What You Should Know:

Fixed-income securities are subject to credit risk and interest rate risk; their value generally rises when prevailing interest rates fall and falls when rates rise.

The fund can invest a significant percentage of assets in debt securities that are rated below investment grade and the value of fund shares can be adversely affected by changes in economic conditions or other circumstances. Lower rated debt securities have speculative characteristics and may be subject to greater price volatility than higher rated investments. In addition, the secondary market for these securities may lack liquidity. The fund can also invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets, these risks can be significant. Fund shares should be viewed as a long-term investment.

Management Discussion

Investors’ willingness to accept risk continued to increase over the six-month period ended March 31, 2010, and this was reflected in the solid performance of a wide range of non-Treasury sectors in the bond market. At the same time, both the U.S. and global economies showed sustained signs of improvement. In this environment, Loomis Sayles Core Plus Bond Fund benefited because it was well positioned to take advantage of global economic recovery.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles Core Plus Bond Fund returned 4.31%. By comparison, the fund’s benchmark, the Barclays Capital U.S. Aggregate Bond Index, returned 1.99% for the six-month period, while Morningstar’s Intermediate-Term Bond category returned 3.70%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

Strong sector allocation and security selection were the principal contributors to returns, especially in investment-grade and high-yield debt. The lower quality and cyclical biases within these sectors significantly benefited the fund over the period. The fund benefited from its underweight in U.S. government securities, which lagged during the period, and from having a slightly longer maturity than the benchmark.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

The fund’s overweight position in investment-grade bonds was especially beneficial. Within the sector, we favored bonds rated between A and Baa by Moody’s Investors Service. Longer-duration issues and the industrial sector were also key contributors within investment-grade. (Duration is a measure of interest rate sensitivity.) In our high-yield holdings, we focused on bonds issued by companies with proven access to capital markets and solid balance sheets. While we maintained an overweight position in high-yield, we trimmed some positions as they reached what we believed to be fair market value. Within the commercial mortgage-backed securities (CMBS) area, the fund’s focus is on older, high-quality issues that offer a combination of value, attractive income and some protection from the currently adverse commercial real estate environment.

Early in 2010 we added to positions in intermediate-term Mexican and Japanese bonds. We believe the Mexican peso will help increase yield in the fund and the currency is attractive given the moderate recovery conditions we anticipate in the United States. The Japanese yen remains fundamentally undervalued. We believe the yen has the potential to appreciate modestly from current levels and help serve as a partial hedge and offset adverse effects in the event risk goes out of favor and volatility increases.

Throughout the period, we underweighted U.S. Treasuries and avoided Agencies — a positive for the fund. Our security selection among asset-backed securities (ABS) was another positive.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

The fund remained significantly underweight in mortgage-backed securities (MBS) relative to the benchmark. We believe there is limited upside potential in the MBS market; and although performance was slightly punished, our underweight in these securities allowed us to emphasize other sectors that did well.

While our sector allocation to CMBS contributed to return over the past six months, certain security-specific issues weighed modestly on overall outperformance. We remain confident that the issues we selected have the potential to benefit the fund over the long term.

WHAT IS YOUR OUTLOOK?

In general, we have structured the portfolio to benefit from a continuing market recovery, although we have been careful to maintain significant reserves in U.S. Treasuries to provide flexibility if the market gives back some of its recent gains. We remain focused on generating income and plan to selectively add more issue-specific risk into the portfolio. We will look for opportunities to moderately increase high-yield, CMBS and ABS allocations, as well as to shorten duration in anticipation of higher Treasury yields.

PERFORMANCE IN PERSPECTIVE

The charts comparing the fund’s performance to an index provide you with a general sense of how it performed. The fund’s total return for the period shown below appears with and without sales charges and includes fund expenses and fees. An index measures the performance of a theoretical portfolio. Unlike a fund, an index is unmanaged and does not have expenses that affect the results. It is not possible to invest directly in an index. Investors would incur transaction costs and other expenses if they purchased the securities necessary to match the index.

Management Discussion

Investors responded to improving economic conditions by continuing to invest in lower-quality debt securities. Growing confidence in the recovery’s sustainability made risk more acceptable. The resulting strong flow of money into corporate and high-yield issues caused spreads to narrow from the exceptionally wide levels seen during the depths of the recession; by period’s end, spreads had approached 15-year historical averages. Fears over a looming debt crisis in Greece and other peripheral eurozone markets and concerns about China’s lending restrictions percolated through the global credit markets. In the United States, conflicting economic data and an uncertain outlook for financial regulation drove some market participants back into defensive mode for a time. Still, the overall tone in the high-yield market was optimistic, thanks to shrinking default rates and brighter economic trends.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles High Income Fund returned 11.26%. The fund performed in line with its benchmark, Barclays Capital U.S. Corporate High-Yield Bond Index, which returned 11.10% over the period, and ahead of Morningstar’s High Yield Bond category, which had an average return of 10.15%.

WHICH FACTORS CONTRIBUTED POSITIVELY TO THE FUND’S PERFORMANCE?

Convertible securities in the health care and automotive sectors led fund performance over this period, rising along with climbing equity prices. High-yield industrial issues also rose amid indications of increased business activity. Prices for consumer cyclical, non-cyclical and communications credits appreciated as companies cut overhead and posted positive earnings early in the period. Projections of continued economic strengthening also helped buoy holdings in these industries. Bonds rated Baa and B had the greatest positive impact on performance, as investors continued to seek yield throughout the period. Commodity prices pushed higher in anticipation of continued global recovery, benefiting fund holdings based in commodity-rich countries. Bonds denominated in the Mexican peso, Indonesian rupiah and Uruguayan peso were among the top-performing currency exposures.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

While security selection was positive, underweights in strong sectors held back results. Among the below-benchmark exposures that detracted over the period were high-yield financials, including banks and insurance companies. Underweights among C- and Ca-rated issues also penalized returns, as lower-rated issues outperformed those in higher rating categories. Bonds sponsored by government agencies, a minor position in the portfolio, were the sole area of absolute negative returns for the period.

WHAT IS YOUR OUTLOOK?

The fund is positioned to take advantage of a gradual economic recovery and positive fundamental trends. We believe short-term interest rates in the United States will remain low for the foreseeable future, but acknowledge the continuing pressures that the ever-increasing U.S. Treasury issuance will place on longer-term rates. In our opinion, there remains ample opportunity for corporate bond yield spreads to tighten further. Within corporate credit, we are advocating a strategy of specific (fundamental credit) risk instead of market (interest rate) risk. We continue to see opportunity in the convertible market and have focused on increasing our exposure. We continue to add opportunistically to non-U.S. dollar denominated securities, with a focus on credits and countries in which we anticipate fundamental improvements will continue to emerge. We believe that in a rising-rate environment, research and security selection will continue to prove key to successful portfolio management.

Management Discussion

Global bond markets produced uneven results during the six months ended March 31, 2010. A continuing rebound in world economic growth led to solid gains in sectors exposed to credit risk. However, longer-maturity sovereign debt of developed nations, most notably in Europe and Japan, lost ground. The currencies of some developed economies, including the euro and the Japanese yen, also declined. At the same time, the currencies of many commodity-linked national economies in the emerging markets gained as investors grew more confident.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles International Bond Fund returned -1.98%. During the same period, the fund’s benchmark, the Barclays Capital Global Aggregate ex-USD Bond Index, returned -3.18%, while funds in Morningstar’s World Bond category returned an average of 1.35%.

WHAT WAS THE PRIMARY REASON THE FUND’S OUTPERFORMANCE?

The fund’s overall performance reflected the diverse factors affecting bond markets throughout the world during the past six months. Good sector positioning – notably the overweight allocations to corporate bonds – and effective currency strategies helped support results. However, the strength of the U.S. dollar and weak performance by major foreign currencies, including the euro and the British pound, resulted in negative absolute returns both for the fund and the benchmark.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

The fund’s overweight in corporate bonds and its de-emphasis of government bonds and securitized assets proved helpful during a period when corporate securities produced solid gains. In addition, our decisions to underweight the euro and the Japanese yen provided further support as those currencies lost value on world markets. Conversely, the allocations to emerging market investments supported results, with positions in Korea, Indonesia, Malaysia, Brazil and Mexico all producing positive performance for the fund.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

The fund’s positions in longer-maturity U.S. government and domestic corporate bonds lagged shorter-maturity securities, as longer-term interest rates rose more than short-term rates. While overall currency positioning was helpful, exposure to the currencies of Norway and Sweden detracted from results. The euro saw even lower returns due to the impact of government deficit problems in Greece. Overall, investments in government bonds denominated in the home currencies of developed markets such as France, Japan, the Netherlands and Germany were the greatest drags on results.

WHAT IS YOUR OUTLOOK?

We think the global economy will continue to recover during 2010, but we are concerned about 2011 as fiscal problems of many governments threaten to limit the pace of the expansion. Against this backdrop, we continue to favor selected emerging market corporate securities, such as corporate bonds in Indonesia and South Korea. We also may consider adding exposure to the currencies of Malaysia and India. Overall, we favor holding short-maturity high-yield corporate bonds to keep yield in the portfolio until such time as longer-maturity securities offer better value.

Management Discussion

Mortgage- and asset-backed securities posted robust returns during the period. These sectors became significantly undervalued during the financial crisis of 2008. However, investors began to recognize the compelling values they offered early last year. An attractive combination of rising prices and higher yields led to strong performance. Treasuries lagged throughout the period.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles Limited Term Government and Agency Fund returned 3.18%. based on the net asset value of Class A shares. For the same period, the fund’s benchmark, the Barclays Capital U.S. 1-5 Year Government Bond Index, returned 0.92%, while Morningstar’s Short Government category returned 1.15%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

The fund’s holdings in sectors that offered a yield advantage relative to Treasuries, such as mortgage- and asset-backed securities (MBS) and (ABS), were the principal drivers of performance. These sectors had been significantly undervalued due to concerns about real estate and mortgages. However, in the second quarter of 2009, investors began to recognize the compelling value of these securities. Risk preference shifted away from safety, leading to relative price appreciation in securitized assets. Overall, the combination of rising prices and significant yield advantage led to strong performance in these sectors. In order of their impact on the fund’s return, securities backed by commercial mortgages (CMBS) were the largest contributors to return, followed by ABS and then MBS related to government-sponsored entities (GSEs).

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

As the sectors that had provided the most support for the fund during the financial crisis became underperformers, we gradually positioned the fund more aggressively. We modestly increased holdings in CMBS, which continue to see good demand coupled with low supply. These factors bolstered price movement, leading to significant gains throughout the period. We also maintained an overweight in ABS because of their attractive yields and further appreciation potential.

The fund’s holdings in Treasury Inflation-Protected Securities (TIPS) also performed well. With the continued improvement in the economic outlook late in 2009 and early 2010, concerns about deflation began to ease, resulting in higher valuations for TIPS. We sold the fund’s TIPS holdings on strength during the fourth quarter of 2009.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Treasuries were underperformers for the fund during the period, as investors grew more comfortable with risk and shifted into higher-yielding issues. Though a significant portfolio underweight relative to the benchmark allowed for a positive contribution from Treasuries, results were weak compared to other portfolio holdings. In addition, longer-maturity securities lagged shorter-maturity securities, as longer-term interest rates rose more than short-term rates.

WHAT IS YOUR OUTLOOK?

Although we expect the Federal Reserve Board to raise short-term interest rates, we believe the first rate increase will occur later than the market thinks it will. We expect our GSE mortgage positions to benefit from a stable interest-rate environment. As a result, we modestly increased CMBS holdings and plan to maintain an overweight in both CMBS and ABS until market conditions warrant a change. We continue to favor ABS and MBS because they are protected through credit enhancements intended to absorb losses and protect senior securities. We believe this protection is strong. Within the fund’s investment parameters, we will continue to look for opportunities to take advantage of a steep yield curve and will focus on income over price appreciation.

Given our expectations of a gradual rise in yields and slow economic growth, we believe our strategy, coupled with careful security selection, has the potential to provide attractive returns for shareholders. As always, we are watching incoming data for signs that market conditions have changed.

What You Should Know:

Fixed-income securities are subject to credit risk and interest rate risk; their value generally rises when prevailing interest rates fall and falls when rates rise.

Management Discussion

As the world economy continues to recover slowly, investors replaced lingering pessimism with optimism. Still fears about government debt in Europe and China’s tight lending practices percolated through the global credit markets, tempering investor enthusiasm for overseas obligations. In the United States, wavering economic data and an uncertain outlook for financial regulation drove some market participants back into defensive mode. Despite these challenges, improved access to capital, declining corporate default rates and brighter economic trends fed an appetite for risk, and corporate bond spreads narrowed during the period.

For the six month period ended March 31, 2010, Class A shares of Loomis Sayles Strategic Income Fund returned 9.86%. The fund significantly outperformed its benchmark, the Barclays Capital U.S. Aggregate Bond Index, which returned 1.99% over the period. It also outperformed the average fund in Morningstar’s Multisector Bond category, which returned 6.82%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

Successful security selection was the key to the period’s impressive results, with investment-grade and high-yield corporate issues, convertible bonds and non-U.S dollar obligations all contributing to the fund’s strong performance relative to its benchmark.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

Strong corporate earnings and better-than-expected fourth quarter gross domestic product (GDP) growth buoyed results among investment-grade corporate issues. Notable returns came from industrial issues in technology, transportation and capital goods. Certain investment-grade financial and electric utility names also lifted performance. Despite a few periods of muted performance, high yield garnered the most gains for the fund, as investors were willing to accept greater risk in pursuit of higher yields. Within high yield, financial (consumer finance, diversified finance) and industrial (technology, communications, retail, automotive) names drove outperformance.

The fund’s non-U.S dollar allocation was among the top contributors of excess return. Investments denominated in the Canadian dollar, Indonesian rupiah and Mexican peso benefited from both asset and currency appreciation. The fund’s Australian dollar, Brazilian real, British pound and New Zealand dollar holdings also contributed.

The equity market rally that started in 2009 extended into 2010, lending support for convertible bonds. Our increased allocation to convertibles generated some of the best returns for the period, led by selected names in automotive, pharmaceuticals and technology. Modest exposure to preferred and equity securities also benefited from the performance surge.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

There were few areas of weakness that existed in the fund amid the widespread bullish sentiment that swept fixed-income markets over the last several months. Our bias away from commercial mortgage-backed securities (CMBS) detracted from performance as the sector rallied. Currency weakness was a performance drag for holdings denominated in the Icelandic krona and Norwegian krone.

WHAT IS YOUR OUTLOOK?

The fund is positioned to take advantage of a gradual economic recovery and positive fundamental trends. We believe short-term interest rates in the United States will remain low for the foreseeable future, but acknowledge the continuing pressures that the ever-increasing U.S. Treasury issuance will place on longer-term rates. In our opinion, there remains ample opportunity for corporate bond yield spreads to tighten further. Within corporate credit, we are advocating a strategy of specific (fundamental credit) risk instead of market (interest rate) risk. We continue to see opportunity in the convertible market and have focused on increasing our exposure. We continue to add opportunistically to non-U.S. dollar-denominated securities, with a focus on credits and countries in which we anticipate fundamental improvements will continue to emerge. We believe that in a rising-rate environment, research and security selection will continue to prove key to successful portfolio management.

UNDERSTANDING FUND EXPENSES

As a mutual fund shareholder, you incur different costs: transaction costs, including sales charges (loads) on purchases, contingent deferred sales charges on redemptions; certain exchange fees; and ongoing costs, including management fees, distribution and/or service fees (12b-1 fees), and other fund expenses. In addition, each fund may assess a minimum balance fee of $20 on an annual basis for accounts that fall below the required minimum to establish an account. Certain exemptions may apply. These costs are described in more detail in the funds’ prospectuses. The examples below are intended to help you understand the ongoing costs of investing in the funds and help you compare these with the ongoing costs of investing in other mutual funds.

The first line in the table of 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 October 1, 2009 through March 31, 2010. 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 = 8.60) 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 of 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 such as sales charges redemption fees, or exchange fees. Therefore, the second line in the table of each fund 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.

NOTESTO FINANCIAL STATEMENTS

March 31, 2010 (Unaudited)

1. Organization. Natixis Funds Trust I and Loomis Sayles Funds II (the “Trusts” and each a “Trust”) are each organized as a Massachusetts business trust. Each Trust is registered under the Investment Company Act of 1940, as amended (“1940 Act”), as an open-end management investment company. Each Declaration of Trust permits the Board of Trustees to authorize the issuance of an unlimited number of shares of the Trust in multiple series. The financial statements for certain funds of the Trusts are presented in separate reports. The following funds (individually, a “Fund” and collectively, the “Funds”) are included in this report:

Natixis Funds Trust I:

Loomis Sayles Core Plus Bond Fund (the “Core Plus Bond Fund”)

Loomis Sayles Funds II:

Loomis Sayles High Income Fund (the “High Income Fund”)

Loomis Sayles International Bond Fund (the “International Bond Fund”)

Loomis Sayles Limited Term Government and Agency Fund (the “Limited Term Government and Agency Fund”)

Loomis Sayles Strategic Income Fund (the “Strategic Income Fund”)

The Funds each offer Class A, Class C and Class Y shares. Effective February 1, 2010, Strategic Income Fund began offering Admin Class 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.

Class A shares of all Funds except Limited Term Government and Agency Fund are sold with a maximum front-end sales charge of 4.50%. Class A shares of Limited Term Government and Agency Fund are sold with a maximum front-end sales charge of 3.00%. Class B shares do not pay a front-end sales charge, but pay higher Rule 12b-1 fees than Class A shares for eight years (at which point they automatically convert to Class A shares), and are subject to a contingent deferred sales charge (“CDSC”) if those shares are redeemed within six years of purchase. Class C shares do not pay a front-end sales charge, do not convert to any other Class of shares and pay higher Rule 12b-1 fees than Class A shares and may be subject to a CDSC of 1.00% if those shares are redeemed within one year of acquisition except for reinvested distributions. Class Y shares do not pay a front-end sales charge, a CDSC or Rule 12b-1 fees. Class Y shares are generally intended for institutional investors with a minimum initial investment of $100,000, though some categories of investors are exempted from the minimum investment amount as outlined in the Fund’s Prospectus. Admin Class shares do not pay a front-end sales charge or a CDSC, but do pay a Rule 12b-1 fee. Admin Class shares are offered exclusively through intermediaries.

Most expenses of the Trusts can be directly attributed to a fund. Expenses which cannot be directly attributed to a fund are generally apportioned based on the relative net assets of each of the funds in the Trusts. Expenses of a Fund are borne pro rata by the holders of each class of shares, except that each class bears expenses unique to that class (including the Rule 12b-1 service and distribution fees). In addition, each class votes as a class only with respect to its own Rule 12b-1 Plan. Shares of each class would receive their pro rata share of the net assets of a 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 each Fund in the preparation of its financial statements. The Funds’ 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 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. Debt securities (other than short-term obligations purchased with an original or remaining maturity of sixty days or less) are generally valued on the basis of evaluated bids furnished to the Funds by a pricing service recommended by the investment adviser and approved by the Board of Trustees, which service determines valuations for normal, institutional-size trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders. Equity securities, including shares of closed-end investment companies and exchange-traded funds, for which market quotations are readily available are valued at market value, as reported by pricing services recommended by the investment adviser and approved by the Board of Trustees. Such pricing services generally use the security’s last sale price on the exchange or market where the security is primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking a NOCP, at the most recent bid quotation on the applicable NASDAQ market. Broker-dealer bid quotations may also be used to value debt and equity securities where a pricing service does not price a security or where a pricing service does not provide a reliable price for the security. In instances where broker-dealer bid quotations are not available, certain securities held by the Funds may be valued on the basis of a price provided by a principal market maker. Forward foreign currency contracts are valued utilizing interpolated prices determined from information provided by an independent pricing service. Short-term obligations purchased with an original or remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Funds’ investment adviser using consistently applied procedures under the general supervision of the Board of Trustees. Investments in other open-end investment companies are valued at their net asset value each day.

Certain Funds may hold securities traded in foreign markets. Foreign securities are valued at the market price in the foreign market. However, if events occurring after the close of the foreign market (but before the close of regular trading on the New York Stock Exchange) are believed to materially affect the value of those securities, such securities

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

are fair valued pursuant to procedures approved by the Board of Trustees. When fair valuing securities, the Funds may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Funds calculate their net asset values.

b. Security Transactions and Related Investment Income. Security transactions are accounted for on trade date. Dividend income is recorded on ex-dividend date, or in the case of certain foreign securities, as soon as a Fund is notified, 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. Periodic principal adjustments for inflation-protected securities are recorded to interest income. Negative principal adjustments (in the event of deflation) are recorded as reductions of interest income to the extent of interest income earned, not to exceed the amount of positive principal adjustments on a cumulative basis. Distributions received from investments in securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments or as a realized gain, respectively. The calendar year-end amounts of ordinary income, capital gains, and return of capital included in distributions received from the Funds’ investments in real estate investment trusts (“REITs”) are reported to the Funds after the end of the fiscal year; accordingly, the Funds estimate these amounts for accounting purposes until the characterization of REIT distributions is reported to the Funds after the end of the fiscal year. Estimates are based on the most recent REIT distribution information available. Investment income is recorded net of foreign taxes withheld when applicable. In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. Investment income, non-class specific expenses and realized and unrealized gains and losses are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund.

c. Foreign Currency Translation. The books and records of the Funds are maintained in U.S. dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the period. Purchases and sales of investment securities, income and expenses are translated on the respective dates of such transactions.

Since the values of investment securities are presented at the foreign exchange rates prevailing at the end of the period, it is not practical to isolate that portion of the results of operations arising from changes in exchange rates from fluctuations which arise due to changes in market prices of investment securities. Such changes are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currency, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Funds’ books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities, other than investment securities, at the end of the fiscal period, resulting from changes in exchange rates.

Each Fund may use foreign currency exchange contracts to facilitate transactions in foreign-denominated investments. Losses may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.

d. Forward Foreign Currency Contracts. Each Fund may enter into forward foreign currency contracts. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell generally are used to hedge a Fund’s investments against currency fluctuation. Also, a contract to buy or sell can offset a previous contract. These contracts involve market risk in excess of the unrealized gain or loss reflected in the Funds’ Statements of Assets and Liabilities. The U.S. dollar value of the currencies a Fund has committed to buy or sell represents the aggregate exposure to each currency the Fund has acquired or hedged through currency contracts outstanding at period end. Gains or losses are recorded for financial statement purposes as unrealized until settlement date. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. Certain contracts may require the movement of cash or securities to or from the counterparty as collateral for the Funds’ or counterparty’s net obligations under the contracts.

e. Federal and Foreign Income Taxes. Each Trust treats each fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2010 and has concluded that no provisions for income tax are required. The Funds’ federal tax returns for the prior three fiscal years, where applicable, 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 six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. 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.

protected bond adjustments, premium amortization, defaulted bond adjustments, paydown gains and losses, distribution redesignations, expired capital loss carryforwards and return of capital and capital gains distributions from REITS. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts. Temporary differences between book and tax distributable earnings are primarily due to deferred Trustees’ fees, wash sales, premium amortization accruals, forward contracts mark to market, dividends payable, securities lending collateral gain/loss adjustment, REIT basis adjustments, discount accretion on inflation-protected securities and defaulted bond interest. Distributions from net investment income and short-term capital gains are considered to be distributed from ordinary income for tax purposes.

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2009 was as follows:


	2009 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Core Plus Bond Fund	$	12,015,697	$	—	$	12,015,697
High Income Fund		7,740,530		—		7,740,530
International Bond Fund		334,030		—		334,030
Limited Term Government and Agency Fund		5,789,887		—		5,789,887
Strategic Income Fund		725,851,869		52,952,003		778,803,872

Differences between these amounts and those reported in the Statements of Changes in Net Assets, if any, are primarily attributable to different book and tax treatment for short-term capital gains.

As of September 30, 2009, the capital loss carryforwards and post-October losses were as follows:


	Core Plus Bond Fund			High Income Fund			International Bond Fund			Limited Term Government and Agency Fund			Strategic Income Fund

g. Repurchase Agreements. It is each 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. Certain 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.

h. Securities Lending. The Funds have entered into an agreement with State Street Bank and Trust Company (“State Street Bank”), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value (including accrued interest) of the loaned international or domestic securities, respectively, when the loan is initiated. Thereafter, the value of the collateral must remain at least 102% of the market value (including accrued interest) of loaned securities for U.S. equities and U.S. corporate debt; at least 105% of the market value (including accrued interest) of loaned securities for non-U.S. equities; and at least 100% of the market value (including accrued interest) of loaned securities for U.S. Government securities, sovereign debt issued by non-U.S. Governments and non-U.S. corporate debt. In the event that the market value of the collateral falls below the required percentages described above, the borrower will deliver additional collateral on the next business day. As with other extensions of credit, the Funds bear the risk of loss with respect to the investment of the collateral. The Funds invest cash collateral in short-term investments, a portion of the income from which is remitted to the borrowers and the remainder allocated between the Funds and State Street Bank as lending agent.

As of March 31, 2010, there were no securities on loan. Excess collateral in the amount of $2,993,578 related to terminated loans with a bankrupt borrower, is held by State Street Bank on behalf of Strategic Income Fund. This amount is expected to be returned to the bankruptcy administrator before the end of the Fund’s fiscal year at September 30, 2010.

i. Delayed Delivery Commitments. Purchases of delayed delivery instruments may have a similar effect on a Fund’s net asset value as if the Fund had created a degree of leverage in its portfolio. The price of the underlying instruments and the date when they will be paid for are fixed at the time the transaction is negotiated. If a Fund enters into such a transaction, collateral consisting of liquid securities or cash and cash equivalents will be maintained in an amount at least equal to the commitment with the custodian and/or broker. Losses may arise due to changes in the market value of the underlying instruments or if the counterparty does not perform under the contract.

j. Indemnifications. Under the Trusts’ organizational documents, their officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ 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 Funds expect the risk of loss to be remote.

3. Fair Value Measurements. In accordance with accounting standards related to fair value measurements and disclosures, the Funds have categorized the inputs utilized in determining the value of each Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

•

Level 1 – quoted prices in active markets for identical assets or liabilities;

•

Level 2 – prices determined using other significant inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar assets or liabilities, 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 asset or liability (unobservable inputs reflect each Fund’s own assumptions in determining the fair value of assets or liabilities 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 Funds’ investments as of March 31, 2010, at value:

4. Derivatives. Derivative instruments are defined as financial instruments whose value and performance are based on the value and performance of another security or financial instrument. Derivative instruments that the Funds currently use include forward foreign currency contracts.

The Funds are subject to the risk that changes in foreign currency exchange rates will have an unfavorable effect on the value of Fund assets denominated in foreign currencies. The Funds may enter into forward foreign currency contracts for hedging purposes to protect the value of the Funds’ holdings of foreign securities. The Funds may also use forward foreign currency contracts to gain exposure to foreign currencies, regardless of whether securities denominated in such currencies are held in the Funds. During the six months ended March 31, 2010, High Income Fund engaged in forward foreign currency contract transactions for hedging purposes. During this same period, International Bond Fund engaged in forward foreign currency contract transactions for hedging purposes and to gain exposure to foreign currencies.

Each Fund is party to agreements with counterparties that govern transactions in forward foreign currency contracts. These agreements contain contingent features that allow the counterparties to terminate open contracts early if the net asset value of a Fund declines beyond a certain threshold. If such contingent features were to be triggered, the counterparties could request immediate settlement of open contracts at current fair value.

d. Sub-Transfer Agent Fees.

Accordingly, the Funds 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 Funds would have paid its transfer agent had each customer’s shares been registered directly with the transfer agent instead of held through the intermediaries.

Effective January 1, 2010, the Chairperson of the Board receives a retainer fee at the annual rate of $250,000.

Each member of the ad hoc Committee on Alternative Investments received a one-time fee of $10,000. The ad hoc Committee on Alternative Investments is not a standing committee. These fees are allocated among the funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts and 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.

Prior to January 1, 2010, the Chairperson of the Board received a retainer fee at the annual rate of $200,000. The Chairperson did not receive any meeting attendance fees for Board of Trustees meetings or committee meetings that she attended. Each Independent Trustee (other than the Chairperson) received, in the aggregate, a retainer fee at the annual rate of $65,000. Each Independent Trustee also received a meeting attendance fee of $7,500 for each meeting of the Board of Trustees that he or she attended in person and $3,750 for each meeting of the Board of Trustees that he or she attended telephonically. In addition, each committee chairman received an additional retainer fee at an annual rate of $10,000.

A deferred compensation plan (the “Plan”) is available to the Trustees on a voluntary basis. Deferred amounts remain in the Funds 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 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 normally reflected as Trustees’ fees and expenses in the Statements of Operations. The portions of the accrued obligations allocated to the Funds under the Plan are reflected as Deferred Trustees’ fees in the Statements of Assets and Liabilities.

g. Payments by Affiliates. For the six months ended March 31, 2010, Loomis Sayles reimbursed the Strategic Income Fund $76,238 for losses incurred in connection with a trading error.

7. Line of Credit. Each 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 committed unsecured 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, plus 1.25%. In addition, a commitment fee of 0.15% 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 10, 2010, each 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 committed unsecured 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 greater of the Federal Funds rate or overnight LIBOR, plus 0.75%. In addition, a commitment fee of 0.125% 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 six months ended March 31, 2010, the Funds had no borrowings under these agreements.

8. Concentration of Risk. International Bond Fund is a non-diversified fund. Compared with diversified mutual funds, the International Bond Fund may invest a greater percentage of its assets in a particular country. Therefore, the International Bond Fund’s returns could be significantly affected by the performance of any one of the small number of countries in its portfolio.

Each Fund may purchase investments of foreign issuers. Investing in securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies and securities of the U.S. Government. These risks include revaluation of currencies and the risk of expropriation. Moreover, the markets for securities of many foreign issuers may be less liquid and the prices of such securities may be more volatile than those of comparable U.S. companies and the U.S. Government.

9. Concentration of Ownership. At March 31, 2010, the Loomis Sayles Employees’ Profit Sharing Retirement Plan held 23,063 shares of beneficial interest of Limited Term Government and Agency Fund and Natixis US owned shares equating to 18.75% of International Bond Fund’s net assets.

10. Capital Shares. Each Fund may issue an unlimited number of shares of beneficial interest, without par value. Transactions in capital shares were as follows:

What You Should Know:

Growth stocks are generally more sensitive to market movements than value stocks. The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. Fund shares should be viewed as a long-term investment.

Management Discussion

Equities generally marched ahead during the six months ended March 31, 2010, sustaining a rally that began in early 2009. The period began with the stock market producing solid gains in the final three months of 2009. While the rally paused during the first two months of 2010, signs of an improving economy increased investors’ appetite for risk in March and the rally returned. Gains in equity prices tended to be broad-based, with economically-sensitive sectors producing the best relative returns while defensive areas lagged.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles Disciplined Equity Fund returned 9.57%. During the same period, the fund’s benchmark, the S&P 500 Index, returned 11.75%, while funds in Morningstar’s Large Growth category returned an average 11.38%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S UNDERPERFORMANCE?

The fund essentially matched the S&P 500 Index during the final three months of 2009, but lost ground during the first quarter of 2010. The primary reason for this underperformance was our emphasis on valuation and company quality – as reflected by factors such as balance sheet strength – during a period in which higher-risk, “momentum” stocks tended to turn in the strongest relative performance. In addition, individual stock selection, particularly in the energy and consumer staples sectors, held back overall results. During the period, we introduced the use of trading in call options – a form of equity derivatives – to manage risk and generate yield. The performance of these trades was in line with the fund’s overall results.

WHICH FACTORS CONTRIBUTED POSITIVELY TO FUND PERFORMANCE?

Holdings in the information technology, utilities and industrials sectors all helped support performance. Aided by a global economic expansion, technology companies experienced rebounding sales and increasing merger-and-acquisition activity. The sector’s solid balance sheets also attracted investors. Within the information technology group, Oracle, Apple and Hewlett-Packard did especially well. Software company Oracle successfully completed its acquisition of Sun Microsystems, while Apple enjoyed strong sales of its iPhone and personal computer products. Hewlett-Packard, meanwhile, saw steady gains in personal computers and corporate enterprise spending. Our success in utilities came from a decision to protect the fund against the threat of declining power prices. The top individual utility investment was Constellation Energy, which traded at a discounted price at the start of the period and outperformed the overall utilities sector due to specific business catalysts.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Our investments in the energy and consumer staples sectors did not help performance. In energy, we did not invest early enough in two of the better-performing stocks, Anadarko Petroleum (sold from the portfolio), an independent exploration and production company, and Williams Companies, a natural gas corporation. In the same sector, positions in Marathon Oil, Pride International and Transocean also lagged. Pride was sold. Poor performance among the fund’s consumer staples holdings in the fourth quarter of 2009 held back results for the entire period. Disappointing staples positions included Whole Foods Market, Dr. Pepper Snapple, Avon Products and SUPERVALU. For the fund as a whole, the most notable individual detractors included QUALCOMM, a technology company whose share price fell after reporting disappointing quarterly results, and Owens-Illinois, a glass manufacturer affected by slumping sales. All of these poor performers were sold.

WHAT IS YOUR OUTLOOK?

We believe the stock market has the potential to produce positive returns over the next 12 months, although overall gains may be modest and interrupted by periodic reversals. Corporate cost-cutting programs have been responsible for most of the earnings growth that has occurred up until now. We believe the economy has stabilized, setting the stage for revenue improvements that can drive future profit growth. However, improved earnings also can trigger talk of higher interest rates, which, in turn, could restrain overall market performance.

PERFORMANCE IN PERSPECTIVE

The charts comparing the fund’s performance to an index provide you with a general sense of how it performed. The fund’s total return for the period shown below appears with and without sales charges and includes fund expenses and fees. An index measures the performance of a theoretical portfolio. Unlike a fund, the index is unmanaged and does not have expenses that affect the results. It is not possible to invest directly in an index. Investors would incur transaction costs and other expenses if they purchased the securities necessary to match the index.

What You Should Know:

The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. The fund can invest a significant percentage of assets in debt securities that are rated below investment grade and the value of fund shares can be adversely affected by changes in economic conditions or other circumstances. In addition, the secondary market for these securities may lack liquidity. Fund shares should be viewed as a long-term investment.

Management Discussion

Equity markets around the world delivered solid returns during the six months ended March 31, 2010, as a global economic recovery continued to gain traction. Global bond markets produced uneven results. Sectors exposed to credit risk benefited from improved economic conditions. However, the longer-maturity sovereign debt of eurozone countries lost ground under a cloud of debt problems, and Japan’s bond market also suffered.

In this environment, Class A shares of Loomis Sayles Global Markets Fund returned 10.28%, for the six months ended March 31, 2010. For the same period, the fund’s primary benchmark, the MSCI World Index (common stocks from developed countries around the world) returned 7.67% while its secondary benchmark, Citigroup World Government Bond Index (government bonds issued in the United States and other developed countries) returned -3.23%. The average return on the funds in Morningstar’s World Allocation category was 5.38%. Both the equity and bond portions of the fund performed well for the period, reflecting strong markets for U.S. dollar-denominated bonds and vigorous gains in the stock market.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

Security selection on both the bond and stock sides generally accounted for the fund’s performance advantage over the index and peer group average. Sector and currency allocations in fixed-income gave the fund a comfortable edge over these comparative measures during the period.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

Within the equity portion of the portfolio, consumer discretionary and information technology stocks performed particularly well during the period. Priceline.com and Amazon.com were among the fund’s top performers. Amazon benefited from expanded product offerings, including the Kindle digital reader. Priceline was up after the company beat its own earnings estimates. Apple was another solid performer as the company recently reported its best quarter ever.

During the period, we continued to focus on strong, fundamentally-driven opportunities around the world. We added to positions in companies with improving earnings outlooks as we trimmed or eliminated holdings showing signs of weakness. The most notable change in our sector weights was a reduction in financial stocks.

Within the bond portion of the portfolio, security selection and country allocations were positives. High-yield corporate issues denominated in U.S. dollars were among the best performers, and an overweight in this area helped. We kept our focus on shorter-maturity, high-yield corporate bonds to keep yield in the higher ranges until securities with longer maturities offer better value. Emerging markets also benefited returns.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Some disappointing industrial stocks detracted from performance. Highly regarded Spanish wind turbine manufacturer Gamesa fell on weakness in the turbine market. Volvo shares declined when the company reported a drop in sales late in 2009 and an anticipated improvement in volume appeared to stall out. Piraeus Bank, QUALCOMM and Southwestern Energy also detracted from performance. The Greek debt crisis hurt Piraeus. We sold Gamesa, Volvo and Piraeus and trimmed our position in Southwestern Energy as its price fell amid pricing concerns for natural gas. Wireless chipmaker QUALCOMM reported disappointing earnings and also was sold from the portfolio.

Corporate bonds with longer maturities were weak. However, the fund’s duration – a measure of interest-rate sensitivity – was shorter than the duration of its benchmark, which aided relative performance. The fund’s exposure to weaker currencies – namely the Norwegian krone and the Polish zloty – also detracted from returns. The weakest performers on the bond side were lower-yielding government bonds denominated in the euro, the Japanese yen and the British pound.

What You Should Know:

Growth stocks are generally more sensitive to market movements because their stock prices are based on future expectations. Frequent portfolio turnover may result in increased tax liabilities that will reduce the fund’s overall return. The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. Fund shares should be viewed as a long-term investment.

Management Discussion

Equity investments produced generally solid returns during the six months ended March 31, 2010, although the recovery in stock prices was interrupted in January 2010 as investors absorbed the gains produced in 2009. However, new evidence indicating an improving economy increased investors’ confidence as well as their appetite for risk and the rally reignited in March. Stocks in economically sensitive groups generally produced the best relative returns, while stocks in defensive areas tended to lag.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles Growth Fund returned 14.51%. During the same period, the fund’s benchmark, the Russell 1000 Growth Index, returned 12.96%, while funds in Morningstar’s Large Growth category returned an average 11.38%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

Stock selection drove the fund’s solid relative results, especially in the consumer discretionary, materials and health care sectors. The strong performance came despite disappointing returns from financials holdings. Over the period, we continued to follow our longer-term strategy, seeking select large-cap growth companies with solid fundamentals and leading products in their competitive markets. The primary changes we made during the six months were to increase an overweight in consumer discretionary stocks, while reducing our emphasis on financial companies. We maintained an overweight in information technology.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

Among consumer discretionary holdings, performance was particularly favorable for on-line travel company Priceline.com and on-line retailer Amazon.com, both of which reported healthy earnings improvements. The expansion of Priceline.com’s travel business was particularly noteworthy in Europe, while Amazon.com succeeded by expanding its product offerings. In the materials sector, the standout performer was Cliffs Natural Resources, an international mining corporation that reaped solid gains as global demand for iron ore improved. Apple was the best-performing information technology holding, as it reported its best-ever quarter after setting sales records for both personal computers and smart phones.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Our holdings in the financial services and producer durable industries generated disappointing returns. Among financials, banks Goldman Sachs and JPMorgan Chase performed poorly as investors pulled back and took gains from the stocks’ earlier rallies. Market concerns also arose over the potential effects of proposed new financial regulations on companies such as Goldman Sachs. In the producer durables group, valve manufacturer Flowserve encountered stiff pricing pressure, causing a slight decline in the company’s share price. We sold the stock. Other poor performers included two information technology companies: QUALCOMM, which produces operating systems for wireless communications, and Brocade, which develops and markets hardware and software products for data networks. We sold both QUALCOMM and Brocade before the end of the period.

What You Should Know

Small- and mid-cap stocks may be more volatile than larger, more established companies. The secondary market for these stocks may be less liquid, which could adversely impact the fund’s value. Growth funds involve increased risks, in part, because the value of the underlying securities is based on future expectations that may or may not be met. The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. The fund is subject to currency decline. Fund shares should be viewed as a long-term investment.

Management Discussion

The stock market generated broad-based positive returns for the period, even though it pulled back early in 2010 before regaining its footing in March. Economic data improved, and confident investors drove returns higher across most sectors of the market.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles Mid Cap Growth Fund returned 17.88%. The fund outperformed its benchmark, the Russell Midcap Growth Index, which returned 14.88%, and the 12.89% average return of funds in its peer group, the Morningstar Mid-Cap Growth category. Gains made early in the period helped the fund hold onto its lead even during a period of market weakness, as the fund’s ratio of winners to losers was substantial. The stop-loss discipline we had in place prompted us to sell underperformers and redirect assets to winners.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

Strong stock selection across most sectors aided returns. From a sector standpoint, producer durables had the most positive impact on the fund’s returns, followed by technology. Some of our biggest winners in durables were companies exposed to natural resources. Leading this group was Bucyrus International, which provides mining equipment and services to customers worldwide. Bucyrus’ rapid growth also reflects its participation in emerging markets.

Winners in technology included communications equipment businesses, such as F5 Networks, which offers cost-saving internet traffic management solutions, and electronics companies such as Cree, a leading manufacturer of light-emitting diode (LED) chips and components. Sales of Cree’s product lines reflected growing demand for energy-saving lighting equipment.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

In addition to technology, e-commerce stocks were winning themes among the fund’s consumer discretionary holdings. Specialty retail and apparel stocks such as Lululemon Athletica and Guess?, both of which continue to show strong earnings momentum, also helped results. Other top-performing individual stocks included Priceline.com, a leading online travel company. Despite a global recession, Priceline.com continues to enjoy vigorous growth, driven by its European travel bookings.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Financial services was one of the fund’s only groups with negative performance for the six-month period. Ill-timed stock selections included investment managers Janus Capital Group and SVB Financial. Both positions were closed during the period. The stocks we picked in the materials sector were positive, but we were underweight in the sector, which generated solid performance. Our healthcare selections provided positive absolute returns, but they lagged the benchmark’s healthcare holdings in the first quarter of 2010. Almost half the fund’s shortfall in healthcare came from biotech companies, where several of our stocks experienced corrections.

Among individual stock holdings, our greatest disappointments included biotechnology company Illumina. It was one of our big winners early in 2009, but the company’s subsequent earnings were disappointing. The stock was sold during the period. Fibria Celulose, a Brazilian producer of pulp and paper products, declined sharply on balance-sheet concerns. This caused our stop-loss program to kick in and the position was eliminated. Fuqi International, a leading Chinese jewelry manufacturer, exemplifies one of our favorite macro themes: rising middle-class consumption in emerging markets. However, the company reported a disappointing quarter, and the stock was sold when it reached our stop-loss price.

What You Should Know:

While the fund offers potential for long-term capital growth, it invests in value stocks, which can fall out of favor with investors and may underperform growth stocks during certain market conditions. The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. Fund shares should be viewed as a long-term investment.

Management Discussion

The stock market rally continued into the fourth quarter of 2009, then paused briefly early this year as investors sought further indications that the economic recovery might be sustainable. In March, improving housing, employment and manufacturing data fed renewed bullishness and an increasing appetite for risk that drove up stocks, especially in economically-sensitive sectors.

Loomis Sayles Value Fund trailed both its benchmark and Morningstar peer group. For the six months ended March 31, 2010, Class A shares provided a total return of 9.42%. The fund’s benchmark, the Russell 1000 Value Index, returned 11.28%, while the average return on the funds in Morningstar’s Large Value category was 10.75%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S UNDERPERFORMANCE?

Stock selection within the producer durables and healthcare sectors generally accounted for the shortfall relative to the index.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

As investors spurned more defensive market segments in pursuit of greater gains, an underweight in utilities contributed to relative results. It also helped the fund to have less exposure than the index to AT&T, a laggard stock and a large holding in the fund’s benchmark. AT&T was sold during the period. In utilities, American Electric Power performed well, thanks to its attractive valuation as well as favorable regulatory environments in its service areas. Below-benchmark stakes in energy and financials also were beneficial. Among individual holdings, Smith International, an oil field service company, rose sharply on news of its pending acquisition by industry leader Schlumberger; the combined company is well-positioned to benefit from the growing complexity of global oil and gas production. Smith reported strong fourth-quarter revenue gains in all of its operating segments, highlighting the breadth of the recovery and possibly auguring well for 2010. Financial planning specialist Ameriprise and PNC Financial, a diversified financial company, both delivered strong returns. Estee Lauder continued to surprise skeptics with very good earnings reports. Shares of Northrop Grumman rebounded from depressed levels as it rebuilt its Louisiana shipyard following hurricane damage. Moreover, most defense contractors have performed well, based on appealing valuations and budgets that remain robust in the face of world tensions.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Several individual stocks held back performance in the producer durables, health care and materials sectors. Medical device maker Boston Scientific suffered an important product recall and also tempered its growth projections. We think the market has taken an overly negative view of Boston Scientific’s new management team. Foster Wheeler, an engineering and construction firm, also reduced its earnings forecast. In addition, investors reacted negatively when new contract awards failed to reach anticipated levels. We sold long-term holding, beer-maker Molson Coors, due to concerns about a resumption of price wars with its competitors.

UNDERSTANDING FUND EXPENSES

As a mutual fund shareholder, you incur different types of costs: transaction costs, including sales charges (loads) on purchases and contingent deferred sales charges on redemptions, certain exchange fees and ongoing costs, including management fees, distribution and/or service fees (12b-1 fees), and other fund expenses. In addition, each fund may assess 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 funds’ prospectus. The examples below are intended to help you understand the ongoing costs of investing in the funds 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 amount of fund expenses you would have paid on a $1,000 investment in the fund from October 1, 2009 through March 31, 2010. 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 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 of each fund 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.

NOTESTO FINANCIAL STATEMENTS

March 31, 2010 (Unaudited)

1. Organization. Loomis Sayles Funds II (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 Board of Trustees to authorize the issuance of an unlimited number of shares of the Trust in multiple series. The financial statements for certain funds of the Trust are presented in separate reports. The following funds (individually, a “Fund” and collectively, the “Funds”) are included in this report:

Loomis Sayles Disciplined Equity Fund (the “Disciplined Equity Fund”)

Loomis Sayles Global Markets Fund (the “Global Markets Fund”)

Loomis Sayles Growth Fund (the “Growth Fund”)

Loomis Sayles Mid Cap Growth Fund (the “Mid Cap Growth Fund”)

Loomis Sayles Value Fund (the “Value Fund”)

Each Fund offers Class A, Class C and Class Y shares. Effective February 1, 2010, the Value Fund began offering Admin Class 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.

Class A shares are sold with a maximum front-end sales charge of 5.75%. Class B shares do not pay a front-end sales charge, but pay higher Rule 12b-1 fees than Class A shares for eight years (at which point they automatically convert to Class A shares), and are subject to a contingent deferred sales charge (��CDSC”) if those shares are redeemed within six years of purchase. Class C shares do not pay a front-end sales charge, do not convert to any other class of shares and pay higher Rule 12b-1 fees than Class A shares and may be subject to a CDSC of 1.00% if those shares are redeemed within one year of acquisition, except for reinvested distributions. Class Y shares do not pay a front-end sales charge, a CDSC or Rule 12b-1 fees. Class Y shares are generally intended for institutional investors with a minimum initial investment of $100,000, though some categories of investors are exempted from the minimum investment amount as outlined in the Funds’ Prospectus. Admin Class shares do not pay a front-end sales charge or a CDSC, but do pay a Rule 12b-1 fee. Admin Class shares are offered exclusively through intermediaries.

Most expenses of the Trust can be directly attributed to a fund. Expenses which can not be directly attributed to a fund are generally apportioned based on the relative net assets of each of the funds in the Trust. Expenses of a Fund are borne pro rata by the holders of each class of shares, except that each class bears expenses unique to that class (including the Rule 12b-1 service and distribution fees). In addition, each class votes as a class only with respect to its own Rule 12b-1 Plan. Shares of each class would receive their pro rata share of the net assets of a Fund if the Fund were liquidated. The Trustees approve separate dividends from net investment income on each class of shares.

a. Valuation. Equity securities, including shares of closed-end investment companies and exchange-traded funds, for which market quotations are readily available are valued at market value, as reported by pricing services recommended by the investment adviser and approved by the Board of Trustees. Such pricing services generally use the security’s last sale price on the exchange or market where the security is primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking a NOCP, at the most recent bid quotation on the applicable NASDAQ Market. Debt securities (other than short-term obligations purchased with an original or remaining maturity of sixty days or less) are generally valued on the basis of evaluated bids furnished to the Funds by a pricing service recommended by the investment adviser and approved by the Board of Trustees, which service determines valuations for normal, institutional-size trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders. Broker-dealer bid quotations may also be used to value debt and equity securities where a pricing service does not price a security or where a pricing service does not provide a reliable price for the security. In instances where broker-dealer bid quotations are not available, certain securities held by the Funds may be valued on the basis of a price provided by a principal market maker. Forward foreign currency contracts are valued utilizing interpolated prices determined from information provided by an independent pricing service. Domestic exchange-traded single equity option contracts are valued at the mean of the National Best Bid and offer quotations. Short-term obligations purchased with an original or remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Funds’ investment adviser using consistently applied procedures under the general supervision of the Board of Trustees. Investments in other open-end investment companies are valued at their net asset value each day.

The Funds may hold securities traded in foreign markets. Foreign securities are valued at the market price in the foreign market. However, if events occurring after the close of the foreign market (but before the close of regular trading on the New York Stock Exchange) are believed to materially affect the value of those securities, such securities are fair valued pursuant to procedures approved by the Board of Trustees. When fair valuing securities, the Funds may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Funds calculate their net asset values. As of March 31, 2010, approximately 19% of the market value of the Global Markets Fund’s investments was fair valued pursuant to procedures approved by the Board of Trustees.

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

Net realized foreign exchange gains or losses arise from sales of foreign currency, currency gains or losses realized between the trade and settlement dates on securities transactions and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Funds’ books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities, other than investment securities, at the end of the fiscal period, resulting from changes in exchange rates.

e. Option Contracts. The Funds may enter into option contracts. When a Fund purchases an option, it pays a premium and the option is subsequently marked to market to reflect current value. Premiums paid for purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the cost or deducted from the proceeds on the underlying instrument to determine the realized gain or loss. The risk associated with purchasing options is limited to the premium paid.

When a Fund writes an option, an amount equal to the net premium received (the premium less commission) is recorded as a liability and is subsequently adjusted to the current value until the option expires or the Fund enters into a closing purchase transaction. When a written option expires on its stipulated expiration date or the Fund enters into a closing purchase transaction, the difference between the net premium received and any amount paid at expiration or on effecting a closing purchase transaction, including commission, is treated as a realized gain or, if the net premium received is less than the amount paid, as a realized loss. The Fund, as writer of a written option, bears the risk of an unfavorable change in the market value of the equity underlying the written option.

Exchange-traded options have standardized contracts and are settled through a clearing house with fulfillment guaranteed by the credit of the exchange. Therefore, counterparty credit risks to the Funds are limited. Over-the-counter options are subject to the risk that the counterparty is unable or unwilling to meet its obligations under the option. The Funds are not party to any over-the-counter options at March 31, 2010.

f. Federal and Foreign Income Taxes. The Trust treats each fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2010 and has concluded that no provisions for income tax are required. The Funds’ 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 six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. 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.

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

A Fund may be subject to foreign taxes on income and gains on investments that are accrued based upon the Fund’s understanding of the tax rules and regulations that exist in the countries in which the Fund invests. Foreign governments may also impose taxes or other payments on investments with respect to foreign securities. Such taxes are accrued as applicable, and are reflected as foreign taxes payable on the Statements of Assets and Liabilities. In the event that realized gains on investments are subsequently offset by realized losses, taxes paid on realized gains may be returned to a Fund. Such amounts, if applicable, are reflected as foreign tax rebates receivable on the Statements of Assets and Liabilities.

g. Dividends and Distributions to Shareholders. Dividends and distributions are recorded on ex-dividend date. The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent differences are primarily due to differing treatments for book and tax purposes for items such as net operating losses, distribution redesignations, paydown adjustments, foreign currency transactions, gains realized from passive foreign investment companies (“PFICs”), defaulted bonds and premium amortization accruals. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts. Temporary differences between book and tax distributable earnings are primarily due to deferred Trustees’ fees, forward contracts mark to market, securities lending collateral gain/loss adjustment, straddle loss deferrals, wash sales, premium amortization accruals and defaulted bond interest. Distributions from net investment income and short-term capital gains are considered to be distributed from ordinary income for tax purposes.

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2009:


	2009 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains	Total

Disciplined Equity Fund	$	216,562	—	$	216,562
Global Markets Fund		4,997,799	—		4,997,799
Growth Fund		—	—		—
Mid Cap Growth Fund		—	—		—
Value Fund		6,186,770	—		6,186,770

Differences between these amounts and those reported in the Statements of Changes in Net Assets, if any, are primarily attributable to different book and tax treatment for short-term capital gains.

As of September 30, 2009, the capital loss carryforwards and post-October losses were as follows:


	Disciplined Equity Fund			Global Markets Fund			Growth Fund			Mid Cap Growth Fund			Value Fund

Capital loss carryforward:
Expires September 30, 2010	$	—		$	—		$	(9,606,459	)*	$	(65,130,772	)	$	—

* A significant portion of the Loomis Sayles Growth Fund’s carryforward losses are a result of prior year mergers; therefore, utilization of these losses has been limited under section 382 of the Internal Revenue Code.

h. Repurchase Agreements. It is each 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. Certain 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.

i. Securities Lending. The Funds have entered into an agreement with State Street Bank and Trust Company (“State Street Bank”), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value (including accrued interest) of the loaned international or domestic securities, respectively, when the loan is initiated. Thereafter, the value of the collateral must remain at least 102% of the market value (including accrued interest) of loaned securities for U.S. equities and U.S. corporate debt; at least 105% of the market value (including accrued interest) of loaned

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

securities for non-U.S. equities; and at least 100% of the market value (including accrued interest) of loaned securities for U.S. Government securities, sovereign debt issued by non-U.S. Governments and non-U.S. corporate debt. In the event that the market value of the collateral falls below the required percentages described above, the borrower will deliver additional collateral on the next business day. As with other extensions of credit, the Funds bear the risk of loss with respect to the investment of the collateral. The Funds invest cash collateral in short-term investments, a portion of the income from which is remitted to the borrowers and the remainder allocated between the Funds and State Street Bank as lending agent.

As of March 31, 2010, there were no securities on loan.

j. 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 Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ 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 Funds expect the risk of loss to be remote.

•

Level 1 — quoted prices in active markets for identical assets or liabilities;

•

Level 2 — prices determined using other significant inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar assets or liabilities, 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 asset or liability (unobservable inputs reflect each Fund’s own assumptions in determining the fair value of assets or liabilities 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 Funds are subject to the risk that changes in foreign currency exchange rates will have an unfavorable effect on the value of Fund assets denominated in foreign currencies. The Funds may enter into forward foreign currency contracts for hedging purposes to protect the value of the Funds’ holdings of foreign securities. The Funds may also use forward foreign currency contracts to gain exposure to foreign currencies, regardless of whether securities denominated in such currencies are held in the Funds. During the six months ended March 31, 2010, Global Markets Fund engaged in forward foreign currency transactions to gain exposure to foreign currencies.

Disciplined Equity Fund, Global Markets Fund and Mid Cap Growth Fund are parties to agreements with counterparties that govern transactions in forward foreign currency contracts. These agreements contain contingent features that allow the counterparties to terminate open contracts early if the net asset value of a Fund declines beyond a certain threshold. If such contingent features were to be triggered, the counterparties could request immediate settlement of open contracts at current fair value.

The Funds are subject to the risk of unpredictable declines in the value of individual equity securities and periods of below-average performance in individual securities or in the equity market as a whole. Certain Funds may use purchased put options and written call options to hedge against a decline in value of an equity security that it owns. Certain Funds may also write put options to offset the cost of options used for hedging purposes. During the six months ended March 31, 2010, Disciplined Equity Fund and Mid Cap Growth Fund engaged in written call option transactions. During this same period, Mid Cap Growth Fund also engaged in purchased and written put option transactions.

6. Management Fees and Other Transactions with Affiliates.

a. Management Fees. Loomis, Sayles & Company, L.P. (“Loomis Sayles”) serves as investment adviser to each Fund. Separate management agreements for each Fund in effect for the six months ended March 31, 2010, provided for fees at the following annual percentage rates of each Fund’s average daily net assets:


Fund		Percentage of Average Daily Net Assets
Disciplined Equity Fund		0.50%
Global Markets Fund		0.75%
Growth Fund		0.50%
Mid Cap Growth Fund		0.75%
Value Fund		0.50%

Loomis Sayles has given binding undertakings to the Funds to reduce management fees and/or reimburse certain expenses to limit the Funds’ operating expenses, exclusive of acquired fund fees and expenses, brokerage expenses, interest expense, taxes and extraordinary expenses. These undertakings are in effect until January 31, 2011 and will be reevaluated on an annual basis. Management fee payables, as reflected on the Statement of Assets and Liabilities, are net of fee reductions and/or expense reimbursements, if any, pursuant to these undertakings.

For the period from February 1, 2010 to March 31, 2010, the expense limits as a percentage of average daily net assets under the expense limitation agreements were as follows:


	Expense Limit as a Percentage of Average Daily Net Assets
Fund	Class A		Class B		Class C		Class Y		Admin Class
Disciplined Equity Fund	1.25	%	2.00	%	2.00	%	1.00	%	N/A

Loomis Sayles shall be permitted to recover expenses it has borne under the expense limitation agreements (whether through reduction of its management fees or otherwise) on a class by class basis in later periods to the extent a class’ expenses fall below a class’ expense limits, 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 fees/expenses were reduced. Fees waived and/or expenses reimbursed pursuant to the voluntary agreement cannot be recovered by Loomis Sayles in later periods.

Pursuant to an agreement among Natixis Funds Trust I, Natixis Funds Trust II, Natixis Funds Trust IV, Natixis Cash Management Trust, Gateway Trust (“Natixis Funds Trusts”), Loomis Sayles Funds I, Loomis Sayles Funds II (“Loomis Sayles Funds Trusts”), Hansberger International Series and Natixis Advisors, each 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 additional class and an additional $75,000 if managed by multiple subadvisers.

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

Under the Admin Class Plan, the Value Fund pays Natixis Distributors a monthly distribution fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Fund’s Admin Class shares, as compensation for services provided by Natixis Distributors in connection with the marketing or sale of Admin Class shares or for payments made by Natixis Distributors to securities dealers or other financial intermediaries as commissions, asset-based sales charges or other compensation with respect to the sale of Admin Class shares, or for providing personal services to investors and/or the maintenance of shareholder accounts.

In addition, the Admin Class shares of the Value Fund may pay Natixis Distributors an administrative service fee, at an annual rate not to exceed 0.25% of the average daily net assets attributable to Admin Class shares. These fees are subsequently paid to securities dealers or financial intermediaries for providing personal services and/or account maintenance for their customers who hold such shares.

For the six months ended March 31, 2010 the Fund paid the following service and distribution fees:


	Service Fees									Distribution Fees
	Class A		Class B		Class C		Admin Class			Class B		Class C		Admin Class

(a) Amount is less than $1.

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 Funds if the shares of those customers were registered directly with the Funds’ transfer agent. Accordingly, the Funds agreed to pay a portion of the intermediary fees attributable to shares of the Fund held by the intermediaries (which generally is a percentage of the value of shares held) not exceeding what the Funds 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.

For the six months ended March 31, 2010, the Funds paid the following sub-transfer agent fees, which are reflected in transfer agent fees and expenses in the Statements of Operations.


Fund	Sub-Transfer Agent Fees
Disciplined Equity Fund	$	10,043
Global Markets Fund		98,519
Growth Fund		39,348
Mid Cap Growth Fund		59,101
Value Fund		288,877

e. Commissions. The Funds have been informed that commissions (including CDSCs) on Fund shares retained by Natixis Distributors during the six months ended March 31, 2010, were as follows:


Fund	Commissions
Disciplined Equity Fund	$	2,460
Global Markets Fund		117,446
Growth Fund		19,274
Mid Cap Growth Fund		1,846
Value Fund		24,328

f. Trustees Fees and Expenses. The Funds do 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. Effective January 1, 2010, the Chairperson of the Board receives a retainer fee at the annual rate of $250,000. 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 $80,000. Each Independent Trustee also receives a meeting attendance fee of $10,000 for each meeting of the Board of Trustees that he or she attends in person and $5,000 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 $15,000. Each Contract Review and Governance Committee member is compensated $6,000 for each Committee meeting that he or she attends in person and $3,000 for each meeting that he or she attends telephonically. Each Audit Committee member is compensated $7,500 for each Committee meeting that he or she attends in person and $3,750 for each meeting that he or she attends telephonically. Each member of the ad hoc Committee on Alternative Investments received a one-time fee of $10,000. The ad hoc Committee on Alternative Investments is not a standing committee. 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.

7. Line of Credit. Each 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 committed unsecured 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, plus 1.25%. In addition, a commitment fee of 0.15% 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.

For the six months ended March 31, 2010, the Funds had no borrowings under these agreements.

8. Concentration of Risk. Each Fund may purchase investments of foreign issuers. Investing in securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies and securities of the U.S. Government. These risks include revaluation of currencies and the risk of expropriation. Moreover, the markets for securities of many foreign issuers may be less liquid and the prices of such securities may be more volatile than those of comparable U.S. companies and the U.S. Government.

Investment activities of these shareholders could have material impacts on the Funds. As of March 31, 2010, certain Funds had shareholders that held greater than 5% of the fund’s outstanding shares. Such ownership may be beneficially held by individuals or entities other than the owner of record.

PORTFOLIO REVIEW

After finishing 2009 on a strong note, the stock market started off slowly in 2010, with investors digesting the extraordinary gains of the previous year while wondering whether signs of improved economic activity were sustainable. March data revealed a brighter employment picture, increased manufacturing activity and greater stability in housing—and the market responded accordingly. Strong fourth-quarter returns, combined with solid gains in March, led to solid six-month returns for all segments of the stock market.

For the six months ended March 31, 2010, Institutional Class shares of Loomis Sayles Small Cap Growth Fund returned 15.37%. The fund outperformed its benchmark, the Russell 2000 Growth Index, which returned 12.07% for the period.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

The fund’s outperformance was due primarily to a shift in investor focus to the type of companies we favor, particularly during the fourth quarter of 2009: companies with strong competitive positions that can sustain growth well into the future. Additionally, the fund’s performance benefited from strong stock selection across a diverse group of sectors, including healthcare, consumer discretionary, producer durables and energy.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

Our healthcare holdings were the greatest contributors to performance. Leading stocks included Incyte, a biotechnology company, which signed large partnerships for two of its drugs, and SXC Health Solutions, a pharmacy benefit management services and healthcare IT company, which reported strong fourth-quarter results. Our position in IMAX, the leader in 3-D movies, led performance in the consumer discretionary sector, while Bucyrus International, an industrial, construction and mining company, reported better-than-expected earnings and drove results in producer durables.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Stock selection in the technology, materials and utilities sectors had a negative impact on the fund’s relative performance. Brocade, a provider of switching solutions for storage area networks, was among the largest detractors, after missing earnings estimates and issuing lower-than-expected guidance. We reduced the fund’s technology weight, primarily due to weak prospects for growth among specific communication equipment and software companies. Nevertheless, technology remains the fund’s largest sector weight.

Data quoted reflects past performance and cannot guarantee future results. Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit www.loomissayles.com. Current performance may be higher or lower than quoted.

Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Periods of less than one year are not annualized. Performance data reflects certain fee reductions and reimbursements, if any, without which performance would be lower.

(a) Cumulative performance is shown for the institutional class of shares. Performance of the retail class would be lower due to higher fees. (b) The mountain chart is based on the initial investment minimum of $100,000 for the institutional class. (c) See page 5 for a description of the indices.

WHAT YOU SHOULD KNOW

The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. The fund is subject to currency risk, which is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of a fund’s investments to decline. Fund shares should be viewed as a long-term investment.

PORTFOLIO REVIEW

After finishing 2009 on a strong note, the stock market started off slowly in 2010, as investors digested the extraordinary gains of the previous year while wondering whether improved economic activity was sustainable. March data revealed a brighter employment picture, increased manufacturing activity and greater stability in housing—and the market responded accordingly. Strong fourth-quarter returns, combined with solid gains in March, led to solid six-month returns for all segments of the stock market.

For the six months ended March 31, 2010, Institutional Class shares of Loomis Sayles Small Cap Value Fund returned 9.74%. The fund underperformed its benchmark, the Russell 2000 Value Index, which returned 14.01% for the period.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S UNDERPERFORMANCE?

The fund underperformed its benchmark because of its focus on higher-quality stocks, which underperformed lower-quality stocks during the first quarter of 2010. In general, the small-cap market was led by low-priced stocks, the smallest market caps and low-quality companies.

WHICH FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

In 2009, we made several additions to the portfolio early in the market recovery, emphasizing smaller-cap and more cyclical stocks poised for a recovery. These changes helped limit the negative impact of the low-quality rally in 2009. However, we backed off the strategy late last year and early in 2010, as better fundamentals emerged. Hence, we were surprised that low-quality stocks, a segment of the market that typically does not match up well with our strategy, continued to lead the market in 2010. Stock selection in the healthcare sector contributed positively. Perrigo, a store-brand over-the-counter pharmaceutical provider, was one of the fund’s top performers.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Stock selection was negative during the period, with the financial services, materials and processing and technology sectors detracting the most. In particular, our holdings among high-quality banks and non-credit-sensitive transaction processors did not keep pace with the index return of the financial services sector overall.

CUMULATIVE PERFORMANCE

Inception to March 31, 2010^(d)(e)

LOGO

(a) Prior to the inception of retail class shares (12/31/96) and admin class shares (1/2/98), performance is that of institutional class shares, restated to reflect the higher net expenses of the retail class shares and admin class shares, respectively. Since index performance data is not available coincident with the fund’s inception date, the beginning value of the index is the value as of the month end closest to the Fund’s inception date. (b) The Lipper Small-Cap Core Funds Index performance data is not available prior to January 1, 1992. (c) See page 5 for a description of the Indices. (d) Cumulative performance is shown for the institutional class of shares. Performance of the retail and admin classes would be lower due to higher fees and expenses. (e) The mountain chart is based on the initial investment minimum of $100,000 for the institutional class.

WHAT YOU SHOULD KNOW

Value stocks may fall out of favor with investors and underperform the overall equity market during any given period. Small- and mid-cap stocks may be more volatile than larger, more established companies. The secondary market for these stocks may be less liquid, which could adversely impact the Fund’s value.

The fund can invest a significant percentage of assets in foreign securities and the value of the fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. The fund is subject to currency risk, which is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of a fund’s investments to decline. Fund shares should be viewed as a long-term investment.

Quarterly Portfolio Schedules

UNDERSTANDING YOUR FUND’S EXPENSES

As a mutual fund shareholder you incur two types of costs: (1) transaction costs, including redemption fees and certain exchange fees; and (2) ongoing costs, including management fees, distribution and/or service fees (12b-1 fees), and other fund expenses. These costs are described in more detail in the funds’ prospectus. The examples below are intended to help you understand the ongoing costs of investing in the Funds and help you compare these with the ongoing costs of investing in other mutual funds.

The first line in the table of each fund shows the actual amount of fund expenses you would have paid on a $1,000 investment in the fund from October 1, 2009 through March 31, 2010. 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 column as shown below for your class.

The second line in the table of each fund 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 funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of 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.

NOTES TO FINANCIAL STATEMENTS

March 31, 2010 (Unaudited)

1. Organization. Loomis Sayles Funds I and Loomis Sayles Funds II (the “Trusts” and each a “Trust”) are each organized as a Massachusetts business trust. Each Trust is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. Each Declaration of Trust permits the Board of Trustees to authorize the issuance of an unlimited number of shares of the Trusts in multiple series. The financial statements for certain funds of the Trusts are presented in separate reports. The following funds (individually, a “Fund” and collectively, the “Funds”) are included in this report:

Loomis Sayles Funds I:

Loomis Sayles Small Cap Value Fund (the “Small Cap Value Fund”)

Loomis Sayles Funds II:

Loomis Sayles Small Cap Growth Fund (the “Small Cap Growth Fund”)

Each Fund offers Institutional Class Shares and Retail Class Shares. In addition, Small Cap Value Fund offers Admin Class Shares.

Most expenses of the Trusts can be directly attributed to a fund. Expenses which cannot be directly attributed to a fund are generally apportioned based on the relative net assets of each of the funds in the Trusts. Expenses of a Fund are borne pro rata by the holders of each class of shares, except that each class bears expenses unique to that class (including the Rule 12b-1 service and distribution fees and transfer agent fees). In addition, each class votes as a class only with respect to its own Rule 12b-1 Plan. Shares of each class would receive their pro rata share of the net assets of a 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 each Fund in the preparation of its financial statements. The Funds’ 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 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. Equity securities, including shares of closed-end investment companies and exchange-traded funds, for which market quotations are readily available are valued at market value, as reported by pricing services recommended by the investment adviser and approved by the Board of Trustees. Such pricing services generally use the security’s last sale price on the exchange or market where the security is primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking a NOCP, at the most recent bid quotation on the applicable NASDAQ Market. Debt securities (other than short-term obligations purchased with an original or remaining maturity of sixty days or less) are generally valued on the basis of evaluated bids furnished to the Funds by a pricing service recommended by the investment adviser and approved by the Board of Trustees, which service determines valuations for normal, institutional-size trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders. Broker-dealer bid quotations may also be used to value debt and equity securities where a pricing service does not price a security or where a pricing service does not provide a reliable price for the security. In instances where broker-dealer bid quotations are not available, certain securities held by the Funds may be valued on the basis of a price provided by a principal market maker. Forward foreign currency contracts are valued utilizing interpolated prices determined from information provided by an independent pricing service. Short-term obligations purchased with an original or remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Funds’ investment adviser using consistently applied procedures under the general supervision of the Board of Trustees. Investments in other open-end investment companies are valued at their net asset value each day.

b. Security Transactions and Related Investment Income. Security transactions are accounted for on trade date. Dividend income is recorded on ex-dividend date, or in the case of certain foreign securities, as soon as a Fund is notified, 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. Distributions received from investments in securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments or as a realized gain, respectively. The calendar year-end amounts of ordinary income, capital gains, and return of capital included in distributions received from the Funds’ investments in real estate investment trusts (“REITs”) are reported to the Funds after the end of the fiscal year; accordingly, the Funds estimate these amounts for accounting purposes until the characterization of REIT distributions is reported to the Funds after the end of the fiscal year. Estimates are based on the most recent REIT distribution information available. Investment income is recorded net of foreign taxes withheld when applicable. In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. Investment income, non-class specific expenses and realized and unrealized gains and losses are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund.

Net realized foreign exchange gains or losses arise from sales of foreign currency, currency gains or losses realized between the trade and settlement dates on securities transactions and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Funds’ books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities, other than investment securities, at the end of the fiscal period, resulting from changes in exchange rates.

d. Federal and Foreign Income Taxes. Each Trust treats each fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2010 and has concluded that no provisions for income tax are required. The Funds’ 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 six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. 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 are recorded on ex-dividend date. The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent differences are primarily due to differing treatments for book and tax purposes for items such as distribution redesignation and net operating losses. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts. Temporary differences between book and tax distributable earnings are primarily due to securities lending collateral gain/loss adjustment, deferred Trustees’ fees and wash sales. Distributions from net investment income and short-term capital gains are considered to be distributed from ordinary income for tax purposes.

NOTES TO FINANCIAL STATEMENTS – continued

March 31, 2010 (Unaudited)

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2009 was as follows:


	2009 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Small Cap Growth Fund	$	—	$	—	$	—
Small Cap Value Fund		3,669,309		331,178		4,000,487

Differences between these amounts and those reported in the Statements of Changes in Net Assets, if any, are primarily attributable to different book and tax treatment for short-term capital gains.

As of September 30, 2009, the capital loss carryforwards and post-October losses were as follows:


	Small Cap Growth Fund			Small Cap Value Fund
Capital loss carryforward:
Expires September 30, 2010	$	(138,314,515	)	$	—
Expires September 30, 2011		(59,283,040	)		—
Expires September 30, 2017		(14,995,800	)		(88,137,321	)

Total capital loss carryforward	$	(212,593,355	)	$	(88,137,321	)

Deferred net capital losses (post-October 2008)	$	(26,616,006	)	$	(110,445,559	)

f. Repurchase Agreements. It is each 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. Certain 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.

g. Securities Lending. The Funds have entered into an agreement with State Street Bank and Trust Company (“State Street Bank”), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value (including accrued interest) of the loaned international or domestic securities, respectively, when the loan is initiated. Thereafter, the value of the collateral must remain at least 102% of the market value (including accrued interest) of loaned securities for U.S. equities and U.S. corporate debt; at least 105% of the market value (including accrued interest) of loaned securities for non-U.S. equities; and at least 100% of the market value (including accrued interest) of loaned securities for U.S. Government securities, sovereign debt issued by non-U.S. Governments and non-U.S. corporate debt. In the event that the market value of the collateral falls below the required percentages described above, the borrower will deliver additional collateral on the next business day. As with other extensions of credit, the Funds bear the risk of loss with respect to the investment of the collateral. The Funds invest cash collateral in short-term investments, a portion of the income from which is remitted to the borrowers and the remainder allocated between the Funds and State Street Bank as lending agent.

As of March 31, 2010, there were no securities on loan.

h. Indemnifications. Under the Trusts’ organizational documents, their officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ 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 Funds expect the risk of loss to be remote.

3. Fair Value Measurements. In accordance with accounting standards related to fair value measurements and disclosures, the Funds have categorized the inputs utilized in determining the value of each Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

•

Level 1—quoted prices in active markets for identical assets or liabilities;

•

Level 2—prices determined using other significant inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar assets or liabilities, 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 asset or liability (unobservable inputs reflect each Fund’s own assumptions in determining the fair value of assets or liabilities 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 Funds’ investments as of March 31, 2010, at value:

Fund	Administrative Fees
Small Cap Growth Fund	$	30,217
Small Cap Value Fund		232,150

Pursuant to Rule 12b-1 under the 1940 Act, the Small Cap Growth Fund and Small Cap Value Fund have adopted a Distribution Plan relating to each Fund’s Retail Class shares (the “Retail Class Plan”), and the Small Cap Value Fund has adopted a Distribution Plan relating to its Admin Class shares (the “Admin Class Plan”).

Under the respective Retail Class Plan, each Fund pays Natixis Distributors a monthly distribution fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Funds’ Retail Class shares, as compensation for services provided by Natixis Distributors in connection with the marketing or sale of Retail Class shares or for payments made by Natixis Distributors to securities dealers or other financial intermediaries as commissions, asset-based sales charges or other compensation with respect to the sale of Retail Class shares, or for providing personal services to investors and/or the maintenance of shareholder accounts.

Under the Admin Class Plan, the Small Cap Value Fund pays Natixis Distributors a monthly distribution fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Fund’s Admin Class shares, as compensation for services provided by Natixis Distributors in connection with the marketing or sale of Admin Class shares or for payments made by Natixis Distributors to securities dealers or other financial intermediaries as commissions, asset-based sales charges or other compensation with respect to the sale of Admin Class shares, or for providing personal services to investors and/or the maintenance of shareholder accounts.

In addition, the Admin Class shares of the Small Cap Value may pay Natixis Distributors an administrative service fee, at an annual rate not to exceed 0.25% of the average daily net assets attributable to Admin Class shares. These fees are subsequently paid to securities dealers or financial intermediaries for providing personal services and/or account maintenance for their customers who hold such shares.

For the six months ended March 31, 2010 the Fund paid the following service and distribution fees:


	Service Fees		Distribution Fees
	Admin Class		Retail Class		Admin Class
Small Cap Growth Fund	$	—	$	99,753	$	—

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 Funds if the shares of those customers were registered directly with the Funds’ transfer agent. Accordingly, the Funds agreed to pay a portion of the intermediary fees attributable to shares of the Fund held by the intermediaries (which generally is a percentage of the value of shares held) not exceeding what the Funds 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.

For the six months ended March 31, 2010, the Funds paid the following sub-transfer agent fees, which are reflected in transfer agent fees and expenses in the Statements of Operations:


	Sub-Transfer Agent Fees
Fund	Institutional Class		Retail Class		Admin Class
Small Cap Growth Fund	$	16,330	$	21,614	$	—
Small Cap Value Fund		183,310		259,468		83,929

e. Trustees Fees and Expenses. The Funds do not pay any compensation directly to their officers or Trustees who are directors, officers or employees of Natixis Advisors, Natixis Distributors, Natixis US or their affiliates. Effective January 1, 2010, the Chairperson of the Board receives a retainer fee at the annual rate of $250,000. 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 $80,000.

What You Should Know:

This fund invests in fixed-income securities that are subject to credit risk, interest rate risk and liquidity risk. It may also invest in mortgage-related securities that are subject to prepayment risk. The fund can invest a significant percentage of assets in foreign securities and the value of fund shares can be adversely affected by changes in currency exchange rates, political, and economic developments. In emerging markets these risks can be significant. The fund is subject to currency risk, which is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of a fund’s investments to decline. Lower rated debt securities have speculative characteristics and may be subject to greater price volatility than higher rated investments. In addition, the secondary market for these securities may lack liquidity. Fund shares should be viewed as a long-term investment.

Management Discussion

Corporate debt and other fixed-income securities offering yield advantages over low-risk bonds continued to perform well during the six months ended March 31, 2010. Amid growing market expectations of a sustained global economic recovery, investors became more willing to accept credit risk in return for the high yields offered by corporate bonds and securitized debt. In line with the increasing appetite for risk, currencies of countries with commodity-based economies gained against other countries.

For the six months ended March 31, 2010, Class A shares of Loomis Sayles Investment Grade Bond Fund returned 6.24%. During the same period, the fund’s benchmark, the Barclays Capital U.S. Government/Credit Bond Index, rose 1.34%, while funds in Morningstar’s Intermediate-Term Bond category returned an average of 3.70%.

WHAT WAS THE PRIMARY REASON FOR THE FUND’S OUTPERFORMANCE?

As investors grew more confident about an economic recovery, securities with credit risk tended to rally in price. The fund’s emphasis on investment-grade corporate bonds, as well as its exposure to high-yield bonds and select non-agency securitized assets, helped propel strong results relative to the Barclays index. Moreover, as commodities gained in price in global markets, the fund’s exposure to commodity-linked currencies also helped support performance. The fund’s investments in securities denominated in the currencies of Canada, Indonesia, Australia, New Zealand and Mexico all contributed positive returns. Convertible bonds were also a performance driver.

WHAT FACTORS POSITIVELY CONTRIBUTED TO THE FUND’S PERFORMANCE?

Investment-grade industrial bonds were among the strongest performers, particularly holdings in the transportation, technology, capital goods and telecommunication services industries. In addition, investments in higher-yielding, below investment-grade corporate bonds also aided results, as demand for high-yield securities increased and expected default rates fell. In particular, positions in high-yield bonds of companies in the transportation, technology, retail and financial industries contributed positively to results. Investments in non-government agency securitized debt, including commercial mortgage-backed debt, provided further support. Finally, the dramatic performance of equity markets during the six months covered by this report also aided the fund, as convertible bonds rallied in industries such as autos, technology and financials.

WHICH FACTORS DETRACTED FROM THE FUND’S RESULTS?

Holdings in securities denominated in Icelandic krona underperformed when the currency depreciated relative to the U.S. dollar. In addition, the fund’s longer-than-benchmark duration – a measure of sensitivity to changes in interest rates – was a performance detractor as interest-rate sensitive longer-maturity bonds lagged.

WHAT IS YOUR CURRENT OUTLOOK?

The fund is positioned to take advantage of a gradual economic recovery and positive fundamental trends. We believe short-term interest rates in the United States will remain low for the foreseeable future, but acknowledge the continuing pressures that the ever-increasing U.S. Treasury issuance will place on longer-term rates. In our opinion, there remains ample opportunity for corporate bond yield spreads to tighten further. Within corporate credit, we are advocating a strategy of specific (fundamental credit) risk instead of market (interest rate) risk. We continue to see opportunity in the convertible market and have focused on increasing our exposure. We continue to add opportunistically to non-U.S. dollar-denominated securities, with a focus on credits and countries in which we anticipate fundamental improvements will continue to emerge. We believe that in a rising-rate environment, research and security selection will continue to prove key to successful portfolio management.

PERFORMANCE IN PERSPECTIVE

The charts comparing the fund’s performance to an index provide you with a general sense of how it performed. The fund’s total return for the period shown below appears with and without sales charges and includes fund expenses and fees. An index measures the performance of a theoretical portfolio. Unlike a fund, the index is unmanaged and does not have expenses that affect the results. It is not possible to invest directly in an index. Investors would incur transaction costs and other expenses if they purchased the securities necessary to match the index.

UNDERSTANDING YOUR FUND’S EXPENSES

As a mutual fund shareholder, you incur different types of costs: transaction costs, including sales charges (loads) on purchases and contingent deferred sales charges on redemptions; certain exchange fees; and ongoing costs, including management fees, distribution fees (12b-1 fees) and/or service fees, and other fund expenses. In addition, the fund may assess 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 amount of fund expenses you would have paid on a $1,000 investment in the fund from October 1, 2009 through March 31, 2010. 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 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 of the fund 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.

NOTESTO FINANCIAL STATEMENTS

March 31, 2010 (Unaudited)

1. Organization. Loomis Sayles Funds II (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 Board of Trustees to authorize the issuance of an unlimited number of shares of the Trust in multiple series. The financial statements for certain funds of the Trust are presented in separate reports. Information presented in these financial statements pertains to Loomis Sayles Investment Grade Bond Fund (the “Fund” or the “Investment Grade Bond Fund”).

The Fund offers Class A, Class C, Class Y, Admin Class and Class J. Effective February 1, 2010, the Fund began offering Admin Class 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 Fund’s Prospectus.

Class A shares are sold with a maximum front-end sales charge of 4.50%. Class B shares do not pay a front-end sales charge, but pay higher Rule 12b-1 fees than Class A shares for eight years (at which point they automatically convert to Class A shares) and are subject to a contingent deferred sales charge (“CDSC”) if those shares are redeemed within six years of purchase. Class C shares do not pay a front-end sales charge, do not convert to any other class of shares, pay higher Rule 12b-1 fees than Class A shares and may be subject to a CDSC of 1.00% if those shares are redeemed within one year of acquisition except for reinvested distributions. Class Y shares do not pay a front-end sales charge, a CDSC or Rule 12b-1 fees. Class Y shares are generally intended for institutional investors with a minimum initial investment of $100,000, though some categories of investors are exempted from the minimum investment amount as outlined in the Fund’s Prospectus. Admin Class shares do not pay a front-end sales charge or a CDSC, but do pay a Rule 12b-1 fee. Admin Class shares are offered exclusively through intermediaries. Class J shares are only offered to non-U.S. investors and are sold with a maximum front-end sales charge of 3.50%.

Most expenses of the Trust can be directly attributed to a fund. Expenses which can not be directly attributed to a fund are generally apportioned based on the relative net assets of each of the funds in the Trust. 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 (including the Rule 12b-1 service and distribution fees, registration, legal, shareholder reporting and Class J transfer agent fees). In addition, each class votes as a class only with respect to its own Rule 12b-1 Plan. 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 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.

The Fund may hold securities traded in foreign markets. Foreign securities are valued at the market price in the foreign market. However, if events occurring after the close of the foreign market (but before the close of regular trading on the New York Stock Exchange) are believed to materially affect the value of those securities, such securities are fair valued pursuant to procedures approved by the Board of Trustees. When fair valuing securities, the Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Fund calculates its net asset value.

b. Security Transactions and Related Investment Income. Security transactions are accounted for on trade date. Interest income is recorded on an accrual basis. Interest income is increased by the accretion of discount and decreased by the amortization of premium. Investment income is recorded net of foreign taxes withheld when applicable. In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. Investment income, non-class specific expenses and realized and unrealized gains and losses are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund.

c. Foreign Currency Translation. The books and records of the Fund are maintained in U.S. dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the period. Purchases and sales of investment securities, income and expenses are translated on the respective dates of such transactions.

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

Net realized foreign exchange gains or losses arise from sales of foreign currency, currency gains or losses realized between the trade and settlement dates on securities transactions and the difference between the amounts of interest and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities, other than investment securities, at the end of the fiscal period, resulting from changes in exchange rates.

The Fund may use foreign currency exchange contracts to facilitate transactions in foreign-denominated investments. Losses may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.

d. Forward Foreign Currency Contracts. The Fund may enter into forward foreign currency contracts. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell generally are used to hedge the Fund’s investments against currency fluctuation. Also, a contract to buy or sell can offset a previous contract. These contracts involve market risk in excess of the unrealized gain or loss reflected in the Fund’s Statement of Assets and Liabilities. The U.S. dollar value of the currencies the Fund has committed to buy or sell represents the aggregate exposure to each currency the Fund has acquired or hedged through currency contracts outstanding at period end. Gains or losses are recorded for financial statement purposes as unrealized until settlement date. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. Certain contracts may require the movement of cash or securities to or from the counterparty as collateral for the Fund’s or counterparty’s net obligations under the contracts.

At March 31, 2010, there were no open forward foreign currency contracts.

e. Federal and Foreign Income Taxes. The Trust treats each fund as a separate entity for federal income tax purposes. The Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of the Fund’s tax positions for the open tax years as of March 31, 2010 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 six 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.

The Fund may be subject to foreign taxes on income and gains on investments that are accrued based upon the Fund’s understanding of the tax rules and regulations that exist in the countries in which the Fund invests. Foreign governments may also impose taxes or other payments on investments with respect to foreign securities. Such taxes are accrued as applicable, and are reflected as foreign taxes payable on the Statement of Assets and Liabilities.

f. Dividends and Distributions to Shareholders. Dividends and distributions are recorded on ex-dividend date. The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent differences are primarily due to differing treatments for book and tax purposes for items such as defaulted bonds, distribution redesignations, foreign currency transactions, paydown adjustments and premium amortization accruals. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts. Temporary differences between book and tax distributable earnings are primarily due to premium amortization accruals, deferred Trustees’ fees, defaulted bond accruals, securities lending collateral gain/loss adjustments and wash sales. Distributions from net investment income and short-term capital gains are considered to be distributed from ordinary income for tax purposes.

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2009 was as follows:


2009 Distributions Paid From:
Ordinary Income	Long-Term Capital Gains		Total
$386,232,314	$	9,171,073	$	395,403,387

Differences between these amounts and those reported in the Statement of Changes in Net Assets, if any, are primarily attributable to different book and tax treatment for short-term capital gains.

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

As of September 30, 2009, the capital loss carryforwards and post-October losses were as follows:


Capital loss carryforward:
Expires September 30, 2017	$	(1,891,321	)

Deferred net capital losses (post- October 2008)	$	(3,774,568	)

g. 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. Certain 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.

h. Securities Lending. The Fund has entered into an agreement with State Street Bank and Trust Company (“State Street Bank”), as agent of the Fund, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value (including accrued interest) of the loaned international or domestic securities, respectively, when the loan is initiated. Thereafter, the value of the collateral must remain at least 102% of the market value (including accrued interest) of loaned securities for U.S. equities and U.S. corporate debt; at least 105% of the market value (including accrued interest) of loaned securities for non-U.S. equities; and at least 100% of the market value (including accrued interest) of loaned securities for U.S. Government securities, sovereign debt issued by non-U.S. Governments and non-U.S. corporate debt. In the event that the market value of the collateral falls below the required percentages described above, the borrower will deliver additional collateral on the next business day. As with other extensions of credit, the Fund bears the risk of loss with respect to the investment of the collateral. The Fund invests cash collateral in short-term investments, a portion of the income from which is remitted to the borrowers and the remainder allocated between the Fund and State Street Bank as lending agent.

As of March 31, 2010 there were no securities on loan.

i. 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. In accordance with accounting standards related to fair value measurements and disclosures, the Fund has categorized the inputs utilized in determining the value of the Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

•

Level 1 – quoted prices in active markets for identical assets or liabilities;

•

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 asset or liability (unobservable inputs reflect the Fund’s own assumptions in determining the fair value of assets or liabilities 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.

Purchases and sales of U.S. Government/agency securities (excluding short-term investments and including paydowns) were $91,234,632 and $238,966,372, respectively.

5. Management Fees and Other Transactions with Affiliates.

a. Management Fees. Loomis, Sayles & Company, L.P. (“Loomis Sayles”) serves as investment adviser to the Fund. Under the terms of the management agreement, the Fund pays a management fee at the annual rate of 0.40% of average daily net assets, calculated daily and payable monthly.

NOTESTO FINANCIAL STATEMENTS (continued)

March 31, 2010 (Unaudited)

Loomis Sayles has given a binding undertaking to the Fund to reduce management fees and/or reimburse certain expenses to limit the Fund’s operating expenses, exclusive of acquired fund fees and expenses, brokerage expenses, interest expense, taxes and extraordinary expenses. This undertaking is in effect until January 31, 2011 and will be reevaluated on an annual basis. Management fee payable, as reflected on the Statement of Assets and Liabilities, is net of fee reductions and/or expense reimbursements, if any, pursuant to these undertakings.

For the period from February 1, 2010 to March 31, 2010, the expense limits as a percentage of average daily net assets under the expense limitation agreement were as follows:


Expense Limit as a Percentage of Average Daily Net Assets
Class A	Class B	Class C	Class Y	Admin Class	Class J
0.95%	1.70%	1.70%	0.70%	1.20%	1.30%

Prior to February 1, 2010, the expense limit as a percentage of average daily net assets for Class Y was 0.55%.

Loomis Sayles shall be permitted to recover expenses it has borne under the expense limitation agreement (whether through reduction of its management fees or otherwise) on a class by class basis in later periods to the extent the expenses of a class fall below a class’ expense limits, 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 fees/expenses were reduced.

For the six months ended March 31, 2010, the management fees for the Fund were $18,751,238 (0.40% of average daily net assets).

For the six months ended March 31, 2010, class-specific expenses have been reimbursed as follows:


Reimbursement¹
Class A	Class B		Class C		Class Y		Admin Class		Class J
$—	$	—	$	—	$	26,680	$	5,110	$	4,035

¹	Expense reimbursements are subject to possible recovery until September 30, 2011.

No expenses were recovered during the six months ended March 31, 2010 under the terms of the expense limitation agreement.

b. Administrative Fees. Natixis Asset Management Advisors, L.P.

March 31, 2010 (Unaudited)

Under the respective Class B and Class C Plans, the Fund pays Natixis Distributors a monthly service fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Fund’s Class B and Class C shares, as compensation for services provided by Natixis Distributors in providing personal services to investors in Class B and Class C shares and/or the maintenance of shareholder accounts.

Also under the respective Class B and Class C Plans, the Fund pays Natixis Distributors a monthly distribution fee at the annual rate of 0.75% of the average daily net assets attributable to the Fund’s Class B and Class C shares, as compensation for services provided by Natixis Distributors in connection with the marketing or sale of Class B and Class C shares.

Under the Admin Class Plan, the Fund pays Natixis Distributors a monthly distribution fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Fund’s Admin Class shares, as compensation for services provided by Natixis Distributors in connection with the marketing or sale of Admin Class shares or for payments made by Natixis Distributors to securities dealers or other financial intermediaries as commissions, asset-based sales charges or other compensation with respect to the sale of Admin Class shares, or for providing personal services to investors and/or the maintenance of shareholder accounts.

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 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.

For the six months ended March 31, 2010, the Fund paid the following sub-transfer agent fees which are reflected in transfer agent fees and expenses in the Statement of Operations.


Sub Transfer Agent Fees

funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts and 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 Funds 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 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 normally reflected as Trustees’ fees and expenses in the Statement of Operations. The portions of the accrued obligations allocated to the Fund under the Plan are reflected as Deferred Trustees’ fees on the Statement of Assets and Liabilities.

6. Class-Specific Expenses. For the six months ended March 31, 2010, the Fund paid the following class-specific expenses:


	Class A		Class B		Class C		Class Y		Admin Class		Class J
Transfer Agent Fees and Expenses	$	1,180,701	$	6,890	$	1,002,771	$	1,464,116	$	—	$	4,507

7. 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 committed unsecured 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, plus 1.25%. In addition, a commitment fee of 0.15% 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 10, 2010, 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 committed unsecured 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 greater of the Federal Funds rate or overnight LIBOR, plus 0.75%. In addition, a commitment fee of 0.125% 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 six months ended March 31, 2010, the Fund had no borrowings under these agreements.

8. Concentration of Risk. The Fund may purchase investments of foreign issuers. Investing in securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies and securities of the U.S. Government. These risks include revaluation of currencies and the risk of expropriation. Moreover, the markets for securities of many foreign issuers may be less liquid and the prices of such securities may be more volatile than those of comparable U.S. companies and the U.S. Government.

9. Concentration of Ownership. At March 31, 2010, the Loomis Sayles Employees’ Profit Sharing Retirement Plan held 475,869 shares of beneficial interest of Class Y shares.
