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 61% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of mid-capitalization companies, and in derivatives and other instruments that have economic characteristics similar to such securities. The principal type of equity security in which the Fund invests is common stock.       The Fund considers an issuer to be a mid-capitalization issuer if it has a market capitalization, at the time of purchase, within the range of the largest and smallest capitalized issuers included in the Russell Midcap® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of December 31, 2012, the capitalization of issuers in the Russell Midcap® Index ranged from $319.4 million to $21.5 billion.       The Fund may invest up to 25% of its net assets in securities of foreign issuers, which may include securities of issuers located in emerging markets countries, i.e., those that are in the initial stages of their industrial cycles.       The Fund can invest in derivative instruments including forward foreign currency contracts and futures contracts.       The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.       The Fund can use futures contracts, including index futures, to gain exposure to the broad market by equitizing cash and as a hedge against downside risk.       In selecting securities for the Fund, the portfolio managers conduct fundamental research of issuers to gain a thorough understanding of their business prospects, appreciation potential and return on invested capital (ROIC). The process they use to identify potential investments for the Fund includes three phases: financial analysis, business analysis and valuation analysis. Financial analysis evaluates an issuer's capital allocation, and provides vital insight into historical and potential ROIC which is a key indicator of business quality and caliber of management. Business analysis allows the team to determine an issuer's competitive positioning by identifying key drivers of the issuer, understanding industry challenges and evaluating the sustainability of competitive advantages. Both the financial and business analyses serve as a basis to construct valuation models that help estimate an issuer's value. The portfolio managers use three primary valuation techniques: discounted cash flow, traditional valuation multiples and net asset value. At the conclusion of their research process, the portfolio managers will generally invest in an issuer when they have determined it potentially has high or improving ROIC, quality management, a strong competitive position and is trading at an attractive valuation.       The portfolio managers consider selling a security when it exceeds the target price, has not shown a demonstrable improvement in fundamentals or a more compelling investment opportunity exists.       The Fund employs a risk management strategy to help minimize loss of capital and reduce excessive volatility. Pursuant to this strategy, the Fund generally invests a substantial amount of its assets in cash and cash equivalents. As a result, the Fund may not achieve its investment objective.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:       Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.       Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.       Developing/Emerging Markets Securities Risk. The prices of securities issued by foreign companies and governments located in developing/emerging markets countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.       Foreign Securities Risk. The Fund's foreign investments may be affected by changes in a foreign country's exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.       Management Risk. The investment techniques and risk analysis used by the Fund's portfolio managers may not produce the desired results.       Market Risk. The prices of and the income generated by the Fund's securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.       Small- and Mid-Capitalization Risks. Stocks of small- and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small- and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.
