  <rr:RiskNarrativeTextBlock contextRef="Duration_29Mar2016_29Mar2016S000002837_MemberRetail_Member">An investment in the Fund could lose money over short or even long periods. You should expect the Fund&amp;#8217;s share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund&amp;#8217;s performance:&lt;br /&gt;&lt;br /&gt;&amp;#149; Stock market risk, which is the chance that stock prices overall will decline, causing the prices of convertible securities to decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund&amp;#8217;s investments in securities that are convertible into foreign stocks may perform differently from their U.S. counterparts.&lt;br /&gt;&lt;br /&gt;&amp;#149; Credit risk, which is the chance that the issuer of a convertible security will fail to pay interest, dividends, or principal in a timely manner or that negative perceptions of the issuer&amp;#8217;s ability to make such payments will cause the price of that security to decline. Companies that issue convertible securities are often small to mid-size, and they often have credit ratings below investment grade. In addition, the credit rating of a company&amp;#8217;s convertible securities is generally lower than that of its nonconvertible debt securities. Convertible securities are normally considered &amp;#8221;junior&amp;#8220; securities&amp;#8212;that is, the issuer usually must make required interest and principal payments on its nonconvertible debt before it can make payments on its convertible securities. If an issuer stops making interest or principal payments, these securities may become worthless and the Fund could lose its entire investment. Reflecting the universe of convertible securities, most of the Fund&amp;#8217;s rated holdings are below investment grade (commonly referred to as &amp;#8220;junk bonds&amp;#8221;), and some may be unrated. Therefore, credit risk is greater for the Fund than for funds that invest in higher-grade securities.&lt;br /&gt;&lt;br /&gt;&amp;#149; Interest rate risk, which is the chance that prices of convertible securities will decline along with overall bond prices because of rising interest rates. Convertible securities are more sensitive to interest rate changes when their predetermined conversion price is much higher than the price of the issuing company&amp;#8217;s common stock, and are less sensitive to interest rate changes as the price of the issuing company&amp;#8217;s stock approaches the predetermined conversion price.&lt;br /&gt;&lt;br /&gt;&amp;#149; Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. In addition, significant investment in the information technology sector subjects the Fund to proportionately higher exposure to the risks of this sector.&lt;br /&gt;&lt;br /&gt;&amp;#149; Liquidity risk, which is the chance that the Fund may not be able to sell a security in a timely manner at a desired price.&lt;br /&gt;&lt;br /&gt;&amp;#149; Country/regional risk, which is the chance that world events&amp;#8212;such as political upheaval, financial troubles, or natural disasters&amp;#8212;will adversely affect the value and/or liquidity of securities issued by companies in foreign countries or regions. Because the Fund may invest a large portion of its assets in securities of companies located in any one country or region, the Fund&amp;#8217;s performance may be hurt disproportionately by the poor performance of its investments in that area.&lt;br /&gt;&lt;br /&gt;&amp;#149; Currency hedging risk, which is the chance that the currency hedging transactions entered into by the Fund may not perfectly offset the Fund&amp;#8217;s foreign currency exposure. For example, the Fund will decline in value if it underhedges a currency that has weakened or overhedges a currency that has strengthened relative to the U.S. dollar.&lt;br /&gt;&lt;br /&gt;An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</rr:RiskNarrativeTextBlock>
