Last year, Warren received a letter from Steve Levy, Bell Laboratories’ CEO, asking that we look at the family-owned business he manages for the daughters of founder Malcolm Stack. Steve’s letter was perfect. Bell Laboratories meets a persistent need: rodent control. In Steve’s words, it possesses “high operating margins, very good historical growth and future growth potential, easy to understand and always needed, and a strong management team.” In our words: a business with durable advantages and long-term economic prospects run by excellent managers. We only wish it had been ten times bigger.
