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-, five-, and ten-year examples reflect the Adviser's agreement to waive fees and reimburse expenses through July 6, 2013. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Expense Example - BMO Small-Cap Growth Fund (USD $)	Class Y	Class I
1 Year	147	121
3 Years	460	382
5 Years	796	663
10 Years	1,745	1,464

Portfolio Turnover

The Fund incurs transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 101% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in common stocks of small-sized U.S. companies similar in size to those within the Russell 2000^® Growth Index. These small-sized companies, at the time of purchase, generally have market capitalizations in the range of companies in the Russell 2000^® Growth Index. The largest company by market capitalization in the Russell 2000^® Growth Index was approximately $3.2 billion as of August 31, 2011 and the median market capitalization of companies in the Index as of the same period was $540 million. The Adviser selects stocks of companies with growth characteristics, including companies with above-average earnings growth potential and companies where significant changes are taking place, such as new products, services or methods of distribution, or overall business restructuring.

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.

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

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

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

Fund Performance

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

[2] M&I Investment 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 1.44% for Class Y and 1.19% for Class I through July 6, 2013. The Adviser may not terminate this arrangement prior to July 6, 2013 unless the investment advisory agreement is terminated.
