Harvester shareholders approved a name change.

The 155-year-old company will now be known as Navistar International. The name change, which won 97% approval, will cost the company about $10 million, according to Donald Lennox, chairman and chief executive. Navistar will begin trading on the New York Stock Exchange today under the exchange symbol NAV and will be abbreviated in the stock tables starting Saturday as Navistr. The company had five years to drop the International Harvester name and the IH logo after selling its unprofitable farm equipment business last year to Houston-based Tenneco.
