Management's Discussion and Analysis of Financial Condition and Results of Operations, page 19 1. We note your response to comment 1. Please identify "Credit Agreement EBITDA" as a non-GAAP measure or explain why you do not believe the measure represents a non- GAAP measure. Refer to Item 10(e) of Regulation S-K. 2. We have reviewed your response to comment 2 but continue to believe that your presentation of operating expense ratios based on revenue before billable expenses is not appropriate. Please revise to eliminate the presentation of operating expenses as a percentage of revenues before billable expenses. Please note that we will not object to Philippe Krakowsky The Interpublic Group of Companies, Inc. September 19, 2022 Page 2 your presentation of segment EBITA and segment EBITA margin as a percentage of revenue before billable expenses since this is your segment measure of profitability as long as no totals or subtotals for your combined segment operations are provided. Form 8-K Filed February 10, 2022 Exhibit 99.1, page E-11 3. We note your response to comment 3 but do not believe your response addressed the concern raised in our comment. Removing the impact of your valuation allowance appears to be an individually tailored income tax recognition method. Please revise your presentation to remove this adjustment or tell us why you believe it is not an individually tailored recognition method. Refer to Question 100.04 of the staff's Compliance and Disclosure Interpretations on Non-GAAP Financial Measures.
