Factors Affecting Performance [Text Block]

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

The Fund underperformed its primary benchmark for the fiscal year. The Fund maintained exposure to companies with lower valuation, higher quality and smaller capitalization compared to the benchmark. Overall, the Fund’s factor tilts toward smaller size and away from the most expensive and most volatile stocks was not rewarded. Sector allocation decisions were mixed, as an underweight to healthcare and real estate added to Fund performance, while an overweight to energy and underweight to information technology detracted. Industry allocation was not rewarded mainly due to an underweight to the outperforming semiconductors & semiconductor equipment industry and an overweight to the underperforming insurance and media industries.

Russell Investment Management, LLC fully equitized the Fund’s cash utilizing index futures over the fiscal year, which was beneficial given the positive return of the Russell 1000^® Index during the period.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the fiscal year. One of the Fund’s two money managers outperformed its assigned benchmark. Stock selection was mixed over the period, as selection within the utilities, healthcare and consumer staples sectors was positive while selection in the information technology and communication services sectors detracted. Factor positioning was negative, as tilts toward smaller size and away from the most expensive stocks were not rewarded. Sector allocation detracted over the period, as an overweight to healthcare and underweight to financials detracted from performance. Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio that maintained a tilt away from the most volatile stocks in favor of higher dividend yield, detracted over the fiscal year.

RIM fully equitized the Fund’s cash utilizing index futures over the fiscal year, which was beneficial given the positive return of the Russell 1000^® Value Index during the period.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the fiscal year. None of the Fund’s money managers outperformed their assigned benchmarks. Stock selection was the primary detractor over the period, specifically within the information technology and industrials sectors. Factor positioning was negative, as tilts toward smaller size and away from the most expensive and most volatile stocks were not rewarded. Sector allocation decisions were mixed over the period, as an overweight to healthcare and underweight to communication services detracted from performance, while an overweight to information technology and underweight to energy added to performance. Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio that maintained a tilt away from the most expensive and most volatile stocks, detracted over the fiscal year.

RIM fully equitized the Fund’s cash utilizing index futures over the fiscal year, which was beneficial given the positive return of the Russell 1000^® Index during the period.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its primary benchmark for the fiscal year. One of the Fund’s four money managers outperformed its assigned benchmark for the fiscal year. Stock selection was the primary detractor over the period, as holdings within the information technology and industrials sectors detracted from performance. Factor positioning was negative, as tilts toward smaller size and away from the most expensive and most volatile stocks were not rewarded. Sector allocation decisions were mixed over the period, as an overweight to the healthcare and materials sectors detracted from performance, while an underweight to the real estate sector added to performance. Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio that maintained a tilt away from the most expensive and most volatile stocks, detracted over the fiscal year.

RIM fully equitized the Fund’s cash utilizing index futures over the fiscal year, which was beneficial given the positive return of the Russell 1000^® Index during the period.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the fiscal year. The Fund maintained exposure to companies with lower valuation, higher quality, lower volatility and smaller capitalization compared to the benchmark and these factor tilts were not rewarded. Sector allocations had a mixed impact on performance and were not a significant driver of active returns over the period. Industry allocation was a detractor from performance, specifically via underweight positions in banks and aerospace and defense.

Derivatives were used over the period to equitize a portion of the Fund’s cash, as well as to manage Fund-level country and region exposures on a tactical basis. The Fund’s use of index futures to equitize a portion of the Fund’s cash performed as intended. The tactical exposures contributed positively to overall performance during the period.

The Fund underperformed its secondary benchmark for the fiscal year. Two of the Fund’s three money managers outperformed their assigned benchmarks. With respect to factor exposures, the Fund’s tilt towards quality stocks and smaller capitalization stocks were key detractors.

Stock selection was not beneficial over the period. Russell Investment Management, LLC’s positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio providing exposure to quality, detracted over the fiscal year. The Fund’s use of derivatives to provide preferred positioning with respect to countries and currencies detracted over the fiscal year while the use of index futures to equitize a portion of the Fund’s cash performed as intended.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the fiscal year. Three of the Fund’s four money managers outperformed their assigned benchmarks. With respect to factor exposures, the Fund’s tilts towards quality and low volatility stocks, as well as smaller capitalization stocks were not rewarded. Sector positioning was flat, as an underweight to information technology was ineffective but was partially offset by the positive contribution from an overweight to communication services. Stock selection was generally beneficial over the period. Russell Investment Management, LLC’s positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio providing exposure to quality and reflecting defensive positioning, detracted over the fiscal year. The Fund’s use of derivatives to provide preferred positioning with respect to countries and currencies detracted from the Fund’s performance for the fiscal year while the use of index futures to equitize a portion of the Fund’s cash performed as intended.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its secondary benchmark for the fiscal year. Four of the Fund’s six money managers outperformed their assigned benchmarks. An underweight allocation to India and stock selection within certain sectors in South Korea, India, Taiwan, South Africa and UAE were beneficial to performance. Stock selection within China was the primary headwind to relative returns.

Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio providing exposure to value and momentum factors, was beneficial over the fiscal year. RIM’s other positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio providing exposure to the low volatility factor, reduced tracking error to the Fund’s benchmark but detracted from performance over the fiscal year.

During the fiscal year, RIM used index futures contracts to equitize a portion of the Fund’s cash and this strategy performed as intended. RIM also used index futures contracts to partially hedge country risk in India and Taiwan. These positions served to reduce tracking error to the Fund’s benchmark and had a neutral impact on performance.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its primary benchmark for the fiscal year. One of the Fund’s four money managers outperformed its assigned benchmark. Stock selection was the primary detractor over the period, as holdings within the information technology, industrials and consumer discretionary sectors detracted from performance. Factor positioning was negative, as tilts toward smaller size and away from the most expensive and most volatile stocks were not rewarded. Sector allocation was mixed, as overweights to materials and healthcare detracted while an underweight to real estate positively impacted performance. Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to improve the Fund’s after-tax returns and control Fund-level exposures and risks through the purchase of a stock portfolio that maintained a tilt away from the most expensive and most volatile stocks, detracted over the fiscal year.

RIM fully equitized the Fund’s cash utilizing index futures over the fiscal year, which was beneficial given the positive return of the S&P 500^® Index during the period.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the fiscal year. Two of the Fund’s eight money managers outperformed their assigned benchmarks. Stock selection was negative, with selection in the information technology, financials and industrials sectors detracting from performance. Factor positioning was a negative contributor, with exposure towards higher quality and away from higher volatility stocks detracting from performance. Sector allocation decisions were mixed over the period, as an overweight to the healthcare sector detracted while an underweight to the real estate sector was beneficial. Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to improve the Fund’s after-tax returns and control Fund-level exposures and risks through the purchase of a stock portfolio that maintained a tilt away from the most expensive, lowest quality and most volatile stocks, detracted over the fiscal year.

RIM fully equitized the Fund’s cash utilizing index futures over the fiscal year, which was beneficial given the positive return of the Russell 2500™ Index during the period.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the fiscal year. Four of the Fund’s five money managers outperformed their assigned benchmarks. With respect to factor exposures, the Fund’s underweight to momentum and overweight to quality faced headwinds while an overweight to value was additive. Sector positioning was flat and stock selection detracted from performance over the period. Russell Investment Management, LLC’s positioning strategy, which sought to control Fund-level exposures and risks through the purchase of a stock portfolio providing exposure to quality and low volatility, lagged over the fiscal year. The Fund’s use of derivatives to provide preferred positioning with respect to countries and currencies detracted over the fiscal year while the use of index futures to equitize a portion of the Fund’s cash performed as intended.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its secondary benchmark for the period. Stock selection among office and specialized REITs detracted from performance. Stock selection within the energy and agriculture sectors also had a negative impact. An overweight to toll roads coupled with favorable stock selection within the gas utilities sector was additive.

Money manager performance was mixed for the fiscal year, with one manager outperforming its benchmark and two underperforming their respective benchmarks.

Russell Investment Management, LLC’s (“RIM”) positioning strategy, which sought to improve the Fund’s after-tax returns and control Fund-level exposures and risks through the purchase of a stock portfolio providing broadly diversified exposure to the full set of real asset sub-sectors, outperformed the Fund’s secondary benchmark. Underweight positioning in communications infrastructure and exposure to integrated oil companies both benefited performance.

During the fiscal year, RIM partially equitized the Fund’s cash using index futures contracts to provide the Fund with greater market exposure and this strategy performed as intended.
