Although rates are still historically low, money market yields have improved. Throughout the six months ended December 31, 2004, CDC Nvest Cash Management Trust -- Money Market Series maintained a constant value of $1.00 per share. The six-month return on Class A shares of the fund was 0.37% based on $0.0037 per share in reinvested dividends. The fund's annualized seven-day SEC yield at the end of December 2004 was 1.25%. Short-term Interest Rates Rose Five Times in Increments Of 0.25% The fund's fiscal year began on July 1, 2004, shortly after the Federal Reserve Board announced the first in a series of 0.25% increases in the federal funds rate - the only rate the Fed directly controls. This was the first increase in more than four years. Faced with improving economic data, and in an effort to keep inflation in check, the Fed followed with four more increases of 0.25% each, bringing the federal funds rate to 2.25% by the end of December. The Fed's goal in adjusting interest rates is to keep the economy on an even keel, cutting rates to stimulate growth during recessions, and raising them to head off inflation when the economy appears in danger of growing too quickly. In 2004, wage and retail price inflation was almost nonexistent, and despite the rising price of oil, the cost of living advanced relatively slowly. However, there was some concern that interest rates had been so low for so long, they might provide too much stimulus and risk overheating the economy. The current benign outlook allowed the Fed to raise interest rates gradually, avoiding more aggressive credit tightening that could derail the expansion. Fund Maintains Flexible Structure as Rates Rise Our strategy throughout the period remained consistent. With money market rates low but gradually rising, we strove to generate as much income as possible while maintaining sufficient flexibility to capture higher rates as they became available. Although longer-term securities generally offer a yield advantage over shorter-term issues, we felt it wasn't worth the risk of locking in the highest rates available today when we believed tomorrow's rates were likely to be even higher. As a result, we kept the fund's average maturity on the shorter side, freeing up assets to take advantage of higher-yielding issues as they became available. At the start of your fund's fiscal year in July, its average maturity was 35 days. As of December 31, 2004, the average maturity was 20 days. Although maturities shift every day as we buy and sell securities or as they mature, we tended to keep maturities short to make assets available for reinvestment at higher rates. Seeking Higher Yield, Fund Focuses On Commercial Paper Because we seek high current income from money market investments, commercial paper typically constitutes the majority of the fund's assets. These money market securities - issued by companies rather than the U.S. government - typically offer higher yields than Treasuries and other, similar instruments, with minimal additional risk, especially on the short end of the maturity spectrum. However, during periods of economic uncertainty, the fund tends to keep a greater portion of assets in U.S. government and agency securities for safety reasons. Given the current improvement in the economy and reduced concern about credit downgrades, we have focused the fund's assets on commercial paper. We also maintained a portion of assets in variable-rate demand instruments because the rate they pay rises and falls with changing interest rates. Outlook is for Moderate Growth and Slowly Rising Rates in 2005 Although we anticipate moderate economic growth in the year ahead, risks still abound. Energy prices are high, the dollar is weak, and the budget and trade deficits are huge. Most observers expect the Fed to continue to raise rates at least through the first half of 2005. Fed officials themselves have underscored the likelihood of further rate hikes. In a statement released with December's interest rate decision, the Fed depicted an economy growing at a moderate pace with a low risk of inflation. However, the Fed also said that interest rates are still so low that they are potentially inflationary, adding that they would raise rates at a "measured" pace. This has been widely interpreted to signal a series of quarter-point interest rate increases. Consequently, we are taking a wait-and-see approach, monitoring economic statistics as they become available and watching the Fed's actions closely. In the meantime, shareholders are earning more generous yields than they have in recent periods, and we believe the fund is positioned to capture higher rates as they become available. 2 - -------------------------------------------------------------------------------- Understanding Your Fund's Expenses - -------------------------------------------------------------------------------- As a mutual fund shareholder, you incur different costs: transaction costs, including sales charges (loads) on purchases, and certain exchange fees, and ongoing costs, including management fees, sales and distribution fees (12b-1 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 shows the actual account values and actual fund expenses you would have paid on a $1,000 investment in the fund from July 1, 2004 through December 31, 2004. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual fund returns and expenses. 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 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. CDC Nvest Cash Management Trust - Money Market Series (the "Trust") is organized as a Massachusetts business trust. The Trust is 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. The Trust offers Class A, Class B and Class C shares. The Trust seeks maximum current income consistent with preservation of capital and liquidity. Shares of the Trust are sold without a front end sales charge. Shares acquired by exchange of shares of another CDC Nvest or Loomis Sayles Fund may be subject to a contingent deferred sales charge. 2. Significant Accounting Policies. The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements. The Trust'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 Trust 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. b. Repurchase Agreements. The Trust, through its custodian, receives delivery of the underlying securities collateralizing repurchase agreements. It is the Trust'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. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon the Trust'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 Trust 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. Distributions from net investment income and short-term capital gains are treated as ordinary income for tax purposes. e. Dividends and Distributions to Shareholders. Dividends and distributions are declared daily to shareholders of record at the time and are paid monthly. Long-term gain distributions, if any, will be made annually. The timing and characterization of certain income and capital gains distributions are determined in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences are primarily due to deferred Trustee fees. f. Other. The Trust 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 Trust 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. 3. Investment Transactions. For the six months ended December 31, 2004, purchases and sales or maturities of short-term obligations (including securities purchased subject to repurchase agreements) were $4,457,979,312 and $4,514,165,511, respectively. 4. Management Fees and Other Transactions with Affiliates. a. Management Fees. IXIS Asset Management Advisors, L.P. ("IXIS Advisors"), formerly CDC IXIS Asset Management Advisers, L.P., is the investment adviser to the Trust. Under the terms of the management agreement, the Trust pays a management fee at the following annual rates, calculated daily and payable monthly, based on the Trust's average daily net assets: Percentage of Average Daily Net Assets - ---------------------------------------------------------------------- First Next Next Next Over $500 million $500 million $500 million $500 million $2 billion - ------------ ------------ ------------ ------------ ---------- 0.400% 0.375% 0.325% 0.275% 0.225% 11 - -------------------------------------------------------------------------------- Notes to Financial Statements (continued) - -------------------------------------------------------------------------------- For the Six Months Ended December 31, 2004 (unaudited) For the six months ended December 31, 2004, management fees for the Trust were $705,568 (0.400% of average daily net assets). IXIS Advisors has entered into a subadvisory agreement on behalf of the Trust 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"), formerly CDC IXIS Asset Management North America, L.P. Certain officers and directors of IXIS Advisors are also officers or Trustees of the Trust. b. Accounting and Administrative Expense. During the period, IXIS Asset Management Services Company ("IXIS Services"), formerly CDC IXIS Asset Management Services, Inc., a wholly owned subsidiary of IXIS North America, performed certain accounting and administrative services for the Trust and subcontracted with Investors Bank & Trust Company ("IBT") to serve as subadministrator. Pursuant to the agreement between the Trust, CDC Nvest Funds Trust I, CDC Nvest Funds Trust II, CDC Nvest Funds Trust III, CDC Nvest Companies Trust I ("CDC Nvest Funds Trusts"), Loomis Sayles Funds I, and Loomis Sayles Funds II ("Loomis Sayles Funds Trusts") (collectively, the "Trusts"), and IXIS Services, the Trust paid IXIS Services its pro rata portion of a group fee for these services representing the higher amount based on the following calculations: (1) Percentage of Eligible Average Daily Net Assets First Next Over $5 billion $5 billion $10 billion - ---------- ---------- ----------- 0.0675% 0.0625% 0.0500% or (2) The Trust's pro rata portion, allocated based on the combined assets of the Trusts, of the annual aggregate minimum fee of $5 million.

IXIS Services is the transfer and shareholder servicing agent for the Trust and has subcontracted with Boston Financial Data Services ("BFDS") to serve as subtransfer agent. The Trust pays IXIS Services service fees for servicing shareholder accounts. During the period, Classes A, B and C paid service fees monthly representing the higher amount based on the following calculations: (1) An annual fee determined by applying an annual fee rate (see schedule below) to the eligible average daily net assets. Eligible assets are the average daily net assets of Class A, Class B and Class C accounts in the Trust. First Next Over $650 million $5 billion $5.65 billion - ------------ ---------- ------------- 0.239% 0.200% 0.195% Each Class of shares is subject to a monthly class minimum of $1,500. or (2) An annual minimum fee of $1.4 million.

Additionally, the Trust reimbursed IXIS Services, BFDS and other firms for out-of-pocket expenses. Effective January 1, 2005, the Fund, for its Class A, B, and C shares, will pay fees to IXIS Services representing the greater of: (1) An aggregate annual minimum fee of approximately $1 million; or (2) An aggregate annual fee determined by applying an annual account based fee of $27.55 for each open account and $2.00 for each closed account. Each Class of shares is subject to a monthly class minimum of $1,500. In addition, pursuant to other servicing agreements, the Trust pays service fees to other firms that provide similar services for their own shareholder accounts. 12 - -------------------------------------------------------------------------------- Notes to Financial Statements (continued) - -------------------------------------------------------------------------------- For the Six Months Ended December 31, 2004 (unaudited) d. Trustees Fees and Expenses. The Trust does not pay any compensation directly to its officers or Trustees who are directors, officers or employees of IXIS Advisors, IXIS Asset Management Distributors, L.P., IXIS North America, IXIS Services or their affiliates. Each Trustee who is an independent Trustee of the CDC Nvest Funds Trusts and the Loomis Sayles Funds Trusts receives 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 attended. Each committee chairman receives an additional retainer fee at the annual rate of $7,000. Each committee member receives a meeting attendance fee of $3,750 per committee meeting attended. The Co-Chairmen of the Board each receive an additional annual retainer of $25,000. These fees are allocated to the various series of the CDC Nvest Funds Trusts and the 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 CDC Nvest 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. e. Publishing Services. IXIS Services performs certain desktop publishing services for the Trust. Fees for these services are presented in the Statement of Operations as shareholder reporting.
