This example is intended to help you compare the cost of investing in Institutional Class and Individual Investor Class shares of the Mid Cap Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class or Individual Investor Class shares of the Mid Cap Fund for the time periods indicated and then redeems all of his or her shares at the end of those periods. The table also assumes that the investment has a 5% return each year, that all dividends and distributions are reinvested and that the Mid Cap Fund’s operating expenses remain the same throughout those periods. Although an investor’s actual expenses may be higher or lower than those shown in the table, based on these assumptions his or her expenses would be:

rr_StrategyNarrativeTextBlock

The Mid Cap Fund follows a sustainable investing approach, combining rigorous financial analysis with equally rigorous environmental, social and governance (ESG) analysis in order to identify investments.

Under normal market conditions, the Mid Cap Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities (such as common stocks, securities convertible into common or preferred stocks and warrants) of companies that, when purchased, have capitalizations within the range of the Russell Midcap Index as measured by market capitalization. As of December 31, 2015, the Russell Midcap Index included companies with market capitalizations ranging from approximately $386 million to $30.5 billion.

The Mid Cap Fund selects equity securities on a company-by-company basis primarily through the use of fundamental analysis. The portfolio manager may overweight or underweight specific sectors and may take concentrated positions, which could lead to increased volatility. The Mid Cap Fund is not constrained by any particular investment style, and may therefore invest in “growth” stocks, “value” stocks or a combination of both. Additionally, it may buy stocks in any sector or industry.

The Mid Cap Fund may invest up to 45% of its assets in securities of non-U.S. issuers, including American Depositary Receipts (“ADRs”), but may invest no more than 25% of its assets in securities of non-U.S. issuers other than ADRs. The Mid Cap Fund’s investments in securities of non-U.S. issuers, if any, may be diversified across multiple countries or geographic regions, or may be focused in a single country or geographic region.

The Mid Cap Fund may utilize derivatives for hedging and for investment purposes.

rr_RiskNarrativeTextBlock

• Market Risk Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of the Fund’s investments. To the extent the Fund concentrates its investments in one or more specific sectors, countries or regions, the Fund will be subject to the risks associated with such sector(s), country(ies) or region(s) to a greater extent than would be a more broadly diversified fund.

• Derivatives Risk Derivatives involve special risks and may result in losses. The values of derivatives can be very volatile, especially in unusual market conditions, and that volatility can be exacerbated by the use of leverage, which is common for derivative strategies. Derivatives may be illiquid, and may also be subject to the risk of nonperformance by a transaction counterparty. The Fund may not be able to enter into, or terminate, a derivatives position when desired. Derivatives are also subject to the risks of mispricing and improper valuation, and may increase the amount of taxes payable by shareholders.

• Non-U. S. Securities Risk Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.

• Turnover Risk Frequent changes in the securities held by a Fund increases the Fund’s transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund’s performance.

• Growth Securities Risk Growth securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.

• Small and Medium-Sized Capitalization Company Risk Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.

• Value Securities Risk Value securities are securities the investment adviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.

As with all mutual funds, investors may lose money by investing in the Mid Cap Fund.

This example is intended to help you compare the cost of investing in Institutional Class, Individual Investor Class and Class R shares of the Balanced Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class, Individual Investor Class or Class R shares of the Balanced Fund for the time periods indicated and then redeems all of his or her shares at the end of those periods. The table also assumes that the investment has a 5% return each year, that all dividends and distributions are reinvested and that the Balanced Fund’s operating expenses remain the same throughout those periods. Although an investor’s actual expenses may be higher or lower than those shown in the table, based on these assumptions his or her expenses would be:

rr_StrategyNarrativeTextBlock

The Balanced Fund follows a sustainable investing approach, combining rigorous financial analysis with equally rigorous environmental, social and governance (ESG) analysis in order to identify investments.

The Balanced Fund normally expects to invest (directly or indirectly through mutual funds and/or exchange-traded funds (“ETFs” and, together with mutual funds, “Underlying Funds”)) approximately 60–75% of its assets in equity securities and approximately 25–40% of its assets in debt securities, though this allocation may vary somewhat depending on market conditions.

With respect to the equity portion of its portfolio, the Balanced Fund’s portfolio managers intend to use a team approach to manage a high conviction, core growth portfolio of primarily large cap securities and a smaller allocation to core, mid- and small-cap securities of high quality, attractively valued companies. The portfolio managers utilize an investment process combining fundamental analysis with a focus on valuation and volatility reduction.

With respect to the debt portion of the portfolio, the Balanced Fund intends to invest primarily in obligations, including mortgage-related securities, issued or guaranteed by the United States government or its agencies and instrumentalities and corporate bonds that are, at the time of purchase, rated at least investment grade (rated BBB- or higher by Standard & Poor’s Ratings Group or Baa or higher by Moody’s Investors Service) or unrated and determined by the Adviser to be of comparable quality. Although the Fund is not constrained with respect to duration, the debt portion of the Fund is normally intended to be managed with only moderate deviation in duration from the broad market.

The Balanced Fund’s portfolio managers use both qualitative analysis and quantitative techniques when allocating the Balanced Fund’s assets between equity securities and debt securities.

The Balanced Fund may invest up to 45% of its assets in securities of non-U.S. issuers, including emerging market investments and American Depositary Receipts (“ADRs”), but may invest no more than 25% of its assets in securities of non-U.S. issuers other than ADRs.

The Balanced Fund may utilize derivatives for hedging and for investment purposes.

rr_RiskNarrativeTextBlock

• Market Risk Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of the Fund’s investments.

• Derivatives Risk Derivatives involve special risks and may result in losses. The values of derivatives can be very volatile, especially in unusual market conditions, and that volatility can be exacerbated by the use of leverage, which is common for derivative strategies. Derivatives may be illiquid, and may also be subject to the risk of nonperformance by a transaction counterparty. The Fund may not be able to enter into, or terminate, a derivatives position when desired. Derivatives are also subject to mispricing and improper valuation, and may increase the amount of taxes payable by shareholders.

• Non-U. S. Securities Risk Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.

• Interest Rate Risk The value of debt securities tends to decrease when nominal interest rates rise. Longer-duration securities tend to be more sensitive to interest rate changes, and thus more volatile, than shorter-duration securities. A period of rising interest rates may negatively affect the Fund’s performance.

• Liquidity Risk Liquidity risk is the risk associated with a lack of marketability of investments, which may make it difficult to sell an investment at a desirable time or price. A lack of liquidity may cause the value of an investment to decline. The Fund may have to lower the selling price, sell other investments, or forego another, more appealing investment opportunity. Changing regulatory and market conditions, including a decline in the number or capacity of financial institutions to make markets in the Fund’s investments, as well as increases in interest rates or credit spreads, may adversely affect the liquidity of the Fund’s investments. Illiquid investments may also be more difficult to value, and judgment plays a larger role in valuing these investments as compared to valuing more liquid investments.

• Credit Risk Changing economic conditions may adversely affect an obligated entity’s actual or perceived ability to pay interest or principal on a fixed income security when due, which in turn can adversely affect the price of or income derived from the security.

• Allocation Risk The allocation techniques and decisions of the investment adviser may not produce the desired results.

• U.S. Government Securities Risk U.S. government securities that are not issued or guaranteed by the U.S. Treasury are generally more susceptible to loss than are securities that are so issued or guaranteed.

• Mortgage Risk Mortgage related securities tend to become more sensitive to interest rate changes as interest rates rise, increasing their volatility. When interest rates decline, underlying borrowers may pay off their loans sooner than expected, forcing the Fund to reinvest disposition proceeds at lower prevailing interest rates.

• Reinvestment Risk Income from the Fund’s investments may decline if the Fund is forced to invest the proceeds from matured, called or otherwise disposed of debt securities or convertible securities at interest rates that are below the Fund’s earnings rate at that time.

• Growth Securities Risk Growth securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.

• Small- and Medium-Sized Capitalization Company Risk Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.

• Value Securities Risk Value securities are securities the investment adviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.

As with all mutual funds, investors may lose money by investing in the Balanced Fund.

Pax MSCI International ESG Index Fund

(the “International Index Fund”)

Summary of Key Information

Fees and expenses of the fund, narrative

rr_ObjectivePrimaryTextBlock

The International Index Fund seeks investment returns that closely correspond to the price and yield performance, before fees and expenses, of the MSCI EAFE ESG Index.

rr_ExpenseNarrativeTextBlock

The tables below describe the fees and expenses that you may pay if you buy and hold Institutional Class, Individual Investor or Class R shares of the Fund.

Annual fund operating expenses, heading

rr_OperatingExpensesCaption

Annual Fund Operating Expenses (expenses you pay each year as a percentage of the value of your investment):

Portfolio turnover, narrative

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 rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These transaction costs, which are not reflected in “Annual Fund Operating Expenses” or in the “Example of Expenses,” affect the Fund’s performance. During the International Index Fund’s most recent fiscal year, the International Index Fund’s portfolio turnover rate was 86%* of the average value of the portfolio.

* To manage cash flows, minimize trading costs and equitize cash balances in between trading blocks of securities, the International Index Fund utilizes one or more exchange-traded funds (ETFs) which have an investment objective that tracks the Fund’s broad-based benchmark. These investments are frequent and short-term, however, the Fund is required to include such ETF investment activity in the calculation of its portfolio turnover. Had such transactions been excluded, the portfolio turnover would have been 8% for the year ended December 31, 2015.

Performance, Narrative

rr_PerformanceNarrativeTextBlock

Effective March 31, 2014 the Pax MSCI International ESG Index Fund acquired the assets of Pax World International Fund, a series of Pax World Funds Series Trust I, and of Pax MSCI EAFE ESG Index ETF, a series of Pax World Funds Trust II, pursuant to an Agreement and Plan of Reorganization dated December 13, 2013 (the “Reorganizations”). Because the Pax MSCI International ESG Index Fund had no investment operations prior to the closing of the Reorganizations, and based on the similarity of the Pax MSCI International ESG Index Fund to Pax MSCI EAFE ESG Index ETF, Pax MSCI EAFE ESG Index ETF (the “Predecessor Fund”) is treated as the survivor of the Reorganizations for accounting and performance reporting purposes. Accordingly, all performance and other information shown for the Fund for periods prior to March 31, 2014 is that of the Predecessor Fund.

The bar chart below presents the calendar year total returns for Institutional Class shares of the International Index Fund before taxes. The bar chart is intended to provide some indication of the risk of investing in the International Index Fund by showing changes in the International Index Fund’s performance from year to year. All performance information shown for the International Index Fund for periods prior to March 31, 2014 is that of the Predecessor Fund. As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of future performance.

Unlike the International Index Fund, the MSCI EAFE ESG Index and the MSCI EAFE Index and the Lipper International Large-Cap Core Funds Index are not investments, are not professionally managed, and (with the exception of the Lipper International Large-Cap Core Funds Index) do not reflect deductions for fees, expenses or taxes. One cannot invest directly in any index.

Pax Global Environmental Markets Fund

(the “Global Environmental Markets Fund”)

Summary of Key Information

Fees and expenses of the fund, narrative

rr_ObjectivePrimaryTextBlock

The Global Environmental Markets Fund’s investment objective is to seek long term growth of capital by investing in innovative companies around the world whose businesses and technologies focus on environmental markets, including alternative energy and energy efficiency; water infrastructure technologies and pollution control; environmental support services and waste management technologies; and sustainable food, agriculture and forestry.

rr_ExpenseNarrativeTextBlock

The tables below describe the fees and expenses that you may pay if you buy and hold Institutional Class, Individual Investor Class, Class A or Class R shares of the Global Environmental Markets Fund. You may qualify for sales charge discounts for Class A shares if you and your spouse or minor children invest, or agree to invest in the future, at least $50,000 in Class A shares of the Global Environmental Markets Fund. More information about these and other discounts is available from your financial intermediary, under “Shareholder Guide—Sales Charges” on page 123 of this Prospectus and under “Distribution and Shareholder Services—Sales Charge Reductions and Waivers” on page 87 in the Statement of Additional Information.

This example is intended to help you compare the cost of investing in Institutional Class, Individual Investor Class, Class A and Class R shares of the Global Environmental Markets Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class, Individual Investor Class, Class A or Class R shares of the Global Environmental Markets Fund for the time periods indicated and then redeems all of his or her shares at the end of those periods. The table also assumes that the investment has a 5% return each year, that all dividends and distributions are reinvested and that the Global Environmental Markets Fund’s operating expenses remain the same throughout those periods. Although an investor’s actual expenses may be higher or lower than those shown in the table, based on these assumptions his or her expenses would be:

rr_StrategyNarrativeTextBlock

The Global Environmental Markets Fund follows a sustainable investing approach, combining rigorous financial analysis with equally rigorous environmental, social and governance (ESG) analysis in order to identify investments. Under normal market conditions, the Global Environmental Markets Fund will invest primarily in equity securities (such as common stocks, preferred stocks and securities convertible into common and preferred stocks) of companies located around the world, including at least 40% of its net assets in securities of non-U.S. issuers, including those located in emerging markets. The Fund’s investments may be diversified across multiple countries or geographic regions, or may be focused on a select geographic region, although the Global Environmental Markets Fund will normally have investments in a minimum of three countries other than the United States.

The Global Environmental Markets Fund invests in environmental markets—companies whose businesses and technologies focus on environmental markets, including alternative energy and energy efficiency; water infrastructure technologies and pollution control; environmental support services and waste management technologies; and sustainable food, agriculture and forestry. The Global Environmental Markets Fund’s portfolio manager selects equity securities on a company-by-company basis primarily through the use of fundamental analysis. The Global Environmental Markets Fund is not constrained by any particular investment style, and may therefore invest in “growth” stocks, “value” stocks or a combination of both. Additionally, it may buy stocks in any sector or industry, and it is not limited to investing in securities of a specific market capitalization.

The Global Environmental Markets Fund may utilize derivatives for hedging and for investment purposes.

The Global Environmental Markets Fund seeks to invest in companies with positive overall environmental performance and whose products or services help other companies and countries improve their environmental performance, and avoids investing in companies with significant environmental problems or worsening environmental profiles. In addition, the Fund strives to be fossil fuel-free (avoiding investing in companies that PWM determines are significantly involved in the extraction and/or refining of fossil fuels).

rr_RiskNarrativeTextBlock

• Market Risk Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of the Fund’s investments.

• Derivatives Risk Derivatives involve special risks and may result in losses. The values of derivatives can be very volatile, especially in unusual market conditions, and that volatility can be exacerbated by the use of leverage, which is common for derivative strategies. Derivatives may be illiquid, and may also be subject to the risk of nonperformance by a transaction counterparty. The Fund may not be able to enter into, or terminate, a derivatives position when desired. Derivatives are also subject to mispricing and improper valuation, and may increase the amount of taxes payable by shareholders.

• Non-U. S. Securities Risk Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.

• Turnover Risk Frequent changes in the securities held by a Fund increases the Fund’s transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund’s performance.

• Growth Securities Risk Growth securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.

• Small- and Medium-Sized Capitalization Company Risk Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.

• Value Securities Risk Value securities are securities the investment adviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.

As with all mutual funds, investors may lose money by investing in the Global Environmental Markets Fund.

Average Annual Total Returns The performance table below presents the average annual total returns for Individual Investor Class, Class A, Institutional Class and Class R shares of the Global Environmental Markets Fund. The performance table is intended to provide some indication of the risks of investment in the Global Environmental Markets Fund by showing how the Global Environmental Markets Fund’s average annual total returns compare with the returns of a broad-based securities market index over a one-year, five-year and ten-year period. After-tax performance is presented only for Individual Investor Class shares of the Fund. After-tax returns for Class A, Institutional Class and Class R shares may vary. After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the effect of local, state or foreign taxes. Actual after-tax returns will depend on a shareholder’s own tax situation and may differ from those shown. After-tax returns may not be relevant to shareholders who hold their shares through tax-advantaged arrangements (such as 401(k) plans and individual retirement accounts). As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of future performance.
