Also today the Board of Directors approved a regular quarterly dividend of $0.23 per share on the company’s common stock and also authorized a special cash dividend of $1.50 per share. “Given the potential significant increases in tax rates on dividends beginning next year, and our strong levels of capital, it is an opportune time to provide this special dividend distribution to our shareholders before the end of the year,” David W. Kemper, chairman and CEO, said. "After this special dividend, our capital ratios will continue to be very strong, and together with our ongoing earnings power, we will have ample capital to support organic balance sheet growth and continue our stock buyback program and regular dividend practices, along with expansion through acquisition should opportunities arise.” Both dividend payments will be payable December 17 to stockholders of record at the close of business on November 30, 2012. The dividend will not be payable on any shares to be issued pursuant to the 5% stock dividend also declared on this date. About Commerce Bancshares, Inc. Commerce Bancshares Inc.
