  On December 20, 2006, Arbitron Inc. (the "Company") entered into a $150 million senior unsecured credit facility with JPMorgan Chase Bank, National Association as Administrative Agent, Citizens Bank of Pennsylvania as Documentation Agent, Citibank, N.A. and Wachovia Bank, National Association as Co-Syndication Agents, J.P. Morgan Securities Inc. as Sole Bookrunner and Sole Lead Arranger, and a syndicate of lenders from time to time party thereto.  The Credit Agreement expires on December 20, 2011.<br><br>The description of the Credit Agreement (the "Credit Agreement") set forth below is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which is attached as Exhibit 10.1 hereto and is incorporated by reference herein.  The Credit Agreement also provides access to up to an additional $50 million of financing through an expansion feature under which the aggregate commitment of the lenders may be increased up to $200 million, subject to the availability of additional commitments.  The credit facility includes a $15 million swing line commitment and a $15 million commitment for issuance of letters of credit.<br><br>Borrowings under the credit facility bear interest at one of the two following rates, at the Company&#x2019;s option: (1) the Alternate Base Rate (the "ABR") plus the Applicable Rate, or (2) the Adjusted LIBO Rate plus the Applicable Rate; provided that all Swing Line Loans (as defined in the Credit Agreement) bear interest at the ABR plus the Applicable Rate.<br><br>The ABR is equal to the greater of: (i) the rate of interest publicly announced by JPMorgan Chase Bank, N.A. as its prime rate in effect at its principal office in New York, and (ii) the federal funds rate effective from time to time plus 0.5%.  The Adjusted LIBO Rate is equal to the rate at which Eurodollar deposits in the London interbank market for the applicable borrowing period are quoted on the Dow Jones Market Service, as adjusted to give effect to statutory reserve requirements for Eurocurrency liabilities established by the Board of Governors of Federal Reserve System of the United States.  The Applicable Rate varies between 0.575% and 1.25% for Eurodollar Borrowings (as defined in the Credit Agreement), and between 0% and 0.25% for ABR Borrowings (as defined in the Credit Agreement), based upon a ratio, determined as of the end of each of the Company&#x2019;s fiscal quarters ending on and after December 31. 2006 of (i) Consolidated Total Indebtedness (as defined in the Credit Agreement) minus the amount by which the sum of cash and Permitted Investments (as defined in the Credit Agreement) maintained by the Company as of the end of such fiscal quarter exceeds $30 million, if at all, to (ii) Consolidated EBITDA (as defined in the Credit Agreement) for the trailing four fiscal quarters.<br><br>The Credit Agreement contains customary representations, warranties, conditions precedent, events of default, indemnities and affirmative and negative covenants, including covenants that, among other things, require the Company to maintain certain leverage and interest coverage ratios, and restrict the ability of the Company to: incur indebtedness; incur liens; sell or otherwise dispose of assets, including capital stock of subsidiaries; enter into mergers or consolidations; enter into transactions with affiliates; and use proceeds of borrowings under the Credit Agreement for other than permitted uses.  These covenants are subject to a number of important exceptions and qualifications.  Certain changes in control of the Company would constitute an event of default under the Credit Agreement.<br><br>The proceeds from the credit facility will be used for general corporate purposes, which may include working capital requirements, strategic acquisitions and authorized share repurchases.<br><br>A copy of a press release announcing the signing of the Credit Agreement is attached hereto as Exhibit 99.1, and is incorporated herein by reference.<br>

  Item 1.01 Entry into a Material Definitive Agreement.
  On December 20, 2006, Arbitron Inc. (the "Company") entered into a $150 million senior unsecured credit facility with JPMorgan Chase Bank, National Association as Administrative Agent, Citizens Bank of Pennsylvania as Documentation Agent, Citibank, N.A. and Wachovia Bank, National Association as Co-Syndication Agents, J.P. Morgan Securities Inc. as Sole Bookrunner and Sole Lead Arranger, and a syndicate of lenders from time to time party thereto.  The Credit Agreement expires on December 20, 2011.
  The description of the Credit Agreement (the "Credit Agreement") set forth below is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which is attached as Exhibit 10.1 hereto and is incorporated by reference herein.  The Credit Agreement also provides access to up to an additional $50 million of financing through an expansion feature under which the aggregate commitment of the lenders may be increased up to $200 million, subject to the availability of additional commitments.  The credit facility includes a $15 million swing line commitment and a $15 million commitment for issuance of letters of credit.
  Borrowings under the credit facility bear interest at one of the two following rates, at the Company's option: (1) the Alternate Base Rate (the "ABR") plus the Applicable Rate, or (2) the Adjusted LIBO Rate plus the Applicable Rate; provided that all Swing Line Loans (as defined in the Credit Agreement) bear interest at the ABR plus the Applicable Rate.
  The ABR is equal to the greater of: (i) the rate of interest publicly announced by JPMorgan Chase Bank, N.A. as its prime rate in effect at its principal office in New York, and (ii) the federal funds rate effective from time to time plus 0.5%.  The Adjusted LIBO Rate is equal to the rate at which Eurodollar deposits in the London interbank market for the applicable borrowing period are quoted on the Dow Jones Market Service, as adjusted to give effect to statutory reserve requirements for Eurocurrency liabilities established by the Board of Governors of Federal Reserve System of the United States.  The Applicable Rate varies between 0.575% and 1.25% for Eurodollar Borrowings (as defined in the Credit Agreement), and between 0% and 0.25% for ABR Borrowings (as defined in the Credit Agreement), based upon a ratio, determined as of the end of each of the Company's fiscal quarters ending on and after December 31. 2006 of (i) Consolidated Total Indebtedness (as defined in the Credit Agreement) minus the amount by which the sum of cash and Permitted Investments (as defined in the Credit Agreement) maintained by the Company as of the end of such fiscal quarter exceeds $30 million, if at all, to (ii) Consolidated EBITDA (as defined in the Credit Agreement) for the trailing four fiscal quarters.
  The Credit Agreement contains customary representations, warranties, conditions precedent, events of default, indemnities and affirmative and negative covenants, including covenants that, among other things, require the Company to maintain certain leverage and interest coverage ratios, and restrict the ability of the Company to: incur indebtedness; incur liens; sell or otherwise dispose of assets, including capital stock of subsidiaries; enter into mergers or consolidations; enter into transactions with affiliates; and use proceeds of borrowings under the Credit Agreement for other than permitted uses.  These covenants are subject to a number of important exceptions and qualifications.  Certain changes in control of the Company would constitute an event of default under the Credit Agreement.
  The proceeds from the credit facility will be used for general corporate purposes, which may include working capital requirements, strategic acquisitions and authorized share repurchases.
