This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund&#8217;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-year example reflect the Adviser&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) Example This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

The example also assumes that your investment has a 5% return each year and that the Fund&#8217;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&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: Portfolio Turnover The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; 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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 127% 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 to those within the Russell 1000<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> Value Index. These large-sized companies, at the time of purchase, generally have market capitalizations in the range of companies in the Russell 1000<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> Value Index. The largest company by market capitalization in the Russell 1000<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> Value Index was approximately $408.2 billion as of August 31, 2012 and the median market capitalization of companies in the Index as of the same period was $4.9 billion. The Adviser selects stocks using a unique, quantitative, value-oriented approach. Principal Risks 92 66 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.<br/><br/><b>Stock Market Risks.</b> 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. If the value of the Fund&#8217;s investments goes down, you may lose money.<br/><br/><b>Sector Risks.</b> Companies with similar characteristics, such as those within the same industry, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Style Risks.</b> 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).<br/><br/><b>Management Risks.</b> The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br/><br/><b>Portfolio Turnover Risks.</b> A high portfolio 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. Therefore, you may have higher tax liability. High portfolio turnover also may result in higher transaction costs, which may negatively affect Fund performance. Fund Performance The bar chart and table show the historical performance of the Fund&#8217;s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund&#8217;s total returns before taxes have varied from year to year, while the table compares the Fund&#8217;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 www.bmofundsus.com. <b>Class Y&#8212;Annual Total Returns</b> (calendar years 2002-2011) <b>Average Annual Total Returns</b> through 12/31/11 409 331 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.

To the extent the Fund invests its assets in a particular sector, the Fund&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Income Risks. </b> The Fund can only distribute to shareholders 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 will also decline. In addition, depending upon market conditions, income producing common stock that meets the Fund&#8217;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.<br/><br/><b>Style Risks. </b> 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).<br/><br/><b>Management Risks. </b> The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect.

The Fund invests primarily in companies that are located in the countries included in the MSCI EAFE Index, which includes developed countries outside of North America. Although the Fund may invest in companies across all market capitalizations, the Fund invests primarily in companies that, at the time of purchase, have a minimum market capitalization of $2 billion.<br/><br/>The Fund&#8217;s sub-adviser is Pyrford International Ltd. (&#8220;Pyrford&#8221;). 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).<br/><br/>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&#8217;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. 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.<br/><br/><b>Foreign Securities Risks.</b> 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&#8217;s total return.<br/><br/><b>Emerging Markets Risks.</b> Investments in emerging markets can involve risks in addition to and greater than those generally associated with investing in more developed foreign markets, which may make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets.<br/><br/><b>Stock Market Risks.</b> 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. If the value of the Fund&#8217;s investments goes down, you may lose money.<br/><br/><b>Small Company Risks.</b> 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.<br/><br/><b>Management Risks.</b> Pyrford&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect.

The Fund normally invests at least 40% of its net assets in securities located outside the United States and will be diversified among at least three different countries. The Fund invests primarily in securities that are principally traded on established global markets with a particular emphasis on issuers traded on established markets located in North America, Europe (including the UK), and the Asia Pacific Region (including Japan). Although the Fund may invest in companies 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 invest up to 20% of its net assets in emerging market countries and may hold up to 25% of its net assets in cash or cash equivalents. The Fund may invest without limitation in investment-grade sovereign debt securities.<br/><br/>Equity securities in which the Fund may invest include common stocks, preferred stocks, warrants to purchase common stocks or preferred stocks, securities convertible into common or preferred stocks, American Depositary Receipts, European Depositary Receipts, or other similar securities representing common stock of non-U.S. issuers. From time to time, the Fund may invest in exchange-traded funds.<br/><br/>In investing in investment-grade sovereign debt securities, the Fund seeks to add value through geographical allocations and duration decisions made by the sub-adviser on the basis of established fundamental value metrics (such as dividend yields, return on equity, and price/earnings ratios).<br/><br/>The Fund attempts to achieve total returns at least 400 basis points above the U.S. Consumer Price Index. No guarantee exists that the Fund will meet the total return goal. A key factor in generating total returns is utilizing an investment approach designed to minimize negative returns when markets fall, through both strategic asset allocation among equities, sovereign debt securities, and cash and investment selection on a global basis. Pyrford seeks to minimize losses by avoiding asset classes and securities that are perceived to be high risk on the basis of established fundamental value metrics (such as dividend yields, return on equity, and price/earnings ratios). This approach may restrict the Fund from fully participating when markets rise.

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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 128% of the average value of its portfolio. Principal Investment Strategies Under normal circumstances, the Fund invests at least 80% of its assets in municipal securities, the income from which is exempt from federal income tax (including the federal alternative minimum tax (AMT)). The Fund normally maintains an average dollar-weighted effective maturity of one year or less. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date.<br/><br/>The Fund invests primarily in municipal securities within the investment grade category (i.e., rated BBB or Baa, or higher, or unrated and considered by the Adviser to be comparable in quality) at the time of purchase. Municipal securities include fixed and floating rate debt obligations of states, territories, and possessions of the U.S., and political subdivisions and financing authorities of these entities that provide income exempt from federal income tax (including federal AMT). Fund investments are selected 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. 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 (NAV) 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.<br/><br/><b>Interest Rate Risk. </b>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.<br/><br/><b>Credit Risk. </b>Credit risk is the possibility that an issuer will default on a security 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.<br/><br/><b>Call Risk. </b>If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining.<br/><br/><b>Liquidity Risk. </b>Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility.<br/><br/><b>Municipal Securities Risk. </b>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 the interest on an otherwise tax-exempt municipal security may be subject to federal income tax.<br/><br/><b>Management Risk. </b>The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br/><br/><b>Sector Risks. </b>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&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Investments in Other Investment Companies Risks. </b>The Fund may invest in securities issued by other investment companies, including exchange-traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses.<br/><br/><b>Portfolio Turnover Risks. </b>A high portfolio 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. Therefore, you may have higher tax liability. High portfolio turnover also may result in higher transaction costs, which may negatively affect Fund performance.

In addition, the Fund is subject to the following risks.<br/><br/><b>Stock Market Risks.</b> 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. If the value of the Fund&#8217;s investments goes down, you may lose money.<br/><br/><b>Sector Risks.</b> Companies with similar characteristics, such as those within the same industry, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Style Risks.</b> 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.<br/><br/><b>Company Size Risks.</b> 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.

To the extent the Fund invests its assets in a particular sector, the Fund&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Sovereign Debt Risk.</b> Sovereign debt instruments are subject to the risk that a governmental entity may be unable to pay interest or repay principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, or political concerns. If a governmental entity defaults on an obligation, the Fund may have limited recourse against the defaulting government and may lose its investment. Financial markets have recently experienced increased volatility due to the uncertainty surrounding the sovereign debt of certain European countries.<br/><br/><b>Foreign Securities Risks.</b> 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&#8217;s total return.<br/><br/><b>Emerging Markets Risk. </b> The risk that countries in emerging markets are generally more volatile and can have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues.<br/><br/><b>Interest Rate Risks.</b> 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.<br/><br/><b>Income Risks.</b> The Fund&#8217;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.<br/><br/><b>Credit Risks.</b> 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.<br/><br/><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility.<br/><br/><b>Small Company Risks.</b> 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.<br/><br/><b>Management Risks. </b> Pyrford&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br/><br/><b>Style Risks.</b> 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). The net asset value of the Fund will vary and you could lose money by investing in the Fund. 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. Fund Performance The bar chart and table show the historical performance of the Fund&#8217;s shares and provide some indication of the risks of investing in the Fund.

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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 190% of the average value of its portfolio. This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Example BMO Intermediate Tax-Free Fund Portfolio Turnover This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund&#8217;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&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: Investment Objective: To provide a high level of current income exempt from federal income tax consistent with preservation of capital. 65 40 Principal Investment Strategies Principal Risks 231 151 The Fund invests at least 80% of its assets in bonds. Fund investments include corporate, asset-backed, and mortgage-backed securities with a minimum rating in the lowest investment grade category (i.e., rated BBB or Baa, or higher, or unrated and considered by the Adviser to be comparable in quality) at the time of purchase and repurchase agreements and U.S. government securities. The Adviser changes the Fund&#8217;s weightings in these sectors as it deems appropriate and uses macroeconomic, credit, and market analysis to select portfolio securities. The Fund normally maintains an average dollar-weighted effective maturity of two to eight years. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date.

Shareholder Fees (fees paid directly from your investment) 0 Portfolio Turnover 0 The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; 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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 63% of the average value of its portfolio. Example 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. <br /><br /><b>Interest Rate Risks.</b> 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. <br /><br /><b>Credit Risks.</b> 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. <br /><br /><b>Call Risks.</b> If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining. <br /><br /><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility. <br /><br /><b>Asset-Backed/Mortgage-Backed Securities Risks.</b> Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund&#8217;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. 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 securities that are subordinate to another security. <br /><br /><b>Government Obligations Risks.</b> 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. As a result, there is risk that these entities will default on a financial obligation. <br /><br /><b>Management Risks.</b> The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results. <br /><br /><b>Portfolio Turnover Risks.</b> A high portfolio 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. Therefore, you may have higher tax liability. High portfolio turnover also may result in higher transaction costs, which may negatively affect Fund performance. <br /><br /><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies, including exchange traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses. Principal Investment Strategies The Fund invests at least 80% of its assets in fixed income securities. Fund investments include corporate, asset-backed, and mortgage-backed securities with a minimum rating in the lowest investment grade category (i.e., rated BBB or Baa, or higher, or unrated and considered by the Adviser to be comparable in quality) at the time of purchase and bank instruments, repurchase agreements, and U.S. government securities. In addition, the Fund may invest in securities issued by other investment companies that in turn invest in bonds and other financial instruments. The Adviser changes the Fund&#8217;s weightings in these fixed income asset classes as it deems appropriate and uses macroeconomic, credit, and market analysis to select portfolio securities. The Fund normally maintains an average dollar-weighted effective maturity of six months to three years. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date.

The Fund also may invest in the securities of U.S. government-sponsored entities that are supported by the full faith and credit of the U.S. government, such as the Government National Mortgage Association (Ginnie Mae). Finally, the Fund may invest in the securities of governmental entities that have no explicit financial support from the U.S. government, but are regarded as having implied support because the U.S. government sponsors their activities, including the Farm Credit Administration and the Financing Corporation. The Fund also may invest in non-agency asset-backed and mortgage-backed securities.<br /><br />The Adviser considers macroeconomic conditions and uses credit and market analysis in developing the overall portfolio strategy. Current and historical interest rate relationships are used to evaluate market sectors and individual securities.

In addition, the Fund is subject to the following risks.<br /><br /><b>Interest Rate Risks.</b> 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.<br /><br /><b>Credit Risks.</b> 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.<br /><br /><b>Call Risks.</b> If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining.<br /><br /><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility.<br /><br /><b>Asset-Backed/Mortgage-Backed Securities Risks.</b> Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund&#8217;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. 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 securities that are subordinate to another security.<br /><br /><b>Government Obligations Risks.</b> 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. As a result, there is risk that these entities will default on a financial obligation.<br /><br /><b>Management Risks.</b> The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br /><br /><b>Portfolio Turnover Risks.</b> A high portfolio 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. Therefore, you may have higher tax liability. High portfolio turnover also may result in higher transaction costs, which may negatively affect Fund performance.<br /><br /><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies, including exchange traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses. Fund Performance 56 46 209 144 The bar chart and table show the historical performance of the Fund&#8217;s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund&#8217;s total returns before taxes have varied from year to year, while the table compares the Fund&#8217;s average annual total returns to the returns of a broad measure of market performance and an index of funds with similar investment objectives.

Fund investments include municipal securities with a minimum rating in the lowest investment grade category (i.e., rated BBB or Baa, or higher, or unrated and considered by the Adviser to be comparable in quality) at the time of purchase. Municipal securities include debt obligations of states, territories, and possessions of the U.S. and political subdivisions, and financing authorities of these entities that provide income exempt from federal income tax (including federal AMT). 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 Fund normally maintains an average dollar-weighted effective maturity of three to ten years. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date. 0.0409 Principal Risks 0.0461 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) -0.1267 0.0549 0.2681 0.0191 0.0801 0.0525 0.0818 0.0308 0.0424 0.0233 0.0472 0.004 0.0585 0.004 0.0007 0 0.1271 0 0.0708 0.052 0.0042 0.0017 0.0001 0.0001 0.0083 0.0058 -0.0002 -0.0002 2012-09-30 0.0353 Best quarter The return for the Class Y shares of the Fund from January 1, 2012 through September 30, 2012 Example <div style="display:none">~ http://www.bmofundsus.com/role/ScheduleExpenseExampleBMOShortIntermediateBondFund column period compact * ~</div> 2009-06-30 2012-09-30 This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

The Adviser&#8217;s strategy for achieving total return is to adjust the Fund&#8217;s weightings in these sectors as it deems appropriate. The Adviser uses macroeconomic, credit, and market analysis to select portfolio securities. The Fund normally maintains an average dollar-weighted effective maturity of three to ten years. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date.

Total Annual Fund Operating Expenses shown will not correlate to the Fund&#8217;s ratios of expenses to average net assets appearing in the Financial Highlights tables, which do not include Acquired Fund Fees and Expenses. The Fund invests at least 80% of its assets in bonds. Fund investments include corporate, asset-backed, mortgage-backed and U.S. government securities. Although the Fund will invest primarily in securities with a minimum rating in the lowest investment grade category (i.e., rated BBB or Baa, or higher, or unrated and considered by the sub-adviser to be comparable in quality) at the time of purchase, the Fund may invest up to 20% of its assets in debt securities that are below investment grade, also known as high yield securities or &#8220;junk bonds.&#8221; While the Fund&#8217;s assets are predominantly U.S. dollar denominated, the Fund also may invest up to 20% of its assets in foreign debt securities, all or a portion of which may be emerging markets debt securities. <br /><br />The Fund&#8217;s investment strategy is referred to as &#8220;Core Plus&#8221; because the Fund&#8217;s sub-adviser, Taplin, Canida &amp; Habacht, LLC (TCH), an affiliate of the Adviser, has the ability to add high yield securities and emerging markets debt securities to a core portfolio of investment grade fixed income securities. TCH&#8217;s strategy for achieving total return is to adjust the Fund&#8217;s weightings in these sectors as it deems appropriate. TCH uses macroeconomic, credit, and market analysis to select portfolio securities. The Fund normally maintains an average dollar-weighted effective maturity of three to ten years. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date. 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.<br /><br /><b>Interest Rate Risks.</b> 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.<br /><br /><b> Credit Risks.</b> 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.<br /><br /><b>High Yield Securities Risks.</b> High yield securities, also referred to as &#8220;junk bonds&#8221; or non-investment grade securities, are debt securities rated lower than BBB by Standard &amp; Poor&#8217;s or Baa by Moody&#8217;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 there may be a thin trading market for such securities.<br /><br /><b>Call Risks.</b> If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining.<br /><br /><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility.<br /><br /><b>Asset-Backed/Mortgage-Backed Securities Risks.</b> Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund&#8217;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. 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 securities that are subordinate to another security.<br /><br /><b>Government Obligations Risks.</b> 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. As a result, there is risk that these entities will default on a financial obligation.<br /><br /><b>Foreign Securities Risks.</b> 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&#8217;s total return.<br /><br /><b>Emerging Markets Risks.</b> Investments in emerging markets can involve risks in addition to and greater than those generally associated with investing in more developed foreign markets, which may make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets.<br /><br /><b>Management Risks.</b> TCH&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br /><br /><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies, including exchange-traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses. Fund Performance The bar chart and table show the historical performance of the Fund&#8217;s shares and provide some indication of the risks of investing in the Fund. The bar chart shows how the Fund&#8217;s total returns before taxes have varied from year to year, while the table compares the Fund&#8217;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 www.bmofundsus.com. <b>Class Y&#8212;Annual Total Returns </b>(calendar years 2009-2011) The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; 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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 84% of the average value of its portfolio.

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.<br/><br/><b>Interest Rate Risks. </b>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.<br/><br/><b>Credit Risks. </b>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.<br/><br/><b>Call Risks. </b>If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining.<br/><br/><b>Liquidity Risks. </b>Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility.<br/><br/><b>Asset-Backed/Mortgage-Backed Securities Risks. </b>Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund&#8217;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. 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 securities that are subordinate to another security.<br/><br/><b>Government Obligations Risks.</b> 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. As a result, there is risk that these entities will default on a financial obligation.<br/><br/><b>Management Risks. </b>The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br/><br/><b>Portfolio Turnover Risks. </b>A high portfolio 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. Therefore, you may have higher tax liability. High portfolio turnover also may result in higher transaction costs, which may negatively affect Fund performance.<br/><br/><b>Investments in Other Investment Companies Risks. </b>The Fund may invest in securities issued by other investment companies, including exchange traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund&#8217;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&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013.

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&#8217;s performance. During the period December 29, 2011 (inception date) to August 31, 2012, the Fund&#8217;s portfolio turnover rate (not annualized) was 16% of the average value of its portfolio. Principal Investment Strategies The Fund invests at least 80% of its assets in a diversified portfolio of domestic and foreign high yield, high risk fixed income securities (also referred to as &#8220;junk bonds&#8221;) within the non-investment grade corporate bond market. The Fund&#8217;s sub-adviser seeks to generate excess returns by effectively balancing risk and reward through vigorous asset selection criteria and continuous monitoring of portfolio positions.<br/><br/>The Fund&#8217;s sub-adviser, Monegy, Inc. (&#8220;Monegy&#8221;), follows a disciplined investment approach that combines quantitative investment screening processes with traditional fundamental credit analysis. The portfolio is monitored to determine the risk and reward characteristics of each security, which allows the Fund to generate long term excess returns with lower levels of volatility than The BofA Merrill Lynch US High Yield Constrained Index<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> and The BofA Merrill Lynch US High Yield, BB-B Rated, Constrained Index<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup>. The use of quantitative tools measures credit risk objectively and captures continuous changes in risk and return efficiently. High levels of diversification minimize the portfolio impact of principal losses stemming from unexpected default and other event risks. 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.<br/><br/><b>Call Risks.</b> If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield.

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.<br/><br/><b>Foreign Securities Risks.</b> 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&#8217;s total return.<br/><br/><b>High Yield Securities Risks.</b> High yield securities, also referred to as &#8220;junk bonds&#8221; or non-investment grade securities, are debt securities rated lower than BBB by Standard &amp; Poor&#8217;s or Baa by Moody&#8217;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 there may be a thin trading market for such securities.<br/><br/><b>Income Risks.</b> The Fund&#8217;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.<br/><br/><b>Interest Rate Risks.</b> 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.<br/><br/><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that the Fund may not be able to sell or buy a security or close out an investment contract at a favorable price or time.

Infrequent trading of securities also may lead to an increase in their price volatility.<br/><br/><b>Management Risks.</b> Monegy&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br/><br/><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies, including exchange traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses. 0.006 0.006 0 0 Fund Performance Performance information is not included because the Fund does not have one full calendar year of performance as of the date of this Prospectus. 0.0119 0.0094 Performance information is not included because the Fund does not have one full calendar year of performance as of the date of this Prospectus. 0.0179 0.0154 -0.0079 -0.0069 0.01 0.0085 BMO TCH Emerging Markets Bond Fund Investment Objective: To maximize total return consistent with current income.

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&#8217;s performance. Principal Investment Strategies The Fund invests at least 80% of its assets in debt securities of emerging market governments or of companies located in emerging markets or whose primary business activities or principal trading markets are in emerging markets. Debt securities include sovereign debt instruments and corporate bonds. The Fund&#8217;s sub-adviser, Taplin, Canida &amp; Habacht, LLC (TCH), an affiliate of the Adviser, considers emerging markets to be those markets in any country other than Canada, Luxembourg, the U.S., Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. TCH may make adjustments to the list of emerging market countries from time to time based on economic criteria, market changes, or other factors. <br /><br />Although the Fund will invest primarily in investment grade securities (i.e., rated BBB or Baa, or higher, or unrated and considered by the sub-adviser to be comparable in quality) at the time of purchase, the Fund may invest up to 20% of its assets in debt securities that are below investment grade, also known as high yield securities or &#8220;junk bonds.&#8221; TCH uses macroeconomic, credit, and market analysis to select portfolio securities. Although the Fund expects to maintain an intermediate- to long-term average effective maturity, there are no maturity restrictions on individual holdings or on the overall portfolio. Effective maturity takes into account the possibility that a bond may have prepayments or may be called by the issuer before its stated maturity date. Principal Risks Fund Performance Performance information is not included because the Fund does not have one full calendar year of performance as of the date of this Prospectus. 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. <br /><br /><b>Foreign Securities Risks.</b> 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&#8217;s total return. <br /><br /><b>Emerging Markets Risks.</b> Investments in emerging markets can involve risks in addition to and greater than those generally associated with investing in more developed foreign markets, which may make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets. <br /><br /><b>Sovereign Debt Risk.</b> Sovereign debt instruments are subject to the risk that a governmental entity may be unable to pay interest or repay principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, or political concerns. If a governmental entity defaults on an obligation, the Fund may have limited recourse against the defaulting government and may lose its investment. Financial markets have recently experienced increased volatility due to the uncertainty surrounding the sovereign debt of certain European countries. <br /><br /><b>Interest Rate Risks.</b> 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. <br /><br /><b>Credit Risks.</b> 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.

The Fund invests at least 80% of its assets in obligations issued and/or guaranteed by the U.S. government or by its agencies or instrumentalities and in repurchase agreements secured by such obligations. The securities in which the Fund invests must be rated in one of the two highest short-term rating categories by one or more nationally recognized statistical rating organizations or be determined by the Adviser to be of comparable quality to securities having such ratings (except that U.S. Government securities and shares of other registered money market funds are not subject to this requirement). The Adviser uses a &#8220;bottom-up&#8221; approach, which evaluates debt securities against the context of broader market factors such as the cyclical trend in interest rates, the shape of the yield curve, and debt security supply factors.<br/><br/>The Fund invests in the securities of U.S. government-sponsored entities that are not backed by the full faith and credit of the U.S. government, but are supported through federal loans or other benefits, including the Federal Home Loan Banks (FHLBs), Federal National Mortgage Association (Fannie Mae), and Federal Home Loan Mortgage Corporation (Freddie Mac). The Fund also may invest in the securities of U.S. government-sponsored entities that are supported by the full faith and credit of the U.S. government, such as the Government National Mortgage Association (Ginnie Mae). Finally, the Fund may invest in the securities of governmental entities that have no explicit financial support from the U.S. government, but are regarded as having implied support because the U.S. government sponsors their activities, including the Farm Credit Administration and the Financing Corporation. The Fund invests in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, diversification, and liquidity of investments. 0.0056 0.0031 Principal Risks -0.0011 -0.0011 0 0 December 31, 2013 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.

In addition, the Fund is subject to the following risks.<br/><br/><b>Interest Rate Risks.</b> 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.<br/><br/><b>Credit Risks.</b> 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.<br/><br/><b>Call Risks.</b> If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining.<br/><br/><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility. Additionally, significant redemptions by large investors in the Fund could have a material adverse effect on the Fund&#8217;s other shareholders and the net asset value could be affected by forced selling during periods of high redemption pressures and/or illiquid markets.<br/><br/><b>Government Obligations Risks.</b> 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.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods.

The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: Principal Investment Strategies 2012-09-30 The Fund invests primarily in fixed and floating rate municipal bonds and notes, variable rate demand instruments, and other high-quality, short-term tax-exempt obligations maturing in 397 days or less. Under normal circumstances, the Fund invests its assets so that at least 80% of the annual interest income that the Fund distributes will be exempt from federal income tax, including federal alternative minimum tax (AMT). <br /><br />To maintain principal preservation, the Adviser places a strict emphasis on credit research. Using fundamental analysis, the Adviser develops an approved list of issuers and securities that meet the Adviser&#8217;s standards for minimal credit risk. The Adviser continually monitors the credit risks of all of the Fund&#8217;s portfolio securities on an ongoing basis by reviewing financial data and ratings of nationally recognized statistical rating organizations (NRSROs). The securities in which the Fund invests must be rated in one of the two highest short-term rating categories by one or more NRSROs or be determined by the Adviser to be of comparable quality to securities having such ratings (except that U.S. Government securities and shares of other registered money market funds are not subject to this requirement). The Fund invests in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, diversification, and liquidity of investments. <br /><br />The Fund seeks to enhance yield by taking advantage of favorable changes in interest rates and reducing the effect of unfavorable changes in interest rates. In seeking to achieve this objective, the Adviser targets a dollar-weighted average portfolio maturity of 60 days or less based on its interest rate outlook. The interest rate outlook is developed by analyzing a variety of factors, such as current and expected U.S. economic growth,current and expected interest rates and inflation, and the Federal Reserve Board&#8217;s monetary policy. By developing an interest rate outlook and adjusting the portfolio&#8217;s maturity accordingly, the Adviser seeks to position the Fund to take advantage of yield enhancing opportunities. Principal Risks 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. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Additionally, significant redemptions by large investors in the Fund could have a material adverse effect on the Fund&#8217;s other shareholders and the net asset value could be affected by forced selling during periods of high redemption pressures and/or illiquid markets.<br /><br /><b>Municipal Securities Risks.</b> 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 the interest on an otherwise tax-exempt municipal security may be subject to federal income tax.<br /><br /><b>Management Risks.</b> The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s manager will produce the desired results.<br /><br /><b>Sector Risks.</b> 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&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br /><br /><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses. <b>Class Y&#8212;Annual Total Returns </b>(calendar years 2005-2011) 0.0208 0.0311 0.0335 0.0562 0.0225 Best quarter 0.0077 2009-06-30 0.123 0.0018 Worst quarter 2008-09-30 -0.0496 0.0005 0.0156 0.0083 0.0103 0.0291 0.0475 0.0501 0.0275 0.0044 0.0002 0.0001 <div style="display:none">~ http://www.bmofundsus.com/role/ScheduleShareholderFeesBMOTCHCorporateIncomeFund column period compact * ~</div> <div style="display:none">~ http://www.bmofundsus.com/role/ScheduleAnnualFundOperatingExpensesBMOTCHCorporateIncomeFund column period compact * ~</div> <div style="display:none">~ http://www.bmofundsus.com/role/ScheduleAverageAnnualTotalReturnsTransposedBMOTCHCorporateIncomeFund column period compact * ~</div> 0.0001 0.0017 0.0002 0.0002 Fund Performance The bar chart and table show the historical performance of the Fund&#8217;s shares and provide some indication of the risks of investing in the Fund.

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.<br /><br /><b>Interest Rate Risks.</b> 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.<br /><br /><b>Credit Risks.</b> 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.<br /><br /><b>High Yield Securities Risks.</b> High yield securities, also referred to as &#8220;junk bonds&#8221; or non-investment grade securities, are debt securities rated lower than BBB by Standard &amp; Poor&#8217;s or Baa by Moody&#8217;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 there may be a thin trading market for such securities.<br /><br /><b>Call Risks.</b> If the securities in which the Fund invests are redeemed by the issuer before maturity (or &#8220;called&#8221;), the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund&#8217;s yield. This will most likely happen when interest rates are declining.<br /><br /><b>Liquidity Risks.</b> Liquidity risk refers to the possibility that 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&#8217;s performance. Infrequent trading of securities also may lead to an increase in their price volatility.<br /><br /><b>Asset-Backed/Mortgage-Backed Securities Risks.</b> Asset-backed and mortgage-backed securities are subject to risks of prepayment. The Fund&#8217;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. 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 securities that are subordinate to another security.<br /><br /><b>Government Obligations Risks.</b> 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. As a result, there is risk that these entities will default on a financial obligation.<br /><br /><b>Foreign Securities Risks.</b> 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&#8217;s total return.<br /><br /><b>Management Risks.</b> TCH&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br /><br /><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies, including exchange-traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses.

Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) Example This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund&#8217;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&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: Portfolio Turnover The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; 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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 58% 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 small-sized U.S. companies similar in size to those within the Russell 2000<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> Value Index. These small-sized companies, at the time of purchase, generally have market capitalizations in the range of companies in the Russell 2000<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> Value Index. The largest company by market capitalization in the Russell 2000<sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline">&#174;</sup> Value Index was approximately $3.5 billion as of August 31, 2012 and the median market capitalization of companies in the Index as of the same period was $426.0 million. The Adviser uses a disciplined investment process that identifies companies that it believes have good value relative to their assets, sustainable cash flow, acceptable levels of debt, and potential for improving their business fundamentals. In addition, these companies may have under-appreciated assets, or be involved in company turnarounds or corporate restructurings. 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.<br/><br/><b>Stock Market Risks.</b> 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. If the value of the Fund&#8217;s investments goes down, you may lose money.<br/><br/><b>Sector Risks.</b> Companies with similar characteristics, such as those within the same industry, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Style Risks.</b> 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).<br/><br/><b>Small Company Risks.</b> 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.<br/><br/><b>Management Risks.</b> The Adviser&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results.<br/><br/><b>Investments in Other Investment Companies Risks.</b> The Fund may invest in securities issued by other investment companies, including exchange traded funds. By investing in another investment company, there is a risk that the value of the underlying securities of the investment company may decrease. The Fund will also bear its proportionate share of the other investment company&#8217;s fees and expenses.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund&#8217;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 example reflect the Adviser&#8217;s agreement to waive fees and reimburse expenses through December 31, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: 143 117 553 476 989 858 2201 1933 Portfolio Turnover The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; 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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 83% of the average value of its portfolio. 0.83 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&#8217;s sub-adviser, Lloyd George Management (Europe) Limited (&#8220;LGM(E)&#8221;), considers emerging markets to be those markets in any country other than Canada, Luxembourg, the U.S., Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. LGM(E) may make adjustments to the list of emerging markets countries from time to time based on economic criteria, market changes, or other factors. LGM(E) uses a &#8220;bottom-up,&#8221; fundamental approach in selecting stocks for the Fund&#8217;s portfolio. LGM(E) seeks to identify quality, growth companies typically with dominant industry positions, strong balance sheets, and cash flows to support a sustainable dividend payout. 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.<br/><br/><b>Stock Market Risks.</b> 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. If the value of the Fund&#8217;s investments goes down, you may lose money.<br/><br/><b>Sector Risks.</b> Companies with similar characteristics, such as those within the same industry, may be grouped together in broad categories called sectors. To the extent the Fund invests its assets in a particular sector, the Fund&#8217;s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.<br/><br/><b>Foreign Securities Risks.</b> 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&#8217;s total return.<br/><br/><b>Emerging Markets Risks.</b> Investments in emerging markets can involve risks in addition to and greater than those generally associated with investing in more developed foreign markets, which may make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets.<br/><br/><b>Company Size Risks.</b> 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.<br/><br/><b>Management Risks.</b> LGM(E)&#8217;s judgments about the attractiveness, value, and potential appreciation of the Fund&#8217;s investments may prove to be incorrect. Accordingly, no guarantee exists that the investment techniques used by the Fund&#8217;s managers will produce the desired results. 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.
