DETROIT (Reuters) - The U.S. and Canadian governments exited their investments in Chrysler Group LLC on Thursday, making Fiat SpA the majority stakeholder in the U.S. automaker.

The Italian automaker has the right to appoint a majority of the company's board of directors, Chrysler said in a regulatory filing on Thursday.

Fiat owns 55.3 percent of Chrysler, or 53.5 percent on a fully diluted basis, the company said in the filing.

The remaining shares in Chrysler are held by the health care trust affiliated with the United Auto Workers, known as the VEBA. Chrysler and the UAW are expected to begin talks to negotiate a new four-year contract Monday.

The United States and Canada took equity stakes in Chrysler during the U.S. automaker's bankruptcy restructuring in 2009. Fiat said in early June that it would buy the U.S. and Canadian stakes in Chrysler.
