For Immediate Release

ARBITRON INC. REPORTS 2002 FOURTH QUARTER AND YEAR END
FINANCIAL RESULTS

Annual revenue up 9.8%; Net income up 17.3% over 2001
Net income per share increases 14.5%

NEW YORK, January 23, 2002 – Arbitron Inc. (NYSE: ARB) today announced results for the quarter and year ended December 31, 2002.

For the fourth quarter 2002, the Company reported revenue of $57.8 million, an increase of 12.3% over revenue of $51.4 million during the fourth quarter of 2001. Earnings before interest and taxes (EBIT) for the quarter were $14.1 million, compared with EBIT of $9.3 million during the comparable period last year. Net income for the quarter was $6.5 million, compared with $2.6 million for the fourth quarter of 2001.

Cost and expenses for the quarter increased by 4.0%, from $46.0 million in 2001 to $47.9 million in 2002. Interest expense declined $1.4 million from 2001 as a result of significant reductions in debt between the two periods.

Net income per share for the quarter increased to $0.21 (diluted), compared with $0.09 (diluted) during the comparable period last year. Effective January 1, 2002, the Company discontinued the amortization of goodwill in accordance with generally accepted accounting principles. Had the company been required to adopt this accounting treatment effective as of January 1, 2001, net income and net income per share (diluted) for the three months ended December 31, 2001 would have been $3.0 million and $0.10, respectively.

For the year ended December 31, 2002, revenue was $249.8 million, an increase of 9.8% over the $227.5 million reported for the same period last year. EBIT was $85.7 million, compared to $75.5 million in 2001, an increase of 13.5% for the year. Net income for the year was $42.8 million or $1.42 per share (diluted), compared with $36.5 million, or $1.24 per share (diluted), last year. Had the discontinuation of amortization of goodwill been in effect in 2001, net income and net income per share (diluted) for the year ended December 31, 2001 would have been $38.2 million and $1.29, respectively.

Commenting on the results for the fourth quarter, Stephen Morris, president and chief executive officer of Arbitron, said, “We ended 2002 by meeting our financial goals for revenue and profitability, a good performance in a difficult year for the media industry. Our basic ratings, Scarborough and software services all made good progress in the quarter.”

“In the fourth quarter, our RADAR network radio measurement service expanded its roster of clients while staying on track in its transition to a more efficient and more effective sampling system,” said Mr. Morris. “Our acquisition of a license to the Measurecast Webcast ratings technology, also in the fourth quarter, should allow us to maintain a leadership position in the webcast ratings arena while keeping a tighter grip on costs.”

“Working with Nielsen Media Research, we continue to make progress on the refinements to the Portable People Meter (PPM) that the U.S. ratings marketplace requested. And on our own, we have made solid progress marketing the PPM in the international arena and have broadened our exploration of new applications for this promising technology,” said Mr. Morris.

“Given our progress and the overall strength of the core ratings business, we believe Arbitron remains well positioned to deliver solid growth in revenue and profitability while making measured investments in markets with long-term growth potential,” Mr. Morris concluded.

Arbitron will host a conference call at 10:00 a.m. EST on January 23rd to discuss its fourth quarter and year-end results as well as financial guidance for 2003. The Company invites you to listen to the call at the following telephone number: 1-800-683-1535. The call will also be available live on the Internet at the following sites: www.arbitron.com, www.ccbn.com and www.streetevents.com

Effective January 1, 2002, the Company adopted the provisions of Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets,” which required the Company to discontinue the amortization of goodwill and rather test such assets for impairment on an annual basis. Had the Company been required to adopt the provisions of the pronouncement effective as of January 1, 2001, net income and diluted net income per share for the three months ended December 31, 2001 would have been $3,023 and $0.10, respectively. The Company did not have any goodwill impairment charges from the adoption of the new pronouncement during 2002.

(2)

EBITDA is presented as supplemental information that management of Arbitron believes may be useful to some investors in evaluating Arbitron because it is widely used as a measure of evaluating a company’s operating performance before interest expense, as well as to evaluate its operating cash flow. EBITDA is calculated by adding back net interest expense, income tax expense, depreciation and amortization to net income. EBITDA should not be considered a substitute either for net income, as an indicator of Arbitron’s operating performance, or for cash flow, as a measure of Arbitron’s liquidity. In addition, because EBITDA is not calculated identically by all companies, the presentation here may not be comparable to other similarly titled measures of other companies.

For the year ended December 31, 2001, the computations of pro forma net income per weighted average common share are based upon Ceridian’s weighted average common shares and potentially dilutive securities outstanding for the three months ended March 31, 2001, and Arbitron’s weighted average common shares and potentially dilutive securities thereafter. The diluted weighted average common shares amounts for the three months ended March 31, 2001 assume that all of Ceridian’s historical dilutive securities were converted into Arbitron securities.

(4) Prior to the spin-off from Ceridian Corporation, Arbitron distributed its earnings to Ceridian. Those distributions, together with a $250 million distribution made to Ceridian on the date of the spin-off, gave rise to the stockholders’ deficit. Proceeds from the issuance of long-term debt were used by Arbitron to make the $250 million distribution. During the third quarter of 2002, the Company finalized the amount of Federal income tax loss carryforwards available at the time of the reverse spin-off. This resulted in a higher NOL tax benefit to Arbitron of $10.7 million, which reduced cash taxes payable and reduced stockholders’ deficit. The Company is currently compiling similar information with respect to state net operating losses. Upon completion of the required analysis, the Company will record such benefit, if any, through an increase in deferred income taxes and a reduction in stockholders’ deficit. The benefit will not impact net income.
