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.

1

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:

Share Class	1 Year	3 Years	5 Years	10 Years
A:
Expenses assuming redemption	$710	$1,048	$1,407	$2,418
Expenses assuming no redemption	$710	$1,048	$1,407	$2,418
B:
Expenses assuming redemption	$790	$1,139	$1,465	$2,532
Expenses assuming no redemption	$240	$ 739	$1,265	$2,532
C:
Expenses assuming redemption	$340	$ 739	$1,265	$2.706
Expenses assuming no redemption	$240	$ 739	$1,265	$2,706
IS :
Expenses assuming redemption	$139	$ 434	$ 750	$1,646
Expenses assuming no redemption	$139	$ 434	$ 750	$1,646

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 16% of the average value of its portfolio.

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. 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 Foreign Investing. The foreign markets in which the Fund invests may be subject to economic or political conditions which are less favorable than those of the United States and may lack financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies.
■	Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in American Depositary Receipts 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.
■	Currency Risk. Because the exchange rates for currencies fluctuate daily, prices of the foreign securities in which the Fund invests are more volatile than prices of securities traded exclusively in the United States.
■	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 derivative contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.
■	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.
■	Risk Related to Investing for Value. Due to their relatively low valuations, value stocks are typically less volatile than growth stocks. However, value stocks may lag behind growth stocks in an up market.
■	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.
■	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

3

	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.
■	Exchange-Traded Funds Risk. 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). In addition, ETFs may be subject to the following risks that do not apply to conventional funds: (i) the market price of an ETF's shares may trade above or below their net asset value; (ii) an active trading market for an ETF's shares may not develop or be maintained; or (iii) trading of an ETF's shares may be halted if the listing exchange's officials deem such action appropriate.
■	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, such as stock market, interest rate, credit, currency, liquidity and leverage risks.
■	Liquidity Risk. Trading opportunities are more limited for equity securities that are not widely held. This may make it more difficult to sell or buy a security at a favorable price or time. 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.
■	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. Investments can have these same results if their returns are based on a multiple of a specified index, security or other benchmark.
■	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.
■	Technology Risk. Proprietary and third-party data 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 A class total returns on a calendar year-by-year basis. The Fund changed its investment strategy on September 4, 2003. Until that time, the Fund invested primarily in securities of companies in the financial services industry. 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 33.12% (quarter ended June 30, 2009). Its lowest quarterly return was (25.69)% (quarter ended September 30, 2011).

Average Annual Total Return Table

The Fund's IS class commenced operations on June 21, 2010. For the period prior to the commencement of operations of the IS class, the performance information shown 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 IS class has a lower expense ratio than the expense ratio of A class. The performance of A class has been adjusted to reflect the absence of sales charges and 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

5

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.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
