Factors Affecting Performance [Text Block]

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

The Fund is a fund-of-funds that diversifies its investments in equity, fixed income, multi-asset and alternative active underlying funds pursuant to Russell Investment Management, LLC’s target strategic asset allocation. The Fund’s performance is therefore a function of its asset allocation, the performance of the asset classes in which it invests and active management results of the underlying funds. During the fiscal year, fixed income performance favored longer-duration government and credit exposures over shorter-duration assets, while equities were led by emerging markets, developed international markets and U.S. large cap equity markets, which outperformed U.S. small cap equities. 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?

The Fund is a fund-of-funds that diversifies its investments in equity, fixed income, multi-asset and alternative active underlying funds pursuant to Russell Investment Management, LLC’s target strategic asset allocation. The Fund’s performance is therefore a function of its asset allocation, the performance of the asset classes in which it invests and active management results of the underlying funds.During the fiscal year, fixed income performance favored longer-duration government and credit exposures over shorter-duration assets, while equities were led by emerging markets, developed international markets and U.S. large cap equity markets, which outperformed U.S. small cap equities. 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?

The Fund is a fund-of-funds that diversifies its investments in equity, fixed income, multi-asset and alternative active underlying funds pursuant to Russell Investment Management, LLC’s target strategic asset allocation. The Fund’s performance is therefore a function of its asset allocation, the performance of the asset classes in which it invests and active management results of the underlying funds.During the fiscal year, fixed income performance favored longer-duration government and credit exposures over shorter-duration assets, while equities were led by emerging markets, developed international markets and U.S. large cap equity markets, which outperformed U.S. small cap equities. Active performance of the underlying funds was mixed, with some underlying funds outperforming their benchmarks and others underperforming their benchmarks.
