| 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 fiscal year ended July 31, 2011, the portfolio turnover rate of the Fund was 42% of the average value of its portfolio. |

The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (reflecting the contractual fee waiver). Although your actual costs may be higher or lower, based on these assumptions your costs would be: |
||||||||
| Strategy [Heading] | rr_StrategyHeading | The Fund's Principal Investment Strategies | ||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal circumstances, the Fund invests at least 80% of its assets in income-producing securities such as debt securities, common stocks, preferred stocks and common and preferred shares of closed-end investment companies (also known as "closed-end funds") having portfolios consisting primarily of income-producing securities. Debt securities in which the Fund may invest include, but are not limited to, U.S. government agency securities and variable or floating-rate instruments. Certain of the debt securities and preferred stocks in which the Fund may invest may be convertible into common shares. The Fund normally invests in equity securities of companies with a market capitalization of approximately $400 million to $700 billion. The Fund's sub-advisor, Fifth Third Asset Management, Inc. ("FTAM"), seeks to provide value by investing in asset classes that appear to be attractive based on their risks and in companies with cheap (e.g., attractive price to cash flow ratio) cash flows in each asset class. FTAM may invest in debt securities of any maturity, and will increase its investment in short term debt securities during periods when it believes interest rates will rise and will increase its investment in long-term debt securities during periods when it believes interest rates will decline. FTAM seeks to maximize risk-adjusted returns through fundamental research, quantitative modeling, and capital structure analysis. In performing this research, modeling and analysis, FTAM evaluates companies based on such factors as sales, assets, earnings, markets, and management, and FTAM searches for companies with favorable debt-to-equity ratios. The Fund seeks returns by investing across a broader array of investments than traditional investment grade fixed income funds, and FTAM believes that a low correlation between various asset classes leads to stability of expected returns. In selecting corporate debt securities for the Fund, FTAM intends to invest principally in securities rated BBB or better by Standard & Poor's (or the equivalent using Moody's), but may invest in securities rated as low as BB, B, CCC or CC or unrated securities when these investments are believed by FTAM to be sound and consistent with an objective of reasonable risk. The Fund will not invest more than 20% of its assets in (i) securities rated BB or lower by Standard & Poor's and/or (ii) unrated securities which, in the opinion of FTAM, are of quality comparable to those rated BB or lower. Securities rated lower than BBB by Standard & Poor's, sometimes referred to as "junk bonds," are lower-rated securities and have speculative characteristics. The Fund may invest in any diversified closed-end income fund as long as the Fund's total portfolio maintains no more than 20% of its assets in securities rated BB or lower. The Fund may consider closed-end funds as a "pass through" security, and will look at the composition of the underlying portfolio. Therefore, the Fund may invest in any single closed-end fund even if more than 20% of the closed-end fund's assets are invested in securities rated BB or lower. The closed-end funds in which the Fund may invest may in turn invest in debt and equity securities of United States or foreign issuers. The Fund may enter into foreign currency contracts to settle planned purchases or sales of securities or to protect against a possible loss resulting from the adverse change in the relationship between the U.S. dollar and a foreign currency involved in an underlying transaction. The Fund may enter into futures contracts to gain exposure to, or hedge against changes in the value of interest rates or foreign currencies. The Fund may enter into interest rate, total return, credit default, and other forms of swap agreements to manage its exposure to interest rates and credit risk. The Fund may utilize call and put options to gain investment exposure or to hedge against portfolio volatility. FTAM may consider selling a portfolio holding when: deterioration in a company's strategic position, growth prospects, or financial reporting is detected; an individual security comprises too large a position in the portfolio; a company with declining financial fundamentals has risk volatility of more than one standard deviation in FTAM's proprietary credit risk model; a company's valuations are no longer attractive; or a better opportunity arises. |

| Risk [Heading] | rr_RiskHeading | The Principal Risks | ||||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | The Fund's share price will fluctuate. You could lose money on your investment in the Fund, and the Fund could also return less than other investments. The Fund is subject to the principal risks listed below. Closed-End Fund Risk: The risks of investment in other investment companies typically reflect the risk of the types of securities in which the investment companies invest. The value of the shares of closed-end investment companies may be lower than the value of the portfolio securities held by the closed-end investment company. When the Fund invests in another investment company, shareholders of the Fund bear their proportionate share of the other investment company's fees and expenses as well as its share of the Fund's fees and expenses. There may also not be an active trading market available for shares of some closed-end funds. Additionally, trading of closed-end fund shares may be halted or delisted by the listing exchange. Convertible Securities Risk: Convertible securities are subject to the risks of both debt securities and equity securities. The values of convertible securities tend to decline as interest rates rise and, due to the conversion feature, tend to vary with fluctuations in the market value of the underlying security. Credit Risk: An issuer may be unable to make timely payments of either principal or interest. This may cause the issuer's securities to decline in value. Credit risk is particularly relevant to those portfolios that invest a significant amount of their assets in junk bonds or lower-rated securities. Debt Securities Risk: The prices of the Fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Derivatives Risk: Derivatives may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund's original investment. Use of derivatives may increase the amount and affect the timing and character of taxes payable by shareholders. When a derivative is used as a hedge against an opposite position that the Fund also holds, any loss generated by the derivative should be substantially offset by gains on the hedged investment, and vice versa. Hedges are sometimes subject to imperfect matching between the derivative and underlying security, and there can be no assurance that the Fund's hedging transactions will be effective. Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may suffer a decline in response to such developments which could result in a decline in the value of the Fund's shares. Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may happen separately from, or in response to, events that do not otherwise affect the value of the security in the issuer's home country. There is a risk that foreign securities may not be subject to accounting standards or governmental supervision comparable to U.S. companies and that less public information about their operations may exist. There is risk associated with the clearance and settlement procedures in non-U.S. markets, which may be unable to keep pace with the volume of securities transactions and may cause delays. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Over-the-counter securities may also be less liquid than exchange-traded securities. Forward Currency Exchange Contract Risk: A forward foreign currency exchange contract is an agreement to buy or sell a specific currency at a future date and at a price set at the time of the contract. Forward foreign currency exchange contracts may reduce the risk of loss from a change in value of a currency, but they also limit any potential gains, do not protect against fluctuations in the value of the underlying position and are subject to counterparty risk. Futures Contracts Risk: The risks associated with futures include: the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund's position and the risk that the counterparty to the transaction will not meet its obligations. Interest Rate Risk: As interest rates rise, the value of fixed income securities the Fund owns will be likely to decrease. Longer-term securities are generally more volatile, so the longer the average maturity or duration of these securities, the greater their price risk. Duration is a measure of the expected life, taking into account any prepayment or call features of the security, of a fixed income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the change in the value of a fixed income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed income security becomes due for payment of principal. Management Risk: The value of your investment may decrease if the sub-advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect. Market Risk: Market risk is the risk that the market value of a security may fluctuate, sometimes rapidly and unpredictably. Non-Investment Grade Debt Securities Risk: Non-investment grade debt securities are sometimes referred to as "junk bonds" and are considered speculative with respect to their issuers' ability to make payments of interest and principal. There is a high risk that the Fund could suffer a loss from investments in non-investment grade debt securities caused by the default of an issuer of such securities. Part of the reason for this high risk is that, in the event of a default or bankruptcy, holders of non-investment grade debt securities generally will not receive payments until the holders of all other debt have been paid. In addition, the market for non-investment grade debt securities has, in the past, had more frequent and larger price changes than the markets for other securities. Non-investment grade debt securities can also be more difficult to sell for good value. Successful investment in non-investment grade debt securities involves greater investment risk and is highly dependent on the sub-advisor's credit analysis and market analysis. Options Risk: Options trading is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The value of options can be highly volatile, and their use can result in loss if the sub-advisor is incorrect in its expectation of price fluctuations. The successful use of options for hedging purposes also depends in part on the ability of the sub-advisor to predict future price fluctuations and the degree of correlation between the options and securities markets. When options are purchased over the counter, the Fund bears the risk that the counter-party that wrote the option will be unable or unwilling to perform its obligations under the option contract. Such options may also be illiquid, and in such cases, the Fund may have difficulty closing out its position. Preferred Stock Risk: Preferred stock represents an equity or ownership interest in an issuer that pays dividends at a specified rate and that has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of preferred stocks to decline. Preferred stock may have mandatory sinking fund provisions, as well as provisions allowing the stock to be called or redeemed prior to its maturity, which can have a negative impact on the stock's price when interest rates decline. Prepayment Risk: The risk that a debt security may be paid off and proceeds invested earlier than anticipated. Prepayment risk is more prevalent during periods of falling interest rates. Swap Agreements Risk: The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. Swap agreements also may be considered to be illiquid. In addition, the Fund may enter into swap agreements that involve a limited number of counterparties, which may increase the Fund's exposure to credit risk. Further, there is a risk that no suitable counterparties are willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment goal. Value Investing Risk: A value-oriented investment approach is subject to the risk that a security believed to be undervalued does not appreciate in value as anticipated or experiences a decline in value. As with any mutual fund, there is no guarantee that the Fund will achieve its investment goal. You can find more information about the Fund's investments and risks under the "Investment Strategies and Risks" section of the Fund's Prospectus. |

| 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 fiscal year ended July 31, 2011, the portfolio turnover rate of the Fund was 131% of the average value of its portfolio. |

The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (reflecting the contractual fee waiver). Although your actual costs may be higher or lower, based on these assumptions your costs would be: |

| Strategy [Heading] | rr_StrategyHeading | The Fund's Principal Investment Strategies | ||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal circumstances, the Fund primarily invests its assets in equity securities of non-U.S. issuers. Equity securities include common and preferred stocks. The Fund allocates its assets to securities of issuers located in both developed and emerging markets. The companies whose securities are represented in the Fund's portfolio are located in at least three countries other than the U.S. The Fund may invest in companies of any size in seeking to achieve its investment goal. The Fund's sub-advisor, Barrow, Hanley, Mewhinney & Strauss, LLC ("Barrow Hanley"), uses traditional methods of stock selection -- research and analysis -- to identify securities it believes are undervalued. Barrow Hanley seeks to invest in companies that have (1) price to earnings and price to book ratios below the market, (2) enterprise value/free cash flow ratios at or below the market and (3) dividend yields above the market. For purposes of the preceding sentence, the companies comprising the MSCI EAFE Index constitute the market. Barrow Hanley's investment management approach may be described as traditional value with a focus on income from dividends because it generally focuses on companies which are out of favor with other investors due to internal or external challenges judged to be short-term in nature. Barrow Hanley's process seeks to identify the reasons for a temporary undervaluation of a company's shares and believes that value to the Fund can be added through individual stock selection. Barrow Hanley utilizes risk management tools in an effort to keep the Fund from becoming over-exposed to particular market segments. Barrow Hanley is a "bottom-up" value manager meaning it analyzes the fundamentals of companies one at a time rather than focusing on broader market themes. Barrow Hanley generally considers selling a security when, in Barrow Hanley's opinion, the security reaches fair value estimate, when earnings forecasts do not appear to justify the current price, when there has been or there is an expectation of an adverse change in the company's fundamentals, or when other investment opportunities appear more attractive. The Fund may engage in frequent and active trading as part of its principal investment strategy. |
||||||||
| Risk [Heading] | rr_RiskHeading | The Principal Risks | ||||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | The Fund's share price will fluctuate. You could lose money on your investment in the Fund, and the Fund could also return less than other investments. The Fund is subject to the principal risks listed below. Emerging Markets Risk: Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. As a result, there will tend to be an increased risk of price volatility associated with the Fund's investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar. Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may suffer a decline in response to such developments which could result in a decline in the value of the Fund's shares. Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may happen separately from, or in response to, events that do not otherwise affect the value of the security in the issuer's home country. There is a risk that foreign securities may not be subject to accounting standards or governmental supervision comparable to U.S. companies and that less public information about their operations may exist. There is risk associated with the clearance and settlement procedures in non-U.S. markets, which may be unable to keep pace with the volume of securities transactions and may cause delays. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Over-the-counter securities may also be less liquid than exchange-traded securities. Large Cap Risk: Large cap risk is the risk that stocks of larger companies may underperform relative to those of small and mid-sized companies. Large cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. Management Risk: The value of your investment may decrease if the sub-advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect. Market Risk: Market risk is the risk that the market value of a security may fluctuate, sometimes rapidly and unpredictably. Mid Cap Risk: The Fund is subject to the risk that medium capitalization stocks may underperform other types of stocks or the equity markets as a whole. Stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market. Portfolio Turnover Risk: Frequent and active trading may result in greater expenses to the Fund, which may lower the Fund's performance and may generate more taxable short-term gains for shareholders. Small Cap Risk: The Fund is subject to the risk that small capitalization stocks may underperform other types of stocks or the equity markets as a whole. Small cap stock risk is the risk that stocks of smaller companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group. In addition, small cap stocks typically are traded in lower volume, and their issuers typically are subject to greater degrees of changes in their earnings and prospects. Value Investing Risk: A value-oriented investment approach is subject to the risk that a security believed to be undervalued does not appreciate in value as anticipated or experiences a decline in value. As with any mutual fund, there is no guarantee that the Fund will achieve its investment goal. You can find more information about the Fund's investments and risks under the "Investment Strategies and Risks" section of the Fund's Prospectus. |
