Dividend Reinvestment and Stock Purchase Plan

This plan requires that you purchase at least one share of stock. You can then make optional cash payments, from $50 to $10,000 per month, through the plan to increase your investment. Also, once you are a shareholder of record, you may ask Computershare, our transfer agent, to code your account for dividend reinvestment.
