Investors have worried about what will happen to Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B) once Warren Buffett passes on. 

While he certainly isn't getting any younger, Buffett has built an extremely successful company that should continue to sail long after he's left the helm. He's expressed a deep level of confidence in his successor, and has also indicated to the market that shares of Berkshire are crazy cheap today. Even after sharing this tidbit with investors, shares are trading only at a 9% premium to the effective price floor he's established. 

While massive conglomerates like this can be difficult to price, with Berkshire Hathaway investors still can sleep soundly knowing they're getting a great investment.
