Our report states, "We previously audited and reported on the consolidated statements of income, stockholders' equity, and cash flows of Keokuk Bancshares, Inc. for the year ended September 30, 1993, prior to their restatement for the 1994 pooling of interests. The contribution of Keokuk Bancshares, Inc. and subsidiaries to net interest income and net income represented 15 and 17 percent for 1993 of the respective restated totals.
