Although it seeks to maintain a constant share price of $1.00, it is possible to lose money by investing in the fund. Management Discussion - -------------------------------------------------------------------------------- For the six months ended December 31, 2006, IXIS Cash Management Trust -- Money Market Series maintained a constant price of $1.00 per share and provided a total return of 2.36% based on the net asset value of Class A shares and $0.0234 per share in reinvested dividends. The fund's seven-day SEC yield at the end of the period was 4.67%. After raising the federal funds rate in 0.25% increments 17 times since 2004, the Federal Reserve Board paused following its June 2006 rate hike. (The fed funds rate is the rate banks charge one another on overnight loans, and is the only rate the Fed controls directly.) As a result, at the start of the fund's fiscal year on July 1, 2006, the fed funds rate was 5.25%, up from a low of 1% in June 2004. Since then the fed funds rate has remained steady. The Fed uses interest rates as a tool to keep inflation under control. The fed funds rate is critical to money market investors because it directly influences yields on money market securities as well as borrowing costs in other parts of the economy. FED PAUSES IN ITS SERIES OF RATE INCREASES During the first half of the fund's fiscal year, the Fed stood on the sidelines, leaving short-term interest rates unchanged as they monitored economic activity. The U.S. economy grew at a moderate pace during the six-month period, slowing slightly from earlier in the year. A significant correction in the formerly red-hot housing market, combined with record-high gas prices, contributed to the slowdown. This hands-off approach stood in sharp contrast to earlier periods. Many observers believe that Fed Chairman Ben Bernanke deserves much credit for not taking interest rates higher, as many were suggesting earlier in 2006 when inflation stood at 4% by some measures. It has since fallen to about 2%. Under Mr. Bernanke's guidance, the economy now appears to be on safe footing, with inflation under control. FUND'S AVERAGE MATURITY REMAINED IN THE MID RANGE Our strategy during the six months ended December 31, 2006 remained consistent with our approach in fiscal 2006. We worked to generate as much income as possible while maintaining flexibility in the portfolio to capture higher rates should they become available. With this in mind, we kept average maturity in the one- to three-month range. This approach helped us to pick up some additional yield without locking us into longer-term securities. At the start of the fund's fiscal year in July, the fund's average maturity stood at 46 days, compared with 43 days as of December 31, 2006. FUND IS FOCUSED ON COMMERCIAL PAPER Commercial paper remains the primary focus of the fund's portfolio. These securities - issued by companies rather than the U.S. government - tend to offer higher yields than other types of money market instruments with only minimal additional risk, especially on the shorter end of the maturity spectrum. In addition, a combination of variable-rate demand instruments and floating-rate notes accounted for approximately 21% of total assets. Yields on these securities rise and fall with changes in short-term interest rates. Although rates remained relatively steady, we maintained a substantial portion of assets in these securities in anticipation of possible rate hikes in the future. During periods of economic uncertainty, we tend to favor government and agency securities because of their relative safety. However, since the economy appears to be on safe footing, we believe credit downgrades will be less likely than they are during more turbulent times. This makes us feel comfortable shifting to a slightly more aggressive pursuit of current income. INFLATION IS KEY TO INTEREST-RATE FORECAST The current consensus among investment professionals is that the U.S. economy will avoid the recession that was once feared, with growth likely to stay slightly above 2% through mid-2007. 1 IXIS CASH MANAGEMENT TRUST -- MONEY MARKET SERIES - -------------------------------------------------------------------------------- Today's economic outlook argues for keeping interest rates steady. Although economic growth could be considered a bit anemic, it doesn't pose an inflation risk, which is the Fed's primary concern. Of course, all future Fed moves are data dependent. The Fed will be carefully monitoring economic statistics, business figures, and global news, and keeping a watchful eye on inflation prospects. We are taking a wait-and-see approach as well, maintaining relatively short maturities and monitoring both the economy and the Fed's actions closely, to determine our course of action. Our current focus is on value as well as current income - keeping average maturity on the shorter side - to capture yields without sacrificing flexibility. This should help us maintain our ability to move quickly to lock in higher rates when the opportunity seems right.

NOT FDIC INSURED MAY LOSE VALUE NO BANK GUARANTEE 3 UNDERSTANDING FUND EXPENSES As a mutual fund shareholder, you incur different costs: transaction costs and ongoing costs, including management fees and other fund expenses. In addition, the fund assesses a minimum balance fee of $20 on an annual basis for accounts that fall below the required minimum to establish an account. Certain exceptions may apply. These costs are described in more detail in the fund's prospectus. The examples below are intended to help you understand the ongoing costs of investing in the fund and help you compare these with the ongoing costs of investing in other mutual funds. The first line in the table for each Class of fund shares shows the actual account values and actual fund expenses you would have paid on a $1,000 investment in the fund from July 1, 2006 through December 31, 2006. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example $8,600 account value divided by $1,000 = 8.6) and multiply the result by the number in the Expenses Paid During Period column as shown below for your Class. The second line in the table for each Class of fund shares provides information about hypothetical account values and hypothetical expenses based on the fund's actual expense ratios and an assumed rate of return of 5% per year before expenses, which is not the fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid on your investment for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown reflect ongoing costs only, and do not include any transaction costs. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative costs of owning different funds. If transaction costs were included, total costs would be higher.

IXIS Cash Management Trust - Money Market Series (the "Fund") is the only series of IXIS Advisor Cash Management Trust (the "Trust"), a Massachusetts business trust registered under the Investment Company Act of 1940, as amended ("1940 Act"), as an open-end management investment company. The Declaration of Trust permits the Trustees to issue an unlimited number of shares of the Trust, without par value. The Fund seeks maximum current income consistent with preservation of capital and liquidity. The Fund offers Class A, Class B and Class C shares. The classes of the Fund enable shareholders of another IXIS Advisor Fund or Loomis Sayles Fund to invest in the Fund through an exchange of shares. The classes of the Fund are identical except for different exchange privileges. Shares of the Fund are sold without a front-end sales charge. Shares acquired by exchange of shares from another IXIS Advisor Fund may be subject to a contingent deferred sales charge if the shares exchanged were subject to a contingent deferred sales charge. For exchanges into the Fund, the holding period for determining the contingent deferred sales charge for Class B and Class C shares will stop and resume only when an exchange into an applicable Fund occurs. 2. Significant Accounting Policies. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of management estimates that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. a. Security Valuation. The Fund employs the amortized cost method of security valuation as set forth in Rule 2a-7 under the 1940 Act which, in the opinion of the Trustees of the Trust, represents the fair value of the particular security. The amortized cost of a security is determined by valuing it at original cost and thereafter assumes a constant accretion/amortization to maturity of any discount/premium. By using amortized cost valuation, the Fund seeks to maintain a constant net asset value of $1.00 per share despite minor shifts in the market value of its portfolio securities. b. Repurchase Agreements. The Fund, through its custodian, receives delivery of the underlying securities collateralizing repurchase agreements. It is the Fund's policy that the market value of the collateral be at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party arrangements whereby the collateral is held at the custodian bank in a segregated account for the benefit of the Fund and the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon the Fund's ability to dispose of the underlying securities. c. Security Transactions and Related Investment Income. Security transactions are accounted for on trade date and interest income is recorded on an accrual basis. Interest income is increased by the accretion of discount and decreased by the amortization of premium. In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. d. Federal Income Taxes. The Fund intends to meet the requirements of the Internal Revenue Code applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income. Accordingly, no provision for federal income tax has been made. e. Dividends and Distributions to Shareholders. Dividends and distributions are declared daily to shareholders of record at the time and are paid monthly. Net capital gain distributions, if any, will be made annually. The timing and characterization of certain income and capital gain distributions are determined in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent book and tax basis differences relating to shareholder distributions, net investment income, and net realized gains will result in reclassifications to the capital accounts. Distributions from net investment income and short-term capital gains are treated as ordinary income for tax purposes. During the year ended June 30, 2006, distributions of $9,950,897 were paid to shareholders from ordinary income on a tax basis. f. Other. The Fund invests primarily in a portfolio of money market instruments maturing in 397 days or less and whose ratings are generally within the two highest rating categories of a nationally recognized rating agency. The ability of the issuers of the securities held by the Fund to meet their obligations may be affected by foreign, economic, political and legal developments in the case of foreign banks, foreign branches, subsidiaries of U.S. banks, or domestic economic developments in a specific industry, state or region. g. Indemnifications. Under the Trust's organizational documents, its officers and Trustees are indemnified against certain liability arising out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote. h. New Accounting Pronouncements. Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainty in Income Taxes -- an Interpretation of FASB Statement 109 ("FIN 48") was issued and became effective for fiscal years beginning after December 15, 2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Subsequent thereto, the United States Securities and Exchange Commission ("SEC") indicated that it would not object if a fund first adopts FIN 48 on the last business day of the first required financial reporting period for fiscal years 13 NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2006 (Unaudited) beginning after December 15, 2006. Accordingly, Management is continuing to evaluate the impact the adoption of FIN 48 may have on the Fund's net assets and results of operations. In compliance with the recently issued SEC guidance, the impacts, if any, will be reflected in the Fund's annual financial statements as of June 30, 2007. In addition, in September, 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact, if any, the adoption of SFAS 157 will have on the Fund's financial statements. 3. Investment Transactions. For the six months ended December 31, 2006, purchases and proceeds from sales or maturities of short-term obligations (including securities purchased subject to repurchase agreements) were $3,440,925,743 and $3,454,884,044, respectively. 4. Management Fees and Other Transactions with Affiliates. a. Management Fees. IXIS Asset Management Advisors, L.P. ("IXIS Advisors") serves as the investment adviser to the Fund. Under the terms of the management agreement, the Fund pays a management fee at the following annual rates, calculated daily and payable monthly, based on the Fund's average daily net assets: Percentage of Average Daily Net Assets --------------------------------------------------------------------------- First Next Next Next Next Over $250 million $250 million $500 million $500 million $500 million $2 billion - - ------------ ------------ ------------ ------------ ------------ ---------- 0.35% 0.33% 0.31% 0.26% 0.25% 0.20% For the six months ended December 31, 2006, management fees for the Fund were $454,554 (0.35% of average daily net assets). IXIS Advisors has entered into a subadvisory agreement on behalf of the Fund with Reich & Tang Asset Management, LLC ("Reich & Tang"). Payments to IXIS Advisors are reduced in the amount of payments to Reich & Tang. IXIS Advisors and Reich & Tang are wholly owned subsidiaries of IXIS Asset Management US Group, L.P. ("IXIS US Group"), which is part of IXIS Asset Management Group, an International Asset Management Group based in Paris, France. Certain officers and directors of IXIS Advisors are also officers or Trustees of the Fund. b. Administrative Fees. IXIS Advisors provides certain administrative services to the Fund and subcontracts with State Street Bank and Trust Company ("State Street Bank") to serve as subadministrator. IXIS Advisors is a wholly owned subsidiary of IXIS US Group. Pursuant to an agreement among the Trust, IXIS Advisor Funds Trust I, IXIS Advisor Funds Trust II, IXIS Advisor Funds Trust III, IXIS Advisor Funds Trust IV ("IXIS Advisor Funds Trusts"), Loomis Sayles Funds I, Loomis Sayles Funds II ("Loomis Sayles Funds Trusts") and IXIS Advisors, each Fund pays IXIS Advisors monthly its pro rata portion of fees equal to an annual rate of 0.0675% of the first $5 billion of the average daily net assets of the IXIS Advisor Funds Trusts and Loomis Sayles Funds Trusts, 0.0625% of the next $5 billion, and 0.0500% of such assets in excess of $10 billion, subject to an annual aggregate minimum fee for the IXIS Advisor Funds Trusts and Loomis Sayles Funds Trusts of $5 million, which is reevaluated on an annual basis. For the six months ended December 31, 2006, the Fund paid $78,071 to IXIS Advisors for administrative fees. c. Distribution Agreement. IXIS Asset Management Distributors, L.P. ("IXIS Distributors"), a wholly owned subsidiary of IXIS US Group, is the Fund's distributor pursuant to a distribution agreement, although it receives no compensation from the Fund for such services. d. Trustees Fees and Expenses. The Fund does not pay any compensation directly to its officers or Trustees who are directors, officers or employees of IXIS Advisors, IXIS Distributors, IXIS US Group or their affiliates. The Chairperson of the Board receives a retainer fee at the annual rate of $200,000. The Chairperson does not receive any meeting attendance fees for Board of Trustees meetings or committee meetings that she attends. Each Independent Trustee (other than the Chairperson) receives, in the aggregate, a retainer fee at the annual rate of $55,000. Each Independent Trustee also receives a meeting attendance fee of $6,000 for each meeting of the Board of Trustees that he or she attends in person and $3,000 for each meeting of the Board of Trustees that he or she attends telephonically. In addition, each committee chairman receives an additional retainer fee at the annual rate of $10,000. Each Contract Review and Governance Committee member is compensated $4,000 for each Committee meeting that he or she attends in person and $2,000 for each meeting that he or she attends telephonically. Each Audit Committee member is compensated $5,000 for each Committee meeting that he or she attends in person and $2,500 for each meeting that he or she attends telephonically. These fees are allocated among the funds in the IXIS Advisor Funds Trusts and Loomis Sayles Funds Trusts based on a formula that takes into account, among other factors, the relative net assets of each fund. Trustees are reimbursed for travel expenses in connection with attendance at meetings. A deferred compensation plan (the "Plan") is available to the Trustees on a voluntary basis. Each participating Trustee will receive an amount equal to the value that such deferred compensation would have been had it been invested in a designated fund or certain other funds of the IXIS Advisor Funds Trusts and the Loomis Sayles Funds Trusts on the normal payment date. Deferred amounts remain in the funds until distributed in accordance with the Plan. 14 NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2006 (Unaudited) 5. Capital Shares.
