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

Economic and market turbulence – especially during the first part of the year – defined the 12 months ended June 30, 2009. The full impact of the subprime mortgage crisis and years of questionable residential mortgage lending practices came to a head as housing prices continued to fall. Home foreclosures rose, investment banks reported staggering losses, and the unemployment rate skyrocketed.

In an effort to restore order to the financial markets, the U.S. government and the Federal Reserve Board took unprecedented actions. President Obama sent a spending/stimulus plan totaling nearly $1 trillion through Congress. At the same time, the Fed slashed the federal funds rate to between 0.00% and 0.25% – an all-time low – and the U.S. Treasury Department unveiled a series of programs designed to remove toxic assets from bank balance sheets and get credit flowing freely again. (The federal funds rate directly influences yields on money market securities.)

For the fiscal year ended June 30, 2009, Natixis Cash Management Trust – Money Market Series maintained a constant value 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 SEC yield at the end of the period was 0.19%.

U.S. TREASURY GUARANTEES MONEY MARKET FUNDS

As negative economic news mounted, investors flocked to money market mutual funds in pursuit of safety. However, the industry also suffered a crisis of confidence triggered by one fund “breaking the buck,” returning investors less than they paid in.

In response, the U.S. Treasury Department established a temporary guarantee program for the U.S. money market fund industry. The program provides coverage to shareholders of any participating money market mutual fund for amounts they held in that fund as of the close of business on September 18, 2008. The fund’s Board of Trustees determined that, considering the cost of participating in the program and the potential benefits to the fund and its shareholders, the fund would participate in the program and subsequently extended its participation through September 18, 2009. (See Note 8 to the Financial Statements.)

The Fed also instituted two commercial paper programs that allowed money market funds to sell money market securities to the government, if necessary, in order to recoup costs. These initiatives helped restore order to the market.

MANAGER ADOPTS CONSERVATIVE APPROACH

Against this backdrop, we adopted a conservative approach, sacrificing some yield to ensure safety in the portfolio by focusing on top quality, while maintaining liquidity in order to meet shareholder demands.

We gradually reduced the fund’s average maturity from 44 days at the start of the fund’s fiscal year to 32 days at mid year on December 31, 2008. The fund’s maturity was 33 days as of June 30, 2009. Typically in a falling interest rate environment we would extend maturity to lock in higher returns. However, because of the severity of the financial crisis we kept maturity on the short side in an effort to ensure that adequate cash was on hand to satisfy shareholder needs.

COMMERCIAL PAPER AND CDS WERE MAJOR HOLDINGS

Commercial paper, which is issued by companies rather than the U.S. government or its agencies, accounted for a significant portion of the portfolio. These securities are not backed or insured by the U.S. government, but they tend to offer higher yields with relatively little additional risk, especially on the shorter end of the maturity spectrum.

Early in the period, commercial paper comprised 53.3% of fund assets. However, as market volatility increased we reduced our weighting in these securities and shifted assets to certifi-

cates of deposit (CDs). As of December 31, 2008, the fund’s position in commercial paper had fallen to 24.4%. As the market began to stabilize early in 2009, we initiated a program of gradually redirecting assets to commercial paper for added liquidity, flexibility and higher returns. As of June 30, 2009, commercial paper accounted for 44.6% of net assets.

Reflecting our emphasis on safety and liquidity, CDs from leading institutions accounted for a significant portion of fund assets. We focused on multi-national banks and major domestic banks to capture yield, while avoiding smaller, regional banks that were not covered by the Treasury programs. Just over 27% of net assets was invested in CDs as of June 30, 2008. This position rose to 55.7% at December 31, 2008, and then fell to 44.3% as of June 30, 2009.

Our position in variable-rate demand instruments and floating-rate notes increased slightly during the period, from 11.4% of fund assets at the start of the fund’s fiscal year to 11.8% as of December 31, 2008, before dropping to 5.9% as of June 30, 2009. Yields on variable- and floating-rate securities rise and fall with day-to-day fluctuations in interest rates caused by market sentiment. If short-term rates decline, so does the yield on these securities. As they matured, we redirected assets to fixed-rate money market securities to lock in yields.

We added to the fund’s holdings in time deposits in the first half and had trimmed the position by June 30, 2009. We avoided U.S. government and agency securities altogether during the fund’s fiscal year.

FOSTERING ECONOMIC GROWTH IS FED’S KEY CONCERN

At its most recent meeting in June, the Fed announced plans to maintain the target range for the federal funds rate at 0.00% to 0.25% for “an extended period.” The Fed wants to help get credit flowing by keeping rates low for business loans, mortgages, and other borrowing needs. Fostering economic growth without triggering inflation is the Central Bank’s primary concern.

Our approach in the months ahead will be to continue our recent strategies. We plan to keep a watchful eye on economic data and closely monitor the Fed’s actions. We will also continue our defensive approach, focusing on liquidity to meet shareholder needs and seeking opportunities to selectively extend average maturity among larger, well-established issuers to capture additional yield without sacrificing safety.

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 January 1, 2009 through June 30, 2009. 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.

BOARD APPROVAL OF THE EXISTING ADVISORY AND SUB-ADVISORY AGREEMENTS

The Board of Trustees, including the Independent Trustees, considers matters bearing on the Fund’s advisory and sub-advisory agreements (collectively, the “Agreements”) at most of its meetings throughout the year. Each year, usually in the spring, the Contract Review and Governance Committee of the Board meets to review the Agreements to determine whether to recommend that the full Board approve the continuation of the Agreements, typically for an additional one-year period. After the Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements.

In connection with these meetings, the Trustees receive materials that the Fund’s investment adviser and subadviser (collectively, the “Advisers”) believe to be reasonably necessary for the Trustees to evaluate the Agreements. These materials generally include, among other items, (i) information on the investment performance of the Fund and the performance of peer groups of funds and the Fund’s performance benchmarks, (ii) information on the Fund’s advisory and sub-advisory fees and other expenses, including information comparing the Fund’s expenses to those of peer groups of funds and information about any applicable expense caps and fee “breakpoints,” (iii) sales and redemption data in respect of the Fund, (iv) information about the profitability of the Agreements to the Fund’s Advisers and (v) information obtained through the completion of a questionnaire by the Advisers (the Trustees are consulted as to the information requested through that questionnaire). The Board of Trustees, including the Independent Trustees, also consider other matters such as (i) each Adviser’s financial results and financial condition, (ii) the Fund’s investment objective and strategies and the size, education and experience of the Advisers’ respective investment staffs and their use of technology, external research and trading cost measurement tools, (iii) arrangements in respect of the distribution of the Fund’s shares and the related costs, (iv) the procedures employed to determine the value of the Fund’s assets, (v) the allocation of the Fund’s brokerage, if any, including, if applicable, allocations to brokers affiliated with the Advisers and the use of “soft” commission dollars to pay Fund expenses and to pay for research and other similar services, (vi) the resources devoted to, and the record of compliance with, the Fund’s investment policies and restrictions, policies on personal securities transactions and other compliance policies, (vii) information about amounts invested by the Fund’s portfolio managers in the Fund or in similar accounts that they manage and (viii) the general economic outlook with particular emphasis on the mutual fund industry. Throughout the process, the Trustees are afforded the opportunity to ask questions of and request additional materials from the Advisers.

In addition to the materials requested by the Trustees in connection with their annual consideration of the continuation of the Agreements, the Trustees receive materials in advance of each regular quarterly meeting of the Board of Trustees that provide detailed information about the Fund’s investment performance and the fees charged to the Fund for advisory and other services. This information generally includes, among other things, an internal performance rating for the Fund based on agreed-upon criteria, graphs showing performance and fee differentials against the Fund’s peer group of funds, performance ratings provided by a third-party, total return information for various periods, and third-party performance rankings for various periods comparing the Fund against its peer group. The portfolio management team for the Fund or other representatives of the Advisers make periodic presentations to the Contract Review and Governance Committee and/or the full Board of Trustees, and if the Fund is identified as presenting possible performance concerns it may be subject to more frequent board presentations and reviews.

The Board of Trustees most recently approved the continuation of the Agreements at their meeting held in June, 2009. The Agreements were continued for a one-year period. In considering whether to approve the continuation of the Agreements, the Board of Trustees, including the Independent Trustees, did not identify any single factor as determinative. Individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. Matters considered by the Trustees, including the Independent Trustees, in connection with their approval of the Agreements included the factors listed below.

The nature, extent and quality of the services provided to the Fund under the Agreements. The Trustees considered the nature, extent and quality of the services provided by the Advisers and their affiliates to the Fund and the resources dedicated to the Fund by the Advisers and their affiliates. They considered the need for the Advisers to offer competitive compensation in order to attract and retain capable personnel.

The Trustees considered not only the advisory services provided by the Advisers to the Fund, but also the monitoring and oversight services provided by Natixis Advisors. They also considered the administrative services provided by Natixis Advisors and its affiliates to the Fund.

5

The Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds that offers shareholders the right to exchange shares of one type of fund for shares of another type of fund, and provides a variety of fund and shareholder services.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the renewal of the Agreements.

Investment performance of the Fund and the Advisers. As noted above, the Trustees received information about the performance of the Fund over various time periods, including information which compared the performance of the Fund to the performance of a peer group of funds. In addition, the Trustees also reviewed data prepared by an independent third party which analyzed the performance of the Fund using a variety of performance metrics, including metrics which also measured the performance of the Fund on a risk adjusted basis.

With respect to the Fund, the Board concluded that the Fund’s performance or other relevant factors supported the renewal of the Agreements.

The Trustees also considered each Adviser’s performance and reputation generally, the performance as a fund family generally (as noted by certain financial publications), and the historical responsiveness of the Advisers to Trustee concerns about performance and the willingness of the Advisers to take steps intended to improve performance.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of the Fund and the Advisers supported the renewal of the Agreements.

The costs of the services to be provided and profits to be realized by the Advisers and their affiliates from their respective relationships with the Fund. The Trustees considered the fees charged to the Fund for advisory and sub-advisory services as well as the total expense level of the Fund. This information included comparisons (provided both by management and also by an independent third party) of the Fund’s advisory fees and total expense levels to those of their peer groups and information about the advisory fees charged by the Advisers to comparable accounts. In considering the fees charged to comparable accounts, the Trustees considered, among other things, management’s representations about the differences between managing mutual funds as compared to other types of accounts, including the additional resources required to effectively manage and the greater regulatory costs associated with the management of mutual fund assets. In evaluating the Fund’s advisory and sub-advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of the Fund. The Trustees considered that over the past several years, management had made recommendations regarding reductions in advisory fee rates.

The Trustees also considered the compensation directly or indirectly received by the Advisers and their affiliates from their relationships with the Fund. The Trustees reviewed information provided by management as to the profitability of the Advisers’ and their affiliates’ relationships with the Fund, and information about the allocation of expenses used to calculate profitability. They also reviewed information provided by management about the effect of distribution costs and changes in asset levels on Adviser profitability, including information regarding resources spent on distribution activities. When reviewing profitability, the Trustees also considered information about court cases in which adviser profitability was an issue, the performance of the Fund, the expense levels of the Fund, and whether the Advisers had implemented breakpoints and/or expense caps. The Trustees also noted that the Fund’s net expense ratio was above the median of its peer group of funds and management’s representation that the difference was in large part due to higher transfer agency costs.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to the Fund were fair and reasonable, and that the costs of these services generally and the related profitability of the Advisers and their affiliates in respect of their relationships with the Fund supported the renewal of the Agreements.

Economies of Scale. The Trustees considered the existence of any economies of scale in the provision of services by the Advisers and whether those economies are shared with the Fund through breakpoints in their investment advisory fees or other means, such as expense waivers or caps. The Trustees also took note of the costs of the services provided (both on an absolute and a relative basis) and the profitability to the Advisers and their affiliates of their relationships with the Fund, as discussed above.

6

After reviewing these and related factors, the Trustees considered, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the Fund supported the renewal of the Agreements.

The Trustees also considered other factors, which included but were not limited to the following:

· the effect of recent market and economic turmoil on the performance, asset levels and expense ratios of the Fund. The Trustees further noted that the Fund had participated in the U.S. Treasury Department’s temporary guarantee program for the U.S. money market fund industry and that the cost of the premium for participation in the program was borne by the Fund.

· whether the Fund has operated in accordance with its investment objective and the Fund’s record of compliance with its investment restrictions, and the compliance programs of the Fund and the Advisers. They also considered the compliance-related resources the Advisers and their affiliates were providing to the Fund.

· the nature, quality, cost and extent of administrative and shareholder services performed by the Advisers and their affiliates, both under the Agreements and under separate agreements covering administrative services.

· so-called “fallout benefits” to the Advisers, such as the engagement of affiliates of the Advisers to provide distribution, administrative and brokerage services to the Fund. The Trustees also considered the fact that Natixis Advisors’ parent company benefits from the retention of affiliated Advisers. The Trustees considered the possible conflicts of interest associated with these fallout and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor such possible conflicts of interest.

· the Trustees’ review and discussion of the Fund’s advisory arrangements in prior years, and management’s record of responding to Trustee concerns raised during the year and in prior years.

Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel, the Trustees, including the Independent Trustees, concluded that each of the existing Agreements should be continued through June 30, 2010.

NOTES TO FINANCIAL STATEMENTS

June 30, 2009

1.  Organization.  Natixis Cash Management Trust – Money Market Series (the “Fund”) is the only series of Natixis 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 and Class C shares. Effective October 12, 2007, Class B shares are no longer offered. Existing Class B shareholders may continue to reinvest dividends into Class B shares and exchange their Class B shares for Class B shares of other Natixis Funds subject to existing exchange privileges as described in the Prospectus. The classes of the Fund enable shareholders of another Natixis 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 Natixis Fund or Loomis Sayles Fund may be subject to a contingent deferred sales charge (“CDSC”) if the shares exchanged were subject to a CDSC. For exchanges into the Fund, the holding period for determining the CDSC for Class B and Class C shares will be suspended and resume only when an exchange into an applicable Fund occurs.

Expenses of the Fund are borne pro rata by the holders of each class of shares, except that each class bears expenses unique to that class. Shares of each class would receive their pro rata share of the net assets of the Fund if the Fund were liquidated. The Trustees approve separate dividends from net investment income on each class of shares.

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. Management has evaluated the events and transactions that have occurred through August 26, 2009, the date the financial statements were issued, and noted no items requiring recognition in the financial statements or additional disclosure in the Notes to Financial Statements.

a.  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.  It is the Fund’s policy that the market value of the collateral for repurchase agreements be at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party arrangements whereby the collateral is held in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty including possible delays or restrictions upon a 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. Management has performed an analysis of the Fund’s tax positions for the open tax years as of June 30, 2009 and has concluded that no provisions for income tax are required. The Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next twelve months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Fund. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

e.  Dividends and Distributions to Shareholders.  Dividends and distributions, if any, 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 years ended June 30, 2009 and June 30, 2008 distributions of $4,013,916 and $9,210,804 were paid to shareholders from ordinary income on a tax basis.

At June 30, 2009, the Fund had undistributed ordinary income on a tax basis of $247,463. The difference between the components of distributable earnings on a tax basis and the amounts reported in the Statement of Assets and Liabilities are primarily due to deferred Trustees’ fees and dividends payable.

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 non-U.S. banks, non-U.S. branches, or 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 liabilities 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.  Fair Value Measurements.  The Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157 (“FAS 157”), Fair Value Measurements, effective July 1, 2008. FAS 157 establishes a hierarchy for net asset value determination purposes in which various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in the three broad levels listed below:

• Level 1 — quoted prices in active markets for identical investments;

• Level 2 — prices determined using other significant observable inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar investments, interest rates, credit risk, etc.);

• Level 3 — prices determined using significant unobservable inputs for situations where quoted prices or observable inputs are unavailable such as when there is little or no market activity for an investment (unobservable inputs reflect the Fund’s own assumptions in determining the fair value of investments and would be based on the best information available).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used to value the Fund’s investments as of June 30, 2009:

Valuation Inputs	Investments in Securities
Level 1 — Quoted Prices	$	—
Level 2 — Other Significant Observable Inputs(a)		255,667,849
Level 3 — Significant Unobservable Inputs		—
Total	$	255,667,849

(a) Major categories of the fund’s investments are included in the Portfolio of Investments.

4.  Investment Transactions.  For the year ended June 30, 2009, purchases and proceeds from sales or maturities of short-term obligations (including securities purchased subject to repurchase agreements) were $ 5,443,587,008 and $ 5,424,954,542, respectively.

5.  Management Fees and Other Transactions with Affiliates.

a.  Management Fees.  Natixis Asset Management Advisors, L.P. (“Natixis 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 $250 million	Next $250 million	Next $500 million	Next $500 million	Next $500 million	Over $2 billion
0.35%	0.33%	0.31%	0.26%	0.25%	0.20%

Natixis Advisors has entered into a subadvisory agreement on behalf of the Fund with Reich & Tang Asset Management, LLC (“Reich & Tang”). Payments to Natixis Advisors are reduced by the amount of payments to Reich & Tang. Natixis Advisors and Reich & Tang are wholly-owned subsidiaries of Natixis Global Asset Management, L.P. (“Natixis US”), which is part of Natixis Global Asset Management, an international asset management group based in Paris, France. Certain officers and directors of Natixis Advisors are also officers or Trustees of the Fund.

Natixis Advisors has given a binding undertaking to the Fund to reduce management fees and/or reimburse certain expenses associated with the Fund to limit its operating expenses, exclusive of acquired fund fees and expenses, brokerage expenses, interest expense, taxes and extraordinary expenses. This undertaking is in effect until August 31, 2010 and will be re-evaluated on an annual basis. The expense limits as a percentage of average daily net assets under the expense limitation agreement are 0.65% for Class A, Class B and Class C shares of the Fund.

16

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2009

For the year ended June 30, 2009, the management fees and reductions of management fees for the Fund were as follows:

Gross Management Fee	Reduction of Management Fee		Net Management Fee		Percentage of Average Daily Net Assets
					Gross	Net
$954,023	$	—	$	954,023	0.35%	0.35%

Natixis Advisors shall be permitted to recover expenses it has borne under the expense limitation agreement (whether through reduction of its management fee or otherwise) on a class by class basis in later periods to the extent the expenses of a class fall below a class’ expense limit, provided, however, that a class is not obligated to pay such reduced fees/expenses more than one year after the end of the fiscal year in which the fee/expense was reduced. There are no amounts subject to possible recovery under the expense limitation agreements at June 30, 2009.

Natixis Advisors has temporarily agreed to waive its management fee to the extent necessary to maintain a minimum yield to shareholders. This agreement is voluntary and may be terminated at any time. Natixis Advisors did not waive any fees under this agreement during the fiscal year ended June 30, 2009.

b.  Administrative Fees.  Natixis Advisors provides certain administrative services for the Fund and subcontracts with State Street Bank to serve as sub-administrator. Pursuant to an agreement among the Trust, Natixis Funds Trust I, Natixis Funds Trust II, Natixis Funds Trust III, Natixis Funds Trust IV, Gateway Trust (“Natixis Funds Trusts”), Loomis Sayles Funds I, Loomis Sayles Funds II (“Loomis Sayles Funds Trusts”), Hansberger International Series and Natixis Advisors, the Fund pays Natixis Advisors monthly its pro rata portion of fees equal to an annual rate of 0.0575% of the first $15 billion of the average daily net assets of the Natixis Funds Trusts, Loomis Sayles Funds Trusts and the Hansberger International Series, 0.0500% of the next $15 billion, 0.0425% of the next $30 billion and 0.0375% of such assets in excess of $60 billion, subject to an annual aggregate minimum fee for the Natixis Funds Trusts, Loomis Sayles Funds Trusts and the Hansberger International Series of $10 million, which is reevaluated on an annual basis. New funds are subject to a fee for the first twelve months of operations of $75,000 plus $12,500 per class and an additional $75,000 if managed by multiple subadvisors.

For the year ended June 30, 2009, the Fund paid $135,581 to Natixis Advisors for administrative fees.

c.  Distribution Agreement.  Natixis Distributors, L.P. (“Natixis Distributors”), a wholly-owned subsidiary of Natixis US, is the Fund’s distributor pursuant to a distribution agreement, although it receives no compensation from the Fund for such services.

d.  Sub-Transfer Agent Fees.  Natixis Distributors has entered into agreements with financial intermediaries to provide certain recordkeeping, processing, shareholder communications and other services to customers of the intermediaries and has agreed to compensate the intermediaries for providing those services. Certain services would be provided by the Fund if the shares of those customers were registered directly with the Fund’s transfer agent. Accordingly, the Fund agreed to pay a portion of the intermediary fees attributable to shares of the Fund held by the intermediaries (which generally are a percentage of the value of shares held) not exceeding what the Fund would have paid its transfer agent had each customer’s shares been registered directly with the transfer agent instead of held through the intermediaries. Natixis Distributors pays the remainder of the fees. Listed below are the fees incurred by the Fund which are included in the transfer agent fees and expenses in the Statement of Operations.

Sub-Transfer Agent Fees
Class A	Class B		Class C
$7,941	$	615	$	736

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 Natixis Advisors, Natixis Distributors, Natixis US, 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 $65,000. Each Independent Trustee also receives a meeting attendance fee of $7,500 for each meeting of the Board of Trustees that he or she attends in person and $3,750 for each meeting of the Board of Trustees that he or she attends telephonically. In addition, each committee chair receives an additional retainer fee at the annual rate of $10,000. Each Contract Review and Governance 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. Each Audit Committee member is compensated $6,250 for each Committee meeting that he or she attends in person and $3,125 for each meeting that he or she attends telephonically. These fees are allocated among the funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts and the Hansberger International Series 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. Deferred amounts remain in the Fund until distributed in accordance with the provisions of the Plan. The value of a participating Trustee’s deferral account is based on theoretical investments of deferred amounts, on the normal payment dates, in certain funds

17

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2009

of the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Hansberger International Series as designated by the participating Trustees. Changes in the value of participants’ deferral accounts are allocated pro rata among the funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts, and Hansberger International Series, and are reflected as Trustees’ fees and expenses in the Statement of Operations. The portion of the accrued obligations allocated to the Fund under the Plan is reflected as Deferred Trustees’ fees in the Statement of Assets and Liabilities.

For the year ended June 30, 2009, net depreciation of $67,333 in the value of participants’ deferral accounts has been included as a reduction of miscellaneous expense on the Statement of Operations.

f.  Minimum Balance Fees.  An annual minimum balance fee of $20 may apply to accounts that fall below the minimum amount required to establish an account, in order to reduce the impact of small accounts on transfer agent fees. These fees are reflected as expense offsets on the Statement of Operations.

6.  Line of Credit.  The Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and the Hansberger International Series, participates in a $200,000,000 unsecured committed line of credit provided by State Street Bank, with an individual limit of $125,000,000 for each fund that participates in the line of credit. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the greater of the Federal Funds rate or overnight LIBOR rate plus 0.75%. In addition, a commitment fee of 0.125% per annum, payable at the end of each calendar quarter, is accrued and apportioned among the participating funds based on their average daily unused portion of the line of credit.

Prior to March 11, 2009, the Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and the Hansberger International Series, participated in a $200,000,000 unsecured committed line of credit provided by State Street Bank, with an individual limit of $125,000,000 for each fund that participated in the line of credit. Interest was charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.09% per annum, payable at the end of each calendar quarter, was accrued and apportioned among the participating funds based on their average daily unused portion of the line of credit.

For the year ended June 30, 2009, the Fund had no borrowings under these agreements.

7.  Capital Shares.  The Fund may issue an unlimited number of shares of beneficial interest, without par value. Transactions in capital shares at a constant net asset value of $1.00 per share were as follows:

8.  U.S. Treasury Temporary Guarantee Program for Money Market Funds.  During the year ended June 30, 2009, the Fund paid a percentage of its net asset value as of September 19, 2008 to participate in the Temporary Guarantee Program for Money Market Funds (the “Program”) offered by the United States Department of the Treasury (“U.S. Treasury”). The Fund paid $111,225 to participate in the Program through September 18, 2009. As of June 30, 2009, the Fund expensed $87,560, which is reflected in the Statement of Operations under the caption “Miscellaneous”. This expense is not subject to the binding undertaking to limit operating expenses as described in Note 5.

Subject to certain conditions and limitations, in the event that the per share value of the Fund falls below $0.995 and the Fund liquidates its holdings, the Program guarantees shareholders of the Fund $1.00 per share for the lesser of either the number of shares the investor held in the Fund on September 19, 2008 or the number of shares the

investor held on the date the net asset value fell below $0.995. The Program applies only to shareholders of record on September 19, 2008 who maintain an account with the Fund from the close of business on that date through the date on which the Fund’s per share value falls below $0.995. Those shareholders may purchase and redeem shares in their account during the period covered by the Program. However, the number of shares covered by the guarantee cannot exceed the number of shares held by the shareholder at the close of business on September 19, 2008. Thus, to the extent the overall value of a shareholder’s account increases after September 19, 2008, the amount of the increase will not be covered by the guarantee.

The Program provided coverage for a period that was originally due to expire on December 18, 2008, unless extended by the Secretary of the U.S. Treasury. The Secretary of the U.S. Treasury extended the Program until April 30, 2009, and again through September 18, 2009, and the Board decided to continue the Fund’s participation. The Fund bears the expense of its participation in the Program. For the initial three months of the Program, the Fund paid 0.01% based on its net assets as of September 19, 2008. For the coverage beginning on December 19, 2008 and extending through April 30, 2009, the Fund paid 0.015% based on its net assets as of September 19, 2008. For the coverage beginning on May 1, 2009 and extending through September 18, 2009, the Fund paid an additional 0.015% based on its net assets as of September 19, 2008. The Treasury currently is not authorized by Congress to extend the Program past September 18, 2009.

As of the time of this report, assets available in the Program to support all participating money market funds are limited to $50 billion and payments under the Program are dependent on the availability of assets in the Program at the time a request for payment is made. Payments will be made on a first-come-first-serve basis.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees of Natixis Cash Management Trust and Shareholders of Natixis Cash Management Trust — Money Market Series:

In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Natixis Cash Management Trust – Money Market Series (the “Fund”), a series constituting Natixis Cash Management Trust, at June 30, 2009, and the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the 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. An audit 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, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at June 30, 2009 by correspondence with the custodian, provide a reasonable basis for our opinion.

Any subsequent revisions to already pre-approved services or fees (including fee increases) and requests for pre-approval of new services would be presented for consideration quarterly as needed.

If, in the opinion of management, a proposed engagement by the Registrant’s independent accountants needs to commence before the next regularly scheduled Audit Committee meeting, any member of the Audit Committee who is an independent Board member is authorized to pre-approve the engagement, but only for engagements to provide audit, audit related and tax services. This approval is subject to review of the full Audit committee at its next quarterly meeting. All other engagements require the approval of all the members of the audit committee.
