Portfolio Turnover:

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 19.09 percent of the average value of its portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time period indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5 percent return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in U.S. equity securities and seeks to reflect the performance of the U.S. large capitalization growth equities market, as measured by the Standard & Poor’s 500 Growth Index. Under normal circumstances, the Fund invests at least 80 percent of the value of its assets in securities of, and investments related to, issuers in the Fund’s benchmark index. The Fund seeks to avoid companies that are deemed inconsistent with the stewardship investing core values. In addition, the Adviser uses optimization techniques to select securities according to their contribution to the Fund’s overall objective and to seek to replicate the characteristics of the index.

Stewardship Investing

The Fund also analyzes potential investments for their ability to reflect certain core social values including:

• Respecting the dignity and value of all people

• Building a world at peace and free from violence

• Demonstrating a concern for justice in a global society

• Exhibiting responsible management practices

• Supporting and involving communities

• Practicing environmental stewardship

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to market risk, which means the value of the Fund’s shares will fluctuate based on market conditions and shareholders could lose money. The value of the Fund’s shares could decline significantly and unexpectedly, based on many factors, including national and international political or economic conditions and general market conditions. Events in the financial markets and in the broader economy may cause uncertainty and volatility, and may adversely affect Fund performance. Events in one market may impact other markets. Future events may impact the Fund in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. The Fund could underperform other investments. Some of the Fund’s holdings may underperform its other holdings. The Fund is also subject to investment style risk, which is the possibility that returns from large capitalization growth stocks will trail returns from other asset classes or the overall stock market. Growth stocks tend to go through cycles of doing better — or worse — than the stock market in general. In the past, these cycles have occasionally persisted for multiple years.

Because the Fund is designed to track the performance of an index, securities may be purchased, retained or sold at times when a more actively managed fund would not do so. If the value of securities that are heavily weighted in the index change, you can expect a greater risk of loss than if the Fund had a lower weighting to those securities. In addition, the Fund does not hold all securities in the index and the performance of the Fund may vary substantially from the performance of the index due to imperfect correlation between the Fund’s holdings and the index. This is also known as tracking error. Application of social screens may contribute to tracking error.

FUND PERFORMANCE

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The bar chart and table that follow provide some indication of the risk of an investment in the Fund. The bar chart shows how the performance of the Class A shares has varied from year to year since its inception. The returns in the bar chart do not reflect any applicable sales charges. If sales charges were included, returns would be lower than those shown, as reflected in the table. The table shows how the Fund’s average annual total returns for different periods compared to those of a broad-based securities market index.

Please note that the Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

The after-tax returns shown were calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. If you hold your Fund shares through a tax-deferred arrangement, such as a 401(k) plan or individual retirement account, the after-tax returns are not relevant.
