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, a new book makes a compelling case that it will not only survive, but thrive.

Lawrence Cunningham is a law professor at George Washington University, and one of the world's leading Berkshire Hathaway experts. When he hears "Warren is so special that Berkshire can't survive losing him," he counters with "Berkshire is so special that it can survive losing Warren."

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 his upcoming book, Berkshire Beyond Buffett: The Enduring Value of Values, and why the $300 billion conglomerate will hold together in the post-Buffett years.
