each year, and that the fund&#x2019;s operating expenses remain the same. The example also assumes that any 
current expense limitation arrangement remains in place for the period noted in the previous table; therefore, 
the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for

a substantial portion of revenues or profits from servicing real estate firms, or that are unrelated 
to the real estate business.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;Stock selection is based on fundamental, bottom-up analysis that generally seeks 
to identify high-quality companies with both good appreciation prospects and income-producing potential. 
Factors considered by the portfolio manager in selecting real estate companies include one or more of 
the following: relative valuation; free cash flow; undervalued assets; quality and &lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;experience

things, &lt;/span&gt;&lt;span style="font-size:8.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;general and local economic conditions, interest rate movements, changes in zoning

securities and may lose value because of adverse local, political, social, or economic developments overseas,

of non-U.S. issuers are subject to trading markets with potential governmental interference, varying 
regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from 
those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to 
hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared 
with U.S. markets. The fund&#x2019;s overall foreign investing risk is increased to the extent it has exposure

recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural 
disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the

There is a chance that stock prices overall will decline because stock markets tend to move in cycles, 
with periods of rising and falling prices. The value of stocks held by the fund may decline due to general 
weakness or volatility in the stock markets in which the fund invests or because of factors that affect 
a particular company or industry.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

the average annual total returns for each class of the fund that has been in operation for at least one 
full calendar year. The fund&#x2019;s performance information included in the table is compared with a regulatory 
required index that represents an overall securities market (Regulatory Benchmark). In addition, the 
table may also include one or more indexes that more closely aligns to the fund&#x2019;s investment strategy 
(Strategy Benchmark(s)).&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;In addition, the table shows hypothetical after-tax returns to demonstrate how 
taxes paid by a shareholder may influence returns. 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. Actual after-tax returns depend on an investor&#x2019;s tax situation and may differ from those shown. 
After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred 
arrangements, such as a 401(k) account or an IRA. After-tax returns are shown only for the Investor Class 
and will differ for other share classes.&lt;/p&gt;</rr:PerformanceTableNarrativeTextBlock>
