Liberty Mutual Launches National Advertising Campaign Posing the Question: ''Responsibility. What's Your Policy?''; New Fully Integrated Campaign Developed by Hill Holliday Includes National Television, Print and Online Advertising.

BOSTON -- Liberty Mutual - the sixth largest property and casualty insurer in the U.S. - tonight launches a major national advertising campaign and tagline, "Responsibility. What's Your Policy?," with a 60-second branding spot during the season finale of NBC's, "Deal or No Deal," which airs at 8:00 p.m. EDT.

The total media spend for this national advertising campaign is in excess of $38 million.

Liberty Mutual will air the branding spot on cable and all major networks. It will add four 30-second national television spots focusing on home and automobile insurance in mid-June. Complementing the national television debut will be four national print ads focused on personal insurance and two print ads focused on commercial insurance. The print ads will run in a variety of national publications such as the New York Times, USA TODAY, Time, Money, U.S. News & World Report, Sports Illustrated, The Wall Street Journal, Forbes, Fortune, The Economist, Business Insurance and CFO.

The new campaign expresses the responsibility theme through actions of ordinary people doing small, but responsible things to make every day life a little bit better.

"Responsibility is a core value for people and is at the heart of our mission to help people live safer, more secure lives," said Steve Sullivan, Liberty Mutual Group senior vice president, communications. "Our new advertising reinforces this core value while asking consumers the thought-provoking question, 'Does your insurer share your philosophy?'"

Mike Sheehan, president and CEO of Hill Holliday said, "Liberty Mutual is a rock-solid brand with a powerful story to tell. As we developed the campaign, the theme of 'responsibility' quickly rose to the top. It's an authentic, differentiating rallying cry for Liberty Mutual and its customers. Beyond being strictly about Liberty Mutual, this campaign is about recognizing, celebrating and 'living' responsibility."

The online campaign leverages the interpersonal nature of the Internet to establish a dialogue between Liberty Mutual and the public around the central question posed by the tagline: "Responsibility. What's Your Policy?" Banner ads will feature provocative questions related to the insurance category and will be built around the theme of responsibility. These ads drive people to a real-time survey where they can cast their vote, provide a written response and submit topics for future consideration. Launching tomorrow, visitors can access the new Web site, www.whatsyourpolicy.com, through www.msnbc.com, www.nytimes.com, www.espn.com, www.si.com and www.weather.com.
