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 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 110% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund's Sub-Adviser seeks to achieve the Fund's investment objectives by investing primarily in income-producing equity securities (including real estate investment trusts ("REITs")) of U.S. real estate companies. Under normal market conditions, the Fund invests at least 80% of its assets (defined as net assets plus borrowing for investment purposes) in equity securities of companies principally engaged in the U.S. real estate industry. The Fund defines a company as principally engaged in the U.S. real estate industry if at least 50% of the company's revenues or 50% of the market value of the company's assets are related to the ownership, construction, management or sale of U.S. real estate. The Sub-Adviser believes that by investing in equity securities of real estate companies, rather than investing in individual commercial or residential properties, the Fund's returns may be higher because of the benefits of diversification that include the avoidance of excess exposure to property-specific risks such as tenant default, illiquidity, property damage and vacancy. In general, the Sub-Adviser buys securities of issuers that generate above-average cash flow from operations and are trading at an attractive valuation. The Sub-Adviser sells securities when a company no longer meets its selection criteria or there is a sufficiently more attractive company. The Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund. The Fund's Sub-Adviser may engage in active and frequent trading of the Fund's portfolio securities to achieve the Fund's investment objectives.

The Sub-Adviser seeks to outperform other real estate funds using in-house knowledge, research and its understanding of the real estate market. The Sub-Adviser seeks to find favorable real estate investments in the public markets through disciplined analysis by combining bottom-up fundamental research of companies with a research driven top-down asset allocation. Through such analysis, the Sub-Adviser seeks to deliver total return by identifying individual company value and by repositioning the Fund's portfolio to be invested in companies with the best property types and geographic regions based on current real estate market conditions. Additionally, the Sub-Adviser focuses the Fund's securities portfolio on investments that generally provide income and also have the potential for long-term capital appreciation.

The Fund may also engage in securities lending.

Risk [Heading]

Principal Investment Risks:

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. Although the Fund will strive to meet its investment objective, there is no assurance that it will do so. Many factors affect the Fund's net asset value and performance.

Liquidity Risk – Some securities may have few market-makers and low trading volume, which tend to increase transaction costs and may make it impossible for a Fund to dispose of a security position at all or at a price which represents current or fair market value.

Management Risk – The Fund is subject to management risk because it is an actively managed investment portfolio. The Sub-Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its decisions will produce the intended result. The successful use of hedging and risk management techniques may be adversely affected by imperfect correlation between movements in the price of the hedging vehicles and the securities being hedged.

Non-Diversification Risk – As a non-diversified fund, the Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

Portfolio Turnover Risk – A higher portfolio turnover will result in higher transactional and brokerage costs and may result in higher taxes when Fund shares are held in a taxable account.

Real Estate Industry Concentration Risk – By concentrating in a single sector, the Fund carries much greater risk of adverse developments in that sector than a fund that invests in a wide variety of industries. Real estate values rise and fall in response to a variety of factors, including local, regional and national economic conditions, interest rates and tax considerations.

Real Estate Investment Trust Risk – A REIT's performance depends on the types and locations of the rental properties it owns and on how well it manages those properties. A decline in rental income may occur because of extended vacancies, increased competition from other properties, tenants' failure to pay rent or poor management.

Securities Lending Risk – The risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Small and Medium Capitalization Risk – The Fund's investments in smaller and medium-sized companies carry more risks than investments in larger companies. Companies with small and medium size market capitalization often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies.

Stock Market Risk – Stock markets can be volatile. In other words, the prices of stocks can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions. The Fund's investments may decline in value if the stock markets perform poorly.
