Principal Investment Strategies

The Fund seeks to achieve its investment objective by allocating its assets among the following general investment categories: inflation-indexed bonds, securities of real estate companies, commodity index-linked notes, fixed-income securities, securities of natural resource companies, master limited partnerships (MLPs), publicly-listed infrastructure companies, and floating rate debt. The Fund actively trades portfolio securities.

The Fund concentrates its investments (invests more than 25% of its net assets) in securities in the real estate and energy/natural resources industries.

In managing the Fund, Principal Management Corporation ("Principal"), the Fund’s investment advisor, determines the Fund's strategic asset allocation among the general investment categories described below, which are executed by multiple sub-advisors. The allocations will vary from time to time, and the Fund may add additional investment categories. Except for its policy to concentrate in the real estate and energy/natural resources industries, the Fund retains considerable latitude in allocating its assets.

A portion of the Fund's assets is invested primarily in inflation-indexed bonds issued by the U.S. and non-U.S. governments, their agencies or instrumentalities and U.S. and non-U.S. corporations. Inflation-indexed bonds are fixed-income securities that are structured to provide protection against inflation. The value of the bond's principal or the interest income paid on the bond is adjusted to track changes in an official inflation measure.

A portion of the Fund's assets is invested in a combination of commodity index-linked notes and fixed-income securities. Commodities are assets that have tangible properties, such as oil, coal, natural gas, agricultural products, industrial metals, livestock and precious metals. In order to gain exposure to the commodities markets without investing directly in physical commodities, the Fund invests in commodity index-linked notes. Commodity index-linked notes are derivative debt instruments with principal and/or coupon payments linked to the performance of commodity indices. These notes are sometimes referred to as "structured notes" because the terms of these notes may be structured by the issuer and the purchaser of the note. The value of these notes will rise or fall in response to changes in the underlying commodity index and will be subject to credit and interest rate risks that typically affect debt securities. The fixed income securities are primarily short-term U.S. Treasury and Agency notes and bonds.

A portion of the Fund's assets is invested in the real estate industry. The Fund invests in equity securities of global companies principally engaged in the real estate industry ("real estate companies"). A real estate company has at least 50% of its assets, income or profits derived from products or services related to the real estate industry. Real estate companies include real estate investment trusts ("REITs"), REIT-like entities, and companies with substantial real estate holdings such as paper, lumber, hotel and entertainment companies as well as building supply manufacturers, mortgage lenders, and mortgage servicing companies.

A portion of the Fund's assets is invested in securities of companies that primarily own, explore, mine, process or otherwise develop natural resources, or supply goods and services to such companies. Natural resources generally include precious metals, such as gold, silver and platinum, ferrous and nonferrous metals, such as iron, aluminum and copper, strategic metals such as uranium and titanium, hydrocarbons such as coal, oil and natural gas, timberland, undeveloped real property and agricultural commodities.

A portion of the Fund's assets is invested in MLPs. Generally, MLPs are engaged in the transportation, storage, processing, refining, marketing, production, or mining of natural resources. The Fund invests primarily in the mid-stream category of MLPs, which is generally comprised of pipelines used to gather, process, transport, and distribute natural gas, crude oil, and refined petroleum products.

A portion of the Fund’s assets is invested in domestic and foreign publicly-listed infrastructure companies. Publicly-listed infrastructure equity securities trade on an exchange and include, but are not limited to, companies involved in the ownership and/or operations of infrastructure assets within the transportation, communications, water, electricity transmission and distribution, and oil and gas storage, processing and transportation industries.

A portion of the Fund’s assets is invested in below-investment-grade (sometimes called “junk”) or comparable unrated floating rate debt (also known as bank loans, syndicated loans, leveraged loans or senior floating rate interests). Floating rate debt has a variable coupon that resets periodically, with interest payments determined by a representative interest rate index (e.g. LIBOR or the federal funds rate) plus a fixed spread. As a result, the coupon payments vary, or “float” with prevailing market interest rates.

Principal Investment Strategies

Principal Management Corporation ("Principal"), the Fund's investment adviser, allocates the Fund's assets among one or more of the investment strategies described below, which are executed by one or more of the Fund's sub-advisors. In making these allocations, Principal seeks to combine the strategies of the sub-advisors efficiently and systematically so that the Fund generates, through a diversified set of investment strategies, a positive total return with relatively low volatility and low sensitivity or correlation to market indices. By allocating the Fund’s assets among a variety of investment strategies, which will vary from time-to-time, the Fund seeks to lessen risk and reduce volatility. Principal may also direct a sub-advisor to reduce or omit its investment in certain assets or asset classes in an effort to achieve its desired combination of the Fund's strategies.

In pursuing its strategies, the Fund invests in a broad range of instruments including, but not limited to, equities, bonds, currencies, convertible securities and derivatives such as futures, options, swaps (including, for example, credit default, interest rate, and currency swaps) and forwards. The Fund intends to engage in derivative transactions to gain exposure to a variety of securities or attempt to reduce risk. The Fund intends to invest in securities that are tied economically to a number of countries throughout the world, including the U.S.; however, the Fund has no requirements as to the amount of its net assets that it invests in foreign securities. The Fund is considered non-diversified, which means it can invest a higher percentage of assets in securities of individual issuers than a diversified fund. The Fund actively trades securities.

Some of the strategies take long and/or short positions. When taking a short position, the Fund may sell an instrument that it does not own and then borrow to meet its settlement obligations. The Fund may take short positions in futures, forwards or swaps. A short position will benefit from a decrease in price of the underlying instrument and will lose value if the price of the underlying instrument increases. Long positions will profit if the value of the instrument increases. Simultaneously engaging in long investing and short selling reduces the net exposure of the overall portfolio to general market movements. Relative value positions may be taken as well in the various strategies. Relative value strategies capitalize on price differences between similar securities or relative value among securities of the same company.

The Fund may use all or some of the following strategies to varying degrees, depending on market conditions, and may add additional strategies. Principal may allocate 0 to 100% of the Fund’s assets to any of these strategies at any time.

Credit Long/Short and Distressed Credit. This strategy utilizes a flexible investment approach that allocates investments across a global range of investment opportunities related to credit, currencies and interest rates, while employing risk management strategies. This strategy invests in fixed income securities and instruments and may invest in both investment-grade securities and below investment grade bonds (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). This strategy may also invest in the following securities: securities denominated in foreign currencies and in U.S. dollar denominated securities of foreign issuers, preferred securities, convertible securities, Rule 144A securities, mortgage or asset-backed securities, floating rate debt (including bank loans), distressed investments, emerging markets, equities and derivative instruments, such as options, futures contracts, forwards or swap agreements. This strategy may utilize derivative instruments in an effort to minimize volatility. Also, at times, this strategy expects to gain its investment exposure substantially through the use of derivatives. The notional value of this strategy’s long and short investment exposures may at times each reach 100% of the assets invested in this strategy (excluding instruments used primarily for duration, yield curve, and interest rate management and short-term investments), although these exposures may be higher or lower at any given time. This strategy may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The strategy may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls).

Equity Long/Short. This strategy provides long and short exposure to a diversified portfolio of equities which involves simultaneously investing in equities (i.e., investing long) the sub-advisor expects to increase in value (securities the sub-advisor believes are undervalued) and either selling equities (i.e., short sales or short selling) the sub-advisor expects to decrease in value (securities the sub-advisor believes are overvalued) or hedging equity market exposure in another way (i.e., by using derivatives such as futures or options). Long/short equity expresses industry views by emphasizing certain industries and it also seeks to exploit pricing inefficiencies between related equity securities. An example of exploiting pricing inefficiencies between related equity securities is building a portfolio containing long positions in the strongest companies of several industries and taking short positions in companies showing signs of weakness in the corresponding industries. This strategy has available two methods of analysis: fundamental analysis, a method of security analysis that involves examining a company's financial statements and operations, especially sales, earnings, products, management and competition and quantitative analysis, a method of security analysis that involves use of mathematical models to examine a company's measurable characteristics such as revenue, earnings, margins and market share.

Equity Market Neutral. This strategy seeks to profit by exploiting pricing inefficiencies between related equity securities and neutralizing exposure to market risk by maintaining long and short positions. Equity market neutral is not expected to have industry overweights.

Dedicated Short Bias. The dedicated short bias strategy seeks to profit by shorting stocks that have negative market sentiment and neutralizing exposure to market risk by maintaining long and short positions.

Global Macro. Global macro strategies seek to profit from movement in the prices of securities that are highly sensitive to macroeconomic conditions, across a broad spectrum of assets. This strategy provides long and short exposure to developed country equities, currencies, and bonds markets.

Emerging Markets. This strategy seeks to profit from investing in equities, bonds, and currencies of issuers in emerging markets. This strategy provides long and short exposure to emerging country equity, debt, and currency markets, and long and short exposure to a basket of liquid equity securities traded on emerging and developed market exchanges.

Convertible Arbitrage. Convertible arbitrage strategies seek to profit from the complexity of the pricing of convertible bonds (which contain elements of both a fixed income security and an equity option) by structuring trades using multiple securities within the capital structure of a convertible bond issuer. The Fund may purchase the convertible bond of a given issuer and simultaneously sell short the common stock of that same issuer to take advantage of a mispricing of either security. This strategy takes positions in various global convertible debt and preferred securities and an offsetting position in various global equities directly linked to the convertible securities. In implementing this strategy, the Fund may use derivatives to hedge against a decline in interest rates or credit exposure.

Currency Instruments, Futures Contracts, Futures-Related Instruments and Equity Swaps. These strategies seek to profit from the design and implementation of quantitative selection models to help predict upcoming movements in any combination of fixed income, currency, or equity markets. This strategy provides long and short exposure to developed country equities, bonds and currency markets and long and short exposure to emerging country equity and currency markets.

Event Driven. Event driven strategies seek to profit from investing in the securities of companies based not on a value or growth investment style but rather on the basis that a specific event or catalyst will affect future prices. This strategy attempts to capitalize on price discrepancies and returns generated by corporate activity, such as merger arbitrage. In merger arbitrage, the Fund will employ a diversified, disciplined strategy to attempt to capture the returns from holding a long/short portfolio of stocks of companies involved in mergers.

Fixed Income Arbitrage. Fixed income arbitrage seeks to profit from exploiting mispricing of various, liquid fixed income or interest rate sensitive securities. This strategy provides long and short exposure to developed country bond and currency markets, long and short exposure to investment grade credit markets and long and short exposure to forward mortgage-backed securities trading in the to be announced (“TBA”) market.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal obligations (securities issued by or on behalf of state or local governments and other public authorities). Many of these are from California. Municipal obligations pay interest that is exempt from federal income tax. The Fund has a flexible investment strategy and invests in obligations of any duration and credit quality, including below investment grade bonds (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).

The Fund invests in other debt obligations, including (but not limited to) taxable municipal obligations, U.S. Treasury securities, obligations of the U.S. Government, its agencies and instrumentalities (“Agency Securities”) and inverse floating rate obligations, which are generally more volatile than other types of municipal obligations. The Fund invests in exchange-traded funds (ETFs) to gain exposure to the municipal market.

The Fund purchases derivative instruments, which derive their value from another instrument, security or index. The Fund purchases or sells various kinds of financial futures contracts to hedge against changes in interest rates or as a substitute for the purchase of portfolio securities. The Fund also enters into interest rate swaps and credit derivatives, which includes credit default swaps.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in preferred securities at the time of purchase. Preferred securities generally pay fixed rate dividends (though some are adjustable rate) and typically have "preference" over common stock in the payment of dividends and the liquidation of a company's assets, but are junior to all forms of the company's debt. Most of the securities purchased by the Fund are preferred securities of companies rated at the time of purchase BBB- or higher by Standard & Poor's Rating Service ("S&P") or Baa3 or higher by Moody's Investor Service, Inc. ("Moody's") or, if unrated, of comparable quality in the opinion of the Sub-Advisor. The Fund also invests up to 15% of its assets in high yield, below investment grade bonds (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).

The Fund concentrates its investments (invests more than 25% of its net assets) in securities in the U.S. and non-U.S financial services (i.e., banking, insurance and commercial finance,) industry. The Fund also regularly invests in the real estate investment trust (i.e. REIT) and utility industries.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in dividend-paying equity securities of companies with small to medium market capitalizations (those with market capitalizations ranging from between $200 million and $7 billion) at the time of purchase. The Fund invests in value equity securities, an investment strategy that emphasizes buying equity securities that appear to be undervalued. The Fund invests in the securities of foreign issuers, real estate investment trusts, preferred securities, convertible securities, fixed-income securities, master limited partnerships, and royalty trusts.

ADDITIONAL INFORMATION ABOUT INVESTMENT STRATEGIES AND RISKS

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

With the exception of the Opportunistic Municipal Fund, the Board of Directors may change each 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 a Fund's investment objective or investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that each Fund will meet its objective.

The investment strategies identified in this section provide specific information about each 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.

Each Fund is designed to be a portion of an investor's portfolio. No Fund is intended to be a complete investment program. Investors should consider the risks of a 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 each Fund.

The following table lists each Fund and identifies whether the strategies and risks discussed in this section (listed in alphabetical order) are principal, non-principal, or not applicable to each Fund. A Fund is subject to Risk of Being an Underlying Fund to the extent that a fund of funds invests in the Fund. The Statement of Additional Information ("SAI") contains additional information about investment strategies and their related risks.

Arbitrage

A fund employing arbitrage strategies has the risk that anticipated opportunities do not play out as planned, resulting in potentially reduced returns or losses to the fund as it unwinds failed trades. For example, with respect to the convertible arbitrage strategy, an issuer may default or may be unable to make interest and dividend payments when due; with respect to the merger arbitrage strategy, the merger deal may terminate prior to closing, thereby imposing losses to the fund.

Asset-Backed Securities and Mortgage-Backed Securities

Asset-backed securities (“ABS”) are fixed income instruments secured by and payable from assets such as installment sales or loan contract (such as auto, home equity, or student loans) receivables, leases, credit card receivables, and other receivables. Mortgage-backed securities (“MBS”) represent interests in underlying pools of mortgages. Some can be commercial mortgage-backed securities, which are secured by commercial or multi-family properties (“CMBS”). Certain asset-backed securities present a heightened level of risk because, in the event of default, the liquidation value of the underlying assets may be inadequate to pay any unpaid principal or interest. The value of mortgage-backed and asset-backed securities may be affected by changes in credit quality or value of the mortgage loans or other assets that support the securities. In addition, for mortgage-backed securities, when market conditions result in an increase in the default rates on the underlying mortgages and the foreclosure values of the underlying real estate are below the outstanding amount of the underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be doubtful. To the extent that the mortgages underlying mortgage-backed securities or asset-backed securities are sub-prime mortgages (mortgages granted to borrowers whose credit histories would not support conventional mortgages), the risk of default is higher. These defaults have caused unexpected losses for loan originators and certain sub-prime lenders. The structure of some of these securities may be complex and there may be less available information than for other types of debt securities. If interest rates fall and the loans underlying these securities are prepaid faster than expected, the fund may have to reinvest the prepaid principal in lower yielding securities, thus reducing the fund’s income. Conversely, if interest rates increase and the loans underlying the securities are prepaid more slowly than expected, the expected duration of the securities may be extended. This reduces the potential for the fund to invest the principal in higher yielding securities.

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 primarily are 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 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. 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 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.

Commodity Index-Linked Notes

Commodities are assets that have tangible properties, such as oil, coal, natural gas, agricultural products, industrial metals, livestock and precious metals. The value of commodities may be affected by overall market movements and other factors affecting the value of a particular industry or commodity, such as weather, disease, embargoes, or political and regulatory developments. Funds may seek exposure to commodity markets through investments in commodity index-linked notes, which are derivative debt instruments issued by U.S. and foreign banks, brokerage firms, insurance companies and other corporations with principal and/or coupon payments linked to the performance of commodity indices. These notes expose the fund to movements in commodity prices. They are also subject to credit, counterparty, and interest rate risk. Commodity index-linked notes are often leveraged, increasing the volatility of each note's market value relative to changes in the underlying commodity index. At the maturity of the note, the fund may receive more or less principal than it originally invested. The fund may also receive interest payments on the note that are less than the stated coupon interest payments.

Commodity-Related Investments

The value of commodities investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include weather, embargoes, tariffs, and health, political, international and regulatory developments. Economic and other events (whether real or perceived) can reduce the demand for commodities, which may reduce market prices and cause the value of fund shares to fall. The frequency and magnitude of such changes cannot be predicted. Exposure to commodities and commodities markets may subject a fund to greater volatility than investments in traditional securities. No active trading market may exist for certain commodities investments, which may impair the ability of a fund to sell or to realize the full value of such investments in the event of the need to liquidate such investments. In addition, adverse market conditions may impair the liquidity of actively traded commodities investments. Certain types of commodities instruments (such as commodity swaps) are subject to the risk that the counterparty to the instrument will not perform or will be unable to perform in accordance with the terms of the instrument.

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 could also include corporate bonds, notes or preferred stocks of U.S. or foreign issuers. The option allows 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.

The fund treats convertible securities as both fixed-income and equity securities for purposes of investment policies and limitations because of their unique characteristics. Funds that invest in convertible securities may invest in convertible securities that are below investment grade. Many convertible securities are relatively illiquid.

Derivatives

A 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 exposure 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. A 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. A 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. A 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). A fund may enter into forward commitment agreements (not as a principal investment strategy), which call for the fund to purchase or sell a security on a future date at a fixed price. A 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 a fund's Sub-Advisor hedges 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 a 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, and an insufficient liquid secondary market for particular options.

Equity Securities

Equity securities include common stocks, convertible securities, 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 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. A 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 securities, 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.

Foreign Securities

Principal defines foreign securities as those issued by:

Depending on the fund, the fund may invest in securities of developed markets, developing (also called "emerging") markets, or both. 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 United States, Canada, Japan, Australia, New Zealand, and most nations located in Western Europe.

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 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 fund investors. To protect against future uncertainties in foreign currency exchange rates, the funds are 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 a 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 a 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.

A 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.

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. A 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.

Hedging

The success of a fund’s hedging strategy will be subject to the Sub-Adviser’s 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 a fund’s hedging strategy will also be subject to the Sub-Adviser’s ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Sub-Adviser may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent a fund from achieving the intended hedge or expose a 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

Debt securities rated at the time of purchase BB+ or lower by Standard & Poor's Ratings Services or Ba1 or lower by Moody's or, if not rated, determined to be of equivalent quality by Principal or the Sub-Advisor 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 a 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, a 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 a 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 a fund, the fund may retain the security if Principal or Sub-Advisor thinks it is in the best interest of shareholders.

Industry Concentration

A fund that concentrates its investments (invests more than 25% of its net assets) in a particular industry (or group of industries) is more exposed to the overall condition of the particular industry than a fund that invests in a wider variety of industries. A particular industry could be affected by economic, business, supply-and-demand, political, or regulatory factors. Companies within the same industry could react similarly to such factors. As a result, a fund’s concentration in a particular industry would increase the possibility that the fund’s performance will be affected by such factors.

Initial Public Offerings ("IPOs")

An IPO is a company's first offering of stock to the public. IPO risk is that the market value of IPO shares will fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. In addition, the market for IPO shares can be speculative and/or inactive for extended periods of time. The limited number of shares available for trading in some IPOs may make it more difficult for a fund to buy or sell significant amounts of shares without an unfavorable impact on prevailing prices. Investors in IPO shares can be affected by substantial dilution in the value of their shares by sales of additional shares and by concentration of control in existing management and principal shareholders.

When a fund's asset base is small, a significant portion of the fund's performance could be attributable to investments in IPOs because such investments would have a magnified impact on the fund. As the fund's assets grow, the effect of the fund's investments in IPOs on the fund's performance probably will decline, which could reduce the fund's performance. Because of the price volatility of IPO shares, a fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the fund's portfolio and lead to increased expenses to the fund, such as commissions and transaction costs. By selling IPO shares, the fund may realize taxable gains it will subsequently distribute to 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 these funds 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 these funds. These funds generally invest in inverse floating rate investments that include embedded leverage, thus exposing these funds 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. A 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.

Leverage

If a 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 a 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 a 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 a 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 a fund is not able to close out a leveraged position because of market illiquidity, a 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

A 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.

Market Volatility and Issuer Risk

The value of a 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 a 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, as a result of a change in current law or a change in an MLP's business, an MLP were 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 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. You should also be aware that the "total return" line in the Financial Highlights section reflects portfolio turnover costs.

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. In certain circumstances, an issuer of preferred securities may 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 share many investment characteristics with bonds; therefore, the risks and potential rewards of investing in a fund that invests in preferred securities are more similar to those associated with a bond fund than a stock fund.

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 a 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 and mining, lumber and 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 a 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.

Royalty Trusts

A royalty trust generally acquires an interest in natural resource or chemical companies and distributes the income it receives to its investors. A sustained decline in demand for natural resource and related products could adversely affect royalty trust revenues and cash flows. Such a decline could result from a recession or other adverse economic conditions, an increase in the market price of the underlying commodity, higher taxes or other regulatory actions that increase costs, or a shift in consumer demand. Rising interest rates could harm the performance and limit the capital appreciation of royalty trusts because of the increased availability of alternative investments at more competitive yields. Fund shareholders will indirectly bear their proportionate share of the royalty trusts' expenses.

Short Sales

A fund enters into a short sale by selling a security it has borrowed (typically from a broker or other institution). If the market price of a security increases after a fund borrows the security, the fund will suffer a (potentially unlimited) loss when it replaces the borrowed security at the higher price. In certain cases, purchasing a security to cover a short position can itself cause the price of the security to rise further, thereby exacerbating the loss. In addition, a fund may not always be able to borrow the security at a particular time or at an acceptable price. Before a fund replaces a borrowed security, it is required to designate on its books cash or liquid assets as collateral to cover the fund’s short position, marking the collateral to market daily. This obligation limits a fund’s investment flexibility, as well as its ability to meet redemption requests or other current obligations. The fund may also take a short position in a derivative instrument, such as a future, forward or swap. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying instrument. Short sales also involve transaction and other costs that will reduce potential fund gains and increase potential fund losses.

Small and Medium Market Capitalization Companies

Funds 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, funds 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 a 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 a fund may take temporary defensive measures. In taking such measures, a fund may fail to achieve its investment objective.

Underlying Funds

An underlying fund to a fund of funds may experience relatively large redemptions or purchases as the fund of funds periodically reallocates or rebalances its assets. These transactions may accelerate the realization of taxable income if sales of portfolio securities result in gains and could increase transaction costs. In addition, when a fund of funds reallocates or redeems significant assets away from an underlying fund, the loss of assets to the underlying fund could result in increased expense ratios for that fund.
