Figures shown in this report are past results for Class A shares and are not predictive of results in future periods. Current and future results may be lower or higher than those shown. Investment returns will vary. Although the funds seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the funds. 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. For current information and month-end results, visit americanfunds.com.

The total annual fund operating expense ratios for Class A shares as of the most recent fiscal year-end were 0.51% for The Cash Management Trust of America, 0.57% for The U.S. Treasury Money Fund of America and 0.51% for The Tax-Exempt Money Fund of America. These figures do not reflect any fee waivers currently in effect; therefore the actual expense ratios are lower.

Fellow shareholders:

The past six months were marked by a decline in short-term interest rates as the Federal Reserve continued its efforts to stabilize the economy. Concerns about the housing slump and the strength of the U.S. economy overall deepened throughout the period. As a result, investors continued to flock to the relative safety of U.S. Treasury securities.

For the period ended March 31, 2008, the returns on The Cash Management Trust of America, The U.S. Treasury Money Fund of America and The Tax-Exempt Money Fund of America reflected the decline in short-term interest rates. All three maintained a constant net asset value of $1.00 per share.

The funds’ results

The Cash Management Trust of America produced an income return of 1.88% (3.76% annualized), with dividends reinvested, for the six months ended March 31, 2008. The fund’s annualized seven-day SEC yield as of that date was 2.12%.

The U.S. Treasury Money Fund of America generated an income return of 1.43% (2.86% annualized), including reinvested dividends, for the period. Because all of the fund’s earnings are derived from investments in U.S. Treasury securities, the income paid by the fund is exempt from state and local taxes. The fund’s annualized seven-day SEC yield at March 31, 2008, was 1.47%. The difference between the yields of the two taxable money market funds reflects the increased demand for Treasury bills during the recent period of financial market uncertainty.

The Tax-Exempt Money Fund of America provided a federally tax-free income return of 1.29% (2.58% annualized), with dividends reinvested, at the six months ended March 31, 2008. The income return is equivalent to a taxable return of 1.98% (3.96% annualized) for investors in the 35.0% tax bracket. A portion of this return may also be exempt from some state and local taxes. The fund’s annualized seven-day SEC yield at the end of the period was 1.47%, and its taxable equivalent annualized seven-day SEC yield was 2.26%.

Your funds’ annualized seven-day SEC yields as of March 31, 2008

Seven-day yield: Unlike a fund’s income return, which reflects income generated over the period, the seven-day SEC yield is calculated by annualizing dividends paid by a fund during the last seven days. This calculation more accurately reflects a fund’s current earnings.

1Represents the fund’s taxable equivalent yield calculated at the maximum effective 35.0% federal tax rate.

2Equivalent to Securities and Exchange Commission (SEC) yields. Represents the seven-day month-end averages.

3Because income paid by The U.S. Treasury Money Fund of America is exempt from state and local taxes in most states, the fund’s taxable equivalent yield would be higher than the rates shown in the chart.

The Fed and the economy

To help support the weakening economy, alleviate investor concerns and assist troubled financial institutions, the Federal Reserve continued to slash its key lending rate, lowering it to 2.00% (as of April 30). The Fed’s actions allayed some of the market’s stress by making it easier for banks to borrow short-term money and repair balance sheets bruised by problem loans.

Market conditions resulted in some shifts in the composition of The Cash Management Trust of America’s portfolio over the period. Commercial paper decreased from 80.5% of holdings to 73.8%, while federal agency discount notes went from 18.1% to 15.9%. At the same time, we joined other investors in adding to our holdings of U.S. Treasuries and increased them to 9.9% by the end of March, compared with 0.7% six months earlier.

Despite declines in short-term interest rates and lower yields, the money market funds

continue to offer good income and price stability in a period of volatile equity and fixed-income markets. As always, we will continue to rigorously research and monitor appropriate credit issuers in an effort to find the best possible investments for the funds.

The funds’ objective

In challenging economic times such as these, we are reminded that money market funds can have a steadying influence on broader portfolios. Using a combination of independent credit research and a conservative approach to investing, our money market funds aim to provide you with both a reasonable return and relative stability.

On a final note, we extend a warm welcome to all our new shareholders. Whether you’re using these funds as a temporary holding place for cash or as a way to earn income, we hope our money market funds — as one part of a diversified portfolio — assist you in reaching your long-term goals.

Cordially,

1. Organization and significant accounting policies

Organization – The Cash Management Trust of America (the "fund") is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide income on cash reserves, while preserving capital and maintaining liquidity, through investments in high-quality short-term money market instruments.

The fund offers 14 share classes consisting of four retail share classes, five 529 college savings plan share classes and five retirement plan share classes. The 529 college savings plan share classes (529-A, 529-B, 529-C, 529-E and 529-F) can be used to save for college education. The five retirement plan share classes (R-1, R-2, R-3, R-4 and R-5) are sold without any sales charges and do not carry any conversion rights. The fund’s share classes are described below:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Class A and 529-A	None	None	None
Class B and 529-B	None	Declines from 5% to 0% for redemptions within six years of purchase	Class B and 529-B convert to Class 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 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Class F and 529-F	None	None	None
Class R-1, R-2, R-3, R-4 and R-5	None	None	None

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 class.

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 following is a summary of the significant accounting policies followed by the fund:

Net asset value – The fund values its shares in accordance with Securities and Exchange Commission ("SEC") rules, using the penny-rounding method, which permits the fund to maintain a constant net asset value of $1.00 per share.

Security valuation – Fixed-income securities, including short-term securities purchased with more than 60 days left to maturity, are valued at prices obtained from an independent pricing service when such prices are available. However, where the investment adviser deems it appropriate, such securities will be valued at the mean quoted bid and asked prices (or bid prices, if asked prices are not available) or at prices for securities of comparable maturity, quality and type. Short-term securities purchased within 60 days to maturity are valued at amortized cost, which approximates market 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 or less remaining to maturity. The ability of the issuers of the debt securities held by the fund to meet their obligations may be affected by economic developments in a specific industry, state or region.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the investment adviser are fair valued as determined in good faith under procedures adopted by authority of the fund's board of trustees. Various factors may be reviewed in order to make a good faith determination of a security’s fair value. These factors include, but are not limited to, 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.

Security transactions and related investment income – Security transactions are recorded by the fund as of the date the trades are executed with brokers. 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) are allocated daily among the various share classes based on the relative value of their settled shares. 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 to shareholders – Dividends paid to shareholders are declared daily after the determination of the fund’s net investment income and are paid to shareholders monthly.

2. Federal income taxation and distributions

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 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 March 31, 2008, 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 2003 and by state tax authorities for tax years before 2002.

Distributions – Distributions paid to shareholders are based on net investment income determined on a tax basis, which may differ from net investment income for financial reporting purposes.

3. Fees and transactions with related parties

Capital Research and Management Company ("CRMC"), the fund’s investment adviser, is the parent company of American Funds Service Company SM ("AFS"), the fund’s transfer agent, and American Funds Distributors, SM Inc. ("AFD"), the principal underwriter of the fund’s shares.

Investment advisory services - The Investment Advisory and Service Agreement with CRMC provides for monthly fees accrued daily. These fees are based on a declining series of annual rates beginning with 0.320% on the first $1 billion of daily net assets and decreasing to 0.270% on such assets in excess of $2 billion. CRMC is currently waiving 10% of investment advisory services fees. During the six months ended March 31, 2008, total investment advisory services fees waived by CRMC were $2,293,000. As a result, the fee shown on the accompanying financial statements of $22,931,000, which was equivalent to an annualized rate of 0.274%, was reduced to $20,638,000, or 0.247% of average daily net assets.

The Investment Advisory and Service Agreement also provides that CRMC will reimburse the fund’s Class A shares to the extent that annual operating expenses exceed 25% of gross income. Expenses related to interest, taxes, brokerage commissions and extraordinary items are not subject to these limitations. During the six months ended March 31, 2008, no such reimbursement was required.

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 adopted plans of distribution for all share classes, except Class R-5. 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 0.15% 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 may use a portion (0.15% for Class A, B, 529-A and 529-B shares and 0.25% for all other share classes) 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.

Share class	Currently approved limits	Plan limits
Class A	0.15%	0.15%
Class 529-A	0.15	0.50
Class B and 529-B	0.90	0.90
Class C, 529-C and R-1	1.00	1.00
Class R-2	0.75	1.00
Class 529-E and R-3	0.50	0.75
Class F, 529-F and R-4	0.25	0.50

Transfer agent services – The fund has a transfer agent agreement with AFS for Class A and B. Under this agreement, these share classes compensate AFS for transfer agent services including shareholder recordkeeping, communications and transaction processing. AFS is also compensated for certain transfer agent services provided to all other share classes from the administrative services fees paid to CRMC described below.

Administrative services – The fund has an administrative services agreement with CRMC to provide transfer agent and other related shareholder services for all share classes other than Class A and B. Each relevant share class pays CRMC annual fees up to 0.15% (0.10% for Class R-5) based on its respective average daily net assets. Each relevant share class also pays AFS additional amounts for certain transfer agent services. CRMC and AFS may use these fees to compensate third parties for performing these services. CRMC has agreed to pay AFS on the fund's behalf for a portion of the transfer agent services fees for some of the retirement plan share classes. For the six months ended March 31, 2008, the total administrative services fees paid by CRMC were $124,000 for Class R-2. Administrative services fees are presented gross of any payments made by CRMC. Each 529 share class is subject to an additional annual administrative services fee of 0.10% of its respective average daily net assets; this fee is payable to the Commonwealth of Virginia for the maintenance of the 529 college savings plan. Although these amounts are included with administrative services fees on the accompanying financial statements, the Commonwealth of Virginia is not considered a related party.

Expenses under the agreements described above for the six months ended March 31, 2008, were as follows (dollars in thousands):

Trustees’ deferred compensation – Since the adoption of the deferred compensation plan in 1993, trustees who are unaffiliated with CRMC may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the fund, are treated as if invested in shares of the fund. These amounts represent general, unsecured liabilities of the fund and vary according to the total return of the fund. Trustees’ compensation on the accompanying financial statements includes the current fees (either paid in cash or deferred) and the net increase or decrease in the value of the deferred amounts.

Affiliated officers and trustees – Officers and certain trustees of the fund are or may be considered to be affiliated with CRMC, AFS and AFD. No affiliated officers or trustees received any compensation directly from the fund.

The fund’s investment adviser waived 10% of its management fees beginning October 1, 2005. The investment adviser also has reimbursed certain expenses for some share classes. Fund results shown reflect the waiver and/or reimbursement, without which they would have been lower. Please see the Financial Highlights table on pages 22 to 27 for details.

Expense example

unaudited

As a shareholder of the fund, you incur certain ongoing costs, including management fees; distribution and service (12b-1) fees; and other expenses. Certain share classes also incur transaction costs such as contingent deferred sales charges (loads) on redemptions. 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 period (October 1, 2007, through March 31, 2008).

Actual expenses:

The first line of each share class in the table on page 31 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 page 31 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 and 529-F 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 on the previous page. In addition, your ending account value would also be lower by the amount of these fees.

Please 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.

Approval of Investment Advisory and Service Agreement

The fund’s board has approved the fund’s Investment Advisory and Service Agreement (the “agreement”) with Capital Research and Management Company (“CRMC”) for an additional one-year term through May 31, 2009. The board approved the agreement following the recommendation of the fund’s Contracts Committee (the “committee”), which is composed of all of the fund’s independent board members. The board and the committee determined that the fund’s advisory fee structure was fair and reasonable in relation to the services provided and that approving the agreement was in the best interests of the fund and its shareholders.

In reaching this decision, the board and the committee took into account information furnished to them throughout the year, as well as information prepared specifically in connection with their review of the agreement, and were advised by their independent counsel. They considered the factors discussed below, among others, but did not identify any single issue or particular piece of information that, in isolation, was the controlling factor.

1. Nature, extent and quality of services

The board and the committee considered the depth and quality of CRMC’s investment management process, including its global research capabilities; the experience, capability and integrity of its senior management and other personnel; the low turnover rates of its key personnel; the overall financial strength and stability of its organization; and the ongoing evolution of CRMC’s organizational structure designed to maintain and strengthen these qualities. The board and the committee also considered the nature, extent and quality of administrative, compliance and shareholder services provided by CRMC to the fund under the agreement and other agreements as well as the benefits to fund shareholders from investing in a fund that is part of a large family of funds. The board and the committee concluded that the nature, extent and quality of the services provided by CRMC have benefited and should continue to benefit the fund and its shareholders.

2. Investment results

The board and the committee considered the investment results of the fund in light of its objectives of providing shareholders with income on their cash reserves while preserving capital and maintaining liquidity. They compared the fund’s total returns with those of other relevant funds (including the other funds that are the basis of the Lipper index for the category in which the fund is included) and market data such as relevant market indices. This report, including the letter to shareholders and related disclosures, contains certain information about the fund’s investment results. The board and the committee concluded that the fund’s short- and long-term results have been satisfactory and that CRMC’s record in managing the fund indicated that its continued management should benefit the fund and its shareholders.

3. Advisory fees and total expenses

The board and the committee compared the advisory fees and total expense levels of the fund to those of other relevant funds. They observed that the fund’s advisory fees and expenses remain significantly below those of most other relevant funds. The board and the committee also noted the breakpoint discounts in the fund’s advisory fee structure that reduce the level of fees charged by CRMC to the fund as fund assets increase and the 10% advisory fee waiver in effect since October 2005. In addition, they reviewed information regarding the advisory fees paid by institutional clients of an affiliate of CRMC with investment mandates similar to those of the fund. They noted that, although the fees paid by those clients generally were lower than those paid by the fund, the differences appropriately reflected the significant investment, operational and regulatory differences between advising mutual funds and institutional clients. The board and the committee concluded that the fund’s cost structure was fair and reasonable in relation to the services provided, and that the shareholders receive reasonable value in return for the advisory fees and other amounts paid to CRMC by the fund.

4. Ancillary benefits

The board and the committee considered a variety of other benefits received by CRMC and its affiliates as a result of CRMC’s relationship with the fund and the other American Funds, including fees for administrative services provided to certain share classes; fees paid to CRMC’s affiliated transfer agent; sales charges and distribution fees received and retained by the fund’s principal underwriter, an affiliate of CRMC; and possible ancillary benefits to CRMC’s institutional management affiliates. The board and the committee reviewed CRMC’s portfolio trading practices, noting that while CRMC receives the benefit of research provided by broker-dealers executing portfolio transactions on behalf of the fund, it does not obtain third-party research or other services in return for allocating brokerage to such broker-dealers. The board and the committee took these ancillary benefits into account in evaluating the reasonableness of the advisory fees and other amounts paid to CRMC by the fund.

5. Adviser financial information

The board and the committee reviewed information regarding CRMC’s costs of providing services to the American Funds, including personnel, systems and resources of investment, compliance, trading, accounting and other administrative operations. They considered CRMC’s costs and willingness to invest in technology, infrastructure and staff to maintain and expand services and capabilities, respond to industry and regulatory developments and attract and retain qualified personnel. They noted information previously received regarding the compensation structure for CRMC’s investment professionals. The board and the committee also compared CRMC’s profitability to the reported results of several large, publicly held investment management companies. The board and the committee noted the competitiveness and cyclicality of both the mutual fund industry and the capital markets, and the importance in that environment of CRMC’s long-term profitability for maintaining its independence, company culture and management continuity. They further considered the breakpoint discounts in the fund’s advisory fee structure and the impact of CRMC’s current 10% advisory fee waiver, reflecting benefits that may accrue from growth in assets. The board and the committee concluded that the fund’s advisory fee structure reflected a reasonable sharing of benefits between CRMC and the fund’s shareholders.

1. Organization and significant accounting policies

Organization – The U.S. Treasury Money Fund of America (the "fund") is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide income on cash reserves, while preserving capital and maintaining liquidity, through investments in U.S. Treasury securities.

The fund offers six share classes consisting of one retail share class (Class A) and five retirement plan share classes (R-1, R-2, R-3, R-4 and R-5). All share classes are sold without any sales charges and do not carry any conversion rights.

Dividends to shareholders –Dividends paid to shareholders are declared daily after the determination of the fund’s net investment income and are paid to shareholders monthly.

2. Federal income taxation and distributions

The fund is not subject to examination by U.S. federal tax authorities for tax years before 2003 and by state tax authorities for tax years before 2002.

The components of distributable earnings on a tax basis are reported as of the fund’s most recent year-end. As of September 30, 2007, the fund had tax basis undistributed ordinary income of $190,000.

As of March 31, 2008, the tax basis unrealized appreciation (depreciation) and cost of investment securities were as follows:

(dollars in thousands)
Gross unrealized appreciation on investment securities	$	1,230
Gross unrealized depreciation on investment securities		(123	)
Net unrealized appreciation on investment securities		1,107
Cost of investment securities		1,373,730

Distributions paid or accrued to shareholders from ordinary income were as follows (dollars in thousands):

Share class	Six months ended March 31, 2008		Year ended September 30, 2007
Class A	$	11,667	$	24,200
Class R-1		24		73
Class R-2		440		1,306
Class R-3		494		1,192
Class R-4		345		419
Class R-5		266		574
Total	$	13,236	$	27,764

3. Fees and transactions with related parties

Investment advisory services - The Investment Advisory and Service Agreement with CRMC provides for monthly fees accrued daily. These fees are based on an annual rate of 0.300% on the first $800 million of daily net assets and 0.285% on such assets in excess of $800 million. CRMC is currently waiving 10% of investment advisory services fees. During the six months ended March 31, 2008, total investment advisory services fees waived by CRMC were $148,000. As a result, the fee shown on the accompanying financial statements of $1,479,000, which was equivalent to an annualized rate of 0.297%, was reduced to $1,331,000, or 0.267% of average daily net assets.

Distribution services – The fund has adopted plans of distribution for all share classes, except Class R-5. 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 0.15% 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 may use a portion (0.15% for Class A and 0.25% for all other share classes) 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.

Share class	Currently approved limits	Plan limits
Class A	0.15%	0.15%
Class R-1	1.00	1.00
Class R-2	0.75	1.00
Class R-3	0.50	0.75
Class R-4	0.25	0.50

Transfer agent services – The fund has a transfer agent agreement with AFS for Class A. Under this agreement, this share class compensates AFS for transfer agent services including shareholder recordkeeping, communications and transaction processing. AFS is also compensated for certain transfer agent services provided to all other share classes from the administrative services fees paid to CRMC described on the following page.

Expenses under the agreements described above for the six months ended March 31, 2008, were as follows (dollars in thousands):

Share class	Distribution services	Transfer agent services	Administrative services
Share class	Distribution services	Transfer agent services	CRMC administrative services	Transfer agent services

Expense example

unaudited

As a shareholder of the fund, you incur certain 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 period (October 1, 2007, through March 31, 2008).

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 (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. 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 also be lower by the amount of these fees.

Please note that the expenses shown in the table are meant to highlight your ongoing costs. 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.

1. Organization and significant accounting policies

Organization – The Tax-Exempt Money Fund of America (the "fund") is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide income free from federal taxes, while preserving capital and maintaining liquidity, by investing primarily in securities exempt from regular federal income tax.

The fund offers two share classes consisting of one retail share class (Class A) and one retirement plan share class (R-5). Each share class is sold without any sales charges and does not carry any conversion rights.

Class allocations – Income, fees and expenses (other than class-specific fees and expenses) are allocated daily among the two share classes based on the relative value of their settled shares. Unrealized gains and losses are allocated daily among the two 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 to shareholders – Dividends paid to shareholders are declared daily after the determination of the fund’s net investment income and are paid to shareholders monthly.

2. Federal income taxation and distributions

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 income each year. The fund is not subject to income taxes to the extent taxable income is distributed. Generally, income earned by the fund is exempt from federal income taxes.

The fund is not subject to examination by U.S. federal tax authorities for tax years before 2003 and by state tax authorities for tax years before 2002.

*The short-term loss carryforwards will be used to offset any capital gains realized by the fund in the current year or in subsequent years through the expiration dates. The fund will not make distributions from short-term gains while short-term loss carryforwards remain.

As of March 31, 2008, the tax basis unrealized appreciation (depreciation) and cost of investment securities were as follows:

3. Fees and transactions with related parties

Investment advisory services - The Investment Advisory and Service Agreement with CRMC provides for monthly fees accrued daily. These fees are based on a declining series of annual rates beginning with 0.390% on the first $200 million of daily net assets and decreasing to 0.290% on such assets in excess of $1.2 billion. CRMC is currently waiving 10% of investment advisory services fees. During the six months ended March 31, 2008, total investment advisory services fees waived by CRMC were $140,000. As a result, the fee shown on the accompanying financial statements of $1,399,000, which was equivalent to an annualized rate of 0.367%, was reduced to $1,259,000, or 0.330% of average daily net assets.

Distribution services – The fund has adopted a plan of distribution for Class A shares. Under the plan, 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 plan provides for payments, based on an annualized percentage of average daily net assets, of up to 0.15%. This class may use a portion 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 for providing certain shareholder services.

Transfer agent services – The fund has a transfer agent agreement with AFS for Class A. Under this agreement, this share class compensates AFS for transfer agent services including shareholder recordkeeping, communications and transaction processing. AFS is also compensated for certain transfer agent services provided to Class R-5 from the administrative services fees paid to CRMC described below.

Administrative services – The fund has an administrative services agreement with CRMC to provide transfer agent and other related shareholder services for Class R-5. This share class also pays AFS additional amounts for certain transfer agent services. CRMC and AFS may use these fees to compensate third parties for performing these services.
