| Factors Affecting Performance [Text Block] | How Did the Fund Perform Last Year? What Affected the Fund's Performance? Over the 12-month period, all share classes outperformed the Bloomberg Global Aggregate Bond Index (the "benchmark”). Security selection added the most to relative outperformance, mainly due to selections in US asset-backed securities, investment-grade corporate bonds, US agency mortgage-backed securities and US commercial mortgage-backed securities. Sector allocation also contributed, namely off-benchmark exposure to agency risk sharing securities and an underweight to US Treasuries, which offset losses from an underweight to US investment-grade corporates and off-benchmark positioning in US inflation-linked securities. Yield-curve positioning also contributed to results, mainly from an overweight to the six-month part of the US curve and an underweight to the 30-year part of the US curve, partially offset by losses from overweights to the two- and 20-year parts of the curve. Country allocation and currency decisions were minor detractors to performance. During the 12-month period, the Fund used derivatives in the form of interest rate futures to manage and hedge duration risk and/or take active yield-curve positioning. Currency forwards were used to hedge foreign currency exposure and to take active currency risk. Credit default swaps were also utilized to effectively obtain high-yield credit/sector exposure. Total return swaps were used to create synthetic high-yield exposure in the Fund. Purchased options and written options were utilized as part of put spread for downside protection. |

Sector allocation also contributed, namely off-benchmark exposure to agency risk sharing securities and an underweight to US Treasuries, which offset losses from an underweight to US investment-grade corporates and off-benchmark positioning in US inflation-linked securities. Yield-curve positioning also contributed to results, mainly from an overweight to the six-month part of the US curve and an underweight to the 30-year part of the US curve, partially offset by losses from overweights to the two- and 20-year parts of the curve. Country allocation and currency decisions were minor detractors to performance. During the 12-month period, the Fund used derivatives in the form of interest rate futures to manage and hedge duration risk and/or take active yield-curve positioning. Currency forwards were used to hedge foreign currency exposure and to take active currency risk. Credit default swaps were also utilized to effectively obtain high-yield credit/sector exposure. Total return swaps were used to create synthetic high-yield exposure in the Fund. Purchased options and written options were utilized as part of put spread for downside protection. |
