Convertible &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities are generally debt securities or preferred stock that may be converted into common stock. Convertible &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities typically pay current income as either interest (debt security convertibles) or dividends (preferred stock). A &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;convertible security&#x2019;s value usually reflects both the stream of current income payments and the market value of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;underlying common stock. Preferred stock is a class of stock that often pays dividends at a specified rate and has &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;preference over common stock in dividend payments and liquidation of assets. Preferred stock may also be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;convertible into common stock.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest up to 25% of its total assets in securities of foreign issuers.

Convertible &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities are generally debt securities or preferred stock that may be converted into common stock. Convertible &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities typically pay current income as either interest (debt security convertibles) or dividends (preferred stock). A &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;convertible security&#x2019;s value usually reflects both the stream of current income payments and the market value of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;underlying common stock. Preferred stock is a class of stock that often pays dividends at a specified rate and has &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;preference over common stock in dividend payments and liquidation of assets. Preferred stock may also be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;convertible into common stock.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest up to 25% of its total assets in securities of foreign issuers.
