| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM? The municipal bond market has realized strong gains over the trailing one-year period. The market benefited from sharply lower yields, although much of the decrease occurred in the fourth quarter of 2023. More recently, the third quarter of 2024 was likewise a period of lower market yields, in response to lower inflation data. This led the U.S. Federal Reserve to cut its policy interest rate by 0.50% in September 2024. During the period, the market also benefited from strong demand, driven by greater investor interest due to lower inflation (higher real tax-equivalent yields), desire to access higher yields in the near term against an outlook of lower yields, and a potentially higher tax environment in 2025. Top contributors to the Fund’s performance relative to the Bloomberg 5-Year Municipal Bond Index: • Issue selection in total and particularly in local authority municipal bonds • Issue selection in state general obligation issues Top detractors to the Fund’s performance relative to the Bloomberg 5-Year Municipal Bond Index: • Interest rate sensitivity including both duration and yield curve effects • Sector allocation effect in total and, in particular, an underweight to gas forward issues | |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM? The municipal bond market has realized strong gains over the trailing one-year period. The market benefited from sharply lower yields, although much of the decrease occurred in the fourth quarter of 2023. More recently, the third quarter of 2024 was likewise a period of lower market yields, in response to lower inflation data. This led the U.S. Federal Reserve to cut its policy interest rate by 0.50% in September 2024. During the period, the market also benefited from strong demand, driven by greater investor interest due to lower inflation (higher real tax-equivalent yields), desire to access higher yields in the near term against an outlook of lower yields, and a potentially higher tax environment in 2025. Top contributors to the Fund’s performance relative to the Bloomberg Municipal 65% High Grade/35% High Yield Index: • Issue selection in municipal bonds within the higher education sector • Issue selection among municipal toll road issues Top detractors to the Fund’s performance relative to the Bloomberg Municipal 65% High Grade/35% High Yield Index: • Selection effect among local authority hospital, lifecare, and other revenue issues • Interest rate sensitivity including both duration and yield curve effects | |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM? Global bond markets were broadly, and strongly, positive for the trailing one-year period. During the period, central banks responded to lower inflation data and began to lower policy interest rates, which was favorable for bond prices and returns. Macroeconomic sentiment centered, particularly more recently, on a soft-landing scenario in the U.S., providing a supportive credit risk environment. During the period, narrowing credit spreads were a positive return driver in the global bond market, in addition to the response to lower bond market yields. This resulted in broad gains across varied market sectors, including government bonds, investment grade and high yield corporate securities, mortgage- and asset-backed instruments, and emerging market issues. Top contributors to the Fund’s performance relative to the Credit Suisse Leveraged Loan Index: • The Fund’s investment in U.S. bank loans contributed more than European loans • Despite the more recent fall in yields, coupon income was additive • Selection among B and CCC rated loans Top detractors to the Fund’s performance relative to the Credit Suisse Leveraged Loan Index: • The Fund’s allocation and selection among European bank loans as U.S. bank loans outperformed • Cash allocation as the asset class return was strong in the period | |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM? Global bond markets were broadly, and strongly, positive for the trailing one-year period. During the period, central banks responded to lower inflation data and began to lower policy interest rates, which was favorable for bond prices and returns. Macroeconomic sentiment centered, particularly more recently, on a soft-landing scenario in the U.S., providing a supportive credit risk environment. During the period, narrowing credit spreads were a positive return driver in the global bond market, in addition to the response to lower bond market yields. This resulted in broad gains across varied market sectors, including government bonds, investment grade and high yield corporate securities, mortgage- and asset-backed instruments, and emerging market issues. Top contributors to the Fund’s performance relative to the Credit Suisse Leveraged Loan Index: • The Fund’s investment in U.S. bank loans contributed more than European loans • Despite the more recent fall in yields, coupon income was additive • Selection among B and CCC rated loans Top detractors to the Fund’s performance relative to the Credit Suisse Leveraged Loan Index: • The Fund’s allocation and selection among European bank loans as U.S. bank loans outperformed • Cash allocation as the asset class return was strong in the period | |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM? Global bond markets were broadly, and strongly, positive for the trailing one-year period. During the period, central banks responded to lower inflation data and began to lower policy interest rates, which was favorable for bond prices and returns. Macroeconomic sentiment centered, particularly more recently, on a soft-landing scenario in the U.S., providing a supportive credit risk environment. During the period, narrowing credit spreads were a positive return driver in the global bond market, in addition to the response to lower bond market yields. This resulted in broad gains across varied market sectors, including government bonds, investment grade and high yield corporate securities, mortgage- and asset-backed instruments, and emerging market issues. Top contributors to the Fund’s performance relative to the Bloomberg Emerging Markets Hard Currency (USD) Aggregate Index: • The emerging market sovereign hard currency portfolio aided performance the most • The corporate portfolio particularly Mexican companies was favorable Top detractors to the Fund’s performance relative to the Bloomberg Emerging Markets Hard Currency (USD) Aggregate Index: • Local rates exposure • Various currency exposures as part of the foreign exchange hedging strategy | |
