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 the 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:

Share Class	1 Year	3 Years	5 Years	10 Years
A:
Expenses assuming redemption	$588	$ 879	$1,191	$2,075
Expenses assuming no redemption	$588	$ 879	$1,191	$2,075
B:
Expenses assuming redemption	$770	$1,079	$1,364	$2,313
Expenses assuming no redemption	$220	$ 679	$1,164	$2,313
C:
Expenses assuming redemption	$320	$ 679	$1,164	$2,503
Expenses assuming no redemption	$220	$ 679	$1,164	$2,503
IS:
Expenses assuming redemption	$119	$ 372	$ 644	$1,420
Expenses assuming no redemption	$119	$ 372	$ 644	$1,420

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 20% 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 in emerging markets fixed-income investments. The Fund's investments may be denominated in foreign currencies or U.S. dollars, and may be of any duration. The Fund does not limit the amount it may invest in investments rated below investment grade. The Fund may invest in derivative contracts to implement its investment strategies, as more fully described herein. When the Fund's investment adviser (“Adviser”) considers the risk/return prospects of emerging markets equity securities to be attractive, the Fund may also opportunistically invest in convertible securities, equity securities or pooled vehicles such as exchange-traded funds (ETFs) or other investment companies in order to gain exposure to a specific region, country, or market sector or for other reasons consistent with its investment strategy.

Because the Fund refers to emerging market debt 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 emerging market 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:

■	Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. 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.
■	Risk Associated with Noninvestment-Grade Securities. The Fund may invest a portion of its assets in securities rated below investment grade that generally are 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 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 economies.
■	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. OTC derivative contracts generally carry greater liquidity risk than exchange-traded contracts. This risk may be increased in times of financial stress, if the trading market for OTC derivative contracts becomes restricted.
■	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.
■	Interest Rate Risk. Prices of fixed-income securities rise and fall in response to interest rate changes for similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. Also, interest rate changes have a greater effect on the price of fixed-income securities with longer durations. Duration measures the price sensitivity of a fixed-income security to changes in interest rates.

■	Risk of Loss after Redemption. The investment companies in which the Fund invests may cause the Fund to experience delays from the time it requests a redemption to the time that such redemption is processed.
■	Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement. Credit enhancement is designed to help assure timely pay of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions.
■	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 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.
■	Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. In addition, security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets.
■	Risk of Non-Diversified Fund. The Fund is non-diversified. Compared to diversified mutual funds, it may invest a higher percentage of its assets among fewer issuers of portfolio securities. In certain situations, being non-diversified may reduce the Fund's credit risk by enabling it to avoid investing in certain countries, regions or sectors that exhibit above average credit risk.
■	Stock Market Risk. The value of equity securities in a Fund's portfolio will fluctuate and, as a result, a 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.
■	Risk of Exchange-Traded Funds. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange traded) that has the same investment objectives,

	strategies and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.
■	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 Fund is non-diversified. Compared to diversified mutual funds, it may invest a higher percentage of its assets among fewer issuers of portfolio securities. This increases the Fund's risk by magnifying the impact (positively or negatively) that any one issuer has on the Fund's Share price and 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 and Table

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.

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 18.68% (quarter ended June 30, 2009). Its lowest quarterly return was (13.70)% (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 commencement of operations of IS class, the performance information shown is for the Fund's A class. The performance of A class has not been adjusted to reflect the expenses of IS class since IS class has a lower expense ratio than the expense ratio of A class. The performance of A class has been adjusted to remove any voluntary waiver of Fund expenses related to A class that may have occurred during the period prior to commencement of operations of 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 and IS classes will differ from those shown below 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 tax-deferred programs, such as a 401(k) plan, an Individual Retirement Account (IRA) or other tax-advantaged investment plan.
