Fundamental Investors^®

Semi-annual report for the six months ended June 30, 2013

Fundamental Investors seeks long-term growth of capital and income.

This fund is one of more than 40 offered by one of the nation’s largest mutual fund families, American Funds, from Capital Group. For more than 80 years, Capital has invested with a long-term focus based on thorough research and attention to risk.

Fund results shown in this report, unless otherwise indicated, are for Class A shares at net asset value. If a sales charge (maximum 5.75%) had been deducted, the results would have been lower. Results are for past periods and are not predictive of results for future periods. Current and future results may be lower or higher than those shown. Share prices and returns will vary, so investors may lose money. Investing for short periods makes losses more likely. Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value. For current information and month-end results, visit americanfunds.com.

Here are the average annual total returns on a $1,000 investment with all distributions reinvested for periods ended June 30, 2013:

Class A shares	1 year		5 years		10 years
Reflecting 5.75% maximum sales charge		15.52%		3.83%		8.79%

For other share class results, visit americanfunds.com and americanfundsretirement.com.

The total annual fund operating expense ratio was 0.65% for Class A shares as of the prospectus dated March 1, 2013.

Investment results assume all distributions are reinvested and reflect applicable fees and expenses. When applicable, investment results reflect fee waivers, without which results would have been lower. Visit americanfunds.com for more information.

Investing outside the United States may be subject to risks, such as currency fluctuations, periods of illiquidity and price volatility. These risks may be heightened in connection with investments in developing countries. Refer to the fund prospectus and the Risk Factors section of this report for more information on these and other risks associated with investing in the fund.

Fellow investors:

For the six months ended June 30, 2013, Fundamental Investors gained 12.5%. This return includes quarterly dividends totaling 25 cents a share paid during the period.

Despite this excellent gain, the fund’s results trailed those of its primary benchmark, the unmanaged Standard & Poor’s 500 Composite Index, which surged 13.8%. However, the fund meaningfully outpaced its growth-and-income fund peers, as measured by the Lipper Growth and Income Funds Index, which advanced 10.8%.

As a group, stock markets worldwide lagged the U.S. market. The unmanaged MSCI World Index, a measure of stock markets in more than 20 developed nations, returned 8.4%.

The U.S. leads the way

The start of the year showed U.S. stocks extending the strong gains seen in 2012. Generally healthy economic data and robust corporate earnings helped markets shrug off the effects of the government sequester and worries that surfaced in late May over whether the Federal Reserve would begin curtailing its asset-purchase program.

Japanese stocks drew considerable attention, rallying on the Bank of Japan’s announcement that it would implement aggressive quantitative easing plans.

Despite a highly challenging environment, European stocks held up relatively well. Investors cheered the European Central Bank’s interest rate cut, as well as signs that some of the region’s harsh austerity measures would be softened.

Results for the non-U.S. portion of the portfolio were hampered by the strengthening dollar, which appreciated against all major currencies and eroded returns for U.S.-based investors in companies domiciled abroad. (When the dollar strengthens, shares of companies denominated in other currencies lose value when translated into greenbacks.)

The impact of non-U.S. investments

While Fundamental Investors is able to invest up to 35% of its assets in companies domiciled abroad, less than 15% of the fund’s holdings were in stocks of such companies as of June 30, 2013. Even though that is well below the fund’s average over the past decade, non-U.S. holdings nonetheless acted as a drag on results, as they have over the most recent five-year period.

In light of this, it’s important to review the rationale and benefit of continuing to seek investments on a global scale. The principal reason for doing so is that it expands the universe of investment opportunities. The reality of today’s economy is that market leaders hail from many nations, and a global approach enables the fund’s managers to assemble a portfolio housing their highest conviction investment ideas. Importantly, notwithstanding the last few years, during the past decade the fund’s non-U.S. holdings — as a group — outpaced their domestic counterparts. It is with recognition that markets move in cycles and the belief that significant opportunity exists among companies domiciled abroad that we maintain our global approach.

Large holdings help drive returns, again

Although macroeconomic factors influenced results, stock selection among large holdings also drove returns. It’s a theme we regularly come back to in these reports, as the fund’s long-term success has been built on a diverse portfolio of well-researched, high-conviction companies drawn from multiple sectors and industries.

Fundamental Investors’ 10 largest holdings
(as of June 30, 2013)

Company	Percent of net assets
Home Depot		3.03	%
Amazon		2.62
Boeing		2.15
Google		2.05
Microsoft		1.98
Merck		1.64
Citigroup		1.53
Taiwan Semiconductor		1.53
Time Warner		1.51
Union Pacific		1.50

For the six months, seven of the fund’s top 10 positions fared significantly better than the S&P 500. Home Depot (25.3%), the largest holding, continued to see significant earnings growth thanks in part to a strengthening U.S. housing market; the company meaningfully raised its financial projections. Boeing (35.9%) overcame concerns related to the temporary grounding of its Dreamliner aircraft to post a significant gain.

Microsoft (29.2%), Google (24.1%), Union Pacific (22.7%), Citigroup (21.3%) and Time Warner (20.9%) also notched substantial increases. Results for Merck (13.5%) were roughly in line with the market. Only Amazon (10.6%) and Taiwan Semiconductor Manufacturing (8.1%) lagged the index, though both turned in solid absolute results.

Other large holdings posting exceptional results included Gilead Sciences (39.4%), American Express (30.1%) and Disney (26.8%).

There were a few disappointments. Web services provider Rackspace Hosting (–49.0%) saw its share price cut in half as earnings results and projections disappointed investors. Suncor Energy (–10.4%) stumbled on weakness in the energy sector and a strengthening dollar. And though Apple (–25.7%) continued to lose ground, timely and substantial reductions in our investment mitigated the impact of the downturn.

Additions and outlook

During the six months, we significantly added to our holdings in the financials area as we believe that steady economic improvement could have a positive impact on earnings and dividends.

Fundamental Investors 3

We also continued to build positions among aerospace companies, specifically the biggest manufacturers of commercial aircraft, Boeing and EADS (more commonly known as Airbus). We expect that both could benefit from expanding commercial air travel and a very large backlog of orders for the fuel-efficient models that airlines increasingly demand.

Over the last three years, the market, as measured by the S&P 500, has appreciated more than 65% on a cumulative basis. And while we don’t see imminent pitfalls or have a bearish outlook, we would not be surprised if there was a pause in the upward trend. Yet this view does not mean we disengage from the market. Rather, we continue to believe that whatever the investment backdrop, fundamental research will uncover companies that can help the fund pursue its objectives.

It’s this approach upon which the fund’s long-term results, as represented by the 10-year and lifetime returns in the table on page 1, have been built.

We thank you for your commitment to Fundamental Investors.

Sincerely,

James F. Rothenberg	Dina N. Perry

For current information about the fund, visit americanfunds.com.

The fund’s 30-day yield for Class A shares as of July 31, 2013, calculated in accordance with the U.S. Securities and Exchange Commission (SEC) formula, was 1.21%. The fund’s 12-month distribution rate for Class A shares as of that date was 1.29%. Both reflect the 5.75% maximum sales charge. The SEC yield reflects the rate at which the fund is earning income on its current portfolio of securities while the distribution rate reflects the fund’s past dividends paid to shareholders. Accordingly, the fund’s SEC yield and distribution rate may differ.

1. Organization

American Funds Fundamental Investors (the “trust”) is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company and has initially issued one series of shares, Fundamental Investors (the “fund”). The fund seeks long-term growth of capital and income.

The fund has 16 share classes consisting of five retail share classes (Classes A, B and C, as well as two F share classes, F-1 and F-2), five 529 college savings plan share classes (Classes 529-A, 529-B, 529-C, 529-E and 529-F-1) and six retirement plan share classes (Classes R-1, R-2, R-3, R-4, R-5 and R-6). The 529 college savings plan share classes can be used to save for college education. The retirement plan share classes are generally offered only through eligible employer-sponsored retirement plans. The fund’s share classes are further described below:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Classes A and 529-A	Up to 5.75%	None (except 1% for certain redemptions within one year of purchase without an initial sales charge)	None
Classes B and 529-B*	None	Declines from 5% to 0% for redemptions within six years of purchase	Classes B and 529-B convert to Classes A and 529-A, respectively, after eight years
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F-1 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Classes F-1, F-2 and 529-F-1	None	None	None
Classes R-1, R-2, R-3, R-4, R-5 and R-6	None	None	None

* Class B and 529-B shares of the fund are not available for purchase.

Holders of all share classes have equal pro rata rights to assets, dividends and liquidation proceeds. Each share class has identical voting rights, except for the exclusive right to vote on matters affecting only its class. Share classes have different fees and expenses (“class-specific fees and expenses”), primarily due to different arrangements for distribution, administrative and shareholder services. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different per-share dividends by each share class.

2. Significant accounting policies

The financial statements have been prepared to comply with accounting principles generally accepted in the United States of America. These principles require management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates. The fund follows the significant accounting policies described below, as well as the valuation policies described in the next section on valuation.

Security transactions and related investment income — Security transactions are recorded by the fund as of the date the trades are executed with brokers. Realized gains and losses from security transactions are determined based on the specific identified cost of the securities. In the event a security is purchased with a delayed payment date, the fund will segregate liquid assets sufficient to meet its payment obligations. Dividend income is recognized on the ex-dividend date and interest income is recognized on an accrual basis. Market discounts, premiums and original issue discounts on fixed-income securities are amortized daily over the expected life of the security.

Class allocations — Income, fees and expenses (other than class-specific fees and expenses) and realized and unrealized gains and losses are allocated daily among the various share classes based on their relative net assets. Class-specific fees and expenses, such as distribution, administrative and shareholder services, are charged directly to the respective share class.

Dividends and distributions to shareholders — Dividends and distributions to shareholders are recorded on the ex-dividend date.

Currency translation — Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars at the exchange rates supplied by one or more pricing vendors on the valuation date. Purchases and sales of investment securities and income and expenses are translated into U.S. dollars at the exchange rates on the dates of such transactions. On the accompanying financial statements, the effects of changes in exchange rates on

14 Fundamental Investors

investment securities are included with the net realized gain or loss and net unrealized appreciation or depreciation on investments. The realized gain or loss and unrealized appreciation or depreciation resulting from all other transactions denominated in currencies other than U.S. dollars are disclosed separately.

3. Valuation

Capital Research and Management Company (“CRMC”), the fund’s investment adviser, values the fund’s investments at fair value as defined by accounting principles generally accepted in the United States of America. The net asset value of each share class of the fund is generally determined as of approximately 4:00 p.m. New York time each day the New York Stock Exchange is open.

Methods and inputs — The fund’s investment adviser uses the following methods and inputs to establish the fair value of the fund’s assets and liabilities. Use of particular methods and inputs may vary over time based on availability and relevance as market and economic conditions evolve.

Equity securities are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

Fixed-income securities, including short-term securities purchased with more than 60 days left to maturity, are generally valued at prices obtained from one or more pricing vendors. Vendors value such securities based on one or more of the inputs described in the table on the following page. The table provides examples of inputs that are commonly relevant for valuing particular classes of fixed-income securities in which the fund is authorized to invest. However, these classifications are not exclusive, and any of the inputs may be used to value any other class of fixed-income security.

Fundamental Investors 15

Fixed-income class	Examples of standard inputs
All	Benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, spreads and other relationships observed in the markets among comparable securities; and proprietary pricing models such as yield measures calculated using factors such as cash flows, financial or collateral performance and other reference data (collectively referred to as “standard inputs”)
Corporate bonds & notes; convertible securities	Standard inputs and underlying equity of the issuer
Bonds & notes of governments & government agencies	Standard inputs and interest rate volatilities
Mortgage-backed; asset-backed obligations	Standard inputs and cash flows, prepayment information, default rates, delinquency and loss assumptions, collateral characteristics, credit enhancements and specific deal information

When the fund’s investment adviser deems it appropriate to do so (such as when vendor prices are unavailable or not deemed to be representative), fixed-income securities will be valued in good faith at the mean quoted bid and ask prices that are reasonably and timely available (or bid prices, if ask prices are not available) or at prices for securities of comparable maturity, quality and type.

Securities with both fixed-income and equity characteristics, or equity securities traded principally among fixed-income dealers, are generally valued in the manner described above for either equity or fixed-income securities, depending on which method is deemed most appropriate by the fund’s investment adviser. Short-term securities purchased within 60 days to maturity are valued at amortized cost, which approximates fair value. The value of short-term securities originally purchased with maturities greater than 60 days is determined based on an amortized value to par when they reach 60 days.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the fund’s investment adviser are fair valued as determined in good faith under fair valuation guidelines adopted by authority of the fund’s board of trustees as further described below. The investment adviser follows fair valuation guidelines, consistent with U.S. Securities and Exchange Commission rules and guidance,

16 Fundamental Investors

to consider relevant principles and factors when making fair value determinations. The investment adviser considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security; contractual or legal restrictions on resale of the security; relevant financial or business developments of the issuer; actively traded similar or related securities; conversion or exchange rights on the security; related corporate actions; significant events occurring after the close of trading in the security; and changes in overall market conditions. In addition, the closing prices of equity securities that trade in markets outside U.S. time zones may be adjusted to reflect significant events that occur after the close of local trading but before the net asset value of each share class of the fund is determined. Fair valuations and valuations of investments that are not actively trading involve judgment and may differ materially from valuations that would have been used had greater market activity occurred.

Processes and structure — The fund’s board of trustees has delegated authority to the fund’s investment adviser to make fair value determinations, subject to board oversight. The investment adviser has established a Joint Fair Valuation Committee (the “Fair Valuation Committee”) to administer, implement and oversee the fair valuation process, and to make fair value decisions. The Fair Valuation Committee regularly reviews its own fair value decisions, as well as decisions made under its standing instructions to the investment adviser’s valuation teams. The Fair Valuation Committee reviews changes in fair value measurements from period to period and may, as deemed appropriate, update the fair valuation guidelines to better reflect the results of back testing and address new or evolving issues. The Fair Valuation Committee reports any changes to the fair valuation guidelines to the board of trustees with supplemental information to support the changes. The fund’s board and audit committee also regularly review reports that describe fair value determinations and methods.

The fund’s investment adviser has also established a Fixed-Income Pricing Review Group to administer and oversee the fixed-income valuation process, including the use of fixed-income pricing vendors. This group regularly reviews pricing vendor information and market data. Pricing decisions, processes and controls over security valuation are also subject to additional internal reviews, including an annual control self-evaluation program facilitated by the investment adviser’s compliance group.

Fundamental Investors 17

Classifications — The fund’s investment adviser classifies the fund’s assets and liabilities into three levels based on the inputs used to value the assets or liabilities. Level 1 values are based on quoted prices in active markets for identical securities. Level 2 values are based on significant observable market inputs, such as quoted prices for similar securities and quoted prices in inactive markets. Certain securities trading outside the U.S. may transfer between Level 1 and Level 2 due to valuation adjustments resulting from significant market movements following the close of local trading. Level 3 values are based on significant unobservable inputs that reflect the investment adviser’s determination of assumptions that market participants might reasonably use in valuing the securities. The valuation levels are not necessarily an indication of the risk or liquidity associated with the underlying investment. For example, U.S. government securities are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market. The following table presents the fund’s valuation levels as of June 30, 2013 (dollars in thousands):

	Investment securities
	Level 1*		Level 2		Level 3		Total

* Securities with a market value of $4,063,698,000, which represented 6.96% of the net assets of the fund, transferred from Level 2 to Level 1 since the prior fiscal year-end, primarily due to a lack of significant market movements following the close of local trading.

4. Risk factors

Investing in the fund may involve certain risks including, but not limited to, those described below.

Market conditions — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline due to market conditions and other factors, including those directly involving the issuers of securities held by the fund.

Investing in growth-oriented stocks — Growth-oriented stocks may involve larger price swings and greater potential for loss than other types of investments.

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 at, the companies in which the fund invests.

Investing outside the U.S. — Securities of issuers domiciled outside the U.S., or with significant operations outside the U.S., 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 U.S. Investments outside the U.S. may also be subject to different settlement and accounting practices and different regulatory, legal and reporting standards, and may be more difficult to value, than those in the U.S. The risks of investing outside the U.S. 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.

5. Taxation and distributions

Federal income taxation — The fund complies with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and intends to distribute substantially all of its net taxable income and net capital gains each year. The fund is not subject to income taxes to the extent such distributions are made. Therefore, no federal income tax provision is required.

As of and during the period ended June 30, 2013, the fund did not have a liability for any unrecognized tax benefits. The fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the statement of operations. During the period, the fund did not incur any interest or penalties.

The fund is not subject to examination by U.S. federal tax authorities for tax years before 2009, by state tax authorities for tax years before 2008 and by tax authorities outside the U.S. for tax years before 2006.

Non-U.S. taxation — Dividend income is recorded net of non-U.S. taxes paid. Gains realized by the fund on the sale of securities in certain countries are subject to non-U.S. taxes. The fund records a liability based on unrealized gains to provide for potential non-U.S. taxes payable upon the sale of these securities.

Distributions — Distributions paid to shareholders are based on net investment income and net realized gains determined on a tax basis, which may differ from net investment income and net realized gains for financial reporting purposes. These differences are due primarily to different treatment for items such as currency gains and losses; short-term capital gains and losses; capital losses related to sales of certain securities within 30 days of purchase; and net capital losses. The fiscal year in which amounts are distributed may differ from the year in which the net investment income and net realized gains are recorded by the fund for financial reporting purposes.

20 Fundamental Investors

The components of distributable earnings on a tax basis are reported as of the fund’s most recent year-end. As of December 31, 2012, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed ordinary income	$	213,279
Capital loss carryforward expiring 2017*		(1,821,616	)

* The capital loss carryforward will be used to offset any capital gains realized by the fund in the current year or in subsequent years through the expiration date. The fund will not make distributions from capital gains while a capital loss carryforward remains.

Under the Regulated Investment Company Modernization Act of 2010 (the “Act”), net capital losses recognized after December 31, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

As of June 30, 2013, the tax basis unrealized appreciation (depreciation) and cost of investment securities were as follows (dollars in thousands):

Gross unrealized appreciation on investment securities	$	17,138,914
Gross unrealized depreciation on investment securities		(753,195	)
Net unrealized appreciation on investment securities		16,385,719
Cost of investment securities		41,926,510

6. Fees and transactions with related parties

CRMC, the fund’s investment adviser, is the parent company of American Funds Distributors,^® Inc. (“AFD”), the principal underwriter of the fund’s shares, and American Funds Service Company^® (“AFS”), the fund’s transfer agent. CRMC, AFD and AFS are considered related parties to the fund.

Investment advisory services — The fund has an investment advisory and service agreement with CRMC that provides for monthly fees accrued daily. These fees are based on a series of decreasing annual rates beginning with 0.390% on the first $1 billion of daily net assets and decreasing to 0.232% on such assets in excess of $55 billion. For the six months ended June 30, 2013, the investment advisory services fee was $70,383,000, which was equivalent to an annualized rate of 0.250% of average daily net assets.

22 Fundamental Investors

Class-specific fees and expenses — Expenses that are specific to individual share classes are accrued directly to the respective share class. The principal class-specific fees and expenses are described below:

Distribution services — The fund has plans of distribution for all share classes, except Class F-2, R-5 and R-6 shares. Under the plans, the board of trustees approves certain categories of expenses that are used to finance activities primarily intended to sell fund shares and service existing accounts. The plans provide for payments, based on an annualized percentage of average daily net assets, ranging from 0.25% to 1.00% as noted below. In some cases, the board of trustees has limited the amounts that may be paid to less than the maximum allowed by the plans. All share classes with a plan may use up to 0.25% of average daily net assets to pay service fees, or to compensate AFD for paying service fees, to firms that have entered into agreements with AFD to provide certain shareholder services. The remaining amounts available to be paid under each plan are paid to dealers to compensate them for their sales activities.

For Class A and 529-A shares, distribution-related expenses include the reimbursement of dealer and wholesaler commissions paid by AFD for certain shares sold without a sales charge. These share classes reimburse AFD for amounts billed within the prior 15 months but only to the extent that the overall annual expense limit of 0.25% is not exceeded. As of June 30, 2013, there were no unreimbursed expenses subject to reimbursement for Class A or 529-A shares.

Share class	Currently approved limits			Plan limits
Class A		0.25	%		0.25	%
Class 529-A		0.25			0.50
Classes B and 529-B		1.00			1.00
Classes C, 529-C and R-1		1.00			1.00
Class R-2		0.75			1.00
Classes 529-E and R-3		0.50			0.75
Classes F-1, 529-F-1 and R-4		0.25			0.50

Transfer agent services — The fund has a shareholder services agreement with AFS under which the fund compensates AFS for providing transfer agent services to each of the fund’s share classes. These services include recordkeeping, shareholder communications and transaction processing. In addition, the fund reimburses AFS for amounts paid to third parties for performing transfer agent services on behalf of fund shareholders.

Administrative services — The fund has an administrative services agreement with CRMC under which the fund compensates CRMC for providing administrative services to Class A, C, F, 529 and R shares. These services include, but are not limited to, coordinating, monitoring, assisting and overseeing third parties that provide services to fund shareholders. Under the agreement, Class A shares pay an annual fee of 0.01% and Class C, F, 529 and R shares pay an annual fee of 0.05% of their respective average daily net assets.

529 plan services — Each 529 share class is subject to service fees to compensate the Commonwealth of Virginia for the maintenance of the 529 college savings plan. The quarterly fee is based on a series of decreasing annual rates beginning with 0.10% on the first $30 billion of the net assets invested in Class 529 shares of the American Funds and decreasing to 0.06% on such assets between $120 billion and $150 billion. The fee for any given calendar quarter is accrued and calculated on the basis of the average net assets of Class 529 shares of the American Funds for the last month of the prior calendar quarter. The fee is included in other expenses on the accompanying financial statements. The Commonwealth of Virginia is not considered a related party.

Expense example unaudited

As a shareholder of the fund, you incur two types of costs: (1) transaction costs, such as initial sales charges on purchase payments and contingent deferred sales charges on redemptions (loads), and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund so you can compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period (January 1, 2013, through June 30, 2013).

Actual expenses:

The first line of each share class in the table on the next page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses paid during period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes:

The second line of each share class in the table on the next page provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio for the share class and an assumed rate of return of 5.00% per year before expenses, which is not the actual return of the share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5.00% hypothetical example with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Notes:

There are some account fees that are charged to certain types of accounts, such as individual retirement accounts and 529 college savings plan accounts (generally, a $10 fee is charged to set up the account and an additional $10 fee is charged to the account annually), that would increase the amount of expenses paid on your account. In addition, retirement plan participants may be subject to certain fees charged by the plan sponsor, and Class F-1, F-2 and 529-F-1 shareholders may be subject to fees charged by financial intermediaries, typically ranging from 0.75% to 1.50% of assets annually depending on services offered. You can estimate the impact of these fees by adding the amount of the fees to the total estimated expenses you paid on your account during the period as calculated above. In addition, your ending account value would be lower by the amount of these fees.

Fundamental Investors 35

Note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of each share class in the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

ITEM 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 8 – Portfolio Managers of Closed-End Management Investment Companies

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 9 – Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 10 – Submission of Matters to a Vote of Security Holders

There have been no material changes to the procedures by which shareholders may recommend nominees to the Registrant’s board of trustees since the Registrant last submitted a proxy statement to its shareholders. The procedures are as follows. The Registrant has a nominating and governance committee comprised solely of persons who are not considered ‘‘interested persons’’ of the Registrant within the meaning of the Investment Company Act of 1940, as amended. The committee periodically reviews such issues as the board’s composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full board of trustees. While the committee normally is able to identify from its own resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on the board. Such suggestions must be sent in writing to the nominating and governance committee of the Registrant, c/o the Registrant’s Secretary, and must be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the nominating and governance committee.

ITEM 11 – Controls and Procedures

(a)	The Registrant’s Principal Executive Officer and Principal Financial Officer have concluded, based on their evaluation of the Registrant’s disclosure controls and procedures (as such term is defined in Rule 30a-3 under the Investment Company Act of 1940), that such controls and procedures are adequate and reasonably designed to achieve the purposes described in paragraph (c) of such rule.
(b)	There were no changes in the Registrant’s internal controls over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940) that occurred during the Registrant’s second fiscal quarter of the period covered by this report that has materially affected, or is reasonably likely to materially affect, the Registrant’s internal control over financial reporting.

ITEM 12 – Exhibits

(a)(1)	Not applicable for filing of semi-annual reports to shareholders.
(a)(2)	The certifications required by Rule 30a-2 of the Investment Company Act of 1940 and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are attached as exhibits hereto.
