¨ Written communications pursuant to Rule 425 under the Securities Act (17 CFR 230.425)

In Exhibit 99.1 to this report, Convergys Corporation (“Convergys” or the “Company”) reflects for all periods presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009 (the “2009 Form 10-K”), the following reclassifications and changes that occurred in the quarter ended March 31, 2010:

As required by applicable accounting standards, the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2010 (the “March 31, 2010 Form 10-Q”) and consolidated financial statements issued by the Company reflect this reclassification and change to the Company’s reportable segments, including reclassification of all comparative prior period information.

On March 4, 2010, Convergys, Convergys Customer Management Group, Inc., Convergys Learning Solutions, Inc. and Convergys CMG Utah, Inc. signed a definitive Master Purchase Agreement to sell the Company’s HR Management business segment (the “Business”) to NorthgateArinso (“NGA”). Effective June 1, 2010, the Sellers substantially completed the sale of the Business. While the Company is a party to a transition services agreement, the Company has determined that it has no significant continuing involvement in the operations of HR Management. Accordingly, the net assets of HR Management are presented separately as held for sale and discontinued operations and the operating results are presented within discontinued operations for all periods presented in Exhibit 99.1 to this report.

For 2007 through 2009, we had three reportable segments, (i) Customer Management, which provides agent-assisted services, self-service, and intelligent technology care solutions; (ii) Information Management, which provides business support system (BSS) solutions; and (iii) HR Management, which provides human resource business process outsourcing solutions. In connection with the sale of the HR Management line of business, the Company reorganized its reportable segments into two segments; Customer Management and Information Management.

Items 6, 7, 7A and 8 of Part II and Item 15 of Part IV of the 2009 Form 10-K, updated to reflect the reclassifications and changes described above, are being filed as Exhibit 99.1 to this report and are hereby incorporated by reference herein. No items of the 2009 Form 10-K other than those identified above are being revised by this filing. Information in the 2009 Form 10-K is generally stated as of December 31, 2009, and this filing does not reflect any subsequent information or events other than the reclassification and other changes described above and the subsequent events disclosure in Note 20 of “Notes to Consolidated Financial Statements” included under Item 8. Without limitation of the foregoing, this filing does not purport to update the Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in the 2009 Form 10-K for any forward-looking statements, other than the events described above. More current information is contained in the March 31, 2010 Form 10-Q and the Company’s other filings with the U.S. Securities and Exchange Commission for periods and events occurring after December 31, 2009. This report should be read in conjunction with the 2009 Form 10-K, and the March 31, 2010 Form 10-Q and other filings.
