Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund ("Shares"). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table or the example below.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

Management Fees			0.59%
Other Expenses(1)			0.00%
Total Annual Fund Operating Expenses (2)			0.59%

(1)Based on estimated amounts.

(2)The investment management agreement (the "Management Agreement") between the Fund and Principal Global Investors, LLC ("PGI") provides that, for the duration of the Management Agreement, PGI will pay all operating expenses of the Fund, except for the Management Fee, payments made under the Fund's Rule 12b-1 plan (if or when such fees are imposed), brokerage commissions and other expenses connected to the execution of portfolio transactions, interest expense, taxes, acquired fund fees and expenses, litigation expenses, and tax reclaim recovery expenses and other extraordinary expenses.

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 ends of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

			1 year			3 years
Principal Finisterre Emerging Markets Diversified Income ETF			$60			$189

Portfolio Turnover

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's performance. This Fund is new and does not have a portfolio turnover rate to disclose.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in emerging markets securities. The Fund invests in fixed-income securities, including those issued by sovereign, quasi-sovereign, and corporate issuers. The Fund also invests in fixed-income securities, including convertible bonds, credit- and index-linked securities, non-registered and restricted securities (including those issued in reliance on Rule 144A and Regulation S), securities issued by distressed or bankrupt issuers, and securities issued by the U.S government or U.S. government-sponsored enterprises.

Emerging markets are generally defined to include all countries except Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom, and the United States. The Fund considers a security to be tied economically to an emerging market if one or more of the following criteria is present: (i) the issuer or guarantor of the security has its principal place of business or principal office in an emerging market; (ii) the principal trading market for the security is in an emerging market; (iv) the issuer or guarantor of the security derives a majority of its revenue from emerging markets; or (iv) the currency of settlement of the security is the currency of an emerging market. Emerging markets include frontier markets.

The Fund invests, without limitation, in high yield securities (also known as "junk") rated at the time of purchase Ba1 or lower by Moody's Ratings, and BB+ or lower by S&P Global Ratings ("S&P Global"). If the security has been rated by only one of the rating agencies, that rating will determine the security's rating; if the security is rated differently by the rating agencies, the highest rating will be used; and if the security has not been rated by either of the rating agencies, those selecting such investments will determine the security's quality. The Fund's holdings range in maturity from overnight to 30 years or more and are not subject to any minimum credit rating standard.

The Fund's investment process focuses primarily on market level analysis of global markets and political developments and their impact on individual countries and companies in emerging markets. The Fund uses a top-down portfolio construction process, blending both fundamental and technical considerations. The investment strategy provides considerable flexibility to invest in various asset classes, capital structures, maturities, and currencies.

The Fund uses derivatives to enhance return and to hedge and manage investment risks. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Specifically, the Fund uses currency contracts, forward contracts, futures, options, and swaps. The Fund invests in cash and cash equivalents to support certain of these investments, as well as for other purposes.

Principal Risks

The value of your investment in the Fund changes with the value of the Fund's investments. Many factors affect that value, and it is possible to lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund are listed below in alphabetical order and not in order of significance.

Active Management Risk. The Fund's investments are actively managed by the investment team and do not track an index. Consequently, there is no guarantee that the investment techniques, analyses, or judgments that the Fund's investment advisor and/or sub-advisor applies in making investment decisions for the Fund will produce the intended outcome or that the investments the advisor selects for the Fund will perform as well as other securities that were not selected for the Fund. The Fund may not achieve its investment objective, and it is not intended to be a complete investment program.

Counterparty Risk. Counterparty risk is the risk that the counterparty to a contract or other obligation will be unable or unwilling to honor its obligations.

2 of 5

Derivatives Risk. Derivatives may not move in the direction anticipated by the portfolio manager. Transactions in derivatives may increase volatility, cause the liquidation of portfolio positions when not advantageous to do so, and result in disproportionate losses that may be substantially greater than a fund's initial investment.

•Currency Contracts. Derivatives related to currency contracts, which include futures, spot contracts, and swaps, involve the specific risk of government action that would restrict the ability of the Fund to deliver or receive currency.

•Forward Contracts, Futures, and Swaps. Forward contracts, futures, and swaps involve specific risks, including: the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward contract, future, or swap; possible lack of a liquid secondary market for a forward contract, future, or swap and the resulting inability to close a forward contract, future, or swap when desired; counterparty risk; and if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements.

•Options. Options involve specific risks, including: the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the options; counterparty risk; difference in trading hours for the options markets and the markets for the underlying securities (rate movements can take place in the underlying markets that cannot be reflected in the options markets); and an insufficient liquid secondary market for particular options.

Distressed Investments Risk. A fund's investment in instruments involving loans, loan participations, bonds, notes, non-performing and sub-performing mortgage loans, many of which are not publicly traded, may involve a substantial degree of risk for the following reasons. These instruments may become illiquid and the prices of such instruments may be extremely volatile. Valuing such instruments may be difficult and a fund may lose all of its investment, or it may be required to accept cash or securities with a value less than the fund's original investment. Issuers of distressed securities are typically in a weak financial condition and may default, in which case the fund may lose its entire investment.

Emerging Markets Risk. Investments in emerging markets may have more risk than those in developed markets because the emerging markets are less developed and more illiquid. Emerging markets can also be subject to increased social, economic, regulatory, and political uncertainties and can be extremely volatile. The U.S. Securities and Exchange Commission, the U.S. Department of Justice, and other U.S. authorities may be limited in their ability to pursue bad actors in emerging markets, including with respect to fraud.

•Frontier Markets Risk. Frontier markets are emerging markets, but generally have small economies or less mature capital markets than more developed emerging markets, and, as a result, the risks of investing in emerging markets are magnified in frontier markets. Frontier markets typically have low trading volumes and the potential for extreme price volatility and illiquidity.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate, credit quality, and liquidity risks. The market value of fixed-income securities generally declines when interest rates rise, and increased interest rates may adversely affect the liquidity of certain fixed-income securities. Moreover, an issuer of fixed-income securities could default on its payment obligations due to increased interest rates or for other reasons.

Floating and Variable Rate Securities Risk. The market prices of securities with variable and floating interest rates are generally less sensitive to interest rate changes than are the market prices of securities of fixed interest rates. Floating and variable rate securities may decline in value if market interest rates or interest rates paid by them do not move as expected. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund's ability to sell the securities at any given time.

Foreign Currency Risk. Risks of investing in securities denominated in, or that trade in, foreign (non-U.S.) currencies include changes in foreign exchange rates and foreign exchange restrictions.

Foreign Securities Risk. The risks of foreign securities include loss of value as a result of: political or economic instability; nationalization, expropriation, or confiscatory taxation; settlement delays; and limited government regulation (including less stringent reporting, accounting, and disclosure standards than are required of U.S. companies).

Hedging Risk. A fund that implements a hedging strategy using derivatives and/or securities could expose the fund to the risk that can arise when a change in the value of a hedge does not match a change in the value of the asset it hedges. In other words, the change in value of the hedge could move in a direction that does not match the change in value of the underlying asset, resulting in a risk of loss to the Fund.

3 of 5

High Yield Securities Risk. High yield fixed-income securities (commonly referred to as "junk bonds") are subject to greater credit quality risk than higher rated fixed-income securities and should be considered speculative.

Leverage Risk. Leverage created by borrowing or certain types of transactions or investments may impair the Fund's liquidity, cause it to liquidate positions at an unfavorable time, increase volatility of the Fund's net asset value, or diminish the Fund's performance.

Market Trading Risks. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, and disruption to the activities of market makers, authorized participants, or other participants and in the creation/redemption process of the Fund. Because securities held by the Fund may trade on, or have exposure to, foreign exchanges that are closed when the Fund's primary listing exchange is open, there are likely to be deviations between the last quote from the securities closed foreign market and the value of such security during the Fund's domestic trading day, which in turn may result in differences between the market price of the Fund's shares and the underlying value of those shares. ANY OF THESE FACTORS MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Portfolio Duration Risk. Portfolio duration is a measure of the expected life of a fixed-income security and its sensitivity to changes in interest rates. The longer a fund's average portfolio duration, the more sensitive the fund will be to changes in interest rates, which means funds with longer average portfolio durations may be more volatile than those with shorter durations.

Redemption and Large Transaction Risk. Ownership of the Fund's shares may be concentrated in one or a few large investors (such as funds of funds, institutional investors, and asset allocation programs) that may sell or purchase Fund shares in large quantities on the secondary market. These secondary market transactions may cause authorized participants to increase their purchases and redemptions of creation units from the Fund. Redemptions by large shareholders could have a significant negative impact on the Fund, including on the Fund's liquidity. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund's exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

Sovereign Debt Risk. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity's debt position in relation to the economy, or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.

U.S. Government Securities Risk. Yields available from U.S. government securities are generally lower than yields from many other fixed-income securities. The value of U.S. government securities may be adversely impacted by changes in interest rates, changes in the credit rating of the U.S. government, or a default by the U.S. government.

Performance

No performance information is shown because the Fund has not yet had a calendar year of performance. The Bloomberg Global Aggregate Index is the Fund's primary broad-based securities market index. The JPM EMBI Equal Weighted Index is included as an additional index for the Fund as it shows how the Fund's performance compares with the returns of an index of funds with similar investment objectives. Performance information provides an indication of the risks of investing in the Fund. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Purchase and Sale of Fund Shares

The Fund issues and redeems Shares at net asset value ("NAV") only with authorized participants ("APs") who have entered into agreements with the Fund's distributor in exchange for the deposit or delivery of a basket of securities that the Fund specifies each day. Except when aggregated in creation units, the Shares are not redeemable securities of the Fund. Typically, the basket of assets will be made up of securities but may include a cash component. (See "Purchase and Redemption of Creation Units" in the Statement of Additional Information for more information.)

Shares of the Fund are listed for trading on NYSE Arca, Inc. Individual Shares may only be bought and sold in the secondary market through a broker or dealer at a market price. Because Shares trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares on the secondary market (the bid-ask spread).

You can access recent information, including information on the Fund's net asset value, market price, premiums and discounts, and bid-ask spreads at www.PrincipalAM.com.

Tax Information

The Fund's distributions you receive are generally subject to federal income tax as ordinary income or capital gain and may also be subject to state and local taxes, unless you are tax-exempt or your account is tax-deferred in which case your distributions would be taxed when withdrawn from the tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary, the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
