(1) Acquired Fund Fees and Expenses represent the pro rata expense indirectly incurred by the Fund as a result of its investment in other investment companies (each, an “Acquired Fund”). Total Annual Fund Operating Expenses shown will not correlate to the Fund’s ratios of expenses to average net assets appearing in the Financial Highlights tables, which do not include Acquired Fund Fees and Expenses.

(2) 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 the Advisor Class total annual operating expenses (excluding interest, taxes, brokerage commissions, other investment-related costs, extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of a Fund’s business, and Acquired Fund Fees and Expenses) 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	$	459
3 Years	$	849
5 Years	$	1,265
10 Years	$	2,422

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 period December 23, 2008 (commencement of operations) to August 31, 2009, the Fund’s portfolio turnover rate (not annualized) was 38% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its assets in corporate debt securities, including convertible debt securities. Although the Fund will invest primarily in U.S. dollar denominated 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, 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 “junk bonds,” and in foreign debt securities. The Fund also may invest in U.S. government securities and asset-backed and mortgage-backed securities.

The Fund’s sub-adviser is Taplin, Canida & Habacht, LLC (TCH), an affiliate of the Adviser. 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 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.

Foreign Securities Risks. Investing in foreign securities involves 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’s total return.

High Yield Securities Risks. High yield securities tend to be more sensitive to economic conditions than are higher-rated securities and generally involve more credit risk than securities in the higher-rated categories. 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.

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.
