Notes to Consolidated Financial Statements

March 31, 2012

(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 (“GAAP”) for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included and are of a normal recurring nature. The consolidated balance sheet as of December 31, 2011 was audited as of that date, but all of the information and notes as of December 31, 2011 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, 2011.

Consolidation

The consolidated financial statements of Arbitron for the three-month period ended March 31, 2012, reflect the consolidated financial position, results of operations and cash flows of the Company and its wholly-owned subsidiaries: Arbitron Holdings Inc., Arbitron Mobile Oy, Astro West LLC, Cardinal North LLC, Ceridian Infotech (India) Private Limited, Arbitron International, LLC, and Arbitron Technology Services India Private Limited. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has one segment which meets the quantitative thresholds for being a reportable segment.

2. New Accounting Pronouncements

Testing 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. The adoption of this guidance had no impact on 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 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 will be applied prospectively. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

3. Debt

On November 21, 2011, the Company terminated its credit facility agreement originally signed on December 20, 2006. Also, on November 21, 2011, the Company entered into a new agreement with a consortium of lenders to provide up to $150.0 million of financing to the Company through a five-year, unsecured revolving credit facility (the “Credit Facility”) expiring on November 21, 2016. The agreement contains an expansion feature to increase the total financing available under the Credit Facility by up to $75.0 million to an aggregate of $225.0 million. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of the lending banks, and/or in combination with one or more new lending institutions, subject to the approval of the Credit Facility’s administrative agent.

As of March 31, 2012 and December 31, 2011, there were no outstanding borrowings under the Credit Facility. Interest paid during the three-month periods ended March 31, 2012, and 2011, was less than $0.1 million and $0.2 million, respectively.

4. Stockholders’ Equity

Changes in stockholders’ equity for the three-month period ended March 31, 2012, 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, 2011		27,290		$	16,169	$	(2,524	)	$	128,772		$	(15,601	)	$	126,816

A quarterly cash dividend of $0.10 per common share was paid to stockholders on April 2, 2012. Of the $19.8 million of the Company’s outstanding stock repurchased for the quarter ended March 31, 2012, $2.5 million was paid for in cash during the month ended April 30, 2012.

5. Net Income per Weighted-Average Common Share

The computations of basic and diluted net income per weighted-average common share for the three-month periods ended March 31, 2012 and 2011, are based on the Company’s weighted-average shares of common stock and potentially dilutive securities outstanding. Potentially dilutive securities are calculated in accordance with the treasury stock method, which assumes the proceeds from the exercise of all stock options are used to repurchase the Company’s common stock at the average market price for the period. As of March 31, 2012, and 2011, there were stock options to purchase 2,105,924 shares, and 2,057,790 shares of the Company’s common stock outstanding, respectively, of which stock options to purchase 1,238,880 shares, and 686,876 shares of the Company’s common stock, respectively, were excluded from the computation of the diluted net income per weighted-average common share, either because the stock options’ exercise prices were greater than the average market price of the Company’s common shares or assumed repurchases from proceeds from the stock options’ exercise were antidilutive.

6. Accumulated Other Comprehensive Loss

The components of accumulated other comprehensive loss were as follows (in thousands):

	March 31, 2012			December 31, 2011
Foreign currency translation adjustment	$	(1,755	)	$	(2,148	)
Retirement plan liabilities, net of tax		(13,131	)		(13,453	)
Accumulated other comprehensive loss	$	(14,886	)	$	(15,601	)

7. Prepaid Expenses and Other Current Assets

Prepaids and other current assets as of March 31, 2012, and December 31, 2011, consisted of the following (in thousands):

	March 31, 2012		December 31, 2011
Survey participant incentives and prepaid postage	$	2,637	$	1,770
Prepaid income taxes		—		1,984
Prepaid Scarborough royalty		2,114		—
Insurance recovery receivables		399		993
Other		1,366		2,394
Prepaids and other current assets	$	6,516	$	7,141

Insurance recovery receivables. During 2008, the Company became involved in two securities-law civil actions and a governmental interaction primarily related to the commercialization of the Company’s PPM service. The management of the Company believes a portion of the legal fees and costs associated with this litigation are covered by the Company’s Directors and Officers insurance policy and therefore has recognized an insurance recovery receivable. On February 3, 2012, as a result of a mediation process overseen by an independent mediator, the Company and its insurers agreed to settle the class action for $7.0 million, which will be funded by insurance. From 2008 until March 31, 2012, the Company had incurred approximately $12.5 million in legal fees and costs in defense of its positions related thereto, and as of March 31, 2012, the Company had received $9.2 million in insurance reimbursements related to these legal actions. From 2008 until December 31, 2011, the Company had incurred approximately $12.1 million in legal fees and costs in defense of its positions related thereto, and as of December 31, 2011, the Company had received $7.9 million in insurance reimbursements.

For the three-month periods ended March 31, 2012, and 2011, the Company incurred approximately $0.4 million, and $0.4 million, respectively, in related legal fees, which were recognized as increases to selling, general, and administrative expense. These legal fees were offset by $0.7 million, and $0.4 million in estimated insurance recoveries, which were recognized as reductions to selling, general and administrative expense during 2012 and 2011, respectively.

8. Equity and Other Investments

The Company’s equity and other investments consisted of the following (in thousands):

	March 31, 2012		December 31, 2011
Scarborough	$	7,905	$	13,210

Equity and other investments	$	9,608	$	14,913

The Company’s 49.5% investment in Scarborough Research (“Scarborough”), a Delaware general partnership, is accounted for using the equity method of accounting. The Company’s preferred stock investment in TRA Global, Inc., (“TRA”), a Delaware corporation is accounted for using the cost method of accounting.

9. Contingencies

The Company has been involved in a number of governmental interactions primarily related to the commercialization of our PPM service. There was no liability for contingencies recorded on the balance sheet as of March 31, 2012. A contingent loss liability in the amount of $0.4 million for a claim was recorded in accrued expenses and other current liabilities on the Company’s consolidated balance sheet as of December 31, 2011. A $0.4 million settlement was paid by the Company during the first quarter ended March 31, 2012 related to this claim.

10. Retirement Plans

Certain of the Company’s United States employees participate in a defined-benefit pension plan that closed to new participants effective January 1, 1995. The Company has a nonqualified, unfunded supplemental retirement plan, as well as a postretirement healthcare plan for eligible retired employees who participate in the pension plan and were hired before January 1, 1992.

11. Acquisitions

Zokem Oy. On July 28, 2011, a wholly-owned subsidiary of the Company acquired Zokem Oy. The purchase price was $10.6 million in cash plus a contingent consideration arrangement with an estimated fair value of approximately $0.9 million as of the acquisition date. The contingent consideration arrangement provides for possible additional cash payments to be made by the Company to the former Zokem shareholders through 2015 of up to $12.0 million, which are contingent upon Zokem reaching certain financial performance targets in the future. The approximate $0.9 million fair value estimate was determined by applying the income approach method. The key assumptions used in the fair value valuation include a probability-weighted range of performance targets for the four-year measurement period of 2012 through 2015 and an adjusted discount rate. The Company periodically reassesses the fair value of the contingent consideration. As of March 31, 2012, the Company increased its estimate of the fair value of the contingent consideration from $1.0 million at December 31, 2011, to $1.1 million, which was recorded in other noncurrent liabilities on the Company’s consolidated balance sheet.

12. Goodwill

The following table shows the changes in goodwill for the three-month periods ended March 31, 2012, and 2011, (in thousands):

	Three Months Ended March 31, 2012		Three Months Ended March 31, 2011
Beginning balance,	$	45,430	$	38,895
Translation effect		197		—
Ending balance	$	45,627	$	38,895

13. Taxes

The effective tax rate decreased to 38.1% for the three-month period ended March 31, 2012, from 38.5% for the three-month period ended March 31, 2011. The decrease results primarily from the settlement of various audits during the three-month period ended March 31, 2012.

During the three-month period ended March 31, 2012, the Company’s unrecognized tax benefits for certain tax contingencies decreased from $1.3 million as of December 31, 2011, to $1.2 million as of March 31, 2012. The decrease is attributable to the settlement of various audits. If recognized, the $1.2 million in unrecognized tax benefits would reduce the Company’s effective tax rate in future periods.

Income taxes paid for the three-month periods ended March 31, 2012 and 2011, were $0.3 million and $0.8 million, respectively.

13

14. Share-Based Compensation

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

	Three-Month Periods Ended March 31,
	2012		2011
Cost of revenue	$	146	$	128
Selling, general and administrative		1,922		1,795
Research and development		100		82
Share-based compensation	$	2,168	$	2,005

No share-based compensation cost was capitalized during the three-month periods ended March 31, 2012, and 2011.

Stock Options

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

For the three-month periods ended March 31, 2012 and 2011, the number of stock options granted was 93,955 and 73,225, respectively, and the weighted-average exercise price for those stock options granted was $33.87 and $44.06, respectively.

As of March 31, 2012, there was $3.0 million in total unrecognized compensation cost related to unvested stock options. This aggregate unrecognized cost is expected to be recognized over a weighted-average remaining period of 2.2 years. The weighted-average exercise price and weighted-average remaining contractual term for outstanding stock options as of March 31, 2012, were $33.52 and 5.6 years, respectively.

Service and Performance Award Units

Service award units. The Company’s unvested 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. Compensation expense for service award units is recognized on a straight-line basis over the vesting period using the fair market value of the Company’s common stock on the date of grant.

As of March 31, 2012, there was $1.6 million of total unrecognized compensation cost related to unvested service award units. This aggregate unrecognized cost for service award units is expected to be recognized over a weighted-average period of 1.8 years.

Fair value of service award shares vested during the period	$	448	$	683

Performance award units. During the three-month periods ended March 31, 2012 and 2011, the Company granted performance award units under the 2008 Plan. These performance award units (i) were issued at the fair market value of the Company’s common stock on the date of grant, (ii) will expire without vesting if the Company’s return on invested capital (“ROIC”) for the annual performance period does not exceed 12%, which is an approximation of the Company’s weighted average cost of capital, (iii) will, if the Company’s ROIC exceeds 12%, vest in four equal annual installments beginning with 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.

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 March 31, 2012, there was $2.7 million of total unrecognized compensation cost related to unvested performance award units. This aggregate unrecognized cost is expected to be recognized over a weighted-average period of 3.1 years.

Deferred Stock Units

Service DSU grants to CEO. During the three-month periods ended March 31, 2012 and 2011, the Company granted service-based deferred stock unit awards (“Service DSUs”) under the 2008 Plan 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. Service DSUs also include dividend equivalent DSUs, which vest immediately upon the date of 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 three-month periods ended March 31, 2012, and 2011.

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 March 31, 2012, there was no unrecognized compensation cost related to Service DSUs.

Additional information for the three-month periods ended March 31, 2012, and 2011, is noted in the following table (dollars in thousands, except per share amounts):

Service DSU’s Granted to CEO	Three-Month Period Ended March 31, 2012		Three-Month Period Ended March 31, 2011

Weighted-average grant date fair value per share granted during the period	$	34.03	$	44.44
Fair value of shares vested during the period	$	572	$	704

Performance DSU grants to CEO. During the three-month periods ended March 31, 2012 and 2011, the Company granted performance-based deferred stock unit awards (“Performance DSUs”) under the 2008 Plan 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 ROIC for the annual performance period does not exceed 12%, which is an approximation of the Company’s weighted average cost of capital, (iii) will, if the Company’s ROIC exceeds 12%, 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 March 31, 2012, there was $2.1 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 .8 years.

Service DSU grants to Board of Directors (“Board”). The Company issues deferred stock units to its Board of Directors (“Board DSUs”) under the 2008 Plan. These Board DSUs (i) were issued at the fair market value of the Company’s common stock on the date of grant and (ii) if vested, will be convertible to shares of the Company’s common stock subsequent to termination of service as a director. The 2010 and 2011 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, Company stock, 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 March 31, 2012, there was $1.1 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 1.8 years.

15. Concentration Risk

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

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-Month Period Ended March 31, 2012			Three-Month Period Ended March 31, 2011
Quantitative radio audience ratings service and related software licensing revenue		96	%		96	%

The Company had one customer that individually represented approximately 19% of its annual revenue for the year ended December 31, 2011. The Company had two customers that individually represented approximately 22% and 12% of its total accounts receivable balance as of March 31, 2012, and two customers that individually represented approximately 23% and 11% of its total accounts receivable balance as of December 31, 2011. The Company has historically experienced a high level of contract renewals.

16. Stock Repurchases

On February 9, 2012, the Company’s Board of Directors authorized a program to repurchase up to $100.0 million in shares of the Company’s outstanding common stock through either periodic open-market or private transactions, in accordance with applicable insider trading and other securities laws and regulations, at then-prevailing market prices over a period of up to two years ending February 9, 2014. As of May 2, 2012, the Company had repurchased 956,091 shares of its outstanding common stock under this program for approximately $35.0 million.

17. Financial Instruments

The Company believes the fair market value of the TRA investment approximates its carrying value of $1.7 million as of March 31, 2012. The Company accounts for its $1.7 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. 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.

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

• 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

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

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, 2011, and elsewhere, and any subsequent periodic or current reports filed by us with the Securities and Exchange Commission (the “SEC”).

19

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

Overview

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

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

• estimating the size and composition of audiences to media other than radio, including mobile media, television viewed out-of-home, and content distributed on multiple platforms;

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

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

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

Historically, our quantitative radio ratings services and related software have accounted for a substantial majority of our revenue. For each of the three-month periods ended March 31, 2012, and 2011, our quantitative radio ratings services and related software accounted for approximately 96% of our revenue. Approximately 84% of our total revenue for the three-month period ended March 31, 2012, was derived from local radio ratings services, of which approximately 65% was from the PPM Markets and 35% was from our Diary markets.

We expect for the year ending December 31, 2012, our quantitative radio ratings services and related software licensing will account for approximately 89% of our revenue. We also expect approximately 78% of our total revenue for the year ending December 31, 2012 will be derived from local radio ratings services, of which we estimate approximately 74% will be from the PPM Markets and 26% will be from the Diary markets. Quarterly fluctuations in these percentages are reflective of the seasonal delivery schedule of our quantitative radio ratings service and our Scarborough reports. For further information regarding seasonality trends, see “Seasonality.”

While we expect our quantitative radio ratings services and related software licensing will 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 PPM ratings service and technology.

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

Ratings Trends and Initiatives for our Syndicated Radio Ratings Services

Challenges

We face a number of challenges in our syndicated 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 group participating in 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.

Quality Improvement Initiatives

In an effort to address the above 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 recruiting, targeted in-person recruiting, and address-based sampling. It is more expensive for us to recruit cell phone households and to conduct targeted in-person recruiting and address-based sampling. Because we intend to continue to increase the number of cell phone households in our samples and the level of address-based and targeted in-person recruiting, we expect the expenditures required to support these methods will be material. We currently anticipate the aggregate cost of cell phone household recruitment for the PPM and Diary services, and address-based and targeted in-person recruiting for the PPM service will be approximately $18.5 million in 2012, as compared to $15.5 million in 2011.

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

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

MRC Accreditation

In February 2012, the MRC revoked accreditation of the quarter-hour-based radio ratings data produced by the PPM ratings service in five local markets that had previously been accredited: Cleveland; Portland, OR; Riverside-San-Bernardino; Salt Lake City-Ogden-Provo; and Tampa-St. Petersburg-Clearwater. As of the date we filed this Quarterly Report on Form 10-Q with the SEC, the quarter-hour-based radio ratings data produced by the PPM ratings service is accredited by the MRC in nine local markets: Atlanta; Cincinnati; Houston-Galveston; Kansas City; Milwaukee-Racine; Minneapolis-St. Paul; Philadelphia; Phoenix; and St. Louis. We have applied for accreditation in all PPM Markets. We continue to seek accreditation in all unaccredited PPM Markets. For additional information regarding the status of MRC accreditation of our ratings services, see “Item 1. Business— Media Rating Council Accreditation” in our Annual Report on Form 10-K for the year ended December 31, 2011.

21

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. Complying with these laws may require us to make certain investments, make modifications to existing services, or prohibit us from offering certain types of services, any of which may be material and adversely impact our financial results. Failing to comply could result in civil and criminal liability, negative publicity, data being blocked from use, and liability under contracts with our customers, vendors, and partners.

Stock Repurchases

On February 9, 2012, our Board of Directors authorized a program to repurchase up to $100.0 million in shares of our outstanding common stock through either periodic open-market or private transactions, in accordance with applicable insider trading and other securities laws and regulations, at then-prevailing market prices over a period of up to two years ending February 9, 2014. As of May 2, 2012, we have repurchased 956,091 shares of outstanding common stock under this program for approximately $35.0 million.

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 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 2011, Clear Channel represented approximately 19% of our total revenue. Additionally, although the amount of revenue associated with customer contracts expiring in 2012 is lower, 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 March 31, 2012, and December 31, 2011, our capitalized software developed for internal use had carrying amounts of $28.6 million and $28.9 million, respectively, including $10.1 million and $10.4 million, respectively, of software related to the PPM service.

22

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

We include, in our tax calculation methodology, an assessment of the uncertainty in income taxes by establishing recognition thresholds for our tax positions. Inherent in our calculation are critical judgments by management related to the determination of the basis for our tax positions. For further information regarding our unrecognized tax benefits, see Note 13 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 total of $12.5 million in legal fees and expenses in connection with these matters. As of March 31, 2012, an aggregate of $9.2 million in insurance reimbursements related to these legal actions has been received. As of March 31, 2012, and December 31, 2011, our insurance claims receivable related to these legal actions was $0.4 million and $1.0 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 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. In the event the fair value of the investment in TRA were to fall below its carrying value in the future, we would be required to recognize an impairment loss. As of March 31, 2012, the carrying value of our investment in TRA was $1.7 million.

Contingent consideration. The agreement governing the 2011 acquisition of Zokem Oy, now Arbitron Mobile Oy (“Arbitron Mobile”), provides for possible additional cash payments to be made by us to the former Zokem shareholders through 2015 of up to $12.0 million, contingent upon Arbitron Mobile reaching certain financial performance targets in the future. We estimated the fair value of this contingent consideration to be approximately $0.9 million as of the July 28, 2011 acquisition date. We periodically estimate the fair value of the contingent consideration and any change in fair value will be recognized in our consolidated financial results of operations. An increase in the contingent consideration expected to be paid will result in a charge to operations in the quarter the anticipated fair value of contingent consideration increases, while a decrease in the contingent consideration expected to be paid will result in a credit to operations in the quarter the anticipated fair value of contingent consideration decreases. The estimate of the fair value of contingent consideration requires subjective assumptions to be made of future operating results. We estimated that the fair value of the contingent consideration as of March 31, 2012 to be $1.1 million, an increase of $0.1 million since December 31, 2011. Future revisions to our assumptions could materially change our estimate of the fair value of contingent consideration and therefore materially affect our future financial results and financial condition.

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

24

Revenue. Revenue increased by 5.5% or $5.5 million for the three-month period ended March 31, 2012, as compared to the same period in 2011. PPM-based ratings service revenue increased by $5.5 million primarily due to contracted price increases in all PPM Markets.

Cost of Revenue. Cost of revenue increased by 3.9% or $1.8 million for the three-month period ended March 31, 2012, as compared to the same period in 2011. Cost of revenue increased primarily due to a $1.0 million increase in aggregate costs associated with address based sampling, in-person recruiting and cell-phone household recruiting. Cost of revenue also increased by $0.8 million during the three-month period ended March 31, 2012, as compared to the same period in 2011, due to incremental costs associated with our cross platform initiatives, as well as costs incurred related to Arbitron Mobile, which was acquired in July 2011.

Selling, General, and Administrative. Selling, general, and administrative increased by 5.2% or $0.9 million for the three-month period ended March 31, 2012, as compared to the same period in 2011. Selling, general, and administrative increased primarily due to $1.2 million in Arbitron Mobile-related costs incurred during the three-month period ended March 31, 2012, versus none in the same period in 2011.

Research and Development. Research and development increased by 8.0% or $0.7 million for the three-month period ended March 31, 2012, as compared to the same period in 2011. Research and development increased primarily due to a $0.5 million increase in engineering development expense for the three-month period ended March 31, 2012, as compared to the same period in 2011.

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

EBIT and EBITDA increased by $2.3 million and $2.7 million, respectively, for the three-month period ended March 31, 2012, as compared to the same period in 2011, primarily due to an increase in PPM service revenue.

Liquidity and Capital Resources

	As of March  31, 2012		As of December  31, 2011		Change
Cash and cash equivalents	$	36,185	$	19,715	$	16,470
Working capital	$	22,923	$	16,250	$	6,673
Working capital, excluding deferred revenue which does not require a significant additional cash outlay	$	61,060	$	53,330	$	7,730
Total debt	$	—	$	—	$	—

We have relied upon our cash flow from operations, supplemented by borrowings under our available revolving credit facility as needed, to fund our dividends, common stock repurchases, capital expenditures, and contractual obligations. We expect, based on current and anticipated levels of operating performance, our cash flow from operations, cash and cash equivalents, and availability under our Credit Facility will be sufficient to support our operations for the next 12 to 24 months. See “— Credit Facility” for further discussion of the relevant terms and covenants.

Cash flow from operating activities. For the three-month period ended March 31, 2012, the net cash provided by operating activities was $40.2 million, which was primarily due to $36.6 million of EBITDA, which 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 three-month period ended March 31, 2012, was positively impacted by a $11.2 million increase in accrued taxes, which typically are significantly higher at the end of the first quarter as compared to the subsequent year end balance due to the timing of tax payments scheduled for later in the year. In addition, net cash from operations was positively impacted by a $11.1 million decrease in accounts receivable due to higher collections. These increases in net cash provided by operating activities were partially offset by a $10.4 million decrease in payroll, bonus, and benefit accruals for the first quarter of 2012 and a $7.2 million decrease in accrued Scarborough royalties.

Cash flow from investing activities. Net cash used in investing activities for the three-month periods ended March 31, 2012, and 2011, was $4.9 million and $7.2 million, respectively. This $2.3 million decrease in cash used in investing activities was due primarily to a $1.8 million decrease in metering equipment and other PPM-related capital expenditures for the three-month period ended March 31, 2012, as compared to the same period in 2011.

Cash flow from financing activities. Net cash used in financing activities for the three-month periods ended March 31, 2012, and 2011, was $18.8 million and $26.2 million, respectively. This $7.4 million decrease in net cash used in financing activities was due primarily to $25.0 million of net repayments made during the first quarter of 2011 of our then outstanding obligations under our prior credit facility. During the three-month period ended March 31, 2012, we had no outstanding borrowings or repayments under our current Credit Facility. This decrease was partially offset by $17.3 million of repurchases of our common stock during the three-month period ended March 31, 2012. We made no repurchases of our common stock during 2011.

Repatriation of Foreign Earnings

We have provided for U.S. taxes on all of our foreign earnings, consistent with the U.S. Internal Revenue Code’s taxation of world-wide income. We do not have material amounts of unrepatriated earnings in foreign jurisdictions and do not expect to permanently reinvest these current or future foreign earnings outside of the U.S.

26

Credit Facility

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

Our Credit Facility contains financial terms, covenants and operating restrictions that potentially restrict our financial flexibility. The material debt covenants under our Credit Facility include both a maximum leverage ratio and a minimum interest coverage ratio. The leverage ratio is a non-GAAP financial measure equal to the amount of our consolidated total indebtedness, as defined in our Credit Facility, divided by a contractually defined adjusted Earnings Before Interest, Taxes, Depreciation and Amortization and non- cash compensation (“Consolidated EBITDA”) for the trailing four-quarter period. The interest coverage ratio is a non-GAAP financial measure equal to Consolidated EBITDA divided by total interest expense. Both ratios are designed as measures of our ability to meet current and future debt obligations. The following table presents the actual ratios and their threshold limits as defined by the Credit Facility as of March 31, 2012:

Covenant	Threshold		Actual
Maximum leverage ratio		3.25		0.00
Minimum interest coverage ratio		3.00		246.0

As of March 31, 2012, based upon these financial covenants, there was no default or limit on our ability to borrow the unused portion of our Credit Facility.

Our Credit Facility contains customary events of default, including nonpayment and breach covenants. In the event of default, repayment of borrowings under the Credit Facility could be accelerated. Our Credit Facility also contains cross default provisions whereby a default on any material indebtedness, as defined in the Credit Facility, could result in the acceleration of our outstanding debt and the termination of any unused commitment under the Credit Facility. The agreement potentially limits, among other things, our ability to sell assets, incur additional indebtedness, and grant or incur liens on our assets. Under the terms of the Credit Facility, all of our material domestic subsidiaries, if any, must guarantee the commitment. Currently, we do not have any material domestic subsidiaries as defined under the terms of the Credit Facility. Although we do not believe the terms of our Credit Facility limit the operation of our business in any material respect, the terms of the Credit Facility may restrict or prohibit our ability to raise additional debt when needed or could prevent us from investing in other growth initiatives. We have been in compliance with the terms of the Credit Facility since the inception of the agreement. As of May 2, 2012, we had no outstanding borrowings under the Credit Facility.

27

Seasonality

Revenue

We recognize revenue for services over the term of license agreements as services are delivered while expenses are recognized as incurred. As of Spring 2012, we gather radio-listening data in 277 U.S. local markets, including 229 Diary markets and 48 PPM Markets.

In PPM Markets, we deliver ratings 13 times per year, with four PPM ratings reports delivered in the fourth quarter of a given year. 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.

All 229 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, consolidated revenue is typically highest in the fourth quarter and lowest in the second quarter of each year.

Costs and expenses

Now that all our planned PPM Markets are commercialized, and because we conduct our PPM services continuously throughout the year, we do not expect significant seasonality in PPM costs and expenses. In our Diary service, our expenses are generally higher in the second and fourth quarters as we conduct the Spring and Fall Surveys for all 229 of our Diary Markets.

Equity earnings/losses in Scarborough Research

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

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

In November 2011, we entered into our Credit Facility with a consortium of lenders to provide us up to $150.0 million of financing. Interest on borrowings under the Credit Facility is calculated based on a floating rate for a duration of up to six months, at which time the interest rate is reset based upon the LIBOR. As of March 31, 2012, we had no outstanding borrowings under the Credit Facility. Therefore, a hypothetical market interest rate change of 1% would have zero impact on our results of operations over a 12-month period. A hypothetical market interest rate change of 1% would have no impact on either the carrying amount or the fair value of the Credit Facility. We do not use derivatives for speculative or trading purposes.

Foreign Currency Risk

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

As of March 31, 2012, we have $4.8 million in recorded intercompany balances on our Finnish and Indian subsidiary balance sheets, which are impacted by fluctuations in currency exchange rates. As the exchange rates increase or decrease, our intercompany balances will be exposed to translation adjustment charges and/or credits, which will be recognized in our financial results.

Financial statements of foreign subsidiaries are translated into United States dollars at current rates at the end of the period except that revenue and expenses are translated at average current exchange rates during each reporting period. The translation adjustments are recorded in accumulated other comprehensive income (loss) on our consolidated balance sheet until the net investment in such foreign subsidiaries is liquidated. As of March 31, 2012, the cumulative net currency translation adjustment recorded on our balance sheet reduced our shareholders’ equity by $1.8 million.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

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

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarterly period ended March 31, 2012, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

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

On 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 and 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 sought 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. On February 3, 2012, as a result of a mediation process overseen by an independent mediator, the Company and its insurers agreed to settle the case for $7 million, which will be funded by insurance. Because this is a class action, settlements of this type are subject to preliminary and final review by the Court with an opportunity for class members to respond to the proposed settlement and object if they so desire. That process typically takes 4-5 months and has not yet begun.

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.

On March 21, 2012, the State of California brought a lawsuit against Arbitron in the Superior Court of the State of California, County of San Francisco. The lawsuit alleged that Arbitron violated California unfair competition, false advertising and civil rights laws when it commercialized its PPM ratings service in California. On March 26, 2012, Arbitron entered into a stipulated judgment with the Attorney General of California and the City Attorneys of Los Angeles and San Francisco in which it agreed to continue a number of measures that are already an integral part of the PPM ratings service in California markets and to pay a total of $400,000 in settlement of all claims brought in the lawsuit. In agreeing to the entry of the stipulated judgment, Arbitron denied all allegations of wrongdoing and liability alleged in the complaint.

30

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.

Item 1A. Risk Factors

See “Item 1A. — Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011 for a detailed discussion of risk factors affecting Arbitron.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On February 9, 2012, our Board of Directors authorized a program to repurchase up to $100.0 million in shares of our outstanding common stock through either periodic open-market or private transactions, in accordance with applicable insider trading and other securities laws and regulations, at then-prevailing market prices over a period of up to two years ending February 9, 2014. The following table outlines the stock repurchase activity during the three months ended March 31, 2012:

Arbitron Purchases of Equity Securities

Period	Total Number of Shares Purchased		Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Program		Total Dollar Value of Shares Purchased			Maximum Dollar Value of Shares That May Yet Be Purchased Under the Program

ARBITRON INC.

2008 EQUITY COMPENSATION PLAN

PERFORMANCE-BASED DEFERRED STOCK UNIT AGREEMENT

To William T. Kerr:

Arbitron Inc. (the “Company”) has granted you (the “Grant”) deferred stock units as set forth on Exhibit A to this Agreement (the “DSUs”) under its 2008 Equity Compensation Plan (the “Plan”), subject to the Vesting Schedule and requirements specified on Exhibit A.

The Grant is subject in all respects to the applicable provisions of the Plan. This Agreement does not cover all of the rules that apply to the Grant under the Plan, and the Plan defines any capitalized terms in this Agreement that this Agreement does not define.

In addition to the Plan’s terms and restrictions, the following terms and restrictions apply:

Vesting Schedule	The Grant becomes nonforfeitable (“Vested”) as to some or all of the DSUs only as provided on Exhibit A.
Distribution	You will receive a distribution of shares (the “Shares”) of Company common stock (“Common Stock”) equivalent to your DSUs as follows:
	One-quarter of the initial DSUs within 45 days following each anniversary of the Date of Grant, provided that (i) no DSUs will be paid before they vest, (ii) no DSUs will be paid until 30 days after you have a separation from service, except as the Plan may otherwise require, and (iii) all DSUs will be distributed within 30 days after and if your employment ends as a result of your death or Disability (as the latter is defined in your Amended and Restated Executive Employment Agreement with the Company dated February 8, 2011 (the “Employment Agreement”)), provided that the Disability will only accelerate the payment schedule if it also satisfies the definition of Disability under Section 409A of the Code.
	Each date on which you receive a distribution of Shares pursuant to the foregoing is referred to as a “Distribution Date.”
Limited Status	You understand and agree that the Company will not consider you a shareholder for any purpose with respect to the Shares, unless and until the Shares have been issued to you on the Distribution Date(s). You will, however, receive dividend equivalents (“Dividend Equivalent Rights”) with respect to the Vested DSUs, measured using the Shares they represent, with the amounts convertible into full or fractional additional Vested DSUs based on dividing the dividends by the Fair Market Value (as defined in the Plan) as of the date of dividend distribution and holding the resulting additional Vested DSUs for distribution as provided for the DSUs with respect to which they were issued.
Voting	DSUs cannot be voted. You may not vote the Shares unless and until the Shares are distributed to you.

Transfer Restrictions and Forfeiture	Except as otherwise provided in this paragraph, you may not sell, assign, pledge, encumber, or otherwise transfer any interest (“Transfer”) in the Shares until the Shares are distributed to you. Notwithstanding the foregoing, the DSUs (or a portion thereof) may be transferred pursuant to a gratuitous transfer by you to or for the benefit of any immediately family member or family trust if, with respect to such proposed transferee, the Company would be eligible to use a Form S-8 for the registration of the sale of the Shares under the Securities Act of 1933, as amended. In connection with such gratuitous transfer, the Company may condition such transfer upon the receipt from you and such permitted transferee of a written instrument in form and substance satisfactory to the Company confirming that such transferee will be bound by all of the terms and conditions of the DSUs and, in the event the Company does not require such an agreement, the transferee will nonetheless be subject to the terms and conditions of the DSUs. Any other attempted Transfer that precedes the Distribution Date for such Shares is invalid.
	Unless the Administrator determines otherwise at any time or Exhibit A provides otherwise, if your service with the Company terminates for any reason before all of your DSUs are Vested, then you will forfeit such unvested DSUs (and the Shares to which they relate) to the extent that such DSUs do not otherwise vest as a result of the termination. The forfeited DSUs will then immediately revert to the Company. You will receive no payment for DSUs that you forfeit.
Additional Conditions to Receipt	The Company may postpone issuing and delivering any Shares for so long as the Company determines to be advisable to satisfy the following:
	its completing or amending any securities registration or qualification of the Shares or its or your satisfying any exemption from registration under any Federal or state law, rule, or regulation;
	its receiving proof it considers satisfactory that a person or entity seeking to receive the Shares after your death is entitled to do so;
	your complying with any requests for representations under the Grant and the Plan; and
	its or your complying with any federal, state, or local tax withholding obligations.
Taxes and Withholding	The DSUs provide tax deferral, meaning that they are not taxable to you for income tax purposes until you actually receive Shares on or around each Distribution Date. You will then owe taxes at ordinary income tax rates as of each Distribution Date at the Shares’ value.
	The Company is required to withhold (in cash from salary or other amounts owed you) the applicable percentage of the value of the Shares on the Distribution Date, regardless of whether you sell them. If the Company does not choose to do so, you agree to arrange for payment of the withholding taxes and/or confirm that the Company is arranging for appropriate withholding. You will be subject to Social Security and Medicare taxation as you vest in the DSUs, and the preceding provisions will apply to those taxes as though the vesting date were a Distribution Date.
Additional	If you receive Shares at a time when the Company does not have a current registration

- 2 -

Representations from You	statement (generally on Form S-8) under the Act that covers issuances of Shares to you, you must comply with the following before the Company will release the Shares to you.
	You must:
	represent to the Company, in a manner satisfactory to the Company’s counsel, that you are acquiring the Shares for your own account and not with a view to reselling or distributing the Shares; and
	agree that you will not sell, transfer, or otherwise dispose of the Shares unless:
	a registration statement under the Act is effective at the time of disposition with respect to the Shares you propose to sell, transfer, or otherwise dispose of; or
	the Company has received an opinion of counsel or other information and representations it considers satisfactory to the effect that, because of Rule 144 under the Act or otherwise, no registration under the Act is required.
Additional Restriction	You will not receive the Shares if issuing the Shares would violate any applicable federal or state securities laws or other laws or regulations.
No Effect on Employment or Other Relationship	Nothing in this Agreement restricts the Company’s rights or those of any of its affiliates to terminate your employment or other relationship at any time, with or without cause. The termination of your relationship, whether by the Company or any of its affiliates or otherwise, and regardless of the reason for such termination, has the consequences provided for under the Plan and any applicable employment or severance agreement or plan.
No Effect on Running Business	You understand and agree that the existence of the DSU 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.
Section 409A	This Agreement is intended to comply with the requirements of Section 409A of the Internal Revenue Code and must be construed consistently with that section. Notwithstanding anything in the Plan or this Agreement to the contrary, if the Vested portion is increased in connection with your “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to death, and if (x) you are then a “specified employee” within the meaning of Section 409A at the time of such separation from service (as determined by the Company, by which determination you agree you are bound) and (y) the payment under such accelerated DSUs will result in the imposition of additional tax under Section 409A if paid to you within the six month period following your separation from service, then the payment under such accelerated DSUs will not be made until the earlier of (i) the date six months and one day following the date of your separation from service or (ii) the 10th day after your date of death, and will be paid within 10 days thereafter. Neither the Company nor you shall have the right to accelerate or defer the delivery of any such payments or

- 3 -

	benefits except to the extent specifically permitted or required by Section 409A. In any event, the Company makes no representations or warranty and shall have no liability to you or any other person, if any provisions of or payments under this Agreement are determined to constitute deferred compensation subject to Code Section 409A but not to satisfy the conditions of that section.
Unsecured Creditor	This Agreement creates a contractual obligation on the part of the Company to make payment under the DSUs credited to your account at the time provided for in this Agreement. Neither you nor any other party claiming an interest in deferred compensation hereunder shall have any interest whatsoever in any specific assets of the Company. Your right to receive payments hereunder is that of an unsecured general creditor of Company.
Governing Law	The laws of the State of Delaware will govern all matters relating to this Agreement, without regard to the principles of conflict of laws.
Notices	Any notice you give to the Company must follow the procedures then in effect. If no other procedures apply, you must send your notice in writing by hand or by mail to the office of the Company's Secretary. If mailed, you should address it to the Company's Secretary at the Company's then corporate headquarters, unless the Company directs participants to send notices to another corporate department or to a third party administrator or specifies another method of transmitting notice. The Company and the Administrator will address any notices to you at your office or home address as reflected on the Company's personnel or other business records. You and the Company may change the address for notice by like notice to the other, and the Company can also change the address for notice by general announcements to participants.
Plan Governs	Wherever a conflict may arise between the terms of this Agreement and the terms of the Plan, the terms of the Plan will control.

DSUs: Date of Grant:

Vesting Schedule
Performance Condition	The Grant will expire without Vesting if the one-year performance goal (the “Performance Goal”) is not satisfied by the first anniversary of the Date of Grant. The Compensation Committee will have the full and sole discretion to determine whether the Company has met the Performance Goal and how each of its components is calculated. The Performance Goal is specified on Schedule I to this Exhibit A.
Service Condition	If the Performance Goal is met, the Grant is Vested as to one-fourth of the DSUs on each of the four one year anniversaries of the Date of Grant (each a “Vesting Date”), assuming you remain an individual service provider to the Company through those dates.
Special Acceleration	If your employment with the Company and all Subsidiaries ends by death or Disability, the DSUs will vest in full.
	If your employment ends on a termination without Cause or Retirement (each as determined under Section 6(b) of the Employment Agreement and as defined in Section 6(e) thereof) and the Performance Goal is met, any unvested portions of the DSUs will be treated as fully vested and will continue to be paid out according to the schedule in Distributions in the Grant agreement.
	If your employment ends with your resignation other than under a Retirement, you will immediately forfeit any unvested DSUs and the Shares to which they relate and any vested DSUs will continue to be paid out according to the schedule in Distributions in the Grant Agreement.
	If your employment ends on a termination by the Company for Cause, you will immediately forfeit all DSUs and the Shares to which they relate.

	Any acceleration of vesting under this Employment Termination section is subject, as applicable, to Section 4(c)(iii)(e) of the Employment Agreement and to the release requirement of Section 6(d) of the Employment Agreement.
Change in Control	If a Change in Control Event (as defined in the Plan) occurs before the first anniversary of the Date of Grant, the Performance Goal will be deemed to have been met.
	If a Change in Control Event (as defined in the Plan) occurs before the final Distribution Date and the Change in Control Event also would be an event described in Treas. Reg. Section 1.409A-3(i)(5), any unvested DSUs you then hold will fully Vest. A Change in Control Event that does not comport with that regulation will not cause full Vesting unless otherwise permitted by Section 409A. The payment will be in cash (unless the Board determines otherwise) equal to the value per share of the consideration received in the Change in Control Event multiplied by the number of DSUs, at which point the DSUs will expire without further obligation to you. The Board will have the authority to value any consideration received in the Change in Control Event to the extent neither cash nor readily marketable securities.

2008 EQUITY COMPENSATION PLAN

DEFERRED STOCK UNIT AGREEMENT – VESTED CEO GRANT

To William T. Kerr:

Arbitron Inc. (the “Company”) has granted you (the “Grant”) deferred stock units (“DSUs”) as set forth on Exhibit A to this Agreement under its 2008 Equity Compensation Plan (the “Plan”).

The Grant is subject in all respects to the applicable provisions of the Plan. This Agreement does not cover all of the rules that apply to the Grant under the Plan, and the Plan defines any capitalized terms in this Agreement that this Agreement does not define.

In addition to the Plan’s terms and restrictions, the following terms and restrictions apply:

Vesting Schedule	The Grant is fully nonforfeitable (“Vested”) on the Grant Date.
Distribution Date	You will receive a distribution of shares (the “Shares”) of Company common stock (“Common Stock”) equivalent to your DSUs as soon as practicable following the date indicated on Exhibit A, the “Distribution Date,” subject to any overriding provisions in the Plan.
Limited Status	You understand and agree that the Company will not consider you a shareholder for any purpose with respect to the Shares, unless and until the Shares have been issued to you on the Distribution Date. You will, however, receive dividend equivalents (“Dividend Equivalent Rights”) with respect to the DSUs, measured using the Shares they represent, with the amounts convertible into full or fractional additional DSUs based on dividing the dividends by the Fair Market Value (as defined in the Plan) as of the date of dividend distribution and holding the resulting additional DSUs for distribution as provided for the other DSUs.
Voting	DSUs cannot be voted. You may not vote the Shares unless and until the Shares are distributed to you.
Transfer Restrictions	Except as otherwise provided in this paragraph, you may not sell, assign, pledge, encumber, or otherwise transfer any interest (“Transfer”) in the Shares until the Shares are distributed to you. Notwithstanding the foregoing, the DSUs (or a portion thereof) may be transferred pursuant to a gratuitous transfer by you to or for the benefit of any immediately family member or family trust if, with respect to such proposed transferee, the Company would be eligible to use a Form S-8 for the registration of the sale of the Shares under the Securities Act of 1933, as amended. In connection with such gratuitous transfer, the Company may condition such transfer upon the receipt from you and such permitted transferee of a written instrument in form and substance satisfactory to the Company confirming that such transferee will be bound by all of the terms and conditions of the DSUs and, in the event the Company does not require such an agreement, the transferee will nonetheless be subject to the terms and conditions of the DSUs. Any other attempted Transfer that precedes the Distribution Date for such Shares is invalid.

Additional Conditions to Receipt	The Company may postpone issuing and delivering any Shares for so long as the Company determines to be advisable to satisfy the following:
	its completing or amending any securities registration or qualification of the Shares or its or your satisfying any exemption from registration under any Federal or state law, rule, or regulation;
	its receiving proof it considers satisfactory that a person or entity seeking to receive the Shares after your death is entitled to do so;
	your complying with any requests for representations under the Grant and the Plan; and
	its or your complying with any federal, state, or local tax withholding obligations.
Taxes and Withholding	The DSUs provide tax deferral, meaning that they are not taxable to you for income tax purposes until you actually receive Shares on or around the Distribution Date. You will then owe taxes at ordinary income tax rates as of the Distribution Date at the Shares’ value.
	The Company will be required to withhold (in cash from salary or other amounts owed you) the applicable percentage of the value of the Shares on the Distribution Date. If the Company does not choose to do so, you agree to arrange for payment of the withholding taxes and/or confirm that the Company is arranging for appropriate withholding.
Additional Representations from You	If you receive Shares at a time when the Company does not have a current registration statement (generally on Form S-8) under the Act that covers issuance of Shares to you, you must comply with the following before the Company will release the Shares to you. You must:
	represent to the Company, in a manner satisfactory to the Company’s counsel, that you are acquiring the Shares for your own account and not with a view to reselling or distributing the Shares; and
	agree that you will not sell, transfer, or otherwise dispose of the Shares unless:
	a registration statement under the Act is effective at the time of disposition with respect to the Shares you propose to sell, transfer, or otherwise dispose of; or
	the Company has received an opinion of counsel or other information and representations it considers satisfactory to the effect that, because of Rule 144 under the Act or otherwise, no registration under the Act is required.
Additional Restriction	You will not receive the Shares if issuing the Shares would violate any applicable federal or state securities laws or other laws or regulations.

No Effect on Service Providing Relationship	Nothing in this Agreement restricts the Company’s rights or those of any of its affiliates to terminate your employment, service on the Company’s Board of Directors or other relationship at any time, with or without cause. The termination of your relationship, whether by the Company or any of its affiliates or otherwise, and regardless of the reason for such termination, has the consequences provided for under the Plan and any applicable employment or severance agreement or plan.
No Effect on Running Business	You understand and agree that the existence of the DSU 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.
Section 409A	This Agreement is intended to comply with the requirements of Section 409A of the Internal Revenue Code and must be construed consistently with that section. Notwithstanding anything in the Plan or this Agreement to the contrary, if (x) you are a “specified employee” within the meaning of Section 409A at the time of your separation from service (as determined by the Company, by which determination you agree you are bound) and (y) the payment under the DSUs will result in the imposition of additional tax under Section 409A if paid to you within the six month period following your separation from service, then the payment under such DSUs will not be made until the earlier of (i) the date six months and one day following the date of your separation from service or (ii) the 10th day after your date of death, and will be paid within 10 days thereafter. Neither the Company nor you shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. In any event, the Company makes no representations or warranty and shall have no liability to you or any other person, if any provisions of or payments under this Agreement are determined to constitute deferred compensation subject to Code Section 409A but not to satisfy the conditions of that section.
Unsecured Creditor	This Agreement creates a contractual obligation on the part of the Company to make payment under the DSUs credited to your account at the time provided for in this Agreement. Neither you nor any other party claiming an interest in deferred compensation hereunder shall have any interest whatsoever in any specific assets of the Company. Your right to receive payments hereunder is that of an unsecured general creditor of Company.
Governing Law	The laws of the State of Delaware will govern all matters relating to this Agreement, without regard to the principles of conflict of laws.
Notices	Any notice you give to the Company must follow the procedures then in effect. If no other procedures apply, you must send your notice in writing by hand or by mail to the office of the Company’s Secretary. If mailed, you should address it to the Company’s Secretary at the Company’s then corporate headquarters, unless the Company directs participants to send notices to another corporate department or to a third party administrator or specifies another method of transmitting notice.

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. The adoption of this guidance had no impact on 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 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 will be applied prospectively. The adoption of this guidance had no impact on the Company's consolidated financial statements.

The Company believes the fair market value of the TRA investment approximates its carrying value of $1.7 million as of March 31, 2012. The Company accounts for its $1.7 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. 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.

Acquisitions

11. Acquisitions

Zokem Oy. On July 28, 2011, a wholly-owned subsidiary of the Company acquired Zokem Oy. The purchase price was $10.6 million in cash plus a contingent consideration arrangement with an estimated fair value of approximately $0.9 million as of the acquisition date. The contingent consideration arrangement provides for possible additional cash payments to be made by the Company to the former Zokem shareholders through 2015 of up to $12.0 million, which are contingent upon Zokem reaching certain financial performance targets in the future. The approximate $0.9 million fair value estimate was determined by applying the income approach method. The key assumptions used in the fair value valuation include a probability-weighted range of performance targets for the four-year measurement period of 2012 through 2015 and an adjusted discount rate. The Company periodically reassesses the fair value of the contingent consideration. As of March 31, 2012, the Company increased its estimate of the fair value of the contingent consideration from $1.0 million at December 31, 2011, to $1.1 million, which was recorded in other noncurrent liabilities on the Company's consolidated balance sheet.

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-month periods ended March 31, 2012 and 2011, are based on the Company's weighted-average shares of common stock and potentially dilutive securities outstanding. Potentially dilutive securities are calculated in accordance with the treasury stock method, which assumes the proceeds from the exercise of all stock options are used to repurchase the Company's common stock at the average market price for the period. As of March 31, 2012, and 2011, there were stock options to purchase 2,105,924 shares, and 2,057,790 shares of the Company's common stock outstanding, respectively, of which stock options to purchase 1,238,880 shares, and 686,876 shares of the Company's common stock, respectively, were excluded from the computation of the diluted net income per weighted-average common share, 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.

Insurance recovery receivables. During 2008, the Company became involved in two securities-law civil actions and a governmental interaction primarily related to the commercialization of the Company's PPM service. The management of the Company believes a portion of the legal fees and costs associated with this litigation are covered by the Company's Directors and Officers insurance policy and therefore has recognized an insurance recovery receivable. On February 3, 2012, as a result of a mediation process overseen by an independent mediator, the Company and its insurers agreed to settle the class action for $7.0 million, which will be funded by insurance. From 2008 until March 31, 2012, the Company had incurred approximately $12.5 million in legal fees and costs in defense of its positions related thereto, and as of March 31, 2012, the Company had received $9.2 million in insurance reimbursements related to these legal actions. From 2008 until December 31, 2011, the Company had incurred approximately $12.1 million in legal fees and costs in defense of its positions related thereto, and as of December 31, 2011, the Company had received $7.9 million in insurance reimbursements.

For the three-month periods ended March 31, 2012, and 2011, the Company incurred approximately $0.4 million, and $0.4 million, respectively, in related legal fees, which were recognized as increases to selling, general, and administrative expense. These legal fees were offset by $0.7 million, and $0.4 million in estimated insurance recoveries, which were recognized as reductions to selling, general and administrative expense during 2012 and 2011, respectively.

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

	Three-Month Periods Ended March 31,

Cost of revenue	$	146	$	128
Selling, general and administrative		1,922		1,795

Share-based compensation	$	2,168	$	2,005

No share-based compensation cost was capitalized during the three-month periods ended March 31, 2012, and 2011.

Stock Options

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

For the three-month periods ended March 31, 2012 and 2011, the number of stock options granted was 93,955 and 73,225, respectively, and the weighted-average exercise price for those stock options granted was $33.87 and $44.06, respectively.

As of March 31, 2012, there was $3.0 million in total unrecognized compensation cost related to unvested stock options. This aggregate unrecognized cost is expected to be recognized over a weighted-average remaining period of 2.2 years. The weighted-average exercise price and weighted-average remaining contractual term for outstanding stock options as of March 31, 2012, were $33.52 and 5.6 years, respectively.

Service and Performance Award Units

Service award units. The Company's unvested 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. Compensation expense for service award units is recognized on a straight-line basis over the vesting period using the fair market value of the Company's common stock on the date of grant.

As of March 31, 2012, there was $1.6 million of total unrecognized compensation cost related to unvested service award units. This aggregate unrecognized cost for service award units is expected to be recognized over a weighted-average period of 1.8 years.

Additional information for the three-month periods ended March 31, 2012, and 2011, is noted in the following table (dollars in thousands, except per share amounts):

	Three-Month Period Ended March 31, 2012		Three-Month Period Ended March 31, 2011
Number of service award shares granted during the period		—		18,434
Weighted average grant-date fair value per share granted during the period		—	$	42.72
Fair value of service award shares vested during the period	$	448	$	683

Performance award units. During the three-month periods ended March 31, 2012 and 2011, the Company granted performance award units under the 2008 Plan. These performance award units (i) were issued at the fair market value of the Company's common stock on the date of grant, (ii) will expire without vesting if the Company's return on invested capital ("ROIC") for the annual performance period does not exceed 12%, which is an approximation of the Company's weighted average cost of capital, (iii) will, if the Company's ROIC exceeds 12%, vest in four equal annual installments beginning with 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.

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 March 31, 2012, there was $2.7 million of total unrecognized compensation cost related to unvested performance award units. This aggregate unrecognized cost is expected to be recognized over a weighted-average period of 3.1 years.

Additional information for the three-month periods ended March 31, 2012, and 2011, is noted in the following table (dollars in thousands, except per share amounts):

	Three-Month Period Ended March 31, 2012		Three-Month Period Ended March 31, 2011

Deferred Stock Units

Service DSU grants to CEO. During the three-month periods ended March 31, 2012 and 2011, the Company granted service-based deferred stock unit awards ("Service DSUs") under the 2008 Plan 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. Service DSUs also include dividend equivalent DSUs, which vest immediately upon the date of 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 three-month periods ended March 31, 2012, and 2011.

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 March 31, 2012, there was no unrecognized compensation cost related to Service DSUs.

Additional information for the three-month periods ended March 31, 2012, and 2011, is noted in the following table (dollars in thousands, except per share amounts):

Service DSU's Granted to CEO	Three-Month Period Ended March 31, 2012		Three-Month Period Ended March 31, 2011

Performance DSU grants to CEO. During the three-month periods ended March 31, 2012 and 2011, the Company granted performance-based deferred stock unit awards ("Performance DSUs") under the 2008 Plan 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 ROIC for the annual performance period does not exceed 12%, which is an approximation of the Company's weighted average cost of capital, (iii) will, if the Company's ROIC exceeds 12%, 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 March 31, 2012, there was $2.1 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 .8 years.

Additional information for the three-month periods ended March 31, 2012, and 2011, is noted in the following table (dollars in thousands, except per share amounts):

Weighted-average grant date fair value per share granted during the period	$	33.87	$	44.44
Fair value of shares vested during the period	$	396	$	227

Service DSU grants to Board of Directors ("Board"). The Company issues deferred stock units to its Board of Directors ("Board DSUs") under the 2008 Plan. These Board DSUs (i) were issued at the fair market value of the Company's common stock on the date of grant and (ii) if vested, will be convertible to shares of the Company's common stock subsequent to termination of service as a director. The 2010 and 2011 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, Company stock, 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 March 31, 2012, there was $1.1 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 1.8 years.

On November 21, 2011, the Company terminated its credit facility agreement originally signed on December 20, 2006. Also, on November 21, 2011, the Company entered into a new agreement with a consortium of lenders to provide up to $150.0 million of financing to the Company through a five-year, unsecured revolving credit facility (the "Credit Facility") expiring on November 21, 2016. The agreement contains an expansion feature to increase the total financing available under the Credit Facility by up to $75.0 million to an aggregate of $225.0 million. Such increased financing would be provided by one or more existing Credit Facility lending institutions, subject to the approval of the lending banks, and/or in combination with one or more new lending institutions, subject to the approval of the Credit Facility's administrative agent.

13. Taxes

The effective tax rate decreased to 38.1% for the three-month period ended March 31, 2012, from 38.5% for the three-month period ended March 31, 2011. The decrease results primarily from the settlement of various audits during the three-month period ended March 31, 2012.

During the three-month period ended March 31, 2012, the Company's unrecognized tax benefits for certain tax contingencies decreased from $1.3 million as of December 31, 2011, to $1.2 million as of March 31, 2012. The decrease is attributable to the settlement of various audits. If recognized, the $1.2 million in unrecognized tax benefits would reduce the Company's effective tax rate in future periods.

Income taxes paid for the three-month periods ended March 31, 2012 and 2011, were $0.3 million and $0.8 million, respectively.
