Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 5.27%, compared to a return of 4.83% for the Fund’s Secondary Benchmark. The Fund outperformed the Secondary Benchmark for the fiscal year primarily due to the implementation of the Fund’s Variable Maturity Strategy, during which the Fund’s overall average maturity is lengthened or shortened depending on the availability of securities in the marketplace deemed to have higher expected returns by the Fund’s Sub-Adviser. During periods of the fiscal year when interest rates were rising, the Fund was overweight relative to the Secondary Benchmark in shorter maturities, while later in the fiscal year, as rates receded, the Fund began extending its maturity positioning. Overall these changes in maturity in the Fund helped the Fund outperform the Secondary Benchmark.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 15.96%, compared to a return of 17.49% for the Fund’s Secondary Benchmark. The Fund underperformed this Benchmark during the fiscal year by 1.53%, after deducting the Fund’s net operating expenses for the year. Across the fiscal year the Fund avoided holding positions in the stocks of companies whose ratio of price-to-book-value was above the average level in the marketplace (“growth-oriented stocks”). These growth-oriented stocks - particularly those with larger market capitalization - significantly outperformed the other stocks maintained in the Fund's Secondary Benchmark, leading to the Fund's underperformance of this Benchmark.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 11.43%, compared to a return of 10.05% for the Fund’s Secondary Benchmark. The Fund outperformed this Benchmark during the fiscal year by 1.38% after deducting the Fund’s net operating expenses for the year. The Fund’s outperformance relative to its benchmark index over the fiscal year was the result of multiple factors. First, the Fund tends to exclude stocks of real estate investment trusts in a year when REITs exhibited weak performance. Also contributing to the Fund’s outperformance against its benchmark index was the Fund’s tendency to avoid stocks that have higher price-to-book ratios and that have low rates of profitability - such stocks exhibited very weak performance during the fiscal year.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 12.57%, compared to a return of 12.67% for the Fund’s Secondary Benchmark. The Fund underperformed the Secondary Benchmark during the fiscal year by 0.10% after deducting the Fund’s net operating expenses for the year. Across the fiscal year the Fund had a greater holding of stocks with the lowest ratios of price-to-book-value (commonly called "deep value stocks") than does the Secondary Benchmark. Such deep value stocks had returns during the fiscal year that were stronger than the overall return of this Benchmark, hence the Fund’s emphasis on those stocks provided the Fund with an initial level of outperformance to the Secondary Benchmark prior to the deduction of net operating expenses. However, with the deduction of net operating expenses, the Fund's resulting performance was slightly less than that of the Secondary Benchmark.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 9.86%, compared to a return of 7.75% for the Fund’s Secondary Benchmark. The Fund outperformed the Secondary Benchmark during the fiscal year by 2.11% after deducting the Fund’s net operating expenses for the year. The Fund’s outperformance relative to the Secondary Benchmark across the fiscal year was due primarily to the Fund’s exclusion of real estate securities, which had negative performance during the fiscal year, as well as the Fund's lower allocation to low profitability growth stocks, which also performed negatively during the year.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 16.83%, compared to a return of 14.08% for the Fund’s Secondary Benchmark. The Fund outperformed the Secondary Benchmark during the fiscal year by 2.75% after deducting the Fund’s net operating expenses for the year. Across the fiscal year the Fund maintained a larger position than that of the Secondary Benchmark in the stocks of companies whose ratio of price-to-book-value was among the lowest in the marketplace (known as “deeper value stocks”). During the fiscal year, deeper value stocks exhibited strong performance overall relative to the other stocks in the Secondary Benchmark, contributing to the Fund’s outperformance relative to this Benchmark.

The Fund essentially experienced an equivalent level of return during the fiscal year as did the Secondary Benchmark, after deducting the Fund’s net operating expenses for the year. During the fiscal year, the Fund’s portfolio before deducting fees and expenses outperformed the Secondary Benchmark moderately by avoiding a small number of REITs held in the Benchmark that exhibited weak performance during the fiscal year, but after the deduction of fees and expenses, the Fund's net performance roughly equaled that of the Benchmark.

Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? Investment performance of the Fund is judged against the performance of certain market indexes. Effective June 30, 2024, for this Fund, performance is compared to a broad-based securities market index (the “Primary Benchmark”) known as the Morningstar ® ® For the fiscal year ended June 30, 2024, the Fund had a net return of 12.87%, compared to a return of 14.11% for the Fund’s Secondary Benchmark. Since the Fund invests exclusively in shares of the SA Fund family (the “Underlying Funds”), the performance of the Fund relative to the Secondary Benchmark is driven primarily by the performance of each of the Underlying Funds against the relevant components of that Benchmark. For the fiscal year, three of the eight underlying funds contributed positively to relative performance, notably the SA US Fixed Income Fund. Five of the eight underlying funds contributed negatively to relative performance this quarter, most notably the SA US Core Market Fund, the SA Global Fixed Income Fund, and the SA US Value Fund.
