Prior Market Index Comparison [Text Block]	LAST TWELVE MONTHS’ PERFORMANCE VS. BENCHMARK For the twelve months ended September 30th, the Fund’s total return trailed both the S&P 500 Index and a blended benchmark composed of 50% domestic equities (S&P 500) and 50% fixed income (Bloomberg Global Aggregate). • Average net allocation to equities (51%) largely accounted for the performance disparity with the S&P 500, which is 100% invested in the securities of 500 of the largest companies listed on U.S. exchanges. • Measured against the 50/50 benchmark, the return gap was attributable to three strategy characteristics: (1) less exposure to fixed income (24% vs. 50%), (2) a portfolio weighting system that moderates the influence from the performance of securities with the largest market capitalization, (3) actively managed security selection that favors value attributes.

Factors Affecting Performance [Text Block]	LAST TWELVE MONTHS’ KEY PERFORMANCE DYNAMICS • At the sub-asset class level, the equity hedge detracted 3% from performance. • As stocks surged, our quantitative work advised less aggressive equity exposure because of pricey valuations, declining investor sentiment, and worsening economic conditions. • Equity concentrations in oil & gas equipment, cable & satellite, and auto retailers dragged down results. • Homebuilding and construction-related stocks were the biggest gainers on an absolute basis and outpaced the S&P 500’s associated exposure. • Equities from Info Tech and Communication Services sectors were additive: semiconductors, software, hardware/storage/peripherals, interactive media, and internet services. • Fixed-income subsets provided positive results, with developed market sovereign debt being the best performer.

Prior Market Index Comparison [Text Block]	LAST TWELVE MONTHS’ PERFORMANCE VS. BENCHMARK For the twelve months ended September 30th, the Fund’s total return trailed both the S&P 500 Index and a blended benchmark composed of 50% domestic equities (S&P 500) and 50% fixed income (Bloomberg Global Aggregate). • Average net allocation to equities (54%) largely accounted for the performance disparity with the S&P 500, which is 100% invested in the securities of 500 of the largest companies listed on U.S. exchanges. • Measured against the 50/50 benchmark, the underperformance was attributable to three strategy characteristics: (1) notably less exposure to fixed income (15% vs. 50%), (2) a stock-weighting system not dominated by the performance of the biggest stocks, (3) actively managed equity selection that favors value attributes.

Factors Affecting Performance [Text Block]	LAST TWELVE MONTHS’ KEY PERFORMANCE DYNAMICS • At the sub-asset class level, the equity hedge detracted 3% from performance. • As stocks surged, our quantitative work advised less aggressive equity exposure because of pricey valuations, declining investor sentiment, and worsening economic conditions. • Equity concentrations in oil & gas equipment, cable & satellite, and auto retailers dragged down results. • Homebuilding and construction-related stocks were the biggest gainers on an absolute basis and outpaced the S&P 500’s associated exposure. • Equities from Info Tech and Communication Services sectors were additive: semiconductors, software, hardware/storage/peripherals, interactive media, and internet services. • Fixed-income subsets provided positive results, with developed market sovereign debt being the best performer.

Factors Affecting Performance [Text Block]	LAST TWELVE MONTHS’ KEY PERFORMANCE DYNAMICS • At the sub-asset class level, the equity hedge detracted nearly 4% from return. • As U.S. stocks surged, global equities followed suit. Our quantitative work advised less aggressive stock exposure due to pricey valuations, declining investor sentiment, and worsening economic conditions. • Equity concentrations in oil & gas exploration, airlines, agricultural products, and construction & farm machinery negatively affected return, and all trailed the MSCI ACWI group holdings. • Of the 30 country investments, none detracted from performance: 26 country allocations positively contributed to return, while the other four were flat. • The industry positions with the biggest upside influence were homebuilding, semiconductor equipment, construction materials, and developed diversified banks. At the sector level, the best holdings were groups associated with Financials, Consumer Discretionary, and Info-Tech sectors. • All fixed-income subsets were profitable, with developed-market sovereign debt up the most.

Prior Market Index Comparison [Text Block]	LAST TWELVE MONTHS’ PERFORMANCE VS. BENCHMARK For the twelve months ended September 30th, the Fund’s total return trailed the MSCI All-Country World Index (ACWI) and underperformed a blended benchmark composed of 50% global equities (MSCI ACWI) and 50% fixed income(Bloomberg Global Aggregate). • Average net allocation to equities (55%) largely accounted for the performance disparity with the MSCI ACWI, which captures large- and mid-cap stock performance across 23 developed markets and 24 emerging markets. • Measured against the 50/50 benchmark, underperformance resulted from three strategy characteristics: (1) notably less exposure to fixed income (16% vs. 50%); (2) a stock-weighting system not dominated by the performance of the biggest stocks; and (3) actively managed equity selection that favors value attributes.

Factors Affecting Performance [Text Block]	LAST TWELVE MONTHS’ KEY PERFORMANCE DYNAMICS • At the sub-asset class level, the equity hedge detracted nearly 4% from return. • As U.S. stocks surged, global equities followed suit. Our quantitative work advised less aggressive stock exposure due to pricey valuations, declining investor sentiment, and worsening economic conditions. • Equity concentrations in oil & gas exploration, airlines, agricultural products, and construction & farm machinery negatively affected return, and all trailed the MSCI ACWI group holdings. • Of the 30 country investments, none detracted from performance: 26 country allocations positively contributed to return, while the other four were flat. • The industry positions with the biggest upside influence were homebuilding, semiconductor equipment, construction materials, and developed diversified banks. At the sector level, the best holdings were groups associated with Financials, Consumer Discretionary, and Info-Tech sectors. • All fixed-income subsets were profitable, with developed-market sovereign debt up the most.

Prior Market Index Comparison [Text Block]	LAST TWELVE MONTHS’ PERFORMANCE VS. BENCHMARK For the twelve months ended September 30th, the Fund’s total return trailed the MSCI All-Country World Index (ACWI) and underperformed a blended benchmark composed of 50% global equities (MSCI ACWI) and 50% fixed income (Bloomberg Global Aggregate). • Average net allocation to equities (55%) largely accounted for the performance disparity with the MSCI ACWI, which captures large- and mid-cap stock performance across 23 developed markets and 24 emerging markets. • Measured against the 50/50 benchmark, underperformance resulted from three strategy characteristics: (1) notably less exposure to fixed income (16% vs. 50%); (2) a stock-weighting system not dominated by the performance of the biggest stocks; and (3) actively managed equity selection that favors value attributes.

Factors Affecting Performance [Text Block]	LAST TWELVE MONTHS’ KEY PERFORMANCE DYNAMICS • Gains from industry allocations that measurably offset losses included electrical components & equipment, leisure facilities & products, application software, cargo ground transportation, and HR & employment services. • From the Energy sector, smaller absolute gains were achieved with stocks linked to oil & gas drilling and integrated oil & gas. • The largest detractor from return was a concentration in Financials stocks, primarily related to the banking industry: asset management & custody banks, regional banks, and investment banking & brokerage. Financial exchanges was another closely aligned Financials group contributing to the year’s loss. • The second worst combination of industries came from the Health Care sector, specifically, health care equipment/services/supplies. • Materials sector holdings also struggled. Gold, metals & mining, and metals/glass & plastic containers, in particular, all lost money.

Factors Affecting Performance [Text Block]	LAST TWELVE MONTHS’ KEY PERFORMANCE DYNAMICS • Homebuilding and construction-related stocks were the biggest gainers on an absolute basis and outpaced the S&P 500’s associated exposure. • Equities from Info Tech and Communication Services sectors were additive: semiconductors, software, hardware/storage/peripherals, interactive media, and internet services. • Equity concentrations in oil & gas equipment, cable & satellite, and auto retailers dragged down results. • In addition to being the biggest allocation all year, Info-Tech industries were the best-performing exposures; however, the net result trailed the benchmark due to the Fund’s discipline to minimize the performance influence from the largest holdings, in contrast to the index, by capping their portfolio weighting.

Prior Market Index Comparison [Text Block]	LAST TWELVE MONTHS’ PERFORMANCE VS. BENCHMARK For the twelve months ended September 30th, the Fund’s total return underperformed the S&P 500 Index. • The S&P 500 benefited from the surge in the prices of seven stocks. The combined weight of those equities ballooned to almost one-third of the index and accounted for 41% of its twelve-month total return. • For risk control, the Fund’s stock positions are assigned weights using a system that avoids the possibility that a handful of the largest stocks could drive overall portfolio performance. • The equity selection process employed by the Fund leans toward value attributes and industries poised for leadership, rather than equity segments that have already boomed and reflect expensive valuations.
