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 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 High Yield Bond Fund's performance. During the High Yield Bond Fund's most recent fiscal year, the High Yield Bond Fund's portfolio turnover rate was 74% of the average value of its portfolio.

Expense Example Narrative [Text Block]

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 High Yield Bond 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 High Yield 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 High Yield 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 [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The High Yield 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 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 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.

Risk [Heading]

rr_RiskHeading

Principal 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.

•  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.

•  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.

•  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.

•  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.

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

The foregoing descriptions are only summaries. Please see "About the Funds—Risks" on page 71 for more detailed descriptions of the foregoing risks.

[1] The BofA Merrill Lynch U.S. High Yield-Cash Pay-BB-B (Constrained 2%) Index tracks the performance of BB- and B-rated fixed income securities publicly issued in the major domestic or eurobond markets, with total index allocation to an individual issuer limited to 2%.

[2] Unlike the High Yield Bond Fund, the BofA Merrill Lynch U.S. High Yield-Cash Pay-BB-B (Constrained 2%) Index and the Lipper High Yield Bond Funds Index are not investments, are not professionally managed, have no policy of sustainable investing and (with the exception of the Lipper High Yield Bond Funds Index) do not reflect deductions for fees, expenses or taxes. One cannot invest directly in any index.

[3] The Lipper High Yield Bond Funds Index tracks the results of the 30 largest mutual funds in the Lipper High Yield Bond Funds Average. The Lipper High Yield Bond Funds Average is a total return performance average of mutual funds tracked by Lipper, Inc. that aim at high (relative) current yield from fixed income securities, have no quality or maturity restrictions and tend to invest in lower grade debt issues. The Lipper High Yield Bond Funds Index is not what is typically considered an "index" because it tracks the performance of other mutual funds rather than changes in the value of a group of securities, a securities index or some other traditional economic indicator.

[4] The Fund charges a fee of $10.00 for each wire redemption, subject to change without notice.

[5] The Fund's investment adviser assumed certain expenses during the period; total returns would have been lower had these expenses not been assumed. Total return figures include reinvested dividends and capital gains distributions, and changes in principal value, and, other than for Individual Investor Class shares, do not reflect the taxes that a shareholder might pay on Fund distributions or on the redemption of Fund shares. These figures represent past performance, which is no guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. For more recent month-end performance data, please visit www.paxworld.com or call 800.767.1729.

[6] Inception of Institutional Class shares is June 1, 2004. The performance information shown for Institutional Class shares includes the performance of Individual Investor Class shares for the period prior to Institutional Class inception. Expenses have not been adjusted to reflect the expenses allocable to Institutional Class shares. If such expenses were reflected, the returns would be higher than those shown.

[7] Inception of Class R shares is April 2, 2007. The performance information shown for Class R shares includes the performance of Individual Investor Class shares for the period prior to Class R inception. Expenses have not been adjusted to reflect the expenses allocable to Class R shares. If such expenses were reflected, the returns would be lower than those shown.

[8] This charge applies to investors who purchase $1 million or more of Class A shares without an initial sales charge and redeem them within 18 months of purchase, with certain exceptions. See "Shareholder Guide-Sales Charges."

[9] Inception of Class A shares is May 1, 2013. The performance information shown for Class A shares includes the performance of Individual Investor Class shares, adjusted to reflect the sales charge applicable to Class A shares, for the period prior to Class A inception.
