POST-EFFECTIVE AMENDMENT NO. 1

TERMINATION OF REGISTRATION STATEMENT AND

DEREGISTRATION OF SECURITIES

Prior to March 30, 2001, Ceridian Corporation was a publicly traded company whose principal lines of business were the human resource service businesses, the Comdata business, which provided transaction processing and regulatory compliance services for the transportation industry, and the radio audience measurement business. On March 30, 2001, Arbitron Inc.’s (“Arbitron”) predecessor, Ceridian Corporation, completed a spin-off of its lines of business other than its radio audience measurement business to a newly formed company named “New Ceridian” and changed its name from Ceridian Corporation to Arbitron Inc.

The purpose of this Post-Effective Amendment No. 1 to Form S-8, Registration Statement No. 333-58145 for the Ceridian Corporation Savings-Related Share Option Plan (the “Plan”), is to deregister shares registered for issuance pursuant to the Plan. The Form S-8, which was filed with the Securities and Exchange Commission (the “Commission”) on June 30, 1998, registered 500,000 shares of common stock for issuance pursuant to the Plan. Because no new awards of stock options can be made under the Plan, and because all of the stock options which were granted under the Plan and for which the related shares of common stock were registered on Registration Statement No. 333-58145 either have been exercised in full or have expired due to the passage of time, no additional shares of common stock registered on Registration Statement No. 333-58145 can be purchased or otherwise issued under the Plan. As a result, Arbitron hereby removes from registration any and all shares of common stock that were previously registered under Registration Statement No. 333-58145 and that remain unissued as of the date hereof, and hereby files this Post-Effective Amendment No. 1 to effect such removal and to terminate Registration Statement No. 333-58145.

As there are no securities being registered in this amendment, and the sole purpose of the amendment is to deregister securities, the disclosure requirements under the Securities Act of 1933 and the requirement for exhibits under Regulation S-K are inapplicable to this filing.
