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 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 118% of the average value of its portfolio.

The example below is intended to help you compare the costs of investing in the fund with the costs of investing in other mutual funds.
Expense Example by, Year, Caption [Text] rr_ExpenseExampleByYearCaption The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. 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
Under normal market conditions, the fund invests at least 80% of its net assets in equity securities issued by real estate investment trusts (REITs) and other companies engaged in the real estate industry (collectively, real estate securities). A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry. The portfolio managers consider a company to be engaged in the real estate industry if at least 50% of its revenues or 50% of the market value of its assets at the time the securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate. The portfolio managers look for real estate securities they believe will provide superior returns, focusing on companies with the potential for stock price appreciation, plus sustainable growth of cash flow to investors. The portfolio managers use the following investment techniques to construct the portfolio: 1) top down investment research, 2) property sector research that allows the managers to allocate assets among securities with exposure to different segments of the real estate market, 3) bottom up fundamental stock research, and 4) benchmark sensitive portfolio construction that reflects the property sectors and regions, and the individual weights thereof, of the FTSE EPRA/NAREIT Global Index, part of the FTSE EPRA/NAREIT Global Real Estate Index Series. Of these techniques, the portfolio managers place particular emphasis on property sector research. These techniques also help the portfolio managers sell the stocks of companies whose fundamentals are no longer attractively priced. Because the fund’s investment strategy is concentrated in real estate securities, the fund may hold a relatively small number of security positions compared to other funds that hold securities in a broader range of industries.
The fund invests primarily in equity securities of companies located in developed countries world-wide (including the United States), but may also invest in emerging markets. Under normal market conditions, the fund will invest at least 40% (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 30%) of its assets in securities of issuers located outside the United States. The fund will allocate its assets among at least three different countries (one of which may be the United States). 
The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
•
Real Estate Investing Risk — An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund’s investments may be affected by the value of the real estate owned by the companies in which it invests. To the extent the fund invests in companies that make loans to real estate companies, the fund also may be subject to interest rate risk and credit risk.
•
REITs Risk — Investments in REITs are subject to credit risk and interest rate risk with respect to the loans made by the REITs in which the fund invests. Credit risk is the risk that the borrower will not be able to make interest and principal payments on the loan to the REIT when they are due. Interest rate risk is the risk that a change in the prevailing interest rate will cause the value of the loan portfolio held by the REIT to rise or fall.
•
Concentration Risk — Because the fund concentrates its investments in real estate securities, it may be subject to greater risks and market fluctuations than a portfolio investing in a broader range of industries.
•
Foreign Securities Risk — The fund invests in foreign securities, which can be riskier than investing in U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.
•
Emerging Markets Risk — Investing in securities of companies located in emerging market countries generally is riskier than investing in securities of companies located in foreign developed countries.
•
Currency Risk — Because the fund invests in securities denominated in foreign currencies, the fund is subject to currency risk, meaning that the fund could experience losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.
•
Market Risk — The value of the fund’s shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market.
•
Price Volatility Risk — The value of the fund’s shares may fluctuate significantly in the short term.
•
Redemption Risk — The fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. Selling securities to meet such redemptions may cause the fund to experience a loss, increase the fund’s transaction costs or have tax consequences. To the extent that a large shareholder (including a fund of funds or 529 college savings plan) invests in the fund, the fund may experience relatively large redemptions as such shareholder reallocates its assets.
•
Principal Loss Risk — At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund.
An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Expense Example by, Year, Caption [Text] rr_ExpenseExampleByYearCaption The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the fund invests at least 80% of its net assets in equity securities issued by real estate investment trusts (REITs) and other companies engaged in the real estate industry (collectively, real estate securities). A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry. The portfolio managers consider a company to be engaged in the real estate industry if at least 50% of its revenues or 50% of the market value of its assets at the time the securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate. The portfolio managers look for real estate securities they believe will provide superior returns, focusing on companies with the potential for stock price appreciation, plus sustainable growth of cash flow to investors. The portfolio managers use the following investment techniques to construct the portfolio: 1) top down investment research, 2) property sector research that allows the managers to allocate assets among securities with exposure to different segments of the real estate market, 3) bottom up fundamental stock research, and 4) benchmark sensitive portfolio construction that reflects the property sectors and regions, and the individual weights thereof, of the FTSE EPRA/NAREIT Global Index, part of the FTSE EPRA/NAREIT Global Real Estate Index Series. Of these techniques, the portfolio managers place particular emphasis on property sector research. These techniques also help the portfolio managers sell the stocks of companies whose fundamentals are no longer attractively priced. Because the fund’s investment strategy is concentrated in real estate securities, the fund may hold a relatively small number of security positions compared to other funds that hold securities in a broader range of industries.
The fund invests primarily in equity securities of companies located in developed countries world-wide (including the United States), but may also invest in emerging markets. Under normal market conditions, the fund will invest at least 40% (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 30%) of its assets in securities of issuers located outside the United States. The fund will allocate its assets among at least three different countries (one of which may be the United States).
The fund is not permitted to invest in securities issued by companies assigned the Global Industry Classification Standard (GICS) or the Bloomberg Industry Classification Standard (BICS) for the tobacco industry.
The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
•
Real Estate Investing Risk — An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund’s investments may be affected by the value of the real estate owned by the companies in which it invests. To the extent the fund invests in companies that make loans to real estate companies, the fund also may be subject to interest rate risk and credit risk.
•
REITs Risk — Investments in REITs are subject to credit risk and interest rate risk with respect to the loans made by the REITs in which the fund invests. Credit risk is the risk that the borrower will not be able to make interest and principal payments on the loan to the REIT when they are due. Interest rate risk is the risk that a change in the prevailing interest rate will cause the value of the loan portfolio held by the REIT to rise or fall.
•
Concentration Risk — Because the fund concentrates its investments in real estate securities, it may be subject to greater risks and market fluctuations than a portfolio investing in a broader range of industries.
•
Foreign Securities Risk — The fund invests in foreign securities, which can be riskier than investing in U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.
•
Emerging Markets Risk — Investing in securities of companies located in emerging market countries generally is riskier than investing in securities of companies located in foreign developed countries.
•
Currency Risk — Because the fund invests in securities denominated in foreign currencies, the fund is subject to currency risk, meaning that the fund could experience losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.
•
Market Risk — The value of the fund’s shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market.
•
Price Volatility Risk — The value of the fund’s shares may fluctuate significantly in the short term.
•
Tobacco Exclusion Risk — The fund’s prohibition on tobacco-related investments may cause it to forego profitable investment opportunities.
•
Redemption Risk — The fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. Selling securities to meet such redemptions may cause the fund to experience a loss, increase the fund’s transaction costs or have tax consequences. To the extent that a large shareholder (including a fund of funds) invests in the fund, the fund may experience relatively large redemptions as such shareholder reallocates its assets.
•
Principal Loss Risk — At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund.
An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.
