ARBITRON INC.

Notes to Consolidated Financial Statements

September 30, 2011

(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 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 U.S. generally accepted accounting principles 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, 2010 was audited as of that date, but all of the information and notes as of December 31, 2010 required by U.S. generally accepted accounting principles 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, 2010.

Consolidation

The consolidated financial statements of the Company for the nine-month period ended September 30, 2011, 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 have been eliminated in consolidation. Certain amounts in the consolidated financial statements for prior periods have been reclassified to conform to the current period’s presentation.

2. New Accounting Pronouncements

Testing Goodwill for Impairment. In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2011-08, Intangibles—Goodwill and Other (Topic 350)—Testing Goodwill for Impairment (“ASU 2011-08”), to allow entities to use a qualitative approach to test goodwill for impairment. ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. ASU 2011-08 is effective for the Company for interim and annual periods ended during 2012, with earlier application permitted. The Company does not expect its pending adoption of this guidance to have a material impact to the Company’s consolidated financial statements.

Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements. In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820)—Fair Value Measurement (“ASU 2011-04”), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. ASU 2011-04 is effective for the Company for interim and annual periods ended during 2012 and should be applied prospectively. The Company is currently evaluating the impact of its pending adoption of ASU 2011-04 on its consolidated financial statements.

8

Multiple-Deliverable Revenue Recognition. In October 2009, the FASB issued Accounting Standards Update No. 2009-13 Revenue Recognition (Topic 605) — Multiple-Deliverable Revenue Arrangements a consensus of the FASB Emerging Issues Task Force (“ASU 2009-13”). This requires companies to allocate revenue in multiple-element arrangements based on an element’s estimated selling price if vendor-specific or other third party evidence of value is not available. ASU 2009-13 is to be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, with earlier application permitted. There was no impact to the Company’s consolidated financial statements related to the adoption of this guidance.

3. Debt

The Company has an agreement with a consortium of lenders to provide up to $150.0 million of financing to the Company through an unsecured revolving credit facility (the “Credit Facility”), expiring on December 20, 2011. The agreement contains an expansion feature for the Company to increase the total financing available under the Credit Facility by up to $50.0 million for an aggregate of up to $200.0 million in financing. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of the lenders, and/or in combination with one or more new lending institutions, subject to the approval of the Credit Facility’s administrative agent.

The Company expects to renew or replace the Credit Facility prior to its expiration. As of September 30, 2011, there were no outstanding borrowings under the Credit Facility. As of December 31, 2010, the outstanding borrowings balance under the Credit Facility was $53.0 million.

Interest paid during each of the nine-month periods ended September 30, 2011, and 2010, was $0.3 million and $0.7 million, respectively.

4. Stockholders’ Equity

Changes in stockholders’ equity for the nine-month period ended September 30, 2011, 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, 2010		27,055	$	16,169	$	(2,642	)	$	74,184		$	(10,060	)	$	77,651

A quarterly cash dividend of $0.10 per common share was paid to stockholders on October 3, 2011.

5. Net Income per Weighted-Average Common Share

The computations of basic and diluted net income per weighted-average common share for the three and nine-month periods ended September 30, 2011, and 2010, 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 that the proceeds from the exercise of all stock options are used to repurchase the Company’s common stock at the average market price for the period. As of September 30, 2011, and 2010, there were stock options to purchase 2,094,214 and 2,248,119 shares, respectively, of the Company’s common stock outstanding, of which stock options to purchase 1,102,228 and 1,530,410 shares of the Company’s common stock, respectively, were excluded from the computation of diluted net income per weighted-average common share for the quarters ended September 30, 2011, and 2010, 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. Comprehensive Income and Accumulated Other Comprehensive Loss

The Company’s comprehensive income is comprised of net income, changes in foreign currency translation adjustments, and changes in retirement liabilities, net of tax. The components of comprehensive income were as follows (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2011			2010		2011			2010
Net income	$	15,351		$	11,328	$	39,182		$	28,875

7. Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets as of September 30, 2011, and December 31, 2010, consist of the following (in thousands):

Prepaid income taxes		1,787		5,518
Other		2,964		2,772
Prepaid expenses and other current assets	$	8,670	$	11,332

During 2008, the Company became involved in two securities-law civil actions and a governmental interaction primarily related to the commercialization of our PPM service. The management of the Company believes a portion of these legal fees and costs are covered by the Company’s Directors and Officers insurance policy and therefore has recognized an insurance recovery receivable. From 2008 until September 30, 2011, the Company had incurred approximately $11.0 million in legal fees and costs in defense of its positions related thereto, and as of September 30, 2011, the Company had received $7.1 million in insurance reimbursements related to these legal actions. From 2008 until December 31, 2010, the Company had incurred approximately $9.7 million in legal fees and costs in defense of its positions related thereto, and as of December 30, 2010, the Company had received $5.9 million in insurance reimbursements.

For the nine-month periods ended September 30, 2011, and 2010, the Company incurred approximately $1.3 million, and $0.3 million, respectively, in related legal fees, which were recognized as increases to selling, general, and administrative expense. These legal fees were offset by $1.4 million and $0.4 million in anticipated insurance recoveries, which were recognized as reductions to selling, general and administrative expense during the nine-month periods ended September 30, 2011, and 2010, respectively.

8. Equity and Other Investments

9. Acquisitions

Zokem Oy. On July 28, 2011, a wholly-owned subsidiary of the Company acquired Zokem Oy, a Finland-based mobile audience measurement and analytics firm now known as Arbitron Mobile. The purchase price was $10.6 million in cash plus a contingent consideration arrangement with an estimated fair value of approximately $0.9 million. The agreement provides for possible additional cash payments to be made through 2015 of up to $12.0 million, which are contingent upon Zokem reaching certain financial performance targets in the future. The $0.9 million fair value estimate was determined by applying the income approach methodology. The key assumptions used in the fair value valuation include a probability-weighted range of performance targets for the 4–year measurement period of 2012 through 2015 and an adjusted discount rate. The Company will periodically reassess the fair value of the contingent consideration.

The following table shows the preliminary assets and liabilities acquired (in thousands):

As of September 30, 2011, the purchase price allocation and related goodwill estimate are preliminary amounts that will be adjusted in the future for certain working capital and tax-related adjustments. The other intangible assets are being amortized over a weighted average life of 5.3 years. The amount of acquisition-related costs incurred and charged to selling, general and administrative expense during the nine-month period ended September 30, 2011, was $0.6 million.

Integrated Media Measurement, Inc. On June 15, 2010, a wholly-owned subsidiary of the Company purchased the technology portfolio, trade name, and equipment of Integrated Media Measurement, Inc. The Company paid $2.5 million for these assets, which included $1.8 million of other intangible assets, $0.3 million of computer equipment, and $0.4 million of goodwill. The other intangible assets are being amortized over 5.0 years.

Digimarc Corporation. On March 23, 2010, the Company entered into a licensing arrangement with Digimarc Corporation (“Digimarc”) to receive a non-exclusive, worldwide and irrevocable license to a substantial portion of Digimarc’s domestic and international patent portfolio. The Company paid $4.5 million for this other intangible asset, which is being amortized over 7.0 years.

Future amortization expense of the Company’s $12.2 million of other intangible assets recorded on the consolidated balance sheet as of September 30, 2011, is estimated to be as follows:

	Amount
3-Month Period Ended December 31, 2011	$	634
2012		2,537
2013		2,487
2014		2,419
2015		2,186
2016		1,466
Thereafter		494
Total	$	12,223

10. Contingencies

The Company is involved in a number of governmental interactions primarily related to the commercialization of our PPM service. A contingent loss in the amount of $0.4 million and $0.5 million for these claims was recorded in accrued expenses and other current liabilities on the Company’s consolidated balance sheets as of September 30, 2011, and December 31, 2010, respectively.

11. 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 also subsidizes healthcare benefits for eligible retired employees who participate in the pension plan and were hired before January 1, 1992. The Company had one nonqualified, unfunded supplemental retirement plan during the nine-month period ended September 30, 2011. The Company sponsored two supplemental retirement plans during the nine-month period ended September 30, 2010, prior to the termination of one of the supplemental plans in the third quarter of 2010.

14

The components of periodic benefit costs for the defined-benefit pension, postretirement healthcare and supplemental retirement plan(s) were as follows (in thousands):

	Defined-Benefit Pension Plan Three Months Ended September 30,						Postretirement Healthcare Plan Three Months Ended September 30,				Supplemental Retirement Plan(s) Three Months Ended September 30,
	2011			2010			2011		2010		2011		2010
Service cost	$	193		$	183		$	9	$	9	$	5	$	4
Interest cost		454			470			20		22		40		42
Expected return on plan assets		(512	)		(520	)		—		—		—		—
Amortization of net loss		343			263			7		9		38		38

Service cost	$	580		$	548		$	28	$	28	$	15	$	12
Interest cost		1,364			1,412			61		67		120		151
Expected return on plan assets		(1,538	)		(1,588	)		—		—		—		—
Amortization of net loss		1,028			789			21		27		114		110
Net periodic benefit cost	$	1,434		$	1,161		$	110	$	122	$	249	$	273
Settlement and curtailment loss	$	—		$	—		$	—	$	—	$	—	$	1,222

During the nine-month period ended September 30, 2010, the Company recognized a $1.2 million settlement and curtailment loss, primarily as a result of a lump sum distribution paid to a supplemental retirement plan participant which exceeded the service and interest components incurred for that plan. No settlement and curtailment charge was incurred during the nine-month period ended September 30, 2011.

The Company estimates it will contribute $2.2 million to its defined benefit plans during 2011.

12. Taxes

The effective tax rate increased to 39.5% for the nine months ended September 30, 2011, from 37.8% for the nine months ended September 30, 2010. The increase includes the estimated effect of certain Arbitron Mobile operating losses, which are subject to limitation, and may not be available to offset future taxable income.

During 2011, the Company’s net unrecognized tax benefits for certain tax contingencies decreased from $1.9 million as of December 31, 2010, to $1.1 million as of September 30, 2011. The decrease is attributable to the settlement of a state audit and expiration of statutes of limitations in various jurisdictions. 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 nine-months ended September 30, 2011 and 2010, were $21.1 million and $19.4 million, respectively.

13. Share-Based Compensation

The following table sets forth information with regard to the income statement recognition of share-based compensation (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010
Cost of revenue	$	200	$	115	$	442	$	294
Selling, general and administrative		1,734		1,398		5,164		4,206
Research and development		95		96		254		210
Share-based compensation	$	2,029	$	1,609	$	5,860	$	4,710

No share-based compensation cost was capitalized during the nine-month periods ended September 30, 2011, and 2010.

Stock Options

Stock options awarded to employees under the 2001 Stock Incentive Plan and the 2008 Equity Compensation Plan (referred to herein collectively as the “SIPs”) generally vest annually over a three-year period, have a 10-year term and have an exercise price of not less than the fair market value of the Company’s common stock at the date of grant. For stock options granted prior to 2010, the Company’s stock option agreements generally provide for accelerated vesting if there is a change in control of the Company. Effective for stock options granted in 2010 and after, the Company’s stock option agreements provide for accelerated vesting if (i) there is a change in control of the Company and (ii) the participant’s employment terminates during the 24-month period following the effective date of the change in control for one of the reasons specified in the stock option agreement.

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. The Company uses historical data to estimate future option exercises and employee terminations in order to determine the expected term of the stock option, where the expected term of stock option granted represents the period of time that such stock option is expected to be outstanding. Identified groups of option holders with similar historical exercise behavior are considered separately for valuation purposes. The expected term of stock options can vary for groups of option holders exhibiting different behavior. The fair value of each stock option granted to employees and nonemployee directors during the nine-month periods ended September 30, 2011, and 2010, was estimated on the date of grant using a Black-Scholes stock option valuation model, which uses a risk-free interest rate and measure of volatility, among other things, to estimate fair value. The risk-free interest rate for periods within the contractual life of the stock option is based on the U.S. Treasury strip bond yield curve in effect at the time of grant. Expected volatilities are based on the historical volatility of the Company’s common stock.

For the three-month period ended September 30, 2011, the number of stock options granted was 81,001 and the weighted-average exercise price for those stock options granted was $34.83. For the three-month period ended September 30, 2010, no stock options were granted.

For the nine-month periods ended September 30, 2011 and 2010, the number of stock options granted was 154,226 and 288,544, respectively, and the weighted-average exercise price for those stock options granted was $39.21 and $22.84, respectively.

16

As of September 30, 2011, there was $3.0 million in total unrecognized compensation cost related to stock options granted under the SIPs. This aggregate unrecognized cost is expected to be recognized over a weighted-average remaining period of 2.0 years. The weighted-average exercise price and weighted-average remaining contractual term for outstanding stock options as of September 30, 2011, were $33.11 and 5.88 years, respectively, and as of September 30, 2010, $31.78 and 6.21 years, respectively.

Service and Performance Award Units

Service award units. During the nine-month period ended September 30, 2011, the Company granted service award shares under the SIPs. These service award units (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) vest in four equal annual installments beginning on the first anniversary date of the grant, and (iii) for any unvested units, expire without vesting if the employee is no longer employed by the Company. For those service award units granted prior to 2010, the service award units generally provide for accelerated vesting if there is a change in control of the Company. Effective for service award units granted in 2010 and after, the service award units provide for accelerated vesting if (i) there is a change in control of the Company and (ii) the participant’s employment terminates during the 24-month period following the effective date of the change in control for one of the reasons specified in the restricted stock unit agreement.

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 September 30, 2011, there was $2.4 million of total unrecognized compensation cost related to service award units granted under the SIPs. This aggregate unrecognized cost for service award units is expected to be recognized over a weighted-average period of 2.09 years.

Additional information for the three-and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010
Number of service award shares granted during the period		—		—		18,434		—
Weighted average grant-date fair value per share		—		—	$	42.72		—
Fair value of service award shares vested during the period	$	322	$	248	$	2,536	$	2,438

Performance award units. During the nine-month periods ended September 30, 2011 and 2010, the Company granted performance award units under the SIPs. 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 expire without vesting if the Company’s return on invested capital (“ROIC”) for the annual performance period does not exceed 12 percent, which is an approximation of the Company’s weighted average cost of capital, (iii) will, if the Company’s ROIC exceeds 12 percent, vest in four equal annual installments beginning on the first anniversary date of the grant, and (iv) for any unvested units, expire without vesting if the recipient is no longer employed by the Company. The Company’s performance award units provide for accelerated vesting if (i) there is a change in control of the Company and (ii) the recipient’s employment terminates during the 24-month period following the effective date of the change in control for one of the reasons specified in the performance-based restricted stock unit agreement.

Compensation expense for performance award units is recognized using the fair market value of the Company’s common stock on the date of grant and on an accelerated basis. The Company recognizes expense for these performance award units under the assumption that the performance ROIC target will be achieved. If it appears such performance ROIC target will not be met, the Company will stop recognizing any further compensation cost and any previously recognized compensation cost would be reversed. As of September 30, 2011, there was $2.4 million of total unrecognized compensation cost related to performance award units granted under the SIPs. This aggregate unrecognized cost is expected to be recognized over a weighted-average period of 3.26 years.

Fair value of performance award shares vested during the period		—		—	$	804		—

Deferred Stock Units

Service award grant to CEO. During the nine-month periods ended September 30, 2011 and 2010, the Company granted service-based deferred stock unit awards (“Service DSUs”) under the SIPs to its CEO. Service DSUs are issued 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. The Service DSUs, if vested, will be convertible into shares of the Company’s common stock following the holder’s termination of employment. The Service DSUs provide for accelerated vesting upon termination without cause or the CEO’s retirement as defined in his employment agreement. No Service DSUs were converted into shares of the Company’s common stock during the nine-month periods ended September 30, 2011, and 2010.

Compensation expense for Service 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 September 30, 2011, there was $0.2 million of total unrecognized compensation cost related to Service DSUs. This aggregate unrecognized cost is expected to be recognized over the weighted-average period of 0.28 years.

Additional information for the three- and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,
Service DSUs Awarded to CEO	2011		2010		2011		2010
Number of shares granted during the period		—		—		900		60,144
Weighted-average grant date fair value per share		—		—	$	44.44	$	24.94
Fair value of shares vested during the period		—		—	$	704		—

Performance award grant to CEO. During the nine-month periods ended September 30, 2011 and 2010, the Company granted performance-based deferred stock unit awards (“Performance DSUs”) under the SIPs to its CEO. These Performance DSUs (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) will expire without vesting if the Company’s return on invested capital (“ROIC”) for the annual

18

performance period does not exceed 12 percent, which is an approximation of the Company’s weighted average cost of capital, (iii) will, if the Company’s ROIC exceeds 12 percent, vest in four equal annual installments beginning on the first anniversary date of the grant, and (iv) provide for accelerated vesting upon termination without cause or the CEO’s retirement as defined in his employment agreement. These Performance DSUs, if vested, will be convertible into shares of the Company’s common stock, subsequent to termination of employment.

Compensation expense for Performance DSUs is recognized using the fair market value of the Company’s common stock on the date of grant and on an accelerated basis. The Company recognizes expense for these Performance DSUs under the assumption that the performance target will be achieved. If it appears such performance target will not be met, the Company will stop recognizing any further compensation cost and any previously recognized compensation cost would be reversed. As of September 30, 2011, there was $0.7 million of total unrecognized compensation cost related to Performance DSUs. This aggregate unrecognized cost is expected to be recognized over the weighted-average period of 1.20 years.

Additional information for the three- and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,
Performance DSUs Awarded to CEO	2011		2010		2011		2010
Number of shares granted during the period		—		—		24,122		23,004
Weighted-average grant date fair value per share		—		—	$	44.44	$	22.17
Fair value of shares vested during the period		—		—	$	227		—

Awards for service on Board of Directors (“Board”). The Company issues deferred stock units to its Board of Directors (“Board DSUs”) under the SIPs. 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. Annual grants of Board DSUs vest annually in three equal installments over a three-year period.

In addition to receiving Board DSU grants annually, the Board members have the right to elect to receive all or a portion of their retainer and meeting attendance fees as cash and/or Board DSUs, which vest immediately. Board DSUs are only granted to nonemployee Directors.

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 September 30, 2011, there was $1.4 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 2.30 years.

14. Concentration Risk

Arbitron is an international media and marketing information services firm primarily serving radio, advertising agencies, cable and broadcast television, advertisers, retailers, out-of-home media, online media print media, and mobile media.

The Company’s quantitative radio audience ratings service and related software licensing revenue accounted for the following percentages, in the aggregate, of total Company revenue:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2011			2010			2011			2010
Quantitative radio audience ratings service and related software licensing revenue		95	%		95	%		91	%		91	%

The Company had one customer that individually represented approximately 20% of its annual revenue for the year ended December 31, 2010. The Company had two customers that individually represented approximately 22% and 14% of its total accounts receivable as of September 30, 2011, and two customers that individually represented approximately 24% and 11% of its total accounts receivable as of December 31, 2010. The Company has historically experienced a high level of contract renewals.

15. Financial Instruments

The fair values of accounts receivable and accounts payable approximate their carrying values due to their short-term nature. The Company accounts for its $5.2 million investment in TRA’s preferred stock using the cost method of accounting. TRA is closely held and there is not an efficient market in which buyers and sellers determine the fair value of these shares. The Company periodically assesses the fair value of its investment in TRA through comparative analysis and analysis of TRA’s actual and projected financial results. As of September 30, 2011, the Company believes that the fair value of the TRA investment approximates the carrying value of $5.2 million. In the event the fair value of the investment in TRA were to fall below its carrying value in the future, the Company would be required to recognize an impairment loss.

Due to the floating rate nature of the Company’s revolving obligation under its Credit Facility, the carrying amount of $53.0 million in outstanding borrowings as of December 31, 2010, approximates its fair value.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our consolidated financial statements and the notes thereto in this Quarterly Report on Form 10-Q.

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. The statements regarding Arbitron Inc. and its subsidiaries (“we,” “our,” “Arbitron,” or the “Company”) in this document that are not historical in nature, particularly those that utilize terminology such as “may,” “will,” “should,” “likely,” “expects,” “intends,” “anticipates,” “estimates,” “believes,” “plans,” or comparable terminology, are forward-looking statements based on current expectations about future events, which we have derived from information currently available to us. These forward-looking statements involve known and unknown risks and uncertainties that may cause our actual results to differ materially from results implied by such forward-looking statements. These risks and uncertainties include, in no particular order, whether we will be able to:

• successfully maintain and promote industry usage of our services, a critical mass of broadcaster encoding, and the proper understanding of our audience ratings services and methodology in light of governmental actions, including investigation, regulation, legislation or litigation, customer or industry group activism, or adverse community or public relations efforts;

• successfully obtain and/or maintain Media Rating Council, Inc. (“MRC”) accreditation for our audience ratings services;

• successfully launch and maintain our cross-platform initiatives;

• support our current and future services by designing, recruiting and maintaining research samples that appropriately balance quality, size and operational cost;

• successfully develop, implement and fund initiatives designed to increase sample quality;

• successfully manage costs associated with cell phone household recruitment and targeted in-person recruitment;

• successfully manage the impact on our business of the economic environment generally, and in the advertising market, in particular, including, without limitation, the insolvency of any of our customers or the impact of a downturn on our customers’ ability to fulfill their payment obligations to us;

• successfully integrate acquired operations, including differing levels of management and internal control effectiveness at the acquired entity;

• compete with companies that may have financial, marketing, sales, technical or other advantages over us;

• effectively respond to rapidly changing technologies by creating proprietary systems to support our research initiatives and by developing new services that meet marketplace demands in a timely manner;

• successfully execute our business strategies, including evaluating and, where appropriate, entering into potential acquisition, joint-venture or other material third-party agreements;

• manage and process the information we collect in compliance with data protection and privacy requirements;

21

• successfully develop and implement technology solutions to identify and report consumer use of new and existing forms of media content and delivery, and advertising in an increasingly competitive environment; and

• renew contracts with key customers.

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, 2010, 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 an international media and marketing information services firm primarily serving radio, advertising agencies, cable and broadcast television, advertisers, retailers, out-of-home media, online media, print media, and mobile media. We currently provide four main services:

• measuring and estimating radio audiences in local markets in the United States;

• measuring and estimating radio audiences of network radio programs and commercials;

• providing software used for accessing and analyzing our media audience and marketing information data; and

• providing consumer, shopping, and media usage information services.

Historically, our quantitative radio ratings services and related software have accounted for a substantial majority of our revenue. For each of the nine-month periods ended September 30, 2011, and 2010, our quantitative radio ratings services and related software accounted for approximately 91 percent of our revenue. We expect that for the year ending December 31, 2011, our quantitative radio ratings services and related software licensing will account for approximately 89 percent of our revenue.

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 that our quantitative radio ratings services and related software licensing will continue to account for the majority of our revenue for the foreseeable future, we are actively seeking opportunities to diversify our revenue base by, among other things, leveraging the investment we have made in our Portable People Meter^TM (“PPM^TM”) Platform, (which we define as our PPM technology and our PPM panel combined), and exploring applications of the PPM Platform to both enhance and extend beyond our domestic radio ratings business.

As of December 31, 2010, we completed the commercialization of our PPM radio ratings service in 48 of the largest United States radio markets (“PPM Markets”). We believe those broadcasters with whom we have entered into multi-year PPM agreements account for most of the total radio advertising dollars in the PPM Markets. These agreements provide for a higher fee for PPM-based ratings than we charged for our Diary-based ratings. As a result, absent new initiatives, we expect the percentage of our revenues derived from our quantitative radio ratings services and related software to increase as a result of the commercialization of the PPM service in the PPM Markets.

22

We expect growth in revenue for 2011 due to the full year impact of revenue recognized for the PPM Markets commercialized in 2010 in addition to price increases related to pre-2010 commercialized PPM Markets and annual escalators in our Diary markets. However, we do not expect the full revenue impact of the launch of each PPM Market to occur within the first year after commercialization because our customer contracts are typically structured to phase in higher PPM service rates over a period of time.

As we commercialized the PPM ratings service, we incurred expenses to build the PPM panel in each PPM Market in the months before commercializing the service in that market. These costs were incremental to the costs associated with our Diary-based ratings service during those periods. With the commercialization of our PPM ratings service complete, our future performance will be impacted by our ability to address a variety of challenges and opportunities in the markets and industries we serve, including our ability to continue to maintain and improve the quality of our PPM ratings service, and manage increased costs for data collection, arising among other ways, from targeted in-person recruiting and increased numbers of cell phone households, which are more expensive for us to recruit than households with landline phones.

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.

Ratings Trends and Initiatives

Challenges in Our Radio Audience Ratings Service

We face a number of challenges in our radio audience ratings services. Response rates are one measure of our effectiveness in obtaining consent from persons to participate in our surveys and panels. Overall response rates for survey research, in general, have declined over the past several decades, and it has become increasingly difficult and more costly for us to obtain consent from persons to participate in our surveys and panels. We have been adversely impacted by these industry trends. Another measure often employed by users of our data to assess quality in our ratings is sample proportionality, which refers to how well the distribution of the sample for any individual survey compares to the distribution of the population in the local market. We strive to achieve a level of both response rates and sample proportionality in our surveys sufficient to maintain confidence in our ratings and acceptance by the industry, and to support accreditation by the MRC.

If response rates continue to decline or we are unable to maintain sample proportionality in our surveys or the costs of recruitment initiatives significantly increase, our radio audience ratings business could be adversely affected. In an effort to address these challenges, we established internal benchmarks we strive to achieve for response rates and sample proportionality and have instituted a number of methodological enhancements, including cell phone household and targeted in-person recruiting. It is more expensive for us to recruit cell phone households and to conduct targeted in-person recruiting. Because we intend to continue to increase both the number of cell phone households in our samples and the level of targeted in-person recruiting, we expect the expenditures required to support these methods will be material. We currently anticipate that the aggregate cost of cell phone household recruitment for the PPM and Diary services and targeted in-person recruitment for the PPM service will be approximately $16.0 million in 2011, as compared to $15.0 million in 2010.

MRC Accreditation

In March 2011, we announced the MRC had accredited the monthly average-quarter-hour radio ratings data produced by our PPM service in 11 additional PPM Markets: Atlanta; Cincinnati; Cleveland; Kansas City; Milwaukee-Racine; Philadelphia; Phoenix; Portland, OR; Salt Lake City-Ogden-Provo; St. Louis, and Tampa-St. Petersburg-Clearwater. These 11 markets joined Houston-Galveston; Minneapolis-St. Paul and Riverside-San Bernardino as accredited markets for our PPM service, bringing the total number of MRC-accredited PPM Markets to 14. The MRC has denied accreditation in our other 34 PPM Markets based on findings of audits it conducted in 2010. We continue to seek accreditation in all of our unaccredited PPM Markets. All 48 PPM Markets have been or will be audited again in 2011.

23

In April 2011, we also announced the MRC had accredited our TAPSCAN Web software, a Web-based sales proposal and analysis software system for radio. Reports created using the software and MRC accredited data will now indicate the software is accredited by the MRC. However, reports created using data from the 34 unaccredited PPM markets will not be MRC-accredited.

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, 2010.

Quality Improvement Initiatives.

Portable People Meter Service. In operating our PPM ratings service, we experienced and expect to continue to experience challenges, including those related to response rates and sample proportionality as described above in “Challenges in Our Radio Audience Ratings Services.” 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, which we refer to, collectively, as our continuous improvement initiatives, are consistent with our ongoing efforts to obtain and maintain MRC accreditation and to continuously improve our radio ratings services. We expect our continuous improvement initiatives will require expenditures which 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 to research and test new measures associated with improving response rates and sample proportionality as described above in “Challenges in Our Radio Audience Ratings Services.” We continue to research and test new measures to address these sample quality challenges.

Privacy and Data Security

We are currently 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. These statutes, rules, and regulations may affect our collection, use, storage, and transfer of personally identifiable information. 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. Failing to comply could result in civil and criminal liability, negative publicity, data being blocked from use, and liability under contracts with our customers and partners.

Zokem Oy

On July 28, 2011, a wholly-owned subsidiary of the Company acquired Zokem Oy, a Finland-based mobile audience measurement and analytics firm, which is now known as Arbitron Mobile. The purchase price for the acquisition was approximately $10.6 million in cash plus a contingent consideration arrangement which we currently estimate has a fair value of approximately $0.9 million. The arrangement provides for possible additional cash payments to be made through 2015 of up to $12.0 million, contingent upon Arbitron Mobile reaching certain financial performance targets in the future.

24

Credit Facility

Our revolving credit facility agreement (“Credit Facility”) is scheduled to expire on December 20, 2011. We expect to renew or replace our Credit Facility prior to its expiration. See Liquidity and Capital Resources—Credit Facility below for further information regarding the terms of our Credit Facility.

General Economic Conditions

Many of our customers derive most of their revenue from transactions involving the sale or purchase of advertising. During recent challenging economic times, advertisers have reduced advertising expenditures, impacting advertising agencies and media. As a result, advertising agencies and media companies have been and may continue to be less likely to purchase our services, which has and could continue to adversely impact our business, financial position, and operating results. If the recovery from the recent economic downturn slows or if the economy experiences another downturn in the foreseeable future, it may also lead to an increase of incidences of customers’ inability to pay their accounts, an increase in our provision for doubtful accounts, and a further increase in collection cycles for accounts receivable or insolvency of our customers.

We depend on a limited number of key customers for our ratings services and related software. For example, in 2010, Clear Channel represented approximately 20 percent of our total revenue. Additionally, although fewer customer contracts expire in 2011 as compared to historical standards, 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 September 30, 2011, and December 31, 2010, our capitalized software developed for internal use had carrying amounts of $29.1 million and $24.4 million, respectively, including $11.0 million and $12.4 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.

25

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 12 in the Notes to Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

Insurance Receivables. During 2008, we became involved in two securities-law civil actions and a governmental interaction primarily related to the commercialization of our PPM service. Since 2008, we have incurred a combined total of $11.0 million in legal fees and expenses in connection with these matters. As of September 30, 2011, an aggregate of $7.1 million in insurance reimbursements related to these legal actions has been received. As of September 30, 2011, and December 31, 2010, our insurance claims receivable related to these legal actions was $0.8 million and $0.6 million, respectively, and these amounts are included in our prepaid expenses and other current assets on our balance sheet. See Note 7 in our Notes to Consolidated Financial Statements for additional information concerning our insurance recovery receivables.

Cost Method Investment. We account for our $5.2 million investment in TRA’s preferred stock using the cost method of accounting. TRA is closely held and there is not an efficient market in which buyers and sellers determine the fair value of these securities. We periodically assess the fair value of our investment in TRA through comparative analysis and analysis of TRA’s actual and projected financial results. Our assessment of the fair value of TRA requires the use of estimates and judgment. TRA is currently engaged in raising additional capital, which it has indicated to us it expects to complete in the fourth quarter of 2011. In the event the fair value of our investment in TRA were to fall below its carrying value, we would be required to recognize an impairment loss.

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

Revenue. Revenue increased by 6.1% or $6.1 million for the three-month period ended September 30, 2011, as compared to the same period in 2010. PPM-based ratings service revenue increased by $13.1 million primarily due to the impact of the five PPM Markets commercialized during the last quarter of 2010, as well as price escalators in all PPM commercialized markets. This increase in PPM revenue was partially offset by a $7.2 million decrease in revenue related to the transition from our Diary-based ratings service.

Cost of Revenue. Cost of revenue decreased by 2.0% or $1.0 million for the three-month period ended September 30, 2011, as compared to the same period in 2010. Cost of revenue decreased primarily due to $1.3 million of decreased PPM and Diary service-related costs incurred during 2010 while the PPM panels were being built for the final 15 PPM Markets commercialized during the last half of 2010.

Selling, General, and Administrative. Selling, general, and administrative increased by 1.5% or $0.3 million for the three months ended September 30, 2011, as compared to the same period in 2010. Selling, general, and administrative increased primarily due to $0.9 million in Arbitron Mobile-related costs incurred during the third quarter ended September 30, 2011, and a $0.8 million increase in short-term employee incentive compensation expense. These increases were partially offset by a $1.4 million decrease associated with employee separation charges incurred during the third quarter of 2010.

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

28

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 increased by 42.9% or $7.8 million for the three-month period ended September 30, 2011, as compared to the same period in 2010, primarily due to an increase in revenue associated with the PPM service transition and a reduction in costs and other expenses. However, EBITDA increased by 32.4% or $8.2 million because this non-GAAP financial measure adds back depreciation and amortization, which only increased 5.5% to $7.5 million for the three-month period ended September 30, 2011, from $7.1 million for the same period in 2010.

Revenue. Revenue increased by 6.5% or $18.5 million for the nine-month period ended September 30, 2011, as compared to the same period in 2010. PPM-based ratings service revenue increased by $42.3 million primarily due to the impact of the five PPM Markets commercialized during the fourth quarter of 2010, as well as price escalators in all PPM commercialized markets. This increase in revenue was partially offset by a $25.5 million decrease in revenue related to the transition from our Diary-based ratings service.

Cost of Revenue. Cost of revenue increased by 2.0% or $3.1 million for the nine-month period ended September 30, 2011, as compared to the same period in 2010. Cost of revenue increased primarily due to $2.5 million of increased PPM service-related costs incurred to manage PPM panels for the 48 PPM Markets commercialized as of September 30, 2011, as compared to the 43 PPM Markets commercialized as of September 30, 2010. Cost of revenue was also impacted by a $0.9 million increase in costs related to our computer center operations. These increases in cost of revenue were partially offset by a $1.8 million of lower Diary-based service costs related primarily to the corresponding reduction in the number of Diary markets.

Selling, General, and Administrative. Selling, general, and administrative decreased by 1.4% or $0.8 million for the nine-month period ended September 30, 2011, as compared to the same period in 2010. Selling, general, and administrative decreased primarily due to a $3.8 million decrease in employee separation charges, a $1.2 million supplemental retirement plan settlement charge incurred during 2010. These decreases were partially offset by a $1.7 million increase in share-based and long-term employee incentive compensation expense, a $1.1 million in Arbitron Mobile-related costs incurred during 2011, and an $0.8 million increase in short-term employee incentive compensation expense for the nine-month period ended September 30, 2011, as compared to the same period in 2010.

31

Research and Development. Research and development decreased by 5.5% or $1.6 million for the nine-month period ended September 30, 2011, as compared to the same period in 2010. Research and development decreased primarily due to a $2.2 million reduction in development costs related to our Diary service, a $0.6 million reduction in development costs related to our client software, and a $0.6 million reduction in development costs related to our PPM service, partially offset by $0.5 million in royalty costs associated with certain technology licenses.

Income tax expense. Income tax expense increased by 45.7% or $8.0 million for the nine-month period ended September 30, 2011, as compared to the same period in 2010. The effective tax rate increased to 39.5% for the nine months ended September 30, 2011, from 37.8% for the nine months ended September 30, 2010. The increase includes the estimated effect of certain Arbitron Mobile operating losses, which are subject to limitation, and may not be available to offset future taxable income.

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.

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 increased by 38.1% or $17.9 million for the nine-month period ended September 30, 2011, as compared to the same period in 2010, primarily due to an increase in revenue associated with the PPM service transition and a decrease in operating expenses due largely to reduced research and development charges in comparison to prior year expenditures. However, EBITDA increased by 29.2% or $19.7 million because this non-GAAP financial measure adds back depreciation and amortization, which only increased 8.6% to $22.1 million for the nine-month period ended September 30, 2011 from $20.3 million for the same period in 2010.

Liquidity and Capital Resources

	As of September  30, 2011		As of December  31, 2010			Change
Cash and cash equivalents	$	15,985	$	18,925		$	(2,940	)
Working capital surplus (deficiency)	$	3,183	$	(32,333	)	$	35,516

Total debt	$	—	$	53,000		$	(53,000	)

We have relied upon our cash flow from operations, supplemented by borrowings under our available revolving credit facility (“Credit Facility”) as needed, to fund our dividends, capital expenditures, contractual obligations, and expenses. 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 and any replacement credit arrangement will be sufficient to support our operations for the next 12 months. We expect to renew or replace our revolving credit facility prior to December 20, 2011, the Credit Facility’s expiration date. See “Credit Facility” for further discussion of the relevant terms and covenants.

Operating activities. For the nine-month period ended September 30, 2011, the net cash provided by operating activities was $89.6 million, which was primarily due to $87.2 million in EBITDA, partially offset by $21.1 million in income taxes paid for the nine-month period ended September 30, 2011. EBITDA is discussed and reconciled to net income in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations.”

Net cash provided by operating activities for the nine-month period ended September 30, 2011, was positively impacted by a $9.3 million increase associated with reductions in accounts receivable due primarily to higher collections received and an $8.2 million increase in deferred revenue, primarily due to price escalators associated with our PPM ratings service.

These increases in operating activities for the nine-month period ended September 30, 2011, were partially offset by a $8.7 million decrease in accrued expenses and other current liabilities, which resulted primarily from a $6.0 million decrease in our Scarborough royalty accrual, and a $1.4 million decrease in payroll, bonus and benefit accruals.

Investing activities. Net cash used in investing activities for the nine-month periods ended September 30, 2011, and 2010, was $33.6 million and $32.0 million, respectively. This approximately $1.6 million increase in cash used in investing activities for the nine-month period ended September 30, 2011 as compared to the same period of 2010, was due primarily to a $8.1 million net increase in business acquisitions, which included a $10.6 million cash outlay for the purchase of Zokem Oy during the third quarter of 2011, and a $2.5 million asset acquisition during the second quarter of 2010. This increase in investing activities was partially offset by decreases related to a $4.5 million licensing arrangement during the first quarter of 2010 and a $1.8 million purchase of equity and other investments during the second quarter of 2010.

Financing activities. Net cash used in financing activities for the nine-month periods ended September 30, 2011, and 2010, was $59.0 million and $17.1 million, respectively. The $41.9 million increase in net cash used in financing activities was due primarily to a $43.0 million increase in the net repayment of our outstanding obligations under our Credit Facility during 2011, as compared to 2010, and a $1.1 million repayment related to Zokem Oy debt assumed in the related acquisition. Net cash used in financing activities also included an increase related to a $2.0 million reduction in stock option exercises for 2011, as compared to 2010, when a substantial number of stock options were nearing their expiration date during the prior year. These increases to net cash used in financing activities were partially offset by a $3.8 million reversal of a bank overdraft payable during the first quarter of 2010.

33

Credit Facility

On December 20, 2006, we entered into an agreement with a consortium of lenders to provide up to $150.0 million of financing through a five-year, unsecured revolving credit facility. Our Credit Facility is scheduled to expire on December 20, 2011. We expect to renew or replace our Credit Facility prior to its expiration.

The Credit Facility agreement contains an expansion feature for us to increase the total financing available under the Credit Facility by up to $50.0 million for an aggregate of up to $200.0 million in financing. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of our current lenders, 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 as selected by us.

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 12-month 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 obligations. The following table presents the actual ratios and their threshold limits as defined by the Credit Facility as of September 30, 2011:

Covenant	Threshold		Actual
Maximum leverage ratio		3.0		0.0
Minimum interest coverage ratio		3.0		207.0

As of September 30, 2011, 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, 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 that 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 capital when needed or could prevent us from investing in other growth initiatives. As of September 30, 2011, and October 31, 2011, we had no outstanding debt under the Credit Facility. Our outstanding borrowings under the Credit Facility was $53.0 million as of December 31, 2010. We have been in compliance with the terms of the Credit Facility since the agreement’s inception.

Other Liquidity Matters

Recruitment of younger demographic groups through cell phone household and targeted in-person recruiting initiatives for both our Diary and PPM services has increased and will continue to increase our cost of revenue as we strive to continue to improve the quality of our samples. We believe that 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 for the next 12 months.

Seasonality

Revenue

We recognize revenue for services over the terms of license agreements as services are delivered while expenses are recognized as incurred. We currently gather radio-listening data in 284 U.S. local markets, including 236 Diary markets and 48 PPM Markets.

In our PPM markets, we deliver ratings 13 times a year, with four PPM ratings reports delivered in the fourth quarter. As a result, we expect to recognize more revenue in PPM Markets in the fourth quarter than in each of the first three quarters of the year.

As we commercialized the PPM service, our deferred revenue decreased compared to our historical trends due to the more frequent delivery of our PPM service, which is delivered 13 times a year versus the quarterly and semi-annual delivery for our Diary service. The commercialization of the PPM service in the PPM Markets was completed at the end of 2010. We expect that approximately one year after the completion of the commercialization of the PPM service in the PPM Markets , deferred revenue will begin to increase, as compared to trends during the commercialization of the PPM service, due to the impact of price escalators and the organic growth of our business.

During the transition period from the Diary service to PPM service in each PPM Market, there were changes in the seasonality pattern because during the initial quarter in which the PPM ratings service is commercialized in a market, we recognize revenue based on the delivery of both the final quarterly Diary ratings and the initial monthly PPM ratings for that market.

All 236 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 48 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 48 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, we typically expect that the highest consolidated revenue quarter for the year would be the fourth quarter and the lowest would be the second quarter.

Costs and expenses

The transition from the Diary service to the PPM service in the PPM Markets also had an impact on the seasonality of costs and expenses. PPM costs and expenses generally increased six to nine months in advance of the commercialization of each market as we built the PPM panels. These build-up costs were incremental to the costs associated with our Diary-based ratings service and we recognized these increased costs as incurred rather than upon the delivery of a particular survey.

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 236 of our Diary Markets.

35

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. Scarborough royalty costs, which are recognized in cost of revenue, are also higher during the second and fourth quarters.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

The Company holds its cash and cash equivalents in highly liquid securities.

Foreign Currency Exchange Rate Risk

The Company’s foreign operations are not significant and, therefore, its exposure to foreign currency risk is not material. If we expand our foreign operations, this exposure to foreign currency exchange rate changes could increase.

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 September 30, 2011, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

37

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 April 30, 2008, Plumbers and Pipefitters Local Union No. 630 Pension-Annuity Trust Fund filed a securities class action lawsuit in the United States District Court for the Southern District of New York on behalf of a purported Class of all purchasers of Arbitron common stock between July 19, 2007, and November 26, 2007. The plaintiff asserts that Arbitron, Stephen B. Morris (our former Chairman, President and Chief Executive Officer), and Sean R. Creamer (currently our Executive Vice President, Chief Operating Officer & formerly Chief Financial Officer) violated federal securities laws. The plaintiff alleges misrepresentations and omissions relating, among other things, to the delay in commercialization of our PPM ratings service in November 2007, as well as stock sales during the period by company insiders who were not named as defendants and Messrs. Morris and Creamer. The plaintiff seeks class certification, compensatory damages plus interest and attorneys’ fees, among other remedies. On September 22, 2008 the plaintiff filed an Amended Class Action Complaint. On November 25, 2008, Arbitron, Mr. Morris, and Mr. Creamer each filed Motions to Dismiss the Amended Class Action Complaint. In September 2009, the plaintiff sought leave to file a Second Amended Class Action Complaint in lieu of oral argument on the pending Motions to Dismiss. The court granted leave to file a Second Amended Class Action Complaint and denied the pending Motions to Dismiss without prejudice. On or about October 19, 2009, the plaintiff filed a Second Amended Class Action Complaint. Briefing on motions to dismiss the Second Amended Class Action Complaint was completed in March 2010. Arbitron and each of Mr. Morris and Mr. Creamer again moved to dismiss the Second Amended Class Action Complaint. On September 24, 2010, the Court granted Mr. Creamer’s motion to dismiss the plaintiff’s claims against him, and all claims against Mr. Creamer were dismissed with prejudice. The motions to dismiss the Second Amended Class Action Complaint by Arbitron and Mr. Morris were denied. Arbitron and Mr. Morris each then filed answers denying the claims. On September 6, 2011, the Court entered an order granting the plaintiff’s motion to certify the action as a class action, to appoint the lead plaintiff as class representative, and to appoint its counsel as lead counsel. The court defined the class as all purchasers of common stock of the Company who were damaged through purchasing stock during the period July 19, 2007 through November 26, 2007. The case is continuing in the discovery phase.

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 reiterates, in large part, the claims of the original complaint filed in 2008. The amended complaint also adds 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 seeks equitable and/or injunctive relief, restitution and disgorgement of profits, plus attorneys’ fees and costs, among other remedies.

The Company intends to defend itself and its interests vigorously against these allegations.

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.

38

Item 1A. Risk Factors

The only material changes to our risk factors as described in our annual report on Form 10-K for the year ended December 31, 2010 are to add the following:

Our acquisition of businesses could negatively impact our results of operations and financial condition.

As part of our business strategy we may acquire businesses or other assets. Such acquisitions involve a number of financial, accounting, managerial, operational and other risks and challenges, including the following, any of which could adversely affect our profitability:

• Any acquired business, technology, service, or asset could under-perform relative to our expectations and the price that we paid for it, or not perform in accordance with our anticipated timetable.

• Acquisitions could cause our financial results to differ from our own or the investment community’s expectations in any given period, or over the long-term.

• Acquisition-related earnings charges (including both pre-closing and post-closing charges) could adversely impact operating results in any given period, and the impact may be substantially different from period to period.

• Acquisitions could create demands on our management, operational resources and financial and internal control systems that we are not equipped to handle.

• We could experience difficulty in integrating personnel, operations and financial and other systems and retaining key employees and customers.

• We may be unable to achieve cost savings or other synergies anticipated in connection with an acquisition.

• We may assume by acquisition unknown liabilities, known contingent liabilities that become realized, known liabilities that prove greater than anticipated, or internal control deficiencies. The realization of any of these liabilities or deficiencies may increase our expenses, adversely affect our financial position or cause us to fail to meet our public financial reporting obligations.

• In connection with acquisitions, we may enter into post-closing financial arrangements such as purchase price adjustments, earn-out obligations and indemnification obligations, which may have unpredictable financial results.

• As a result of any acquisitions, we may record significant goodwill and other indefinite lived intangible assets on our balance sheet. If we are not able to realize the value of these assets, we may be required to incur charges relating to the impairment of these assets.

Foreign currency exchange rates may adversely affect our results of operations and financial condition.

Sales and purchases in currencies other than the U.S. dollar expose us to fluctuations in foreign currencies relative to the U.S. dollar and may adversely affect our results of operations and financial condition. Increased strength of the U.S. dollar will increase the effective price of our services sold in U.S. dollars into other countries, which may require us to lower our prices or adversely affect sales to the extent we do not increase local currency prices. Decreased strength of the U.S. dollar could adversely affect the cost of materials, products and services purchased overseas. Our sales and expenses are also translated into U.S. dollars for reporting purposes and the strengthening or weakening of the U.S. dollar could result in unfavorable translation effects.

39

Work stoppages, union and works council campaigns, labor disputes and other matters associated with our international employees could adversely impact our results of operations and cause us to incur incremental costs.

Certain of our international employees are subject to non-U.S. collective labor arrangements. We are subject to potential work stoppages, union and works council campaigns and potential labor disputes, any of which could adversely impact our productivity and results of operations.

EX-10.1

Exhibit 10.1

ARBITRON INC. 2008 EQUITY COMPENSATION PLAN

NON-STATUTORY STOCK OPTION AGREEMENT

THIS AGREEMENT evidences the grant by Arbitron Inc. (the “Company”) on                 , 201     (the “Date of Grant”) to                                          (the “Optionee”) of an option to purchase shares of the Company’s common stock.

A. The Company has adopted the Arbitron Inc. 2008 Equity Compensation Plan (as may be amended or supplemented, the “Plan”) authorizing the Board of Directors of the Company, or a committee as provided for in the Plan (the Board or such a committee to be referred to as the “Committee”), to grant stock options to employees of the Company and its Subsidiaries (as defined in the Plan).

B. The Company desires to give the Optionee an inducement to acquire a proprietary interest in the Company and an added incentive to advance the interests of the Company by granting to the Optionee an option to purchase shares of common stock of the Company pursuant to the Plan.

Accordingly, the parties agree as follows:

1. Grant of Option.

The Company has granted to the Optionee the right, privilege and option (the “Option”) to purchase [Shares] shares (the “Option Shares”) of the Company’s common stock, $0.50 par value (the “Common Stock”), according to the terms and subject to the conditions hereinafter set forth and as set forth in the Plan. The Option is not intended to be an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”).

2. Option Exercise Price.

The per share price to be paid by Optionee in the event of an exercise of the Option will be $        .

3. Duration of Option and Time of Exercise.

3.1 Initial Period of Exercisability. Except as provided in Sections 3.2 and 3.3 hereof, the Option shall become exercisable with respect to one-third of the Option Shares on each of the first, second and third anniversaries of the Date of Grant, assuming the Optionee’s continued employment. The foregoing rights to exercise the Option will be cumulative with respect to the Option Shares becoming exercisable on each such date, but in no event will the Option be exercisable after, and the Option will become void and expire as to all unexercised Option Shares at, 5:00 p.m. (Eastern Standard Time) on the tenth anniversary of the Date of Grant (the “Time of Option Termination”).

3.2 Termination of Employment.

(a) Termination Due to Death or Disability. In the event the Optionee’s employment with the Company and all Subsidiaries is terminated by reason of death or Disability, the Option will become immediately exercisable in full and remain exercisable until the Time of Option Termination.

(b) Termination by Optionee as Retirement. In the event the Optionee’s employment with the Company and all Subsidiaries ends through the Optionee’s Retirement, the Option will continue to vest as though the Optionee remained employed and will remain exercisable as of and after such vesting until the Time of Option Termination.

(c) Termination by the Company without Cause or through Voluntary Resignation other than on Retirement. In the event that the Optionee’s employment with the Company and all Subsidiaries ends by the Optionee’s termination without Cause or through his or her resignation other than on a Retirement, any unvested portions of the Option will expire on employment termination and the vested portions of the Option will remain exercisable as of and after such vesting until the earlier of the 90th day following such resignation or the Time of Option Termination.

(d) Termination by the Company for Cause. In the event that the Optionee’s employment with the Company and all Subsidiaries is terminated by the Company for Cause, any vested or unvested portions of the Option will immediately expire and be forfeited.

(e) 280G; Release Requirement. Any acceleration, vesting, or extension under this Section 3.2 is subject, as applicable, to the 280G provisions in Exhibit I hereto and to compliance with any requirement that otherwise applies to the Optionee to provide a release of claims.

3.3 Change in Control.

(a) Impact of Change in Control.

(i) If a Change in Control Event of the Company occurs, the Committee, in its sole discretion and without the consent of the Optionee, may determine that the Optionee will receive, with respect to some or all of the Option Shares, as of the effective date of any such Change in Control Event of the Company, cash in an amount equal to the excess of the Fair Market Value (as defined in the Plan) of such Option Shares as determined by taking into account such Change in Control Event of the Company over the option exercise price per share of the Option.

(ii) If a Change in Control Event occurs and the Option is not assumed or replaced, it shall immediately become fully exercisable. If the Option is assumed or replaced, exercisability fully accelerates if, within 24 months following the closing of the Change in Control Event, the Optionee’s employment is terminated without Cause or, if his or her employment or other individual agreement provides for resignation for “Good Reason,” upon a resignation for Good Reason during the same period.

(b) Authority to Modify Change in Control Provisions. Prior to a Change in Control Event, the Optionee will have no rights under this Section 3.3, and the Committee will have the authority, in its sole discretion, to rescind, modify, or amend this Section 3.3 without the consent of the Optionee.

2

4. Manner of Option Exercise.

4.1 Notice. This Option may be exercised by the Optionee in whole or in part from time to time, subject to the conditions contained in the Plan and in this Agreement, by delivery, in person, by facsimile or electronic transmission or through the mail, to the Company at its principal executive office in Columbia, Maryland (Attention: Corporate Secretary), of a written notice of exercise. Such notice must be in a form satisfactory to the Committee, must identify the Option, must specify the number of Option Shares with respect to which the Option is being exercised, and must be signed by the person or persons so exercising the Option. In the event that the Option is being exercised, as provided by the Plan and Section 3.2 of this Agreement, by any person or persons other than the Optionee, the notice must be accompanied by appropriate proof of right of such person or persons to exercise the Option. If the Optionee retains the Option Shares purchased, as soon as practicable after the effective exercise of the Option, the Optionee will be recorded on the stock transfer books of the Company as the owner of the Option Shares purchased.

4.2 Payment. At the time of exercise of the Option, the Optionee must pay the total exercise price of the Option Shares to be purchased entirely in cash (including a check, bank draft or money order, payable to the order of the Company), though a cashless exercise as described in Section 5(f)(2) of the Plan, by such other method approved by the Committee, or by a combination of such methods.

5. Rights and Restrictions of Optionee; Transferability.

5.1 Employment. Nothing in this Agreement will interfere with or limit in any way the right of the Company or any Subsidiary to terminate the employment of the Optionee at any time, nor confer upon the Optionee any right to continue in the employ of the Company or any Subsidiary at any particular position or rate of pay or for any particular period of time.

5.2 Rights as a Stockholder; Effect on Running the Business. The Optionee will have no rights as a stockholder unless and until all conditions to the effective exercise of the Option (including, without limitation, the conditions set forth in Sections 4 and 6 of this Agreement) have been satisfied and the Optionee has become the holder of record of such shares. No adjustment will be made for dividends or distributions with respect to the Option Shares as to which there is a record date preceding the date the Optionee becomes the holder of record of such Option Shares, except as may otherwise be provided in the Plan or determined by the Committee in its sole discretion. The Optionee understands and agrees that the existence of an Option will not affect in any way the right or power of the Company or its stockholders to make or authorize any adjustments, recapitalizations, reorganizations, or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issuance of bonds, debentures, preferred or other stock, with preference ahead of or convertible into, or otherwise affecting the Company’s common stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether or not of a similar character to those described above.

5.3 Restrictions on Transfer. Except pursuant to testamentary will or the laws of descent and distribution or as otherwise expressly permitted by the Plan, no right or interest of the Optionee in the Option prior to exercise may be assigned or transferred, or subjected to any lien, during the lifetime of the Optionee, either voluntarily or involuntarily, directly or indirectly, by operation of law or otherwise. The Optionee will, however, subject to applicable laws be entitled to designate a beneficiary to receive the Option upon such Optionee’s death in the manner provided by the Plan, and, in the event of the Optionee’s death, exercise of the Option (to the extent permitted pursuant to Section 3.2(a) of this Agreement) may be made by the Optionee’s designated beneficiary.

3

5.4 Restrictions Regarding Employment.

(a) The Optionee agrees that he or she will not take any Adverse Actions (as defined below) against the Company or any Subsidiary at any time during the period that the Option is or may yet become exercisable in whole or in part or at any time before one year following the Optionee’s cessation of employment with the Company or any Subsidiary, whichever is later (the “Restricted Period”). The Optionee acknowledges that damages that may arise from a breach of this Section 5.4 may be impossible to ascertain or prove with certainty. Notwithstanding anything in this Agreement or the Plan to the contrary, in the event that the Company determines in its sole discretion that the Optionee has taken Adverse Actions against the Company or any Subsidiary at any time during the Restricted Period, in addition to other legal remedies that may be available, (i) the Company will be entitled to an immediate injunction from a court of competent jurisdiction to end such Adverse Action, without further proof of damage, (ii) the Committee will have the authority in its sole discretion to terminate immediately all rights of the Optionee under the Plan and this Agreement without notice of any kind, and (iii) the Committee will have the authority in its sole discretion to rescind the exercise of all or any portion of the Option to the extent that such exercise occurred within six months prior to the date the Optionee first commences any such Adverse Actions and require the Optionee to disgorge any profits (however defined by the Committee) realized by the Optionee relating to such exercised portion of the Option or any Option Shares issued or issuable upon such exercise. Such disgorged profits paid to the Company must be made in cash (including check, bank draft or money order) or, with the Committee’s consent, shares of Common Stock with a Fair Market Value on the date of payment equal to the amount of such payment. The Company will be entitled to withhold and deduct from future wages of the Optionee (or from other amounts that may be due and owing to the Optionee from the Company or a Subsidiary) or make other arrangements for the collection of all amounts necessary to satisfy such payment obligation.

(b) For purposes of this Agreement, an “Adverse Action” will mean any of the following: (i) engaging in any commercial activity in competition with any part of the business of the Company or any Subsidiary as conducted during the Restricted Period for which the Optionee has or had access to trade secrets and/or confidential information; (ii) diverting or attempting to divert from the Company or any Subsidiary any business of any kind, including, without limitation, interference with any business relationships with suppliers, customers, licensees, licensors, clients or contractors; (iii) participating in the ownership, operation or control of, or being employed by, or connected in any manner with any person or entity that solicits, offers or provides any services or products similar to those which the Company or any Subsidiary offers to its customers or prospective customers, (iv) making, or causing or attempting to cause any other person or entity to make, any statement, either written or oral, or convey any information about the Company or any Subsidiary that is disparaging or that in any way reflects negatively on the Company or any Subsidiary; or (v) engaging in any other activity that is hostile, contrary or harmful to the interests of the Company or any Subsidiary, including, without limitation, influencing or advising any person who is employed by or in the service of the Company or any Subsidiary to leave such employment or service to compete with the Company or any Subsidiary or to enter into the employment or service of any actual or prospective competitor of the Company or any Subsidiary, influencing or advising any competitor of the Company or any Subsidiary to employ to otherwise engage the services of any person who is employed by or in the service of the Company or any Subsidiary, or improperly disclosing or otherwise misusing any trade secrets or confidential information regarding the Company or any Subsidiary.

4

(c) Should any provision of this Section 5.4 of the Agreement be held invalid or illegal, such illegality shall not invalidate the whole of this Section 5.4 of the Agreement, but, rather, the Agreement shall be construed as if it did not contain the illegal part or narrowed to permit its enforcement, and the rights and obligations of the parties shall be construed and enforced accordingly. In furtherance of and not in limitation of the foregoing, the Optionee expressly agrees that should the duration of or business activities covered by, any provision of this Agreement be in excess of that which is valid or enforceable under applicable law, then such provision shall be construed to cover only that duration, extent or activities that may validly or enforceably be covered. The Optionee acknowledges the uncertainty of the law in this respect and expressly stipulates that this Agreement shall be construed in a manner that renders its provisions valid and enforceable to the maximum extent (not exceeding its express terms) possible under applicable law. This Section 5.4 of the Agreement does not replace and is in addition to any other agreements the Optionee may have with the Company or any of its Subsidiaries on the matters addressed herein.

7. Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets as of September 30, 2011, and December 31, 2010, consist of the following (in thousands):

	September 30, 2011		December 31, 2010
Survey participant incentives and prepaid postage	$	2,432	$	2,441
Insurance recovery receivable		845		601

Prepaid expenses and other current assets	$	8,670	$	11,332

During 2008, the Company became involved in two securities-law civil actions and a governmental interaction primarily related to the commercialization of our PPM service. The management of the Company believes a portion of these legal fees and costs are covered by the Company’s Directors and Officers insurance policy and therefore has recognized an insurance recovery receivable. From 2008 until September 30, 2011, the Company had incurred approximately $11.0 million in legal fees and costs in defense of its positions related thereto, and as of September 30, 2011, the Company had received $7.1 million in insurance reimbursements related to these legal actions. From 2008 until December 31, 2010, the Company had incurred approximately $9.7 million in legal fees and costs in defense of its positions related thereto, and as of December 30, 2010, the Company had received $5.9 million in insurance reimbursements.

For the nine-month periods ended September 30, 2011, and 2010, the Company incurred approximately $1.3 million, and $0.3 million, respectively, in related legal fees, which were recognized as increases to selling, general, and administrative expense. These legal fees were offset by $1.4 million and $0.4 million in anticipated insurance recoveries, which were recognized as reductions to selling, general and administrative expense during the nine-month periods ended September 30, 2011, and 2010, respectively.

Taxes [Abstract]

Taxes

12. Taxes

The effective tax rate increased to 39.5% for the nine months ended September 30, 2011, from 37.8% for the nine months ended September 30, 2010. The increase includes the estimated effect of certain Arbitron Mobile operating losses, which are subject to limitation, and may not be available to offset future taxable income.

During 2011, the Company’s net unrecognized tax benefits for certain tax contingencies decreased from $1.9 million as of December 31, 2010, to $1.1 million as of September 30, 2011. The decrease is attributable to the settlement of a state audit and expiration of statutes of limitations in various jurisdictions. 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 nine-months ended September 30, 2011 and 2010, were $21.1 million and $19.4 million, respectively.

Debt

3. Debt

The Company has an agreement with a consortium of lenders to provide up to $150.0 million of financing to the Company through an unsecured revolving credit facility (the “Credit Facility”), expiring on December 20, 2011. The agreement contains an expansion feature for the Company to increase the total financing available under the Credit Facility by up to $50.0 million for an aggregate of up to $200.0 million in financing. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of the lenders, and/or in combination with one or more new lending institutions, subject to the approval of the Credit Facility’s administrative agent.

The Company expects to renew or replace the Credit Facility prior to its expiration. As of September 30, 2011, there were no outstanding borrowings under the Credit Facility. As of December 31, 2010, the outstanding borrowings balance under the Credit Facility was $53.0 million.

Interest paid during each of the nine-month periods ended September 30, 2011, and 2010, was $0.3 million and $0.7 million, respectively.

9. Acquisitions

Zokem Oy. On July 28, 2011, a wholly-owned subsidiary of the Company acquired Zokem Oy, a Finland-based mobile audience measurement and analytics firm now known as Arbitron Mobile. The purchase price was $10.6 million in cash plus a contingent consideration arrangement with an estimated fair value of approximately $0.9 million. The agreement provides for possible additional cash payments to be made through 2015 of up to $12.0 million, which are contingent upon Zokem reaching certain financial performance targets in the future. The $0.9 million fair value estimate was determined by applying the income approach methodology. The key assumptions used in the fair value valuation include a probability-weighted range of performance targets for the 4–year measurement period of 2012 through 2015 and an adjusted discount rate. The Company will periodically reassess the fair value of the contingent consideration.

The following table shows the preliminary assets and liabilities acquired (in thousands):

Asset and liabilities acquired	Amount
Trade receivables	$	334
Computer equipment		31
Other intangible assets
Acquired software and trademarks		5,313
Non-compete agreement		238
Customer relationships		1,504

Accounts payable		(130	)

Noncurrent liabilities		(1,172	)
Net assets acquired		5,921
Goodwill		5,623
Total purchase price, net of cash acquired	$	11,544

As of September 30, 2011, the purchase price allocation and related goodwill estimate are preliminary amounts that will be adjusted in the future for certain working capital and tax-related adjustments. The other intangible assets are being amortized over a weighted average life of 5.3 years. The amount of acquisition-related costs incurred and charged to selling, general and administrative expense during the nine-month period ended September 30, 2011, was $0.6 million.

Integrated Media Measurement, Inc. On June 15, 2010, a wholly-owned subsidiary of the Company purchased the technology portfolio, trade name, and equipment of Integrated Media Measurement, Inc. The Company paid $2.5 million for these assets, which included $1.8 million of other intangible assets, $0.3 million of computer equipment, and $0.4 million of goodwill. The other intangible assets are being amortized over 5.0 years.

Digimarc Corporation. On March 23, 2010, the Company entered into a licensing arrangement with Digimarc Corporation (“Digimarc”) to receive a non-exclusive, worldwide and irrevocable license to a substantial portion of Digimarc’s domestic and international patent portfolio. The Company paid $4.5 million for this other intangible asset, which is being amortized over 7.0 years.

Future amortization expense of the Company’s $12.2 million of other intangible assets recorded on the consolidated balance sheet as of September 30, 2011, is estimated to be as follows:

	Amount
3-Month Period Ended December 31, 2011	$	634

Net Income per Weighted-Average Common Share

5. Net Income per Weighted-Average Common Share

The computations of basic and diluted net income per weighted-average common share for the three and nine-month periods ended September 30, 2011, and 2010, 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 that the proceeds from the exercise of all stock options are used to repurchase the Company’s common stock at the average market price for the period. As of September 30, 2011, and 2010, there were stock options to purchase 2,094,214 and 2,248,119 shares, respectively, of the Company’s common stock outstanding, of which stock options to purchase 1,102,228 and 1,530,410 shares of the Company’s common stock, respectively, were excluded from the computation of diluted net income per weighted-average common share for the quarters ended September 30, 2011, and 2010, 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.

Stock Options

Stock options awarded to employees under the 2001 Stock Incentive Plan and the 2008 Equity Compensation Plan (referred to herein collectively as the “SIPs”) generally vest annually over a three-year period, have a 10-year term and have an exercise price of not less than the fair market value of the Company’s common stock at the date of grant. For stock options granted prior to 2010, the Company’s stock option agreements generally provide for accelerated vesting if there is a change in control of the Company. Effective for stock options granted in 2010 and after, the Company’s stock option agreements provide for accelerated vesting if (i) there is a change in control of the Company and (ii) the participant’s employment terminates during the 24-month period following the effective date of the change in control for one of the reasons specified in the stock option agreement.

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. The Company uses historical data to estimate future option exercises and employee terminations in order to determine the expected term of the stock option, where the expected term of stock option granted represents the period of time that such stock option is expected to be outstanding. Identified groups of option holders with similar historical exercise behavior are considered separately for valuation purposes. The expected term of stock options can vary for groups of option holders exhibiting different behavior. The fair value of each stock option granted to employees and nonemployee directors during the nine-month periods ended September 30, 2011, and 2010, was estimated on the date of grant using a Black-Scholes stock option valuation model, which uses a risk-free interest rate and measure of volatility, among other things, to estimate fair value. The risk-free interest rate for periods within the contractual life of the stock option is based on the U.S. Treasury strip bond yield curve in effect at the time of grant. Expected volatilities are based on the historical volatility of the Company’s common stock.

For the three-month period ended September 30, 2011, the number of stock options granted was 81,001 and the weighted-average exercise price for those stock options granted was $34.83. For the three-month period ended September 30, 2010, no stock options were granted.

For the nine-month periods ended September 30, 2011 and 2010, the number of stock options granted was 154,226 and 288,544, respectively, and the weighted-average exercise price for those stock options granted was $39.21 and $22.84, respectively.

As of September 30, 2011, there was $3.0 million in total unrecognized compensation cost related to stock options granted under the SIPs. This aggregate unrecognized cost is expected to be recognized over a weighted-average remaining period of 2.0 years. The weighted-average exercise price and weighted-average remaining contractual term for outstanding stock options as of September 30, 2011, were $33.11 and 5.88 years, respectively, and as of September 30, 2010, $31.78 and 6.21 years, respectively.

Service and Performance Award Units

Service award units. During the nine-month period ended September 30, 2011, the Company granted service award shares under the SIPs. These service award units (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) vest in four equal annual installments beginning on the first anniversary date of the grant, and (iii) for any unvested units, expire without vesting if the employee is no longer employed by the Company. For those service award units granted prior to 2010, the service award units generally provide for accelerated vesting if there is a change in control of the Company. Effective for service award units granted in 2010 and after, the service award units provide for accelerated vesting if (i) there is a change in control of the Company and (ii) the participant’s employment terminates during the 24-month period following the effective date of the change in control for one of the reasons specified in the restricted stock unit agreement.

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 September 30, 2011, there was $2.4 million of total unrecognized compensation cost related to service award units granted under the SIPs. This aggregate unrecognized cost for service award units is expected to be recognized over a weighted-average period of 2.09 years.

Additional information for the three-and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,

Number of service award shares granted during the period		—		—		18,434		—
Weighted average grant-date fair value per share		—		—	$	42.72		—
Fair value of service award shares vested during the period	$	322	$	248	$	2,536	$	2,438

Performance award units. During the nine-month periods ended September 30, 2011 and 2010, the Company granted performance award units under the SIPs. 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 expire without vesting if the Company’s return on invested capital (“ROIC”) for the annual performance period does not exceed 12 percent, which is an approximation of the Company’s weighted average cost of capital, (iii) will, if the Company’s ROIC exceeds 12 percent, vest in four equal annual installments beginning on the first anniversary date of the grant, and (iv) for any unvested units, expire without vesting if the recipient is no longer employed by the Company. The Company’s performance award units provide for accelerated vesting if (i) there is a change in control of the Company and (ii) the recipient’s employment terminates during the 24-month period following the effective date of the change in control for one of the reasons specified in the performance-based restricted stock unit agreement.

Compensation expense for performance award units is recognized using the fair market value of the Company’s common stock on the date of grant and on an accelerated basis. The Company recognizes expense for these performance award units under the assumption that the performance ROIC target will be achieved. If it appears such performance ROIC target will not be met, the Company will stop recognizing any further compensation cost and any previously recognized compensation cost would be reversed. As of September 30, 2011, there was $2.4 million of total unrecognized compensation cost related to performance award units granted under the SIPs. This aggregate unrecognized cost is expected to be recognized over a weighted-average period of 3.26 years.

Additional information for the three- and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

Deferred Stock Units

Service award grant to CEO. During the nine-month periods ended September 30, 2011 and 2010, the Company granted service-based deferred stock unit awards (“Service DSUs”) under the SIPs to its CEO. Service DSUs are issued 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. The Service DSUs, if vested, will be convertible into shares of the Company’s common stock following the holder’s termination of employment. The Service DSUs provide for accelerated vesting upon termination without cause or the CEO’s retirement as defined in his employment agreement. No Service DSUs were converted into shares of the Company’s common stock during the nine-month periods ended September 30, 2011, and 2010.

Compensation expense for Service 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 September 30, 2011, there was $0.2 million of total unrecognized compensation cost related to Service DSUs. This aggregate unrecognized cost is expected to be recognized over the weighted-average period of 0.28 years.

Additional information for the three- and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,

Weighted-average grant date fair value per share		—		—	$	44.44	$	24.94
Fair value of shares vested during the period		—		—	$	704		—

Performance award grant to CEO. During the nine-month periods ended September 30, 2011 and 2010, the Company granted performance-based deferred stock unit awards (“Performance DSUs”) under the SIPs to its CEO. These Performance DSUs (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) will expire without vesting if the Company’s return on invested capital (“ROIC”) for the annual performance period does not exceed 12 percent, which is an approximation of the Company’s weighted average cost of capital, (iii) will, if the Company’s ROIC exceeds 12 percent, vest in four equal annual installments beginning on the first anniversary date of the grant, and (iv) provide for accelerated vesting upon termination without cause or the CEO’s retirement as defined in his employment agreement. These Performance DSUs, if vested, will be convertible into shares of the Company’s common stock, subsequent to termination of employment.

Compensation expense for Performance DSUs is recognized using the fair market value of the Company’s common stock on the date of grant and on an accelerated basis. The Company recognizes expense for these Performance DSUs under the assumption that the performance target will be achieved. If it appears such performance target will not be met, the Company will stop recognizing any further compensation cost and any previously recognized compensation cost would be reversed. As of September 30, 2011, there was $0.7 million of total unrecognized compensation cost related to Performance DSUs. This aggregate unrecognized cost is expected to be recognized over the weighted-average period of 1.20 years.

Additional information for the three- and nine-month periods ended September 30, 2011, and 2010, is noted in the following table (dollars in thousands, except per share amounts):

Weighted-average grant date fair value per share		—		—	$	44.44	$	22.17
Fair value of shares vested during the period		—		—	$	227		—

Awards for service on Board of Directors (“Board”). The Company issues deferred stock units to its Board of Directors (“Board DSUs”) under the SIPs. 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. Annual grants of Board DSUs vest annually in three equal installments over a three-year period.

In addition to receiving Board DSU grants annually, the Board members have the right to elect to receive all or a portion of their retainer and meeting attendance fees as cash and/or Board DSUs, which vest immediately. Board DSUs are only granted to nonemployee Directors.

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 September 30, 2011, there was $1.4 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 2.30 years.

Testing Goodwill for Impairment. In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2011-08, Intangibles—Goodwill and Other (Topic 350)—Testing Goodwill for Impairment (“ASU 2011-08”), to allow entities to use a qualitative approach to test goodwill for impairment. ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. ASU 2011-08 is effective for the Company for interim and annual periods ended during 2012, with earlier application permitted. The Company does not expect its pending adoption of this guidance to have a material impact to the Company’s consolidated financial statements.

Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements. In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820)—Fair Value Measurement (“ASU 2011-04”), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. ASU 2011-04 is effective for the Company for interim and annual periods ended during 2012 and should be applied prospectively. The Company is currently evaluating the impact of its pending adoption of ASU 2011-04 on its consolidated financial statements.

Multiple-Deliverable Revenue Recognition. In October 2009, the FASB issued Accounting Standards Update No. 2009-13 Revenue Recognition (Topic 605) — Multiple-Deliverable Revenue Arrangements a consensus of the FASB Emerging Issues Task Force (“ASU 2009-13”). This requires companies to allocate revenue in multiple-element arrangements based on an element’s estimated selling price if vendor-specific or other third party evidence of value is not available. ASU 2009-13 is to be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, with earlier application permitted. There was no impact to the Company’s consolidated financial statements related to the adoption of this guidance.

11. 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 also subsidizes healthcare benefits for eligible retired employees who participate in the pension plan and were hired before January 1, 1992. The Company had one nonqualified, unfunded supplemental retirement plan during the nine-month period ended September 30, 2011. The Company sponsored two supplemental retirement plans during the nine-month period ended September 30, 2010, prior to the termination of one of the supplemental plans in the third quarter of 2010.

The components of periodic benefit costs for the defined-benefit pension, postretirement healthcare and supplemental retirement plan(s) were as follows (in thousands):

Settlement and curtailment loss	$	—		$	—		$	—	$	—	$	—	$	1,222

During the nine-month period ended September 30, 2010, the Company recognized a $1.2 million settlement and curtailment loss, primarily as a result of a lump sum distribution paid to a supplemental retirement plan participant which exceeded the service and interest components incurred for that plan. No settlement and curtailment charge was incurred during the nine-month period ended September 30, 2011.

The Company estimates it will contribute $2.2 million to its defined benefit plans during 2011.

Financial Instruments

15. Financial Instruments

The fair values of accounts receivable and accounts payable approximate their carrying values due to their short-term nature. The Company accounts for its $5.2 million investment in TRA’s preferred stock using the cost method of accounting. TRA is closely held and there is not an efficient market in which buyers and sellers determine the fair value of these shares. The Company periodically assesses the fair value of its investment in TRA through comparative analysis and analysis of TRA’s actual and projected financial results. As of September 30, 2011, the Company believes that the fair value of the TRA investment approximates the carrying value of $5.2 million. In the event the fair value of the investment in TRA were to fall below its carrying value in the future, the Company would be required to recognize an impairment loss.

Due to the floating rate nature of the Company’s revolving obligation under its Credit Facility, the carrying amount of $53.0 million in outstanding borrowings as of December 31, 2010, approximates its fair value.
