Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds. More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)	The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.
(2)	Management Fees have been restated to reflect current fees.

returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A
1 Year	$ 66	$ 587
3 Years	$208	$ 773
5 Years	$362	$ 974
10 Years	$810	$1,552

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 51% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in a broadly diversified portfolio of common stocks of large-sized U.S. companies similar in size, at the time of purchase, to those within the Russell 1000^® Index. The largest company by market capitalization in the Russell 1000^® Index was approximately $1.9 trillion as of October 31, 2020 and the median market capitalization of companies in the Index as of the same date was approximately $10.9 billion. The Fund may at times focus its investments in one or more sectors.

The Fund invests in stocks that exhibit less volatile stock price patterns when compared to stocks in the Russell 1000^® Index. The Adviser selects low volatility, undervalued stocks using a unique approach which combines the use of proprietary analytical tools and the qualitative judgments of the investment team. The Adviser’s investment process begins by using tools to rank stocks based on expected risk and expected return and construct preliminary portfolios with the use of fundamental factors. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process. All purchases and sales of portfolio securities, however, are subjected ultimately to the investment team’s qualitative judgments developed from their cumulative investment experience. The entire process is designed to focus on stock risk and company fundamentals through both quantitative and qualitative analysis to balance risk management with return generation. This strategy seeks to provide the Fund with lower downside risk and meaningful upside participation relative to the Russell 1000^® Index.

Equity Funds

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Style Risks. Investments in value stocks are subject to the risk that their intrinsic values may never be realized by the market, that a stock judged to be undervalued may actually be appropriately priced, or that their prices may decline, even though in theory they are already undervalued. Value stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks (e.g., growth stocks).

Sector Risks. Companies with similar characteristics, such as those within similar industries, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down, you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to

increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

Management Risks. The Adviser’s judgments about the attractiveness, value, level of expected volatility, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results. In addition, the Adviser’s strategy may limit the Fund’s gains in rising markets.

Fund Performance

The bar chart and table show the historical performance of the Fund’s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund’s total returns before taxes have varied from year to year, while the table compares the Fund’s average annual total returns to the returns of a broad measure of market performance and an index of funds with similar investment objectives. Please keep in mind that past performance, before and after taxes, does not represent how the Fund will perform in the future. Investors may obtain updated performance information for the Fund at bmofunds.com.

After-tax returns are calculated using the highest historical individual marginal federal income tax rates and do not reflect the effect of any applicable state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors holding shares through tax-deferred programs, such as IRAs or 401(k) plans. After-tax returns are shown only for Class I and after-tax returns for Class A will vary.

The Return After Taxes on Distributions and Sale of Fund Shares may be higher than other return figures when a capital loss is realized on the sale of Fund shares which provides an assumed tax benefit to the shareholder that increases the after-tax return.

The Russell 1000^® Index (Russell 1000^®) measures the performance of the large-cap segment of the U.S. equity universe. It includes approximately 1,000 of the largest securities based on a combination of their market cap and current index membership.

The Lipper Multi-Cap Value Funds Index (LMCVI) tracks the total return performance of the 30 largest mutual funds included in this Lipper category.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Income Risks. The Fund can distribute to shareholders only what it earns. Therefore, if the amount of interest and/or dividends the Fund receives from its investments declines, the amount of dividends shareholders receive from the Fund also will decline. In addition, depending upon market conditions, an income producing common stock that meets the Fund’s investment criteria may not be widely available and/or may be highly concentrated in only a few market sectors. This may limit the ability of the Fund to produce current income.

Style Risks. Investments in value stocks are subject to the risk that their intrinsic values may never be realized by the market, that a stock judged to be undervalued may actually be appropriately priced, or that their prices may decline, even though in theory they are already undervalued. Value stocks can react differently to issuer, political, market, and economic

developments than the market as a whole and other types of stocks (e.g., growth stocks).

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds. More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)

The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.

(2)

BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent class total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 0.54% for Class I, 0.79% for Class A, and 0.39% for Class R6 through December 31, 2021. This

expense limitation agreement may not be terminated prior to December 31, 2021 without the consent of the Fund’s Board of Directors, unless terminated due to the termination of the investment advisory agreement.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2021. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A	Class R6
1 Year	$ 55	$ 577	$ 40
3 Years	$186	$ 752	$138
5 Years	$329	$ 942	$246
10 Years	$744	$1,491	$561

Portfolio Turnover

Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Style Risks. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate.

More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)

The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.

(2)

BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent class total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 0.99% for Class I, 1.24% for Class A, and 0.84% for Class R6 through December 31, 2021. This

expense limitation agreement may not be terminated prior to December 31, 2021 without the consent of the Fund’s Board of Directors, unless terminated due to the termination of the investment advisory agreement.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2021. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A	Class R6
1 Year	$ 101	$ 620	$ 86
3 Years	$ 328	$ 886	$ 281
5 Years	$ 574	$1,172	$ 493
10 Years	$1,277	$1,984	$1,102

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in value-oriented common stocks of medium-sized U.S. companies similar in size, at the time of purchase, to those within the Russell Midcap^® Value Index. The largest company by market capitalization in the Russell Midcap^® Value Index was approximately $41.4 billion as of October 31, 2020 and the median market capitalization of companies in the Index as of the same period was $7.3 billion. The Fund may at times focus its investments in one or more sectors.

The Adviser selects stocks using a unique, value-oriented approach focusing on high quality companies with long-term capital appreciation potential that are available at reasonable prices, which combines the use of proprietary analytical tools

16	EQUITY Funds

and the qualitative judgments of the investment team. In general, the Adviser believes companies that are undervalued relative to their fundamentals and exhibit improving investor interest outperform the market over full market cycles. As a result, the Adviser’s investment process begins by using tools to rank stocks based on expected returns, construct preliminary portfolios with the use of fundamental factors, and manage risk. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process. All purchases and sales of portfolio securities, however, are subjected ultimately to the investment team’s qualitative judgments developed from their cumulative investment experience. The entire process is designed to focus on company fundamentals through both quantitative and qualitative analysis to balance return generation with risk management.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Company Size Risks. Generally, the smaller the market capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase risks and make these companies more likely to fail than companies with larger market capitalizations.

Style Risks. Investments in value stocks are subject to the risk that their intrinsic values may never be realized by the market, that a stock judged to be undervalued may actually be appropriately priced, or that their prices may decline, even

though in theory they are already undervalued. Value stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks (e.g., growth stocks).

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down, you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

Sector Risks. Companies with similar characteristics, such as those within similar industries, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Management Risks. The Adviser’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.

Fund Performance

The bar chart and table show the historical performance of the Fund’s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund’s total returns before taxes have varied from year to year, while the table compares the Fund’s average annual total returns to the returns of a broad measure of market performance and an index of funds with similar investment objectives. Please keep in mind that past performance, before and after taxes, does not represent how the Fund will perform in the future.

Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase risks and make these companies more likely to fail than companies with larger market capitalizations.

Style Risks. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on

price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate.

To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Information Technology Sector Risks. The information technology sector can be significantly affected by rapid obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, government regulation, and general economic conditions.

Management Risks. The Adviser’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds. More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)

The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.

(2)

BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent class total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 0.99% for Class I and 1.24% for Class A through December 31, 2021. This expense limitation agreement may not be terminated prior to December 31, 2021 without the consent of the Fund’s Board of Directors, unless terminated due to the termination of the investment advisory agreement.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2021. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A
1 Year	$ 101	$ 620
3 Years	$ 337	$ 894
5 Years	$ 591	$1,188
10 Years	$1,320	$2,024

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 70% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in growth-oriented common stocks of small-sized U.S. companies similar in size, at the time of purchase, to those within the Russell 2000^® Growth Index. The largest company by market capitalization in the Russell 2000^® Growth Index was approximately $11.8 billion as of October 31, 2020 and the median market capitalization of companies in the Index as of the same period was $915 million. The Fund may at times focus its investments in one or more sectors.

Adviser’s investment process begins by using tools to rank stocks based on expected returns, construct preliminary portfolios with the use of fundamental factors, and manage risk. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process. All purchases and sales of portfolio securities, however, are subjected ultimately to the investment team’s qualitative judgments developed from their cumulative investment experience. The entire process is designed to focus on company fundamentals through both quantitative and qualitative analysis to balance return generation with risk management.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Company Size Risks. Generally, the smaller the market capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase risks and make these companies more likely to fail than companies with larger market capitalizations.

Style Risks. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down, you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

Sector Risks. Companies with similar characteristics, such as those within similar industries, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Healthcare Sector Risks. The profitability of companies in the healthcare sector may be adversely affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Management Risks. The Adviser’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.

Fund Performance

The bar chart and table show the historical performance of the Fund’s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund’s total returns before taxes have varied from year to year, while the table compares the Fund’s average annual total returns to the returns of a broad measure of market performance and an index of funds with similar investment objectives. Please keep in mind that past performance, before and after taxes, does not represent how the Fund will perform in the future. Investors

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds. More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)	The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.
(2)	Management Fees have been restated to reflect current fees.
(3)	BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 0.85% for Class I and 1.10% for Class A through December 31, 2021. This expense limitation agreement may not be terminated prior to December 31, 2021 without the

consent of the Fund’s Board of Directors, unless terminated due to the termination of the investment advisory agreement.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2021. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A
1 Year	$ 87	$ 607
3 Years	$ 400	$ 953
5 Years	$ 735	$1,323
10 Years	$1,684	$2,361

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in equity securities of companies located in the countries included, at the time of purchase, in the MSCI All Country World Index, which includes 23 developed and 26 emerging market countries as of October 31, 2020. The Fund normally invests at least 40% of its net assets in securities located outside the United States and is diversified among at least three countries. The Fund may invest in companies across all market capitalizations and may at times focus its investments in one or more sectors.

The Fund invests in stocks that exhibit less volatile stock price patterns when compared to stocks in the MSCI All Country World Index. The Adviser selects low volatility, undervalued stocks using a unique approach which combines the use of proprietary analytical tools and the qualitative judgments of the investment team. The Adviser’s investment process begins by

32	International and Global Funds

using tools to rank stocks based on expected risk and expected return, and construct preliminary portfolios with the use of fundamental factors. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process. All purchases and sales of portfolio securities, however, are subjected ultimately to the investment team’s qualitative judgments developed from their cumulative investment experience. The entire process is designed to focus on stock risk and company fundamentals through both quantitative and qualitative analysis to balance risk management with return generation. This strategy seeks to provide the Fund with lower downside risk and meaningful upside participation relative to the MSCI All Country World Index.

In determining where a company is located, the Adviser relies on the country where the company is incorporated, but also may consider the country where the company’s revenues are derived and the primary market listing for the class of shares to be purchased. Although the Fund invests primarily in companies located in countries included in the MSCI All Country World Index, the Fund may invest up to 20% of its net assets in companies located in countries not represented in this Index.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Foreign Securities Risks. Investing in foreign securities may involve additional risks, including currency-rate fluctuations, political and economic instability, differences in financial reporting standards, less-strict regulation of the securities markets, and possible imposition of foreign withholding taxes. Furthermore, the Fund may incur higher costs and expenses

when making foreign investments, which will affect the Fund’s total return.

Emerging Markets Risks. Investments in emerging market countries can involve risks in addition to, and greater than, those generally associated with investing in more developed foreign markets. Emerging market countries may have less established legal, political, business, and social frameworks to support securities markets; greater sensitivity to interest rate changes; higher currency exchange rate volatility; and greater risks of inflation, deflation or currency devaluation. Securities in emerging markets also may be less liquid than those in developed markets and foreign investors may be limited in their ability to invest in, and withdraw assets from, these markets.

Currency Risks. To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Company Size Risks. Generally, the smaller the market capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase risks and make these companies more likely to fail than companies with larger market capitalizations.

Style Risks. Investments in value stocks are subject to the risk that their intrinsic values may never be realized by the market, that a stock judged to be undervalued may actually be appropriately priced, or that their prices may decline, even though in theory they are already undervalued. Value stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks (e.g., growth stocks).

Sector Risks. Companies with similar characteristics, such as those within similar industries, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down,

you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

Management Risks. The Adviser’s judgments about the attractiveness, value, level of expected volatility, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results. In addition, the Adviser’s strategy may limit the Fund’s gains in rising markets.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds. More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)	The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.
(2)	Other Expenses for the Class R6 shares are based on estimated amounts for the current fiscal year.
(3)	BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs,

and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 0.90% for Class I, 1.15% for Class A, and 0.75% for Class R6 through December 31, 2021. This expense limitation agreement may not be terminated prior to December 31, 2021 without the consent of the Fund’s Board of Directors, unless terminated due to the termination of the investment advisory agreement.

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 55% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in equity securities of companies located in countries outside of the United States. The Fund invests primarily in companies that are located in the countries included, at the time of purchase, in the MSCI EAFE Index, which includes developed countries outside of North America. However, the Fund may invest up to 20% of its net assets in companies located in countries not represented in this index, including emerging market countries. Equity securities in which the Fund may invest include common stock, preferred

36	International and Global Funds

stock, depositary receipts, rights, warrants, and exchange-traded funds (ETFs). The Fund also may invest in convertible securities (fixed income securities convertible into shares of common or preferred stock).

The Fund’s Adviser focuses on companies that it believes are fundamentally strong, have attractive valuations, possess growing investor interest, and may outperform the overall equity market. Using a unique approach which combines the use of proprietary analytical tools and the qualitative judgments of the investment team, the Adviser selects equity securities that it believes will provide higher returns than the MSCI EAFE Index, its benchmark index. As part of this process, the Adviser considers numerous factors including (but not limited to) valuation, earnings quality, earnings growth potential, and earnings and price momentum. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process. The Adviser invests in those securities it believes will provide a better return relative to their risk than other securities. The Adviser may sell a security for numerous reasons, including if a company’s fundamentals deteriorate or the Adviser believes a company’s fundamentals will deteriorate, if another security appears to provide the potential for a better return relative to its risk, if the Adviser believes the security is no longer attractively valued, or if the Adviser believes the security will no longer help the Fund achieve its investment objective. The Adviser also may sell a security to manage the size of a holding or sector weighting or to fund redemptions.

In determining where a company is located, the Adviser primarily relies on the country where the company is incorporated, but also may consider the country where the company’s revenues are derived and the primary market listing for the class of shares to be purchased. The Fund may invest in companies across all market capitalizations and may at times focus its investments in one or more sectors.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and

decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Foreign Securities Risks. Investing in foreign securities may involve additional risks, including currency-rate fluctuations, political and economic instability, differences in financial reporting standards, less-strict regulation of the securities markets, and possible imposition of foreign withholding taxes. Furthermore, the Fund may incur higher costs and expenses when making foreign investments, which will affect the Fund’s total return.

Emerging Markets Risks. Investments in emerging market countries can involve risks in addition to, and greater than, those generally associated with investing in more developed foreign markets. Emerging market countries may have less established legal, political, business, and social frameworks to support securities markets; greater sensitivity to interest rate changes; higher currency exchange rate volatility; and greater risks of inflation, deflation or currency devaluation. Securities in emerging markets also may be less liquid than those in developed markets and foreign investors may be limited in their ability to invest in, and withdraw assets from, these markets.

Geographic Concentration Risks. To the extent the Fund invests a substantial amount of its assets in securities of issuers located in a single country or geographic region, the Fund’s performance may be more susceptible to any changes to the regulatory, political, social or economic conditions in such country or geographic region.

Currency Risks. To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Company Size Risks. Generally, the smaller the market capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase risks and make these companies more likely to fail than companies with larger market capitalizations.

Sector Risks. Companies with similar characteristics, such as those within similar industries, may be grouped together in

International and Global Funds

37

broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down, you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

Convertible Security Risks. Convertible securities are fixed income securities that the Fund has the option to exchange for equity securities at a specified conversion price. Consequently, the value of the convertible security may be exposed to the stock market risk of the underlying stock, or may be exposed to the interest rate or credit risk of the issuer. Because both interest rate and market movements can influence its value, a convertible security is usually not as sensitive to interest rate changes as a similar fixed-income security, nor is it as sensitive to changes in share price as its underlying stock. Convertible securities also are subject to credit risks that affect debt securities in general.

Exchange-Traded Funds Risks. By investing in an ETF, a risk exists that the value of the underlying securities of the ETF may decrease. In addition, the market price of ETF shares may trade at a discount to their net asset value or an active trading market for ETF shares may not develop or be maintained. ETFs in which the Fund invests typically will not be able to replicate exactly the performance of the indices they track. The Fund also will bear its proportionate share of the ETF’s fees (including management and advisory fees) and expenses.

Management Risks. The Adviser’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.

Class I—Annual Total Returns (calendar years 2016-2019)

The return for the Class I shares of the Fund from January 1, 2020 through September 30, 2020 was (11.03)%.

During the periods shown in the bar chart for the Fund:

Because Class R6 shares have not yet commenced operations, no performance data is available. Class R6 shares are expected to have substantially similar annual returns as Class I shares because the shares are invested in the same portfolio of securities. The performance of Class R6 shares is expected to be higher than Class I shares because Class R6 shares have lower Total Annual Fund Operating Expenses.

Investment Objective:

To provide capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds. More information about these and other discounts and waivers is available from your financial professional and under “How to Buy Shares – Purchase of Class A Shares – Class A Shares – Sales Charge” on page 93 of this Prospectus, under “How to Buy Shares – Class A Shares – Waivers and Reductions of Sales Charges” beginning on page 94 of this Prospectus, under “Appendix–Sales Charge Waivers” on page 128 of this Prospectus, and “How to Buy Shares” beginning on page B-36 of the Fund’s Statement of Additional Information.

(1)

The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.

(2)

The management fee disclosed is a blended fee based on the Fund’s total assets as of August 31, 2020. Under the investment advisory agreement, the Fund pays a management fee of 0.735% on the Fund’s first $500 million of average daily net assets, 0.72% on the next $200 million of average daily net assets, 0.62% on the next $100 million of average daily net assets, and 0.56% on assets in excess of $800 million.

(3)

BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 0.94% for Class I, 1.19% for Class A, and 0.79% for Class R6 through December 31, 2021. This expense limitation agreement may not be terminated prior to December 31, 2021 without the consent of the Fund’s Board of Directors, unless terminated due to the termination of the investment advisory agreement.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2021. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A	Class R6
1 Year	$ 96	$ 615	$ 81
3 Years	$ 302	$ 861	$254
5 Years	$ 525	$1,126	$443
10 Years	$1,165	$1,881	$989

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in equity securities of companies located in a number of countries outside the United States. The Fund invests primarily in companies that are located in the countries included, at the time of purchase, in the MSCI EAFE Index, which includes developed countries outside of North America. Although the Fund may invest in companies

40	International and Global Funds

across all market capitalizations, the Fund invests primarily in companies that, at the time of purchase, have a minimum market capitalization of $2 billion. The Fund may at times focus its investments in one or more sectors.

The Fund’s sub-adviser is Pyrford International Ltd. (Pyrford), an affiliate of the Adviser. Pyrford seeks to minimize losses by adopting a highly defensive investment stance at times of perceived high risk, characterized by high valuation levels or high levels of financial leverage. The Fund does not target a specific volatility level, but aims to deliver volatility significantly below that of the MSCI EAFE Index by being zero weight in any country, sector, or stock that Pyrford believes has very poor value as measured by established fundamental value metrics (such as dividend yields, return on equity, and P/E ratios). Pyrford also integrates environmental, social, and governance (ESG) considerations into its investment process.

In determining where a company is located, the sub-adviser primarily relies on the country where the company is incorporated, but also may consider the country where the company’s revenues are derived and the primary market listing for the class of shares to be purchased. Although the Fund invests primarily in companies that are included in the MSCI EAFE Index, the Fund may invest up to 20% of its net assets in companies located in countries not represented in this index, including emerging market countries.

The Fund may invest in forward foreign currency exchange contracts, a type of derivative instrument, for purposes of hedging its exposure to non-U.S. currencies. From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Common Stock Risks. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Holders of common stocks are generally subject to greater risk than holders of preferred stocks and debt obligations of the same issuer because common stockholders generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors.

Foreign Securities Risks. Investing in foreign securities may involve additional risks, including currency-rate fluctuations, political and economic instability, differences in financial reporting standards, less-strict regulation of the securities markets, and possible imposition of foreign withholding taxes. Furthermore, the Fund may incur higher costs and expenses when making foreign investments, which will affect the Fund’s total return.

Emerging Markets Risks. Investments in emerging market countries can involve risks in addition to, and greater than, those generally associated with investing in more developed foreign markets. Emerging market countries may have less established legal, political, business, and social frameworks to support securities markets; greater sensitivity to interest rate changes; higher currency exchange rate volatility; and greater risks of inflation, deflation or currency devaluation. Securities in emerging markets also may be less liquid than those in developed markets and foreign investors may be limited in their ability to invest in, and withdraw assets from, these markets.

Currency Risks. To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down, you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

Company Size Risks. Generally, the smaller the market capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase

International and Global Funds

41

risks and make these companies more likely to fail than companies with larger market capitalizations.

Sector Risks. Companies with similar characteristics, such as those within similar industries, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Forward Foreign Currency Exchange Contracts Risks. Forward foreign currency exchange contracts are subject to currency risks. A forward foreign currency exchange contract also may result in losses in the event of a default or bankruptcy of the counterparty. Forward foreign currency exchange contracts may limit potential gain from a positive change in the relationship between the U.S. dollar and foreign currencies.

Management Risks. Pyrford’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.

Fund Performance

The bar chart and table show the historical performance of the Fund’s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund’s total returns before taxes have varied from year to year, while the table compares the Fund’s average annual total returns to the returns of a broad measure of market performance and an index of funds with similar investment objectives. Please keep in mind that past performance, before and after taxes, does not represent how the Fund will perform in the future. Investors may obtain updated performance information for the Fund at bmofunds.com.

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of certain BMO Funds.

(1)	The Maximum Deferred Sales Charge on Class A shares is applied only to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.
(2)	Other Expenses have been restated to reflect current fees.
(3)	BMO Asset Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee and reimburse expenses to the extent necessary to prevent total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Fund’s business, and Acquired Fund Fees and Expenses) from exceeding 1.15% for Class I and 1.40% for Class A through December 31, 2021. This expense limitation agreement may not be terminated prior to December 31, 2021 without the

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2021. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class I	Class A
1 Year	$ 117	$ 635
3 Years	$ 389	$ 943
5 Years	$ 681	$1,273
10 Years	$1,513	$2,203

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in equity securities of foreign companies located in emerging markets or whose primary business activities or principal trading markets are in emerging markets. The Fund may invest in equity securities of any market capitalization and may at times focus its investments in one or more sectors. The Fund’s sub-adviser, LGM Investments Limited (LGM Investments), an affiliate of the Adviser, considers emerging markets to be those markets in any country other than Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, the United Kingdom, and the United States. LGM Investments may make adjustments to the list of emerging markets countries from time to time based on economic criteria, market changes, or other factors.

LGM Investments uses a “bottom-up,” fundamental approach to identify quality, growth companies typically with dominant industry positions, strong balance sheets, and cash flows to support a sustainable dividend payout. LGM also integrates environmental, social, and governance (ESG) considerations into its investment process.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Foreign Securities Risks. Investing in foreign securities may involve additional risks, including currency-rate fluctuations, political and economic instability, differences in financial reporting standards, less-strict regulation of the securities markets, and possible imposition of foreign withholding taxes. Furthermore, the Fund may incur higher costs and expenses when making foreign investments, which will affect the Fund’s total return.

Geographic Concentration Risks. To the extent the Fund invests a substantial amount of its assets in securities of issuers located in a single country or geographic region, the Fund’s performance may be more susceptible to any changes to the regulatory, political, social or economic conditions in such country or geographic region.

Currency Risks. To the extent that the Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Consumer Staples Sector Risks. Companies in the consumer staples sector may be adversely affected by changes in consumer spending, competition, demographics and consumer preferences. Companies in this sector are also affected by changes in government regulation, world events and economic conditions. This sector can also be significantly affected by, among other things, changes in price and availability of underlying commodities, rising energy prices and global and economic conditions. Certain companies in the consumer staples sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Financial Services Sector Risks. Financial services companies may be adversely affected by changes in regulatory framework or interest rates that may negatively affect financial services businesses; exposure of a financial institution to a non-diversified or concentrated loan portfolio; exposure to financial leverage and/or investments or agreements that, under certain circumstances, may lead to losses; and the risk that a market shock or other unexpected market, economic, political,

45

regulatory, or other event might lead to a sudden decline in the values of most or all financial services companies.

Stock Market Risks. The Fund is subject to fluctuations in the stock market, which has periods of increasing and decreasing values. Stocks are more volatile than debt securities. The value of equity securities purchased by the Fund may decline if the financial condition of the companies in which the Fund invests declines or if overall market and economic conditions deteriorate. If the value of the Fund’s investments goes down, you may lose money. U.S. and international markets have experienced significant volatility in recent years, which may increase the risks of investing in the securities held by the Fund. Policy changes by the U.S. government and/or Federal Reserve, such as raising interest rates, also could cause increased volatility in financial markets, which could have a negative impact on the Fund. Adverse market events also may lead to increased shareholder redemptions, which could cause the Fund to experience a loss or difficulty in selling investments to meet such redemptions.

The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Municipal Securities Risks. Municipal bonds are subject to risks based on many factors, including economic and regulatory developments, changes or proposed changes in the federal and state tax structure, deregulation, court rulings, and other factors. The value of municipal securities may be affected more by supply and demand factors or the creditworthiness of the issuer than by market interest rates. Repayment of municipal securities depends on the ability of the issuer or project backing such securities to generate taxes or revenues. There is a risk that interest may be taxable on a municipal security that is otherwise expected to produce tax-exempt interest.

Sector Risks. The Fund may invest its assets in municipal securities that finance similar projects, such as those relating to education, health care, transportation, and utilities. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Income Risks. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest its assets in lower-yielding securities.

Interest Rate Risks. Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed

income securities fall. Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Interest rate changes also are influenced by a number of factors including government or central bank policy, inflation expectations, and supply and demand.

Credit Risks. Credit risk is the possibility that an issuer or counterparty will default on a security or repurchase agreement by failing to pay interest or principal when due. If an issuer defaults, the Fund may lose money. Lower credit ratings correspond to higher credit risk. Bonds rated lower than BBB or Baa have speculative characteristics.

Call Risks. If the securities in which the Fund invests are redeemed by the issuer before maturity (or “called”), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund’s yield. This will most likely happen when interest rates are declining.

High Yield Securities Risks. High yield securities, also referred to as “junk bonds” or non-investment grade securities, are debt securities rated lower than BBB by Standard & Poor’s or Baa by Moody’s Investors Service. These securities tend to be more sensitive to economic conditions than are higher-rated securities, generally involve more credit risk than securities in the higher-rated categories, and are predominantly considered to be speculative. The issuers of high yield securities are typically more leveraged and the risk of loss due to default by an issuer of high yield securities is significantly greater than issuers of higher-rated securities because such securities are generally unsecured and are often subordinated to other creditors. The Fund may have difficulty disposing of certain high yield securities because a thin trading market for such securities may exist.

Liquidity Risks. Liquidity risk refers to the possibility that the trading market for a particular type of security becomes less liquid or the Fund may not be able to sell or buy a security or close out an investment contract at a favorable price or time. The market for lower-quality debt instruments, including junk bonds, is generally less liquid than the market for higher-quality debt instruments. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. Infrequent trading of securities also may lead to an increase in their price volatility. Illiquidity may result from political, economic, or issuer specific events or overall market disruptions.

Portfolio Turnover Risks. A high portfolio turnover rate (100% or more) may result in the realization and distribution to shareholders of a greater amount of capital gains than if the Fund had a low portfolio turnover rate. A higher tax liability may result. High portfolio turnover also may result in higher

transaction costs, which may negatively affect Fund performance.

Management Risks. The Adviser’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.

The Adviser selects Fund investments after assessing factors such as the cyclical trend in interest rates, the shape of the municipal yield curve, tax rates, sector valuation, and municipal bond supply factors. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Municipal Securities Risks. Municipal bonds are subject to risks based on many factors, including economic and regulatory developments, changes or proposed changes in the federal and state tax structure, deregulation, court rulings, and other factors. The value of municipal securities may be affected more by supply and demand factors or the creditworthiness of the issuer than by market interest rates. Repayment of municipal securities depends on the ability of the issuer or project backing such securities to generate taxes or revenues. There is a risk that interest may be taxable on a municipal security that is otherwise expected to produce tax-exempt interest.

Sector Risks. The Fund may invest its assets in municipal securities that finance similar projects, such as those relating to education, health care, transportation, and utilities. To the extent the Fund invests its assets in a particular sector, the Fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Healthcare Sector Risks. The profitability of companies in the healthcare sector may be adversely affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and

may be thinly capitalized and susceptible to product obsolescence.

Income Risks. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest its assets in lower-yielding securities.

Interest Rate Risks. Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. Interest rate changes have a greater effect on the price of fixed income securities with longer maturities.

into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Corporate Debt Securities Risks. Corporate debt securities are fixed income securities issued by businesses. The market value of corporate debt may be affected by changes in the market rate of interest, the credit rating of the corporation, the corporation’s performance, and perceptions of the corporation in the market place. Corporate issuers may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Income Risks. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest its assets in lower-yielding securities.

Interest Rate Risks. Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Interest rate changes also are influenced by a number of factors including government or central bank policy, inflation expectations, and supply and demand.

If an issuer defaults, the Fund may lose money. Lower credit ratings correspond to higher credit risk. Bonds rated lower than BBB or Baa have speculative characteristics.

Call Risks. If the securities in which the Fund invests are redeemed by the issuer before maturity (or “called”), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund’s yield. This will most likely happen when interest rates are declining.

Asset-Backed/Mortgage-Backed Securities Risks. Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund’s yield will be reduced if cash from

prepaid securities is reinvested in securities with lower interest rates. The risk of prepayment also may decrease the value of mortgage-backed securities. Asset-backed securities may have a higher level of default and recovery risk than mortgage-backed securities. Asset-backed securities may also be subject to greater risk of default during periods of economic downturn than other securities, which could result in possible losses to the Fund. In addition, the secondary market for asset-backed securities may not be as liquid as the market for other securities which may result in the Fund experiencing difficulty in selling or valuing asset-backed securities. Both of these types of securities may decline in value because of mortgage foreclosures or defaults on the underlying obligations. Credit risk is greater for mortgage-backed and asset-backed securities that are subordinate to another security.

Repurchase Agreements Risk. Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed upon time and price. Repurchase agreements are subject to market risk with respect to the collateral securing the repurchase agreements and credit risk with respect to the counterparty. In the event of a bankruptcy or other default by the counterparty, the Fund could experience delays and potential losses in liquidating the underlying security.

Government Obligations Risks. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law (such as Fannie Mae or Freddie Mac). As a result, a risk exists that these entities will default on a financial obligation.

Liquidity Risks. Liquidity risk refers to the possibility that the trading market for a particular type of security becomes less liquid or the Fund may not be able to sell or buy a security or close out an investment contract at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. Infrequent trading of securities also may lead to an increase in their price volatility. Illiquidity may result from political, economic, or issuer specific events or overall market disruptions.

Portfolio Managers. Robert Wimmel, Thomas Byron, and Brian Sipich are co-portfolio managers of the Fund and are jointly and primarily responsible for the day-to-day management of the Fund’s portfolio. Mr. Wimmel, Head of Tax Exempt Fixed Income and a Managing Director of the Adviser, joined the

yield, securities are commonly referred to as “junk bonds.” Investment grade securities are: securities rated BBB- or higher by Standard & Poor’s Ratings Services (S&P) or Baa3 or higher by Moody’s Investors Service, Inc. (Moody’s) or an equivalent rating by another nationally recognized statistical rating organization (NRSRO), or unrated securities determined by the Adviser to be of comparable quality.

The Fund’s securities may be denominated in either U.S. dollars or foreign currencies. While the Fund’s assets are predominantly U.S. dollar denominated, the Fund also may invest up to 25% of its assets in foreign currency denominated debt securities, all or a portion of which may be emerging markets debt securities. The Fund may invest up to 10% of its assets in common stocks; however, most common stocks generally will be acquired from conversions of convertible bonds or as residual interests from other fixed income securities. The Adviser also integrates environmental, social, and governance (ESG) considerations into its investment process.

From time to time, the Fund maintains a portion of its assets in cash. The Fund may increase its cash holdings in response to market conditions or in the event attractive investment opportunities are not available.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. The net asset value of the Fund will vary and you could lose money by investing in the Fund. In addition, the Fund is subject to the following risks.

Corporate Debt Securities Risks. Corporate debt securities are fixed income securities issued by businesses. The market value of corporate debt may be affected by changes in the market rate of interest, the credit rating of the corporation, the corporation’s performance, and perceptions of the corporation in the market place. Corporate issuers may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Income Risks. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest its assets in lower-yielding securities.

Interest Rate Risks. Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Interest rate changes also are influenced by a number of factors

including government or central bank policy, inflation expectations, and supply and demand.

Credit Risks. Credit risk is the possibility that an issuer or counterparty will default on a security or repurchase agreement by failing to pay interest or principal when due. If an issuer defaults, the Fund may lose money. Lower credit ratings correspond to higher credit risk. Bonds rated lower than BBB or Baa have speculative characteristics.

Call Risks. If the securities in which the Fund invests are redeemed by the issuer before maturity (or “called”), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund’s yield. This will most likely happen when interest rates are declining.

High Yield Securities Risks. High yield securities, also referred to as “junk bonds” or non-investment grade securities, are debt securities rated lower than BBB by Standard & Poor’s or Baa by Moody’s Investors Service. These securities tend to be more sensitive to economic conditions than are higher-rated securities, generally involve more credit risk than securities in the higher-rated categories, and are predominantly considered to be speculative. The issuers of high yield securities are typically more leveraged and the risk of loss due to default by an issuer of high yield securities is significantly greater than issuers of higher-rated securities because such securities are generally unsecured and are often subordinated to other creditors. The Fund may have difficulty disposing of certain high yield securities because a thin trading market for such securities may exist.

Foreign Securities Risks. Investing in foreign securities may involve additional risks, including currency-rate fluctuations, political and economic instability, differences in financial reporting standards, less-strict regulation of the securities markets, and possible imposition of foreign withholding taxes. Furthermore, the Fund may incur higher costs and expenses when making foreign investments, which will affect the Fund’s total return.

Emerging Markets Risks. Investments in emerging market countries can involve risks in addition to, and greater than, those generally associated with investing in more developed foreign markets. Emerging market countries may have less established legal, political, business, and social frameworks to support securities markets; greater sensitivity to interest rate changes; higher currency exchange rate volatility; and greater risks of inflation, deflation or currency devaluation. Securities in emerging markets also may be less liquid than those in developed markets and foreign investors may be limited in their ability to invest in, and withdraw assets from, these markets.

Asset-Backed/Mortgage-Backed Securities Risks. Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund’s yield will be reduced if cash from prepaid securities is reinvested in securities with lower interest rates. The risk of prepayment also may decrease the value of mortgage-backed securities. Asset-backed securities may have a higher level of default and recovery risk than mortgage-backed securities. Asset-backed securities may also be subject to greater risk of default during periods of economic downturn than other securities, which could result in possible losses to the Fund. In addition, the secondary market for asset-backed securities may not be as liquid as the market for other securities which may result in the Fund experiencing difficulty in selling or valuing asset-backed securities. Both of these types of securities may decline in value because of mortgage foreclosures or defaults on the underlying obligations. Credit risk is greater for mortgage-backed and asset-backed securities that are subordinate to another security.

Repurchase Agreements Risk. Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed upon time and price. Repurchase agreements are subject to market risk with respect to the collateral securing the repurchase agreements and credit risk with respect to the counterparty. In the event of a bankruptcy or other default by the counterparty, the Fund could experience delays and potential losses in liquidating the underlying security.

Government Obligations Risks. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law (such as Fannie Mae or Freddie Mac). As a result, a risk exists that these entities will default on a financial obligation.

Liquidity Risks. Liquidity risk refers to the possibility that the trading market for a particular type of security becomes less liquid or the Fund may not be able to sell or buy a security or close out an investment contract at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. Infrequent trading of securities also may lead to an increase in their price volatility. Illiquidity may result from political, economic, or issuer specific events or overall market disruptions.

Management Risks. The Adviser’s judgments about the attractiveness, value, and potential appreciation of the Fund’s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund’s managers will produce the desired results.
