Notes to Financial Statements (Unaudited)

For the period ended February 28, 2023

( Amounts in thousands except percentages)

1. Organization.

Fidelity Short-Term Bond Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class M, Class C, Short-Term Bond, Class I and Class Z shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class C shares will automatically convert to Class A shares after a holding period of eight years from the initial date of purchase, with certain exceptions.

2. Investments in Fidelity Central Funds.

Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Schedule of Investments lists any Fidelity Central Funds held as an investment as of period end, but does not include the underlying holdings of each Fidelity Central Fund. An investing fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

Based on its investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the investing fund. These strategies are consistent with the investment objectives of the investing fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the investing fund.

Fidelity Central Fund	Investment Manager	Investment Objective	Investment Practices	Expense Ratio A
Fidelity Money Market Central Funds	Fidelity Management & Research Company LLC (FMR)	Each fund seeks to obtain a high level of current income consistent with the preservation of capital and liquidity.	Short-term Investments	Less than .005%

A Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund's most recent annual or semi-annual shareholder report.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds which contain the significant accounting policies (including investment valuation policies) of those funds, and are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.

3. Significant Accounting Policies.

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies . The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds (ETFs) but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of the Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has designated the Fund's investment adviser as the valuation designee responsible for the fair valuation function and performing fair value determinations as needed. The investment adviser has established a Fair Value Committee (the Committee) to carry out the day-to-day fair valuation responsibilities and has adopted policies and procedures to govern the fair valuation process and the activities of the Committee. In accordance with these fair valuation policies and procedures, which have been approved by the Board, the Fund attempts to obtain prices from one or more third party pricing services or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with the policies and procedures. Factors used in determining fair value vary by investment type and may include market or investment specific events, transaction data, estimated cash flows, and market observations of comparable investments. The frequency that the fair valuation procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee manages the Fund's fair valuation practices and maintains the fair valuation policies and procedures. The Fund's investment adviser reports to the Board information regarding the fair valuation process and related material matters.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing services or from brokers who make markets in such securities. Corporate bonds and U.S. government and government agency obligations are valued by pricing services who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Asset backed securities, collateralized mortgage obligations, commercial mortgage securities and U.S. government agency mortgage securities are valued by pricing services who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of February 28, 2023 is included at the end of the Fund's Schedule of Investments.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of a fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of a fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred, as applicable. Certain expense reductions may also differ by class, if applicable. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan) for certain Funds, certain independent Trustees have elected to defer receipt of a portion of their annual compensation. Deferred amounts are invested in affiliated mutual funds, are marked-to-market and remain in a fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees presented below are included in the accompanying Statement of Assets and Liabilities in other receivables and other payables and accrued expenses, as applicable.

Fidelity Short-Term Bond Fund

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to futures contracts, market discount, capital loss carryforwards and losses deferred due to wash sales.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:

Gross unrealized appreciation	$1,583
Gross unrealized depreciation	(83,685)
Net unrealized appreciation (depreciation)	$(82,102)
Tax cost	$2,746,168

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of prior fiscal period end and is subject to adjustment.

Short-term	$(12,394)
Long-term	(10,129)
Total capital loss carryforward	$(22,523)

Delayed Delivery Transactions and When-Issued Securities. During the period, certain Funds transacted in securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Securities purchased on a delayed delivery or when-issued basis are identified as such in the Schedule of Investments. Compensation for interest forgone in the purchase of a delayed delivery or when-issued debt security may be received. With respect to purchase commitments, each applicable Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Payables and receivables associated with the purchases and sales of delayed delivery securities having the same coupon, settlement date and broker are offset. Delayed delivery or when-issued securities that have been purchased from and sold to different brokers are reflected as both payables and receivables in the Statement of Assets and Liabilities under the caption "Delayed delivery", as applicable. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities (including Private Placements). Funds may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities held at period end is included at the end of the Schedule of Investments, if applicable.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objectives allow for various types of derivative instruments, including futures contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

Derivatives were used to increase returns and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the objectives may not be achieved.

Derivatives were used to increase or decrease exposure to the following risk(s):


Interest Rate Risk	Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. Futures contracts were used to manage exposure to the bond market and fluctuations in interest rates.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent daily payments are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Statement of Operations.

Any open futures contracts at period end are presented in the Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end, and is representative of volume of activity during the period unless an average notional amount is presented. Any securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Any cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, U.S. government securities and in-kind transactions, as applicable, are noted in the table below.

	Purchases ($)	Sales ($)
Fidelity Short-Term Bond Fund	185,700	207,072

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and an annualized group fee rate that averaged .10% during the period. The group fee rate is based upon the monthly average net assets of a group of registered investment companies with which the investment adviser has management contracts. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the reporting period, the total annualized management fee rate was .30% of the Fund's average net assets.

During March 2023, the Board approved changes to the management fee effective April 1, 2023. The Fund will pay a monthly management fee that is based on an annual rate of .20% of the Fund's average net assets. Under the management contract, the investment adviser will pay all other fund-level expenses, except the compensation of the independent Trustees and certain other expenses such as proxy and shareholder meeting expenses.

Distribution and Service Plan Fees. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Company LLC (FDC), an affiliate of the investment adviser, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates, total fees and amounts retained by FDC were as follows:

	Distribution Fee	Service Fee	Total Fees	Retained by FDC
Class A	-%	.15%	$166	$19
Class M	-%	.15%	41	- A
Class C	.75%	.25%	140	24
			$347	$43

A Amount represents less than five hundred dollars.

Sales Load. FDC may receive a front-end sales charge of up to 1.50% for selling Class A and Class M shares, some of which is paid to financial intermediaries for selling shares of the Fund. Depending on the holding period, FDC may receive a contingent deferred sales charges levied on Class A, Class M and Class C redemptions. The deferred sales charges are 1.00% for Class C shares, .75% or .50% for certain purchases of Class A shares and .25% for certain purchases of Class M shares.

For the period, sales charge amounts retained by FDC were as follows:

	Retained by FDC
Class A	$18
Class M	2
Class C A	- B
	$20

A When Class C shares are initially sold, FDC pays commissions from its own resources to financial intermediaries through which the sales are made.

B Amount represents less than five hundred dollars.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of each respective class of the Fund, with the exception of Short-Term Bond and Class Z. FIIOC receives an asset-based fee of Short-Term Bond's and Class Z's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, transfer agent fees for each class were as follows:

	Amount	% of Class-Level Average Net Assets A
Class A	$162	.15
Class M	44	.16
Class C	23	.16
Short-Term Bond	1,015	.10
Class I	188	.15
Class Z	39	.05
	$1,471

A Annualized

Fund Wide Operations Fee. Pursuant to the Fund Wide Operations and Expense Agreement (FWOE), the investment adviser has agreed to provide for fund-level expenses (which may not include transfer agent, the compensation of the independent Trustees, interest, taxes or extraordinary expenses, as applicable) in return for a FWOE fee equal to .35% of fund-level average net assets less the total amount of the management fee. The FWOE paid by a fund is reduced by an amount equal to the fees and expenses paid to the independent Trustees. For the period, the FWOE fees were equivalent to the following annualized rate expressed as a percentage of average net assets:

During March 2023, the Board approved the termination of the FWOE effective April 1, 2023.

Interfund Trades. Funds may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. Any interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note. During the period, there were no interfund trades.

7. Committed Line of Credit.

Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The commitment fees on the pro-rata portion of the line of credit are borne by the investment adviser. During the period, there were no borrowings on this line of credit.

8. Security Lending.

Funds lend portfolio securities from time to time in order to earn additional income. Lending agents are used, including National Financial Services (NFS), an affiliate of the investment adviser. Pursuant to a securities lending agreement, NFS will receive a fee, which is capped at 9.9% of a fund's daily lending revenue, for its services as lending agent. A fund may lend securities to certain qualified borrowers, including NFS. On the settlement date of the loan, a fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of a fund and any additional required collateral is delivered to a fund on the next business day. A fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund may apply collateral received from the borrower against the obligation. A fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. Any loaned securities are identified as such in the Schedule of Investments, and the value of loaned securities and cash collateral at period end, as applicable, are presented in the Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Affiliated security lending activity, if any, was as follows:

	Total Security Lending Fees Paid to NFS	Security Lending Income From Securities Loaned to NFS	Value of Securities Loaned to NFS at Period End

9. Expense Reductions.

The investment adviser contractually agreed to reimburse expenses of each class to the extent annual operating expenses exceeded certain levels of class-level average net assets as noted in the table below. Some expenses, for example the compensation of the independent Trustees and certain other expenses such as interest expense, are excluded from this reimbursement.

The following classes were in reimbursement during the period:

	Expense Limitations	Reimbursement
Class Z	.36%	$33

Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. During the period, custodian credits reduced the Fund's expenses by $1.

Effective April 1, 2023, the investment adviser contractually agreed to reimburse expenses to the extent annual operating expenses exceed certain levels of class-level average net assets as noted in the table below. This reimbursement will remain in place through December 31, 2024. Some expenses, for example the compensation of the independent Trustees, and certain miscellaneous expenses such proxy and shareholder meeting expenses, are excluded from this reimbursement.

12. Other.

A fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.

13. Credit Risk.

The Fund invests a significant portion of its assets in structured securities of issuers backed by commercial and residential mortgage loans, credit card receivables and automotive loans. The value and related income of these securities is sensitive to changes in economic conditions, including delinquencies and/or defaults.

14. Risk and Uncertainties.

Many factors affect a fund's performance. Developments that disrupt global economies and financial markets, such as pandemics, epidemics, outbreaks of infectious diseases, war, terrorism, and environmental disasters, may significantly affect a fund's investment performance. The effects of these developments to a fund will be impacted by the types of securities in which a fund invests, the financial condition, industry, economic sector, and geographic location of an issuer, and a fund's level of investment in the securities of that issuer. Significant concentrations in security types, issuers, industries, sectors, and geographic locations may magnify the factors that affect a fund's performance.

As a shareholder, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments or redemption proceeds, as applicable and (2) ongoing costs, which generally include management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in a fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2022 to February 28, 2023).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class/Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If any fund is a shareholder of any underlying mutual funds or exchange-traded funds (ETFs) (the Underlying Funds), such fund indirectly bears its proportional share of the expenses of the Underlying Funds in addition to the direct expenses incurred presented in the table. These fees and expenses are not included in the annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. If any fund is a shareholder of any Underlying Funds, such fund indirectly bears its proportional share of the expenses of the Underlying Funds in addition to the direct expenses as presented in the table. These fees and expenses are not included in the annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Short-Term Bond Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established four standing committees (Committees) - Operations, Audit, Fair Valuation, and Governance and Nominating - each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Operations Committee, of which all the Independent Trustees are members, meets regularly throughout the year and requests, receives and considers, among other matters, information related to the annual consideration of the renewal of the fund's Advisory Contracts before making its recommendation to the Board. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet from time to time with trustees of other Fidelity funds through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.

At its September 2022 meeting, the Board unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness relative to peer funds of the fund's management fee and the total expense ratio of a representative class (the retail class); (iii) the total costs of the services provided by and the profits realized by Fidelity from its relationships with the fund; and (iv) the extent to which, if any, economies of scale exist and are realized as the fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts was fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, was aware that shareholders of the fund have a broad range of investment choices available to them, including a wide choice among funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, which is part of the Fidelity family of funds.

Nature, Extent, and Quality of Services Provided . The Board considered Fidelity's staffing as it relates to the fund, including the backgrounds of investment personnel of Fidelity, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund. Additionally, the Board considered the portfolio managers' investments, if any, in the funds that they manage. The Board also considered the steps Fidelity had taken to ensure the continued provision of high quality services to the Fidelity funds throughout the COVID-19 pandemic, including the expansion of staff in client facing positions to maintain service levels in periods of high volumes and volatility.

Resources Dedicated to Investment Management and Support Services. The Board reviewed the general qualifications and capabilities of Fidelity's investment staff, including its size, education, experience, and resources, as well as Fidelity's approach to recruiting, training, managing, and compensating investment personnel. The Board noted the resources devoted to Fidelity's global investment organization, and that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. Further, the Board considered that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered Fidelity's trading, risk management, compliance, cybersecurity and technology and operations capabilities and resources, which are integral parts of the investment management process.

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures.

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value and convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information over the Internet and through telephone representatives, investor education materials and asset allocation tools. The Board also considered that it reviews customer service metrics such as telephone response times, continuity of services on the website and metrics addressing services at Fidelity Investor Centers.

Investment in a Large Fund Family. The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations to the Board that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including: (i) continuing to dedicate additional resources to Fidelity's investment research process, which includes meetings with management of issuers of securities in which the funds invest; (ii) continuing efforts to enhance Fidelity's global research capabilities; (iii) launching new funds, ETFs, and share classes with innovative structures, strategies and pricing and making other enhancements to meet investor needs; (iv) broadening eligibility requirements for certain funds and share classes; (v) reducing management fees and total expenses for certain funds and classes; (vi) lowering expenses for certain existing funds and classes by implementing or lowering expense caps; (vii) rationalizing product lines and gaining increased efficiencies from fund mergers and liquidations; (viii) continuing to develop, acquire and implement systems and technology to improve services to the funds and shareholders, strengthen information security, and increase efficiency; and (ix) continuing to implement enhancements to further strengthen Fidelity's product line to increase investors' probability of success in achieving their investment goals, including their retirement income goals.

The Board took into account discussions that occur at Board meetings throughout the year with representatives of the Investment Advisers about fund investment performance. In this regard the Board noted that as part of regularly scheduled fund reviews and other reports to the Board on fund performance, the Board considers annualized return information for the fund for different time periods, measured against an appropriate securities market index (benchmark index) and an appropriate peer group of funds with similar objectives (peer group). The Board also receives and considers information about performance attribution. In its evaluation of fund investment performance at meetings throughout the year, the Board gave particular attention to information indicating underperformance of certain Fidelity funds for specific time periods and discussed with the Investment Advisers the reasons for such underperformance.

In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. In general, the Independent Trustees believe that fund performance should be evaluated based on gross performance (before fees and expenses but after transaction costs) compared to appropriate benchmark indices, over appropriate time periods that may include full market cycles, and on net performance (after fees and expenses) compared to appropriate peer groups, as applicable, over the same periods, taking into account relevant factors including the following: general market conditions; expectations for interest rate levels and credit conditions; issuer-specific information including credit quality; the potential for incremental return versus the fund's benchmark index weighed against the risks involved in obtaining that incremental return, including the risk of diminished or negative total returns; and fund cash flows and other factors. The Independent Trustees generally give greater weight to fund performance over longer time periods than over shorter time periods. Depending on the circumstances, the Independent Trustees may be satisfied with a fund's performance notwithstanding that it lags its benchmark index or peer group for certain periods.

The Independent Trustees recognize that shareholders evaluate performance on a net basis over their own holding periods, for which one-, three-, and five-year periods are often used as a proxy. For this reason, the performance information reviewed by the Board also included net cumulative calendar year total return information for the representative class (the retail class) and an appropriate benchmark index and peer group for the most recent one-, three-, and five-year periods. The Independent Trustees recognize that shareholders who are not investing through a tax-advantaged retirement account also consider tax consequences in evaluating performance.

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should continue to benefit the shareholders of the fund.

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to selected groups of competitive funds and classes (referred to as "mapped groups" below) for the purpose of facilitating the Trustees' competitive analysis of management fees and total expenses. Fidelity creates "mapped groups" by combining similar investment objective categories (as classified by Lipper) that have comparable investment mandates. Combining funds with similar investment objective categories aids the Board's comparison of management fees and total expense ratios by broadening the competitive group used for such comparison.

Management Fee. The Board considered two proprietary management fee comparisons for the 12-month periods shown in basis points (BP) in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group" and is broader than the Lipper peer group used by the Board for performance comparisons. The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps relative to the total universe of funds with comparable investment mandates, regardless of whether their management fee structures also are comparable. Funds with comparable investment mandates offer exposure to similar types of securities. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than the fund. The fund's actual TMG %s and the number of funds in the Total Mapped Group are in the chart below. The "Asset-Sized Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee rate ranked, is also included in the chart and was considered by the Board.

The Board noted that the fund's management fee rate ranked below the median of its Total Mapped Group and below the median of its ASPG for 2021.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio. In its review of the total expense ratio of the representative class (the retail class) of the fund, the Board considered the fund's management fee rate as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, fund-paid 12b-1 fees, and custodial, legal, and audit fees. The Board also noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund. The fund's representative classis compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure. The Board also considered a total expense ASPG comparison, which focuses on the total expenses of the representative class relative to a subset of non-Fidelity funds within the similar sales load structure group that are similar in size and management fee structure. The total expense ASPG is limited to 15 larger and 15 smaller classes of different funds, where possible. The total expense ASPG comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in expenses relating to these items.

The Board noted that the total net expense ratio of the retail class ranked below the similar sales load structure group competitive median for 2021 and above the ASPG competitive median for 2021. The Board further noted that total expense ratio of the retail class was 10 BP above its ASPG median but that, when compared to funds with investment strategies of investing primarily in short term investment grade debt within the ASPG, and excluding funds in a fund complex with an unique at-cost service model from the ASPG, the retail class ranked below median. The Board noted that the fund offers multiple classes, each of which has a different 12b-1 fee structure than the others, and that the multiple structures are intended to offer a range of pricing options for the intermediary market. The Board also noted that the total expense ratios of the classes vary primarily by the level of their 12b-1 fees, although differences in transfer agent fees may also cause expenses to vary from class to class.

Fees Charged to Other Fidelity Clients. The Board also considered Fidelity fee structures and other information with respect to clients of Fidelity, such as other funds advised or subadvised by Fidelity, pension plan clients, and other institutional clients with similar mandates. The Board noted that a joint ad hoc committee created by it and the boards of other Fidelity funds periodically reviews and compares Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds and also noted the most recent findings of the committee. The Board noted that the committee's review included a consideration of the differences in services provided, fees charged, and costs incurred, as well as competition in the markets serving the different categories of clients.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the total expense ratio of each class of the fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, Fidelity presents to the Board information about the profitability of its relationships with the fund. Fidelity calculates profitability information for each fund, as well as aggregate profitability information for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies and the full Board approves such changes.

The Board also reviewed Fidelity's non-fund businesses and potential indirect benefits such businesses may have received as a result of their association with Fidelity's mutual fund business (i.e., fall-out benefits) as well as cases where Fidelity's affiliates may benefit from the funds' business. The Board considered areas where potential indirect benefits to the Fidelity funds from their relationships with Fidelity may exist. The Board's consideration of these matters was informed by the findings of a joint ad hoc committee created by it and the boards of other Fidelity funds to evaluate potential fall-out benefits.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) Fidelity's fund profitability methodology, profitability trends for certain funds, the allocation of various costs to different funds, and the impact of certain factors on fund profitability results; (ii) portfolio manager changes that have occurred during the past year and the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (iii) the extent to which current market conditions have affected retention and recruitment of personnel; (iv) the arrangements with and compensation paid to certain fund sub-advisers on behalf of the Fidelity funds and the treatment of such compensation within Fidelity's fund profitability methodology; (v) the terms of the funds' various management fee structures, including the basic group fee and the terms of Fidelity's voluntary expense limitation arrangements; (vi) Fidelity's transfer agent, pricing and bookkeeping fees, expense and service structures for different funds and classes relative to competitive trends; (vii) the impact on fund profitability of recent industry trends, such as the growth in passively managed funds and the changes in flows for different types of funds; (viii) the types of management fee and total expense comparisons provided, and the challenges and limitations associated with such information; and (ix) explanations regarding the relative total expense ratios and management fees of certain funds and classes, total expense and management fee competitive trends, and methodologies for total expense and management fee competitive comparisons. In addition, the Board considered its discussions with Fidelity regarding Fidelity's efforts to maintain the continuous investment and shareholder services necessary for the funds during the current pandemic and economic circumstances.

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board concluded that the advisory fee arrangements are fair and reasonable and that the fund's Advisory Contracts should be renewed.

The Securities and Exchange Commission adopted Rule 22e-4 under the Investment Company Act of 1940 (the Liquidity Rule) to promote effective liquidity risk management throughout the open-end investment company industry, thereby reducing the risk that funds will be unable to meet their redemption obligations and mitigating dilution of the interests of fund shareholders.

The Fund has adopted and implemented a liquidity risk management program (the Program) reasonably designed to assess and manage the Fund's liquidity risk and to comply with the requirements of the Liquidity Rule. The Fund's Board of Trustees (the Board) has designated the Fund's investment adviser as administrator of the Program. The Fidelity advisers have established a Liquidity Risk Management Committee (the LRM Committee) to manage the Program for each of the Fidelity Funds. The LRM Committee monitors the adequacy and effectiveness of implementation of the Program and on a periodic basis assesses each Fund's liquidity risk based on a variety of factors including (1) the Fund's investment strategy, (2) portfolio liquidity and cash flow projections during normal and reasonably foreseeable stressed conditions, (3) shareholder redemptions, (4) borrowings and other funding sources and (5) certain factors specific to ETFs including the effect of the Fund's prices and spreads, market participants, and basket compositions on the overall liquidity of the Fund's portfolio, as applicable.

In accordance with the Program, each of the Fund's portfolio investments is classified into one of four defined liquidity categories based on a determination of a reasonable expectation for how long it would take to convert the investment to cash (or sell or dispose of the investment) without significantly changing its market value.

Highly liquid investments - cash or convertible to cash within three business days or less
Moderately liquid investments - convertible to cash in three to seven calendar days
Less liquid investments - can be sold or disposed of, but not settled, within seven calendar days
Illiquid investments - cannot be sold or disposed of within seven calendar days

Liquidity classification determinations take into account a variety of factors including various market, trading and investment-specific considerations, as well as market depth, and generally utilize analysis from a third-party liquidity metrics service.

The Liquidity Rule places a 15% limit on a fund's illiquid investments and requires funds that do not primarily hold assets that are highly liquid investments to determine and maintain a minimum percentage of the fund's net assets to be invested in highly liquid investments (highly liquid investment minimum or HLIM). The Program includes provisions reasonably designed to comply with the 15% limit on illiquid investments and for determining, periodically reviewing and complying with the HLIM requirement as applicable.

At a recent meeting of the Fund's Board of Trustees, the LRM Committee provided a written report to the Board pertaining to the operation, adequacy, and effectiveness of the Program for the period December 1, 2021 through November 30, 2022. The report concluded that the Program is operating effectively and is reasonably designed to assess and manage the Fund's liquidity risk.

Notes to Financial Statements (Unaudited)

For the period ended February 28, 2023

A Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund's most recent annual or semi-annual shareholder report.

An unaudited holdings listing for the investing fund, which presents direct holdings as well as the pro-rata share of any securities and other investments held indirectly through its investment in underlying non-money market Fidelity Central Funds, is available at fidelity.com and/or institutional.fidelity.com, as applicable. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds which contain the significant accounting policies (including investment valuation policies) of those funds, and are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.

3. Significant Accounting Policies.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

The U.S. dollar value of forward foreign currency contracts is determined using currency exchange rates supplied by a pricing service and are categorized as Level 2 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Foreign Currency. Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received, and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Realized gains and losses on foreign currency transactions arise from the disposition of foreign currency, realized changes in the value of foreign currency between the trade and settlement dates on security transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on transaction date and the U.S. dollar equivalent of the amounts actually received or paid. Unrealized gains and losses on assets and liabilities in foreign currencies arise from changes in the value of foreign currency, and from assets and liabilities denominated in foreign currencies, other than investments, which are held at period end.

Book-tax differences are primarily due to the short-term gain distributions from the underlying mutual funds or exchange-traded funds (ETFs), foreign currency transactions, market discount, capital loss carryforwards, and losses deferred due to wash sales and currency forward transactions.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:

Gross unrealized appreciation	$58,874
Gross unrealized depreciation	(2,431,584)
Net unrealized appreciation (depreciation)	$(2,372,710)
Tax cost	$36,458,135

Short-term	$(686,778)

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objectives allow for various types of derivative instruments, including forward foreign currency contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

Derivatives were used to increase returns, to facilitate transactions in foreign-denominated securities and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the objectives may not be achieved.

Derivatives were used to increase or decrease exposure to the following risk(s):


Foreign Exchange Risk	Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates.

Funds are also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that a fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to a fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as forward foreign currency contracts, a fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives a fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. To mitigate counterparty credit risk on bi-lateral OTC derivatives, a fund receives collateral in the form of cash or securities once net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the custodian bank in accordance with the collateral agreements entered into between a fund, the counterparty and the custodian bank. A fund could experience delays and costs in gaining access to the collateral even though it is held by the custodian bank. The maximum risk of loss to a fund from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to a fund. A fund may be required to pledge collateral for the benefit of the counterparties on bi-lateral OTC derivatives in an amount not less than each counterparty's unrealized appreciation on outstanding derivative contracts, subject to certain minimum transfer provisions, and any such pledged collateral is identified in the Schedule of Investments.

Forward Foreign Currency Contracts. Forward foreign currency contracts represent obligations to purchase or sell foreign currency on a specified future date at a price fixed at the time the contracts are entered into. Forward foreign currency contracts were used to facilitate transactions in foreign-denominated securities and to manage exposure to certain foreign currencies.

Forward foreign currency contracts are valued daily and fluctuations in exchange rates on open contracts are recorded as unrealized appreciation or (depreciation) and reflected in total accumulated earnings (loss) in the Statement of Assets and Liabilities. When the contract is closed, a gain or loss is realized equal to the difference between the closing value and the value at the time it was opened. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on forward foreign currency contracts during the period is presented in the Statement of Operations.

Any open forward foreign currency contracts at period end are presented in the Schedule of Investments under the caption "Forward Foreign Currency Contracts." The contract amount and unrealized appreciation (depreciation) reflects each contract's exposure to the underlying currency at period end, and is representative of volume of activity during the period unless an average contract value is presented.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and in-kind transactions, as applicable, are noted in the table below.

	Purchases ($)	Sales ($)
Fidelity Tactical Bond Fund	2,553,395	3,204,830

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .45% of the Fund's average net assets and an annualized group fee rate that averaged .10% during the period. In September 2022 the Board approved a change in the individual fund fee rate from .50% to .45% effective October 1, 2022. The group fee rate is based upon the monthly average net assets of a group of registered investment companies with which the investment adviser has management contracts. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the reporting period, the total annualized management fee rate was .56% of the Fund's average net assets.

	Distribution Fee	Service Fee	Total Fees	Retained by FDC
Class A	-%	.25%	$3,616	$2,856
Class M	-%	.25%	3,114	2,848
Class C	.75%	.25%	11,635	11,330
			$18,365	$17,034

Sales Load. FDC may receive a front-end sales charge of up to 4.00% for selling Class A shares and Class M shares, some of which is paid to financial intermediaries for selling shares of the Fund. Depending on the holding period, FDC may receive contingent deferred sales charges levied on Class A, Class M and Class C redemptions. The deferred sales charges are 1.00% for Class C shares, .75% for certain purchases of Class A shares and .25% for certain purchases of Class M shares.

For the period, sales charge amounts retained by FDC were as follows:

	Retained by FDC
Class A	$102

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund, except for Class Z. FIIOC receives an asset-based fee of Class Z's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

For the period, transfer agent fees for each class were as follows:

	Amount	% of Class-Level Average Net Assets A
Class A	$1,969	.14

Fidelity Tactical Bond Fund	.04

7. Committed Line of Credit.

Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The participating funds have agreed to pay commitment fees on their pro-rata portion of the line of credit, which are reflected in Miscellaneous expenses on the Statement of Operations, and are listed below. During the period, there were no borrowings on this line of credit.

This reimbursement will remain in place through December 31, 2024. Some expenses, for example the compensation of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses, are excluded from this reimbursement.

The following classes were in reimbursement during the period:

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Tactical Bond Fund

At its September 2022 meeting the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve an amended and restated management contract (the Amended Contract) for the fund to decrease the management fees paid to Fidelity Management & Research Company LLC (FMR), the fund's investment adviser, by 5 basis points, effective October 1, 2022. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, considered a broad range of information.

Nature, Extent, and Quality of Services Provided. The Board previously received and considered materials relating to the nature, extent and quality of services to be provided by FMR to the fund, including the resources dedicated to investment management and support services, shareholder and administrative services, and the benefits to shareholders of investment in a large fund family in connection with the approval of the fund's current management contract (Current Management Contract). At its November 2021 meeting, the Board concluded that the nature, extent and quality of the services to be provided to the fund under the Current Management Contract should benefit the fund's shareholders. In connection with its approval of the Amended Contract at its September 2022 meeting, the Board noted that such approval would not change the fund's portfolio managers, the investment processes, the level or nature of services provided, the resources and personnel allocated or trading and compliance operations. The Board concluded that the nature, extent, and quality of services to be provided to the fund under the Amended Contract will continue to benefit the fund's shareholders.

Competitiveness of Management Fee and Total Expense Ratio. In reviewing the Amended Contract, the Board considered the fund's proposed management fee rate, which is 5 basis points lower than the current management fee rate, and the projected total net expense ratio of each class of the fund. The Board noted that the fund's proposed management fee rate is lower than the median fee rate of funds with similar Lipper investment objective categories and comparable investment mandates, regardless of whether their management fee structures are comparable. The Board also considered that the projected total net expense ratio of each of Class A, Class M, Class C, Class Z, and the retail class of the fund is below the median of those funds and classes used by the Board for management fee comparisons that have a similar sales load structure, and the projected total net expense ratio of Class I is at the median.

The Board also noted that FMR has contractually agreed to reimburse each class of the fund to the extent that total operating expenses, with certain exceptions, as a percentage of their respective average net assets, exceed a certain limit through December 31, 2024.

Based on its review, the Board concluded that the management fee and the projected total net expense ratio of each class of the fund continue to be fair and reasonable in light of the services that each fund receives and the other factors considered.

Costs of the Services and Profitability. Because the Board was approving an arrangement under which the management fees were being reduced, the Board did not consider FMR's costs of services, revenues, or profitability to be significant factors in its decision to approve the Amended Contract.

Economies of Scale. In connection with the approval of the fund's Amended Contract, the Board did not consider economies of scale because the proposed fee arrangement lowers the fund's management fee and FMR will continue to contractually limit expenses. The Board will review economies of scale in connection with its consideration of future renewals of the Amended Contract.

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board ultimately concluded that the advisory fee structure is fair and reasonable, and that the fund's Amended Contract should be approved.

Notes to Financial Statements (Unaudited)

For the period ended February 28, 2023

1. Organization.

Fidelity Sustainable Low Duration Bond Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class M, Class C, Sustainable Low Duration Bond, Class I and Class Z shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class C shares will automatically convert to Class A shares after a holding period of eight years from the initial date of purchase, with certain exceptions.

2. Investments in Fidelity Central Funds.

Fidelity Central Fund	Investment Manager	Investment Objective	Investment Practices	Expense Ratio A
Fidelity Money Market Central Funds	Fidelity Management & Research Company LLC (FMR)	Each fund seeks to obtain a high level of current income consistent with the preservation of capital and liquidity.	Short-term Investments	Less than .005%

A Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund's most recent annual or semi-annual shareholder report.

3. Significant Accounting Policies.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing services or from brokers who make markets in such securities. Corporate bonds, bank notes and U.S. government and government agency obligations are valued by pricing services who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Asset backed securities are valued by pricing services who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Book-tax differences are primarily due to market discount and losses deferred due to wash sales.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:

Gross unrealized appreciation	$99,332
Gross unrealized depreciation	(17,727)
Net unrealized appreciation (depreciation)	$81,605
Tax cost	$23,074,011

Notes to Financial Statements (Unaudited)

For the period ended February 28, 2023

1. Organization.

Fidelity Sustainable Core Plus Bond Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class M, Class C, Fidelity Sustainable Core Plus Bond Fund, Class I and Class Z shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class C shares will automatically convert to Class A shares after a holding period of eight years from the initial date of purchase, with certain exceptions.

2. Investments in Fidelity Central Funds.

Fidelity Central Fund	Investment Manager	Investment Objective	Investment Practices	Expense Ratio A
Fidelity Money Market Central Funds	Fidelity Management & Research Company LLC (FMR)	Each fund seeks to obtain a high level of current income consistent with the preservation of capital and liquidity.	Short-term Investments	Less than .005%

A Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund's most recent annual or semi-annual shareholder report.

3. Significant Accounting Policies.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing services or from brokers who make markets in such securities. Corporate bonds, bank loan obligations, foreign government and government agency obligations, preferred securities and U.S. government and government agency obligations are valued by pricing services who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Asset backed securities, commercial mortgage securities and U.S. government agency mortgage securities are valued by pricing services who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. For foreign debt securities, when significant market or security specific events arise, valuations may be determined in good faith in accordance with procedures adopted by the Board. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, ETFs and certain indexes as well as quoted prices for similar securities may be used and would be categorized as Level 2 in the hierarchy. For equity securities, including restricted securities, where observable inputs are limited, assumptions about market activity and risk are used and these securities may be categorized as Level 3 in the hierarchy.

Foreign Currency. Certain Funds may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received, and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

Book-tax differences are primarily due to futures contracts, foreign currency transactions, market discount, capital loss carryforwards and losses deferred due to wash sales.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:

Gross unrealized appreciation	$85,541
Gross unrealized depreciation	(1,907,638)
Net unrealized appreciation (depreciation)	$(1,822,097)
Tax cost	$36,032,037

Short-term	$(75,548)
Long-term	(1,343)
Total capital loss carryforward	$(76,891)

To-Be-Announced (TBA) Securities and Mortgage Dollar Rolls. TBA securities involve buying or selling mortgage-backed securities (MBS) on a forward commitment basis. A TBA transaction typically does not designate the actual security to be delivered and only includes an approximate principal amount; however delivered securities must meet specified terms defined by industry guidelines, including issuer, rate and current principal amount outstanding on underlying mortgage pools. Funds may enter into a TBA transaction with the intent to take possession of or deliver the underlying MBS, or a fund may elect to extend the settlement by entering into either a mortgage or reverse mortgage dollar roll. Mortgage dollar rolls are transactions where a fund sells TBA securities and simultaneously agrees to repurchase MBS on a later date at a lower price and with the same counterparty. Reverse mortgage dollar rolls involve the purchase and simultaneous agreement to sell TBA securities on a later date at a lower price. Transactions in mortgage dollar rolls and reverse mortgage dollar rolls are accounted for as purchases and sales and may result in an increase to a fund's portfolio turnover rate.

Purchases and sales of TBA securities involve risks similar to those discussed above for delayed delivery and when-issued securities. Also, if the counterparty in a mortgage dollar roll or a reverse mortgage dollar roll transaction files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited. Additionally, when a fund sells TBA securities without already owning or having the right to obtain the deliverable securities (an uncovered forward commitment to sell), it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold them. A fund may be unable to purchase the deliverable securities if the corresponding market is illiquid.

TBA securities subject to a forward commitment to sell at period end are included at the end of the Schedule of Investments under the caption "TBA Sale Commitments." The proceeds and value of these commitments are reflected in the Statement of Assets and Liabilities as "Receivable for TBA sale commitments" and "TBA sale commitments, at value," respectively.

Loans and Other Direct Debt Instruments. Direct debt instruments are interests in amounts owed to lenders by corporate or other borrowers. These instruments may be in the form of loans, trade claims or other receivables and may include standby financing commitments such as revolving credit facilities that obligate a fund to supply additional cash to the borrower on demand. Loans may be acquired through assignment, participation, or may be made directly to a borrower. Such instruments are presented in the Bank Loan Obligations section in the Schedule of Investments. Certain funds may also invest in unfunded loan commitments, which are contractual obligations for future funding. Information regarding unfunded commitments is included at the end of the Schedule of Investments, if applicable.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objectives allow for various types of derivative instruments, including futures contracts and forward foreign currency contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

Derivatives were used to increase or decrease exposure to the following risk(s):


Foreign Exchange Risk	Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates.
Interest Rate Risk	Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates.

Net Realized Gain (Loss) and Change in Net Unrealized Appreciation (Depreciation) on Derivatives. The table below, which reflects the impacts of derivatives on the financial performance, summarizes the net realized gain (loss) and change in net unrealized appreciation (depreciation) for derivatives during the period as presented in the Statement of Operations.

Primary Risk Exposure / Derivative Type	Net Realized Gain (Loss)	Change in Net Unrealized Appreciation (Depreciation)
Fidelity Sustainable Core Plus Bond Fund
Foreign Exchange Risk
Forward Foreign Currency Contracts	$(18,434)	$(12,154)
Total Foreign Exchange Risk	(18,434)	(12,154)
Interest Rate Risk
Futures Contracts	$(25,678)	$4,997
Total Interest Rate Risk	(25,678)	4,997
Totals	$(44,112)	$(7,157)

If there are any open positions at period end, a summary of the value of derivatives by primary risk exposure is included at the end of the Schedule of Investments.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, U.S. government securities and in-kind transactions, as applicable, are noted in the table below.

	Purchases ($)	Sales ($)
Fidelity Sustainable Core Plus Bond Fund	31,130,833	30,793,734

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee that is based on an annual rate of .35% of the Fund's average net assets. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain other expenses such as proxy and shareholder meeting expenses.

	Distribution Fee	Service Fee	Total Fees	Retained by FDC

	Retained by FDC
Class A	$28

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund, except for Class Z. FIIOC receives an asset-based fee of Class Z's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

For the period, transfer agent fees for each class were as follows:

	Amount	% of Class-Level Average Net Assets A

7. Expense Reductions.

The investment adviser contractually agreed to reimburse expenses of each class to the extent annual operating expenses exceeded certain levels of class-level average net assets as noted in the table below.

Notes to Financial Statements (Unaudited)

For the period ended February 28, 2023

1. Organization.

Fidelity Series Government Money Market Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. Shares are offered only to certain other Fidelity funds, Fidelity managed 529 plans, and Fidelity managed collective investment trusts.

2. Significant Accounting Policies.

Investment Valuation. The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

As permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates fair value. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity. Securities held by a money market fund are generally high quality and liquid; however, they are reflected as Level 2 because the inputs used to determine fair value are not quoted prices in an active market.

Investment Transactions and Income. The net asset value per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time. Security transactions are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Book-tax differences are primarily due to losses deferred due to wash sales.

As of period end, the cost and unrealized appreciation (depreciation) in securities for federal income tax purposes were as follows:

Gross unrealized appreciation	$-
Gross unrealized depreciation	-
Net unrealized appreciation (depreciation)	$-
Tax cost	$4,285,828,391

Short-term

$(3,856)

Repurchase Agreements. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, funds and other registered investment companies having management contracts with Fidelity Management and Research Company LLC, or its affiliates are permitted to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. Funds may also invest directly with institutions in repurchase agreements. Repurchase agreements may be collateralized by cash or government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The collateral balance is monitored on a daily basis to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

3. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund does not pay a management fee. Under the management contract, the investment adviser or an affiliate pays all ordinary operating expenses of the Fund, except custody fees, fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

4. Expense Reductions.

Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses by $2,919.

5. Other.

At the end of the period, mutual funds and accounts managed by the investment adviser or its affiliates were the owners of record of all of the outstanding shares of the Fund.

6. Risk and Uncertainties.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2022 to February 28, 2023).

Actual		$ 1,000	$ 1,018.90	$- E
Hypothetical- B		$ 1,000	$ 1,024.79	$- E

A Annualized expense ratio reflects expenses net of applicable fee waivers.

B 5% return per year before expenses

D Amount represents less than .005%.

E Amount represents less than $.005.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Series Government Money Market Fund

At its September 2022 meeting, the Board unanimously determined to renew the fund's Advisory Contracts. In considering whether to renew the Advisory Contracts for the fund, the Board considered all factors it believed relevant and reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of the fund and its shareholders and the fact that no fee is payable under the management contract was fair and reasonable.

Nature, Extent, and Quality of Services Provided. The Board considered Fidelity's staffing as it relates to the fund, including the backgrounds of investment personnel of Fidelity, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund. The Board also considered the steps Fidelity had taken to ensure the continued provision of high quality services to the Fidelity funds throughout the COVID-19 pandemic, including the expansion of staff in client facing positions to maintain service levels in periods of high volumes and volatility.

Resources Dedicated to Investment Management and Support Services . The Board reviewed the general qualifications and capabilities of Fidelity's investment staff, including its size, education, experience, and resources, as well as Fidelity's approach to recruiting, training, managing, and compensating investment personnel. The Board noted the resources devoted to Fidelity's global investment organization, and that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. Further, the Board considered that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered Fidelity's trading, risk management, compliance, cybersecurity, and technology and operations capabilities and resources, which are integral parts of the investment management process.

Administrative Services . The Board considered (i) the nature, extent, quality, and cost of advisory and administrative services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures.

Investment Performance . The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. The Board reviewed the fund's absolute investment performance, as well as the fund's relative investment performance. In this regard, the Board noted that the fund is designed to offer an investment option for other investment companies, collective investment trusts, and 529 plans managed by Fidelity and ultimately to enhance the performance of those investment companies, collective investment trusts, and 529 plans.

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should continue to benefit the shareholders of the fund.

Competitiveness of Management Fee and Total Expense Ratio . The Board considered that the fund does not pay FMR a management fee for investment advisory services, but that FMR receives fees for providing services to funds, collective investment trusts, and 529 plans that invest in the fund. The Board also noted that FMR or an affiliate undertakes to pay all operating expenses of the fund, except transfer agent fees, 12b-1 fees, Independent Trustee fees and expenses, custodian fees and expenses, proxy and shareholder meeting expenses, interest, taxes, and extraordinary expenses (such as litigation expenses). The Board further noted that the fund pays its non-operating expenses, including brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable.

The Board further considered that FMR has contractually agreed to reimburse the fund to the extent that total operating expenses, with certain exceptions, as a percentage of its average net assets, exceed 0.003% through December 31, 2024.

Based on its review, the Board considered that the fund does not pay a management fee and concluded that the fund's total expense ratio was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability . The Board considered the level of Fidelity's profits in respect of all the Fidelity funds.

The Board concluded that the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund were not relevant to the renewal of the Advisory Contracts because the fund pays no advisory fees and FMR or an affiliate bears all expenses of the fund, with limited exceptions.

Economies of Scale. The Board concluded that because the fund pays no advisory fees and FMR or an affiliate bears all expenses of the fund with certain limited exceptions, the realization of economies of scale was not a material factor in the Board's decision to renew the fund's Advisory Contracts.

Additional Information Requested by the Board . In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) Fidelity's fund profitability methodology, profitability trends for certain funds, the allocation of various costs to different funds, and the impact of certain factors on fund profitability results; (ii) portfolio manager changes that have occurred during the past year and the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (iii) the extent to which current market conditions have affected retention and recruitment of personnel; (iv) the arrangements with and compensation paid to certain fund sub-advisers on behalf of the Fidelity funds and the treatment of such compensation within Fidelity's fund profitability methodology; (v) the terms of the funds' various management fee structures, including the basic group fee and the terms of Fidelity's voluntary expense limitation arrangements; (vi) Fidelity's transfer agent, pricing and bookkeeping fees, expense and service structures for different funds and classes relative to competitive trends; (vii) the impact on fund profitability of recent industry trends, such as the growth in passively managed funds and the changes in flows for different types of funds; (viii) the types of management fee and total expense comparisons provided, and the challenges and limitations associated with such information; and (ix) explanations regarding the relative total expense ratios and management fees of certain funds and classes, total expense and management fee competitive trends, and methodologies for total expense and management fee competitive comparisons. In addition, the Board considered its discussions with Fidelity regarding Fidelity's efforts to maintain the continuous investment and shareholder services necessary for the funds during the current pandemic and economic circumstances.
