Risk/Return [Heading]	rr_RiskReturnHeading	Federated Max-Cap Index Fund (the "Fund")
Objective [Heading]	rr_ObjectiveHeading	RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund's investment objective is to provide investment results that generally correspond to the aggregate price and performance of publicly traded common stocks comprising the Standard & Poor's 500.
Expense [Heading]	rr_ExpenseHeading	RISK/RETURN SUMMARY: FEES AND EXPENSES
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold Class C Shares (C), Class R Shares (R), Institutional Shares (IS) and Service Shares (SS) of the Fund. More information about these and other discounts is available from your financial professional, in the "What Do Shares Cost?" section of the Prospectus on page 10 and in "Appendix B" to this Prospectus. If you purchase the Fund's IS shares through a broker acting as an agent on behalf of its customers, you may be required to pay a commission to such broker; such commissions, if any, are not reflected in the Example below.

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
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 31% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 for the time periods indicated and then redeem all of your Shares at the end of those periods. Expenses assuming no redemption are also shown. The Example also assumes that your investment has a 5% return each year and that operating expenses are as shown in the table above and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE What are the Fund's Main Investment Strategies?
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund normally invests its assets primarily in common stocks included in the Standard & Poor's 500 Index ("Index"). The Index is a broad-based market index that measures the performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries. Under normal circumstances, the Manager will also use enhanced management techniques as further described in the Prospectus in an attempt to improve the performance of its portfolio relative to the Index to compensate for Fund expenses and tracking error. The Manager's principal enhanced technique will be to slightly over or under-weight positions in securities within the Index based upon the Manager's quantitative analysis of the securities. The Fund may invest in derivative contracts (such as, for example, futures contracts, option contracts and swap contracts), hybrid instruments or convertible securities to implement its investment strategies. The Fund may use derivative contracts or hybrid instruments to increase or decrease the portfolio's exposure to the investment(s) underlying the derivative or hybrid instruments in an attempt to benefit from changes in the value of the underlying investment(s), to realize gains from trading a derivative contract or to hedge against potential losses. There can be no assurances that the Fund's use of derivative contracts or hybrid instruments will work as intended. The Fund will invest its net assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in Index investments. The Fund will notify shareholders of any changes in its investment policies that would enable the Fund to normally invest less than 80% of its net assets (plus any borrowings for investment purposes) in Index investments. The Fund's Manager has received an exemptive order from the SEC to permit the Trust and the Board of Trustees (the "Board") to appoint and replace subadvisers for the Fund and to enter into and amend the Fund's subadvisory agreements without further shareholder approval.
Risk [Heading]	rr_RiskHeading	What are the Main Risks of Investing in the Fund?
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include: Stock Market Risk. The value of equity securities in the Fund's portfolio will fluctuate and, as a result, the Fund's Share price may decline suddenly or over a sustained period of time. Information publicly available about a company, whether from the company's financial statements or other disclosures or from third parties, or information available to some but not all market participants, can affect the price of a company's shares in the market. Among other factors, equity securities may decline in value because of an increase in interest rates or changes in the stock market. Recent and potential future changes in industry and/or economic trends, as well as changes in monetary policy made by central banks and/or their governments, also can affect the level of interest rates and contribute to the development of or increase in volatility, illiquidity, shareholder redemptions and other adverse effects (such as a decline in a company's stock price), which could negatively impact the Fund's performance.   Sector Risk. Because the Fund may allocate relatively more assets to certain industry sectors than others, the Fund's performance may be more susceptible to any developments which affect those sectors emphasized by the Fund. Leverage Risk. Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund's risk of loss and potential for gain. Liquidity Risk. Liquidity risk refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. If this happens, the Fund will be required to continue to hold the security or keep the position open, and the Fund could incur losses. Over-the-counter (OTC) derivative contracts generally carry greater liquidity risk than exchange-traded contracts. Risk of Investing in Derivative Contracts and Hybrid Instruments. Derivative contracts and hybrid instruments involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts and instruments include valuation and tax issues, increased potential for losses and/or costs to the Fund, and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts and hybrid instruments may also involve other risks described in this Prospectus, such as stock market, credit, liquidity and leverage risks. Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. Risk Related to the Economy. The value of the Fund's portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Economic, political and financial conditions, or industry or economic trends and developments may, from time to time, and for varying periods of time, cause the Fund to experience volatility, illiquidity, shareholder redemptions, or other potentially adverse effects. Quantitative Modeling Risk. The Fund employs quantitative models as a management technique. These models examine multiple factors using large data sets. The results generated by quantitative analysis may perform differently than expected and may negatively affect Fund performance. Technology Risk. The Manager uses various technologies in managing the Fund, consistent with its investment objective and strategy described in this Prospectus. For example, proprietary and third party data and systems are utilized to support decision making for the Fund.  Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance. The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

[1] The Manager and certain of its affiliates on their own initiative have agreed to waive certain amounts of their respective fees and/or reimburse expenses. Total annual fund operating expenses (excluding acquired fund fees and expenses, interest expense, extraordinary expenses, line of credit expenses and proxy-related expenses paid by the Fund, if any) paid by the Fund's C, R, IS and SS classes (after the voluntary waivers and/or reimbursements) will not exceed 1.43%, 1.10%, 0.35% and 0.65% (the "Fee Limit"), respectively, up to but not including the later of (the "Termination Date"): (a) January 1, 2019; or (b) the date of the Fund's next effective Prospectus. While the Manager and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Trustees.

[2] The Fund may incur or charge certain service fees (shareholder services/account administration fees) on its IS class of up to a maximum amount of 0.25%. No such fees are currently incurred or charged by the IS class of the Fund. The IS class of the Fund will not incur or charge such fees until such time as approved by the Fund's Board of Trustees (the "Trustees").
