Under normal conditions, the fund&amp;#146;s allocation to the broad asset classes will be within the following ranges: stocks (70%-90%) and bonds and money markets (10-30%). When deciding upon allocations within these prescribed limits, we may favor fixed income securities if the economy is expected to slow sufficiently to hurt corporate profit growth.

The fund&amp;#146;s share price fluctuates, which means you could lose money by investing in the fund. The fund has partial exposure to a variety of risks in proportion to the amount it invests in stocks, bonds, and money market securities. The principal risks of investing in this fund are summarized as follows:&lt;br/&gt;&lt;br/&gt;&lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Asset allocation risk&lt;/font&gt; The fund&amp;#146;s overall allocations to stocks and bonds, and the allocations to the various asset classes and market sectors within those broad categories, could cause the fund to underperform other funds with a similar investment objective.&lt;br/&gt;&lt;br/&gt;&lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Risks of stock investing&lt;/font&gt;  Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The value of a stock in which the fund invests may decline due to general weakness in the stock market or because of factors that affect a company or a particular industry.&lt;br/&gt;&lt;br/&gt;Small- and medium-sized companies often have less experienced management, more limited financial resources, and less publicly available information than larger companies. Stocks of smaller companies may have limited trading markets and tend to be more sensitive to changes in overall economic conditions. To the extent the fund invests in companies that derive their profits from commodities and other real assets, it is subject to the risk that periods of low inflation will lessen relative returns and cause the fund to underperform other comparable stock funds.&lt;br/&gt;&lt;br/&gt;&lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Risks of bond and money market investing&lt;/font&gt; Bonds and money market securities have three main sources of risk. &lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Interest rate risk&lt;/font&gt; is the risk that a rise in interest rates will cause the price of a debt security held by the fund to fall. Securities with longer maturities typically suffer greater declines than those with shorter maturities. Mortgage-backed securities can react somewhat differently to interest rate changes because falling rates can cause losses of principal due to increased mortgage prepayments and rising rates can lead to decreased prepayments and greater volatility. &lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Credit risk&lt;/font&gt; is the risk that an issuer of a debt security will default (fail to make scheduled interest or principal payments), potentially reducing the fund&amp;#146;s income level and share price. This risk is increased when a security is downgraded or the perceived creditworthiness of the issuer deteriorates. &lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Liquidity risk&lt;/font&gt;&lt;font style="font-family:Serif; font-style:normal; font-weight:bold"&gt; &lt;/font&gt;is the risk that the fund may not be able to sell a holding in a timely manner or at a desired price. &lt;br/&gt;&lt;br/&gt;While the fund&amp;#146;s bond investments are expected to primarily be investment-grade, the fund may invest in bonds that are rated below investment-grade, also known as high yield or &amp;#147;junk&amp;#148; bonds, including those with the lowest credit rating. High yield bond issuers are more likely to suffer an adverse change in financial condition that  would result in the inability to meet a financial obligation. Accordingly, the securities they issue carry a higher risk of default and should be considered speculative. The fund&amp;#146;s exposure to credit risk, in particular, is increased to the extent it invests in high yield bonds. &lt;br/&gt;&lt;br/&gt;&lt;font style="font-family:Serif; font-style:italic; font-weight:bold"&gt;Foreign investing risk&lt;/font&gt; This is the risk that the fund&amp;#146;s investments in foreign securities may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar. These risks are heightened for the fund&amp;#146;s investments in emerging markets.&lt;/font&gt;</rr:RiskNarrativeTextBlock>
