The Examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Examples also assume that your investment has a 5% return each year, that the Fund's operating expenses stay the same and that the fee waiver remains in effect as agreed upon. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 2398 2845 2055 1245 1239 815 832 647 369 528 278 77 PORTFOLIO TURNOVER The Fund pays transaction costs, such as commissions, when it buys or sells securities (or &#8220;turns over&#8221; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund's performance. During the most recent fiscal period, the Fund's portfolio turnover rate was 44% of the average value of its portfolio. PRINCIPAL STRATEGIES The Fund invests primarily in fixed-income securities, with an emphasis on corporate fixed-income securities rated below investment grade (high-yield securities or &#8220;junk bonds&#8221;), unrated securities considered by the Adviser to be of comparable quality, and related derivatives. Under normal circumstances, the Fund will maintain a dollar-weighted average duration of less than four years, although it may invest in individual fixed-income securities with durations in excess of four years.<br/><br/>The Fund may also invest in investment grade fixed-income securities, high-yield securities of governments and government-related issuers, loan participations and, to a lesser extent, equity securities, and derivatives related to these instruments. The Fund will not invest more than 10% of its net assets in securities rated at or below Caa1 by Moody's, CCC+ by S&amp;P or CCC by Fitch at time of purchase. (For this purpose of this 10% limit, the Fund will rely on the highest rating from any of the three rating agencies, and the notional amount of derivatives related to these instruments will be counted).<br/><br/>The Fund will invest on a global basis, including securities of issuers in both developed and emerging market countries. The Fund may invest in securities denominated in foreign currencies, although it expects to frequently use hedging instruments to attempt to limit the currency exposure resulting from such investments.<br/><br/>In selecting securities for purchase or sale by the Fund, the Adviser will attempt to take advantage of inefficiencies that it believes exist in the global fixed-income markets. These inefficiencies arise from investor behavior, market complexity, and the investment limitations to which investors are subject. The Adviser will combine its quantitative forecasts with fundamental economic and credit research in seeking to exploit these inefficiencies.<br/><br/>The Adviser will employ strategies to manage the Fund's volatility relative to the global high-yield market. Such strategies may include shortening the duration of the Fund, adding higher rated investments, investing in various fixed-income sectors with relatively low correlation among them, and using hedging strategies that seek to provide protection from substantial market downturns. The Adviser will utilize different combinations of the above strategies at different points in time, taking into consideration, among other factors, the shape of the credit curve, the relative effect on yield associated with changes in credit quality, and the cost of hedging strategies.<br/><br/>The Fund expects to use derivatives, such as options, futures, forwards and swaps, to a significant extent. Derivatives may provide more efficient and economical exposure to market segments than direct investments, and may also be a quicker and more efficient way to alter the Fund's exposure. For example, the Fund may use credit default and interest rate swaps to gain exposure to the fixed-income markets. In determining when and to what extent to enter into derivative transactions, the Adviser will consider factors such as the risks and returns of these investments relative to direct investments and the costs of such transactions. Derivatives such as options and forwards may also be used for hedging purposes, including to hedge against interest rate, credit market and currency fluctuations. PRINCIPAL RISKS <ul type = "square"><li>MARKET RISK: The value of the Fund's assets will fluctuate as the stock, bond, currency and commodity markets fluctuate. The value of the Fund's investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market.</li></ul><ul type = "square"><li>INTEREST RATE RISK: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations.</li></ul><ul type = "square"><li>DURATION RISK: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise. For example, a fixed-income security with a duration of three years will decrease in value by approximately 3% if interest rates increase by 1%.</li></ul><ul type = "square"><li>CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer, guarantor or counterparty may default causing a loss of the full principal amount of a security or the amount to which the Fund is entitled in a derivative transaction. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.</li></ul><ul type = "square"><li>BELOW INVESTMENT GRADE SECURITIES RISK: Investments in fixed-income securities with lower ratings, commonly known as &#8220;junk bonds&#8221;, tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the junk bond market generally and less secondary market liquidity.</li></ul><ul type = "square"><li>INFLATION RISK: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund's assets can decline as can the real value of the Fund's distributions.</li></ul><ul type = "square"><li>DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Fund, and may be subject to counterparty risk to a greater degree than more traditional investments.</li></ul><ul type = "square"><li>FOREIGN (NON-U.S.) RISK: Investments in securities of non-U.S. issuers may involve more risk than those of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors.</li></ul><ul type = "square"><li>EMERGING MARKET RISK: Investments in emerging market countries may have more risk because the markets are less developed and less liquid, and because these investments may be subject to increased economic, political, regulatory and other uncertainties.</li></ul><ul type = "square"><li>CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Fund's investments or reduce its returns.</li></ul><ul type = "square"><li>DIVERSIFICATION RISK: The Fund may have more risk because it is &#8220;non-diversified&#8221;, meaning that it can invest more of its assets in a smaller number of issuers and that adverse changes in the value of one security could have a more significant effect on the Fund's net asset value, or NAV.</li></ul><ul type = "square"><li>MANAGEMENT RISK: The Fund is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results.</li></ul>As with all investments, you may lose money by investing in the Fund.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 110% of the average value of its portfolio. The Fund invests, under normal circumstances, at least 80% of its net assets in fixed-income securities. The Fund expects to invest in readily marketable fixed-income securities with a range of maturities from short- to long-term and relatively attractive yields that do not involve undue risk of loss of capital. The Fund expects to invest in fixed-income securities with a dollar-weighted average maturity of between three to ten years and an average duration of three to six years. The Fund may invest up to 25% of its net assets in below investment grade bonds. The Fund may use leverage for investment purposes.<br/><br/>The Fund may invest without limit in U.S. Dollar-denominated foreign fixed-income securities and may invest up to 25% of its assets in non-U.S. Dollar-denominated foreign fixed-income securities. These investments may include, in each case, developed and emerging market debt securities.<br/><br/>The Adviser selects securities for purchase or sale based on its assessment of the securities' risk and return characteristics as well as the securities' impact on the overall risk and return characteristics of the Fund. In making this assessment, the Adviser takes into account various factors, including the credit quality and sensitivity to interest rates of the securities under consideration and of the Fund's other holdings.<br/><br/>The Fund may invest in mortgage-related and other asset-backed securities, loan participations, inflation-protected securities, structured securities, variable, floating, and inverse floating rate instruments and preferred stock, and may use other investment techniques. The Fund intends, among other things, to enter into transactions such as reverse repurchase agreements and dollar rolls. The Fund may invest, without limit, in derivatives, such as options, futures, forwards, or swaps. <ul type="square"><li>MARKET RISK: The value of the Fund's assets will fluctuate as the stock or bond market fluctuates.

Early payments of principal on some mortgage-related securities may occur during periods of falling mortgage interest rates and expose the Fund to a lower rate of return upon reinvestment of principal. Early payments associated with mortgage-related securities cause these securities to experience significantly greater price and yield volatility than is experienced by traditional fixed-income securities. During periods of rising interest rates, a reduction in prepayments may increase the effective life of mortgage-related securities, subjecting them to greater risk of decline in market value in response to rising interest rates.
