Management's Discussion of Fund Performance

The following discussion compares the performance of the Fund to the Bloomberg US Corporate High Yield 2% Issuer Capped Index (the “Index”) to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes including the Bloomberg US Aggregate Bond Index, which represents the overall U.S. fixed-income market. The Fund seeks high current income by investing primarily in a professionally managed, diversified portfolio of fixed-income securities rated below investment grade.

 

Top Contributors to Performance

  • Bullet

    The Fund was positively impacted by security selection in the Insurance-P&C, Consumer Cyclical Services, Healthcare, Diversified Manufacturing and Building Materials industry sectors.

  • Bullet

    The Fund was positively impacted by its underweight allocation to the underperforming Wireless and Metals & Mining sectors as well as its overweight allocation to the outperforming Technology sector.

  • Bullet

    Specific Fund holdings that positively impacted performance relative to the Index included: SRS Distribution, McAfee Corp., Allied Universal Holdco, Clydesdale Acquisition, AthenaHealth Group and Rocket Software.

 

Top Detractors from Performance

  • Bullet

    The Fund was negatively impacted by security selection in the Media & Entertainment, Packaging, Electric, Technology and Auto industry sectors.

  • Bullet

    The Fund was negatively impacted by its industry allocation, especially its underweight position in the strong performing Wireline Telecommunication sector. It was also negatively impacted by its overweight allocation to the underperforming Packaging and Auto sectors. The Fund’s opportunistic equity allocation also detracted from performance, as did the Fund’s cash position given the strong absolute performance of high yield bonds during the period.

  • Bullet

    Specific Fund holdings that negatively impacted performance relative to the Index included: iHeartCommunications, Ardagh Packaging, Enviva Inc., CSC Holdings LLC and Dornoch Debt Merger Sub.

Performance Past Does Not Indicate Future [Text] Keep in mind that the Fund’s past performance is not a good predictor of how the Fund will perform in the future.
