Factors Affecting Performance [Text Block]
How did the Fund perform last year?
  For the 12 month period ended July 31, 2025, the Fund’s Class A shares returned 10.81%.
  In comparison, the S&P High Yield Dividend Aristocrats Index (the "Benchmark") returned 4.55% for the same period.
     
What affected the Fund’s performance?
  The Federal Reserve (“the Fed”) reduced rates by 0.50% in September 2024, 0.25% in November 2024, and 0.25% in December 2024 to bring the Federal Funds Rate to 4.25-4.50%.
  U.S. stocks rose sharply over the period, despite having a correction in April due to tariff announcements. Performance was driven by optimism on artificial intelligence and on hopes that the Fed would cut rates in the latter half of 2025.
  Technology and communication services were the best performing sectors, while health care and energy performed the worst.
  The Fund outperformed the Benchmark, primarily driven by stock selection in technology, financials, and consumer staples.
  Detracting from relative performance was stock selection in health care.

Factors Affecting Performance [Text Block]
How did the Fund perform last year?
  For the 12 month period ended July 31, 2025, the Fund’s Class A shares returned 13.80%.
  In comparison, the S&P 500 Total Return Index (the "Benchmark") returned 16.33% for the same period.
     
What affected the Fund’s performance?
  The Federal Reserve (“the Fed”) reduced rates by 0.50% in September 2024, 0.25% in November 2024, and 0.25% in December 2024 to bring the Federal Funds Rate to 4.25-4.50%.
  U.S. stocks rose sharply over the period, despite having a correction in April 2025 due to tariff announcements. Performance was driven by optimism on artificial intelligence and on hopes that the Fed would cut rates in the latter half of 2025.
  Technology and communication services were the best performing sectors, while health care and energy performed the worst.
  The Fund underperformed the Benchmark, primarily driven by stock selection in consumer staples and health care.
  Aiding relative performance over the period was an underweight allocation to health care and an overweight allocation to technology.

How did the Fund perform last year?
  For the 12 month period ended July 31, 2025, the Fund's Class A shares returned 8.42%.
  In comparison, the Bloomberg U.S. Corporate High Yield Bond Index (the "Benchmark") returned 8.67% for the same period.
     
What affected the Fund’s performance?
  During the period, the Fund's overweight position in the Cable Satellite sector, along with the Fund's security selection in Pharmaceuticals and Midstream, contributed to relative performance. Conversely, the Fund's security selection in Retailers, overweight position in Automotive and underweight position in Wireless detracted from relative performance.
  Compared to the Benchmark on July 31, 2025, the Fund was overweight in the Cable Satellite, Automotive and Independent Energy sectors due to the relative value opportunities within those sectors. The Fund was underweight in Finance Companies, P&C and Retailers because the portfolio managers did not find these sectors attractive due to challenging fundamental outlooks or rich valuations. Relative to the Benchmark on July 31, 2025, the Fund’s yield, spread and duration were lower than those of the Benchmark.
  Specifically, the Fund's overweight positions in Lumen Technologies, Bausch Health, DISH Network and Intelsat paired with lack of exposure to New Fortress Energy contributed to relative performance. Overweight positions in Claires, Rite Aid and Ford Motor Company, lack of exposure to Uniti Group and the Fund's underweight position in CSC Holdings were the top detractors in the period.

  Specifically, the Fund's overweight positions in Lumen Technologies, Bausch Health, DISH Network and Intelsat paired with lack of exposure to New Fortress Energy contributed to relative performance. Overweight positions in Claires, Rite Aid and Ford Motor Company, lack of exposure to Uniti Group and the Fund's underweight position in CSC Holdings were the top detractors in the period.

Factors Affecting Performance [Text Block]
How did the Fund perform last year?
  For the 12 month period ended July 31, 2025, the Fund's Class I shares returned 8.84%.
  In comparison, the Bloomberg U.S. Corporate High Yield Bond Index (the "Benchmark") returned 8.67% for the same period.
     
What affected the Fund’s performance?
  During the period, the Fund's overweight position in the Cable Satellite sector, along with the Fund's security selection in Pharmaceuticals and Midstream, contributed to relative performance. Conversely, the Fund's security selection in Retailers, overweight position in Automotive and underweight position in Wireless detracted from relative performance.
  Compared to the Benchmark on July 31, 2025, the Fund was overweight in the Cable Satellite, Automotive and Independent Energy sectors due to the relative value opportunities within those sectors. The Fund was underweight in Finance Companies, P&C and Retailers because the portfolio managers did not find these sectors attractive due to challenging fundamental outlooks or rich valuations. Relative to the Benchmark on July 31, 2025, the Fund’s yield, spread and duration were lower than those of the Benchmark.
  Specifically, the Fund's overweight positions in Lumen Technologies, Bausch Health, DISH Network and Intelsat paired with lack of exposure to New Fortress Energy contributed to relative performance. Overweight positions in Claires, Rite Aid and Ford Motor Company, lack of exposure to Uniti Group and the Fund's underweight position in CSC Holdings were the top detractors in the period.

How did the Fund perform last year?
  For the 12 month period ended July 31, 2025, the Fund’s Class A shares returned 13.89%.
  In comparison, the S&P 1500 Energy Total Return Index (the "Benchmark") returned -3.84% for the same period.
     
What affected the Fund’s performance?
  The Federal Reserve (“the Fed”) reduced rates by 0.50% in September 2024, 0.25% in November 2024, and 0.25% in December 2024 to bring the Federal Funds Rate to 4.25-4.50%.
  U.S. stocks rose sharply over the period, despite having a correction in April 2025 due to tariff announcements. Performance was driven by optimism on artificial intelligence and on hopes that the Fed would cut rates in the latter half of 2025.
  Crude oil prices experienced elevated volatility over the period as geopolitical tensions were offset by an oversupplied market. Crude oil traded modestly lower for the period.
  Aiding relative performance versus the Benchmark over the period was an overweight allocation to utilities, independent power producer and midstream, as well as stock selection in exploration & production.
  Detracting from relative performance was an overweight allocation to oilfield service.
Return of Capital Distribution
As of July 31, 2025 distributable earnings was increased and paid in capital was decreased in the amount of $0.01 per share due to distributions paid in excess of earnings for class A.

  In comparison, the ICE BofA 1-3 Year US Treasury Index (the "Benchmark") returned 4.43% for the same period.
     
What affected the Fund’s performance?
  Fixed income sectors in general benefited from the regime change in the Federal Reserve ("the Fed") policy, as the Federal Open Market Committee reduced the fed funds rates by 1% to 4.375%. The Treasury yield curve steepened significantly with short and intermediate-maturity Treasury yields declining given market uncertainty over the economic drag from trade policy under the new administration, while debt sustainability concerns raised longer maturity Treasury yields. As a result, the Fund’s short duration contributed to the outperformance. In addition, the portfolio’s weighting in certain Ginnie Mae mortgage-backed securities sectors and security selection further contributed to performance.
  The spread of agency mortgage-backed securities over Treasuries tightened moderately during the 12 month period. A higher overall yield relative to that of the pre-COVID era also improved the income return of the Fund. In addition, steady cashflow patterns of short duration Agency mortgage-backed securities backed by seasoned loans with historically low mortgage rates contributed meaningfully to performance. Lastly, yield curve reshaping positively impacted returns as 2-year Treasury yields decreased by 30 basis points over the 12 month period, while the 10-year Treasury yields was higher by 34bps.
  The fund continues to be overweight in Agency mortgage-backed securities relative to Treasuries and, more specifically, Ginnie Mae Project Loan mortgage-backed securities. Also, the Fund has a moderately longer duration than the Benchmark which should be a benefit if short maturity Treasury yields decline.
  Income and positive price return contributed about two-thirds and one-third, respectively, of the total return over the 12 month period. The Fund yield also exceeded that of the Benchmark over the 12 month period.
