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 37% of the average value of its portfolio.

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 pursues its investment objective by investing in both equity and fixed-income securities that have high relative income potential. The fund's investment adviser's ("Adviser") process for selecting equity investments attempts to identify mature, mid- to large-cap value companies and securities with high dividend yields that are likely to maintain and increase their dividends. The Adviser selects fixed-income investments that offer high current yields. The Adviser expects that these fixed-income investments will primarily be investment-grade debt issues, domestic noninvestment-grade debt securities (also known as "junk bonds" or "high-yield bonds") and foreign investment-grade and noninvestment-grade fixed-income securities, including emerging market debt securities. The Adviser continuously analyzes a variety of economic and market indicators, considers the expected performance and risks unique to these categories of fixed-income investments, and attempts to strategically allocate among the categories to achieve strong income across changing business cycles. The Adviser does not target an average maturity or duration for the Fund's portfolio and may invest in bonds of any maturity range. The Fund may buy or sell foreign currencies in lieu of or in addition to non-dollar denominated fixed-income securities in order to increase or decrease its exposure to foreign interest rate and/or currency markets. Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association ("Ginnie Mae"). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities. The Fund may use derivative contracts and/or hybrid instruments to implement elements of its investment strategy as more fully described in the Fund's Prospectus.
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. Risk Related to Investing for Value. The Fund generally uses a "value" style of investing, so that the Fund's Share price may lag that of other funds using a different investment style. Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy. Liquidity Risk. Trading opportunities are more limited for fixed-income securities that have not received any credit ratings, have received ratings below investment grade or are not widely held. Trading opportunities are more limited for CMOs that have complex terms or that are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund's performance. Infrequent trading of securities may also lead to an increase in their price volatility. Risk Associated with Noninvestment-Grade Securities. Securities rated below investment grade may be subject to greater interest rate, credit and liquidity risks than investment-grade securities. Risk Related to the Economy. Lower grade bond returns are sensitive to changes in the economy. Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Prepayment Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. Risk of Foreign Investing. Because the Fund may invest in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case. Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in American Depositary Receipts (ADRs) and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case. Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market countries may have relatively unstable governments and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or, in certain instances, reversion to closed market, centrally planned economics. Currency Risk. Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience increased volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holding of such currencies or holding of non-U.S. dollar denominated securities. Eurozone Related Risk. A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries. 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 or the Fund's Statement of Additional Information (SAI), such as stock market, interest rate, credit, currency, liquidity and leverage risks. Exchange-Traded Funds Risk. An investment in an exchange-traded fund (ETF) generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchanged traded) that has the same investment objectives, strategies and policies. Sector Risk. Sector risks is the possibility that a certain sector may underperform other sectors or the market as a whole. Leverage Risk. Leverage risk is created when an investment, which includes, for example, an investment in a derivative contract, 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. Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the United States. Such markets have settlement and clearance procedures that differ from those in the United States. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. Inability to dispose of a portfolio security caused by settlement problems could result in losses to the Fund due to a subsequent decline in value of the portfolio security. In addition, security settlement and clearance procedures in some emerging countries may not fully protect the Fund against loss of its assets. Technology Risk. 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.
Risk Lose Money [Text]	rr_RiskLoseMoney	All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance: Bar Chart and Table Risk/Return Bar Chart
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The Fund is the successor to Federated Capital Income Fund, Inc. (the "Predecessor Fund") pursuant to a reorganization that became effective on May 27, 2003. Prior to that date, the Fund had no investment operations. Accordingly, the performance information and financial information provided in this Prospectus for the periods prior to the reorganization is historical information of the Predecessor Fund. The Predecessor Fund was managed by Passport Research Ltd., using the same personnel as the Fund's Adviser and had the same investment objectives, strategies and policies as the Fund. The performance information shown below will help you analyze the Fund's investment risks in light of its historical returns. The bar chart and performance table below reflect historical performance data for the Fund and are intended to help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's A class total returns on a calendar year-by-year basis. The Average Annual Total Return Table shows returns for each class averaged over the stated periods, and includes comparative performance information. The Fund's performance will fluctuate, and past performance (before and after taxes) is not necessarily an indication of future results.

Bar Chart Closing [Text Block]	rr_BarChartClosingTextBlock	The total returns shown in the bar chart do not reflect the payment of any sales charges or recurring shareholder account fees. If these charges or fees had been included, the returns shown would have been lower. Within the periods shown in the bar chart, the Fund's A class highest quarterly return was 12.45% (quarter ended June 30, 2003). Its lowest quarterly return was (13.51)% (quarter ended December 31, 2008).

Performance Table One Class of after Tax Shown [Text]	rr_PerformanceTableOneClassOfAfterTaxShown	After-tax returns are shown only for A class and after-tax returns for B, C, F and IS classes will differ from those shown for A class.
Performance Table Narrative	rr_PerformanceTableNarrativeTextBlock	The Fund's IS class commenced operations on March 30, 2012. For the period prior to the commencement of operations of the IS class, the performance information shown below is for the A class. The performance of the A class has not been adjusted to reflect the expenses applicable to the IS class since the IS class has a lower expense ratio than the expense ratio of the A class. The performance of the A class has been adjusted to reflect the absence of sales charges applicable to A class and to remove any voluntary waiver of Fund expenses related to the A class that may have occurred during the period prior to the commencement of operations of the IS class. In addition to Return Before Taxes, Return After Taxes is shown for the Fund's A class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for A class and after-tax returns for B, C, F and IS classes will differ from those shown for A class. Actual after-tax returns depend on each investor's personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through a 401(k) plan, an Individual Retirement Account or other tax-advantaged investment plan.

Example

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:

Portfolio Turnover

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 37% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund pursues its investment objective by investing in both equity and fixed-income securities that have high relative income potential. The fund's investment adviser's ("Adviser") process for selecting equity investments attempts to identify mature, mid- to large-cap value companies and securities with high dividend yields that are likely to maintain and increase their dividends. The Adviser selects fixed-income investments that offer high current yields. The Adviser expects that these fixed-income investments will primarily be investment-grade debt issues, domestic noninvestment-grade debt securities (also known as "junk bonds" or "high-yield bonds") and foreign investment-grade and noninvestment-grade fixed-income securities, including emerging market debt securities. The Adviser continuously analyzes a variety of economic and market indicators, considers the expected performance and risks unique to these categories of fixed-income investments, and attempts to strategically allocate among the categories to achieve strong income across changing business cycles. The Adviser does not target an average maturity or duration for the Fund's portfolio and may invest in bonds of any maturity range. The Fund may buy or sell foreign currencies in lieu of or in addition to non-dollar denominated fixed-income securities in order to increase or decrease its exposure to foreign interest rate and/or currency markets.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association ("Ginnie Mae"). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

The Fund may use derivative contracts and/or hybrid instruments to implement elements of its investment strategy as more fully described in the Fund's Prospectus.

What are the Main Risks of Investing in the Fund?

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.

• Risk Related to Investing for Value. The Fund generally uses a "value" style of investing, so that the Fund's Share price may lag that of other funds using a different investment style.

• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

• Liquidity Risk. Trading opportunities are more limited for fixed-income securities that have not received any credit ratings, have received ratings below investment grade or are not widely held. Trading opportunities are more limited for CMOs that have complex terms or that are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund's performance. Infrequent trading of securities may also lead to an increase in their price volatility.

• Risk Associated with Noninvestment-Grade Securities. Securities rated below investment grade may be subject to greater interest rate, credit and liquidity risks than investment-grade securities.

• Risk Related to the Economy. Lower grade bond returns are sensitive to changes in the economy.

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise.

• Prepayment Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities.

• Risk of Foreign Investing. Because the Fund may invest in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case.

• Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in American Depositary Receipts (ADRs) and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.

• Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market countries may have relatively unstable governments and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or, in certain instances, reversion to closed market, centrally planned economics.

• Currency Risk. Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience increased volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holding of such currencies or holding of non-U.S. dollar denominated securities.

• Eurozone Related Risk. A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.

• 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 or the Fund's Statement of Additional Information (SAI), such as stock market, interest rate, credit, currency, liquidity and leverage risks.

• Exchange-Traded Funds Risk. An investment in an exchange-traded fund (ETF) generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchanged traded) that has the same investment objectives, strategies and policies.

• Sector Risk. Sector risks is the possibility that a certain sector may underperform other sectors or the market as a whole.

• Leverage Risk. Leverage risk is created when an investment, which includes, for example, an investment in a derivative contract, 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.

• Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the United States. Such markets have settlement and clearance procedures that differ from those in the United States. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. Inability to dispose of a portfolio security caused by settlement problems could result in losses to the Fund due to a subsequent decline in value of the portfolio security. In addition, security settlement and clearance procedures in some emerging countries may not fully protect the Fund against loss of its assets.

• Technology Risk. 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.

Performance: Bar Chart and Table

Risk/Return Bar Chart

The Fund is the successor to Federated Capital Income Fund, Inc. (the "Predecessor Fund") pursuant to a reorganization that became effective on May 27, 2003. Prior to that date, the Fund had no investment operations. Accordingly, the performance information and financial information provided in this Prospectus for the periods prior to the reorganization is historical information of the Predecessor Fund. The Predecessor Fund was managed by Passport Research Ltd., using the same personnel as the Fund's Adviser and had the same investment objectives, strategies and policies as the Fund. The performance information shown below will help you analyze the Fund's investment risks in light of its historical returns.

The bar chart and performance table below reflect historical performance data for the Fund and are intended to help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's A class total returns on a calendar year-by-year basis. The Average Annual Total Return Table shows returns for each class averaged over the stated periods, and includes comparative performance information. The Fund's performance will fluctuate, and past performance (before and after taxes) is not necessarily an indication of future results. Updated performance information for the Fund is available under the "Products" section at FederatedInvestors.com or by calling 1-800-341-7400.

Federated Capital Income Fund - A Class

The total returns shown in the bar chart do not reflect the payment of any sales charges or recurring shareholder account fees. If these charges or fees had been included, the returns shown would have been lower.

Within the periods shown in the bar chart, the Fund's A class highest quarterly return was 12.45% (quarter ended June 30, 2003). Its lowest quarterly return was (13.51)% (quarter ended December 31, 2008).

Average Annual Total Return Table

The Fund's IS class commenced operations on March 30, 2012. For the period prior to the commencement of operations of the IS class, the performance information shown below is for the A class. The performance of the A class has not been adjusted to reflect the expenses applicable to the IS class since the IS class has a lower expense ratio than the expense ratio of the A class. The performance of the A class has been adjusted to reflect the absence of sales charges applicable to A class and to remove any voluntary waiver of Fund expenses related to the A class that may have occurred during the period prior to the commencement of operations of the IS class.

In addition to Return Before Taxes, Return After Taxes is shown for the Fund's A class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for A class and after-tax returns for B, C, F and IS classes will differ from those shown for A class. Actual after-tax returns depend on each investor's personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through a 401(k) plan, an Individual Retirement Account or other tax-advantaged investment plan.

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 invests primarily across the domestic and international fixed-income markets represented by the following sectors: domestic investment-grade (including U.S. Treasury, government securities, mortgage backed and corporate debt investments); domestic noninvestment-grade corporate bonds (also known as "high yield" or "junk" bonds or, in the case of loans, "leveraged loans"); and international, without regard to credit quality, including trade finance loans and corporate and government securities issued and/or traded in emerging and/or developed markets. The Adviser will determine whether a security is investment grade based upon the credit ratings given by one or more nationally recognized statistical rating organizations (NRSROs). If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment that the security is comparable to investment grade. Within each sector, the Fund may also invest in inflation-indexed bonds. The Fund does not limit the amount that it may invest in any one of these sectors. The Fund does not have a specified minimum credit quality rating and may invest up to 100% of its total assets in investments rated below investment grade, including high yield bonds and emerging market debt. The Adviser will have the flexibility to manage the average duration to within a range of negative five (-5) to ten (+10) years. The Fund does not have any further specified duration target within that range and the duration of the Fund's portfolio is not otherwise limited as a matter of investment policy. From time to time, the Fund may receive equity securities in connection with the restructuring of defaulted corporate bonds, in general, and high yield bonds, in particular. The Fund may pursue investment opportunities that benefit from increases, as well as decreases, in the value of an investment. Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae"), and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association ("Ginnie Mae"). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities. The Fund may also invest in derivative contracts or hybrid instruments (such as, for example, futures contracts, option contracts and swap contracts), to implement its investment strategies as more fully described herein. The Fund may also invest its assets in securities of other investment companies, including the securities of affiliated money market funds, as an efficient means of implementing its investment strategies and/or managing its uninvested cash. The Fund may also invest in loan instruments, including trade finance loan instruments, and mortgage-backed, high yield, inflation-protected and emerging markets debt securities primarily by investing in another investment company (which is not available for general investment by the public) that owns those securities and that is advised by an affiliate of the Adviser. The Fund's investment in the trade finance loan instruments through these other investment companies may expose the Fund to risks of loss after redemption. The Fund may also invest in such securities directly. These other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. Because the Fund refers to fixed-income investments in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in fixed-income investments.
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: Interest Rate Risk. Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. In the event that the Fund has a negative average portfolio duration, the value of the Fund may decline in a declining interest rate environment. Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. Noninvestment-grade securities generally have a higher default risk than investment-grade securities. Such non-payment or default may reduce the value of the Fund's portfolio holdings, its share price and its performance. Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy. Agent Insolvency Risk. In a syndicated loan, the agent bank is the bank in the syndicate that undertakes the bulk of the administrative duties involved in the day-to-day administration of the loan. In the event of the insolvency of an agent bank, a loan could be subject to settlement risk as well as the risk of interruptions in the administrative duties performed in the day to day administration of the loan (such as processing LIBOR calculations, processing draws, pursuing certain available contractual remedies, etc.). Call Risk. Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a "call") at a price below its current market price. An increase in the likelihood of a call may reduce the security's price. Prepayment Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. Loan Prepayment Risk. During periods of declining interest rates or for other purposes, borrowers may exercise their option to prepay principal earlier than scheduled which may force the Fund to reinvest in lower-yielding instruments. Loan Liquidity Risk. Loans generally are subject to legal or contractual restrictions on resale. The liquidity of loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual loans. For example, if the credit quality of a loan unexpectedly declines significantly, secondary market trading in that loan can also decline for a period of time. During periods of infrequent trading, valuing a loan can be more difficult and buying and selling a loan at an acceptable price can be more difficult and delayed. Difficulty in selling a loan can result in a loss. Liquidity Risk. The fixed-income securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. Liquidity risk also 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 could incur losses. Risk of Investing in Loans. In addition to the risks generally associated with debt instruments, such as credit, market, interest rate, liquidity and derivatives risks, bank loans are also subject to the risk that the value of the collateral securing a loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. The Fund's access to the collateral may be limited by bankruptcy, other insolvency laws or by the type of loan the Fund has purchased. For example, if the Fund purchases a participation instead of an assignment, it would not have direct access to collateral of the borrower. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Loans generally are subject to legal or contractual restrictions on resale. Risk Associated with Noninvestment-Grade Securities. The Fund may invest a portion of its assets in securities rated below investment grade, also known as "junk bonds" or "leveraged loans," which may be subject to greater interest rate, credit and liquidity risks than investment-grade securities. Risk Related to the Economy. Lower-grade bond returns are sensitive to changes in the economy. The value of the Fund's portfolio may decline in tandem with a drop in the overall value of the stock market based on negative developments in the U.S. and global economies. Risk of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case. Currency Risk. Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience increased volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holding of such currencies or holding of non-U.S. dollar denominated securities. Eurozone Related Risk. A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries. Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market economies may also experience more severe downturns (with corresponding currency devaluations) than developed economies. 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. Risk of Inflation-Indexed Bonds. The value of inflation-indexed bonds is subject to the effects of changes in market interest rates caused by factors other than inflation ("real interest rates"). If interest rates rise due to reasons other than inflation, the Fund's investment in these securities may not be protected to the extent that the increase is not reflected in the security's inflation measure. 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 or the Fund's Statement of Additional Information (SAI), such as interest rate, credit, currency, liquidity and leverage risks. Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund. Risk of Loss after Redemption. The Fund may also invest in trade finance loan instruments primarily by investing in other investment companies (which are not available for general investment by the public) that owns those instruments and that are advised by an affiliate of the Adviser and is structured as an extended payment fund (EPF). In the EPF, the Fund, as shareholder, will bear the risk of investment loss during the period between when shares of such EPF are presented to the transfer agent of the EPF for redemption and when the net asset value of the EPF is determined for payment of the redeemed EPF shares (the "Redemption Pricing Date"). Technology Risk. 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.

Example

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. 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:

Expense Example Federated Unconstrained Bond Fund (USD $)	1 Year	3 Years	5 Years	10 Years
A	589	882	1,196	2,086
IS	116	362	628	1,386

Portfolio Turnover

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 113% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily across the domestic and international fixed-income markets represented by the following sectors: domestic investment-grade (including U.S. Treasury, government securities, mortgage backed and corporate debt investments); domestic noninvestment-grade corporate bonds (also known as "high yield" or "junk" bonds or, in the case of loans, "leveraged loans"); and international, without regard to credit quality, including trade finance loans and corporate and government securities issued and/or traded in emerging and/or developed markets. The Adviser will determine whether a security is investment grade based upon the credit ratings given by one or more nationally recognized statistical rating organizations (NRSROs). If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment that the security is comparable to investment grade. Within each sector, the Fund may also invest in inflation-indexed bonds. The Fund does not limit the amount that it may invest in any one of these sectors. The Fund does not have a specified minimum credit quality rating and may invest up to 100% of its total assets in investments rated below investment grade, including high yield bonds and emerging market debt. The Adviser will have the flexibility to manage the average duration to within a range of negative five (-5) to ten (+10) years. The Fund does not have any further specified duration target within that range and the duration of the Fund's portfolio is not otherwise limited as a matter of investment policy. From time to time, the Fund may receive equity securities in connection with the restructuring of defaulted corporate bonds, in general, and high yield bonds, in particular. The Fund may pursue investment opportunities that benefit from increases, as well as decreases, in the value of an investment.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae"), and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association ("Ginnie Mae"). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

The Fund may also invest in derivative contracts or hybrid instruments (such as, for example, futures contracts, option contracts and swap contracts), to implement its investment strategies as more fully described herein.

The Fund may also invest its assets in securities of other investment companies, including the securities of affiliated money market funds, as an efficient means of implementing its investment strategies and/or managing its uninvested cash. The Fund may also invest in loan instruments, including trade finance loan instruments, and mortgage-backed, high yield, inflation-protected and emerging markets debt securities primarily by investing in another investment company (which is not available for general investment by the public) that owns those securities and that is advised by an affiliate of the Adviser. The Fund's investment in the trade finance loan instruments through these other investment companies may expose the Fund to risks of loss after redemption. The Fund may also invest in such securities directly. These other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

Because the Fund refers to fixed-income investments in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in fixed-income investments.

What are the Main Risks of Investing in the Fund?

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:

• Interest Rate Risk. Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. In the event that the Fund has a negative average portfolio duration, the value of the Fund may decline in a declining interest rate environment.

• Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. Noninvestment-grade securities generally have a higher default risk than investment-grade securities. Such non-payment or default may reduce the value of the Fund's portfolio holdings, its share price and its performance.

• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

• Agent Insolvency Risk. In a syndicated loan, the agent bank is the bank in the syndicate that undertakes the bulk of the administrative duties involved in the day-to-day administration of the loan. In the event of the insolvency of an agent bank, a loan could be subject to settlement risk as well as the risk of interruptions in the administrative duties performed in the day to day administration of the loan (such as processing LIBOR calculations, processing draws, pursuing certain available contractual remedies, etc.).

• Call Risk. Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a "call") at a price below its current market price. An increase in the likelihood of a call may reduce the security's price.

• Prepayment Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities.

• Loan Prepayment Risk. During periods of declining interest rates or for other purposes, borrowers may exercise their option to prepay principal earlier than scheduled which may force the Fund to reinvest in lower-yielding instruments.

• Loan Liquidity Risk. Loans generally are subject to legal or contractual restrictions on resale. The liquidity of loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual loans. For example, if the credit quality of a loan unexpectedly declines significantly, secondary market trading in that loan can also decline for a period of time. During periods of infrequent trading, valuing a loan can be more difficult and buying and selling a loan at an acceptable price can be more difficult and delayed. Difficulty in selling a loan can result in a loss.

• Liquidity Risk. The fixed-income securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. Liquidity risk also 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 could incur losses.

• Risk of Investing in Loans. In addition to the risks generally associated with debt instruments, such as credit, market, interest rate, liquidity and derivatives risks, bank loans are also subject to the risk that the value of the collateral securing a loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. The Fund's access to the collateral may be limited by bankruptcy, other insolvency laws or by the type of loan the Fund has purchased. For example, if the Fund purchases a participation instead of an assignment, it would not have direct access to collateral of the borrower. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Loans generally are subject to legal or contractual restrictions on resale.

• Risk Associated with Noninvestment-Grade Securities. The Fund may invest a portion of its assets in securities rated below investment grade, also known as "junk bonds" or "leveraged loans," which may be subject to greater interest rate, credit and liquidity risks than investment-grade securities.

• Risk Related to the Economy. Lower-grade bond returns are sensitive to changes in the economy. The value of the Fund's portfolio may decline in tandem with a drop in the overall value of the stock market based on negative developments in the U.S. and global economies.

• Risk of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.

• Currency Risk. Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience increased volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holding of such currencies or holding of non-U.S. dollar denominated securities.

• Eurozone Related Risk. A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.

• Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market economies may also experience more severe downturns (with corresponding currency devaluations) than developed economies.

• 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.

• Risk of Inflation-Indexed Bonds. The value of inflation-indexed bonds is subject to the effects of changes in market interest rates caused by factors other than inflation ("real interest rates"). If interest rates rise due to reasons other than inflation, the Fund's investment in these securities may not be protected to the extent that the increase is not reflected in the security's inflation measure.

• 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 or the Fund's Statement of Additional Information (SAI), such as interest rate, credit, currency, liquidity and leverage risks.

• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.

• Risk of Loss after Redemption. The Fund may also invest in trade finance loan instruments primarily by investing in other investment companies (which are not available for general investment by the public) that owns those instruments and that are advised by an affiliate of the Adviser and is structured as an extended payment fund (EPF). In the EPF, the Fund, as shareholder, will bear the risk of investment loss during the period between when shares of such EPF are presented to the transfer agent of the EPF for redemption and when the net asset value of the EPF is determined for payment of the redeemed EPF shares (the "Redemption Pricing Date").

• Technology Risk. 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.

Performance: Bar Chart and Table

Risk/Return Bar Chart

The bar chart and performance table below reflect historical performance data for the Fund and are intended to help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's IS class total returns on a calendar year-by-year basis.

Average Annual Total Return Table

In addition to Return Before Taxes, Return After Taxes is shown for the IS class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for IS class and after-tax returns for the A class may differ for those shown for the IS class. Actual after-tax returns depend on each investor's personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding shares through a 401(k) plan, an Individual Retirement Plan or other tax-advantaged investment plan.
