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’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’s agreement to waive fees and reimburse expenses through December 31, 2014. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Expense Example BMO Small-Cap Core Fund (USD $)	Class Y	Class I
1 Year	117	92
3 Years	533	455

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.

Principal Investment Strategies

The Fund invests at least 80% of its assets in a broadly diversified portfolio of common stocks of small-cap U.S. companies similar in size to those within the Russell 2000^® Index. These small-cap companies, at the time of purchase, generally have market capitalizations in the range of companies in the Russell 2000^® Index. The largest company by market capitalization in the Russell 2000^® Index was approximately $5.05 billion as of October 31, 2013, and the median market capitalization of companies in the Index as of the same period was $666 million.

The Fund pursues its investment objective in the small-cap sector by investing in a select group of small-cap companies believed to be undervalued relative to their future growth potential. The Fund is designed to be a “core” fund that seeks to combine both value and growth characteristics within the small-cap universe. The investment strategy focuses on company fundamentals by using a disciplined quantitative process to identify companies that, in the Adviser’s opinion, exhibit improving investor interest, have a sustainable competitive advantage, have low financial risk, and will be able to outperform the market over full market cycles. The quantitative process uses a multi-factor risk/return investment model based on internal research and extensive academic studies to select investments for the Fund. The model then ranks each stock in order of attractiveness. The Adviser periodically modifies the investment model based upon its fundamental analysis of the output of the model and the designated risk parameters.

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.

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. If the value of the Fund’s investments goes down, you may lose money.

Sector Risks. 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’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

Core Style Investing Risks. The returns on “core” securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund’s investments will vary and at times may be lower or higher than that of other types of investments.

Small-Cap Company 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.

Information Risks. When the quantitative models (“Models”) and information and data (“Data”) used in managing the Fund prove to be incorrect or incomplete, any investment decisions made in reliance on the Models and Data may not produce the desired results and the Fund may realize losses. The success of Models that are predictive in nature is dependent largely upon the accuracy and reliability of the supplied historical data. All Models are susceptible to input errors that may cause the resulting information to be incorrect.

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.

Quantitative Model Investment Risks. The success of a quantitative investment model depends on the analyses and assessments that were used in developing such model. Incorrect analyses and assessments or inaccurate or incomplete data would adversely affect performance. There can be no assurance that the model will enable to the Fund to achieve its investment objective.

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.

[1] "Other Expenses" are based on estimated amounts for the Fund's current fiscal year because it is a new fund.

[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 1.15% for Class Y and 0.90% for Class I through December 31, 2014. This expense limitation agreement may not be terminated prior to December 31, 2014 without the consent of the Fund's Board of Directors unless terminated due to the termination of the investment advisory agreement.
