TABLE OF CONTENTS

PRINCIPAL EDGE ACTIVE INCOME ETF

Objective : The Fund seeks to provide current income.

Fees and Expenses of the Fund:

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund ("Shares"). Investors may pay brokerage commissions on their purchases and sales of Shares, 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)

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 remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 is a new Fund and does not yet 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, its assets in investment grade and non-investment grade fixed income securities and in equity securities. In pursuing its strategies, the Fund invests in a diversified portfolio of a broad range of instruments, and it may carry out its investment strategies through active management or purchases of ETFs or other investment company shares. The Fund’s Sub-Advisor actively and tactically allocates the Fund’s assets among fixed income securities and equity securities in an effort to take advantage of changing economic conditions that the Sub-Advisor believes favors one asset class over another. Based on the analysis of various economic indicators, the Sub-Advisor will increase the allocation to the asset class that the Sub-Advisor believes will have a higher probability of achieving the Fund’s objective of providing current income.

Fixed Income. A portion of the Fund's net assets will be invested in a diversified portfolio of investment grade and non-investment grade fixed income securities issued by U.S., supranational and non-U.S. issuers (including issuers located in emerging markets) including investments in convertible bonds, inverse floating rate instruments, municipal bonds, U.S. government and agency securities, asset-backed securities and mortgage-backed securities (including commercial mortgage-backed securities). “Investment grade” securities are rated BBB- or higher by S&P or Baa3 or higher by Moody's or, if unrated, of comparable quality in the opinion of the Sub-Advisor. “Non-investment grade” securities are rated Ba1 or lower by Moody’s and BB+ or lower by S&P. If the security has been rated by only one of those agencies, that rating will determine whether the security is below investment grade. If the security has not been rated by either of those agencies, the Sub-Advisor will determine whether the security is of a quality comparable to those rated below investment grade.

Equity Securities. A portion of the Fund's net assets will be invested in a diversified portfolio of equity securities issued by companies located in the U.S. and/or foreign countries, including emerging markets, which trade on a U.S.

or foreign exchange. The equity securities will be common stocks and preferred stocks as well as master limited partnerships (“MLPs”) and real estate investment trusts (“REITs”).

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, in alphabetical order, are:

Active Trading Risk. A fund that has a portfolio turnover rate over 100% is considered actively traded. Actively trading portfolio securities may accelerate realization of taxable gains and losses, lower fund performance and may result in high portfolio turnover rates and increased brokerage costs.

Asset Allocation Risk. A fund's selection and weighting of asset classes may cause it to underperform other funds with a similar investment objective.

Convertible Securities Risk. Convertible securities can be bonds, notes, debentures, preferred stock or other securities which are convertible into common stock. Convertible securities are subject to both the credit and interest rate risks associated with fixed income securities and to the stock market risk associated with equity securities.

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.

Emerging Market Risk. Investments in emerging market countries may have more risk than those in developed market countries because the emerging markets are less developed and more illiquid. Emerging market countries can also be subject to increased social, economic, regulatory, and political uncertainties and can be extremely volatile.

Equity Securities Risk. Equity securities (common, convertible preferred stocks and other securities whose values are tied to the price of stocks, such as rights, warrants and convertible debt securities) could decline in value if the issuer's financial condition declines or in response to overall market and economic conditions. A fund's principal market segment(s), such as large cap, mid cap or small cap stocks, or growth or value stocks, may underperform other market segments or the equity markets as a whole. Investments in smaller companies and mid-size companies may involve greater risk and price volatility than investments in larger, more mature companies.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit quality risk. The market value of fixed-income securities generally declines when interest rates rise, and an issuer of fixed-income securities could default on its payment obligations.

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).

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.

Inverse Floating Rate Investments. Inverse floating rate investments are extremely sensitive to changes in interest rates and in some cases their market value may be extremely volatile.

Market Trading Risks. The risks that the Fund faces because its shares are listed on a securities exchange, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Master Limited Partnership ("MLP") Risk. MLPs are publicly-traded limited partnership interests or units. An MLP that invests in a particular industry (e.g., oil and gas) will be harmed by detrimental economic events within that industry. As partnerships, MLPs may be subject to less regulation (and less protection for investors) under state laws than corporations. In addition, MLPs may be subject to state taxation in certain jurisdictions, which may reduce the amount of income an MLP pays to its investors.

Municipal Securities Risk. Principal and interest payments on municipal securities may not be guaranteed by the issuing body and may be payable only from a particular source. That source may not perform as expected and payment obligations may not be made or made on time.

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.

Preferred Securities Risk. Preferred securities are securities with a lower priority claim on assets or earnings than bonds and other debt instruments in a company's capital structure, and therefore can be subject to greater credit and liquidation risk than more senior debt instruments. In addition, preferred securities are subject to other risks, such as limited or no voting rights, deferring or skipping distributions, interest rate risk, and redeeming the security prior to the stated maturity date.

Prepayment Risk. Unscheduled prepayments on mortgage-backed and asset-backed securities may have to be reinvested at lower rates. A reduction in prepayments may increase the effective maturities of these securities, exposing them to the risk of decline in market value over time (extension risk).

Real Estate Investment Trusts (“REITs”) Risk. A REIT could fail to qualify for tax-free pass-through of income under the Internal Revenue Code, and fund shareholders will indirectly bear their proportionate share of the expenses of REITs in which the fund invests.

Real Estate Securities Risk. Real estate securities are subject to the risks associated with direct ownership of real estate, including declines in value, adverse economic conditions, increases in expenses, regulatory changes and environmental problems. Investing in securities of companies in the real estate industry, subjects a fund to the special risks associated with the real estate market including factors such as loss to casualty or condemnation, changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use and rents, and the management skill and creditworthiness of the issuer.

Risk of Investing in Exchange-Traded Funds ("ETFs"). An ETF is subject to the risks associated with direct ownership of the securities comprising the index on which the ETF is based. Fund shareholders indirectly bear their proportionate share of the expenses of the ETFs in which the fund invests.

Risk of Investing in Investment Companies. Fund shareholders bear indirectly their proportionate share of the expenses of other investment companies in which the fund invests.

U.S. Government Securities Risk. Yields available from U.S. government securities are generally lower than yields from many other fixed-income securities.

U.S. Government Sponsored Securities Risk. Securities issued by U.S. government-sponsored or -chartered enterprises such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, and the Federal Home Loan Banks are not issued or guaranteed by the U.S. Treasury.

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 and only in blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"), or multiples thereof ("Creation Unit Aggregations"), in exchange for the deposit or delivery of a basket of assets that the Fund specifies each day. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares of the Fund may be purchased and sold only on a national securities exchange through brokers. Shares of the Fund are expected to be listed for trading on NYSE Arca, Inc. ("NYSE Arca") and because the Shares

will 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).

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 (such as a bank, insurance company, investment adviser, etc.), 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.

ADDITIONAL INFORMATION ABOUT INVESTMENT STRATEGIES AND RISKS

The Fund’s investment objective is described in the summary section for the Fund. The summary section also describes the Fund’s principal investment strategies, including the types of securities in which the Fund invests, and the principal risks of investing in the Fund. The principal investment strategies are not the only investment strategies available to the Fund, but they are the ones the Fund primarily uses to achieve its investment objective.

The Board of Trustees may change the Fund's objective or the investment strategies without a shareholder vote if it determines such a change is in the best interests of the Fund. If there is a material change to the Fund's investment objective or investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will meet its objective.

The investment strategies identified in this section provide specific information about the Fund, but there are some general principles the Sub-Advisors apply in making investment decisions. When making decisions about whether to buy or sell equity securities, the Sub-Advisors may consider, among other things, a company’s strength in fundamentals, its potential for earnings growth over time, its ability to navigate certain macroeconomic environments, and the current price of its securities relative to their perceived worth and relative to others in its industry. When making decisions about whether to buy or sell fixed-income investments, the Sub-Advisors may consider, among other things, the strength of certain sectors of the fixed-income market relative to others, interest rates, the macroeconomic backdrop, the balance between supply and demand for certain asset classes, other general market conditions, and the credit quality of individual issuers.

The Fund is designed to be a portion of an investor's portfolio. The Fund is not intended to be a complete investment program. Investors should consider the risks of the Fund before making an investment and be prepared to maintain the investment during periods of adverse market conditions. It is possible to lose money by investing in the Fund.

The following table identifies whether the strategies and risks discussed in this section (listed in alphabetical order) are principal or non-principal to the Fund. The Statement of Additional Information ("SAI") contains additional information about investment strategies and their related risks.

The Fund is actively managed and does not seek to replicate the performance of a specified index. On each business day, before commencement of trading on the NYSE Arca, the Fund will disclose on [________________] the identities and quantities of the Fund’s portfolio holdings that will form the basis for the Fund’s calculation of the Fund’s net asset value at the end of the business day.

Bank Loans (also known as Senior Floating Rate Interests)

Bank loans typically hold the most senior position in the capital structure of a business entity (the "Borrower"), are typically secured by specific collateral, and have a claim on the assets and/or stock of the Borrower that is senior to that held by unsecured subordinated debtholders and stockholders of the Borrower. The proceeds of bank loans are primarily used to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, dividends, and, to a lesser extent, to finance internal growth and for other corporate purposes. Bank loans are typically structured and administered by a financial institution that acts as the agent of the lenders participating in the bank loan. Most bank loans that will be purchased by the fund are rated below-investment-grade (sometimes called “junk”) or will be comparable if unrated, which means they are more likely to default than investment-grade loans. A default could lead to non-payment of income which would result in a reduction of income to the fund. There can be no assurance that the liquidation of any collateral would satisfy the Borrower's obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated. Most bank loans are not traded on any national securities exchange. Bank loans generally have less liquidity than investment-grade bonds and there may be less public information available about them.

The secondary market for loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may cause the fund to be unable to realize full value and thus cause a material decline in the fund's net asset value.

Bank loans pay interest at rates that are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or the London InterBank Offered Rate (LIBOR) or the prime rate offered by one or more major U.S. banks.

Bank loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for the borrower to repay, prepayments of senior floating rate interests may occur.

Convertible Securities

Convertible securities are usually fixed-income securities that a fund has the right to exchange for equity securities at a specified conversion price. Convertible securities include corporate bonds, notes or preferred stocks of U.S. or foreign issuers. Convertible securities allow the Fund to realize additional returns if the market price of the equity securities exceeds the conversion price. For example, the Fund may hold fixed-income securities that are convertible into shares of common stock at a conversion price of $10 per share. If the market value of the shares of common stock reached $12, the Fund could realize an additional $2 per share by converting its fixed-income securities.

Convertible securities have lower yields than comparable fixed-income securities. In addition, at the time a convertible security is issued the conversion price exceeds the market value of the underlying equity securities. Thus, convertible securities may provide lower returns than non-convertible fixed-income securities or equity securities depending upon changes in the price of the underlying equity securities. However, convertible securities permit the Fund to realize some of the potential appreciation of the underlying equity securities with less risk of losing its initial investment.

Depending on the features of the convertible security, the Fund will treat a convertible security as either a fixed-income or equity security for purposes of investment policies and limitations because of the unique characteristics of convertible securities. The Fund may invest in convertible securities that are below investment grade. Many convertible securities are relatively illiquid.

Derivatives

The Fund may invest in certain derivative strategies to earn income, manage or adjust the risk profile of the Fund, replace more direct investments, or obtain exposure to certain markets. Generally, a derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Certain derivative securities are described more accurately as index/structured securities. Index/structured securities are derivative securities whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices, or other financial indicators (reference indices).

There are many different types of derivatives and many different ways to use them. Futures, forward contracts, and options are commonly used for traditional hedging purposes to attempt to protect a Fund from loss due to changing interest rates, securities prices, asset values, or currency exchange rates and as a low-cost method of gaining exposure to a particular market without investing directly in those securities or assets. The Fund may enter into put or call options, futures contracts, options on futures contracts, over-the-counter swap contracts (e.g., interest rate swaps, total return swaps and credit default swaps), currency futures contracts and options, options on currencies, and forward currency contracts for both hedging and non-hedging purposes. The Fund also may use foreign currency options and foreign currency forward contracts to increase exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another. A forward currency contract involves a privately negotiated obligation to purchase or sell a specific currency at a future date at a price set in the contract. The Fund will not hedge currency exposure to an extent greater than the approximate aggregate market value of the securities held or to be purchased by the Fund (denominated or generally quoted or currently convertible into the currency). The Fund may enter into forward commitment agreements, which call for the Fund to purchase or sell a security on a future date at a fixed price. The Fund may also enter into contracts to sell its investments either on demand or at a specific interval.

Generally, a Fund may not invest in a derivative security unless the reference index or the instrument to which it relates is an eligible investment for the Fund or the reference currency relates to an eligible investment for the Fund.

The return on a derivative security may increase or decrease, depending upon changes in the reference index or instrument to which it relates. If the Fund's Sub-Advisors hedge market conditions incorrectly or employs a strategy that does not correlate well with the Fund's investment, these techniques could result in a loss. These techniques may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed.

The risks associated with derivative investments include:

Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement.

Credit default swap agreements involve special risks because they may be difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). Credit default swaps can increase credit risk because the Fund has exposure to both the issuer of the referenced obligation and the counterparty to the credit default swap.

Forward and futures contracts are subject to special risk considerations. The primary risks associated with the use of these contracts are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the sub-advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates, asset values, and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

For currency contracts, there is also a risk of government action through exchange controls that would restrict the ability of the Fund to deliver or receive currency.

Some of the risks associated with options include imperfect correlation, 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.

Emerging Markets

Principal defines emerging market securities as those issued by:

Usually, the term "emerging market country" means any country which is considered to be an emerging country by the international financial community (including the MSCI Emerging Markets Index or has a sovereign debt rating of BBB+ or lower based on the lower of S&P and Moody’s ratings). These countries generally include every nation in the world except the U.S., Canada, Japan, Australia, New Zealand, and most nations located in Western Europe.

Investments in companies of emerging (also called "developing") countries are subject to higher risks than investments in companies in more developed countries. These risks include:

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital, and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. The Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

Equity Securities

Equity securities include common stocks, preferred stock, depositary receipts, rights (a right is an offering of common stock to investors who currently own shares which entitle them to buy subsequent issues at a discount from the offering price), and warrants (a warrant grants its owner the right to purchase securities from the issuer at a specified price, normally higher than the current market price). Common stocks, the most familiar type, represent an equity (ownership) interest in a corporation. The value of a company's stock may fall as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company's products or services. A stock's value may also fall because of factors affecting not just the company, but also companies in the same industry or in a number of different industries, such as increases in production costs. The value of a company's stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates. In addition, a company's stock generally pays dividends only after the company invests in its own business and makes required payments to holders of its bonds and other debt. For this reason, the value of a company's stock will usually react more strongly than its bonds and other debt to actual or perceived changes in the company's financial condition or prospects. Some Funds focus their investments on certain market capitalization ranges. Market capitalization is defined as total current market value of a company's outstanding equity securities. The market capitalization of companies in the Fund’s portfolios and their related indexes will change over time and, the Fund will not automatically sell a security just because it falls outside of the market capitalization range of its index(es). Stocks of smaller companies may be more vulnerable to adverse developments than those of larger companies.

Exchange Traded Funds ("ETFs")

Generally, ETFs (and other exchange-traded equity securities, such as ETPs) invest in a portfolio of securities, but they may also invest in other assets, such as securities indices, government bonds, or currencies. Often ETFs are a type of index or actively managed fund bought and sold on a securities exchange. An ETF trades like common stock. Shares in an index ETF represent an interest in a fixed portfolio of securities designed to track a particular market index. The Fund could purchase shares issued by an ETF to gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities or for other reasons. The risks of owning an ETF generally reflect the risks of owning the underlying securities or other assets they are designed to track, although ETFs have management fees that increase their costs. Fund shareholders indirectly bear their proportionate share of the expenses of the ETFs in which the Fund invests.

Fixed-Income Securities

Fixed-income securities include bonds and other debt instruments that are used by issuers to borrow money from investors (some examples include corporate bonds, convertible bonds, mortgage-backed securities, U.S. government securities and asset-backed securities). The issuer generally pays the investor a fixed, variable, or floating rate of interest. The amount borrowed must be repaid at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are sold at a discount from their face values.

Fixed income securities include agency securities (debt instruments issued by U.S. government-sponsored entities and other federally related entities such as the Federal National Mortgage Association (FNMA), Federal Home Loan Bank and the Federal Home Loan Bank (FHLB)); asset-backed securities (debt instruments secured by a loan, lease or receivables against assets); residential mortgage-backed securities (debt instruments secured by a residential mortgage or a collection of mortgages); commercial mortgage-backed securities (debt instruments secured by a loan on a commercial property); inverse floaters (bonds or other types of debt instruments whose coupon rate has an inverse relationship to a benchmark rate); covered securities (secured debt instruments generally issued by credit institutions and backed by a pool of assets usually mortgages or public sector loans; sinking fund securities (bonds or other types of debt instruments that are subject to periodic payments by the issuer to a trustee. The trustee uses the payments to retire part of the bond issuance by purchasing the bonds in the open market); equipment trust certificates (debt instruments secured by equipment or other physical assets, with the title of the equipment or other physical assets held in trust for the holders of the debt instruments); sovereign bonds (debt instruments issued by national governments); convertible bonds (debt instruments that can be converted into common stock of the issuing company); pay-in-kind securities (debt instruments that pay investors in the form of additional securities rather than cash); and step coupon securities (debt instruments that pay interest at predetermined rates which increase or decrease over time).

Foreign Securities

Principal defines foreign securities as those issued by:

• companies with their principal place of business or principal office outside the U.S. or

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets, there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of Fund assets is not invested and earning no return. If the Fund is unable to make intended security purchases due to settlement problems, the Fund may miss attractive investment opportunities. In addition, the Fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, or diplomatic developments that could affect the Fund's investments in those countries. In addition, the Fund may also suffer losses due to nationalization, expropriation, or differing accounting practices and treatments. Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, currency convertibility or exchange rates could result in investment losses for the Fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to Fund investors. To protect against future uncertainties in foreign currency exchange rates, the Fund is authorized to enter into certain foreign currency exchange transactions.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Fund intends to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which the Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may reduce the liquidity of the Fund's portfolio. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

The Fund may choose to invest in a foreign company by purchasing depositary receipts. Depositary receipts are certificates of ownership of shares in a foreign-based issuer held by a bank or other financial institution. They are alternatives to purchasing the underlying security but are subject to the foreign securities risks to which they relate.

Hedging

The success of the Fund’s hedging strategy will be subject to the Sub-Advisors’ ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or

time passes, the success of the Fund’s hedging strategy will also be subject to the Sub-Advisors’ ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Sub-Advisors may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own costs.

High Yield Securities

Below investment grade bonds, which are rated at the time of purchase Ba1 or lower by Moody's and BB+ or lower by S&P (if the bond has been rated by only one of those agencies, that rating will determine if the bond is below investment grade; if the bond has not been rated by either of those agencies, the Sub-Advisors will determine whether the bond is of a quality comparable to those rated below investment grade), are sometimes referred to as high yield or "junk bonds" and are considered speculative. Such securities could be in default at time of purchase.

Investment in high yield bonds involves special risks in addition to the risks associated with investment in highly rated debt securities. High yield bonds may be regarded as predominantly speculative with respect to the issuer's continuing ability to meet principal and interest payments. Moreover, such securities may, under certain circumstances, be less liquid than higher rated debt securities.

Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality debt securities. The ability of the Fund to achieve its investment objective may, to the extent of its investment in high yield bonds, be more dependent on such credit analysis than would be the case if the Fund were investing in higher quality bonds.

High yield bonds may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher-grade bonds. The prices of high yield bonds have been found to be less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual corporate developments. If the issuer of high yield bonds defaults, the Fund may incur additional expenses to seek recovery. To the extent that such high yield issuers undergo a corporate restructuring, such high yield securities may become exchanged for or converted into reorganized equity of the underlying issuer. High yield bonds oftentimes include complex legal covenants that impose various degrees of restriction on the issuer’s ability to take certain actions, such as distribute cash to equity holders, incur additional indebtedness, and dispose of assets. To the extent that a bond indenture or loan agreement does not contain sufficiently protective covenants or otherwise permits the issuer to take certain actions to the detriment of the holder of the fixed-income security, the underlying value of such fixed-income security may decline.

The secondary market on which high yield bonds are traded may be less liquid than the market for higher-grade bonds. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield bond and could adversely affect and cause large fluctuations in the daily price of the Fund's shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of high yield bonds, especially in a thinly traded market.

The use of credit ratings for evaluating high yield bonds also involves certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield bonds. Also, credit rating agencies may fail to change credit ratings in a timely manner to reflect subsequent events. If a credit rating agency changes the rating of a portfolio security held by the Fund, the Fund may retain the security if Principal or Sub-Advisors think it is in the best interest of shareholders.

Inverse Floating Rate Investments

Inverse floating rate investments are variable rate debt instruments that pay interest at rates that move in the opposite direction of prevailing interest rates. Inverse floating rate investments tend to underperform the market for fixed rate bonds in a rising interest rate environment. Inverse floating rate investments have varying degrees of liquidity. Inverse floating rate investments in which the Fund may invest may include derivative instruments, such as residual interest bonds or tender option bonds. Such instruments are typically created by a special purpose trust that holds long-term fixed rate bonds and sells two classes of beneficial interests: short-term floating rate interests, which are sold to third party investors, and the inverse floating residual interests, which are purchased by the Fund. The Fund generally invests in inverse floating rate investments that include embedded leverage, thus exposing the Fund to greater risks and increased costs. The market value of a "leveraged" inverse floating rate investment generally will fluctuate in response to changes in market rates of interest to a greater extent than the value of an unleveraged investment. The Fund making such an investment will segregate on its books liquid securities having a value equal to the market value of the bonds underlying the “leveraged” inverse floating rate investment.

Investment Companies

Because the Fund may invest in other investment companies, its investment performance may depend on the investment performance of the underlying investment companies in which it invests. An investment in an investment company is subject to the risks associated with that investment company. Fund shareholders indirectly bear their proportionate share of the expenses of the investment companies in which the Fund invests.

Leverage

If the Fund makes investments in futures contracts, forward contracts, swaps and other derivative instruments, these instruments provide the economic effect of financial leverage by creating additional investment exposure, as well as the potential for greater loss. If the Fund uses leverage through activities such as borrowing, entering into short sales, purchasing securities on margin or on a “when-issued” basis or purchasing derivative instruments in an effort to increase its returns, the Fund has the risk of magnified capital losses that occur when losses affect an asset base, enlarged by borrowings or the creation of liabilities, that exceeds the net assets of the Fund. The net asset value of the Fund employing leverage will be more volatile and sensitive to market movements. Leverage may involve the creation of a liability that requires the Fund to pay interest. Leveraging may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet segregation requirements when it may not be advantageous to do so. To the extent that the Fund is not able to close out a leveraged position because of market illiquidity, the Fund’s liquidity may be impaired to the extent that it has a substantial portion of liquid assets segregated or earmarked to cover obligations.

Liquidity Risk

The Fund is exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund's ability to sell particular securities or close derivative positions at an advantageous price. Funds with principal investment strategies that involve securities of companies with smaller market capitalizations, foreign securities, derivatives, high yield bonds and bank loans or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk.

Management Risk

If a Sub-Advisor's investment strategies do not perform as expected, the Fund could underperform other Funds with similar investment objectives or lose money. As an actively managed Fund, the Fund’s performance will reflect in part the ability of Principal and/or Sub-Advisor(s) to make investment decisions that are suited to achieving the Fund's investment objective. Funds that are actively managed are prepared to invest in securities, sectors, or industries differently from the benchmark.

Market Volatility and Issuer Risk

The value of the Fund's portfolio securities may go down in response to overall stock or bond market movements. Markets tend to move in cycles, with periods of rising prices and periods of falling prices. Stocks tend to go up and down in value more than bonds. If the Fund's investments are concentrated in certain sectors, its performance could be worse than the overall market. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of a security may decline for reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services. It is possible to lose money when investing in the Fund.

Master Limited Partnerships

Master limited partnerships ("MLPs") tend to pay relatively higher distributions than other types of companies. The amount of cash that each individual MLP can distribute to its partners will depend on the amount of cash it generates from operations, which will vary from quarter to quarter depending on factors affecting the market generally and on factors affecting the particular business lines of the MLP. Available cash will also depend on the MLPs' level of operating costs (including incentive distributions to the general partner), level of capital expenditures, debt service requirements, acquisition costs (if any), fluctuations in working capital needs and other factors. The benefit derived from investment in MLPs depends largely on the MLPs being treated as partnerships for federal income tax purposes. As a partnership, an MLP has no federal income tax liability at the entity level. If, because of a change in current law or a change in an MLP's business, an MLP were to be treated as a corporation for federal income tax purposes, the MLP would be obligated to pay federal income tax on its income at the corporate tax rate. If an MLP were to be classified as a corporation for federal income tax purposes, the amount of cash available for distribution would be reduced and the distributions received might be taxed entirely as dividend income.

Municipal Obligations and AMT-Subject Bonds

The term “municipal obligations” generally is understood to include debt obligations issued by municipalities to obtain funds for various public purposes. The two principal classifications of municipal bonds are "general obligation" and "revenue" bonds. General obligation bonds are secured by the issuer's pledge of its full faith and credit, with either limited or unlimited taxing power for the payment of principal and interest. Revenue bonds are not supported by the

issuer's full taxing authority. Generally, they are payable only from the revenues of a particular facility, a class of facilities, or the proceeds of another specific revenue source.

"AMT-subject bonds" are municipal obligations issued to finance certain "private activities," such as bonds used to finance airports, housing projects, student loan programs, and water and sewer projects. Interest on AMT-subject bonds is an item of tax preference for purposes of the federal individual alternative minimum tax ("AMT") and will also give rise to corporate alternative minimum taxes. See "Tax Considerations" for a discussion of the tax consequences of investing in the Fund.

Current federal income tax laws limit the types and volume of bonds qualifying for the federal income tax exemption of interest, which may have an effect upon the ability of the Fund to purchase sufficient amounts of tax-exempt securities.

Portfolio Turnover

"Portfolio Turnover" is the term used in the industry for measuring the amount of trading that occurs in a Fund's portfolio during the year. For example, a 100% turnover rate means that on average every security in the portfolio has been replaced once during the year. Funds that engage in active trading may have high portfolio turnover rates. Funds with high turnover rates (more than 100%) often have higher transaction costs (which are paid by the Fund) and may lower the Fund's performance. Please consider all the factors when you compare the turnover rates of different Funds.

Preferred Securities

Preferred securities generally pay fixed rate dividends and/or interest (though some are adjustable rate) and typically have "preference" over common stock in payment priority and the liquidation of a company's assets - preference means that a company must pay on its preferred securities before paying on its common stock, and the claims of preferred securities holders are typically ahead of common stockholders' claims on assets in a corporate liquidation. Holders of preferred securities usually have no right to vote for corporate directors or on other matters. The market value of preferred securities is sensitive to changes in interest rates as they are typically fixed income securities - the fixed-income payments are expected to be the primary source of long-term investment return. While some preferred securities are issued with a final maturity date, others are perpetual in nature. In certain instances, a final maturity date may be extended and/or the final payment of principal may be deferred at the issuer’s option for a specified time without triggering an event of default for the issuer. In addition, an issuer of preferred securities may have the right to redeem the securities prior to their stated maturity date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws. As with call provisions, a redemption by the issuer may reduce the return of the security held by the Fund. Preferred securities may be subject to provisions that allow an issuer, under certain circumstances to skip (indefinitely) or defer (possibly up to 10 years) distributions. If the Fund owns a preferred security that is deferring its distribution, the Fund may be required to report income for tax purposes while it is not receiving any income.

Preferred securities are typically issued by corporations, generally in the form of interest or dividend bearing instruments, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The preferred securities market is generally divided into the $25 par “retail” and the $1,000 par “institutional” segments. The $25 par segment includes securities that are listed on the New York Stock Exchange (exchange traded), which trade and are quoted with accrued dividend or interest income, and which are often callable at par value five years after their original issuance date. The institutional segment includes $1,000 par value securities that are not exchange-listed (over the counter), which trade and are quoted on a “clean” price, i.e., without accrued dividend or interest income, and which often have a minimum of 10 years of call protection from the date of their original issuance.

Real Estate Investment Trusts

Real estate investment trust securities ("REITs") involve certain unique risks in addition to those risks associated with investing in the real estate industry in general (such as possible declines in the value of real estate, lack of availability of mortgage funds, or extended vacancies of property). REITs are characterized as: equity REITs, which primarily own property and generate revenue from rental income; mortgage REITs, which invest in real estate mortgages; and hybrid REITs, which combine the characteristics of both equity and mortgage REITs. Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified, and are subject to heavy cash flow dependency, risks of default by borrowers, and self-liquidation. As an investor in a REIT, the Fund will be subject to the REIT’s expenses, including management fees, and will remain subject to the Fund's advisory fees with respect to the assets so invested. REITs are also subject to the possibilities of failing to qualify for the special tax treatment accorded REITs under the Internal Revenue Code, and failing to maintain their exemptions from registration under the 1940 Act.

Investment in REITs involves risks similar to those associated with investing in small market capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, and may be subject to more abrupt or erratic price movements than larger company securities.

Real Estate Securities

Investing in securities of companies in the real estate industry, subjects the Fund to the special risks associated with the real estate market and the real estate industry in general. Generally, companies in the real estate industry are considered to be those that have principal activity involving the development, ownership, construction, management or sale of real estate; have significant real estate holdings, such as hospitality companies, healthcare facilities, supermarkets, mining, lumber and/or paper companies; and/or provide products or services related to the real estate industry, such as financial institutions that make and/or service mortgage loans and manufacturers or distributors of building supplies. Securities of companies in the real estate industry are sensitive to factors such as loss to casualty or condemnation, changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use and rents, and the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws.

Repurchase Agreements

Repurchase agreements typically involve the purchase of debt securities from a financial institution such as a bank, savings and loan association, or broker-dealer. A repurchase agreement provides that the Fund sells back to the seller and that the seller repurchases the underlying securities at a specified price on a specific date. Repurchase agreements may be viewed as loans by the Fund collateralized by the underlying securities. This arrangement results in a fixed rate of return that is not subject to market fluctuation while the Fund holds the security. In the event of a default or bankruptcy by a selling financial institution, the affected Fund bears a risk of loss. To minimize such risks, the Fund enters into repurchase agreements only with parties a Sub-Advisor deems creditworthy (those that are large, well-capitalized and well-established financial institutions). In addition, the value of the securities collateralizing the repurchase agreement is, and during the entire term of the repurchase agreement remains, at least equal to the repurchase price, including accrued interest.

Securitized Products

Securitized products are fixed income instruments that represent interest in underlying pools of collateral or assets. The value of the securitized product is derived from the performance, value, and cash flows of the underlying asset(s). The fund’s investments in securitized products are subject to risks similar to traditional fixed income securities, such as credit, interest rate, liquidity, prepayment, extension, and default risk, as well as additional risks associated with the nature of the assets and the servicing of those assets. Prepayment risk may make it difficult to calculate the average life of a fund’s investment in securitized products. Securitized products are generally issued as pass-through certificates, which represent the right to receive principal and interest payments collected on the underlying pool of assets, which are passed through to the security holder. Therefore, repayment depends on the cash flows generated by the underlying pool of assets. The securities may be rated as investment-grade or below-investment-grade.

Shares May Trade at Prices Different Than NAV

The net asset value (NAV) of the Shares generally will fluctuate with changes in the market value of the Fund's holdings. The market prices of the Shares generally will fluctuate in accordance with changes in NAV, as well as the relative supply of and demand for Shares on NYSE Arca. Principal cannot predict whether the Shares will trade below, at or above their NAV. Price differences may be due largely to the fact that supply and demand forces at work in the secondary trading market for the Shares will be related, but not identical, to the same forces influencing the prices of the securities held by the Fund (individually or in the aggregate) at any time. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from NAV. If a shareholder purchases at a time when the market price is at a premium to the NAV or sells at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Given that Shares can be created and redeemed only in Creation Units at NAV, Principal believes that large discounts and premiums should not be sustained over the long term. Since foreign exchanges may be open on days when the Fund does not price its shares, the value of the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares.

Small and Medium Market Capitalization Companies

The Fund may invest in securities of companies with small- or mid-sized market capitalizations. Market capitalization is defined as total current market value of a company's outstanding common stock. Investments in companies with smaller market capitalizations may involve greater risks and price volatility (wide, rapid fluctuations) than investments in larger, more mature companies. Small companies may be less significant within their industries and may be at a competitive disadvantage relative to their larger competitors. While smaller companies may be subject to these additional risks, they may also realize more substantial growth than larger or more established companies.

Smaller companies may be less mature than larger companies. At this earlier stage of development, the companies may have limited product lines, reduced market liquidity for their shares, limited financial resources, or less depth in management than larger or more established companies. Unseasoned issuers are companies with a record of less than three years continuous operation, including the operation of predecessors and parents. Unseasoned issuers by their nature have only a limited operating history that can be used for evaluating the company's growth prospects. As a result, these securities may place a greater emphasis on current or planned product lines and the reputation and experience of the company's management and less emphasis on fundamental valuation factors than would be the case for more mature growth companies.

Temporary Defensive Measures

From time to time, as part of its investment strategy, the Fund may invest without limit in cash and cash equivalents for temporary defensive purposes in response to adverse market, economic, or political conditions. To the extent that the Fund is in a defensive position, it may lose the benefit of upswings and limit its ability to meet its investment objective. For this purpose, cash equivalents include: bank notes, bank certificates of deposit, bankers' acceptances, repurchase agreements, commercial paper, and commercial paper master notes, which are floating rate debt instruments without a fixed maturity. In addition, the Fund may purchase U.S. government securities, preferred stocks, and debt securities, whether or not convertible into or carrying rights for common stock.

There is no limit on the extent to which the Fund may take temporary defensive measures. In taking such measures, the Fund may fail to achieve its investment objective.

Trading Issues

Although the shares of the Fund are expected to be listed on the NYSE Arca, there can be no assurance that an active trading market for such shares will develop or be maintained.

Trading in Shares on NYSE Arca may be halted due to market conditions or for reasons that, in the view of NYSE Arca, make trading in Shares inadvisable. In addition, trading in Shares on NYSE Arca is subject to trading halts caused by extraordinary market volatility pursuant to NYSE Arca "circuit breaker" rules. There can be no assurance that the requirements of NYSE Arca necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

PORTFOLIO HOLDINGS INFORMATION

A description of the Fund's policies and procedures with respect to disclosure of the Fund's portfolio securities is available in the Fund's SAI.

MANAGEMENT OF THE FUND

The Manager

Principal Management Corporation (“Principal”) serves as the manager for the Fund. Through the Management Agreement with the Fund, Principal provides investment advisory services and certain corporate administrative services for the Fund.

Principal is an indirect subsidiary of Principal Financial Group, Inc. and has managed mutual funds since 1969. Principal’s address is 655 9th Street, Des Moines, Iowa 50392.

The Sub-Advisor(s)

Principal has signed contracts with sub-advisors. Under each sub-advisory agreement, the Sub-Advisor agrees to assume the obligations of Principal to provide investment advisory services to the portion of the assets of the Fund allocated to it by Principal. For these services, Principal pays the Sub-Advisor a fee.

Principal or the Sub-Advisors provide the Trustees of the Fund with a recommended investment program. The program must be consistent with the Fund's investment objective and policies. Within the scope of the approved investment program, the Sub-Advisors advise the Fund on its investment policy and determines which securities are bought or sold, and in what amounts.

The Fund summary identifies the portfolio managers of the Fund. Additional information about the portfolio managers follows. The SAI provides additional information about each portfolio manager’s compensation, other accounts the portfolio managers manage, and each portfolio manager’s ownership of securities in the Fund.

There are multiple portfolio managers, and they allocatio portfolio management responsibilities as follows: [ ].

Charles D. Averill previously was a Senior Quantitative Analyst and has worked at Edge since 1990. He earned a bachelor’s degree in Economics from Reed College and an M.A. in Economics from Princeton University. Mr. Averill has earned the right to use the Chartered Financial Analyst designation.

Jill R. Cuniff became President of Edge in 2009 and became Portfolio Manager in 2010. Before becoming the President of Edge, Ms. Cuniff was the President of Morley Financial. She earned a bachelor’s degree in Business Finance from Montana State University.

Todd A. Jablonski has been with Edge since 2010. Previously, he was Executive Director and Portfolio Manager at UBS. Before that, he was the lead Portfolio Manager of US large cap strategies at Credit Suisse Asset Management. He earned a bachelor’s degree in Economics from the University of Virginia and an M.B.A. with an emphasis in Quantitative Finance from New York University's Stern School of Business. Mr. Jablonski has earned the right to use the Chartered Financial Analyst designation.

Barbara A. McKenzie has been with Principal since 1984. She currently serves as senior executive director -- Chief Operating Officer at PGI. She earned her bachelor's degree from the University of Iowa, and her master's degree from Indiana University.

Edge Asset Management, Inc. (“Edge”) will be responsible for constructing a model portfolio for the Fund each day. The model will express Edge’s view of how the portfolio ought to be constructed that day under ideal circumstances. Edge’s model will not consider issues such as availability of a particular security or the effect a particular security might have on an authorized participant or market maker’s view of the creation basket that the Fund is required to publish before the start of trading each day. Edge’s model each day may consist of no changes to the portfolio since the previous day. In that case, Edge’s model would simply repeat the portfolio from the previous day. But the model may also reflect deletion of securities that Edge believes the Fund should liquidate, in whole or in part, and the acquisition of new securities.

Edge will deliver the model to Principal Global Investors, LLC (“PGI”) each day, leaving sufficient time prior to the open of trading to allow PGI to review the model portfolio and determine whether it wishes to make changes to it. PGI will make changes to the model portfolio if it determines that securities Edge has included will have a detrimental effect on the Creation Unit the Fund will publish before the open of trading the next day. (See “PURCHASE AND REDEMPTION OF CREATION UNITS” in the SAI)

Fees Paid to Principal

The Fund pays Principal a fee for its services, which includes the fee Principal pays to the Sub-Advisors and to [to be added by amendment] for fund administration, fund accounting and other services . The management fee schedules for the Fund, which has not completed a full fiscal year, are as follows:

[Table to be added in later amendment]

A discussion regarding the basis for the Board of Trustees approval of the management agreement with Principal and the sub-advisory agreements with PGI and Edge will be available in the [annual][semi-annual] report to shareholders for the period ending [DATE].

Manager of Managers

The Fund operates as a Manager of Managers. Under an order received from the SEC (the "current order"), the Fund and Principal may enter into and materially amend agreements with unaffiliated and wholly-owned affiliated sub-advisors (affiliated sub-advisors which are at least 95% owned, directly or indirectly, by Principal or an affiliated person of Principal) without obtaining shareholder approval. Principal may, without obtaining shareholder approval:

Additionally, the Fund has applied to the SEC for an amended e xemptive order, which if granted, would allow Principal to also enter into and materially amend agreements with majority-owned affiliated sub-advisors (affiliated sub-advisors which are at least 50% owned, directly or indirectly, by Principal or an affiliated person of Principal) (the "majority-owned order"). There is no assurance, however, that the SEC will grant the majority-owned order.

Principal has ultimate responsibility for the investment performance of each Fund that utilizes a Sub-Advisor due to its responsibility to oversee Sub-Advisors and recommend their hiring, termination, and replacement. No fund will rely on the current order, the majority-owned order, or any future order until it receives approval from its shareholders (or in the case of a new Fund, the Fund's sole initial shareholder before the Fund is available to other purchasers).

The shareholders of the Fund have approved the Fund’s reliance on the current order. The shareholders of the Fund have also approved reliance on the majority-owned relief, should the SEC grant that relief in the future.

DISTRIBUTOR AND OTHER FUND SERVICE PROVIDERS

[Distributor name to be added in future amendment] (the "Distributor") serves as the distributor of Creation Units for the Fund. The Distributor does not maintain a secondary market in Shares.

[Administrator/Custodian and Transfer Agent name(s) to be added in future amendment] is the administrator, custodian, transfer agent, Fund accounting, and dividend disbursing agent for the Fund.

PRICING OF FUND SHARES

The Fund will directly issue and redeem Shares on a continuous basis at net asset value (NAV) per Share in aggregations of 50,000 Shares called “Creation Units.” The value of the Fund’s Shares bought and sold in the secondary market (on NYSE Arca) will be determined by market price, as described in the section below.

The Board of Trustees has delegated day-to-day valuation oversight responsibilities to Principal. Principal has established a Valuation Committee to fulfill these oversight responsibilities. The New York Stock Exchange (“NYSE”) will disseminate every 15 seconds throughout the trading day through the facilities of the Consolidated Tape Association an amount representing, on a per Share basis, the sum of the current value of the Portfolio Positions that were publicly disclosed prior to the commencement of trading in Shares on the NYSE. This approximate value should not be viewed as a "real-time" update of the NAV per Share of the Fund because the approximate value may not be calculated in the same manner as the NAV, which is computed once a day, at the end of the business day. The Fund is not involved in, or responsible for, the calculation or dissemination of the approximate value and the Fund does not make any warranty as to its accuracy.

[ ]will calculate the NAV of each share of Fund each day the NYSE is open (share prices are not calculated on the days on which the NYSE is closed for trading, generally New Year’s Day, Martin Luther King, Jr. Day, Washington’s Birthday/ Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas). The share price is determined as of the close of business of the NYSE (normally 3:00 p.m. Central Time).

Notes:

Fund Share Trading Prices – Secondary Market

The trading prices of Shares of the Fund on NYSE Arca may differ from the Fund's daily NAV. The price of the Shares will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio securities. Secondary market Shares, which are available for purchase or sale on an intraday basis, do not have a fixed relationship to either the previous day’s NAV or to the current day’s NAV. Prices in the secondary market, therefore, may be below, at, or above the most recently calculated NAV per Share.

The approximate value of shares of the Fund, known as the “indicative optimized portfolio value” (“IOPV”) will be disseminated every [fifteen seconds] throughout the trading day by the national securities exchange on which the Fund is listed or by other information providers or market data vendors. The IOPV is based on the current market value of the securities and cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time nor the best possible valuation of the current portfolio. The IOPV should not be viewed as a “real-time” update of the NAV, because the IOPV may not be calculated in the same manner as the NAV, which is computed once a day as discussed below. The IOPV is generally determined by using current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no warranty as to its accuracy.

Shares of the Fund may trade in the secondary market on days when the Fund does not accept orders to purchase or redeem shares. On such days, shares may trade in the secondary market with more significant premiums or discounts than might otherwise be experienced on days when the Fund accepts purchase and redemption orders.

Information regarding how often the Shares of the Fund traded on NYSE Arca at a price above (at a premium) or below (at a discount) the NAV per Share of the Fund during the past four calendar quarters (if available) can be found at [_________________]. Data presented represents past performance and cannot be used to predict future results.

PURCHASE AND SALE OF FUND SHARES

Generally

Shareholders who are not Authorized Participants or “APs" (as defined below) will not be able to purchase or redeem Shares directly with or from the Fund. As a result, most investors will buy and sell Shares of the Fund in secondary market transactions through brokers. Shares of the Fund are expected to be listed for trading on the secondary market on NYSE Arca. Shares can be bought and sold throughout the trading day like other publicly traded shares. There is no minimum investment. When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction. Due to the costs of buying or selling shares, including bid/ask spreads, frequent trading of shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. The Shares of the Fund are expected to trade under the symbol [ ]. Contact your broker for additional information on how to buy and sell Shares.

The Fund will directly issue shares to Authorized Participants on a continuous basis at net asset value (NAV) per Share in aggregations of 50,000 Shares called “Creation Units,” in exchange for portfolio securities. APs may acquire Shares directly from the Fund, and APs may tender their Shares for redemption directly to the Fund, at NAV per Share only in Creation Units or Creation Unit Aggregations, and in accordance with the procedures described in the SAI. An Authorized Participant or “AP” is either: (a) a broker or dealer registered under the Exchange Act or other participant in the Continuous Net Settlement System of the National Securities Clearing Corporation (“NSCC”), a clearing agency registered with the Commission and affiliated with the Depository Trust Company (“DTC”); or (b) a participant in the DTC (such participant, “DTC Participant”). Shares are not individually redeemable, but are redeemable only in Creation Unit aggregations, and in exchange for portfolio securities and/or cash. A Creation Unit of the Fund will consist of a block of 50,000 shares, which is subject to change.

All orders to purchase or redeem Creation Units must be placed with the Distributor by or through an Authorized Participant that has entered into a participant agreement with the Distributor with respect to the creation and redemption of Creation Units. An investor purchasing or redeeming a Creation Unit from the Fund may be charged a fee (“Transaction Fee”) to protect existing shareholders of the Fund from the dilutive costs associated with the purchase and redemption of Creation Units.

Principal may recommend to the Board, and the Board may elect, to liquidate and terminate the Fund at any time without shareholder approval.

Book Entry

Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company ("DTC") or its nominee is the record owner of all outstanding Shares of the Fund and is recognized as the owner of all Shares for all purposes.

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other stocks that you hold in book entry or "street name" form.

DIVIDENDS AND DISTRIBUTIONS

The Fund intends to generally make distributions of net income monthly. The factors that could affect the Fund’s ability to make regular monthly distributions include, without limitation, changes in interest rates, the performance of the financial markets in which the Fund invests, the allocation of Fund assets across different asset classes and investments, the performance of the Fund’s investment strategies, and the amount and timing of the Fund’s prior distributions. The Fund intends to make monthly income payments to shareholders on or about the 15th calendar day

of each month. The Fund seeks to tailor the amount of its monthly income payments to moderate fluctuations in the amounts it distributes to shareholders over the course of the year. Although the Fund attempts to moderate fluctuations, the amounts it distributes to shareholders are not fixed and may not be the same each month. Further, the Fund does not guarantee it will make any monthly income payments to its shareholders. The Fund may make an additional distribution at the end of the year in order to comply with applicable law. This additional distribution may include an income component that may be higher or lower than the Fund’s regular monthly income payment. The Fund does not expect to make distributions that will be treated as return of capital, although it cannot guarantee that it will not do so. At the end of the year, the Fund may be required under applicable law to re-characterize distributions for the year among ordinary income, capital gains, and return of capital (if any) for purposes of tax reporting to shareholders.

To the extent that distributions the Fund pays are derived from a source other than net income (such as a return of capital), a notice will be included in your quarterly statement pursuant to Section 19(a) of the Investment Company Act of 1940, as amended, and Rule 19a-1 disclosing the source of such distributions. Furthermore, such notices shall be posted monthly on our web site at [_________________]. You may request a copy of all such notices, free of charge, by telephoning [ ]. The amounts and sources of distributions included in such notices are estimates only and you should not rely upon them for purposes of reporting income taxes. The Fund will send shareholders a Form 1099-DIV for the calendar year that will provide shareholders with information for reporting these distributions for federal income tax purposes.

No dividend reinvestment service is provided by the Trust. Broker-dealers may make available DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

FREQUENT PURCHASES AND REDEMPTIONS

To minimize the potential consequences of frequent purchases and redemptions of Shares, the Fund employs fair valuation pricing and imposes transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs the Fund incurs in effecting trades. In addition, Principal monitors trades by APs for patterns of abusive trading, and the Fund reserves the right, without prior written notice, to not accept orders from APs that Principal has determined may be disruptive to the management of the Fund or otherwise are not in the best interests of the Fund. For these reasons, the Board has determined that it is not necessary to impose excessive trading restrictions to implement the Fund’s policy of not knowingly accommodating excessive trading in Fund shares.

TAX CONSIDERATIONS

The following discussion summarizes some of the possible consequences under current federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You also may be subject to state, local, and/or foreign tax on Fund distributions and sales of Shares. Consult your personal tax advisor about the potential tax consequences of an investment in Shares under all applicable tax laws. For more information, please see the section entitled "Taxes" in the SAI.

Taxes

As with any investment, you should consider how your investment in Shares will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in Shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA plan, you need to be aware of the possible tax consequences when:

Taxes on Distributions

As stated above, dividends from net investment income and net capital gains, ordinarily, are declared and paid monthly. The Fund also may pay a special distribution at the end of the calendar year to comply with federal tax requirements. In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in the Fund.

Dividends paid out of the Fund's income and net realized short-term capital gains, if any, are generally taxable as ordinary income, except that the Fund’s dividends attributable to its “qualified dividend income” (i.e., dividends received on stock of most domestic and foreign corporations, including Chinese corporations, with respect to which the Fund satisfies certain holding period and other restrictions) generally will be subject to federal income tax for individual and certain other non-corporate shareholders (each, an “individual shareholder”) who satisfy those restrictions with respect to their Fund shares at the lower rates for long-term capital gains—a maximum of 15% (or 20% for individual shareholders with taxable income exceeding certain thresholds, which will be adjusted annually for inflation after 2013). Distributions of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains, regardless of how long you have held the Shares.

Distributions in excess of the Fund's current and accumulated earnings and profits, if any, are treated as a tax-free return of capital to the extent of your basis in the Shares, and as capital gain thereafter. A distribution will reduce the Fund's NAV per Share and may be taxable to you as ordinary income or long-term capital gains even though, from an investment standpoint, the distribution may constitute a return of capital.

By law, the Fund may be required to withhold a percentage of your distributions and proceeds if you have not provided your taxpayer identification number or social security number.

Taxes on Share Sales

Any capital gain or loss you realize upon a sale of Shares generally is treated as long-term capital gain, taxable at the rates mentioned above for individual shareholders, or loss if you held the Shares for more than one year and as short-term capital gain or loss if you held the Shares for one year or less . The ability to deduct capital losses may be limited.

Taxes on Purchase and Redemption of Creation Units

An AP who exchanges equity securities for Creation Units generally will recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the exchanger's aggregate basis in the securities surrendered and the cash component paid. A person who exchanges Creation Units for equity securities generally will recognize a gain or loss equal to the difference between the exchanger's basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing "wash sales," or on the basis that there has been no significant change in economic position. Persons exchanging securities should consult their own tax advisors with respect to whether wash sale rules apply and when a loss might be deductible.

Any capital gain or loss realized upon redemption of Creation Units generally is treated as long-term capital gain or loss if the Shares have been held for more than one year and as a short-term capital gain or loss if the Shares have been held for one year or less.

DISTRIBUTION PLANS AND INTERMEDIARY COMPENSATION

Distribution and/or Service (12b-1) Fees

The Trust has adopted a distribution plan pursuant to Rule 12b-1 under the Investment Company Act for the Fund. Under the 12b-1 Plan, the Fund is authorized to pay fees for distribution related expenses and/or for providing services to shareholders of up to [ ]% of the Fund’s average daily net assets each year.

No 12b-1 fees are currently paid by the Fund, and there are no current plans to impose these fees. In addition, no such fee may be paid in the future without further approval by the Board of Trustees, and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

However, in the event 12b-1 fees are charged in the future, because Rule 12b-1 fees are paid out of Fund assets and are ongoing fees, over time they will increase the cost of your investment in the Funds and may cost you more than other types of sales charges.

Additional Payments to Intermediaries

Shares of the Fund are sold primarily through intermediaries, such as brokers, dealers, investment advisors, banks, trust companies, pension plan consultants, retirement plan administrators and insurance companies.

In some cases, Principal, the Distributor, or their respective affiliates will provide payments or reimbursements in connection with the costs of conferences, educational seminars, training and marketing efforts related to the Fund. Such activities may be sponsored by intermediaries, Principal, or the Distributor. The costs associated with such activities may include travel, lodging, entertainment, and meals. In some cases, Principal or the Distributor will also provide payment or reimbursement for expenses associated with transactions ("ticket") charges and general marketing expenses. For more information, see the SAI.

The payments described in this prospectus may create a conflict of interest by influencing your Financial Professional or your intermediary to recommend the Fund over another investment. Ask your Financial Professional or visit your intermediary's website for more information about the total amounts paid to them by Principal and its affiliates, and by sponsors of other mutual funds your Financial Professional may recommend to you.

Your intermediary may charge you additional fees other than those disclosed in this prospectus. Ask your Financial Professional about any fees and commissions they charge.

FUND ACCOUNT INFORMATION

Continuous Offering

The method by which Creation Unit Aggregations of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Unit Aggregations of Shares are issued and sold by the Fund on an ongoing basis, a "distribution," as such term is used in the Securities Act of 1933, as amended (the "Securities Act"), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Unit Aggregations after placing an order with the Distributor, breaks them down into constituent Shares and sells such Shares directly to customers, or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms also should note that dealers who are not "underwriters" but are effecting transactions in Shares, whether or not participating in the distribution of Shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3)(C) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not "underwriters" but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions), and thus dealing with the Shares that are part of an overallotment within the meaning of Section 4(a)(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act only is available with respect to transactions on a national exchange.

Reservation of Rights

The Trust reserves the right to amend or terminate the Fund, as well as certain terms related to the Fund, described in this prospectus. Shareholders will be notified of any such action to the extent required by law.

Householding

Householding is an option available to certain investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Householding is available through certain broker-dealers. If you are interested in enrolling in householding and receiving a single copy of certain shareholder documents, please contact your broker-dealer. If you are currently enrolled in householding and wish to change your householding status, please contact your broker-dealer.

Multiple Translations

This prospectus may be translated into other languages. In the event of any inconsistencies or ambiguity as to the meaning of any word or phrase in a translation, the English text will prevail.

Financial Statements

Shareholders will receive annual financial statements for the Funds, audited by the Funds’ independent registered public accounting firm. Shareholders will also receive a semiannual financial statement that is unaudited.

Section 12(d)(1)

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. However, registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1) subject to certain terms and conditions set forth in an SEC exemptive order issued to the Trust, including that such investment companies enter into an agreement with the Trust on behalf of the Fund prior to exceeding the limits imposed by Section 12(d)(1).

NOTE: Moody’s appends numerical modifiers, 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking, and the modifier 3 indicates a ranking in the lower end of that generic rating category.

SHORT-TERM NOTES: The four ratings of Moody’s for short-term notes are MIG 1, MIG 2, MIG 3, and MIG 4. MIG 1 denotes “best quality, enjoying strong protection from established cash flows.” MIG 2 denotes “high quality” with “ample margins of protection.” MIG 3 notes are of “favorable quality...but lacking the undeniable strength of the preceding grades.” MIG 4 notes are of “adequate quality, carrying specific risk for having protection...and not distinctly or predominantly speculative.”

Description of Moody’s Commercial Paper Ratings:

Moody’s Commercial Paper ratings are opinions of the ability to repay punctually promissory obligations not having an original maturity in excess of nine months. Moody’s employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Issuers rated Prime-1 (or related supporting institutions) have a superior capacity for repayment of short-term promissory obligations.

Issuers rated Prime-2 (or related supporting institutions) have a strong capacity for repayment of short-term promissory obligations.

Issuers rated Prime-3 (or related supporting institutions) have an acceptable capacity for repayment of short-term promissory obligations.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Description of Standard & Poor’s Corporation’s Debt Ratings:

A Standard & Poor’s debt rating is a current assessment of the creditworthiness of an obligor with respect to a specific obligation. This assessment may take into consideration obligors such as guarantors, insurers, or lessees.

The debt rating is not a recommendation to purchase, sell or hold a security, inasmuch as it does not comment as to market price or suitability for a particular investor.

The ratings are based on current information furnished by the issuer or obtained by Standard & Poor’s from other sources Standard & Poor’s considers reliable. Standard & Poor’s does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or for other circumstances.

The ratings are based, in varying degrees, on the following considerations:

Plus (+) or Minus (-): The ratings from “AA” to “B” may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

Provisional Ratings: The letter “p” indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the bonds being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

Standard & Poor’s, Commercial Paper Ratings

A Standard & Poor’s Commercial Paper Rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days. Ratings are graded into four categories, ranging from “A” for the highest quality obligations to “D” for the lowest. Ratings are applicable to both taxable and tax-exempt commercial paper. The four categories are as follows:

The Commercial Paper Rating is not a recommendation to purchase or sell a security. The ratings are based on current information furnished to Standard & Poor’s by the issuer and obtained by Standard & Poor’s from other sources it considers reliable. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability of, such information.

Standard & Poor’s rates notes with a maturity of less than three years as follows:

Fitch, Inc. Long-Term Credit Ratings

Investment Grade

Defaulted obligations typically are not assigned ‘D’ ratings, but are instead rated in the ‘B’ to ‘C’ rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

Recovery Ratings

Recovery Ratings are assigned to selected individual securities and obligations. These currently are published for most individual obligations of corporate issuers with IDRs in the ‘B’ rating category and below, and for selected structured finance obligations in low speculative grade.

Among the factors that affect recovery rates for securities are the collateral, the seniority relative to other obligations in the capital structure (where appropriate), and the expected value of the company or underlying collateral in distress.

The Recovery Rating scale is based upon the expected relative recovery characteristics of an obligation upon the curing of a default, emergence from insolvency or following the liquidation or termination of the obligor or its associated collateral. For structured finance, Recovery Ratings are designed to estimate recoveries on a forward-looking basis while taking into account the time value of money.

Recovery Ratings are an ordinal scale and do not attempt to precisely predict a given level of recovery. As a guideline in developing the rating assessments, the agency employs broad theoretical recovery bands in its ratings approach based on historical averages, but actual recoveries for a given security may deviate materially from historical averages.

Short-Term Credit Ratings

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity or security stream, and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, structured and sovereign obligations, and up to 36 months for obligations in US public finance markets.

The information in this Statement of Additional Information is not complete and may be changed.  We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective.  This Statement of Additional Information is not an offer to sell these securities and is not soliciting an offer to buy these securities in any state in which the offer or sale is not permitted.

GENERAL DESCRIPTION OF TRUST AND FUND

The Principal Exchange-Traded Funds ("the Trust") is a statutory trust organized under the laws of the State of Delaware in 2013 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company, registered under the Investment Company Act of 1940, as amended (the "1940 Act"). The Trust currently consists of one series, the Principal EDGE Active Income ETF (the “Fund”). The Fund is "diversified," and as such, the Fund's investments are required to meet certain diversification requirements under the 1940 Act. The shares of the Fund are referred to herein as "Shares."

The Trust issues and redeems Shares at net asset value ("NAV") only with Authorized Participants (“APs”) and only in aggregations of 50,000 Shares (each a "Creation Unit" or a "Creation Unit Aggregation"), which is subject to change. The Fund issues and redeems Creation Units in exchange for portfolio securities and/or cash, plus a fixed and/or variable transaction fee.

The Fund is expected to be approved for listing, subject to notice of issuance, on NYSE Arca, Inc. ("NYSE Arca" or the "Exchange"). Shares trade on the Exchange at market prices that may be below, at, or above NAV.

EXCHANGE LISTING AND TRADING

Shares of the Fund are expected to be listed for trading and trade throughout the day on NYSE Arca.

Once listed, there can be no assurance that the Fund will continue to meet the requirements of the Exchange necessary to maintain the listing of its Shares. The Exchange may, but is not required to, remove the Shares of the Fund from listing if: (i) following the initial 12-month period beginning at the commencement of trading of the Fund, there are fewer than 50 beneficial owners of the Shares of the Fund for 30 or more consecutive trading days; or (ii) such other event shall occur or condition shall exist that, in the opinion of the Exchange, makes further dealings on such Exchange inadvisable. The Exchange will remove the Shares of the Fund from listing and trading upon termination of the Fund.

As in the case of other stocks traded on the Exchange, brokers' commissions on transactions will be based on negotiated commission rates at customary levels.

The Trust reserves the right to adjust the price levels of the Shares in the future to help maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

DESCRIPTION OF THE FUND’S INVESTMENTS AND RISKS

Fund Policies

The investment objectives, investment strategies and the principal risks of the Fund are described in the Prospectus. This Statement of Additional Information contains supplemental information about those strategies and risks and the types of securities the Sub-Advisors can select for the Fund. Additional information is also provided about other the strategies that the Fund may use to try to achieve its objective.

The composition of the Fund and the techniques and strategies that the Sub-Advisors may use in selecting securities will vary over time. The Fund is not required to use all of the investment techniques and strategies available to it in seeking its goals.

Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the restrictions apply at the time transactions are entered into. Accordingly, any later increase or decrease beyond the specified limitation, resulting from market fluctuations or in a rating by a rating service, does not require elimination of any security from the Fund’s portfolio.

The investment objective of the Fund and, except as described below as "Fundamental Restrictions," the investment strategies described in this Statement of Additional Information and the Prospectus are not fundamental and may be changed by the Trust’s Board of Trustees without shareholder approval. The Fundamental Restrictions may not be changed without a vote of a majority of the outstanding voting securities of the Fund. The Investment Company Act of 1940, as amended, ("1940 Act") provides that "a vote of a majority of the outstanding voting securities" of the Fund means the affirmative vote of the lesser of 1) more than 50% of the outstanding shares or 2) 67% or more of the shares present at a meeting if more than 50% of the outstanding Fund shares are represented at the meeting in person or by proxy. Each share has one vote.

With the exception of the diversification test required by the Internal Revenue Code, the Fund will not consider collateral held in connection with securities lending activities when applying any of the following fundamental restrictions or any other investment restriction set forth in the Fund's Prospectus or Statement of Additional Information.

Fundamental Restrictions – Principal EDGE Active Income ETF

The following numbered restrictions for the Fund is a matter of fundamental policy and may not be changed without shareholder approval.

Non-Fundamental Restrictions – Principal EDGE Active Income ETF

The Fund has also adopted the following restrictions that are not fundamental policies and may be changed without shareholder approval. It is contrary to the Fund's present policy to:

Investment Strategies and Risks

The Fund may not invest in all of the instruments and techniques described below. In addition, the Fund is free to reduce or eliminate its activity with respect to any of the investment techniques described below without changing the Fund’s fundamental investment policies. The Fund will periodically change the composition of its portfolio to best meet its investment objective. The Fund is also indirectly subject to the risks associated with the portfolio securities and investment techniques of other investment companies’ shares that the Fund may purchase. For more information about the Fund’s principal strategies and risks, please see the Fund’s Prospectus.

Senior Securities

Under the 1940 Act, a fund that borrows money is required to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300% of the amount borrowed, with an exception for borrowings not in excess of 5% of the fund’s total assets made for temporary or emergency purposes. Pursuant to SEC staff interpretations of the Act, a fund that purchases securities or makes other investments that have a leveraging effect on the fund (for example, reverse repurchase agreements) must segregate assets to render them not available for sale or other disposition in an amount equal to the amount the fund owes pursuant to the terms of the security or other investment.

Commodities

Under the 1940 Act, a fund's registration statement must recite the fund's policy with regard to investing in commodities. Pursuant to a claim for exclusion filed with the Commodity Futures Trading Commission (“CFTC”) on behalf of the Fund, neither the Trust nor the Fund is deemed to be a “commodity pool” or “commodity pool operator” under the Commodity Exchange Act (“CEA”), and they are therefore not subject to registration or regulation under the CEA. The CFTC recently amended rule 4.5 “Exclusion for certain otherwise regulated persons from the definition of the term “commodity pool operator.” Rule 4.5 provides that an investment company does not meet the definition of “commodity pool operator” if its use of futures contracts, options on futures contracts and swaps is sufficiently limited that the fund can fall within one of two exclusions set out in rule 4.5. The Fund intends to limit its use of futures contracts, options on futures contracts and swaps to the degree necessary to fall within one of the two exclusions. If the Fund is unable to do so, it may incur expenses that are necessary to comply with the CEA and rules the CFTC has adopted under it.

Borrowing

If the Fund invests the proceeds of borrowing, borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of the Fund’s portfolio. If the Fund invests the proceeds of borrowing, money borrowed will be subject to interest costs that may or may not be recovered by earnings on the securities purchased. The Fund also may be required to maintain minimum average balances in connection with a borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

The 1940 Act limits a fund’s ability to borrow money. For example, a fund may borrow for temporary purposes so long as the amount borrowed does not exceed 5% of the fund's total assets.

Industry Concentration

“Concentration” means a fund invests more than 25% of its net assets in a particular industry or group of industries. To monitor compliance with the policy regarding industry concentration, the Fund may use the industry classifications provided by Bloomberg, L.P., the Morgan Stanley Capital International/Standard & Poor's Global Industry Classification Standard (GICS), the Directory of Companies Filing Annual Reports with the Securities and Exchange Commission or any other reasonable industry classification system. The Fund interprets its policy with respect to concentration in a particular industry to apply only to direct investments in the securities of issuers in a particular industry. For purposes of this restriction, government securities such as treasury securities or mortgage-backed securities that are issued or guaranteed by the U.S. government, its agencies or instrumentalities are not subject to the Fund’s industry concentration restrictions. The Fund views its investments in privately issued mortgage-related securities, asset-backed securities or tax-exempt municipal securities as not representing interests in any particular industry or group of industries. For information about municipal securities, see the Municipal Obligations section.

Restricted and Illiquid Securities

A fund may experience difficulty in valuing and selling illiquid securities and, in some cases, may be unable to value or sell certain illiquid securities for an indefinite period of time. Illiquid securities may include a wide variety of investments, such as (1) repurchase agreements maturing in more than seven days (unless the agreements have demand/redemption features), (2) OTC options contracts and certain other derivatives (including certain swap agreements), (3) fixed time deposits that are not subject to prepayment or do not provide for withdrawal penalties upon prepayment (other than overnight deposits), (4) loan interests and other direct debt instruments, (5) certain municipal lease obligations, (6) commercial paper issued pursuant to Section 4(2) of the 1933 Act, (7) thinly-traded securities, and (8) securities whose resale is restricted under the federal securities laws or contractual provisions (including restricted, privately placed securities that, under the federal securities laws, generally may be resold only to qualified institutional buyers). Generally, restricted securities may be sold only in a public offering for which a registration statement has been filed and declared effective or in a transaction that is exempt from the registration requirements of the Securities Act of 1933. When registration is required, a fund that owns restricted securities may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of

the decision to sell and the time the Fund may be permitted to sell a restricted security. If adverse market conditions were to develop during such a period, the fund might obtain a less favorable price than existed when it decided to sell.

Illiquid and restricted securities are priced at fair value as determined in good faith by or under the direction of the Directors. The Fund has adopted investment restrictions that limit its investments in restricted securities or other illiquid securities to no more than 15% of its net assets. The Trustees have adopted procedures to determine the liquidity of Rule 4(2) short-term paper and of restricted securities that may be resold under Rule 144A. Securities determined to be liquid under these procedures are excluded from the preceding investment restriction.

Foreign Securities

Foreign companies may not be subject to the same uniform accounting, auditing, and financial reporting practices as are required of U.S. companies. In addition, there may be less publicly available information about a foreign company than about a U.S. company. Securities of many foreign companies are less liquid and more volatile than securities of comparable U.S. companies. Commissions on foreign securities exchanges may be generally higher than those on U.S. exchanges.

Foreign markets also have different clearance and settlement procedures than those in U.S. markets. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct these transactions. Delays in settlement could result in temporary periods when a portion of a fund's assets is not invested and is earning no return. If a fund is unable to make intended security purchases due to settlement problems, the fund may miss attractive investment opportunities. In addition, a fund may incur a loss as a result of a decline in the value of its portfolio if it is unable to sell a security.

With respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political, or social instability, or diplomatic developments that could affect a fund's investments in those countries. In addition, a fund may also suffer losses due to nationalization, expropriation, or differing accounting practices and treatments.

Investments in foreign securities are subject to laws of the foreign country that may limit the amount and types of foreign investments. Changes of governments or of economic or monetary policies, in the U.S. or abroad, changes in dealings between nations, currency convertibility, or exchange rates could result in investment losses for a fund. Finally, even though certain currencies may be convertible into U.S. dollars, the conversion rates may be artificial relative to the actual market values and may be unfavorable to a fund's investors.

Foreign securities are often traded with less frequency and volume, and therefore may have greater price volatility, than is the case with many U.S. securities. Brokerage commissions, custodial services, and other costs relating to investment in foreign countries are generally more expensive than in the U.S. Though the Fund intends to acquire the securities of foreign issuers where there are public trading markets, economic or political turmoil in a country in which the Fund has a significant portion of its assets or deterioration of the relationship between the U.S. and a foreign country may negatively impact the liquidity of the Fund's portfolio. The Fund may have difficulty meeting a large number of redemption requests. Furthermore, there may be difficulties in obtaining or enforcing judgments against foreign issuers.

Investments in companies of developing (also called “emerging”) countries are subject to higher risks than investments in companies in more developed countries. These risks include:

In addition, many developing countries have experienced substantial and, in some periods, extremely high rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had and may continue to have negative effects on the economies and securities markets of those countries.

Repatriation of investment income, capital and proceeds of sales by foreign investors may require governmental registration and/or approval in some developing countries. The Fund could be adversely affected by delays in or a refusal to grant any required governmental registration or approval for repatriation.

Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

Depositary Receipts

Depositary Receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as, currency risk, political and economic risk, and market risk, because their values depend on the performance of a foreign security denominated in its home currency.

The Fund may invest in foreign securities which means it may invest in:

Depositary Receipts may be issued by sponsored or unsponsored programs. In sponsored programs, an issuer has made arrangements to have its securities traded in the form of Depositary Receipts. In unsponsored programs, the issuer may not be directly involved in the creation of the program. Although regulatory requirements with respect to sponsored and unsponsored programs are generally similar, in some cases it may be easier to obtain financial information from an issuer that has participated in the creation of a sponsored program. Accordingly, there may be less information available regarding issuers of securities of underlying unsponsored programs, and there may not be a correlation between the availability of such information and the market value of the Depositary Receipts.

Securities of Smaller Companies

The Fund may invest in securities of companies with small- or mid-sized market capitalizations. Market capitalization is defined as total current market value of a company's outstanding common stock. Investments in companies with smaller market capitalizations may involve greater risks and price volatility (wide, rapid fluctuations) than investments in larger, more mature companies. Smaller companies may be less mature than older companies. At this earlier stage of development, the companies may have limited product lines, reduced market liquidity for their shares, limited financial resources or less depth in management than larger or more established companies. Small companies also may be less significant within their industries and may be at a competitive disadvantage relative to their larger competitors. While smaller companies may be subject to these additional risks, they may also realize more substantial growth than larger or more established companies. Small company stocks may decline in price as large company stocks rise, or rise in price while larger company stocks decline. Investors should therefore expect the net asset value of a fund that invests a substantial portion of its assets in small company stocks may be more volatile than the shares of a fund that invests solely in larger company stocks.

Unseasoned Issuers

The Fund may invest in the securities of unseasoned issuers. Unseasoned issuers are companies with a record of less than three years continuous operation, including the operation of predecessors and parents. Unseasoned issuers by their nature have only a limited operating history that can be used for evaluating the companies' growth prospects. As a result, investment decisions for these securities may place a greater emphasis on current or planned product lines and the reputation and experience of the company's management and less emphasis on fundamental valuation factors than would be the case for more mature growth companies. In addition, many unseasoned issuers also may be small companies and involve the risks and price volatility associated with smaller companies.

Convertible Securities

A convertible security is a bond, debenture, note, preferred stock, or other security that entitles the holder to acquire common stock or other equity securities of the same or a different issuer. A convertible security generally entitles the holder to receive interest paid or accrued until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to non-convertible debt or preferred securities, as applicable. Convertible securities rank senior to common stock in a corporation’s capital structure and, therefore, generally entail less risk than the corporation’s common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a fixed income security. Convertible securities are subordinate in rank to any senior debt obligations of the issuer, and, therefore, an issuer’s convertible securities entail more risk than its debt obligations. Convertible securities generally

offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of the potential for capital appreciation. In addition, convertible securities are often lower-rated securities.

Because of the conversion feature, the price of the convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset, and as such is subject to risks relating to the activities of the issuer and/or general market and economic conditions. The income component of a convertible security may tend to cushion the security against declines in the price of the underlying asset. However, the income component of convertible securities causes fluctuations based upon changes in interest rates and the credit quality of the issuer.

If the "conversion value" of a convertible security increases to a point that approximates or exceeds its "investment value," the value of the security will be principally influenced by its conversion value. If the conversion value of a convertible security increases to a point that approximates or exceeds its investment value, the value of the security will be principally influenced by its conversion value. A convertible security will sell at a premium over its conversion value to the extent investors place value on the right to acquire the underlying common stock while holding an income-producing security.

A convertible security may be subject to redemption at the option of the issuer at a predetermined price. If a convertible security held by a fund is called for redemption, the fund would be required to permit the issuer to redeem the security and convert it to underlying common stock, or would sell the convertible security to a third party, which may have an adverse effect on the fund’s ability to achieve its investment objective.

Options on Securities and Securities Indices, and Futures Contracts and Options on Futures Contracts

The Fund may each engage in the practices described under this heading.

The Fund may purchase or write both exchange-traded and over-the-counter (“OTC”) options. OTC options differ from exchange-traded options in that they are two-party contracts, with price and other terms negotiated between buyer and seller, and generally do not have as much market liquidity as exchange-traded options. An OTC option (an option not traded on an established exchange) may be closed out only by agreement with the other party to the original option transaction. With OTC options, a fund is at risk that the other party to the transaction will default on its obligations or will not permit the Fund to terminate the transaction before its scheduled maturity. While a fund will seek to enter into OTC options only with dealers who agree to or are expected to be capable of entering into closing transactions with a fund, there can be no assurance that a fund will be able to liquidate an OTC option at a favorable price at any time prior to its expiration. OTC options are not subject to the protections afforded purchasers of listed options by the Options Clearing Corporation or other clearing organizations. An exchange-traded option may be closed out only on an exchange that generally provides a liquid secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, it might not be possible to effect a closing transaction with respect to a particular option, with the result that a fund would have to exercise the option in order to consummate the transaction.

The premium received by a fund reflects, among other factors, the current market price of the underlying security, the relationship of the exercise price to the market price, the time period until the expiration of the option and interest rates. The premium generates additional income for the fund if the option expires unexercised or is closed out at a profit. By writing a call, a fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option, but it retains the risk of loss if the price of the security should decline. By writing a put, a fund assumes the risk that it may have to purchase the underlying security at a price that may be higher than its market value at time of exercise.

The Fund writes only covered options and comply with applicable regulatory and exchange cover requirements. The Fund usually owns the underlying security covered by any outstanding call option. With respect to an outstanding put option, the Fund deposits and maintains with its custodian or segregates on the Fund's records, cash, or other liquid assets with a value at least equal to the market value of the option that was written.

Once a fund has written an option, it may terminate its obligation before the option is exercised. The fund executes a closing transaction by purchasing an option of the same series as the option previously written. The fund has a gain or loss depending on whether the premium received when the option was written exceeds the closing purchase price plus related transaction costs.

When a fund purchases a put option, it receives, in return for the premium it pays, the right to sell to the writer of the option the underlying security at a specified price at any time before the option expires. A fund purchases put options in anticipation of a decline in the market value of the underlying security. During the life of the put option, the fund is able to sell the underlying security at the exercise price regardless of any decline in the market price of the underlying security. In order for a put option to result in a gain, the market price of the underlying security must decline, during the option period, below the exercise price enough to cover the premium and transaction costs.

Once a fund purchases an option, it may close out its position by selling an option of the same series as the option previously purchased. The fund has a gain or loss depending on whether the closing sale price exceeds the initial purchase price plus related transaction costs.

specified price. In most instances, these contracts are closed out by entering into an offsetting transaction before the settlement date. The fund realizes a gain or loss depending on whether the price of an offsetting purchase plus transaction costs are less or more than the price of the initial sale or on whether the price of an offsetting sale is more or less than the price of the initial purchase plus transaction costs. Although the fund usually liquidates futures contracts on financial instruments, by entering into an offsetting transaction before the settlement date, they may make or take delivery of the underlying securities when it appears economically advantageous to do so.

A futures contract based on a securities index provides for the purchase or sale of a group of securities at a specified future time for a specified price. These contracts do not require actual delivery of securities but result in a cash settlement. The amount of the settlement is based on the difference in value of the index between the time the contract was entered into and the time it is liquidated (at its expiration or earlier if it is closed out by entering into an offsetting transaction).

When a fund purchases or sells a futures contract, it pays a commission to the futures commission merchant through which the fund executes the transaction. When entering into a futures transaction, the fund does not pay the execution price, as it does when it purchases a security, or a premium, as it does when it purchases an option. Instead, the fund deposits an amount of cash or other liquid assets (generally about 5% of the futures contract amount) with its futures commission merchant. This amount is known as "initial margin." In contrast to the use of margin account to purchase securities, the fund's deposit of initial margin does not constitute the borrowing of money to finance the transaction in the futures contract. The initial margin represents a good faith deposit that helps assure the fund's performance of the transaction. The futures commission merchant returns the initial margin to the fund upon termination of the futures contract if the fund has satisfied all its contractual obligations.

Subsequent payments to and from the futures commission merchant, known as "variation margin," are required to be made on a daily basis as the price of the futures contract fluctuates, a process known as "marking to market." The fluctuations make the long or short positions in the futures contract more or less valuable. If the position is closed out by taking an opposite position prior to the settlement date of the futures contract, a final determination of variation margin is made. Any additional cash is required to be paid to or released by the broker and the fund realizes a loss or gain.

In using futures contracts, a fund may seek to establish with more certainty than would otherwise be possible the effective price of or rate of return on portfolio securities or securities that the fund proposes to acquire. A fund, for example, sells futures contracts in anticipation of a rise in interest rates that would cause a decline in the value of its debt investments. When this kind of hedging is successful, the futures contract increases in value when the fund's debt securities decline in value and thereby keeps the fund's net asset value from declining as much as it otherwise would. A fund may also sell futures contracts on securities indices in anticipation of or during a stock market decline in an endeavor to offset a decrease in the market value of its equity investments. When a fund is not fully invested and anticipates an increase in the cost of securities it intends to purchase, it may purchase financial futures contracts. When increases in the prices of equities are expected, a fund may purchase futures contracts on securities indices in order to gain rapid market exposure that may partially or entirely offset increases in the cost of the equity securities it intends to purchase.

Upon the exercise of a call, the writer of the option is obligated to sell the futures contract (to deliver a long position to the option holder) at the option exercise price, which will presumably be lower than the current market price of the contract in the futures market. Upon exercise of a put, the writer of the option is obligated to purchase the futures contract (deliver a short position to the option holder) at the option exercise price, which will presumably be higher than the current market price of the contract in the futures market. However, as with the trading of futures, most options are closed out prior to their expiration by the purchase or sale of an offsetting option at a market price that reflects an increase or a decrease from the premium originally paid. Options on futures can be used to hedge substantially the same risks addressed by the direct purchase or sale of the underlying futures contracts. For example, if a fund anticipates a rise in interest rates and a decline in the market value of the debt securities in its portfolio, it might purchase put options or write call options on futures contracts instead of selling futures contracts.

If the Fund purchases an option on a futures contract, it may obtain benefits similar to those that would result if it held the futures position itself. But in contrast to a futures transaction, the purchase of an option involves the

payment of a premium in addition to transaction costs. In the event of an adverse market movement, however, the Fund is not subject to a risk of loss on the option transaction beyond the price of the premium it paid plus its transaction costs.

When the Fund writes an option on a futures contract, the premium paid by the purchaser is deposited with the Fund's custodian. The Fund must maintain with its futures commission merchant all or a portion of the initial margin requirement on the underlying futures contract. It assumes a risk of adverse movement in the price of the underlying futures contract comparable to that involved in holding a futures position. Subsequent payments to and from the futures commission merchant, similar to variation margin payments, are made as the premium and the initial margin requirements are marked to market daily. The premium may partially offset an unfavorable change in the value of portfolio securities, if the option is not exercised, or it may reduce the amount of any loss incurred by the Fund if the option is exercised.

Prior to exercise or expiration, a position in futures may be terminated only by entering into a closing purchase or sale transaction. This requires a secondary market on the relevant contract market. The Fund enters into a futures contract or related option only if there appears to be a liquid secondary market. There can be no assurance, however, that such a liquid secondary market exists for any particular futures contract or related option at any specific time. Thus, it may not be possible to close out a futures position once it has been established. Under such circumstances, the Fund continues to be required to make daily cash payments of variation margin in the event of adverse price movements. In such situations, if the Fund has insufficient cash, it may be required to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to perform under the terms of the futures contracts it holds. The inability to close out futures positions also could have an adverse impact on the Fund's ability effectively to hedge its portfolio.

Most United States futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. This daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day's settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

on futures contracts for hedging or risk management purposes, the Fund determines that the price fluctuations in the contracts and options are substantially related to price fluctuations in securities held by the Fund or which it expects to purchase. In pursuing traditional hedging activities, the Fund may sell futures contracts or acquire puts to protect against a decline in the price of securities that the Fund owns. The Fund may purchase futures contracts or calls on futures contracts to protect the Fund against an increase in the price of securities the Fund intends to purchase before it is in a position to do so.

When the Fund purchases a futures contract, or writes a call option on a futures contract, it segregates liquid assets that, when added to the value of assets deposited with the futures commission merchant as margin, are equal to the market value of the contract.

High Yield Bonds (“Junk Bonds”)

Some funds invest a portion of their assets in bonds that are rated below investment grade (sometimes called “high yield bonds” or "junk bonds") which are rated at the time of purchase Ba1 or lower by Moody's and BB+ or lower by S&P (if the bond has been rated by only one of those agencies, that rating will determine whether the bond is below investment grade; if the bond has not been rated by either of those agencies, the Sub-Advisor will determine whether the bond is of a quality comparable to those rated below investment grade). Lower rated bonds involve a higher degree of credit risk, which is the risk that the issuer will not make interest or principal payments when due. In the event of an unanticipated default, the Fund would experience a reduction in its income and could expect a decline in the market value of the bonds so affected. Issuers of high yield securities may be involved in restructurings or bankruptcy proceedings that may not be successful.  If an issuer defaults, it may not be able to pay all or a portion of interest and principal owed to the fund, it may exchange the high yield securities owned by the fund for other securities, including equities, and/or the fund may incur additional expenses while seeking recovery of its investment. Some funds may also invest in unrated bonds of foreign and domestic issuers. Unrated bonds, while not necessarily of lower quality than rated bonds, may not have as broad a market. Because of the size and perceived demand of the issue, among other factors, certain municipalities may not incur the expense of obtaining a rating. The Sub-Advisor will analyze the creditworthiness of the issuer, as well as any financial institution or other party responsible for payments on the bond, in determining whether to purchase unrated bonds. Unrated bonds will be included in the limitation the Fund has with regard to high yield bonds unless the Sub-Advisor deems such securities to be the equivalent of investment grade bonds. Some of the high yield securities consist of Rule 144A securities. High yield securities may contain any type of interest rate payment or reset terms, including fixed rate, adjustable rate, zero coupon, contingent, deferred, payment-in-kind and those with auction rate features.

Mortgage- and Asset-Backed Securities

The yield characteristics of the mortgage- and asset-backed securities in which the Fund may invest differ from those of traditional debt securities. Among the major differences are that the interest and principal payments are made more frequently on mortgage- and asset-backed securities (usually monthly) and that principal may be prepaid at any time because the underlying mortgage loans or other assets generally may be prepaid at any time. As a result, if the Fund purchases those securities at a premium, a prepayment rate that is faster than expected will reduce their yield, while a prepayment rate that is slower than expected will have the opposite effect of increasing yield. If the Fund purchases these securities at a discount, faster than expected prepayments will increase their yield, while slower than expected prepayments will reduce their yield. Amounts available for reinvestment by the Fund are likely to be greater during a period of declining interest rates and, as a result, are likely to be reinvested at lower interest rates than during a period of rising interest rates.

In general, the prepayment rate for mortgage-backed securities decreases as interest rates rise and increases as interest rates fall. However, rising interest rates will tend to decrease the value of these securities. In addition, an increase in interest rates may affect the volatility of these securities by effectively changing a security that was considered a short-term security at the time of purchase into a long-term security. Long-term securities generally fluctuate more widely in response to changes in interest rates than short- or medium-term securities.

The market for privately issued mortgage- and asset-backed securities is smaller and less liquid than the market for U.S. government mortgage-backed securities. A collateralized mortgage obligation (“CMO”) may be structured in a manner that provides a wide variety of investment characteristics (yield, effective maturity, and interest rate sensitivity). As market conditions change, and especially during periods of rapid market interest rate changes, the ability of a CMO to provide the anticipated investment characteristics may be greatly diminished. Increased market volatility and/or reduced liquidity may result.

The Fund may invest in each of collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”), other collateralized debt obligations (“CDOs”) and other similarly structured securities. CBOs, CLOs and other CDOs are types of asset-backed securities. A CBO is a trust which is often backed by a diversified pool of high risk, below

investment grade fixed income securities. The collateral can be from many different types of fixed income securities such as high yield debt, residential privately issued mortgage-related securities, commercial privately issued mortgage-related securities, trust preferred securities and emerging market debt. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Other CDOs are trusts backed by other types of assets representing obligations of various parties. CBOs, CLOs and other CDOs may charge management fees and administrative expenses.

Inflation-Indexed Bonds

The Fund may invest in inflation-indexed bonds or inflation protected debt securities, which are fixed income securities whose value is periodically adjusted according to the rate of inflation. Two structures are common. The U.S. Treasury and some other issuers utilize a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the Consumer Price Index accruals as part of a semi-annual coupon. Inflation-indexed securities issued by the U.S. Treasury (Treasury Inflation Protected Securities or TIPS) have maturities of approximately five, ten or thirty years, although it is possible that securities with other maturities will be issued in the future. The U.S. Treasury securities pay interest on a semi-annual basis equal to a fixed percentage of the inflation-adjusted principal amount. If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if the rate of inflation rises at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond's inflation measure.

The periodic adjustment of U.S. inflation-indexed bonds is tied to the Consumer Price Index for Urban Consumers (CPI-U), which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index calculated by that government. Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.

Real Estate Investment Trusts (“REITs”)

REITs are pooled investment vehicles that invest in income producing real estate, real estate related loans, or other types of real estate interests. U.S. REITs are allowed to eliminate corporate level federal tax so long as they meet certain requirements of the Internal Revenue Code. Foreign REITs ("REIT-like") entities may have similar tax treatment in their respective countries. Equity real estate investment trusts own real estate properties, while mortgage real estate investment trusts make construction, development, and long-term mortgage loans. Their value may be affected by changes in the underlying property of the trusts, the creditworthiness of the issuer, property taxes, interest rates, and tax and regulatory requirements, such as those relating to the environment. Both types of trusts are not diversified, are dependent upon management skill, are subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, and the possibility of failing to qualify for tax-free status of income under the Internal Revenue Code and failing to maintain exemption from the 1940 Act. In addition, foreign REIT-like entities will be subject to foreign securities risks. (See "Foreign Securities")

Zero-Coupon Securities

The Fund may invest in zero-coupon securities. Zero-coupon securities have no stated interest rate and pay only the principal portion at a stated date in the future. They usually trade at a substantial discount from their face (par) value. Zero-coupon securities are subject to greater market value fluctuations in response to changing interest rates than debt obligations of comparable maturities that make distributions of interest in cash.

Master Limited Partnerships (“MLPs”)

An MLP is an entity that is generally taxed as a partnership for federal income tax purposes and that derives each year at least 90% of its gross income from "Qualifying Income". Qualifying Income includes interest, dividends, real estate rents, gain from the sale or disposition of real property, income and gain from commodities or commodity futures, and income and gain from mineral or natural resources activities that generate Qualifying Income. MLP interests (known as units) are traded on securities exchanges or over-the-counter. An MLP's organization as a partnership and compliance with the Qualifying Income rules generally eliminates federal tax at the entity level.

An MLP has one or more general partners (who may be individuals, corporations, or other partnerships) which manage the partnership, and limited partners, which provide capital to the partnership but have no role in its management. Typically, the general partner is owned by company management or another publicly traded sponsoring corporation. When an investor buys units in an MLP, the investor becomes a limited partner. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP in the event that a court determines that the rights of the holders of MLP units to vote to remove or replace the general partner of that MLP, to approve amendments to that MLP’s partnership agreement, or to take other action under the partnership agreement of that MLP would constitute “control” of the business of that MLP, or a court or governmental agency determines that the MLP is conducting business in a state without complying with the partnership statute of that state. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them.

The business of certain MLPs is affected by supply and demand for energy commodities because such MLPs derive revenue and income based upon the volume of the underlying commodity produced, transported, processed, distributed, and/ or marketed. Pipeline MLPs have indirect commodity exposure to oil and gas price volatility because, although they do not own the underlying energy commodity, the general level of commodity prices may affect the volume of the commodity the MLP delivers to its customers and the cost of providing services such as distributing natural gas liquids. The costs of natural gas pipeline MLPs to perform services may exceed the negotiated rates under “negotiated rate” contracts. Processing MLPs may be directly affected by energy commodity prices. Propane MLPs own the underlying energy commodity, and therefore have direct exposure to energy commodity prices. The MLP industry in general could be hurt by market perception that MLP's performance and valuation are directly tied to commodity prices.

Pipeline MLPs are common carrier transporters of natural gas, natural gas liquids (primarily propane, ethane, butane and natural gasoline), crude oil or refined petroleum products (gasoline, diesel fuel and jet fuel). Pipeline MLPs also may operate ancillary businesses such as storage and marketing of such products. Pipeline MLPs derive revenue from capacity and transportation fees. Historically, pipeline output has been less exposed to cyclical economic forces due to its low cost structure and government-regulated nature. In addition, most pipeline MLPs have limited direct commodity price exposure because they do not own the product being shipped.

Processing MLPs are gatherers and processors of natural gas as well as providers of transportation, fractionation and storage of natural gas liquids ("NGLs"). Processing MLPs derive revenue from providing services to natural gas producers, which require treatment or processing before their natural gas commodity can be marketed to utilities and other end user markets. Revenue for the processor is fee based, although it is not uncommon to have some participation in the prices of the natural gas and NGL commodities for a portion of revenue.

Propane MLPs are distributors of propane to homeowners for space and water heating. Propane MLPs derive revenue from the resale of the commodity on a margin over wholesale cost. The ability to maintain margin is a key to profitability. Propane serves approximately 3% of the household energy needs in the United States, largely for homes beyond the geographic reach of natural gas distribution pipelines. Approximately 70% of annual cash flow is earned during the winter heating season (October through March). Accordingly, volumes are weather dependent, but have utility type functions similar to electricity and natural gas.

MLPs operating interstate pipelines and storage facilities are subject to substantial regulation by the Federal Energy Regulatory Commission ("FERC"), which regulates interstate transportation rates, services and other matters regarding natural gas pipelines including: the establishment of rates for service; regulation of pipeline storage and liquified natural gas facility construction; issuing certificates of need for companies intending to provide energy services or constructing and operating interstate pipeline and storage facilities; and certain other matters. FERC also regulates the interstate transportation of crude oil, including: regulation of rates and practices of oil pipeline companies; establishing equal service conditions to provide shippers with equal access to pipeline transportation; and establishment of reasonable rates for transporting petroleum and petroleum products by pipeline.

MLPs are subject to various federal, state and local environmental laws and health and safety laws as well as laws and regulations specific to their particular activities. These laws and regulations address: health and safety standards for the operation of facilities, transportation systems and the handling of materials; air and water pollution requirements and standards; solid waste disposal requirements; land reclamation requirements; and requirements relating to the handling and disposition of hazardous materials. MLPs are subject to the costs of compliance with such laws applicable to them, and changes in such laws and regulations may adversely affect their results of operations.

MLPs may be subject to liability relating to the release of substances into the environment, including liability under federal “Superfund” and similar state laws for investigation and remediation of releases and threatened releases of hazardous materials, as well as liability for injury and property damage for accidental events, such as explosions or

discharges of materials causing personal injury and damage to property. Such potential liabilities could have a material adverse effect upon the financial condition and results of operations of MLPs.

MLPs are subject to numerous business related risks, including: deterioration of business fundamentals reducing profitability due to development of alternative energy sources, consumer sentiment with respect to global warming, changing demographics in the markets served, unexpectedly prolonged and precipitous changes in commodity prices and increased competition that reduces the MLP’s market share; the lack of growth of markets requiring growth through acquisitions; disruptions in transportation systems; the dependence of certain MLPs upon the energy exploration and development activities of unrelated third parties; availability of capital for expansion and construction of needed facilities; a significant decrease in natural gas production due to depressed commodity prices or otherwise; the inability of MLPs to successfully integrate recent or future acquisitions; and the general level of the economy.

Securities Lending

The Fund may lend its portfolio securities. The Fund will not lend its portfolio securities if as a result the aggregate of such loans made by the Fund would exceed the limits established by the 1940 Act (in general, the Fund may not lend more than 33 1/3% of total fund assets). Portfolio securities may be lent to unaffiliated broker-dealers and other unaffiliated qualified financial institutions provided that such loans are callable at any time on not more than five business days' notice and that cash or other liquid assets equal to at least 102% of the market value of the securities loaned, determined daily, is deposited by the borrower with the Fund and is maintained each business day. While such securities are on loan, the borrower pays the Fund any income accruing thereon. The Fund may invest any cash collateral, thereby earning additional income, and may receive an agreed-upon fee from the borrower. Borrowed securities must be returned when the loan terminates. Any gain or loss in the market value of the borrowed securities that occurs during the term of the loan belongs to the Fund and its shareholders. The Fund pays reasonable administrative, custodial, and other fees in connection with such loans and may pay a negotiated portion of the interest earned on the cash or government securities pledged as collateral to the borrower or placing broker. The Fund does not normally retain voting rights attendant to securities it has lent, but it may call a loan of securities in anticipation of an important vote.

Short Sales

A short sale involves the sale by the fund of a security that it does not own with the expectation of covering settlement by purchasing the same security at a later date at a lower price. The fund may also enter into a short position by using a derivative instrument, such as a future, forward, or swap agreement. If the price of the security or derivative increases prior to the time the fund is required to replace the borrowed security, then the fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to the broker. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the value of the investment.

A “short sale against the box” is a technique that involves selling either a security owned by the fund, or a security equivalent in kind and amount to the security sold short that the fund has the right to obtain, at no additional cost, for delivery at a specified date in the future. The Fund may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities. If the value of the securities sold short against the box increases prior to the scheduled delivery date, a fund will lose money.

Foreign Currency Transactions

The Fund may engage in foreign currency transactions for both hedging and investment purposes. In addition, certain of the Fund’s investments will be denominated in foreign currencies or traded in securities markets in which settlements are made in foreign currencies. Any income on such investments is generally paid to the Fund in foreign currencies. The value of these foreign currencies relative to the U.S. dollar varies continually, causing changes in the dollar value of a fund’s portfolio investments (even if the local market price of the investments is unchanged) and changes in the dollar value of a fund’s income available for distribution to its shareholders. The effect of changes in the dollar value of a foreign currency on the dollar value of a fund’s assets and on the net investment income available for distribution may be favorable or unfavorable. The Fund may also use foreign currency transactions to increase exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another.

The Fund may incur costs in connection with conversions between various currencies. In addition, the Fund may be required to liquidate portfolio assets, or may incur increased currency conversion costs, to compensate for a decline in the dollar value of a foreign currency occurring between the time when the Fund declares and pays a dividend, or between the time when the Fund accrues and pays an operating expense in U.S. dollars.

To protect against a change in the foreign currency exchange rate between the date on which the Fund contracts to purchase or sell a security and the settlement date for the purchase or sale, to gain exposure to one or more foreign

currencies or to “lock in” the equivalent of a dividend or interest payment in another currency, the Fund might purchase or sell a foreign currency on a spot ( i.e ., cash) basis at the prevailing spot rate.

The Fund also may write options on foreign currencies. For example, to hedge against a potential decline in the U.S. dollar due to adverse fluctuations in exchange rates, the Fund could, instead of purchasing a put option, write a call option on the relevant currency. If the decline expected by the Fund occurs, the option will most likely not be exercised and the diminution in value of portfolio securities will be offset at least in part by the amount of the premium received. Similarly, instead of purchasing a call option to hedge against a potential increase in the U.S. dollar cost of securities to be acquired, the Fund could write a put option on the relevant currency which, if rates move in the manner projected by the Fund, will expire unexercised and allow the Fund to hedge the increased cost up to the amount of the premium. If exchange rates do not move in the expected direction, the option may be exercised and the Fund would be required to buy or sell the underlying currency at a loss, which may not be fully offset by the amount of the premium. Through the writing of options on foreign currencies, the Fund also may lose all or a portion of the benefits that might otherwise have been obtained from favorable movements in exchange rates.

Transactions in foreign currencies, foreign currency denominated debt and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. Transactions in non-U.S. currencies are also subject to many of the risks of investing in non-U.S. securities. Because the Fund may invest in foreign securities and foreign currencies, changes in foreign economies and political climates are more likely to affect the Fund than a mutual fund that invests exclusively in U.S. companies. There also may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. If the Fund’s portfolio is over-weighted in a certain geographic region, any negative development affecting that region will have a greater impact on the Fund than a fund that is not over-weighted in that region.

The typical use of a forward contract is to "lock in" the price of a security in U.S. dollars or some other foreign currency which the Fund is holding in its portfolio. By entering into a forward contract for the purchase or sale, for a fixed amount of dollars or other currency, of the amount of foreign currency involved in the underlying security transactions, the Fund may be able to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar or other currency which is being used for the security purchase and the

foreign currency in which the security is denominated in or exposed to during the period between the date on which the security is purchased or sold and the date on which payment is made or received.

The Sub-Advisor also may from time to time utilize forward contracts for other purposes. For example, they may be used to hedge a foreign security held in the portfolio or a security which pays out principal tied to an exchange rate between the U.S. dollar and a foreign currency, against a decline in value of the applicable foreign currency. They also may be used to lock in the current exchange rate of the currency in which those securities anticipated to be purchased are denominated in or exposed to. At times, the Fund may enter into "cross-currency" hedging transactions involving currencies other than those in which securities are held or proposed to be purchased are denominated.

The Fund segregates liquid assets in an amount equal to (1) at least its daily marked-to-market (net) obligation (i.e., its daily net liability, if any) with respect to forward currency contracts that are cash settled and (2) the net notional value with respect to forward currency contracts that are not cash settled. It should be noted that the use of forward foreign currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities. It simply establishes a rate of exchange between the currencies that can be achieved at some future point in time. Additionally, although such contracts tend to minimize the risk of loss due to a decline in the value of the hedged currency, they also tend to limit any potential gain that might result if the value of the currency increases.

Currency hedging involves some of the same risks and considerations as other transactions with similar instruments. Currency transactions can result in losses to the Fund if the currency being hedged fluctuates in value to a degree or in a direction that is not anticipated. Further, the risk exists that the perceived linkage between various currencies may not be present or may not be present during the particular time that the Fund is engaging in currency hedging. Currency transactions are also subject to risks different from those of other portfolio transactions. Because currency control is of great importance to the issuing governments and influences economic planning and policy, purchases and sales of currency and related instruments can be adversely affected by government exchange controls, limitations or restrictions on repatriation of currency, and manipulations or exchange restrictions imposed by governments. These forms of governmental actions can result in losses to the Fund if it is unable to deliver or receive currency or monies in settlement of obligations. They could also cause hedges the Fund has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Currency exchange rates may also fluctuate based on factors extrinsic to a country's economy. Buyers and sellers of currency forward contracts are subject to the same risks that apply to the use of forward contracts generally. Further, settlement of a currency forward contract for the purchase of most currencies must occur at a bank based in the issuing nation. The ability to establish and close out positions on trading options on currency futures contracts is subject to the maintenance of a liquid market that may not always be available.

Moreover, the Fund bears the risk of loss of the amount expected to be received under a forward contract in the event of the default or bankruptcy of a forward counterparty.

Repurchase and Reverse Repurchase Agreements, Mortgage Dollar Rolls and Sale-Buybacks

The Fund may invest in repurchase and reverse repurchase agreements. In a repurchase agreement, the Fund purchases a security and simultaneously commits to resell that security to the seller at an agreed upon price on an agreed upon date within a number of days (usually not more than seven) from the date of purchase. The resale price consists of the purchase price plus an amount that is unrelated to the coupon rate or maturity of the purchased security. A repurchase agreement involves the obligation of the seller to pay the agreed upon price, which obligation is in effect secured by the value (at least equal to the amount of the agreed upon resale price and marked-to-market daily) of the underlying security or "collateral." A risk associated with repurchase agreements is the failure of the seller to repurchase the securities as agreed, which may cause the Fund to suffer a loss if the market value of such securities declines before they can be liquidated on the open market. In the event of bankruptcy or insolvency of the seller, the Fund may encounter delays and incur costs in liquidating the underlying security. Repurchase agreements that mature in more than seven days are subject to the Fund's limit on illiquid investments. While it is not possible to eliminate all risks from these transactions, it is the policy of the Fund to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory by the Sub-Advisor.

The Fund may use reverse repurchase agreements, mortgage dollar rolls, and economically similar transactions to obtain cash to satisfy unusually heavy redemption requests or for other temporary or emergency purposes without the necessity of selling portfolio securities, or to earn additional income on portfolio securities, such as Treasury bills or notes. In a reverse repurchase agreement, the Fund sells a portfolio security to another party, such as a bank or broker-dealer, in return for cash and agrees to repurchase the instrument at a particular price and time. While a reverse repurchase agreement is outstanding, the Fund will maintain cash or appropriate liquid assets to cover its

obligation under the agreement. The Fund will enter into reverse repurchase agreements only with parties that the Sub-Advisor deems creditworthy. Using reverse repurchase agreements to earn additional income involves the risk that the interest earned on the invested proceeds is less than the expense of the reverse repurchase agreement transaction. This technique may also have a leveraging effect on the Fund, although the Fund's intent to segregate assets in the amount of the reverse repurchase obligation minimizes this effect.

A “mortgage dollar roll” is similar to a reverse repurchase agreement in certain respects. In a “dollar roll” transaction the Fund sells a mortgage-related security, such as a security issued by the Government National Mortgage Association, to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a pre-determined price. A dollar roll can be viewed, like a reverse repurchase agreement, as a collateralized borrowing in which the Fund pledges a mortgage-related security to a dealer to obtain cash. Unlike in the case of reverse repurchase agreements, the dealer with which the Fund enters into a dollar roll transaction is not obligated to return the same securities as those originally sold by the Fund, but only securities which are “substantially identical.” To be considered “substantially identical,” the securities returned to the Fund generally must: 1) be collateralized by the same types of underlying mortgages; 2) be issued by the same agency and be part of the same program; 3) have a similar original stated maturity; 4) have identical net coupon rates; 5) have similar market yields (and therefore price); and 6) satisfy “good delivery” requirements, meaning that the aggregate principal amounts of the securities delivered and received back must be within 0.01% of the initial amount delivered.

The Fund's obligations under a dollar roll agreement must be covered by segregated liquid assets equal in value to the securities subject to repurchase by the Fund.

The Fund also may effect simultaneous purchase and sale transactions that are known as “sale-buybacks.” A sale-buyback is similar to a reverse repurchase agreement, except that in a sale-buyback, the counterparty who purchases the security is entitled to receive any principal or interest payments made on the underlying security pending settlement of the Fund's repurchase of the underlying security. The Fund's obligations under a sale-buyback typically would be offset by liquid assets equal in value to the amount of the Fund's forward commitment to repurchase the subject security.

Swap Agreements and Options on Swap Agreements

The Fund may engage in swap transactions, including, but not limited to, swap agreements on interest rates, security or commodity indexes, specific securities and commodities, and credit and event-linked swaps, to the extent permitted by its investment restrictions. To the extent the Fund may invest in foreign currency-denominated securities, it may also invest in currency swap agreements and currency exchange rate swap agreements. The Fund may also enter into options on swap agreements (“swap options”).

The Fund may enter into swap transactions for any legal purpose consistent with its investment objectives and policies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets; to protect against currency fluctuations; as a duration management technique; to protect against any increase in the price of securities

The Fund anticipates purchasing at a later date; to gain exposure to one or more securities, currencies, or interest rates; to take advantage of perceived mispricing in the securities markets; or to gain exposure to certain markets in the most economical way possible.

Swap agreements are two party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or "swapped" between the parties are generally calculated with respect to a "notional amount," i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a "basket" of securities or commodities representing a particular index.

Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (for example, an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal). Forms of swap agreements also include interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or "cap"; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or "floor"; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. A currency swap is an agreement to exchange cash flows on a notional amount based on changes in the relative values of the specified currencies. An index swap is an agreement to make or receive

payments based on the different returns that would be achieved if a notional amount were invested in a specified basket of securities (such as the S&P 500 Index) or in some other investment (such as U.S. Treasury Securities). A total return swap is an agreement to make payments of the total return from a specified asset or instrument (or a basket of such instruments) during the specified period, in return for payments equal to a fixed or floating rate of interest or the total return from another specified asset or instrument. Alternatively, a total return swap can be structured so that one party will make payments to the other party if the value of the relevant asset or instrument increases, but receive payments from the other party if the value of that asset or instrument decreases. Consistent with the Fund's investment objectives and general investment policies, it may invest in commodity swap agreements. For example, an investment in a commodity swap agreement may involve the exchange of floating-rate interest payments for the total return on a commodity index. In a total return commodity swap, the Fund will receive the price appreciation of a commodity index, a portion of the index, or a single commodity in exchange for paying an agreed-upon fee. If the commodity swap is for one period, the Fund may pay a fixed fee, established at the outset of the swap. However, if the term of the commodity swap is for more than one period, with interim swap payments, the Fund may pay an adjustable or floating fee. With a "floating" rate, the fee may be pegged to a base rate, such as the London Interbank Offered Rate, and is adjusted each period. Therefore, if interest rates increase over the term of the swap contract, the Fund may be required to pay a higher fee at each swap reset date.

The Fund may enter into credit default swap agreements. The "buyer" in a credit default contract is obligated to pay the "seller" a periodic stream of payments over the term of the contract provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or "par value," of the reference obligation in exchange for the reference obligation. The Fund may be either the buyer or seller in a credit default swap transaction. If the Fund is a buyer and no event of default occurs, the Fund will lose its investment and recover nothing. However, if an event of default occurs, the Fund (if the buyer) will receive the full notional value of the reference obligation that may have little or no value. As a seller, the Fund receives a fixed rate of income throughout the term of the contract, which typically is between six months and three years, provided that there is no default event. If an event of default occurs, the seller must pay the buyer the full notional value of the reference obligation. In addition, collateral posting requirements are individually negotiated and there is no regulatory requirement that a counterparty post collateral to secure its obligations or a specified amount of cash, depending upon the terms of the swap, under a credit default swap. Furthermore, there is no requirement that a party be informed in advance when a credit default swap agreement is sold. Accordingly, the Fund may have difficulty identifying the party responsible for payment of its claims. The notional value of credit default swaps with respect to a particular investment is often larger than the total par value of such investment outstanding and, in event of a default, there may be difficulties in making the required deliveries of the reference investments, possibly delaying payments.

The Fund may invest in derivative instruments that provide exposure to one or more credit default swaps. For example, the Fund may invest in a derivative instrument known as the Loan-Only Credit Default Swap Index (“LCDX”), a tradable index with 100 equally-weighted underlying single-name loan-only credit default swaps (“LCDS”). Each underlying LCDS references an issuer whose loans trade in the secondary leveraged loan market. The Fund can either buy the index (take on credit exposure) or sell the index (pass credit exposure to a counterparty). While investing in these types of derivatives will increase the universe of debt securities to which the Fund is exposed, such investments entail additional risks that are not typically associated with investments in other debt securities. Credit default swaps and other derivative instruments related to loans are subject to the risks associated with loans generally, as well as the risks of derivative transactions.

The Fund may invest in publicly or privately issued interests in investment pools whose underlying assets are credit default, credit-linked, interest rate, currency exchange, equity-linked or other types of swap contracts and related underlying securities or securities loan agreements. The pools’ investment results may be designed to correspond generally to the performance of a specified securities index or “basket” of securities, or sometimes a single security. These types of pools are often used to gain exposure to multiple securities with a smaller investment than would be required to invest directly in the individual securities. They also may be used to gain exposure to foreign securities markets without investing in the foreign securities themselves and/or the relevant foreign market. To the extent that the Fund invests in pools of swaps and related underlying securities or securities loan agreements whose return corresponds to the performance of a foreign securities index or one or more foreign securities, investing in such pools will involve risks similar to the risks of investing in foreign securities. In addition to the risks associated with investing in swaps generally, the Fund bears the risks and costs generally associated with investing in pooled investment vehicles, such as paying the fees and expenses of the pool and the risk that the pool or the operator of the pool may default on its obligations to the holder of interests in the pool, such as the Fund. Interests in privately offered investment pools of swaps may be considered illiquid.

The Fund may enter into contracts for differences. “Contracts for differences” are swap arrangements in which the Fund may agree with a counterparty that its return (or loss) will be based on the relative performance of two different groups or “baskets” of securities. For example, as to one of the baskets, the Fund’s return is based on theoretical long futures positions in the securities comprising that basket, and as to the other basket, the Fund’s return is based on theoretical short futures positions in the securities comprising that other basket. The notional sizes of the baskets will not necessarily be the same, which can give rise to investment leverage. The Fund may also use actual long and short futures positions to achieve the market exposure(s) as contracts for differences. The Fund may enter into swaps and contracts for differences for investment return, hedging, risk management and for investment leverage.

A swap option (also known as “swaptions”) is a contract that gives a counterparty the right (but not the obligation) in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement, at some designated future time on specified terms. The buyer and seller of the swap option agree on the strike price, length of the option period, the term of the swap, notional amount, amortization and frequency of settlement. The Fund may engage in swap options for hedging purposes or in an attempt to manage and mitigate credit and interest rate risk. The Fund may write (sell) and purchase put and call swap options. The use of swap options involves risks, including, among others, imperfect correlation between movements of the price of the swap options and the price of the securities, indices or other assets serving as reference instruments for the swap option, reducing the effectiveness of the instrument for hedging or investment purposes.

The swap agreements the Fund enters into settle in cash and, therefore, provide for calculation of the obligations of the parties to the agreement on a “net basis.” Consequently, the Fund's current obligations (or rights) under such a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). The Fund's current obligations under such a swap agreement will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the segregation of assets determined to be liquid by the Manager or Sub-Advisor in accordance with procedures established by the Board of Directors, to avoid any potential leveraging of the Fund's portfolio. Obligations under swap agreements for which the Fund segregates assets will not be construed to be “senior securities” for purposes of the Fund's investment restriction concerning senior securities.

Swaps can be highly volatile and may have a considerable impact on the Fund’s performance, as the potential gain or loss on any swap transaction is not subject to any fixed limit. Whether the Fund's use of swap agreements or swap options will be successful in furthering its investment objective of total return will depend on the ability of the Fund's Manager or Sub-Advisor to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Because they are two party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The Fund will enter into swap agreements only with counterparties that present minimal credit risks, as determined by the Fund's Manager or Sub-Advisor. Certain restrictions imposed on the Fund by the Internal Revenue Code may limit the Fund’s ability to use swap agreements.

Depending on the terms of the particular option agreement, the Fund will generally incur a greater degree of risk when it writes a swap option than it will incur when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Liquidity. Some swap markets have grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, these swap markets have become relatively liquid.

The liquidity of swap agreements will be determined by the Manager or Sub-Advisor based on various factors, including:

Such determination will govern whether a swap will be deemed to be within the Fund's restriction on investments in illiquid securities.

For purposes of applying the Fund’s investment policies and restrictions (as stated in the Prospectuses and this Statement of Additional Information) swap agreements are generally valued by the Fund at market value. In the case of a credit default swap, however, in applying certain of the Fund’s investment policies and restrictions the Fund will value the credit default swap at its notional value or its full exposure value (i.e., the sum of the notional amount for the contract plus the market value), but may value the credit default swap at market value for purposes of applying certain of the Fund’s other investment policies and restrictions. For example, the Fund may value credit default swaps at full exposure value for purposes of the Fund’s credit quality guidelines because such value reflects the Fund’s actual economic exposure during the term of the credit default swap agreement. In this context, both the notional amount and the market value may be positive or negative depending on whether the fund is selling or buying protection through the credit default swap. The manner in which certain securities or other instruments are valued by the Fund for purposes of applying investment policies and restrictions may differ from the manner in which those investments are valued by other types of investors.

Money Market Instruments/Temporary Defensive Position

The Fund may make money market investments (cash equivalents), without limit, pending other investment or settlement, for liquidity, or in adverse market conditions. Following are descriptions of the types of money market instruments that the Fund may purchase:

Some obligations issued or guaranteed by U.S. government agencies and instrumentalities are supported by the full faith and credit of the U.S. Treasury. Others, such as those issued by the Federal National Mortgage Association, are supported by discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality. Still others, such as those issued by the Student Loan Marketing Association, are supported only by the credit of the agency or instrumentality.

Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers’ acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are “accepted” by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits.

Obligations of foreign banks and obligations of overseas branches of U.S. banks are subject to somewhat different regulations and risks than those of U.S. domestic banks. For example, an issuing bank may be able to maintain that the liability for an investment is solely that of the overseas branch which could expose the Fund to a greater risk of loss. In addition, obligations of foreign banks or of overseas branches of U.S. banks may be affected by governmental action in the country of domicile of the branch or parent bank. Examples of adverse foreign governmental actions include the imposition of currency controls, the imposition of withholding taxes on interest income payable on such obligations, interest limitations, seizure or nationalization of assets, or the declaration of a moratorium. Deposits in foreign banks or foreign branches of U.S. banks are not covered by the Federal Deposit Insurance Corporation and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to United States banks. Foreign banks are not generally subject to examination by any United States Government agency or instrumentality. The Fund only buys short-term instruments where the risks of adverse governmental

action are believed by the Sub-Advisor to be minimal. The Fund considers these factors, along with other appropriate factors, in making an investment decision to acquire such obligations. It only acquires those which, in the opinion of management, are of an investment quality comparable to other debt securities bought by the Fund.

A certificate of deposit is issued against funds deposited in a bank or savings and loan association for a definite period of time, at a specified rate of return. Normally they are negotiable. However, the Fund occasionally may invest in certificates of deposit which are not negotiable. Such certificates may provide for interest penalties in the event of withdrawal prior to their maturity. A bankers' acceptance is a short-term credit instrument issued by corporations to finance the import, export, transfer, or storage of goods. They are termed "accepted" when a bank guarantees their payment at maturity and reflect the obligation of both the bank and drawer to pay the face amount of the instrument at maturity.

The ratings of nationally recognized statistical rating organization ("NRSRO"), such as Moody's Investor Services, Inc. ("Moody's") and Standard & Poor's ("S&P"), which are described in Appendix B, represent their opinions as to the quality of the money market instruments which they undertake to rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. These ratings, including ratings of NRSROs other than Moody's and S&P, are the initial criteria for selection of portfolio investments, but the Sub-Advisor further evaluates these securities.

Municipal Obligations

Municipal Obligations are obligations issued by or on behalf of states, territories, and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, including municipal utilities, or multi-state agencies or authorities. The interest on Municipal Obligations is exempt from federal income tax in the opinion of bond counsel to the issuer. Three major classifications of Municipal Obligations are: Municipal Bonds, that generally have a maturity at the time of issue of one year or more; Municipal Notes, that generally have a maturity at the time of issue of six months to three years; and Municipal Commercial Paper, that generally has a maturity at the time of issue of 30 to 270 days.

The term "Municipal Obligations" includes debt obligations issued to obtain funds for various public purposes, including the construction of a wide range of public facilities such as airports, bridges, highways, housing, hospitals, mass transportation, schools, streets, water and sewer works, and electric utilities. Other public purposes for which Municipal Obligations are issued include refunding outstanding obligations, obtaining funds for general operating expenses, and lending such funds to other public institutions and facilities. To the extent that a fund invests a significant portion of its assets in municipal obligations issued in connection with a single project, the fund likely will be affected by the economic, business or political environment of the project.

AMT-Subject Bonds. Industrial development bonds are issued by or on behalf of public authorities to obtain funds to provide for the construction, equipment, repair or improvement of privately operated housing facilities, sports facilities, convention or trade show facilities, airport, mass transit, industrial, port or parking facilities, air or water pollution control facilities, and certain local facilities for water supply, gas, electricity, or sewage or solid waste disposal. They are considered to be Municipal Obligations if the interest paid thereon qualifies as exempt from federal income tax in the opinion of bond counsel to the issuer, even though the interest may be subject to the federal alternative minimum tax.

personal property so financed as security for such payment. Funds may also invest in "moral obligation" bonds that are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its obligations, the repayment of the bonds becomes a moral commitment but not a legal obligation of the state or municipality in question.

The fund's right to obtain payment at par on a demand instrument upon demand could be affected by events occurring between the date the fund elects to redeem the instrument and the date redemption proceeds are

due which affects the ability of the issuer to pay the instrument at par value. The Sub-Advisor monitors on an ongoing basis the pricing, quality, and liquidity of such instruments and similarly monitors the ability of an issuer of a demand instrument, including those supported by bank letters of credit or guarantees, to pay principal and interest on demand. Although the ultimate maturity of such variable rate obligations may exceed one year, the fund treats the maturity of each variable rate demand obligation as the longer of a) the notice period required before the fund is entitled to payment of the principal amount through demand or b) the period remaining until the next interest rate adjustment. Floating rate instruments with demand features are deemed to have a maturity equal to the period remaining until the principal amount can be recovered through demand.

The Fund may purchase participation interests in variable rate Municipal Obligations (such as industrial development bonds). A participation interest gives the purchaser an undivided interest in the Municipal Obligation in the proportion that its participation interest bears to the total principal amount of the Municipal Obligation. The Fund has the right to demand payment on seven days' notice, for all or any part of the Fund's participation interest in the Municipal Obligation, plus accrued interest. Each participation interest is backed by an irrevocable letter of credit or guarantee of a bank. Banks will retain a service and letter of credit fee and a fee for issuing repurchase commitments in an amount equal to the excess of the interest paid on the Municipal Obligations over the negotiated yield at which the instruments were purchased by the Fund.

The amount payable to the Fund upon its exercise of a stand-by commitment normally would be 1) the acquisition cost of the municipal security (excluding any accrued interest that the fund paid on the acquisition), less any amortized market premium or plus any amortized market or original issue discount during the period the fund owned the security, plus, 2) all interest accrued on the security since the last interest payment date during the period the security was owned by the fund. Absent unusual circumstances, the fund would value the underlying municipal security at amortized cost. As a result, the amount payable by the broker-dealer, dealer or bank during the time a stand-by commitment is exercisable would be substantially the same as the value of the underlying municipal obligation.

The Fund’s right to exercise a stand-by commitment would be unconditional and unqualified. Although the Fund could not transfer a stand-by commitment, it could sell the underlying municipal security to a third party at any time. It is expected that stand-by commitments generally will be available to the Fund without the payment of any direct or indirect consideration. The Fund may, however, pay for stand-by commitments if such action is deemed necessary. In any event, the total amount paid for outstanding stand-by commitments held in the Fund's portfolio would not exceed 0.50% of the value of the Fund’s total assets calculated immediately after each stand-by commitment is acquired.

The Fund intends to enter into stand-by commitments only with broker-dealers, dealers, or banks that its Sub-Advisors believe present minimum credit risks. The Fund’s ability to exercise a stand-by commitment will depend upon the ability of the issuing institution to pay for the underlying securities at the time the stand-by commitment is exercised. The credit of each institution issuing a stand-by commitment to a fund will be evaluated on an ongoing basis by the Sub-Advisor.

The Fund intends to acquire stand-by commitments solely to facilitate portfolio liquidity and does not intend to exercise its right thereunder for trading purposes. The acquisition of a stand-by commitment would not affect the valuation of the underlying municipal security. Each stand-by commitment will be valued at zero in determining net asset value. Should the Fund pay directly or indirectly for a stand-by commitment, its costs will be reflected in realized gain or loss when the commitment is exercised or expires. The maturity of a municipal security purchased by the Fund will not be considered shortened by any stand-by commitment to which the obligation is subject. Thus, stand-by commitments will not affect the dollar-weighted average maturity of the Fund's portfolio.

Municipal Obligations are subject to the provisions of bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Act. They are also subject to federal or state laws, if any, which extend the time for payment of principal or interest, or both, or impose other constraints upon enforcement of such obligations or upon municipalities to levy taxes. The power or ability of issuers to pay, when due, principal of and interest on Municipal Obligations may also be materially affected by the results of litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Obligations. It may be expected that similar proposals will be introduced in the future. If such a proposal was enacted, the ability of the Fund to pay "exempt interest" dividends may be adversely affected. The Fund would reevaluate its investment objective and policies and consider changes in its structure.

Other Investment Companies

The Fund may invest in the securities of investment companies, subject to its fundamental and non-fundamental investment restrictions. Securities of other investment companies, including shares of closed-end investment companies, unit investment trusts, various exchange-traded funds ("ETFs"), and other open-end investment companies, represent interests in professionally managed portfolios that may invest in a variety of instruments. Certain types of investment companies, such as closed-end investment companies, issue a fixed number of shares that trade on a stock exchange or over-the-counter at a premium or a discount to their net asset value. Others are continuously offered at net asset value, but may also be traded in the secondary market. ETFs are often structured to perform in a similar fashion to a broad-based securities index. Investing in ETFs involves generally the same risks as investing directly in the underlying instruments. Investing in ETFs involves the risk that they will not perform in exactly the same fashion, or in response to the same factors, as the index or underlying instruments. Shares of ETFs may trade at prices other than NAV.

As a shareholder in an investment company, the Fund would bear its ratable share of that entity's expenses, including its advisory and administrative fees. The Fund would also continue to pay its own advisory fees and other expenses. Consequently, the Fund and its shareholders would, in effect, absorb two levels of fees with respect to investments in other investment companies.

Bank Loans (also known as Senior Floating Rate Interests)

Bank loans typically hold the most senior position in the capital structure of a business entity (the “Borrower”), are typically secured by specific collateral, and have a claim on the assets and/or stock of the Borrower that is senior to that held by unsecured subordinated debtholders and stockholders of the Borrower. Bank loans are typically structured and administered by a financial institution that acts as the agent of the lenders participating in the bank loan. Bank loans are typically rated below-investment-grade, which means they are more likely to default than investment-grade loans (they could also be unrated but of comparable quality). A default could lead to non-payment of income which would result in a reduction of income to the Fund and there can be no assurance that the liquidation of any collateral would satisfy the Borrower’s obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated.

The primary and secondary market for bank loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may cause the Fund to be unable to realize full value and thus cause a material decline in the fund's net asset value.

Bank loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or the London InterBank Offered Rate (LIBOR) or the prime rate offered by one or more major United States banks.

Bank loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for the Borrower to repay, prepayments of senior floating rate interests may occur.

Variable and Floating Rate Instruments

The Fund may purchase variable and floating rate instruments. These instruments may include variable amount master demand notes that permit the indebtedness thereunder to vary in addition to providing for periodic adjustments

in the interest rate. These instruments may also include leveraged inverse floating rate debt instruments, or “inverse floaters”. The interest rate of an inverse floater resets in the opposite direction from the market rate of interest on a security or interest to which it is related. An inverse floater may be considered to be leveraged to the extent that its interest rate varies by a magnitude that exceeds the magnitude of the change in the index rate of interest, and is subject to many of the same risks as derivatives. The higher degree of leverage inherent in inverse floaters is associated with greater volatility in their market values. Certain of these investments may be illiquid. The absence of an active secondary market with respect to these investments could make it difficult for the Fund to dispose of a variable or floating rate note if the issuer defaulted on its payment obligation or during periods that the Fund is not entitled to exercise its demand rights, and the Fund could, for these or other reasons, suffer a loss with respect to such instruments.

Pay-in-Kind Securities

The Fund may invest in pay-in-kind securities. Pay-in-kind securities pay dividends or interest in the form of additional securities of the issuer, rather than in cash. These securities are usually issued and traded at a discount from their face amounts. The amount of the discount varies depending on various factors, such as the time remaining until maturity of the securities, prevailing interest rates, the liquidity of the security and the perceived credit quality of the issuer. The market prices of pay-in-kind securities generally are more volatile than the market prices of securities that pay interest periodically and are likely to respond to changes in interest rates to a greater degree than are other types of securities having similar maturities and credit quality.

Preferred Securities

There are two basic types of preferred securities, traditional preferred securities and hybrid or trust preferred securities.

Preferred securities may be issued by trusts (likely one that is wholly-owned by a financial institution or other corporate entity, typically a bank holding company) or other special purpose entities established by operating companies, and are therefore not direct obligations of operating companies. The financial institution creates the trust and owns the trust’s common securities. The trust uses the sale proceeds of its preferred securities to purchase, for example, subordinated debt issued by the financial institution. The financial institution uses the proceeds from the subordinated debt sale to increase its capital while the trust receives periodic interest payments from the financial institution for holding the subordinated debt. The Trust uses the funds received to make dividend payments to the holders of the trust preferred securities. The primary advantage of this structure may be that the trust preferred securities are treated by the financial institution as debt securities for tax purposes and as equity for the calculation of capital requirements.

Trust preferred securities typically bear a market rate coupon comparable to interest rates available on debt of a similarly rated issuer. Typical characteristics include long-term maturities, early redemption by the issuer, periodic fixed or variable interest payments, and maturities at face value. Holders of trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the financial institution. The market value of trust preferred securities may be more volatile than those of conventional debt securities. Trust preferred securities may be issued in reliance on Rule 144A under the 1933 Act and subject to restrictions on resale. There can be no assurance as to the liquidity of trust preferred securities and the ability of holders, such

as the Fund, to sell its holdings. The condition of the financial institution can be looked to identify the risks of trust preferred securities as the trust typically has no business operations other than to issue the trust preferred securities. If the financial institution defaults on interest payments to the trust, the trust will not be able to make dividend payments to holders of its securities, such as the Fund.

Floating rate preferred securities provide for a periodic adjustment in the interest rate paid on the securities. The terms of such securities provide that interest rates are adjusted periodically based upon an interest rate adjustment index. The adjustment intervals may be regular, and range from daily up to annually, or may be event-based, such as a change in the short-term interest rate. Because of the interest rate reset feature, floating rate securities provide the Fund with a certain degree of protection against rising interest rates, although the interest rates of floating rate securities will participate in any declines in interest rates as well.

If a portion of the Fund’s income consists of dividends paid by U.S. corporations, a portion of the dividends paid by the fund may be eligible for the corporate dividends-received deduction for corporate shareholders. In addition, distributions reported by the Fund as derived from qualified dividend income (“QDI”) will be taxed in the hands of individuals at the reduced rates applicable to net capital gains, provided certain holding period and other requirements are met by both the shareholder and the fund. Dividend income that the Fund receives from REITs, if any, will generally not be treated as QDI and will not qualify for the corporate dividends-received deduction. It is unclear the extent to which distributions the Fund receives from investments in certain preferred securities will be eligible for treatment as QDI or for the corporate dividends-received deduction. The Fund cannot predict at this time what portion, if any, of its dividends will qualify for the corporate dividends-received deduction or be eligible for the reduced rates of taxation applicable to QDI.

Corporate Reorganizations

Funds may invest in securities for which a tender or exchange offer has been made or announced and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced if, in the judgment of the Sub-Advisor, there is a reasonable prospect of capital appreciation significantly greater than the brokerage and other transaction expenses involved. The primary risk of such investments is that if the contemplated transaction is abandoned, revised, delayed or becomes subject to unanticipated uncertainties, the market price of the securities may decline below the purchase price paid by the Fund.

In general, securities which are the subject of such an offer or proposal sell at a premium to their historic market price immediately prior to the announcement of the offer or proposal. However, the increased market price of such securities may discount what the stated or appraised value of the security would be if the contemplated transaction were approved or consummated. Such investments may be advantageous when the discount significantly overstates the risk of the contingencies involved; significantly undervalues the securities, assets or cash to be received by shareholders of the prospective company as a result of the contemplated transaction; or fails adequately to recognize the possibility that the offer or proposal may be replaced or superseded by an offer or proposal of greater value. The evaluation of such contingencies requires unusually broad knowledge and experience on the part of the Sub-Advisor, which must appraise not only the value of the issuer and its component businesses, but also the financial resources and business motivation of the offer or proposal as well as the dynamics of the business climate when the offer or proposal is in process.

Step-Coupon Securities

The Fund may invest in step-coupon securities. Step-coupon securities trade at a discount from their face value and pay coupon interest. The coupon rate is low for an initial period and then increases to a higher coupon rate thereafter. Market values of these types of securities generally fluctuate in response to changes in interest rates to a greater degree than conventional interest-paying securities of comparable term and quality. Under many market conditions, investments in such securities may be illiquid, making it difficult for the Fund to dispose of them or determine their current value.

“Stripped” Securities

The Fund may invest in stripped securities, which are usually structured with two or more classes that receive different proportions of the interest and principal distribution on a pool of U.S. government or foreign government securities or mortgage assets. In some cases, one class will receive all of the interest (the interest-only or “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). Stripped securities commonly have greater market volatility than other types of fixed-income securities. In the case of stripped mortgage securities, if the underlying mortgage assets experience greater than anticipated payments of principal, the Fund may fail to recoup fully its investments in IOs. Stripped securities may be illiquid. Stripped securities may be considered derivative securities.

Supranational Entities

The Fund may invest in obligations of supranational entities. A supranational entity is an entity designated or supported by national governments to promote economic reconstruction, development or trade amongst nations. Examples of supranational entities include the International Bank for Reconstruction and Development (also known as the World Bank) and the European Investment Bank. Obligations of supranational entities are subject to the risk that the governments on whose support the entity depends for its financial backing or repayment may be unable or unwilling to provide that support. Obligations of a supranational entity that are denominated in foreign currencies will also be subject to the risks associated with investments in foreign currencies.

Portfolio Turnover

Portfolio turnover is a measure of how frequently a portfolio's securities are bought and sold. The portfolio turnover rate is generally calculated as the dollar value of the lesser of a portfolio's purchases or sales of shares of securities during a given year, divided by the monthly average value of the portfolio securities during that year (excluding securities whose maturity or expiration at the time of acquisition were less than one year). For example, a portfolio reporting a 100% portfolio turnover rate would have purchased and sold securities worth as much as the monthly average value of its portfolio securities during the year.

It is not possible to predict future turnover rates with accuracy. Many variable factors are outside the control of a portfolio manager. The investment outlook for the securities in which a portfolio may invest may change as a result of unexpected developments in securities markets, economic or monetary policies, or political relationships. High market volatility may result in a portfolio manager using a more active trading strategy than might otherwise be employed. Each portfolio manager considers the economic effects of portfolio turnover but generally does not treat the portfolio turnover rate as a limiting factor in making investment decisions.

Sale of shares by investors may require the liquidation of portfolio securities to meet cash flow needs. In addition, changes in a particular portfolio's holdings may be made whenever the portfolio manager considers that a security is no longer appropriate for the portfolio or that another security represents a relatively greater opportunity. Such changes may be made without regard to the length of time that a security has been held.

Higher portfolio turnover rates generally increase transaction costs that are expenses of the Account. Active trading may generate short-term gains (losses) for taxable shareholders.

At the date of this SAI, the Fund is new and has no operating history; therefore, portfolio turnover information is not yet available.

LEADERSHIP STRUCTURE AND BOARD OF TRUSTEES

Overall responsibility for directing the business and affairs of the Trust rests with the Board of Trustees, who are elected by the Trust's shareholders. In addition to serving on the Board of Trustees, each Trustee also serves on the Board of Principal Funds, Inc. (“PFI”) and the Board of Principal Variable Contracts Funds, Inc. (“PVC”). The Board is responsible for overseeing the operations of the Trust in accordance with the provisions of the 1940 Act, other applicable laws and the Trust’s charter. The Board elects the officers of the Trust to supervise its day-to-day operations. The Board meets in regularly scheduled meetings eight times throughout the year. Board meetings may occur in-person or by telephone. In addition, the Board holds special in-person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. Board members who are Independent Trustees meet annually to consider renewal of the Trust's advisory contracts. The Board is currently composed of eleven members, nine of whom are Independent Trustees. Each Trustee has significant prior senior management and/or board experience.

The Chairman is an interested person of the Trust. The Independent Trustees of the Trust have appointed a lead Independent Trustee whose role is to review and approve, with the Chairman, the agenda for each Board meeting and facilitate communication among the Trust's Independent Trustees as well as communication between the Independent Trustees, management of the Trust and the full Board. The Trust has determined that the Board's leadership structure is appropriate given the characteristics and circumstances of the Trust, including such items as the number of series or portfolios that comprise the Trust, the net assets of the Trust, the committee structure of the Board and the distribution arrangements of the Trust. The appropriateness of this structure is enhanced by the Trust’s Board Committees, which are described below, and the allocation of responsibilities among them.

The Trustees were selected to serve and continue on the Board based upon their skills, experience, judgment, analytical ability, diligence and ability to work effectively with other Board members, a commitment to the interests of shareholders and, for each Independent Trustee, a demonstrated willingness to take an independent and questioning view of management. In addition to these general qualifications, the Board seeks members who will build upon the diversity of the Board. In addition to those qualifications, the following is a brief discussion of the specific education, experience, qualifications, or skills that led to the conclusion that each person identified below should serve as a Trustee for the Trust.

Risk oversight forms part of the Board's general oversight of the Trust and is addressed as part of various Board and Committee activities. As part of its regular oversight of the Trust, the Board, directly or through a Committee, interacts with and reviews reports from, among others, Fund management, sub-advisors, the Trust's Chief Compliance Officer, the independent registered public accounting firm for the Trust, and internal auditors for PMC or its affiliates, as appropriate, regarding risks faced by the Trust. The Board, with the assistance of Fund management and PMC, reviews investment policies and risks in connection with its review of the Trust's performance. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust's compliance program and reports to the Board regarding compliance matters for the Trust and its principal service providers. In addition, as part of the Board's periodic review of the Trust's advisory, sub-advisory and other service provider agreements, the Board may consider risk management aspects of their operations and the functions for which they are responsible. With respect to valuation, the Board oversees a PMC valuation committee comprised of the Trust’s officers and officers of PMC and has approved and periodically reviews valuation policies applicable to valuing the Trust's shares.

The Board has established the following committees and the membership of each committee to assist in its oversight functions, including its oversight of the risks the Trust faces.

Committee membership is identified on the following pages. Each committee must report its activities to the Board on a regular basis. As used in this SAI, the “Fund Complex” refers to all series of the Trust, PFI and PVC.

15(c) Committee

The Committee’s primary purpose is to assist the Board in performing the annual review of the Fund’s advisory and sub-advisory agreements pursuant to Section 15(c) of the 1940 Act. The Committee responsibilities include requesting and reviewing materials.

Audit Committee

The primary purpose of the Committee is to assist the Board in fulfilling certain of its responsibilities. The Audit Committee serves as an independent and objective party to monitor the Fund Complex's accounting policies, financial reporting and internal control system, as well as the work of the independent registered public accountants. The Audit Committee assists Board oversight of 1) the integrity of the Fund Complex's financial statements; 2) the Fund Complex's compliance with certain legal and regulatory requirements; 3) the independent registered public accountants' qualifications and independence; and 4) the performance of the Fund Complex's independent registered public accountants. The Audit Committee also provides an open avenue of communication among the independent registered public accountants, the Manager's internal auditors, Fund Complex management, and the Board.

Executive Committee

The Committee's primary purpose is to exercise certain powers of the Board when the Board is not in session. When the Board is not in session, the Committee may exercise all powers of the Board in the management of the business of the Fund Complex except the power to 1) authorize dividends or distributions on stock; 2) issue stock, except as permitted by law 3) recommend to the stockholders any action which requires stockholder approval; 4) amend the bylaws; or 5) approve any merger or share exchange which does not require stockholder approval.

Nominating and Governance Committee

The Committee’s primary purpose is to oversee the structure and efficiency of the Board and the committees established by the Board. The Committee responsibilities include evaluating Board membership and functions, committee membership and functions, insurance coverage, and legal matters.

The nominating functions of the Nominating and Governance Committee include selecting and nominating all candidates who are not "interested persons" of the Fund Complex for election to the Board. Generally, the Committee requests trustee nominee suggestions from the committee members and management. In addition, the Committee will consider Trustee candidates recommended by shareholders of the Fund Complex. Recommendations should be submitted in writing to Principal Exchange-Traded Funds at 655 9th Street, Des Moines, Iowa 50392. When evaluating a person as a potential nominee to serve as an Independent Trustee, the Committee will generally consider, among other factors: age; education; relevant business experience; geographical factors; whether the person is "independent" and otherwise qualified under applicable laws and regulations to serve as a trustee; and whether the person is willing to serve, and willing and able to commit the time necessary for attendance at meetings and the performance of the duties of an independent trustee. The Committee also meets personally with the nominees and conducts a reference check. The final decision is based on a combination of factors, including the strengths and the experience an individual may bring to the Board. The Committee believes the Board generally benefits from diversity of background, experience and views among its members, and considers these factors in evaluating the composition of the Board. The Board does not use regularly the services of any professional search firms to identify or evaluate or assist in identifying or evaluating potential candidates or nominees.

Operations Committee

The Committee's primary purpose is to oversee the provision of administrative and distribution services to the Fund Complex, communications with the Fund Complex's shareholders, and review and oversight of the Fund Complex's operations.

The Distributor will deliver a prospectus to persons purchasing Shares in Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor has no role in determining the investment policies of the Fund or which securities are to be purchased or sold by the Fund.

The Board of Trustees of the Trust has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with its Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to finance activities primarily intended to result in the sale of Creation Units of the Fund or the provision of investor services. No Rule 12b-1 fees are currently paid by the Fund and there are no plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, they will be paid out of the respective Fund’s assets, and over time, these fees will increase the cost of your investment and they may cost you more than certain other types of sales charges.

Principal and its affiliates may, out of their own resources, pay amounts to third parties for distribution or marketing services on behalf of the Fund. The making of these payments could create a conflict of interest for a financial intermediary receiving such payments.

Fund Sub-Administrator, Custodian, and Transfer Agent

[ ] the “Transfer Agent” or the “Custodian”) serves as Fund’s sub-administrator, custodian and transfer agent. [ ] is located at [ ].

Under a Fund Administration and Accounting Agreement with the Principal (on behalf of the Fund), [ ] provides necessary administrative treasury, and tax services, including financial reporting for the maintenance and operations of the Fund. In addition, [ ] makes available the office space, equipment, personnel and facilities required to provide such services. Principal is ultimately responsible for such services pursuant to a Management Agreement with the Fund.

Under the Custody Agreement with the Trust, [ ] maintains in separate accounts cash, securities and other assets of the Trust and the Fund, keeps all necessary accounts and records, and provides other services. [ ] is required, upon order of the Trust, to deliver securities held by [ ] and to make payments for securities purchased by the Trust for the Fund. Under the Custody Agreement, [ ] is also authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the United States. [ ] also provides fund accounting services and is responsible for maintaining the books and records and calculating the daily net asset value of the Fund.

Pursuant to a Transfer Agency Services Agreement with the Trust, [ ] acts as transfer agent to the Fund, dividend disbursing agent and shareholder servicing agent to the Fund.

The Trust compensates [ ] for the Custody and Transfer Agency services. The Fund is newly formed and has not paid any fees for the services set forth above as of the date of this SAI.

Brokerage on Purchases and Sales of Securities

All orders for the purchase or sale of portfolio securities are placed on behalf of the Fund by the Fund's Sub-Advisor pursuant to the terms of the applicable sub-advisory agreement. In distributing brokerage business arising out of the placement of orders for the purchase and sale of securities for any Fund, the objective of the Fund's Sub-Advisor is to obtain the best overall terms. In pursuing this objective, the Sub-Advisor considers all matters it deems relevant, including the breadth of the market in the security, the price of the security, the financial condition and executing capability of the broker or dealer, confidentiality, including trade anonymity, and the reasonableness of the commission, if any (for the specific transaction and on a continuing basis). This may mean in some instances that the Sub-Advisor will pay a broker commissions that are in excess of the amount of commissions another broker might have charged for executing the same transaction when the Sub-Advisor believes that such commissions are reasonable in light of a) the size and difficulty of the transaction, b) the quality of the execution provided, and c) the level of commissions paid relative to commissions paid by other institutional investors. (Such factors are viewed both in terms of that particular transaction and in terms of all transactions that broker executes for accounts over which the Sub-Advisor exercises investment discretion. The Board has also adopted a policy and procedure designed to prevent the Fund from compensating a broker/dealer for promoting or selling Fund shares by directing brokerage transactions to that broker/dealer for the purpose of compensating the broker/dealer for promoting or selling Fund shares. Therefore, the Sub-Advisor may not compensate a broker/dealer for promoting or selling Fund shares by directing

brokerage transactions to that broker/dealer for the purpose of compensating the broker/dealer for promoting or selling Fund shares. A Sub-Advisor may purchase securities in the over-the-counter market, utilizing the services of principal market makers unless better terms can be obtained by purchases through brokers or dealers, and may purchase securities listed on the NYSE from non-Exchange members in transactions off the Exchange.)

A Sub-Advisor may give consideration in the allocation of business to services performed by a broker (e.g., the furnishing of statistical data and research generally consisting of, but not limited to, information of the following types: analyses and reports concerning issuers, industries, economic factors and trends, portfolio strategy, performance of client accounts, and access to research analysts, corporate management personnel, and industry experts). If any such allocation is made, the primary criteria used will be to obtain the best overall terms for such transactions or terms that are reasonable in relation to the research or brokerage services provided by the broker or dealer when viewed in terms of either a particular transaction or the sub-advisor’s overall responsibilities to the accounts under its management. The Sub-Advisor generally pays additional commission amounts for such research services. Statistical data and research information received from brokers or dealers as described above may be useful in varying degrees and the Sub-Advisor may use it in servicing some or all of the accounts it manages.

Subject to the rules promulgated by the SEC, as well as other regulatory requirements, the Board has approved procedures whereby the Fund may purchase securities that are offered in underwritings in which an affiliate of a Sub-Advisor, or Principal, participates. These procedures prohibit the Fund from directly or indirectly benefiting a Sub-Advisor affiliate or a Manager affiliate in connection with such underwritings. In addition, for underwritings where a Sub-Advisor affiliate or a Manager participates as a principal underwriter, certain restrictions may apply that could, among other things, limit the amount of securities that the Fund could purchase in the underwritings. The Sub-Advisor shall determine the amounts and proportions of orders allocated to the Sub-Advisor or affiliate. The Trustees of the Fund will receive quarterly reports on these transactions.

The Board has approved procedures that permit the Fund to effect a purchase or sale transaction between the Fund and an affiliated mutual fund or between the Fund and affiliated persons of the Fund under limited circumstances prescribed by SEC rules. Any such transaction must be effected without any payment other than a cash payment for the securities, for which a market quotation is readily available, at the current market price; no brokerage commission or fee (except for customary transfer fees), or other remuneration may be paid in connection with the transaction. The Board receives quarterly reports of all such transactions.

The Board has also approved procedures that permit the Fund's Sub-Advisor(s) to place portfolio trades with an affiliated broker under circumstances prescribed by SEC Rules 17e-1 and 17a-10. The procedures require that total commissions, fees, or other remuneration received or to be received by an affiliated broker must be reasonable and fair compared to the commissions, fees or other remuneration received by other brokers in connection with comparable transactions involving similar securities being purchased or sold on a securities exchange during a comparable time period. The Board receives quarterly reports of all transactions completed pursuant to the Fund's procedures.

Purchases and sales of debt securities and money market instruments usually are principal transactions; portfolio securities are normally purchased directly from the issuer or from an underwriter or marketmakers for the securities. Such transactions are usually conducted on a net basis with the Fund paying no brokerage commissions. Purchases from underwriters include a commission or concession paid by the issuer to the underwriter, and the purchases from dealers serving as marketmakers include the spread between the bid and asked prices.

Commission rates a Sub-Advisor pays to brokers may vary and reflect such factors as the trading volume placed with a broker, the type of security, the market in which a security is traded and the trading volume of that security, the types of services provided by the broker (i.e. execution services only or additional research services) and the quality of a broker's execution.

Allocation of Trades

By the Sub-Advisor. The portfolio managers of each of the Sub-Advisors manage a number of accounts other than the Fund's portfolio, including in some instances proprietary or personal accounts. Managing multiple accounts may give rise to potential conflicts of interest including, for example, conflicts among investment strategies, allocation of investment opportunities and compensation for the account. Each Sub-advisor has adopted and implemented policies and procedures that it believes address the potential conflicts associated with managing accounts for multiple clients and personal accounts and are designed to ensure that all clients and client accounts are treated fairly and equitably. These procedures include allocation policies and procedures, personal trading policies and procedures, internal review processes and, in some cases, review by independent third parties.

Investments the Sub-Advisor deems appropriate for the Fund's portfolio may also be deemed appropriate by it for other accounts. Therefore, the same security may be purchased or sold at or about the same time for both the Fund's portfolio and other accounts. In such circumstances, the Sub-Advisor may determine that orders for the purchase or sale of the same security for the Fund's portfolio and one or more other accounts should be combined. In this event the transactions will be priced and allocated in a manner deemed by the Sub-Advisor to be equitable and in the best interests of the Fund’s portfolio and such other accounts. While in some instances combined orders could adversely affect the price or volume of a security, the Fund believes that its participation in such transactions on balance will produce better overall results for the Fund.

PURCHASE AND REDEMPTION OF CREATION UNITS

Book-Entry Only System

The Depository Trust Company (DTC) acts as securities depository for the shares. Shares of the Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC. Certificates will not be issued for shares.

DTC, a limited-purpose trust company, was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions among DTC participants in such securities through electronic book-entry changes in accounts of the DTC participants, thereby eliminating the need for physical movement of securities certificates. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations, some of whom (and/or their representatives) own DTC. Access to the DTC system is also available to others such as banks, brokers, dealers, and trust companies that clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly.

Beneficial ownership of shares is limited to DTC participants and persons holding interests through DTC participants. Ownership of beneficial interests in shares (owners of beneficial interests are referred to herein as Beneficial Owners) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC participants) and on the records of DTC participants (with respect to indirect DTC participants and Beneficial Owners that are not DTC participants). Beneficial Owners will receive from or through a DTC participant a written confirmation relating to their purchase of shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the trust a listing of the shares of the fund held by each DTC participant. The Trust shall inquire of each such DTC participant as to the number of Beneficial Owners holding fund shares, directly or indirectly, through such DTC participant. The Trust shall provide each such DTC participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC participant may reasonably request, so that such notice, statement or communication may be transmitted by such DTC participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC participants' accounts with payments in amounts proportionate to their respective beneficial interests in shares of the fund as shown on the records of DTC or its nominee. Payments by DTC participants to indirect DTC participants and Beneficial Owners of shares held through such DTC participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a "street name," and will be the responsibility of such DTC participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC participants or the relationship between such DTC participants and the indirect DTC participants and Beneficial Owners owning through such DTC participants.

DTC may decide to discontinue providing its service with respect to shares at any time by giving reasonable notice to the trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the

trust shall take action either to find a replacement for DTC to perform its functions at a comparable cost or, if such a replacement is unavailable, to issue and deliver printed certificates representing ownership of shares, unless the trust makes other arrangements with respect thereto satisfactory to NYSE Arca.

Creation Units

The Fund sells and redeems Shares in Creation Units on a continuous basis through the Distributor, without a sales load, at the NAV next determined after receipt of an order in proper form on any Business Day. As of the date of this SAI, the NYSE observes the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund will not issue fractional Creation Units. Shares of the Fund will only be issued against full payment, as further described in the prospectus and this SAI.

A Creation Unit is an aggregation of 50,000 Shares. The Board may declare a split or a consolidation in the number of Shares outstanding of the Fund or Trust, and make a corresponding change in the number of Shares in a Creation Unit.

To purchase or redeem any Creation Units from the Fund, you must be, or transact through, an Authorized Participant (“AP”). To be an AP, you must be either a broker-dealer or other participant (“Participating Party”) in the Continuous Net Settlement System (“Clearing Process”) of the National Securities Clearing Corporation (“NSCC”) or a participant in DTC with access to the DTC system (“DTC Participant”), and you must execute an agreement (“Participant Agreement”) with the Distributor that governs transactions in the Fund’s Creation Units.

Transactions by an AP that is a Participating Party using the NSCC system are referred to as transactions “through the Clearing Process.” Transactions by an AP that is a DTC Participant using the DTC system are referred to as transactions “outside the Clearing Process.”

Investors who are not APs but want to transact in Creation Units may contact the Distributor for the names of APs. An AP may require investors to enter into a separate agreement to transact through it for Creation Units and may require orders for purchases of shares placed with it to be in a particular form. Investors should be aware that their broker may not be an AP and, therefore, may need to place any order to purchase or redeem Creation Units through another broker or person that is an AP, which may result in additional charges. There are expected to be a limited number of APs at any one time.

Orders must be transmitted by an AP by telephone or other transmission method acceptable to the Distributor pursuant to procedures set forth in the Participant Agreement. Market disruptions and telephone or other communication failures may impede the transmission of orders.

Purchasing Creation Units

Fund Deposit

The consideration for a Creation Unit of the Fund is the Fund Deposit. The Fund Deposit will consist of the In-Kind Creation Basket and Cash Component, or an all cash payment (“Cash Value”), as determined by (PMC/Edge/PGI) to be permitted or required by the Fund. Short portions in the Fund’s portfolio [and any other financial instruments that] cannot be transferred in-kind, will be represented by cash in the Cash Component and not in the In-Kind Creation Basket.

The Cash Component will typically include a “Balancing Amount” reflecting the difference, if any, between the NAV of a Creation Unit and the market value of the securities in the In-Kind Creation Basket. If the NAV per Creation Unit exceeds the market value of the securities in the In-Kind Creation Basket, the purchaser pays the Balancing Amount to the Fund. By contrast, if the NAV per Creation Unit is less than the market value of the securities in the In-Kind Creation Basket, the Fund pays the Balancing Amount to the purchaser. The Balancing Amount ensures that the consideration paid by an investor for a Creation Unit is exactly equal to the value of the Creation Unit.

The Transfer Agent, in a portfolio composition file sent via the NSCC, generally makes available on each Business Day, immediately prior to the opening of business on the Exchange (currently 9:30 a.m., Eastern time), a list of the names and the required number of shares of each security in the In-Kind Creation Basket to be included in the current Fund Deposit for the Fund (based on information about the Fund’s portfolio at the end of the previous Business Day) (subject to correction). If applicable, [ ], through the NSCC, also makes available on each Business Day, the estimated Cash Component or Cash Value, effective through and including the previous Business Day, per Creation Unit.

The announced Fund Deposit is applicable, subject to any adjustments as described below, for purchases of Creation Units of the Fund until the next-announced Fund Deposit is made available. From day to day, the composition of the In-Kind Creation Basket may change as, among other things, corporate actions and investment decisions by the Sub-advisors are implemented for the Fund’s portfolio. All questions as to the composition of the In-

Kind Creation Basket and the validity, form, eligibility, and acceptance for deposit of any securities shall be determined by the Fund, and the Fund’s determination shall be final and binding. The Fund reserves the right to accept a nonconforming (i.e., custom) Fund Deposit. Payment of any stamp duty or the like shall be the sole responsibility of the AP purchasing a Creation Unit. The AP must ensure that all Deposit Securities properly denote change in beneficial ownership.

Cash in lieu

The Fund may, in its sole discretion, permit or require the substitution of an amount of cash (“cash in lieu”) to be added to the Cash Component to replace any security in the In-Kind Creation Basket. The Fund may permit or require cash in lieu when, for example, the securities in the In-Kind Creation Basket may not be available in sufficient quantity for delivery or may not be eligible for transfer through the systems of DTC or the Clearing Process. Similarly, the Fund may permit or require cash in lieu when, for example, the AP or its underlying investor is restricted under U.S. or local securities law or policies from transacting in one or more securities in the In-Kind Creation Basket. The Fund will comply with the federal securities laws in accepting securities in the In-Kind Creation Basket, including the securities in the In-Kind Creation Basket that are sold in transactions that would be exempt from registration under the 1933 Act.

In light of the foregoing, in order to seek to replicate the in-kind creation order process, the Fund expects to purchase the securities represented by the cash in lieu amount in the secondary market (“Market Purchases”). In such cases where the Fund makes Market Purchases because a security may not be permitted to be re-registered in the name of the Fund as a result of an in-kind creation order pursuant to local law or market convention, or for other reasons, the Authorized Participant will reimburse the Fund for, among other things, any difference between the market value at which the securities were purchased by the Fund and the cash in lieu amount (which amount, at Principal’s discretion, may be capped), applicable registration fees and taxes. Brokerage commissions incurred in connection with the Fund’s acquisition of securities will be at the expense of the applicable Fund and will affect the value of all Shares of the Fund, but Principal may adjust the transaction fee to the extent the composition of the securities changes or cash in lieu is added to the Cash Amount to protect ongoing shareholders.

Order Cut-Off Time

For an order involving a Creation Unit to be effectuated at the Fund’s NAV on a particular day, it must be received by the Distributor by or before the deadline for such order (“Order Cut-Off Time”). The Order Cut-Off Time for creation and redemption orders for the Fund is generally expected to be 4:00 p.m. Eastern time for In-Kind Creation and Redemption Baskets, and 3:00 p.m. Eastern time for Cash Value transactions. Accordingly, In-Kind Creation and Redemption Baskets are expected to be accepted until the close of regular trading on the Exchange on each Business Day, which is usually 4:00 p.m. Eastern time. On days when the Exchange or bond markets close earlier than normal (such as the day before a holiday), the Order Cut-Off Time is expected to track the Exchange or bond markets closing and be similarly earlier than normal.

Custom orders typically clear outside the Clearing Process and, therefore, like other orders outside the Clearing Process, may need to be transmitted early on the relevant Business Day to be effectuated at that day’s NAV. A custom order may be placed when, for example, an AP cannot transact in a security in the In-Kind Creation or Redemption Basket and additional cash is included in the Fund Deposit or Fund Redemption in lieu of such security. Custom orders may be required to be received by the Distributor by 3:00 p.m. Eastern time to be effectuated based on the Fund’s NAV on that Business Day.

In all cases, cash and securities should be transferred to the Fund by the “Settlement Date,” which is generally the Business Day immediately following the Transmittal Date for cash and the third Business Day following the Transmittal Date for securities. Persons placing custom orders or orders involving Cash Value should be aware of time deadlines imposed by intermediaries, such as DTC and/or the Federal Reserve Bank wire system, which may delay the delivery of cash and securities by the Settlement Date.

Placement of Creation Orders

All purchase orders must be placed by or through an AP. To order a Creation Unit, an AP must submit an irrevocable purchase order to the Distributor. In-kind (portions of) purchase orders will be processed through the Clearing Process when it is available. The Clearing Process is an enhanced clearing process that is available only for certain securities and only to DTC Participants that are also participants in the Clearing Process of the NSCC. In-kind (portions of) purchase orders not subject to the Clearing Process will go through a manual clearing process run by DTC. Fund Deposits that include government securities must be delivered through the Federal Reserve Bank wire transfer system (“Federal Reserve System”). Fund Deposits that include cash may be delivered through the Clearing Process or the Federal Reserve System. Certain orders for the Fund may be made

outside the Clearing Process. In-kind deposits of securities for such orders must be delivered through the Federal Reserve System (for government securities) or through DTC (for corporate securities).

Orders Using Clearing Process

In connection with creation orders made through the Clearing Process, the Distributor transmits, on behalf of the AP, such trade instructions as are necessary to effect the creation order. Pursuant to such trade instructions, the AP agrees to deliver the requisite Fund Deposit to the Trust, together with such additional information as may be required by the Distributor. An order to create Creation Units through the Clearing Process is deemed received by the Distributor on the Business Day the order is placed (“Transmittal Date”) if (i) such order is received by the Distributor by the Closing Time on such Transmittal Date and (ii) all other procedures set forth in the Participant Agreement are properly followed. Cash Components will be delivered using either the Clearing Process or the Federal Reserve System, as described below.

Orders Outside Clearing Process

Fund Deposits made outside the Clearing Process must state that the DTC Participant is not using the Clearing Process and that the creation of Creation Units will instead be effected through a transfer of securities and cash directly through DTC. With respect to such orders, the Fund Deposit transfer must be ordered by the DTC Participant on the Transmittal Date in a timely fashion so as to ensure the delivery of the requisite number of securities in the In- Kind Creation Basket (whether standard or custom) through DTC to the relevant Trust account by 11:00 a.m., Eastern time, (the “DTC Cut-Off Time”) on the Business Day immediately following the Transmittal Date. The amount of cash equal to the Cash Component, along with any cash in lieu and Transaction Fee, must be transferred directly to the Custodian through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by the Custodian no later than 12:00 p.m., Eastern time, on the Business Day immediately following the Transmittal Date. The delivery of corporate securities through DTC must occur by 3:00 p.m., Eastern time, on the Business Day immediately following the Transmittal Date. The delivery of government securities through the Federal Reserve System must occur by 3:00 p.m., Eastern time, on the Business Day immediately following the Transmittal Date.

An order to create Creation Units outside the Clearing Process is deemed received by the Distributor on the Transmittal Date if (i) such order is received by the Distributor by the Closing Time on such Transmittal Date and (ii) all other procedures set forth in the Participant Agreement are properly followed. If the Custodian does not receive both the required In-Kind Creation Basket by the DTC Cut-Off Time and the Cash Component by the appointed time, such order may be canceled. Upon written notice to the Distributor, a canceled order may be resubmitted the following Business Day using a Fund Deposit as newly constituted to reflect the then-current In-Kind Creation Basket and Cash Component. Except as provided in Appendix D, the delivery of Creation Units so created will occur no later than the third Business Day following the day on which the order is deemed received by the Distributor. APs that submit a canceled order will be liable to the Fund for any losses resulting therefrom. (See Appendix D for list of Foreign Market Holidays)

Orders involving foreign securities are expected to be settled outside the Clearing Process. Thus, upon receipt of an irrevocable purchase order, the Distributor will notify PGI and the Custodian of such order. The Custodian, who will have caused the appropriate local sub-custodian(s) of the Fund to maintain an account into which an AP may deliver the Fund Deposit (or cash in lieu), with adjustments determined by the Fund, will then provide information of the order to such local sub-custodian(s). The AP must also make available on or before the Settlement, by means satisfactory to the Fund, immediately available or same day funds in U.S. dollars estimated by the Fund to be sufficient to pay the Cash Component and Transaction Fee.

While, as stated above, Creation Units are generally delivered no later than the third Business Day following the day on which the order is deemed received by the Distributor. The Fund may settle Creation Unit transactions on a basis other than the one described above to accommodate foreign market holiday schedules, to account for different treatment among foreign and U.S. markets of dividend record dates and ex-dividend dates (that is the last day the holder of a security can sell the security and still receive dividends payable on the security), and in certain other circumstances.

Acceptance of Orders for Creation Units

The Trust reserves the absolute right to reject a creation order transmitted to it by the Distributor in respect of the Fund if: (i) the order is not in proper form; (ii) the investor(s), upon obtaining the Shares, would own 80% or more of the currently outstanding Shares of the Fund; (iii) the securities delivered do not conform to the In-Kind Creation Basket for the relevant date; (iv) acceptance of the Fund Deposit would have adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would otherwise, in the discretion of the Trust, the Fund, Principal or PGI, will have an adverse effect on the Trust, the Fund or the rights of beneficial owners; or (vii) in the event that circumstances that are outside the control of the Trust

make it practically impossible to process creation orders. Examples of such circumstances include acts of God; public service or utility problems resulting in telephone, telecopy and computer failures; fires, floods or extreme weather conditions; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the Trust, Principal, the Distributor, DTC, NSCC, the Custodian or sub-custodian or any other participant in the creation process; and similar extraordinary events. The Distributor shall notify an AP of its rejection of the order. The Fund, the Custodian, any sub- custodian and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits, and they shall not incur any liability for the failure to give any such notification.

Issuance of a Creation Unit

Once the Fund has accepted a creation order, upon next determination of a Fund’s NAV, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such NAV. The Distributor will transmit a confirmation of acceptance to the AP that placed the order.

Except as provided below, a Creation Unit will not be issued until the Fund obtains good title to the Kind-Creation Basket securities and the Cash Component, along with any cash in lieu and Transaction Fee. Except as provided in Appendix D, the delivery of Creation Units will generally occur no later than the third Business Day following the Transmittal Date for securities.

In certain cases, APs will create and redeem Creation Units on the same trade date. In these instances, the Trust reserves the right to settle these transactions on a net basis.

With respect to orders involving foreign securities, when the applicable local sub-custodian(s) has confirmed to the Custodian that the In-Kind Creation Basket (or cash in lieu) has been delivered to the Fund’s account at the applicable sub-custodian(s), the Distributor and PGI shall be notified of such delivery, and the Fund will issue and cause the delivery of the Creation Unit.

Creation Units may be created in advance of receipt by the Trust of all or a portion of the applicable In-Kind Creation Basket, provided the purchaser tenders an initial deposit consisting of any available securities in the In-Kind Creation Basket and cash equal to the sum of the Cash Component and at least 115% of the market value, as adjusted from time to time by, of the In-Kind Creation Basket securities not delivered (“Additional Cash Deposit”). Such initial deposit will have a value greater than the NAV of the Creation Unit on the date the order is placed. The order shall be deemed to be received on the Transmittal Date provided that it is placed in proper form prior to 4:00 p.m., Eastern time, on such date, and federal funds in the appropriate amount are deposited with the Custodian by the DTC Cut-Off Time the following Business Day. If the order is not placed in proper form by 4:00 p.m., Eastern time, or federal funds in the appropriate amount are not received by the DTC Cut-Off Time the next Business Day, then the order will be canceled or deemed unreceived and the AP effectuating such transaction will be liable to the Fund for any losses resulting therefrom.

To the extent securities in the In-Kind Creation Basket remain undelivered, pending delivery of such securities additional cash will be required to be deposited with the Trust as necessary to maintain an Additional Cash Deposit equal to at least 115% (as adjusted by PGI) of the daily marked-to-market value of the missing securities. To the extent that either such securities are still not received by 1:00 p.m., Eastern time, on the third Business Day following the day on which the purchase order is deemed received by the Distributor or a marked-to- market payment is not made within one Business Day following notification to the purchaser and/or AP that such a payment is required, the Trust may use the cash on deposit to purchase the missing securities, and the AP effectuating such transaction will be liable to the Fund for any costs incurred therein or losses resulting therefrom, including any Transaction Fee, any amount by which the actual purchase price of the missing securities exceeds the Additional Cash Deposit or the market value of such securities on the day the purchase order was deemed received by the Distributor, as well as brokerage and related transaction costs. The Trust will return any unused portion of the Additional Cash Deposit once all of the missing securities have been received by the Trust. The delivery of Creation Units so created will occur no later than the third Business Day following the day on which the purchase order is deemed received by the Distributor.

Transaction Fees

To compensate the Trust for costs incurred in connection with creation and redemption transactions, investors will be required to pay to the Trust a Transaction Fee as follows:

[To be added by amendment]

The Standard Transaction Fee applies to in-kind purchases of the Fund effected through the Clearing Process on any Business Day, regardless of the number of Creation Units purchased or redeemed that day (assuming, in the case of multiple orders on the same day, that the orders are received at or near the same time). A Transaction Fee of up to

four times the standard fee may apply to creation and redemption transactions that occur outside the Clearing Process. As shown in the table above, certain Fund Deposits consisting of a Cash Value will be subject to a variable charge of up to [ ]% in addition to the standard Transaction Fee. With cash received from the variable charge, PGI will purchase the necessary securities for the Fund’s portfolio and return any unused portion thereof to the investor.

Principal may adjust the Transaction Fee from time to time. The Standard Creation/Redemption Transaction Fee is based, in part, on the number of holdings in the Fund’s portfolio and may be adjusted on a quarterly basis if the number of holdings increases. Investors will also be responsible for the costs associated with transferring the securities in the In-Kind Creation (and Redemption) Baskets to (and from) the account of the Trust. Further, investors who, directly or indirectly, use the services of a broker or other intermediary to compose a Creation Unit in addition to an AP to effect a transaction in Creation Units may be charged an additional fee for such services.

Cash Purchase Method

When cash purchases of Creation Units are available or specified for the Fund, they will be effected in essentially the same manner as in-kind purchases. In the case of a cash purchase, the investor must pay the cash equivalent of the Fund Deposit. In addition, cash purchases may be subject to Transaction Fees.

Redeeming Creation Units

Fund Shares may be redeemed only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Fund through the Transfer Agent and only on a Business Day. The redemption proceeds for a Creation Unit will consist of the In-Kind Redemption Basket and a Cash Redemption Amount, or an all cash payment (“Cash Value”), in all instances equal to the value of a Creation Unit. Short positions and other instruments that cannot be transferred in kind will be represented by cash in the Cash Redemption Amount and not in the In-Kind Redemption Basket.

There can be no assurance that there will be sufficient liquidity in Shares in the secondary market to permit assembly of a Creation Unit. In addition, investors may incur brokerage and other costs in connection with assembling a Creation Unit.

The Cash Redemption Amount will typically include a Balancing Amount, reflecting the difference, if any, between the NAV of a Creation Unit and the market value of the securities in the In-Kind Redemption Basket. If the NAV per Creation Unit exceeds the market value of the securities in the In-Kind Redemption Basket, the Fund pays the Balancing Amount to the redeeming investor. By contrast, if the NAV per Creation Unit is less than the market value of the securities in the In-Kind Redemption Basket, the redeeming investor pays the Balancing Amount to the Fund.

The Transfer Agent, in a portfolio composition file sent via the NSCC, generally makes available on each Business Day, immediately prior to the opening of business on the Exchange (currently 9:30 a.m., Eastern time), a list of the names and the required number of shares of each security in the In-Kind Redemption Basket to be included in the current redemption proceeds for the Fund (based on information about the Fund’s portfolio at the end of the previous Business Day) (subject to correction). If applicable, [     ], through the NSCC, also makes available on each Business Day, the estimated Cash Component or Cash Value, effective through and including the previous Business Day, per Creation Unit. The Fund reserves the right to accept a nonconforming (i.e., custom) Fund Redemption.

In lieu of an In-Kind Redemption Basket and Cash Redemption Amount, Creation Units may be redeemed consisting solely of cash in an amount equal to the NAV of a Creation Unit, which amount is referred to as the Cash Value. Such redemptions for the Fund may be subject to a variable charge, as explained above. If applicable, information about the Cash Value will be made available by Transfer Agent.

From day to day, the composition of the In-Kind Redemption Basket may change as, among other things, corporate actions are implemented for the Fund’s portfolio. All questions as to the composition of the In-Kind Redemption Basket and the validity, form, eligibility, and acceptance for deposit of any securities shall be determined by the Fund, and the Fund’s determination shall be final and binding.

The right of redemption may be suspended or the date of payment postponed: (i) for any period during which the NYSE is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on the NYSE is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the Shares or determination of the Fund’s NAV is not reasonably practicable; or (iv) in such other circumstances as permitted by the SEC, including as described below.

Cash in lieu

The Fund may, in its sole discretion, permit or require the substitution of an amount of cash (“cash in lieu”) to be added to the Cash Redemption Amount to replace any security in the In-Kind Redemption Basket. The Fund may permit or require cash in lieu when, for example, the securities in the In-Kind Redemption Basket may not be available

in sufficient quantity for delivery or may not be eligible for transfer through the systems of DTC or the Clearing Process. Similarly, the Fund may permit or require cash in lieu when, for example, the AP or its underlying investor is restricted under U.S. or local securities law or policies from transacting in one or more securities in the In-Kind Redemption Basket or an underlying investor would be subject to unfavorable tax treatment if the investor received redemption proceeds consisting of certain non-U.S. securities. The Fund will comply with the federal securities laws in satisfying redemptions with the applicable In-Kind Redemption Basket, including the securities in the In-Kind Redemption Basket that are sold in transactions that would be exempt from registration under the 1933 Act. All redemption orders involving cash in lieu are considered to be “custom redemptions.”

Placement of Redemption Orders

Redemptions must be placed to the Transfer Agent through the Distributor. In addition, redemption orders must be processed either through the DTC process or the Clearing Process. To redeem a Creation Unit, an AP must submit an irrevocable redemption order to the Distributor.

An AP submitting a redemption order is deemed to represent to the Fund that it or, if applicable, the investor on whose behalf it is acting, (i) owns outright or has full legal authority and legal beneficial right to tender for redemption the Creation Unit to be redeemed and can receive the entire proceeds of the redemption, and (ii) all of the Shares in the Creation Unit to be redeemed have not been borrowed, loaned or pledged to another party nor are they the subject of a repurchase agreement, securities lending agreement or such other arrangement which would preclude the delivery of such Shares to the Fund. The Fund reserves the absolute right, in its sole discretion, to verify these representations, but will typically require verification in connection with higher levels of redemption activity and/or short interest in the Fund. If the AP, upon receipt of a verification report, does not provide sufficient verification of the requested representations, the redemption order will not be considered to be in proper form and may be rejected by the Fund.

In certain cases, APs will create and redeem Creation Units on the same trade date. In these instances, the Trust reserves the right to settle these transactions on a net basis.

Placement of Redemption Orders Using Clearing Process

Orders to redeem Creation Units through the Clearing Process are deemed received by the Trust on the Transmittal Date if (i) such order is received by the Transfer Agent not later than the Order Cut-Off Time on such Transmittal Date, and (ii) all other procedures set forth in the Participant Agreement are properly followed. Orders deemed received will be effectuated based on the NAV of the Fund as next determined. An order to redeem Creation Units using the Clearing Process made in proper form but received by the Trust after the Order Cut-Off Time will be deemed received on the next Business Day and will be effected at the NAV next determined on such next Business Day. In connection with such orders, the Distributor transmits on behalf of the AP such trade instructions as are necessary to effect the redemption. Pursuant to such trade instructions, the AP agrees to deliver the requisite Creation Unit(s) to the Fund, together with such additional information as may be required by the Distributor. Cash Redemption Amounts will be delivered using either the Clearing Process or the Federal Reserve System. The applicable In-Kind Redemption Basket and the Cash Redemption Amount will be transferred to the investor by the third NSCC business day following the date on which such request for redemption is deemed received.

Placement of Redemption Orders Outside Clearing Process     

Orders to redeem Creation Units outside the Clearing Process must state that the DTC Participant is not using the Clearing Process and that redemption of Creation Units will instead be effected through transfer of Shares directly through DTC. Such orders are deemed received by the Trust on the Transmittal Date if: (i) such order is received by the Transfer Agent not later than the Order Cut-Off Time on the Transmittal Date; (ii) such order is accompanied or followed by the delivery of both (a) the Creation Unit(s), which delivery must be made through DTC to the Custodian no later than the DTC Cut-Off Time on the Business Day immediately following the Transmittal Date and (b) the Cash Redemption Amount by 12:00 p.m., Eastern time, on the Business Day immediately following the Transmittal Date; and (iii) all other procedures set forth in the Participant Agreement are properly followed. After the Trust has deemed such an order received, the Trust will initiate procedures to transfer, and expect to deliver, the requisite In-Kind Redemption Basket and/or any Cash Redemption Amount owed to the redeeming party by the third Business Day following the Transmittal Date on which such redemption order is deemed received by the Trust.

Orders involving foreign securities are expected to be settled outside the Clearing Process. Thus, upon receipt of an irrevocable redemption order, the Distributor will notify PGI and the Custodian. The Custodian will then provide information of the redemption to the Fund’s local sub-custodian(s). The redeeming AP, or the investor on whose behalf it is acting, will have established appropriate arrangements with a broker-dealer, bank or other custody provider in each jurisdiction in which the securities are customarily traded and to which such securities (and any cash in lieu) can be delivered from the Fund’s accounts at the applicable local sub-custodian(s).

The calculation of the value of the In-Kind Redemption Basket and the Cash Redemption Amount to be delivered/received upon redemption will be made by the Custodian computed on the Business Day on which a redemption order is deemed received by the Trust. Therefore, if a redemption order in proper form is submitted to the Transfer Agent by a DTC Participant or an AP with the ability to transact through the Federal Reserve System, as applicable, not later than Closing Time on the Transmittal Date, and the requisite number of Shares of the relevant Fund are delivered to the Custodian prior to the DTC Cut-Off-Time, then the value of the In-Kind Redemption Basket and the Cash Redemption Amount to be delivered/received will be determined by the Custodian on such Transmittal Date. If, however, either: (i) the requisite number of Shares of the relevant Fund are not delivered by the DTC Cut- Off-Time, as described above, or (ii) the redemption order is not submitted in proper form, then the redemption order will not be deemed received as of the Transmittal Date. In such case, the value of the In-Kind Redemption Basket and the Cash Redemption Amount to be delivered/received will be computed on the Business Day following the Transmittal Date provided that the Fund Shares of the relevant Fund are delivered through DTC to the Custodian by 11:00 a.m., Eastern time, the following Business Day pursuant to a properly submitted redemption order.

If it is not possible to effect deliveries of the securities in the In-Kind Redemption Basket, the Trust may in its discretion exercise its option to redeem Shares in cash, and the redeeming beneficial owner will be required to receive its redemption proceeds in cash. In addition, an investor may request a redemption in cash that the Fund may, in its sole discretion, permit. In either case, the investor will receive a cash payment equal to the NAV of its Shares based on the NAV of Shares of the Fund next determined after the redemption request is received in proper form (minus a Transaction Fee, including a variable charge, if applicable, as described above).

Redemptions of Fund Shares for the In-Kind Redemption Basket will be subject to compliance with applicable federal and state securities laws and the Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Trust could not lawfully deliver specific securities in the In-Kind Redemption Basket upon redemptions or could not do so without first registering the securities in the In-Kind Redemption Basket under such laws. An AP or an investor for which it is acting subject to a legal restriction with respect to a particular security included in the In-Kind Redemption Basket applicable to the redemption of a Creation Unit may be paid an equivalent amount of cash. The AP may request the redeeming beneficial owner of the Shares to complete an order form or to enter into agreements with respect to such matters as compensating cash payment, beneficial ownership of shares or delivery instructions.

Delivery of Redemption Basket

Once the Fund has accepted a redemption order, upon next determination of the Fund’s NAV, the Fund will confirm the issuance of an In-Kind Redemption Basket, against receipt of the Creation Unit(s) at such NAV, any cash in lieu and Transaction Fee. A Creation Unit tendered for redemption and the payment of the Cash Redemption Amount, any cash in lieu and Transaction Fee will be effected through DTC. The AP, or the investor on whose behalf it is acting, will be recorded on the book-entry system of DTC.

In certain cases, APs will create and redeem Creation Units on the same trade date. In these instances, the Trust reserves the right to settle these transactions on a net basis.

Cash Redemption Method

When cash redemptions of Creation Units are available or specified for the Fund, they will be effected in essentially the same manner as in-kind redemptions. In the case of a cash redemption, the investor will receive the cash equivalent of the In-Kind Redemption Basket minus any Transaction Fees.

Settlement of Foreign Securities and Regular Foreign Holidays

The Fund generally intend to effect deliveries of Creation Units and portfolio securities on a basis of the Transmittal Date (“T”) plus three Business Days (i.e., days on which the national securities exchange is open) (“T+3”). The Fund may effect deliveries of Creation Units and portfolio securities on a basis other than T+3 to accommodate local holiday schedules, to account for different treatment among foreign and U.S. markets of dividend record dates and ex- dividend dates or under certain other circumstances. Given that foreign securities settle in accordance with the normal rules of settlement of such securities in the applicable foreign market, coupled with foreign market holiday schedules, the Settlement Date may be up to 14 calendar days after the Transmittal Date in certain circumstances.

The ability of the Trust to effect in-kind creations and redemptions within three Business Days of receipt of an order in good form is subject, among other things, to the condition that, within the time period from the date of the order to the date of delivery of the securities, there are no days that are holidays in the applicable foreign market. In such cases, the local market settlement procedures will not commence until the end of the local holiday periods. For every occurrence of one or more intervening holidays in the applicable foreign market that are not holidays observed in the U.S. equity market, the redemption settlement cycle will be extended by the number of such intervening holidays. In addition to holidays, other unforeseeable closings in a foreign market due to emergencies may also prevent the Trust

from delivering securities within normal settlement periods. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays or changes in local securities delivery practices could affect the information set forth herein at some time in the future.

Because the Fund’s portfolio securities may trade on days that the Fund’s Exchange is closed or on days that are not Business Days for the Fund, APs may not be able to redeem their Shares, or to purchase and sell Shares on the Exchange, on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.

The Trust will offer, issue and sell Shares of the Fund to investors only in Creation Units through the Distributor on a continuous basis at the NAV next determined after an order in proper form is received. The NAV of the Fund is expected to be determined as of 4:00 p.m. ET on each “Business Day,” which is defined to include any day that the Trust is open for business as required by Section 22(e) of the 1940 Act. The Trust will sell and redeem Creation Units of the Fund only on a Business Day. Applicants anticipate that a Creation Unit will consist of at least 25,000 Shares and that the price of a Share will range from $20 to $200.

The price of Shares trading on the Stock Exchange will be based on a current bid-offer market. No secondary sales will be made to Brokers at a concession by the Distributor or by the Fund. Purchases and sales of Shares on the Stock Exchange, which will not involve the Fund, will be subject to customary brokerage commissions and charges.

CALCULATION OF NAV

The Fund's NAV is calculated each day the New York Stock Exchange ("NYSE") is open, as of the close of business of the Exchange (normally 3:00 p.m. Central Time). The NAV of Fund shares is not determined on days the NYSE is closed (generally, New Year's Day; Martin Luther King, Jr. Day; Washington's Birthday/Presidents' Day; Good Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas). When an order to buy or sell shares is received, the share price used to fill the order is the next price calculated after the order is received in proper form.

The Fund’s NAV will be the value of a single Share. The NAV of Shares of the Fund will be computed by adding the value of the Fund’s investments, cash, and other assets, subtracting its liabilities, and dividing the result by the number of Shares outstanding.

According to the Registration Statement, the Fund’s Board of Trustees has delegated day-to-day valuation oversight responsibilities to PMC. PMC has established a Valuation Committee (“Valuation Committee”) to fulfill these oversight responsibilities.

Generally, the Fund will value its portfolio securities and assets as follows:

In computing the Fund’s NAV, the Fund’s fixed income securities (including defaulted debt and restricted securities (collectively, “OTC-Traded Securities”) will be valued based on price quotations obtained from a third-party pricing service or from a broker-dealer who makes markets in such securities. Any such third-party pricing service may use a variety of methodologies to value some or all such securities to determine the market price. For example, the prices of securities with characteristics similar to those held by the Fund may be used to assist with the pricing process. In addition, the pricing service may use proprietary pricing models. The Fund’s OTC-Traded Securities will generally be valued at bid prices.

Debt securities with remaining maturities of sixty days or less for which market quotations and information furnished by a third party pricing service are not readily available will be valued at amortized cost, which approximates current value.

Exchange traded equity securities, including ETFs, Depositary Receipts (including unsponsored ADRs), exchange-traded REITs, exchange-traded preferred stock, exchange-traded convertible bonds, and cleared swaps will be valued at market value, which will generally be determined using the last reported official closing or last trading price on the exchange or market on which the security is primarily traded at the time of valuation or, if no sale has occurred, at the last quoted bid price on the primary market or exchange on which they are traded.

Investment company securities (other than ETFs), including money market funds, closed end investment companies, unit investment trusts and open-end investment companies will be valued at NAV.

Exchange-traded futures contracts will be valued at the settlement or closing price determined by the applicable exchange.

Exchange-traded option contracts, including options on futures and swaps, will be valued at their most recent sale price. If no such sales are reported, these contracts will be valued at their most recent bid price.

OTC-traded derivative instruments, including options, swaps, will normally be valued on the basis of quotes obtained from a third party broker-dealer who makes markets in such securities or on the basis of quotes obtained from an independent third-party pricing service. The Fund’s OTC-traded derivative instruments will generally be valued at bid prices. Certain OTC-traded derivative instruments, such as interest rate swaps and credit default swaps, will be valued at the mean price.

Prices described above will be obtained from pricing services that have been approved by the Fund’s Board of Trustees. A number of independent third party pricing services are available and the Fund may use more than one of these services. The Fund may also discontinue the use of any pricing service at any time. PMC will engage in oversight activities with respect to the Fund’s pricing services, which includes, among other things, testing the prices provided by pricing services prior to calculation of the Fund’s NAV, conducting periodic due diligence meetings, and periodically reviewing the methodologies and inputs used by these services.

Foreign securities and instruments will be valued in their local currency following the methodologies described above. Typically, foreign securities, instruments and currencies will be translated to U.S. dollars, based on foreign currency exchange rate quotations supplied by a pricing service as of the close of the New York Stock Exchange (“NYSE”), which will use a proprietary model to determine the exchange rate.

Forward foreign currency exchange contracts will be valued at an interpolated rate based on days to maturity between the closest preceding and subsequent settlement period. Such interpolated rates are derived from foreign currency exchange rate quotations reported by an independent third-party pricing service.

Other portfolio securities and assets for which market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the opinion of the Valuation Committee, are deemed unreliable will be fair valued in good faith by the Valuation Committee in accordance with applicable fair value pricing policies. For example, if, in the opinion of the Valuation Committee, a security’s value has been materially affected by events occurring before the Fund’s pricing time but after the close of the exchange or market on which the security is principally traded, that security will be fair valued in good faith by the Valuation Committee in accordance with applicable fair value pricing policies.

In fair valuing a security, the Valuation Committee may consider factors including price movements in futures contracts and ADRs, market and trading trends, the bid/ask quotes of brokers, and off-exchange institutional trading.

TAX CONSIDERATIONS

Taxation of the Fund

It is a policy of the Fund to make distributions of substantially all of its respective investment income and any net realized capital gains. The Fund intends to qualify as regulated investment companies by satisfying certain requirements prescribed by Subchapter M of the Internal Revenue Code. If the Fund fails to qualify as a regulated investment company, it will be liable for taxes, significantly reducing its distributions to shareholders and eliminating shareholders' ability to treat distributions (as long or short-term capital gains or qualifying dividends) of the Fund in the manner they were received by the Fund.

Certain Funds may purchase securities of certain foreign corporations considered to be passive foreign investment companies by the Internal Revenue Service. To avoid taxes and interest that must be paid by the Fund if these instruments appreciate in value, the Fund may make various elections permitted by the tax laws. However, these elections could require that the Fund recognizes additional taxable income, which in turn must be distributed.

The Fund is required in certain cases to withhold and remit to the U.S. Treasury 28% of ordinary income dividends and capital gain dividends, and the proceeds of redemption of shares, paid to any shareholder 1) who has provided either an incorrect tax identification number or no number at all, 2) who is subject to backup withholding by the Internal Revenue Service for failure to report the receipt of interest or dividend income properly, or 3) who has failed to certify to the Fund that it is not subject to backup withholding or that it is a corporation or other "exempt recipient."

Taxation of Shareholders

A shareholder recognizes gain or loss on the sale or redemption of shares of the Fund in an amount equal to the difference between the proceeds of the sales or redemption and the shareholder's adjusted tax basis in the shares. All or a portion of any loss so recognized may be disallowed if the shareholder purchases other shares of the Fund within 30 days before or after the sale or redemption. In general, any gain or loss arising from (or treated as arising from) the

sale or redemption of shares of the Fund is considered capital gain or loss (long-term capital gain or loss if the shares were held for longer than one year). However, any capital loss arising from the sales or redemption of shares held for six months or less is disallowed to the extent of the amount of exempt-interest dividends received on such shares and (to the extent not disallowed) is treated as a long-term capital loss to the extent of the amount of capital gain dividends received on such shares. Capital losses in any year are deductible only to the extent of capital gains plus, in the case of a noncorporate taxpayer, $3,000 of ordinary income under current rules.

If a shareholder a) incurs a sales charge in acquiring shares of the Fund, b) disposes of such shares less than 91 days after they are acquired, and c) subsequently acquires shares of the Fund or another fund at a reduced sales charge pursuant to a right to reinvest at such reduced sales charge acquired in connection with the acquisition of the shares disposed of, then the sales charge on the shares disposed of (to the extent of the reduction in the sales charge on the shares subsequently acquired) shall not be taken into account in determining gain or loss on the shares disposed of but shall be treated as incurred on the acquisition of the shares subsequently acquired.

Shareholders should consult their own tax advisors as to the federal, state and local tax consequences of ownership of shares of the Fund in its particular circumstances.

Qualification as a Regulated Investment Company

The Fund intends to qualify annually to be treated as regulated investment companies (RICs) under the Internal Revenue Code of 1986, as amended, (the IRC). To qualify as RICs, the Fund must invest in assets which produce types of income specified in the IRC (Qualifying Income). Whether the income from derivatives, swaps, commodity-linked derivatives and other commodity/natural resource-related securities is Qualifying Income is unclear under current law. Accordingly, the Fund’s ability to invest in certain derivatives, swaps, commodity-linked derivatives and other commodity/natural resource-related securities may be restricted. Further, if the Fund does invest in these types of securities and the income is not determined to be Qualifying Income, it may cause the Fund to fail to qualify as a RIC under the IRC.

International Funds

Some foreign securities purchased by the Fund may be subject to foreign taxes that could reduce the yield on such securities. The amount of such foreign taxes is expected to be insignificant. The Fund may from year to year make an election to pass through such taxes to shareholders. If such election is not made, any foreign taxes paid or accrued will represent an expense to the Fund that will reduce its investment company taxable income.

Futures Contracts and Options

As previously discussed, some of the Fund invest in futures contracts or options thereon, index options, or options traded on qualified exchanges. For federal income tax purposes, capital gains and losses on futures contracts or options thereon, index options or options traded on qualified exchanges are generally treated as 60% long-term and 40% short-term. In addition, the Fund must recognize any unrealized gains and losses on such positions held at the end of the fiscal year. The Fund may elect out of such tax treatment, however, for a futures or options position that is part of an "identified mixed straddle" such as a put option purchased with respect to a portfolio security. Gains and losses on futures and options included in an identified mixed straddle are considered 100% short-term and unrealized gains or losses on such positions are not realized at year-end. The straddle provisions of the Code may require the deferral of realized losses to the extent that the Fund has unrealized gains in certain offsetting positions at the end of the fiscal year. The Code may also require recharacterization of all or a part of losses on certain offsetting positions from short-term to long-term, as well as adjustment of the holding periods of straddle positions.

PORTFOLIO HOLDINGS DISCLOSURE

The Fund’s portfolio holdings are publicly disseminated each day the Fund is open for business through financial reporting and news services, including publicly accessible Internet web-sites. In addition, for in-kind creations, a basket composition file, which includes the security names and share quantities to deliver in exchange for Shares, together with estimates and actual cash components, will be publicly disseminated daily prior to the opening of the Exchange via the National Securities Clearing Corporation ("NSCC"). The basket represents one Creation Unit of the Fund.

Access to information concerning the Fund’s portfolio holdings may be permitted at other times to personnel of third party service providers, including the Fund’s custodian, transfer agent, auditors and counsel, as may be necessary to conduct business in the ordinary course in a manner consistent with such service providers’ agreements with the Trust on behalf of the Fund.

In addition to the permitted disclosures described above, shareholders can also obtain the Fund’s Statement of Additional Information (“SAI”), the Fund’s Shareholder Reports, and its Form N-CSR and Form N-SAR, filed twice a

year. The Fund’s SAI and Shareholder Reports are available free upon request from the Fund, and those documents and the Form N-CSR and Form N-SAR may be viewed on-screen or downloaded from the SEC’s web site at www.sec.gov.

PROXY VOTING POLICIES AND PROCEDURES

The Board of Trustees has delegated responsibility for decisions regarding proxy voting for securities held by the Fund to Principal or to the Fund's Sub-Advisor, as appropriate. Principal and each Sub-Advisor will vote such proxies in accordance with its proxy policies and procedures, which have been reviewed by the Board of Trustees, and which are found in Appendix C. Any material changes to the proxy policies and procedures will be submitted to the Board of Trustees for approval.

Information regarding how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended ___________, will be available, without charge, upon request, by calling 1-800-[ ] or on the SEC website at http://www.sec.gov.

The By-laws of the Fund sets the quorum requirement (a quorum must be present at a meeting of shareholders for business to be transacted). The By-laws of the Fund states that a quorum is "The presence in person or by proxy of one-third of the shares of the Fund outstanding at the close of business on the Record Date constitutes a quorum for a meeting of that Fund."

Certain proposals presented to shareholders for approval require the vote of a "majority of the outstanding voting securities," which is a term defined in the 1940 Act to mean, with respect to the Fund, the affirmative vote of the lesser of 1) 67% or more of the voting securities of the Fund present at the meeting of that Fund, if the holders of more than 50% of the outstanding voting securities of the Fund are present in person or by proxy, or 2) more than 50% of the outstanding voting securities of the Fund (a "Majority of the Outstanding Voting Securities").

Principal Holders of Securities

The Fund is unaware of any persons who own beneficially (but are not shareholders of record) more than 5% of the Fund's outstanding shares. The following list identifies the shareholders of record who own 5% or more of the Fund's outstanding shares as of ________________.

Management Ownership

As of ___________, the Officers and Trustees of the Trust as a group owned less than 1% of the outstanding shares of the Fund.

Sub-Advisor: Edge Asset Management, Inc.

Compensation

Edge Asset Management offers a competitive compensation structure that is evaluated annually relative to other asset management firms to ensure its continued competitiveness and alignment with industry best practices. The objective of the structure is to offer market competitive compensation that aligns individual and team contributions with client performance objectives in a manner that is consistent with industry standards and business results.

Compensation for all team members is comprised of base salary and variable incentive components. As team members advance in their careers, the variable component increases in its proportion commensurate with responsibility levels. The variable component for investment professionals is designed to reinforce investment performance, firm performance, team collaboration, regulatory compliance, client retention and client satisfaction. Fund performance is measured against relative client benchmarks and peer groups over one year, three-year and five-year periods, calculated quarterly, reinforcing a longer term orientation.

Payments under the variable incentive plan are delivered in the form of cash or a combination of cash and deferred compensation. The amount of incentive delivered in the form of deferred compensation depends on the size of an individual’s incentive award as it relates to a tiered deferral scale. Deferred compensation is required to be invested into funds managed by the team, via a co-investment program; thus, aligning the interests of investment professionals with client objectives. Co-investment is subject to a three year cliff vesting schedule which meets our objective of increased employee retention.

In addition to base salary and variable incentive, portfolio managers and senior professionals participate in the Principal Financial Group Long-term Incentive Plan (“Plan”). Awards from this Plan are based on individual performance and are delivered in the form of three-year cliff vest Principal Financial Group (“PFG”) RSUs or a combination of three-year cliff vest PFG RSUs and three-year ratable vest PFG stock options; therefore, aligning the interests of team members with PFG stakeholders.
