Publicis to Produce Citi's Brand Identity and Consumer Campaigns

April 30, 2007

Paris & New York – Citi and Publicis Groupe today announced Publicis has been selected to manage Citi's global corporate brand identity and Global Consumer Group (GCG) advertising campaigns. In order to provide Citi with superior expertise across a spectrum of disciplines, Publicis will draw upon resources from a variety of its global operations and agencies.

"As we considered how best to support our marketing initiatives, beginning with our corporate brand identity campaign, we looked for a company with extraordinary domestic and international capabilities," said Lisa Caputo, Chief Marketing and Community Relations Officer, GCG. "We have been impressed by Publicis' ability to customize and execute advertising programs across diverse geographies and cultures. Over the past seven years we have enjoyed many successes working with Fallon, a Publicis Groupe company, on our consumer advertising campaigns, and Fallon will continue to provide support in select international markets. Publicis will help propel our Citi brand identity messaging and deliver strategic advertising support for our outstanding array of financial products and services."

Citi will introduce a new corporate brand identity advertising campaign, developed by this Publicis team, in May of this year. Eventually the themes from that campaign will be integrated into Citi's advertising and marketing programs for its Global Consumer Group's products and services.
