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’s relative performance was positively impacted by security selection in the Building Materials, Packaging, Midstream, Chemicals and Retailers industry sectors.

  • Bullet

    The Fund was positively impacted by its underweight allocations to the underperforming Retailers and Midstream industry sectors. The Fund’s opportunistic equity allocation also contributed to relative performance.

  • Bullet

    Specific Fund holdings that positively impacted performance relative to the Index included CSC Holdings, Foundation Building Materials, Dornoch Debt Merger Sub and Trivium Packaging.

Top Detractors from Performance

  • Bullet

    The Fund’s relative performance was negatively impacted by security selection in the Property & Casualty and Cable & Satellite industry sectors.

  • Bullet

    The Fund was negatively impacted by its underweight allocations to the strong performing Media & Entertainment and Wirelines industry sectors. Relative performance was also negatively impacted by its overweight allocation to the underperforming Technology and Packaging industry sectors. The Fund’s cash position also detracted from performance 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 McAfee Corp, Rocket Software, Warner Bros Discovery and Cvent.

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.

Factors Affecting Performance [Text Block]

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’s relative performance was positively impacted by security selection in the Building Materials, Packaging, Midstream, Chemicals and Retailers industry sectors.

  • Bullet

    The Fund was positively impacted by its underweight allocations to the underperforming Retailers and Midstream industry sectors. The Fund’s opportunistic equity allocation also contributed to relative performance.

  • Bullet

    Specific Fund holdings that positively impacted performance relative to the Index included CSC Holdings, Foundation Building Materials, Dornoch Debt Merger Sub and Trivium Packaging.

Top Detractors from Performance

  • Bullet

    The Fund’s relative performance was negatively impacted by security selection in the Property & Casualty and Cable & Satellite industry sectors.

  • Bullet

    The Fund was negatively impacted by its underweight allocations to the strong performing Media & Entertainment and Wirelines industry sectors. Relative performance was also negatively impacted by its overweight allocation to the underperforming Technology and Packaging industry sectors. The Fund’s cash position also detracted from performance 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 McAfee Corp, Rocket Software, Warner Bros Discovery and Cvent.

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.
