Household, acquired last year by the world's second largest bank -- HSBC Holdings -- did not have an agency of record in the past, working with a variety of agencies in its various business units instead.
Mark Friedlander, Household's director of PR, said: "our goal was to have one agency provide us with support for the entire US operation."
Household spoke with nine major national agencies in December and narrowed the field to three finalists in January before selecting Ketchum.
"We really liked the way they approached issues we put on the table," Friedlander said of Ketchum.
Mike Hatcliffe, head of the corporate practice for Ketchum Midwest will oversee the account. It is still being determined how many staffers Ketchum will put on the Household business. The account will be handled mainly out of Chicago with support from Ketchum's New York and Washington, DC offices.
Ketchum will work on external communications, PR for Household business lines, corporate social responsibility outreach and supporting the company's efforts to promote itself as a good place to work.
