The U.S. dollar appreciated marginally relative to most other developed-markets currencies during this time. Against this backdrop, the Fund outperformed its benchmark by 1.02% for the fiscal year. The outperformance was primarily driven by an underweight to U.S. Treasuries and security selection. | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? What affected the Fund’s performance? For the fiscal year ended June 30, 2024, the Fund returned 9.06%, underperforming its benchmark, the MSCI EAFE Index, which returned 11.54% for the period. For the year, the U.S. dollar generally appreciated versus the currencies of other developed regions, detracting from the returns of international securities for U.S. investors. Emerging markets performance was stronger than developed markets. In non-U.S developed markets, value stocks outperformed growth stocks, and large-capitalization stocks outperformed small-capitalization stocks. Consumer staples and utilities struggled over the year, while information technology and financials generated the strongest returns. Compared to its benchmark, the Fund’s relative underperformance was driven by stock selection within certain sectors. Weak stock selection, particularly in health care, financials, and industrials detracted from relative returns. Sector allocation, such as the underweight to financials, also detracted from returns. Strong stock selection and an overweight in information technology contributed to returns, helping to partially offset the detractors. Global growth has stayed resilient despite higher borrowing costs, bolstered by U.S. strength. As major central banks start cutting rates to normalize policy, early signs of recovery outside the U.S. are starting to emerge. A modest eurozone recovery appears to be | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? What affected the Fund’s performance? The Fund returned 3.86% during the fiscal year ended June 30, 2024. The Fund outperformed its benchmark, the Bloomberg U.S. Aggregate Bond Index, which returned 2.63% during the same period. A 25 basis point ("bps", 1bps equal 0.01%) hike in July of 2023 capped off the U.S. Federal Reserve’s most aggressive rate hiking cycle in recent memory as it sought to reduce inflation toward its 2% long term target. Weakening inflation data in late 2023 renewed the optimism of market participants that inflation could be tamed. This resulted in the market pricing in numerous rate cuts heading into 2024. The first quarter of 2024 saw a reversal of that sentiment as rates rose on unexpectedly strong economic and inflation data in February and March, resulting in a resetting of expectations as the market came to terms with the potential for interest rates to remain elevated. Altogether, the 10-Year U.S. Treasury rate rose from 3.81% on June 30, 2023, to 4.37% on June 30, 2024, and while interest rate volatility moderated, it remained elevated relative to recent history. The yield curve remained inverted throughout the fiscal year, meaning that short-term rates were higher than long-term rates. Meanwhile, corporate credit spreads narrowed over the period, particularly within U.S. high-yield, leading to gains for U.S. corporate bonds and other credit-sensitive areas of the market. Emerging market debt also performed well, while the non-U.S. developed bond | |

In addition, within the overall large capitalization portion of the market, value stocks underperformed growth stocks for the one-year period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? What affected the Fund’s performance? For the fiscal year ended June 30, 2024, the Fund returned 25.17%, outperforming its benchmark, the S&P 500 Index, which returned 24.56% for the period. For the year, within large-capitalization stocks, approximately half of the benchmark’s performance came from the technology sector’s roughly 42% return, contributing nearly 12% of the benchmark’s 24.56% return. The technology sector’s significant outperformance and its 29% weight in the benchmark created a challenging market environment for other sectors to keep up with the performance of the benchmark overall. Only one other sector, communication services, was able to outperform the broader market, while the other nine lagged. Real estate, utilities and materials were the worst performing sectors for the year. In addition, within the overall large-capitalization portion of the market, value stocks underperformed growth stocks for the 1-year period. Against this backdrop, the Fund managed to outperform its benchmark through strong stock selection. While the concentrated performance within the technology sector was a headwind, the Fund’s strong stock selection in industrials, consumer discretionary and financials more than offset it, supporting the Fund’s modest outperformance for the fiscal year. | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? What affected the Fund’s performance? For the fiscal year ended June 30, 2024, the Fund returned 9.75%, underperforming its benchmark, the MSCI EAFE Index, which returned 11.54% for the period. For the year, the U.S. dollar generally appreciated versus the currencies of other developed regions, detracting from the returns of international securities for U.S. investors. Emerging markets performance was stronger than developed markets. In non-U.S developed markets, value stocks outperformed growth stocks, and large-capitalization stocks outperformed small-capitalization stocks. Consumer staples and utilities struggled over the year, while information technology and financials generated the strongest returns. Compared to its benchmark, the Fund’s relative underperformance was driven by stock selection within certain sectors. Weak stock selection, particularly in consumer discretionary, financials, and industrials detracted from relative returns. Sector allocation, such as the overweight to information technology contributed to returns, helping to partially offset the weak stock selection. Global growth has stayed resilient despite higher borrowing costs, bolstered by U.S. strength. As major central banks start cutting rates to normalize policy, early signs of recovery outside the U.S. are starting to emerge and a modest eurozone recovery appears to be underway. | |
