What is the difference between holding shares as a stockholder of record and a beneficial owner?
If your shares are registered directly in your name with the transfer agent, Wells Fargo Bank Minnesota, N.A., you are considered, with respect to those shares, the “stockholder of record.” If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of shares held in street name.
