1Performance shown includes the reinvestment of dividend and capital gain distributions, but does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

Minnesota Municipal Bond ETF



Board Leadership Structure

The Board has structured itself in a manner that it believes allows it to effectively perform its oversight function.

The Board of Trustees is composed of six Independent Trustees and one Trustee who is an “interested person” of the Trust (the “Interested Trustee”).

Dr. Michael D. Akers
Mr. Gary A. Drska
Vincent P. Lyles
Erik K. Olstein
Lisa Zúñiga Ramírez
Gregory M. Wesley
Mr. Joseph C. Neuberger, Interested Trustee

Accordingly, 85% of the members of the Board are Independent Trustees, Trustees who are not affiliated with the Adviser or its affiliates, or any other investment adviser or other service provider to the Trust or any underlying fund. The Board of Trustees has established three standing committees, an Audit Committee, a Nominating Committee and a Valuation Committee. Each of the Audit Committee and the Nominating Committee is comprised entirely of Independent Trustees. The Independent Trustees have engaged their own independent counsel to advise them on matters relating to their responsibilities in connection with the Trust. More information is available in the Statement of Additional Information (SAI).

Investments involve risk. The Fund is designed for long-term investors. Principal loss is possible.

Mairs & Power Minnesota Municipal Bond ETF has the same risks as the underlying securities traded on the exchange throughout the day. Redemptions are limited and often commissions are charged on every trade.

The Fund may trade at a premium or discount to NAV. Shareholders may pay more than NAV when they buy Fund shares and receive less than NAV when they sell those shares, because shares are bought and sold at current market prices. The data presented represents past performance and cannot be used to predict future results.

Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities. Investment by the Fund in lower-rated and non-rated securities presents a greater risk of loss to principal and interest than higher-rated securities. Because the Fund invests substantially in Minnesota municipal instruments, it is more exposed to the impact of negative political, economic and legislative factors within Minnesota than a fund that invests more widely. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. The Fund is also subject to risks associated with investments in the municipal bond market, municipal mortgage backed securities, and other investment companies. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors have a limited track record on which to base their investment decision. There is also a risk that the Fund will not grow to or maintain an economically viable size, in which case it could ultimately liquidate without shareholder approval.

Some of the Fund investments may be subject to AMT. Although the Fund is exempt from federal tax, you may owe taxes on any capital gains realized through the fund's trading or through your own redemption of shares.For some investors, a portion of the fund's income may be subject to state and local taxes.

Monthly income distributions are not guaranteed.


*Mairs & Power uses lower of the S&P or Moody's ratings and chooses to display credit ratings using S&P’s rating convention, although the rating itself might be sourced from another Nationally Recognized Statistical Rating Agency. The ratings apply to the credit worthiness of the issuers of the underlying securities and not to the fund itself. Ratings are expressed as letters ranging from ‘AAA’, which is the highest grade, to ‘D’, which is the lowest grade. In limited situations when the rating agency has not issued a formal rating, the rating agency will classify the security as unrated.

3Premium/Discount If the price of the ETF is trading above its NAV, the ETF is said to be trading at a "premium." Conversely, if the price of the ETF is trading below its NAV, the ETF is said to be trading at a "discount." In relatively calm markets, ETF prices and NAV generally stay close.

430 Day Median Spread % a calculation of Fund’s median bid-ask spread, expressed as a percentage rounded to the nearest hundredth, computed by: identifying the Fund’s national best bid and national best offer as of the end of each 10 second interval during each trading day of the last 30 calendar days; dividing the difference between each such bid and offer by the midpoint of the national best bid and national best offer; and identifying the median of those values.

5Cboe Global Markets

6NAV/Price The ETF market price is the price at which shares in the ETF can be bought or sold on the exchanges during trading hours. The net asset value (NAV) of an ETF represents the value of each share's portion of the fund's underlying assets and cash at the end of the trading day.

730-Day SEC Yield A fund's 30-Day SEC Yield is a calculation based on the 30 days ending on the last day of the previous month. The yield figure reflects the dividends and interest earned during the period, after the deduction of the fund's expenses.

8Wtd. Average Maturity The average time it takes for securities in a portfolio to mature, weighted in proportion to the dollar amount that is invested in the portfolio. Weighted average maturity measures the sensitivity of fixed-income portfolios to interest rate changes.

9Net Yield to Worst at NAV is the yield to expected payout of principal given current market pricing, net of current management fees.

10Duration to Worst is a measure of weighted average expected cash flows based on expected maturity of bonds. This measure can indicate interest rate sensitivity as a higher duration to worst indicates greater sensitivity to moves in interest rates and a lower duration to worst indicates relatively lower sensitivity to a move in interest rates.

11Sales Charge: Shares of the Mairs & Power Minnesota Municipal Bond ETF can be purchased through financial advisors or are available through online brokerage firms. These firms may charge commissions and sales charges.
