This is the first common stock dividend by Edison International since Oct. 2000. “Resumption of common stock dividends has been a primary goal for us. We were forced by the effects of the power crisis three years ago to break a record of 90 years of uninterrupted dividend payments. Our shareholders make our business possible, and we are delighted to be able now to provide this return on their investment. This also will help us to access capital to meet customer needs,” said John E. Bryson, Chairman, Edison International.
