TD Ameritrade is reviewing its creative business at Ogilvy & Mather.
Ogilvy's assignment includes traditional and online ads as well as direct marketing. The online brokerage's annual media spending was not immediately available.
Ogilvy, whose roots with the company date back to Ameritrade in 1997, plans to defend. The agency, which handles the account out of its New York office, declined to comment.
A TD Ameritrade representative confirmed the review, but declined to discuss the process, including the company's timetable for completing it. The company is based in Omaha, Neb.
