A higher portfolio turnover rate &lt;br /&gt;may indicate higher transaction costs and may result in higher taxes when fund &lt;br /&gt;shares are held in a taxable account. These costs, which are not reflected in &lt;br /&gt;annual fund operating expenses or in the example, affect the fund&apos;s investment &lt;br /&gt;results.

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of &lt;br /&gt;the funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time. &lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure &lt;br /&gt;may result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit &lt;br /&gt;of the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline due&lt;br /&gt;to market conditions and other factors, including those directly involving the&lt;br /&gt;issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests. These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. &lt;br /&gt;In addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the&lt;br /&gt;underlying funds are subject to the risk that the methods and analyses employed&lt;br /&gt;by the investment adviser in this process may not produce the desired results.&lt;br /&gt;This could cause an underlying fund to lose value or its investment results to&lt;br /&gt;lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person. You should consider how this fund &lt;br /&gt;fits into your overall investment program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of &lt;br /&gt;the funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach&lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Growt-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Equity-income and balanced funds 10%&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;60%&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;Retire 5&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure &lt;br /&gt;may result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit &lt;br /&gt;of the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline due&lt;br /&gt;to market conditions and other factors, including those directly involving the&lt;br /&gt;issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments.

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach &lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;Retire 5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&lt;br /&gt; &lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure &lt;br /&gt;may result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit &lt;br /&gt;of the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline &lt;br /&gt;due to market conditions and other factors, including those directly involving &lt;br /&gt;the issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or refinance &lt;br /&gt;a security before its stated maturity, which may result in the underlying fund &lt;br /&gt;having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the&lt;br /&gt;underlying funds are subject to the risk that the methods and analyses employed&lt;br /&gt;by the investment adviser in this process may not produce the desired results.&lt;br /&gt;This could cause an underlying fund to lose value or its investment results to&lt;br /&gt;lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person. You should consider how this fund &lt;br /&gt;fits into your overall investment program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time. &lt;br /&gt;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach&amp;#xA0;&amp;#xA0;&lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0% &lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit &lt;br /&gt;of the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline &lt;br /&gt;due to market conditions and other factors, including those directly involving &lt;br /&gt;the issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the&lt;br /&gt;underlying funds are subject to the risk that the methods and analyses employed&lt;br /&gt;by the investment adviser in this process may not produce the desired results.&lt;br /&gt;This could cause an underlying fund to lose value or its investment results to&lt;br /&gt;lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person. You should consider how this fund &lt;br /&gt;fits into your overall investment program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach &lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30 &lt;br /&gt;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit of&lt;br /&gt;the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline due&lt;br /&gt;to market conditions and other factors, including those directly involving the&lt;br /&gt;issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, &lt;br /&gt;may lose value because of adverse political, social, economic or market &lt;br /&gt;developments in the countries or regions in which the issuer operates. These &lt;br /&gt;securities may also lose value due to changes in foreign currency exchange rates &lt;br /&gt;against the U.S. dollar and/or currencies of other countries. Securities markets &lt;br /&gt;in certain countries may be more volatile and/or less liquid than those in the &lt;br /&gt;United States. Investments outside the United States may also be subject to &lt;br /&gt;different settlement and accounting practices and different regulatory, legal &lt;br /&gt;and reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the underlying &lt;br /&gt;funds are subject to the risk that the methods and analyses employed by the &lt;br /&gt;investment adviser in this process may not produce the desired results. This could &lt;br /&gt;cause an underlying fund to lose value or its investment results to lag relevant &lt;br /&gt;benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or guaranteed &lt;br /&gt;by the Federal Deposit Insurance Corporation or any other governmental agency, &lt;br /&gt;entity or person. You should consider how this fund fits into your overall investment &lt;br /&gt;program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach &lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&lt;br /&gt;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit of&lt;br /&gt;the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline due&lt;br /&gt;to market conditions and other factors, including those directly involving the&lt;br /&gt;issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or refinance &lt;br /&gt;a security before its stated maturity, which may result in the underlying fund &lt;br /&gt;having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, &lt;br /&gt;may lose value because of adverse political, social, economic or market &lt;br /&gt;developments in the countries or regions in which the issuer operates. These &lt;br /&gt;securities may also lose value due to changes in foreign currency exchange &lt;br /&gt;rates against the U.S. dollar and/or currencies of other countries. Securities &lt;br /&gt;markets in certain countries may be more volatile and/or less liquid than those &lt;br /&gt;in the United States. Investments outside the United States may also be subject &lt;br /&gt;to different settlement and accounting practices and different regulatory, legal &lt;br /&gt;and reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the&lt;br /&gt;underlying funds are subject to the risk that the methods and analyses employed&lt;br /&gt;by the investment adviser in this process may not produce the desired results.&lt;br /&gt;This could cause an underlying fund to lose value or its investment results to&lt;br /&gt;lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or guaranteed &lt;br /&gt;by the Federal Deposit Insurance Corporation or any other governmental agency, &lt;br /&gt;entity or person. You should consider how this fund fits into your overall &lt;br /&gt;investment program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach&lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit of&lt;br /&gt;the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the bonds and&lt;br /&gt;other securities held by the underlying funds may decline due to market&lt;br /&gt;conditions and other factors, including those directly involving the issuers of&lt;br /&gt;securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the&lt;br /&gt;underlying funds are subject to the risk that the methods and analyses employed&lt;br /&gt;by the investment adviser in this process may not produce the desired results.&lt;br /&gt;This could cause an underlying fund to lose value or its investment results to&lt;br /&gt;lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person. You should consider how this fund fits&lt;br /&gt;into your overall investment program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach&lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40% &lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30 &lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit of&lt;br /&gt;the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the bonds and&lt;br /&gt;other securities held by the underlying funds may decline due to market&lt;br /&gt;conditions and other factors, including those directly involving the issuers of&lt;br /&gt;securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - The prices of securities of issuers&lt;br /&gt;domiciled outside the United States or with significant operations outside the&lt;br /&gt;United States may decline due to conditions specific to the countries or regions&lt;br /&gt;in which the issuer is domiciled or operates, including adverse political,&lt;br /&gt;social, economic or market changes in such countries or regions. The securities&lt;br /&gt;of issuers domiciled in certain countries outside the United States may be more&lt;br /&gt;volatile, less liquid and/or more difficult to value than those of U.S. issuers.&lt;br /&gt;Issuers in countries outside the United States may also be subject to different&lt;br /&gt;tax and accounting policies and different auditing, reporting, legal and&lt;br /&gt;regulatory standards. In addition, the value of investments outside the United&lt;br /&gt;States may be reduced by foreign taxes, including foreign withholding taxes on&lt;br /&gt;interest and dividends. Issuers in countries outside the United States may also&lt;br /&gt;be subject to different government and legal systems that make it difficult for&lt;br /&gt;the underlying fund to exercise its rights as a shareholder of the company.&lt;br /&gt;Further, there may be increased risks of delayed settlement of securities&lt;br /&gt;purchased or sold by an underlying fund. These investments may also be affected&lt;br /&gt;by changes in foreign currency exchange rates against the U.S. dollar and/or&lt;br /&gt;currencies of other countries. The risks of investing outside the United States&lt;br /&gt;may be heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages each underlying fund&apos;s investments. Consequently, the&lt;br /&gt;underlying funds are subject to the risk that the methods and analyses employed&lt;br /&gt;by the investment adviser in this process may not produce the desired results.&lt;br /&gt;This could cause an underlying fund to lose value or its investment results to&lt;br /&gt;lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person.

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund may be combined with other funds in a single&lt;br /&gt;portfolio with an investment allocation that will not evolve beyond that which&lt;br /&gt;is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach&lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30 &lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit of&lt;br /&gt;the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline due&lt;br /&gt;to market conditions and other factors, including those directly involving the&lt;br /&gt;issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages the underlying fund&apos;s investments. Consequently, the underlying&lt;br /&gt;funds are subject to the risk that the methods and analyses employed by the&lt;br /&gt;investment adviser in this process may not produce the desired results. This&lt;br /&gt;could cause an underlying fund to lose value or its investment results to lag&lt;br /&gt;relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person. You should consider how this fund fits&lt;br /&gt;into your overall investment program.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The underlying&lt;br /&gt;American Funds represent a variety of fund categories such as growth funds,&lt;br /&gt;growth-and-income funds, equity-income funds and a balanced fund and bond funds.&lt;br /&gt;The fund categories represent differing investment objectives. For example,&lt;br /&gt;growth funds seek long-term growth primarily through investing in both U.S.&lt;br /&gt;stocks and stocks of issuers domiciled outside the U.S. Growth-and-income funds&lt;br /&gt;seek long-term growth and income primarily through investments in stocks.&lt;br /&gt;Equity-income and balanced funds generally strive for income and growth through&lt;br /&gt;stocks and/or bond investments, while bond funds seek current income through&lt;br /&gt;bond investments.&lt;br /&gt; &lt;br /&gt;The investment adviser may periodically rebalance or modify the asset mix of the&lt;br /&gt;funds and change the underlying fund investments. According to its current&lt;br /&gt;investment approach, the investment adviser will continue to manage the fund for&lt;br /&gt;approximately thirty years after the fund reaches its target date. Thirty years&lt;br /&gt;after its target date, the fund&apos;s investment allocation will not evolve beyond&lt;br /&gt;that which is in effect at that time.&lt;br /&gt; &lt;br /&gt;The following chart illustrates the current investment approach of the fund by&lt;br /&gt;showing how its investment in the various fund categories will change over time.&lt;br /&gt; &lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Current investment approach&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Growth funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Growth-and-income funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;5%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;0%&lt;br /&gt;Equity-income and balanced funds&amp;#xA0;&amp;#xA0;&amp;#xA0;25%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;35%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;40%&lt;br /&gt;Bond funds&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;45%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;50%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;55%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;60%&amp;#xA0;&amp;#xA0;&lt;br /&gt;&lt;br /&gt;Years to retirement&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;Retire&amp;#xA0;&amp;#xA0;&amp;#xA0;5&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;10&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;15&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;20&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;25&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;30&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The investment adviser anticipates that the fund will invest its assets within a&lt;br /&gt;range that deviates no more than 10% above or below the investment approach set&lt;br /&gt;forth above. For example, a 40% target allocation to growth funds is not&lt;br /&gt;expected to be greater than 50% nor less than 30%.

You may lose money by investing in the fund. The&lt;br /&gt;likelihood of loss may be greater if you invest for a shorter period of time.&lt;br /&gt;Investors in the fund should have a long-term perspective and be able to&lt;br /&gt;tolerate potentially sharp declines in value.&lt;br /&gt; &lt;br /&gt;Allocation risk - Investments in the fund are subject to risks related to the&lt;br /&gt;investment adviser&apos;s allocation choices. The selection of the underlying funds&lt;br /&gt;and the allocation of the fund&apos;s assets could cause the fund to lose value or&lt;br /&gt;its results to lag relevant benchmarks or other funds with similar objectives.&lt;br /&gt;For investors who are close to or in retirement, the fund&apos;s equity exposure may&lt;br /&gt;result in investment volatility that could reduce an investor&apos;s available&lt;br /&gt;retirement assets at a time when the investor has a need to withdraw funds. For&lt;br /&gt;investors who are farther from retirement, there is a risk the fund may invest&lt;br /&gt;too much in investments designed to ensure capital conservation and current&lt;br /&gt;income, which may prevent the investor from meeting his or her retirement goals.&lt;br /&gt; &lt;br /&gt;Fund structure - The fund invests in underlying funds and incurs expenses&lt;br /&gt;related to the underlying funds. In addition, investors in the fund will incur&lt;br /&gt;fees to pay for certain expenses related to the operations of the fund. An&lt;br /&gt;investor holding the underlying funds directly and in the same proportions as&lt;br /&gt;the fund would incur lower overall expenses but would not receive the benefit of&lt;br /&gt;the portfolio management and other services provided by the fund.&lt;br /&gt; &lt;br /&gt;Because the fund&apos;s investments consist of underlying funds, the fund&apos;s risks are&lt;br /&gt;directly related to the risks of the underlying funds. For this reason, it is&lt;br /&gt;important to understand the risks associated with investing in the underlying&lt;br /&gt;funds.&lt;br /&gt; &lt;br /&gt;Market conditions - The prices of, and the income generated by, the common&lt;br /&gt;stocks, bonds and other securities held by the underlying funds may decline due&lt;br /&gt;to market conditions and other factors, including those directly involving the&lt;br /&gt;issuers of securities held by the underlying funds.&lt;br /&gt; &lt;br /&gt;Investing in stocks - Investing in stocks may involve larger price swings and&lt;br /&gt;greater potential for loss than other types of investments. As a result, the&lt;br /&gt;value of the underlying funds may be subject to sharp, short-term declines in&lt;br /&gt;value. Income provided by an underlying fund may be reduced by changes in the&lt;br /&gt;dividend policies of, and the capital resources available at, the companies in&lt;br /&gt;which the underlying fund invests.These risks will be more significant for the&lt;br /&gt;fund in the years preceding its target date because a greater proportion of the&lt;br /&gt;fund&apos;s assets will consist of underlying funds that primarily invest in stocks.&lt;br /&gt; &lt;br /&gt;Investing in bonds - Rising interest rates will generally cause the prices of&lt;br /&gt;bonds and other debt securities to fall. Longer maturity debt securities may be&lt;br /&gt;subject to greater price fluctuations than shorter maturity debt securities. In&lt;br /&gt;addition, falling interest rates may cause an issuer to redeem, call or&lt;br /&gt;refinance a security before its stated maturity, which may result in the&lt;br /&gt;underlying fund having to reinvest the proceeds in lower yielding securities.&lt;br /&gt; &lt;br /&gt;Bonds and other debt securities are subject to credit risk, which is the&lt;br /&gt;possibility that the credit strength of an issuer will weaken and/or an issuer&lt;br /&gt;of a debt security will fail to make timely payments of principal or interest&lt;br /&gt;and the security will go into default. Credit risk is gauged, in part, by the&lt;br /&gt;credit ratings of the securities in which the underlying fund invests. However,&lt;br /&gt;ratings are only the opinions of the rating agencies issuing them and are not&lt;br /&gt;guarantees as to credit quality or an evaluation of market risk. These risks&lt;br /&gt;will be more significant as the fund approaches and passes its target date&lt;br /&gt;because a greater proportion of the fund&apos;s assets will consist of underlying&lt;br /&gt;funds that primarily invest in bonds.&lt;br /&gt; &lt;br /&gt;Investing in lower rated bonds - Lower rated bonds and other lower rated debt&lt;br /&gt;securities generally have higher rates of interest and involve greater risk of&lt;br /&gt;default or price declines due to changes in the issuer&apos;s creditworthiness than&lt;br /&gt;those of higher quality debt securities. The market prices of these securities&lt;br /&gt;may fluctuate more than the prices of higher quality debt securities and may&lt;br /&gt;decline significantly in periods of general economic difficulty. These risks may&lt;br /&gt;be increased with respect to investments in bonds rated Ba1 or BB+ or below by&lt;br /&gt;Nationally Recognized Statistical Rating Organizations or unrated but determined&lt;br /&gt;by the underlying fund&apos;s investment adviser to be of equivalent quality. Such&lt;br /&gt;securities are considered speculative and are sometimes referred to as "junk&lt;br /&gt;bonds." The value of the underlying funds may be similarly affected.&lt;br /&gt; &lt;br /&gt;Investing outside the United States - Securities of issuers domiciled outside&lt;br /&gt;the United States, or with significant operations outside the United States, may&lt;br /&gt;lose value because of adverse political, social, economic or market developments&lt;br /&gt;in the countries or regions in which the issuer operates. These securities may&lt;br /&gt;also lose value due to changes in foreign currency exchange rates against the&lt;br /&gt;U.S. dollar and/or currencies of other countries. Securities markets in certain&lt;br /&gt;countries may be more volatile and/or less liquid than those in the United&lt;br /&gt;States. Investments outside the United States may also be subject to different&lt;br /&gt;settlement and accounting practices and different regulatory, legal and&lt;br /&gt;reporting standards, and may be more difficult to value, than those in the&lt;br /&gt;United States. The risks of investing outside the United States may be&lt;br /&gt;heightened in connection with investments in emerging markets.&lt;br /&gt; &lt;br /&gt;Management - The investment adviser to the fund and to the underlying funds&lt;br /&gt;actively manages the underlying fund&apos;s investments. Consequently, the underlying&lt;br /&gt;funds are subject to the risk that the methods and analyses employed by the&lt;br /&gt;investment adviser in this process may not produce the desired results. This&lt;br /&gt;could cause an underlying fund to lose value or its investment results to lag&lt;br /&gt;relevant benchmarks or other funds with similar objectives.&lt;br /&gt; &lt;br /&gt;Your investment in the fund is not a bank deposit and is not insured or&lt;br /&gt;guaranteed by the Federal Deposit Insurance Corporation or any other&lt;br /&gt;governmental agency, entity or person.
