Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

Strong equity performance and beneficial positioning of the TOPS bond holdings led to 2024 returns for each portfolio which were above our estimates coming into the year. A favorable finish to 2024 propelled U.S. large cap growth stocks to qualify as the top-performing asset class in the TOPS Portfolios in 2024 and annualized for the last 5 years as well. Fortunately for TOPS investors, large cap growth stocks are the top (or within 1% of the top) target allocation in all our growth-focused portfolios. With the job of diversifying assets amongst a wide range of global asset classes, we are pleased we allocated highly to the best-performing asset class.  On the bond side of our portfolios, we currently utilize primarily 11 different fixed income-oriented asset classes. We are again happy to report that the majority of those 11 positions outperformed the Bloomberg US Aggregate Bond Index in 2024. We are pleased to see our focus on interest rate and credit positioning reward our investors again this year.  For the year, domestic equities remained solidly positive. Large cap (S&P 500 Total Return Index) was up +25.0%, leading all domestic equity asset classes. Mid cap (S&P Midcap 400 Total Return Index) returned +13.9%, while small cap (S&P Small Cap 600 Total Return Index) trailed but still posted +8.7%. Developed international (MSCI EAFE Total Return USD Index) was up +3.8% while emerging markets (MSCI Emerging Markets Total Return USD Index) returned +7.5%. Barclay's US Aggregate Bond Index returned +1.3%, while Barclay's US TIPs Index outperformed slightly with a return of +1.8%. Global natural resources (S&P GSSI North America Natural Resources Total Return Index) were up +8.1%. Global real estate (MSCI World Real Estate Total Return Index) managed to stay positive with a return of +2.1%.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

Strong equity performance and beneficial positioning of the TOPS bond holdings led to 2024 returns for each portfolio which were above our estimates coming into the year. A favorable finish to 2024 propelled U.S. large cap growth stocks to qualify as the top-performing asset class in the TOPS Portfolios in 2024 and annualized for the last 5 years as well. Fortunately for TOPS investors, large cap growth stocks are the top (or within 1% of the top) target allocation in all our growth-focused portfolios. With the job of diversifying assets amongst a wide range of global asset classes, we are pleased we allocated highly to the best-performing asset class.  On the bond side of our portfolios, we currently utilize primarily 11 different fixed income-oriented asset classes. We are again happy to report that the majority of those 11 positions outperformed the Bloomberg US Aggregate Bond Index in 2024. We are pleased to see our focus on interest rate and credit positioning reward our investors again this year.  For the year, domestic equities remained solidly positive. Large cap (S&P 500 Total Return Index) was up +25.0%, leading all domestic equity asset classes. Mid cap (S&P Midcap 400 Total Return Index) returned +13.9%, while small cap (S&P Small Cap 600 Total Return Index) trailed but still posted +8.7%. Developed international (MSCI EAFE Total Return USD Index) was up +3.8% while emerging markets (MSCI Emerging Markets Total Return USD Index) returned +7.5%. Barclay's US Aggregate Bond Index returned +1.3%, while Barclay's US TIPs Index outperformed slightly with a return of +1.8%. Global natural resources (S&P GSSI North America Natural Resources Total Return Index) were up +8.1%. Global real estate (MSCI World Real Estate Total Return Index) managed to stay positive with a return of +2.1%.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

Strong equity performance and beneficial positioning of the TOPS bond holdings led to 2024 returns for each portfolio which were above our estimates coming into the year. A favorable finish to 2024 propelled U.S. large cap growth stocks to qualify as the top-performing asset class in the TOPS Portfolios in 2024 and annualized for the last 5 years as well. Fortunately for TOPS investors, large cap growth stocks are the top (or within 1% of the top) target allocation in all our growth-focused portfolios. With the job of diversifying assets amongst a wide range of global asset classes, we are pleased we allocated highly to the best-performing asset class.  On the bond side of our portfolios, we currently utilize primarily 11 different fixed income-oriented asset classes. We are again happy to report that the majority of those 11 positions outperformed the Bloomberg US Aggregate Bond Index in 2024. We are pleased to see our focus on interest rate and credit positioning reward our investors again this year.  For the year, domestic equities remained solidly positive. Large cap (S&P 500 Total Return Index) was up +25.0%, leading all domestic equity asset classes. Mid cap (S&P Midcap 400 Total Return Index) returned +13.9%, while small cap (S&P Small Cap 600 Total Return Index) trailed but still posted +8.7%. Developed international (MSCI EAFE Total Return USD Index) was up +3.8% while emerging markets (MSCI Emerging Markets Total Return USD Index) returned +7.5%. Barclay's US Aggregate Bond Index returned +1.3%, while Barclay's US TIPs Index outperformed slightly with a return of +1.8%. Global natural resources (S&P GSSI North America Natural Resources Total Return Index) were up +8.1%. Global real estate (MSCI World Real Estate Total Return Index) managed to stay positive with a return of +2.1%.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

Strong equity performance and beneficial positioning of the TOPS bond holdings led to 2024 returns for each portfolio which were above our estimates coming into the year. A favorable finish to 2024 propelled U.S. large cap growth stocks to qualify as the top-performing asset class in the TOPS Portfolios in 2024 and annualized for the last 5 years as well. Fortunately for TOPS investors, large cap growth stocks are the top (or within 1% of the top) target allocation in all our growth-focused portfolios. With the job of diversifying assets amongst a wide range of global asset classes, we are pleased we allocated highly to the best-performing asset class.  On the bond side of our portfolios, we currently utilize primarily 11 different fixed income-oriented asset classes. We are again happy to report that the majority of those 11 positions outperformed the Bloomberg US Aggregate Bond Index in 2024. We are pleased to see our focus on interest rate and credit positioning reward our investors again this year.  For the year, domestic equities remained solidly positive. Large cap (S&P 500 Total Return Index) was up +25.0%, leading all domestic equity asset classes. Mid cap (S&P Midcap 400 Total Return Index) returned +13.9%, while small cap (S&P Small Cap 600 Total Return Index) trailed but still posted +8.7%. Developed international (MSCI EAFE Total Return USD Index) was up +3.8% while emerging markets (MSCI Emerging Markets Total Return USD Index) returned +7.5%. Barclay's US Aggregate Bond Index returned +1.3%, while Barclay's US TIPs Index outperformed slightly with a return of +1.8%. Global natural resources (S&P GSSI North America Natural Resources Total Return Index) were up +8.1%. Global real estate (MSCI World Real Estate Total Return Index) managed to stay positive with a return of +2.1%.
