| 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 45% of the average value of its portfolio. |

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be: |

| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund provides global exposure to the real estate securities market, focusing on owners and operators with recurring rental income. Under normal circumstances, the fund invests at least 80% of its assets in equity securities issued by U.S. and non-U.S companies of any capitalization that are principally engaged in the real estate industry, including common stock, preferred stock and other equity securities issued by real estate companies, such as real estate investment trusts (“REITs”) and similar REIT-like entities. The fund, under normal market conditions, will hold at least 40% of its assets in non-U.S. issuers, unless market conditions outside of the U.S. are deemed less favorable by the portfolio manager, in which case the fund would invest at least 30% of its assets in securities of non-U.S. issuers. Additionally, the fund normally invests in real estate-related securities of issuers in developed countries; however it may invest up to 20% of its assets in issuers incorporated in emerging market countries. The fund concentrates its assets in the real estate industry. |
