Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	Portfolio Turnover.
Portfolio Turnover	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 33% of the average value of its portfolio.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategy.
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund normally invests at least 80% of its assets in equity securities of companies with small market capitalizations. 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, 2011, the largest market capitalization of a company in the Russell 2000® Value Index was $2.6 billion and the weighted average market capitalization was $928 million.
Risk, Heading	rr_RiskHeading	Principal Investment Risks.
Risk, Narrative	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. 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. Small Capitalization Risks. The Fund will invest primarily in securities of companies with small market capitalizations, which are often more volatile and less liquid and have a smaller trading market than securities of larger companies. Small capitalization companies are also more susceptible to market pressures than larger companies. 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. Value Investing Risks. Netols invests in stocks that it believes are undervalued. Value stocks may never increase in price or pay dividends, or may decline even further if the market fails to recognize the company's value. 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	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.
