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 its most recent fiscal year, the Fund had a portfolio turnover rate of 28% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategy.
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies with small market capitalizations. For purposes of the 80% policy, net assets include any borrowings for investment purposes. In constructing a portfolio for the Fund, the Fund's subadviser, Netols Asset Management, Inc. ("Netols"), selects stocks it believes are undervalued and exhibit potential "change factor" characteristics. Netols defines a small capitalization company as any company with a market capitalization no larger than the largest company included in the Russell 2000® Value Index at the time of initial investment. As of September 30, 2012, the largest market capitalization of a company in the Russell 2000® Value Index was $3.8 billion and the weighted average market capitalization was $1.1 billion.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks.
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Market Risks. The Fund's investments are subject to market risk, which may cause the value of the Fund's investments to decline. If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money. U.S. and international markets have experienced extreme volatility, reduced liquidity, credit downgrades, increased likelihood of default and valuation difficulties in recent years. Equity Securities Risks. Common stocks and other equity securities held by the Fund will fluctuate in value based on the earnings of the company and on general industry and market conditions, leading to fluctuations in the Fund's share price. Stock Selection Risks. The stocks selected for the Fund may decline in value or not increase in value when the stock market in general is rising. Value Investing Risks. Netols invests in companies that it believes are undervalued. Such companies may never increase in price or pay dividends, or may decline even further if the market fails to recognize the company's value. Small Capitalization Company Risks. Securities of companies with small market capitalizations are often more volatile, less liquid and more susceptible to market pressures than larger companies. Management Risks. The Fund is subject to management risk as an actively-managed investment portfolio and depends on the decisions of the portfolio manager to produce the desired results.
Risk Lose Money [Text]	rr_RiskLoseMoney	If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money.
