UPDATE: 7/14 11:45AM

It has been brought to my attention that Berkshire does not own shares of Rohm & Haas. For some reason I incorrectly thought it did. Maybe Buffett used to own some of it, or maybe I just got confused some other way. At any rate, my apologies. Obviously, 2/3 of this post still applies, but just ignore the ROH part. Sorry for the confusion!

Things have not been great lately for Warren Buffett and Berkshire Hathaway (BRKA) shareholders. BRK stock has dropped more than 20% since December and large Buffett holdings in the financial services area such as American Express, Wells Fargo, Moody's, and U.S. Bancorp are hurting his equity portfolio. Buffett has also taken some heat for publicly bashing the use of derivatives, but privately writing billions in credit default swaps.

Despite the recent headwinds, you may have noticed that Buffett is still hitting some home runs. Just this year three Buffett investments have received takeover offers, all at significant premiums of 50% to 80%. What is amazing to me has been the prices offered for some of these companies. For instance, Mars is paying 32 times 2008 earnings for Wrigley (WWY). Dow Chemical (DOW) just offered a staggering 11.5 times EBITDA for chemical company Rohm and Haas (ROH).

Those are hefty prices by any measure, so I will be interested to see how smart those deals turn out to be several years from now. Buffett, for one, seems to think $80 per share is a bit steep for Wrigley. He is selling his stake to Mars for $80 per share, providing financing for the deal, and after the deal closes he inked a deal to buy a stake in the Wrigley subsidiary at a discount to the $80 purchase price. Not a bad deal if you can get it.

Full Disclosure: The author and/or his clients were long shares of Anheuser-Busch and U.S. Bancorp for investment purposes, and Wrigley as a merger arbitrage play, at the time of writing
