Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example INVESTMENT CO OF AMERICA® (USD $)	1 year	3 years	5 years	10 years
Class A	634	759	896	1,293
Class B	639	834	950	1,438
Class C	244	446	771	1,691
Class F-1	69	218	379	847
Class F-2	42	132	230	518
Class 529-A	663	828	1,006	1,512
Class 529-B	672	913	1,076	1,678
Class 529-C	271	510	870	1,879
Class 529-E	117	342	584	1,270
Class 529-F-1	70	197	333	723

Class R-4	66	208	362	810
Class R-5	36	113	197	443
Class R-6	31	97	169	381

For the share classes listed below, you would pay the following if you did not redeem your shares:

Class 529-B	172	513	876	1,678
Class 529-C	171	510	870	1,879

Portfolio turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 24% of the average value of its portfolio.

Principal investment strategies

The fund invests primarily in common stocks, most of which have a history of paying dividends. The fund’s investments are limited to securities of companies that are included on its eligible list. In light of the fund’s investment objectives and policies, securities are added to, or deleted from, the eligible list by the fund’s board of trustees after reviewing and acting upon the recommendations of the fund’s investment adviser. The investment adviser bases its recommendations on a number of factors, such as the fund’s investment objectives and policies, whether a company is considered a leader in its industry and a company’s dividend payment prospects. Although the fund focuses on investments in medium to larger capitalization companies, the fund’s investments are not limited to a particular capitalization size. In the selection of common stocks and other securities for investment, potential for capital appreciation and future dividends are given more weight than current yield.

The fund may invest up to 15% of its assets, at the time of purchase, in securities of issuers domiciled outside the United States.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers who decide how their respective segments will be invested.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Principal risks

This section describes the principal risks associated with the fund’s principal investment strategies. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time. Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

Market conditions — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline in response to certain events taking place around the world, including those directly involving the issuers of securities held by the fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; governmental or governmental agency responses to economic conditions; and currency, interest rate and commodity price fluctuations.

Investing in income-oriented stocks — Income provided by the fund may be reduced by changes in the dividend policies of, and the capital resources available for dividend payments at, the companies in which the fund invests.

Investing in growth-oriented stocks — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments.

Investing outside the United States — Securities of issuers domiciled outside the United States, or with significant operations outside the United States, may lose value because of adverse political, social, economic or market developments in the countries or regions in which the issuers operate. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different accounting practices and different regulatory, legal and reporting standards, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the investment adviser in this process may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

Investment results

The following bar chart shows how the fund’s investment results have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compare with different broad measures of market results. This information provides some indication of the risks of investing in the fund. The Lipper Growth & Income Funds Index includes the fund and other funds that disclose investment objectives and/or strategies reasonably comparable to the fund’s objective and/or strategies.

After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary. After-tax returns are calculated using the highest individual federal income tax rates in effect during each year of the periods shown and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation and likely will differ from the results shown above. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-favored arrangement, such as a 401(k) plan, individual retirement account (IRA) or 529 college savings plan.
