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 Government Money Market Fund (USD $)	Class Y	Class I
1 Year	46	20
3 Years	166	86
5 Years	297	159
10 Years	680	371

Principal Investment Strategies

The Fund invests its assets in high quality, short-term money market instruments and repurchase agreements. 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. The Adviser uses a "bottom-up" 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.

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.

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. In addition, the Fund is subject to the following risks.

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

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

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

Liquidity Risks. 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's performance. Infrequent trading of securities also may lead to an increase in their price volatility.

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

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 manager will produce the desired results.
