REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees Jack Henry & Associates, Inc. 401(k) Retirement Savings Plan: We have audited the accompanying statements of net assets available for benefits of Jack Henry & Associates, Inc. 401(k) Retirement Savings Plan (the "Plan") as of December 31, 2005 and 2004 and the related statement of changes in net assets available for benefits for the year ended December 31, 2005. 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 standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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 present fairly, in all material respects, the net assets available for benefits of Jack Henry & Associates, Inc. 401(k) Retirement Savings Plan as of December 31, 2005 and 2004, and the changes in its net assets available for benefits for the year ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule 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 is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audit of the basic 2005 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/ DELOITTE & TOUCHE LLP St. Louis, Missouri June 22, 2006

JACK HENRY & ASSOCIATES, INC. 401(k) RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS AS OF DECEMBER 31, 2005 AND 2004 AND FOR THE YEAR ENDED DECEMBER 31, 2005 ---------------------------------------------------------------------------- 1. DESCRIPTION OF PLAN The following description of Jack Henry & Associates, Inc. 401(k) Retirement Savings Plan (the "Plan") provides only general information. Participants should refer to the Plan Agreement for a more complete description of the Plan's provisions. General-The Plan is a defined contribution, 401(k) plan covering employees of Jack Henry & Associates, Inc. (the "Company") who have attained the age of 18. To be eligible to receive the Company match and discretionary contribution employees must complete six months of service. The Company is the Plan Administrator and has appointed a trustee to hold and invest Plan assets. Diversified Investment Advisors is the Plan administrator and Investor's Bank and Trust is the Plan trustee. The Plan is subject to the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended. Investments-Participants direct the investment of their contributions and employee contributions into various investment options offered by the Plan. The Plan currently offers Jack Henry & Associates, Inc. common stock, a money market fund, fourteen mutual funds, and a guaranteed separate account fund as investment options for participants. Contributions-Participants may contribute up to the maximum contribution allowable under section 401(k) of the Internal Revenue Code. The Company matches 100% of participant contributions up to a maximum match of the lessor of 5% of the participant's annual compensation or $5,000. The total amount which a participant could elect to contribute to the Plan on a pre-tax basis in 2005 could not exceed $14,000. However, in 2005, if a participant reached age 50 by December 31, 2005, they were able to contribute an additional $4,000 "catch up" contribution to the Plan on a pre-tax basis. In addition, the Company may make a special discretionary contribution. The amount of the discretionary contribution is determined by the Company. Participants must have 1,000 hours of service during the year to share in any discretionary contributions. There were no discretionary contributions in 2005. Vesting-Participants are immediately vested in their voluntary contributions, the employer's matching contribution and the earnings on these contributions. Vesting in the employer's discretionary portions of their accounts is based on years of continuous service with an employee vesting 20% after two years of service and subsequently vesting 20% each year until becoming fully vested with six years of continuous service. Benefits-Upon termination of service due to death, disability, or retirement, a participant may elect to receive a lump-sum amount equal to the value of his or her account at either the time of termination or at the end of the Plan year. An employee may also elect to receive the value of his or her account in installment payments or have the balance rolled over into an Individual Retirement Account. Participant Loans-Participants may borrow for qualifying reasons as defined in the Plan, from their fund accounts a minimum amount of $1,000 up to a maximum of, the lesser of $50,000 less the amount of highest outstanding loan balance in the previous 12 months or 50% of their vested account balances. Loan terms range from one to five years, unless the loan is going to be used to purchase the participant's principal residence, in which case the term may extend beyond five years. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with local prevailing rates (ranging from 4.25% to 12.15% as of December 31, 2005), as determined by the Plan administrator. Principal and interest are paid through payroll deductions. Participants may elect to maintain their loan subsequent to their termination. Benefits Payable-Benefits are recorded when paid. As of December 31, 2005 and 2004, distributions payable to Plan participants was zero. Forfeited Accounts-At December 31, 2005 and 2004, forfeited nonvested accounts totaled $14,600 and $5,934, respectively. These accounts will be used first as restoration of participant's forfeitures, then as offset to Plan expenses, then as a reduction to future discretionary contributions. 2. SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting-The financial statements of the Plan are prepared on the accrual basis. Investment Valuation and Income Recognition-Investments are stated at fair value, which is determined using public market quotations if available. Non-publicly traded investments (Diversified Investment Advisors-Managed Stability-Stable 5 Fund) have been reported based on values provided by the Plan trustee. Participant loans are reported at cost, which approximates fair value. The Plan invests in various securities including common stock and mutual funds. Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for plan benefits. 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. Basis of Allocation-Investment income and gain or loss on investments are allocated to the participants based on the participant's account balance. Discretionary contributions, if any, are allocated based on eligible compensation. Unless directed otherwise by participants, employer matching and discretionary contributions will be allocated in the same manner as employee contributions. 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 net assets available for benefits and changes therein. Actual results could differ from those estimates. The Plan utilizes various investment instruments. Investment securities, in general, are exposed to various risk, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements. 3. INVESTMENTS The Plan's deposits are maintained in money market accounts until the deposits are allocated to the participant-directed funds based on the participant's percentage allocation election. The participant can elect direction of investments upon entering the Plan and may change the direction of investment options on a daily basis. The components of the Plan's individual investments which represent 5% or more of the Plan's net assets available for benefits at December 31, 2005 and 2004, are as follows: 2005 2004 Common stock-Jack Henry & Associates, Inc. $24,855,161 $25,257,656 Diversified Investment Advisors - Equity Growth Fund 14,273,286 12,678,838 Diversified Investment Advisors - Growth and Income Fund 12,720,071 10,978,024 Diversified Investment Advisors - Managed Stability - Stable 5 Fund 11,119,773 8,543,608 Diversified Investment Advisors - Value and Income Fund 7,830,626 5,195,406 During 2005, the Plan's investments (including gains and losses on investments bought, sold, as well as held during the year) appreciated (depreciated), as follows: Diversified Investment Advisors - Equity Growth Fund $ 925,585 Diversified Investment Advisors - Growth and Income Fund 597,118 Diversified Investment Advisors - Special Equity Fund 333,046 Diversified Investment Advisors - Value and Income Fund 301,408 Diversified Investment Advisors - International Equity Fund 281,115 Diversified Investment Advisors - Long Horizon Strategic Allocation Fund 251,568 Diversified Investment Advisors - Intermediate/Long Horizon Strategic Allocation Fund 119,433 Diversified Investment Advisors - Midcap Value Fund 117,864 Diversified Investment Advisors - Stock Index Fund 98,454 Diversified Investment Advisors - Intermediate Horizon Strategic Allocation Fund 44,355 Diversified Investment Advisors - Short/Intermediate Horizon Strategic Allocation Fund 8,272 Diversified Investment Advisors - Short Horizon Strategic Allocation Fund (13,347) Diversified Investment Advisors - Intermediate Government Bond Fund (27,392) Diversified Investment Advisors - Core Bond Fund (48,314) Common stock-Jack Henry & Associates, Inc. (772,569) ---------- $ 2,216,596 ========== 4. TRANSACTIONS WITH PARTIES-IN-INTEREST During 2005, the Plan received approximately $235,480 in dividends from the Company. In addition, the Company pays certain fees on behalf of the Plan for accounting services. 5. PLAN TERMINATION Although it has not expressed an intention 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, employees become 100% vested in their accounts. 6. TAX STATUS Effective July 1, 2002, the Plan adopted the Diversified Investment Advisors, Inc. 401(k) profit sharing prototype plan document. Diversified Investment Advisors, Inc.'s plan document received a favorable Internal Revenue Service opinion letter on July 29, 2004. The plan administrator believes that the Plan, as adopted, is designed and is being operated in compliance with applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. 7. PLAN MERGER Effective January 1, 2005, all participants in a 401(k) Savings Plan sponsored by TWS Systems, Inc. became participants in the Plan. TWS Systems, Inc. was acquired by the Plan Sponsor during 2004. After May 1, 2005, the total account balance of each participant in the TWS Systems, Inc. 401(k) Savings Plan was transferred to the Plan. * * * * * *
