(b) Exhibits - Consent of Independent Certified Public Accountants Independent Auditors' Report The Trust Committee Zions Bancorporation Employee Investment Savings Plan: We have audited the accompanying statements of net assets available for benefits of Zions Bancorporation Employee Investment Savings Plan as of December 31, 1999 and 1998, and the related statements of changes in net assets available for benefits for each of the years in the three-year period ended December 31, 1999. These financial statements are the responsibility of the plan administrator. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit 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 the plan administrator, 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 financial statements referred to above present fairly, in all material respects, the net assets available for benefits of Zions Bancorporation Employee Investment Savings Plan as of December 31, 1999 and 1998, and the changes in net assets available for benefits for each of the years in the three-year period ended December 31, 1999, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes as of December 31, 1999, is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic 1999 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. (a) General The Plan is a single employer contributory plan that is designed to provide retirement benefits for eligible employees under a pretax salary reduction (deferral) arrangement and, if employees so elect, an opportunity to acquire stock ownership in Zions Bancorporation (the Company). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, (ERISA). Effective July 22, 1999, the Company terminated the Zions Bancorporation Profit Sharing Plan (the Profit Sharing Plan). Upon termination of the Profit Sharing Plan, all of the Profit Sharing Participants' outstanding balances were transferred to, and merged with, the Plan. This transfer totaled $21,288,158 and is reflected on the accompanying statements of changes in net assets available for benefits as transfers from affiliated plan. Transfers from non-affiliated plans are the result of bank mergers effected by the Company. (b) Eligibility Participation in the Plan is voluntary. An employee is eligible to become a participant on January 1, April 1, July 1, or October 1, whichever coincides with, or immediately follows, the latter of the date on which the employee completes at least 1,000 hours of service during 12 continuous months and attains the age of 21. At December 31, 1999 and 1998, there were 5,476 and 3,893 participants, respectively, in the Plan. (c) Employee and Company Contributions Participants may elect to contribute one to fifteen percent of their compensation to the Employee Investment Savings Plan, limited by participant contributions made to the Zions Bancorporation Employee Stock Savings Plan. The Company contributes an amount equal to 25 percent of the contribution made by each participant up to five percent of their compensation with no match made on contributions in excess thereof. The maximum amount a participant may contribute to the Plan in a calendar year is the lesser of fifteen percent of their compensation, or $10,000 for 1999 and 1998. (d) Allocation of Income or Loss Investment income or loss is allocated to each participant's account in proportion to the investment shares held in that participant's account to the total investment shares held in the Plan. 4 (continued) ZIONS BANCORPORATION EMPLOYEE INVESTMENT SAVINGS PLAN Notes to Financial Statements December 31, 1999 and 1998 (e) Vesting and Payment of Benefits Employee contributions and the employees' share of the Company contributions are 100 percent vested at all times. Benefits are paid upon death, disability, retirement, or earlier, subject to certain restrictions. Benefits are paid in shares of stock and/or cash pursuant to the nature of the investment vehicle selected by the participant. (f) Investment Options As of December 31, 1999, the Plan maintains three separate types of investment funds: (i) Company securities, which consist of Company stock; (ii) Accessor funds, consisting of seven investment options (Accessor growth fund adv class, Accessor value and income adv class, Accessor small to mid-cap adv class, Accessor international equity adv class, Accessor intermediate fixed income adv class, Accessor mortgage securities adv class, and Accessor short-term intermediate fixed income adv class); and (iii) Fidelity U.S. government reserves. (g) Participant Loans Beginning October 1, 1992, a participant who is an active employee may apply for and obtain a loan of up to the lessor of $50,000 or 50 percent of the eligible amounts in their account. Loans are secured by the participant's account. Loan repayment is made through payroll deduction. (h) Plan Amendments In 1998, the Benefits and Pension Committee approved amendments to the terms of the Plan. The following significant amendments became effective January 1, 1999. Enrollment date frequency has been changed from semi-annually to quarterly. Employees must be 21 and must have completed 1 year of eligibility service in order to participate in the Plan. However, the definition of one year of eligibility service has been expanded to include employees for whom one year has past since (a) commencement date with a previous employer that sponsored a similar 401(k) plan in which the employee participated and (b) commencement date with a Merged Employer. The amount by which a participant's annual compensation is reduced under the Salary Reduction Agreement may be changed by a participant no more than once in any quarter. A participant may elect to transfer assets between funds up to three times in any calendar quarter, each at least five business days apart. Funds available for withdrawal have been amended to include funds available from rollover contributions. If a participant has made a rollover contribution in the Plan, and if the participant's accrued benefit at the time of such a withdrawal request is or has been greater than $5,000, no withdrawal may be made prior to normal retirement age unless the participant first consents in writing. Hardship withdrawals from a participant's rollover account will have no effect upon any benefits provided under the Plan. The limit for lump-sum payments to disabled participants is $5,000. (i) Plan Termination Although the Company has not expressed any intent to do so, it has the right under the Plan to discontinue contributions at any time and to terminate the Plan subject to provisions of ERISA. 5 (continued) ZIONS BANCORPORATION EMPLOYEE INVESTMENT SAVINGS PLAN Notes to Financial Statements December 31, 1999 and 1998 (2) Summary of Significant Accounting Policies The following is a summary of significant accounting policies followed by the Plan in the preparation of its financial statements: (a) Basis of Presentation The Plan's financial statements are presented on the accrual basis of accounting. (b) Investments Quoted market prices have been used to determine the fair value of investments. Purchases and sales of investments are recorded on a settlement-date basis, which does not materially differ from using the trade-date basis required by generally accepted accounting principles. Participant loans are valued at cost which approximates fair value. Net unrealized appreciation represents the difference between the book value and the market value of investments held at year-end. Book value is the market value at the end of the previous fiscal year, or cost if the investment was purchased during the year. (c) Cost of Administration All costs of administration are currently being paid by the Company, however the costs of administration may be paid by the Plan. (d) Cash and Cash Equivalents Cash and cash equivalents include cash and short-term investments with maturity dates of 90 days or less. (e) Reclassifications Certain reclassifications have been made in the 1998 and 1997 financial statements to conform with the 1999 presentation. (f) Use of Estimates The preparation of the financial statements and supplemental schedule in conformity with generally accepted accounting principles requires the plan administrator to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and supplemental schedule and the reported amounts of changes in net assets during the reporting period. Actual results could differ from those estimates. 6 (continued) ZIONS BANCORPORATION EMPLOYEE INVESTMENT SAVINGS PLAN Notes to Financial Statements December 31, 1999 and 1998 (g) Concentration of Investments Included in the Plan's net assets available for benefits at December 31, 1999 and 1998 are investments in common stock of the Company amounting to $112,880,506 and $111,008,195, respectively, whose value could be subject to change based on market conditions. These investments represented 2.23 percent and 2.13 percent ownership of the Company's outstanding common stock at December 31, 1999 and 1998, respectively. (3) Tax Status The Plan obtained its latest determination letter on June 5, 1996, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable provisions of the Internal Revenue Code (IRC) and therefore are exempt from Federal income taxes. The Plan has been amended since receiving the determination letter and has submitted to the Internal Revenue Service for a determination letter. In the opinion of the plan administrator and the Plan's tax counsel the Plan is designed and is currently being operated in compliance with the applicable provisions of the IRC. (4) Zions Bancorporation Common Stock At December 31, 1999 and 1998, the investment in common stock of the Company consisted of 1,907,168 and 1,779,691 shares, respectively. (5) Investments In September 1999, the American Institute of Certified Public Accountants issued Statement of Position 99-3, Accounting for and Reporting of Certain Defined Contribution Plan Investments and Other Disclosure Matters (SOP 99-3). SOP 99-3 simplifies the disclosure for certain investments and is effective for plan years ending after December 15, 1999, with earlier application encouraged. The Plan adopted SOP 99-3 during the Plan year ended December 31, 1999. Accordingly, information previously required to be disclosed about participant-directed fund investment programs are not presented in the Plan's 1999 financial statements. The following investments represent five percent or more of the net assets available for plan benefits at December 31: 1999 1998 ------------ ------------ Zions Bancorporation common stock ... $112,880,506 133,545,842 Accessor growth fund adv class ...... 15,777,590 8,495,197 Accessor small-to-mid cap ........... 9,124,792 n/a 7 (continued) ZIONS BANCORPORATION EMPLOYEE INVESTMENT SAVINGS PLAN Notes to Financial Statements December 31, 1999 and 1998 Net appreciation (depreciation) on the Plan's assets during the year ended December 31, 1999 was as follows: 1999 ----------- Zions Bancorporation common stock ... $(4,618,395) Accessor mutual funds ............... 6,417,766 ----------- $ 1,799,371 =========== 8 SCHEDULE I ---------- ZIONS BANCORPORATION EMPLOYEE INVESTMENT SAVINGS PLAN Line 27a - Schedule of Assets Held for Investment Purposes December 31, 1999 (a) (d) Party in (b) (c) Current interest Issuer Investment description value - -------- --------------------- ------------------------------------------------ -------------- Investments at fair value determined by quoted market prices: * Zions Bancorporation Zions Bancorporation common stock (1,901,168 shares) $112,880,506 Accessor Accessor International Equity (ACIEX) Accessor mutual fund (260,737 units) 5,611,064 Accessor Accessor Growth (AGROX) Accessor mutual fund (449,662 units) 15,777,590 Accessor Accessor Intermediate Fixed Income (AIFIX) Accessor mutual fund (339,927 units) 3,841,178 Accessor Accessor Mortgage (AMSFX) Accessor mutual fund (117,070 units) 1,402,496 Accessor Accessor Short Fixed Income (ASIFX) Accessor mutual fund (74,250 units) 878,377 Accessor Accessor Small/ Mid (ASMCX) Accessor mutual fund (333,161 units) 9,124,792 Accessor Accessor Value/ Income (AVAIX) Accessor mutual fund (301,603 units) 6,242,762 Accessor Accessor U.S. Government Money Accessor mutual fund (5,642,572 units) 5,621,305 * Zions Bancorporation Participant loans (interest rates ranging from 7% to 10%) 1,599,442 * Zions Bancorporation Money market accounts 100,153 ----------- $163,079,665 =========== Notes: * Party-in-interest There were no nonexempt party-in-interest transactions.
