The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same and that the fee waivers currently in place are not renewed beyond July 31, 2028. Although your actual costs may be higher or lower, based on these assumptions your costs would be:</div> 700 700 208 208 95 95 107 107 1009 1009 690 690 345 345 383 383 1417 1417 1277 1277 698 698 762 762 2553 2553 2871 2871 1695 1695 1828 1828 Portfolio Turnover <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;text-decoration:none;margin-top:1em;margin-bottom:1em;">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 90% of the average value of its portfolio. </div> 0.90 Principal Investment Strategies <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">Under normal circumstances, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in common stocks, preferred securities and other equity securities issued by U.S. and non-U.S. companies in the real estate industry, including real estate investment trusts (“</span><span style="font-size:10.0pt;font-family:arial;font-style:italic;color:#000000;font-weight:normal;text-decoration:none">REITs</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">”) and similar REIT-like entities.

Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Derivatives Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—The use of derivatives is a highly specialized activity that can involve investment techniques, risks, and tax planning different from those associated with more traditional investment instruments and involves transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivative instruments can be used to acquire or to transfer the risk and returns of a security or other asset without buying or selling the security or asset, and the risks associated with investing in such derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. These instruments may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. An over-the-counter derivative transaction between the Fund and a counterparty that is not cleared through a central counterparty also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. The payment obligation for a cleared derivative transaction is guaranteed by a central counterparty, which exposes the Fund to the creditworthiness of the central counterparty.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Emerging Markets Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund’s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Equity Security Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. </span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Foreign Investment Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax </span></div><div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;text-decoration:none;margin-top:1em;margin-bottom:1em;">environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. </div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Market Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—The market value of the Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund’s investments whether or not the Fund invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund’s assets can decline.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Preferred Security Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Real Estate Investment Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—Because the Fund invests significantly in securities of issuers in the real estate industry, the Fund has greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities. The Fund's investments in the real estate market have many of the same risks as direct ownership of real estate. These risks include, among others: declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates. The real estate sector is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Real estate values have been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future. Any such fluctuations in real estate values also may affect the value of an investment in the Fund.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">REITs Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">— In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. REITs may be affected by changes in real estate values, rents, property taxes and interest rates. Further, REITs are dependent upon specialized management skills and cash flows, and may have their investments in relatively few properties, or in a small geographic area or a single property type. Failure of a company to qualify as a REIT under federal tax law, or changes to federal tax law or regulations governing REITs, may have adverse consequences to the Fund. In addition, REITs have their own expenses, and the Fund will bear a proportionate share of those expenses. Many REITs utilize leverage (and some may be highly leveraged), which increases investment risk and could potentially magnify the Fund’s losses.</span></div> <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;font-style:normal;margin-top:1em;margin-bottom:1em;"><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:bold;text-decoration:none">Small- and Mid-Cap Company Risk</span><span style="font-size:10.0pt;font-family:arial;font-style:normal;color:#000000;font-weight:normal;text-decoration:none">—Even larger REITs may be small- to medium-sized companies in relation to the equity markets as a whole. Securities of small-cap companies involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.</span></div> Fund Performance <div style="font-size:10.0pt;font-family:arial;text-align:left;color:#000000;font-weight:normal;text-decoration:none;margin-top:1em;margin-bottom:1em;">The following bar chart and table provide some indication of the potential risks of investing in the Fund.
