Note to Shareholders:

Early in 2020, the outbreak and spread of a new coronavirus emerged as a public health emergency that had a major influence on financial markets, primarily based on its impact on the global economy and corporate earnings. The virus causes a respiratory disease known as COVID-19. On March 11, the World Health Organization declared the COVID-19 outbreak a pandemic, citing sustained risk of further global spread.

In the weeks following the end of this reporting period, as the crisis worsened, we witnessed an escalating human tragedy with wide-scale social and economic consequences from coronavirus-containment measures. The outbreak of COVID-19 prompted a number of measures to limit the spread, including travel and border restrictions, quarantines, and restrictions on large gatherings. In turn, these resulted in lower consumer activity, diminished demand for a wide range of products and services, disruption in manufacturing and supply chains, and – given the wide variability in outcomes regarding the outbreak – significant market uncertainty and volatility. Amid the turmoil, the U.S. government took unprecedented action – in concert with the U.S. Federal Reserve and central banks around the world – to help support consumers, businesses, and the broader economy, and to limit disruption to the financial system.

The situation continues to unfold, and the extent and duration of its impact on financial markets and the economy remain highly uncertain. Extreme events such as the coronavirus crisis are "exogenous shocks" that can have significant adverse effects on mutual funds and their investments. Although multiple asset classes may be affected by market disruption, the duration and impact may not be the same for all types of assets.

Fidelity is committed to helping you stay informed amid news about COVID-19 and during increased market volatility, and we’re taking extra steps to be responsive to customer needs. We encourage you to visit our websites, where we offer ongoing updates, commentary, and analysis on the markets and our funds.

Notes to Financial Statements
For the period ended February 29, 2020 (Unaudited)

1. Organization.

Fidelity Corporate Bond ETF, Fidelity Limited Term Bond ETF, Fidelity Low Duration Bond Factor ETF and Fidelity Total Bond ETF (the Funds) are exchange-traded funds of Fidelity Merrimack Street Trust (the Trust) and are 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.

2. Investments in Fidelity Central Funds.

The Funds 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 Funds' Schedules of Investments list each of the Fidelity Central Funds held as of period end, if any, as an investment of each Fund, but do not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, each Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by the investment adviser. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date ranged from less than .005% to 0.01%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC website or upon request.

3. Significant Accounting Policies.

Each 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 – Investments 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 following summarizes the significant accounting policies of the Funds:

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 delegated the day to day responsibility for the valuation of each Fund’s investments to the Fair Value Committee (the Committee) established by each Fund’s investment adviser. In accordance with valuation policies and procedures approved by the Board, each Fund attempts to obtain prices from one or more third party pricing vendors 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 procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees each Fund’s valuation policies and procedures and reports to the Board on the Committee’s activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing each Fund’s investments and ratifies the fair value determinations of the Committee.

Each 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 – 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 each 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 vendors or from brokers who make markets in such securities. Corporate bonds, bank loan obligations, foreign government and government agency obligations, municipal securities and U.S government and government agency obligations are valued by pricing vendors 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 and U.S. government agency mortgage securities are valued by pricing vendors 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 of 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 vendors. 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.

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.

Table of Contents

3. Significant Accounting Policies – continued

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 29, 2020, is included at the end of each Fund’s Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes and for processing shareholder transactions, the Funds' investment holdings and NAV include trades executed through the end of the last business day of the period and prior business day, respectively. The NAV per share for processing shareholder transactions is calculated as of the close of business of NYSE Arca for Fidelity Corporate Bond ETF, Fidelity Limited Term Bond ETF and Fidelity Total Bond ETF and of Cboe BZX Exchange, Inc. (CboeBZX) for Fidelity Low Duration Bond Factor ETF, normally 4:00 p.m. Eastern time. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Paid in Kind (PIK) income is recorded at the fair market value of the securities received. The principal amount on inflation-indexed securities is periodically adjusted to the rate of inflation and interest is accrued based on the principal amount. The adjustments to principal due to inflation are reflected as increases or decreases to Interest in the accompanying Statements of Operations. Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.

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. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, each 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. Each Fund files a U.S. federal tax return, in addition to state and local tax returns as required. Each 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. Realized gain or loss resulting from in-kind redemptions is not taxable to the Fund and is not distributed to shareholders of the Fund.

Distributions 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.

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 redemptions in kind, 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 for each Fund:

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation) on securities and other investments
Fidelity Corporate Bond ETF	$148,186,875	$10,338,537	$(354,554)	$9,983,983
Fidelity Limited Term Bond ETF	147,881,226	3,092,143	(10,496)	3,081,647

Fidelity Total Bond ETF	1,214,949,364	54,565,400	(5,040,752)	49,524,648

Capital loss carryforwards are only available to offset future capital gains of the Funds 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 fiscal period end and is subject to adjustment.

	No-expiration Short-term	No-expiration Long-term	Total capital loss carryforward

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. The securities purchased on a delayed delivery or when-issued basis are identified as such in each applicable Fund’s Schedule of Investments. Certain Funds may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. 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. 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.

To-Be-Announced (TBA) Securities and Mortgage Dollar Rolls. During the period, certain Funds transacted in TBA securities that involved 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. The Funds may enter into a TBA transaction with the intent to take possession of or deliver the underlying MBS, or the 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 each 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, the Funds' 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.

Restricted Securities. The 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 is included at the end of each applicable Fund's Schedule of Investments.

Loans and Other Direct Debt Instruments. The Funds invest in direct debt instruments which 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 the Funds to supply additional cash to the borrower on demand. Loans may be acquired through assignment or participation. The Funds also invest in unfunded loan commitments, which are contractual obligations for future funding. Information regarding unfunded commitments is included at the end of each Fund’s Schedule of Investments.

5. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) provides the Funds with investment management related services for which the Funds pay a monthly management fee that is based on an annual rate of .36% of each Fund's average net assets for Fidelity Corporate Bond ETF, Fidelity Limited Term Bond ETF and Fidelity Total Bond ETF. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense. The management fee paid to the investment adviser is reduced by an amount equal to the fees and expenses paid by each fund to the independent Trustees. Effective January 1, 2020, investment advisers Fidelity Investments Money Management, Inc., FMR Co., Inc., and Fidelity SelectCo, LLC, merged with and into Fidelity Management & Research Company. In connection with the merger transactions, the resulting, merged investment adviser was then redomiciled from Massachusetts to Delaware, changed its corporate structure from a corporation to a limited liability company, and changed its name to "Fidelity Management & Research Company LLC".

Fidelity Low Duration Bond Factor ETF's management fee is based on an annual rate of .15% of average net assets. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain miscellaneous expenses such as proxy and shareholders meeting expenses.

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. Interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note.

6. 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 Commitment fees on the Statements of Operations, and are as follows:

	Amount
Fidelity Corporate Bond ETF	$155
Fidelity Limited Term Bond ETF	173
Fidelity Total Bond ETF	950

During the period, there were no borrowings on this line of credit.

7. Expense Reductions.

Through arrangements with each applicable Fund’s custodian, credits realized as a result of certain uninvested cash balances were used to reduce each applicable Fund’s expenses by the following amounts:

	Amount
Fidelity Corporate Bond ETF	$1,121
Fidelity Limited Term Bond ETF	201
Fidelity Low Duration Bond Factor ETF	1,536
Fidelity Total Bond ETF	2,569

8. Share Transactions.

The Funds issue and redeem shares at NAV only with certain authorized participants in large increments known as Creation Units. Purchases of Creation Units are made by tendering a basket of designated securities and cash to a Fund and redemption proceeds are paid with a basket of securities from a fund's portfolio with a balancing cash component to equate the market value of the basket of securities delivered or redeemed to the NAV per Creation Unit on the transaction date. Cash may be substituted equivalent to the value of certain securities generally when they are not available in sufficient quantity for delivery. A fund's shares are available in smaller increments to investors in the secondary market at market prices and may be subject to commissions. Authorized participants pay a transaction fee to the shareholder servicing agent when purchasing and redeeming Creation Units of a fund. The transaction fee is used to defray the costs associated with the issuance and redemption of Creation Units.

9. Other.

The Funds' 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 Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds' maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

10. Credit Risk.

The Funds may invest a portion of their assets in structured securities of issuers backed by 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.

11. Coronavirus (COVID-19) Pandemic.

An outbreak of COVID-19 first detected in China during December 2019 has since spread globally and was declared a pandemic by the World Health Organization during March 2020. Developments that disrupt global economies and financial markets, such as the COVID-19 pandemic, may magnify factors that affect the Fund's performance.

Shareholder Expense Example (Unaudited)

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management 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 funds.

The Example is based on an investment of $1,000 invested for the one-half year period (September 1, 2019 to February 29, 2020).

Actual Expenses

For each fund, 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 each Fund under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period. In addition, each Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in each Fund’s annualized expense ratio used to calculate the expense estimates in the table below.

Hypothetical Example for Comparison Purposes

For each fund, the second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid 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. In addition, each Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in each Fund’s annualized expense ratio used to calculate the expense estimates 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.

	Annualized Expense Ratio^A	Beginning Account Value September 1, 2019	Ending Account Value February 29, 2020	Expenses Paid During Period^B September 1, 2019 to February 29, 2020
Fidelity Corporate Bond ETF	0.36%
Actual		$1,000.00	$1,043.00	$1.83

Hypothetical^C		$1,000.00	$1,023.07	$1.81

^A	Annualized expense ratio reflects expenses net of applicable fee waivers.
^B	Expenses are equal to each Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).
^C	5% return per year before expenses.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Corporate Bond ETF

Fidelity Limited Term Bond ETF

Fidelity Total Bond ETF

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Investments Money Management, Inc. (FIMM), an affiliate of Fidelity Management & Research Company (FMR), and the sub-advisory agreements (together, the Advisory Contracts) for each fund. FIMM 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 each fund’s Advisory Contracts, including the services and support provided to each 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 of the Independent Trustees are members, meets regularly throughout the year and considers, among other matters, information specifically related to the annual consideration of the renewal of each fund’s Advisory Contracts. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of each fund’s Advisory Contracts. 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 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 2019 meeting, the Board unanimously determined to renew each 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 each fund and its shareholders (including the investment performance of each fund); (ii) the competitiveness of each fund’s management fee and total expense ratio relative to peer funds; (iii) the total costs of the services provided by and the profits realized by Fidelity from its relationships with each fund; and (iv) the extent to which, if any, economies of scale exist and are realized as each fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

In considering whether to renew the Advisory Contracts for each 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 each 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 each fund have a broad range of investment choices available to them, including a wide choice among funds offered by Fidelity’s competitors, and that each 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 that fund, which is part of the Fidelity family of funds.

Approval of Amended and Restated Advisory Contracts. At its September 2019 meeting, the Board also unanimously determined to approve amended and restated management contracts and sub-advisory agreements (Amended and Restated Contracts) in connection with an upcoming consolidation of certain of Fidelity's advisory businesses. The Board considered that, on or about January 1, 2020, FIMM expects to merge with and into FMR and, after the merger, FMR expects to redomicile as a Delaware limited liability company. The Board noted that the Amended and Restated Contracts will reflect the replacement of FIMM with FMR and will take effect upon the completion of the merger. The Board noted that references to FMR in the Amended and Restated Contracts would be updated to reflect FMR’s new form of organization and domicile. The Board also approved amendments that clarify that each 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 also noted Fidelity’s assurance that neither the planned consolidation nor the Amended and Restated Contracts will change the investment processes, the level or nature of services provided, the resources and personnel allocated, trading and compliance operations, or any fees or expenses paid by the funds.

Nature, Extent, and Quality of Services Provided. The Board considered Fidelity’s staffing as it relates to the funds, including the backgrounds of investment personnel of Fidelity, and also considered the funds’ investment objectives, strategies, and related investment philosophies. 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 each fund. Additionally, the Board considered the portfolio managers’ investments, if any, in the funds that they manage.

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, 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 pricing and bookkeeping services for each fund; (ii) the nature and extent of the supervision of third party service providers, principally State Street Bank and Trust Company, each fund’s transfer agent and custodian, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, each 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, and the expanded availability of 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 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, and to the support of the senior management team that oversees asset management; (ii) continuing efforts to enhance Fidelity’s global research capabilities; (iii) launching new funds with innovative structures, strategies and pricing and making other enhancements to meet client needs; (iv) launching new share classes of existing funds; (v) eliminating purchase minimums and broadening eligibility requirements for certain funds and share classes; (vi) reducing management fees and total expenses for certain target date funds and index funds; (vii) lowering expense caps for certain existing funds and classes, and converting certain voluntary expense caps to contractual caps, to reduce expenses borne by shareholders; (viii) rationalizing product lines and gaining increased efficiencies from fund mergers, liquidations, and share class consolidations; (ix) continuing to develop, acquire and implement systems and technology to improve services to the funds and shareholders, strengthen information security, and increase efficiency; and (x) continuing to implement enhancements to further strengthen Fidelity’s product line to increase investors’ probability of success in achieving their investment goals, including retirement income goals.

Investment Performance. The Board considered whether each fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions and its performance history. The Board noted that there was a portfolio management change for Fidelity Total Bond ETF in March 2019.

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 each fund for different time periods, measured against an appropriate securities market index (benchmark index) and a peer group of funds with similar objectives (peer group), if any. 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 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. 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 each fund and an appropriate benchmark index for the most recent one- and three-year periods.

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

Competitiveness of Management Fee and Total Expense Ratio. The Board considered each fund’s management fee and total expense ratio compared to “mapped groups” of competitive funds and classes created for the purpose of facilitating the Trustees’ competitive analysis of management fees and total expenses. Fidelity creates “mapped groups” by combining similar Lipper investment objective categories that have comparable investment mandates. Combining Lipper investment objective categories aids the Board’s management fee and total expense ratio comparisons by broadening the competitive group used for comparison.

Management Fee. The Board considered two proprietary management fee comparisons for the 12-month (or shorter) periods shown in basis points (BP) in the charts below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the “Total Mapped Group.” 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 a 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 a fund. The funds’ actual TMG %s and the number of funds in the Total Mapped Group are in the charts below. The “Asset-Size 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 a fund’s management fee rate ranked, is also included in the charts and was considered by the Board.

Fidelity Corporate Bond ETF

At its March 2018 meeting, the Board approved an amended and restated management contract for the fund (effective April 1, 2018) that lowered the fund’s management fee rate from 0.45% to 0.36%. The Board considered that the chart below reflects the fund’s lower management fee rate for 2018, as if the lower fee were in effect for 2017.

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 2018.

Board Approval of Investment Advisory Contracts and Management Fees – continued

Based on its review, the Board concluded that each 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 each fund’s total expense ratio, the Board considered the fund’s all-inclusive fee rate. The Board also considered other expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FIMM under the all-inclusive arrangement. 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 each fund. As part of its review, the Board also considered the current and historical total expense ratios of each fund compared to competitive fund median expenses. Each fund is 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 noted that each fund’s total expense ratio ranked below the competitive median for 2018.

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 each 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 revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing each fund and servicing each 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 each 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.

PricewaterhouseCoopers LLP (PwC), auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board’s assessment of Fidelity’s profitability analysis. PwC’s engagement includes the review and assessment of the methodologies used by Fidelity in determining the revenues and expenses attributable to Fidelity’s mutual fund business, and completion of agreed-upon procedures in respect of the mathematical accuracy of the fund profitability information and its conformity to established allocation methodologies. After considering PwC’s reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity’s profitability methodologies are reasonable in all material respects.

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 noted that changes to fall-out benefits year-over-year reflect business developments at Fidelity’s various businesses. The Board considered that a joint ad hoc committee created by it and the boards of other Fidelity funds had recently been established, and meets periodically, to evaluate potential fall-out benefits. The Board noted that the committee was expected to, among other things: (i) discuss the legal framework surrounding potential fall-out benefits; (ii) review the Board’s responsibilities and approach to potential fall-out benefits; and (iii) review practices employed by competitor funds regarding the review of potential fall-out benefits. The Board noted that it would consider the committee’s findings in connection with future consideration of contract renewals.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of each 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 each 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 each 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 recognized that, due to each fund’s current contractual arrangements, its expense ratio will not decline if the fund’s operating costs decrease as assets grow, or rise as assets decrease. 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) Fidelity’s compensation structure for portfolio managers, research analysts, and other key personnel, including its effects on fund profitability, the rationale for the compensation structure, and the extent to which current market conditions have affected retention and recruitment; (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 practices of certain sub-advisers regarding their receipt of research from broker-dealers that execute the funds’ portfolio transactions; (vi) the terms of Fidelity’s voluntary expense limitation agreements; (vii) the methodology with respect to competitive fund data and peer group classifications; (viii) Fidelity’s transfer agent fee, expense, and service structures for different funds and classes relative to competitive trends, and the impact of the increased use of omnibus accounts; (ix) new developments in the retail and institutional marketplaces and the competitive positioning of the funds relative to other investment products and services; (x) the impact on fund profitability of recent changes in total net assets for Fidelity’s money market funds, anticipated changes to the competitive landscape for money market funds, and the level of investor comfort with gates, fees, and floating NAVs; (xi) the funds’ share class structures and distribution channels; and (xii) explanations regarding the relative total expense ratios of certain funds and classes, total expense competitive trends and methodologies for total expense competitive comparisons, and actions that might be taken by Fidelity to reduce total expense ratios for certain classes. In addition, the Board considered its discussions with Fidelity throughout the year regarding enhanced information security initiatives and the funds’ fair valuation policies.

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 each fund’s Advisory Contracts should be renewed and each fund’s Amended and Restated Contracts should be approved.

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Investments Money Management, Inc. (FIMM), an affiliate of Fidelity Management & Research Company (FMR), and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FIMM 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 of the Independent Trustees are members, meets regularly throughout the year and considers, among other matters, information specifically related to the annual consideration of the renewal of the fund’s Advisory Contracts. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund’s Advisory Contracts. 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 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 2019 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 of the fund’s management fee and total expense ratio relative to peer funds; (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.

Board Approval of Investment Advisory Contracts and Management Fees – continued

Approval of Amended and Restated Advisory Contracts. At its September 2019 meeting, the Board also unanimously determined to approve an amended and restated management contract and sub-advisory agreements (Amended and Restated Contracts) in connection with an upcoming consolidation of certain of Fidelity's advisory businesses. The Board considered that, on or about January 1, 2020, FIMM expects to merge with and into FMR and, after the merger, FMR expects to redomicile as a Delaware limited liability company. The Board noted that the Amended and Restated Contracts will reflect the replacement of FIMM with FMR and will take effect upon the completion of the merger. The Board noted that references to FMR in the Amended and Restated Contracts would be updated to reflect FMR’s new form of organization and domicile. The Board also approved amendments that clarify 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 also noted Fidelity’s assurance that neither the planned consolidation nor the Amended and Restated Contracts will change the investment processes, the level or nature of services provided, the resources and personnel allocated, trading and compliance operations, or any fees or expenses paid by the fund.

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.

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, managing, and compensating investment personnel. The Board noted that Fidelity has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity’s global investment organization. The Board also noted that Fidelity’s analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated 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, 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 pricing and bookkeeping services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally State Street Bank and Trust Company, the fund’s transfer agent and custodian, 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. As the fund recently commenced operations, the Board did not believe that it was appropriate to assign significant weight to its limited investment performance. The Board considered the Investment Advisers’ strength in fundamental, research-driven security selection, with which the Board is familiar through its supervision of other Fidelity funds.

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 “mapped groups” of competitive funds and classes created for the purpose of facilitating the Trustees’ competitive analysis of management fees and total expenses. Fidelity creates “mapped groups” by combining similar Lipper investment objective categories that have comparable investment mandates. Combining Lipper investment objective categories aids the Board’s management fee and total expense ratio comparisons by broadening the competitive group used for comparison.

Management Fee. The Board considered two proprietary management fee comparisons for the period of the fund’s operations 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.” 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 % and the number of funds in the Total Mapped Group are in the chart below. The "Asset-Size 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.

Fidelity Low Duration Bond Factor ETF

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 the period.

The Board noted that it and the boards of other Fidelity funds formed an ad hoc Committee on Group Fee, which meets periodically, to conduct an in-depth review of the “group fee” component of the management fee of funds with such management fee structures. The Committee's focus included the mechanics of the group fee, the competitive landscape of group fee structures, Fidelity funds with no group fee component (such as the fund) and investment products not included in group fee assets. The Board also considered that, for funds subject to the group fee, FMR agreed to voluntarily waive fees over a specified period of time in amounts designed to account for assets converted from certain funds to certain collective investment trusts.

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 fund’s total expense ratio, the Board considered the fund’s all-inclusive fee rate. The Board also considered other expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FIMM under the all-inclusive arrangement. 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. As part of its review, the Board also considered the current total expense ratio of the fund compared to competitive fund median expenses. The fund is 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 noted that the fund’s total expense ratio ranked below the competitive median for the period.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board 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 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 fund’s business. The Board noted that changes to fall-out benefits year-over-year reflect business developments at Fidelity’s various businesses. The Board considered that a joint ad hoc committee created by it and the boards of other Fidelity funds had recently been established, and meets periodically, to evaluate potential fall-out benefits. The Board noted that the committee was expected to, among other things: (i) discuss the legal framework surrounding potential fall-out benefits; (ii) review the Board’s responsibilities and approach to potential fall-out benefits; and (iii) review practices employed by competitor funds regarding the review of potential fall-out benefits. The Board noted that it would consider the committee’s findings in connection with future consideration of contract renewals.

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 recognized that, due to the fund’s current contractual arrangements, its expense ratio will not decline if the fund’s operating costs decrease as assets grow, or rise as assets decrease. 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.

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) Fidelity’s compensation structure for portfolio managers, research analysts, and other key personnel, including its effects on fund profitability, the rationale for the compensation structure, and the extent to which current market conditions have affected retention and recruitment; (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 practices of certain sub-advisers regarding their receipt of research from broker-dealers that execute the funds’ portfolio transactions; (vi) the terms of Fidelity’s voluntary expense limitation agreements; (vii) the methodology with respect to competitive fund data and peer group classifications; (viii) Fidelity’s transfer agent fee, expense, and service structures for different funds and classes relative to competitive trends, and the impact of the increased use of omnibus accounts; (ix) new developments in the retail and institutional marketplaces and the competitive positioning of the funds relative to other investment products and services; (x) the impact on fund profitability of recent changes in total net assets for Fidelity’s money market funds, anticipated changes to the competitive landscape for money market funds, and the level of investor comfort with gates, fees, and floating NAVs; (xi) the funds’ share class structures and distribution channels; and (xii) explanations regarding the relative total expense ratios of certain funds and classes, total expense competitive trends and methodologies for total expense competitive comparisons, and actions that might be taken by Fidelity to reduce total expense ratios for certain classes. In addition, the Board considered its discussions with Fidelity throughout the year regarding enhanced information security initiatives and the funds’ fair valuation policies.

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 and the fund’s Amended and Restated Contracts should be approved.

Liquidity Risk Management Program

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 Funds have adopted and implemented a liquidity risk management program pursuant to the Liquidity Rule (the Program) effective December 1, 2018. The Program is reasonably designed to assess and manage each Fund’s liquidity risk and to comply with the requirements of the Liquidity Rule. Each Fund’s Board of Trustees (the Board) has designated each 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) in the case of exchange-traded funds, certain additional factors 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 liquidity categories described below 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 not 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 implementation of the Program for the annual period from December 1, 2018 through November 30, 2019. The report concluded that the Program has been implemented and is operating effectively and is reasonably designed to assess and manage the Fund’s liquidity risk.
