Euclid Capital Growth ETF

NOTES TO FINANCIAL STATEMENTS May 31, 2022 (Unaudited)

NOTE 1 – ORGANIZATION

The Euclid Capital Growth ETF (the “Fund”) is a non-diversified series of shares of beneficial interest of Tidal ETF Trust (the “Trust”). The Trust was organized as a Delaware statutory trust on June 4, 2018 and is registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company and the offering of the Fund’s shares is registered under the Securities Act of 1933, as amended. The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 “Financial Services—Investment Companies.” The Fund commenced operations on December 31, 2020.

The investment objective of the Fund is to seek capital appreciation.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Fund.These policies are in conformity with accounting principles generally accepted in the United States of America (“U.S.GAAP”).

A.Security Valuation.Equity securities, which may include Real Estate Investment Trusts (“REITs”), Business Development Companies (“BDCs”), and Master Limited Partnerships (“MLPs”), listed on a securities exchange, market or automated quotation system for which quotations are readily available (except for securities traded on the NASDAQ Stock Market, LLC (“NASDAQ”)), including securities traded over the counter, are valued at the last quoted sale price on the primary exchange or market (foreign or domestic) on which they are traded on the valuation date (or at approximately 4:00 p.m. EST if a security’s primary exchange is normally open at that time), or, if there is no such reported sale on the valuation date, at the most recent quoted bid price or mean between the most recent quoted bid and ask prices for long and short positions. For a security that trades on multiple exchanges, the primary exchange will generally be considered the exchange on which the security is generally most actively traded. For securities traded on NASDAQ, the NASDAQ Official Closing Price will be used. Prices of securities traded on the securities exchange will be obtained from recognized independent pricing agents (“Independent Pricing Agents”) each day that the Fund is open for business.

For securities for which quotations are not readily available, a fair value will be determined by the Valuation Committee using the Fair Value Procedures approved by the Trust’s Board of Trustees (the “Board”). When a security is “fair valued,” consideration is given to the facts and circumstances relevant to the particular situation, including a review of various factors set forth in the Fair Value Procedures adopted by the Board. Fair value pricing is an inherently subjective process, and no single standard exists for determining fair value. Different funds could reasonably arrive at different values for the same security. The use of fair value pricing by a fund may cause the net asset value of its shares to differ significantly from the net asset value that would be calculated without regard to such considerations.

As described above, the Fund utilizes various methods to measure the fair value of its investments on a recurring basis. U.S. GAAP establishes a hierarchy that prioritizes inputs to valuation methods. The three levels of inputs are:

Level 1 –Unadjusted quoted prices in active markets for identical assets or liabilities that the Fund has the ability to access.

Level 2 –Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

Level 3 –Unobservable inputs for the asset or liability, to the extent relevant observable inputs are not available; representing the Fund’s own assumptions about the assumptions a market participant would use in valuing the asset or liability and would be based on the best information available.

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

8

Euclid Capital Growth ETF

The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety, is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The following is a summary of the inputs used to value the Fund’s investments as of May 31, 2022:

Investments in Securities	Level 1	Level 2	Level 3	Total
Common Stock	$2,275,468	—	—	$2,275,468
Exchange Traded Funds	5,723,706	—	—	5,723,706
Short-Term Investments	1,080,577	—	—	1,080,577
Total Investments in Securities	$9,079,751	$—	$—	$9,079,751

B.Federal Income Taxes. The Fund has elected to be taxed as a “regulated investment company” and intends to distribute substantially all taxable income to its shareholders and otherwise comply with the provisions of the Internal Revenue Code applicable to regulated investment companies. Therefore, no provision for federal income taxes or excise taxes has been made.

In order to avoid imposition of the excise tax applicable to regulated investment companies, the Fund intends to declare as dividends in each calendar year at least 98.0% of its net investment income (earned during the calendar year) and at least 98.2% of its net realized capital gains (earned during the twelve months ended November 30) plus undistributed amounts, if any, from prior years.

As of May 31, 2022, the Fund did not have any tax positions that did not meet the threshold of being sustained by the applicable tax authority. Generally, tax authorities can examine all the tax returns filed for the last three years. The Fund identifies its major tax jurisdiction as U.S. Federal and the Commonwealth of Delaware; however, the Fund is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially.

C.Securities Transactions and Investment Income. Investment securities transactions are accounted for on the trade date. Gains and losses realized on sales of securities are determined on a specific identification basis. Discounts/premiums on debt securities purchased are accreted/amortized over the life of the respective securities using the effective interest method. Dividend income is recorded on the ex-dividend date. Dividends received from REITs generally are comprised of ordinary income, capital gains, and may include return of capital. Debt income is recorded on an accrual basis. Other non-cash dividends are recognized as investment income at the fair value of the property received. Withholding taxes on foreign dividends have been provided for in accordance with the Trust’s understanding of the applicable country’s tax rules and rates.

D.Distributions to Shareholders. Distributions to shareholders from net investment income, if any, for the Fund are declared and paid at least annually. Distributions to shareholders from net realized gains on securities, if any, for the Fund normally are declared and paid on an annual basis. Distributions are recorded on the ex-dividend date.

E.Use of Estimates.The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses during the reporting period. Actual results could differ from those estimates.

F.Share Valuation.The net asset value (“NAV”) per share of the Fund is calculated by dividing the sum of the value of the securities held by the Fund, plus cash or other assets, minus all liabilities by the total number of shares outstanding for the Fund, rounded to the nearest cent. The Fund’s shares will not be priced on the days on which the New York Stock Exchange (“NYSE”) is closed for trading.

G.Guarantees and Indemnifications.In the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote.

H.Illiquid Securities.Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a Board-approved Liquidity Risk Management Program (the “Program”) that requires, among other things, that the Fund limit its illiquid investments that are assets to no more than 15% of the value of the Fund’s net assets. An illiquid investment is any security that the Fund reasonably expects cannot

NOTES TO FINANCIAL STATEMENTS May 31, 2022 (Unaudited) (Continued)

Euclid Capital Growth ETF

be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. If the Fund should be in a position where the value of illiquid investments held by the Fund exceeds 15% of the Fund’s net assets, the Fund will take such steps as set forth in the Program.

I.Recently Issued Accounting Pronouncements. In October 2020, the SEC adopted new regulations governing the use of derivatives by registered investment companies (“Rule 18f-4”).The Fund will be required to implement and comply with Rule 18f-4 by August 19, 2022.Once implemented, Rule 18f-4 will impose limits on the amount of derivatives a fund can enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as senior securities and require funds whose use of derivatives is more than a limited specified exposure amount to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager.Management is currently evaluating the impact, if any, of applying this provision.

In December 2020, the SEC adopted a new rule providing a framework for fund valuation practices (“Rule 2a-5”).Rule 2a-5 establishes requirements for determining fair value in good faith for purposes of the 1940 Act.Rule 2a-5 will permit fund boards to designate certain parties to perform fair value determinations, subject to board oversight and certain other conditions.Rule 2a-5 also defines when market quotations are “readily available” for purposes of the 1940 Act and the threshold for determining whether a fund must fair value a security.In connection with Rule 2a-5, the SEC also adopted related recordkeeping requirements and is rescinding previously issued guidance, including with respect to the role of a board in determining fair value and the accounting and auditing of fund investments.The Fund will be required to comply with the rules by September 8, 2022.Management is currently evaluating the impact, if any, of applying this provision.

NOTE 3 – PRINCIPAL INVESTMENTS RISKS

A.Asset Allocation Risk.The Fund may favor an asset class or investment style that performs poorly relative to other asset classes and investment styles for short or long periods of time. Additionally, because the Fund may weight certain asset classes or investment styles at zero, the Fund may miss positive changes in an asset class’ or investment style’s performance and fail to capture upside performance for an asset class or investment style.

B.Emerging Market Risk.The Fund may invest in shares of ETFs that seek to track various indices (“Underlying ETFs”) that invest in securities issued by companies domiciled or headquartered in emerging market nations. Investments in securities traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, currency, or regulatory conditions not associated with investments in U.S. securities and investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund Shares and cause the Fund to decline in value.

C.Equity Markets Risk.The equity securities held by the Underlying ETFs in which the Fund invests may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which an Underlying ETF invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. Securities in an Underlying ETF’s portfolio may underperform in comparison to securities in the general securities markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, or government controls.

D.Exchange-Traded Fund (“ETF”) Risks.

•Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk.The Fund has a limited number of financial institutions that are authorized to purchase and redeem shares of the Fund (“Shares”) directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

NOTES TO FINANCIAL STATEMENTS May 31, 2022 (Unaudited) (Continued)

10

Euclid Capital Growth ETF

•Costs of Buying or Selling Shares.Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

•Shares May Trade at Prices Other Than NAV.As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

•Trading.Although Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

E.Fixed Income Securities Risk. The Fund may invest in Underlying ETFs that invest in fixed income securities. The prices of fixed income securities may be affected by changes in interest rates, the creditworthiness and financial strength of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing fixed income securities to fall and often has a greater impact on longer-duration and/or higher quality fixed income securities. Falling interest rates will cause an Underlying ETF to reinvest the proceeds of fixed income securities that have been repaid by the issuer at lower interest rates and may also reduce such Underlying ETF’s distributable income because interest payments on floating rate fixed income instruments held by the Underlying ETF will decline. The Fund could lose money on indirect investments in fixed income securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner.

F.Foreign Securities Risks.Foreign securities held by Underlying ETFs in which the Fund invests involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices.

G.Market Capitalization Risk. These risks apply to the extent the Underlying ETFs in which the Fund invests hold securities of large-, mid- and small-capitalization companies.

•Large-Capitalization Investing.The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

•Mid-Capitalization Investing.The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of midcapitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

•Small-Capitalization Investing.The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

H.MLP Risk. The Fund’s exposure to MLPs held by Underlying ETFs in which the Fund invests may subject the Fund to greater volatility than investments in traditional securities. The value of MLPs and MLP based exchange traded funds and notes may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting

NOTES TO FINANCIAL STATEMENTS May 31, 2022 (Unaudited) (Continued)

11

Euclid Capital Growth ETF

a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs, and international economic, political and regulatory developments. To the extent the Underlying ETFs’ investments in MLPs expose the Fund’s portfolio to the energy sector, such as the oil and gas industries, the Fund may experience additional risks related to these industries.

I.Models and Data Risk. The composition of the Fund’s portfolio is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Fund’s portfolio universe that would have been excluded or included had the Models and Data been correct and complete.

J.Non-Diversification Risk.Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

K.REIT Risk.A REIT is a company that owns or finances income-producing real estate. The Fund may invest in Underlying ETFs that invest in REITs. Through the Underlying ETFs’ investments in REITs, the Fund is subject to the risks of investing in the real estate market, including decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters. REITs are subject to additional risks, including those related to adverse governmental actions; declines in property value and the real estate market; the potential failure to qualify for tax-free pass through of income; and exemption from registration as an investment company. In addition, REITs have their own expenses, and an Underlying ETF that invests in REITs will bear a proportionate share of those expenses, in addition to the expenses of the Underlying ETF.

L.Sector Risk.At times, the Fund may increase the relative emphasis of its investments in a particular sector or group of industries. The prices of securities of issuers in a particular sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of Shares may fluctuate in response to events affecting that industry or sector.

M.Style Risk.At times, the Fund may increase the relative emphasis of its investments in a particular style, such as value-oriented or growth-oriented stocks. Certain styles of investing may over time go in and out of favor. To the extent the Fund favors a particular style that is out of favor, the Fund may underperform other funds that use different investing styles.

N.Underlying ETFs Risks. The Fund will incur higher and duplicative expenses because it invests in Underlying ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the Underlying ETFs. The Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by the Underlying ETFs. Additionally, Underlying ETFs are also subject to the “ETF Risks” described above.

NOTE 6 – INCOME TAXES AND DISTRIBUTIONS TO SHAREHOLDERS

The Fund is subject to examination by U.S. taxing authorities for the tax periods since the commencement of operations. The amount and character of tax basis distributions and composition of net assets, including undistributed (accumulated) net investment income (loss), are finalized at the fiscal year-end; accordingly, tax basis balances have not been determined for the period ended May 31, 2021.

The tax character of distributions paid during the six-months ended May 31, 2022 (estimated) and the period ended November 30, 2021, was as follows:

Distributions paid from:	May 31, 2022	November 30, 2021

Other accumulated gain (loss)	(13,717	)
Total accumulated gain (loss)	$901,606

⁽¹⁾The difference between book and tax-basis unrealized appreciation was attributable primarily to the treatment of wash sales.

NOTE 7 – SHARE TRANSACTIONS

Shares of the Fund are listed and traded on the Exchange. Market prices for the shares may be different from their NAV. The Fund issues and redeems shares on a continuous basis at NAV generally in large blocks of shares (“Creation Units”). Creation Units are issued and redeemed principally in-kind for securities included in a specified universe. Once created, shares generally trade in the secondary market at market prices that change throughout the day. Except when aggregated in Creation Units, shares are not redeemable securities of the Fund. Creation Units may only be purchased or redeemed by Authorized Participants. An Authorized Participant is either (i) a brokerdealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation or (ii) a Depository Trust Company participant and, in each case, must have executed a Participant Agreement with the Distributor. Most retail investors do not qualify as Authorized Participants nor have the resources to buy and sell whole Creation Units. Therefore, they are unable to purchase or redeem the shares directly from the Fund. Rather, most retail investors may purchase shares in the secondary market with the assistance of a broker and are subject to customary brokerage commissions or fees.

The Fund currently offers one class of shares, which has no front-end sales load, no deferred sales charge, and no redemption fee. A fixed transaction fee is imposed for the transfer and other transaction costs associated with the purchase or sale of Creation Units. The standard fixed transaction fee for the Fund is $250, payable to the Custodian. The fixed transaction fee may be waived on certain orders if the Fund’s Custodian has determined to waive some or all of the costs associated with the order or another party, such as the Adviser, has agreed to pay such fee. In addition, a variable fee may be charged on all cash transactions or substitutes for Creation Units and Redemption Units of up to a maximum of 2% of the value of the Creation Units and Redemption Units subject to the transaction. Variable fees received by the Fund, if any, are disclosed in the capital shares transactions section of the Statement of Changes in Net Assets. The Fund may issue an unlimited number of shares of beneficial interest, with no par value. All shares of the Fund have equal rights and privileges.

NOTE 8 – RECENT MARKET EVENTS

U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of COVID-19 as a global pandemic and related public health crisis, growth concerns in the U.S. and overseas, uncertainties regarding interest rates, rising inflation, trade tensions, and the threat of tariffs imposed by the U.S. and other countries. In particular, the global spread of COVID-19 has resulted in disruptions to business operations and supply chains, stress on the global healthcare system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. The global recovery from COVID-19 is proceeding at slower than expected rates due to the emergence of variant strains and may last for an extended period of time. Health crises and related political, social and economic disruptions caused by the spread of COVID-19 may also exacerbate other pre-existing political, social and economic risks in certain countries. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions,

14

Euclid Capital Growth ETF

NOTES TO FINANCIAL STATEMENTS May 31, 2022 (Unaudited) (Continued)

and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. These developments, as well as other events, could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets, despite government efforts to address market disruptions. Continuing market volatility as a result of recent market conditions or other events may have adverse effects on your account.

NOTE 9 – SUBSEQUENT EVENTS

In preparing these financial statements, the Fund has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued.

On July 11, 2022, the Board of Trustees of the Trust approved, via unanimous written consent, a Plan of Liquidation and Termination to close and liquidate the Fund. Pursuant to the Plan, the Fund will be liquidated on August 4, 2022, or such other date as determined by the Trust’s officers.

EXPENSE EXAMPLE For the Period Ended May 31, 2022 (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions paid on purchases and sales of the Fund’s shares, and (2) ongoing costs, including management fees of the Fund. The example is intended to help you understand your ongoing costs (in dollars) of investing in the 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 at the beginning of the period and held for the entire period, which is from December 1, 2021 to May 31, 2022.

Actual Expenses

The first line of the following table provides information about actual account values and actual expenses. To the extent the Fund invests in shares of other investment companies as part of its investment strategy, you will indirectly you’re your proportionate share of any fees and expenses charged by the underlying funds in which the Fund invests in addition to the expenses of the Fund. Actual expenses of the underlying funds are expected to vary among the various underlying funds. These expenses are not included in the example. The example includes, but is not limited to, unitary fees. However, the example does not include portfolio trading commissions and related 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 (for example, an $8,600 account value divided by $1,000 = 8.6), then, multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Period’’ to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the following 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. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions paid on purchases and sales of the Fund’s shares. Therefore, the second line of the following table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If these transactional costs were included, your costs would have been higher.

	Beginning Account Value December 1, 2021	Ending Account Value May 31, 2022	Expenses Paid During the Period December 1, 2021 – May 31, 2022(1)
Actual	$1,000.00	$  794.30	$2.91
Hypothetical (5% annual return before expenses)	$1,000.00	$1,021.69	$3.28

⁽¹⁾Expenses are equal to the Fund’s annualized net expense ratio for the most recent six-month period of 0.65%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the most recent six-month period).
