Berkshire Hathaway, class B, will be added to the S&P 500 and S&P 100 stock indexes after the market closes on Feb. 12, replacing Burlington Northern Santa Fe, according to an S&P statement released after the U.S. stock market closed Tuesday.
Berkshire Hathaway is acquiring Burlington Northern Santa Fe, pending final approvals. The deal is expected to close Feb. 12.
S&P will add Berkshire Hathaway, which is controlled by Warren E. Buffett, CEO, at a date to be announced, the statement said.
“The price in the index will be based on the B shares, because there is no question that is the more liquid class,” David M. Blitzer, S&P managing director and chairman of the index committee, said in an interview.
