Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan covering substantially all full-time employees of Timberland Bank (the Company) who have one year of service and are age twenty-one or older. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Company is the wholly owned subsidiary of Timberland Bancorp, Inc. Contributions and Participant Investment Options The Plan participants may contribute up to the maximum of pretax annual compensation as set by law. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Company makes an annual safe harbor contribution of 3% of eligible compensation, with additional amounts contributed at the option of its board of directors. For the year ended September 30, 2005, the Board of Directors authorized a 7% profit sharing contribution of total eligible participant compensation in addition to the safe harbor contribution. Participants must direct their salary deferral contributions and their allocated share of the safe harbor contribution and the employer contributions, if any, into a variety of investment choices, as made available and determined by the Plan administrator, which are more fully described in the Plan's literature. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of: (a) the Company's contributions, (b) Plan earnings, and (c) forfeitures of terminated participants' nonvested accounts and charged with an allocation of administrative expenses. 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. Vesting Participants are immediately vested in all deferral, rollover and safe harbor contributions, plus actual earnings thereon. Vesting in the Company's discretionary contribution portion of accounts, plus earnings thereon, is based on years of credited service. Participants are fully vested after six years of credited service. A participant's accrued benefit derived from employer contributions is also 100% nonforfeitable upon attaining age 65, or if the participant's separation from service is a result of death or disability. (continued) 5 Notes to Financial Statements ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan September 30, 2005 and 2004 Note 1 - Description of the Plan (concluded) Payment of Benefits On termination of service, a participant with an accrued benefit of $5,000 or less will receive a lump-sum amount equal to the value of the vested interest in their account. The distribution date will be the earliest administratively feasible date for participants that attain normal retirement age or age 55 with 10 years of service. Distributions for participants that do not meet these requirements will be made as soon as administratively feasible in the Plan year following separation of service. Participants with an accrued benefit in excess of $5,000 may leave the funds in the Plan or elect to receive a lump-sum distribution. Forfeited Accounts Forfeited balances of terminated participant nonvested accounts are treated as discretionary contributions for the Plan year in which the forfeitures occur. Forfeitures allocated for the year ended September 30, 2005 totaled $27,096. Note 2 - Summary of Accounting Policies Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and the disclosure of contingent assets and liabilities. Actual results could differ from these estimates. Investment Valuation and Income Recognition The Plan's investments are stated at fair value. Quoted market prices are used to value common stock and mutual funds. Shares of 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 the trade-date basis. Dividends are recorded on the ex-dividend date. Payment of Benefits Benefits are recorded when paid. 6 Notes to Financial Statements ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan September 30, 2005 and 2004 Note 3 - Investments The following presents, separately, identified investments that represent 5% or more of the Plan's net assets at September 30: 2005 2004 Timberland Bancorp, Inc. Common Stock $3,810,338 $4,345,658 Mutual Funds First American Small Cap Growth Fund 669,160 758,499 First American Strategy Growth Allocation Fund 675,099 732,259 First American Equity Index Fund 508,579 564,923 First American Prime Obligations Fund 632,186 474,973 First American Strategy Aggressive Allocation Fund 586,755 375,360 $6,882,117 $7,251,672 During 2005 the Plan's investments, including gains and losses on investments bought and sold, as well as held during the year, appreciated in value by $349,773 as follows: Mutual funds $402,770 Common stock (52,997) Net appreciation in fair value of investments $349,773 Note 4 - Plan Termination Although it has not expressed any intent to do so, the Company 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 100% vested in their accounts. Any unallocated assets of the Plan shall be allocated to participant accounts and distributed in such a manner as the Company may determine. 7 Notes to Financial Statements ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan September 30, 2005 and 2004 Note 5 - Tax Status/Non-Standardized Prototype Plan Effective October 1, 1997, the Plan adopted a nonstandardized form of a prototype plan sponsored by Actuarial Planning Group, Inc. The prototype plan received an opinion letter, dated August 30, 2001, from the Internal Revenue Service which stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. The Plan has been amended subsequent to receiving the opinion letter. However, the Plan administrator believes the Plan is designed and is being operated in compliance with the applicable provisions of the Internal Revenue Code. Note 6 - Administration of Plan Assets Certain Plan investments are shares of mutual funds managed by US Bank. US Bank is the trustee, as defined by the Plan; therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan for investment management services amounted to $28,413 for the year ended September 30, 2005. Certain administrative functions of the Plan are performed by officers or employees of the Company. No such officers or employees receive compensation from the Plan. Other administrative and management fees of the Plan are paid directly by the Company. Note 7 - Risks and Uncertainties The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term, and that such changes could materially affect participant account balances and the amounts reported on the statements of net assets available for benefits. Note 8 - Recent Regulatory Guidance Effective March 28, 2005 the Department of Labor (DOL) amended the Internal Revenue Code to comply with new regulations of the Economic Growth and Tax Relief Reconciliation Act of 2001. The amendment requires that mandatory distributions by the plan for vested balances of more then $1,000 and up to $5,000 be directly transferred to an individual retirement account (IRA) when a terminated retirement plan participant does not elect to take a distribution or make a rollover. The amendment requires all plans with "cash-outs" be amended by the last day of the plan year that begins on or after March 28, 2005. The Plan is in the processing of being amended to comply with the new regulation. 8 Supplemental Schedule Schedule of Assets (Held at End of Year) ------------------------------------------------------------------------------ Timberland Bank 401(k) Profit Sharing Plan September 30, 2005 EIN: 91-0260220 Plan Number: 001 (a) and (b) (c) (d) (e) Identity of Issue, Description of Investment, Including Cost Current Borrower, Lessor Maturity Date, Rate of Interest, Value or Similar Party Collateral, Par or Maturity Value (pv or mv) ** US Bank First American Strategy Aggressive Allocation Fund * $ 586,755 ** US Bank First American Prime Obligations Fund * 632,186 ** US Bank First American Equity Index Fund * 508,579 ** US Bank First American Strategy Growth Allocation Fund * 675,099 ** US Bank First American Small Cap Growth Fund * 669,160 ** Timberland Bancorp, Inc.
