&lt;div style="margin-top:0px;font-family:'times new roman';color:rgb(0, 0, 0);font-size:9pt;text-align:justify;margin-bottom:4pt;"&gt;The Fund outperformed the Standard &amp;amp; Poor&#x2019;s 500 Index (&#x201c;S&amp;amp;P 500&#x201d; or the &#x201c;Index&#x201d;) for the period. The Fund&#x2019;s Class A shares delivered a total return on net asset value of 25.43%, versus a 19.56% return for the S&amp;amp;P 500. The Fund invests principally in common stocks (including American Depositary Receipts) issued by medium- and large-capitalization companies. The Fund considers companies with market capitalizations between $3 billion and $10 billion to be medium-capitalization companies and companies with market capitalizations of at least $10 billion to be large-capitalization companies. The Fund has the flexibility to invest in foreign securities.&lt;/div&gt; &lt;/div&gt;
