Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Equity markets advanced as expectations for a soft landing in the U.S. economy grew. The Russell 1000^® Index posted an approximately 38% return, with U.S. mid cap and small cap equities delivering gains of approximately 35% and 34%, respectively. In comparison, emerging markets and developed markets outside the U.S. generated relatively lower returns of 25% and 23%, respectively. In fixed income markets, the Fed implemented a 50 basis point rate cut in September, coinciding with a decline in inflation. This environment favored longer-duration fixed income assets, which outperformed their shorter-duration counterparts. Credit spreads remained tight, reflecting the continued expectation of a soft landing in the U.S.

The Fund outperformed its primary benchmark for the fiscal year. The Fund’s strategic asset allocation positioning maintained a slight overweight to key risk factors, including equity beta (volatility in relation to the overall market), which contributed positively. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Equity markets advanced as expectations for a soft landing in the U.S. economy grew. The Russell 1000^® Index posted an approximately 38% return, with U.S. mid cap and small cap equities delivering gains of approximately 35% and 34%, respectively. In comparison, emerging markets and developed markets outside the U.S. generated relatively lower returns of 25% and 23%, respectively. In fixed income markets, the Fed implemented a 50 basis point rate cut in September, coinciding with a decline in inflation. This environment favored longer-duration fixed income assets, which outperformed their shorter-duration counterparts. Credit spreads remained tight, reflecting the continued expectation of a soft landing in the U.S.

The Fund outperformed its primary benchmark for the fiscal year. The Fund’s strategic asset allocation positioning maintained a slight overweight to key risk factors, including equity beta (volatility in relation to the overall market), which contributed positively. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Equity markets advanced as expectations for a soft landing in the U.S. economy grew. The Russell 1000^® Index posted an approximately 38% return, with U.S. mid cap and small cap equities delivering gains of approximately 35% and 34%, respectively. In comparison, emerging markets and developed markets outside the U.S. generated relatively lower returns of approximately 25% and 24%, respectively. In fixed income markets, the Fed implemented a 50 basis point rate cut in September, coinciding with a decline in inflation. This environment favored longer-duration fixed income assets, which outperformed their shorter-duration counterparts. Credit spreads remained tight, reflecting the continued expectation of a soft landing in the U.S.

The Fund underperformed its primary benchmark for the fiscal year, primarily due to the detractive impact of its diversification across asset classes. The Fund’s strategic asset allocation positioning maintained exposures to key risk factors, including duration and credit exposure, to enable portfolio diversification. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Equity markets advanced as expectations for a soft landing in the U.S. economy grew. The Russell 1000^® Index posted an approximately 38% return, with U.S. mid cap and small cap equities delivering gains of approximately 35% and 34%, respectively. In comparison, emerging markets and developed markets outside the U.S. generated relatively lower returns of approximately 25% and 24%, respectively. In fixed income markets, the Fed implemented a 50 basis point rate cut in September, coinciding with a decline in inflation. This environment favored longer-duration fixed income assets, which outperformed their shorter-duration counterparts. Credit spreads remained tight, reflecting the continued expectation of a soft landing in the U.S.

The Fund underperformed its primary benchmark for the fiscal year, primarily due to the detractive impact of its diversification across asset classes. The Fund’s strategic asset allocation positioning maintained exposures to key risk factors, including duration and credit exposure, to enable portfolio diversification. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Equity markets advanced as expectations for a soft landing in the U.S. economy grew. The Russell 1000^® Index posted an approximately 38% return, with U.S. mid cap and small cap equities delivering gains of approximately 35% and 34%, respectively. In comparison, emerging markets and developed markets outside the U.S. generated relatively lower returns of 25% and 23%, respectively. In fixed income markets, the Fed implemented a 50 basis point rate cut in September, coinciding with a decline in inflation. This environment favored longer-duration fixed income assets, which outperformed their shorter-duration counterparts. Credit spreads remained tight, reflecting the continued expectation of a soft landing in the U.S.

The Fund underperformed its primary benchmark for the fiscal year, primarily due to the detractive impact of its diversification across asset classes. The Fund’s strategic asset allocation positioning maintained exposures to key risk factors, including duration and credit exposure, to enable portfolio diversification. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Equity markets advanced as expectations for a soft landing in the U.S. economy grew. The Russell 1000^® Index posted an approximately 38% return, with U.S. mid cap and small cap equities delivering gains of approximately 35% and 34%, respectively. In comparison, emerging markets and developed markets outside the U.S. generated relatively lower returns of 25% and 23%, respectively. In fixed income markets, the Fed implemented a 50 basis point rate cut in September, coinciding with a decline in inflation. This environment favored longer-duration fixed income assets, which outperformed their shorter-duration counterparts. Credit spreads remained tight, reflecting the continued expectation of a soft landing in the U.S.

The Fund underperformed its primary benchmark for the fiscal year, primarily due to the detractive impact of its diversification across asset classes. The Fund’s strategic asset allocation positioning maintained exposures to key risk factors, including duration and credit exposure, to enable portfolio diversification. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.
