What happens to Berkshire Hathaway (NYSE:BRK-A) (NYSE:BRK-B) once Warren Buffett is no longer around? While many assume Berkshire won't survive in its current form, George Washington University law professor Lawrence Cunningham says it will not only survive, but thrive.

What makes him think that?

In his upcoming book, Berkshire Beyond Buffett: The Enduring Value of Values, Cunningham talks about the "glue" that holds together the $300 billion conglomerate. The dozens of companies in the Berkshire empire are held together by nine values, the most important of which are a sense of permanence, and autonomy.

Motley Fool analyst Rex Moore was at the Berkshire Hathaway annual meeting in Omaha and was able to chat with Cunningham. In the video below, Cunningham explains more about these values, and the one thing that could undermine them.
