EXHIBIT 23.3 INDEPENDENT AUDITORS' REPORT The Board of Directors and Shareholders Zions Bancorporation: We have audited the accompanying consolidated balance sheet of Zions Bancorporation and subsidiaries as of December 31, 1999, and the related consolidated statements of income, cash flows, and changes in shareholders' equity and comprehensive income for each of the years in the two-year period ended December 31, 1999. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Zions Bancorporation and subsidiaries as of December 31, 1999, and the results of their operations and their cash flows for each of the years in the two-year period ended December 31, 1999, in conformity with accounting principles generally accepted in the United States of America. /s/KPMG LLP Salt Lake City, Utah February 7, 2000
