Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests in debt instruments, including securities rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”) and securities rated investment grade. The Fund may invest in securities rated below investment grade without limit. Below investment grade refers to ratings given by nationally recognized statistical rating organizations (e.g., rated Ba1 or below by Moody’s Ratings, or BB+ or below by S&P Global Ratings or Fitch Ratings, Inc.) or, if unrated, determined by the Fund to be of comparable quality. Below investment grade debt instruments are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. The Fund may also invest in floating rate loans and other floating rate debt instruments. The Fund is not managed relative to an index and instead seeks to produce positive returns across varying market conditions. To seek this goal, the Fund has flexibility to invest across a broad range of debt instruments and derivatives. The Fund generally maintains a dollar-weighted average duration profile between -2 and 6 years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. Debt instruments may include, without limitation, instruments issued by various U.S. and foreign (non-U.S.) (including those located in emerging market countries) public- or private-sector entities, bonds, debentures, notes, convertible securities, commercial paper, loans and related assignments and participations, corporate debt, asset- and mortgage-backed securities, preferred stock, bank certificates of deposit, fixed time deposits, bankers' acceptances and money market instruments, including money market funds denominated in U.S. dollars or foreign (non-U.S.) currencies. Floating rate loans and other floating rate debt instruments include floating rate bonds, floating rate notes, floating rate debentures, and tranches of floating rate asset-backed securities, including structured notes, made to, or issued by, U.S. and foreign (non-U.S.) corporations or other business entities. The Fund may also invest in inflation-indexed bonds of varying maturities issued by the U.S. and foreign (non-U.S.) governments, their agencies and instrumentalities, and U.S. and foreign (non-U.S.) corporations. The Fund may also invest in derivatives, including options, futures, swaps (including interest rate swaps, total return swaps, and credit default swaps), and currency forwards, as a substitute for taking a position in an underlying asset, to make tactical asset allocations, to seek to minimize risk, to enhance returns, and/or assist in managing cash. In evaluating investments for the Fund, the sub-adviser (the “Sub-Adviser”) takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance (“ESG”) factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing, when available. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser.The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.
