Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund&#x2019;s portfolio. &lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt; &lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt;An investment in the Fund may not be appropriate for all investors. The Fund&#x2019;s principal risks include:&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Market risk &lt;/b&gt;&#x2014; The risk that all or a majority of the securities in a certain market &#x2014;&#160;such as the stock or bond market &#x2014;&#160;will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Industry and sector risk &lt;/b&gt;&#x2014; The risk that the value of securities in a particular industry or sector &#160;(such as financial services or manufacturing) will decline because of changing expectations for the performance of that industry or sector.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Company size risk &lt;/b&gt;&#x2014; The risk that investments in small- and/or medium-sized companies may be&lt;b&gt; &lt;/b&gt;more volatile than those of larger companies because of limited financial resources or dependence on narrow product lines.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Interest rate risk&lt;/b&gt; &#x2014;&#160;The risk that securities will decrease in value if interest rates rise. The risk is generally associated with bonds; however, because small- and medium-sized companies and companies in the real estate sector often borrow money to finance their operations, they may be adversely affected by rising interest rates. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Liquidity risk &lt;/b&gt;&#x2014; The possibility that investments cannot be readily sold within seven calendar days at approximately the price at which a fund has valued them.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Government and regulatory risk &lt;/b&gt;&#x2014; The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance. &lt;/span&gt;&lt;/p&gt;

While some instruments may contemplate a scenario where LIBOR or a similar rate is no longer available by providing for an alternative rate setting methodology, not all instruments have such fallback provisions and the effectiveness of replacement rates is uncertain. The abandonment of LIBOR and similar rates could affect the value and liquidity of instruments that reference such rates, especially those that do not have fallback provisions. The use of alternative reference rate products may impact investment strategy performance.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Active management and selection risk&lt;/b&gt; &#x2014;&#160;The risk that the securities selected by a fund&#x2019;s management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies.

These costs, which are not reflected in the annual fund operating expenses or in the example, affect the Fund&#x2019;s performance.

The Manager focuses on free cash flow in its individual stock selection, seeking companies that it believes have a sustainable ability to buy back shares, lower debt, and/or increase or initiate dividends. Under normal circumstances, at least 80% of the Fund&#x2019;s net assets, plus the amount of any borrowings for investment purposes, will be in investments of small-capitalization companies (80% policy). The Fund considers small-capitalization companies to be companies with a market capitalization generally less than 3.5 times the dollar-weighted, median market capitalization of the Russell 2000&lt;/span&gt;&lt;span style="font-family:Times New Roman;vertical-align:super"&gt;&#xae;&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt; Index at the time of purchase.

Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund&#x2019;s portfolio. &lt;span style="font-family:Times New Roman"&gt; An investment in the Fund may not be appropriate for all investors. The Fund&#x2019;s principal risks include:&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Market risk &lt;/b&gt;&#x2014; The risk that all or a majority of the securities in a certain market &#x2014;&#160;such as the stock or bond market &#x2014;&#160;will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Industry and sector risk &lt;/b&gt;&#x2014; The risk that the value of securities in a particular industry or sector &#160;(such as financial services or manufacturing) will decline because of changing expectations for the performance of that industry or sector.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Company size risk &lt;/b&gt;&#x2014; The risk that investments in small- and/or medium-sized companies may be&lt;b&gt; &lt;/b&gt;more volatile than those of larger companies because of limited financial resources or dependence on narrow product lines.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Interest rate risk&lt;/b&gt; &#x2014;&#160;The risk that securities will decrease in value if interest rates rise. The risk is generally associated with bonds; however, because small- and medium-sized companies and companies in the real estate sector often borrow money to finance their operations, they may be adversely affected by rising interest rates. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Foreign risk &lt;/b&gt;&#x2014; The risk that foreign securities (particularly in emerging markets) may be adversely&lt;b&gt; &lt;/b&gt;affected by political instability, changes in currency exchange rates, inefficient markets and higher transaction costs, foreign economic conditions, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Real estate industry risk &lt;/b&gt;&#x2014; This risk includes, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; overbuilding; extended vacancies of properties; increases in competition, property taxes, and operating expenses; changes in zoning laws; costs resulting from the cleanup of, and liability to third parties resulting from, environmental problems; casualty for condemnation losses; uninsured damages from floods, earthquakes, or other natural disasters; limitations on and variations in rents; and changes in interest rates.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Liquidity risk &lt;/b&gt;&#x2014; The possibility that investments cannot be readily sold within seven calendar days at approximately the price at which a fund has valued them.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Government and regulatory risk &lt;/b&gt;&#x2014; The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance. &lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;&lt;b&gt;IBOR risk &lt;/b&gt;&#x2014; The risk that changes related to the use of the London Interbank Offered Rate (LIBOR) or similar interbank offered rates (&#x201c;IBORs,&#x201d; such as the Euro Overnight Index Average (EONIA)) could have adverse impacts on financial instruments that reference LIBOR or a similar rate. While some instruments may contemplate a scenario where LIBOR or a similar rate is no longer available by providing for an alternative rate setting methodology, not all instruments have such fallback provisions and the effectiveness of replacement rates is uncertain. The abandonment of LIBOR and similar rates could affect the value and liquidity of instruments that reference such rates, especially those that do not have fallback provisions. The use of alternative reference rate products may impact investment strategy performance.&lt;/span&gt;&lt;/p&gt;

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. In addition, the example shows expenses for Class C shares, assuming those shares were not redeemed at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: &lt;/span&gt;&lt;/p&gt;

The Fund will use derivatives for both hedging and &lt;/span&gt;&lt;span style="font-family:Times New Roman;background-color:#FFFFFF;-sec-ix-redline:true"&gt;non-hedging purposes; as a substitute for purchasing or selling securities; and to manage the Fund&#x2019;s portfolio characteristics.&lt;/span&gt;&lt;span style="font-family:Times New Roman;background-color:#FFFFFF"&gt; For example, the Fund may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; and credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return.&lt;/span&gt;&lt;/p&gt;

The Manager may also permit MIMGL and Macquarie Funds Management Hong Kong Limited (MFMHKL) to execute Fund equity security trades on behalf of the Manager. The Manager may also permit MIMEL and MIMGL to exercise investment discretion and perform trading for fixed income securities in certain markets where the Manager believes it will be beneficial to utilize MIMEL&#x2019;s or MIMGL&#x2019;s specialized market knowledge, and the Manager may also seek quantitative support from MIMGL. MIMGL is also responsible for managing real estate investment trust securities and other equity asset classes to which the portfolio managers may allocate assets from time to time.&lt;/span&gt;&lt;/p&gt;

Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund&#x2019;s portfolio. &lt;span style="font-family:Times New Roman"&gt; An investment in the Fund may not be appropriate for all investors. The Fund&#x2019;s principal risks include:&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Market risk &lt;/b&gt;&#x2014; The risk that all or a majority of the securities in a certain market &#x2014;&#160;such as the stock or bond market &#x2014;&#160;will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin:0"&gt;&#160;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Credit risk &lt;/b&gt;&#x2014; The risk that an issuer of a debt security, including a governmental issuer or an entity that insures a bond, may be unable to make interest payments and/or repay principal in a timely manner.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;High yield (junk bond) risk&lt;/b&gt; &#x2014; The risk that high yield securities, commonly known as &#x201c;junk bonds,&#x201d; are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of income and principal than are higher-rated securities. High yield bonds are sometimes issued by municipalities that have less financial strength and therefore have less ability to make projected debt payments on the bonds.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Interest rate risk&lt;/b&gt; &#x2014;&#160;The risk that the prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes.&#160;A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Real estate industry risk &lt;/b&gt;&#x2014; This risk includes, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; overbuilding; extended vacancies of properties; increases in competition, property taxes, and operating expenses; changes in zoning laws; costs resulting from the cleanup of, and liability to third parties resulting from, environmental problems; casualty for condemnation losses; uninsured damages from floods, earthquakes, or other natural disasters; limitations on and variations in rents; and changes in interest rates.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt Times New Roman;margin-top:0pt;margin-bottom:6pt"&gt;&lt;b&gt;Derivatives risk &lt;/b&gt;&#x2014; Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in the opposite direction from what the portfolio manager anticipated. When used for hedging, the change in value of the derivatives instrument may also not correlate specifically with the currency, rate, or other risk being hedged, in which case a fund may not realize the intended benefits. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to, among other reasons, financial difficulties (such as a bankruptcy or reorganization).&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Leveraging risk&lt;/b&gt;&lt;b&gt; &lt;/b&gt;&#x2014; The risk that certain fund transactions, such as reverse repurchase agreements, short sales, loans of portfolio securities, and the use of&lt;b&gt; &lt;/b&gt;when-issued, delayed delivery or forward commitment transactions, or derivatives instruments, may give rise to leverage, causing a fund to be more volatile than if it had not been leveraged, which may result in increased losses to the fund.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;&lt;b&gt;Exchange-traded fund&lt;/b&gt;&lt;i&gt; &lt;/i&gt;&lt;b&gt;risk&lt;/b&gt; &#x2014;&#160;The risks of investing in an exchange-traded fund (ETF) typically reflect the risks of the types of instruments in which the ETF invests. Because ETFs are investment companies, a fund will bear its proportionate share of the fees and expenses of an investment in an ETF. As a result, a fund's expenses may be higher and performance may be lower. &lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Foreign risk &lt;/b&gt;&#x2014; The risk that foreign securities (particularly in emerging markets) may be adversely&lt;b&gt; &lt;/b&gt;affected by political instability, changes in currency exchange rates, inefficient markets and higher transaction costs, foreign economic conditions, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Government and regulatory risk &lt;/b&gt;&#x2014; The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance. &lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;&lt;b&gt;IBOR&lt;/b&gt;&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt; risk &lt;/b&gt;&#x2014; The risk that changes related to the use of the London Interbank Offered Rate (LIBOR) &lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;or similar interbank offered rates (&#x201c;IBORs,&#x201d; such as the Euro Overnight Index Average (EONIA)) &lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt;could have adverse impacts on financial instruments &lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;that&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt; reference LIBOR&lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt; or a similar rate.&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt; While some instruments may contemplate a scenario where LIBOR&lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt; or a similar rate&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt; is no longer available by providing for an alternative rate setting methodology, not all instruments have such fallback provisions and the effectiveness of replacement rates is uncertain. The abandonment of LIBOR &lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;and similar rates &lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt;could affect the value and liquidity of instruments &lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;that&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt; reference &lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;such rates&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt;, especially those that do not have fallback provisions&lt;/span&gt;&lt;span style="font-family:Times New Roman;-sec-ix-redline:true"&gt;. The use of alternative reference rate products may impact investment strategy performance&lt;/span&gt;&lt;span style="font-family:Times New Roman"&gt;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Liquidity risk &lt;/b&gt;&#x2014; The possibility that investments cannot be readily sold within seven calendar days at approximately the price at which a fund has valued them.&lt;/span&gt;&lt;/p&gt;
&lt;p style="font:10pt NewsGoth Lt BT;margin-top:0pt;margin-bottom:6pt"&gt;&lt;span style="font-family:Times New Roman"&gt;&lt;b&gt;Active management and selection risk&lt;/b&gt; &#x2014;&#160;The risk that the securities selected by a fund&#x2019;s management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.&lt;/span&gt;&lt;/p&gt;
