Whats this about no more paper Class B stock certificates?
Most shareholders already hold their Class B shares in “book entry” form — an electronic record — with their stockbrokers or by Wells Fargo Shareowner Services, which is the agent for Berkshire in the railroad purchase. Each book entry Class B share would become 50 shares automatically when the split takes effect. Shareholders whose stock is all in book entry form don’t need to do anything. Shareholders can keep paper stock certificates, but it makes sense to send them to their brokers or to the Wells Fargo office to become book entries. Wells Fargo will send letters to shareholders who don’t submit their shares, urging them to send in the certificates. Shareholders should NOT destroy their old Class B certificates or try to return them to Berkshire. Book entry shares are less likely to be lost or stolen, and it’s cheaper for Berkshire to manage them. Shares owned by someone who can’t be reached could be signed over to the unclaimed property authority in the state where the person live
