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 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 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, 1999 and 1998, and the changes in net assets available for benefits for the years then ended in conformity with generally accepted accounting principles. 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 at 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. This 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, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Participants should refer to the Plan document for a more complete description of the Plan's provisions. (a) General The Plan is a defined contribution plan established for employees of Whidbey Island Bank (Sponsor) and the Bank's subsidiary, WIB Financial Services, Inc., who are at least 21 years of age and have completed one year of service, as defined by the Plan document. The Plan is subject to provisions of the Employee Retirement Income Security Act of 1974 (ERISA). (b) Administration The Sponsor is the Plan administrator and has appointed certain designated directors of the Sponsor to serve as trustees of the Plan. The assets of the Plan are held by Safeco Mutual Funds (Safeco), except Sponsor common stock which is held by Security Trust Company. (c) Contributions and Participants' Accounts Accounts are established for each participant and include the participant's contributions (including those rolled over from another qualified plan or trust),employer matching contributions, and any discretionary contributions from the Sponsor and earnings thereon. Participants may contribute up to 15% of pretax annual compensation, limited by the Internal Revenue Code to $10,000 in 1999 and 1998. The Sponsor's matching contribution is 50 cents for each dollar contributed on the first 5% of the participant's eligible compensation. The Sponsor may also make discretionary contributions at the option of the Sponsor's board of directors. There were no Sponsor discretionary contributions in 1999 or 1998. The Sponsor contributions are made in cash and allocated to a participant's account balance in accordance with the participant's contribution elections. Effective March 1, 2000, employees are eligible to make contributions on the first day of the month coincident with or following hire date and attaining age 21. Employees are eligible to receive matching and profit sharing contributions as of the January 1 or July 1 coincident with or following completion of one year of service and the attainment of age 21. 4 8 WHIDBEY ISLAND BANK 401(k) PLAN Notes to Financial Statements December 31, 1999 and 1998 (d) Investment Options Participants have the option of directing their contributions in 1% increments into any one or more of the Plan's investment fund options: Washington Banking Company Common Stock, Safeco International Stock Fund, Janus Worldwide Fund, Safeco Small Company Fund, Safeco Growth Fund, Safeco Northwest Fund, Neuberger & Berman Equity Fund, Janus Fund, Safeco Equity Fund, Scudder Growth & Income Fund, Safeco Income Fund, American Century Group Value Equity Income Fund, Safeco High Yield Bond Fund, Loomis Sayles Bond Fund, and Safeco Money Market Fund. Participants may change their investment options at anytime. (e) Vesting Participants are immediately vested in their contributions, Sponsor matching contributions and earnings thereon. Vesting of the Sponsor's discretionary contribution and actual earnings thereon is based on years of credited service of participants. The following schedule sets forth the vesting schedule: Years of vesting service Vested percent --------------------------------------------- ------------------- Less than 2 $ 0% --------------------------------------------- 2 20 --------------------------------------------- 3 40 --------------------------------------------- 4 60 --------------------------------------------- 5 80 --------------------------------------------- 6 100 --------------------------------------------- Participants become fully vested at the age of 65, upon the participant's death or upon permanent disability. Forfeitures of nonvested Sponsor contributions are allocated to remaining participants and treated as Sponsor non-elective contributions for the Plan year. Forfeited nonvested balances during 1999 and 1998 amounted to approximately $450 and $500, respectively. 5 9 WHIDBEY ISLAND BANK 401(k) PLAN Notes to Financial Statements December 31, 1999 and 1998 (f) Payment of Plan Benefits Participants may elect to have payments of vested benefits paid either in a lump sum or on an installment basis after their retirement or termination date. With approval of the Sponsor, early withdrawals may be paid by the Plan to those employees experiencing a financial hardship, as defined by the Plan. Distributions are paid in a single lump sum or, if the account balance exceeds $5,000 and at the participant's election, by payment in monthly, quarterly or annual installments over a fixed, reasonable period of time not to exceed the combined life expectancy of the participant and beneficiary. (g) Plan Expenses Expenses of the Plan are paid by the Sponsor and, therefore, are not included in the accompanying financial statements of the Plan. (h) Plan Termination Although it has not expressed an intent to do so, the Sponsor has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. Should the Plan be terminated at some future date, all participants would become fully vested in their account balances. (2) Summary of Significant Accounting Policies (a) Basis of Presentation and Accounting The Plan financial statements are presented on the accrual basis of accounting. (b) Valuation of Investments Investments are stated at fair value based on quoted market prices. Net appreciation or depreciation of investments includes both realized and unrealized gains and losses. Purchases and sales of securities are recorded on a trade-date basis. (c) Payment of Benefits Benefits are recorded when paid. 6 10 WHIDBEY ISLAND BANK 401(k) PLAN Notes to Financial Statements December 31, 1999 and 1998 (d) Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires the Plan administrator 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. (3) Tax Status The Internal Revenue Service has determined and informed the Sponsor by a letter dated October 26, 1994, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan has been amended since receiving the determination letter. However, the Plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. (4) Related Party Transactions Certain Plan assets are managed by Safeco and therefore, the related transactions qualify as party-in-interest transactions. (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. 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 is not presented in the Plan's financial statements. 7 11 WHIDBEY ISLAND BANK 401(k) Notes to Financial Statements December 31, 1999 and 1998 (6) Investments The following table presents the assets held for investment purposes at December 31: 1999 1998 -------------------------------- ---------------------------------- Principal Principal amount or amount or number of Investment number of Investment shares value shares value --------------- --------------- Money market funds - Safeco Money Market Fund 135,727 $ 135,727 134,988 $ 134,988 --------------- ---------------- Mutual funds: Safeco International Stock Fund 213 3,602 117 1,534 Janus Worldwide Fund 5,967 456,062 4,819 228,211 Safeco Small Company Fund 12,862 163,742 10,387 115,917 Safeco Growth Fund 24,890 579,946 22,550 511,881 Safeco Northwest Fund 11,014 278,986 7,515 133,235 Neuberger & Berman Equity Fund 2,094 50,257 1,469 37,461 Janus Fund 8,782 386,874 4,376 147,247 Safeco Equity Fund 6,826 163,983 7,119 165,520 Scudder Growth & Income Fund 5,690 151,883 4,773 125,573 Safeco Income Fund 678 15,185 501 11,770 American Century Group Value Equity Income Fund 1,247 6,986 529 3,337 Safeco High Yield Bond Fund 156 1,305 31 270 Loomis Sayles Bond Fund 483 5,568 -- -- --------------- ---------------- Total mutual funds 2,264,379 1,481,956 --------------- ---------------- Common stock -- Washington Banking Company 87,090 728,398 81,352 691,492 --------------- ---------------- Total investments $ 3,128,504 $ 2,308,436 =============== ================ 8 12 Schedule 1 WHIDBEY ISLAND BANK 401(k) PLAN Schedule of Assets Held for Investment Purposes December 31, 1999 Description of investment, including Identity of issue, borrower, maturity date, rate of interest, lessor, or similar party collateral, and par or maturity value Current value - -------------------------------------------------------- ------------------------------------------------- --------------- *Washington Banking Company Common Stock, 87,090 shares $ 728,398 *Safeco Mutual Funds International Stock Fund, 213 shares 3,602 Janus Equity Funds Janus Worldwide Fund, 5,967 shares 456,062 *Safeco Mutual Funds Small Company Fund, 12,862 shares 163,742 *Safeco Mutual Funds Growth Fund, 24,890 shares 579,946 *Safeco Mutual Funds Northwest Fund, 11,014 shares 278,986 Neuberger & Berman Funds Equity Fund, 2,094 shares 50,257 Janus Equity Funds Janus Fund, 8,782 shares 386,874 *Safeco Mutual Funds Equity Fund, 6,826 shares 163,983 Scudder Growth & Income Fund, 5,690 shares 151,883 *Safeco Mutual Funds Income Fund, 678 shares 15,185 American Century Group Value Equity Income Fund, 1,247 shares 6,986 *Safeco Mutual Funds High Yield Bond Fund, 156 shares 1,305 Loomis Sayles Loomis Sayles Bond Fund, 483 shares 5,568 *Safeco Mutual Funds Money Market Fund, 135,727 shares 135,727 *A party-in-interest, as defined by Section 3(14) of ERISA 9 13 EXHIBITS 23.1 Consent of Independent Accountants SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the trustee or other persons who administer the employee benefit plan have duly caused this annual report to be signed on its behalf by the undersigned, hereunto duly authorized.
