How did the Fund perform during the reporting period and what affected its performance?

Exposure to securitized assets, including collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened.

Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

The structural allocation to short-term U.S. Treasury inflation-protected securities ("TIPS”), contributed to relative performance versus the Bloomberg Commodity Index Total Return ("Index"), as short-term TIPS underperformed 3-month Treasury Bills.
Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Index, as eurozone rates rose, while swaps spreads tightened.
Positioning within the agriculture sector, including an underweight exposure to corn, contributed to relative performance versus the Index, as corn posted negative returns.
Exposure to U.S. non-agency residential mortgage-backed securities and collateralized loan obligations contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.
Positioning within the energy sector, including an underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

The structural allocation to short-term U.S. Treasury inflation-protected securities ("TIPS”), contributed to relative performance versus the Bloomberg Commodity Index Total Return ("Index"), as short-term TIPS underperformed 3-month Treasury Bills.
Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Index, as eurozone rates rose, while swaps spreads tightened.
Positioning within the agriculture sector, including an underweight exposure to corn, contributed to relative performance versus the Index, as corn posted negative returns.
Exposure to U.S. non-agency residential mortgage-backed securities and collateralized loan obligations contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.
Positioning within the energy sector, including an underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

The structural allocation to short-term U.S. Treasury inflation-protected securities ("TIPS”), contributed to relative performance versus the Bloomberg Commodity Index Total Return ("Index"), as short-term TIPS underperformed 3-month Treasury Bills.
Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Index, as eurozone rates rose, while swaps spreads tightened.
Positioning within the agriculture sector, including an underweight exposure to corn, contributed to relative performance versus the Index, as corn posted negative returns.
Exposure to U.S. non-agency residential mortgage-backed securities and collateralized loan obligations contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.
Positioning within the energy sector, including an underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

The structural allocation to short-term U.S. Treasury inflation-protected securities ("TIPS”), contributed to relative performance versus the Bloomberg Commodity Index Total Return ("Index"), as short-term TIPS underperformed 3-month Treasury Bills.
Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Index, as eurozone rates rose, while swaps spreads tightened.
Positioning within the agriculture sector, including an underweight exposure to corn, contributed to relative performance versus the Index, as corn posted negative returns.
Exposure to U.S. non-agency residential mortgage-backed securities and collateralized loan obligations contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.
Positioning within the energy sector, including an underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

The structural allocation to short-term U.S. Treasury inflation-protected securities ("TIPS”), contributed to relative performance versus the Bloomberg Commodity Index Total Return ("Index"), as short-term TIPS underperformed 3-month Treasury Bills.
Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Index, as eurozone rates rose, while swaps spreads tightened.
Positioning within the agriculture sector, including an underweight exposure to corn, contributed to relative performance versus the Index, as corn posted negative returns.
Exposure to U.S. non-agency residential mortgage-backed securities and collateralized loan obligations contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.
Positioning within the energy sector, including an underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

The structural allocation to short-term U.S. Treasury inflation-protected securities ("TIPS”), contributed to relative performance versus the Bloomberg Commodity Index Total Return ("Index"), as short-term TIPS underperformed 3-month Treasury Bills.
Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Index, as eurozone rates rose, while swaps spreads tightened.
Positioning within the agriculture sector, including an underweight exposure to corn, contributed to relative performance versus the Index, as corn posted negative returns.
Exposure to U.S. non-agency residential mortgage-backed securities and collateralized loan obligations contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance versus the Index, as CCAs posted negative returns.
Positioning within the energy sector, including an underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Supplemental Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance, as CCAs posted negative returns. Positioning within the energy sector, including underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
Active real estate investment trust ("REIT") strategies, including underweight exposure to healthcare REITs, detracted from relative performance versus the Index, as healthcare REITs posted positive returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Supplemental Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance, as CCAs posted negative returns. Positioning within the energy sector, including underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
Active real estate investment trust ("REIT") strategies, including underweight exposure to healthcare REITs, detracted from relative performance versus the Index, as healthcare REITs posted positive returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Supplemental Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to California Carbon Allowances ("CCAs") detracted from relative performance, as CCAs posted negative returns. Positioning within the energy sector, including underweight exposure to natural gas, detracted from relative performance versus the Index, as natural gas posted positive returns.
Active real estate investment trust ("REIT") strategies, including underweight exposure to healthcare REITs, detracted from relative performance versus the Index, as healthcare REITs posted positive returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. Treasury Inflation Notes: 10+ Year Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
Exposure to securitized assets, including U.S. non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Long exposure to U.K. interest rates detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. Treasury Inflation Notes: 10+ Year Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
Exposure to securitized assets, including U.S. non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Long exposure to U.K. interest rates detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Overweight exposure to U.S. duration, specifically the 2-year part of the curve, contributed to relative performance versus the ICE BofA 1-3 Year U.S. Treasury Index ("Index"), as interest rates fell.
Overweight commercial mortgage-backed securities ("MBS") contributed to relative performance versus the Index, as short term commercial MBS had positive return.
Overweight exposure to investment grade corporate credit, specifically financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive returns.
Long exposure to U.K. duration, particularly on the 5-year part of the curve, detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Overweight exposure to U.S. duration, specifically the 2-year part of the curve, contributed to relative performance versus the ICE BofA 1-3 Year U.S. Treasury Index ("Index"), as interest rates fell.
Overweight commercial mortgage-backed securities ("MBS") contributed to relative performance versus the Index, as short term commercial MBS had positive return.
Overweight exposure to investment grade corporate credit, specifically financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive returns.
Long exposure to U.K. duration, particularly on the 5-year part of the curve, detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Overweight exposure to U.S. duration, specifically the 2-year part of the curve, contributed to relative performance versus the ICE BofA 1-3 Year U.S. Treasury Index ("Index"), as interest rates fell.
Overweight exposure to agency mortgage-backed securities contributed to relative performance versus the Index, as spreads tightened.
Overweight exposure to select securitized credit, particularly collateralized loan obligations, contributed to relative performance versus the Index, as spreads tightened.
Long exposure to U.K. duration, particularly on the 5-year part of the curve, detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Overweight exposure to U.S. duration, specifically the 2-year part of the curve, contributed to relative performance versus the ICE BofA 1-3 Year U.S. Treasury Index ("Index"), as interest rates fell.
Overweight exposure to agency mortgage-backed securities contributed to relative performance versus the Index, as spreads tightened.
Overweight exposure to select securitized credit, particularly collateralized loan obligations, contributed to relative performance versus the Index, as spreads tightened.
Long exposure to U.K. duration, particularly on the 5-year part of the curve, detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Overweight exposure to U.S. duration, specifically the 2-year part of the curve, contributed to relative performance versus the ICE BofA 1-3 Year U.S. Treasury Index ("Index"), as interest rates fell.
Overweight exposure to agency mortgage-backed securities contributed to relative performance versus the Index, as spreads tightened.
Overweight exposure to select securitized credit, particularly collateralized loan obligations, contributed to relative performance versus the Index, as spreads tightened.
Long exposure to U.K. duration, particularly on the 5-year part of the curve, detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Overweight exposure to U.S. duration, specifically the 2-year part of the curve, contributed to relative performance versus the ICE BofA 1-3 Year U.S. Treasury Index ("Index"), as interest rates fell.
Overweight exposure to agency mortgage-backed securities contributed to relative performance versus the Index, as spreads tightened.
Overweight exposure to select securitized credit, particularly collateralized loan obligations, contributed to relative performance versus the Index, as spreads tightened.
Long exposure to U.K. duration, particularly on the 5-year part of the curve, detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. TIPS Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Long exposure to U.K. duration detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. TIPS Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Long exposure to U.K. duration detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. TIPS Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Long exposure to U.K. duration detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. TIPS Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Long exposure to U.K. duration detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. TIPS Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Long exposure to U.K. duration detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Bloomberg U.S. TIPS Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
U.S. yield curve positioning, specifically overweight exposure to intermediate maturities relative to underweight exposure to long-term maturities, contributed to relative performance versus the Index, as the U.S. yield curve steepened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Long exposure to U.K. duration detracted from relative performance versus the Index, as U.K. interest rates broadly moved higher.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Dow Jones U.S. Select REIT Total Return Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including U.S. non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Underweight exposure to healthcare real estate investment trusts ("REITs") detracted from relative performance versus the Index, as healthcare REITs posted positive returns.
Underweight exposure to data center REITs detracted from relative performance versus the Index, as data center REITs delivered positive returns.
Underweight exposure to office REITs detracted from relative performance versus the Index, as office REITs delivered positive returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Dow Jones U.S. Select REIT Total Return Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including U.S. non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Underweight exposure to healthcare real estate investment trusts ("REITs") detracted from relative performance versus the Index, as healthcare REITs posted positive returns.
Underweight exposure to data center REITs detracted from relative performance versus the Index, as data center REITs delivered positive returns.
Underweight exposure to office REITs detracted from relative performance versus the Index, as office REITs delivered positive returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Eurozone interest rate strategies, including short exposure to duration and exposure to swap spreads, contributed to relative performance versus the Dow Jones U.S. Select REIT Total Return Index ("Index"), as eurozone rates rose, while swaps spreads tightened.
Overweight exposure to intermediate U.S. breakeven inflation contributed to relative performance versus the Index, as intermediate U.S. breakeven inflation rose.
Exposure to securitized assets, including U.S. non-agency residential mortgage-backed securities and collateralized loan obligations, contributed to relative performance versus the Index, as spreads broadly tightened across these sectors.
Underweight exposure to healthcare real estate investment trusts ("REITs") detracted from relative performance versus the Index, as healthcare REITs posted positive returns.
Underweight exposure to data center REITs detracted from relative performance versus the Index, as data center REITs delivered positive returns.
Underweight exposure to office REITs detracted from relative performance versus the Index, as office REITs delivered positive returns.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as investment grade corporate bonds had positive total returns.
Select holdings of securitized credit, particularly asset-backed securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the Index, as carry contributions from ABS offset detractions from spreads widening and CLO spreads tightened.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
There were no material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as investment grade corporate bonds had positive total returns.
Select holdings of securitized credit, particularly asset-backed securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the Index, as carry contributions from ABS offset detractions from spreads widening and CLO spreads tightened.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
There were no material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as investment grade corporate bonds had positive total returns.
Select holdings of securitized credit, particularly asset-backed securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the Index, as carry contributions from ABS offset detractions from spreads widening and CLO spreads tightened.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
There were no material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as investment grade corporate bonds had positive total returns.
Select holdings of securitized credit, particularly asset-backed securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the Index, as carry contributions from ABS offset detractions from spreads widening and CLO spreads tightened.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as investment grade corporate bonds had positive total returns.
Select holdings of securitized credit, particularly asset-backed securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the Index, as carry contributions from ABS offset detractions from spreads widening and CLO spreads tightened.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
There were no material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Select holdings of securitized credit, particularly asset-based securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as coupon payments on ABS investments offset spread widening, and CLO spreads tightened.
Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive total returns.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
Overweight exposure to U.K. duration in the 5-year part of the curve detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Select holdings of securitized credit, particularly asset-based securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as coupon payments on ABS investments offset spread widening, and CLO spreads tightened.
Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive total returns.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
Overweight exposure to U.K. duration in the 5-year part of the curve detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Performance Past Does Not Indicate Future [Text]

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Select holdings of securitized credit, particularly asset-based securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as coupon payments on ABS investments offset spread widening, and CLO spreads tightened.
Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive total returns.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
Overweight exposure to U.K. duration in the 5-year part of the curve detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Select holdings of securitized credit, particularly asset-based securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as coupon payments on ABS investments offset spread widening, and CLO spreads tightened.
Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive total returns.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
Overweight exposure to U.K. duration in the 5-year part of the curve detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Select holdings of securitized credit, particularly asset-based securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as coupon payments on ABS investments offset spread widening, and CLO spreads tightened.
Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive total returns.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
Overweight exposure to U.K. duration in the 5-year part of the curve detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period and what affected its performance?

The following affected performance (on a gross basis) during the reporting period:

Select holdings of securitized credit, particularly asset-based securities (“ABS”) and collateralized loan obligations (“CLO”) contributed to relative performance versus the FTSE 3-Month Treasury Bill Index ("Index"), as coupon payments on ABS investments offset spread widening, and CLO spreads tightened.
Holdings of investment grade corporate credit, particularly financials, contributed to relative performance versus the Index, as investment grade corporate bonds had positive total returns.
Overweight exposure to U.S. duration in the 1-year part of the curve contributed to relative performance versus the Index, as interest rates fell.
Overweight exposure to U.K. duration in the 5-year part of the curve detracted from relative performance versus the Index, as interest rates rose.
There were no other material detractors for this Fund.
