Warren Buffett, Delegator in Chief

Mr. Buffett “manages” Berkshire’s 257,000 employees with just 21 people at his headquarters in a small office in Omaha.

Mr. Buffett’s business partner, Charles Munger, once described Mr. Buffett’s day. He spends half of his time just sitting around and reading, Mr. Munger said. “And a big chunk of the rest of the time is spent talking one on one, either on the telephone or personally, with highly gifted people whom he trusts and who trust him.”

When questioned once about why Berkshire didn’t take a more active role in fixing Moody’s, the troubled credit rating agency, in which he was the largest shareholder, he declared: “I’ve never been to Moody’s. I don’t even know where they’re located.”

“If I thought they needed me I wouldn’t have bought the stock,” he added.

He sees himself less of an activist than as a passive investor, a stock picker with a nose for a good deal. “We don’t tell Burlington Northern what safety procedures to put in or AmEx who they should lend to,” he said at his annual meeting two years ago. “When we own stock, we are not there to try and change people.”
