LOOMIS SAYLES SMALL CAP GROWTH FUND

Fund and manager review

FUND FACTS

Managers:

Mark F. Burns, CFA

John Slavik, CFA

Symbols:


Institutional Class		LSSIX
Retail Class		LCGRX

Objective:

Long-term capital growth from investments in common stocks or other equity securities

Strategy:

Invests at least 80% of its net assets (plus any borrowings made for investment purposes) in equity securities of companies with market capitalizations that fall within the capitalization range of the Russell 2000 Index or is $3 billion or less at the time of investment. Unlike the Index, the Fund may invest in companies of any size.

The fund may invest any portion of its assets in Canadian securities and up to 20% of assets in other foreign securities, including emerging markets securities.

Fund Inception Date:

December 31, 1996

Net Assets:

$249.5 million

Market Conditions

Stocks rallied sharply during the six-month period, fueled by a modest improvement in U.S. business conditions and renewed investor optimism stemming from continued accommodation from the Federal Reserve Board (the Fed). These factors, combined with better-than-expected corporate profits, drove share prices higher despite political turmoil in North Africa and the Middle East and the earthquake, tsunami and nuclear crisis in Japan. Risk appetites stayed fairly high, and equities remained the vehicle of choice for investors. Overall, small-cap stocks led the market higher, and growth stocks outperformed value stocks.

Performance Results

For the six months ended March 31, 2011, Institutional Class shares of Loomis Sayles Small Cap Growth Fund returned 32.43%. The fund outperformed its benchmark, the Russell 2000 Growth Index, which returned 27.93% for the period.

Explanation of Fund Performance

Strong stock selection primarily drove the fund’s relative outperformance. Our choices were particularly strong in the consumer discretionary sector, where IMAX and Tempur-Pedic International drove results. Shares of IMAX, the operator of large screen movie theaters, rose sharply after beating earnings and raising estimates for new theater installations. Tempur-Pedic shares rose sharply after reporting better-than-expected earnings due to market share gains for the company’s Cloud Collection mattresses, which appeal to the higher end of the market. Stock selection and an overweight position led to favorable relative results in the energy sector with Rosetta Resources Inc. and T-3 Energy Services as the top performers. Rosetta Resources, an oil and gas exploration and production company, rose sharply in the fourth quarter after reporting strong earnings. T-3 Energy Services, an oilfield products and service company, saw shares spike after the company announced it was being acquired by Robbins and Myers in the fourth quarter. Stock selection also contributed favorably in the producer durables sector. Shares of Ladish, a metal processing and fabrication company,

spiked after Allegheny Technologies agreed to acquire the company at a nearly 60% premium. MasTec, a building and construction company focusing on utilities and communications infrastructure, advanced on solid earnings and revenue growth.

Stock selection was weakest in the financial services sector, the only sector to materially detract from relative performance. Shares of NetSpend Holding Inc., a provider of pre-paid debit cards, declined due to poor business fundamentals, while investment-banking firm Greenhill tumbled on a weak fourth quarter and uneven mergers and acquisitions activity.

The largest change in sector weights during the period was a reduction in the healthcare sector. We sold specific companies within the medical device, healthcare services and pharmaceutical/biotechnology industries. We also reduced the fund’s weight in the consumer discretionary sector, albeit to a lesser extent, primarily by selling holdings in the retail industry. The biggest beneficiaries of the sales proceeds were the producer durables, technology and materials and processing sectors.

Outlook

Core inflation statistics have remained well within the Fed’s informal target range, but many commentators believe that the Fed may need to snug things up somewhat in the next few months. The Fed’s second round of large-scale Treasury purchases, which is referred to as “QE2”, is scheduled to end on June 30, 2011. At this point we do not expect an extension of asset purchases in the form of a “QE3” unless the economy takes an unexpected turn to the downside. Employment conditions have improved substantially over the past several months, and the employment reports for the months of February and March, 2011, made for some of the best reading we have seen in several years. Our working assumption is that investors and corporate executives need to plan for somewhat higher energy and other commodity input costs in the months ahead. This may be a factor in an eventual plateauing of corporate margins. However, this is built into our outlook in that we are anticipating about 15% earnings growth for the S&P 500 this year, decelerating to 10% or so next year.

What You Should Know:

Investments in the fund are subject to a number of risks. Please see the “Principal Risks” section of the fund’s prospectus. The purchase of fund shares should be seen as a long-term investment.

Market Conditions

Stocks rallied sharply during the six-month period, fueled by a modest improvement in U.S. business conditions and renewed investor optimism stemming from continued accommodation from the Federal Reserve Board. These factors, combined with better-than-expected corporate profits, drove share prices higher despite a host of challenges: political turmoil in North Africa and the Middle East and an earthquake, tsunami and nuclear crisis in Japan. Risk appetites stayed fairly high, and equities remained the vehicle of choice for investors. Overall, small-cap stocks led the market higher, and growth stocks outperformed value stocks.

Performance Results

For the six months ended March 31, 2011, Institutional Class shares of Loomis Sayles Small Cap Value Fund returned 26.11%. The fund outperformed its benchmark, the Russell 2000 Value Index, which returned 22.97% for the period.

Explanation of Fund Performance

All sectors of the portfolio delivered double-digit returns for the period. Stock selection, particularly in the producer durables and financial services sectors, drove the fund’s outperformance relative to the benchmark. Within producer durables, the fund’s position in Baldor Electric, a manufacturer of industrial electric motors, was its top contributor. The company agreed to be acquired by Switzerland-based power and automation engineering company ABB Ltd. for a 41% premium to prior trading levels. In the financial services sector, our stock selections in the brokerage, transaction processing and consumer lending industries contributed positively to performance. In addition, an underweight in the financial services sector helped, as the group trailed the small cap value index. Overall, the fund’s sector weights contributed positively to relative performance, with overweight positions in outperforming sectors, including producer durables and materials and processing, offsetting a slight underweight in energy stocks.

| 4

What You Should Know:

On a relative basis, an underweight in the energy sector, which was the market’s top-performing sector, and weak stock selection in the real estate investment trust (REIT) segment of the financials sector detracted from results. REIT stocks lagged during the six-month period. While the fund benefited from having a relatively small weight in the sector, stock selection lagged due to weaker performance in certain data center and health-care facility REITs.

Changes to the portfolio during the six months were largely driven by company-specific factors, with the net result showing an increase in technology holdings and a reduction in consumer durables. The technology weight increased with the addition of several communications-related stocks positioned to benefit from increasing demands on enterprise and carrier-based networks.

UNDERSTANDING YOUR FUND’S EXPENSES

As a mutual fund shareholder you incur two types of costs: (1) transaction costs 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.

7 |

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, 2010 through March 31, 2011. 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.

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 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:

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 distributions 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 subsequent to period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds’ 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. Investments in other open-end investment companies are valued at their net asset value each day. 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.

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.

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 values 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. 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, 2011 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.

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.

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 of items such as expired capital loss carryforwards, distribution redesignations 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.

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, 2010 was as follows:


	2010 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Small Cap Growth Fund	$	—	$	—	$	—
Small Cap Value Fund		2,321,057		—		2,321,057

As of September 30, 2010, the capital loss carryforwards were as follows:


Capital loss carryforward:	Small Cap Growth Fund			Small Cap Value Fund
Expires September 30, 2011	$	(59,283,040	)	$	—
Expires September 30, 2017		(14,995,800	)		(88,137,321	)
Expires September 30, 2018		(11,885,718	)		(58,500,125	)

Total capital loss carryforward	$	(86,164,558	)	$	(146,637,446	)

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Act”) was enacted. The Act modernizes several of the federal income and excise tax provisions related to RICs, and, with certain exceptions, is effective for taxable years beginning after December 22, 2010. Among the changes made are changes to the capital loss carryforward rules allowing for capital losses to be carried forward indefinitely. Rules in effect as of the report date limit the carryforward period to eight years. Capital loss carryforwards generated in taxable years beginning after effective date of the Act must be

| 32

Notes to Financial Statements – continued

March 31, 2011 (Unaudited)

fully used before capital loss carryforwards generated in taxable years prior to effective date of the Act; therefore, under certain circumstances, capital loss carryforwards available as of the report date, if any, may expire unused.

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 may 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.

For the six months ended March 31, 2011, none of the Funds had loaned securities under this agreement.

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

33 |

Notes to Financial Statements – continued

March 31, 2011 (Unaudited)

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 when 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, 2011, at value:

5. Management Fees and Other Transactions with Affiliates.

a. Management Fees. Loomis, Sayles & Company, L.P. (“Loomis Sayles”) serves as investment adviser to each Fund. Under the terms of the management agreements, each Fund pays a management fee at the following annual rates, calculated daily and payable monthly, based on each Fund’s average daily net assets:


Fund		Percentage of Average Daily Net Assets
Small Cap Growth Fund		0.75%
Small Cap Value Fund		0.75%

Loomis Sayles has given binding undertakings to the Funds to waive 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, 2012 and are reevaluated on an annual basis. Management fees payable, as reflected on the Statements of Assets and Liabilities, is net of waivers and/or expense reimbursements, if any, pursuant to these undertakings.

For the six months ended March 31, 2011, the expense limits as a percentage of average daily net assets under the expense limitation agreements were as follows:

Small Cap Value Fund	0.90%	1.15%	1.40%

Loomis Sayles shall be permitted to recover expenses it has borne under the expense limitation agreements (whether through waiver 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 waived/reimbursed fees or expenses more than one year after the end of the fiscal year in which the fees or expenses were waived/reimbursed.

For the six months ended March 31, 2011, the management fees for each Fund were as follows:


Fund	Management Fees		Percentage of Average Daily Net Assets
Small Cap Growth Fund	$	678,739	0.75%

Under the Retail Class Plans, 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 maintenance of shareholder accounts.

Under the Admin Class Plan, 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 Small Cap 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.

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 Hansberger International Series, 0.0500% of the next $15 billion, 0.0400% of the next $30 billion and 0.0350% 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 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.

For the six months ended March 31, 2011, each Fund paid the following administrative fees to Natixis Advisors:

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 to exceed 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.

	Sub-Transfer Agent Fees
Fund	Institutional Class		Retail Class		Admin Class

Small Cap Value Fund		209,839		274,357		74,719

e. Trustees Fees and Expenses. The Trusts 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. 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 an 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. 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.

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.

f. Payments by Affiliates. For the six months ended March 31, 2011, Loomis Sayles reimbursed Small Cap Growth Fund $36 for losses incurred in connection with a trading error.

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.

Effective April 21, 2011, each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Hansberger International Series, will participate 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 will participate in the line of credit.

From time to time, the Funds may have a concentration of several shareholders having a significant percentage of shares outstanding. Investment activities of these shareholders could have material impacts on the Funds. As of March 31, 2011, one shareholder account owned more than 5% of Small Cap Growth Fund’s total outstanding shares, representing 5.30% of the Fund’s net assets. Such ownership may be beneficially held by individuals or entities other than the owner of record.

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:

LOOMIS SAYLES HIGH INCOME OPPORTUNITIES FUND

Fund and manager review

FUND FACTS

Managers:

Matthew Eagan, CFA

Dan Fuss, CFA, CIC

Kathleen Gaffney, CFA

Elaine Stokes

Symbol:


Institutional Class		LSIOX

Objective:

High current income.

Capital appreciation is the Fund’s secondary objective.

Strategy:

Invests substantially all of its assets, and may invest up to 100% of its assets, in high income securities. High income securities are fixed-income securities that Loomis Sayles believes have the potential to generate relatively high levels of current income.

Fund Inception Date:

April 12, 2004

Net Assets:

$70.7 million

Market Conditions

Strong technical and fundamental factors helped keep the high-yield and equity markets resilient throughout the six-month period, despite several negative events, including headline risk in Japan, the Middle East and North Africa, concerns about European sovereign debt and ratings downgrades for corporate credits in peripheral euro zone countries. The yield curve steadily steepened during the period, driven mostly by shifting growth expectations as economic data continued to improve. With the curve so steep, investors are being compensated for investing further along on the yield curve.

Performance Results

For the six months ended March 31, 2011, Loomis Sayles High Income Opportunities Fund returned 9.06%. The fund outperformed its benchmark, the Barclays Capital U.S. Corporate High-Yield Bond Index, which returned 7.23% for the period.

Explanation of Fund Performance

Our out-of-benchmark allocation to convertible securities made the largest contribution to the fund’s relative return for the period. In particular, strong underlying equity performance from the communications, automotive, technology and healthcare industries drove the favorable performance. In addition, issue selection remained critical within the high-yield space, where we focused on credits with positive fundamentals, low default probability and solid balance sheets. Within the high-yield sector, industrials contributed significantly to absolute and relative performance, particularly among holdings in the technology, communications and energy industries. High-yield utilities also contributed positively, with electric names buoying the sector.

With the yield curve steepening significantly during the period, the fund’s longer duration weighed on performance. The fund had considerable exposure to the middle and the longer portions of the curve. In addition, while exposure to the consumer non-cyclical sector helped on an absolute basis, it weighed on relative performance. Lackluster returns from issues in the pharmaceutical, supermarket, and food and beverage industries put downward pressure on the sector.

Outlook

Strong liquidity, markets in transition, geopolitical turmoil, continued economic recovery and tragic natural disasters garnered significant attention from market participants during the first quarter of 2011. Many of these themes will continue to dominate investor consciousness going forward.

We believe markets remain in transition regarding interest rates, with pressures building both globally and domestically. Globally, growth in many areas of the world remains robust; however, inflation concerns have begun to attract attention. Central banks will likely continue to shift toward less accommodative policy as 2011 progresses. We anticipate the Federal Reserve Board’s program of Treasury purchases in the United States, which is referred to as “QE2” (short for quantitative easing), will end during the second quarter and believe the U.S. economic recovery has sufficient momentum to continue expanding without outsized government stimulus.

Our assessment of the fundamental underpinnings of the corporate sector remains positive. In general, corporations are proceeding conservatively with regard to hiring and capital expenditures. Merger and acquisition activity has increased recently, and we believe there is room for more growth in that space. Valuations in the corporate bond space are generally fair, with investor demand for yield providing support and liquidity to the high-yield, investment-grade and convertible sectors.

We continue to position the fund for global economic recovery, as well as a gradual upward bias in interest rates. We continue to emphasize yield advantage, global diversification and specific bond picking within the fund.

LOOMIS SAYLES SECURITIZED ASSET FUND

Fund and manager review

FUND FACTS

Managers:

Clifton Rowe, CFA

Alessandro Pagani, CFA

Symbol:


Institutional Class		LSSAX

Objective:

High level of current income consistent with capital preservation.

Strategy:

Invests at least 80% of its net assets (plus any borrowings made for investment purposes) in a diversified portfolio of securitized assets, such as mortgage-backed and other asset-backed securities.

Fund Inception Date:

March 2, 2006

Net Assets:

$690.2 million

Market Conditions

Sentiment generally remained healthy in the domestic financial markets, despite disruptions abroad, including sovereign debt concerns in Europe, civil unrest in the Middle East and North Africa and the earthquake in Japan. While the Federal Reserve Board (the Fed) maintained its low-interest-rate policy, stronger macroeconomic data and improved economic growth prospects caused market interest rates to increase slightly. Against a backdrop of low interest rates, investor demand for yield in the U.S. fixed-income markets persisted. Sectors offering a yield advantage benefited.

Performance Results

For the six months ended March 31, 2011, Loomis Sayles Securitized Asset Fund returned 2.29%. The fund outperformed its benchmark, the Barclays Capital U.S. Securitized Bond Index, which returned 0.97% for the period.

Explanation of Fund Performance

A combination of favorable security selection and yield curve positioning helped the fund outperform its benchmark for the six-month period. In addition, our overweight allocation to commercial mortgage-backed securities (CMBS) contributed favorably to performance. The fund’s holdings were primarily senior securities well protected from credit risk and offering compelling value. We acquired the majority of the fund’s CMBS in late 2008 and early 2009, when prices were severely depressed. Since then, they have experienced significant price appreciation, driven by investor demand for yield. In the asset-backed securities (ABS) segment, we favored high quality issues, including auto equipment-backed securities, which performed well. The fund’s shorter average duration also contributed positively, as improving economic growth prospects caused rates to rise across the curve. Duration is a measure of interest-rate sensitivity.

Overall, the fund’s higher quality securities detracted from relative performance due to investor preference for lower quality securities during the period, but returns were still positive. Also, a substantial underweight to the 30-year mortgage-backed sector, which outperformed the benchmark, had a slightly negative influence on relative performance. The fund’s overweight allocation to the ABS space detracted from relative results, but this was offset by strong security selection and shorter relative duration within the sector.

Outlook

We expect the Fed will continue its current interest rate policy well into 2011. In the intermediate term, we anticipate interest rates will gradually increase as modest economic growth persists. We are maintaining overweights in CMBS and ABS, and while we expect fundamental weakness to persist in the mortgage and consumer loan market, we believe the securities we currently hold are protected from significant credit risk and can continue to offer favorable risk-adjusted returns. Furthermore, we expect our government-sponsored enterprise (GSE) mortgage positions to benefit from a relatively stable interest rate environment. This sector continues to offer a modest yield advantage with strong credit quality. We will continue to look for opportunities to take advantage of the steep yield curve and will focus on income, rather than price appreciation.

A description of the Funds’ proxy voting policies and procedures is available without charge, upon request, (i) by calling Loomis Sayles at 800-633-3330; (ii) on the Funds’ website, www.loomissayles.com, and (iii) on the Securities and Exchange Commission’s (“SEC’s”) website at www.sec.gov. Information about how the Funds voted proxies relating to portfolio securities during the 12-month period ended June 30, 2010 is available on (i) the Funds’ website and (ii) the SEC’s website.

Quarterly Portfolio Schedules

The Funds file a complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The Funds’ Forms N-Q are available on the SEC’s website at www.sec.gov and may be reviewed and copied at the SEC’s Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling 800-SEC-0330.

UNDERSTANDING FUND EXPENSES

Typically, mutual fund shareholders incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution fees (12b-1 fees), and other fund expenses. However, the Funds are unlike other mutual funds; they do not charge any fees or expenses.

You should be aware that shares in the Funds are available only to institutional investment advisory clients of Loomis, Sayles & Company, L.P. (“Loomis Sayles”) and Natixis Asset Management Advisors, L.P. (“Natixis Advisors”) and to participants in “wrap fee” programs sponsored by broker dealers and investment advisers that may be affiliated or unaffiliated with the Funds, Loomis Sayles or Natixis Advisors. The institutional investment advisory clients of Loomis Sayles and Natixis Advisors pay Loomis Sayles or Natixis Advisors a fee for their investment advisory services, while participants in “wrap fee” programs pay a “wrap fee” to the program’s sponsor. The “wrap fee” program sponsors, in turn, pay a fee to Natixis Advisors. “Wrap fee” program participants should read carefully the wrap fee brochure provided to them by their program’s sponsor and the fees paid by such sponsor to Natixis Advisors. Shareholders pay no additional fees or expenses to purchase shares of the Funds. However, shareholders will indirectly pay a proportionate share of those costs, such as brokerage commissions, taxes and extraordinary expenses, that are borne by the Funds through a reduction in each Fund’s net asset value.

The first line in each Fund’s table shows the actual amount of Fund expenses ($0) you would have paid on a $1,000 investment in the Fund from October 1, 2010 through March 31, 2011. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual Fund returns and expenses.

The second line in each Fund’s table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio (0%) 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 the other funds.

Notes To Financial Statements

March 31, 2011 (Unaudited)

1. Organization. Loomis Sayles Funds I (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 High Income Opportunities Fund (the “High Income Opportunities Fund”)

Loomis Sayles Securitized Asset Fund (the “Securitized Asset Fund”)

Each Fund offers Institutional Class shares. The Funds’ shares are offered exclusively to investors in “wrap fee” programs approved by Natixis Asset Management Advisors, L.P. (“Natixis Advisors”) and/or Loomis, Sayles & Company, L.P. (“Loomis Sayles”) and to institutional advisory clients of Natixis Advisors or Loomis Sayles that, in each case, meet the Funds’ policies as established by Loomis Sayles.

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. Futures contracts are valued at their most recent settlement price. Short-term obligations purchased with an original or remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. Investments in other open-end investment companies are valued at their net asset value each day. 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.

The High Income Opportunities 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.

25 |

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 High Income Opportunities 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 High Income Opportunities 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 High Income Opportunities Fund may enter into forward foreign currency contracts, including forward foreign cross 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 Statements 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 as collateral for the Funds’ or counterparty’s net obligations under the contracts.

There were no forward currency contracts held by the Fund during the six months ended March 31, 2011.

e. Futures Contracts. The Funds may enter into futures contracts. Futures contracts are agreements between two parties to buy and sell a particular commodity, instrument or index for a specified price on a specified future date.

When a Fund enters into a futures contract, it is required to deposit with (or for the benefit of) its broker an amount of cash or short-term high quality securities as “initial margin”. As the value of the contract changes, the value of the futures contract position increases or declines. Subsequent payments, known as “variation margin”, are made or received by a Fund, depending on the price fluctuations in the fair value of the contract and the value of cash or securities on deposit with the broker. The aggregate principal amounts of the contracts are not recorded in the financial statements. Fluctuations in the value of the contracts are recorded in the Statements of Assets and Liabilities as an asset (liability) and in the Statements of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized gains (losses). Realized gain or loss on a futures position is equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed, minus brokerage commissions. When a Fund enters into a futures contract, certain risks may arise, such as illiquidity in the futures market, which may limit a Fund’s ability to close out a futures contract prior to settlement date, and unanticipated movements in the value of securities, commodities or interest rates.

Futures contracts are exchange-traded. Exchange-traded futures 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.

There were no futures contracts held by the Funds during the six months ended March 31, 2011.

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, 2011 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.

The High Income Opportunities 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.

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

| 26

Notes To Financial Statements – continued

March 31, 2011 (Unaudited)

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 of items such as premium amortization, defaulted bonds, distribution redesignations and paydown gains and 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 defaulted bond income accruals, premium amortization, securities lending collateral gain/loss adjustments, contingent payment debt instruments 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, 2010 was as follows:


	2010 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
High Income Opportunities Fund	$	5,690,124	$	—	$	5,690,124
Securitized Asset Fund		25,176,915		—		25,176,915

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

As of September 30, 2010, the capital loss carryforwards and post-October losses were as follows:


Capital loss carryforward:	High Income Opportunities Fund			Securitized Asset Fund
Expires September 30, 2017	$	(811,815	)	$	—
Expires September 30, 2018		(5,225,445	)		(1,367,506	)

Total capital loss carryforward	$	(6,037,260	)	$	(1,367,506	)

Deferred net capital losses (post-October 2009)	$	—		$	(239,014	)

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. Delayed Delivery Commitments. The Funds may purchase securities, including those designated as TBAs in the Portfolio of Investments, for which delivery or payment will occur at a later date, beyond the normal settlement period. The price of the security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The security and the obligation to pay for it are recorded by the Funds at the time the commitment is entered into. The actual security that will be delivered to fulfill a TBA trade is not designated at the time of the trade. The security is “to be announced” 48 hours prior to the established trade settlement date. The value of the security may vary with market fluctuations during the time before the Funds take delivery of the security. No interest accrues to the Funds until the transaction settles. When the Funds enter into such a transaction, collateral consisting of liquid securities or cash and cash equivalents is required to be segregated or earmarked at the custodian in an amount at least equal to the amount of the Funds’ commitment.

Purchases of delayed delivery securities may have a similar effect on the Funds’ net asset value as if the Funds had created a degree of leverage in its portfolio. Risks may arise upon entering into such transactions from the potential inability of counterparties to meet their obligations under the transactions. Additionally, losses may arise due to changes in the value of the underlying securities.

j. 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

27 |

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 may 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.

For the six months ended March 31, 2011, none of the Funds had loaned securities under this agreement.

k. 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.

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;

•

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, 2011, at value:

4. Purchases and Sales of Securities. For the six months ended March 31, 2011, purchases and sales of securities (excluding short-term investments and including paydowns) were as follows:


	U.S. Government/Agency Securities				Other Securities
Fund	Purchases		Sales		Purchases		Sales
High Income Opportunities Fund	$	—	$	—	$	11,190,013	$	12,212,298
Securitized Asset Fund		787,326,283		792,184,527		172,995,127		42,950,638

5. Management Fees and Other Transactions with Affiliates.

a. Management Fees. Loomis Sayles has agreed to pay, without reimbursement from the Funds or the Trust, the following expenses of the Funds: compensation to Trustees of the Trust who are not “interested persons” (as defined in the 1940 Act) of the Trust; registration, filing and other fees in connection with requirements of regulatory authorities; the charges and expenses of any entity appointed by the Funds for custodial, paying agent, shareholder servicing and plan agent services; charges and expenses of the independent registered public accounting firm retained by the Funds; charges and expenses of any transfer agents and registrars appointed by the Funds; any cost of certificates representing shares of the Funds; legal fees and expenses in connection with the day-to-day affairs of the Funds, including registering and qualifying its shares with Federal and State regulatory authorities; expenses of meetings of shareholders and Trustees of the Trust; the costs of services, including services of counsel, required in connection with the preparation of the Funds’ registration statements and prospectuses, including amendments and revisions thereto, annual, semi-annual and other periodic reports of the Funds, and notices and proxy solicitation material furnished to shareholders of the Funds or regulatory authorities, and any costs of printing or mailing these items; and the Funds’ expenses of bookkeeping, accounting and financial reporting, including related clerical expenses.

Loomis Sayles serves as investment adviser to each Fund. Under the terms of each management agreement, Loomis Sayles does not charge the Funds an investment advisory fee, also known as a management fee, or any other fee for those services or for bearing those expenses. Although the Funds do not compensate Loomis Sayles directly for services under the advisory agreement, Loomis Sayles will typically receive an advisory fee from the sponsors of “wrap programs,” who in turn charge the programs’ participants.

b. Service and Distribution Fees. Natixis Distributors, L.P. (“Natixis Distributors”), a wholly-owned subsidiary of Natixis US has entered into a distribution agreement with the Trust. Pursuant to this agreement, Natixis Distributors serves as principal underwriter of the Funds of the Trust. Natixis Distributors currently is not paid a fee for serving as distributor for the Funds. Loomis Sayles has agreed to reimburse Natixis Distributors to the extent that Natixis Distributors incurs expenses in connection with any redemption of Fund shares.

c. Administrative Fees. Natixis Advisors provides certain administrative services for the Funds and contracts with State Street Bank to serve as sub-administrator. Natixis Advisors is a wholly-owned subsidiary of Natixis US. Loomis Sayles has agreed to pay, without reimbursement from the Trust or Funds, fees to Natixis Advisors for services to the Funds.

d. Trustees Fees and Expenses. The Trust does not pay any compensation directly to its officers or Trustees who are directors, officers or employees of Natixis Advisors, Natixis Distributors, Natixis US or their affiliates. 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 an 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. These fees are allocated among the funds in Natixis Funds Trust I, Natixis Funds Trust II, Natixis Funds Trust IV, Gateway Trust (“Natixis Funds Trusts”), Loomis Sayles Funds I, Loomis Sayles Funds II (“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.

6. Line of Credit. Each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and 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

| 30

Notes To Financial Statements – continued

March 31, 2011 (Unaudited)

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, 2011, none of the Funds had borrowings under these agreements.

7. Concentration of Ownership. From time to time, the Funds may have a concentration of several shareholders having a significant percentage of shares outstanding. Investment activities of these shareholders could have material impacts on the Funds. As of March 31, 2011, four shareholder accounts owned more than 5% of High Income Opportunities Fund’s outstanding shares, representing 38.83% of the Fund’s net assets. Such ownership may be beneficially held by multiple individuals or entities other than the owner of record.

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

Institutional Class		LSBDX
Retail Class		LSBRX
Admin Class		LBFAX

Objective:

High total investment return through a combination of current income and capital appreciation

Strategy:

Invests primarily in investment-grade fixed-income securities, although it may invest up to 35% of assets in lower-quality fixed-income securities and up to 20% of its assets in preferred stocks. The fund may invest any portion of its assets in Canadian securities and up to 20% of assets in other foreign securities, including emerging markets securities.

Fund Inception Date:

May 16, 1991

Class Inception Date:

Institutional Class:

May 16, 1991

Retail Class:

December 31, 1996

Admin Class:

January 2, 1998

Net Assets:

$20,025.1 million

Market Conditions

As attention shifted from economic recovery to economic growth, investors began to displace lingering economic pessimism with optimism. The transition was far from smooth though, as new concerns materialized and old ones resurfaced. Specifically, increased anxiety regarding sovereign debt solvency in Europe, unrest in North Africa and the Middle East, precarious macroeconomic data, earthquakes in Japan and New Zealand and China’s lending restrictions percolated through global credit markets in waves during the period, alternately fostering and stymieing investors’ appetite for risk. The Federal Reserve’s second round of quantitative easing, popularly referred to as “QE2,” tempered modest price decreases that occurred during the period. Overall, liquidity returned to the credit markets during the period, largely in the form of new issuance as firms sought to refinance debt. This trend supported high-yield and investment-grade names.

Performance Results

For the six months ended March 31, 2011, Institutional Class shares of Loomis Sayles Bond Fund returned 5.64%. The fund outperformed its benchmark, the Barclays Capital U.S. Government/Credit Bond Index, which returned -1.90% for the period.

Explanation of Fund Performance

Positive security selection primarily accounted for the fund’s outperformance. Tentative signs of stability in Europe, namely the acceptance of euro zone bank stress tests, allayed investor fears, and major currencies rallied against the U.S. dollar. This translated into sizable contributions from our investments denominated in the Canadian dollar, Australian dollar, New Zealand dollar and Norwegian krone. Similarly, bonds issued in the Indonesian rupiah, Singapore dollar and South Korean won contributed modestly to performance. In addition, our holdings in equity-sensitive convertible bonds and preferred securities advanced due to healthy stock market performance during the period. Among high-yield bonds, the industrials sector was the top performer, with the strongest returns coming from issues in the technology, consumer cyclical and communications segments. Our allocation to high-yield financials also contributed positively. Our underweight in U.S. Treasuries helped performance, as investors favored riskier assets in their search for yield, causing Treasuries to underperform.

A small position in government-owned securities had a negative effect on relative performance, primarily due to a long duration stance within the allocation. (Duration is a measure of interest rate sensitivity.) Additionally, the fund’s overall longer-than-benchmark duration detracted from returns because yields increased during the period. Furthermore, while most non-U.S.-dollar positions contributed positively, holdings denominated in the euro lagged on fears of sovereign risk.

Outlook

We believe markets remain in transition regarding interest rates, with pressures building both globally and domestically. Globally, growth in many areas of the world remains robust; however, inflation concerns have begun to attract attention. Central banks will likely continue to shift toward less accommodative policy as 2011 progresses. We anticipate the Federal Reserve’s program of Treasury purchases in the United States will end during the second quarter and believe the U.S. economic recovery has sufficient momentum to continue expanding without outsized government stimulus.

Managers:

Ken Buntrock, CFA, CIC

Institutional Class		LSGBX
Retail Class		LSGLX

Objective:

High total investment return through a combination of high current income and capital appreciation

Strategy:

Invests primarily in investment grade fixed-income securities worldwide, although it may invest up to 20% of assets in lower-quality fixed-income securities.

Fund Inception Date:

May 10, 1991

Class Inception Date:

Institutional Class:

May 10, 1991

Retail Class:

December 31, 1996

Net Assets:

$2,294.6 million

Market Conditions

Government bond yields rose at the end of 2010, as investors favored risk in the form of equity and other higher-yielding investments in the wake of improving economic data. But, mid-way through the first quarter of 2011, deteriorating sentiment and increased uncertainty began to test risk preference. Higher oil prices, turmoil in the Middle East and North Africa, and the Japanese disaster caused the market to revise global economic growth forecasts down. Meanwhile, the ambiguity of European sovereign debt concerns remained. Nevertheless, riskier assets performed well during the period, despite mounting uncertainty and rising interest rates around the globe. Global credit strongly outperformed government-issued bonds on a duration-matched basis, while lower-quality bonds generally outperformed high-quality bonds. Among currencies, the U.S. dollar finished the period weaker versus all major currencies.

Performance Results

For the six months ended March 31, 2011, Institutional Class shares of Loomis Sayles Global Bond Fund returned 1.37%. The fund outperformed its benchmark, the Barclays Capital Global Aggregate Bond Index, which returned -0.10% for the period.

Explanation of Fund Performance

Favorable security selection and an overweight in corporate bonds, along with an underweight in government bonds, drove the fund’s outperformance relative to the benchmark. Specifically, our preference for cyclical corporate bonds within the technology and communications industries aided performance. From a quality perspective, the fund’s overweights in BBB-rated credits and high-yield bonds boosted relative returns. From a currency perspective, we capitalized on a weak U.S. dollar with overweights in developing and non-yen, -euro and –U.S.-dollar currencies, including the Indonesian rupiah, Malaysian ringgit, Mexican peso, Singapore dollar, Danish krone, Norwegian krone and Swedish krona. To better align the currency exposure of specific holdings, we traded foreign currency contracts throughout the period. These derivatives were an integral part of the fund’s overall currency strategy, which boosted returns for the period. Country selection also enhanced returns, primarily due to substantial underweights in the European local markets. In addition, the fund’s shorter-than-benchmark duration across the U.S.-dollar-based corporate, securitized and Treasury sectors enhanced returns, as yields rose across the curve. Duration is a measure of interest rate sensitivity.

The fund’s underweight in the euro detracted from returns, as the currency strengthened against the U.S. dollar during the period. Euro positioning also dampened relative performance from a yield curve perspective. As rates rose across the curve, the fund’s average long-duration exposure hurt relative performance.

Outlook

We are maintaining overweight positions in non-yen Asian currencies, because we expect the currency-positive effects of tighter central bank policies to outweigh the currency-negative effects of weaker local equity markets. The impact of higher oil prices on inflation has resulted in a more hawkish tone coming from the European Central Bank (ECB). This is why the euro has firmed. Oil price hikes increase the likelihood of ECB hikes, widening the euro-to-dollar spread in short-term rates. We used the latest bond rally to tweak duration lower in developed countries. We believe there are clear risks to growth in 2012, but for now we remain global expansion optimists and are therefore also retaining our corporate credit positions. Finally, positions in emerging markets, commodity currencies and non-Japan Asian countries still appear warranted, given the global growth and rates outlook. Nevertheless, some equity volatility is likely following the conclusion of the Federal Reserve Board’s quantitative easing, which involves large-scale purchases of Treasury securities. As long as growth prospects remain firm, we anticipate spillover into credit spreads will be relatively minor.

Objective:

Class Inception Date:

Institutional Class:

Retail Class:

Net Assets:

$17.3 million

Market Conditions

While still close to historical lows, interest rates began to move higher at the end of 2010, a trend that continued through the first quarter of 2011. A preference for riskier assets prevailed for most of the first quarter, but headline news, including a severe earthquake in Japan, political instability in the Middle East and North Africa, and the re-emergence of European sovereign-debt woes contributed to volatility that negatively influenced investor sentiment. Despite these headwinds, the markets remained relatively resilient, as positive corporate earning news and macroeconomic indicators supported the continuation of the economic recovery.

Performance Results

For the six months ended March 31, 2011, Institutional Class shares of Loomis Sayles Inflation Protected Securities Fund returned 1.40%. The fund performed in line with its benchmark, the Barclays Capital U.S. Treasury Inflation Protected Securities Index, which returned 1.42% for the period.

Explanation of Fund Performance

Against a backdrop of higher interest rates, shorter-duration Treasury Inflation Protected Securities (TIPS) led fund performance during the period. The fund’s slightly-shorter-than-benchmark yield curve positioning contributed positively to performance and helped the fund’s TIPS outperform those of the benchmark.

In addition, an overweight to corporate credit – particularly our small allocation to high-yield industrials – helped relative results, as riskier assets performed better during the period. Among corporates, the largest contribution to return came from holdings in the basic industry, capital goods and insurance areas. Nevertheless, our corporate exposure favored longer-duration issues, and rising interest rates dampened the sector’s positive contribution. Furthermore, corporate returns in the consumer non-cyclical and technology sectors were weak and slightly detracted from relative performance.

The fund’s exposure to the Mexican peso and Canadian dollar also helped relative performance. Both currencies appreciated versus the U.S. dollar, due to sustained demand for local market commodities and continued low rates in the United States.

Outlook

Higher food and commodity prices have stoked expected inflation levels, which helped TIPS outperform nominal Treasuries. Despite recent bouts of volatility, the market has shown to be fairly resilient, offering further conviction that the economic recovery may continue as anticipated. The continuation of the Federal Reserve Board’s (the Fed’s) loose monetary policy may cause inflation speculation to mount over time, which could increase breakeven rates (the difference between the nominal yields offered by Treasuries and the real, or inflation-adjusted, yields offered by TIPS). Further out, when the Fed shifts toward a more hawkish stance on inflation and raises interest rates, inflation expectations at the longer end of the yield curve may dampen. In this scenario, real and nominal yields for long-dated issues would converge, effectively lowering breakeven rates at the long end of the yield curve. If this occurs, we may find opportunities at the shorter and intermediate parts of the yield curve to maximize returns. Additionally, corporate earnings generally have been positive, and we will continue to hold a small overweight to the sector, seeking to opportunistically add value when what we view as attractive risk/reward issues become available.

For illustrative purposes, the chart above reflects the growth of a hypothetical investment of $100,000 in the fund, for the last ten years. The chart above also reflects the growth of a hypothetical investment in the former primary benchmark of the fund, the Barclays Capital U.S. Government Bond Index (the “Former Benchmark”), compared to the performance of the fund from March 31, 2001 through December 31, 2004. On December 15, 2004, in connection with a change of the fund’s investment objective, the fund changed its primary benchmark to the Barclays Capital U.S. Treasury Inflation Protected Securities Index (the “New Benchmark”). Since index performance data is not available coincident with the date of the fund’s strategy change, comparative data for the fund’s New Benchmark begins on December 31, 2004. The chart above reflects the growth of a hypothetical investment in the New Benchmark, compared to the performance of the fund, from December 31, 2004, through March 31, 2011. The chart above also compares the performance of the fund to the Lipper Treasury Inflation Protected Securities Funds Index from December 31, 2004 through March 31, 2011. The performance of the New Benchmark and of the Lipper Treasury Inflation Protected Securities Funds Index was linked to the performance of the Former Benchmark as of December 31, 2004.

FUND FACTS

Managers:

Daniel Fuss, CFA, CIC

Matthew Eagan, CFA

Kathleen Gaffney, CFA

Elaine Stokes

Symbol:


Institutional Class		LSHIX

Objective:

High total investment return through a combination of current income and capital appreciation

Strategy:

Invests in primarily lower-quality fixed-income securities and other securities that are expected to produce a relatively high level of income, (including income-producing preferred and common stocks).

The fund may invest any portion of its assets in Canadian securities and up to 50% of assets in other foreign securities, including emerging markets securities.

Fund Inception Date:

June 5, 1996

Fund Registration Date:

March 7, 1997

Net Assets:

$429.4 million

Market Conditions

A gradually improving global economic environment drove risk appetite, while stronger corporate balance sheets and employment gains generated additional investor confidence. In this environment, high-yield credits generally outperformed their investment-grade counterparts, and investors were rewarded for taking on higher degrees of risk. Record market liquidity allowed debt issuers to refinance old lines of credit at more beneficial terms, as investors reached for yield in the continued artificially-low interest rate environment. Challenges emerged, as European sovereign-debt worries continued to pop up on news of elections, resignations and banking sector troubles. In addition, political upheaval in the Middle East and North Africa led to volatility in the global markets and created uncertainty regarding oil shipments. The natural and nuclear disasters in Japan also rattled the markets, as many of the country’s manufacturers had to shut down operations. Investors also feared that Japan, one of the largest holders of U.S. Treasuries, would liquidate its positions to rebuild.

Performance Results

For the six months ended March 31, 2011, Loomis Sayles Institutional High Income Fund returned 9.60%. The fund outperformed its benchmark, the Barclays Capital U.S. Corporate High-Yield Bond Index, which returned 7.23% for the period.

Explanation of Fund Performance

Favorable security selection and exposure to out-of-benchmark sectors were the main drivers of the fund’s outperformance relative to the benchmark. In particular, positions in convertible bonds and a small allocation to equities boosted relative returns due to strong underlying equity-market performance. In the high-yield sector, holdings in the industrials, utilities and financial segments posted strong returns, while consumer non-cyclical and cyclical, technology, finance, communication, capital goods and energy credits represented some of the strongest industry-based returns.

Although investment-grade securities and securities denominated in foreign currencies provided positive returns, the returns they generated were not as strong as the return of the benchmark. A small allocation to U.S. Treasuries posted negative results. While investors flocked to relatively safer assets during periods of increased volatility, a preference for risk dominated during the six-month period.

Outlook

We believe markets remain in transition regarding interest rates, with pressures building both globally and domestically. Globally, growth in many areas of the world remains robust; however, inflation concerns have begun to attract attention. Central banks will likely continue to shift toward less accommodative policy as 2011 progresses. We anticipate the Federal Reserve’s program of Treasury purchases in the United States, which is referred to as “QE2” (short for quantitative easing), will end during the second quarter and believe the U.S. economic recovery has sufficient momentum to continue expanding without outsized government stimulus.

For the six months ended March 31, 2011, Institutional Class shares of Loomis Sayles Intermediate Duration Bond Fund returned -0.34%. The fund outperformed its benchmark, the Barclays Capital U.S. Intermediate Government/Credit Bond Index, which returned -1.11% for the period.

Explanation of Fund Performance

Favorable issue selection and sector allocations contributed to the fund’s outperformance. In particular, commercial mortgage-backed securities (CMBS) continued to offer attractive value for the fund, and an overweight position in CMBS was the largest individual contributor to performance during the period. Our allocations remained concentrated in higher-quality, super-senior CMBS. Issue selection among U.S. corporate bonds also made a positive contribution to performance, helping to buoy returns in a challenging market environment. In particular, the fund’s holdings in the communications, energy and basic industry sectors boosted relative return. A small allocation to high-yield corporate securities, focused in the industrials segment, provided a small boost to excess return and generated the largest gains for the fund. Additionally, an underweight in U.S. Treasuries helped performance, because returns among Treasuries were largely negative in the rising-rate environment, and riskier assets performed better.

The fund’s longer-duration positions tended to underperform during the period, as interest rates ratcheted higher. Despite remaining in line with the benchmark in terms of duration, a negative yield curve effect was the largest detractor from the fund’s performance. Returns from Treasury securities declined during the period. Longer-duration positions weighed on performance, while issues at the shorter end of the yield curve eked out small positive gains. Within the corporate sector, returns were weakest in the capital goods, technology and transportation industries.

Outlook

We anticipate maintaining an overweight in corporate securities and structured assets while remaining underweight in Treasuries for the foreseeable future. There is a more cautious view of interest rates and yield curve effects going forward, due to the Federal Reserve Board’s scheduled conclusion to its second round of quantitative easing, popularly referred to as “QE2,” by the end of the second quarter. We expect to maintain the fund’s relatively neutral duration versus the benchmark. Anticipating future volatility as QE2 winds down, we will continue to diversify the fund’s holdings. In addition, we will continue to use Treasuries for liquidity and duration management.

FUND FACTS

Managers:

Daniel Fuss, CFA, CIC

Matthew Eagan, CFA

Kathleen Gaffney, CFA

Elaine Stokes

Symbols:


Institutional Class		LSIGX

Objective:

Above-average total investment return through a combination of current income and capital appreciation

Strategy:

Invests in primarily investment-grade fixed-income securities, although it may invest up to 10% of its assets in lower-quality fixed-income securities and up to 10% of its assets in preferred stocks. The fund may invest any portion of its assets in securities of Canadian issuers and up to 20% of assets in securities of other foreign issuers, including emerging markets.

Fund Inception Date:

July 1, 1994

Fund Registration Date:

March 7, 1997

Net Assets:

$455.4 million

Market Conditions

Riskier assets rallied during the period amid positive macroeconomic indicators and continued support from the Federal Reserve Board’s quantitative easing program, which involves significant purchases of Treasury securities. Many fourth-quarter 2010 earnings reports surpassed expectations, and consumer confidence trended higher. Late in the period, unrest in the Middle East and a devastating earthquake in Japan brought volatility back to the market. Commodity prices increased sharply, and inflationary pressures prompted China to raise reserve rates. Oil prices hit 12-month highs, as unrest in North Africa created supply concerns. On a bright note, the U.S. unemployment rate dropped to 8.8% in March from a high of 9.8% in November. Demand for risk and a technical rally continued to drive returns in corporate and securitized debt. Overall, corporate bonds outpaced U.S. Treasuries, as yield spreads continued to tighten.

Performance Results

For the six months ended March 31, 2011, Loomis Sayles Investment Grade Fixed Income Fund returned 3.39%. The fund outperformed its benchmark, the Barclays Capital U.S. Government/Credit Bond Index, which returned -1.90% for the period.

Explanation of Fund Performance

Strong security selection and sector positioning within corporate credit, high-yield, non-U.S. dollar and convertibles were the primary drivers of the fund’s outperformance. In particular, a substantial allocation to the non-U.S.-dollar space boosted relative performance, as the commodity-rich nations of Canada, Australia, Norway and New Zealand provided the strongest returns. Additionally, strong security selection in the investment-grade corporate bond sector bolstered relative performance, with names in the finance, insurance, communication and transportation industries offering the best returns. A modest allocation to high-yield corporate bonds also contributed favorably, particularly in the consumer cyclical, transportation and finance industries. The fund’s commercial mortgage-backed securities and asset-backed securities offered strong returns relative to Treasuries and continued to support relative performance, while exposure to convertible bonds and preferred stock benefited from strong returns in the equity market. Selected names in the automotive, banking, technology and consumer non-cyclical industries performed the best. In addition, an underweight position in U.S. Treasuries helped relative performance, as demand for risk drove investors away from normally safer sectors, which lagged for the period.

The only notable detractor to relative performance was the fund’s yield-curve positioning. Specifically, the fund’s slightly-longer-than-benchmark duration weighed on returns, as the yield curve shifted up during the period. Duration is a measure of interest-rate sensitivity.

Outlook

We believe markets remain in transition regarding interest rates, with pressures building both globally and domestically. Globally, growth in many areas of the world remains robust; however, inflation concerns have begun to attract attention. Central banks will likely continue to shift toward less accommodative policy as 2011 progresses. We anticipate the Federal Reserve’s program of Treasury purchases in the United States, which is referred to as “QE2” (short for quantitative easing), will end during the second quarter and believe the U.S. economic recovery has sufficient momentum to continue expanding without outsized government stimulus.

UNDERSTANDING YOUR FUND’S EXPENSES

As a mutual fund shareholder you incur two types of costs: (1) transaction costs, 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 each fund’s 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 of fund shares shows the actual amount of Fund expenses you would have paid on a $1,000 investment in the fund from October 1, 2010 through March 31, 2011. 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 Period column as shown below for your Class.

The second line in the table for each class of fund shares provides information about hypothetical account values and hypothetical expenses based on the fund’s actual expense ratios and an assumed rate of return of 5% per year before expenses, which is not the fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid on your investment for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Notes to Financial Statements

March 31, 2011 (Unaudited)

1. Organization. Loomis Sayles Funds I (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. Shares of certain funds in the Trust were first registered under the Securities Act of 1933 (the “1933 Act”) effective March 7, 1997 (subsequent to their commencement of investment operations). 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 Bond Fund (the “Bond Fund”)

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

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

Loomis Sayles Inflation Protected Securities Fund (the “Inflation Protected Securities Fund”)

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

Loomis Sayles Intermediate Duration Bond Fund (the “Intermediate Duration Bond Fund”)

Loomis Sayles Investment Grade Fixed Income Fund (the “Investment Grade Fixed Income Fund”)

Each Fund offers Institutional Class shares. Bond Fund, Global Bond Fund, Inflation Protected Securities Fund and Intermediate Duration Bond Fund also offer Retail Class shares. In addition, Bond Fund offers Admin Class shares.

Most expenses of the Trust 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 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 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 distributions 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 subsequent to period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds’ 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. Futures contracts are valued at their most recent settlement price. Swap agreements are valued based on prices supplied by a pricing service, if available, or quotations obtained from broker-dealers. Short-term obligations purchased with an original or remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. Investments in other open-end investment companies are valued at their net asset value each day. 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.

b. Investment Transactions and Related Investment Income. Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculation. However, for financial reporting purposes, investment transactions are reported 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.

Certain Funds 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. Certain Funds may enter into forward foreign currency contracts, including forward foreign cross 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 may 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 as collateral for the Funds’ or counterparty’s net obligations under the contracts.

f. Swap Agreements. Each Fund may enter into credit default swaps. A credit default swap is an agreement between two parties (the “protection buyer” and “protection seller”) to exchange the credit risk of an issuer (“reference obligation”) for a specified time period. The reference obligation may be one or more debt securities or an index of such securities. The Funds may be either the protection buyer or the protection seller. The protection buyer is obligated to pay the protection seller a stream of payments (“fees”) over the term of the contract, provided that no credit event, such as a default or a downgrade in credit rating, occurs on the reference obligation. The Funds may also make or receive upfront payments. If a credit event occurs, the protection seller must pay the protection buyer the difference between the agreed upon notional value and market value of the reference obligation. Market value in this case is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the value. The maximum potential amount of undiscounted future payments that a Fund as the protection seller could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement.

The notional amounts of credit default swaps are not recorded in the financial statements. Credit default swaps are marked-to-market daily. Fluctuations in the value of credit default swaps are recorded in the Statements of Operations as change in unrealized appreciation (depreciation) on swap agreements. Fees are accrued in accordance with the terms of the agreement and are recorded in the Statements of Operations as realized gain or loss when received or paid. Upfront fees paid or received by the Funds are recorded on the Statements of Assets and Liabilities as an asset or liability, respectively, and are amortized or accreted over the term of the agreement and recorded as realized gain or loss. Payments made or received by the Funds as a result of a credit event or termination of the agreement are recorded as realized gain or loss.

Credit default swaps are privately negotiated and traded between counterparties and, as such, are subject to the risk that a party to the agreement will not be able to meet its obligations. The Funds cover their net obligations under outstanding credit default swaps by segregating or earmarking liquid assets or cash.

There were no credit default swaps held by the Funds during the six months ended March 31, 2011.

g. Due to/from Brokers. Transactions and positions in forward foreign currency contracts and swap agreements are maintained and cleared by registered U.S. broker/dealers pursuant to customer agreements between the Fund and the various broker/dealers. Due to brokers’ balances in the Statements of Assets and Liabilities represent cash and securities received as collateral for forward foreign currency contracts. In certain circumstances the Funds’ use of cash and/or securities pledged as collateral is restricted by regulation or broker mandated limits.

h. 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, 2011 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.

i. 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 of items such as foreign currency transactions, defaulted bond adjustments, discount adjustments on inflation-protected securities, paydown gains and losses, premium amortization, reclassification of realized capital gain to ordinary income and return of capital and capital gain 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, securities lending collateral gain/loss adjustments, forward and futures contracts mark to market, defaulted bond interest, REIT basis adjustments, adjustments to inflation-protected securities and contingent payment debt instruments. 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, 2010 was as follows:


	2010 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Bond Fund	$	1,103,370,547	$	—	$	1,103,370,547
Fixed Income Fund		42,551,309		—		42,551,309
Global Bond Fund		71,257,098		—		71,257,098
Inflation Protected Securities Fund		490,596		—		490,596
Institutional High Income Fund		30,544,655		11,002		30,555,657
Intermediate Duration Bond Fund		1,296,283		—		1,296,283
Investment Grade Fixed Income Fund		27,602,054		—		27,602,054

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

As of September 30, 2010, the capital loss carryforwards and post-October losses were as follows:


Capital loss carryforward:	Bond Fund			Fixed Income Fund			Global Bond Fund			Inflation Protected Securities Fund

j. 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.

k. Delayed Delivery Commitments. The Funds may purchase securities, including those designated as TBAs in the Portfolio of Investments, for which delivery or payment will occur at a later date, beyond the normal settlement period. The price of the security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The security and the obligation to pay for it are recorded by the Funds at the time the commitment is entered into. The actual security that will be delivered to fulfill a TBA trade is not designated at the time of the trade. The security is “to be announced” 48 hours prior to the established trade settlement date. The value of

March 31, 2011 (Unaudited)

the security may vary with market fluctuations during the time before the Funds take delivery of the security. No interest accrues to the Funds until the transaction settles. When the Funds enter into such a transaction, collateral consisting of liquid securities or cash and cash equivalents is required to be segregated or earmarked at the custodian in an amount at least equal to the amount of the Funds’ commitment.

There were no delayed delivery securities held by the Funds as of March 31, 2011.

l. 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 may 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.

For the six months ended March 31, 2011, none of the Funds had loaned securities under this agreement.

m. 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.

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;

•

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, 2011, 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 used during the period include forward foreign currency contracts and futures 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. Certain Funds may enter into forward foreign currency exchange contracts for hedging purposes to protect the value of the Funds’ holdings of foreign securities. Certain 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, 2011, Global Bond Fund engaged in forward foreign currency transactions for hedging purposes and to gain exposure to foreign currencies.

The Funds are subject to the risk that changes in interest rates will affect the value of the Funds’ investments in fixed income securities. A Fund will be subject to increased interest rate risk to the extent that it invests in fixed-income securities with longer maturities or durations, as compared to investing in fixed-income securities with shorter maturities or durations. The Funds may use futures contracts to manage their duration in order to control interest rate risk without having to buy or sell portfolio securities. During the six months ended March 31, 2011, Global Bond Fund and Intermediate Duration Bond Fund used futures contracts in accordance with this objective.

Each Fund is party to agreements with counterparties that govern transactions in forward foreign currency contracts. The agreements contain credit-risk-related 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 features were to be triggered, the counterparties could request immediate settlement of open contracts at current fair value. As of March 31, 2011, there were no Funds that held derivative positions subject to credit-risk-related contingent features that were in a net liability position (unrealized depreciation) by counterparty.

Forward foreign currency contracts are subject to the risk that the counterparty will be unwilling or unable to meet its obligations under the contracts. The Funds have mitigated this risk by entering into master netting agreements with counterparties that allow the Fund and the counterparty to net amounts owed by each related to derivative contracts to one net amount payable by either the Fund or the counterparty. As of March 31, 2011, the maximum amount of loss that Global Bond Fund would incur if counterparties failed to meet their obligations, based on the value of derivative positions in an unrealized gain position as of period end, is $4,130,446 and the amount of loss that Global Bond Fund would incur after taking into account master netting arrangements is $1,723,027.

Counterparty risk is managed through the posting of collateral and, as a result, the risk of loss to a Fund from counterparty default should be limited to the extent a Fund is under collateralized. In addition to collateral requirements, the Funds also require counterparties to meet minimum credit quality requirements.

The following is a summary of derivative instruments for Global Bond Fund as of March 31, 2011:


Statements of Assets and Liabilities Caption	Foreign Exchange Contracts			Interest Rate Contracts
Assets
Unrealized appreciation on forward foreign currency contracts	$	4,130,446		$	—
Unrealized appreciation on futures contracts*		—			34,522
Liabilities
Unrealized depreciation on forward foreign currency contracts		(2,407,419	)		—

* Represents cumulative unrealized appreciation (depreciation) on futures contracts. Only the current day’s variation margin on futures contracts is reported within the Statements of Assets and Liabilities as receivable or payable for variation margin, as applicable. Variation margin as of Mach 31, 2011 was $0.

Transactions in derivative instruments for Global Bond Fund during the six months ended March 31, 2011 were as follows:


Statements of Operations Caption	Foreign Exchange Contracts		Interest Rate Contracts
Net Realized Gain (Loss) on:
Foreign currency transactions*	$	2,446,506	$	—

As the Funds value their derivatives at fair value and recognize changes in fair value through the Statements of Operations, they do not qualify for hedge accounting under authoritative guidance for derivative instruments. The Funds’ investments in derivatives may represent an economic hedge; however, they are considered to be non-hedge transactions for the purpose of these disclosures.

b. Service and Distribution Fees. Natixis Distributors, L.P. (“Natixis Distributors”), a wholly-owned subsidiary of Natixis US, has entered into a distribution agreement with the Trust. Pursuant to this agreement, Natixis Distributors serves as principal underwriter of the Funds of the Trust.

Pursuant to Rule 12b-1 under the 1940 Act, Bond Fund, Global Bond Fund, Inflation Protected Securities Fund and Intermediate Duration Bond Fund have adopted a Distribution Plan relating to each Fund’s Retail Class shares (the “Retail Class Plan”), and the Bond Fund has adopted a Distribution Plan relating to its Admin Class shares (the “Admin Class Plan”).

Under the 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, Bond 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 sales 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 Bond 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, 2011, the Funds paid the following service and distribution fees:


	Service Fees				Distribution Fees
Fund	Retail Class		Admin Class		Retail Class		Admin Class

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 to exceed what the Funds would have paid their 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, 2011, 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
Bond Fund	$	2,411,946	$	3,164,315	$	142,914

e. Trustees Fees and Expenses. The Trust does not pay any compensation directly to its officers or Trustees who are directors, officers or employees of Natixis Advisors, Natixis Distributors, Natixis US or their affiliates. The Chairperson of the Board receives a retainer fee at the annual rate of $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. 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.

7. Class Specific Expenses. For the six months ended March 31, 2011, the Funds paid the following class-specific transfer agent fees and expenses (including sub-transfer agent fees):

8. 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, 2011, none of the Funds had borrowings under these agreements.

9. Concentration of Risk. Each Fund’s investments in foreign securities are subject to foreign currency fluctuations, higher volatility than U.S. securities, varying degrees of regulation and limited liquidity. Greater political, economic, credit and information risks are also associated with foreign securities.

10. Concentration of Ownership. At March 31, 2011, Loomis Sayles Distributors, L.P. and Loomis Sayles Trust Co. LLC owned 262,588 shares, equal to 16.73% of Inflation Protected Securities Fund’s shares outstanding. At March 31, 2011, the Loomis Sayles Funded Pension Plan and Trust (“Pension Plan”) and the Loomis Sayles Employees’ Profit Sharing Retirement Plan (“Retirement Plan”) held shares of beneficial interest in the Funds as follows:


Fund	Pension Plan		Retirement Plan
Bond Fund		959,011		2,124,312
Global Bond Fund		—		483,918
Inflation Protected Securities Fund		—		273,472
Institutional High Income Fund		—		1,454,868
Intermediate Duration Bond Fund		—		88,153

From time to time, the Funds may have a concentration of several shareholders having a significant percentage of shares outstanding. Investment activities of these shareholders could have material impacts on the Funds. As of March 31, 2011, certain Funds had shareholders that held greater than 5% of the fund’s outstanding shares. Such ownership may be beneficially held by multiple individuals or entities other than the owner of record. The number of greater than 5% shareholders and the aggregate percentage of net assets represented by such ownership was as follows:


Fund	Number of Greater Than 5% Shareholders	Percentage of Ownership
Fixed Income Fund	3	19.07%
Global Bond Fund	1	11.45%
Inflation Protected Securities Fund	3	22.33%
Intermediate Duration Bond Fund	4	72.89%
Investment Grade Fixed Income Fund	3	22.40%
