Principal Investment Strategies of the Fund

The Fund invests in both equity and debt securities of domestic and foreign issuers in different capitalization ranges and in developed or developing countries. Under normal market conditions, the Fund invests at least 65% of its total assets in equity and debt securities that are expected to generate income. Additionally, under normal market conditions, the Fund invests at least 25% of its assets in fixed income securities and at least 25% of its assets in equity securities. The percentages of equity and debt securities the Fund holds may vary from time to time. There is no limit on the Fund’s investments in foreign securities.

Equity Securities. In selecting equity securities, the portfolio managers use fundamental research to select securities for the Fund’s portfolio. While the process may change over time or vary in particular cases, in general the selection process currently employs a fundamental approach in analyzing issuers on factors such as a company’s financial performance, competitive strength and prospects, industry position, and business model and management strength. Industry outlook, market trends and general economic conditions may also be considered. The portfolio managers aim to maintain a broad diversification across all major economic sectors. The Fund’s equity portfolio is constructed and regularly monitored based upon several analytical tools, including quantitative investment models. Quantitative models are used as part of the idea generation process to rank equity securities within each sector to identify potential buy and sell candidates for further fundamental analysis.

Debt Securities. The portfolio managers look for high current yields and typically search for corporate and government debt securities that offer: attractive relative value, more income than U.S. treasury obligations, a balance of risk and return, high income potential and portfolio diversification.

The Fund can invest up to 25% of its total assets below investment grade securities, also referred to as “junk bonds,” but cannot invest more than 10% of its assets in below investment grade non-convertible securities. These restrictions are applied at the time of purchase and the Fund may continue to hold a security whose credit rating has been downgraded or, in the case of an unrated security, after the Fund’s investment adviser, Invesco has changed its assessment of the security’s credit quality. As a result, credit rating downgrades or other market fluctuations may cause the Fund’s holdings of below-investment-grade securities to exceed, at times significantly, this restriction for an extended period of time. Investment-grade securities are rated within one of the four highest rating categories of a nationally recognized statistical rating organization such as S&P Global Ratings (AAA, AA, A or BBB) (or in the case of unrated securities, determined by the Adviser to be comparable to securities rated investment-grade).

The Fund may also invest in unrated securities, in which case the Adviser internally assigns ratings to those securities, after assessing their credit quality and other factors, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Adviser’s credit analysis process is consistent or comparable with the credit analysis process used by a nationally recognized statistical ratings organization.

Derivative Securities. The Fund may also use derivative instruments to seek income or to try to manage investment risks, including: options, futures, swaps, “structured” notes, mortgage-related securities and equity-linked debt securities.

The Fund may sell securities that no longer meet the above criteria.

The Fund’s holdings may at times differ significantly from the weightings of the indices comprising its reference index (the Reference Index). The Fund’s Reference Index is a customized weighted index currently comprised of the following underlying broad-based security indices: 65% of the Bloomberg Barclays U.S. Aggregate Bond Index and 35% of the Russell 3000 Index. The Fund is not managed to be invested in the same percentages as those indices comprising the Reference Index.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risks of Other Equity Securities. Most convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Because the Fund can invest up to 25% of its total assets in below-investment-grade securities, the Fund’s credit risks are greater than those of funds that buy only investment-grade securities. This restriction is applied at the time of purchase and the Fund may continue to hold a security whose credit rating has been downgraded or, in the case of an unrated security, after the Adviser has changed its assessment of the security’s credit quality. As a result, credit rating downgrades or other market fluctuations may cause the Fund’s holdings of below-investment-grade securities to exceed, at times significantly, this restriction for an extended period of time. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. If the Fund has more than 25% of its total assets invested in below-investment-grade securities, the Adviser will not purchase additional below-investment-grade securities until the level of holdings in those securities no longer exceeds the restriction.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks. Mortgage-backed securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities. In addition, a substantial portion of the Fund’s assets may be subject to “forward roll” transactions (also referred to as “mortgage dollar rolls”) at any given time, which subject the Fund to the risk that market value of the mortgage-related securities involved might decline, and that the counterparty might default in its obligations.

Asset-Backed Securities Risk. The Fund can buy asset-backed securities, which are fractional interests in pools of loans and are collateralized by the loans, other assets or receivables. They are typically issued by trusts and special purpose corporations that pass the income from the underlying pool to the purchasers. These securities are subject to the risk of default by the issuer as well as by the borrowers of the underlying loans in the pool, and to interest rate and prepayment risks.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines. They may have more limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Small- and mid-cap companies may have unseasoned management or less depth in management skill than larger, more established companies. They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all.

Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives are required to be executed on a regulated market and/or cleared through a clearinghouse. Entering into a derivative transaction with a clearinghouse may entail further risks and costs.

Risks of Quantitative Models. The portfolio managers use quantitative models as part of the idea generation process. Quantitative models are based upon many factors that measure individual securities relative to each other. Such models, which can be adversely affected by errors or imperfections in the factors or the data on which measurements are based, any technical issues with construction or implementation of the model, or a failure to perform as expected, may not identify securities that perform well in the future.

Principal Investment Strategies of the Fund

The Fund mainly invests in common stocks of U.S. companies that the portfolio managers expect to have above-average growth rates. The Fund seeks to invest in newer companies or in more established companies that are in the early growth phase of their business cycle, which is typically marked by above-average growth rates. Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of “mid-cap” issuers, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund defines mid-cap issuers as those issuers that are within the range of market capitalizations of the Russell Midcap^® Growth Index. This range is subject to change at any time due to market activity or changes in the composition of that index. The range of the Russell Midcap Growth Index is reconstituted annually to preserve its capitalization characteristics. The Fund may invest up to 20% of its net assets in companies in other market capitalization ranges. The Fund measures a company’s capitalization at the time the Fund buys a security, and is not required to sell a security if the issuer’s capitalization moves outside of the Fund’s definition of mid-cap issuers.

The Fund invests primarily in U.S. companies but may also purchase securities of issuers in any country, including developed countries and emerging markets. The Fund has no limits on the amount of its assets that can be invested in foreign securities.

In selecting investments for the Fund, the portfolio managers look for companies with high growth potential using a “bottom-up” stock selection process. The “bottom-up” approach focuses on fundamental analysis of individual issuers before considering the impact of overall economic, market or industry trends. This approach includes analysis of a company’s financial statements and management structure and consideration of the company’s operations, product development, and its industry position.

The portfolio managers currently focus on high-growth companies that are characterized by industry leadership, market share growth, high caliber management teams, sustainable competitive advantages, and strong growth themes or new innovative products or services. The portfolio managers monitor individual issuers for changes in the factors above, which may trigger a decision to sell a security, but does not require a decision to do so. The factors considered by the portfolio managers may vary in particular cases and may change over time.

Principal Investment Strategies of the Fund

The Fund seeks to achieve its investment objective by investing in alternative (or non-traditional) asset classes and investment strategies, including but not limited to the following:

Fundamental and quantitatively driven alpha strategies, such as global macro (investment across broad asset and/or sector classes), equity long/short, currency and volatility arbitrage strategies
Real assets, such as commodities, gold and other precious metals and minerals, real estate and master limited partnerships (MLPs)
Income alternatives, such as event-linked securities and loans

The Fund may invest in some or all of the asset classes and strategies listed above, but under normal market conditions will not invest more than 50% of its total assets in any single asset class. The Fund’s investment adviser, Invesco will monitor the markets and allocate assets among asset classes and strategies based on changing market or economic conditions or investment opportunities. The Fund may change its emphasis on an asset class or strategy based on the Adviser’s and the Fund’s sub-adviser’s evaluation of those market and economic factors and investment opportunities. In determining how much of the Fund’s assets to invest in a particular asset class or strategy, the Adviser looks for opportunities across various asset classes and strategies and attempts to allocate the Fund’s assets in a manner that seeks to generally diversify the portfolio across those asset classes and strategies. In pursuing its investment objective, the Fund has the flexibility to utilize a variety of investment strategies and techniques to select investments, and the list of asset classes and strategies shown above that the Fund may invest in is not exhaustive. In response to changing market or economic conditions or investment opportunities, the Adviser may change any or all of the Fund’s asset classes and strategies, including changing to asset classes and strategies not listed above, or may change the Fund’s asset allocations, including making no allocation at all to an asset class or strategy. The Adviser may make such changes at any time without prior approval from or notice to shareholders.

Under normal market conditions, the Fund will invest a substantial portion of its assets in a number of different countries throughout the world, including the United States. The Fund is managed to be “benchmark agnostic” in an attempt to provide positive absolute returns while limiting volatility; however, when compared to its current index (the ICE Bank of America Merrill Lynch 3-month U.S. Treasury Bill Index) the Fund will normally experience higher volatility than the index.

The Fund may invest in all types of equity securities, including common stock, preferred stock, convertible securities, rights and warrants, and other securities or instruments whose prices are linked to the value of common stock. The Fund may also invest in debt securities of any kind and of varying duration and maturities, including but not limited to, securities that pay a fixed or fluctuating rate of interest, securities convertible into equity securities, securities issued or guaranteed by the U.S. federal and state governments or by their agencies and instrumentalities, securities issued or guaranteed by foreign governments, international agencies or supra-national entities, securities issued or guaranteed by domestic or foreign private issuers, event-linked securities (including “catastrophe” bonds and other insurance-linked securities), senior loans, asset- and mortgage-backed securities, and debt securities whose returns are linked to the performance of a particular market benchmark or strategy (such as exchange-traded notes). The Fund can invest without limit in investment-grade and below investment-grade, high-yield debt securities (commonly referred to as “junk bonds”). “Investment-grade” debt securities are rated in one of the top four rating categories by a nationally recognized statistical rating organization such as Moody’s Investors Service or S&P Global Ratings. The Fund may also invest in unrated securities, in which case the Adviser may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Adviser’s credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization.

There is no maximum or minimum amount for investments in either equity or fixed-income securities, except as otherwise indicated in this prospectus or the Fund’s statement of additional information. There are generally no restrictions on where the Fund may invest geographically or on the amount of the Fund’s assets that can be invested in either U.S. or foreign securities, including real estate securities and securities of issuers in developing and emerging markets. The Fund does not limit its investments to issuers in a particular market capitalization range and at times may invest a substantial portion of its assets in one or more particular market capitalization ranges. The Fund’s investment in MLPs is limited to no more than 25% of its total assets.

The Fund can take long positions in investments that are believed to be undervalued and short positions in investments that are believed to be overvalued or which are established for hedging purposes, including long and short positions in equities and equity-sensitive convertibles, fixed income securities, and derivatives or other types of securities. The Fund’s overall long or short positioning can vary based on market and economic conditions, and the Fund may take both long and short positions simultaneously. The Fund can seek to take advantage of arbitrage opportunities in equity and fixed income, commodity, and currency prices and market volatility.

The Fund may invest in the securities of other investment companies, subject to any limits imposed by the Investment Company Act of 1940 Act, as amended, including other entities sponsored and/or advised by the Adviser or an affiliate. The Fund may use derivatives to seek income or capital gain, to hedge against the risks of other investments, or as a substitute for direct investment in a particular asset class. Structured notes, options, futures, forward contracts, and swaps are some of the types of derivatives the Fund can use.

In times of adverse or unstable market or economic conditions, such as reduced market liquidity or increased volatility, the Fund may hold a portion of its assets in cash, money market securities or other similar, liquid investments, including in shares of money market mutual funds in the Oppenheimer family of funds. This may also include shares of funds that provide exposure to inflation-protected debt securities and short-term investment-grade debt securities. This will generally occur at times when there is an inability to immediately invest funds received from purchases of Fund shares or from redemptions of other investments or to maintain liquidity.

The Fund may invest up to 25% of its total assets in a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the Subsidiary). The Subsidiary invests primarily in commodity-linked derivatives (including commodity futures, financial futures, options and swap contracts) and exchange-traded funds and other exchange-traded products related to gold or other special minerals (Gold ETFs). The Subsidiary may also invest in certain fixed-income securities and other investments that may serve as margin or collateral for its derivatives positions. Investments in the Subsidiary are intended to provide the Fund with exposure to commodities market returns within the limitations of the federal tax requirements that apply to the Fund. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. The Fund’s investment in the Subsidiary may vary based on the portfolio managers’ use of different types of commodity-linked derivatives, fixed-income securities, Gold ETFs, and other investments. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include the Fund’s indirect investments through the Subsidiary.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Asset Allocation Risk. Because the Fund typically invests in a combination of securities, the Fund’s ability to achieve its investment objective depends largely upon selecting the best mix of investments. There is the risk that the portfolio manager’s evaluations and assumptions regarding market conditions may be incorrect. During periods of rapidly rising stock prices, the Fund might not achieve growth in its share prices to the same degree as funds focusing only on stocks. The Fund’s investments in stocks may make it more difficult to preserve principal during periods of stock market volatility. The Fund’s use of a particular investment style might not be successful when that style is out of favor and the Fund’s performance may be adversely affected by the asset allocation decisions.

Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risks of Alternative Investment Strategies. The Fund utilizes alternative investment strategies, which are strategies that the portfolio managers expect to result in investment performance that does not correlate with the performance of traditional asset classes, such as equity and fixed-income investments. The Fund also seeks to utilize a diverse mix of alternative investment strategies, in the hope that individual strategies yield low performance correlation to other alternative investment strategies used by the Fund. However, alternative investments may be more volatile or illiquid, particularly during periods of market instability, and the Fund cannot guarantee that diverse alternative investment strategies will yield uncorrelated performance under all market conditions. In addition, the particular mix of alternative investments in the Fund’s portfolio may not be sufficiently diversified. The Fund is subject to the risk that its alternative investments may undergo a correlation shift, resulting in returns that are correlated with the broader market and/or with the Fund’s other alternative investments.

Liquidity Risks. Securities that are difficult to value or to sell promptly at an acceptable price are generally referred to as “illiquid” securities. If it is required to sell securities quickly or at a particular time (including sales to meet redemption requests) the Fund could realize a loss on illiquid investments.

Risks of Other Equity Securities. Most convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines. They may have more limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Small- and mid-cap companies may have unseasoned management or less depth in management skill than larger, more established companies. They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all.

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Risks of Event-Linked Securities. Event-linked securities (including “catastrophe” bonds and other insurance-linked securities) are fixed income securities for which the return of principal and payment of interest is contingent on the non-occurrence of a trigger event, such as a hurricane, earthquake, or other catastrophe or series of catastrophe events that leads to physical or economic loss(es). If the trigger event occurs prior to maturity, the Fund may lose all or a portion of its principal and additional interest. Event-linked securities may expose the Fund to certain other risks, including issuer default, adverse regulatory or jurisdictional interpretations, liquidity risk and adverse tax consequences.

Risks of Inflation-Protected Debt Securities. Inflation-indexed bonds, including Treasury Inflation-Protected Securities (TIPS), are fixed income securities whose principal value is periodically adjusted according to an identified rate of inflation. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds with similar maturities. If inflation declines, the principal amount or the interest rate of an inflation-indexed bond will be adjusted downward. This will result in reduced income and may result in a decline in the bond’s price which could cause losses for the Fund. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal or interest rate is adjusted for inflation. Inflation-indexed bonds normally will decline in price when real interest rates rise which could cause losses for the fund.

Risks of Exchange-Traded Notes (ETNs). ETNs are senior, unsecured, unsubordinated debt securities traded on an exchange (e.g., the NYSE) whose returns are linked to the performance of a particular market index or strategy, minus applicable fees. ETNs are subject to credit risk, and the value of an ETN may drop due to a downgrade in the issuer’s credit rating. An ETN may lose all or a portion of its value if the issuer fails. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in applicable interest rates, and economic, legal, political or geographic events that affect the underlying assets on which the index is based. The Fund may invest substantially in ETNs that are subject to the risks associated with industry or sector concentration. When the Fund invests in an ETN it will bear its proportionate share of the fees and expenses borne by the ETN, which will reduce the return realized at maturity or upon redemption. The Fund’s decision to sell ETN holdings may be limited by the availability of a secondary market and it may not be able to liquidate ETN holdings at the desired time or price.

The Fund may invest in ETNs for which an affiliate of the Adviser provides certain index selection and marketing services. As a result, an affiliate of the Adviser may be paid service fees that are indirectly incurred by the Fund and its shareholders (in addition to Fund expenses). The Adviser will voluntarily waive a portion of its management fee to the extent that the Fund’s share of service fees paid to affiliates of the Adviser are attributable to investment in such an ETN.

Risks of Commodity-Linked Investments. Commodity-linked investments are considered speculative and have substantial risks, including the risk of loss of a significant portion of their principal value. Prices of commodities and commodity-linked investments may fluctuate significantly over short periods due to a variety of factors, including for example agricultural, economic and regulatory developments. These risks may make commodity-linked investments more volatile than other types of investments. The tax treatment of commodity-linked investments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level.

Risks of Mining & Metal Industry Securities. Investments in mining and metal industry companies may be speculative and may be subject to greater price volatility than investments in other types of companies. The special risks of mining and metal industry investments include:

changes in international monetary policies or economic and political conditions can affect the supply of gold and precious metals and consequently the value of mining and metal company investments;

the United States or foreign governments may pass laws or regulations limiting metal investments for strategic or other policy reasons;

the principal supplies of gold are concentrated in only five countries or territories: Australia, Canada, Russia and certain other former Soviet Union countries, South Africa and the United States, the governments of which may pass laws or regulations limiting metal investments for strategic or other policy reasons; and

increased environmental or labor costs may depress the value of mining and metal investments.

Risks of Investing in Gold ETFs. An exchange-traded fund or exchange-traded product that invests in gold bullion (Gold ETF) is a publicly-traded investment entity that acquires and physically holds gold bullion, the shares of which are intended to reflect the price performance of gold bullion. A Gold ETF will sell gold from time to time to pay expenses, which will reduce the amount of gold represented by each ETF share. Investment in a Gold ETF is subject to the same risks of investing directly in gold bullion, including tax risk. The market value of Gold ETF shares may differ from their net asset value because the supply and demand of Gold ETF shares may be different from the supply and demand for the underlying asset. The Fund will indirectly bear its proportionate share of the management fees associated with Gold ETFs. It is possible that a Gold ETF in which the Fund invests may have to liquidate its holdings at a time when the price of gold is falling.

Risks of Investing in Real Estate Markets. The performance of the Fund’s investments in real estate securities is closely linked to the performance of the real estate markets. Property values or revenues from real estate investments may fall due to many different factors, including market disruptions, declining rents, negative economic developments that affect businesses and individuals, increased operating costs, low market demand or oversupply, obsolescence, competition, uninsured casualty losses, condemnation losses, environmental liabilities, the failure of borrowers to repay loans in a timely manner, changes in prevailing interest rates or rates of inflation, lack of available credit or changes in federal or state taxation policies that affect real estate. The price of a real estate company’s securities may also drop due to dividend reductions, lowered credit ratings, poor management, or other factors that generally affect companies. Real estate companies, including REITs and real estate operating companies (REOCs), tend to be small- and mid-cap companies and their shares may be more volatile and less liquid. An industry downturn could adversely impact the Fund’s performance.

Smaller Real Estate Company Risks. Smaller companies are typically subject to greater risk of loss than larger companies. They may be more sensitive to changes in a company’s earnings expectations and may experience more price volatility. Smaller companies’ securities often trade in lower volumes and may be harder to sell at an acceptable price. Buy and sell transactions in a smaller company’s stock could impact the stock’s price more than it would a larger company’s stock. Smaller real estate companies may have limited access to financial and other resources and lack liquidity in a declining market. They may have unseasoned management and may be more sensitive to changes in management or depth of management skill than larger, more established companies.

Risks of Investing in REITs. Investment in REITs is closely linked to the performance of the real estate markets. Property values or revenues from real estate investments may fall due to a number of factors, including but not limited to disruptions in real estate markets, increased vacancies or declining rents, increased property taxes and other operating costs, low demand or oversupply, the failure of borrowers to repay loans in a timely manner, changes in tax and regulatory requirements and changes in interest rates or rates of inflation. Mortgage REITs are particularly subject to interest rate risks.

REITs are dependent upon the quality of their management and may not be diversified geographically or by property type. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. REITs generally tend to be small- to mid-cap stocks and are subject to risks of investing in those securities, including limited financial resources and dependency on heavy cash flow. REITs must satisfy certain requirements in order to qualify for favorable tax treatment under applicable tax laws, and a failure to qualify could adversely affect the value of the REIT. By investing in REITs through the Fund, a shareholder will bear expenses of the REITs in addition to expenses of the Fund.

Risks of Foreign Real Estate Investments. Because real estate trends are cyclically unique to different countries and world regions, an up or down real estate market in the U.S. may not coincide with the trend in another country. Fluctuations in the relation of a foreign currency to the U.S. dollar could adversely impact cash flow and profits of real estate companies, which in turn could negatively impact the Fund’s performance and ability to pay dividends. Securities of foreign real estate companies may have less trading volume, may lack the level of transparency generally present in U.S. companies, and may be more sensitive to volatility. In emerging markets in particular, real estate ownership laws, land rights and tax laws are subject to rapid and unexpected changes as a result of regulatory and political changes. Foreign real estate investments in those countries are more susceptible to the imposition of adverse or confiscatory taxes on foreign properties, currency transfer restrictions, expropriation and difficulty in enforcing obligations.

Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives are required to be executed on a regulated market and/or cleared through a clearinghouse. Entering into a derivative transaction with a clearinghouse may entail further risks and costs.

Risks of Hedging. The Fund may engage in “hedging” strategies, including short sales, futures and other derivatives in an effort to protect assets from losses due to declines in the value of the Fund’s portfolio. There are risks in the use of these investment and trading strategies. There can be no assurance that the hedging strategies used will be successful in avoiding losses, and hedged positions may perform less favorably in generally rising markets than unhedged positions. If the Fund uses a hedging strategy at the wrong time or judges market conditions incorrectly, the strategy could reduce the Fund’s return. In some cases, derivatives or other investments may be unavailable, or the investment adviser may choose not to use them under market conditions when their use, in hindsight, may be determined to have been beneficial to the Fund. No assurance can be given that the investment adviser will employ hedging strategies with respect to all or any portion of the Fund’s assets.

Risks of Leverage. Certain derivatives and other investments of the Fund may involve leverage. Leverage may be created when an investment exposes the Fund to a risk of loss that exceeds the amount invested. Certain derivatives and other investments provide the potential for investment gain or loss that may be several times greater than the change in the value of an underlying security, asset, interest rate, index or currency, resulting in the potential for a loss that may be substantially greater than the amount invested.

Some derivatives and other leveraged investments have the potential for unlimited loss, regardless of the size of the initial investment. Because leverage can magnify the effects of changes in the value of the Fund and make the Fund’s share price more volatile, a shareholder’s investment in the Fund will tend to be more volatile, resulting in larger gains or losses in response to the fluctuating prices of the Fund’s investments.

Risks of Master Limited Partnerships. Investments in securities of master limited partnerships (MLPs) are subject to all the risks of investments in common stock, in addition to risks related to the following: a common unit holder’s limited control and limited rights to vote on matters affecting the MLP; potential conflicts of interest between the MLP and the MLP’s general partner; cash flow; dilution; and the general partner’s right to require unit holders to sell their common units at an undesirable time or price. MLP common unit holders may not elect the general partner or its directors and have limited ability to remove an MLP’s general partner. MLPs may issue additional common units without unit holder approval, which could dilute the ownership interests of investors holding MLP common units. MLP common units, like other equity securities, can be affected by macro-economic and other factors affecting the stock market in general, expectations of interest rates, investor sentiment towards an issuer or certain market sector, changes in a particular issuer’s financial condition, or unfavorable or unanticipated poor performance of a particular issuer. Prices of common units of individual MLPs, like prices of other equity securities, also can be affected by fundamentals unique to the partnership or company, including earnings power and coverage ratios. A holder of MLP common units typically would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances, creditors of an MLP would have the right to seek return of capital distributed to a limited partner, which would continue after an investor sold its investment in the MLP. The value of an MLP security may decline for reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s products or services. Due to the heavy state and federal regulations that an MLP’s assets may be subject to, an MLP’s profitability could be adversely impacted by changes in the regulatory environment.

Generally, the securities markets may move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors. The market value of a security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. A security’s market value also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

MLP Tax Risk. MLPs are generally treated as partnerships for U.S. federal income tax purposes. MLPs generally do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses regardless of whether it receives a cash distribution from the MLP. A change in current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which could result in the MLP being required to pay federal income tax (as well as state and local income taxes) on its taxable income. This could have the effect of reducing the amount of cash available for distribution by the MLP, resulting in a reduction of the value of the Fund’s investment in the MLP and lower income to the Fund. Changes in the laws, regulations or related interpretations relating to the Fund’s investments in MLPs could increase the Fund’s expenses, reduce its cash distributions, negatively impact the value of an investment in an MLP, or otherwise impact the Fund’s ability to implement its investment strategy.

MLP Debt Securities Risks. MLP debt securities, including bonds and debentures, have characteristics similar to the fixed income securities of other issuers.

Risks of Energy Infrastructure and Energy-Related Assets or Activities. Energy infrastructure MLPs are subject to risks specific to the energy and energy-related industries, including, but not limited to: fluctuations in commodity prices may impact the volume of energy commodities transported, processed, stored or distributed; reduced volumes of natural gas or other energy commodities available for transporting, processing, storing or distributing may affect the profitability of an MLP; slowdowns in new construction and acquisitions can limit growth potential; reduced demand for oil, natural gas and petroleum products, particularly for a sustained period of time, could adversely affect MLP revenues and cash flows; depletion of natural gas reserves or other commodities, if not replaced, could impact an MLP’s ability to make distributions; changes in the regulatory environment could adversely affect the profitability of MLPs; extreme weather and environmental hazards could impact the value of MLP securities; rising interest rates could result in higher costs of capital and drive investors into other investment opportunities; and threats of attack by terrorists on energy assets could impact the market for MLPs.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Risks of Long/Short Holdings. Under certain conditions, even if the value of the Fund’s long positions are rising, this could be offset by declining values of the Fund’s short positions. Conversely, it is possible that rising values of the Fund’s short positions could be offset by declining values of the Fund’s long positions. In either scenario the Fund may experience losses. In a market where the value of both the Fund’s long and short positions are declining, the Fund may experience substantial losses.

Risks of Short Sales. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases between the date of the short sale and the date on which the Fund closes the short position. A short sale of a security creates the risk of an unlimited loss, since the price of the security sold short could theoretically increase without limit.

Purchasing securities previously sold short to close out a short position can itself cause the price of the securities to rise further, thereby increasing the loss. Further, there is no assurance that a security the Fund needs to buy to cover a short position will be available for purchase at a reasonable price. Short sales may cause a higher portfolio turnover rate and increase the Fund’s brokerage and other transaction expenses. Short selling is considered a speculative investment practice.

Risks of Arbitrage. Arbitrage risk is the risk that securities purchased pursuant to a strategy intended to take advantage of a perceived relationship between the value of two or more securities may not perform as expected.

Risks of Senior Loans and Other Loans. The Fund may invest in loans, and in particular, in floating rate loans (sometimes referred to as “adjustable rate loans”) that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as “Senior Loans.” Loans may be collateralized or uncollateralized. They typically pay interest at rates that are reset periodically based on a reference benchmark that reflects current interest rates, plus a margin or premium. In addition to the risks typically associated with debt securities, such as credit and interest rate risk, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders’ security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans are expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interests rates do and therefore should more closely track market movements in interest rates.

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund’s ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences.

To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund’s ability to pay redemption proceeds in a timely manner may be adversely affected, as well as the Fund’s performance.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity’s credit risk), in addition to the exposure the Fund has to the creditworthiness of the borrower.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities.

Risks of Investments in Other Investment Companies. As an investor in another investment company, the Fund would be subject to the risks of that investment company’s portfolio. Investing in another investment company may also involve paying a premium above the value of that investment company’s portfolio securities and is subject to a ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the payment of any premiums, expenses or sales charges. The Investment Company Act of 1940 also imposes limitations on mutual funds’ investments in other investment companies.

The Fund may also invest in exchange-traded funds (ETFs), which are subject to all the risks of investing in investment companies as described above. Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, shares of ETFs potentially may trade at a discount or a premium to their net asset value. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

Risks of Money Market Instruments. The Fund may invest in money market instruments. Money market instruments are short-term, US dollar-denominated debt instruments issued or guaranteed by domestic and foreign corporations and financial institutions, the U.S. government, its agencies and instrumentalities and other entities. Money market instruments include certificates of deposit, commercial paper, repurchase agreements, treasury bills, certain asset-backed securities and other short term debt obligations that have a final maturity, as defined under rules under the Investment Company Act of 1940, of 397 days or less. They may have fixed, variable or floating interest rates. Money market instruments are subject to certain risks, including the risk that an issuer of an obligation that the Fund holds might have its credit rating downgraded or might default on its obligations, or that interest rates might rise sharply, causing the value of the Fund’s investments to fall.

Risks of Investments In The Fund’s Wholly-Owned Subsidiary. The Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to its investor protections (except as otherwise noted in this prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Subsidiary is wholly-owned and controlled by the Fund and managed by the Adviser. Therefore, the Fund’s ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders. In addition, changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information and could adversely affect the Fund. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the performance of the Fund and/or the Subsidiary. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.

Principal Risks of Investing in the Fund

rr_RiskNarrativeTextBlock

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Asset Allocation Risk. Because the Fund typically invests in a combination of securities, the Fund’s ability to achieve its investment objective depends largely upon selecting the best mix of investments. There is the risk that the portfolio manager’s evaluations and assumptions regarding market conditions may be incorrect. During periods of rapidly rising stock prices, the Fund might not achieve growth in its share prices to the same degree as funds focusing only on stocks. The Fund’s investments in stocks may make it more difficult to preserve principal during periods of stock market volatility. The Fund’s use of a particular investment style might not be successful when that style is out of favor and the Fund’s performance may be adversely affected by the asset allocation decisions.

Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risks of Alternative Investment Strategies. The Fund utilizes alternative investment strategies, which are strategies that the portfolio managers expect to result in investment performance that does not correlate with the performance of traditional asset classes, such as equity and fixed-income investments. The Fund also seeks to utilize a diverse mix of alternative investment strategies, in the hope that individual strategies yield low performance correlation to other alternative investment strategies used by the Fund. However, alternative investments may be more volatile or illiquid, particularly during periods of market instability, and the Fund cannot guarantee that diverse alternative investment strategies will yield uncorrelated performance under all market conditions. In addition, the particular mix of alternative investments in the Fund’s portfolio may not be sufficiently diversified. The Fund is subject to the risk that its alternative investments may undergo a correlation shift, resulting in returns that are correlated with the broader market and/or with the Fund’s other alternative investments.

Liquidity Risks. Securities that are difficult to value or to sell promptly at an acceptable price are generally referred to as “illiquid” securities. If it is required to sell securities quickly or at a particular time (including sales to meet redemption requests) the Fund could realize a loss on illiquid investments.

Risks of Other Equity Securities. Most convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines. They may have more limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Small- and mid-cap companies may have unseasoned management or less depth in management skill than larger, more established companies. They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all.

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Risks of Event-Linked Securities. Event-linked securities (including “catastrophe” bonds and other insurance-linked securities) are fixed income securities for which the return of principal and payment of interest is contingent on the non-occurrence of a trigger event, such as a hurricane, earthquake, or other catastrophe or series of catastrophe events that leads to physical or economic loss(es). If the trigger event occurs prior to maturity, the Fund may lose all or a portion of its principal and additional interest. Event-linked securities may expose the Fund to certain other risks, including issuer default, adverse regulatory or jurisdictional interpretations, liquidity risk and adverse tax consequences.

Risks of Inflation-Protected Debt Securities. Inflation-indexed bonds, including Treasury Inflation-Protected Securities (TIPS), are fixed income securities whose principal value is periodically adjusted according to an identified rate of inflation. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds with similar maturities. If inflation declines, the principal amount or the interest rate of an inflation-indexed bond will be adjusted downward. This will result in reduced income and may result in a decline in the bond’s price which could cause losses for the Fund. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal or interest rate is adjusted for inflation. Inflation-indexed bonds normally will decline in price when real interest rates rise which could cause losses for the fund.

Risks of Exchange-Traded Notes (ETNs). ETNs are senior, unsecured, unsubordinated debt securities traded on an exchange (e.g., the NYSE) whose returns are linked to the performance of a particular market index or strategy, minus applicable fees. ETNs are subject to credit risk, and the value of an ETN may drop due to a downgrade in the issuer’s credit rating. An ETN may lose all or a portion of its value if the issuer fails. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in applicable interest rates, and economic, legal, political or geographic events that affect the underlying assets on which the index is based. The Fund may invest substantially in ETNs that are subject to the risks associated with industry or sector concentration. When the Fund invests in an ETN it will bear its proportionate share of the fees and expenses borne by the ETN, which will reduce the return realized at maturity or upon redemption. The Fund’s decision to sell ETN holdings may be limited by the availability of a secondary market and it may not be able to liquidate ETN holdings at the desired time or price.

The Fund may invest in ETNs for which an affiliate of the Adviser provides certain index selection and marketing services. As a result, an affiliate of the Adviser may be paid service fees that are indirectly incurred by the Fund and its shareholders (in addition to Fund expenses). The Adviser will voluntarily waive a portion of its management fee to the extent that the Fund’s share of service fees paid to affiliates of the Adviser are attributable to investment in such an ETN.

Risks of Commodity-Linked Investments. Commodity-linked investments are considered speculative and have substantial risks, including the risk of loss of a significant portion of their principal value. Prices of commodities and commodity-linked investments may fluctuate significantly over short periods due to a variety of factors, including for example agricultural, economic and regulatory developments. These risks may make commodity-linked investments more volatile than other types of investments. The tax treatment of commodity-linked investments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level.

Risks of Mining & Metal Industry Securities. Investments in mining and metal industry companies may be speculative and may be subject to greater price volatility than investments in other types of companies. The special risks of mining and metal industry investments include:

changes in international monetary policies or economic and political conditions can affect the supply of gold and precious metals and consequently the value of mining and metal company investments;

the United States or foreign governments may pass laws or regulations limiting metal investments for strategic or other policy reasons;

the principal supplies of gold are concentrated in only five countries or territories: Australia, Canada, Russia and certain other former Soviet Union countries, South Africa and the United States, the governments of which may pass laws or regulations limiting metal investments for strategic or other policy reasons; and

increased environmental or labor costs may depress the value of mining and metal investments.

Principal Investment Strategies of the Fund

The Fund seeks to achieve its investment objective by investing in alternative (or non-traditional) asset classes and investment strategies, including but not limited to the following:

Fundamental and quantitatively driven alpha strategies, such as global macro (investment across broad asset and/or sector classes), equity long/short, currency and volatility arbitrage strategies
Real assets, such as commodities, gold and other precious metals and minerals, real estate and master limited partnerships (MLPs)
Income alternatives, such as event-linked securities and loans

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Asset Allocation Risk. Because the Fund typically invests in a combination of securities, the Fund’s ability to achieve its investment objective depends largely upon selecting the best mix of investments. There is the risk that the portfolio manager’s evaluations and assumptions regarding market conditions may be incorrect. During periods of rapidly rising stock prices, the Fund might not achieve growth in its share prices to the same degree as funds focusing only on stocks. The Fund’s investments in stocks may make it more difficult to preserve principal during periods of stock market volatility. The Fund’s use of a particular investment style might not be successful when that style is out of favor and the Fund’s performance may be adversely affected by the asset allocation decisions.

Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risks of Alternative Investment Strategies. The Fund utilizes alternative investment strategies, which are strategies that the portfolio managers expect to result in investment performance that does not correlate with the performance of traditional asset classes, such as equity and fixed-income investments. The Fund also seeks to utilize a diverse mix of alternative investment strategies, in the hope that individual strategies yield low performance correlation to other alternative investment strategies used by the Fund. However, alternative investments may be more volatile or illiquid, particularly during periods of market instability, and the Fund cannot guarantee that diverse alternative investment strategies will yield uncorrelated performance under all market conditions. In addition, the particular mix of alternative investments in the Fund’s portfolio may not be sufficiently diversified. The Fund is subject to the risk that its alternative investments may undergo a correlation shift, resulting in returns that are correlated with the broader market and/or with the Fund’s other alternative investments.

Liquidity Risks. Securities that are difficult to value or to sell promptly at an acceptable price are generally referred to as “illiquid” securities. If it is required to sell securities quickly or at a particular time (including sales to meet redemption requests) the Fund could realize a loss on illiquid investments.

Risks of Other Equity Securities. Most convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines. They may have more limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Small- and mid-cap companies may have unseasoned management or less depth in management skill than larger, more established companies. They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all.

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Risks of Event-Linked Securities. Event-linked securities (including “catastrophe” bonds and other insurance-linked securities) are fixed income securities for which the return of principal and payment of interest is contingent on the non-occurrence of a trigger event, such as a hurricane, earthquake, or other catastrophe or series of catastrophe events that leads to physical or economic loss(es). If the trigger event occurs prior to maturity, the Fund may lose all or a portion of its principal and additional interest. Event-linked securities may expose the Fund to certain other risks, including issuer default, adverse regulatory or jurisdictional interpretations, liquidity risk and adverse tax consequences.

Risks of Inflation-Protected Debt Securities. Inflation-indexed bonds, including Treasury Inflation-Protected Securities (TIPS), are fixed income securities whose principal value is periodically adjusted according to an identified rate of inflation. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds with similar maturities. If inflation declines, the principal amount or the interest rate of an inflation-indexed bond will be adjusted downward. This will result in reduced income and may result in a decline in the bond’s price which could cause losses for the Fund. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal or interest rate is adjusted for inflation. Inflation-indexed bonds normally will decline in price when real interest rates rise which could cause losses for the fund.

Risks of Exchange-Traded Notes (ETNs). ETNs are senior, unsecured, unsubordinated debt securities traded on an exchange (e.g., the NYSE) whose returns are linked to the performance of a particular market index or strategy, minus applicable fees. ETNs are subject to credit risk, and the value of an ETN may drop due to a downgrade in the issuer’s credit rating. An ETN may lose all or a portion of its value if the issuer fails. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in applicable interest rates, and economic, legal, political or geographic events that affect the underlying assets on which the index is based. The Fund may invest substantially in ETNs that are subject to the risks associated with industry or sector concentration. When the Fund invests in an ETN it will bear its proportionate share of the fees and expenses borne by the ETN, which will reduce the return realized at maturity or upon redemption. The Fund’s decision to sell ETN holdings may be limited by the availability of a secondary market and it may not be able to liquidate ETN holdings at the desired time or price.

The Fund may invest in ETNs for which an affiliate of the Adviser provides certain index selection and marketing services. As a result, an affiliate of the Adviser may be paid service fees that are indirectly incurred by the Fund and its shareholders (in addition to Fund expenses). The Adviser will voluntarily waive a portion of its management fee to the extent that the Fund’s share of service fees paid to affiliates of the Adviser are attributable to investment in such an ETN.

Risks of Commodity-Linked Investments. Commodity-linked investments are considered speculative and have substantial risks, including the risk of loss of a significant portion of their principal value. Prices of commodities and commodity-linked investments may fluctuate significantly over short periods due to a variety of factors, including for example agricultural, economic and regulatory developments. These risks may make commodity-linked investments more volatile than other types of investments. The tax treatment of commodity-linked investments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level.

Risks of Mining & Metal Industry Securities. Investments in mining and metal industry companies may be speculative and may be subject to greater price volatility than investments in other types of companies. The special risks of mining and metal industry investments include:

changes in international monetary policies or economic and political conditions can affect the supply of gold and precious metals and consequently the value of mining and metal company investments;

the United States or foreign governments may pass laws or regulations limiting metal investments for strategic or other policy reasons;

the principal supplies of gold are concentrated in only five countries or territories: Australia, Canada, Russia and certain other former Soviet Union countries, South Africa and the United States, the governments of which may pass laws or regulations limiting metal investments for strategic or other policy reasons; and

increased environmental or labor costs may depress the value of mining and metal investments.

The Fund’s use of a particular investment style might not be successful when that style is out of favor and the Fund’s performance may be adversely affected by the asset allocation decisions.

Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

The Fund also seeks to utilize a diverse mix of alternative investment strategies, in the hope that individual strategies yield low performance correlation to other alternative investment strategies used by the Fund. However, alternative investments may be more volatile or illiquid, particularly during periods of market instability, and the Fund cannot guarantee that diverse alternative investment strategies will yield uncorrelated performance under all market conditions.

Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines.

They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all.

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Risks of Event-Linked Securities. Event-linked securities (including “catastrophe” bonds and other insurance-linked securities) are fixed income securities for which the return of principal and payment of interest is contingent on the non-occurrence of a trigger event, such as a hurricane, earthquake, or other catastrophe or series of catastrophe events that leads to physical or economic loss(es). If the trigger event occurs prior to maturity, the Fund may lose all or a portion of its principal and additional interest. Event-linked securities may expose the Fund to certain other risks, including issuer default, adverse regulatory or jurisdictional interpretations, liquidity risk and adverse tax consequences.

Risks of Inflation-Protected Debt Securities. Inflation-indexed bonds, including Treasury Inflation-Protected Securities (TIPS), are fixed income securities whose principal value is periodically adjusted according to an identified rate of inflation. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds with similar maturities. If inflation declines, the principal amount or the interest rate of an inflation-indexed bond will be adjusted downward. This will result in reduced income and may result in a decline in the bond’s price which could cause losses for the Fund. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal or interest rate is adjusted for inflation. Inflation-indexed bonds normally will decline in price when real interest rates rise which could cause losses for the fund.

Risks of Exchange-Traded Notes (ETNs). ETNs are senior, unsecured, unsubordinated debt securities traded on an exchange (e.g., the NYSE) whose returns are linked to the performance of a particular market index or strategy, minus applicable fees. ETNs are subject to credit risk, and the value of an ETN may drop due to a downgrade in the issuer’s credit rating. An ETN may lose all or a portion of its value if the issuer fails. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in applicable interest rates, and economic, legal, political or geographic events that affect the underlying assets on which the index is based. The Fund may invest substantially in ETNs that are subject to the risks associated with industry or sector concentration. When the Fund invests in an ETN it will bear its proportionate share of the fees and expenses borne by the ETN, which will reduce the return realized at maturity or upon redemption. The Fund’s decision to sell ETN holdings may be limited by the availability of a secondary market and it may not be able to liquidate ETN holdings at the desired time or price.

The Fund may invest in ETNs for which an affiliate of the Adviser provides certain index selection and marketing services. As a result, an affiliate of the Adviser may be paid service fees that are indirectly incurred by the Fund and its shareholders (in addition to Fund expenses). The Adviser will voluntarily waive a portion of its management fee to the extent that the Fund’s share of service fees paid to affiliates of the Adviser are attributable to investment in such an ETN.

Risks of Commodity-Linked Investments. Commodity-linked investments are considered speculative and have substantial risks, including the risk of loss of a significant portion of their principal value. Prices of commodities and commodity-linked investments may fluctuate significantly over short periods due to a variety of factors, including for example agricultural, economic and regulatory developments. These risks may make commodity-linked investments more volatile than other types of investments. The tax treatment of commodity-linked investments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level.

Risks of Mining & Metal Industry Securities. Investments in mining and metal industry companies may be speculative and may be subject to greater price volatility than investments in other types of companies. The special risks of mining and metal industry investments include:

changes in international monetary policies or economic and political conditions can affect the supply of gold and precious metals and consequently the value of mining and metal company investments;

the United States or foreign governments may pass laws or regulations limiting metal investments for strategic or other policy reasons;

the principal supplies of gold are concentrated in only five countries or territories: Australia, Canada, Russia and certain other former Soviet Union countries, South Africa and the United States, the governments of which may pass laws or regulations limiting metal investments for strategic or other policy reasons; and

increased environmental or labor costs may depress the value of mining and metal investments.

Principal Investment Strategies of the Fund

The Fund invests mainly in common stock of U.S. and foreign companies. The Fund can invest without limit in foreign securities and can invest in any country, including countries with developing or emerging markets. However, the Fund currently emphasizes its investments in developed markets such as the United States, Western European countries and Japan. The Fund does not limit its investments to companies in a particular market capitalization range, but primarily invests in mid- and large-cap companies.

Under normal market conditions, the Fund will invest in at least three different countries (one of which may be the United States). Typically, the Fund invests in a number of different countries. The Fund is not required to allocate its investments in any set percentages in any particular countries.

The portfolio managers primarily look for quality companies, regardless of domicile, that have sustainable growth. Their investment approach combines a thematic approach to idea generation with bottom-up, fundamental company analysis. The portfolio managers seek to identify secular changes in the world and look for pockets of durable change that they believe will drive global growth for the next decade. These large scale structural themes are referred to collectively as MANTRA^®: Mass Affluence, New Technology, Restructuring, and Aging. The portfolio managers do not target a fixed allocation with regard to any particular theme, and may choose to focus on various sub-themes within each theme. Within each sub-theme, the portfolio managers employ fundamental company analysis to select investments for the Fund’s portfolio. The economic characteristics they seek include a combination of high return on invested capital, good cash flow characteristics, high barriers to entry, dominant market share, a strong competitive position, talented management, and balance sheet strength that the portfolio managers believe will enable the company to fund its own growth. These criteria may vary. The portfolio managers also consider how industry dynamics, market trends and general economic conditions may affect a company’s earnings outlook.

The portfolio managers have a long-term investment horizon of typically three to five years. They also have a contrarian buy discipline; they buy high quality companies that fit their investment criteria when their valuations underestimate their long-term earnings potential. For example, a company’s stock price may dislocate from its fundamental outlook due to a short-term earnings glitch or negative, short-term market sentiment, which can give rise to an investment opportunity. The portfolio managers monitor individual issuers for changes in earnings potential or other effects of changing market conditions that may trigger a decision to sell a security, but do not require a decision to do so.

Principal Investment Strategies of the Fund

The Fund invests mainly in debt securities in three market sectors: Foreign governments and issuers, U.S. government securities, and lower-grade, high-yield securities of U.S. and foreign issuers (commonly referred to as “junk bonds”). A debt security is a security representing money borrowed by the issuer that must be repaid. The terms of a debt security specify the amount of principal, the interest rate or discount, and the time or times at which payments are due.

Under normal market conditions, the Fund invests in each of the three market sectors. However, the Fund is not required to invest in all three sectors at all times, and the amount of its assets in each of the three sectors will vary over time. The Fund can invest up to 100% of its assets in any one sector at any time, if the Fund’s portfolio managers believe that it offers the best investment opportunity. Under normal market conditions, the Fund will invest a substantial portion of its assets in a number of different countries, including the U.S. The Fund is not required to allocate its investments in any set percentages in any particular countries. The Fund may also invest in securities outside of these three market sectors, as further described in the prospectus and the Fund’s Statement of Additional Information.

The Fund’s foreign investments may include debt securities issued by foreign governments or companies in both developed markets and emerging markets. The Fund has no limitations regarding the range of maturities of the debt securities it can buy or the market capitalization of the issuers of those securities.

The Fund’s debt investments typically include: U.S. and foreign government bonds and notes, collateralized mortgage obligations (CMOs) and other mortgage-related securities, domestic and foreign corporate debt obligations, “structured” notes, “zero coupon” and “stripped” securities, participation interests in loans, investments in loan pools and asset-backed securities. The Fund normally invests a substantial amount of its assets in lower-grade, high-yield debt securities, and can do so without limit.

The Fund can invest in investment grade or lower-grade, high-yield debt securities. “Investment grade” debt securities are rated in one of the top four rating categories by nationally recognized statistical rating organizations such as Moody’s Investors Service or S&P Global Ratings. The Fund may also invest in unrated securities, in which case the Fund’s investment adviser, Invesco may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Adviser’s credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. Although the Fund normally invests a substantial portion of its assets in lower-grade, high-yield debt securities, it can buy investment-grade debt securities without limit.

The Fund may also use certain types of derivative instruments for investment purposes or for hedging, including: options, futures, forward contracts, swaps, certain mortgage-related securities, “structured” notes, and event-linked bonds.

The Fund actively manages foreign currency exposure to seek to reduce risk and enhance return. To do so, the Fund may invest in foreign exchange derivatives, including forwards and options that reference foreign currencies, including currencies of developing and emerging market countries.

The portfolio managers analyze the overall investment opportunities and risks among the three market sectors in which the Fund invests and seek to moderate the special risks of investing in lower-grade, high-yield debt instruments and foreign securities by building a broadly diversified portfolio. The Fund’s diversification strategies are intended to help reduce share price volatility while seeking current income. The portfolio managers currently focus on securities offering a balance of income and total return, securities whose market prices tend to move in different directions (to seek overall portfolio diversification), and relative values among the three market sectors in which the Fund invests. These factors may vary in particular cases and may change over time.

The Fund may sell securities that the portfolio managers believe are no longer favorable based on these factors.

The Fund may invest up to 25% of its total assets in a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the Subsidiary). The Subsidiary invests primarily in Regulation S securities. Regulation S securities are securities of U.S. and non-U.S. issuers that are issued through private offerings without registration with the Securities and Exchange Commission pursuant to Regulation S under the Securities Act of 1933. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include the Fund’s indirect investments through the Subsidiary.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Because the Fund can invest without limit in below-investment-grade securities, the Fund’s credit risks are greater than those of funds that buy only investment-grade securities.

Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks. Mortgage-backed securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities. In addition, a substantial portion of the Fund’s assets may be subject to “forward roll” transactions (also referred to as “mortgage dollar rolls”) at any given time, which subject the Fund to the risk that market value of the mortgage-related securities involved might decline, and that the counterparty might default in its obligations.

Sector Allocation Risk. In allocating investments among its three principal market sectors, the Fund seeks to take advantage of the potential lack of performance correlation between those sectors. There is the risk that the evaluations regarding the sectors’ relative performance may be incorrect and those sectors may all perform in a similar manner under certain market conditions.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives are required to be executed on a regulated market and/or cleared through a clearinghouse. Entering into a derivative transaction with a clearinghouse may entail further risks and costs.

Risks of Investments in the Fund’s Wholly-Owned Subsidiary. The Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to its investor protections (except as otherwise noted in this prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Subsidiary is wholly-owned and controlled by the Fund and managed by the Adviser. Therefore, the Fund’s ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders. In addition, changes in the laws of the United States and/or the Cayman Islands (where the Subsidiary is incorporated) could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information and could adversely affect the Fund. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the performance of the Fund and/or the Subsidiary. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.

Risks of Investing in Regulation S Securities. Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Risks of Senior Loans and Other Loans. The Fund may invest in loans, and in particular, in floating rate loans (sometimes referred to as “adjustable rate loans”) that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as “Senior Loans.” Loans may be collateralized or uncollateralized. They typically pay interest at rates that are reset periodically based on a reference benchmark that reflects current interest rates, plus a margin or premium. In addition to the risks typically associated with debt securities, such as credit and interest rate risk, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders’ security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans are expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interests rates do and therefore should more closely track market movements in interest rates.

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund’s ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences.

To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund’s ability to pay redemption proceeds in a timely manner may be adversely affected, as well as the Fund’s performance.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity’s credit risk), in addition to the exposure the Fund has to the creditworthiness of the borrower.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

Risks of Investments in Other Investment Companies. As an investor in another investment company, the Fund would be subject to the risks of that investment company’s portfolio. Investing in another investment company may also involve paying a premium above the value of that investment company’s portfolio securities and is subject to a ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the payment of any premiums, expenses or sales charges. The Investment Company Act of 1940 also imposes limitations on mutual funds’ investments in other investment companies.

The Fund may also invest in exchange-traded funds (ETFs), which are subject to all the risks of investing in investment companies as described above. Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, shares of ETFs potentially may trade at a discount or a premium to their net asset value. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

Principal Risks of Investing in the Fund

rr_RiskNarrativeTextBlock

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Because the Fund can invest without limit in below-investment-grade securities, the Fund’s credit risks are greater than those of funds that buy only investment-grade securities.

Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks. Mortgage-backed securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities.

Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries.

Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940.

Changes in the laws of the United States and/or the Cayman Islands could adversely affect the performance of the Fund and/or the Subsidiary. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.

Risks of Investing in Regulation S Securities. Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Risks of Senior Loans and Other Loans. The Fund may invest in loans, and in particular, in floating rate loans (sometimes referred to as “adjustable rate loans”) that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as “Senior Loans.” Loans may be collateralized or uncollateralized. They typically pay interest at rates that are reset periodically based on a reference benchmark that reflects current interest rates, plus a margin or premium. In addition to the risks typically associated with debt securities, such as credit and interest rate risk, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders’ security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans are expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interests rates do and therefore should more closely track market movements in interest rates.

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund’s ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences.

To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund’s ability to pay redemption proceeds in a timely manner may be adversely affected, as well as the Fund’s performance.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity’s credit risk), in addition to the exposure the Fund has to the creditworthiness of the borrower.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

Risks of Investments in Other Investment Companies. As an investor in another investment company, the Fund would be subject to the risks of that investment company’s portfolio. Investing in another investment company may also involve paying a premium above the value of that investment company’s portfolio securities and is subject to a ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the payment of any premiums, expenses or sales charges. The Investment Company Act of 1940 also imposes limitations on mutual funds’ investments in other investment companies.

The Fund may also invest in exchange-traded funds (ETFs), which are subject to all the risks of investing in investment companies as described above. Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, shares of ETFs potentially may trade at a discount or a premium to their net asset value. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

Principal Investment Strategies of the Fund

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Because the Fund can invest without limit in below-investment-grade securities, the Fund’s credit risks are greater than those of funds that buy only investment-grade securities.

Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks. Mortgage-backed securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities. In addition, a substantial portion of the Fund’s assets may be subject to “forward roll” transactions (also referred to as “mortgage dollar rolls”) at any given time, which subject the Fund to the risk that market value of the mortgage-related securities involved might decline, and that the counterparty might default in its obligations.

Sector Allocation Risk. In allocating investments among its three principal market sectors, the Fund seeks to take advantage of the potential lack of performance correlation between those sectors. There is the risk that the evaluations regarding the sectors’ relative performance may be incorrect and those sectors may all perform in a similar manner under certain market conditions.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives are required to be executed on a regulated market and/or cleared through a clearinghouse. Entering into a derivative transaction with a clearinghouse may entail further risks and costs.

Risks of Investments in the Fund’s Wholly-Owned Subsidiary. The Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to its investor protections (except as otherwise noted in this prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Subsidiary is wholly-owned and controlled by the Fund and managed by the Adviser. Therefore, the Fund’s ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders. In addition, changes in the laws of the United States and/or the Cayman Islands (where the Subsidiary is incorporated) could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information and could adversely affect the Fund. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the performance of the Fund and/or the Subsidiary. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.

Risks of Investing in Regulation S Securities. Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Risks of Senior Loans and Other Loans. The Fund may invest in loans, and in particular, in floating rate loans (sometimes referred to as “adjustable rate loans”) that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as “Senior Loans.” Loans may be collateralized or uncollateralized. They typically pay interest at rates that are reset periodically based on a reference benchmark that reflects current interest rates, plus a margin or premium. In addition to the risks typically associated with debt securities, such as credit and interest rate risk, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders’ security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans are expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interests rates do and therefore should more closely track market movements in interest rates.

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund’s ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences.

To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund’s ability to pay redemption proceeds in a timely manner may be adversely affected, as well as the Fund’s performance.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity’s credit risk), in addition to the exposure the Fund has to the creditworthiness of the borrower.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

Risks of Investments in Other Investment Companies. As an investor in another investment company, the Fund would be subject to the risks of that investment company’s portfolio. Investing in another investment company may also involve paying a premium above the value of that investment company’s portfolio securities and is subject to a ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the payment of any premiums, expenses or sales charges. The Investment Company Act of 1940 also imposes limitations on mutual funds’ investments in other investment companies.

The Fund may also invest in exchange-traded funds (ETFs), which are subject to all the risks of investing in investment companies as described above. Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, shares of ETFs potentially may trade at a discount or a premium to their net asset value. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

Principal Risks of Investing in the Fund

rr_RiskNarrativeTextBlock

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Because the Fund can invest without limit in below-investment-grade securities, the Fund’s credit risks are greater than those of funds that buy only investment-grade securities.

Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks. Mortgage-backed securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities. In addition, a substantial portion of the Fund’s assets may be subject to “forward roll” transactions (also referred to as “mortgage dollar rolls”) at any given time, which subject the Fund to the risk that market value of the mortgage-related securities involved might decline, and that the counterparty might default in its obligations.

Sector Allocation Risk. In allocating investments among its three principal market sectors, the Fund seeks to take advantage of the potential lack of performance correlation between those sectors. There is the risk that the evaluations regarding the sectors’ relative performance may be incorrect and those sectors may all perform in a similar manner under certain market conditions.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives are required to be executed on a regulated market and/or cleared through a clearinghouse. Entering into a derivative transaction with a clearinghouse may entail further risks and costs.

Risks of Investments in the Fund’s Wholly-Owned Subsidiary. The Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to its investor protections (except as otherwise noted in this prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Subsidiary is wholly-owned and controlled by the Fund and managed by the Adviser. Therefore, the Fund’s ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders. In addition, changes in the laws of the United States and/or the Cayman Islands (where the Subsidiary is incorporated) could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information and could adversely affect the Fund. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the performance of the Fund and/or the Subsidiary. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.

Risks of Investing in Regulation S Securities. Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Risks of Senior Loans and Other Loans. The Fund may invest in loans, and in particular, in floating rate loans (sometimes referred to as “adjustable rate loans”) that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as “Senior Loans.” Loans may be collateralized or uncollateralized. They typically pay interest at rates that are reset periodically based on a reference benchmark that reflects current interest rates, plus a margin or premium. In addition to the risks typically associated with debt securities, such as credit and interest rate risk, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders’ security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans are expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interests rates do and therefore should more closely track market movements in interest rates.

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund’s ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences.

To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund’s ability to pay redemption proceeds in a timely manner may be adversely affected, as well as the Fund’s performance.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity’s credit risk), in addition to the exposure the Fund has to the creditworthiness of the borrower.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

Risks of Investments in Other Investment Companies. As an investor in another investment company, the Fund would be subject to the risks of that investment company’s portfolio. Investing in another investment company may also involve paying a premium above the value of that investment company’s portfolio securities and is subject to a ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the payment of any premiums, expenses or sales charges. The Investment Company Act of 1940 also imposes limitations on mutual funds’ investments in other investment companies.

The Fund may also invest in exchange-traded funds (ETFs), which are subject to all the risks of investing in investment companies as described above. Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, shares of ETFs potentially may trade at a discount or a premium to their net asset value. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

Principal Investment Strategies of the Fund

Under normal circumstances, the Fund will invest at least 65% of its total assets in equity securities of issuers that are domiciled or that have their primary operations in at least three different countries outside of the United States and may invest 100% of its total assets in foreign companies. The Fund mainly invests in “growth companies,” which are companies whose earnings and stock prices are expected to increase at a faster rate than the overall market.

The Fund may invest up to 25% of its total assets in emerging markets. It considers an issuer to be located in an emerging market if it is organized under the laws of an emerging country; its principal securities trading market is in an emerging market; or at least 50% of the issuer’s non-current assets, capitalization, gross revenue or profit is derived from assets or activities located in emerging markets (directly or indirectly). From time to time, the Fund may place greater emphasis on investing in one or more particular industries, countries, or regions, such as Asia, Europe or Latin America.

The Fund’s portfolio managers look primarily for high growth potential using a “bottom up” investment approach on a company-by-company basis. That approach looks at the investment performance of individual stocks before considering the impact of general or industry specific economic trends. It includes fundamental analysis of a company’s financial statements and management structure and consideration of the company’s operations and product development, as well as its position in its industry.

The portfolio managers currently focus on the following factors: companies that enjoy a strong competitive position and high demand for their products or services; companies with accelerating earnings growth and cash flow; and diversity among countries, companies and industries to seek to reduce the risks of foreign investing, such as currency fluctuations and market volatility. The consideration of those factors may vary in particular cases and may change over time.

The portfolio managers also consider the effects of worldwide trends on the growth of particular business sectors and looks for companies that may benefit from those trends. The trends currently considered include: mass affluence, new technologies, restructuring and aging. The portfolio managers do not invest any fixed amount of the Fund’s assets according to these criteria, which may change over time. The portfolio managers monitor individual issuers for changes in these factors, which may trigger, but does not require, a decision to sell a security.

The Fund does not limit its investments to issuers within a specific market capitalization range and at times may invest in both smaller, less-well-known companies and larger, more established companies that the portfolio managers believe have favorable prospects for capital growth relative to the market. The Fund currently invests a substantial portion of its assets in stocks of small- to mid-sized companies. The price of those stocks may be more volatile than the price of stocks issued by larger companies.

The Fund primarily invests in common stock but may also buy preferred stocks, securities convertible into common stocks and other securities having equity features. The Fund typically does not invest in debt securities to a significant degree but can invest up to 20% of its total assets in debt securities when the portfolio managers believe that it is appropriate to do so in order to seek the Fund’s objective. The Fund can invest up to 15% of its total assets in debt securities that are below investment grade, commonly referred to as “junk bonds.”

The Fund can also use derivative instruments, such as options, futures, forwards and swaps, to seek higher investment returns or to try to manage investment risks.

Principal Investment Strategies of the Fund

The Fund mainly invests in common stocks of U.S. companies of different capitalization ranges. The Fund currently focuses on “larger capitalization” issuers, which are considered to be companies with market capitalizations equal to the companies in the Russell 1000 Index. The portfolio managers use fundamental research to select securities for the Fund’s portfolio, which is comprised of both growth and value stocks. While the process may change over time or vary in particular cases, in general the selection process currently uses a fundamental approach in analyzing issuers on factors such as a company’s financial performance, company strength and prospects, industry position, and business model and management strength. Industry outlook, market trends and general economic conditions may also be considered.

The portfolio is constructed and regularly monitored based upon several analytical tools, including quantitative investment models. Quantitative models are used as part of the idea generation process to rank securities within each sector to identify potential buy and sell candidates for further fundamental analysis. The Fund aims to maintain a broadly diversified portfolio across major economic sectors by applying investment parameters for both sector and position size. The portfolio managers use the following sell criteria: the stock price is approaching its target, deterioration in the company’s competitive position, poor execution by the company’s management, or identification of more attractive alternative investment ideas.

Principal Investment Strategies of the Fund

Under normal market conditions, the Fund will invest at least 80% of its net assets, including any borrowings for investment purposes, in securities of “small-cap” companies, and in derivatives and other instruments that have economic characteristics similar to such securities. A company’s “market capitalization” is the value of its outstanding common stock. The Fund considers small-cap companies to be those having a market capitalization in the range of the Russell 2000^® Index. The capitalization range of that index is subject to change at any time due to market activity or changes in the composition of the index. The range of the Russell 2000^® Index generally widens over time and it is reconstituted annually to preserve its market cap characteristics. The Fund measures a company’s capitalization at the time the Fund buys a security and is not required to sell a security if the company’s capitalization moves outside of the Fund’s capitalization definition. Although the Fund mainly invests in U.S. companies, it can invest in securities issued by companies or governments in any country. The Fund primarily invests in common stock but may also invest in other types of securities that are consistent with its investment objective.

The portfolio managers use fundamental research to select securities for the Fund’s portfolio. While the process may change over time or vary in particular cases, in general the selection process currently uses a fundamental approach in analyzing issuers on factors such as a company’s financial performance, competitive strength and prospects, industry position, and business model and management strength. Industry outlook, market trends and general economic conditions may also be considered.

The Fund aims to maintain a broad diversification across all major economic sectors. The portfolio is constructed and regularly monitored based upon several analytical tools, including quantitative investment models. Quantitative models are used as part of the idea generation process to rank securities within each sector to identify potential buy and sell candidates for further fundamental analysis.

In constructing the portfolio, the Fund seeks to limit exposure to so-called “top-down” or “macro” risks, such as overall stock market movements, economic cycles, and interest rate or currency fluctuations. Instead, the portfolio managers seek to add value by selecting individual securities with superior company-specific fundamental attributes or relative valuations that they expect to outperform their industry and sector peers. This is commonly referred to as a “bottom-up” approach to portfolio construction.

The portfolio managers consider stock rankings, benchmark weightings and capitalization outlooks in determining security weightings for individual issuers. The portfolio managers might sell a security if the price is approaching their price target, if the company’s competitive position has deteriorated or the company’s management has performed poorly, or if they have identified more attractive investment prospects.

Principal Investment Strategies of the Fund

Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in investment-grade debt securities (generally referred to as “bonds”). A debt security is a security representing money borrowed by the issuer that must be repaid. The terms of a debt security specify the amount of principal, the interest rate or discount, and the time or times at which payments are due. Debt securities can include:

Domestic and foreign corporate debt obligations;
Domestic and foreign government debt obligations, including U.S. government securities;
Mortgage-related securities;
Asset-backed securities; and
Other debt obligations.

The portfolio managers’ overall strategy is to build a diversified portfolio of corporate and government bonds. The Fund’s investments in U.S. government securities may include securities issued or guaranteed by the U.S. government or by its agencies or federally-chartered entities referred to as “instrumentalities.” There is no required allocation of the Fund’s assets among the classes of securities, but the Fund focuses mainly on U.S. government securities and investment-grade corporate debt securities. When market conditions change, the portfolio managers might change the Fund’s relative asset allocation.

The Fund can invest up to 20% of its total assets in lower-grade, high-yield debt securities that are below investment-grade (commonly referred to as “junk bonds”). “Investment-grade” debt securities are rated in one of the top four rating categories by nationally recognized statistical rating organizations such as Moody’s or S&P Global Ratings. The Fund may also invest in unrated securities, in which case the Fund’s investment adviser, Invesco may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Adviser’s credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization.

The Fund has no limitations on the range of maturities of the debt securities in which it can invest and may hold securities with short-, medium- or long-term maturities. The maturity of a security differs from its effective duration, which attempts to measure the expected volatility of a security’s price to interest rate changes. For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the bond’s value to decrease about 3%. To try to decrease volatility, the Fund seeks to maintain a weighted average effective portfolio duration of three to six years, measured on a dollar-weighted basis using the effective duration of the securities included in its portfolio and the amount invested in each of those securities. However, the duration of the portfolio might not meet that target due to market events or interest rate changes that cause debt securities to be repaid more rapidly or more slowly than expected.

The Fund may invest in foreign debt securities, including securities issued by foreign governments or companies in both developed and emerging markets.

The Fund may also use derivatives to seek increased returns or to try to manage investment risks. Futures, swaps and “structured” notes are examples of some of the types of derivatives the Fund can use.

In selecting investments for the Fund, the Fund’s portfolio managers analyze the overall investment opportunities and risks in different sectors of the debt securities markets by focusing on business cycle analysis and relative values between the corporate and government sectors. The Fund mainly seeks income earnings on the Fund’s investments plus capital appreciation that may arise from decreases in interest rates, from improving credit fundamentals for a particular sector or security or from other investment techniques.

The Fund may sell securities that the portfolio managers believe no longer meet the above criteria.

Principal Investment Strategies of the Fund

The Fund is a money market fund that intends to qualify as a “government money market fund,” in connection with the amendments adopted by the U.S. Securities and Exchange Commission to Rule 2a-7 and other rules governing money market funds under the Investment Company Act of 1940, as amended. As a government money market fund, the Fund must invest at least 99.5% of its total assets in cash, government securities and/or repurchase agreements that are “collateralized fully” (i.e., backed by cash or government securities). The securities in which the Fund invests may have fixed, floating or variable interest rates. The Fund may also invest in affiliated and unaffiliated government money market funds. Additionally, as a government money market fund, the Fund is not required to impose a liquidity fee and/or temporary redemption gate if the Fund’s weekly liquid assets fall below 30% of its total assets. While the Fund’s Board may elect to subject the Fund to liquidity fee and gate requirements in the future, it has not elected to do so at this time.

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings, if any, for investment purposes) in government securities and repurchase agreements that are collateralized by government securities. The 80% investment policy is a non-fundamental investment policy and will not be changed without 60 days’ advance notice to shareholders.

Principal Risks of Investing in the Fund

All investments carry risks to some degree. The Fund’s investments are subject to changes in their value from a number of factors. However, the Fund’s investments must meet the special rules under federal law for money market funds. Those requirements relate to high credit quality, a short average maturity and diversification of the Fund’s investments among issuers. Those provisions are designed to help minimize credit risks, to reduce the effects of changes in prevailing interest rates and to reduce the effect on the Fund’s portfolio of a default by any one issuer. Since income on short-term securities tends to be lower than income on longer-term debt securities, the Fund’s yield will likely be lower than the yield on longer-term fixed-income funds.

Even so, there are risks that an issuer of an obligation that the Fund holds might have its credit rating downgraded or might default on its obligations, or that interest rates might rise sharply, causing the value of the Fund’s investments to fall. Also, there is the risk that the value of your investment could be eroded over time by the effects of inflation, or that poor security selection could cause the Fund to underperform other funds that have a similar objective. If there is an unexpectedly high demand for the redemption of Fund shares, the Fund might need to sell portfolio securities prior to their maturity, possibly at a loss. As a result, there is a risk that the Fund’s shares could fall below $1.00 per share.

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

Risks of Money Market Instruments. Money market instruments may be subject to interest rate risk, credit risk, extension risk, reinvestment risk, prepayment risk, and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and they may be worth less than the amount the Fund paid for them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows.

Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities.

Extension risk is the risk that an increase in interest rates could cause principal payments on a debt security to be repaid at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value.

Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds.

Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell securities at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the securities’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders, which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, as was the case during the latter half of 2008 and early 2009, those concerns could cause reduced liquidity in certain debt securities markets. A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac) or other Government Sponsored Enterprises (GSEs)). U.S. government securities are subject to market risk, interest rate risk and credit risk. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Risks of Repurchase Agreements. In a repurchase transaction, the Fund buys a security and simultaneously sells it back to the vendor for delivery at a future date. If the seller fails to pay the repurchase price on the delivery date, the Fund may incur costs in disposing of the collateral and may experience losses if there is any delay in its ability to do so. If the default on the part of the seller is due to its bankruptcy, the Fund’s ability to liquidate the collateral may be delayed or limited.

Net Asset Value Risk. There is no assurance that the Fund will maintain a net asset value of $1.00 per share on a continuous basis. Additionally, there can be no assurance that the Fund’s affiliates will purchase assets from the Fund that become distressed (if any), make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a net asset value of $1.00 per share. The failure of any money market fund to maintain a stable net asset value, could place increased redemption pressure on other money market funds, including the Fund.

Regulatory Risk. Changes to the monetary policy by the Federal Reserve or other regulatory actions could expose fixed income and related markets to heightened volatility, interest rate sensitivity and reduced liquidity, which may impact the Fund’s operations, universe of potential investment options, and return potential.

Yield Risk. During periods of extremely low short-term interest rates, the Fund may not be able to maintain a positive yield. The rate of the Fund’s income will vary from day to day, generally reflecting changes in short-term interest rates and in the fixed-income securities market. There is no assurance that the Fund will achieve its investment objective.

Cash Risk. As a government money market fund, the Fund will likely hold some of its assets in cash, which may negatively affect the Fund’s performance. Maintaining cash positions may also subject the Fund to additional risks and costs, such as increased exposure to the custodian bank holding the assets and any fees imposed for large cash balances.

Risk of Investing in Floating and Variable Rate Obligations. Some fixed-income securities have variable or floating interest rates that provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the stated prevailing market rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the securities at any given time. Such securities also may lose value.

Large Shareholder Transactions Risk. Large transactions by shareholders can impact the Fund’s expense ratio, yield and potentially its net asset value. A large redemption of Fund shares by a large shareholder may have a negative effect on the Fund’s net asset value and yield, as the Fund may be forced to sell a large portion of its portfolio holdings at an inopportune time. A large redemption of Fund shares may also result in an increase in the Fund’s expense ratio, since a large redemption may result in the Fund’s current expenses being allocated over a smaller asset base. In order to be able to meet reasonably foreseeable requests for redemptions of Fund shares, the Fund may be required to consider factors that could affect the Fund’s liquidity needs, including characteristics of the Fund’s investors and their likely redemptions. This may require the Fund to maintain sufficiently liquid assets in lower-yielding securities that are easier to sell, which may have a negative impact on the Fund’s yield. Similarly, a large purchase of Fund shares by a large shareholder may have a negative effect on the Fund’s yield, as the Fund may be unable to deploy a larger cash position into new investments as quickly as it could with a smaller cash position. Large transactions may also increase transaction costs.

The rate of the Fund’s income will vary from day to day, generally reflecting changes in short-term interest rates and in the fixed-income securities market. There is no assurance that the Fund will achieve its investment objective.

Performance Information

No performance information is available for the Fund because it has not yet completed a full calendar year of operations. In the future, the Fund will disclose performance information in a bar chart and performance table. Such disclosure will give some indication of the risks of an investment in the Fund by showing changes in the Fund’s performance from year to year. Past performance (before and after taxes) is not necessarily an indication of its future performance.

Principal Risks of Investing in the Fund

rr_RiskNarrativeTextBlock

Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities.

Extension risk is the risk that an increase in interest rates could cause principal payments on a debt security to be repaid at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value.

Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds.

Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.
