* Commencement of investment operations.

(a) Net investment income per share is based on average shares outstanding.

(b) Not annualized for periods less than one year.

(c) Annualized for periods less than one year.

(d) Net asset value total return is calculated assuming an initial investment made at the net asset value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at adjusted net asset value.

(e) Market value total return is calculated assuming an initial investment made at the market value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at market value. Market value is determined by the mid point of the bid/ask spread at 4:00 p.m. Eastern Time from the primary listing exchange. Market value returns may vary from net asset value returns.

(f) In-kind transactions are not included in portfolio turnover calculations.

(g) The amount shown for a share outstanding throughout the period is directionally inconsistent with aggregate net realized and unrealized gain (loss) for the period as presented in the financial statements.

(h) Per share amount is less than $0.005.

(i) The Fund indirectly bears its proportionate share of fees and expenses incurred by the Underlying Fund(s) in which the Fund is invested. This ratio does not include these indirect fees and expenses.

(j) The Expenses net of reimbursements and Net investment Income (Loss) net of reimbursement ratios include a voluntary reimbursement of advisory fees made by JPMorgan Chase Bank, N.A. Absent this additional reimbursement, Expenses net of reimbursements would have increased by 0.20% and the Net investment Income (Loss) net of reimbursement would have decreased by 0.20%.

(k) Northern Trust Investments, Inc. reimbursed the Funds for losses incurred related to an error. The impact was an increase of $0.02 to the net realized and unrealized gain (loss) on investments per share and an increase of 0.06% to the total return of the FlexShares Morningstar Global Upstream Natural Resources Index Fund. For the FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund and FlexShares STOXX Global ESG Select Index Fund, the impact to the net realized and unrealized gain (loss) on investments per share amount is less than $0.005 and the total returns are less than 0.005%. Had these reimbursements not been made, the total returns would have been lower.

* Commencement of investment operations.

(a) Net investment income per share is based on average shares outstanding.

(b) Not annualized for periods less than one year.

(c) Annualized for periods less than one year.

(d) Net asset value total return is calculated assuming an initial investment made at the net asset value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at adjusted net asset value.

(e) Market value total return is calculated assuming an initial investment made at the market value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at market value. Market value is determined by the mid point of the bid/ask spread at 4:00 p.m. Eastern Time from the primary listing exchange. Market value returns may vary from net asset value returns.

(f) In-kind transactions are not included in portfolio turnover calculations.

(g) The amount shown for a share outstanding throughout the period is directionally inconsistent with aggregate net realized and unrealized gain (loss) for the period as presented in the financial statements.

(h) Per share amount is less than $0.005.

(i) The Fund indirectly bears its proportionate share of fees and expenses incurred by the Underlying Fund(s) in which the Fund is invested. This ratio does not include these indirect fees and expenses.

(j) The Expenses net of reimbursements and Net investment Income (Loss) net of reimbursement ratios include a voluntary reimbursement of advisory fees made by JPMorgan Chase Bank, N.A. Absent this additional reimbursement, Expenses net of reimbursements would have increased by 0.20% and the Net investment Income (Loss) net of reimbursement would have decreased by 0.20%.

(k) Northern Trust Investments, Inc. reimbursed the Funds for losses incurred related to an error. The impact was an increase of $0.02 to the net realized and unrealized gain (loss) on investments per share and an increase of 0.06% to the total return of the FlexShares Morningstar Global Upstream Natural Resources Index Fund. For the FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund and FlexShares STOXX Global ESG Select Index Fund, the impact to the net realized and unrealized gain (loss) on investments per share amount is less than $0.005 and the total returns are less than 0.005%. Had these reimbursements not been made, the total returns would have been lower.

* Commencement of investment operations.

(a) Net investment income per share is based on average shares outstanding.

(b) Not annualized for periods less than one year.

(c) Annualized for periods less than one year.

(d) Net asset value total return is calculated assuming an initial investment made at the net asset value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at adjusted net asset value.

(e) Market value total return is calculated assuming an initial investment made at the market value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at market value. Market value is determined by the mid point of the bid/ask spread at 4:00 p.m. Eastern Time from the primary listing exchange. Market value returns may vary from net asset value returns.

(f) In-kind transactions are not included in portfolio turnover calculations.

(g) The amount shown for a share outstanding throughout the period is directionally inconsistent with aggregate net realized and unrealized gain (loss) for the period as presented in the financial statements.

(h) Per share amount is less than $0.005.

(i) The Fund indirectly bears its proportionate share of fees and expenses incurred by the Underlying Fund(s) in which the Fund is invested. This ratio does not include these indirect fees and expenses.

(j) The Expenses net of reimbursements and Net investment Income (Loss) net of reimbursement ratios include a voluntary reimbursement of advisory fees made by JPMorgan Chase Bank, N.A. Absent this additional reimbursement, Expenses net of reimbursements would have increased by 0.20% and the Net investment Income (Loss) net of reimbursement would have decreased by 0.20%.

(k) Northern Trust Investments, Inc. reimbursed the Funds for losses incurred related to an error. The impact was an increase of $0.02 to the net realized and unrealized gain (loss) on investments per share and an increase of 0.06% to the total return of the FlexShares Morningstar Global Upstream Natural Resources Index Fund. For the FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund and FlexShares STOXX Global ESG Select Index Fund, the impact to the net realized and unrealized gain (loss) on investments per share amount is less than $0.005 and the total returns are less than 0.005%. Had these reimbursements not been made, the total returns would have been lower.

* Commencement of investment operations.

(a) Net investment income per share is based on average shares outstanding.

(b) Not annualized for periods less than one year.

(c) Annualized for periods less than one year.

(d) Net asset value total return is calculated assuming an initial investment made at the net asset value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at adjusted net asset value.

(e) Market value total return is calculated assuming an initial investment made at the market value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period and redemption on the last day of the period at market value. Market value is determined by the mid point of the bid/ask spread at 4:00 p.m. Eastern Time from the primary listing exchange. Market value returns may vary from net asset value returns.

(f) In-kind transactions are not included in portfolio turnover calculations.

(g) The amount shown for a share outstanding throughout the period is directionally inconsistent with aggregate net realized and unrealized gain (loss) for the period as presented in the financial statements.

(h) Per share amount is less than $0.005.

(i) The Fund indirectly bears its proportionate share of fees and expenses incurred by the Underlying Fund(s) in which the Fund is invested. This ratio does not include these indirect fees and expenses.

(j) The Expenses net of reimbursements and Net investment Income (Loss) net of reimbursement ratios include a voluntary reimbursement of advisory fees made by JPMorgan Chase Bank, N.A. Absent this additional reimbursement, Expenses net of reimbursements would have increased by 0.20% and the Net investment Income (Loss) net of reimbursement would have decreased by 0.20%.

(k) Northern Trust Investments, Inc. reimbursed the Funds for losses incurred related to an error. The impact was an increase of $0.02 to the net realized and unrealized gain (loss) on investments per share and an increase of 0.06% to the total return of the FlexShares Morningstar Global Upstream Natural Resources Index Fund. For the FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund and FlexShares STOXX Global ESG Select Index Fund, the impact to the net realized and unrealized gain (loss) on investments per share amount is less than $0.005 and the total returns are less than 0.005%. Had these reimbursements not been made, the total returns would have been lower.

Notes to the Financial Statements April 30, 2021 (Unaudited)

1. Organization

FlexShares^® Trust (the “Trust”), a Maryland statutory trust, was formed on May 13, 2010, originally named NT ETF Trust and renamed FlexShares^® Trust as of April 12, 2011. The Trust is registered as an open-end management investment company under the Investment Company Act of 1940 (the “1940 Act”), as amended. The Trust consists of twenty-seven operational exchange-traded funds as of April 30, 2021 (each a “Fund” and collectively, the “Funds”).

The FlexShares^® US Quality Low Volatility Index Fund, FlexShares^® Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares^® Emerging Markets Quality Low Volatility Index Fund, FlexShares^® Morningstar Global Upstream Natural Resources Index Fund, FlexShares^® STOXX^® Global Broad Infrastructure Index Fund, FlexShares^® Global Quality Real Estate Index Fund, FlexShares^® Real Assets Allocation Index Fund, FlexShares^® iBoxx 3-Year Target Duration TIPS Index Fund, FlexShares^® iBoxx 5-Year Target Duration TIPS Index Fund, FlexShares^® Credit-Scored US Corporate Bond Index Fund, FlexShares^® Credit-Scored US Long Corporate Bond Index Fund, and the FlexShares^® Ready Access Variable Income Fund are non-diversified series of the Trust, pursuant to the 1940 Act.

The FlexShares^® Morningstar US Market Factor Tilt Index Fund, FlexShares^® Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares^® Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares^® US Quality Large Cap Index Fund, FlexShares^® STOXX^® US ESG Select Index Fund (formerly known as the FlexShares^® STOXX^® US ESG Impact Index Fund), FlexShares^® STOXX^® Global ESG Select Index Fund (formerly known as the FlexShares^® STOXX^® Global ESG Impact Index Fund), FlexShares^® Quality Dividend Index Fund, FlexShares^® Quality Dividend Defensive Index Fund, FlexShares^® Quality Dividend Dynamic Index Fund, FlexShares^® International Quality Dividend Index Fund, FlexShares^® International Quality Dividend Defensive Index Fund, FlexShares^® International Quality Dividend Dynamic Index Fund, FlexShares^® Disciplined Duration MBS Index Fund, FlexShares^® High Yield Value-Scored Bond Index Fund and the FlexShares^® Core Select Bond Fund are diversified series of the Trust, pursuant to the 1940 Act.

Each Fund, except the FlexShares Ready Access Variable Income Fund and the FlexShares Core Select Bond Fund, seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index (each an “Underlying Index”). The FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares Credit-Scored US Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund and the FlexShares High Yield Value-Scored Bond Index Fund seek to track Underlying Indexes developed by Northern Trust Investments, Inc. (“NTI” or “Investment Adviser”), an indirect subsidiary of Northern Trust Corporation. The FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund and FlexShares Morningstar Global Upstream Natural Resources Index Fund seek to track Underlying Indexes sponsored by Morningstar, Inc. The FlexShares STOXX^® US ESG Select Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, and FlexShares STOXX^® Global Broad Infrastructure Index Fund seek to track Underlying Indexes sponsored by STOXX. The FlexShares iBoxx 3-Year Target Duration TIPS Index Fund and FlexShares iBoxx 5-Year Target Duration TIPS Index Fund seek to track Underlying Indexes sponsored by Markit Indexes Limited. The FlexShares Disciplined Duration MBS Index Fund seeks to track an Underlying Index sponsored by ICE Data Indexes, LLC.

The FlexShares Real Assets Allocation Index Fund is a fund of funds that seeks its investment objective by investing primarily in the shares of other FlexShares ETFs that are eligible for inclusion in its Underlying Index, rather than in

336 FLEXSHARES SEMIANNUAL REPORT

Notes to the Financial Statements (cont.)

securities of individual companies. The FlexShares Core Select Bond Fund seeks to achieve its investment objective by investing, under normal circumstances in U.S. dollar-denominated investment-grade fixed-income securities either directly or indirectly through FlexShares ETFs, unaffiliated ETFs and other registered investment companies. The investment performance of each of the FlexShares Real Assets Allocation Index Fund and FlexShares Core Select Bond Fund is directly related to the performance of the underlying fund(s) in which it invests (“Underlying Fund”).

The FlexShares Ready Access Variable Income Fund and the FlexShares Core Select Bond Fund are actively managed and do not seek to replicate the performance of a specified index. The FlexShares Ready Access Variable Income Fund seeks maximum current income consistent with the preservation of capital and liquidity. The FlexShares Core Select Bond Fund seeks total return and preservation of capital. Each Fund, except the FlexShares Ready Access Variable Income Fund and the FlexShares Core Select Bond Fund, is referred to herein as an “Index Fund.” Each Fund is managed by the Investment Adviser.

2. Significant Accounting Policies

The Trust, which is an investment company, follows accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

Investment Valuation

Each Fund’s Net Asset Value (“NAV”) is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading, based on prices at the

time of closing provided that any U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments on any day that the Securities Industry and Financial Markets Association announces an early closing time. The NAV of a Fund is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.

The investments of the Funds are valued at fair value pursuant to the pricing policy and procedures approved by the Trust’s Board of Trustees (“Board”). The Funds’ investments are valued using market quotations when available. When market quotations are not readily available, are deemed unreliable, or do not reflect material events occurring between the close of local markets and the time of valuation, the Funds value securities at fair value as determined in good faith in accordance with the Funds’ fair value pricing procedures as approved by the Board. Such circumstances include periods when trading in a security is suspended, the exchange or market on which a security trades closes early, the trading volume in a security is limited, corporate actions and announcements take place, or regulatory news affecting an issuer is released, such as government approvals. Additionally, the Trust, in its discretion, may make adjustments to the prices of securities held by a Fund if an event occurs after the publication of market values normally used by a Fund but before the time as of which the Fund calculates its NAV, depending on the nature and significance of the event, consistent with applicable regulatory guidance and the Trust’s fair value procedures. Other events that can trigger fair valuing of foreign securities include, for example, significant fluctuations in general market indicators, government actions, or natural disasters.

The use of fair valuation involves the risk that the values used by the Funds to price their investments may be higher or lower than the values used by other investment companies and investors to price the same investments. Fair value pricing involves subjective judgments and it is possible that a fair value determination for a portfolio security may be materially different than the value that could be realized upon the sale of such security. In addition, fair value pricing

FLEXSHARES SEMIANNUAL REPORT 337

Notes to the Financial Statements (cont.)

could result in a difference between the prices used to calculate a Fund’s NAV and the prices used by an Index Fund’s Underlying Index. This difference may adversely affect an Index Fund’s ability to track its Underlying Index. Portfolio securities of certain Funds are listed on foreign exchanges and their value may change on days when shareholders will not be able to purchase or sell Fund shares.

Security prices are generally provided by independent pricing services. Portfolio securities listed or traded on domestic securities exchanges or the NASDAQ/NMS, including dollar-denominated foreign securities or American Depositary Receipts (“ADRs”), are valued at the closing price, or last sale price, reported on the exchange or system where the security is principally traded. The closing price for securities traded on the NASDAQ/NMS is the Nasdaq Official Closing Price (“NOCP”). If there have been no sales for that day on the exchange or system where the security is principally traded, then the value is determined with reference to the last sale price, or the NOCP, if applicable, on any other exchange or system. If there have been no sales of the security for that day on any exchange or system, the security is valued at fair value pursuant to the Trust’s fair value procedures.

Securities that are traded regularly in the over-the-counter market (other than the NASDAQ/NMS), including securities listed on exchanges but primarily traded over-the-counter, are valued on the basis of bid quotes or the mean between the bid and asked quotes based upon quotes furnished by one or more broker-dealers or market makers for those securities. Securities that may be traded over-the-counter include equity securities, fixed-income securities, non-exchange-listed foreign securities, and certain derivative instruments. Fixed-income securities may be valued using prices provided directly from one or more broker-dealers, market makers, or independent third-party pricing services which may use matrix pricing and valuation models, as well as recent market transactions for the same or similar assets, to derive values when such prices are believed to reflect fair market values of such securities. Such prices may be determined by taking into account securities prices, yields, maturities, call features, ratings, prepayment speeds, credit risks, cash flows, institutional size trading in similar

groups of securities and developments related to specific securities. Fixed-income securities maturing within a relatively short period, less than 60 days, are valued at amortized cost when it approximates fair value.

Foreign equity securities are generally priced at the closing price or last sales price reported on the foreign exchange on which they are principally traded. If there have been no sales for that day on the primary exchange, then the value is determined with reference to the last sale price on any other exchange. If there have been no sales of the security for that day on any exchange, the security will be valued at fair value pursuant to the Trust’s fair value procedures. Spot and forward foreign currency exchange contracts generally are valued using an independent pricing service. The value of assets denominated in foreign currencies is converted into U.S. dollars using exchange rates deemed appropriate by NTI as Investment Adviser. Any use of a different rate from the rates used by the index provider may adversely affect the Fund’s ability to track its Underlying Index. The index provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Exchange-traded financial futures and options thereon are valued at the settlement price as established by the exchange on which they are traded. Over-the-counter options are valued at broker-provided bid prices, as are swaps. The foregoing prices may be obtained from one or more independent pricing services or, as needed or applicable, independent broker-dealers. If there was no sale on that day, and for other non-exchange traded derivatives, the contract is valued at fair value pursuant to the Trust’s fair value procedures.

Each Fund relies on various sources to calculate its NAV. The ability of the Funds’ administrator to calculate the NAV per share of the Funds is subject to operational risks associated with processing or human errors, systems or technology failures, and errors caused by third party service providers, data sources, or trading counterparties. Such failures may result in delays in the calculation of the Funds’ NAVs and/or the inability to calculate NAV over extended time periods. The Funds may be unable to recover any losses

Notes to the Financial Statements (cont.)

associated with such failures, and it may be necessary for alternative procedures to be followed to price portfolio securities when determining the Funds’ NAVs.

Various inputs are used in determining the value of each Fund’s investments. These inputs are summarized in three levels listed below:

• Level 1—Quoted prices in active markets for identical assets on the measurement date.

• Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

• Level 3—Significant unobservable inputs (including the Funds’ own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For example, short-term debt securities may be valued at amortized cost, as long as amortized cost approximates the current fair value of a security, but since the valuation is not obtained from a quoted price in an active market, such securities are reflected as Level 2.

The following is a summary of the valuations as of April 30, 2021 for each Fund based upon the three levels defined above. Please refer to the Schedules of Investments to view equity and debt securities segregated by industry type, where applicable.

Foreign Securities

The FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund (through its investment in its Underlying Funds), FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and the FlexShares International Quality Dividend Dynamic Index Fund invest in publicly-traded equity securities of issuers in countries other than the United States of America (“U.S.”). Such investments include direct investments in non-U.S. dollar denominated securities traded outside the U.S. The Funds’ investments in foreign securities also may be in the form of ADRs and Global Depositary Receipts (“GDRs”) (collectively, “Depositary Receipts”) based on securities in their Underlying Indexes. ADRs are receipts that are traded in the United States evidencing ownership of the underlying foreign securities and are denominated in U.S. dollars. GDRs are receipts issued by a non-U.S. financial institution evidencing ownership of underlying foreign or U.S. securities and usually are denominated in foreign currencies. GDRs may not be denominated in the same currency as the securities they represent. Generally, GDRs are designed for use in foreign securities markets.

In addition to investment risks associated with the underlying issuer, ADRs and GDRs expose a Fund to risk associated with non-uniform terms that apply to ADR and GDR programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency and liquidity risk. ADRs and GDRs are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

To the extent a Fund invests in ADRs, such ADRs will be listed on a national securities exchange. To the extent a Fund

invests in GDRs, such GDRs will be listed on a foreign exchange. A Fund will not invest in any unlisted Depositary Receipt, any Depositary Receipt that NTI deems to be illiquid or any Depositary Receipt for which market quotations are not readily available. Generally, all Depositary Receipts must be sponsored.

The FlexShares Credit-Scored US Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund and the FlexShares High Yield Value-Scored Bond Index Fund may invest in U.S. dollar denominated bonds of non-U.S. corporations to the extent such bonds are included in each Fund’s Underlying Index. The FlexShares Core Select Bond Fund may invest in U.S. dollar denominated bonds of non-U.S. corporations, either directly or indirectly through Underlying Funds, to achieve its investment objective.

The FlexShares Ready Access Variable Income Fund may invest, without limitation, in fixed-income securities and instruments of foreign issuers in developed and emerging markets, including debt securities of foreign governments.

Investing in foreign securities, including Depositary Receipts, may result in a Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in U.S. securities, due to less liquid markets, and adverse economic, political, diplomatic, financial, and regulatory factors. Foreign governments also may impose taxes and limits on investment and repatriation. Any of these events could cause the value of a Fund’s foreign investment to decline. To the extent that a Fund’s assets are significantly invested in a single country or geographic region, a Fund will be subject to the risks associated with that particular country or region.

The FlexShares Emerging Markets Quality Low Volatility Fund and FlexShares Morningstar Emerging Markets Factor Tilt Index Fund will invest primarily in emerging market countries. In addition, the FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund (through its investment in its Underlying Funds), FlexShares International Quality

FLEXSHARES SEMIANNUAL REPORT 351

Notes to the Financial Statements (cont.)

Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and the FlexShares International Quality Dividend Dynamic Index Fund may invest its assets in emerging market countries. The FlexShares Ready Access Variable Income Fund may invest up to 20% of its total assets in fixed-income securities and instruments of issuers in emerging markets. The markets of emerging market countries are less developed and less liquid, subject to greater price volatility and generally subject to increased economic, political, regulatory and other uncertainties than more developed foreign markets. The risks of foreign investment are increased when the issuer is located in a country with an emerging economy or securities market.

Inflation-Indexed Securities

The FlexShares iBoxx 3-Year Target Duration TIPS Index Fund and the FlexShares iBoxx 5-Year Target Duration TIPS Index Fund invest primarily in U.S. Treasury Inflation-Protected Securities (“TIPS”). The FlexShares Ready Access Variable Income Fund and the FlexShares Core Select Bond Fund (directly or through its Underlying Funds) may invest in inflation-indexed securities.

TIPS issued by the U.S. Treasury have varying maturities and pay interest on a semiannual basis equal to a fixed percentage of the inflation-adjusted principal amount. If the periodic adjustment rate measuring inflation falls, the principal value of TIPS will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of TIPS, even during a period of deflation.

The value of TIPS is expected to change in response to changes in real interest rates. Real interest rates in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if the rate of inflation rises at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of TIPS. In contrast, if nominal interest rates increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of TIPS. Any increase in the principal

amount of TIPS will be considered taxable ordinary income, even though investors do not receive their principal until maturity.

While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation, investors in these securities may not be protected to the extent that the increase is not reflected in the TIPS’ inflation measure.

The periodic adjustment of TIPS is tied to the Consumer Price Index for Urban Consumers (“CPI-U”), which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. There can be no assurance that the CPI-U will accurately measure the real rate of inflation in the prices of goods and services.

Mortgage-Backed Pass-Through Securities

The FlexShares Disciplined Duration MBS Index Fund invests primarily in U.S. agency mortgage-backed pass-through securities (“MBS”), a category of pass-through securities backed by pools of mortgages and issued by one of the following U.S. government agencies: the Federal National Mortgage Association (FNMA or Fannie Mae), the Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac) or the Government National Mortgage Association (GNMA or Ginnie Mae) (each a “US Agency”). Under normal circumstances, the Fund will invest at least 80% of its total assets in the securities of its Underlying Index and in “to-be announced transactions” (“TBA transactions”) that represent securities in its Underlying Index. In a TBA transaction, the buyer and seller agree upon general trade parameters such as agency, coupon rate, settlement date, par amount and price. The actual pools delivered generally are determined two days prior to settlement.

Pending settlement of such TBA contracts, the FlexShares Disciplined Duration MBS Index Fund will invest in liquid, short-term instruments. The FlexShares Core Select Bond Fund may also invest either directly or through its Underlying Funds in MBS, including TBA transactions.

Notes to the Financial Statements (cont.)

Mortgage Dollar Rolls

The FlexShares Disciplined Duration MBS Index Fund and the FlexShares Core Select Bond Fund (directly or through its Underlying Funds) may enter into mortgage dollar roll transactions. A mortgage dollar roll involves the sale by the Fund of securities for delivery in the future (generally within 30 days). The Fund simultaneously contracts with the same counterparty to repurchase substantially similar (same type, coupon and maturity) but not identical securities on a specified future date. During the roll period, the Fund will not be entitled to accrue interest and receive principal payments on the securities sold. However, the Fund benefits to the extent of any difference between (a) the price received for the securities sold and (b) the lower forward price for the future purchase and/or fee income plus the interest earned on the cash proceeds of the securities sold. Successful use of mortgage dollar rolls depends upon the Investment Adviser’s ability to predict correctly interest rates and mortgage prepayments. The use of this technique may diminish the investment performance of the Fund compared with what such performance would have been without the use of mortgage dollar rolls.

For financial reporting and tax purposes, a Fund treats mortgage dollar rolls as two separate transactions: one involving the purchase of a security and a separate transaction involving a sale. The Fund currently does not intend to enter into mortgage dollar rolls that are accounted for as financing and does not treat them as borrowings.

Repurchase Agreements

To the extent consistent with its investment policies, each Fund may enter into repurchase agreements under which it purchases securities (collateral) for cash from a seller and agrees to resell those securities to the same seller within a specified time at a specified price. During the term of a repurchase agreement, the market value of the underlying collateral, including accrued interest, is required to equal or exceed the market value of the repurchase agreement. The underlying collateral for tri-party repurchase agreements is held in accounts at JPMorgan Chase, the Fund’s custodian, and is not reflected in the assets of the Funds, at the Bank of New York or JPMorgan Chase which, in turn, holds

securities through the book-entry system at the Federal Reserve Bank of New York. The Fund is subject to credit risk on repurchase agreements to the extent that the counterparty fails to perform under the agreement and the value of the collateral received falls below the agreed repurchase price.

The Northern Trust Company, the parent of NTI, currently is a party to various Master Repurchase Agreements with a number of different counterparties, and acts as agent on behalf of various disclosed principals, including the Funds and various other accounts managed by NTI, in entering into repurchase agreements under the Master Repurchase Agreements. NTI administers and manages these repurchase agreements in accordance with and as part of its duties under its investment advisory agreement with the Funds and does not collect any additional fees from the Funds for such services. As of April 30, 2021, none of the Funds presented in these financial statements had repurchase agreements outstanding except as discussed below.

As of April 30, 2021, the FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares STOXX^® US ESG Select Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, and the FlexShares iBoxx 5-Year Target Duration TIPS Index Fund invested cash collateral for loans of portfolio securities in repurchase agreements, as reflected in the respective Schedule of Investments under the caption “Securities Lending Reinvestments.”

FLEXSHARES SEMIANNUAL REPORT 353

Notes to the Financial Statements (cont.)

Securities Lending

Each Fund may lend securities to banks, brokers and dealers or other qualified institutions. In exchange, the Fund is required to receive minimum initial collateral value as follows:

Type of Loan	Minimum Initial Collateral Requirement
U.S. dollar denominated securities secured by U.S. dollar denominated government securities or cash collateral		102	%
U.S. dollar denominated securities secured by non-U.S. dollar denominated government securities or cash collateral		105	%
Non-U.S. dollar denominated securities secured by government securities or cash collateral in the same denomination as the lent securities		102	%
Non-U.S. dollar denominated securities secured by government securities or cash collateral in the different denomination from the lent securities		105	%
U.S. dollar and Non-U.S. dollar denominated securities secured by equity securities collateral		105	%

The collateral is maintained thereafter, at a value equal to at least 100% of the value of the securities loaned. The collateral amount is valued at the beginning of each business day and is compared to the market value of the loaned securities from the prior business day to determine if additional collateral is required. If additional collateral is required, a request is sent to the borrower.

Securities lending may represent no more than one-third of the value of a Fund’s total assets (including the loan collateral). JPMorgan Chase Bank, N.A. (the “Securities Lending Agent”) serves as the securities lending agent for the securities lending program of a Fund.

Collateral for loans of portfolio securities made by a Fund may consist of cash, cash equivalents, securities issued or guaranteed by the U.S. government or foreign governments or its agencies (or any combination thereof). Any cash collateral received by the Fund in connection with these loans may be invested in a variety of short-term investments, either

directly or indirectly through money market portfolios. The market value of securities on loan and the value of investments made with cash collateral received are disclosed in the Schedules of Investments. Securities lending income includes income from the securities lending program recorded when earned from the Securities Lending Agent and any fees charged to borrowers less expenses associated with the loan. The net amount is reflected in the Statement of Operations under “Securities lending income (net of fees).” The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day.

When a Fund lends its securities, it will continue to receive payments equal to the dividends and interest paid on the securities loaned and simultaneously may earn interest on the investment of the cash collateral.

A Fund will have the right to terminate a loan at any time and recall the loaned securities within the normal and customary settlement time for securities transactions. A Fund does not have the right to vote securities on loan, but can terminate the loan and regain the right to vote if a material event affecting the securities occurred. A borrower might become insolvent or refuse to honor its obligation to return the securities. In the event of a default by a borrower with respect to any loan, the Securities Lending Agent will exercise any and all remedies provided under the applicable borrower agreement. These remedies include purchasing replacement securities for the Fund by applying the collateral held from the defaulting borrower against the purchase cost of the replacement securities. If the proceeds from the collateral are less than the purchase cost of the replacement securities, the Securities Lending Agent is responsible for such shortfall, subject to certain limitations that are set forth in detail in the Securities Lending Agency Agreement. In this event, a Fund could experience delays in recovering its securities and possibly may incur a capital loss. Each Fund will be responsible for any loss that might result from its investment of the cash collateral it receives from a borrower.

FlexShares iBoxx 5-Year Target Duration TIPS Index Fund		3,648,356

At April 30, 2021, the Securities Lending Agency Agreement does not permit the Funds to enforce a netting arrangement.

The cash collateral received from securities loaned as disclosed in the Statements of Assets and Liabilities is

collateralized by securities on loan as disclosed within the Schedules of Investments and such borrowings have maturities that are overnight and continuous.

Securities lending agreements may be subject to regulation as qualified financial contracts (“QFCs”). Regulations adopted by federal banking regulators under the Dodd-Frank Act, which took effect in 2019, require that certain QFCs with counterparties that are part of U.S. or foreign global systemically important banking organizations be amended to include contractual restrictions on close-out and cross-default rights. If a covered counterparty of a Fund or certain of the covered counterparty’s affiliates were to become subject to certain insolvency proceedings, the Fund may be temporarily unable to exercise certain default rights, and the QFC may be transferred to another entity. These requirements may impact a Fund’s credit and counterparty risks.

Derivative Contracts

Futures Contracts

All of the Index Funds may invest in futures contracts to help track the price and yield performance of their Underlying Indexes. At the time a Fund enters into a futures contract, it is generally required to make a margin deposit with the custodian of a specified amount of liquid assets. Subsequent payments to be made or received by the Funds equal to the change in contract value are recorded as variation margin payable or receivable and offset in unrealized gains or losses. Futures are marked to market each day with the change in value reflected in the unrealized gains or losses. A Fund recognizes a realized gain or loss when a contract is closed or expires. The Statements of Operations reflect unrealized gains or losses on open futures contracts, as “Net change in unrealized appreciation (depreciation) on futures contracts”, and any realized gains (losses) on closed futures contracts as “Net realized gain (loss) from Expiration or closing of futures contracts”.

The FlexShares Core Select Bond Fund may take long or short positions in futures to manage the Fund’s exposure to interest rate risk. When applicable, the Fund seeks to mitigate the potential impact of interest rates on the performance of bonds by entering into short positions in U.S.

FLEXSHARES SEMIANNUAL REPORT 355

Notes to the Financial Statements (cont.)

Treasury futures or transactions in interest rate swaps. The Fund’s short positions in U.S. Treasury futures and interest rate swaps are not intended to mitigate credit spread risk or other factors influencing the price of bonds, which may have a greater impact than interest rates. In addition, when interest rates fall, long-only bond investments will perform better than the Fund’s investments. As of April 30, 2021, the FlexShares Core Select Bond Fund did not hold swaps.

As of April 30, 2021, the FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares STOXX^® US ESG Select Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and the FlexShares International Quality Dividend Dynamic Index Fund had open futures contracts.

The use of futures contracts involves, to varying degrees, elements of market and counterparty risk, which may exceed the amounts recognized in the Statements of Assets and Liabilities. Futures contracts present the following risks: imperfect correlation between the change in market value of a Fund’s securities and the price of futures contracts; the possible inability to close a futures contract when desired; losses due to unanticipated market movements, which potentially are unlimited; and the possible inability of NTI to correctly predict the direction of securities prices, interest rates, currency exchange rates and other economic factors. Futures markets are highly volatile and the use of futures may increase the volatility of a Fund’s NAV. As a result of the low margin deposits normally required in futures

trading, a relatively small price movement in a futures contract may result in substantial losses to a Fund. Futures contracts may be illiquid, and exchanges may limit fluctuations in futures contract prices during a single day. Foreign exchanges or boards of trade generally do not offer the same protection as U.S. exchanges.

Foreign Currency Translations

Values of investments denominated in foreign currencies are converted into U.S. dollars using the prevailing market rates on the date of valuation as quoted by one or more banks or dealers that make a two-way market in such currencies (or a data service provider based on quotations received from such banks or dealers). Any use of a rate different from the rates used by an Index Fund’s index provider may affect a Fund’s ability to track its Underlying Index. The cost of purchases and proceeds from sales of investments, interest and dividend income are translated into U.S. dollars using the spot market rate of exchange prevailing on the respective dates of such transactions. “Net realized gain (loss) on foreign currency transactions” on the Statements of Operations include the effect of changes in exchange rates between trade date and settlement date on investment security transactions, foreign currency transactions and interest and dividends received, and the portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial purchase trade date and subsequent sale trade date is included in “Net realized gain (loss) on investment in securities” on the Statements of Operations. Unrealized gains and losses on assets and liabilities, other than investments in securities, which result from changes in foreign currency exchange rates have been included in “Net change in unrealized appreciation (depreciation) on translation of other assets and liabilities denominated in foreign currencies” on the Statements of Operations.

Forward Foreign Currency Exchange Contracts

The FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund,

Notes to the Financial Statements (cont.)

FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, and the FlexShares Ready Access Variable Income Fund may enter into forward foreign currency exchange contracts to facilitate local settlements or to protect against currency exposure in connection with its distributions to shareholders. The Index Funds, however, do not expect to engage in currency transactions for speculative purposes (e.g., for potential income or capital gain). The FlexShares Ready Access Variable Income Fund also may engage in forward foreign currency transactions for hedging purposes in order to protect against uncertainty in the level of future foreign currency exchange rates. The Fund, however, does not expect to engage in currency transactions for speculative purposes. All forward foreign currency exchange contracts held are “marked-to-market” daily at the applicable exchange rates and any resulting unrealized gains or losses are recorded. The Funds record realized gains or losses at the time the forward foreign currency exchange contract is offset by entering into a closing transaction or extinguished by delivery of the currency. The difference between the future foreign currency exchange rates at the date of entry into the contract and the rates at the reporting date are included in “Net change in unrealized appreciation (depreciation) on forward foreign currency contracts” in the Statements of Operations. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. Dollars without the delivery of foreign currency.

There are several risks associated with these contracts. One risk is the potential inability of counterparties to meet the terms of their contracts, and unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The contractual amounts of forward foreign currency exchange contracts do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. The Statements of Operations reflect (i) realized gains or losses, if any, in “Net realized gain (loss) from settlement of forward foreign currency contracts” and (ii) unrealized gains or

losses in “Net change in unrealized appreciation (depreciation) on forward foreign currency contracts”. Forward foreign currency exchange contracts are privately negotiated transactions and can have substantial price volatility. As a result, they offer less protection against default by the other party than is available for instruments traded on an exchange. The institutions that deal in forward foreign currency exchange contracts are not required to continue to make markets in the currencies they trade, and these markets can experience periods of illiquidity.

As of April 30, 2021, the FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares STOXX Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and the FlexShares International Quality Dividend Dynamic Index Fund had open forward foreign currency contracts.

Offsetting of Financial Assets and Derivative Assets

The Funds’ accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the International Swaps and Derivatives Association (ISDA) Master Agreement or similar agreement does not result in an offset of reported amounts of financial assets and financial liabilities in the Statements of Assets and Liabilities across transactions between the Fund and the applicable counterparty. In the event of a default, the agreement provides the right for the non-defaulting party to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. The Funds’ right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which a specific master netting agreement counterparty is subject.

Taxes and Distributions

Each Fund has qualified and intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net capital gains to shareholders. Accordingly, no provision for federal and state income taxes is required in the financial statements.

As of October 31, 2020, management of the Funds has reviewed all open tax years and major jurisdictions and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next 12 months. On an ongoing basis management will monitor the tax positions taken to determine if adjustment to conclusions are necessary based on factors including but not limited to further implementation on guidance expected from FASB and on-going analysis of tax law, regulation, and interpretations thereof.

3. Investment Transactions and Related Income and Expense

Throughout the reporting period, investment transactions are accounted for no later than one business day following

the trade date. For financial reporting purposes, investment transactions are accounted for on the trade date on the last business day of the reporting period.

Interest income is recognized on an accrual basis. Bond discount is accreted and premium is amortized using the effective yield method. Dividend income is recorded on the ex-dividend date, or as soon as information is available. Gains or losses realized on sales of securities are determined using the specific identification method by comparing the identified cost of the security lot sold with the net sales proceeds.

Each Fund except the FlexShares iBoxx 3-Year Target Duration TIPs Index Fund, FlexShares iBoxx 5-Year Target Duration TIPs Index Fund and the FlexShares High Yield Value-Scored Bond Index Fund may hold the securities of real estate investment trusts (“REITs”). Distributions from such investments may be comprised of return of capital, capital gains and income. The actual character of amounts received during the year is not known until after the REIT’s fiscal year end. The Fund records the character of distributions received from REITs during the year based on estimates available. The characterization of distributions received by the Fund may be subsequently revised based on information received from the REITs after their tax reporting periods concluded.

All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the

FLEXSHARES SEMIANNUAL REPORT 369

Notes to the Financial Statements (cont.)

foreign markets in which a Fund invests. These foreign taxes, if any, are paid by the Funds and disclosed in the Statements of Operations. Foreign taxes payable, if any, are reflected in the Funds’ Statements of Assets and Liabilities.

Expenses directly attributable to a Fund are charged to that Fund, while expenses which are attributable to more than one Fund are allocated among the respective Funds based upon relative net assets or another reasonable basis.

4. Investment Advisory Fees

NTI serves as the Investment Adviser of the Funds pursuant to the Investment Advisory Agreement. The Investment Adviser is responsible for making investment decisions for the Funds and for placing purchase and sale orders for portfolio securities, subject to the general supervision of the Board.

As compensation for its advisory services and assumption of certain Fund expenses, NTI is entitled to a unitary management fee (“Management Fee”), computed daily and payable monthly, at the annual rates set forth in the table below (expressed as a percentage of each Fund’s respective average daily net assets).

From the Management Fee, NTI pays most of the expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services (“Covered Expenses”). Covered Expenses do not include the following fees under the Investment Advisory Agreement: interest expenses, brokerage commissions and other trading expenses, fees and expenses of the independent trustees and their independent legal counsel, taxes and other extraordinary costs such as litigation and other expenses not incurred in the ordinary course of business.

The Management Fee rate payable by each Fund is set forth in the following table:

Fund	Unitary Management Fee
FlexShares US Quality Low Volatility Index Fund		0.22	%

Effective March 1, 2021, the Investment Adviser has contractually agreed until March 1, 2022, to reimburse a portion of the operating expenses of each Fund (other than acquired fund fees and expenses (“AFFE”)) so the “Total Annual Fund Operating Expenses After Expense Reimbursement” do not exceed the Fund’s Management Fee plus (+) .0049%. In the case of the FlexShares Real Assets Allocation Index Fund, the Investment Adviser has contractually agreed until March 1, 2022 to waive Management Fees or reimburse certain expenses in an amount equal to the AFFE attributable to the Fund’s investments in its Underlying Fund. In the case of the FlexShares Core Select Bond Fund, the Investment Adviser has contractually agreed until March 1, 2022 to waive Management Fees or reimburse certain expenses in an amount equal to the sum of (a) any AFFE incurred by the Fund that are attributable to the Fund’s investment in Underlying Funds managed by NTI or an investment adviser controlling, controlled by, or under common control with NTI (“Affiliated Funds”); and (b) 0.05% or such lesser amount in AFFE incurred by the Fund that are attributable to the Fund’s investment in Underlying Funds that are not Affiliated Funds. AFFE are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies. Because AFFE are not direct expenses of the Fund, they are not reflected on the Fund’s financial statements. After these dates, the Investment Adviser and a Fund may mutually agree to extend the contractual arrangements. The Board may terminate the contractual arrangements at any time if it determines that it is in the best interest of a Fund and its shareholders. These expenses and the reimbursements are shown as “Investment advisory fees reimbursed” on the Statements of Operations.

In addition, effective October 29, 2018, NTI contractually agreed to reimburse the Funds for certain other fees and expenses that are not Covered Expenses. These fees and expenses and the reimbursements are shown as Other expenses and Other expenses reimbursed, respectively, in the Statements of Operations.

The Investment Adviser may voluntarily waive or reimburse additional management fees. Amounts waived or reimbursed by the Investment Adviser may not be recouped by the Investment Adviser. These waivers and/or reimbursements are shown as Expenses waived and/or reimbursed by Advisor on the Statements of Operations. During the six months ended April 30, 2021, the Investment Adviser did not voluntarily waive or reimburse additional management fees.

5. Administration Fees

JPMorgan Chase Bank, N.A. (the “Administrator”) serves as administrator of the Funds. The Administrator provides certain administrative services to the Funds. For these services, the Administrator is entitled to certain fees and reasonable out-of-pocket expenses. These fees and expenses are Covered Expenses as defined above.

6. Custodian Fees

JPMorgan Chase Bank, N.A. (the “Custodian”) acts as custodian for the Funds in accordance with a Global Custody Agreement. The Custodian holds cash, securities and other assets of the Funds as required by the 1940 Act. As compensation for the services rendered under the agreement, the Custodian is entitled to fees and reasonable out-of-pocket expenses. These fees and expenses are Covered Expenses as defined above.

7. Trustees Fees

The Trust compensates each Trustee who is not an officer, director or employee of Northern Trust Corporation, or its subsidiaries, for his or her services as a Trustee of the Trust and as a member of Board committees.

The Trust has adopted a DC Plan for its Trustees who are not officers of Northern Trust or NTI. Under the DC Plan, Independent Trustees may elect to defer all or a portion of

FLEXSHARES SEMIANNUAL REPORT 371

Notes to the Financial Statements (cont.)

their compensation. The amount deferred is adjusted periodically based upon the performance of the investment options selected by the Trustees. The investment options currently available under the DC Plan are the FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares STOXX^® US ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Quality Dividend Index Fund, FlexShares iBoxx 5-Year Target Duration TIPS Index Fund, and the FlexShares Ready Access Variable Income Fund. Expenses related to the DC Plan are stated on the Statements of Operations.

8. Distribution and Service Plan

Foreside Fund Services, LLC (the “Distributor”) serves as the Funds’ distributor and distributes Creation Units (as described in Note 9) for each Fund on an agency basis. The Distributor does not receive a fee from the Funds for its distribution services. However, it receives compensation from NTI for its services as distributor pursuant to a separate letter agreement between it and NTI.

The Trust has adopted a Distribution and Service Plan (“the Plan”) pursuant to Rule 12b-1 under the 1940 Act. Payments to financial intermediaries under the Plan are tied directly to their own out-of-pocket expenses. The Plan has not been implemented with respect to the Funds. The Plan may not be implemented without further Board approval. The maximum distribution fee is 0.25% of each Fund’s respective average daily net assets under the Plan. The Funds did not pay any 12b-1 fees during the fiscal period.

9. Issuance and Redemption of Fund Shares

Each Fund only issues and redeems shares to Authorized Participants in exchange for the deposit or delivery of a basket of assets (securities and/or cash), in large blocks known as Creation Units, each of which is comprised of a specified number of shares.

Retail investors may only purchase and sell fund shares in the secondary market through a broker-dealer and such

transactions may be subject to customary commission and fee rates imposed by the broker-dealer.

Authorized Participants may pay transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The transaction fees are paid directly to the Fund and used to offset Fund custody fees. Certain fees or costs associated with Creation Unit purchases may be paid by NTI in certain circumstances. In addition, the Trust may from time to time waive the standard transaction fee. The net custody fees charged to the Fund are paid for by the Investment Adviser through the Fund’s Unitary Fee. Transaction fees remaining in the Funds were as follows:

12. Guarantees and Indemnifications

In the normal course of business each Fund enters into contracts with third-party service providers that contain a variety of representations and warranties and that provide general indemnifications. Additionally, under the Funds’ organizational documents, the officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. The Funds’ maximum exposure under these arrangements is unknown, as it involves possible future claims that may or may not be made against the Funds.

13. New Accounting Pronouncements

In March 2020, the FASB issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848) “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of the London Interbank Offered Rate (“LIBOR”) and other interbank-offered based reference rates as of the end of 2021. The new guidance is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022, and the adoption of ASU 2020-04 is elective. Management does not believe this update has a material impact on the Funds’ financial statements and disclosures.

14. LIBOR Transition

Certain of the Funds’ investments, payment obligations and financing terms may be based on floating rates, such as LIBOR, Euro Interbank Offered Rate and other similar types of reference rates (each, a “Reference Rate”). On July 27, 2017, the Chief Executive of the UK Financial Conduct Authority (FCA), which regulates LIBOR, announced that the FCA will no longer persuade nor compel banks to submit rates for the calculation of LIBOR and certain other Reference Rates after 2021. The FCA and ICE Benchmark Administrator have since announced that most LIBOR settings will no longer be published after December 31, 2021 and a majority of U.S. dollar LIBOR settings will cease publication after June 30, 2023. The U.S. Federal Reserve, based on the recommendations of the New York Federal Reserve’s

Notes to the Financial Statements (cont.)

Alternative Reference Rate Committee comprised of major derivative market participants and their regulators), has begun publishing SOFR that is intended to replace U.S. dollar LIBOR. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Uncertainty related to the liquidity impact of the change in rates, and how to appropriately adjust these rates at the time of transition, poses risks for the Funds. The effect of any changes to, or discontinuation of, LIBOR on the Funds will depend on, among other things, (1) existing fallback or termination provisions in individual contracts, and (2) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new instruments and contracts. The expected discontinuation of LIBOR could have a significant impact on the financial markets in general and may also present heightened risk to market participants, including public companies, investment advisers, investment companies, and broker-dealers. The risks associated with this discontinuation and transition will be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR on the Funds until new reference rates and fallbacks for both legacy and new instruments and contracts are commercially accepted and market practices become settled. Until then, the Funds may continue to invest in instruments that reference such rates or otherwise use such Reference Rates due to favorable liquidity or pricing.

15. Legal Proceedings

On or about February 14, 2020, Marc S. Kirschner, as Trustee for NWHI Litigation Trust (the “Trust”), and Wilmington Savings Fund Society, FSB, as successor indenture trustee for various notes issued by Nine West Holdings, Inc. (together with the Trustee, “Plaintiffs”), filed separate complaints in the United States District Court for the Northern District of Illinois (case nos. 20-cv-01129 and 20-cv-01136, respectively) against a group of defendants that includes the FlexShares Morningstar US Market Factor Tilt Index Fund in its capacity as a former public shareholder of The Jones Group Inc. (“Jones Group”). The claims in these actions stem from a series of merger transactions (“Transactions”)

entered into by Jones Group in 2014 that allegedly rendered Jones Group insolvent. The FlexShares Morningstar US Market Factor Tilt Index Fund allegedly received $224,910 as a result of the Transactions. The Plaintiffs seek to clawback these proceeds for the benefit of the Trust and the noteholders on the basis that they allegedly were fraudulent conveyances.

During the quarter ended June 30, 2020, the Judicial Panel on Multidistrict Litigation ordered the transfer of these actions and several substantially similar actions filed in other districts to the Southern District of New York for consolidated pre-trial proceedings. On June 29, 2020, the former public shareholder defendants, including FlexShares Morningstar US Market Factor Tilt Index Fund, filed a motion to dismiss on the basis that the payments made to them in connection with the Transactions were shielded from the fraudulent conveyance claims under Section 546(e) of the Bankruptcy Code. On August 27, 2020, all fraudulent conveyance claims against the former public shareholder defendants were dismissed. Plaintiffs appealed from that decision and the actions are currently on appeal before the U.S. Court of Appeals for the Second Circuit.

Since it is presently not possible to determine the outcome of these matters, no provision has been made in the financial statements for their ultimate resolution. In management of the Fund’s opinion, the final resolution of the above legal matters will not have a material adverse effect on the Fund’s financial statements. The Fund intends to vigorously defend these actions.

16. Coronavirus (COVID-19) Pandemic

The outbreak of a respiratory disease caused by a novel coronavirus was first detected in December 2019 and has spread internationally. The outbreak and efforts to contain its spread have resulted in closing borders and quarantines, restricting international and domestic travel, enhanced health screenings, cancellations, disrupted supply chains and customer activity, responses by businesses (including changes to operations and reducing staff), and have produced general concern and uncertainty. The impact of the coronavirus pandemic, and other epidemics and pandemics that may arise in the future could adversely affect national

Notes to the Financial Statements (cont.)

and global economies, individual companies and the market in general in a manner and for a period of time that cannot be foreseen at the present time and may adversely affect the value, volatility and liquidity of securities held by a Fund. In addition, during periods of market disruption or other abnormal market conditions, the Funds’ exposure to the risks described in their respective prospectuses and statements of additional information will likely increase. In the event of a pandemic or an outbreak, there can be no assurance that the Funds and their service providers will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons, and could otherwise disrupt the ability of the Fund’s service providers to perform essential services. Certain economic and market conditions arising out of a pandemic or outbreak could result in a Fund’s inability to achieve its investment objectives, cause the postponement of reconstitution or rebalance dates for benchmark or underlying indices, adversely affect the prices and liquidity of the securities and other instruments in which a Fund invests, negatively impact a Fund’s performance, and cause losses on your investment in a Fund. Management is monitoring the development of the pandemic, which was ongoing as of the date of the financial statements, and is evaluating its impact on the financial position and operating results of the Funds.

17. Subsequent Events

Management has evaluated subsequent events for the Funds through the date the financial statements were issued, and has concluded that there are no recognized or non-recognized subsequent events relevant for financial statement disclosure, other than the items noted below.

Effective June 1, 2021, the name of the FlexShares^® STOXX^® US ESG Impact Index Fund was changed to FlexShares^® STOXX^® US ESG Select Index Fund and the name of the FlexShares^® STOXX^® Global ESG Impact Index Fund was changed to FlexShares^® STOXX^® Global ESG Select Index Fund.

Fund Expenses (Unaudited)

As a shareholder, you incur two types of costs: (1) Transaction costs for purchasing and selling shares and (2) ongoing costs, including advisory and other Fund expenses. The expense examples below are intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other funds.

Actual Expenses

The actual expense examples are based on an investment of $1,000 invested at the beginning of a six month period and held through the period ended April 30, 2021.

The first line under each Fund in the following tables 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 (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 “Expenses Paid During the Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The hypothetical expense examples are based on an investment of $1,000 invested at the beginning of a six month period and held through the period ended April 30, 2021.

The second line under each Fund in 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 Funds 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 transaction costs, such as brokerage commissions on purchases or sales of Fund shares. Therefore, the second line for each Fund in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Liquidity Risk Management Program (Unaudited)

FlexShares Trust (the “Trust”), on behalf of each of its series (each, a “Fund” and, collectively, the “Funds”), has adopted and implemented a liquidity risk management program (the “Program”) as required by rule 22e-4 under the Investment Company Act of 1940, as amended (the “Rule”). The Program seeks to assess, manage and review each Fund’s Liquidity Risk. “Liquidity Risk” is defined as the risk that a Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investors’ interests in the Fund.

The Trust’s Board of Trustees (the “Board”) has appointed Northern Trust Investments, Inc. (“NTI”), the investment adviser to the Funds, as the program administrator for the Program. NTI has delegated oversight of the Program to the Northern Trust Asset Management Credit & Liquidity Risk Committee (the “Committee”).

At a meeting of the Board held during the six-month period ended April 30, 2021, the Board received and reviewed the annual written report of the Committee, on behalf of NTI (the “Report”), concerning the operation of the Program. The Report addressed the operation of the Program and assessed its adequacy and effectiveness of implementation.

The Report summarized the operation of the Program and the information and factors considered by the Committee in reviewing the adequacy and effectiveness of the Program’s implementation with respect to each Fund. Such information and factors included, among other things: (i) the liquidity risk framework used to assess, manage, and periodically review each Fund’s Liquidity Risk and the results of this assessment; (ii) the methodology and inputs used to classify the liquidity of each Fund’s portfolio investments and the Committee’s assessment that each Fund’s strategy is appropriate for an exchange-traded fund structured as an open-end fund; (iii) that each Fund held primarily highly liquid assets (investments that the Fund anticipates can be converted to cash within 3 business days or less in current market conditions without significantly changing their market value); (iv) that none of the Funds required the establishment of a highly liquid investment minimum (as defined in the Rule) and the methodology for that determination; and (v) confirmation that none of the Funds had breached the 15% maximum threshold on illiquid investments (i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven days or less without the sale or disposition significantly changing the market value of the investment) and the procedures for monitoring compliance with the limit. The Report also summarized the changes made to the Program over the course of the year.

The Committee concluded, and reported to the Board, that the Program was being effectively implemented and that the Program was reasonably designed to assess and manage each Fund’s Liquidity Risk.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to your Fund’s prospectus for more information regarding the Fund’s exposure to Liquidity Risk and other risks to which an investment in the Fund may be subject.

Supplemental Information (Unaudited)

Principal Risks

As with any investment, you could lose all or part of your investment in a Fund, and the Fund’s performance could trail that of other investments. In addition to the discussion of the risks of certain of the Funds’ investments included in Note 2, some of the principal risks of investment in the Funds are summarized below. A more complete description of principal risks is included in each Fund’s Prospectus.

The following risks apply to all of the Funds:

Cyber Security and Operational Risk

Cyber security and operational risk is the risk that the Fund and its service providers may experience disruptions that arise from breaches in cyber security, human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund. Failures or breaches of the electronic systems of the Fund, the Investment Adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders.

Derivatives Risk

Changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, rate or index, and the Funds could lose more than the principal amount invested.

Market Trading Risk

Each Fund’s shares are listed on a securities exchange, which presents risks including the potential lack of an active market for Fund shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Funds. Any of these factors may lead to the Funds’ shares trading at a premium or discount to NAV.

Valuation Risk

The sale price the Funds could receive for a security may differ from the Funds’ valuation of the security, particularly for securities that trade in low volume or volatile markets, or that are valued using a fair value methodology.

Authorized Participant Concentration Risk

Only an Authorized Participant may engage in creation or redemption transactions directly with the Funds. The Funds have a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Funds and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be heightened for a Fund if it invests in non-U.S. securities or other securities or instruments that are less widely traded. Such securities or instruments often involve greater settlement and operational issues and capital costs for Authorized Participants.

Market Risk

Market risk is the risk that general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the bond markets, volatility in the equities market or adverse investor sentiment could cause the value of your investment in a Fund to decline. Market disruptions caused by local or regional

FLEXSHARES SEMIANNUAL REPORT 383

Supplemental Information (cont.)

events such as war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions or other events or adverse investor sentiment could have a significant impact on the Fund and its investments and could result in the Fund’s shares trading at increased premiums or discounts to the Fund’s NAV. The outbreak of COVID-19, a respiratory disease caused by a novel coronavirus, has negatively affected the worldwide economy, the financial health of individual companies and the market in significant and unforeseen ways. The future impact of COVID-19 is currently unknown. The effects to public health, business and market conditions resulting from the COVID-19 pandemic may have a significant negative impact on the performance of the Fund’s investments. Market risk also includes the risk that a particular style of investing, such as growth or value, may underperform the market generally. The value of the securities in which a Fund invests may go up or down in response to the prospects of individual issuers and/or general economic conditions. Securities markets may experience great short-term volatility and may fall sharply at times. Different markets may behave differently from each other and a foreign market may move in the opposite direction from the U.S. market. Price changes may be temporary or last for extended periods. You could lose money over short periods due to fluctuation in a Fund’s NAV in response to market movements, and over longer periods during market downturns.

The following risk applies only to the Index Funds:

Tracking Error Risk

Tracking error risk is the risk that an Index Fund’s performance may vary substantially from the performance of the Underlying Index it tracks as a result of imperfect correlation between a Fund’s securities and those of the Underlying Index. Imperfect correlation may result from share purchases and redemptions, expenses, accepting custom baskets, changes in the Underlying Indexes, asset valuations, foreign currency valuations, market impact, corporate actions (such as mergers and spinoffs), legal restrictions (such as tax-related diversification requirements that apply to the Funds but not to the Underlying Index) and timing variances, among other factors.

Calculation Methodology Risk

Each of the Index Funds is subject to Calculation Methodology Risk. This is the risk that the Underlying Index’s calculation methodology or sources of information may not provide an accurate assessment of included issuers or correct valuation of securities, nor is the availability or timeliness of the production of the Index guaranteed.

The following risks apply to each Fund, as disclosed:

Concentration Risk

Each of the Funds, except the FlexShares iBoxx 3-Year Target Duration TIPS Index Fund and FlexShares iBoxx 5-Year Target Duration TIPS Index Fund, is subject to Concentration Risk. To the extent that the investments of these Funds are concentrated in the securities of issuers in a particular region, country, market, industry, sector or asset class, the Funds may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that region, country, market, industry, sector or asset class.

Interest Rate/Maturity Risk

The FlexShares iBoxx 3-Year Target Duration TIPS Index Fund, FlexShares iBoxx 5-Year Target Duration TIPS Index Fund, FlexShares Disciplined Duration MBS Index Fund, FlexShares Credit-Scored US Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund, FlexShares High Yield Value-Scored Bond Index Fund, FlexShares Ready Access Variable Income Fund, and FlexShares Core Select Bond Fund are subject to the risk that the value of the Funds’ fixed-income assets will decline because of rising interest rates. The magnitude of this decline will often be greater for longer-term fixed

Supplemental Information (cont.)

income securities than shorter-term fixed-income securities. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

MLP Risk

The FlexShares STOXX^® Global Broad Infrastructure Index Fund and FlexShares Real Assets Allocation Index Fund (including through its investment in its Underlying Fund(s)) may invest in Master Limited Partnerships (“MLPs”). The FlexShares STOXX^® Global Broad Infrastructure Index Fund may not invest more than 25% of its net assets in MLPs. MLP Risk is the risk that accompanies an investment in MLP units. Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. MLPs may also be sensitive to changes in interest rates and, during periods of interest rate volatility, limited capital markets access and/or low commodities pricing and may not provide attractive returns. The benefit derived from the Fund’s investment in MLPs is largely dependent on the MLPs being treated as partnerships for federal income tax purposes. If any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, the after-tax return to the Fund with respect to its investment in such MLPs would be materially reduced, which could cause a decline in the value of the Fund’s shares. The Fund must include its allocable share of the MLP’s taxable income in its taxable income, whether or not it receives a distribution of cash from the MLP. In such case, the Fund may have to liquidate securities to make required distributions to the Fund’s shareholders.

Non-diversification Risk

The FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares iBoxx 3-Year Target Duration TIPS Index Fund, FlexShares iBoxx 5-Year Target Duration TIPS Index Fund, FlexShares Credit-Scored US Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund, FlexShares Ready Access Variable Income Fund, FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, and FlexShares Emerging Markets Quality Low Volatility Index Fund are non-diversified series of the Trust, pursuant to the 1940 Act. The performance of these Funds may depend on the performance of a small number of issuers because the Funds may invest a large percentage of its assets in securities issued by or representing a small number of issuers.

Large Cap Risk

The FlexShares US Quality Large Cap Index Fund, FlexShares STOXX^® US ESG Select Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, and FlexShares Emerging Markets Quality Low Volatility Index Fund are subject to the risk that returns on investments in stocks of large U.S. companies could trail the returns on investments in stocks of smaller and mid-sized companies. In addition, larger companies may grow more slowly or be slower to respond to business developments than smaller companies.

Mid Cap Stock Risk

The FlexShares STOXX^® US ESG Select Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, and FlexShares Emerging

FLEXSHARES SEMIANNUAL REPORT 385

Supplemental Information (cont.)

Markets Quality Low Volatility Index Fund may invest in stocks of mid-sized companies which may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market.

Mid and Small Cap Stock Risk

The FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund (including through its investment in its Underlying Fund(s)), FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and FlexShares International Quality Dividend Dynamic Index Fund may invest in stocks of smaller companies which may be more volatile than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally the smaller the company size, the greater the risk.

Value Investing Risk

The FlexSharesMorningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares Global Quality Real Estate Index Fund, and FlexShares Real Assets Allocation Index Fund’s (including through its investment in its Underlying Fund(s)) investment in companies whose securities are believed to be undervalued, relative to their underlying profitability, may not appreciate in value as anticipated.

ESG Investment Risk

The FlexShares STOXX^® US ESG Select Index Fund and FlexShares STOXX^® Global ESG Select Index Fund are subject to the risk that because the methodology of the Underlying Index selects and assigns weights to securities of issuers for nonfinancial reasons, the Fund may underperform the broader equity market or other funds that do not utilize ESG criteria when selecting investments.

High Portfolio Turnover Risk

The FlexShares STOXX^® US ESG Select Index Fund, FlexShares Ready Access Variable Income Fund, FlexShares Core Select Bond Fund, FlexShares iBoxx 3-Year Target Duration TIPS Index Fund, FlexShares Disciplined Duration MBS Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund, and FlexShares High Yield Value-Scored Bond Index Fund are subject to the risk that active and frequent trading of the Fund’s portfolio securities may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other transaction costs, which could reduce the Fund’s return.

Global Natural Resources Risk

The FlexShares Morningstar Global Upstream Natural Resources Index Fund (which is also an Underlying Fund of FlexShares Real Assets Allocation Index Fund) is subject to the risks associated with investment in the global natural resources sector in addition to the general risk of the stock market. The natural resources sector can significantly be affected by events relating to U.S. and foreign political and economic developments and environmental and other government regulations, as well as other factors including, but not limited to: commodity price volatility, technological developments and natural or man-made disasters. Declines in the demand for, or prices of, natural resources generally would be expected to contribute to declines in the

386 FLEXSHARES SEMIANNUAL REPORT

Supplemental Information (cont.)

value of the Fund’s equity securities. Such declines may occur quickly and without warning and may negatively impact the value of the Fund and your investment.

Hedging Risk

The FlexShares Core Select Bond Fund is subject to the risk that the Fund’s short positions in U.S. Treasury futures and transactions in interest rate swaps will not completely eliminate interest rate risk of long positions in bonds. In certain falling interest rate environments, the Fund’s hedging strategy could result in disproportionately larger losses in the short U.S. Treasury futures and interest rate swaps positions as compared to gains in the long bond positions attributable to interest rate changes.

Corporate Bond Risk

The FlexShares Credit-Scored US Corporate Bond Index Fund and FlexShares Credit-Scored US Long Corporate Bond Index Fund invest primarily in bonds issued by corporations. Corporate debt securities are subject to the risk of the issuer’s inability to meet principal and interest payments on the obligation and may also be subject to price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the issuer and general market liquidity. When interest rates rise, the value of corporate debt can be expected to decline. Debt securities with longer maturities tend to be more sensitive to interest rate movements than those with shorter maturities.

Interest Rate Risk

The FlexShares STOXX^® Global Broad Infrastructure Index Fund and FlexShares Global Quality Real Estate Index Fund (which is also an Underlying Fund of FlexShares Real Assets Allocation Index Fund) are subject to the risk that rising interest rates may adversely affect the Fund. Increases in interest rates typically lower the present value of a REIT’s future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors’ collective perceptions of future earnings, the value of the Fund may decline when investors anticipate or experience rising interest rates.

Cash Transactions Risk

The FlexShares Disciplined Duration MBS Index Fund and FlexShares Ready Access Variable Income Fund may effect a creation or redemption order of its shares entirely for cash, rather than for in-kind securities. Paying redemption proceeds entirely in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause a Fund to sell a security or other financial instrument and recognize a capital gain or loss that might not have been incurred if it had not effected a redemption order entirely for cash. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that meet redemption orders entirely in-kind with portfolio securities. The use of all cash creations and redemption orders may also cause a Fund’s shares to trade in the secondary market at wider bid-ask spreads and/or greater premiums or discounts to the Fund’s NAV. To the extent that the maximum additional variable charge for cash creation or cash redemption transactions is insufficient to cover the transaction costs of purchasing or selling portfolio securities, the Fund’s performance could be negatively impacted.

China Investment Risk

The FlexShares Emerging Markets Quality Low Volatility Index Fund, and FlexShares Morningstar Emerging Markets Factor Tilt Index Fund expects to have significant investment in securities of Chinese issuers. Investment exposure to China subjects a Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed

FLEXSHARES SEMIANNUAL REPORT 387

Supplemental Information (cont.)

markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. The Chinese economy is export-driven and highly reliant on trade. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners, such as the United States, Japan and South Korea, may have an adverse impact on the Chinese economy.

Currency Risk

The FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX ^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares Ready Access Variable Income Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, and FlexShares Emerging Markets Quality Low Volatility Index Fund may invest in securities denominated in foreign currencies. While each Fund’s investments may be denominated in foreign currencies, the portfolio securities and other assets held by each Fund are valued in U.S. dollars. Price fluctuations may occur in the dollar value of foreign securities because of changing currency exchange rates. Currency exchange rates may fluctuate significantly over short periods of time causing a Fund’s NAV to fluctuate as well. Currency exchange rates can be affected unpredictably by the intervention or the failure to intervene by U.S. or foreign governments or central banks, or by currency controls or political developments in the U.S. or abroad. To the extent that a Fund’s total assets, adjusted to reflect the Fund’s net position after giving effect to currency transactions, are denominated in the currencies of foreign countries, that Fund will be more susceptible to the risk of adverse economic and political developments within those countries.

Foreign Securities Risk

The FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares STOXX^® Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^® Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, and FlexShares Ready Access Variable Income Fund will invest in foreign securities. Foreign securities include direct investments in non-U.S. dollar-denominated securities traded primarily outside of the United States and dollar-denominated securities of foreign issuers. Foreign securities also include indirect investments such as American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs are U.S. dollar-denominated receipts representing shares of foreign-based corporations. ADRs are receipts that are traded in the U.S., and entitle the holder to all dividend and capital gain distributions that are paid out on the underlying foreign shares. GDRs are receipts that often trade on foreign exchanges. They represent ownership in an underlying foreign or U.S. security and generally are denominated in a foreign currency.

Emerging Markets Risk

The FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX^®Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, and FlexShares Ready Access Variable Income Fund invest in emerging market countries. The risks of foreign investment are increased when the issuer is located in a country with an emerging economy or securities market. Political and economic structures in many of these countries may be undergoing significant evolution and rapid development, and these countries may lack the social, political and economic stability characteristics of developed countries. The securities laws of emerging market countries may be relatively new and unsettled and, consequently, there is a risk of rapid and unpredictable change in laws regarding foreign investment, securities regulation, title to securities and shareholder rights. Global factors and foreign actions may inhibit the flow of foreign capital on which a country is dependent to sustain its growth. In general, securities markets of emerging countries are less liquid, are especially subject to greater price volatility, have smaller market capitalizations, and have problems with securities registration and custody. These securities markets also have less government regulation and are not subject to as extensive and frequent accounting, financial and other reporting requirements as the securities markets of more developed countries. In addition, because the securities settlement procedures are less developed in these countries, a Fund may be required to deliver securities before receiving payment and also may be unable to complete transactions during market disruptions. As a result of these and other risks, investments in these countries generally present a greater risk of loss to a Fund.

Japan Investment Risk

The FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, and FlexShares Developed Markets ex-US Quality Low Volatility Index Fund expects to have significant investment in securities of Japanese issuers. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could negatively impact Japanese issuers. In recent times, Japan’s economic growth rate has remained low, and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, which could negatively affect a Fund. The growth of Japan’s economy has historically lagged that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. Japan’s relations with its neighbors, particularly China, North Korea, South Korea and Russia, have at times been strained due to territorial disputes, historical animosities and defense concerns. Most recently, the Japanese government has shown concern over the increased nuclear and military activity by North Korea. Strained relations may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy in times of crisis. China has become an important trading partner with Japan, yet the countries’ political relationship has become strained. Should political tension increase, it could adversely affect the economy, especially the export sector, and destabilize the region as a whole.

U.S. Issuer Risk

The FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares STOXX US ESG Select Index Fund, FlexShares STOXX Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares Disciplined Duration MBS Index Fund, FlexShares Credit-Scored U.S. Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund,

Supplemental Information (cont.)

FlexShares High Yield Value-Scored Bond Index Fund, FlexShares US Quality Low Volatility Index Fund, FlexShares Ready Access Variable Income Fund, and FlexShares Core Select Bond Fund has significant exposure to U.S. issuers. Decreasing imports or exports, changes in trade regulations and/or an economic recession in the United States may have a material adverse effect on the U.S. economy. The financial crisis that began in 2007 caused a significant decline in the value and liquidity of issuers in the United States. Policy and legislative changes in the United States are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as the value of certain securities. In addition, a continued rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Funds have exposure.

The following risks apply to the FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and FlexShares International Quality Dividend Dynamic Index Fund:

Dividend Risk

The Fund is subject to the risk that an issuer of stock held by a Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks. A Fund’s performance during a broad market advance could suffer because dividend paying stocks may not experience the same capital appreciation as non-dividend paying stocks.

Volatility Risk

The Fund is subject to the risk that the actual level of volatility experienced by a Fund may be greater or lower than the targeted overall volatility of the Fund’s Underlying Index. Although a Fund’s Underlying Index is designed to have a targeted overall volatility, there is no guarantee that it will have the targeted overall volatility. A Fund will continue to seek to track the Underlying Index even if the Underlying Index does not have the targeted overall volatility. There is also the risk that a Fund may experience volatility greater or lower than that of the Underlying Index as a result of tracking error. A portfolio of securities with greater volatility is generally considered to have a higher risk profile than a portfolio with lower volatility.

The following risk applies to the FlexShares Global Quality Real Estate Index Fund (which is also an Underlying Fund of the FlexShares Real Assets Allocation Index Fund):

Real Estate Securities Risk

The Fund is subject to the risks associated with investment in the real estate sector in addition to the general risk of the stock market. Investing in securities of real estate companies will make the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general, as well as risks that relate specifically to the way in which real estate companies are organized and operated. Real estate companies may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. The value of real estate securities may underperform other sectors of the economy or broader equity markets. To the extent that the Fund concentrates its investments in the real estate sector, it may be subject to greater risk of loss than if it were diversified across different industry sectors.

The following risk applies to the FlexShares Global Quality Real Estate Index Fund (which is also an Underlying Fund of FlexShares Real Assets Allocation Index Fund) and FlexShares STOXX^® Global Broad Infrastructure Index Fund:

390 FLEXSHARES SEMIANNUAL REPORT

Real Estate Investment Trust (REIT) Risk

The Fund is subject to the risk that the Fund’s investments will be affected by factors affecting REITs and the real estate sector generally. Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. REITs whose underlying properties are concentrated in a particular industry or geographic region are also subject to risks affecting such industries and regions. By investing in REITs through the Fund, a shareholder will bear expenses of the REITs in addition to expenses of the Fund.

The following risk apply to the FlexShares Real Assets Allocation Index Fund:

Fund of Funds Risk (or Underlying Funds Risk)

The Fund is subject to the risk that the Fund’s investment performance largely depends on the investment performance of the Underlying Fund(s) in which it primarily invests. The Fund’s NAV will change with changes in the value of the Underlying Fund(s) and other securities in which the Fund invests based on their market valuations.

An investment in the Fund will entail more costs and expenses than direct investments in the Underlying Fund(s). The Fund will indirectly pay a proportional share of the expenses of the Underlying Fund(s) in which it invests (including operating expenses and management fees), in addition to the fees and expenses it pays directly. As the Fund’s allocation to an Underlying Fund changes from time to time, or to the extent that the expense ratio of an Underlying Fund changes, the weighted average operating expenses borne by the Fund may increase or decrease.

The following risks apply to the FlexShares Disciplined Duration MBS Index Fund, FlexShares Credit-Scored US Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund, FlexShares High Yield Value-Scored Bond Index Fund, FlexShares Ready Access Variable Income Fund, and FlexShares Core Select Bond Fund:

Credit (or Default) Risk

The Fund is subject to the risk that the inability or unwillingness of an issuer or guarantor of a fixed-income security, or a counterparty to a TBA, repurchase or other transaction, to meet its payment or other financial obligations will adversely affect the value of the Fund’s investments and its returns. The credit quality of a debt security or of the issuer of a debt security held by the Fund could deteriorate rapidly, which may impair the Fund’s liquidity or cause a deterioration in the Fund’s NAV. The Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty. The degree of credit risk depends on the issuer’s or counterparty’s financial condition and on the terms of the securities.

Debt Extension Risk

The Fund is subject to the risk that an issuer will exercise its right to pay principal on an obligation held by the Fund (such as a mortgage-backed security) later than expected. This may happen during a period of rising interest rates. Under these circumstances, the value of the obligation will decrease and the Fund will suffer from the inability to invest in higher yielding securities.

Liquidity Risk

The Fund is subject to the risk that certain portfolio securities may be less liquid than others, which may make them difficult or impossible to sell at the time and the price that the Fund would like, adversely affecting the value of the Fund’s investments and its returns.

FLEXSHARES SEMIANNUAL REPORT 391

Supplemental Information (cont.)

Prepayment (or Call) Risk

The Fund is subject to the risk that prepayment of the underlying mortgages or other collateral of some fixed-income securities may result in a decreased rate of return and a decline in value of those securities.

U.S. Government Securities Risk

The FlexShares Disciplined Duration MBS Index Fund, FlexShares Ready Access Variable Income Fund and FlexShares Core Select Bond Fund are subject to the risk that the U.S. government will not provide financial support to its agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. Many U.S. government securities that may be purchased by the Fund are not backed by the full faith and credit of the United States. It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future.

Mortgage-Related and Other Asset-Backed Risks

The FlexShares Ready Access Variable Income Fund and FlexShares Core Select Bond Fund is subject to the risks of investing in mortgage-related and other asset-backed securities, including Interest Rate/Maturity Risk, Debt Extension Risk and Prepayment (or Call) Risk.

The following risk applies to the FlexShares Disciplined Duration MBS Index Fund:

Mortgage Backed Pass-Through Securities Risk

The Fund is subject to the risk of investing in mortgage-backed securities issued by a U.S. Agency. These securities may not be backed by the full faith and credit of the U.S. government. Mortgage-backed securities are subject to Credit (or Default) Risk, Interest Rate/ Maturity Risk, Debt Extension Risk and Prepayment (or Call) Risk. Because of these risks, mortgage-backed securities react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.

The following risks apply to the FlexShares High Yield Value-Scored Bond Index Fund:

Distressed Securities Risk

Distressed securities risk is the substantial risk of investing in distressed securities that is in addition to the risks of investing in non-investment grade securities generally. NTI defines securities issued by companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations or financial restructurings as “distressed securities.” Distressed securities are speculative and involve a substantial risk that principal will not be paid. In addition, the Fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. These securities may present a substantial risk of default. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

High Yield Securities Risk

High yield securities risk is the risk that the Fund will be subject to greater credit risk, price volatility and risk of loss than if it invested primarily in investment grade securities, which can adversely impact the Fund’s return and net asset value. High yield securities are considered highly speculative and are subject to increased risk of an issuer’s inability to make principal and

interest payments. The Fund’s Underlying Index is designed to be comprised of securities with the potential for higher yields as compared to the overall high yield corporate bond market. As such, the Fund is expected to exhibit greater sensitivity to market fluctuations.

Substantial Volatility Risk

Substantial volatility risk is the risk that the value of the securities in the Fund’s portfolio may fluctuate, sometimes rapidly and unpredictably at a greater level than the overall market. There is a risk that the Fund could have substantial volatility.

Value Score Risk

Value score risk is the risk that the Fund’s investment in companies whose securities are believed to be undervalued will not appreciate in value as anticipated. Although the Underlying Index is designed to measure a portfolio of bonds of companies with the potential for higher yields and less risk of insolvency relative to the Parent Index, there is no assurance that the Underlying Index or Fund will be comprised of such securities. Accordingly, the Fund may be subject to greater credit risk, price volatility and risk of loss relative to the Parent Index.

The following risk applies to the FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares Credit-Scored US Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund, FlexShares Ready Access Variable Income Fund, FlexShares Core Select Bond Fund, FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, and FlexShares Emerging Markets Quality Low Volatility Index Fund:

Financial Sector Risk

The Fund is subject to the risk that the Fund will be impacted by events affecting the U.S. and/or non-U.S. financial sectors if it invests a relatively large percentage of its assets in those sectors, adversely affecting the Fund’s performance. The U.S. and non-U.S. financial sectors can be significantly affected by changes in interest rates, government regulation, the rate of corporate and consumer debt defaulted, price competitions and the availability and cost of capital funds, among other factors. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares STOXX US ESG Select Index Fund, FlexShares STOXX Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, and FlexShares International Quality Dividend Dynamic Index Fund:

Equity Securities Risk

Each Fund invests in equity securities, primarily in the form of common stocks. Each of these Funds may also invest in preferred stocks and REITs. Preferred stocks are securities that represent an ownership interest providing the holder with claims on the issuer’s earnings and assets before common stock owners but after bond owners. REITs are pooled investment vehicles that invest primarily in real estate or real estate related loans.

Equity securities are subject to changes in value that may be attributable to market perception of a particular issuer, general stock market fluctuations that affect all issuers, or as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The equity securities owned by a Fund may be more volatile and underperform other asset classes and the general securities markets.

The following risks apply to the FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, and FlexShares Emerging Markets Quality Low Volatility Index Fund:

Large Shareholder Risk

Certain shareholders, including other funds advised by the Investment Adviser, may from time to time own a substantial amount of the Fund’s shares. In addition, a third party investor, the Investment Adviser or an affiliate of the Investment Adviser, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

To the extent a significant percentage of the shares of a Fund are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Investment Adviser or an affiliate of the Investment Adviser has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Investment Adviser or an affiliate of the Investment Adviser and may adversely affect a Fund’s performance if the Investment Adviser is forced to sell portfolio securities or invest cash when the Investment Adviser would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of a Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains.

Low Volatility Risk

Although the Underlying Index is designed to have overall volatility that is lower than that of the Parent Index, there is no guarantee it will be successful. Securities or other assets in the Fund’s portfolio may be subject to price volatility and the prices may not be any less volatile than the market as a whole and could be more volatile. Events or financial circumstances affecting individual securities or sectors may increase the volatility of a Fund. The price of a security may fluctuate due to factors affecting markets generally or particular industries. The market prices of the securities or other assets in a Fund’s portfolio may fluctuate, sometimes rapidly and unpredictably. The Fund will continue to seek to track the Underlying Index even if the Underlying Index does not have lower overall volatility than the Parent Index. There is also the risk that a Fund may experience volatility greater than that of its Parent Index as a result of tracking error. A portfolio of securities with greater volatility is generally considered to have a higher risk profile than a portfolio with lower volatility. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of a Fund’s shares may also adversely affect the Fund’s performance to the extent that a Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would to the extent that the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Passive Investment Risk

The FlexShares US Quality Low Volatility Index Fund, FlexShares Developed Markets ex-US Quality Low Volatility Index Fund, FlexShares Emerging Markets Quality Low Volatility Index Fund, FlexShares Morningstar US Market Factor Tilt Index Fund, FlexShares Morningstar Developed Markets ex-US Factor Tilt Index Fund, FlexShares Morningstar Emerging Markets Factor Tilt Index Fund, FlexShares US Quality Large Cap Index Fund, FlexShares STOXX US ESG Select Index Fund, FlexShares STOXX Global ESG Select Index Fund, FlexShares Morningstar Global Upstream Natural Resources Index Fund, FlexShares STOXX Global Broad Infrastructure Index Fund, FlexShares Global Quality Real Estate Index Fund, FlexShares Real Assets Allocation Index Fund, FlexShares Quality Dividend Index Fund, FlexShares Quality Dividend Defensive Index Fund, FlexShares Quality Dividend Dynamic Index Fund, FlexShares International Quality Dividend Index Fund, FlexShares International Quality Dividend Defensive Index Fund, FlexShares International Quality Dividend Dynamic Index Fund, FlexShares iBoxx 3-Year Target Duration TIPS Index Fund, FlexShares iBoxx 5-Year Target Duration TIPS Index Fund, FlexShares Disciplined Duration MBS Index Fund, FlexShares Credit-Scored U.S. Corporate Bond Index Fund, FlexShares Credit-Scored US Long Corporate Bond Index Fund, and FlexShares High Yield Value-Scored Bond Index Fund are not actively managed. Each Fund may be affected by a general decline in the market segments relating to its Underlying Index. Each Fund invests in securities included in, or representative of, its Underlying Index regardless of their investment merit. NTI does not attempt to take defensive positions in any market conditions, including declining markets.
