The objective of the Fund is also to provide a current income yield of at least 25% greater than that of the</font> S&amp;P 500 Index<font style="DISPLAY: inline; COLOR: #231f20">, although there can be no assurance that this objective will be met.</font></font> </div> Principal Investment Strategies <div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"> <font style="DISPLAY: inline; FONT-FAMILY: times new roman; FONT-SIZE: 10pt">The Fund emphasizes investments in common stock and other securities convertible into common stock as well as fixed income securities such as corporate bonds and United States government securities. In selecting securities for the Fund, the Fund&#8217;s investment adviser, Mairs and Power, Inc. (the Adviser) gives preference to equity holdings in high quality companies, which are characterized by earnings that are reasonably predictable, have a return on equity that is above average, hold market dominance and have financial strength. Some emphasis is given to companies generally located in the Upper Midwest region of the United States and to small and midcap companies (the Adviser defines a small company as a company with less than two billion dollars in market capitalization at the time of initial purchase, and a midcap company has a market capitalization between two and ten billion dollars at the time of initial purchase). The Adviser also gives preference to higher rated investment-grade fixed income securities (rated Baa or better by Moody&#8217;s Investors Service). Lower rated convertible and non-convertible debt securities may be purchased if, in the opinion of the Adviser, the potential rewards outweigh the incremental risks. The Fund may invest in mortgage-backed securities. The Fund may also invest in ADRs and other foreign securities. The Fund seeks to keep its assets reasonably fully invested, to maintain modest portfolio turnover rates and to moderate risk by investing in a diversified portfolio of equity and fixed income securities.</font> </div> <br/><div style="TEXT-INDENT: 0pt; DISPLAY: block"> The Fund may sell its portfolio securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities. </div> Portfolio Turnover <div> The Fund pays 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<font color="#231F20">&#8217;</font>s performance.

When interest rates rise, the value of a fixed-rate debt security generally decreases. When interest rates decline, the value of a fixed-rate debt security generally increases. Generally, a debt security with a longer maturity will have greater price volatility as a result of interest rate changes than a debt security with a shorter maturity.

Securities issued by the United States government generally are viewed as carrying minimal credit risk. Securities issued by private entities and governmental entities not backed by the full faith and credit of the United States are subject to higher levels of credit risk.

Mairs & Power Small Cap Fund MSCFX Investment Objective <div> The objective of the Mairs &amp; Power Small Cap Fund (the Fund) is to seek above-average, long-term appreciation. </div> Principal Investment Strategies <div> The Fund normally will invest at least 80% of its net assets (including borrowings for investment purposes) in common stocks issued by small cap companies. For this purpose, small cap companies are defined as companies whose market capitalization at the time of purchase come within the range represented by companies in the S&amp;P SmallCap 600 Index as of December 31 of the preceding year. The S&amp;P SmallCap 600 Index is a widely used benchmark for small cap performance and is rebalanced continuously. As of December 31, 2012, the market capitalization ranges for the S&amp;P SmallCap 600 Index were approximately $61 million to $4.0 billion. </div> <br/><div style="TEXT-INDENT: 0pt; DISPLAY: block"> In selecting stocks, the Fund&#8217;s investment adviser, Mairs and Power, Inc. (the Adviser) gives preference to companies with attractive business niches, strong competitive positions, and the potential to grow revenues, earnings and cash flows consistently over the long-term. Capable management with a track record of prudent capital deployment is also an important consideration. Some emphasis is given to companies generally located in the Upper Midwest region of the United States. The Fund also may invest in common stocks issued by companies with market capitalizations above the range of the S&amp;P SmallCap 600 Index. The Fund may invest up to 25% of its total assets in securities of foreign issuers which are listed on a United States stock exchange or are represented by American Depositary Receipts (ADRs). The Fund seeks to keep its assets reasonably fully invested, to maintain modest portfolio turnover rates, and to mitigate risk by investing in a diversified portfolio of securities. </div> <br/><div> <br /> The Fund may sell its portfolio securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities. </div> Portfolio Turnover <div> The Fund pays 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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 6.93% of the average value of its portfolio. </div> 0.0693 Expense Example <div> This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and you 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&#8217;s operating expenses remain the same.</div> 128 399 799 1917 ~ http://usbank.com/20130903/role/ScheduleExpenseExampleTransposed20010 column dei_LegalEntityAxis compact ck0001521353_S000033564Member row primary compact * ~ Although your actual costs may be higher or lower, based on these assumptions, your costs would be: Fees and Expenses of the Fund <div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"> <font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.</font> </div> -0.0100 0.0090 0.0084 0.0174 -0.0048 0.0126 ~ http://usbank.com/20130903/role/ScheduleShareholderFees20008 column dei_LegalEntityAxis compact ck0001521353_S000033564Member row primary compact * ~ ~ http://usbank.com/20130903/role/ScheduleAnnualFundOperatingExpenses20009 column dei_LegalEntityAxis compact ck0001521353_S000033564Member row primary compact * ~ The Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the Fund in the table above differs from the Ratio of Expenses to Average Net Assets found within the "Financial Highlights" section of the prospectus because the audited information in the "Financial Highlights" reflects the operating expenses and does not include indirect expenses such as Acquired Fund Fees and Expenses, which was 0.01% for the fiscal year ended December 31, 2012.

In selecting securities for the Fund, the Fund&#8217;s investment adviser, Mairs and Power, Inc. (the Adviser) gives preference to equity holdings in high quality companies, which are characterized by earnings that are reasonably predictable, have a return on equity that is above average, hold market dominance and have financial strength. Some emphasis is given to companies generally located in the Upper Midwest region of the United States and to small and midcap companies (the Adviser defines a small company as a company with less than two billion dollars in market capitalization at the time of initial purchase, and a midcap company has a market capitalization between two and ten billion dollars at the time of initial purchase). The Adviser also gives preference to higher rated investment-grade fixed income securities (rated Baa or better by Moody&#8217;s Investors Service). Lower rated convertible and non-convertible debt securities may be purchased if, in the opinion of the Adviser, the potential rewards outweigh the incremental risks. The Fund may invest in mortgage-backed securities. The Fund may also invest in ADRs and other foreign securities.
