OMAHA, Neb. (AP) - Billionaire Warren Buffett's company is revealing new investments in Deere & Co. and Wabco Holdings in a busy quarter of buying and selling for Berkshire Hathaway Inc.

The Omaha-based company filed a quarterly update on its U.S. stock holdings Wednesday.

Berkshire added to its existing investments in Wells Fargo, Bank of New York Mellon Corp., General Motors and DaVita Inc.

Berkshire also reduced its stakes in Johnson & Johnson, Kraft Foods, Lee Enterprises , Procter & Gamble and US Bancorp.

The report doesn't distinguish between Buffett's stock picks and those made by the company's other investment managers, Todd Combs and Ted Weschler. Combs started at Berkshire last year, and Weschler joined the company early this year.

Combs and Weschler manage roughly $4 billion.
