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 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 Large Cap Fund's performance. During the Large Cap Fund's most recent fiscal year, the Large Cap Fund's portfolio turnover rate was 54% 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 Institutional Class or 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 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:

Strategy Narrative [Text Block]

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, 2018, the Russell Midcap Index included companies with market capitalizations ranging from approximately $387 million to $67.9 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 significant 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"). The Mid Cap Fund 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.

It is possible that, due to its investment strategies, the portfolio turnover rate of the Mid Cap Fund may be significant. Portfolio turnover is not a principal consideration in investment decisions for the Fund, and the Fund is not subject to any limit on the frequency with which portfolio securities may be purchased or sold.

Risk Narrative [Text Block]

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 takes significant positions 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.

●

Equity Securities Risk The market price of equity securities may fluctuate significantly, rapidly and unpredictably, causing the Fund to experience losses. The prices of equity securities generally are more volatile than the prices of debt securities.

●

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 also may be 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.

●

Management Risk The Fund is actively managed. The investment techniques and decisions of the investment adviser and the Fund's portfolio manager(s) may not produce the desired results.

●

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.

The foregoing descriptions are only summaries. Please see "About the Funds—Principal Risks" on page 116 for more detailed descriptions of the foregoing risks.

This example is intended to help you compare the cost of investing in Institutional Class, Investor Class or Class A shares of the ESG Beta Quality Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class, Investor Class or Class A shares of the ESG Beta Quality 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 ESG Beta Quality 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:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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

"ESG Beta" is a term indicating that the Fund follows a "smart beta" or factor strategy incorporating ESG along with financial factors in its investment approach. In this type of investing, a portfolio of securities is overweighted toward certain factors in an effort to enhance return and/or reduce risk.

Under normal market conditions, the Fund invests primarily in large-capitalization domestic equity securities that the Adviser believes have strong Environmental, Social and Governance (ESG) profiles and that exhibit higher "quality" characteristics and reasonable valuations. Specifically, the strategy favors securities with stronger ESG scores (as determined by the Adviser), higher profitability, higher earnings quality (based on a quantitative assessment of operating fundamentals and accruals), lower risk (i.e., the historic volatility of a security relative to the overall market) and lower valuations relative to the Russell 1000 Index. The portfolio managers may take significant positions in companies in the information technology sector, which could lead to increased volatility.

The Adviser utilizes a quantitative process, optimizing ESG, quality factors and valuation factors relative to benchmark constraints.

ESG scores are calculated based on the Adviser's assessment of an issuer's ESG profile. The scores emphasize management of ESG-related risks, incorporate ESG trends (taking into account progress or regression in a company's ESG profile) and adjust for involvement in significant ESG-related controversies.

Quality factors include but are not limited to quantitative determinations of profitability, earnings quality and risk. Valuation is determined by considering a combination of earnings-based valuation measures.

The Fund may invest a portion 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 Fund may utilize derivatives for hedging and for investment purposes.

Risk Narrative [Text Block]

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 also may be 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.

●

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.

●

Equity Securities Risk The market price of equity securities may fluctuate significantly, rapidly and unpredictably, causing the Fund to experience losses. The prices of equity securities generally are more volatile than the prices of debt securities.

●

Value Securities Risk The Fund may invest in companies that may not be expected to experience significant earnings growth, but whose securities the investment adviser believes are selling at a price lower than their true value. Companies that issue value securities may have experienced adverse business developments or may be subject to special risks that have caused their securities to be out of favor. If the investment adviser's assessment of a company's prospects is wrong, or if the market does not recognize the value of the company, the price of its securities may decline or may not approach the value that the investment adviser anticipates.

●

Quantitative Models Risk Aperio uses quantitative analyses and models as part of its investment process, and any imperfections, errors, or limitations in those analyses and models could affect the Fund's performance. By necessity, these analyses and models make simplifying assumptions that limit their efficacy. Models that appear to explain prior market data can fail to predict future market events. Further, the data used in models may be inaccurate or subjective and may not include the most recent information about a company or a security. The Fund also runs the risk that the Adviser's or Aperio's assessment of an investment or its attributes may be wrong or that deficiencies in their internal systems or controls will cause losses for the Fund or impair Fund operations.

●

Information Technology Sector Risk Prices of technology companies' securities historically have been more volatile than those of many other securities, especially over the short term. Technology companies are subject to significant competitive pressures, such as aggressive pricing of their products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company's business, results of operations, and financial condition. Many technology companies have limited operating histories.

●

Emerging Markets Risk Investments in emerging markets are likely to have greater exposure to the risks associated with investments in non-U.S. securities generally. Additionally, emerging market countries generally have less mature economies and less developed securities markets with more limited trading activity, are more heavily dependent on international trade and support, have a higher risk of currency devaluation, and may have more volatile inflation rates or longer periods of high inflation than more developed countries.

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

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 Global Opportunities Fund's performance. For the period between the Global Opportunities Fund's commencement of operations on June 27, 2018 through December 31, 2018, the Global Opportunities Fund's portfolio turnover rate was 17% 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 Institutional Class or Investor Class shares of the Global Opportunities Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class or Investor Class shares of the Global Opportunities 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 Opportunities Fund's operating expenses remain the same throughout those periods. The amounts shown reflect the contractual reimbursement noted in the Annual Fund Operating Expenses table for the first year. 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:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Global Opportunities 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 Opportunities Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies that its Adviser or Sub-Adviser believe will benefit from the transition to a more sustainable global economy – the shift away from a depletive economy to one that preserves ecological and societal balance for the benefit of future generations. The Fund seeks to invest in companies with durable business models that are well positioned to benefit from or avoid the risks associated with this transition. Under normal market conditions, the Global Opportunities Fund will invest primarily in equity securities (such as common stocks, preferred stocks and securities convertible into common or preferred stocks) of companies located around the world, including at least 40% of its net assets in securities of companies organized or located outside the United States or doing a substantial amount of business outside the United States, 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 Opportunities Fund will normally have investments in a minimum of three countries other than the United States. The Adviser and Sub-Adviser currently expect that the Fund typically will hold between 35 and 45 securities positions.

The Global Opportunities Fund's Sub-Adviser selects equity securities on a company-by-company basis primarily through the use of fundamental analysis. The Global Opportunities 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 Opportunities Fund may utilize derivatives for hedging and for investment purposes.

It is possible that, due to its investment strategies, the portfolio turnover rate of the Fund may be significant. Portfolio turnover is not a principal consideration in investment decisions for the Fund, and the Fund is not subject to any limit on the frequency with which portfolio securities may be purchased or sold.

The Global Opportunities Fund seeks to invest in companies with sustainable competitive advantages, track records of consistent returns on investment, and where the Fund's Sub-Adviser believes a company's attractive, bottom-up financial characteristics and long-term opportunities are not reflected in its share price. In addition, as a result of the Fund's investment strategy, under normal market conditions, the Fund is expected to be fossil fuel-free (not invested in securities of companies that IAM determines are significantly involved in the extraction and/or refining of fossil fuels).

Risk Narrative [Text Block]

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 also may be 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.

●

Emerging Markets Risk Investments in emerging markets are likely to have greater exposure to the risks associated with investments in non-U.S. securities generally. Additionally, emerging market countries generally have less mature economies and less developed securities markets with more limited trading activity, are more heavily dependent on international trade and support, have a higher risk of currency devaluation, and may have more volatile inflation rates or longer periods of high inflation than more developed countries.

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

The foregoing descriptions are only summaries. Please see "About the Funds—Principal Risks" on page 116 for more detailed descriptions of the foregoing risks.

Risk Narrative [Text Block]

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.

●

Equity Securities Risk The market price of equity securities may fluctuate significantly, rapidly and unpredictably, causing the Fund to experience losses. The prices of equity securities generally are more volatile than the prices of debt securities.

●

Investment Approach Risk The Fund does not attempt to outperform the MSCI EAFE ESG Leaders Index or take defensive positions in declining markets. Accordingly, the Fund's performance would likely be adversely affected by a decline in the MSCI EAFE ESG Leaders Index.

●

Concentration Risk A fund that concentrates in a single industry or group of industries may be more susceptible to an economic, market, political or regulatory occurrence affecting that specific industry or group of industries. If the MSCI EAFE ESG Leaders Index concentrates in an industry or group of industries, the Fund will concentrate in the same industry or group of industries.

●

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.

●

Asian/Pacific Investment Risk Certain Asia and Pacific region economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Asia and Pacific region economies generally are dependent on the economies of Europe and the United States, especially with respect to agricultural products and natural resources. Political and social instability and deteriorating economic conditions may result in significant downturns and increased volatility in many Asia and Pacific region economies. Portions of the Asia and Pacific region have historically been prone to natural disasters such as tsunamis and droughts and the region is economically sensitive to environmental events. Any such event could have a significant adverse effect on Asia and Pacific region economies. The Australian and New Zealand economies, in particular, are dependent on exports from the agricultural and mining sectors, which make those economies particularly susceptible to fluctuations in the commodities markets. Australian and New Zealand economies are also increasingly dependent on their growing service industries. Economic events in any one country can have a significant economic effect on the entire Asia and Pacific region.

●

European Investment Risk The Economic and Monetary Union of the European Union ("EU") requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect EU member countries, as well as other European countries. The June 2016 vote in the United Kingdom ("UK") calling for the exit of the UK from EU membership (referred to as Brexit) may cause uncertainty and thus adversely impact the financial results and operations of various European companies and economies. The effects of Brexit will depend on agreements the UK negotiates to retain access to EU markets either during a transitional period or more permanently. Brexit could lead to legal and tax uncertainty and potentially divergent national laws and regulations as the UK determines which EU laws to replace or replicate. Brexit has already caused significant volatility in global financial markets and uncertainty about the integrity and functioning of the EU, both of which may persist for an extended period of time. Although it is not possible to predict the full effect of Brexit, Brexit could have a significant adverse impact on UK, European and global macroeconomic conditions and could lead to prolonged political, legal, regulatory, tax and economic uncertainty. An economic recession in the UK, or in an EU member country, decreasing imports or exports, changes in governmental regulations on trade and changes in the exchange rate of the euro may have a significant adverse effect on the economies of EU members and their trading partners, including non-member European countries. Additionally, Eastern European markets remain relatively undeveloped and may be particularly sensitive to political and economic developments.

●

Currency Risk The U.S. dollar value of your investment in the Fund may go down if the value of the local currency of the non-U.S. markets in which the Fund invests depreciates against the U.S. dollar.

●

Issuer Risk The value of a security may fluctuate due to factors affecting only the entity that issued the security.

●

Non-Correlation Risk The performance of the EAFE ESG Index Fund and of the MSCI EAFE ESG Leaders Index may vary somewhat for a variety of reasons. For example, the EAFE ESG Index Fund incurs operating expenses and portfolio transaction costs not incurred by the MSCI EAFE ESG Leaders Index. In addition, the EAFE ESG Index Fund may not be able to be fully invested in the component securities of the MSCI EAFE ESG Leaders Index. Any use of sampling techniques may affect the EAFE ESG Index Fund's ability to achieve close correlation with the MSCI EAFE ESG Leaders Index.

●

Management Risk At any time that the Fund employs a representative sampling strategy, investment decisions made by IAM and the Fund's portfolio manager may cause the Fund to underperform the MSCI EAFE ESG Leaders Index.

●

Medium-Sized Company Risk Securities of 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.

●

Financial Services Sector Risk Companies in the financial services sector are subject to the risk of regulatory change, decreased liquidity in credit markets and unstable interest rates. Such companies may have concentrated portfolios, such as a high level of loans to real estate developers, which makes them vulnerable to economic conditions that affect that industry. Performance of such companies may be affected by competitive pressures and exposure to investments or agreements that, under certain circumstances, may lead to losses. Companies in the financial services sector are subject to extensive governmental regulation that may limit the amount and types of loans and other financial commitments they can make, and interest rates and fees that they may charge. In addition, profitability of such companies is largely dependent upon the availability and the cost of capital.

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

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in Institutional Class or Investor Class shares of the Core Bond Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class or Investor Class shares of the Core Bond 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 Core Bond 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:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Core Bond 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 Core Bond Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds, which include debt obligations such as mortgage-related securities, securities issued by the United States government or its agencies and instrumentalities, municipal bonds, corporate bonds and high-impact bonds (which provide financing to support solutions to global sustainability challenges) across the spectrum of issuers, each of which is, at the time of purchase, rated at least investment grade (rated BBB- or higher by Standard & Poor's Ratings Group or Baa3 or higher by Moody's Investors Service) or unrated and determined by the Adviser to be of comparable quality. The Fund also may have a small allocation of higher-rated high yield bonds, also commonly known as "junk bonds" (rated B or lower by Standard & Poor's Ratings Group or Moody's Investors Service). Although the Fund is not constrained with respect to duration, it seeks to maintain an average duration within .50 years of the duration of the Bloomberg Barclays U.S. Aggregate Bond Index, which had a duration of 5.77 years as of December 31, 2018.

In determining which securities to buy for the Core Bond Fund, the portfolio manager seeks to determine the most attractive asset class and establish if each security's return is appropriate for its level of risk. In making these determinations, the portfolio manager generally performs a relative value analysis at the asset class level.

The Core Bond Fund may invest up to 45% of its assets in securities of non-U.S. issuers, including emerging market investments.

The Core Bond Fund may utilize derivatives, including but not limited to repurchase agreements, foreign currency exchange contracts, options and futures contracts, for hedging and for investment purposes.

It is possible that, due to its investment strategies, the portfolio turnover rate of the Core Bond Fund may be significant. Portfolio turnover is not a principal consideration in investment decisions for the Fund, and the Fund is not subject to any limit on the frequency with which portfolio securities may be purchased or sold.

Risk Narrative [Text Block]

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 also may be 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. For example, if a debt security has a duration of four years, a 1% increase in interest rates could be expected to result in a 4% decrease in the value of the security.

●

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. Liquidity risk also may refer to the risk that the Fund could not meet requests to redeem shares of the Fund without significant dilution of remaining investors' interests in the Fund. 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.

●

Management Risk The Fund is actively managed. The investment techniques and decisions of the investment adviser and the Fund's portfolio manager(s) 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.

●

Emerging Markets Risk Investments in emerging markets are likely to have greater exposure to the risks associated with investments in non-U.S. securities generally. Additionally, emerging market countries generally have less mature economies and less developed securities markets with more limited trading activity, are more heavily dependent on international trade and support, have a higher risk of currency devaluation, and may have more volatile inflation rates or longer periods of high inflation than more developed countries.

●

High Yield Securities Risk High yield securities ("junk bonds") are considered predominately speculative with respect to the issuer's continuing ability to make principal and interest payments when due. Investments in such securities tend to increase the Fund's exposure to interest rate risk, credit risk and liquidity risk.

●

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.

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

Under normal market conditions, the High Yield Bond Fund invests at least 80% of its assets (plus any borrowings for investment purposes) in high-yield, fixed income securities (such as bonds, notes or debentures) that are rated below BBB- by Standard & Poor's Ratings Group or below Baa3 by Moody's Investors Service, similarly rated by another major rating service, or unrated and determined by the High Yield Bond Fund's investment adviser to be of comparable quality. These fixed income securities are commonly referred to as "junk bonds." The Fund may invest in securities of any maturity. The High Yield Bond Fund may, on a short-term basis pending longer term investment, invest in exchange traded funds that invest primarily in high-yield securities. The High Yield Bond Fund treats these short-term investments as high-yield, fixed income securities for purposes of its 80% policy.

In determining which securities to buy for the High Yield Bond Fund, the portfolio managers seek to establish if each security's return is appropriate for its level of risk.

In making this determination, the portfolio managers generally perform fundamental credit analysis. The High Yield Bond Fund may invest up to 40% of its assets in securities of non-U.S. issuers, including investments in emerging markets.

The High Yield Bond Fund may utilize derivatives for hedging and for investment purposes, and may invest in credit default swaps on indices of high-yield securities on a short-term basis (generally less than 90 days) pending longer term investment.

It is possible that, due to its investment strategies, the portfolio turnover rate of the High Yield Bond Fund may be significant. Portfolio turnover is not a principal consideration in investment decisions for the Fund, and the Fund is not subject to any limit on the frequency with which portfolio securities may be purchased or sold.

The Balanced Fund follows a multi-asset environmental, social and governance (ESG) strategy that invests in underlying funds that integrate ESG analysis into security selection and portfolio construction.

The Balanced Fund uses a team approach to allocate among multiple underlying funds managed by the Adviser ("Underlying Funds") in order to seek to achieve its investment objectives. The Adviser will allocate the Fund's assets among Underlying Funds in its sole discretion. Under normal market conditions, the Balanced Fund expects to invest (indirectly through the use of Underlying Funds) approximately 50–75% of its assets in equity securities (such as common stocks, preferred stocks and securities convertible into common or preferred stocks) and 25–50% of its assets in debt securities (including but not limited to debt securities convertible into equity securities).

The Balanced Fund's multi-asset ESG strategy is designed to achieve lower volatility by combining complementary investment approaches. Allocation of assets among Underlying Funds is based on such factors as prudent diversification principles, the Adviser's general market outlooks (both domestic and global), historical performance, valuations and other economic factors. The Adviser may periodically adjust asset allocations to favor those Underlying Funds that it believes will provide the most favorable outlook for achieving the Fund's investment objective. The Adviser may periodically adjust the Fund's asset allocations at any time without notice to shareholders and without shareholder approval.

With respect to the fixed income portion of the portfolio, the Balanced Fund may, through Underlying Funds, be indirectly invested in (i) securities issued by the U.S. government, its agencies and instrumentalities, (ii) corporate bonds and asset backed securities of all types (including mortgage-backed securities), and (iii) securities of foreign issuers. The Fund may indirectly hold fixed income securities of any rating, including junk bonds (e.g., securities rated lower than BBB- by Standard & Poor's Ratings Group or Baa3 by Moody's Investors Service or unrated securities of comparable quality as determined by the Adviser), though it is not currently anticipated that the Fund will indirectly hold more than 20% of its assets in junk bonds. The Fund may invest in securities of any maturity. The Underlying Funds to be utilized for the fixed income portion of the Fund may include, but are not limited to, Pax Core Bond Fund and Pax High Yield Bond Fund.

With respect to the equity portion of its investment portfolio, the Fund may, through Underlying Funds, be indirectly invested in securities of companies with any market capitalization. The Underlying Funds to be utilized for the equity portion of the Fund may include, but are not limited to, Pax Large Cap Fund, Pax ESG Beta Dividend Fund, Pax Mid Cap Fund, Pax Global Environmental Markets Fund, Pax Ellevate Global Women's Leadership Fund and Pax MSCI EAFE ESG Leaders Index Fund.

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, through Underlying Funds, indirectly 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 indirectly 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. The Balanced Fund may also, for cash management purposes, invest in unaffiliated exchange-traded funds ("ETFs") pending reinvestment of such assets in Underlying Funds.

Risk Narrative [Text Block]

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.

●

Equity Securities Risk The market price of equity securities may fluctuate significantly, rapidly and unpredictably, causing the Fund to experience losses. The prices of equity securities generally are more volatile than the prices of debt securities.

●

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 also may be 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. For example, if a debt security has a duration of four years, a 1% increase in interest rates could be expected to result in a 4% decrease in the value of the security.

●

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. Liquidity risk also may refer to the risk that the Fund could not meet requests to redeem shares of the Fund without significant dilution of remaining investors' interests in the Fund. 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.

●

Emerging Markets Securities Risk Emerging market securities are likely to have greater exposure to Non-U.S. Securities Risk. In addition, emerging markets generally have less developed economies and securities markets, are more prone to rapid social, political and economic changes, have a higher risk of currency devaluation and have more volatile inflation rates than more developed countries.

●

Underlying Funds and ETFs Risk Investments in shares of Underlying Funds and ETFs are subject to the fees, expenses and risks of those Underlying Funds or ETFs. If an Underlying Fund or ETF seeks to track the performance of an index, the value of the Fund's investment in such Underlying Fund or ETF also would fluctuate with the value of the index. The Adviser has a conflict of interest in selecting investments for the Fund because the Underlying Funds, unlike unaffiliated ETFs, pay fees to the Adviser, and the fees paid to it by some Underlying Funds are higher than the fees paid by other Underlying Funds.

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