| 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 Fund's most recent fiscal year, the Fund's portfolio turnover rate was 44% of the average value of its portfolio. |

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same and that all dividends and distributions are reinvested. Your actual costs may be higher or lower. |

| Strategy [Heading] | rr_StrategyHeading | INVESTMENTS, RISKS AND PERFORMANCE
Principal Investment Strategies. |
|||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | We seek investments whose price will increase over time. We normally invest at least 80% of our investable assets in equity and equity-related securities of small, less well-known companies that the investment subadviser believes are relatively undervalued. In deciding which stocks to buy, we use a blend of both value and growth styles. We look for stocks of smaller, less well-known companies in a variety of different industries and sectors that we believe have attractive valuations, and should experience superior earnings growth on an intermediate term basis. "Investable assets" consist of the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. We currently consider small companies to be those with a market capitalization less than the largest market capitalization of the Russell 2500 Index at the time of investment. The market capitalization within the index will vary, but as of October 31, 2011, the median market capitalization was approximately $661 million and the largest company by market capitalization was approximately $8.1 billion. The portfolio is diversified and typically will include stocks representing all of the sectors in the Russell 2500 Index. While we make every effort to achieve our objective, we cannot guarantee success. |

| Risk [Heading] | rr_RiskHeading | Principal Risks of Investing in the Fund. | |||||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.
Recent Market Events. The equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. This financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the investment subadviser. These market conditions may continue or get worse. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be known for some time.
Risk of Increase in Expenses. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Small Company Risk. Small company stocks present above-average risks. This means that when stock prices decline overall, the Fund may decline more than a broad-based securities market index. These companies usually offer a smaller range of products and services than larger companies. They may also have limited financial resources and may lack management depth. As a result, stocks issued by smaller companies tend to be less liquid and fluctuate in value more than the stocks of larger, more established companies.
Equity and Equity-Related Securities Risks. There is the risk that the value of a particular security could go down and you could lose money. In addition to an individual stock losing value, the value of the equity markets or a sector in which the Fund invests could go down. The Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.
The Fund may invest in companies that reinvest their earnings rather than distribute them to shareholders. To the extent the Fund does invest in such companies, the Fund is not likely to receive significant dividend income on its portfolio securities.
Blend Style Risk. The Fund's blend investment style may subject the Fund to risks of both value and growth investing. The portion of the portfolio that makes investments pursuant to a growth strategy may be subject to above-average fluctuations as a result of seeking higher than average capital growth. The portion of the portfolio that makes investments pursuant to a value strategy may be subject to the risk that the market may not recognize a security's intrinsic value for a long time or that a stock judged to be undervalued may actually be appropriately priced. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Therefore, both styles may over time go in and out of favor with the markets. At times when a style is out of favor, that portion of the portfolio may lag the other portion of the portfolio, which may cause the Fund to underperform the market in general, its benchmark and other mutual funds. Growth and value stocks have historically produced similar long-term results, though each category has periods when it outperforms the other. Initial Public Offerings Risk. The Fund may participate in the initial public offering (IPO) market. The volume of IPOs and the levels at which the newly issued stocks trade in the secondary market are affected by the performance of the stock market overall. If IPOs are brought to the market, availability may be limited and if the Fund desires to acquire shares in such an offering, it may not be able to buy any shares at the offering price, or if it is able to buy shares, it may not be able to buy as many shares at the offering price as it would like. The prices of securities involved in IPOs are often subject to greater and more unpredictable price changes than more established stocks. Such unpredictability can have a dramatic impact on the Fund's performance (higher or lower) and any assumptions by investors based on the impacted performance may be unwarranted. In addition, as Fund assets grow, the impact of IPO investments on performance will decline, which could reduce total returns.
Management Risk. Actively managed mutual funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these techniques will produce the desired results. Additionally, the securities selected by the subadviser may underperform the markets in general, the Fund's benchmark and other mutual funds with similar investment objectives. Market Risk. Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Securities markets are volatile. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Regardless of how well an individual investment performs, if financial markets go down, you could lose money.
