a difference between the book basis and tax basis of our investment. Because this basis difference is not expected to reverse, no deferred taxes were provided and the tax provision recorded represents the incremental U.S. tax on acquired historical unremitted earnings. The $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, that were agreed upon and recorded in the first quarter of 2011. The examination of those returns is closed.

Net income - Omnicom Group Inc. in the first quarter of 2012 increased $2.7 million, or 1.3%, to $204.6 million from $201.9 million in the first quarter of 2011. The period-over-period increase in net income - Omnicom Group Inc. is due to the factors described above. Diluted net income per common share - Omnicom Group Inc. increased 4.3% to $0.72 in the first quarter of 2012, compared to $0.69 in the first quarter of 2011 due to the factors described above, as well as the reduction in our weighted average common shares outstanding. This reduction was the result of repurchases of our common stock during 2011 through the first quarter of 2012, net of stock option exercises and shares issued under our employee stock purchase plan.

EBITA, which we define as earnings before interest, taxes and amortization of intangible assets, and EBITA Margin, which we define as EBITA divided by Revenue, are Non-GAAP measures. We use EBITA and EBITA Margin as additional operating performance measures, which exclude the non-cash amortization expense of acquired intangible assets. The table above reconciles EBITA and EBITA Margin to the U.S. GAAP financial measure of Operating Income for the periods presented. We believe that EBITA and EBITA Margin are useful measures to evaluate the performance of our businesses. 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: Revenue for the first quarter of 2012 increased $156.0 million, or 5.0%, to $3,307.3 million from $3,151.3 million in the first quarter of 2011. Organic growth increased revenue by $160.9 million and acquisitions, net of dispositions, increased revenue by $31.1 million. The impact of foreign exchange rates reduced revenue by $36.0 million.

The components of the first quarter of 2012 revenue change in the United States (“Domestic”) and the remainder of the world (“International”) were (in millions)

	Total					Domestic					International
	$			%		$			%		$			%
Quarter ended March 31, 2011	$	3,151.3				$	1,652.5				$	1,498.8
Components of revenue change:
Foreign exchange impact	(36.0		)	(1.1	)%	—			—	%	(36.0		)	(2.4	)%
Acquisitions, net of dispositions	31.1			1.0	%	(6.5		)	(0.4	)%	37.6			2.5	%
Organic growth	160.9			5.1	%	73.3			4.4	%	87.6			5.8	%
Quarter ended March 31, 2012	$	3,307.3		5.0	%	$	1,719.3		4.0	%	$	1,588.0		6.0	%

The components and percentages are calculated as follows:

• The foreign exchange impact is calculated by first converting the current period’s local currency revenue using the average exchange rates from the equivalent prior period to arrive at a constant currency revenue (in this case $3,343.3 million for the Total column in the table). The foreign exchange impact equals the difference between the current period revenue in U.S. dollars and the current period revenue in constant currency (in this case $3,307.3 million less $3,343.3 million for the Total column in the table).

• The acquisition component is calculated by aggregating the applicable prior period revenue of the acquired businesses, less revenue of any business included in the prior period revenue that was disposed of subsequent to the period.

• Organic growth is calculated by subtracting both the foreign exchange and acquisition 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 (in the case $3,151.3 million for the Total column in the table).

Revenue for the first quarter of 2012 and the percentage change from the first quarter of 2011 in our primary geographic markets were (in millions):

	Revenue		% Change
United States	$	1,719.3	4.0	%
Euro Markets	547.6		(5.2	)%
United Kingdom	286.8		2.4	%
Other	753.6		17.5	%
	$	3,307.3	5.0	%

For the first quarter of 2012, foreign exchange rate impacts reduced revenue by 1.1%, or $36.0 million, compared to the first quarter of 2011. The most significant impacts resulted from the strengthening of the U.S. Dollar against the British Pound and the Euro.

Assuming exchange rates at April 13, 2012 remain unchanged, we expect foreign exchange impacts to decrease revenue by less than 2% for the full year 2012.

Due to a variety of factors, in the normal course, our agencies both gain and lose business from clients each year. The net result in 2011 was an overall gain in new business. Under our client-centric approach, we seek to broaden our relationships with all of our clients. Revenue from our largest client accounted for 2.5% and 3.1% of our revenue for the first quarter of 2012 and 2011, respectively. No other client represented more than 2.4% and 2.3% of revenue for the first quarter of 2012 and 2011, respectively. Our ten largest and 100 largest clients represented 18.8% and 51.2% of our revenue for the first quarter of 2012, respectively and 18.7% and 49.2% of our revenue for the first quarter of 2011, respectively.

15

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 advertising, brand consultancy, corporate social responsibility consulting, crisis communications, custom publishing, data analytics, database management, direct marketing, entertainment marketing, environmental design, experiential marketing, field marketing, financial/corporate business-to-business advertising, interactive marketing, marketing research, media planning and buying, mobile marketing, multi-cultural marketing, non-profit marketing, public affairs, public relations, recruitment communications, reputation consulting, retail marketing, search engine marketing, social media marketing and sports and event marketing. 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 four categories: advertising, CRM, public relations and specialty communications.

Revenue for the the first quarter of 2012 and 2011 and revenue change by discipline was (in millions):

	Three Months Ended March 31,
	2012				2011				2012 vs 2011
	$		% of Revenue		$		% of Revenue		$			% Change
Advertising	$	1,550.1	46.9	%	$	1,431.0	45.4	%	$	119.1		8.3	%
CRM	1,201.7		36.3	%	1,173.9		37.3	%	27.8			2.4	%
Public relations	306.9		9.3	%	288.2		9.1	%	18.7			6.5	%
Specialty communications	248.6		7.5	%	258.2		8.2	%	(9.6		)	(3.7	)%
	$	3,307.3			$	3,151.3			$	156.0		5.0	%

Looking ahead to the remainder of the year, barring unforeseen events and excluding foreign rate exchange impacts, we expect our revenue to increase in excess of the weighted average nominal GDP growth as a result of increases in client spending and new business activities.

Operating Expenses: Operating expenses for the first quarter of 2012 compared to operating expenses for the first quarter of 2011 were (in millions):

Repositioning Actions and Remeasurement Gain: In the first quarter of 2011, we recorded $131.3 million of charges related to our repositioning actions. Additionally, we recorded a $123.4 million remeasurement gain related to the acquisition of the controlling interest in the Clemenger Group in the first quarter of 2011. The impact on operating expenses of these transactions for the three months ended March 31, 2011 was (dollars in millions):

	Increase (Decrease)
	Repositioning Actions		Remeasurement Gain
Salary and service costs	$	92.8	$	—
Office and general expenses	38.5		(123.4		)
	$	131.3	$	(123.4	)

Operating Expenses: Salary and service costs tend to fluctuate in conjunction with changes in revenue. Salary and service costs increased $16.1 million in the first quarter of 2012 compared to the first quarter of 2011. This increase reflects growth in our business, as well as increased compensation costs, including freelance labor and incentive compensation. The first quarter of 2011 included approximately $92.8 million of charges related to our repositioning actions.

Office and general expenses are less directly linked to changes in our revenue than salary and service costs. Office and general expenses increased $99.5 million in the first quarter of 2012 compared to the first quarter of 2011. Office and general expenses for the first quarter of 2011 reflect a decrease of $84.9 million, which included the $123.4 million non-cash remeasurement gain recorded in connection with the acquisition of the controlling interest in the Clemenger Group and $38.5 million of charges related to our repositioning actions.

Operating margins increased to 11.0% in 2012 from 10.2% in 2011 and EBITA margins increased to 11.7% in the first quarter of 2012 from 10.9% in the first quarter of 2011. Excluding the $131.3 million of respositioning actions and the $123.4 remeasurement gain, operating margin and EBITA margin for the first quarter of 2011 would have been 10.5% and 11.1%, respectively. The year-over-year margin improvement was driven by our strong revenue growth, as well as lower operating costs resulting from the repositioning actions taken in the first quarter of 2011, as well as other actions taken in 2011 to improve our operations, rebalance our workforce and drive efficiencies in our back office functions.

Net Interest Expense: Net interest expense decreased to $29.2 million in the first quarter of 2012, compared to $32.1 million in the first quarter of 2011. Interest expense decreased $3.4 million to $38.5 million. The reduction in interest expense is attributable to a decrease in foreign and other borrowings. Interest income decreased $0.5 million to $9.3 million in the first quarter of 2012. The decrease in interest income is attributable to lower foreign cash balances available for investment.

Income Taxes: Our effective tax rate for the first quarter of 2012 increased to 32.8%, compared to 25.5% for the first quarter of 2011. The effective tax rate for the first quarter of 2011 was effected by the following items recorded (dollars in millions):

	Increase (Decrease)
	Income Before Income Taxes			Income Tax Expense
Repositioning actions	$	(131.3	)	$	(39.5	)
Remeasurement gain	123.4			2.8
Accrual for uncertain tax positions	—			9.0
	$	(7.9	)	$	(27.7	)

The tax benefit on the repositioning actions was calculated based on the jurisdictions where the charges were incurred and reflects the likelihood that we will be unable to obtain a tax benefit for all charges incurred. The remeasurement gain resulting from the acquisition of the controlling interest in Clemenger created a difference between the book basis and tax basis of our investment. Because this basis difference is not expected to reverse, no deferred taxes were provided and the tax provision

17

recorded represents the incremental U.S. tax on acquired historical unremitted earnings. The $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, that were agreed upon and recorded in the first quarter of 2011. The examination of those returns is closed.

Net Income Per Common Share - Omnicom Group Inc.: For the foregoing reasons, net income - Omnicom Group Inc. in the first quarter of 2012 increased $2.7 million, or 1.3%, to $204.6 million, compared to $201.9 million in the first quarter of 2011. Diluted net income per common share - Omnicom Group Inc. increased 4.3% to $0.72 in the first quarter of 2012, compared to $0.69 in the first quarter of 2011 due to the factors described above, as well as the impact of the reduction in our weighted average common shares outstanding. This reduction was the result of repurchases of our common stock during 2011 through the first quarter of 2012, net of stock option exercises and shares issued under our employee stock purchase plan.

Liquidity and Capital Resources

Cash Sources and Requirements, Including Contractual Obligations

Historically, the majority of our non-discretionary cash requirements have been funded from operating cash flow and cash on hand. Working capital is our principal non-discretionary funding requirement. In addition, we have contractual obligations related to our senior notes and convertible notes, our recurring business operations, primarily related to lease obligations, as well as certain contingent acquisition obligations (earn-outs) related to acquisitions made in prior years.

Our principal discretionary cash requirements include dividend payments to our shareholders, capital expenditures, payments for strategic acquisitions and repurchases of our common stock. In addition, we pay dividends to shareholders of noncontrolling interests in our subsidiaries.

Our discretionary spending is funded from operating cash flow and cash on hand. In addition, depending on the level of our discretionary activity, we may use other available sources of funding such as issuing commercial paper, borrowing under our Credit Agreement or other long-term borrowings to finance these activities. We expect that we should be able to fund both our discretionary and non-discretionary cash requirements for the remainder of 2012 without incurring additional long-term debt. However, we may access the capital markets at any time if favorable conditions exist.

We have a seasonal cash requirement normally peaking during the second quarter primarily due to the timing of payments for incentive compensation, income taxes and contingent acquisition obligations. This typically results in a net borrowing requirement that decreases over the course of the year and at the end of the calendar year we expect to have cash invested.

At March 31, 2012, our cash and cash equivalents decreased by $278.5 million from December 31, 2011. During the first three months of 2012, we used $0.5 million of cash in operations. Our discretionary spending during the period was comprised primarily of: dividend payments of $69.8 million, capital expenditures of $45.6 million, repurchases of our common stock of $254.7 million and acquisition payments of $30.4 million. Our total discretionary spending for the three months ended March 31, 2012 was $400.5 million compared to $641.6 million for the three months ended March 31, 2011.

Cash Management

We manage our cash and liquidity centrally through our regional treasury centers in North America, Europe and Asia. The regional treasury centers are managed by our wholly-owned finance subsidiaries. Each day, operations with excess funds invest these funds with their regional treasury center. Likewise, operations that require funding borrow funds 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 access local currency uncommitted lines of credit or the Credit Agreement or issue up to a total of $1.5 billion of U.S. Dollar-denominated commercial paper. This process enables us to manage our debt balances more efficiently and utilize our cash more effectively, as well as better manage our risk to foreign exchange changes. 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 lines of credit.

18

Our cash and cash equivalents decreased $278.5 million and our short-term investments decreased $18.0 million from December 31, 2011. Short-term investments principally consist of time deposits with financial institutions that we expect to convert into cash within our current operating cycle, generally one year.

At March 31, 2012, our foreign subsidiaries held $1,428.4 million of our cash and cash equivalents. These funds are used to manage the day-to-day liquidity requirements of our international operations. The majority of this cash is available to us, net of any taxes payable upon repatriation to the United States. Changes in international tax rules or changes in U.S. tax rules and regulations covering international operations and foreign tax credits may affect our future reported financial results or the way we conduct our business.

We have policies governing counterparty credit risk with banks that hold our cash and cash equivalents. Generally, in countries where we conduct treasury operations, the bank counterparties are either branches or subsidiaries of institutions that are party to our Credit Agreement. These banks have credit ratings equal to or better than our credit ratings. We have risk management limits for each of these banks and we monitor the global exposure on a daily basis. In countries where we do not conduct treasury operations, we ensure that all cash is held by bank counterparties that meet criteria based on credit ratings and other factors.

Debt Instruments and Related Covenants

We have committed and uncommitted lines of credit. We have a $2.5 billion committed line of credit ("Credit Agreement") with a consortium of banks expiring on October 12, 2016. The Credit Agreement provides support for outstanding commercial paper issuances, as well as back-up liquidity in the event that any of our convertible notes are put back to us. Outstanding commercial paper issuances are considered the equivalent of drawings under the Credit Agreement.

Depending on market conditions at the time, we typically fund our day-to-day liquidity by issuing commercial paper, borrowing under our uncommitted lines of credit or drawing on our Credit Agreement. At March 31, 2012, there were no outstanding commercial paper issuances or borrowings under the Credit Agreement.

For the quarter ended March 31, 2012, commercial paper activity was (dollars in millions):

Average amount outstanding during the quarter	$	353.8
Maximum amount outstanding during the quarter	$	683.8
Total issuances during the quarter	$	4,271.4
Average days outstanding	7.5
Weighted average interest rate	0.40		%

At March 31, 2012, we had short-term borrowings of $11.7 million that were comprised of bank overdrafts and lines of credit of our international subsidiaries. These bank overdrafts and lines of credit are treated as unsecured loans pursuant to the bank agreements supporting the facilities.

The Credit Agreement contains financial covenants that restrict our ability to incur indebtedness as defined in the agreement. These financial covenants limit the ratio of total consolidated indebtedness to total consolidated EBITDA (under the Credit Agreement, EBITDA is defined as earnings before interest, taxes, depreciation and amortization) to no more than 3.0 times. We are also required to maintain a minimum ratio of consolidated EBITDA to interest expense of at least 5.0 times. At March 31, 2012, we were in compliance with these covenants, as our ratio of debt to EBITDA was 1.6 times and our ratio of EBITDA to interest expense was 12.9 times. The Credit Agreement does not limit our ability to declare or pay dividends.

19

At March 31, 2012, outstanding debt, amounts available under the Credit Agreement, unamortized discount and deferred gain on interest rate swaps were (in millions):

	Debt Outstanding			Available Credit
Short-term borrowings (due in less than one year)	$	11.7		$	—

Credit Markets and Availability of Credit

We will continue to take actions available to us to respond to changing economic conditions and actively manage our discretionary expenditures. We will continue to monitor and manage the level of credit made available to our clients. We believe that these actions, in addition to the availability of our Credit Agreement, are sufficient to fund our working capital needs and our discretionary spending.

In funding our day-to-day liquidity, we have historically been a participant in the commercial paper market. We expect to continue funding our day-to-day liquidity through the commercial paper market. However, prior disruptions in the credit markets led to periods of illiquidity in the commercial paper market and higher credit spreads. During these periods of disruption, we used our uncommitted lines of credit and borrowed under our Credit Agreement to mitigate these conditions and to fund our day-to-day liquidity. We will continue to closely monitor our liquidity and the credit markets. We cannot predict with any certainty the impact on us of any future disruptions in the credit markets.

The next date on which holders of our 2032 Notes can put their notes back to us for cash is July 31, 2012. The next date on which holders of our 2038 Notes can put their notes back to us for cash is June 17, 2013. If our convertible notes are put back to us, based on our current financial condition and expectations, we expect to have sufficient available cash and unused credit commitments to fund any repurchase. Although such borrowings would reduce the amount available under our Credit Agreement to fund our cash requirements, we believe that we have sufficient capacity under these commitments to meet our cash requirements for the normal course of our business operations after any repurchase.

Credit Risk

We provide marketing and corporate communications services to thousands of clients who operate in nearly every industry sector of the global economy and in the normal course of business, we grant credit to qualified clients. 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 accounted for 2.5% of our revenue for the first quarter of 2012 and no other client accounted for more than 2.4% of our revenue for the first quarter of 2012. However, during periods of economic downturn, the credit profiles of our clients could change.

In the normal course of business, we often enter into contractual commitments with media providers and agreements with production companies on behalf of our clients at levels that can substantially exceed the revenue from our services. Many of our agencies purchase media for our clients and act as an agent for a disclosed principal. These commitments are included in accounts payable when the media services are delivered by the media providers. While operating practices vary by country, media type and media vendor, in the United States and certain foreign markets, many of our contracts with media providers specify that if our client defaults on its payment obligation, then we are not liable to the media providers under the theory of sequential liability until we have been paid for the media by our client. In other countries, we manage our risk in other ways,

20

including evaluating and monitoring our clients’ creditworthiness and in many cases, obtaining credit insurance or requiring payment in advance. Further, in cases where we are committed to a media purchase and it becomes apparent that a client may be unable to pay for the media, options are potentially available to us in the marketplace, in addition to those cited above to mitigate the potential loss, including negotiating with media providers. In addition, our agencies incur production costs on behalf of clients. We usually act as an agent for a disclosed principal in the procurement of these services. We manage the risk of payment default by the client by having the production companies be subject to sequential liability or requiring at least partial payment in advance from our client. However, the agreements entered into, as well as the production costs incurred, are unique to each client. We have not experienced a material loss related to media purchases or production costs incurred on behalf of our clients. However, the risk of a material loss could significantly increase in a severe economic downturn.

ITEM 3. QUANTATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As a global service business, we operate in multiple foreign currencies and issue debt in the capital markets. In the normal course of business, we are exposed to foreign currency fluctuations and the impact of interest rate changes. We limit these risks through risk management policies and procedures, including the use of derivatives. For foreign currency exposure, derivatives are used to better manage the cash flow volatility arising from foreign exchange rate fluctuations. For interest rate exposure, derivatives have been used to manage the related cost of debt.

As a result of using derivative instruments, we are exposed to the risk that counterparties to derivative contracts will fail to meet their contractual obligations. To mitigate the counterparty credit risk, we have a policy of only entering into contracts with carefully selected major financial institutions based on credit ratings and other factors.

Our 2011 Form 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 2011 Form 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 our SEC reports 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 our reports that 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. We conducted an evaluation of the effectiveness of our disclosure controls and procedures as of March 31, 2012. Based on that evaluation, our CEO and CFO concluded that, as of March 31, 2012, 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, 2012 are appropriate.

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 2011 Form 10-K, has issued an attestation report on Omnicom’s internal control over financial reporting as of December 31, 2011, dated February 17, 2012.

New Accounting Standards

On January 1, 2012, FASB Accounting Standards Update No. 2011-08, Testing Goodwill for Impairment ("ASU 2011-08") became effective. This standard gives an entity the option of performing a qualitative assessment to determine whether it is necessary to perform step 1 of the annual goodwill impairment test. An entity is required to perform step 1 only if it concludes that it is more likely than not that a reporting unit's fair value is less than its carrying amount. An entity may choose to perform the qualitative assessment on none, some or all of its reporting units or an entity may bypass the qualitative assessment for any reporting unit in any period and proceed directly to step 1 of the impairment test. We perform our annual impairment test at the end of the second quarter of each year.

Lines of Credit

We have committed and uncommitted lines of credit. We have a $2.5 billion committed line of credit ("Credit Agreement") with a consortium of banks expiring on October 12, 2016. We have the ability to classify borrowings under the Credit Agreement as long-term. The Credit Agreement provides support for up to $1.5 billion of commercial paper issuances, as well

as back-up liquidity in the event that any of our convertible notes are put back to us. The issuance of commercial paper reduces the amount available under the Credit Agreement. At March 31, 2012, there were no outstanding commercial paper issuances or borrowings under the Credit Agreement. At March 31, 2012 and December 31, 2011, we had various uncommitted lines of credit aggregating $765.7 million and $758.3 million, respectively.

Our available and unused lines of credit at March 31, 2012 and December 31, 2011 were (in millions):

	2012		2011
Credit Agreement	$	2,500.0	$	2,500.0

Short-Term Borrowings

Short-term borrowings of $11.7 million and $9.5 million at March 31, 2012 and December 31, 2011, respectively, are primarily comprised of bank overdrafts and credit lines of our international subsidiaries. The bank overdrafts and credit lines are treated as unsecured loans pursuant to the bank agreements supporting the facilities.

Income Taxes

At March 31, 2012, our unrecognized tax benefits were $159.3 million. Of this amount, approximately $61.7 million would affect our effective tax rate upon resolution of the uncertain tax positions.

Our effective tax rate for the first quarter of 2012 increased to 32.8%, compared to 25.5% for the first quarter of 2011. Income tax expense for the three months ended March 31, 2011 includes a $39.5 million tax benefit related to charges incurred in connection with our repositioning actions, a provision of $2.8 million related to the remeasurement gain and a provision of $9.0 million for agreed upon adjustments to income tax returns that were under examination in the first quarter of 2011. Excluding the effect of these items, our effective tax rate for the quarter ended March 31, 2011 would have been 34.1%.

The tax benefit on the repositioning actions was calculated based on the jurisdictions where the charges were incurred and reflects the likelihood that we will be unable to obtain a tax benefit for all charges incurred. The remeasurement gain resulting from the acquisition of the controlling interest in Clemenger created a difference between the book basis and tax basis of our investment. Because this basis difference is not expected to reverse, no deferred taxes were provided and the tax provision recorded represents the incremental U.S. tax on acquired historical unremitted earnings. The $9.0 million charge resulted from adjustments to U.S. income tax returns for calendar years 2005, 2006 and 2007, that were agreed upon and recorded in the first quarter of 2011. The examination of those returns is closed.

Segment Reporting

Our wholly and partially owned agencies operate within the advertising, marketing and corporate communications services industry. These agencies are organized into agency networks, virtual client networks, regional reporting units and operating groups. Consistent with our fundamental business strategy, our agencies serve similar clients, in similar industries and, in many cases, the same clients across a variety of geographic regions. In addition, our agency networks have similar economic characteristics including similar costs and long-term profit contribution. The main economic components of each agency are employee compensation and related costs and direct service costs and office and general 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.

Equity Method Investments

Effective February 1, 2011, we acquired a controlling interest in the Clemenger Group, our affiliate in Australia and New Zealand, increasing our equity ownership to 73.7% from 46.7%. In connection with this transaction we recorded a remeasurement gain of $123.4 million. The difference between the fair value of our shares at the acquisition date and the carrying value of our investment prior to the acquisition resulted in the remeasurement gain. The remeasurement gain was included in office and general expenses for the quarter ended March 31, 2011.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Short-term investments.Short-term investments primarily consist of time deposits with financial institutions that we expect to convert into cash within our current operating cycle, generally one year. Short-term investments are carried at cost, which approximates fair value.

Available-for-sale securities.Available-for-sale securities are carried at quoted market prices.

Cost method investments.Cost method investments are carried at cost, which approximates or is less than fair value.

Short-term borrowings.Short-term borrowings consist of bank overdrafts and credit lines of our international subsidiaries. Due to the short-term nature of these instruments, carrying value approximates fair value.

Forward foreign exchange contracts.The estimated fair value of derivative positions in forward foreign exchange contracts is determined using model-derived valuations, taking into consideration market rates and counterparty credit risk.

Debt.Debt includes fixed rate debt and convertible debt. The fair value of these instruments is based on quoted market prices.
