For the purposes of Equal Employment Opportunity (EEO) Component included in column "Racial/ethnic group representation of U.S. employees as reported on page 145 in the IPG ESG Report” for the percentage of 2020 racial/ethnic group representation of U.S. employees, the racial and ethnic diversity was identified by IPG Human Resources following an internal process aligned with the 2019 and 2020 EEO-1 Component 1 Data Collection Instruction Booklet, which allows use of employment records or observer identification to identify an employees’ race and ethnicity if an employee declines to self-report.
