**Investment Objective** 

The Fund's investment objective is high total investment return through a combination of current income and capital appreciation.

**Market Conditions** 

The global bond market suffered pronounced weakness in 2022. Coming into the year, investors were already on edge as the investment community slowly began to understand that inflation would not be as "transitory" as initially expected. The outlook grew even more challenging after Russia's invasion of Ukraine caused a jump in commodity prices and additional disruptions in global supply chains. Consumer price inflation (CPI) further increased as a result, with year-over-year gains of more than 8% in each monthly report of the second quarter. Inflation stayed elevated for the rest of the year before showing signs of cooling in the fourth quarter. Still, CPI remained above 6% through the last three quarters of the year, well above the US Federal Reserve's (Fed's) 2% target.

These developments prompted the Fed and other major central banks to tighten monetary policy aggressively. The Fed, in addition to ending its stimulative quantitative easing policy, raised interest rates at seven consecutive meetings from March onward. The benchmark fed funds rate, which stood in a range of 0% to 0.25% at the start of 2022, finished the year at 4.25% to 4.50%. This represented the most aggressive increase in short-term rates since the early 1980s.

The backdrop of high inflation and rising rates weighed heavily on US Treasuries. The yield on the two-year note surged from 0.39% to 4.41% over the course of 2022, while the 10-year yield climbed from 1.44% to 3.88%. The Treasury market suffered its second consecutive year of negative returns in 2022 – the first time this has happened since 1958–59. One result of these moves was that the yield curve inverted significantly (meaning that short-term yields traded above those on longer-term debt), an unusual event that typically precedes a recession.

Investment grade corporate bonds posted a double-digit loss and lagged US Treasuries. In addition to suffering from the uptrend in prevailing yields, corporates experienced a large increase in yield spreads relative to government debt. Rising spreads were the result of investors' declining appetite for risk and concerns about the impact slowing economic growth could have on corporations' earnings and balance sheets.

High yield bonds, while finishing 2022 in the red, outperformed US Treasuries and other segments of the investment grade market. The category was helped by its higher income, lower interest rate sensitivity, and a relatively large representation of the energy sector. Senior loans, which experienced elevated demand due to their floating rate feature, were the best-performing segment of the fixed income market for the year with a return just below the break-even mark.

Securitized assets – including agency mortgage-backed securities (MBS), asset-backed securities (ABS), and commercial mortgage-backed securities (CMBS) – posted negative total returns but outperformed the broader US bond market due to the category's shorter duration (lower interest rate sensitivity). ABS, particularly credit card and auto ABS, were the strongest performers among securitized assets due to their higher quality, better liquidity, and shorter duration.

Emerging market bonds underperformed the US due to the combination of growth fears, investors' increased aversion to risk, the conflict in Ukraine, and negative headlines out of China. US-based investors were also hurt by a meaningful decline in emerging market currencies in relation to the US dollar.

**Performance Results** 

For the 12 months ended December 31, 2022, Institutional Class shares of the Loomis Sayles Bond Fund returned -12.49% at net asset value. The Fund outperformed its benchmark, the Bloomberg U.S. Government/Credit Bond Index, which returned -13.58%.

**Explanation of Fund Performance** 

Despite an extremely challenging year for fixed income markets, the Fund posted positive relative returns versus its benchmark. Yield curve positioning was the primary source of outperformance. The Fund has been targeting an overall duration shorter than that of the benchmark, which has been a positive contributor given the sharp upward movement in interest rates. We utilized Treasury futures to assist with meeting this objective. We have added back duration over the course of the year, but on a relative basis, remain short versus the benchmark. Securitized credit was also beneficial given the sector's shorter duration profile. Here, holdings in asset-backed securities (ABS) and collateralized loan obligations (CLOs) aided returns. An allocation to equities was also positive for relative returns. For equities, the team has employed a basket approach – seeking a diversified allocation that provides attractive dividend yields and capital appreciation potential versus fixed income. This exposure was reduced during the year as fixed income yields increased. Finally, performance was aided by defensive, reserve-like positions as risk-off sentiment prevailed.

------

Exposure to high yield credit was the primary source of underperformance for the Fund. High yield has lagged as aggressive central bank policy and an increasingly slower growth outlook have put pressure on risk assets. In addition, a handful of our higher conviction positions, particularly in the communications sector, have underperformed the broader market. The team's investment thesis for these higher conviction positions started to play out in the second half of the year, but was not enough to offset the drawdown experienced earlier in the period. An allocation to emerging market credit was also a detractor of relative returns, with holdings in Chinese property developers as the main sources of underperformance. Extended Covid-related lockdowns in China had exacerbated already-declining housing sales and government measures taken thus far to alleviate stresses on this sector had been limited, resulting in further bond price erosion. More recently, however, we have started to see coordinated efforts here as Chinese authorities release rounds of policies to support the property sector. Finally, convertible securities weighed on returns given the tumultuous equity market backdrop. Here, selected communications holdings were performance laggards.

**Outlook** 

Initial inflation data in the beginning of the fourth quarter of 2022 came in above expectations; however, subsequent readings were moderately positive, suggesting we may have passed peak inflation. The positive news appeared to usher in optimism that perhaps the Fed's aggressive rate hiking cycle is finally working to bring inflation down. As we moved closer to the potential peak in Fed policy, risk assets stabilized and spreads on investment grade and high yield corporates finished the quarter at tighter levels.

In our view, the credit cycle<sup>1</sup> is firmly in the late cycle stage and the risk of downturn has become more balanced. We expect growth to continue to trend lower as manufacturing and housing metrics have deteriorated; however, in our view the US consumer appears on solid footing, maintaining strong levels of excess savings and continuing to spend at a healthy rate. Labor markets remain tight. We've observed higher wages, cost of living adjustments, an elevated number of job openings and employers who are reluctant to shed workers in industries where they may have trouble getting them back, which could help to support consumer confidence. We believe a healthy consumer combined with positive corporate fundamentals and a strong banking system should help provide a floor to economic activity and support credit fundamentals to some degree.

While inflation has likely peaked and positive real rates should have the effect of slowing growth and rolling inflation down over time, we believe inflation will likely remain sticky and above the Fed's target throughout 2023, primarily as result of wage pressure. We now believe much of the movement from the Fed has occurred or is currently being priced into the market, which in turn may also put a cap on the Treasury curve. We're currently expecting an additional 50 bps of tightening in the first quarter of 2023, which would bring the policy rate up to 5.00% after the March meeting. In our view, the market continues to want to compress this cycle and lean towards a Fed pivot, but we believe inflation is structural at this point. We find it difficult for the Fed to begin cutting rates when inflation remains above their target. As a result, we're anticipating a Fed pause after the March meeting which would likely extend into the latter stage of 2023. Throughout the year, the Fed will likely be driven by the extent to which there is firm evidence of inflation moderating, and at this point, we have not eliminated the possibility that the next Fed move could be a rate hike. We expect the US 10-year bond yield to move only modestly higher from here and we continue to be positioned defensively on rate risk, but to a lesser extent than earlier in 2022.

We believe that value has returned to US fixed income markets. Bond structures (price, yield and spread) appear relatively attractive. While corporate bond spreads in both investment grade and high yield are currently tighter than their long-term averages, we believe overall yields remain favorable post the 2008 Great Financial Crisis (GFC). Dollar prices on bonds are also currently at post-GFC lows. We believe the combination of discount-to-par and attractive yield could be increasing the potential value opportunity in bonds. We remain mindful of the risks to the global economy, such as tighter financial conditions, slowing Chinese growth, the Eastern Europe conflict, disruptions to the global supply chain and the lingering effects of the Covid pandemic. All of the turmoil around the world leaves us with a wide range of potential outcomes for growth, inflation, and central bank policy response. With the likelihood of downturn in 2023 rising, we have been holding larger than average liquid reserves and seeking to maintain an up-in-quality bias. If volatility increases and we see what we view as more attractive yields and spreads, we would consider redeploying reserves. At the same time, short-term yields have risen meaningfully and we are comfortable with how we are being compensated as we wait for opportunities to potentially develop.

**UNDERSTANDING YOUR FUND'S EXPENSES** 

As a mutual fund shareholder you incur two types of costs: (1) *transaction costs*, and (2) *ongoing costs,* including management fees, distribution and/or service fees (12b-1 fees), and other fund expenses. Certain exemptions may apply. These costs are described in more detail in the Fund's prospectus. The following examples are intended to help you understand the ongoing costs of investing in the Fund and help you compare these with the ongoing costs of investing in other mutual funds.

The first line in the table for each class of Fund shares shows the *actual* amount of Fund expenses you would have paid on a $1,000 investment in the Fund from July 1, 2022 through December 31, 2022. 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 to other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

------

Please note that the expenses shown reflect ongoing costs only, and do not include any transaction costs. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative costs of owning different funds. If transaction costs were included, total costs would be higher.

**Notes to Financial Statements** 

**December** 31, 2022

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

Loomis Sayles Bond Fund (the "Bond Fund")

Loomis Sayles Investment Grade Fixed Income Fund (the "Investment Grade Fixed Income Fund")

Each Fund is a diversified investment company.

Each Fund offers Institutional Class shares. In addition, Bond Fund also offers Retail Class, Admin Class and Class N shares.

Each share class is sold without a sales charge. Retail Class and Admin Class shares pay a Rule 12b-1 fee. Admin Class shares are primarily intended for employer-sponsored retirement plans and are offered exclusively through intermediaries. Class N shares do not pay a front-end sales charge, a contingent deferred sales charge ("CDSC") or Rule 12b-1 fees. Class N shares are offered with an initial minimum investment of $1,000,000. Institutional Class shares are intended for institutional investors with a minimum initial investment of $100,000 for Bond Fund and $3,000,000 for Investment Grade Fixed Income Fund. Certain categories of investors are exempted from the minimum investment amounts for Class N and Institutional Class as outlined in the relevant Fund's prospectus.

Most expenses can be directly attributed to a Fund. Expenses which cannot be directly attributed to a Fund are generally apportioned based on the relative net assets of each of the Funds in Natixis Funds Trust I, Natixis Funds Trust II, Natixis Funds Trust IV, and Gateway Trust ("Natixis Funds Trusts"), and Loomis Sayles Funds I and Loomis Sayles Funds II ("Loomis Sayles Funds Trusts"), and Natixis ETF Trust and Natixis ETF Trust II ("Natixis ETF 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 (such as the Rule 12b-1 fees applicable to Retail Class and Admin Class) and transfer agent fees are borne collectively for Institutional Class, Retail Class, and Admin Class, and individually for Class N. In addition, each class votes as a class only with respect to its own Rule 12b-1 Plan. Shares of each class would receive their *pro rata* share of the net assets of a Fund if the Fund were liquidated. The Trustees approve separate distributions from net investment income on each class of shares.

2. **Significant Accounting Policies.** The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements. The Funds' financial statements follow the accounting and reporting guidelines provided for investment companies and are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. Management has evaluated the events and transactions subsequent to year-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds' financial statements.

**a. Valuation.** Registered investment companies are required to value portfolio investments using an unadjusted, readily available market quotation. Each Fund obtains readily available market quotations from independent pricing services. Fund investments for which readily available market quotations are not available are priced at fair value pursuant to the Funds' Valuation Procedures. The Board of Trustees has approved a valuation designee who is subject to the Board's oversight.

Unadjusted readily available market quotations that are utilized for exchange traded equity securities (including shares of closed-end investment companies and exchange-traded funds) include the last sale price quoted on the exchange where the security is traded most extensively. Futures contracts are valued at the closing settlement price on the exchange on which the valuation designee believes that, over time, they are traded most extensively. Shares of open-end investment companies are valued at net asset value per share.

Exchange traded equity securities for which there is no reported sale during the day are fair valued at the closing bid quotation as reported by an independent pricing service. Unlisted equity securities (except unlisted preferred equity securities) are fair valued at the last sale price quoted in the market where they are traded most extensively or, if there is no reported sale during the day, the closing bid quotation as reported by an independent pricing service. If there is no last sale price or closing bid quotation available, unlisted equity securities will be fair valued using evaluated bids furnished by an independent pricing service, if available.

Debt securities and unlisted preferred equity securities are fair valued based on evaluated bids furnished to the Fund by an independent pricing service or bid prices obtained from broker-dealers. Senior loans and collateralized loan obligations are fair valued at bid prices supplied by an independent pricing service, if available. Broker-dealer bid prices may be used to fair value debt, unlisted equities, senior loans and collateralized loan obligations where an independent pricing service is unable to price an investment or where an independent pricing service does not provide a reliable price for the investment. Forward foreign currency contracts are fair valued utilizing interpolated rates determined based on information provided by an independent pricing service.

The Funds may also fair value investments in other circumstances such as when extraordinary events occur after the close of a foreign market, but prior to the close of the New York Stock Exchange. This may include situations relating to a single issuer (such as a declaration of

**Notes to Financial Statements – continued** 

**December** 31, 2022

bankruptcy or a delisting of the issuer's security from the primary market on which it has traded) as well as events affecting the securities markets in general (such as market disruptions or closings and significant fluctuations in U.S. and/or foreign markets). When fair valuing a Fund's investments, the valuation designee may, among other things, use modeling tools or other processes that may take into account factors such as issuer specific information, or other related market activity and/or information that occurred after the close of the foreign market but before the time the Fund's net asset value ("NAV") is calculated. Fair valuation by the Fund(s) valuation designee may require subjective determinations about the value of the investment, and fair values used to determine a Fund's NAV may differ from quoted or published prices, or from prices that are used by others, for the same investments. In addition, the use of fair value pricing may not always result in adjustments to the prices of investments held by a Fund.

**b. Investment Transactions and Related Investment Income.** Investment transactions are accounted for on a trade date plus one day basis for daily NAV calculation. However, for financial reporting purposes, investment transactions are reported on trade date. Dividend income (including income reinvested) and foreign withholding tax, if applicable, are recorded on the ex-dividend date, or in the case of certain foreign securities, as soon as a Fund is notified, and interest income is recorded on an accrual basis. Loan consent fees, upfront origination fees and/or amendment fees are recorded when received and included in interest income on the Statements of Operations. Interest income is increased by the accretion of discount and decreased by the amortization of premium, if applicable. For securities with paydown provisions, principal payments received are treated as a proportionate reduction to the cost basis of the securities, and excess or shortfall amounts are recorded as income. Distributions received from investments in securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments or as a realized gain, respectively. In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. Investment income, non-class specific expenses and realized and unrealized gains and losses are allocated on a *pro rata* basis to each class based on the relative net assets of each class to the total net assets of the Fund.

**c. Foreign Currency Translation.** The books and records of the Funds are maintained in U.S. dollars. The values of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars, if any, 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 into U.S. dollars on the respective dates of such transactions.

Net realized foreign exchange gains or losses arise from sales of foreign currency, changes in exchange rates between the trade and settlement dates on securities transactions and the difference between the amounts of dividends, interest and foreign withholding taxes recorded in the Funds' books and records and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains or losses arise from changes in the value of assets and liabilities, other than investment securities, as of the end of the fiscal period, resulting from changes in exchange rates. Net realized foreign exchange gains or losses and the net change in unrealized foreign exchange gains or losses are disclosed in the Statements of Operations. For federal income tax purposes, net realized foreign exchange gains or losses are characterized as ordinary income, and may, if the Funds have net losses, reduce the amount of income available to be distributed by the Funds.

The values of investment securities are presented at the foreign exchange rates prevailing at the end of the period for financial reporting purposes. Net realized and unrealized gains or losses on investments reported in the Statements of Operations reflect gains or losses resulting from changes in exchange rates and fluctuations which arise due to changes in market prices of investment securities. For federal income tax purposes, a portion of the net realized gain or loss on investments arising from changes in exchange rates, which is reflected in the Statements of Operations, may be characterized as ordinary income and may, if the Funds have net losses, reduce the amount of income available to be distributed by the Funds.

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

**d. Forward Foreign Currency Contracts.** A Fund may enter into forward foreign currency contracts, including forward foreign cross currency contracts, to acquire exposure to foreign currencies or to hedge the Fund's investments against currency fluctuation. A contract can also be used to offset a previous contract. These contracts involve market risk in excess of the unrealized appreciation (depreciation) reflected in the Funds' Statements of Assets and Liabilities. The U.S. dollar value of the currencies a Fund has committed to buy or sell represents the aggregate exposure to each currency a Fund has acquired or hedged through currency contracts outstanding at period end. Gains or losses are recorded for financial statement purposes as unrealized until settlement date. Contracts are traded over-the-counter directly with a counterparty. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. Certain contracts may require the movement of cash and/or securities as collateral for the Fund's or counterparty's net obligations under the contracts. Forward foreign currency contracts outstanding at the end of the period, if any, are listed in each applicable Fund's Portfolio of Investments.

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

\| 48

**Notes to Financial Statements – continued** 

**December** 31, 2022

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

Futures contracts are exchange-traded. Exchange-traded futures contracts are standardized and are settled through a clearing house with fulfillment supported by the credit of the exchange. Therefore, counterparty credit risks to the Funds are reduced; however, in the event that a counterparty enters into bankruptcy, a Fund's claim against initial/variation margin on deposit with the counterparty may be subject to terms of a final settlement in bankruptcy court.

**f. When-Issued and Delayed Delivery Transactions.** A Fund may enter into when-issued or delayed delivery transactions. When-issued refers to transactions made conditionally because a security, although authorized, has not been issued. Delayed delivery refers to transactions for which delivery or payment will occur at a later date, beyond the normal settlement period. The price of when-issued and delayed delivery securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. The security and the obligation to pay for it are recorded by the Funds at the time the commitment is entered into. The value of the security may vary with market fluctuations during the time before the Funds take delivery of the security. No interest accrues to the Funds until the transaction settles.

Delayed delivery transactions include those designated as To Be Announced ("TBAs") in the Portfolios of Investments. For TBAs, the actual security that will be delivered to fulfill the transaction is not designated at the time of the trade. The security is "to be announced" 48 hours prior to the established trade settlement date. Certain transactions require the Funds or counterparty to post cash and/or securities as collateral for the net mark-to-market exposure to the other party. The Funds cover their net obligations under outstanding delayed delivery commitments by segregating or earmarking cash or securities.

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

There were no when-issued or delayed delivery securities held by the Funds as of December 31, 2022.

**g. Federal and Foreign Income Taxes.** The Trust treats each Fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund's tax positions for the open tax years as of December 31, 2022 and has concluded that no provisions for income tax are required. The Funds' federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next twelve months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. However, management's conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

A Fund may be subject to foreign withholding taxes on investment income and taxes on capital gains on investments that are accrued and paid based upon the Fund's understanding of the tax rules and regulations that exist in the countries in which the Fund invests. Foreign withholding taxes on dividend and interest income are reflected on the Statements of Operations as a reduction of investment income, net of amounts that have been or are expected to be reclaimed and paid. Dividends and interest receivable on the Statements of Assets and Liabilities are net of foreign withholding taxes. Foreign withholding taxes where reclaims have been or are expected to be filed and paid are reflected on the Statements of Assets and Liabilities as tax reclaims receivable. Capital gains taxes paid are included in net realized gain (loss) on investments in the Statements of Operations. Accrued but unpaid capital gains taxes are reflected as foreign taxes payable on the Statements of Assets and Liabilities, if applicable, and reduce unrealized gains on investments. In the event that realized gains on investments are subsequently offset by realized losses, taxes paid on realized gains may be returned to a Fund. Such amounts, if applicable, are reflected as foreign tax rebates receivable on the Statements of Assets and Liabilities and are recorded as a realized gain when received.

**h. Dividends and Distributions to Shareholders.** Dividends and distributions are recorded on the 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 defaulted and/or non-income producing securities, premium amortization, distribution re-designations, trust preferred securities, return of capital distributions received, capital gain distributions received, and paydown gains and losses. Permanent book and tax basis differences relating to shareholder distributions, net investment income and net realized gains will result in reclassifications to capital accounts reported on the Statements of Assets and Liabilities. Temporary differences between book and tax distributable earnings are primarily due to deferred Trustees' fees, wash sales, defaulted and/or non-income producing securities, return of capital distributions received, trust preferred securities, corporate actions, capital gain distributions received, premium amortization, foreign currency gains and losses and futures contract mark-to-market. Amounts of income and capital gain available to be distributed on a tax basis are determined annually, and at other times during the Funds' fiscal year as may be necessary to avoid knowingly declaring and paying a return of capital distribution. Distributions from net investment income and net realized short-term capital gains are reported as distributed from ordinary income for tax purposes.

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the years ended December 31, 2022 and 2021 was as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
|  | **2022 Distributions** | **2022 Distributions** | **2022 Distributions** | **2021 Distributions** | **2021 Distributions** | **2021 Distributions** |

Distributions paid to shareholders from net investment income and net realized capital gains, based on accounting principles generally accepted in the United States of America, are consolidated and reported on the Statements of Changes in Net Assets as Distributions to Shareholders. Distributions paid to shareholders from net investment income and net realized capital gains expressed in per-share amounts, based on accounting principles generally accepted in the United States of America, are separately stated and reported within the Financial Highlights.

As of December 31, 2022, the components of distributable earnings on a tax basis were as follows:

**i. Senior Loans.** A Fund's investment in senior loans may be to corporate, governmental or other borrowers. Senior loans, which include both secured and unsecured loans made by banks and other financial institutions to corporate customers, typically hold the most senior position in a borrower's capital structure, may be secured by the borrower's assets and have interest rates that reset frequently. Senior Loans can include term loans, revolving credit facility loans and second lien loans. A senior loan is often administered by a bank or other financial institution that acts as agent for all holders. The agent administers the terms of the senior loan, as specified in the loan agreement. Large loans may be shared or syndicated among several lenders. A Fund may enter into the primary syndicate for a loan or it may also purchase all or a portion of loans from other lenders (sometimes referred to as loan assignments), in either case becoming a direct lender. The settlement period for senior loans is uncertain as there is no standardized settlement schedule applicable to such investments. Senior loans outstanding at the end of the period, if any, are listed in each applicable Fund's Portfolio of Investments.

**j. Collateralized Loan Obligations.** A Fund may invest in collateralized loan obligations ("CLOs"). A CLO is a type of asset-backed security designed to redirect the cash flows from a pool of leveraged loans to investors based on their risk preferences. Cash flows from a CLO are split into two or more portions, called tranches, varying in risk and yield. The risk of an investment in a CLO depends largely on the type of the collateralized securities and the class of the instrument in which the Fund invests. CLOs outstanding at the end of the period, if any, are listed in each applicable Fund's Portfolio of Investments.

**k. Repurchase Agreements.** Each Fund may enter into repurchase agreements, under the terms of a Master Repurchase Agreement, under which each Fund acquires securities as collateral and agrees to resell the securities at an agreed upon time and at an agreed upon price. It is each Fund's policy that the market value of the collateral for repurchase agreements be at least equal to 102% of the repurchase price, including interest. Certain repurchase agreements are tri-party arrangements whereby the collateral is held in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon a Fund's ability to dispose of the underlying securities. As of December 31, 2022, each Fund, as applicable, had investments in repurchase agreements for which the value of the related collateral exceeded the value of the repurchase agreement. The gross value of repurchase agreements is included in the Statements of Assets and Liabilities for financial reporting purposes.

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

For the year ended December 31, 2022, neither Fund had loaned securities under this agreement.

**m. Indemnifications.** Under the Trust's organizational documents, its officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote.

**n. New Accounting Pronouncement.** In June 2022, the Financial Accounting Standards Board issued Accounting Standards Update 2022-03, "Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions" ("ASU 2022-03"). ASU 2022-03 clarifies the guidance in ASC 820 related to the measurement of fair value of an equity security subject to contractual sale restrictions, eliminating the ability to apply a discount to the fair value of such securities, and introducing related disclosure requirements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, and allows for early adoption. Management is currently evaluating the impact of applying this update.

In January 2021, the Financial Accounting Standards Board issued Accounting Standard Update 2021-01, Reference Rate Reform (Topic 848) ("ASU 2021-01"). ASU 2021-01 is an update of ASU 2020-04, which was issued in response to concerns about structural risks of interbank offered rates, and particularly the risk of cessation of the London Interbank Offered Rate ("LIBOR"), expected to occur no later than June 30, 2023. Regulators have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based and less susceptible to manipulation. ASU 2020-04 provides temporary guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 is elective and applies to all entities,

51 \|

**Notes to Financial Statements – continued** 

**December** 31, 2022

subject to meeting certain criteria, that have contracts that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 amendments offer optional expedients for contract modifications that would allow an entity to account for such modifications by prospectively adjusting the effective interest rate, instead of evaluating each contract, in accordance with existing accounting standards, as to whether reference rate modifications constitute the establishment of new contracts or the continuation of existing contracts. ASU 2021-01 clarifies that certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments are currently effective and an entity may elect to apply its provisions as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. In December 2022, the Financial Accounting Standards Board issued a further update to Topic 848 under ASU 2022-06, which defers the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the optional expedients provided in Topic 848. Management expects to apply the optional expedients when appropriate.

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;• Level 3—prices determined using significant unobservable inputs when quoted prices or observable inputs
are unavailable such as when there is little or no market activity for an asset or liability (unobservable inputs reflect each Fund's own assumptions in determining the fair value of assets or liabilities and would be based on the best
information available).

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

The Funds' pricing policies have been approved by the Board of Trustees. Investments for which market quotations are readily available are categorized in Level 1. Other investments for which an independent pricing service is utilized are categorized in Level 2. Broker-dealer bid prices for which the Funds have knowledge of the inputs used by the broker-dealer are categorized in Level 2. All other investments, including broker-dealer bid prices for which the Funds do not have knowledge of the inputs used by the broker-dealer, as well as investments fair valued by the valuation designee, are categorized in Level 3. All Level 2 and 3 securities are defined as being fair valued.

Under certain conditions and based upon specific facts and circumstances, the Fund's valuation designee may determine that a fair valuation should be made for portfolio investment(s). These valuation designee fair valuations will be based upon a significant amount of Level 3 inputs.

4. **Derivatives.** Derivative instruments are defined as financial instruments whose value and performance are based on the value and performance of an underlying asset, reference rate or index. Derivative instruments that the Funds used during the period include forward foreign currency contracts and futures contracts.

The Funds are subject to the risk that changes in foreign currency exchange rates will have an unfavorable effect on the value of Fund assets denominated in foreign currencies. The Funds may enter into forward foreign currency exchange contracts for hedging purposes to protect the value of the Funds' holdings of foreign securities. The Funds may also use forward foreign currency contracts to gain exposure to foreign currencies, regardless of whether securities denominated in such currencies are held in the Funds. During the year ended December 31, 2022, the Funds engaged in forward foreign currency contracts for hedging purposes.

The Funds are subject to the risk that changes in interest rates will affect the value of the Funds' investments in fixed-income securities. The Funds will be subject to increased interest rate risk to the extent that they invest in fixed-income securities with longer maturities or durations, as compared to investing in fixed-income securities with shorter maturities or durations. The Funds may use futures contracts to hedge against changes in interest rates and to manage duration without having to buy or sell portfolio securities. The Funds may also use futures contracts to gain investment exposure. During the year ended December 31, 2022, the Funds used futures contracts to manage duration.

The following is a summary of derivative instruments for Bond Fund as of December 31, 2022, as reflected within the Statements of Assets and Liabilities:

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

The volume of forward foreign currency contract and futures contract activity, as a percentage of net assets for the Funds, based on gross month-end or daily (as applicable) notional amounts outstanding during the period, including long and short positions at absolute value, was as follows for the year ended December 31, 2022:

---

| | | |
|:---|:---|:---|
| **Bond Fund** | **Forwards** | **Futures** |
|  Average Notional Amount Outstanding | 0.14% | 17.73% |
|  Highest Notional Amount Outstanding | 0.63% | 22.00% |
|  Lowest Notional Amount Outstanding | 0.00% | 9.76% |
|  Notional Amount Outstanding as of December 31, 2022 | 0.00% | 11.66% |

| | | |
|:---|:---|:---|
| **Investment Grade Fixed Income Fund** | **Forwards** | **Futures** |
|  Average Notional Amount Outstanding | 0.11% | 5.83% |
|  Highest Notional Amount Outstanding | 0.57% | 10.48% |
|  Lowest Notional Amount Outstanding | 0.00% | 1.14% |
|  Notional Amount Outstanding as of December 31, 2022 | 0.00% | 10.48% |

---

Notional amounts outstanding at the end of the prior period, if applicable, are included in the average notional amount outstanding.

Unrealized gain and/or loss on open futures is recorded in the Statements of Assets and Liabilities. The aggregate notional values of futures contracts are not recorded in the Statements of Assets and Liabilities, and therefore are not included in the Funds' net assets.

The actual collateral received or pledged, if any, may exceed the amounts shown in the table due to overcollateralization. Timing differences may exist between when contracts under the ISDA agreements are marked-to-market and when collateral moves. The ISDA agreements include tri-party control agreements under which collateral is held for the benefit of the secured party at a third party custodian, State Street Bank.

Counterparty risk is managed based on policies and procedures established by each Fund's adviser. Such policies and procedures may include, but are not limited to, minimum counterparty credit rating requirements, monitoring of counterparty credit default swap spreads and posting of collateral. A Fund's risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the Fund's aggregated unrealized gains and the amount of any collateral pledged to the counterparty, which may be offset by any collateral posted to the Fund by the

\| 56

**Notes to Financial Statements – continued** 

**December** 31, 2022

counterparty. ISDA master agreements can help to manage counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under these ISDA agreements, collateral is routinely transferred if the total net exposure in respect of certain transactions, net of existing collateral already in place, exceeds a specified amount (typically $250,000, depending on the counterparty). With exchange-traded derivatives, there is minimal counterparty credit risk to the Fund because the exchange's clearing house, as counterparty to these instruments, stands between the buyer and the seller of the contract. Credit risk still exists in exchange-traded derivatives with respect to initial and variation margin that is held in a broker's customer accounts. While brokers typically are required to segregate customer margin for exchange-traded derivatives from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its customers, U.S. bankruptcy laws will typically allocate that shortfall on a pro rata basis across all of the broker's customers, potentially resulting in losses to the Fund. Based on balances reflected on each Fund's Statement of Assets and Liabilities, the following table shows (i) the maximum amount of loss due to credit risk that, based on the gross fair value of the financial instrument, the Fund would incur if parties (including OTC derivative counterparties and brokers holding margin for exchange-traded derivatives) to the relevant financial instruments failed completely to perform according to the terms of the contracts and the collateral or other security, if any, for the amount due proved to be of no value to the Fund, and (ii) the amount of loss that the Fund would incur after taking into account master netting provisions pursuant to ISDA agreements, as of December 31, 2022:

These undertakings are in effect until April 30, 2023, may be terminated before then only with the consent of the Funds' Board of Trustees, and are reevaluated on an annual basis. Management fees payable, as reflected on the Statements of Assets and Liabilities, are net of waivers and/or expense reimbursements, if any, pursuant to these undertakings.

**b. Service and Distribution Fees.** Natixis Distribution, LLC ("Natixis Distribution"), which is a wholly-owned subsidiary of Natixis Investment Managers, LLC, has entered into a distribution agreement with the Trust. Pursuant to this agreement, Natixis Distribution serves as principal underwriter of the Funds of the Trust.

Pursuant to Rule 12b-1 under the 1940 Act, Bond Fund has adopted Distribution Plans relating to the Fund's Retail Class shares (the "Retail Class Plan") and Admin Class shares (the "Admin Class Plan").

Under the Retail Class Plan, Bond Fund pays Natixis Distribution 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 shares, as compensation for services provided by Natixis Distribution in connection with the marketing or sale of Retail Class shares or for payments made by Natixis Distribution to securities dealers or other financial intermediaries as commissions, asset-based sales charges or other compensation with respect to the sale of Retail Class shares, or for providing personal services to investors and/or the maintenance of shareholder accounts.

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

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

For the year ended December 31, 2022, the service and distribution fees for Bond Fund were as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | **Service Fees** | **Distribution Fees** | **Distribution Fees** |
| **Fund** | **Admin Class** | **Retail Class** | **Admin Class** |
|  Bond Fund | $78523 | $2534477 | $92064 |

---

For the year ended December 31, 2022, Natixis Distribution refunded Bond Fund $13,541 of prior year Admin Class service fees paid to Natixis Distribution in excess of amounts subsequently paid to securities dealers or financial intermediaries. Service and distribution fees on the Statements of Operations have been reduced by these amounts.

**c. Administrative Fees.** Natixis Advisors, LLC ("Natixis Advisors") provides certain administrative services for the Funds and contracts with State Street Bank to serve as sub-administrator. Natixis Advisors is a wholly-owned subsidiary of Natixis Investment Managers, LLC. Pursuant to an agreement among Natixis Funds Trusts, Loomis Sayles Funds Trusts, Natixis ETF Trusts and Natixis Advisors, each Fund pays Natixis Advisors monthly its *pro rata* portion of fees equal to an annual rate of 0.0540% of the first $15 billion of the average daily net assets of the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts, 0.0500% of the next $15 billion, 0.0400% of the next

$30 billion, 0.0275% of the next $30 billion and 0.0225% of such assets in excess of $90 billion, subject to an annual aggregate minimum fee for the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts of $10 million, which is reevaluated on an annual basis.

For the year ended December 31, 2022, the administrative fees for each Fund were as follows:

---

|:---|:---|
| **Fund** | **Administrative<br>Fees** |
|  Bond Fund | $2768894 |

**d. Sub-Transfer Agent Fees.** Natixis Distribution has entered into agreements, which include servicing agreements, with financial intermediaries that provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries that hold positions in the Funds and has agreed to compensate the intermediaries for providing those services. Intermediaries transact with the Funds primarily through the use of omnibus accounts on behalf of their customers who hold positions in the Funds. These services would have been provided by the Funds' transfer agent and other service providers if the shareholders' accounts were maintained directly at the Funds' transfer agent. Accordingly, the Funds have agreed to reimburse Natixis Distribution for all or a portion of the servicing fees paid to these intermediaries. The reimbursement amounts (sub-transfer agent fees) paid to Natixis Distribution are subject to a current per-account equivalent fee limit approved by the Funds' Board of Trustees, which is based on fees for similar services paid to the Funds' transfer agent and other service providers. Class N shares do not bear such expenses.

For the year ended December 31, 2022, the sub-transfer agent fees (which are reflected in transfer agent fees and expenses in the Statements of Operations) for Bond Fund were $4,007,644.

As of December 31, 2022, Bond Fund owes Natixis Distribution $43,889 in reimbursements for sub-transfer agent fees (which are reflected in the Statements of Assets and Liabilities as payable to distributor).

Sub-transfer agent fees attributable to Institutional Class, Retail Class and Admin Class are allocated on a *pro rata* basis to each class based on the relative net assets of each class to the total net assets of those classes.

**e. Trustees Fees and Expenses.** The Trust does not pay any compensation directly to its officers or Trustees who are directors, officers or employees of Natixis Advisors, Natixis Distribution, Natixis Investment Managers, LLC or their affiliates. The Chairperson of the Board of Trustees receives a retainer fee at the annual rate of $369,000. The Chairperson does not receive any meeting attendance fees for Board of Trustees meetings or committee meetings that he attends. Each Independent Trustee (other than the Chairperson) receives, in the aggregate, a retainer fee at the annual rate of $210,000. Each Independent Trustee also receives a meeting attendance fee of $10,000 for each meeting of the Board of Trustees that he or she attends in person and $5,000 for each meeting of the Board of Trustees that he or she attends telephonically. In addition, the chairperson of the Contract Review Committee, the chairperson of the Audit Committee and the chairperson of the Governance Committee each receive an additional retainer fee at the annual rate of $20,000. Each Contract Review Committee member is compensated $6,000 for each Committee meeting that he or she attends in person and $3,000 for each meeting that he or she attends telephonically. Each Audit Committee member is compensated $6,000 for each Committee meeting that he or she attends in person and $3,000 for each meeting that he or she attends telephonically. These fees are allocated among the funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF 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.

Effective January 1, 2023, each Governance Committee member is compensated $2,500 for each Committee meeting that he or she attends either in person or telephonically.

A deferred compensation plan (the "Plan") is available to the Trustees on a voluntary basis. The value of a participating Trustee's deferral account is based on theoretical investments of deferred amounts, on the normal payment dates, in certain funds of the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts as designated by the participating Trustees. Changes in the value of participants' deferral accounts are allocated *pro rata* among the funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts and are normally reflected as Trustees' fees and expenses in the Statements of Operations. Deferred amounts remain in the funds until distributed in accordance with the provisions of the Plan. The portions of the accrued obligations allocated to the Funds under the Plan are reflected as Deferred Trustees' fees in the Statements of Assets and Liabilities.

For the year ended December 31, 2022, net depreciation in the value of participants' deferral accounts are reflected on the Statements of Operations as a reduction to expenses, as follows:

---

| | |
|:---|:---|
| **Fund** | **Amount** |
|  Bond Fund | $(319076) |
|  Investment Grade Fixed Income Fund | (25110) |

**December** 31, 2022

Certain officers and employees of Natixis Advisors and Loomis Sayles are also officers and/or Trustees of the Trust.

**f. Affiliated Ownership.** As of December 31, 2022, Loomis Sayles Employees' Profit Sharing Retirement Plan held shares of Bond Fund representing 0.51% of the Fund's net assets.

Investment activities of affiliated shareholders could have material impacts on the Fund.

7. **Class-Specific Transfer Agent Fees and Expenses.** Transfer agent fees and expenses for Bond Fund attributable to Institutional Class, Retail Class and Admin Class are allocated on a *pro rata* basis to each class based on relative net assets of each class to the total net assets of those classes. Transfer agent fees and expenses attributable to Class N are allocated to Class N.

For year ended December 31, 2022, Bond Fund incurred the following class-specific transfer agent fees and expenses (including sub-transfer agent fees, where applicable):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Transfer Agent Fees and Expenses** | **Transfer Agent Fees and Expenses** | **Transfer Agent Fees and Expenses** | **Transfer Agent Fees and Expenses** |
| **Fund** | **Institutional<br>Class** | **Retail<br>Class** | **Admin<br>Class** | **Class N** |
|  Bond Fund | $3475089 | $762885 | $27710 | $4883 |

---

8. **Line of Credit.** Each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts, entered into a $500,000,000 committed unsecured line of credit provided by State Street Bank. Any one Fund may borrow up to $350,000,000 under the line of credit agreement (as long as all borrowings by all Funds in the aggregate do not exceed the $500,000,000 limit at any time), subject to each Fund's investment restrictions and its contractual obligations under the line of credit. Interest is charged to the Funds based upon the terms set forth in the agreement. In addition, a commitment fee of 0.15% per annum, payable at the end of each calendar quarter, is accrued and apportioned among the participating funds based on their average daily unused portion of the line of credit. The Funds paid certain legal fees in connection with the line of credit agreement, which are being amortized over a period of 364 days and are reflected in legal fees on the Statements of Operations. The unamortized balance is reflected as prepaid expenses on the Statements of Assets and Liabilities.

For the year ended December 31, 2022, neither Fund had borrowings under this agreement.

9. **Risk.** Russia's military invasion of Ukraine in February 2022, the resulting responses by the United States and other countries, and the potential for wider conflict could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. These and any related events could significantly impact a Fund's performance and the value of an investment in the Fund, even if the Fund does not have direct exposure to Russian issuers or issuers in other countries affected by the invasion.

10. **Concentration of Ownership.** From time to time, a Fund may have a concentration of one or more accounts constituting a significant percentage of shares outstanding. Investment activities by holders of such accounts could have material impacts on the Funds. As of December 31, 2022, based on management's evaluation of the shareholder account base, the Funds had accounts representing controlling ownership of more than 5% of the Fund's total outstanding shares. The number of such accounts, based on accounts that represent more than 5% of an individual class of shares, and the aggregate percentage of net assets represented by such holdings were as follows:

---

| | | |
|:---|:---|:---|
| **Fund** | **Number of 5%<br>Account Holders** | **Percentage of<br>Ownership** |
|  Investment Grade Fixed Income Fund | 9 | 77.83% |

---

Omnibus shareholder accounts for which Natixis Advisors understands that the intermediary has discretion over the underlying shareholder accounts or investment models where a shareholder account may be invested for a non-discretionary customer are included in the table above. For other omnibus accounts, the Fund does not have information on the individual shareholder accounts underlying the omnibus accounts; therefore, there could be other 5% shareholders in addition to those disclosed in the table above.

**Report of Independent Registered Public Accounting Firm** 

To the Board of Trustees of Loomis Sayles Funds I and Shareholders of Loomis Sayles Bond Fund and Loomis Sayles Investment Grade Fixed Income Fund

***Opinions on the Financial Statements***

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Loomis Sayles Bond Fund and Loomis Sayles Investment Grade Fixed Income Fund (two of the funds constituting Loomis Sayles Funds I, hereafter collectively referred to as the "Funds") as of December 31, 2022, the related statements of operations for the year ended December 31, 2022, the statements of changes in net assets for each of the two years in the period ended December 31, 2022, including the related notes, and the financial highlights for each of the two years in the period ended December 31, 2022, the three month period ended December 31, 2020 and for each of the three years in the period ended September 30, 2020 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of December 31, 2022, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended December 31, 2022, and each of the financial highlights for each of the two years in the period ended December 31, 2022, the three month period ended December 31, 2020 and for each of the three years in the period ended September 30, 2020 in conformity with accounting principles generally accepted in the United States of America.

***Basis for Opinions***

These financial statements are the responsibility of the Funds' management. Our responsibility is to express an opinion on the Funds' financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of December 31, 2022 by correspondence with the custodian, agent banks and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

**ACT OF 2002 FOR PRINCIPAL EXECUTIVE AND SENIOR FINANCIAL** 

**OFFICERS** 

**I.** **Covered Persons/Purpose of the Code** 

This Code of Ethics (this "Code") pursuant to Section 406 of the Sarbanes-Oxley Act of 2002 has been adopted by the registered investment companies (each a "Fund" and, collectively, the "Funds") listed on Exhibit A and applies to each Fund's Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer (the "Covered Persons," all covered persons are set forth in Exhibit B) for the purpose of promoting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between
personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Full, fair, accurate, timely, and understandable disclosure in reports and documents that a registrant files
with, or submits to, the Securities and Exchange Commission (the "SEC") and in other public communications made by the registrant

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Compliance with applicable governmental laws, rules and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the
Code of violations of the Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Accountability for adherence to the Code.

Each Covered Person should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to conflicts of interest.

------

**II.** **Covered Persons Should Handle Ethically Actual and Apparent Conflicts of Interest** 

**Overview.** A "conflict of interest" occurs when a Covered Person's private interest interferes with the interests of, or his service to, the Fund. For example, a conflict of interest would arise if a Covered Person's, or a member of the Covered Person's family or household, receives improper personal benefits as a result of the Covered Person's position with the Fund.

Certain conflicts of interest arise out of the relationships between Covered Persons and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940 (including the regulations thereunder, the "1940 Act") and the Investment Advisers Act of 1940 (including the regulations thereunder, the "Investment Advisers Act"). For example, Covered Persons may not engage in certain transactions with the Fund because of their status as "affiliated persons" of the Fund. The Funds and their investment advisers; subadvisers; distributors and administrators (each a "Service Provider" and, collectively, the "Service Providers") compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code. See also Section V of this code.

Although typically not presenting an opportunity for improper personal benefit, conflicts may arise from, or as a result of, the contractual relationship between the Funds and their Service Providers of which the Covered Persons are also officers or employees. As a result, this Code recognizes that the Covered Persons will, in the normal course of their duties (whether for the Funds or for a Service Provider, or for each), be involved in establishing policies and implementing decisions that will have different effects on the Service Providers and the Funds. The participation of the Covered Persons in such activities is inherent in the contractual relationships between the Funds and their Service Providers and is consistent with the performance by the Covered Persons of their duties as officers of the Funds. Thus, if performed in conformity with the provisions of the 1940 Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the Funds' Boards of Trustees ("Boards") that the Covered Persons may also be officers or employees of one or more other investment companies covered by this or other codes and that such service, by itself, does not give rise to a conflict of interest.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not the subject of provisions of the 1940 Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Persons should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Person should not be placed improperly before the interest of a Fund.

------

Each Covered Person must not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• use his/her personal influence or personal relationships improperly to influence investment decisions or
financial reporting by a Fund whereby the Covered Person would benefit personally to the detriment of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cause a Fund to take action, or fail to take action, for the individual personal benefit of the Covered Person
rather than the benefit the Fund; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• retaliate against any other Covered Person or any employee of the Funds or their Service Providers for reports of
potential violations that are made in good faith.

There are some conflict of interest situations that should always be approved by the Chief Legal Officer ("CLO") of the Fund (or, with respect to activities of the CLO if he/she is a Covered Person, by the President). These conflict of interest situations are listed below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• service on the board of directors or governing board of a publicly traded entity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acceptance of any investment opportunity, gift, gratuity or other thing of more than nominal value from any
person or entity that does business, or desires to do business, with the Fund. This restriction shall not apply to (i) gifts from a single giver so long as their aggregate annual value does not exceed the equivalent of $100 or
(ii) attending business meals, business related conferences, sporting events and other entertainment events at the expense of a giver, so long as the expense is reasonable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any ownership interest in, or any consulting relationship with, any entities doing business with a Fund, other
than a Service Provider or an affiliate of a Service Provider. This restriction shall not apply to or otherwise limit the ownership of publicly traded securities so long as the Covered Person's ownership does not exceed more than 2% of the
outstanding securities of the relevant class; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a direct or indirect financial interest in commissions, transaction charges or spreads paid by a Fund for
effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Person's employment with a Service Provider or its affiliate. This restriction shall not apply to or otherwise limit
(i) the ownership of publicly traded securities so long as the Covered Person's ownership does not exceed more than 2% of the particular class of security outstanding or (ii) the receipt by the Service Provider of research or other
benefits in exchange for "soft dollars".

------

**III.** **Disclosure and Compliance** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each Covered Person should familiarize himself with the disclosure requirements generally applicable to a Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each Covered Person should not knowingly misrepresent, or cause others to misrepresent, facts about a Fund to
others, whether within or outside the Fund, including to the Fund's Board and auditors, and to governmental regulators and self-regulatory organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each Covered Person should, to the extent appropriate within his/her area of responsibility, consult with other
officers and employees of the Funds and the adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Funds file with, or submit to, the SEC and in other public communications made
by the Funds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It is the responsibility of each Covered Person to promote compliance with the standards and restrictions imposed
by applicable laws, rules and regulations.

**IV.** **Reporting and Accountability** 

Each Covered Person must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Person), affirm in writing to the
Funds that he/she has received, read, and understands the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• annually thereafter affirm to the Funds that he/she has complied with the requirements of the Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• notify the CLO of the Funds promptly if he/she knows of any violation of this Code (with respect to violations by
the CLO if he/she is a Covered Person, the Covered Person shall report to the President). Failure to do so is itself a violation of this Code.

The CLO of a Fund is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. However, any approvals or waivers other than those this Code states can be granted by the CLO, sought by the CLO or Covered Person will be considered by the relevant Fund's Audit Committee (the "Committee").

The Funds will follow these procedures in investigating and enforcing this Code:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the CLO will take all appropriate action to investigate any potential violations reported, which may include the
use of internal or external counsel, accountants or other personnel;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, after such investigation, the CLO believes that no violation has occurred, the CLO is not required to take
any further action;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any matter that the CLO believes is a violation will be reported to the Committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the Committee concurs that a violation has occurred, it will inform and make a recommendation to the Board,
which will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to dismiss
the Covered Person;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Committee will be authorized to grant waivers, as it deems appropriate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

**V.** **Other Policies and Procedures** 

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Funds or the Funds' Service Providers govern or purport to govern the behavior or activities of the Covered Persons who are subject to this Code, they are superseded by this Code to the extent that they conflict with the provisions of this Code. The Funds and their Service Providers' codes of ethics under Rule 17j-1 under the 1940 Act and the Service Providers' more detailed compliance policies and procedures are separate requirements applying to the Covered Persons and others, and are not part of this Code.

**VI.** **Amendments** 

Any amendments to this Code with respect to a Fund, other than administrative amendments to Exhibits A and B, must be approved or ratified by a majority vote of the Fund's Board, including a majority of independent trustees.

**VII.** **Confidentiality** 

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone except as permitted by the Board.

------

**VIII.** **Internal Use** 

The Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Fund, as to any fact, circumstance, or legal conclusion.
