Buffett: I Was Wrong on Anheuser-Busch

Buffett doesn't believe in hostile takeovers. Capable, cooperative existing management is worth a large premium, as far as he is concerned. When faced with a hostile suitor, otherwise well-run companies often take rash, unexpected actions. We've seen this before. If, in an attempt to thwart InBev, BUD leveraged itself to buy, say, Sapporo Breweries, the result for shareholders could have been disastrous. Ego is a large liability, and when management uses it in lieu of rational business logic, the right place for investors to be is nowhere near.

At $63 a share, Buffett got most of the takeover premium, without taking any of the proxy battle risk. Being humble, he calls it a mistake, but faced with the same situation again, he would do exactly the same, and rightly so.

Warren Buffett Accumulates NRG Energy, Ingersoll-Rand and Union Pacific

Rong,

The price of Berkshire stock carries a substantial premium over the price of the stock portfolio it holds. This premium may or may not be justified; Buffett himself prefers buying shares of IR and NRG to buying back shares of BRK, and for a good reason too: he doesn't consider the price of BRK shares to be a bargain, unlike that of IR and NRG.

Berkshire is not a mutual fund or an ETF. If the primary insurance and reinsurance businesses of Berkshire falter, an investor may do much better by holding KO, PG, WFC, AXP and the other stocks in the portfolio than by owning shares of BRK.
