Non-GAAP Financial Measures

This news release contains non-GAAP financial measures as defined by the Securities and Exchange Commission Regulation G; pursuant to the requirements of this regulation, reconciliations of these non-GAAP measures to their comparable GAAP measures are included in the attached financial tables. To assess the underlying operational performance of the continuing operations of the business for the quarter and to have a basis to compare underlying operating results to prior and future periods, management uses operating income, net income from continuing operations and diluted earnings per share from continuing operations metrics excluding certain unusual, non-operational or restructuring-related activities.

These items are relevant in evaluating the overall performance of the business. Limitations associated with the use of these non-GAAP measures include that these measures do not include all of the amounts associated with our results as determined in accordance with GAAP. Management compensates for these limitations by using the non-GAAP measures, operating income, income from continuing operations, net of tax and diluted earnings per share from continuing operations excluding the items above, and the GAAP measures, operating income, income from continuing operations, net of tax and diluted earnings per share, in its evaluation of performance. There is no material purpose for which we use these non-GAAP measures beyond those described above.

The Company presents the non-GAAP financial measures EBITDA and adjusted EBITDA because management uses these measures to monitor and evaluate the performance of the business and believes the presentation of these measures will enhance the investors’ ability to analyze trends in the business and evaluate the Company’s underlying performance relative to other companies in the industry.

Management uses the non-GAAP metrics free cash flow and adjusted free cash flow to assess the financial performance of the Company. Convergys’ management believes that free cash flow and adjusted free cash flow are useful to investors because they relate the operating cash flow of the Company to the capital that is spent to continue and improve business operations, such as investment in the Company’s existing businesses. Further, free cash flow and adjusted free cash flow facilitate management’s ability to strengthen the Company’s balance sheet, to repurchase the Company’s stock, to pay dividends, and to repay the Company’s debt obligations. Management also

believes the presentation of these measures will enhance the investors’ ability to analyze trends in the business and evaluate the Company’s underlying performance relative to other companies in the industry. Limitations associated with the use of free cash flow and adjusted free cash flow include that they do not represent the residual cash flow available for discretionary expenditures as they do not incorporate certain cash payments including payments made on capital lease obligations or cash payments for business acquisitions. Management compensates for these limitations by utilizing the non-GAAP measures, free cash flow and adjusted free cash flow, and the GAAP measure, cash flow from operating activities, in its evaluation of performance. There are no material purposes for which we use these non-GAAP measures beyond the purposes described above.

These non-GAAP measures should be considered supplemental in nature and should not be considered in isolation or be construed as being more important than comparable GAAP measures. The non-GAAP financial information that we provide may be different from that provided by our competitors or other companies.

These charges and credits are relevant in evaluating the overall performance of the business.

Limitations associated with the use of these non-GAAP measures include that these measures do not include all of the amounts associated with our results as determined in accordance with GAAP.

(Unaudited)

Management uses free cash flow and adjusted free cash flow to assess the financial performance of the Company.
