Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Investor Class shares of the Fund.

Shareholder Fees (fees paid directly from your investment)
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None
Redemption Fee (as a percentage of amount redeemed, for shares held less than 30 days)	2.00%
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.40%
Distribution (12b-1) Fees	None
Other Expenses	0.52%
Total Annual Fund Operating Expenses	0.92%
Fee Waiver and Expense Reimbursement(1)	0.12%
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement(1)	0.80%

(1) M&I Investment Management Corp. (Adviser) has agreed to waive or reduce its investment advisory fee or reimburse expenses to the extent necessary to prevent Investor 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 a Fund’s business) from exceeding 0.80% through December 31, 2010. The Adviser may not terminate this arrangement prior to December 31, 2010 unless the investment advisory agreement is terminated.

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/or reimburse expenses through December 31, 2010. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$	82
3 Years	$	281
5 Years	$	498
10 Years	$	1,120

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 445% of the average value of its portfolio.

Principal Investment Strategies

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’s strategy for achieving total return is to adjust the Fund’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.

Principal Risks

The Fund cannot assure that it will achieve its investment goal. An investment in the Fund is not a deposit of M&I Marshall & Ilsley Bank 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.

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. Bonds rated BBB or Baa have speculative characteristics.

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

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.

Asset-Backed/Mortgage-Backed Securities Risks. Asset-backed and mortgage-backed securities are subject to risks of prepayment. A Fund’s yield will be reduced if cash from prepaid securities is reinvested in securities with lower interest rates. The risk of prepayment also may decrease the value of mortgage-backed securities. Asset-backed securities may have a higher level of default and recovery risk than mortgage-backed securities. 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.

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.

After-tax returns are calculated using the highest historical individual marginal federal income tax rates and do not reflect the effect of any applicable state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors holding shares through tax-deferred programs, such as IRAs or 401(k) plans. Return After Taxes on Distributions and Sale of Fund Shares may be higher than Return Before Taxes when a net capital loss occurs upon the redemption of Fund shares.

The Fund’s returns reflect fee waivers and/or expense reimbursements that were in effect during one or more of the periods presented. Absent such fee waivers and/or expense reimbursements, the returns would have been lower.
