The Fund invests primarily in below investment-grade bonds of corporate issuers. These bonds may pay interest on a semiannual basis (i.e. cash pay bonds) or have a deferred interest feature (i.e. zero coupon bonds). The Fund also may invest in private placements. Only U.S. dollar denominated securities are considered for investment in the Fund.
The Subadviser selects securities using its internally developed proprietary tools. The Subadviser seeks to select securities issued by companies that generally exhibit, or are believed to have the prospect for, positive credit momentum with the potential for credit rating upgrade. The Subadviser seeks to maximize portfolio return and minimize default risk by adhering to the following elements of its philosophy:
The Subadviser conducts an in-depth analysis using proprietary research tools in addition to communicating with management of the issuers to select securities for investment in the Fund and to monitor the selected securities on a systematic basis. All securities in the portfolio are reviewed at least four times a year. As part of the selection and monitoring process, the Subadviser actively seeks to avoid holding securities of issuers that it deems to have a high risk of default.
Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in a diversified portfolio of below investment-grade, high-risk, corporate bonds that are rated below Baa3 by Moody's or below BBB- by S&P or Fitch, commonly referred to as "high-yield" or "junk bonds."
The Fund may invest up to 20% of its net assets in bank loans and up to 10% of its total assets in equity securities, including common stock. Additionally, the Fund may invest a portion of its assets in credit default swaps and bank loans to corporate issuers.
Duration/Maturity. Although duration may be one of the characteristics considered in security selection, the Fund does not focus on bonds with any particular duration or maturity and does not seek to maintain the maturity of the Fund's portfolio in any particular range. The weighted average maturity of the Fund's portfolio was 6.82 years as of December 31, 2012.
Credit Quality. The Fund invests primarily in below investment-grade debt securities, commonly referred to as "high-yield" or "junk" bonds, but may invest up to 20% of its net assets in investment-grade securities, including U.S. Treasury and U.S. government agency securities. As such, the Fund's average weighted portfolio quality varies from time to time, depending on the level of assets allocated to such securities. The Subadviser does not seek to actively invest in defaulted securities.
Interest rate risk: As interest rates rise, the values of fixed income securities held by the Fund are likely to decrease and reduce the value of the Fund's portfolio. Securities with longer durations tend to be more sensitive to changes in interest rates and are usually more volatile than securities with shorter durations. For example, a 5 year average duration generally means the fixed income security will decrease in value by 5% if interest rates rise by 1%. Interest rates in the U.S. are at, or near, historic lows, which may increase the Fund's exposure to risks associated with rising rates.
Credit risk: The issuer of a security owned by the Fund could default on its obligation to pay principal or interest or its credit rating could be downgraded. Likewise, a counterparty to a derivative or other contractual instrument owned by the Fund could default on its obligation. Credit risk is higher for the Fund because it invests primarily in below investmentgrade securities.
Market and Issuer risk: Securities markets are volatile and can decline significantly in response to adverse market, economic, political or regulatory developments, which may increase the risk that issuers will not generate sufficient cash flow to service their debt obligations.
High-yield risk: There is a greater risk that the Fund will lose money because it invests primarily in high-yield bonds. These securities are considered speculative because they have a higher risk of issuer default, are subject to greater price volatility and may be illiquid.
Prepayment risk: When interest rates are declining, the issuer of a pass-through security, such as a mortgage-backed or an asset-backed security, may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities.
Selection risk: The Subadviser's judgment about the attractiveness, value and potential appreciation of a particular security may be incorrect.
Liquidity risk: The market for high-yield bonds is less liquid than the market for investment-grade bonds. The Fund may at times have greater difficulty buying or selling specific high-yield bonds at prices the Subadviser believes are reasonable, which would be adverse to the Fund.
