In seeking to achieve the Fund&amp;#146;s long-term capital growth objective, the Fund invests in common stocks of growth companies.

Several factors are considered in the Adviser&amp;#146;s evaluation of a company, including: &lt;/font&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;unique product or service, &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;growing product demand, &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;dominant and growing market share, &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;management experience and capabilities, and &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;strong financial condition. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;When selling equity securities for the Fund, the Adviser considers several factors, including changes in a company&amp;#146;s fundamentals and anticipated earnings. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;The fixed-income portion of the Fund&amp;#146;s portfolio is invested primarily in a diversified portfolio of debt securities that may include the following securities: &lt;/font&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;mortgage-backed securities (including collateralized mortgage obligations), such as securities issued by Government National Mortgage Association (GNMA securities are backed by the full faith and credit of the U.S. government), Federal Home Loan Mortgage Corporation (FHLMC) and Federal National Mortgage Association (FNMA) (FHLMC and FNMA securities are backed by the credit of the issuing governmental agency), &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;asset-backed securities collateralized by assets such as automobile and credit card receivables, utilities, home improvement loans and home equity loans, &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;obligations of the U.S. government, its agencies and instrumentalities, &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;corporate debt securities, &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;taxable municipal securities, and &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;short-term debt obligations, including commercial paper and bank instruments, such as certificates of deposit, time deposits, and bankers&amp;#146; acceptances. The Fund invests primarily in debt securities that, at the time of purchase, are either rated investment-grade (BBB or above by Standard &amp;amp; Poor&amp;#146;s or Baa or above by Moody&amp;#146;s Investor Services), or, if unrated, determined to be of comparable quality by the Adviser. Unrated securities will not exceed 20% of the fixed-income portion of the Fund&amp;#146;s portfolio. As of September 30, 2012, 1.9% of the fixed-income portion of the Fund&amp;#146;s portfolio was in unrated securities. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;In selecting fixed-income securities for the Fund, the Adviser seeks fixed-income securities providing maximum total return. In making purchase and sales decisions for the Fund, the Adviser considers its economic outlook and interest rate forecast, as well as its evaluation of a fixed-income security&amp;#146;s credit quality, yield, maturity, and liquidity. Based upon its economic outlook, the Adviser attempts to shift the fixed-income sector concentrations of the portfolio. Based upon its interest rate forecast, the Adviser attempts to shift the fixed-income portfolio&amp;#146;s average effective duration, seeking to maintain an average effective duration for the fixed-income portion of the Fund&amp;#146;s portfolio of 3 to 7 years. Duration is a measure of estimated price sensitivity relative to changes in interest rates. Portfolios with longer durations are typically more sensitive to changes in interest rates. For example, if interest rates rise by 1%, the market value of a security with an effective duration of 3 years would decrease by 3%, with all other factors being constant. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt;</rr:StrategyNarrativeTextBlock>

In general, an issuer will call its bonds if they can be refinanced by issuing new bonds which bear a lower interest rate. The Fund may then be forced to invest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund&amp;#146;s income.&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Credit Risk: The issuers or guarantors of securities of fixed-income securities owned by the Fund may default on the payment of principal or interest, or experience a decline in credit quality, causing the value of the Fund to decrease. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;Growth Style Investing Risk: Different types of stocks tend to shift into and out of favor with stock market investors depending on market and economic conditions.

The proceeds received by the Fund from prepayments will likely be reinvested at interest rates lower than the original investment, thus resulting in a reduction of income to the Fund. Likewise, rising interest rates could reduce prepayments and extend the life of securities with lower interest rates, which may increase the sensitivity of the Fund&amp;#146;s value to rising interest rates. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

Within the selected industries and sectors, the Adviser invests in foreign growth-oriented companies it believes exhibit the potential for superior growth. The Adviser believes that a company&amp;#8217;s earnings growth is the primary determinant of its potential long-term return and evaluates a company's potential for above average long-term earnings and revenue growth.&lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;Several factors are considered in the Adviser&amp;#8217;s evaluation of a company, including:&lt;/font&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;unique product or service,&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;growing product demand,&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;dominant and growing market share,&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;management experience and capabilities, and&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;strong financial condition.&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;When selling equity securities for the Fund, the Adviser considers several factors, including changes in a company's fundamentals and anticipated earnings.&lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund invests in common stocks of issuers domiciled in at least three foreign countries. As of September 30, 2012, the Fund was invested in common stocks of companies domiciled in 23 foreign countries. Up to 50% of the Fund's total assets may be invested in equity securities of small-to medium-sized emerging growth companies in developed markets (such as Germany and Japan) and developing markets (such as Thailand and Brazil). Small companies generally have a capitalization of under $3.0 billion, and medium-sized companies generally have capitalizations between $2 and $15 billion. Emerging growth companies are small-and medium-sized companies that the Adviser believes have a potential for earnings growth over time that is above the growth rate of more established companies or are early in their life cycles.&lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund may invest in securities representing underlying international securities such as sponsored American Depository Receipts, European Depository Receipts and Global Depository Receipts.&lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;In order to hedge against adverse movements in currency exchange rates, the Fund may from time to time enter into forward foreign currency exchange contracts.&lt;/font&gt;</rr:StrategyNarrativeTextBlock>
