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 in the fund for the time periods indicated. It shows your costs if you sold your shares at the end of the period or continued to hold them. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Share Status	1 Year	3 Years	5 Years	10 Years
Class A	Sold or Held	$734	$1,068	$1,425	$2,427
Class C	Sold	$344	$751	$1,285	$2,746
	Held	$244	$751	$1,285	$2,746
Class I	Sold or Held	$144	$446	$771	$1,691

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 54% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund provides international exposure to the real estate securities market, focusing exclusively on companies with a rental business profile. Rental companies derive 70% or more of total revenue from rental income and are most similar in business profile to U.S. real estate investment trust (REITs).

Under normal circumstances, the fund invests at least 80% of its assets in equity securities issued by non-U.S companies of any capitalization that are principally engaged in the real estate industry, including common stock, preferred stock and other equity securities issued by real estate companies, such as REITs and similar REIT-like entities. The fund may, at times, invest up to 20% of its assets in U.S. REIT securities. Additionally, the fund normally invests in real estate related securities of issuers in developed countries, however it may invest up to 20% of its assets in issuers incorporated in emerging market countries. The fund concentrates its assets in the real estate industry and is non-diversified under federal securities laws.

Principal Risks

The fund may not achieve its objectives, and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are those associated with:

> Emerging Market Investing Risk. The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.

> Equity REIT Securities Risk. The risk that the value of the fund’s shares will be negatively affected by changes in real estate values or economic conditions, credit risk and interest rate fluctuations, and changes in the value of the underlying real estate and defaults by borrowers.

> Equity Securities Risk. The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund’s shares over short or extended periods.

> Foreign Investing Risk. The risk that the prices of foreign securities may be more volatile than those of their domestic counterparts.

> Geographic Concentration Risk. The risk that events negatively affecting the fiscal stability of a particular geographic location in which the fund focuses its investments will cause the value of the fund’s shares to decrease, perhaps significantly. To the extent the fund concentrates its assets in a particular country or region, the fund is more vulnerable to financial, economic or other political developments in that country or region as compared to a fund that does not concentrate holdings in a particular country or region.

> Industry/Sector Concentration Risk. The risk that events negatively affecting real estate securities will cause the value of the fund’s shares to decrease, perhaps significantly. Since the fund concentrates its assets in real estate related securities, the fund is more vulnerable to conditions that negatively affect real estate related securities as compared to a fund that does not concentrate holdings in such securities.

> Market Volatility Risk. The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.

> Non-Diversification Risk. The risk that the fund will be more susceptible to factors negatively impacting the securities in its portfolio to the extent that each such security represents a significant portion of the fund’s assets.

For a more detailed description of the above risks, see “More Information About Risks Related to Principal Investment Strategies” in the fund’s prospectus.

The S&P 500^® Index is a free-float adjusted market capitalization-weighted index of 500 of the largest U.S. companies. The FTSE EPRA/NAREIT Developed Rental ex-U.S. Index is a free-float market capitalization index measuring international real estate securities, which meet minimum size, liquidity and investment focus criteria. The index is a sub-set of the FTSE EPRA NAREIT Investment Focus Index Series, which separates the existing constituents into both Rental and Non-Rental Indices. A company is classified as Rental if the rental revenue from properties is greater than or equal to 70% of total revenue. The classification is based on revenue sources as disclosed in the latest published financial statement. The indexes are calculated on a total return basis with dividends reinvested.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.

Taxes

Such tax-deferred arrangements may be taxed later upon withdrawal of monies from those arrangements.

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 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 financial advisor to recommend the fund over another investment. Ask your financial advisor or visit your financial intermediary’s website for more information.
