OMAHA, Neb. (AP) — Warren Buffett's company now owns more than 14 percent of the stock in kidney dialysis firm DaVita Inc.
Berkshire Hathaway Inc. said Thursday in a filing with the Securities and Exchange Commission that it owns 13.6 million shares of Denver-based DaVita.
When Berkshire first disclosed the DaVita investment at the end of last year, it held just 2.7 million shares. At the beginning of October, Berkshire held just 10 million shares.
Berkshire officials don't typically comment on these filings. The documents don't spell out whether Buffett himself or one of his company's two other investment managers made the DaVita investment.
Berkshire said it bought 635,633 DaVita shares last week at prices that range between $104.58 and $107.38.
DaVita runs nearly 2,000 outpatient dialysis clinics.
