NEW YORK (Reuters) - Berkshire Hathaway Inc's (BRK-A) BNSF Railway Co has moved Chief Executive Matthew Rose to an executive chairman role, renewing speculation he might be in line to replace Warren Buffett at Berkshire's helm.
As executive chairman, Rose, 54, will work on organizational planning, market positioning and public policy at BNSF over the next decade, the company said on Wednesday.
Carl Ice, 57, will replace Rose as chief executive at the nation's largest railroad, starting on January 1.
Ice has been at the railroad for 34 years, and been its president since November 2010.
"Buffett has a track record of retaining good executives for long periods of times, and this will potentially free up Matt Rose to assist with other projects with Berkshire as warranted," said James Armstrong, president of Henry H. Armstrong Associates in Pittsburgh, which invests more than $400 million, roughly 25 percent of which is in Berkshire.
"Rose is likely on the short list to become CEO," Armstrong added.
Berkshire bought the roughly 77 percent of the former Burlington Northern Santa Fe Co it did not already own for $26.5 billion in 2010.
In this year's third quarter, the railroad posted a $989 million profit, about 20 percent of Berkshire's $5.05 billion.
"BNSF's performance has far exceeded the high expectations I had at the time of Berkshire's purchase," Buffett said in a statement. "The combination of Matt's and Carl's talents is the perfect arrangement for the future. I consider Berkshire very fortunate to have these men at BNSF's helm."
Rose was not immediately available for an interview. Buffett, through an assistant, did not immediately respond to a request for further comment.
"YOUNG AND TALENTED"
Considered one of the world's greatest investors, Buffett is now 83 and Berkshire has been preparing for many years for his eventual departure from the company he has run since 1965.
Speculation about who could succeed the second-richest American have picked up in recent years as Buffett has aged and survived prostate cancer.
Berkshire plans to split Buffett's role in three, with one person serving as chief executive, Buffett's son Howard as non-executive chairman, and one or more others as chief investment officer.
The Omaha, Nebraska-based company has more than 80 units selling such things as Russell athletic apparel, Geico car insurance, chemicals and furniture. It also owns dozens of newspapers, including the Omaha World-Herald.
Buffett has said that he and Berkshire's board are in agreement on who would step in as chief executive when the need arises, but has not yet publicly identified that person. He has said Berkshire has three internal candidates, all men.
Investors have speculated that other candidates could be insurance chief Ajit Jain, MidAmerican Energy chief Greg Abel, or perhaps portfolio manager Ted Weschler. Some have also mentioned Geico's Tony Nicely, but he is older than the others.
"Rose is young and talented, and when you're young and talented, you're not looking for ways to do less," said Thomas Russo, a partner at Gardner Russo & Gardner in Lancaster, Pennsylvania. "He may have to do less on a daily basis at Burlington, which would free up his time to work on other things at Berkshire."
Russo helps invest more than $6 billion, of which more than 10 percent is in Berkshire.
The Burlington transition is similar to what occurred at MidAmerican Energy in 2008, when David Sokol became chairman, and Abel replaced him as chief executive.
Sokol was also considered a candidate to succeed Buffett as Berkshire chief executive. He left the company abruptly in 2011 amid questions about a personal investment in a chemicals company he was negotiating for Berkshire to buy.
In Wednesday trading, Berkshire Class A shares fell $1,840 to $171,630 and its Class B shares fell $1.10 to $114.51.
