Flewharty, Reich & Tang Asset Management - -------------------------------------------------------------------------------- What You Should Know: The fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. 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 - -------------------------------------------------------------------------------- During the closing months of 2005, the interest rate climate was relatively unchanged from earlier in the year - short-term rates trended slowly higher, but remained at historically low levels. During the period, the Federal Reserve Board (the Fed) continued its series of gradual increases in interest rates, which raised yields on money market investments. For the six months ended December 31, 2005, IXIS Cash Management Trust -- Money Market Series maintained a constant price of $1.00 per share and provided a total return of 1.47% based on the net asset value of Class A shares and $0.0146 per share in reinvested dividends. The fund's seven-day yield as of the end of December was 3.44%. SHORT-TERM INTEREST RATES RISE AT MEASURED PACE Hurricane Katrina - one of the worst natural disasters in U.S. history - contributed to record high prices for gasoline, natural gas and oil, and to fears of a corresponding leap in inflation. The Fed responded to this and to other inflationary pressures during the period by continuing a program of raising short-term interest rates. Just prior to the start of the fund's fiscal year on July 1, 2005, the Fed announced a 0.25% increase in the Federal funds rate (the rate that banks charge each other for overnight loans), bringing the rate up to 3.25%. The Fed continued to raise rates in 0.25% increments at each of its four subsequent meetings in 2005: in August, September, November and December. The December interest rate move was the thirteenth consecutive quarter-point hike in rates since June 2004. By year-end, the Federal funds rate stood at 4.25%, its highest level in about four and a half years. ANTICIPATING MORE RATE HIKES TO COME, FUND REMAINS FLEXIBLE Our strategy throughout the period has been the same approach we outlined in recent reports. We worked to generate as much income as possible. Although money market rates remained low, they continued to rise, allowing the fund's income level to rise gradually. We maintained a relatively short average maturity throughout the period. Although longer-term securities generally offer higher yields than shorter-term issues, we felt it wasn't worth the risk of locking in current rates when we believed even higher rates might be ahead. As a result, we kept the fund's average maturity under 30 days, freeing up assets to invest in higher-yielding securities as they became available. At the start of the fund's fiscal year in July, its average maturity was 17 days. By the end of December, its average maturity was 19 days. FOCUS ON COMMERCIAL PAPER As has been the case for some time now, commercial paper composed the bulk of the fund's assets. These securities - issued by companies rather than the U.S. government - tend to offer higher yields than other types of money market instruments, with minimal additional risk, especially at the shorter end of the maturity spectrum. This has made commercial paper especially popular among money market investors in the current environment. With the economy apparently on a stable footing, we had relatively little concern about credit downgrades, which enabled us to focus on income. The fund maintained a minimal position in U.S. government agency securities. In addition, variable-rate demand instruments accounted for approximately a quarter of fund assets. Yields on these securities rise and fall with interest rates, so this strategy helps boost the fund's yield when rates are climbing. OUTLOOK FOR 2006: FLATTER RATES MAY LIE AHEAD With economic growth accelerating, inflation concerns increasing, and the unemployment rate dropping, we remain cautious. As most market observers had expected, the Fed extended its tightening program at its policy meeting on January 31, 2006. This brought the Federal funds rate to 4.50%-a relatively neutral rate. 1 IXIS CASH MANAGEMENT TRUST -- MONEY MARKET SERIES - -------------------------------------------------------------------------------- However, there is some risk that rates could climb even higher, at least temporarily, if the Fed decides it is necessary to keep inflation pressures in check. Recent comments made by Ben Bernanke, the newly elected Federal Reserve chairman, seem to support the prevailing view. Fed officials also recently revised the language of their closely watched policy statement, implying that they may be close to the end of their tightening cycle, while still leaving open the possibility of more aggressive rate hikes in the future. With this in mind, we plan to take a wait-and-see approach in the next several months. If we believe that the Fed is finished raising rates, we may begin to extend the fund's maturity to lock in higher yields. However, if the economy takes an unexpected turn, or inflation appears likely to pick up steam, the Fed may decide it has no other option than to increase rates aggressively. This would cause us to keep average maturity relatively short in an effort to maintain the flexibility we need in order to move quickly later in the cycle.

NOT FDIC INSURED MAY LOSE VALUE NO BANK GUARANTEE 3 UNDERSTANDING YOUR FUND'S 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 shows the actual account values and actual fund expenses you would have paid on a $1,000 investment in the Fund from July 1, 2005 through December 31, 2005. 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 the Period row as shown below for your Class. The second line in the table for each Class 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.

Organization. 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 (the "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 in the same classes 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, and to the extent that, the shares exchanged were subject to a contingent deferred sales charge. 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 Subadviser is responsible for determining that the value of the collateral is at all times at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party agreements 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. Distributions from net investment income and short-term capital gains are treated as ordinary income for tax purposes. At June 30, 2005, the Fund had, for federal income tax purposes, a capital loss carryforward of $539, which may be available to offset future realized gains, if any, to the extent provided by regulations and thus will reduce the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Such capital loss carryforward will expire on June 30, 2013. 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, or subsidiaries of U.S. banks, or domestic economic developments in a specific industry, state or region. g. Indemnifications. Under the Fund'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 Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote. 3. Investment Transactions. For the six months ended December 31, 2005, purchases and proceeds from sales or maturities of short-term obligations (including securities purchased subject to repurchase agreements) were $4,258,557,605 and $4,319,041,671, respectively. 13 NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2005 (unaudited) 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, 2005, management fees for the Fund were $538,071 (0.345% 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 the Subadviser. IXIS Advisors and Reich & Tang are wholly owned subsidiaries of IXIS Asset Management North America, L.P. ("IXIS North America"). Certain officers and directors of IXIS Advisors are also officers or Trustees of the Fund. b. Administrative Expense. 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. Pursuant to an agreement among IXIS Advisor Funds Trust I, IXIS Advisor Funds Trust II, IXIS Advisor Funds Trust III, IXIS Advisor Funds Trust IV, IXIS Advisor Cash Management Trust ("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. Prior to September 1, 2005, Investors Bank & Trust Company served as the subadministrator. For the six months ended December 31, 2005, the Fund paid $104,345 to IXIS Advisors for administrative expenses. c. Transfer Agent Fees. Prior to October 1, 2005, IXIS Asset Management Services Company ("IXIS Services") was the transfer and shareholder servicing agent for the Fund and subcontracted with Boston Financial Data Services ("Boston Financial") to serve as sub-transfer agent. The Fund, for its Class A, B and C shares, paid fees monthly to IXIS Services equal to an annual rate of $27.55 for each open account and $2.00 for each closed account, subject to a monthly minimum of $1,500 per class and an annual aggregate minimum fee of approximately $1 million. Effective October 1, 2005 Boston Financial became the transfer and shareholder servicing agent for the Fund under a new agreement with the Trust. Under this new agreement, the Fund pays fees to Boston Financial pursuant to a different schedule. For the period from July 1 to September 30, 2005, the Fund paid $258,057 to IXIS Services as compensation for its services as transfer agent. IXIS Services (prior to October 1, 2005), Boston Financial and other firms are also reimbursed by the Fund for out-of-pocket expenses. In addition, pursuant to other servicing agreements, the Fund paid service fees to other firms that provide similar services for their own shareholder accounts. d. Distribution Agreement. IXIS Asset Management Distributors, L.P. ("IXIS Distributors"), a wholly-owned subsidiary of IXIS North America, is the Fund's distributor pursuant to a distribution agreement, although it receives no compensation from the Fund for such services. e. 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 North America 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 committee member receives $4,000 for each committee meeting that he or she attends in person and $2,000 for each committee 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. Prior to November 18, 2005, the Trust had co-chairmen of the Board. Prior to October 1, 2005, each independent Trustee received, in the aggregate, a retainer fee at the annual rate of $50,000 and meeting attendance fees of $5,000 for each meeting of the Board of Trustees that he or she attended.

Each committee member received $3,750 for each committee meeting that he or she attended. 14 NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2005 (unaudited) Effective January 1, 2006, each Audit Committee member will be compensated $5,000 for each Audit Committee meeting that he or she attends in person and $2,500 for each meeting he or she attends telephonically. 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. Additionally, the Board of Trustees has approved the use of Fund assets to pay its portion of the annual salary for 2005 of an employee of IXIS Advisors who supports the Fund's Chief Compliance Officer. For the six months ended December 31, 2005, the Fund's portion of such expense was approximately $1,200. 5. Capital Shares.
