EXHIBIT 99.1 UNITED SECURITY BANCORPORATION PROFIT SHARING 401(k) PLAN INDEPENDENT AUDITOR'S REPORT and FINANCIAL STATEMENTS DECEMBER 31, 2000, 1999 AND 1998 CONTENTS -------------------------------------------------------------------------------- PAGE INDEPENDENT AUDITOR'S REPORT 1 FINANCIAL STATEMENTS Statements of net assets available for benefits 2 Statement of changes in net assets available for benefits 3 Notes to financial statements 4-6 SUPPLEMENTAL SCHEDULE Schedule of assets held for investment purposes at end of year 7 INDEPENDENT AUDITOR'S REPORT To the Board of Trustees United Security Bancorporation Profit Sharing 401(k) Plan We have audited the accompanying statements of net assets available for benefits of the United Security Bancorporation Profit Sharing 401(k) Plan as of December 31, 2000 and 1999, and the related statement of changes in net assets available for benefits for each of the three years in the period ended December 31, 2000. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these 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 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 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 financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2000 and 1999, and the changes in net assets available for benefits for each of the three years in the period ended December 31, 2000, in conformity with accounting principles generally accepted in the United States of America. Our audits were performed 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 is presented for purposes 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 is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ Moss Adams LLP Everett, Washington July 26, 2001 1 UNITED SECURITY BANCORPORATION PROFIT SHARING 401(k) PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS -------------------------------------------------------------------------------- DECEMBER 31, ------------------------ 2000 1999 --------- ---------- ASSETS Investments, at fair value Mutual funds $1,816,650 Common stocks $1,540,155 U.S. Treasury bonds 344,301 Money market fund 58,290 ---------- ---------- 1,816,650 1,942,746 ---------- ---------- Receivables Dividends and interest 9,638 Participants' contributions 29,034 9,682 ---------- ---------- 29,034 19,320 ---------- ---------- Cash 1,903 ---------- ---------- Total assets 1,845,684 1,963,969 LIABILITIES Accounts payable 203 ---------- ---------- NET ASSETS AVAILABLE FOR BENEFITS $1,845,684 $1,963,766 ========== ========== See accompanying notes. -------------------------------------------------------------------------------- 2 EXHIBIT 99.1 UNITED SECURITY BANCORPORATION PROFIT SHARING 401(k) PLAN STATEMENT OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS -------------------------------------------------------------------------------- YEAR ENDED DECEMBER 31, -------------------------------------- 2000 1999 1998 --------- ---------- ----------- ADDITIONS TO NET ASSETS ATTRIBUTED TO Investment income Net (depreciation) appreciation in fair value of investments $ (85,095) $ (48,445) $ 42,427 Interest and dividends 24,343 52,674 20,524 ---------- ---------- ---------- (60,752) 4,229 62,951 Less investment expenses (17,526) (25,200) (13,058) ---------- ---------- ---------- (78,278) (20,971) 49,893 ---------- ---------- ---------- Contributions Participants' 305,712 238,086 842,554 Rollovers from qualified plan 984 207,735 ---------- ---------- ---------- 306,696 445,821 842,554 ---------- ---------- ---------- Totals additions 228,418 424,850 892,447 DEDUCTIONS FROM NET ASSETS ATTRIBUTED TO Benefits paid to participants 346,500 421,026 76,115 ---------- ---------- ---------- INCREASE (DECREASE) IN NET ASSETS (118,082) 3,824 816,332 NET ASSETS AVAILABLE FOR BENEFITS Beginning of year 1,963,766 1,959,942 1,143,650 ---------- ---------- ---------- End of year $1,845,684 $1,963,766 $1,959,982 ========== ========== ========== See accompanying notes. -------------------------------------------------------------------------------- 3 UNITED SECURITY BANCORPORATION PROFIT SHARING 401(k) PLAN NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- Note 1 - Description of the Plan The following description of the United Security Bancorporation Profit Sharing 401(k) Plan (Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. During March 2001, United Security Bancorporation changed its name to AmericanWest Bancorporation (Note 6). General - The Plan is a defined contribution plan sponsored and administered by an outside third party. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan has two features: a profit sharing feature and a salary deferral feature, commonly known as a 401(k) plan. Participation and vesting - The Plan generally covers all full-time employees of United Security Bancorporation (Bancorporation) who have completed 1,000 hours of service and who have attained at least 18 years of age. Participants gain 20% vesting of the profit sharing each year after two completed years of service, and become 100% vested after six years of service. All 401(k) employee contributions are immediately 100% vested. Contributions - Profit sharing contributions are made from Bancorporation profits at the discretion of the Bancorporation. The 401(k) feature of the Plan allows participants to make contributions, through salary reduction, of 1% to 15% of their gross pay. No Bancorporation contributions were made during 2000, 1999 or 1998. Participant accounts - Each participant's account is credited with the participant's contribution and an allocation of (a) the Bancorporation's contribution, (b) Plan earnings, and (c) forfeitures of terminated participants' nonvested accounts. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Payment of benefits - Participants entitled to distributions due to retirement, death, disability, or termination of employment have the option of receiving a lump-sum payment or periodic payments which meet the requirements of the Internal Revenue Code. Plan termination - Although it has not expressed any intent to do so, the Bancorporation has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become fully vested in their accounts. -------------------------------------------------------------------------------- 4 UNITED SECURITY BANCORPORATION PROFIT SHARING 401(k) PLAN NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- Note 2 - Summary of Significant Accounting Policies Basis of accounting - The financial statements of the Plan are prepared under the accrual method of accounting. Investment valuation and income recognition - The Plan's investments are stated at fair value based on quoted market prices. Mutual funds are valued at the net asset value of shares held by the plan at year end. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Payments of benefits - Benefits are recorded when paid. Use of estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Risks and uncertainties - The Plan provides for various investment options in combinations of mutual funds and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits. Note 3 - Tax Status The Internal Revenue Service has determined and informed the Company by letter dated January 10, 1997 that the Plan and related trust are designed in accordance with the applicable requirements of the Internal Revenue Code. The Plan has been amended since receiving the determination letter. However, the plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable provisions of the Internal Revenue Code. -------------------------------------------------------------------------------- 5 UNITED SECURITY BANCORPORATION PROFIT SHARING 401(k) PLAN NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- Note 4 - Investments Individual investments that represent 5% or more of net assets available for benefits are as follows: 2000 1999 ---------- ---------- AIM Balance Fund A $ 112,282 AIM Basic Value Fund A $ 185,988 American Funds New Economy Fund A $ 240,479 American Funds Europacific Growth Fund A $ 242,151 AIM Blue Chip Fund A $ 273,242 AIM Aggressive Growth Fund A $ 315,512 AmericanWest Bancorporation common stock $ 495,863 During 2000, 1999 and 1998, the Plan's investments (including gains and losses on investment bought and sold, as well as held during the year) (depreciated) appreciated in value by $(85,095), $(48,448) and $42,427, respectively, as follows: YEARS ENDED DECEMBER 31, -------------------------------------- 2000 1999 1998 ---------- ---------- ---------- Mutual funds $ (42,612) Common stocks (42,483) $ (24,554) $ 34,832 U.S. Treasury bonds (23,891) 7,595 ---------- ---------- ---------- $ (85,095) $ (48,445) $ 42,427 ========== ========== ========== Note 5 - Related Party Transactions During 2000, 1999 and 1998, the Bancorporation paid and provided certain administrative and accounting fees on behalf of the Plan.
