Notes to Consolidated Financial Statements

March 31, 2013

(unaudited)

1. Basis of Presentation and Consolidation

Presentation

The accompanying unaudited consolidated financial statements of Arbitron Inc. (the “Company” or “Arbitron”) have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included and are of a normal recurring nature. The consolidated balance sheet as of December 31, 2012 was audited as of that date, but all of the information and notes as of December 31, 2012 required by GAAP have not been included in this Form 10-Q. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Certain amounts in the consolidated financial statements for prior periods have been reclassified to conform to the current period’s presentation.

Consolidation

The consolidated financial statements of Arbitron for the three-month period ended March 31, 2013, reflect the consolidated financial position, results of operations and cash flows of the Company and its wholly-owned subsidiaries: Arbitron Holdings Inc., Arbitron Mobile Oy, Astro West LLC, Cardinal North LLC, Ceridian Infotech (India) Private Limited, Arbitron International, LLC, and Arbitron Technology Services India Private Limited. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has one segment which meets the quantitative thresholds for being a reportable segment.

2. New Accounting Pronouncements

Testing Other Intangibles for Impairment. In July 2012, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2012-02, Intangibles — Goodwill and Other (Topic 350) — Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”), to allow entities to use a qualitative approach to test indefinite-lived assets for impairment. ASU 2012-02 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of the intangible asset is less than its carrying value. If it is concluded that this is the case, it is necessary to calculate the fair value of the intangible asset and perform the quantitative impairment test. Otherwise, the entity need not perform the quantitative impairment test. ASU 2012-02 is effective for the Company for interim and annual periods ended during 2013. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

Comprehensive Income Presentation. In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220) Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”), to require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. ASU 2013-02 is effective for the Company beginning with interim and annual periods ended during 2013. The Company adopted this guidance during the current interim period ended March 31, 2013, and disclosed the appropriate information within the consolidated financial statements and notes to the financial statements for the periods presented therein.

3. Pending Merger with Nielsen Holdings N.V.

On December 17, 2012, the Company entered into an Agreement and Plan of Merger, as amended by Amendment No. 1 to the Agreement and Plan of Merger, dated as of January 25, 2013, with Nielsen Holdings N.V. (“Nielsen”) and TNC Sub I Corporation, a Delaware corporation and an indirect wholly-owned subsidiary of Nielsen (“Merger Sub”), pursuant to which, subject to satisfaction or waiver of the conditions therein, Merger Sub will merge with and into the Company (the “Merger”) with Arbitron surviving as an indirect wholly-owned subsidiary of Nielsen. The transaction has been approved by the boards of both companies. On April 16, 2013, the Company’s shareholders approved the adoption of the Merger. The Merger remains subject to certain regulatory approvals, including expiration of the Hart-Scott-Rodino antitrust waiting period, and customary closing conditions. For additional information regarding the business risks associated with pursuing the Merger, see Item 1A. Risk Factors — Risk Factors Relating to the Merger, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 filed with the SEC.

4. Stockholders’ Equity

Changes in stockholders’ equity for the three-month period ended March 31, 2013, were as follows (in thousands):

	Shares Outstanding		Common Stock		Treasury Stock			Retained Earnings			Accumulated Other Comprehensive Loss			Total Stockholders’ Equity
Balance as of December 31, 2012		26,624	$	16,169	$	(2,857	)	$	156,530		$	(16,433	)	$	153,409

A quarterly cash dividend of $0.10 per common share was paid to stockholders during the quarter ended March 31, 2013.

5. Net Income per Weighted-Average Common Share

The computations of basic and diluted net income per weighted-average common share for the three-month periods ended March 31, 2013, and 2012, are based on the Company’s weighted-average shares of common stock and potentially dilutive securities outstanding. Potentially dilutive securities are calculated in accordance with the treasury stock method, which assumes the proceeds from the exercise of all dilutive stock options are used to repurchase the Company’s common stock at the average market price for the period.

As of March 31, 2013, and 2012, there were stock options to purchase 1,549,251 shares, and 2,105,924 shares of the Company’s common stock outstanding, respectively, of which stock options to purchase 148,426 shares, and 1,238,880 shares of the Company’s common stock, respectively, were excluded from the computation of the diluted net income per weighted-average common share for the three-month periods ended March 31, 2013, and 2012, respectively, either because the stock options’ exercise prices were greater than the average market price of the Company’s common shares or assumed repurchases from proceeds from the stock options’ exercise were antidilutive.

6. Accumulated Other Comprehensive Loss

The changes in accumulated other comprehensive loss for the three months ended March 31, 2013, and 2012, were as follows (in thousands):

		Three-Month Period ended March 31, 2013										Three-Month Period ended March 31, 2012
		Foreign currency items			Retirement plan items				Total			Foreign currency items			Retirement plan items				Total
Beginning balance	{a}	$	(2,238	)	$	(14,195	)		$	(16,433	)	$	(2,148	)	$	(13,453	)		$	(15,601	)

{a} All amounts are net of tax. Amounts in parentheses indicate debits.

{b} These components were reclassified, gross of tax, as part of net periodic cost associated with the amortization of the actuarial loss related to the Company’s benefit plan obligations. See Note 7 for additional details.

7. Retirement Plans

Certain of the Company’s United States employees participate in a defined-benefit pension plan that closed to new participants effective January 1, 1995. The Company has a nonqualified, unfunded supplemental retirement plan, as well as a postretirement healthcare plan for eligible retired employees who participate in the pension plan and were hired before January 1, 1992. The components of periodic benefit costs for the defined-benefit pension, postretirement healthcare and supplemental retirement plans were as follows for the three-month periods ended March 31, 2013, and 2012 (in thousands):

		Defined-Benefit Pension Plan Three-Month Period Ended March 31,						Postretirement Healthcare Plan Three-Month Period Ended March 31,				Supplemental Retirement Plan Three-Month Period Ended March 31,
		2013			2012			2013		2012		2013		2012
Service cost		$	254		$	215		$	9	$	8	$	12	$	7
Interest cost			470			476			15		18		39		40
Expected return on plan assets			(559	)		(509	)		—		—		—		—
Amortization of net actuarial loss	{a}		564			473			2		6		57		48
Net periodic benefit cost		$	729		$	655		$	26	$	32	$	108	$	95

{a} The total amount of amortization of net actuarial loss for all retirement plans was $623 and $527 for the three-month periods ended March 31, 2013, and 2012, respectively.

8. Arbitron Mobile Contingent Consideration

On July 28, 2011, a wholly-owned subsidiary of the Company acquired Zokem Oy, which is now being consolidated as Arbitron Mobile. The purchase price was $10.6 million in cash plus a contingent consideration arrangement. The contingent consideration arrangement provides for possible additional cash payments to be made by the Company to the former Zokem Oy shareholders through 2015 of up to $12.0 million, which are contingent upon Arbitron Mobile reaching certain financial performance targets in the future. The Company periodically reassesses the fair value of the contingent consideration by applying the income approach method. The key assumptions used in the fair value valuation include a probability-weighted range of performance targets for the four-year measurement period of 2012 through 2015 and an adjusted discount rate. As of both March 31, 2013 and December 31, 2012, the Company’s fair value estimate of the contingent consideration was $0.6 million, which is recorded as a portion of noncurrent liabilities on the Company’s consolidated balance sheet.

9. Taxes

The effective tax rate increased to 41.5% for the three-month period ended March 31, 2013, from 38.1% for the three-month period ended March 31, 2012. This increase for the three-month period ended March 31, 2013, as compared to the same period of 2012, resulted primarily from certain nondeductible transaction costs anticipated during 2013 in relation to the pending Merger.

During the three-month period ended March 31, 2013, the Company’s unrecognized tax benefits for certain tax contingencies decreased from $1.3 million as of December 31, 2012, to $1.1 million as of March 31, 2013. The decrease is primarily attributable to the settlement of various state income tax audits. If recognized, the $1.1 million in unrecognized tax benefits would reduce the Company’s effective tax rate in future periods. Income taxes paid for the three-month periods ended March 31, 2013 and 2012, were $0.4 million and $0.3 million, respectively.

11

10. Share-Based Compensation

The following table sets forth information with regard to the income statement recognition of share-based compensation for the three-month periods ended March 31, 2013, and 2012 (in thousands):

	Three-Month Period Ended March 31, 2013		Three-Month Period Ended March 31, 2012
Cost of revenue	$	55	$	146
Selling, general and administrative		2,118		1,922
Research and development		76		100
Share-based compensation	$	2,249	$	2,168

No share-based compensation cost was capitalized during the three-month periods ended March 31, 2013, and 2012.

Stock Options

Stock options awarded to employees under the Company’s 2008 Equity Compensation Plan (“2008 Plan”) generally vest annually over a three-year period, have a 10-year term and have an exercise price equal to the fair market value of the Company’s common stock at the date of grant. Compensation expense for stock options is recognized on a straight-line basis over the vesting period using the fair value of each stock option estimated as of the grant date.

For the three-month period ended March 31, 2013, no stock options were granted. For the three-month period ended March 31, 2012, the number of stock options granted was 93,955, and the weighted-average exercise price for those stock options granted was $33.87.

As of March 31, 2013, there was $2.5 million in total unrecognized compensation cost related to unvested stock options. This aggregate unrecognized cost is expected to be recognized over a weighted-average remaining period of 1.9 years. The weighted-average exercise price and weighted-average remaining contractual term for outstanding stock options as of March 31, 2013, were $33.69 and 5.6 years, respectively.

Service and Performance Award Units

Service award units to employees. The Company granted service award units under the 2008 Plan. These service award units (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) generally vest in equal annual installments over four years beginning on the first anniversary date of the grant, except for service award units granted to the Company’s executives since December 30, 2012, which vest in 12 equal quarterly installments following the date of the grant for the CEO and 16 equal quarterly installments following the date of grant for the Company’s other executives, and (iii) for any unvested units, expire without vesting if the employee is no longer employed by the Company.

Service award units to Board of Directors (“Board”). For 2012, the Board members had the right to elect to receive all or a portion of their annual compensation as Board service award units. These Board service award units (i) were issued at the fair market value of the Company’s common stock on the date of grant, and (ii) vest on the anniversary date of the grant.

Compensation expense for service award units is recognized on a straight-line basis over the vesting period using the fair market value of the Company’s common stock on the date of grant. As of March 31, 2013, there was $8.1 million of total unrecognized compensation cost related to unvested service award units. This aggregate unrecognized cost for service award units is expected to be recognized over a weighted-average period of approximately 3.5 years.

12

Additional information for the three-month periods ended March 31, 2013, and 2012, is noted in the following table (dollars in thousands, except per share amounts):

Total Service Award Units Granted	Three-Month Period Ended March 31, 2013		Three-Month Period Ended March 31, 2012
Number of service award units granted during the period		114,705		—
Weighted average grant-date fair value per share granted during the period	$	46.79		—
Fair value of service award shares vested during the period	$	392	$	448

Performance award units. During the three-month period ended March 31, 2013, the Company did not grant any performance award units. During the three-month period ended March 31, 2012, the Company granted performance award units under the 2008 Plan. These performance award units (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) will vest in four equal annual installments beginning with the first anniversary date of the grant, and (iii) for any unvested units, expire without vesting if the recipient is no longer employed by the Company. The performance goal for these performance award units was met.

Compensation expense for performance award units is recognized (i) using the fair market value of the Company’s common stock on the date of grant, and (ii) on a graded basis, which is accelerated as compared to a straight-line expense attribution method. As of March 31, 2013, there was $1.1 million of total unrecognized compensation cost related to unvested performance award units. This aggregate unrecognized cost is expected to be recognized over a weighted-average period of 2.3 years.

Deferred Stock Units

Service DSU grants to former CEO. Prior to 2013, the Company granted service-based deferred stock unit awards (“Service DSUs”) under the 2008 Plan to its then current CEO, whose employment with the Company ended during the first quarter of 2013. These Service DSUs were granted at the fair market value of the Company’s stock on the date of grant, and generally vest annually over a four-year period on each anniversary date of the grant. Service DSUs also include dividend equivalent DSUs, which vest immediately upon the date of grant.

Compensation expense for Service DSUs was recognized on a straight-line basis over the vesting period using the fair market value of the Company’s common stock on the date of grant. The Service DSUs provide for accelerated vesting upon termination without cause or the former CEO’s retirement as defined in his employment agreement. As of March 31, 2013, there was no unrecognized compensation cost related to Service DSUs.

The Service DSUs are convertible into shares of the Company’s common stock, following the holder’s termination of employment, in accordance with the former CEO’s employment agreement. Additional information for the three-month periods ended March 31, 2013, and 2012, is noted in the following table (dollars in thousands, except per share amounts):

Fair value of shares vested during the period	$	707	$	572

Performance DSU grant to former CEO. Prior to 2013, the Company granted performance-based deferred stock unit awards (“Performance DSUs”) under the 2008 Plan to its then current CEO, whose employment with the Company ended during the first quarter of 2013. These Performance DSUs (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) will vest in four equal annual installments beginning on the first anniversary date of the grant, and (iii) provide for accelerated vesting upon termination without cause or the former CEO’s retirement as defined in his employment agreement. These Performance DSUs are convertible into shares of the Company’s common stock, subsequent to termination of employment, in accordance with the former CEO’s employment agreement.

Compensation expense for Performance DSUs was recognized (i) using the fair market value of the Company’s common stock on the date of grant, and (ii) on a graded basis, which is accelerated as compared to a straight-line expense attribution method. As of March 31, 2013, there was no unrecognized compensation cost related to Performance DSUs granted to the Company’s former CEO.

Deferred Stock Unit Awards for service on Board of Directors (“Board”). The Company issues deferred stock units to its Board of Directors (“Board DSUs”) under the 2008 Plan. These Board DSUs (i) were issued at the fair market value of the Company’s common stock on the date of grant and (ii) if vested, will be convertible to shares of the Company’s common stock subsequent to termination of service as a director. For 2012, the Board members had the right to elect to receive all or a portion of their annual compensation as Board DSUs that vest completely on the first anniversary date of the grant. For 2011 and 2010, annual grants were issued to the Board as Board DSUs that vest annually in three equal installments over three-year periods.

During the three-month period ended March 31, 2012, the Board members had the right to elect to receive all or a portion of their retainer and meeting attendance fees as Board DSUs, which vest immediately. Board DSUs are only granted to nonemployee Directors. Board DSUs also include dividend equivalent DSUs, which vest immediately upon the date of grant.

Compensation expense for Board DSUs is recognized on a straight-line basis over the vesting period using the fair market value of the Company’s common stock on the date of grant. As of March 31, 2013, there was $0.5 million of total unrecognized compensation cost related to Board DSUs granted to nonemployee directors. This aggregate unrecognized cost is expected to be recognized over the weighted-average period of less than 1.0 year.

17

There are a number of additional important factors that could cause actual events or our actual results to differ materially from those indicated by such forward-looking statements, including, without limitation, the factors set forth in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012, and elsewhere, and any subsequent periodic or current reports filed by us with the Securities and Exchange Commission (the “SEC”).

In addition, any forward-looking statements represent our expectations only as of the day we filed this Quarterly Report with the SEC and should not be relied upon as representing our expectations as of any subsequent date. While we may elect to update forward-looking statements at some point in the future, we specifically disclaim any obligation to do so, even if our expectations change.

Overview

We are a leading media and marketing information services firm primarily serving radio, advertisers, advertising agencies, cable and broadcast television, retailers, out-of-home media, online media, mobile media, telecommunications providers, and print media. Our main service is:

• estimating the size and composition of radio audiences in local markets and of audiences to network radio programming and commercials in the United States.

We also provide services in the following areas:

• estimating the size and composition of audiences to media other than radio, including mobile media, television viewed out-of-home, and content distributed on multiple platforms; we also analyze the behavior of smartphone and tablet users;

• providing qualitative information about consumers, including their lifestyles, shopping patterns, and use of media; and

• providing software to access and analyze media audience and marketing information data.

We have commercialized our Arbitron Portable People Meter^TM (“PPM^®”) ratings service in 48 of the largest United States radio markets. We may choose to commercialize our PPM ratings service in additional markets in the future. We refer to each of the 48 United States radio markets in which we have commercialized our PPM service as a “PPM Market” and collectively, as the “PPM Markets.”

Historically, our quantitative radio ratings services and related software have accounted for a substantial majority of our revenue. For the three-month periods ended March 31, 2013, and 2012, our quantitative radio ratings services and related software accounted for approximately 95% and 96% of our revenue, respectively. Approximately 85% of our total revenue for the three-month period ended March 31, 2013, was derived from local radio ratings services, of which approximately 65% was from our PPM Markets and 35% was from our Diary markets.

We expect for the year ending December 31, 2013, our quantitative radio ratings services and related software licensing will account for approximately 88% of our revenue. We also expect approximately 78% of our total revenue for the year ending December 31, 2013, will be derived from local radio ratings services, of which we estimate approximately 74% will be from the PPM Markets and 26% will be from the Diary markets. Quarterly fluctuations in these percentages are reflective of the seasonal delivery schedule of our quantitative radio ratings service and our Scarborough reports. For further information regarding seasonality trends, see “Seasonality.”

While we expect our quantitative radio ratings services and related software licensing will account for the majority of our revenue for the foreseeable future, we continue to seek opportunities to diversify our revenue base by, among other things, leveraging the investment we have made in our PPM ratings service and technology.

With the commercialization of our PPM ratings service complete in 48 of the largest U.S. radio markets, our current performance is impacted by our ability, and the costs required, to address a variety of challenges and opportunities in the markets and industries we serve. See “— Ratings Trends and Initiatives for our Syndicated Radio Ratings Services” below. Protecting and supporting our existing customer base, and ensuring our services are competitive from a price, quality, and service perspective are critical components to these overall goals, although there can be no guarantee we will be successful in our efforts.

Pending Merger with Nielsen

On December 17, 2012, Nielsen, a leading global provider of information and insights into what consumers watch and buy, entered into an agreement to acquire Arbitron. For additional information regarding the pending Merger, see Note 3 to the Notes to the Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

Quality Improvement Initiatives

In an effort to address the challenges of maintaining or improving response rates and sample proportionality, we established internal benchmarks we strive to achieve for both sample quality measures and have instituted a number of methodological enhancements, including cell phone household recruiting, targeted in-person recruiting, and address-based sampling. It is more expensive for us to recruit cell phone households and to conduct targeted in-person recruiting and address-based sampling. Because we intend to continue to increase the number of cell phone households in our samples and the level of address-based and targeted in-person recruiting, we expect the expenditures required to support these methods will be material. We currently anticipate the aggregate cost of cell phone household recruitment for the PPM and Diary services, and address-based and targeted in-person recruiting for the PPM service will be approximately $21.0 million in 2013, as compared to $18.0 million in 2012.

Portable People Meter Service. In operating our PPM ratings service, we have experienced and expect to continue to experience challenges, including those related to response rates and sample proportionality as described above in “— Ratings Trends and Initiatives for our Syndicated Radio Ratings Services — Challenges.” We expect to continue to implement additional measures to address these challenges. Since launching our PPM ratings service, we have implemented a number of initiatives and announced additional initiatives. We believe these steps reflect our commitment to ongoing improvement and our responsiveness to feedback from customers and governmental entities. We believe these commitments and enhancements are consistent with our efforts to continuously improve our radio ratings services and to obtain and maintain MRC accreditation. We expect these initiatives will likely continue to require expenditures that will be material in the aggregate.

Diary Service. We strive to achieve representative samples. We believe that additional expenditures will be required in the future as we continue to research and test new measures associated with improving response rates and sample proportionality as described above in “— Ratings Trends and Initiatives for our Syndicated Radio Ratings Services — Challenges.”

MRC Accreditation

On February 5, 2013, we announced that the MRC had accredited the radio average-quarter-hour monthly ratings data produced by the Portable People Meter^TM (PPM^®) ratings service in four additional markets: Chicago, San Francisco, San Diego and Charlotte-Gastonia-Rock Hill and that the MRC had also voted to continue accreditation in fourteen markets. As of the date we filed this Quarterly Report on Form 10-Q with the Securities and Exchange Commission, the quarter-hour-based radio ratings data produced by the PPM ratings service is accredited by the MRC in a total of 18 local markets: Atlanta; Baltimore; Charlotte-Gastonia-Rock Hill; Chicago; Cincinnati; Houston-Galveston; Kansas City; Los Angeles; Milwaukee-Racine; Minneapolis-St. Paul; Philadelphia; Phoenix; Riverside-San Bernardino; San Antonio; San Diego; San Francisco; St. Louis; and Tampa-St. Petersburg-Clearwater. We have applied for accreditation in all PPM Markets. We continue to seek accreditation in all unaccredited PPM Markets. For additional information regarding the status of MRC accreditation of our ratings services, see “Item 1. Business — Media Rating Council Accreditation” in our Annual Report on Form 10-K for the year ended December 31, 2012.

19

Privacy and Data Security

We are subject to U.S. and international data protection and privacy statutes, rules, and regulations, and may in the future become subject to additional such statutes, rules, and regulations. Complying with these laws may require us to make certain investments, make modifications to existing services, or prohibit us from offering certain types of services, any of which may be material and adversely impact our financial results. Failure to comply could result in civil and criminal liability, negative publicity, data being blocked from use, and liability under contracts with our customers, vendors, and partners.

Concentration of Customers

We have a limited number of key customers who license our ratings services and related software. For example, during the three-month period ended March 31, 2013, Clear Channel represented approximately 19% of our total revenue. Additionally, the amount of revenue associated with customer contracts expiring over the next two years is larger, as compared to recent historical average annual renewal levels. If one or more key customers do not renew all or part of their contracts as they expire, we could experience a significant decrease in our operating results.

Critical Accounting Policies and Estimates

Critical accounting policies and estimates are those that are both important to the presentation of our financial position or results of operations, and require our most difficult, complex or subjective judgments.

Software development costs. We capitalize software development costs with respect to significant internal use software initiatives or enhancements from the time the preliminary project stage is completed and management considers it probable the software will be used to perform the function intended, until the time the software is placed in service for its intended use. Once the software is placed in service, the capitalized costs are amortized over periods of three to five years. We perform an assessment quarterly to determine if it is probable all capitalized software will be used to perform its intended function. If an impairment exists, the software cost is written down to estimated fair value. As of March 31, 2013, and December 31, 2012, our capitalized software developed for internal use had carrying amounts of $26.8 million and $27.2 million, respectively, including $9.4 million and $9.9 million, respectively, of software related to the PPM service.

Deferred income taxes. We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year and for deferred tax assets and liabilities for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. We must make assumptions, judgments and estimates to determine the current provision for income taxes and also deferred tax assets and liabilities and any valuation allowance to be recorded against a deferred tax asset. Our assumptions, judgments, and estimates relative to the current provision for income taxes take into account current tax laws, interpretation of current tax laws and possible outcomes of current and future audits conducted by domestic and foreign tax authorities. Changes in tax law or interpretation of tax laws and the resolution of current and future tax audits could significantly impact the amounts provided for income taxes in the consolidated financial statements. Our assumptions, judgments and estimates relative to the value of a deferred tax asset take into account forecasts of the amount and nature of future taxable income. Actual operating results and the underlying amount and nature of income in future years could render current assumptions, judgments and estimates of recoverable net deferred tax assets inaccurate. We believe it is more likely than not that we will realize the benefits of these deferred tax assets. Any of the assumptions, judgments and estimates mentioned above could cause actual income tax obligations to differ from estimates, thus impacting our financial position and results of operations.

We include, in our tax calculation methodology, an assessment of the uncertainty in income taxes by establishing recognition thresholds for our tax positions. Inherent in our calculation are critical judgments by management related to the determination of the basis for our tax positions. For further information regarding our unrecognized tax benefits, see Note 9 in the Notes to Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

20

Contingent consideration. The agreement governing the 2011 acquisition of Zokem Oy, now Arbitron Mobile Oy (“Arbitron Mobile”), provides for possible additional cash payments to be made by us to the former Zokem Oy shareholders through 2015 of up to $12.0 million, contingent upon Arbitron Mobile reaching certain financial performance targets in the future. We periodically estimate the fair value of the contingent consideration and any change in fair value will be recognized in our consolidated financial results of operations. The estimate of the fair value of contingent consideration requires subjective assumptions to be made of future operating results. For further information regarding our contingent consideration, see Note 8 in the Notes to Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

(1) EBIT (earnings before interest and income taxes), EBIT Margin (EBIT divided by revenue), EBITDA (earnings before interest, income taxes, depreciation and amortization), and EBITDA Margin (EBITDA divided by revenue) are non-GAAP financial measures we believe are useful to investors in evaluating our results. See “—EBIT and EBITDA” below for further discussion of these non-GAAP financial measures.

22

Revenue. Revenue increased by 5.1% or $5.4 million for the three-month period ended March 31, 2013, as compared to the same period in 2012, due primarily to our PPM-based ratings service revenue, which increased by $3.9 million due to negotiated price increases in our PPM Markets, and a $0.6 million increase associated with our Scarborough qualitative service revenue.

Cost of Revenue. Cost of revenue increased by 4.5% or $2.2 million for the three-month period ended March 31, 2013, as compared to the same period in 2012. Cost of revenue increased primarily due to a $1.2 million increase associated with the ongoing building and support of our Arbitron Mobile service panel, and a $0.8 million increase in aggregate costs associated with address-based sampling, in-person recruiting, and cell-phone household recruiting for the three-month period ended March 31, 2013, as compared to the same period in 2012.

Selling, General, and Administrative. Selling, general, and administrative expense increased by 25.0% or $4.5 million for the three-month period ended March 31, 2013, as compared to the same period in 2012. Selling, general, and administrative costs increased primarily due to $3.2 million of consulting and legal expenses related to the pending Merger incurred during the three-month period ended March 31, 2013.

Income Tax Expense. The effective tax rate increased to 41.5% for the three-month period ended March 31, 2013, from 38.1% for the three-month period ended March 31, 2012. This increase for the three-month period ended March 31, 2013, as compared to the same period of 2012, resulted primarily from certain nondeductible transaction costs anticipated during 2013 in relation to the pending Merger.

EBIT and EBITDA. We believe presenting EBIT and EBITDA, both non-GAAP financial measures, as supplemental information helps investors, analysts and others, if they so choose, understand and evaluate our operating performance in some of the same ways we do because EBIT and EBITDA exclude certain items not directly related to our core operating performance. We reference these non-GAAP financial measures in assessing current performance and making decisions about internal budgets, resource allocation and financial goals. EBIT is calculated by deducting interest income from net income and adding back interest expense and income tax expense to net income. EBITDA is calculated by deducting interest income from net income and adding back interest expense, income tax expense, and depreciation and amortization to net income. EBIT and EBITDA margins are calculated as percentages of revenue. EBIT and EBITDA should not be considered substitutes either for net income, as indicators of our operating performance, or for cash flow, as measures of our liquidity. In addition, because EBIT and EBITDA may not be calculated identically by all companies, the presentation here may not be comparable to other similarly titled measures of other companies.

EBIT and EBITDA decreased by $0.9 million and $1.9 million, respectively, for the three-month period ended March 31, 2013, as compared to 2012, primarily due to $3.2 million of consulting and legal expenses incurred in association with the pending Merger.

We expect, based on current and anticipated levels of operating performance, our cash flow from operations, cash and cash equivalents, and availability under our Credit Facility will be sufficient to support our operations, as well as any expected costs to be incurred in association with completing the pending Merger for the next 12 to 24 months. See “— Credit Facility” below for further discussion of the relevant terms and covenants.

Cash flow from operating activities. For the three-month period ended March 31, 2013, the net cash provided by operating activities was $21.6 million, which was primarily due to $34.7 million of EBITDA, increased by $2.2 million of non-cash share-based compensation and a $2.4 million non-cash Scarborough affiliate loss.

Net cash provided by operating activities was also positively impacted by the receipt of a $1.0 million Scarborough affiliate cash distribution for the three-month period ended March 31, 2013. These positive operating cash flow items were offset by a $13.8 million decrease in payroll, bonus, and benefit accruals, which included the payment of the 2012 incentive bonus during the first quarter of 2013. Also, Scarborough royalty costs resulted in a $8.1 million negative impact to cash provided by operating activities as payments for the first quarter of 2013 exceeded royalties expensed because of the quarterly seasonality of Scarborough sales.

EBITDA is discussed and reconciled to net income in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations.”

Cash flow from investing activities. Net cash used in investing activities for the three-month periods ended March 31, 2013, and 2012, was $4.1 million and $4.9 million, respectively. This $0.8 million decrease in cash used in investing activities was primarily due to a $1.3 million decrease in internally developed and purchased software capital expenditures for the three-month period ended March 31, 2013, as compared to the same period in 2012.

Cash flow from financing activities. Net cash used in financing activities for the three-month periods ended March 31, 2013, and 2012, was $0.2 million and $18.8 million, respectively. During the three-month period ended March 31, 2013, we had no repurchases of our common stock. During the three-month period ended March 31, 2012, we repurchased $17.3 million of our common stock. In addition, there was a $1.0 million increase in proceeds from stock option exercises and stock purchase plans for the three-month period ended March 31, 2013, when there were a larger number of stock options nearing their expiration, as well as an increase in our average common stock price, as compared to the same period of 2012.

Credit Facility

On November 21, 2011, we entered into the Credit Facility, a new agreement with a consortium of lenders to provide up to $150.0 million of financing through a five-year, unsecured revolving credit facility expiring on November 21, 2016. The agreement contains an expansion feature to increase the total financing available under the Credit Facility by up to $75.0 million to an aggregate of $225.0 million. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of the lending banks, and/or in combination with one or more new lending institutions, subject to the approval of the Credit Facility’s administrative agent. Interest on borrowings under the Credit Facility is calculated based on a floating rate for a duration of up to nine months (or, with the consent of each lender, nine or 12 months), at which time the interest rate is reset based upon the LIBOR.

24

Our Credit Facility contains financial terms, covenants and operating restrictions that potentially restrict our financial flexibility. The material debt covenants under our Credit Facility include both a maximum leverage ratio and a minimum interest coverage ratio. The leverage ratio is a non-GAAP financial measure equal to the amount of our consolidated total indebtedness, as defined in our Credit Facility, divided by a contractually defined adjusted Earnings Before Interest, Taxes, Depreciation and Amortization and non-cash compensation (“Consolidated EBITDA”) for the trailing four-quarter period. The interest coverage ratio is a non-GAAP financial measure equal to Consolidated EBITDA divided by total interest expense. Both ratios are designed as measures of our ability to meet current and future debt obligations. The following table presents the actual ratios and their threshold limits as defined by the Credit Facility as of March 31, 2013:

Covenant	Threshold		Actual
Maximum leverage ratio		3.25		0.00
Minimum interest coverage ratio		3.00		221.0

As of March 31, 2013, based upon these financial covenants, there was no default or limit on our ability to borrow the unused portion of our Credit Facility.

Our Credit Facility contains customary events of default, including nonpayment and breach covenants. In the event of default, repayment of borrowings under the Credit Facility could be accelerated. Our Credit Facility also contains cross default provisions whereby a default on any material indebtedness, as defined in the Credit Facility, could result in the acceleration of our outstanding debt and the termination of any unused commitment under the Credit Facility. The agreement potentially limits, among other things, our ability to sell assets, incur additional indebtedness, and grant or incur liens on our assets. Under the terms of the Credit Facility, all of our material domestic subsidiaries, if any, must guarantee the commitment. Currently, we do not have any material domestic subsidiaries as defined under the terms of the Credit Facility. Although we do not believe the terms of our Credit Facility limit the operation of our business in any material respect, the terms of the Credit Facility may restrict or prohibit our ability to raise additional debt when needed or could prevent us from investing in other growth initiatives. We have been in compliance with the terms of the Credit Facility since the inception of the agreement. As of April 23, 2013, we had no outstanding borrowings under the Credit Facility.

Seasonality

Revenue

We recognize revenue for services over the term of license agreements as services are delivered while expenses are recognized as incurred. As of Spring 2013, we gather radio-listening data in 274 U.S. local markets, including 226 Diary markets and 48 PPM Markets.

In 2013, we expect that 12 PPM Markets will have four PPM ratings reports delivered in the third quarter and 36 PPM Markets will have four PPM ratings reports delivered in the fourth quarter. Prior to 2013, all 48 PPM Markets had four reports delivered in the fourth quarter. This change in market delivery dates for the 12 PPM Markets receiving the reports in the third quarter of 2013 are expected to cause some PPM revenue to shift from the fourth quarter to the third quarter of 2013.

All 226 Diary markets are measured at least twice per year (April-May-June for the “Spring Survey” and October-November-December for the “Fall Survey”). In addition, we measure 47 larger Diary markets an additional two times per year (January-February-March for the “Winter Survey” and July-August-September for the “Summer Survey”). We generally deliver our Diary ratings reports and recognize the related revenue in the quarter after the survey is measured. Consequently, our Diary revenue is generally higher in the first and third quarters as a result of the delivery of the Fall Survey and Spring Survey to all Diary markets compared to revenue in the second and fourth quarters, when delivery of the Winter Survey and Summer Survey, respectively, is made only to 47 larger Diary markets.

Revenue related to the sale of Scarborough services by Arbitron is recognized predominantly in the second and fourth quarters when the substantial majority of services are delivered.

As a result of the various seasonal impacts mentioned above consolidated revenue is typically highest in the fourth quarter and lowest in the second quarter of each year.

Costs and expenses

Now that all our planned PPM Markets are commercialized, and because we conduct our PPM services continuously throughout the year, we do not expect significant seasonality in PPM costs and expenses. In our Diary service, our expenses are generally higher in the second and fourth quarters as we conduct the Spring and Fall Surveys for all 226 of our Diary Markets.

Equity earnings/losses in Scarborough Research

Our affiliate, Scarborough, typically experiences losses during the first and third quarters of each year because revenue is recognized predominantly in the second and fourth quarters when the substantial majority of services are delivered. The royalties we pay Scarborough are recognized in cost of revenue and are higher during the second and fourth quarters.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our interest income and expense are sensitive to fluctuations in the general level of interest rates. As such, changes in interest rates affect the interest earned on the Company’s cash and cash equivalents and other highly liquid investments, as well as the value of those investments.

In November 2011, we entered into our Credit Facility with a consortium of lenders to provide us up to $150.0 million of financing. Interest on borrowings under the Credit Facility is calculated based on a floating rate for a duration of up to nine months, at which time the interest rate is reset based upon the LIBOR. As of March 31, 2013, we had no outstanding borrowings under the Credit Facility. Therefore, a hypothetical market interest rate change of 1% would have zero impact on our results of operations over a 12-month period. A hypothetical market interest rate change of 1% would have no impact on either the carrying amount or the fair value of the Credit Facility. We do not use derivatives for speculative or trading purposes.

Foreign Currency Risk

We are exposed to the translation of foreign currency earnings to the U.S. dollar. Our principal exposures are to the euro via our Finnish subsidiary and the Indian rupee via our Indian subsidiary. If we expand our foreign operations in both Finland and India, our exposure to foreign currency exchange rate trends could increase, resulting in higher or lower translation impacts to our financial results and position.

As of March 31, 2013, we had $11.4 million in recorded intercompany balances on our Finnish and Indian subsidiary balance sheets, which are impacted by fluctuations in currency exchange rates. As the exchange rates increase or decrease, our intercompany balances will be exposed to translation adjustment charges and/or credits, which will be recognized in our financial results.

Financial statements of foreign subsidiaries are translated into U.S. dollars at current rates at the end of the period except that revenue and expenses are translated at average current exchange rates during each reporting period. The translation adjustments are recorded in accumulated other comprehensive loss on our consolidated balance sheet until the net investment in such foreign subsidiaries is liquidated. As of March 31, 2013, the cumulative net currency translation adjustment recorded on our balance sheet reduced our shareholders’ equity by $2.2 million.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s President and Chief Executive Officer and the Company’s Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the most recently completed fiscal quarter. Based upon that evaluation, the Company’s President and Chief Executive Officer and the Company’s Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this Report.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarterly period ended March 31, 2013, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are involved, from time to time, in litigation and proceedings, including with governmental authorities, arising out of the ordinary course of business. Legal costs for services rendered in the course of these proceedings are charged to expense as they are incurred.

On or about June 13, 2008, a purported stockholder derivative lawsuit, Pace v. Morris, et al., was filed against Arbitron, as a nominal defendant, each of our directors, and certain of our current and former executive officers in the Supreme Court of the State of New York for New York County. The derivative lawsuit is based on essentially the same substantive allegations as the securities class action lawsuit. The derivative lawsuit asserts claims against the defendants for misappropriation of information, breach of fiduciary duty, abuse of control, and unjust enrichment. On July 28, 2011 the derivative plaintiff filed an amended complaint that reiterated, in large part, the claims of the original complaint filed in 2008. The amended complaint also added claims for breach of fiduciary duty related to the retirement of Mr. Morris in 2009 and the resignation of Mr. Skarzynski in 2010. The derivative plaintiff sought equitable and/or injunctive relief, restitution and disgorgement of profits, plus attorneys’ fees and costs, among other remedies. On January 18, 2013, the derivative plaintiff filed a Stipulation of Discontinuance, which terminated this case.

On January 24, 2013, a putative class action lawsuit was filed in the Court of Chancery of the State of Delaware regarding the proposed Merger. The complaint (“Complaint”) was purportedly filed on behalf of the public shareholders of the Company, and names as defendants, the Company, each of the Company’s directors, Merger Sub, and Nielsen. The Complaint alleged, among other things, that the Company’s directors breached their fiduciary duties by failing to maximize shareholder value in a proposed sale of the Company. The Complaint further alleged that the Company’s preliminary proxy statement failed to provide material information and provided materially misleading information relating to the Merger and that the Company and Nielsen aided and abetted the alleged breaches by the Company’s directors. The plaintiff sought, among other things, class action status, an injunction preventing the completion of the Merger (or, if the Merger were completed, rescinding the Merger or awarding rescissory damages), and the payment of attorneys’ fees and expenses.

On March 7, 2013, the parties to the litigation entered into a memorandum of understanding (the “MOU”) providing for a settlement, subject to court approval, of the action on behalf of the named plaintiff and a class of the shareholders affected by the transaction (the “Settlement”). The Settlement will be submitted to the Court of Chancery for approval. If approved by the Court of Chancery, the Settlement will resolve all of the allegations and claims asserted by the plaintiff and the class against all defendants in connection with the Merger and will further provide for the release and settlement by the class of the Company’s shareholders of all claims against all of the defendants and their affiliates in connection with the Merger. As part of the MOU, all of the defendants denied all allegations of wrongdoing and denied that the disclosures made by the Company in the Company’s preliminary proxy statement on Schedule 14A as filed on January 18, 2013 were inadequate, but the Company agreed to provide certain additional disclosures in its definitive proxy statement relating to the Merger and to waive the “no-ask, no-waiver” provision in the existing confidentiality agreements. The Settlement will not affect the form or amount of consideration to be paid to the Company’s shareholders in the Merger.

We are involved from time to time in a number of judicial and administrative proceedings considered ordinary with respect to the nature of our current and past operations, including employment-related disputes, contract disputes, government proceedings, customer disputes, and tort claims. In some proceedings, the claimant seeks damages as well as other relief, which, if granted, would require substantial expenditures on our part. Some of these matters raise difficult and complex factual and legal issues, and are subject to many uncertainties, including, but not limited to, the facts and circumstances of each particular action, and the jurisdiction, forum and law under which each action is pending. Because of this complexity, final disposition of some of these proceedings may not occur for several years. As such, we are not always able to estimate the amount of our possible future liabilities. There can be no certainty that we will not ultimately incur charges in excess of present or future established accruals or insurance coverage. Although occasional adverse decisions (or settlements) may occur, we believe that the likelihood that final disposition of these proceedings will, considering the merits of the claims, have a material adverse impact on our financial position or results of operations is remote.
