Performance data shown represents past performance and is no guarantee of, and not necessarily indicative of, future results. Total return and value will vary, and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. For most recent month-end performance, visit loomissayles.com. Performance for other share classes will be greater or less than shown based on differences in fees and sales charges. You may not invest directly in an index. Performance for periods less than one year is cumulative, not annualized. Returns reflect changes in share price and reinvestment of dividends and capital gains, if any. The table(s) do not reflect taxes shareholders might owe on any fund distributions or when they redeem their shares.

The Bloomberg Barclays U.S. Government/Credit Bond Index is the non-securitized component of the U.S. Aggregate Index and was the first macro index launched by Barclays Capital. The U.S. Government/Credit Bond Index includes investment grade, U.S. dollar-denominated, fixed-rate Treasuries (i.e., public obligations of the U.S. Treasury that have remaining maturities of more than one year), government-related issues (i.e., agency, sovereign, supranational, and local authority debt), and corporate securities. The U.S. Government/Credit Index was launched on January 1, 1979, with index history backfilled to 1973, and is a subset of the Bloomberg Barclays U.S. Aggregate Index.

Fund performance has been increased by fee waivers and/or expense reimbursements, if any, without which performance would have been lower.

Expense ratios are as shown in the Fund’s prospectus in effect as of the date of this report. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report under Ratios to Average Net Assets. Net expenses reflect contractual expense limitations set to expire on 1/31/21. When a Fund’s expenses are below the limitation, gross and net expense ratios will be the same. See Note 6 of the Notes to Financial Statements for more information about the Fund’s expense limitations.

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 fees (12b-1 fees), and other fund expenses. Certain exemptions may apply. These costs are described in more detail in each Fund’s prospectus. The following examples are intended to help you understand the ongoing costs of investing in the Funds and help you compare these with the ongoing costs of investing in other mutual funds.

The first line in the table for each class of Fund shares shows the actual amount of Fund expenses you would have paid on a $1,000 investment in the Fund from October 1, 2019 through March 31, 2020. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example $8,600 account value divided by $1,000 = 8.60) and multiply the result by the number in the Expenses Paid During Period column as shown below for your class.

The second line in the table 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

March 31, 2020 (Unaudited)

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

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

Each Fund is a diversified investment company.

Each Fund offers Institutional Class shares. Global Bond Fund and Inflation Protected Securities Fund also offer Retail Class shares and Class N shares.

Each share class is sold without a sales charge. Retail Class shares pay a Rule 12b-1 fee. 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 Global Bond Fund and Inflation Protected Securities Fund and $3,000,000 for Fixed Income Fund, Institutional High Income Fund and 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. 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 transfer agent fees are borne collectively for Institutional Class and Retail 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 period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds’ financial statements.

a. Valuation. Fund securities and other investments are valued at market value based on market quotations obtained or determined by independent pricing services recommended by the adviser and approved by the Board of Trustees. Fund securities and other investments for which market quotations are not readily available are valued at fair value as determined in good faith by the adviser pursuant to procedures approved by the Board of Trustees, as described below. Market value is determined as follows:

Debt securities and unlisted preferred equity securities are valued based on evaluated bids furnished to the Funds by an independent pricing service or bid prices obtained from broker-dealers. Senior loans are valued at bid prices supplied by an independent pricing service, if available. Listed equity securities (including shares of closed-end investment companies and exchange-traded funds) are valued at the last sale price quoted on the exchange 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. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking an NOCP, at the most recent bid quotations on the applicable NASDAQ Market. Unlisted equity securities (except unlisted preferred equity securities) are 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 valued using evaluated bids furnished by an independent pricing service, if available. In some foreign markets, an official close price and a last sale price may be available from the foreign exchange or market. In those cases, the official close price is used. Broker-dealer bid prices may be used to value debt and unlisted equity securities and senior loans where an independent pricing service is unable to price a security or where an independent pricing service does not provide a reliable price for the security. Forward foreign currency contracts are valued utilizing interpolated rates determined based on information provided by an independent pricing service. Futures contracts are valued at the most recent settlement price on the exchange on which the adviser believes that, over time, they are traded most extensively. Swaptions are valued at

March 31, 2020 (Unaudited)

mid prices (between the bid and the ask price) supplied by an independent pricing service, if available. Other swaptions not priced through an independent pricing service are valued based on quotations obtained from broker-dealers. Centrally cleared credit default swap agreements are valued at settlement prices of the clearing house on which the contracts were traded or prices obtained from broker-dealers. Bilateral credit default swaps are valued based on mid prices (between the bid price and the ask price) supplied by an independent pricing service.

Fund securities and other investments for which market quotations are not readily available are valued at fair value as determined in good faith by the adviser pursuant to procedures approved by the Board of Trustees. The Funds may also value securities and other investments at fair value 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 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 its securities or other investments, the Funds may, among other things, use modeling tools or other processes that may take into account factors such as securities or other market activity and/or significant events that occur after the close of the foreign market and before the time the Fund’s net asset value (“NAV”) is calculated. Fair value pricing may require subjective determinations about the value of a security, 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 securities. In addition, the use of fair value pricing may not always result in adjustments to the prices of securities held by a Fund.

Illiquid securities for which market quotations are readily available and have been evaluated by the adviser are considered and classified as fair valued securities pursuant to the Funds’ pricing policies and procedures.

As of March 31, 2020, securities held by the Funds were fair valued as follows:


Fund	Securities classified as fair valued		Percentage of Net Assets		Securities fair valued by the Fund’s adviser		Percentage of Net Assets
Fixed Income Fund	$	11,776,845		1.9%	$	1,387,195		0.2%
Institutional High Income Fund		13,264,231		2.9%		467,267		0.1%
Investment Grade Fixed Income Fund		10,662,806		4.6%		9,143		Less than 0.1%

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, is 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. Interest income is increased by the accretion of discount and decreased by the amortization of premium, if applicable. Periodic principal adjustments for inflation-protected securities are recorded to interest income. Negative principal adjustments (in the event of deflation) are recorded as reductions of interest income to the extent of interest income earned, not to exceed the amount of positive principal adjustments on a cumulative basis. Distributions received from investments in securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments or as a realized gain, respectively. The calendar year-end amounts of ordinary income, capital gains, and return of capital included in distributions received from the Funds’ investments in real estate investment trusts (“REITs”) are reported to the Funds after the end of the fiscal year; accordingly, the Funds estimate these amounts for accounting purposes until the characterization of REIT distributions is reported to the Funds after the end of the fiscal year. Estimates are based on the most recent REIT distribution information available. 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 on the Funds’ books 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 or eliminate the amount of income available to be distributed by the Funds.

March 31, 2020 (Unaudited)

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 or eliminate the amount of income available to be distributed by the Funds.

For the six months ended March 31, 2020, the amount of income available to be distributed by Investment Grade Fixed Income Fund has been reduced by $387,537.

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. Certain Funds may enter into forward foreign currency contracts, including forward foreign cross currency contracts, to acquire exposure to foreign currencies or to hedge the Funds’ 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 Funds’ or counterparty’s net obligations under the contracts.

e. Futures Contracts. The Funds 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.

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 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. Swaptions. Certain Funds may enter into interest rate swaptions. An interest rate swaption gives the holder the right, but not the obligation, to enter into or cancel an interest rate swap agreement at a future date. Interest rate swaptions may be either purchased or written. The buyer of an interest rate swaption may purchase either the right to receive a fixed rate in the underlying swap (known as a “receiver swaption”) or to pay a fixed rate (known as a “payer swaption”), based on the notional amount of the swap agreement, in exchange for a floating rate. The notional amounts of swaptions are not recorded in the financial statements.

When a Fund purchases an interest rate swaption, it pays a premium and the swaption is subsequently marked-to-market to reflect current value. Premiums paid for purchasing interest rate swaptions which expire are treated as realized losses. Premiums paid for purchasing interest rate swaptions which are exercised are added to the cost or deducted from the proceeds on the underlying swap to determine the realized gain or loss. If a Fund enters into a closing sale transaction, the difference between the premium paid and the proceeds of the closing sale transaction is treated as a realized gain or loss. The risk associated with purchasing interest rate swaptions is limited to the premium paid.

When a Fund writes an interest rate swaption, an amount equal to the premium received is recorded as a liability and is subsequently adjusted to the current value. Premiums received for written interest rate swaptions which expire are treated as realized gains. Premiums received for written interest rate swaptions which are exercised are deducted from the cost or added to the proceeds on the underlying swap to determine the realized gain or loss. If a Fund enters into a closing purchase transaction, the difference between the premium received and any amount paid on effecting a closing purchase transaction, including commission, is treated as a realized gain or, if the premium received is less than the amount paid, as a realized loss. A Fund, as writer of a written interest rate swaption, bears the risk of an unfavorable change in the market value of the swap underlying the written interest rate swaption.

March 31, 2020 (Unaudited)

Over-the-counter interest rate swaptions are subject to the risk that the counterparty is unable or unwilling to meet its obligations under the swaption.

No swaptions were held by the Funds during the six months ended March 31, 2020.

g. Swap Agreements. The Funds may enter into credit default and interest rate swaps. A credit default swap is an agreement between two parties (the “protection buyer” and “protection seller”) to exchange the credit risk of an issuer (“reference obligation”) for a specified time period. The reference obligation may be one or more debt securities or an index of such securities. The Funds may be either the protection buyer or the protection seller. As a protection buyer, the Funds have the ability to hedge the downside risk of an issuer or group of issuers. As a protection seller, the Funds have the ability to gain exposure to an issuer or group of issuers whose bonds are unavailable or in short supply in the cash bond market, as well as realize additional income in the form of fees paid by the protection buyer. The protection buyer is obligated to pay the protection seller a stream of payments (“fees”) over the term of the contract, provided that no credit event, such as a default or a downgrade in credit rating, occurs on the reference obligation. The Funds may also pay or receive upfront premiums. If a credit event occurs, the protection seller must pay the protection buyer the difference between the agreed upon notional value and market value of the reference obligation. Market value in this case is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the value. The maximum potential amount of undiscounted future payments that a Fund as the protection seller could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement.

An interest rate swap is an agreement with another party to receive or pay interest (e.g., an exchange of fixed rate payments for floating rate payments) to protect themselves from interest rate fluctuations. This type of swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to a specified interest rate(s) for a specified notional amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other.

The notional amounts of swap agreements are not recorded in the financial statements. Swap agreements are valued daily and fluctuations in the value are recorded in the Statements of Operations as change in unrealized appreciation (depreciation) on swap agreements. Fees are accrued in accordance with the terms of the agreement and are recorded in the Statements of Assets and Liabilities as fees receivable or payable. When received or paid, fees are recorded in the Statements of Operations as realized gain or loss. Upfront premiums paid or received by the Funds are recorded on the Statements of Assets and Liabilities as an asset or liability, respectively, and are amortized or accreted over the term of the agreement and recorded as realized gain or loss. Payments made or received by the Funds as a result of a credit event or termination of the agreement are recorded as realized gain or loss.

Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (“centrally cleared swaps”). Bilateral swap agreements are traded between counterparties and, as such, are subject to the risk that a party to the agreement will not be able to meet its obligations. In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (the “CCP”) and the Fund faces the CCP through a broker. Upon entering into a centrally cleared swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Subsequent payments, known as “variation margin,” are made or received by the Fund based on the daily change in the value of the centrally cleared swap agreement. For centrally cleared swaps, the Fund’s counterparty credit risk is reduced as the CCP stands between the Fund and the counterparty. The Funds cover their net obligations under outstanding swap agreements by segregating or earmarking cash or securities.

No swap agreements were held by the Funds during the six months ended March 31, 2020.

h. When-Issued and Delayed Delivery Transactions. The Funds 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 at the custodian.

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.

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

There were no when-issued or delayed delivery securities held by the Funds as of March 31, 2020.

i. Federal and Foreign Income Taxes. The Trust treats each Fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2020 and has concluded that no provisions for income tax are required. The Funds’ federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

A Fund may be subject to foreign 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 eligible to be reclaimed. 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 will be filed 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.

j. 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 distribution re-designations, foreign currency gains and losses, convertible bonds, paydown gains and losses, premium amortization, return of capital distributions received, defaulted and/or non-income producing securities, interest rate swaps, capital gains taxes, contingent payment debt instruments, treasury inflation-protected bonds and deferred Trustees’ fees. Permanent book and tax basis differences relating to shareholder distributions 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, straddle loss deferrals, wash sales, convertible bonds, premium amortization, forward foreign currency contract mark-to-market, futures contract mark to market, trust preferred securities, return of capital distributions received, contingent payment debt instruments, corporate actions, and defaulted and/or non-income producing securities. 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 year ended September 30, 2019 was as follows:


	2019 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Fixed Income Fund	$	37,783,514	$	6,273,120	$	44,056,634
Global Bond Fund		2,303,295		3,049,750		5,353,045
Inflation Protected Securities Fund		562,130		—		562,130
Institutional High Income Fund		39,012,284		7,881,060		46,893,344
Investment Grade Fixed Income Fund		5,468,364		4,090,610		9,558,974

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.

Under current tax law, net operating losses, capital losses, foreign currency losses, losses on passive foreign investment companies and contingent payment debt instruments after October 31 or December 31, as applicable, may be deferred and treated as occurring on the first day of the following taxable year. Fixed Income Fund is deferring foreign currency losses.

As of March 31, 2020, unrealized appreciation (depreciation) on a tax basis was approximately as follows:


Unrealized appreciation (depreciation)	Fixed Income Fund			Global Bond Fund			Inflation Protected Securities Fund		Institutional High Income Fund			Investment Grade Fixed Income Fund
Investments	$	(46,205,753	)	$	(3,823,175	)	$	687,213	$	(13,802,502	)	$	5,110,809
Foreign currency translations		(30,325,992	)		(15,351,268	)		—		(110,912,207	)		(12,737,981	)

Total unrealized appreciation (depreciation)	$	(76,531,745	)	$	(19,174,443	)	$	687,213	$	(124,714,709	)	$	(7,627,172	)

As of March 31, 2020, the tax cost of investments (including derivatives, if applicable) and unrealized appreciation (depreciation) on a federal tax basis were as follows:


	Fixed Income Fund			Global Bond Fund			Inflation Protected Securities Fund			Institutional High Income Fund			Investment Grade Fixed Income Fund
Federal tax cost	$	688,517,328		$	671,496,389		$	47,311,019		$	572,736,307		$	238,028,782

Gross tax appreciation	$	40,827,340		$	23,647,374		$	1,054,741		$	22,628,862		$	15,294,043
Gross tax depreciation		(117,224,602	)		(42,737,699	)		(367,518	)		(147,273,717	)		(22,859,607	)

Net tax appreciation (depreciation)	$	(76,397,262	)	$	(19,090,325	)	$	687,223		$	(124,644,855	)	$	(7,565,564	)

The difference between these amounts and those reported in the preceding table are primarily attributable to foreign currency mark-to-market.

Amounts in the tables above exclude certain adjustments that will be made at the end of the Fund’s fiscal year for tax purposes. Adjustments may include, but are not limited to, wash sales and derivatives mark-to-market.

k. Senior Loans. Each Fund may invest in senior loans 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. Senior loans outstanding at the end of the period, if any, are listed in each applicable Fund’s Portfolio of Investments.

l. Loan Participations. A Fund’s investments in senior loans may be in the form of participations in loans. When investing in a loan participation, a Fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the party from whom the Fund has purchased the participation and only upon receipt by that party of payments from the borrower. A Fund generally has no right to enforce compliance by the borrower with the terms of the loan agreement or to vote on matters arising under the loan agreement. Thus, a Fund may be subject to credit risk from both the party from whom it purchased the loan participation and the borrower. Additionally, a Fund may have minimal control over the terms of any loan modification. Loan participations outstanding at the end of the period, if any, are listed in each applicable Fund’s Portfolio of Investments.

There were no loan participations held by the Funds as of March 31, 2020.

m. 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 March 31, 2020, 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.

n. Due to/from Brokers. Transactions and positions in certain futures, forward foreign currency contracts and swap agreements are maintained and cleared by registered U.S. broker/dealers pursuant to customer agreements between a Fund and the various broker/dealers. The due to brokers balance in the Statements of Assets and Liabilities for Global Bond Fund represents cash received as collateral for forward foreign currency contracts. The due from brokers balance in the Statements of Assets and Liabilities for Global Bond Fund represents cash pledged as collateral for forward foreign currency contracts and as initial margin for futures contracts. The due from brokers balance in the Statement of Assets and Liabilities for Inflation Protected Securities Fund represents cash pledged as initial margin for futures contracts. In certain circumstances a Fund’s use of cash and/or securities held at brokers is restricted by regulation or broker mandated limits.

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

For the six months ended March 31, 2020, none of the Funds had loaned securities under this agreement.

p. 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.

q. New Accounting Pronouncement. In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update introduces new fair value disclosure requirements, eliminates some prior fair value disclosure requirements, and modifies certain existing fair value disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt any eliminated or modified disclosures upon issuance of the update and delay adoption of any new disclosures until the required effective date. Management has evaluated the impact of the adoption of ASU 2018-13 and has determined to early adopt the removal of (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the policy for timing of transfers between levels. New disclosures required by ASU 2018-13 will be incorporated in the Funds’ semiannual financial statements as of March 31, 2021.

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

•

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

•

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

| 60

March 31, 2020 (Unaudited)

•

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 and procedures are recommended by the adviser and approved by the Board of Trustees. Debt securities are valued based on evaluated bids furnished to the Funds by an independent pricing service. Broker-dealer bid prices may be used if an independent pricing service either is unable to price a security or does not provide a reliable price for a security. The Funds’ adviser may use internally developed models to validate broker-dealer bid prices that are only available from a single broker or market maker. Such securities are considered and classified as fair valued. Broker-dealer bid prices for which the Funds do not have knowledge of the inputs used by the broker-dealer are categorized in Level 3. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Funds’ adviser pursuant to procedures approved by the Board of Trustees. Fair valued securities may be categorized in Level 3.

The following is a summary of the inputs used to value the Funds’ investments as of March 31, 2020, at value:

At March 31, 2020, this security was valued using broker-dealer bid prices based on inputs unobservable to the Fund as an independent pricing service did not provide a reliable price for the security.

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 Global Bond Fund and Inflation Protected Securities Fund used during the period include forward foreign currency contracts and futures contracts.

Global Bond Fund is 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 Fund may enter into forward foreign currency exchange contracts for hedging purposes to protect the value of the Funds’ holdings of foreign securities. The Fund 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 Fund. During the six months ended March 31, 2020, Global Bond Fund engaged in forward foreign currency transactions for hedging purposes and to gain exposure to foreign currencies.

Global Bond Fund and Inflation Protected Securities Fund are subject to the risk that changes in interest rates will affect the value of the Funds’ investments in fixed-income securities. A Fund will be subject to increased interest rate risk to the extent that it invests in fixed-income securities with longer maturities or durations, as compared to investing in fixed-income securities with shorter maturities or durations. The Funds may use futures contracts to hedge against changes in interest rates and to manage duration without having to buy or sell portfolio securities. Inflation Protected Securities Fund may use futures contracts to gain investment exposure. During the six months ended March 31, 2020, Global Bond Fund and Inflation Protected Securities Fund used futures contracts for hedging purposes and to manage duration.

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 Global Bond Fund and Inflation Protected Securities Fund 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 six months ended March 31, 2020:


Global Bond Fund	Forwards		Futures
Average Notional Amount Outstanding		18.19%		19.65%
Highest Notional Amount Outstanding		23.40%		22.91%
Lowest Notional Amount Outstanding		14.59%		16.58%
Notional Amount Outstanding as of March 31, 2020		22.70%		19.33%


Inflation Protected Securities Fund		Futures
Average Notional Amount Outstanding		2.15%
Highest Notional Amount Outstanding		5.55%
Lowest Notional Amount Outstanding		0.00%
Notional Amount Outstanding as of March 31, 2020		0.00%

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 forwards and futures is recorded in the Statements of Assets and Liabilities. The aggregate notional values of forward and futures contracts are not recorded in the Statements of Assets and Liabilities, and therefore are not included in the Funds’ net assets.

Over-the-counter derivatives, including forward foreign currency contracts, are entered into pursuant to International Swaps and Derivatives Association, Inc. (“ISDA”) agreements negotiated between the Funds and their counterparties. ISDA agreements typically contain, among other things, terms for the posting of collateral and master netting provisions in the event of a default or other termination event. Collateral is posted by a Fund or the counterparty to the extent of the net mark-to-market exposure to the other party of all open contracts under the agreement, subject to minimum transfer requirements. Master netting provisions allow the Funds and the counterparty, in the event of a default or other termination event, to offset amounts owed by each related to derivative contracts, including any posted collateral, to one net amount payable by either the Funds or the counterparty. The Funds’ ISDA agreements typically contain provisions that allow a counterparty to terminate open contracts early if the NAV of a Fund declines beyond a certain threshold. For financial reporting purposes, the Funds do not offset derivative assets and liabilities, and any related collateral received or pledged, on the Statements of Assets and Liabilities.

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 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 are required to segregate customer margin 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 clients, 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 March 31, 2020:


Fund	Maximum Amount of Loss – Gross		Maximum Amount of Loss – Net
Global Bond Fund	$	9,803,735	$	7,319,774
Inflation Protected Securities Fund		45,000		45,000

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.

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 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 $199,000. 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 Trust based on a formula that takes into account, among other factors, the relative net assets of each fund. Trustees are reimbursed for travel expenses in connection with attendance at meetings.

Prior to January 1, 2020, the Chairperson of the Board received a retainer fee at the annual rate of $360,000 and each Independent Trustee (other than the Chairperson) received, in the aggregate, a retainer fee at the annual rate of $190,000, and the chairperson of the Governance Committee received an additional retainer fee at the annual rate of $15,000. All other Trustee fees remained unchanged.

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

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

8. Line of Credit. Each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trust, entered into a $400,000,000 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 $400,000,000 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 an arrangement fee, an upfront fee, and certain other 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 and/or miscellaneous expenses on the Statements of Operations. The unamortized balance is reflected as prepaid expenses on the Statements of Assets and Liabilities.

For the six months ended March 31, 2020, none of the Funds had borrowings under this agreement.

9. Risk. Certain Funds’ investments in foreign securities may be subject to greater political, economic, environmental, credit/counterparty and information risks. The Funds’ investments in foreign securities also are subject to foreign currency fluctuations and other foreign currency-related risks. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity.

Global markets have experienced periods of high volatility triggered by the rapidly evolving public health emergency known as coronavirus (“COVID-19”). As the situation continues to unfold, the extent and duration of the impact that the COVID-19 outbreak may have on financial markets and the economy as a whole remains highly uncertain. If the effects of the COVID-19 outbreak on financial markets and the economy continue for an extended period of time, the Funds’ future financial and investment results may be adversely affected.

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 March 31, 2020, 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% Non- Affiliated Account Holders		Percentage of Non- Affiliated Ownership		Percentage of Affiliated Ownership (Note 6f)		Total Percentage of Ownership

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 Funds do 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.

Investment Objective

The Fund’s investment objective is high current income. Capital appreciation is the Fund’s secondary objective.

Average Annual Total Returns — March 31, 2020



													Expense Ratios²
	6 Months			1 Year			5 Years			10 Years			Gross			Net

Institutional Class (Inception 4/12/04)		-9.55	%		-7.22	%		2.86	%		6.15	%		0.00	%		0.00	%

Comparative Performance
Bloomberg Barclays U.S. Corporate High-Yield Bond Index¹		-10.40			-6.94			2.78			5.64

Performance data shown represents past performance and is no guarantee of, and not necessarily indicative of, future results. Total return and value will vary, and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. Performance for other share classes will be greater or less than shown based on differences in fees and sales charges. You may not invest directly in an index. Performance for periods less than one year is cumulative, not annualized. Returns reflect changes in share price and reinvestment of dividends and capital gains, if any. The table(s) do not reflect taxes shareholders might owe on any fund distributions or when they redeem their shares.

Bloomberg Barclays U.S. Corporate High-Yield Bond Index measures the market of USD-denominated, non-investment grade, fixed-rate, taxable corporate bonds. Securities are classified as high yield if the middle rating of Moody’s, Fitch, and S&P is Ba1/BB+/BB+ or below, excluding emerging market debt. The U.S. Corporate High-Yield Bond Index was created in 1986, with history backfilled to July 1, 1983, and rolls up into the Barclays U.S. Universal and Global High-Yield Indices.

The amount shown under Gross and Net Expense Ratio is 0.00% to reflect the fact that the Fund does not pay any advisory, administration or distribution and service fees, and that Loomis Sayles has agreed to pay certain expenses of the Fund. All fees are paid by investors indirectly through separately negotiated advisory relationships with the Fund’s Adviser or through “wrap fee” programs sponsored by broker dealers and investment advisers that may be affiliated or unaffiliated with the Fund, Loomis Sayles or Natixis Advisors, L.P.

UNDERSTANDING FUND EXPENSES

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

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

The first line in each Fund’s table shows the actual amount of Fund expenses ($0) you would have paid on a $1,000 investment in the Fund from October 1, 2019 through March 31, 2020.

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 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.

The implied credit spread of a particular reference entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Notes to Financial Statements

March 31, 2020 (Unaudited)

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

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

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

Each Fund is a diversified investment company.

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

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 period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds’ financial statements.

Debt securities and unlisted preferred equity securities are valued based on evaluated bids furnished to the Funds by an independent pricing service or bid prices obtained from broker-dealers. Senior loans and collateralized loan obligations are valued at bid prices supplied by an independent pricing service, if available. Listed equity securities (including shares of closed-end investment companies and exchange-traded funds) are valued at the last sale price quoted on the exchange 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. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking an NOCP, at the most recent bid quotations on the applicable NASDAQ Market. Unlisted equity securities (except unlisted preferred equity securities) are 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 valued using evaluated bids furnished by an independent pricing service, if available. In some foreign markets, an official close price and a last sale price may be available from the foreign exchange or market. In those cases, the official close price is used. Broker-dealer bid prices may be used to value debt and unlisted equity securities and senior loans and collateralized loan obligations where an independent pricing service is unable to price a security or where an independent pricing service does not provide a reliable price for the security. Forward foreign currency contracts are valued utilizing interpolated rates determined based on information provided by an independent pricing service. Futures contracts are valued at the most recent settlement price on the exchange on which the adviser believes that, over time, they are traded most extensively. Centrally cleared credit default swap agreements are valued at settlement prices of the clearing house on which the contracts were traded or prices obtained from broker-dealers. Bilateral credit default swaps are valued based on mid prices (between the bid price and the ask price) supplied by an independent pricing service. Centrally cleared swap agreements are valued at settlement prices of the clearing house on which the contracts were traded or prices obtained from broker-dealers.

March 31, 2020 (Unaudited)

As of March 31, 2020, securities held by the Funds were fair valued as follows:


Fund	Securities classified as fair valued		Percentage of Net Assets		Securities fair valued by the Fund’s adviser		Percentage of Net Assets
High Income Opportunities Fund	$	2,057,817		1.4%	$	204,347		0.1%
Securitized Asset Fund		8,562,483		0.6%		23,186,882		1.6%

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.

d. Forward Foreign Currency Contracts. The Funds may enter into forward foreign currency contracts, including forward foreign cross currency contracts, to acquire exposure to foreign currencies or to hedge the Funds’ 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 Funds’ or counterparty’s net obligations under the contracts.

No forward foreign currency contracts were held by the Funds during the six months ended March 31, 2020.

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.

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

Implied credit spreads, represented in absolute terms, are disclosed in the Portfolio of Investments for those agreements for which the Fund is the protection seller. Implied credit spreads serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular reference entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

The notional amounts of swap agreements are not recorded in the financial statements. Swap agreements are valued daily, and fluctuations in value are recorded in the Statements of Operations as change in unrealized appreciation (depreciation) on swap agreements. Fees are accrued in accordance with the terms of the agreement and are recorded in the Statements of Assets and Liabilities as fees receivable or payable. When received or paid, fees are recorded in the Statements of Operations as realized gain or loss. Upfront premiums paid or received by the Funds are recorded on the Statements of Assets and Liabilities as an asset or liability, respectively, and are amortized or accreted over the term of the agreement and recorded as realized gain or loss. Payments made or received by the Funds as a result of a credit event or termination of the agreement are recorded as realized gain or loss.

g. When-Issued and Delayed Delivery Transactions. The Funds 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.

h. Stripped Securities. Each Fund may invest in stripped securities, which are usually structured with two or more classes that receive different proportions of the interest and principal distribution on a pool of U.S. or foreign government securities or mortgage assets. In some cases, one class will receive all of the interest (the interest-only or “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). Stripped securities commonly have greater market volatility than other types of fixed-income securities. In the case of stripped mortgage securities, if the underlying mortgage assets experience greater than anticipated prepayments of principal, a Fund may fail to recoup fully its investments in IOs.

i. 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 investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2020 and has concluded that no provisions for income tax are required. The Funds’ federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

j. 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 premium amortization, contingent payment debt instruments, interest rate swaps, defaulted bonds and/or non-income producing securities, distribution re-designations, convertible bonds and paydown gains and losses. Permanent book and tax basis differences relating to shareholder distributions 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 wash sales, premium amortization, defaulted bonds and/or non-income producing securities, contingent payment debt instruments, convertible bonds, futures contracts mark-to-market and swap adjustments. 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 characterization of distributions paid to shareholders during the year ended September 30, 2019 was as follows:


	2019 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
High Income Opportunities Fund	$	9,838,729	$	850,076	$	10,688,805
Securitized Asset Fund		64,801,602		—		64,801,602

| 42

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

As of September 30, 2019, capital loss carryforwards were as follows:


	High Income Opportunities Fund			Securitized Asset Fund
Capital loss carryforward:
Short-term:
No expiration date	$	—		$	(1,164,884	)
Long-term:
No expiration date		(706,200	)		(49,368,347	)

Total capital loss carryforward	$	(706,200	)	$	(50,533,231	)

As of March 31, 2020, the tax cost of investments (including derivatives) and unrealized appreciation (depreciation) on a federal tax basis were as follows:


	High Income Opportunities Fund			Securitized Asset Fund
Federal tax cost	$	172,621,826		$	1,625,911,282

Gross tax appreciation	$	1,910,401		$	38,031,092
Gross tax depreciation		(25,270,630	)		(101,816,730	)

Net tax depreciation	$	(23,360,229	)	$	(63,785,638	)

Amounts in the table above exclude certain adjustments that will be made at the end of the Fund’s fiscal year for tax purposes. Adjustments may include, but are not limited to, wash sales and derivatives mark-to-market.

m. Collateralized Loan Obligations. Each 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 collateral securities and the class of the instrument in which a Fund invests. The intent of the Funds when investing in CLOs is to purchase only higher level, investment grade level select tranches. CLOs outstanding at the end of the period, if any, are listed in each applicable Fund’s Portfolio of Investments.

n. 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

43 |

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

of the counterparty, including possible delays or restrictions upon a Fund’s ability to dispose of the underlying securities. As of March 31, 2020, 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.

o. Due to/from Brokers. Transactions and positions in certain futures contracts, swap agreements and delayed delivery commitments are maintained and cleared by registered U.S. broker/dealers pursuant to customer agreements between the Funds and the various broker/dealers. The due from brokers balance in the Statements of Assets and Liabilities for High Income Opportunities Fund represents cash pledged as initial margin for centrally cleared swap agreements. The due from brokers balance for Securitized Asset Fund represents cash pledged as initial margin for futures contracts and centrally cleared swap agreements. The due to brokers balance for Securitized Asset Fund represents cash received as collateral for delayed delivery securities. In certain circumstances the Fund’s use of cash held at brokers is restricted by regulation or broker mandated limits.

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

For the six months ended March 31, 2020, neither Fund had loaned securities under this agreement.

q. 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.

r. New Accounting Pronouncement. In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update introduces new fair value disclosure requirements, eliminates some prior fair value disclosure requirements, and modifies certain existing fair value disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt any eliminated or modified disclosures upon issuance of the update and delay adoption of any new disclosures until the required effective date. Management has evaluated the impact of the adoption of ASU 2018-13 and has determined to early adopt the removal of (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the policy for timing of transfers between levels. New disclosures required by ASU 2018-13 will be incorporated in the Funds’ semiannual financial statements as of March 31, 2021.

internally developed models to validate broker-dealer bid prices that are only available from a single broker or market maker. Such securities are considered and classified as fair valued. Broker-dealer bid prices for which the Funds do not have knowledge of the inputs used by the broker-dealer are categorized in Level 3. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Funds’ adviser pursuant to procedures approved by the Board of Trustees. Fair valued securities may be categorized in Level 3.

¹“Odd lot” securities (those with current principal below the normal trading size) are valued using a discount to the “round lot” price for the same security. The significant unobservable input used in the fair value measurement is the discount rate. Discount rates are set at a specific fixed rate depending on the size of the odd lot. The Unobservable Input Value(s) noted above reflect a range due to the fact that there are multiple odd lot securities within each asset type that have had different discount rates applied. A significant change in the discount rate could have had a material effect on the fair value measurement. There is an inverse relationship between the discount rate and the fair value measurement, meaning a significant increase in the discount rate would have resulted in a lower fair value measurement, and vice versa.

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 futures contracts and swap agreements.

High Income Opportunities Fund is subject to the risk that companies in which the Fund invests will fail financially or otherwise be unwilling or unable to meet their obligations to the Fund. The Fund may use credit default swaps, as a protection buyer, to hedge its credit exposure to issuers of bonds it holds without having to sell the bonds. The Fund may also use credit default swaps, as a protection seller, to gain investment exposure. During the six months ended March 31, 2020, the Fund engaged in credit default swap transactions (as a protection seller) to gain investment exposure.

Securitized Asset Fund is subject to the risk that changes in interest rates will affect the value of the Fund’s investments in fixed-income securities. The Fund will be subject to increased interest rate risk to the extent that it invests in fixed-income securities with longer maturities or durations, as compared to investing in fixed-income securities with shorter maturities or durations. The Fund may use futures contracts and interest rate swaps to hedge against changes in interest rates and to manage duration without having to buy or sell portfolio securities. During the six months ended March 31, 2020, Securitized Asset Fund used futures contracts to hedge against changes in interest rates and used both futures contracts and interest rate swaps to manage duration.

The following is a summary of derivative instruments for High Income Opportunities Fund as of March 31, 2020, as reflected within the Statements of Assets and Liabilities:


Liabilities	Swap agreements at value¹
Exchange-traded/cleared liability derivatives Credit contracts	$	(205,440	)

¹ Represents swap agreements, at value. Market value of swap agreements is reported in the Portfolio of Investments along with the unamortized upfront premium paid (received), if any, and unrealized appreciation (depreciation) on each individual contract.

Transactions in derivative instruments for High Income Opportunities Fund during the six months ended March 31, 2020 as reflected in the Statements of Operations were as follows:


Net Realized Gain (Loss) on:		Swap agreements
Credit contracts		$136,833

Net Change in Unrealized Appreciation (Depreciation) on:		Swap agreements
Credit contracts		$(33,794)

The following is a summary of derivative instruments for Securitized Asset Fund as of March 31, 2020, as reflected within the Statements of Assets and Liabilities:

¹ Represents cumulative unrealized appreciation (depreciation) on futures contracts. Only the current day’s variation margin on futures contracts is reported within the Statements of Assets and Liabilities as receivable or payable for variation margin, as applicable.

² Represents swap agreements, at value. Only the current day’s variation margin on swap agreements is reported within the Statements of Assets and Liabilities as receivable or payable for variation margin, as applicable.

Transactions in derivative instruments for Securitized Asset Fund during the six months ended March 31, 2020 as reflected in the Statements of Operations were as follows:


Net Realized Gain (Loss) on:	Futures contracts			Swap agreements
Interest rate contracts	$	(4,972,655	)	$	(39,668	)

Net Change in Unrealized Appreciation (Depreciation) on:	Futures contracts			Swap agreements
Interest rate contracts	$	(12,288,775	)	$	(9,733,834	)

The volume of futures contract and swap agreement activity, as a percentage of net assets, based on gross month-end notional amounts outstanding during the period, including long and short positions at absolute value, was as follows for the six months ended March 31, 2020:


High Income Opportunities Fund			Credit Default Swaps
Average Notional Amount Outstanding				0.27%
Highest Notional Amount Outstanding				2.10%
Lowest Notional Amount Outstanding				0.00%
Notional Amount Outstanding as of March 31, 2020				2.10%

Securitized Asset Fund	Futures		Interest Rate Swaps
Average Notional Amount Outstanding		12.02%		10.55%
Highest Notional Amount Outstanding		20.71%		12.79%
Lowest Notional Amount Outstanding		6.07%		8.95%
Notional Amount Outstanding as of March 31, 2020		20.71%		11.36%

Notional amounts outstanding at the end of the prior period, if applicable, are included in the averages above.

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

Counterparty risk is managed based on policies and procedures established by the 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. 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 are required to segregate customer margin 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 clients, 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 the maximum amount of loss due to credit risk that, based on the gross fair value of the financial instrument, the applicable Fund would incur if parties (including 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:


Fund	Maximum Amount of Loss – Gross		Maximum Amount of Loss – Net
High Income Opportunities Fund	$	615,468	$	615,468
Securitized Asset Fund		10,429,227		10,429,227

6. Management Fees and Other Transactions with Affiliates.

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

Loomis Sayles serves as investment adviser to each Fund. Loomis Sayles is a limited partnership whose sole general partner, Loomis, Sayles & Company, Inc., is indirectly owned by Natixis Investment Managers, LLC (“Natixis”), which is part of Natixis Investment Managers, an international asset management group based in Paris, France. Under the terms of each management agreement, Loomis Sayles does not charge the Funds an investment advisory fee, also known as a management fee, or any other fee for those services or for bearing those expenses. Although the Funds do not compensate Loomis Sayles directly for services under the advisory agreement, Loomis Sayles will typically receive an advisory fee from the sponsors of “wrap programs,” who in turn charge the programs’ participants.

b. Service and Distribution Fees. Natixis Distribution, L.P. (“Natixis Distribution”), which is a wholly-owned subsidiary of Natixis, 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. Natixis Distribution currently is not paid a fee for serving as distributor for the Funds. Loomis Sayles has agreed to reimburse Natixis Distribution to the extent that Natixis Distribution incurs expenses in connection with any redemption of Fund shares.

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

d. Trustees Fees and Expenses. The Trust does not pay any compensation directly to its officers or Trustees who are directors, officers or employees of Natixis Advisors, Natixis Distribution, Natixis 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 $199,000. 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 Trust 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. Loomis Sayles has agreed to pay, without reimbursement from the Trust or Funds, Trustees fees and expenses allocable to the Funds.

March 31, 2020 (Unaudited)

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

7. Line of Credit. Each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trust, entered into a $400,000,000 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 $400,000,000 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 (applicable allocations to the Funds are paid by Loomis Sayles) based on their average daily unused portion of the line of credit. Loomis Sayles, on behalf of the Funds, paid an arrangement fee, an upfront fee, and certain other legal fees in connection with the line of credit agreement.

For the six months ended March 31, 2020, neither Fund had borrowings under this agreement.

8. Payable to Custodian Bank. The Funds’ custodian bank, State Street Bank, provides overdraft protection to the Funds in the event of a cash shortfall. Cash overdrafts bear interest at a rate per annum equal to the Federal Funds rate plus 2.00%. At March 31, 2020, High Income Opportunities Fund and Securitized Asset Fund had payables to the custodian bank of $320,122 and $3,522,875, for overdrafts due to derivative and redemption activity, respectively.

9. Risk. Securitized Asset Fund’s investments in mortgage-related and asset-backed securities are subject to certain risks not associated with investments in other securities. Mortgage-related and asset-backed securities are subject to the risk that unexpected changes in interest rates will have a direct effect on expected maturity. A shortened maturity may result in the reinvestment of prepaid amounts in securities with lower yields than the original obligations. An extended maturity may result in a reduction of a security’s value.

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 March 31, 2020, 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 fund shares, and the aggregate percentage of net assets represented by such holdings were as follows:


Fund	Number of 5% Account Holders	Percentage of Ownership
High Income Opportunities Fund	4	95.26%
Securitized Asset Fund	4	97.53%

Indices are unmanaged.

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 Funds’ prospectus. The following examples are intended to help you understand the ongoing costs of investing in the Funds and help you compare these with the ongoing costs of investing in other mutual funds.

The first line in the table of each Fund shows the actual amount of Fund expenses you would have paid on a $1,000 investment in the Fund from October 1, 2019 through March 31, 2020. 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

7 |

multiply the result by the number in the Expenses Paid During Period column as shown below for your class.

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

Notes to Financial Statements

March 31, 2020 (Unaudited)

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

Loomis Sayles Funds I:

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

Loomis Sayles Funds II:

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

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

Each Fund is a diversified investment company.

Small Cap Growth Fund offers Institutional Class, Retail Class and Class N shares. Small Cap Value Fund offers Institutional Class, Retail Class, Admin Class and Class N shares. Small/Mid Cap Growth Fund offers Institutional Class and Class N shares (effective October 1, 2019).

Each share class is sold without a sales charge. Retail Class and Admin Class shares pay a Rule 12b-1 fee. 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. Certain categories of investors are exempted from the minimum investment amount for Class N and Institutional Class as outlined in the relevant Fund’s prospectus. Admin Class shares are offered exclusively through intermediaries.

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”), Loomis Sayles Funds I and Loomis Sayles Funds II (“Loomis Sayles Funds Trusts”), and Natixis ETF 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 (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.

| 40

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

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 period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds’ financial statements.

Listed equity securities (including shares of closed-end investment companies and exchange-traded funds) are valued at the last sale price quoted on the exchange 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. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking an NOCP, at the most recent bid quotations on the applicable NASDAQ Market. Unlisted equity securities (except unlisted preferred equity securities) are 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 valued using evaluated bids furnished by an independent pricing service, if available. In some foreign markets, an official close price and a last sale price may be available from the foreign exchange or market. In those cases, the official close price is used. Debt securities and unlisted preferred equity securities are valued based on evaluated bids furnished to the Funds by an independent pricing service or bid prices obtained from broker-dealers. Broker-dealer bid prices may be used to value debt and unlisted equity securities where an independent pricing service is unable to price a security or where an independent pricing service does not provide a reliable price for the security.

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 its securities or other investments, the Funds may, among other things, use modeling tools or other processes that may take into account factors such as securities or other market activity and/or significant events that occur after the close of the foreign market and before the time the Fund’s net asset value (“NAV”) is calculated. Fair value pricing may require subjective determinations about the value of a security, 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 securities. In addition, the use of fair value pricing may not always result in adjustments to the prices of securities 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, is 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. Interest income is increased by the accretion of discount and decreased by the amortization of premium, if applicable. Distributions received from investments in securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments or as a realized gain, respectively. The calendar year-end amounts of ordinary income, capital gains and return of capital included in distributions received from the Funds’ investments in real estate investment trusts (“REITs”) are reported to the Funds after the end of the fiscal year; accordingly, the Funds estimate these amounts for accounting purposes until the characterization of REIT distributions is reported to the Funds after the end of the fiscal year. Estimates are based on the most recent REIT distribution information available. 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.

recorded on the Funds’ books 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.

d. 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 of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2020 and has concluded that no provisions for income tax are required. The Funds’ federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

e. Dividends and Distributions to Shareholders. Dividends and distributions are recorded on 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 return of capital distributions received, deferred Trustees’ fees, and net operating losses. Permanent book and tax basis differences relating to shareholder distributions 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 return of capital distributions received, deferred Trustees’ fees and wash sales. 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 year ended September 30, 2019 was as follows:


	2019 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Small Cap Growth Fund	$	—	$	131,384,945	$	131,384,945
Small Cap Value Fund		1,761,169		110,774,229		112,535,398
Small/Mid Cap Growth Fund		—		4,717,064		4,717,064

As of September 30, 2019, late-year ordinary and post-October capital loss deferrals were as follows:



	Small Cap Growth Fund			Small Cap Value Fund		Small/Mid Cap Growth Fund
Late-year ordinary and post-October capital loss deferrals*	$	(6,292,971	)	$	—	$	(67,038	)

Under current tax law, net operating losses, capital losses, foreign currency losses, and losses on passive foreign investment companies and contingent payment debt instruments after October 31 or December 31, as applicable, may be deferred and treated as occurring on the first day of the following taxable year. Small Cap Growth Fund and Small/Mid Cap Growth Fund are deferring net operating losses.

As of March 31, 2020, the tax cost of investments and unrealized appreciation (depreciation) on a federal tax basis were as follows:


	Small Cap Growth Fund			Small Cap Value Fund			Small/Mid Cap Growth Fund
Federal tax cost	$	1,415,647,846		$	466,663,484		$	36,338,150

Gross tax appreciation	$	219,261,762		$	85,291,418		$	1,407,633
Gross tax depreciation		(174,003,483	)		(102,947,336	)		(4,583,674	)

Net tax appreciation (depreciation)	$	45,258,279		$	(17,655,918	)	$	(3,176,041	)

Amounts in the table above exclude certain adjustments that will be made at the end of the Fund’s fiscal year for tax purposes. Such adjustments are primarily due to wash sales.

f. 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 March 31, 2020, 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.

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

For the six months ended March 31, 2020, none of the Funds had loaned securities under this agreement.

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

i. New Accounting Pronouncement. In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update introduces new fair value disclosure requirements, eliminates some prior fair value disclosure requirements, and modifies certain existing fair value disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt any eliminated or modified disclosures upon issuance of the update and delay adoption of any new disclosures until the required effective date. Management has evaluated the impact of the adoption of ASU 2018-13 and has determined to early adopt the removal of (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the policy for timing of transfers between levels. New disclosures required by ASU 2018-13 will be incorporated in the Funds’ semiannual financial statements as of March 31, 2021.

In addition, the Admin Class shares of Small Cap Value 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.

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 six months ended March 31, 2020, the sub-transfer agent fees (which are reflected in transfer agent fees and expenses in the Statements of Operations) for each Fund were as follows:


Fund	Sub-Transfer Agent Fees
Small Cap Growth Fund	$	661,169
Small Cap Value Fund		280,424

Small Cap Value Fund		5,138

March 31, 2020 (Unaudited)

and all transfer agency expenses for the Fund’s Class N shares. This undertaking is in effect through January 31, 2021 and is not subject to recovery under the expense limitation agreement described above.

For the six months ended March 31, 2020, Natixis Advisors reimbursed Small/Mid Cap Growth Fund $730 for transfer agency expenses related to Class N shares.

6. Class-Specific Transfer Agent Fees and Expenses. Transfer agent fees and expenses 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. Transfer agent fees and expenses attributable to Class N are allocated to Class N.

For the six months ended March 31, 2020, the Funds incurred the following class-specific transfer agent fees and expenses (including sub-transfer agent fees, where applicable):


	Transfer Agent Fees and Expenses
Fund	Institutional Class		Retail Class		Admin Class		Class N
Small Cap Growth Fund	$	605,803	$	62,253	$	—	$	3,185

Small/Mid Cap Growth Fund		2,440		—		—		730

7. Line of Credit. Each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trust, entered into a $400,000,000 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 $400,000,000 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 an arrangement fee, an upfront fee, and certain other 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 and/or miscellaneous expenses on the Statements of Operations. The unamortized balance is reflected as prepaid expenses on the Statements of Assets and Liabilities.

For the six months ended March 31, 2020, none of the Funds had borrowings under this agreement.

8. 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 March 31, 2020, based on management’s evaluation of the shareholder account base, the Funds had accounts representing controlling ownership of more than

53 |

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

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% Account Holders		Percentage of Ownership
Small Cap Value Fund		1		7.42%
Small/Mid Cap Growth Fund		5		68.09%

9. Risk. Global markets have experienced periods of high volatility triggered by the rapidly evolving public health emergency known as coronavirus (“COVID-19”). As the situation continues to unfold, the extent and duration of the impact that the COVID-19 outbreak may have on financial markets and the economy as a whole remains highly uncertain. If the effects of the COVID-19 outbreak on financial markets and the economy continue for an extended period of time, the Funds’ future financial and investment results may be adversely affected.

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

11. Redemption In-Kind. In certain circumstances, a Fund may distribute portfolio securities rather than cash as payment for redemption of Fund shares (redemption in-kind). For financial reporting purposes, the Fund will recognize a gain on in-kind redemptions to the extent the value of the distributed securities on the date of redemption exceeds the cost of those securities; the Fund will recognize a loss if the cost exceeds value. Gains and losses realized on redemptions in-kind are not recognized for tax purposes, and are re-classified from realized gain (loss) to paid-in-capital. Small/Mid Cap Growth Fund realized a gain of $779,521 on redemptions in-kind during the six months ended March 31, 2020. This amount is included in realized gain (loss) on the Statements of Operations.

Performance data shown represents past performance and is no guarantee of, and not necessarily indicative of, future results. Total return and value will vary, and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. For most recent month-end performance, visit loomissayles.com. Performance for other share classes will be greater or less than shown based on differences in fees and sales charges. You may not invest directly in an index. Performance for periods less than one year is cumulative, not annualized. Returns reflect changes in share price and reinvestment of dividends and capital gains, if any. The table(s) do not reflect taxes shareholders might owe on any fund distributions or when they redeem their shares.

Bloomberg Barclays US Government/Credit Bond Index is the non-securitized component of the US Aggregate Index and was the first macro index launched by Barclays Capital. The US Government/Credit Bond Index includes Treasuries (i.e., public obligations of the US Treasury that have remaining maturities of more than one year), government-related issues (i.e., agency, sovereign, supranational, and local authority debt), and corporates. The US Government/Credit Index was launched on January 1, 1979, with index history backfilled to 1973, and is a subset of the US Aggregate Index.

Fund performance has been increased by fee waivers and/or expense reimbursements, if any, without which performance would have been lower.

Expense ratios are as shown in the Fund’s prospectus in effect as of the date of this report. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report under Ratios to Average Net Assets. Net expenses reflect contractual expense limitations set to expire on 1/31/21. When a Fund’s expenses are below the limitation, gross and net expense ratios will be the same. See Note 5 of the Notes to Financial Statements for more information about the Fund’s expense limitations.

Notes to Financial Statements

March 31, 2020 (Unaudited)

1. Organization. Loomis Sayles Funds I (the “Trust”) is organized as a Massachusetts business trust. The Trust is registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as an open-end management investment company. The Declaration of Trust permits the Board of Trustees to authorize the issuance of an unlimited number of shares of the Trust in multiple series. The financial statements for certain funds of the Trust are presented in separate reports. Information presented in these financial statements pertains to Loomis Sayles Bond Fund (the “Fund”).

The Fund is a diversified investment company.

The Fund offers Institutional Class, 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. Certain categories of investors are exempted from the minimum investment amounts for Class N and Institutional Class as outlined in the 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. Expenses of the Fund are borne pro rata by the holders of each class of shares, except that each class bears expenses unique to that class (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 the 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 the Fund in the preparation of its financial statements. The Fund’s 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 period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Fund’s financial statements.

Debt securities and unlisted preferred equity securities are valued based on evaluated bids furnished to the Fund by an independent pricing service or bid prices obtained from broker-dealers. Senior loans are valued at bid prices supplied by an independent pricing service, if available. Listed equity securities (including shares of closed-end investment companies and exchange-traded funds) are valued at the last sale price quoted on the exchange 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. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking an NOCP, at the most recent bid quotations on the applicable NASDAQ Market. Unlisted equity securities (except unlisted preferred equity securities) are 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 valued using evaluated bids furnished by an independent pricing service, if available. In some foreign markets, an official close price and a last sale price may be available from the foreign exchange or market. In those cases, the official close price is used. Broker-dealer bid prices may be used to value debt and unlisted equity securities and senior loans where an independent pricing service is unable to price a security or where an independent pricing service does not provide a reliable price for the security.

Fund securities and other investments for which market quotations are not readily available are valued at fair value as determined in good faith by the adviser pursuant to procedures approved by the Board of Trustees. The Fund may also value securities and other investments at fair value 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 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 its securities or other investments, the Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities or other market activity and/or significant events that occur after the close of the foreign market and before the time the Fund’s net asset value (“NAV”) is calculated. Fair value pricing may require subjective determinations about the value of a security, 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 securities. In addition, the use of fair value pricing may not always result in adjustments to the prices of securities held by the Fund.

As of March 31, 2020, securities held by the Fund were fair valued as follows:


Securities classified as fair valued	Percentage of Net Assets	Securities fair valued by the Fund’s adviser	Percentage of Net Assets
$425,546,673	4.9%	$23,434,480	0.3%

c. Foreign Currency Translation. The books and records of the Fund 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 on the Fund’s books 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 Statement of Operations. For federal income tax purposes, net realized foreign exchange gains or losses are characterized as ordinary income and may, if the Fund has net losses, reduce the amount of income available to be distributed by the Fund.

March 31, 2020 (Unaudited)

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 Statement 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 Statement of Operations, may be characterized as ordinary income and may, if the Fund has net losses, reduce the amount of income available to be distributed by the Fund.

During the six months ended March 31, 2020, the amount of income available to be distributed by the Fund has been reduced by $38,991,428 as a result of losses arising from changes in exchange rates.

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

d. When-Issued and Delayed Delivery Transactions. The 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 Fund at the time the commitment is entered into. The value of the security may vary with market fluctuations during the time before the Fund takes delivery of the security. No interest accrues to the Fund 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 Fund or counterparty to post cash and/or securities as collateral for the net mark-to-market exposure to the other party. The Fund covers its net obligations under outstanding delayed delivery commitments by segregating or earmarking cash or securities at the custodian.

Purchases of when-issued or delayed delivery securities may have a similar effect on the Fund’s NAV as if the Fund 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 Fund as of March 31, 2020.

e. Federal and Foreign Income Taxes. The Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of the Fund’s tax positions for the open tax years as of March 31, 2020 and has concluded that no provisions for income tax are required. The Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Fund. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

The Fund may be subject to foreign 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 Statement of Operations as a reduction of investment income, net of amounts eligible to be reclaimed. Dividends and interest receivable on the Statement of Assets and Liabilities are net of foreign withholding taxes. Foreign withholding taxes where reclaims have been or will be filed are reflected on the Statement of Assets and Liabilities as tax reclaims receivable. Capital gains taxes paid are included in net realized gain (loss) on investments in the Statement of Operations. Accrued but unpaid capital gains taxes are reflected as foreign taxes payable on the Statement 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 the Fund. Such amounts, if applicable, are reflected as foreign tax rebates receivable on the Statement of Assets and Liabilities and are recorded as a realized gain when received.

f. 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 foreign currency gains and losses, defaulted and/or non-income producing securities, deferred Trustees’ Fees, partnership basis adjustments, premium amortization, convertible bonds and paydown gains and losses. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts reported on the Statement of Assets and Liabilities. Temporary differences between book

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

and tax distributable earnings are primarily due to deferred Trustees’ fees, wash sales, premium amortization, convertible bonds, defaulted and/or non-income producing securities, return of capital distributions received, trust preferred securities, partnership basis adjustments, corporate actions and contingent payment debt instruments. Amounts of income and capital gain available to be distributed on a tax basis are determined annually, and at other times during the Fund’s fiscal year as may be necessary to avoid knowingly declaring and paying a return of capital distribution. Distributions from net investment income and short-term capital gains are considered to be distributed from ordinary income for tax purposes.

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended September 30, 2019 was as follows:


2019 Distributions Paid From:
Ordinary Income	Long-Term Capital Gains	Total
$402,223,224	$36,170,163	$438,393,387

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 Statement 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 March 31, 2020, unrealized appreciation (depreciation) on a tax basis was approximately as follows:


Unrealized appreciation (depreciation)
Investments	$	(896,363,262	)
Foreign currency translations		(765,726,863	)

Total unrealized depreciation	$	(1,662,090,125	)

As of March 31, 2020, the tax cost of investments and unrealized appreciation (depreciation) on a federal tax basis were as follows:


Federal tax cost	$	10,281,105,971

Gross tax appreciation	$	462,899,496
Gross tax depreciation		(2,121,679,249	)

Net tax depreciation	$	(1,658,779,753	)

The difference between these amounts and those reported in the preceding table are primarily attributable to foreign currency mark-to-market.

Amounts in the tables above exclude certain adjustments that will be made at the end of the Fund’s fiscal year for tax purposes. Adjustments may include, but are not limited to, wash sales.

g. Senior Loans. The Fund may invest in senior loans 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. The 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. Senior loans outstanding at the end of the period are listed in the Fund’s Portfolio of Investments.

h. Repurchase Agreements. The Fund may enter into repurchase agreements, under the terms of a Master Repurchase Agreement, under which the Fund acquires securities as collateral and agrees to resell the securities at an agreed upon time and at an agreed upon price. It is the Fund’s policy that the market value of the collateral for repurchase agreements be at least equal to 102% of the repurchase price, including interest. Certain repurchase agreements are tri-party arrangements whereby the collateral is held in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon the Fund’s ability to dispose of the underlying securities. As of March 31, 2020, the Fund 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 Statement of Assets and Liabilities for financial reporting purposes.

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

33 |

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

may bear the risk of loss with respect to the investment of the collateral. The Fund invests cash collateral in short-term investments, a portion of the income from which is remitted to the borrowers and the remainder allocated between the Fund and State Street Bank as lending agent.

For the six months ended March 31, 2020, the Fund did not loan securities under this agreement.

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

k. New Accounting Pronouncement. In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update introduces new fair value disclosure requirements, eliminates some prior fair value disclosure requirements, and modifies certain existing fair value disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt any eliminated or modified disclosures upon issuance of the update and delay adoption of any new disclosures until the required effective date. Management has evaluated the impact of the adoption of ASU 2018-13 and has determined to early adopt the removal of (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the policy for timing of transfers between levels. New disclosures required by ASU 2018-13 will be incorporated in the Fund’s semiannual financial statements as of March 31, 2021.

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

•

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

•

Level 3—prices determined using significant unobservable inputs when quoted prices or observable inputs are unavailable such as when there is little or no market activity

| 34

Notes to Financial Statements – continued

March 31, 2020 (Unaudited)

for an asset or liability (unobservable inputs reflect the Fund’s own assumptions in determining the fair value of assets or liabilities and would be based on the best information available).

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

The Fund’s pricing policies and procedures are recommended by the adviser and approved by the Board of Trustees. Debt securities are valued based on evaluated bids furnished to the Fund by an independent pricing service. Broker-dealer bid prices may be used if an independent pricing service either is unable to price a security or does not provide a reliable price for a security. The Fund’s adviser may use internally developed models to validate broker-dealer bid prices that are only available from a single broker or market maker. Such securities are considered and classified as fair valued. Broker-dealer bid prices for which the Fund does not have knowledge of the inputs used by the broker-dealer are categorized in Level 3. Securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Fund’s adviser pursuant to procedures approved by the Board of Trustees. Fair valued securities may be categorized in Level 3.

The following is a summary of the inputs used to value the Fund’s investments as of March 31, 2020, at value:

March 31, 2020 (Unaudited)

Under the terms of the management agreement, the Fund pays a management fee at the following annual rates, calculated daily and payable monthly, based on the Fund’s average daily net assets:


Percentage of Average Daily Net Assets
First $3 billion	Next $12 billion	Next $10 billion	Over $25 billion
0.60%	0.50%	0.49%	0.48%

Loomis Sayles has given a binding undertaking to the Fund to waive management fees and/or reimburse certain expenses to limit the Fund’s operating expenses, exclusive of acquired fund fees and expenses, brokerage expenses, interest expense, taxes, organizational and extraordinary expenses such as litigation and indemnification expenses. This undertaking is in effect until January 31, 2021, may be terminated before then only with the consent of the Fund’s Board of Trustees and is reevaluated on an annual basis. Management fees payable, as reflected on the Statement of Assets and Liabilities, is net of waivers and/or expense reimbursements, if any, pursuant to this undertaking. Waivers/reimbursements that exceed management fees payable are reflected on the Statement of Assets and Liabilities as receivable from investment adviser.

For the six months ended March 31, 2020, the expense limits as a percentage of average daily net assets under the expense limitation agreement were as follows:


Expense Limit as a Percentage of Average Daily Net Assets
Institutional Class	Retail Class	Admin Class	Class N
0.67%	0.92%	1.17%	0.62%

Loomis Sayles shall be permitted to recover expenses borne under the expense limitation agreement (whether through waiver of management fees or otherwise) on a class by class basis in later periods to the extent the annual operating expenses of a class fall below a class’ expense limits, provided, however, that a class is not obligated to pay such waived/reimbursed fees or expenses more than one year after the end of the fiscal year in which the fees or expenses were waived/reimbursed.

For the six months ended March 31, 2020, the management fees for the Fund were $27,318,748 (effective rate of 0.53% of average daily net assets).

No expenses were recovered during the six months ended March 31, 2020 under the terms of the expense limitation agreement.

b. Service and Distribution Fees. Natixis Distribution, L.P. (“Natixis Distribution”) which is a wholly-owned subsidiary of Natixis, 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.

March 31, 2020 (Unaudited)

Pursuant to Rule 12b-1 under the 1940 Act, the Trust 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, the 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, the 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 the 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 six months ended March 31, 2020, the service and distribution fees for the Fund were as follows:


Service Fees	Distribution Fees
Admin Class	Retail Class	Admin Class
$96,684	$2,408,934	$96,684

c. Administrative Fees. Natixis Advisors, L.P. (“Natixis Advisors”) provides certain administrative services for the Fund and contracts with State Street Bank to serve as sub-administrator. Natixis Advisors is a wholly-owned subsidiary of Natixis.

Administrative Fees

$2,265,038

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 Fund and has agreed to compensate the intermediaries for providing those services. Intermediaries transact with the Fund primarily through the use of omnibus accounts on behalf of their customers who hold positions in the Fund. These services would have been provided by the Fund’s transfer agent and other service providers if the shareholders’ accounts were maintained directly at the Fund’s transfer agent. Accordingly, the Fund has 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 Fund’s Board of Trustees, which is based on fees for similar services paid to the Fund’s transfer agent and other service providers. Class N shares do not bear such expenses.

For the six months ended March 31, 2020, the sub-transfer agent fees (which are reflected in transfer agent fees and expenses in the Statement of Operations) for the Fund were $3,437,638.

As of March 31, 2020, the Fund owes Natixis Distribution $46,289 in reimbursements for sub-transfer agent fees (which are reflected in the Statement of Assets and Liabilities as payable to distributor).

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 Trust based on a formula that takes into account, among other factors, the relative net assets of each fund. Trustees are reimbursed for travel expenses in connection with attendance at meetings.

A deferred compensation plan (the “Plan”) is available to the Trustees on a voluntary basis. Deferred amounts remain in the Fund until distributed in accordance with the provisions of the Plan. The value of a participating Trustee’s deferral account is based on theoretical investments of deferred amounts, on the normal payment dates, in certain funds of the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trust 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 Trust, and are normally reflected as Trustees’ fees and expenses in the Statement of Operations. The portions of the accrued obligations allocated to the Fund under the Plan are reflected as Deferred Trustees’ fees in the Statement of Assets and Liabilities.

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

f. Affiliated Ownership. As of March 31, 2020, Loomis Sayles Employees’ Profit Sharing Retirement Plan held shares of the Fund representing 0.37% of the Fund’s net assets.

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

g. Affiliated Transactions. As a result of a business restructuring, the Fund received common stock shares of Bellatrix Exploration Ltd. (the “Company”) which constitutes more than 5% of the voting securities of the Company. As such, the Company is

6. Class-Specific Transfer Agent Fees and Expenses. Transfer agent fees and expenses 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 the six months ended March 31, 2020, the Fund incurred the following class-specific transfer agent fees and expenses (including sub-transfer agent fees, where applicable):


Transfer Agent Fees and Expenses
Institutional Class	Retail Class	Admin Class	Class N
$2,831,394	$714,486	$28,684	$12,405

7. Line of Credit. The Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trust, entered into a $400,000,000 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 $400,000,000 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 an arrangement fee, an upfront fee, and certain other 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 and/or miscellaneous expenses on the Statement of Operations. The unamortized balance is reflected as prepaid expenses on the Statement of Assets and Liabilities.

For the six months ended March 31, 2020, the Fund had no borrowings under this agreement.

8. Risk. The Fund’s investments in foreign securities may be subject to greater political, economic, environmental, credit/counterparty and information risks. The Fund’s investments in foreign securities also are subject to foreign currency fluctuations and other foreign currency-related risks. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity.

Global markets have experienced periods of high volatility triggered by the rapidly evolving public health emergency known as coronavirus (“COVID-19”). As the situation continues to unfold, the extent and duration of the impact that the COVID-19 outbreak may have on financial markets and the economy as a whole remains highly uncertain. If the effects of the COVID-19 outbreak on financial markets and the economy continue for an extended period of time, the Fund’s future financial and investment results may be adversely affected.

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

Performance data shown represents past performance and is no guarantee of, and not necessarily indicative of, future results. Total return and value will vary, and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. For most recent month-end performance, visit im.natixis.com. Performance for other share classes will be greater or less than shown based on differences in fees and sales charges. You may not invest directly in an index. Performance for periods less than one year is cumulative, not annualized. Returns reflect changes in share price and reinvestment of dividends and capital gains, if any. The table(s) do not reflect taxes shareholders might owe on any fund distributions or when they redeem their shares.

As of August 31, 2016, the Fund’s Retail Class shares and Institutional Class shares were redesignated as Class A shares and Class Y shares, respectively. Accordingly, the returns shown in the table for Class A shares prior to August 31, 2016 are those of Retail Class shares, restated to reflect the sales loads of Class A shares, and the returns in the table for Class Y shares prior to August 31, 2016 are those of Institutional Class shares. Prior to the inception of Retail Class shares (May 28, 2010), performance is that of Institutional Class shares, restated to reflect the higher net expenses and sales loads of Class A shares. Prior to the inception of Class C shares (August 31, 2016), performance is that of Retail Class shares, restated to reflect the higher net expenses and sales loads of Class C shares.

2	Class C shares performance assumes a 1% CDSC applied when you sell shares within one year of purchase.

The Bloomberg Barclays U.S. Intermediate Government/Credit Bond Index includes securities in the intermediate maturity range within the Government and Credit Indices. The Government Index includes treasuries (i.e., public obligations of the U.S. Treasury that have remaining maturities of more than one year) and agencies (i.e., publicly issued debt of U.S. Government agencies, quasi-federal corporations, and corporate or foreign debt guaranteed by the U.S. Government). The Credit Index includes publicly issued U.S. corporate and foreign debentures and secured notes that meet specified maturity, liquidity, and quality requirements.

4	The Fund revised its investment strategy on May 28, 2010; performance may have been different had the current investment strategy been in place for all periods shown.

5	Fund performance has been increased by fee waivers and/or expense reimbursements, if any, without which performance would have been lower.

UNDERSTANDING FUND EXPENSES

As a mutual fund shareholder, you incur different costs: transaction costs, including sales charges (loads) on purchases and contingent deferred sales charges on redemptions, and 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 Funds’ prospectus. The following examples are intended to help you understand the ongoing costs of investing in the Funds and help you compare these with the ongoing costs of investing in other mutual funds.

The first line in the table of each class of Fund shares shows the actual account values and actual Fund expenses you would have paid on a $1,000 investment in the Fund from October 1, 2019 through March 31, 2020. 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 of each class of Fund shares provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratios and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid on your investment for the period. You may use this information to compare the ongoing costs of investing in the Fund 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, such as sales charges. Therefore, the second line in the table of each fund is useful in comparing ongoing costs only, and will not help you determine the relative costs of owning different funds. If transaction costs were included, total costs would be higher.

March 31, 2020 (Unaudited)

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

Loomis Sayles Funds I:

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

Loomis Sayles Funds II:

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

Each Fund is a diversified investment company.

Each Fund offers Class A, Class C, Class N and Class Y shares.

Class A shares of Intermediate Duration Bond Fund are sold with a maximum front-end sales charge of 4.25%. Class A shares of Limited Term Government and Agency Fund are sold with a maximum front-end sales charge of 2.25%. Class C shares do not pay a front-end sales charge, pay higher Rule 12b-1 fees than Class A shares for 10 years (at which point they automatically convert to Class A shares) and may be subject to a contingent deferred sales charge (“CDSC”) of 1.00% if those shares are redeemed within one year of acquisition, except for reinvested distributions. Class N and Class Y shares do not pay a front-end sales charge, a CDSC or Rule 12b-1 fees. Class N shares are offered with an initial minimum investment of $1,000,000. Class Y shares are offered with an initial minimum investment of $100,000. Certain categories of investors are exempted from the minimum investment amounts for Class N and Class Y as outlined in the relevant Funds’ 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”), Loomis Sayles Funds I and Loomis Sayles Funds II (“Loomis Sayles Funds Trusts”), and Natixis ETF 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 (such as the Rule 12b-1 fees applicable to Class A and Class C) and transfer agent fees are borne collectively for Class A, Class C and Class Y, 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.

Debt securities and unlisted preferred equity securities are valued based on evaluated bids furnished to the Funds by an independent pricing service or bid prices obtained from broker-dealers. Listed equity securities (including shares of closed-end investment companies and exchange-traded funds) are valued at the last sale price quoted on the exchange 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. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking an NOCP, at the most recent bid quotations on the applicable NASDAQ Market. Unlisted equity securities (except unlisted preferred equity securities) are 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 valued using evaluated bids furnished by an independent pricing service, if available. In some foreign markets, an official close price and a last sale price may be available from the foreign exchange or market. In those cases, the official close price is used. Broker-dealer bid prices may be used to value debt and unlisted equity securities where an independent pricing service is unable to price a security or where an independent pricing service does not provide a reliable price for the security. Futures contracts are valued at the most

recent settlement price on the exchange on which the adviser believes that, over time, they are traded most extensively.

As of March 31, 2020, securities held by the Funds were fair valued as follows:


Fund	Securities fair valued by the Fund’s adviser		Percentage of Net Assets
Intermediate Duration Bond Fund	$	22,014		Less than 0.1	%
Limited Term Government and Agency Fund		1,449,890		0.2	%

interest income earned, not to exceed the amount of positive principal adjustments on a cumulative basis. 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.

d. Futures Contracts. The Funds 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.

51 |

Notes to Financial Statements (continued)

March 31, 2020 (Unaudited)

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.

e. When-Issued and Delayed Delivery Transactions. The Funds 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.

There were no when-issued or delayed delivery securities held by the Funds as of March 31, 2020.

f. 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 of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of March 31, 2020 and has concluded that no provisions for income tax are required. The Funds’ federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. Management is not aware of any events that are reasonably possible to occur in the next six months that would result in the amounts of any unrecognized tax benefits significantly increasing or decreasing for the Funds. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws and accounting regulations and interpretations thereof.

g. 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 deferred Trustees’ fees, premium amortization and paydown gains and losses. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to capital accounts. Temporary differences between book and tax distributable earnings are primarily due to deferred Trustees’ fees, wash sales, premium amortization and futures contract mark-to-market. Amounts of income and capital gain available to be

53 |

Notes to Financial Statements (continued)

March 31, 2020 (Unaudited)

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 year ended September 30, 2019 was as follows:


	2019 Distributions Paid From:
Fund	Ordinary Income		Long-Term Capital Gains		Total
Intermediate Duration Bond Fund	$	5,986,529	$	—	$	5,986,529
Limited Term Government and Agency Fund		16,591,331		—		16,591,331

As of September 30, 2019, capital loss carryforwards were as follows:


	Intermediate Duration Bond Fund		Limited Term Government and Agency Fund
Capital loss carryforward:
Short-term:
No expiration date	$	—	$	(1,558,729	)
Long-term:
No expiration date		—		(34,283,605	)

Total capital loss carryforward	$	—	$	(35,842,334	)

Notes to Financial Statements (continued)

March 31, 2020 (Unaudited)

As of March 31, 2020, the tax cost of investments (including derivatives, if applicable) and unrealized appreciation (depreciation) on a federal tax basis were as follows:


	Intermediate Duration Bond Fund			Limited Term Government and Agency Fund
Federal tax cost	$	237,003,513		$	864,903,067

Gross tax appreciation	$	4,424,946		$	22,904,538
Gross tax depreciation		(4,926,251	)		(5,642,696	)

Net tax appreciation (depreciation)	$	(501,305	)	$	17,261,842

h. 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 March 31, 2020, 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.

i. Due from Brokers. Transactions and positions in certain futures contracts are maintained and cleared by registered U.S. broker/dealers pursuant to customer agreements between the Funds and the various broker/dealers. The due from broker balance in the Statements of Assets and Liabilities for Intermediate Duration Bond Fund represents cash pledged as initial margin for futures contracts. In certain circumstances the Fund’s use of cash held at brokers is restricted by regulation or broker mandated limits.

j. Securities Lending. The Funds have entered into an agreement with State Street Bank and Trust Company (“State Street Bank”), as agent of the Funds, to lend securities to certain designated borrowers. The loans are collateralized with cash or securities in an amount equal to at least 105% or 102% of the market value (including

55 |

Notes to Financial Statements (continued)

March 31, 2020 (Unaudited)

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

For the six months ended March 31, 2020, neither Fund had loaned securities under this agreement.

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

l. New Accounting Pronouncement. In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update introduces new fair value disclosure requirements, eliminates some prior fair value disclosure requirements, and modifies certain existing fair value disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt any eliminated or modified disclosures upon issuance of the update and delay adoption of any new disclosures until the required effective date. Management has evaluated the impact of the adoption of ASU 2018-13 and has determined to early adopt the removal of (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the policy for timing of transfers between levels. New disclosures required by ASU 2018-13 will be incorporated in the Funds’ semiannual financial statements as of March 31, 2021.

3. Fair Value Measurements. In accordance with accounting standards related to fair value measurements and disclosures, the Funds have categorized the inputs utilized in

| 56

Notes to Financial Statements (continued)

March 31, 2020 (Unaudited)

determining the value of each Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

•

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

•

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

•

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.

A debt security valued at $23,495 was transferred from Level 2 to Level 3 during the period ended March 31, 2020. At September 30, 2019, this security was valued on the basis of evaluated bids furnished to the Fund by an independent pricing service in accordance with the Fund’s valuation policies. At March 31, 2020 this security was valued at fair value as determined in good faith by the Fund’s adviser as an independent pricing service did not provide a reliable price for the security.

At September 30, 2019, these securities were valued on the basis of evaluated bids furnished to the Fund by an independent pricing service in accordance with the Fund’s valuation policies. At March 31, 2020 these securities were valued at fair value as determined in good faith by the Fund’s adviser as an independent pricing service did not provide a reliable price for the securities.

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 Intermediate Duration Bond Fund used during the period include futures contracts.

| 60

Notes to Financial Statements (continued)

March 31, 2020 (Unaudited)

Intermediate Duration Bond Fund is subject to the risk that changes in interest rates will affect the value of the Fund’s investments in fixed-income securities. A Fund will be subject to increased interest rate risk to the extent that it invests in fixed-income securities with longer maturities or durations, as compared to investing in fixed-income securities with shorter maturities or durations. The Fund may use futures contracts to hedge against changes in interest rates and to manage its duration in order to control interest rate risk without having to buy or sell portfolio securities. During the six months ended March 31, 2020, Intermediate Duration Bond Fund used futures contracts to manage duration.

The following is a summary of derivative instruments for Intermediate Duration Bond Fund as of March 31, 2020, as reflected within the Statements of Assets and Liabilities:


Assets	Unrealized appreciation on futures contracts
Exchange-traded asset derivatives
Interest rate contracts	$	654,996

Liabilities	Unrealized depreciation on futures contracts
Exchange-traded liability derivatives
Interest rate contracts		$(9,415)

Transactions in derivative instruments for Intermediate Duration Bond Fund during the six months ended March 31, 2020, as reflected within the Statements of Operations, were as follows:


Net Realized Gain (Loss) on:	Futures contracts
Interest rate contracts	$	172,793

Net Change in Unrealized Appreciation (Depreciation) on:	Futures contracts
Interest rate contracts	$	759,925

As the Fund values its derivatives at fair value and recognizes changes in fair value through the Statement of Operations, it does not qualify for hedge accounting under authoritative guidance for derivative instruments. The Fund’s 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 futures contract activity, as a percentage of net assets, based on gross month-end notional amounts outstanding during the period, including long and short positions at absolute value, was as follows for the six months ended March 31, 2020:


Intermediate Duration Bond Fund	Futures
Average Notional Amount Outstanding		8.75	%

Lowest Notional Amount Outstanding		8.36	%
Notional Amount Outstanding as of March 31, 2020		10.58	%

Notional amounts outstanding at the end of the prior period 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.

Pursuant to Rule 12b-1 under the 1940 Act, the Trusts have adopted a Service Plan relating to each Fund’s Class A shares (the “Class A Plans”) and a Distribution and Service Plan relating to each Fund’s Class C shares (the “Class C Plans”).

Under the Class A Plans, each Fund pays Natixis Distribution a monthly service fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Fund’s Class A shares, as reimbursement for expenses incurred by Natixis Distribution in providing personal services to investors in Class A shares and/or the maintenance of shareholder accounts.

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

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

For the six months ended March 31, 2020, the service and distribution fees for each Fund were as follows:


	Service Fees				Distribution Fees
Fund	Class A		Class C		Class C
Intermediate Duration Bond Fund	$	26,857	$	609	$	1,825
Limited Term Government and Agency Fund		382,006		26,358		79,074

For the six months ended March 31, 2020, Natixis Distribution refunded Limited Term Government and Agency Fund $1,420 of prior year Class A 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, L.P. (“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. Pursuant to an agreement among Natixis Funds Trusts, Loomis Sayles Funds Trusts, Natixis ETF Trust 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 Trust, 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 Trust of $10 million, which is reevaluated on an annual basis.

For the six months ended March 31, 2020, the administrative fees for each Fund were as follows:


Fund	Administrative Fees
Intermediate Duration Bond Fund	$	53,906
Limited Term Government and Agency Fund		173,128

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 six months ended March 31, 2020, the sub-transfer agent fees (which are reflected in transfer agent fees and expenses in the Statements of Operations) for each Fund were as follows:


Fund	Sub-Transfer Agent Fees
Intermediate Duration Bond Fund	$	86,663
Limited Term Government and Agency Fund		203,153


Fund	Reimbursements of Sub-Transfer Agent Fees
Intermediate Duration Bond Fund	$	1,987
Limited Term Government and Agency Fund		13,063

Sub-transfer agent fees attributable to Class A, Class C and Class Y 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.

f. Trustees Fees and Expenses. The Trusts do not pay any compensation directly to their officers or Trustees who are directors, officers or employees of Natixis Advisors, Natixis Distribution, Natixis 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 $199,000. 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 Trust 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.

Transfer agent fees and expenses attributable to Class A, Class C, and Class Y 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. Transfer agent fees and expenses attributable to Class N are allocated to Class N.

For the six months ended March 31, 2020, the Funds incurred the following class-specific transfer agent fees and expenses (including sub-transfer agent fees, where applicable):


	Transfer Agent Fees and Expenses
Fund	Class A		Class C		Class N		Class Y

9. Risk. Limited Term Government and Agency Fund’s investments in mortgage-related and asset-backed securities are subject to certain risks not associated with investments in other securities. Mortgage-related and asset-backed securities are subject to the risk that unexpected changes in interest rates will have a direct effect on expected maturity. A shortened maturity may result in the reinvestment of prepaid amounts in securities with lower yields than the original obligations. An extended maturity may result in a reduction of a security’s value.
