Amendment Description	Radio One, Inc. (“Radio One” or the “Company”) is filing this Amendment No. 1 ("Amendment") on Form 10-Q/A to its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2013 to correct and restate classification errors related to the condensed consolidating financial statements of guarantors/non-guarantors in the footnote to its previously filed financial statements in its quarterly report on Form 10-Q for the quarter ended March 31, 2013 for the reason described below. The restatement is solely the result of classification errors of certain items in Note 12 included in those financial statements. The classification errors, which have no impact on the Company’s consolidated balance sheets, consolidated statements of operations, consolidated statements of comprehensive income, consolidated statements of changes in equity or consolidated statements of cash flows for this previously reported period, relate to: (i) including TV One, LLC (“TV One”) in the “Radio One, Inc.” column in the condensed consolidating financial statements in the March 31, 2013 Form 10-Q although TV One is a non-guarantor subsidiary of the Company under its outstanding notes registered under the Securities Act of 1933; (ii) including Reach Media, Inc. (“Reach Media”) in the “Radio One, Inc.” column in the condensed consolidating financial statements in the March 31, 2013 Form 10-Q although Reach Media was a guarantor subsidiary for that reporting period; (iii) the presentation and classification of certain intercompany transactions in the condensed consolidating statement of cash flows; and (iv) the presentation of certain consolidation adjustments within the condensed consolidating financial information. Additionally, the Company determined separate financial statements for Reach Media should have been included in the Form 10-Q for the quarter ended March 31, 2013 because it is not wholly owned by the Company. The Company also identified an immaterial classification error related to the cash flow statement presentation in its previously filed interim consolidated financial statements as of and for the three month period ended March 31, 2013. The Company improperly classified proceeds from the sale of its Columbus station (WJKR-FM) as cash flows from discontinued operations within operating activities rather than as a source of cash flows from investing activities. In connection with the filing of its Form 10-Q/A as of and for the three month period ended March 31, 2013, the Company has corrected this classification error. The impact on the financial statements was to overstate cash flows from operating activities by approximately $4.0 million and understate cash flows from investing activities by approximately $4.0 million for the three month period ended March 31, 2013. The classification error had no effect on operating cash flows from continuing operations. Further, the classification error had no effect on the Company’s consolidated balance sheet, consolidated statement of operations, consolidated statement of comprehensive loss or consolidated statement of changes in equity as of and for the three month period ended March 31, 2013. This Amended 10-Q does not reflect events occurring after the filing of the original Form 10-Q and does not modify or update the disclosure in the original 10-Q, other than for (i) the changes noted above, (ii) the evaluation and current developments of controls and procedures in Item 4; and (iii) the filing of certifications of our principal executive officer and principal financial officer pursuant to Rule 13a-14 of the Securities Exchange Act of 1934 and Section 906 of the Sarbanes-Oxley Act of 2002. Except as described above, this Form 10-Q/A does not amend, update or change the financial statements or any other items or disclosures made to the Form 10-Q for the quarter ended March 31, 2013.
