JNL MONEY MARKET FUND (UNAUDITED) NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) JNL MONEY MARKET FUND (UNAUDITED) NOTES TO THE FINANCIAL STATEMENTS NOTE 1. ORGANIZATION JNL Investors Series Trust (the "Trust") was organized under the laws of Massachusetts, by a Declaration of Trust, dated July 28, 2000. The Trust is registered with the Securities and Exchange Commission under the Investment Company Act of 1940 (the "1940 Act"), as amended, and the Securities Act of 1933, as amended, as an open-end management investment company issuing its shares in series, each series representing a distinct portfolio with its own investment objectives and policies. The JNL Money Market Fund (the "Fund") is presently the only series authorized. The Fund is a "diversified" series of the Trust and is sub-advised by Wellington Management Company, LLP. The Fund commenced operations on November 1, 2005. The Institutional Class of shares is the only class of shares presently being offered by the Fund. Jackson National Asset Management, LLC ("JNAM"), a wholly-owned subsidiary of Jackson National Life Insurance Company ("Jackson National"), serves as investment adviser to the Fund. NOTE 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed and consistently applied by the Trust in the preparation of its financial statements. 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 and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. GUARANTEES AND INDEMNIFICATIONS - Under the Fund's organizational documents, its officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, certain of the Fund's contracts with its service providers contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined and the Fund has no historical basis for predicting the likelihood of any such claims. SECURITY VALUATION - Pursuant to Rule 2a-7 of the 1940 Act, securities in money market funds are valued at amortized cost, which approximates market value, in order to maintain a constant net asset value of $1.00 per share. If amortized cost no longer approximates market value due to credit or other impairments of the issuer, the Fund will use Board approved pricing and valuation procedures to determine a security's fair value. Money market funds must invest exclusively in high quality securities. To be considered high quality, a security generally must be rated in one of the two highest short-term credit quality categories by a nationally recognized rating organization such as Standard & Poors Corporation or Moody's Investors Service, Inc. SECURITY TRANSACTIONS AND INVESTMENT INCOME - Security transactions are recorded on trade date. Dividend income is recorded on ex-dividend date. Interest income, including straight line amortization of discounts and premiums, is accrued daily. Realized gains and losses are determined on the specific identification basis. REPURCHASE AGREEMENTS - The Fund may invest in repurchase agreements. A repurchase agreement involves the purchase of a security by a Fund and a simultaneous agreement (generally by a bank or broker-dealer) to repurchase that security back from the Fund at a specified price and date or upon demand. Securities pledged as collateral for repurchase agreements are held by the Fund's custodian bank until the maturity of the repurchase agreement. Procedures for all repurchase agreements have been designed to assure that the daily market value of the collateral is in excess of the repurchase agreement in the event of default. DISTRIBUTIONS TO SHAREHOLDERS - The Fund declares dividends daily and pays dividends monthly. Distributions of net realized capital gains, if any, will be distributed at least annually. FEDERAL INCOME TAXES - The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code necessary to qualify as a regulated investment company and to make the requisite distributions of taxable income and capital gains to it's shareholders sufficient to relieve it from all or substantially all federal income or excise taxes. NOTE 3. INVESTMENT ADVISORY FEES AND TRANSACTIONS WITH AFFILIATES The Trust has entered into an Investment Advisory Agreement (the "Agreement") with JNAM whereby JNAM provides investment management services to the Fund. Under the terms of the Agreement, the Fund pays JNAM an annual fee, computed daily and payable monthly, based on a specified percentage of the average daily net assets of the Fund. A portion of this fee is paid by JNAM to the sub-adviser as compensation for their services. The following is a schedule of the fees the Fund is currently obligated to pay JNAM. ASSETS FEES $0 to $750 million 0.20% Over $750 million 0.18% ADMINISTRATIVE SERVICES - JNAM provides or procures most of the necessary administrative functions and services for the operations of the Fund at no additional cost to the Institutional class of shares. In accordance with the Administration Agreement, JNAM is responsible for payment of expenses related to legal, audit, fund accounting, custody, printing and mailing and other services necessary for the operation of the Fund. The Fund is responsible for expenses including brokerage commissions, interest and taxes, other non-operating expenses, registration fees, Trustees and officers insurance, the fees and expenses of the disinterested Trustees and independent legal counsel to the disinterested Trustees and a majority of the cost associated with the Chief Compliance Officer. TRANSFER AGENCY SERVICES - The Trust has an agreement with JNAM whereby JNAM provides transfer agency services for the Institutional Class of shares of the Fund at no additional cost. NOTE 4. FEDERAL INCOME TAX MATTERS As of April 30, 2006, the aggregate cost of investments and the composition of unrealized appreciation and depreciation of investments for federal income tax purposes are listed in the following table (in thousands). Cost of Investments Gross Unrealized Appreciation Gross Unrealized Depreciation Net Unrealized Appreciation - ------------------- ----------------------------- ------------------------------ --------------------------- $ 216,708 $ - $ - $ - The tax character of distributions paid during the semi-annual period ended April 30, 2006, were as follows (in thousands): Ordinary Income - --------------- $ 4,771 DISCLOSURE OF FUND EXPENSES (UNAUDITED) The Fund is affected by ongoing costs, which include (among others) costs for portfolio management, administrative services, and the operating expenses. Operating expenses such as these are deducted from the Fund's gross income and directly reduce the final investment return. These expenses are expressed as a percentage of the Fund's average net assets; this percentage is known as the Fund's expense ratio. The examples below include the expense ratio and are intended to help the investor understand the ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other Mutual Funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. ACTUAL FUND RETURN. This section provides information about the actual account values and actual expenses incurred by the Fund. Use the information in this section, together with the amount invested, to estimate the expenses the shareholder paid over the period. Simply divide the account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled "Expenses paid During Period" to estimate the expenses paid during this period. HYPOTHETICAL 5% RETURN. The information in this section can be used to compare each Fund's costs with those of other mutual funds. It assumes that the Fund had an annual 5% return before expenses during the year, but that the expense ratio for the period is unchanged. This example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to make the 5% calculation.

A description of the policies and procedures used by the Funds to vote proxies relating to the portfolio securities and information on how the Funds voted proxies relating to portfolio securities during the 12 month period ended June 30, 2005 are available (1) without charge, upon request by calling 1-800-766-4683 (Annuity Service Center), 1-800-599-5651 (NY Annuity Service Center) or 1-800-777-7779 (for contracts purchased through a bank or financial institution), (2) on Jackson National Life Insurance Company's website at WWW.JNL.COM or Jackson National Life Insurance Company of New York's website at WWW.JNLNY.COM, and (3) on the SEC's website at WWW.SEC.GOV. JNL INVESTORS SERIES TRUST (THE "TRUST") TRUSTEES' CONSIDERATION OF INVESTMENT ADVISORY AND SUB-ADVISORY AGREEMENTS Under the Investment Company Act of 1940 (the "1940 Act"), an investment advisory or sub-advisory contract initially must be approved by a vote of the majority of the outstanding voting securities of the investment company which, in the case of a newly organized Fund (the JNL Money Market Fund, hereinafter referred to as the "Fund"), may be a vote by the sole initial shareholder, and may continue in effect for a period longer than two years from the date of its execution only so long as continuance is specifically approved at least annually by the Board of Trustees (the "Trustees") or by a vote of the majority of the outstanding voting securities of the investment company. Further, the 1940 Act requires that an investment advisory or sub-advisory agreement, or the continuance thereof, be approved by a vote of the majority of the disinterested Trustees cast in person at a meeting called for the purpose of voting on such approval. The 1940 Act also places a specific duty upon the Trustees to request and evaluate, and a corresponding duty upon the investment adviser or sub-adviser to furnish, such information as reasonably may be necessary to evaluate the terms of the agreement. The Trustees are presented at each of their regular meetings with reports and analyses by Jackson National Asset Management LLC ("JNAM" or the "Adviser") and the sub-advisers on a number of matters, including (i) the investment performance of the Fund of the Trust, in relation to benchmark indices and in relation to other funds having similar investment objectives; (ii) Fund brokerage; and (iii) portfolio compliance matters. In addition to submitting quarterly written reports regarding the Fund under their management, portfolio management representatives of the Trust's sub-adviser also make in-person reports to the Trustees on a regular basis. The Trustees review and consider these reports and presentations as part of their responsibility to manage the affairs of the Trust. These reports and presentations also form a part of the information considered by the Trustees in determining whether to approve the continuation of the agreements with the Adviser and the sub-adviser. Described below is a summary of certain information provided to and considered by the Trustees, and their conclusions with respect thereto, that contributed to the Trustees' decision to approve of the current investment advisory and sub-advisory agreements of the Trust. INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT WITH THE ADVISER The current Investment Advisory and Management Agreement between the Trust and the Adviser contemplates a "manager of managers" structure whereby the Adviser, with the approval of the Trustees but without necessity of obtaining shareholder approval, may select, retain and compensate the sub-adviser for the Fund, or materially amend agreements with sub-advisers. The Adviser and the Trust have been granted an exemption by the SEC. The "manager of managers" structure was approved by the Trustees at a meeting held December 13, 2001. The form of the Investment Advisory and Management Agreement with the Adviser's predecessor, JNFS, was approved by the Trustees at a meeting held August 10, 2000. The agreement with the Adviser was approved by the shareholders of the Fund, and became effective as of January 31, 2001. At a shareholder meeting of the Trust held July 11, 2005, the shareholders of all Funds approved this multi-manager structure. At its meeting on August 31, 2005, the Trustees, including a majority of the Independent Trustees, considered the commencement of operations of the Fund. The Trustees were presented by the Adviser with information regarding: (1) the nature, quality and extent of its services, (2) the investment performance of the Trust, (3) its profitability, including an analysis of the cost of providing services and comparative expense information, (4) the extent to which economies of scale are realized as the Trust grows and whether fee levels reflect these economies of scale for the Trust's investors, and (5) other "fall-out" benefits realized by JNAM (i.e. ancillary benefits derived by JNAM or its affiliates from JNAM's relationship with the Trust). NATURE, QUALITY AND EXTENT OF SERVICES The Trustees examined the nature, quality and extent of the services to be provided by the Adviser to the Fund. The Trustees reviewed information on the Adviser's key personnel that will be providing investment advisory services to the Fund, including responsibilities for serving as the Fund's administrator and transfer agent, overseeing the Fund's sub-adviser, monitoring adherence to the Fund's investment restrictions and monitoring compliance with various policies and procedures of the Fund. The Trustees concluded that there was a reasonable basis on which to conclude that the Fund would benefit from the services provided by the Adviser under their Agreements as a result of their experience, reputation, personnel, operations and resources. INVESTMENT PERFORMANCE OF THE FUND The Trustees considered information provided by the Adviser on the performance of the Fund, including comparative performance information. The composite performance information provided by the Sub-adviser exceeded the Fund's benchmark performance (gross of fees) for all periods shown. COSTS OF SERVICES AND PROFITS REALIZED BY THE ADVISER The Trustees examined the advisory fee and expense information for the Fund as compared to comparable funds managed by other advisers. The Fund's investment management fee of 0.20% is below the Lipper median management fee of 0.35%. Overall expenses of the Fund of 0.20% also compare favorably to the Lipper median of 0.30%. The Board considered the performance of the Fund and the Sub-adviser and the performance of the other funds managed by the Sub-adviser, including comparative performance information. Fund operations commenced November 1, 2005. ECONOMIES OF SCALE The Trustees considered the extent to which the Fund's advisory fees reflect economies of scale for the benefit of Fund's shareholders. The Trustees reviewed the Fund's fee arrangements, which include breakpoints that decrease the fee rate as the Fund's assets increase. The Trustees concluded that the breakpoints in the Adviser's contracts with the Fund, would share with shareholders the benefits of economies of scale as the Fund's assets grow. The Trustees concluded that, under the Agreements, shareholders would share in the benefits to be achieved through economies of scale. OTHER BENEFITS TO THE ADVISER AND ITS AFFILIATES In evaluating the benefits that accrue to the Adviser, the Trustees reviewed all of the JNL Funds as a whole, including the Fund of the JNL Investors Series Trust. Through its relationship with the Fund, the Trustees recognized that the Adviser, and its affiliate, Jackson National Life Distributors, Inc. ("JNLD"), serve the Fund in various capacities, including as Adviser, administrator, transfer agent and distributor, and receive compensation from the Fund in connection with providing certain of these services to the Fund. As administrator, the Adviser receives a fee for providing fund accounting and administration services to the Fund (except the Institutional Class of the Fund). This fee also is used by the Adviser to cover most of the Fund's operating expenses. The Trustees also review the Administrative Fee annually. JNAM does not receive a fee from the JNL Funds and the Institutional Class of the Fund for its transfer agent services. As distributor, JNLD receives a 0.20% 12b-1 fee from the Fund (except for the S&P Funds and the JNL Money Market Fund). After full consideration of these and other factors, the Trustees, including a majority of the Independent Trustees, concluded that approval of the Agreements were in the best interest of the Fund and its shareholders. SUB-ADVISORY AGREEMENT WITH WELLINGTON MANAGEMENT COMPANY, LLP At its meeting on August 31, 2005, the Trustees of the Fund, including a majority of the Independent Trustees, considered and approved the Fund's investment sub-advisory agreement with Wellington Management Company, LLP (the "Sub-adviser") through June 30, 2007 (the "Agreement"). In considering the Agreement, the Trustees reviewed and analyzed the factors it deemed relevant, including: (1) the nature, quality and extent of the Sub-adviser's services, (2) the investment performance of the Fund, including information comparing the performance of the Fund with a peer group of funds and an appropriate index, (3) the profitability of the Sub-adviser, including an analysis of the Sub-adviser's cost of providing services and comparative expense information, and (4) the extent to which economies of scale are realized as the Fund grows and whether fee levels reflect these economies of scale for Fund investors. The Trustees also periodically consider other material facts such as the allocation of the Fund's brokerage commissions and the Fund's record of compliance with its investment policies and restrictions on personal securities transactions. Before approving the Agreement, the Board's Independent Trustees met in executive session with their independent counsel to consider the materials provided by the Adviser and the Sub-adviser and the terms of the Agreement. Based on its evaluation of information provided by the Sub-adviser, the Trustees, including a majority of the Independent Trustees, concluded that the Agreement is fair and in the best interests of shareholders. During its deliberations, the Trustees balanced the various factors based on all the facts and circumstances applicable to the sub-advisory relationship. The following summary does not detail every matter considered. In reaching its conclusion, the Trustees considered the following: NATURE, QUALITY AND EXTENT OF SERVICES The Trustees examined the nature, quality and extent of the services provided by the Sub-adviser to the Fund. The Trustees reviewed the Sub-adviser's key personnel in providing investment management services to the Fund. The Trustees also considered the Sub-adviser's duties under the Agreement in serving as the Fund's investment Sub-adviser including duties for investment research and security selection, adherence to the Fund's investment restrictions and monitoring compliance with various Fund policies and procedures. While recent legal and regulatory issues at the Sub-adviser are cause for concern, and require increased scrutiny by JNAM and the Trustees, the Trustees concluded that the Fund benefits from services provided by the Sub-adviser under the Agreement, as a result of the Sub-adviser's management and operational changes, portfolio management and investment experience, past performance, fee structure, and extensive resources. INVESTMENT PERFORMANCE OF THE SUB-ADVISER AND THE FUND The Trustees considered composite information, which showed performance of Sub-Adviser's Money Market Composite and its benchmark. On a gross of fee basis, the Sub-adviser out-performed its benchmark over all periods. The Trustees concluded it was in the best interest of the Fund and its shareholders to approve the Agreement. COSTS OF SERVICES AND PROFITS REALIZED BY THE SUB-ADVISER The Trustees examined the sub-advisory fee and expense information for the Fund as compared to comparable funds managed by other advisers, in addition to its Lipper average. The Trustees noted that the Fund's sub-adviser fee of 0.05% is below the Lipper average of 0.09%. The Trustees noted that the Fund's sub-advisory fee is reasonable. ECONOMIES OF SCALE The Trustees considered the extent to which the Fund's sub-advisory fee reflects economies of scale for the benefit of Fund shareholders. The Trustees reviewed the Fund's fee arrangements, which include breakpoints that decrease the fee rate as the Fund's assets increase. The Trustees concluded that the breakpoints shared with JNAM and that JNAM in turn, through the breakpoints in its contract with the Fund, shares with shareholders the benefits of economies of scale as the Fund's assets grow. In light of this, the Trustees noted that it would be reasonable to conclude that under the Agreement, shareholders share in the benefits to be achieved through economies of scale. OTHER BENEFITS TO THE SUB-ADVISER AND ADVISER Wellington Management Company, LLP is sub-adviser to other funds advised by JNAM. In evaluating the benefits that accrue to the Sub-adviser, the Trustees reviewed the Fund as a whole, including the benefits accruing to the Adviser who identifies and recommends the Sub-adviser to the JNLIST. Through its relationship with the Fund, the Trustees recognized that the Sub-Adviser and its affiliate serve the Fund in various capacities. After full consideration of these and other factors, the Trustees, including a majority of the Independent Trustees, concluded that approval of the Agreement was in the best interest of the Fund and its shareholders.
