| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Global concerns around heightened inflation, changes in central bank policies, geopolitical risks in the Middle East and a stronger US Dollar were primary drivers of Fund performance during the reporting period. The year 2024 saw a number of global central banks begin easing after keeping rates high to combat sticky inflation in 2023. However, the path to easing was anything but smooth, as growth and other economic data generally remained strong, and as such the speed and magnitude of policy easing was pared back for many central banks, particularly in the US. This led to substantial volatility within international bond markets as investors contended with uncertainty of the future path of interest rates. Risk appetite was further impacted by uncertainty surrounding the incoming US President’s policies regarding taxes, energy, trade, and regulatory policies and how they would impact broader global markets. In addition, a surge in the US dollar in the fourth quarter caused a negative drag on local currency returns. The Fund uses forwards to manage currency exposure, particularly when there are flows around month end, and for currency exposure purposes during market holidays and in the event of challenging liquidity in bond markets. |
| Performance Past Does Not Indicate Future [Text] | The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future. The returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or on the redemption or sale of Fund shares. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Global concerns around heightened inflation and changes in central bank policies were primary drivers of Fund performance during the reporting period. The Fund performed in line with expectations. The year 2024 saw a number of global central banks begin easing after keeping rates high to combat sticky inflation in 2023. The European Central Bank and the U.S. Federal Reserve both cut rates by 100 basis points in 2024, while the Bank of England kept cuts to 50 basis points. However the path to easing was anything but smooth, as growth and other economic data generally remained strong, and as such the speed and magnitude of policy easing was pared back for many central banks, particularly in the U.S.. This led to substantial volatility within the international bond market as investors contended with uncertainty of the future path of interest rates. All major government bond yields ended the year higher which negatively impacted spread sectors such as global corporates. Uncertainty around the incoming U.S. President’s policies regarding tariffs and their potential impacts on the international backdrop have forced investors to exercise caution in this sector. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Global concerns around heightened inflation and changes in central bank policies were primary drivers of Fund performance during the reporting period. The Fund performed in line with expectations. The year 2024 saw a number of global central banks begin easing after keeping rates high to combat sticky inflation in 2023. The European Central Bank and the U.S. Federal Reserve both cut rates by 100 basis points in 2024, while the Bank of England kept cuts to 50 basis points. However the path to easing was anything but smooth, as growth and other economic data generally remained strong, and as such the speed and magnitude of policy easing was pared back for many central banks, particularly in the U.S.. This led to substantial volatility within the international government bond sector as investors contended with uncertainty of the future path of interest rates. All major government bond yields ended the year higher than where they started, resulting in negative performance for global Treasuries. Uncertainty around the incoming U.S. President’s policies regarding tariffs and their potential impacts on the international backdrop have forced investors to exercise caution in this sector. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Global concerns around heightened inflation and changes in central bank policies were primary drivers of Fund performance during the reporting period. The Fund performed in line with expectations. The year 2024 saw a number of global central banks begin easing after keeping rates high to combat sticky inflation in 2023. The European Central Bank and the U.S. Federal Reserve both cut rates by 100 basis points in 2024, while the Bank of England kept cuts to 50 basis points. However the path to easing was anything but smooth, as growth and other economic data generally remained strong, and as such the speed and magnitude of policy easing was pared back for many central banks, particularly in the U.S.. This led to substantial volatility within the international government bond sector as investors contended with uncertainty of the future path of interest rates. All major government bond yields ended the year higher than where they started, resulting in negative performance for global Treasuries. Uncertainty around the incoming U.S. President’s policies regarding tariffs and their potential impacts on the international backdrop have forced investors to exercise caution in this sector. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Global concerns around heightened inflation and changes in central bank policies were primary drivers of Fund performance during the reporting period. The Fund performed in line with expectations. The year 2024 saw a number of global central banks begin easing after keeping rates high to combat sticky inflation in 2023. The European Central Bank and the U.S. Federal Reserve both cut rates by 100 basis points in 2024, while the Bank of England kept cuts to 50 basis points. However the path to easing was anything but smooth, as growth and other economic data generally remained strong, and as such the speed and magnitude of policy easing was pared back for many central banks, particularly in the U.S.. This led to substantial volatility within the international government bond sector as investors contended with uncertainty of the future path of interest rates. All major government bond yields ended the year higher than where they started, resulting in negative performance for global Treasuries. Uncertainty around the incoming U.S. President’s policies regarding tariffs and their potential impacts on the international backdrop have forced investors to exercise caution in this sector. |
