Feb 13 (Reuters) - Berkshire Hathaway BRKa.N said on Thursday night it sold 203,091 shares of DaVita DVA.N, reducing its stake in the kidney dialysis services provider to about 35.89 million shares, a 45% stake worth nearly $6.4 billion.
In a regulatory filing, Berkshire said the February 11 sale was required pursuant to a share repurchase agreement, under which DaVita agreed on a quarterly basis to buy back enough shares to reduce Berkshire's ownership stake to 45%.
