Our stock selections in the financial services sector, which was overweighted relative to the Benchmark, accounted for the majority of the Fund's outperformance. In mid-October we began taking profits in some of the Fund's energy holdings, moving from a significant overweight to a close-to-neutral position. We used those profits to increase our holdings in the financial services sector. This swap helped performance, because the energy sector was weak during the period, while many of the Fund's financials stocks were strong. Although our financial services holdings are a diverse group, our primary exposure is to the capital markets sector (Moody's Corporation, Chicago Mercantile Exchange, IntercontinentalExchange) and to commercial real estate services companies (CB Richard Ellis Group). We believe the capital markets names we selected may show increasing profitability as electronic trading becomes more prevalent and the industry consolidates. We also think the real estate services companies we selected should benefit from a worldwide cyclical upturn in commercial leasing and from a secular increase in real estate investing. Given the relatively flat yield curve, we avoided investing in banks. Performance in the Fund's technology sector was broad-based, but driven primarily by company-specific fundamentals, with no broad theme or industry exposure leading the sector's outperformance. In particular, the Fund held strong performers in the semiconductor industry (Broadcom), Internet services (Akamai Technology) and communications equipment (F5 Networks). The Fund's healthcare sector also displayed broad strength during the period, with solid performance from biotech, health services and medical device companies. However, the two common themes were cost containment and therapeutic innovation. Our strategy is to invest in companies that we believe will show superior earnings growth, either because of company-specific events (e.g., a new product cycle) or because of increased operating leverage as the economic cycle unfolds. In addition, we have attempted to focus on a select number of high-confidence companies, industries, and sectors that we believe are undergoing a major transformation. Our biggest sector overweight remains financial services; in particular, we continue to focus on the demutualization of the stock and derivatives exchanges, which we think is an excellent example of transformational change. Two sectors--energy and materials and processing--had an overall negative impact on Fund performance during the period. In the energy sector, stock selection added value, but our trading around the core positions generated mixed results. For example, in the fourth calendar quarter of 2005 we reduced the Fund's emphasis on energy, moved to a neutral weighting, and locked in attractive gains. In January 2006 we moved back to an overweighted position just in time to participate in the sector's correction. Materials stocks also weakened during the period, following their strong performance in the third calendar quarter of 2005. Again, we did not time our buys and sells particularly well. The consumer discretionary segment remains the Fund's largest sector underweight. The headwinds to consumer spending--including rising interest rates, high energy prices and declining mortgage equity withdrawals--are well known and already discounted in share prices to some extent. Therefore, despite some near-term concerns, we continue to seek out attractive companies in this sector. 1 OUTLOOK The economy continues to grow at a healthy pace, and it seems poised to deliver significant potential earnings growth. This level of earnings, combined with dividend distributions, may keep the market in good shape. However, in the short run, investors' fixation with predicting the end of the rate-hike cycle casts a conservative blanket on the market. Daily and monthly economic data take on tremendous influence, making it difficult for stocks to gain traction. We remain conservative on both economic growth and inflation prospects, and look forward to a more neutral Federal Reserve policy.

Average annual total returns assume reinvestment of dividends and capital gain distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers and reimbursements, performance would be lower. (a) Cumulative performance is shown for the Institutional Class of shares. Performance of the Retail Class of shares would be lower due to higher fees. (b) The mountain chart is based on the initial investment minimum of $100,000 for the Institutional Class. (c) See page 11 for a description of the indexes. WHAT YOU SHOULD KNOW Small- and mid-cap stocks may be more volatile than larger, more established companies. The secondary market for these stocks may be less liquid, which could adversely impact the Fund's value. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than US standards. Growth funds involve increased risks, in part, because the value of the underlying securities is based on future expectations that may or may not be met. 2 FUND AND MANAGER REVIEW LOOMIS SAYLES SMALL CAP GROWTH FUND [PHOTO] JOHN SLAVIK Manager since April 2005 [PHOTO] Mark F.

Leading sectors included technology, financials and consumer discretionary--areas in which our stock selections drove performance. These sectors were home to the top three performers for the period. Although we generally build the Fund's sector positions from the bottom up, the Fund's weightings in technology and financials increased during the six-month period, while healthcare and producer durables decreased. We took profits in financial holding CB Richard Ellis Group, a commercial real estate broker and the Fund's top performer for the six months ended March 31, 2006. The company is benefiting from the commercial real estate cycle, which is still in a relatively early stage. In addition, the company's market-share gains and operating leverage have helped it post strong earnings and generate solid cash flow. Apparel company Guess, a consumer discretionary holding, also was among the leading performers for the six-month period. The company posted strong earnings growth due to the brand's re-emergence and to several management initiatives that have improved profitability. Technology holding Redback Networks, a communications equipment manufacturer, also was among the Fund's top three contributors to performance. The company increased its customer base with several large telecommunication companies that needed to upgrade their data and video-services networks. The utilities sector was the only area showing a negative absolute contribution to the Fund's six-month return. The lone utilities stock owned by the Fund during the period was Alamosa Holdings, a Sprint wireless service affiliate, which we sold. Although the stock increased significantly since we purchased it, it did give back a small part of these gains during the fourth quarter of 2005. Among individual holdings, Hudson Highland, SFBC and Universal American were the Fund's worst performers during the six-month period, and we sold each stock. Due to some customer concentration issues, the market has drastically reduced its earnings outlook for Hudson Highland, a staffing company. These earnings revisions severely weighed on the stock. SFBC, a clinical staffing company serving the pharmaceuticals industry, suffered stock setbacks when it announced a declining backlog. A federal investigation into one of the company's facilities also weakened the stock. Universal American, an insurance company we owned for its exposure to Medicare Part D, struggled when earnings faltered due to another business line. OUTLOOK Looking ahead, we believe the market has the potential to deliver returns in line with earnings growth. The economy continues to grow at a healthy rate, which may allow for brisk earnings growth. We think selected smaller companies have the potential to experience even faster 3 growth. This level of earnings, combined with dividend payments, may keep the market vital. In the near term, though, investors' fixation with predicting the end of the interest-rate-hike cycle may increase market volatility. With shorter-than-usual time horizons, investors are basing decisions on daily and monthly economic data. We remain conservative toward economic growth and inflation prospects, and we look forward to a more neutral Federal Reserve policy.

The secondary market for these stocks may be less liquid, which could adversely impact the Fund's value. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than US standards. Growth funds involve increased risks, in part, because the value of the underlying securities is based on future expectations that may or may not be met. 4 FUND AND MANAGER REVIEW LOOMIS SAYLES SMALL CAP VALUE FUND /s/ Joseph Katz Manager since January 2000 [PHOTO] Daniel Thelen Manager since April 2000 Manager since April 2000 FUND FACTS SYMBOL | Institutional: LSSCX; Retail: LSCRX; Admin: LSVAX 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 FUND INCEPTION DATE | 5/13/91 COMMENCEMENT OF OPERATIONS OF CLASS | Institutional: 5/13/91; Retail: 1/2/97; Admin; 1/2/98 EXPENSE RATIO | Institutional: 0.90%; Retail: 1.15%; Admin: 1.40% TOTAL NET ASSETS | $814.3 million PORTFOLIO REVIEW The Fund posted solid performance for the six-month period ended March 31, 2006, maintaining pace with its Benchmark, the Russell 2000 Value Index, in a market climate that strongly favored small-cap stocks. All sectors except utilities generated positive returns for the Fund. Our sector allocations were positive influences on relative performance, while stock selection was a slight negative. In particular, our technology and consumer discretionary stocks generally lagged the Benchmark. But good stock selection within the energy, basic materials and financial services sectors largely offset the negative influence of the laggards. Within financial services, we found strength in the credit card processing, consumer finance, and real estate investment trust (REIT) areas, as opposed to more traditional banks and insurance companies. For example, Wright Express Corp., which provides payment processing and information management services for vehicle fleets, and Advanta Corp., an issuer of business credit cards, were the Fund's top financial services holdings. Many basic materials companies continued to benefit from their ability to pass through higher costs of raw materials to end customers. A healthy commercial construction market also helped these companies. Chaparral Steel, a manufacturer of structural steel products and steel bars, was the Fund's top performer. Although the company has no formal Wall Street coverage yet, it has delivered very strong earnings during its short history as an independent entity. (Texas Industries spun it off in July 2005.) Chaparral clearly has benefited from the strong commercial construction environment and the ability to raise prices, as the steel supply remains relatively tight. The Fund's second-best performer was Live Nation, another recent spin-off. We added this producer and promoter of music concerts and theatrical shows shortly after Clear Channel Entertainment made it a separate entity. The overhang of stock caused by the spin-off resulted in a large number of shares available at an attractive valuation, and we were able to build a position before the stock rose sharply in the first calendar quarter of 2006. Live Nation has announced a number of initiatives to create shareholder value, including monetizing certain real estate assets and increasing the company's presence in ticket and concession sales. The Fund's utility stocks were marginally negative as a result of volatile prices in the natural gas market, which impacted a few of the Fund's holdings. Other lagging sectors included consumer staples and healthcare, as investors preferred more economically sensitive companies and sectors during the period. Two of the Fund's strongest performers for the first nine months of 2005 reversed course late in the calendar year, leading to disappointing six-month performance. In addition to suffering from the overall weakness in energy stocks, Energy Partners Ltd., an oil and natural gas exploration and production company, declined due to a modest shortfall in some of its exploration efforts and a delay in production growth stemming from the 2005 hurricane season. Hudson Highland Group, a professional staffing and executive recruiting firm, surprised investors with a late-December reduction in its fourth-quarter earnings forecast, after raising its forecast for the year in late October. We reduced the fund's position in Energy Partners and eliminated the position in Hudson Highland. OUTLOOK The economy continues to grow at a healthy pace, and it seems poised to deliver potentially solid earnings growth. We believe this level of earnings, combined with dividend distributions, may keep the market vital. In the short run, though, investors' fixation with predicting the end of the 5 rate-hike cycle casts a conservative blanket on the market. Daily and monthly economic data take on tremendous influence, making it difficult for stocks to gain traction. We remain conservative on both economic growth and inflation prospects, and look forward to a more neutral Federal Reserve policy. We will continue to emphasize companies that appear to be positioned for strong performance as the economic cycle matures. We believe capital spending trends should improve, driven by strong corporate balance sheets and healthy cash flow across some economic sectors. Therefore, we have increased the Fund's position in the producer durables sector and decreased exposure to consumer discretionary stocks, given the headwinds of higher energy prices and a diminishing stimulus from mortgage-refinance activity. After realizing solid gains from many basic materials companies, we have also trimmed these holdings because relative return prospects seem less attractive.

Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers and reimbursements, performance would be lower. (a) Performance shown for periods prior to the inception date of the Retail Class (12/31/96) and Admin Class (1/02/98) represents the performance of the Institutional Class of shares during the periods shown, adjusted to reflect the current levels of management and 12b-1 fees payable by the respective Classes. Since index performance data is not available coincident with the Fund's inception date, the beginning value of the index is the value as of the month end closest to the Fund's inception date. (b) The Lipper Small-Cap Core Funds Index performance data is not available prior to January 1, 1992. (c) See page 11 for a description of the indexes. (d) Cumulative performance is shown for the Institutional Class of shares. Performance of the Retail and Admin Classes would be lower due to higher fees and expenses. (e) The mountain chart is based on the initial investment minimum of $100,000 for the Institutional Class. WHAT YOU SHOULD KNOW Value stocks may fall out of favor with investors and underperform the overall equity market during any given period. Small- and mid-cap stocks may be more volatile than larger, more established companies. The secondary market for these stocks may be less liquid, which could adversely impact the Fund's value. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than US standards. 6 FUND AND MANAGER REVIEW LOOMIS SAYLES TAX-MANAGED EQUITY FUND [PHOTO] DAVID SOWERBY Manager since August 2005 [PHOTO] Mark Shank Manager since June 2003 FUND FACTS SYMBOL | LSCGX OBJECTIVE | Long-term capital growth STRATEGY | Invests at least 80% of net assets (plus any borrowings made for investment purposes) in equity securities and may invest in companies of any size; the Fund uses a tax-managed approach in an effort to minimize the effect of federal income tax FUND INCEPTION DATE | 10/1/95 FUND REGISTRATION DATE | 3/7/97 EXPENSE RATIO | 0.65% TOTAL NET ASSETS | $9.6 million PORTFOLIO REVIEW The Fund posted solid absolute and relative performance for the six-month period ended March 31, 2006. Strong stock selection in the industrials and technology sectors, along with our emphasis on materials (the best performing sector in absolute terms) accounted for the majority of the Fund's outperformance relative to its Benchmark, the Standard & Poor's 500 Index. Our strategy has been to overweight economically sensitive sectors of the market where we believe companies still have earnings leverage. Within these sectors, we focused on high-quality companies with accelerating business models. From an industry perspective, the financial and industrial sectors had the greatest positive impact on Fund performance, due to their large portfolio weightings and strong returns from the stocks we selected. The Fund's largest sectors included financial and industrial companies. Global investment services holding Goldman Sachs Group made the greatest contribution to performance. The company reported higher-than-expected earnings, primarily stemming from strong capital markets activity. We increased the Fund's weighting in the financials sector by adding to existing positions and establishing a new position in property casualty reinsurer Everest Re Group, Ltd. Within the industrials sector, energy services company GlobalSantaFe and Burlington Northern Santa Fe, a major railroad company, made the second- and third-greatest contributions to performance, respectively. Global SantaFe increased its future earnings estimates based on increased prices for its products and services. Burlington Northern benefited from better-than-expected earnings and continued economic growth. The technology sector also made strong contributions to the Fund's performance, with Cisco Systems and Harris Corp. realizing attractive six-month gains. The healthcare sector had the largest negative impact on the Fund's performance, primarily due to weak results from Kinetic Concepts and Guidant. Kinetic Concepts, which was among the greatest detractors to Fund performance, declined on competitive pressures. The Fund's energy sector also performed poorly for the period. In particular, the stock price of natural gas producer Devon Energy fell during the six-month period, along with natural gas prices. Other individual stocks that hurt performance included chip maker Intel, which declined in price on weaker-than-expected earnings, largely due to the company's loss of market share to rival Advanced Micro Devices. We sold Intel in January. OUTLOOK We believe the economy should continue to grow at a healthy pace, and it seems poised to deliver potentially strong earnings growth. In our view, this level of earnings, combined with dividend distributions, should keep the market strong. However, in the short run, investors' fixation with predicting the end of the rate-hike cycle casts a conservative blanket on the market. Daily and monthly economic data take on tremendous influence, making it difficult for stocks to gain traction. We remain conservative on both economic growth and inflation prospects, and look forward to a more neutral Federal Reserve policy. 7 AVERAGE ANNUAL TOTAL RETURNS PERIODS ENDED MARCH 31, 2006 SINCE

Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Performance data reflects certain fee waivers and reimbursements, without which, performance and rankings would be lower. Except as indicated in the table above, returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements, such as 401(k) plans, qualified plans, education savings accounts or individual retirement accounts. Under certain circumstances, the addition of the tax benefits from capital losses resulting from redemptions may cause the Return After Taxes on Distributions and Sale of Fund Shares to be greater than the Return After Taxes on Distributions or even the Return Before Taxes. (a) Shares of the Fund were registered for offer under the Securities Act of 1933 on March 7, 1997. In accordance with regulations, performance information is provided for the period beginning on March 7, 1997 ("Registration").

WHAT YOU SHOULD KNOW Growth funds involve increased risks, in part, because the value of the underlying securities is based on future expectations that may or may not be met. 8 FUND AND MANAGER REVIEW LOOMIS SAYLES VALUE FUND [PHOTO] ARTHUR BARRY Manager since July 2005 [PHOTO] James Carroll Manager since November 2002 /s/ Warren Koontz Manager since June 2000 FUND FACTS SYMBOL | LSGIX OBJECTIVE | Long-term growth of capital and income STRATEGY | Invests primarily in equity securities, including common stocks, convertible securities, and warrants; Fund invests primarily in medium- and large-sized companies FUND INCEPTION DATE | 5/13/91 EXPENSE RATIO | 0.85% TOTAL NET ASSETS | $41.7 million PORTFOLIO REVIEW The Fund significantly outpaced its benchmark, the Russell 1000 Value Index, for the six months ended March 31, 2006. Throughout the period, we maintained our disciplined, bottom-up approach to stock selection, which resulted in solid performance. Financials and industrials were the Fund's best-performing sectors during the period. Market-sensitive names, including Lehman Brothers and Merrill Lynch, generated strong results. These companies benefited from merger-and-acquisition activity and from better-than-expected earnings reports. Our well-diversified industrials sector exhibited broad-based strength, with most holdings making positive contributions to performance. In particular, we focused on companies we believed to be well managed, with strong cash generation and good exposure to this late phase of the economic cycle. ABB Ltd. was the Fund's top performer, benefiting from the power industry's need for increased infrastructure. Burlington Northern Santa Fe was the Fund's second-best individual performer, advancing on the company's consistently positive track record, coupled with a positive outlook for the transportation markets in 2006. Other individual stocks that performed well for the Fund included two energy companies, GlobalSantaFe and Occidental Petroleum, and two consumer companies, Office Depot and TJX. In addition, BellSouth Corp. gained on the announcement of its merger with AT&T. The combined company will create the largest US telecommunication provider in many regions. Economies of scale should also help the new company benefit from local synergies and potentially enjoy increased purchasing power. Utilities was the only market sector that detracted from the Fund's relative performance. Recently, rising interest rates and falling commodities prices took a toll on utilities stocks. Fundamentals for the energy sector remain favorable, in our opinion, but some profit-taking seemed to be warranted, so we trimmed the Fund's energy weighting. Conoco, Exxon Mobil and Chevron all had a slightly negative impact on Fund performance and we eliminated Conoco and Chevron. These integrated energy stocks underperformed the broader benchmarks throughout the six-month period, as aggressive investors continued to rotate into more leveraged parts of the sector, including oil services and independent producers. The market has become increasingly sensitized to the possibility that high commodity prices might lead to moderating demand. This has led to weakness in the leveraged companies. Currently, we believe stocks of selected integrated energy companies are attractively priced, and the companies are returning substantial cash flow to shareholders while offering defensive potential if oil and gas prices recede. 9 OUTLOOK The economy continues to grow at a healthy pace, and it seems poised for solid earnings growth. Especially if this is combined with rising dividend distributions, we believe the market should be in good shape. In the short run, though, investors' fixation with predicting the end of the rate-hike cycle casts a conservative blanket on the market. Daily and monthly economic data take on tremendous influence, making it difficult for stocks to gain traction. We remain conservative on both economic growth and inflation prospects, and look forward to a more neutral Federal Reserve policy.

past performance and cannot guarantee future results. Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers and reimbursements, performance would be lower. (a) Index performance data is not available coincident with the Fund's inception date; comparative performance is presented from the month end closest to the Fund's inception date. (b) See page 11 for a description of the indexes. (c) The mountain chart is based on the Fund's minimum initial investment of $100,000. WHAT YOU SHOULD KNOW Value stocks may fall out of favor with investors and underperform the overall equity market during any given period. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than US standards. 10 ADDITIONAL INFORMATION INDEX DEFINITIONS Indexes are unmanaged and do not have expenses that affect results, unlike mutual funds. Index returns are adjusted for the reinvestment of capital gain distributions and income dividends. It is not possible to invest directly in an index.

AFTER-TAX RETURNS After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements, such as 401(k) plans, qualified plans, education savings accounts or individual retirement accounts. Under certain circumstances, the addition of the tax benefits from capital losses resulting from redemptions may cause the return after taxes on distributions and sale of fund shares to be greater than the return after taxes on distribution or even the return before taxes. PROXY VOTING INFORMATION 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 SEC's website at www.sec.gov. Information about how the Funds voted proxies relating to portfolio securities during the 12 months ended June 30, 2005 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 YOUR FUND'S EXPENSES As a mutual fund shareholder you incur two types of costs: (1) transaction costs, including redemption fees and certain exchange fees; and (2) ongoing costs, including management fees, distribution and/or service fees (12b-1 fees), and other Fund expenses. These costs are described in more detail in the Funds' prospectus. The examples below are intended to help you understand the ongoing costs of investing in the Funds and help you compare these with the ongoing costs of investing in other mutual funds. 11 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, 2005 through March 31, 2006. 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.

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 investment management company. Each Declaration of Trust permits the Board of Trustees to authorize the issuance of an unlimited number of shares of the Trusts in multiple series (individually, a "Fund" and collectively, the "Funds"). Shares of Loomis Sayles Tax-Managed Equity Fund were first registered under the Securities Act of 1933 (the "1933 Act") effective March 7, 1997 (subsequent to its commencement of investment operations). Information presented in these financial statements pertains to certain equity funds of the Trusts; the financial statements for the remaining equity funds and the fixed income funds are presented in separate reports. The following 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 Aggressive Growth Fund (the "Aggressive Growth Fund") Loomis Sayles Small Cap Growth Fund (the "Small Cap Growth Fund") Loomis Sayles Tax-Managed Equity Fund (the "Tax-Managed Equity Fund") Loomis Sayles Value Fund (the "Value Fund") Each Fund offers Institutional Class Shares. Aggressive Growth Fund, Small Cap Growth Fund and Small Cap Value Fund also offer 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 can not 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 applicable to such Class), and votes as a Class only with respect to its own Rule 12b-1 Plan. Shares of each Class would receive their pro rata share of the net assets of a Fund if the Fund were liquidated. The Trustees approve separate dividends from net investment income on each Class of shares. 2. SIGNIFICANT ACCOUNTING POLICIES. The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements. The Funds' financial statements are prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of management estimates that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. SECURITY VALUATION. Equity securities for which market quotations are readily available are valued at market value, as reported by pricing services recommended by the investment adviser's pricing committee and approved by the Board of Trustees. Such pricing services generally use the security's last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ National Market are valued at the NASDAQ Official Closing Price ("NOCP"), or if lacking an NOCP, at the most recent bid quotation on the NASDAQ National Market. Debt securities for which market quotations are readily available (other than short-term obligations with a remaining maturity of less than 60 days) are generally valued at market value, as reported by pricing services recommended by the investment adviser's pricing committee and approved by the Board of Trustees. Such pricing services generally use the most recent bid prices in the principal market in which such securities are normally traded. 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. Short-term obligations with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available (including restricted securities, if any) are valued at fair value as determined in good faith by the Funds' investment adviser using consistently applied procedures under the general supervision of the Board of Trustees. Investments in other open-end investment companies are valued at the net asset value each day. The Funds may hold securities traded in foreign markets. Foreign securities are valued at the market price in the foreign market. However, if events occurring after the close of the foreign market (but before the close of regular trading on the New York Stock Exchange) are believed to materially affect the value of those securities, such securities are fair valued pursuant to procedures approved by the Board of Trustees. When fair valuing equity securities, a Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Fund calculates its net asset value. B. SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME. Security transactions are accounted for on trade date. Dividend income is recorded on ex-dividend date, or in the case of certain foreign securities, as soon thereafter as the Fund is notified, and interest 47 income is recorded on an accrual basis. Interest income is increased by the accretion of discount and decreased by the amortization of premium. Investment income is recorded net of foreign taxes withheld when applicable. The Funds estimate the components of distributions received from Real Estate Investment Trusts (REITs). In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. Investment income and realized and unrealized gains and losses are allocated on a pro rata basis to each class based on 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 US dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than US dollars are translated into US 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 arising from changes in market prices of the 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 US 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, 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. Each Fund may purchase investments of foreign issuers. Investing in securities of foreign issuers involves special risks and considerations not typically associated with investing in US companies and securities of the US government. These risks include revaluation of currencies and the risk of appropriation. Moreover, the markets for securities of many foreign issuers may be less liquid and the prices of such securities may be more volatile than those of comparable US companies and the US government. D. FORWARD FOREIGN CURRENCY CONTRACTS. Each Fund may enter into forward foreign currency exchange contracts. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell are used to hedge a Fund's investments against currency fluctuation. Also, a contract to buy or sell can offset a previous contract. These contracts involve market risk in excess of the unrealized gain or loss reflected in the Fund's Statement of Assets and Liabilities. The US 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. All contracts are "marked-to-market" daily at the applicable exchange rates and any 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 US dollar. At March 31, 2006, there were no open forward currency contracts. E. FEDERAL AND FOREIGN INCOME TAXES. The Trusts treat each Fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Accordingly, no provision for federal income tax has been made. 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. F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on ex-dividend date. The timing and characterization of certain income and capital gain distributions are determined 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 distributions from real estate investment trusts, net operating losses, non-deductible expenses, foreign currency transactions, gains realized from passive foreign investment companies and redemptions in kind. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts. Distributions from net investment income and short-term capital gains are considered to be ordinary income for tax purposes. 48 NOTES TO FINANCIAL STATEMENTS - CONTINUED MARCH 31, 2006 (UNAUDITED) The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2005 was as follows: 2005 DISTRIBUTIONS PAID FROM: ------------------------------------- ORDINARY LONG-TERM INCOME CAPITAL GAINS TOTAL ----------- ------------- ----------- Aggressive Growth Fund $ 498,778 $ -- $ 498,778 Small Cap Growth Fund -- -- -- Small Cap Value Fund 24,071,753 37,569,886 61,641,639 Tax-Managed Equity Fund 23,811 -- 23,811 Value Fund 524,122 -- 524,122 As of September 30, 2005, the capital loss carryforwards were as follows: AGGRESSIVE SMALL CAP SMALL CAP TAX-MANAGED CAPITAL LOSS CARRYFORWARD GROWTH FUND GROWTH FUND VALUE FUND EQUITY FUND VALUE FUND - ------------------------- ------------- ------------- ---------- ----------- ---------- Expires September 30, 2009 $ -- $ -- $-- $ (214,505) $-- Expires September 30, 2010 (79,794,012) (145,381,318) -- (2,177,191) -- Expires September 30, 2011 (21,142,388) (59,283,040) -- (1,662,157) -- Expires September 30, 2012 -- -- -- (110,150) -- Expires September 30, 2013 -- -- -- (17,395) -- ------------- ------------- ---------- ----------- ---------- Total capital loss carryforward $(100,936,400) $(204,664,358) $-- $(4,181,398) $-- ------------- ------------- ---------- ----------- ---------- G. REPURCHASE AGREEMENTS. Each Fund, through its custodian, receives delivery of the underlying securities collateralizing repurchase agreements. It is each Fund's policy that the market value of the collateral be at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party arrangements whereby the collateral is held at the custodian bank in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty including possible delays or restrictions upon a Fund's ability to dispose of the underlying securities. H. SECURITIES LENDING. The Funds have entered into an agreement with State Street Bank and Trust Company ("State Street Bank"), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value of the loaned international equity or domestic securities, respectively, when the loan is initiated. Thereafter, the value of the collateral must remain at 102% of the market value of loaned securities for US equities and US corporate debt; at least 105% of the market value of loaned securities for non-US equities; and at least 100% of the market value of loaned securities for US government and agency securities, sovereign debt issued by non-US governments and non-US 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. The market value of securities on loan to borrowers and the value of collateral held by the Funds with respect to such loans at March 31, 2006, were as follows: MARKET VALUE VALUE OF FUND ON LOAN COLLATERAL - ---- ------------ ------------ Aggressive Growth Fund $ 12,029,531 $ 12,115,232 Small Cap Growth Fund 6,169,083 6,265,097 Small Cap Value Fund 196,745,513 200,515,426 Tax-Managed Fund -- -- Value Fund 2,461,946 2,530,770 I. INDEMNIFICATIONS. Under the Funds' organizational documents, its officers and Trustees are indemnified against certain liability 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 Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote. 49 3. PURCHASES AND SALES OF SECURITIES. For the six months ended March 31, 2006, purchases and sales of securities (excluding short-term investments and US Government/Agency Securities) were as follows: FUND PURCHASES SALES - ---- ------------ ------------ Aggressive Growth Fund $ 45,939,509 $ 54,602,191 Small Cap Growth Fund 13,997,043 10,848,162 Small Cap Value Fund 231,948,097 238,009,238 Tax-Managed Equity Fund 2,865,488 3,139,643 Value Fund 7,191,724 7,182,146 4.

These undertakings are in effect until the date indicated above and will be reevaluated on an annual basis. Loomis Sayles is permitted to recover expenses it has borne under the expense limitation agreement (whether through reduction of its management fees or otherwise) in later periods to the extent the Funds' expenses fall below the expense limits, provided, however, that the Funds are not obligated to pay such deferred fees more than one year after the end of the fiscal year in which the fee was deferred. 50 NOTES TO FINANCIAL STATEMENTS - CONTINUED MARCH 31, 2006 (UNAUDITED) At March 31, 2006, the amounts subject to possible reimbursement under the expense limitation agreements were as follows: EXPENSES SUBJECT TO EXPENSES SUBJECT TO POSSIBLE POSSIBLE REIMBURSEMENT UNTIL REIMBURSEMENT UNTIL FUND SEPTEMBER 30, 2006 SEPTEMBER 30, 2007 - ---- ------------------- ------------------- Aggressive Growth Fund $116,730 $ 62,961 Small Cap Growth Fund 151,644 63,273 Small Cap Value Fund 189,817 132,068 Tax-Managed Fund 106,971 41,470 Value Fund 26,275 6,081 Certain officers and employees of Loomis Sayles are also officers or Trustees of the Trusts.

B. ADMINISTRATIVE FEES. IXIS Asset Management Advisors, L.P. ("IXIS Advisors") provides certain administrative services to the Funds and has subcontracted with State Street Bank to serve as sub-administrator. Pursuant to the agreement between the Trusts, IXIS Advisor Funds Trust I, IXIS Advisor Funds Trust II, IXIS Advisor Funds Trust III, IXIS Advisor Funds Trust IV and IXIS Cash Management Trust ("IXIS Advisor Funds Trusts")(collectively, the "Trusts") and IXIS Advisors, each Fund paid IXIS Advisors its pro rata portion of a group fee for these services representing the higher amount based on the following calculations: (1)Percentage of Average Daily Net Assets FIRST NEXT OVER $5 BILLION $5 BILLION $10 BILLION ---------- ---------- ----------- 0.0675% 0.0625% 0.0500% or (2)Each Fund's pro rata portion, allocated based on the combined assets of the Trusts and the IXIS Advisors Funds Trusts, of the annual aggregate minimum fee of $5 million.

SERVICE AND DISTRIBUTION FEES. The Trusts have entered into a distribution agreement with IXIS Asset Management Distributors, L.P. ("IXIS Distributors"), a wholly owned subsidiary of IXIS US Group. Pursuant to this agreement, IXIS Distributors serves as principal underwriter of the various Funds of the Trusts except for Loomis Sayles Investment Grade Bond Fund--Class J. Pursuant to Rule 12b-1 under the 1940 Act, Aggressive Growth Fund, Small Cap Growth Fund and Small Cap Value Fund have adopted Distribution Plans relating to each Fund's Retail Class shares (the "Retail Class Plan") and Small Cap Value Fund has adopted a separate Distribution Plan relating to Admin Class shares (the "Admin Class Plan"). Under the respective Retail Class and Admin Class Plans, each Fund pays IXIS 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 Retail Class and Admin Class Shares, as 51 reimbursement for expenses incurred by IXIS Distributors in providing personal services to investors in Retail Class and Admin Class Shares and/or maintenance of shareholder accounts. In addition, the Admin Class shares of the Small Cap Value Fund may pay a shareholder service fee, at an annual rate not to exceed 0.25% of the average daily net assets attributable to Admin Class shares, to securities dealers or financial intermediaries for providing personal service and account maintenance for their customers who hold such shares. D. TRUSTEES FEES AND EXPENSES. The Funds do not pay any compensation directly to its officers or Trustees who are directors, officers or employees of IXIS Advisors, IXIS Distributors, IXIS US Group, Loomis Sayles or their affiliates. The Chairperson of the Board receives a retainer fee at the annual rate of $200,000. The Chairperson does not receive any meeting attendance fees for Board of Trustees meetings or committee meetings that she attends. Each independent Trustee (other than the Chairperson) receives, in the aggregate, a retainer fee at the annual rate of $55,000. Each independent Trustee also receives a meeting attendance fee of $6,000 for each meeting of the Board of Trustees that he or she attends in person and $3,000 for each meeting of the Board of Trustees that he or she attends telephonically. In addition, each committee chairman receives an additional retainer fee at the annual rate of $10,000. Each committee member receives $4,000 or $5,000 for each Contract and Governance or Audit Committee meeting, respectively, that he or she attends in person and $2,000 or $2,500 for each Contract and Governance or Audit Committee meeting, respectively, that he or she attends telephonically. These fees are allocated among the funds in the Trusts based on a formula that takes into account, among other factors, the relative net assets of each fund. Trustees are reimbursed for travel expenses in connection with attendance at meetings. Prior to November 18, 2005, the Trusts had co-chairmen of the Board. Prior to October 1, 2005, each independent Trustee received, in the aggregate, a retainer fee at the annual rate of $50,000 and meeting attendance fees of $5,000 for each meeting of the Board of Trustees that he or she attended. The co-chairmen of the Board each received an additional annual retainer of $25,000. Each committee chairman received an additional retainer fee at the annual rate of $7,000. Each committee member received $3,750 for each committee meeting that he or she attended. In addition, during the period October 1, 2005 to November 18, 2005, each co-chairman received an additional one-time payment of $25,000 as compensation for their services as chairmen. Prior to January 1, 2006, each committee member was compensated $4,000 for each Audit Committee meeting that he or she attended in person and $2,000 for such meeting he or she attended telephonically. A deferred compensation plan (the "Plan") is available to the Trustees on a voluntary basis. Each participating Trustee will receive an amount equal to the value that such deferred compensation would have been had it been invested in a designated fund or certain other funds of the Trusts on the normal payment date. Deferred amounts remain in the Funds until distributed in accordance with the Plan. Additionally, the Board of Trustees has approved the use of the Funds' assets to pay their portion of the annual salary for 2005 of an employee at IXIS Advisors who supports the Funds' Chief Compliance Officer. For the period October 1, 2005 through December 31, 2005, each Fund's portion of such expense was approximately $575. E. REDEMPTION FEES. Shareholders of Small Cap Growth Fund and Small Cap Value Fund will be charged a 2% redemption fee if they redeem, including redeeming by exchange, any class of shares of these Funds within 60 days of their acquisition (including acquisition by exchange). The redemption fee is intended to offset the costs to the Funds of short-term trading, such as portfolio transaction and market impact costs associated with redemption activity and administrative costs associated with processing redemptions. The redemption fee is deducted from the shareholder's redemption or exchange proceeds and is paid to the Fund. The "first-in, first-out" (FIFO) method is used to determine the holding period of redeemed or exchanged shares, which means that if shares were acquired on different days, the shares acquired first will be redeemed or exchanged first for purposes of determining whether the redemption fee applies. A new holding period begins with each purchase or exchange. These fees are accounted for as an addition to paid-in capital and are presented on the Statements of Changes in Net Assets. 5. LINE OF CREDIT. Each Fund, together with certain other Funds of the Trusts, participates in a $75 million committed line of credit provided by State Street Bank. Advances under the line are taken primarily for emergency purposes. Interest is charged to a Fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a Fund is charged its pro rata portion of a facility fee equal to 0.09% per annum on the unused portion of the line of credit. For the period ended March 31, 2006, the Funds had no borrowing under this agreement. 6. BROKERAGE COMMISSION RECAPTURE. Each Fund has entered into agreements with certain brokers whereby the brokers will rebate a portion of brokerage commissions. All amounts rebated by the brokers are returned to the Funds under such agreements and are 52 NOTES TO FINANCIAL STATEMENTS - CONTINUED MARCH 31, 2006 (UNAUDITED) included in realized gains in the Statements of Operations. For the six months ended March 31, 2006, amounts rebated under these agreements were as follows: FUND REBATES - ---- ------- Aggressive Growth Fund $12,847 Small Cap Growth Fund 1,925 Small Cap Value Fund 48,650 Tax-Managed Equity 870 7. SHAREHOLDERS. At March 31, 2006, Loomis Sayles owned 259,319 shares, equating to 26.5% of Tax-Managed Equity Fund shares outstanding.

income and capital appreciation STRATEGY | Invests primarily in investment-grade fixed-income securities, although it may invest up to 35% of assets in lower rated fixed-income securities and up to 20% of its assets in preferred stocks. FUND INCEPTION DATE | 5/16/91 COMMENCEMENT OF OPERATIONS OF CLASS | Institutional: 5/16/91; Retail: 1/2/97; Admin: 1/2/98 EXPENSE RATIO | Institutional: 0.75%; Retail: 1.00%; Admin: 1.25% TOTAL NET ASSETS | $5,186.1 million PORTFOLIO REVIEW Once again, the Fund's outperformance relative to its Benchmark, the Lehman US Government/Credit Index, was due to our out-of-Benchmark strategies. In particular, the Fund's investments in high yield, convertible and foreign securities (none of which is represented in the Benchmark) had the most positive impact on Fund performance for the six-month period. Robust earnings, continued economic growth and a low rate of defaults boosted the high yield and convertible bond sectors. Among foreign securities, strong global economic growth and ongoing trade surpluses among certain Latin American and Pacific Rim countries helped performance. The strongest international performers included Fund holdings in Thailand, South Korea, Indonesia and Singapore. Continued trade surpluses and economic expansion in the Pacific Rim region helped the performance of these securities. In addition, Brazilian investments posted strong results due to the country's ongoing trade surpluses, which were fueled by the export of raw materials. Certain investments in the Mexican peso also performed well, primarily as a result of falling interest rates in Mexico during the fourth calendar quarter of 2005. Among industries, telecommunications, airline and pharmaceutical bonds generated strong performance for the Fund. The ongoing economic expansion combined with industry consolidation created a favorable climate for telecom bonds, particularly within the high yield and convertible sectors. Certain bonds in the pharmaceutical industry benefited from favorable product distribution, while select airline holdings advanced because the underlying companies benefited from continued high traffic with reduced capacity. In terms of performance detractors, select supranational holdings lagged for the period as a result of their exposure to the currencies of New Zealand and Australia. The market's increased attention to rising current account deficits in these countries helped push currency values down. The Fund maintains a "barbell" structure, with shorter-duration holdings concentrated in Treasury securities at one end of the spectrum, and longer-duration holdings in high yield issues at the other. This structure helps mute the impact of rising Treasury rates while helping to capture yield advantages among longer-term, high yield issues, which typically are not as adversely affected by rising rates. Throughout the six-month period, the Fund's average duration lengthened modestly, from 4.5 years to 4.9 years, due to our purchase of high yield bonds with longer-durations and convertible issues. OUTLOOK We believe the downside risk to bonds is lower now, because the market may be closer to seeing a peak in the federal funds rate and yields in general. Volatility may arise over the near term, as investors scour every bit of data in an effort to determine when the Federal Reserve will stop raising interest rates. We believe any spike in 1 rates may be short-lived as the market anticipates slower economic growth ahead. Also serving as a cap on rates, demand for US bonds seems likely to remain strong if the United States continues to be a "higher yield" country, despite the gains in yields globally. Investors in corporate bonds are faced with tight spread levels that could widen slightly. Nevertheless, the corporate market could outperform Treasuries by a small margin, given still-healthy profit growth in a supportive economic environment. We continue to find attractive opportunities in high yield bonds, but we remain somewhat cautious due to stretched valuations. We view this as a good time to reduce certain high yield exposures and look for opportunities to move back into the market at a later date, when spreads may be wider.

quoted reflects past performance and cannot guarantee future results. Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month-end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on Fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers, performance would be lower. (a) Inception date of the Institutional, Retail and Admin Classes of shares are May 16, 1991, December 31, 1996 and January 2, 1998, respectively. (b) The mountain chart is based on the initial investment minimum of $100,000 for the Institutional Class. (c) Performance shown for periods prior to the inception date of the Retail Class and the Admin Class represents the performance of the Institutional Class during the periods shown, adjusted to reflect the current levels of management and 12b-1 fees payable by the respective classes of shares. (d) See page 15 for a description of the indexes. Index performance data is not available coincident with the Fund's inception date, the beginning value of the index is the value as of the month end closest to the Fund's inception date. (e) Cumulative performance is shown for the Institutional Class of shares. Performance of the Retail and Admin Classes would be lower, due to higher fees. WHAT YOU SHOULD KNOW High-yield securities are subject to a high degree of market and credit risk. The secondary market for these securities may lack liquidity which may adversely affect the value of the fund. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets.

In particular, our security selections within the emerging markets, high yield and international sectors--sectors that are not represented in the Benchmark--helped generate the majority of the Fund's relative performance advantage. Tighter yield spreads in the US bond market caused investors to seek higher yields in the below investment grade sector and outside the United States. The Fund's high yield, emerging market and international bond holdings benefited from this trend. Outside the United States, improving fundamentals and increased global demand for commodities also helped emerging market and international bonds. Convertible securities and short-duration Canadian bonds also were positive performance drivers. US government agency securities performed poorly versus other sectors within the Fund, which detracted from its six-month performance. Yield-curve positioning was the primary culprit within this sector. From a country perspective, Brazil, the Philippines and the United States were the most positive performers. Brazil and the Philippines performed well as a result of improving fundamentals and favorable factors related to our specific security selections. Our strong weighting in the United States and positive performance from our domestic high yield selections were positives for the Fund. Securities from New Zealand and Sweden detracted slightly from performance. In terms of industries, the Fund realized the greatest positive performance from communications, sovereign issues and technology. The government-sponsored, finance and basic industries segments detracted the most from relative performance. In each case, issue-specific factors drove the results. The Fund remains positioned in a "barbell" fashion, in an attempt to limit interest rate risk. Overall, the Fund maintains a slightly defensive slant, with a shorter duration than the Benchmark. OUTLOOK We believe the downside risk to bonds is lower now, because the market is closer to seeing the peak in the federal funds rate and yields in general. Volatility may arise over the near term, as investors scour every bit of data in an effort to determine when the Federal Reserve will stop raising interest rates. We believe any spike in rates may be short-lived as the market anticipates slower economic growth ahead. Also serving as a cap on rates, demand for US bonds seems likely to stay strong, as the United States remains a "higher yield" country, despite the global rise in interest rates. Corporate investors are faced with tight spread levels that could widen slightly. Nevertheless, the corporate market may outperform Treasuries by a small margin, given still-healthy profit growth in a supportive economic environment. With respect to the high yield market, we continue to find attractive opportunities, but we remain somewhat cautious due to stretched valuations. We view this as a good time to reduce certain high yield exposures and look for opportunities to move back into the market at a later date when spreads are wider. 3 AVERAGE ANNUAL TOTAL RETURNS

Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers, performance would be lower. (a) Shares of the Fund were registered for offer and sale under the Securities Act of 1933 on March 7, 1997. In accordance with regulations, performance information is provided for the period beginning on March 7, 1997 ("Registration"). Performance from inception is also provided for the convenience of our long-term shareholders. Since index performance data is not available coincident with the Fund's inception and registration dates, comparative performance is presented from the month end closest to the Fund's inception and registration dates.

WHAT YOU SHOULD KNOW High yield securities are subject to a high degree of market and credit risk. The secondary market for these securities may lack liquidity which may adversely affect the value of the fund. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than those of the US. Securities issued by US government agencies are not issued, and may not be guaranteed by the US government. 4 FUND AND MANAGER REVIEW LOOMIS SAYLES GLOBAL BOND FUND [PHOTO] Ken Buntrock Manager since September 2000 [PHOTO] David Rolley Manager since September 2000 Manager since September 2000 FUND FACTS SYMBOL | Institutional: LSGBX; Retail: 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-rated fixed-income securities FUND INCEPTION DATE | 5/10/91 COMMENCEMENT OF OPERATIONS OF CLASS | Institutional: 5/10/91; Retail: 1/2/97 EXPENSE RATIO | Institutional: 0.75%; Retail: 1.00% TOTAL NET ASSETS | $1,060.7 million PORTFOLIO REVIEW Emerging market issues, particularly those denominated in local currencies, were the top performers for the six months ended March 31, 2006. Specifically, currency-linked notes in the Indonesian rupiah and Brazilian real issued by supranational entities and US or British commercial banks led the way and helped the Fund outperform its Benchmark, the Lehman Global Aggregate Bond Index. The high yield market posted strong performance in the final three months of the period. In particular, bonds issued by Qwest, Lucent Technologies and Albertson's posted strong returns. Yen-denominated securities of high-quality names were among the worst-performing securities; a weak yen and dramatically rising bond yields were responsible. We also maintained a defensive duration strategy during the period, which had a positive influence on the Fund's relative performance. Most major market bond yields dramatically increased, particularly in the January-to-March period, and our shorter duration helped the Fund's performance. Specifically, our short duration position in the Japanese yen paid off toward the end of the period, as yen yields increased dramatically after the bank of Japan announced the end of its accommodative monetary policy stance. Our country strategy, which included overweighted positions in Australian, New Zealand, British, Norwegian and Swedish bond markets, also was effective, primarily due to positive local-market returns. In addition, the Fund was underweighted in the negative-performing markets of the euro, US dollar and Japanese yen. Our strategy of maintaining overweighted positions in non-yen Asian currencies paid off handsomely, as these currencies advanced against the US dollar. The Brazilian real and the Mexican peso also posted positive currency performance. The Fund's modest overweight in the British pound and in Swedish krona detracted from performance, both on a relative and absolute basis, while our Benchmark exposure in yen hurt absolute performance as that currency depreciated. OUTLOOK Global economic growth prospects remain upbeat, with Asia leading the pack. Europe, particularly Germany, is benefiting from rising consumer and business confidence, and in the United States the first-quarter growth in the Gross Domestic Product is forecast to be vigorous, although it may slow to a slower, but still respectable growth rate for the balance of the year. The markets seem to expect continued tightening by key monetary authorities, including the US Federal Reserve Board, the European Central Bank and the Bank of Japan. But an end to the tightening mode appears within reach in the United States. We are keeping duration significantly shorter than the Benchmark in the yen, but only modestly shorter in the euro. We have been gradually increasing US dollar duration and are comfortable with the current Benchmark level in this market. Our overweight position in non-yen Asian currencies has been successful and remains in place. 5 In Europe, we have a constructive outlook for the Swedish and the Norwegian krone. We have been hedging the Fund's exposure to the New Zealand and Australian dollars, but the recent sell-off in these markets may open the door for an opportunistic removal of the currency hedges. We are maintaining select emerging market local currency and corporate positions, but event risks remain a concern. For example, leveraged buyouts, mergers and acquisitions, or other shareholder friendly actions could negatively affect already tight corporate spread levels.

The secondary market for these securities may lack liquidity, which may adversely affect the value of these securities and that of the Fund. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than those of the US Securities issued by US government agencies are not issued, and may not be guaranteed by the US government. 6 FUND AND MANAGER REVIEW LOOMIS SAYLES INFLATION PROTECTED SECURITIES FUND [PHOTO] John Hyll Manager since January 2003 Manager since January 2003 [PHOTO] Cliff Rowe Manager since January 2003 Manager since January 2003 FUND FACTS SYMBOL | LSGSX OBJECTIVE | High total investment return through a combination of current income and capital appreciation STRATEGY | Invests primarily in inflation-protected securities with emphasis on debt securities issued by the U.S. Treasury FUND INCEPTION DATE | 5/21/91 EXPENSE RATIO | 0.40% TOTAL NET ASSETS | $9.3 million PORTFOLIO REVIEW The Treasury market struggled during the six months ended March 31, 2006. During this period, interest rates increased as the Federal Reserve continued to raise rates as inflation expectations remained a concern. This environment led to a negative total return for the Fund, although it was in line with its Benchmark, the Lehman US Treasury Inflation Protected Securities Index, for the six-month period. Yields were driven higher by a rebounding economy, record Treasury issuance, and Fed Reserve tightening. Economic activity picked up after a slow fourth quarter, as evidenced by robust retail sales and payroll gains. Japan and Euroland seemed to join the party as well, with signs of stronger sustainable growth in those areas. The 30-year Treasury bond came out of retirement to help finance the burgeoning federal deficit, while Federal Reserve Chairman Greenspan went into retirement. Fear that the new Chairman might push rates up more aggressively helped push the 10-year Treasury yield up by quarter-end. Our outlook calls for a further hike to 5.25% and reflects the recent combination of strong economic data, buoyant stock prices, record gold prices, and robust growth outside of the US. However, risks of a pause have increased as the Fed has told us this (Bernanke, Yellen) and oil, confidence, or housing could produce a sharper than expected slowdown. Bond yields may be near a cycle peak. 2007 GDP appears reasonably strong, while headline inflation is expected to decline, and we see this as permitting a modest drop in bond yields from recent levels. Foreign yields have risen in line with US yields. The dollar, however, has recently weakened sharply, which is borderline bearish for bonds. The shape of the curve forecast implies modest Fed easing beyond the forecast horizon. Given our interest rate outlook, we have positioned the Fund for the possibility of lower interest rates. Unfortunately, during this period lower rates did not materialize and this did hurt performance. The Fund's longer duration was constructed primarily with longer maturity TIPS. We believe longer maturity TIPS are attractive because of favorable breakeven levels relative to our inflation outlook and market technicals as a result of increasing demand from pension funds. We also have limited exposure to intermediate TIPS which may increase as the Federal Reserve gets closer to the end of its tightening cycle, which would result in a steepening of the yield curve. We continue to invest the majority of the Fund's assets in US Treasury Inflation Protected Securities (TIPS), while maintaining small positions in high yield corporate securities and investment grade credits. Our strategy was designed to benefit from both a potential decline in interest rates and rebound in lower rated, high yield corporate bonds after the sector experienced a lackluster fourth calendar quarter in 2005. As corporate valuations improved during the first quarter of 2006, we have maintained a slightly higher concentration of TIPS relative to our minimum allowable amount (80%). Corporate securities, particularly those in the high yield sector, had the most positive impact on Fund performance during the period. Fixed income investors showed a strong appetite for yield and, as we anticipated, the high yield sector responded positively to this trend during the first calendar quarter of 2006. Late in the period we purchased small currency positions in Japan, Sweden and Norway. Fundamentally, we believe the US dollar is a weak currency, and when interest rates stop increasing, we think the dollar may face significant pressures. We believe the 7 currencies of Japan, Sweden and Norway are positioned to perform better than the US dollar. OUTLOOK Given that the Fund's Benchmark is composed entirely of US TIPS, the Fund's current allocation of 87% TIPS is underweighted. We expect to shift to a more bulleted maturity structure and increase duration when we believe the Federal Reserve Board is closer to concluding its tightening cycle. In addition, as credit opportunities become more attractive, we plan to reduce the Fund's exposure to TIPS further, probably to our minimum position of 80%, while increasing our allocation to corporate securities.

cannot guarantee future results. Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. For illustrative purposes, the chart above reflects the growth of a hypothetical investment of $100,000 in the Fund, since its inception. For illustrative purposes, the chart above also reflects the growth of a hypothetical investment in the former primary benchmark of the Fund, the Lehman US Government Bond Index (the "Former Benchmark"), compared to the performance of the Fund from the Fund's inception date and 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 from the Former Benchmark to the Lehman US 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. For illustrative purposes, 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, 2006. The chart above also compares the performance of the Fund to the Lipper Treasury Inflation Protected Securities Fund Index from December 31, 2004 and through March 31, 2006. The performance of the New Benchmark and of the Lipper Treasury Inflation Protected Securities Fund Index was linked to the performance of the Former Benchmark as of December 31, 2004. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers, performance would be lower. (a) Since index performance data is not available coincident with the Fund's inception date, comparative performance is presented from the month end closest to the Fund's inception date. (b) See page 15 for a description of the indexes. (c) The mountain chart is based on the Fund's minimum initial investment of $100,000. WHAT YOU SHOULD KNOW Securities issued by US government agencies are not issued, and may not be guaranteed by the US government. Effective December 15, 2004, the Fund's name and investment strategy changed. The Fund is now named the Loomis Sayles Inflation Protected Securities Fund, and its strategy emphasizes inflation-protected debt securities issued by the US Treasury (TIPS). The principal value of the types of securities are periodically adjusted according to the rate of inflation and repayment of the original bonds is guaranteed by the US government. 8 FUND AND MANAGER REVIEW LOOMIS SAYLES INSTITUTIONAL HIGH INCOME FUND [PHOTO] Daniel Fuss Manager since January 1996 FUND FACTS SYMBOL | LSHIX OBJECTIVE | High total investment return through a combination of current income and capital appreciation STRATEGY | Invests in primarily lower-rated fixed-income securities and other securities that are expected to produce a relatively high level of income (including income-producing preferred and common stocks) FUND INCEPTION DATE | 6/5/96 FUND REGISTRATION DATE | 3/7/97 EXPENSE RATIO | 0.75% TOTAL NET ASSETS | $127.2 million PORTFOLIO REVIEW Favorable security selections in the high yield, emerging market and convertibles sectors helped the Fund significantly outperform its Benchmark, the Lehman High Yield Index, for the six months ended March 31, 2006. Our primary strategies during the period included taking advantage of select non-benchmark opportunities among non-dollar, convertible, emerging market, preferred/equity and investment grade credit securities. With the global economy improving, we focused on sovereign opportunities, particularly in Latin America and Southeast Asia. In addition, we shortened the Fund's duration during the period in anticipation of higher interest rates. In terms of sectors, the convertibles, preferred/equity and emerging markets areas made the greatest positive contributions to Fund performance. Convertibles outperformed due to improving corporate capital structures in select names. Continental Airlines convertibles were the Fund's top-performing individual securities, due to strength in the underlying stock. The preferred/equity sector's positive influence on performance was driven by specific names that performed well. In the emerging markets sector, the combination of strong global economic growth, rising commodity prices and improving credit quality led to strong performance. For example, Republic of Argentina warrants, which are positively correlated with Argentina's Gross Domestic Product, were top performers on strong signs of an economic recovery in the country. On the downside, the Canadian sector was a slight drag on relative performance, primarily due to currency depreciation. Among industries represented in the Fund, communications performed well due to capital restructuring improvements and fiber/bandwidth demand. Level 3 Communications convertibles were top performers for the Fund, due to strong profitability forecasts for the company stemming from growing demand for telecom products. In addition, strong demand within the biotech and pharmaceutical markets led to positive performance for consumer non-cyclicals. The individual technology stocks we selected also outperformed. Bankruptcies led to declines in the auto and electric industries. In particular, Delphi and Calpine bonds detracted from the Fund's performance. We maintained a position in certain short Calpine paper and held all our Delphi bonds. Solo Cup also was a negative contributor to performance, due to a credit downgrade. We sold the position early in 2006. OUTLOOK Credit spreads remain tight, but opportunities are still present, particularly in the below-investment grade categories. The high yield sector appears fairly valued, as market and economic conditions are favorable. Nevertheless, from a shorter-term, tactical perspective, the market seems rich and vulnerable to spreads snapping back to the middle or higher end of the range. Therefore, although we anticipate attractive opportunities in selected 9 high yield securities, our overall assessment is one of caution. We continue to focus our efforts on careful credit research, seeking improving credit quality in select names. Defaults are expected to rise modestly in 2006, but there is no indication credit quality is deteriorating on a widespread basis. We will continue to look for opportunities in technical flare-ups.

Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers, performance would be lower. (a) Shares of the Fund were registered for offer and sale under the Securities Act of 1933 on March 7, 1997. In accordance with regulations, performance information is provided for the period beginning on March 7, 1997 ("Registration"). Performance from inception is also provided for the convenience of our long-term shareholders. Since index performance data is not available coincident with the Fund's inception and registration dates, comparative performance is presented from the month end closest to the Fund's inception and registration dates. (b) See page 15 for a description of the indexes. (c) The mountain chart is based on the Fund's minimum initial investment of $3,000,000. WHAT YOU SHOULD KNOW High yield securities are subject to a high degree of market and credit risk. The secondary market for these securities may lack liquidity which may adversely affect the value of the fund. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than those of the US. Securities issued by US government agencies are not issued, and may not be guaranteed by the US government. 10 FUND AND MANAGER REVIEW LOOMIS SAYLES INTERMEDIATE DURATION FIXED INCOME FUND [PHOTO] Cliff Rowe Manager since January 2003 Manager since December 2005 [PHOTO] Neil Burke Manager since December 2005 FUND FACTS SYMBOL | LSDIX OBJECTIVE | Above-average total return through a combination of current income and capital appreciation STRATEGY | Invests only in investment-grade fixed-income securities. The Fund's weighted average duration generally is two to five years FUND INCEPTION DATE | 1/28/98 EXPENSE RATIO | 0.40% TOTAL NET ASSETS | $41.3 million [PHOTO] Richard Raczkowski Manager since December 2005 PORTFOLIO REVIEW In a challenging climate for fixed income investors, the Fund slightly outperformed its Benchmark, the Lehman US Government/Credit Intermediate Index, for the six-month period ended March 31, 2006. The primary contributors to this outperformance included security selection and duration management. Throughout the period, we increased the Fund's duration by approximately half a year, but the Fund's interest-rate sensitivity still remained slightly short of the Benchmark's at the end of March, 2006. We do not plan to make any significant changes to the duration strategy in the near-term. The Fund maintained a slight yield advantage relative to the Benchmark during the fiscal period, while its overall quality remained comparable. Slight increases in securities with AA and A ratings contributed to this advantage, because they provided higher yields relative to comparable Treasuries with limited risk. In addition, we trimmed our holdings in US credits and increased exposure to US Treasuries and the asset-backed securities market. In general, these allocation changes have come at the expense of the BBB-rated sector, a quality bucket that has contributed healthy returns throughout the past six months, but which now appears to be rich as a whole, given the group's potential risks and tight spreads relative to lower-risk instruments. The Fund's out-of-Benchmark allocations to mortgage-backed securities (especially 15-year mortgages) and asset-backed securities with shorter maturities (particularly auto loans) contributed positively to performance during the six months. Fears of extension risk (as interest rates rise, the likelihood of prepayment decreases) provided an opportunity for us to purchase mortgage-backed securities at favorable prices. Within the corporate sector, investment-grade financials and industrials posted strong returns. Security selection was an important driver of return within these areas. In addition, the Fund's emphasis on consumer non-cyclicals and its equal-weight position in consumer cyclicals led to outperformance relative to the Benchmark's sectors. In terms of individual issues, a few short-term US Treasury notes made the greatest contributions to Fund performance during the period. The Fund's holdings in Residential Capital Corp. also performed well on expectations that the company would separate from GMAC. As interest rates rose, a few longer-duration US Treasury notes were the largest detractors to the Fund's performance, particularly in the first calendar quarter of 2006. The Fund's avoidance of the Agency sector proved somewhat costly, because Agencies performed well on a relative basis. In addition, basic industries detracted slightly from the Fund's relative performance during the six-month period, primarily for issue-specific reasons. OUTLOOK We believe the US economy may slow, but growth should remain at a healthy, close-to-trend pace into summer. Our forecast calls for vigorous real GDP growth for the first half of 2006, slowing to a more moderate pace in the second half of the year. The end of the housing boom could temper consumer enthusiasm for spending. But we believe higher net exports, greater business capital 11 investment, and stronger spending by state and local governments may offset slowing consumer-spending trends. Global economic growth also is looking favorable, in our view, with Europe and Japan finally seeing stronger economic momentum. With a federal funds rate of 4.75% as of March 31, 2006, we believe the Federal Reserve Board is at or close to a "neutral" zone, neither stimulating nor suppressing economic activity. Our forecast is for inflation to remain in check, reducing the risk that the Fed will need to raise rates much beyond 5%. Corporate investors are faced with tight spread levels, but the corporate market could outperform Treasuries by a small margin, given still-healthy profit growth in a supportive economic environment.

Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month-end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers, performance would be lower.

WHAT YOU SHOULD KNOW High yield securities are subject to a high degree of market and credit risk. The secondary market for these securities may lack liquidity, which may adversely affect the value of the fund. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than those of the US. Securities issued by US government agencies are not issued, and may not be guaranteed by the US government. 12 FUND AND MANAGER REVIEW LOOMIS SAYLES INVESTMENT GRADE FIXED INCOME FUND [PHOTO] Daniel Fuss Manager since July 1994 [PHOTO] Steven Kaseta Manager since November 2002 Manager since February 2002 FUND FACTS SYMBOL | 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 rated fixed-income securities and up to 10% of its assets in preferred stocks FUND INCEPTION DATE | 7/1/94 FUND REGISTRATION DATE | 3/7/97 EXPENSE RATIO | 0.55% TOTAL NET ASSETS | $179.3 million PORTFOLIO REVIEW Favorable sector and security selections accounted for the Fund's outperformance relative to its Benchmark, the Lehman US Government/Credit Index, for the six months ended March 31, 2006. In particular, our security selections within the emerging markets, high yield and international sectors--sectors that are not represented in the Benchmark--helped generate the majority of the Fund's performance advantage. In addition to these sectors, we invested a large portion of the Fund's portfolio in other non-Benchmark sectors, including convertibles, Canada, preferred equity and mortgage-related. Tighter yield spreads in the US bond market caused investors to seek higher yields. This sentiment helped drive performance in the high yield, emerging market and international sectors. In addition, improving fundamentals and increased global demand for commodities helped emerging market and international bonds. Convertible securities and short-duration Canadian Securities bonds also were positive. The US government agency sector performed poorly versus other sectors within the Fund and detracted from performance during the period. Yield-curve positioning was the primary culprit within this sector. From a country perspective, Mexico, the United Kingdom and the United States provided the greatest positive contributions to Fund performance. Improving fundamentals and good security selection accounted for positive results from the Fund's Mexican bonds. Security selection also was the driver for the Fund's UK bonds. The Fund's allocations to the US high yield and credit sectors and the large domestic weighting within the portfolio also contributed to positive performance. The largest detractor to Fund performance was the supranational category, where bonds denominated in New Zealand dollars struggled as that currency declined. The banking and transportation industries had the greatest positive impact on Fund performance for the period, due to favorable security selection. Examples include Citibank (denominated in Brazilian reals) and Atlas Air Inc. In addition, the US Treasury sector was among the top contributors, primarily due to the sector's relatively short duration and large weighting in the Fund. Issue-specific factors in the Fund's financial holdings, which included GE Capital Corp., detracted from relative performance. The Fund remains positioned in a "barbell" fashion in an attempt to limit interest rate risk. Overall, the Fund maintains a slightly defensive slant, with a shorter duration than the Benchmark. OUTLOOK We believe the downside risk for bond prices is lower now, because the market is closer to the peak in the federal funds rate and yields in general. Volatility may arise over the near term, as investors scour every bit of data in an effort to predict when the Federal Reserve Board will stop raising interest rates. We believe any spike in rates may be short lived as the market anticipates slower economic growth ahead. Also serving as a possible cap on rates is demand for US bonds, which we believe may remain strong, as the United States remains a "higher yield" country, despite rate gains in other parts of the 13 world. Investors in corporate bonds are faced with tight spreads that could widen slightly. Nevertheless, the corporate market could outperform Treasuries by a small margin, given still-healthy profit growth in a supportive economic environment. With respect to the high yield market, we continue to find attractive opportunities, but we remain somewhat cautious because we believe valuations are stretched currently. We view this as a good time to reduce certain high yield exposures and look for opportunities to move back into the market at a later date and when spreads may be wider.

Average annual total returns assume reinvestment of dividends and capital gains distributions. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance current to the most recent month end, please visit the Loomis Sayles website. Current performance may be higher or lower than quoted. Returns do not reflect the taxes that a shareholder would pay on fund distributions or the redemption of shares. Performance data reflects certain fee waivers and reimbursements. Without such waivers, performance would be lower. (a) Shares of the Fund were registered for offer and sale under the Securities Act of 1933 on March 7, 1997. In accordance with regulations, performance information is provided for the period beginning on March 7, 1997 ("Registration"). Performance from inception is also provided for the convenience of our long-term shareholders. Since index performance data is not available coincident with the Fund's inception and registration dates, comparative performance is presented from the month end closest to the Fund's inception and registration dates. (b) See page 15 for a description of the indexes. (c) The mountain chart is based on the Fund's minimum initial investment of $3,000,000. WHAT YOU SHOULD KNOW High yield securities are subject to a high degree of market and credit risk. The secondary market for these securities may lack liquidity which may adversely affect the value of the fund. Foreign investments involve special risks, including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets. Foreign countries may have different accounting standards than those of the US. Securities issued by US government agencies are not issued, and may not be guaranteed by the US government. 14 ADDITIONAL INFORMATION INDEX DEFINITIONS Indexes are unmanaged and do not have expenses that affect results, unlike mutual funds. Index returns are adjusted for the reinvestment of capital gain distributions and income dividends. It is not possible to invest directly in an index.

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 1-800-SEC-0330. UNDERSTANDING YOUR FUND'S EXPENSES As a mutual fund shareholder you incur two types of costs: (1) transaction costs, including redemption fees and certain exchange fees; and (2) ongoing costs, including management fees, distribution and/or service fees (12b-1 fees), and other Fund expenses. These costs are described in more detail in 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 shares shows the actual amount of Fund expenses you would have paid on a $1,000 investment in the Fund from October 1, 2005 through March 31, 2006. 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. 15 LOOMIS SAYLES BOND FUND Beginning Ending Expenses Paid Account Value Account Value During Period* Institutional Class 10/1/05 3/31/06 10/1/05 - 3/31/06 ------------------- ------------- ------------- ----------------- Actual $1,000.00 $1,032.90 $3.80 Hypothetical (5% return before expenses) $1,000.00 $1,021.19 $3.78 Retail Class - ------------ Actual $1,000.00 $1,031.90 $5.06 Hypothetical (5% return before expenses) $1,000.00 $1,019.95 $5.03 Admin Class - ----------- Actual $1,000.00 $1,030.60 $6.33 Hypothetical (5% return before expenses) $1,000.00 $1,018.70 $6.29 *Expenses are equal to the fund's annualized expense ratio of 0.75%, 1.00% and 1.25% for the Institutional, Retail and Admin Class, respectively, multiplied by the average account value over the period, multiplied by 182/365 ( to reflect the half-year period).

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 investment management 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 (individually, a "Fund" and collectively, the "Funds"). 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). Information presented in these financial statements pertains to the fixed income funds of the Trust, the financial statements for the equity funds are presented in a separate report. The following 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 Fixed Income Fund (the "Intermediate Duration Fixed Income Fund") Loomis Sayles Investment Grade Fixed Income Fund (the "Investment Grade Fixed Income Fund") Each Fund offers Institutional Class Shares. Bond Fund and Global 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 can not be directly attributed to a Fund are generally apportioned based on the relative net assets of each of the Funds in the Trust. Expenses of a Fund are borne pro rata by the holders of each Class of shares, except that each Class bears expenses unique to that Class (including the Rule 12b-1 service and distribution fees and transfer agent fees applicable to such Class). In addition, each Class votes as a Class only with respect to its own Rule 12b-1 Plan. Shares of each Class would receive their pro rata share of the net assets of a Fund, if the Fund were liquidated. The Trustees approve separate dividends from net investment income on each class of shares. 2. SIGNIFICANT ACCOUNTING POLICIES. The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements. The Funds' financial statements are prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of management estimates that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. SECURITY VALUATION. Debt securities for which market quotations are readily available (other than short-term obligations with a remaining maturity of less than sixty days) are generally valued at market price, as reported by pricing services recommended by the investment adviser's pricing committee and approved by the Board of Trustees. Such pricing services generally use the most recent bid prices in the principal market in which such securities are normally traded. 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. Equity securities for which market quotations are readily available are valued at market value, as reported by pricing services recommended by the investment adviser's pricing committee and approved by the Board of Trustees. Such pricing services generally use the security's last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ National Market are valued at the NASDAQ Official Closing Price ("NOCP"), or if lacking a NOCP, at the most recent bid quotation on the NASDAQ National Market. Short-term obligations with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available (including restricted securities, if any) are valued at fair value as determined in good faith by the Fund's investment adviser using consistently applied procedures under the general supervision of the Board of Trustees. Investments in other investment companies are valued at the net assets values each day. The Funds may hold securities traded in foreign markets. Foreign securities are valued at the market price in the foreign market. However, if events occurring after the close of the foreign market (but before the close of regular trading on the New York Stock Exchange) are believed to materially affect the value of those securities, such securities are fair valued pursuant to procedures approved by the Board of Trustees. When fair valuing equity securities, a Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Fund calculates its net asset value. B. SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME. Security transactions are accounted for on trade date. Dividend income is recorded on ex-dividend date, or in the case of certain foreign securities, as soon thereafter as the 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. Investment income is recorded net of foreign taxes withheld when applicable. In determining net gain or loss on 87 securities sold, the cost of securities has been determined on an identified cost basis. Investment income 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 net assets of the Fund. C. FOREIGN CURRENCY TRANSLATION. The books and records of the Funds are maintained in U.S. dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the period. Purchases and sales of investment securities, income and expenses are translated on the respective dates of such transactions. Since the values of investment securities are presented at the foreign exchange rates prevailing at the end of the period, it is not practical to isolate that portion of the results of operations arising from changes in exchange rates from fluctuations arising from changes in market prices of the 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, at the end of the fiscal period, resulting from changes in exchange rates. Certain Funds 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. Each Fund may purchase investments of foreign issuers. Investing in securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies and securities of the U.S. government. These risks include revaluation of currencies and the risk of appropriation. Moreover, the markets for securities of many foreign issuers may be less liquid and the prices of such securities may be more volatile than those of comparable U.S. companies and the U.S. government. D. FORWARD FOREIGN CURRENCY CONTRACTS. Each Fund that may invest in foreign investments may enter into forward foreign currency exchange contracts. Contracts to buy generally are used to acquire exposure to foreign currencies, while contracts to sell 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 Fund's Statement of Assets and Liabilities. The U.S. dollar value of the currencies the Fund has committed to buy or sell represents the aggregate exposure to each currency the Fund has acquired or hedged through currency contracts outstanding at period end. All contracts are "marked-to-market" daily at the applicable exchange rates and any 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. At March 31, 2006, the Global Bond Fund had the following open forward foreign currency exchange contracts: LOCAL AGGREGATE UNREALIZED DELIVERY CURRENCY FACE TOTAL APPRECIATION DATE AMOUNT AMOUNT VALUE (DEPRECIATION) - --------------------------------------------------------------------------------------- Australian Dollar (sell) 05/15/2006 40,475,000 $29,868,748 $28,945,248 $ 923,500 Australian Dollar (sell) 05/24/2006 4,020,000 2,955,424 2,874,482 80,942 Mexican Peso (buy) 04/26/2006 62,700,000 5,872,252 5,741,842 (130,410) Mexican Peso (sell) 04/26/2006 62,700,000 5,923,196 5,741,842 181,354 New Zealand Dollar (sell) 05/15/2006 8,135,000 5,485,267 4,987,669 497,598 E. 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 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. Accordingly, no provision for federal income tax has made. 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. 88 NOTES TO FINANCIAL STATEMENTS - CONTINUED MARCH 31, 2006 (UNAUDITED) F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on ex-dividend date. The timing and characterization of certain income and capital gains distributions are determined in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent differences are primarily due to differing treatments for book and tax purposes of items such as redemptions in-kind, foreign currency transactions, defaulted bond interest, premium amortization accruals, distributions from real estate investment trusts and reclassification of 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 deferred trustees' fees, premium amortization accruals, corporate action adjustments, mark-to-market on forward currency contracts and wash sales. Distributions from net investment income and short-term capital gains are considered to be ordinary income for tax purposes. Tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2005 was as follows: 2005 DISTRIBUTIONS PAID FROM: - - --------------------------------------- ORDINARY LONG-TERM INCOME CAPITAL GAINS TOTAL - - ------------ ------------- ------------ Bond Fund $216,485,259 $ -- $216,485,259 Fixed Income Fund 34,745,920 -- 34,745,920 Global Bond Fund 25,353,794 2,052,098 27,405,892 Inflation Protected Securities Fund 434,112 -- 434,112 Institutional High Income Fund 8,125,448 -- 8,125,448 Intermediate Duration Fixed Income Fund 1,688,139 64,438 1,752,577 Investment Grade Fixed Income Fund 11,463,633 3,486,246 14,949,879 As of September 30, 2005, capital loss carryforwards and post-October losses were as follows: FIXED INCOME GLOBAL INFLATION PROTECTED BOND FUND FUND BOND FUND SECURITIES FUND - - ------------ ------------ --------- ------------------- Capital loss carryforward: Expires September 30, 2010 $ -- $ -- $ -- $ -- Expires September 30, 2011 (73,376,816) (9,158,202) -- -- Expires September 30, 2012 -- -- -- -- Expires September 30, 2013 -- -- -- -- ------------ ------------ --------- ------------------- Total capital loss carryforward (73,376,816) (9,158,202) -- -- ------------ ------------ --------- ------------------- Deferred net capital losses (post October 2004) -- -- -- (10,158) ------------ ------------ --------- ------------------- INSTITUTIONAL HIGH INTERMEDIATE DURATION INVESTMENT GRADE INCOME FUND FIXED INCOME FUND FIXED INCOME FUND - - ------------------ --------------------- ----------------- Capital loss carryforward: Expires September 30, 2010 $(1,230,714) $ -- $ -- Expires September 30, 2011 (6,736,705) -- -- Expires September 30, 2012 -- -- -- Expires September 30, 2013 -- (3,797) -- ------------------ --------------------- ----------------- Total capital loss carryforward (7,967,419) (3,797) -- ------------------ --------------------- ----------------- Deferred net capital losses (post October 2004) -- (121,443) -- ------------------ --------------------- ----------------- G. REPURCHASE AGREEMENTS. Each Fund, through its custodian, receives delivery of the underlying securities collateralizing repurchase agreements. It is each Fund's policy that the market value of the collateral be at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party arrangements whereby the collateral is held at the custodian bank in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty including possible delays or restrictions upon a Fund's ability to dispose of the underlying securities. H. DELAYED DELIVERY COMMITMENTS. Each Fund may purchase or sell securities on a when issued or forward commitment basis. Payment and delivery may take place a month or more after the date of the transaction. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract. Collateral consisting of liquid securities or cash and cash equivalents is maintained in an amount at least equal to these commitments with the custodian. 89 I. SECURITIES LENDING. The Funds have entered into an agreement with State Street Bank and Trust Company ("State Street Bank"), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value of the loaned international or domestic securities, respectively, when the loan is initiated. Thereafter, the value of the collateral must remain at not less than 102% of the market value of the loaned securities for U.S. equities and U.S. corporate debt; not less than 105% of the market value of the loaned securities for non-U.S. equities and not less than 100% of the market value of the loaned securities for the U.S. government and agency securities, sovereign debt issuers 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. The market value of securities on loan to borrowers and the value of collateral held by the Funds with respect to such loans at March 31, 2006, were as follows: FUND MARKET VALUE COLLATERAL ---- ------------ ------------ Bond Fund $961,906,386 $981,993,796 Fixed Income Fund 95,194,372 97,146,936 Global Bond Fund 25,560,370 26,113,019 Inflation Protected Securities Fund 2,354,545 2,403,546 Institutional High Income Fund 13,197,327 13,526,688 Intermediate Duration Fixed Income Fund 1,822,391 1,863,856 Investment Grade Fixed Income Fund 19,006,197 19,390,817 J. INDEMNIFICATIONS. Under the Funds' organizational documents, their officers and Trustees are indemnified against certain liability 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 Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote. 3. PURCHASES AND SALES OF SECURITIES. For the six months ended March 31, 2006, purchases and sales of securities (excluding short-term investments) were as follows: U.S. GOVERNMENT/AGENCIES OTHER SECURITIES ------------------------- --------------------------- FUND PURCHASES SALES PURCHASES SALES - ---- ------------ ------------ -------------- ------------ Bond Fund $111,073,520 $246,195,676 $1,459,254,826 $ 90,384,117 Fixed Income Fund -- 158,645 79,055,143 38,895,195 Global Bond Fund 82,829,284 132,269,321 302,449,745 427,009,927 Inflation Protected Securities Fund 2,197,829 2,069,954 549,924 366,315 Institutional High Income Fund 1,294,314 -- 25,829,184 13,939,792 Intermediate Duration Fixed Income Fund 8,100,809 5,882,226 3,694,338 3,906,988 Investment Grade Fixed Income Fund 6,235,596 42,398,509 36,520,844 7,452,708 4.

Each committee member receives $4,000 or $5,000 for each contract and governance or audit committee meeting, respectively, that he or she attends in person and $2,000 or $2,500 for each contract and governance or audit committee 92 NOTES TO FINANCIAL STATEMENTS - CONTINUED MARCH 31, 2006 (UNAUDITED) meeting, respectively, that he or she attends telephonically. These fees are allocated among the funds in the Trusts based on a formula that takes into account, among other factors, the relative net assets of each fund. Trustees are reimbursed for travel expenses in connection with attendance at meetings. Prior to November 18, 2005, the Trusts had co-chairmen of the Board. Prior to October 1, 2005, each independent Trustee received, in the aggregate, a retainer fee at the annual rate of $50,000 and meeting attendance fees of $5,000 for each meeting of the Board of Trustees that he or she attended. The co-chairmen of the Board each received an additional annual retainer of $25,000. Each committee chairman received an additional retainer fee at the annual rate of $7,000. Each committee member received $3,750 for each committee meeting that he or she attended. In addition, during the period October 1, 2005 to November 18, 2005, each co-chairman received an additional one-time payment of $25,000 as compensation for their services as chairman. Prior to January 1, 2006, each committee member was compensated $4,000 for each Audit Committee meeting that he or she attended in person and $2,000 for such meeting he or she attends telephonically. A deferred compensation plan (the "Plan") is available to the Trustees on a voluntary basis. Each participating Trustee will receive an amount equal to the value that such deferred compensation would have been had it been invested in a designated fund or certain other funds of the Trusts on the normal payment date. Deferred amounts remain in the fund until distributed in accordance with the Plan. Additionally, the Board of Trustees has approved the use of the Funds' assets to pay their portion of the annual salary for 2005 of an employee at IXIS Advisors who supports the Funds' Chief Compliance Officer. For the period from October 1st through December 31, 2005, each Fund's portion of such expense was approximately $575. E. REDEMPTION FEES. Shareholders of the Bond Fund and Global Bond Fund will be charged a 2% redemption fee if they redeem, including redeeming by exchange, any class of shares of these Funds within 60 days of their acquisition (including acquisition by exchange). The redemption fee is intended to offset the costs to the Funds of short-term trading, such as portfolio transaction and market impact costs associated with redemption activity and administrative costs associated with processing redemptions. The redemption fee is deducted from the shareholder's redemption or exchange proceeds and is paid to the Fund. The "first-in, first-out" (FIFO) method is used to determine the holding period of redeemed or exchanged shares, which means that if shares were acquired on different days, the shares acquired first will be redeemed or exchanged first for purposes of determining whether the redemption fee applies. A new holding period begins with each purchase or exchange. These fees are accounted for as an addition to paid-in capital and are presented on the Statements of Changes in Net Assets. 5. LINE OF CREDIT. Bond Fund, Global Bond Fund and Inflation Protected Securities Fund, together with certain other Funds of the Loomis Sayles Funds Trusts and IXIS Advisor Funds Trusts, participate in a $75 million committed line of credit provided by State Street Bank. Advances under the line are taken primarily for emergency purposes. Interest is charged to a Fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a Fund is charged its pro rata portion of a facility fee equal to 0.09% per annum on the unused portion of the line of credit. For the six months ended March 31, 2006, the Funds had no borrowings under the agreement. 6. SHAREHOLDERS. At March 31, 2006, the Loomis Sayles Funded Pension Plan and Trust ("Pension Plan") and the Loomis Sayles Employees' Profit Sharing Retirement Plan held shares of beneficial interest in the Funds as follows: PROFIT SHARING FUND PENSION PLAN RETIREMENT PLAN - ---- ------------ --------------- Bond Fund $1,013,158 $1,279,452 Global Bond Fund 682,121 368,937 Inflation Protected Securities Fund -- 235,998 Institutional High Income Fund 308,633 641,092 Intermediate Duration Fixed Income Fund -- 59,165 At March 31, 2006, Loomis Sayles owned 117,533 shares, equating to 12.98% of Inflation Protected Securities Fund shares outstanding.

PORTFOLIO REVIEW The Fund underperformed its Benchmark, the Lehman High Yield Index, for the six months ended March 31, 2006, primarily because the securities in the Fund's portfolio were higher average quality relative to the Benchmark. Because we strive to maintain an overall credit quality of "BB," the Fund tends to invest in more securities at the higher quality end of the high yield sector than the Benchmark. In addition, we also may invest in investment grade credit. In general, lower-quality securities outperformed during the period as investors searched for yield in a low-return environment. Investment grade corporate spreads changed little during the period, and demand for the sector has been softening despite healthy corporate profits and an upbeat economy. On the positive side, the Fund's out-of-Benchmark allocations to emerging market debt and convertible bonds made the greatest contributions to relative performance during the period. Emerging market debt continued to see strong inflows, reflecting the sector's improving credit quality characteristics and attractive yields. Brisk demand for emerging market securities caused spreads to tighten to near-record levels. Strong issue selection within the technology and wire-line industries boosted performance within the convertibles sector. Strong issue selection within the media/cable industry boosted performance, while holdings in sovereign bonds benefited from strong demand for emerging market securities. From an individual-security perspective, the Fund's position in US-dollar-denominated Federal Republic of Brazil bonds had the most positive impact on relative performance. The Fund's allocation to the auto industry detracted from relative performance during the period due to bankruptcies and other negative news. Among individual holdings, the Fund's position in Calpine, a utility company that filed for bankruptcy during the period, had the most negative impact on performance and it was sold. OUTLOOK The current environment of solid profit growth, low defaults and favorable lending terms provides a favorable backdrop for the credit sectors. After a strong first quarter, US economic growth may slow in the second quarter, but we anticipate a healthy growth rate for the balance of 2006. From a strategic perspective, the high yield sector appears fairly valued, as economic conditions remain favorable and spreads stay within our expected range. However, from a shorter-term, tactical point of view, the market looks rich and vulnerable to spreads snapping back to the middle or wider end of the range. Therefore, although we see select, attractive opportunities within the high yield market, our overall assessment is one of caution. We believe investors may benefit from "playing the range," lightening up on high yield while spreads are tight and 1 moving back in if spreads widen. Down the road, if the economy starts to slow dramatically or the default rate begins to rise, we would consider significantly reducing exposure to high yield.

The Fund's portfolio managers collaborate with a team of in-house analysts to identify attractive total return investments in the securitized asset sector. Our bottom-up security selection process is the primary driver of the portfolio's structure and performance. This process may result in allocations to non-Benchmark sectors, including US Treasury and KEY FUND FACTS SYMBOL | LSSAX OBJECTIVE | High current income consistent with capital preservation. STRATEGY | Invest 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.

We build a Fund consistent with the analysts' ideas, Benchmark characteristics and prospectus guidelines. The resulting portfolio is designed to seek superior long-term performance relative to the securitized asset indexes and AAA-quality benchmarks. The following commentary covers the period from March 2, 2006, the Fund's inception date, through March 31, 2006. PORTFOLIO REVIEW In the current flat yield curve environment, short maturity securities have only a slight yield disadvantage, and their price movement is much less sensitive to interest rate moves. Accordingly, shorter maturity securities generally outperformed longer maturity securities. Despite their yield advantages, securitized bonds generally underperformed US Treasury securities with similar maturities, as higher interest rates fueled concerns of declining principal prepayments and extending durations. When interest rates are high, mortgage borrowers tend to prepay at a slower rate. For investors in mortgage-backed securities, this reduces the amount of principal available to reinvest at the new, higher interest rates. Within the securitized sectors, bonds with the least prepayment risk offered the best performance, as interest rates rose and duration extension concerns grew. In particular, commercial mortgage-backed securities (CMBS) outperformed. Typically, CMBS are protected from prepayment variability through prepayment penalties and other measures that serve to mitigate a borrower's ability to retire principal early. Asset-backed securities (ABS) may have similar protections, but the loans that back these bonds tend to have relatively small balances compared to mortgage loans, so they are less likely to be refinanced in response to interest rate moves. Mortgage-backed securities (MBS) were relative underperformers during the period. As interest rates rose to levels not seen in several years, investors worried that principal prepayment might slow significantly. Expectations of slower prepayments generally result in longer duration estimates for MBS, and longer durations lead to declining prices when interest rates rise. OUTLOOK We believe the yield curve may remain relatively flat in the intermediate term, potentially accompanied by a modest decline in rates. The relatively flat yield curve offers little incentive for investors seeking higher income to extend duration. Nevertheless, in a stable interest rate environment we anticipate that our MBS holdings should perform well because of their income advantages and potential price appreciation. We will continue to evaluate the effect of higher interest rates on the housing and MBS markets. 3 ADDITIONAL INFORMATION INDEX DEFINITIONS Lipper High Current Yield Funds Index is an equally weighted, unmanaged index of typically the 30 largest mutual funds within the high current yield funds investment objective. Source: Lipper, Inc. Lehman High Yield Index is a market-weighted, unmanaged index of fixed-rate, non-investment grade debt. Returns are adjusted for the reinvestment of capital gains distributions and income dividends. Indexes are unmanaged and do not have expenses that affect results, unlike most mutual funds. It is not possible to invest directly in an index.

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. Loomis Sayles High Income Opportunities Fund's Form N-Q is 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. Loomis Sayles Securitized Asset Fund commenced operation on March 2, 2006 and has not yet filed a Form N-Q. UNDERSTANDING YOUR FUND'S EXPENSES Typically, mutual fund shareholders incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases, redemption fees and certain exchange fees; 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. and IXIS Asset Management Advisors, L.P. ("IXIS 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 IXIS Advisors. The institutional investment advisory clients of Loomis Sayles and IXIS Advisors pay Loomis Sayles or IXIS 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 IXIS 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 IXIS 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 below shows the actual amount of Fund expenses ($0) you would have paid on a $1,000 investment in the Fund from October 1, 2005 (or commencement of operations, if later) through March 31, 2006. 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.

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 investment management 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 (each such series is a "Fund"). The following 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 IXIS Asset Management Advisors, L.P. ("IXIS Advisors"), and/or Loomis Sayles & Company, L.P. ("Loomis Sayles") and to institutional advisory clients of IXIS Advisors or Loomis Sayles that, in each case, meet the Funds' policies as established by Loomis Sayles. The financial statements of the other Funds of the Trust are presented in separate reports. 2. SIGNIFICANT ACCOUNTING POLICIES. The following is a summary of significant accounting policies consistently followed by each Fund in preparation of its financial statements. Each Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. SECURITY VALUATION. Debt securities for which market quotations are readily available (other than short-term obligations with a remaining maturity of less than sixty days) are generally valued at market price, as reported by pricing services recommended by the investment adviser's pricing committee and approved by the Board of Trustees. Such pricing services generally use the most recent bid prices in the principal market in which such securities are normally traded. 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. Equity securities, including closed-end investment companies, for which market quotations are readily available are valued at market value, as reported by pricing services recommended by the investment adviser's pricing committee and approved by the Board of Trustees. Such pricing services generally use the security's last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price. Securities traded on the NASDAQ National Market are valued at the NASDAQ Official Closing Price ("NOCP"), or if lacking a NOCP, at the most recent bid quotation on the NASDAQ National Market. Short-term obligations with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available (including restricted securities, if any) are valued at fair value as determined in good faith by each Fund's investment adviser using consistently applied procedures pursuant to the procedures approved by 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 its securities, a Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the foreign market and before the Fund calculates its net asset value. B. SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME. Security transactions are accounted for on trade date. Dividend income is recorded on ex-dividend date, or in the case of certain foreign securities, as soon thereafter as the 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. 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. C. FOREIGN CURRENCY TRANSLATION. The books and records of the Funds are maintained in U.S. dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the period. Purchases and sales of investment securities, income and expenses are translated on the respective dates of such transactions. Since the values of investment securities are presented at the foreign exchange rates prevailing at the end of the period, it is not practical to isolate that portion of the results of operations arising from changes in exchange rates from fluctuations arising from changes in market prices of the investment securities. Such changes are included with the net realized and unrealized gain or loss on investments. 21 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, 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. At March 31, 2006, there were no open foreign currency exchange contracts. The High Income Opportunities Fund may purchase investments of foreign issuers. Investing in securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies and securities of the U.S. government. These risks include revaluation of currencies and the risk of appropriation. Moreover, the markets for securities of many foreign issuers may be less liquid and the prices of such securities may be more volatile than those of comparable U.S. companies and the U.S. government. D. FORWARD FOREIGN CURRENCY CONTRACTS. The High Income Opportunities Fund may use forward foreign currency contracts. Contracts to buy are generally used to acquire exposure to foreign currencies, while contracts to sell are used to hedge the Fund's investments against currency fluctuation. Also, a contract to buy or sell can offset a previous contract. These contracts involve market risk in excess of the unrealized gain or loss reflected in the Fund's Statement of Assets and Liabilities. The U.S. dollar value of the currencies the Fund has committed to buy or sell represents the aggregate exposure to each currency the Fund has acquired or hedged through currency contracts outstanding at period end. All contracts are "marked-to-market" daily at the applicable exchange rates and any 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. At March 31, 2006, there were no open forward currency contracts. E. 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 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. Accordingly, no provisions for federal income tax has been made. 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. F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are recorded on ex-dividend date. The timing and characterization of certain income and capital gains distributions are determined in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent differences are primarily due to differing treatments for book and tax purposes of items such as premium amortization. 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 wash sales, deferred trustees fees, defaulted bond accruals and premium amortization accruals. Distributions from net investment income and short-term capital gains are considered to be 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 years ended September 30, 2005 was as follows: 2005 DISTRIBUTIONS PAID FROM: - - ------------------------------- ORDINARY LONG-TERM INCOME CAPITAL GAINS TOTAL - - -------- ------------- -------- High Income Opportunities Fund $722,198 $-- $722,198 Securitized Asset Fund -- -- -- 22 NOTES TO FINANCIAL STATEMENTS - CONTINUED FOR THE SIX MONTHS ENDED MARCH 31, 2006 (UNAUDITED) G. REPURCHASE AGREEMENTS. Each Fund, through its custodian, receives delivery of the underlying securities collateralizing repurchase agreements. It is each Fund's policy that the market value of the collateral be at least equal to 102% of the repurchase price, including interest. The repurchase agreements are tri-party agreements whereby the collateral is held at the custodian bank in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty including possible delays or restrictions upon a Fund's ability to dispose of the underlying securities. H. DELAYED DELIVERY COMMITMENTS. Each Fund may purchase or sell securities on a when issued or forward commitment basis. Payment and delivery may take place a month or more after the date of the transaction. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract. Collateral consisting of liquid securities or cash and cash equivalents is maintained in an amount at least equal to these commitments with the custodian. I. SECURITIES LENDING. The Funds have entered into an agreement with State Street Bank and Trust Company ("State Street Bank"), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value 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 of loaned securities for U.S. equities and U.S. corporate debt; at least 105% of the market value of loaned securities for non-U.S. equities; and at least 100% of the market value 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. The market value of securities on loan to borrowers and the value of collateral held by the Funds with respect to such loans at March 31, 2006, were as follows: MARKET VALUE VALUE OF FUND ON LOAN COLLATERAL - ---- ------------ ---------- High Income Opportunities Fund $4,044,214 $4,119,905 Securitized Asset Fund -- -- J. INDEMNIFICATIONS. Under the Funds' organizational documents, its officers and Trustees are indemnified against certain liability 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. PURCHASES AND SALES OF SECURITIES. For the six months ended March 31, 2006, purchases and sales of securities (excluding short-term investments and U.S. Government/Agency Securities) were as follows: U.S. GOVERNMENT/AGENCIES OTHER SECURITIES ------------------------ ---------------------- FUND PURCHASE SALES PURCHASE SALES - ---- ---------- ---------- ----------- ---------- High Income Opportunities Fund $4,057,480 $1,341,056 $14,571,052 $3,234,352 Securitized Asset Fund 9,011,621 410,534 1,481,358 -- 4.
