Fellow shareholders:

The six-month period ended March 31, 2006, was marked by a combination of strong economic growth, rising short-term interest rates and relatively moderate inflation. This environment helped The Cash Management Trust of America, The U.S. Treasury Money Fund of America and The Tax-Exempt Money Fund of America provide solid returns for the period. All three funds maintained a constant net asset value of $1.00.

The funds’ results

The Cash Management Trust of America produced an income return of 1.86% (3.72% annualized), with dividends reinvested, for the first half of the fund’s fiscal year. The fund’s annualized seven-day yield as of March 31, 2006, was 4.09%.

The U.S. Treasury Money Fund of America generated a six-month income return of 1.64% (3.28% annualized), including reinvested dividends. 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 yield for the week ended March 31, 2006, was 3.78%.

The Tax-Exempt Money Fund of America provided a federally tax-free income return of 1.23% (2.46% annualized), with dividends reinvested, for the six-month period ended March 31, 2006. The income return is equivalent to a taxable return of 1.89% (3.78% annualized) for investors in the 35.0% federal tax bracket. A portion of this return may also be exempt from some state and local taxes. The fund’s annualized seven-day yield at the end of the period was 2.60%, and its taxable equivalent annualized seven-day yield was 4.00%.

The Fed and the economy

The U.S. economy continued to grow steadily during the first half of the funds’ fiscal year. In fact, over the past three months ended March 31, the U.S. economy grew at its fastest pace in more than two and a half years, according to the U.S. Department of Commerce. Growth was widespread and appeared to be unhindered by higher energy prices and rising interest rates. Core inflation, a critical measure of inflation used by the Federal Reserve that excludes volatile food and energy prices, increased 2.1% during the year ended March 31. Because of the rapid increase in energy, the overall rate of inflation increased by 3.4% over the same period.

[Begin Sidebar]

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

The Cash Management Trust of America	+4.09%
(reflecting a fee waiver, +4.06% without the waiver)
The U.S. Treasury Money Fund of America	+3.78%
(reflecting a fee waiver, +3.75% without the waiver)
The Tax-Exempt Money Fund of America	+2.60%
(reflecting a fee waiver, +2.56% without the waiver)
The Tax-Exempt Money Fund of America (taxable equivalent yield)2	+4.00%
(reflecting a fee waiver, +3.94% without the waiver)

The seven-day SEC yields more accurately reflect the funds’ current earnings than do their 30-day yields or total returns.

For The U.S. Treasury Money Fund of America and The Tax-Exempt Money Fund of America, the investment adviser waived 5% of its management fees from September 1, 2004, through March 31, 2005, and increased the waiver to 10% on April 1, 2005. For The Cash Management Trust of America, the investment adviser waived 10% of its management fees beginning October 1, 2005. Fund results shown reflect the waiver, without which they would have been lower. Please see the Financial Highlights tables on pages 22, 44 and 64 for details.

¹Equivalent to Securities and Exchange Commission (SEC) yields. Represents the seven-day month-end averages.

²Represents the fund’s taxable equivalent yield calculated at the maximum effective 35.0% federal tax rate.

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.

[End Sidebar]

The funds’ solid results for the six-month period were greatly influenced by the ongoing rate hikes of the Federal Reserve. (The chart on the previous page demonstrates the interplay between the federal funds rate and the funds’ yields.)

Since June 2004, the Fed has steadily raised its target lending rate in an effort to control economic growth and curb inflation. Altogether, there have been 15 quarter-point increases since June 2004, bringing the federal funds rate (the overnight lending rate among banks) to 4.75% by the close of this period. (The Fed raised the federal funds rate an additional quarter point on May 10.)

While many expect the Fed to raise rates further, the number of expected hikes is much debated. However, the outlook for continued economic growth and concerns about future gains in inflation are indicators that the Fed may continue to raise rates in the near term.

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 CollegeAmerica® savings plan share classes and five retirement plan share classes. The CollegeAmerica savings plan share classes (529-A, 529-B, 529-C, 529-E and 529-F) can be utilized 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 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.

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. As of March 31, 2006, there were no material differences between book and tax reporting. The fiscal year in which amounts are distributed may differ from the year in which the net investment income is recorded by the fund for financial reporting purposes. As of March 31, 2006, the cost of investment securities for federal income tax purposes was $9,561,693,000.

As of March 31, 2006, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed net investment income	$ 841
Short-term loss carryforward (expiring 2013)	(9)
Gross unrealized appreciation on investment securities	433
Gross unrealized depreciation on investment securities	(75)
Net unrealized appreciation on investment securities	358

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

Share class	Six months ended March 31, 2006		Year ended September 30, 2005
Class A	$	144,853	$	166,009

Total	$	167,751	$	185,586

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 ("AFS"), the fund’s transfer agent, and American Funds Distributors, Inc. ("AFD"), the principal underwriter of the fund’s shares.

Investment advisory services - The Investment Advisory and Service Agreementwith 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, 2006, total investment advisory services fees waived by CRMC were $1,286,000. As a result, the fee shown on the accompanying financial statements of $12,860,000, which was equivalent to an annualized rate of 0.278%, was reduced to $11,574,000, or 0.250% 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, 2006, 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, 2006, the total administrative services fees paid by CRMC were $2,000, $665,000 and $57,000 for Class R-1, R-2 and R-3, respectively. 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 CollegeAmerica 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, 2006, were as follows (dollars in thousands):

Share class	Distribution services	Transfer agent services	Administrative services
			CRMC administrative services	Transfer agent services	Commonwealth of Virginia administrative services
Class A	$3,004	$5,891	Not applicable	Not applicable	Not applicable

Class R-5	Not applicable		50	9	Not applicable
Total	$7,030	$5,966	$942	$1,684	$86

Deferred trustees’ 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 page 22 for details.

*These shares are sold without any initial or contingent deferred sales charge.

^†Results shown do not reflect the $10 initial account setup fee and an annual $10 account maintenance fee.

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, 2005, through March 31, 2006).

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. There are some account fees that are charged to certain types of accounts, such as Individual Retirement Accounts and CollegeAmerica 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 Class 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 above. In addition, your ending account value would also be lower by the amount of these fees.

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. There are some account fees that are charged to certain types of accounts, such as Individual Retirement Accounts and CollegeAmerica 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 Class 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, 2007. 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 information, material facts and conclusions that formed the basis for the committee’s recommendation and the board’s subsequent approval are described below.

1. Information reviewed

Materials reviewed — During the course of each year, board members review a wide variety of materials relating to the services provided by CRMC, including reports on the fund’s investment results, portfolio composition, portfolio trading practices, shareholder services, and other information relating to the nature, extent and quality of services provided by CRMC to the fund. In addition, the committee requests and reviews supplementary information that includes extensive materials regarding the fund’s investment results, advisory fee and expense comparisons, financial and profitability information regarding CRMC, descriptions of various functions such as compliance monitoring and portfolio trading practices, and information about the personnel providing investment management and administrative services to the fund.

Review process — The committee received assistance and advice regarding legal and industry standards from independent counsel to the board. The committee discussed the approval of the agreement with CRMC representatives and in a private session with counsel at which no representatives of CRMC were present. In deciding to recommend approval of the agreement, the committee did not identify any single or particular piece of information that, in isolation, was the controlling factor. This summary describes the most important, but not all, of the factors considered by the board and the committee.

2. Nature, extent and quality of services

CRMC, its personnel and its resources— 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 ability of its organizational structure to address the recent growth in assets under management. The board and the committee also considered that CRMC made available to its investment professionals a variety of resources and systems relating to investment management, compliance, trading, investment results and portfolio accounting. They considered CRMC’s commitment to investing in information technology supporting investment management and compliance. They further considered CRMC’s continuing need to attract and retain qualified personnel and to maintain and enhance its resources and systems. The board and the committee also considered the benefits to fund shareholders from investing in a fund that is part of a large family of funds offering a variety of investment objectives.

Other services— The board and the committee considered the investment adviser’s policies, procedures and systems designed to comply with applicable laws and regulations and its commitment to compliance; its efforts to keep the board members informed; and its attention to matters that may involve potential conflicts of interest with the fund. The board and the committee also considered the nature, extent, quality and cost of administrative, distribution and shareholder services provided by the investment adviser to the fund under the agreement and other agreements, including the information technology, legal, and fund accounting and treasury functions.

3. Investment results

The board and the committee considered the investment results of the fund in light of its objective of providing shareholders with income on their cash reserves while preserving capital and maintaining liquidity. They compared the fund’s total returns with the total returns of the Lipper Money Market Funds Index (the Lipper category that includes the fund) and the average of the funds included in the Lipper Index each year. The board and the committee noted that for the one-, three-, five- and 10-year periods ended December 31, 2005, the fund’s investment results equaled or exceeded all of these measures.

4. Advisory fees and total expenses

The board and the committee reviewed the advisory fees and total expenses of the fund (each as a percentage of average net assets) and compared such amounts with the median fee and expense levels of all other funds in the Lipper Money Market Funds Index. The board and the committee observed that the fund’s advisory fee was below the median of the funds in that comparison group for the fiscal year ended December 31, 2005, and had been below the median of the other funds included in the Lipper Index for the entire 10-year period ended on that date. They also observed that the fund’s total expenses had been below the median of the funds in that comparison group for the fiscal year ended December 31, 2005, and most of the 10-year period ended on that date. The board and the committee also noted the 10% advisory fee waiver that CRMC put into effect on October 1, 2005.

The board and the committee also reviewed information regarding the advisory fees paid by institutional clients of an affiliate of CRMC with similar investment mandates. They noted that, although the fees paid by those clients generally were lower than those paid by the American Funds, the differences appropriately reflected the significant investment, operational and regulatory differences between advising mutual funds and institutional clients.

5. Adviser financial information

The board and the committee reviewed information regarding CRMC’s costs of providing services to the American Funds, as well as the resulting level of profits to CRMC, comparing those to the reported results of several large, publicly held investment management companies. The board and the committee also received information during the past year regarding the structure and manner in which CRMC’s investment professionals were compensated and CRMC’s view of the relationship of such compensation to the attraction and retention of quality personnel. The board and the committee considered CRMC’s willingness to invest in technology, infrastructure and staff to reinforce and offer new services and to accommodate changing regulatory requirements. They further considered that breakpoint discounts in the fund’s advisory fee structure reduce the level of fees charged by CRMC to the fund as fund assets increase. They also considered the impact of the current 10% advisory fee waiver.

6. 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 the investment adviser’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.

7. Conclusions

Based on their review, including their consideration of each of the factors referred to above, the board and the committee concluded that the agreement is fair and reasonable to the fund and its shareholders, that the fund’s shareholders receive reasonable value in return for the advisory fees and other amounts paid to CRMC by the fund, that each of the factors discussed above supported approval of the agreement, and that approval of the agreement was in the best interests of the fund and its 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 maturing in one year or less.

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.

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. Securities and other assets for which representative market quotations are not readily available are fair valued as determined in good faith under procedures adopted by authority of the fund's board of trustees.

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 recognizedon an accrual basis. Market discounts, premiums and original issue discountson 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.

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. As of March 31, 2006, there were no material differences between book and tax reporting. The fiscal year in which amounts are distributed may differ from the year in which the net investment income is recorded by the fund for financial reporting purposes. As of March 31, 2006, the cost of investment securities for federal income tax purposes was $532,095,000.

As of March 31, 2006, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed net investment income	$	120
Gross unrealized appreciation on investment securities		101
Gross unrealized depreciation on investment securities		-
Net unrealized appreciation on investment securities		101

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

Share class	Six months ended March 31, 2006		Year ended September 30, 2005
Class A	$	7,588	$	9,126
Class R-1		16		13
Class R-2		333		254
Class R-3		327		265
Class R-4		70		62
Class R-5		134		136
Total	$	8,468	$	9,856

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 ("AFS"), the fund’s transfer agent, and American Funds Distributors, 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 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, 2006, total investment advisory services fees waived by CRMC were $80,000. As a result, the fee shown on the accompanying financial statements of $796,000, which was equivalent to an annualized rate of 0.300%, was reduced to $716,000, or 0.270% of average daily net assets.

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 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 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. Each relevant shareclass 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, 2006, the total administrative services fees paid by CRMC were $107 and $31,000 for Class R-1 and R-2, respectively.Administrative services fees are presented gross of any payments made by CRMC.

Expenses under the agreements described on the previous page for the six months ended March 31, 2006, were as follows (dollars in thousands):

Share class	Distribution services	Transfer agent services	Administrative services
			CRMC administrative services	Transfer agent services
Class A	$223	$340	Not applicable	Not applicable
Class R-1	7	Included in administrative services	$1	$ -*
Class R-2	104		21	68
Class R-3	59		17	16
Class R-4	6		4	1
Class R-5	Not applicable		4	-*
Total	$399	$340	$47	$85

* Amount less than one thousand.

Deferred trustees’ 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.

(1) Based on operations for the periods shown (unless otherwise noted) and, accordingly, may not be representative of a full year.

(2) Based on average shares outstanding.

(3) The ratios in this column reflect the impact, if any, of certain reimbursements/waivers from CRMC. During some of the periods shown CRMC, reduced fees for investment advisory services for all share classes. During the start-up period for the retirement plan share classes (excpt Class R-5), CRMC agreed to pay a portion of the fees related to transfer agent services. In addition, during some of the periods shown, due to lower short-term interest rates, CRMC agreed to pay a portion of the class-specific fees and expenses.

(4) Unaudited.

(5) Annualized.

Expense example                       &# 160;      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, 2005, through March 31, 2006).

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. 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.

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. 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 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. 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.

* Expenses are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by the number of days in the period (182), and divided by 365 (to reflect the one-half year period).

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, through investments in high-quality municipal securities with effective maturities of one year or less.

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.

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 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 recognizedon 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 two share classes based on the relative value of their settled shares. Realized and 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 and distributions 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 such distributions are made. Generally, income earned by the fund is exempt from federal income taxes.

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. As of March 31, 2006, there were no material differences between book and tax reporting. The fiscal year in which amounts are distributed may differ from the year in which the net investment income is recorded by the fund for financial reporting purposes. As of March 31, 2006, the cost of investment securities, for federal income tax purposes was $431,826,000.

As of March 31, 2006, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed net investment income	$131
Short-term loss carryforwards (expiring 2006-2011)		(94	)
Gross unrealized appreciation on investment securities		1
Gross unrealized depreciation on investment securities		(75	)
Net unrealized depreciation on investment securities		(74	)

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

Share class		Six months ended March 31, 2006		Year ended September 30, 2005
Class A	$	4,925	$	6,341
Class R-5		379		339
Total	$	5,304	$	6,680

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 ("AFS"), the fund’s transfer agent, and American Funds Distributors, Inc. ("AFD"), the principal underwriter of the fund’s shares

Investment advisory services - The Investment Advisory and Service Agreement with CRMC providesfor 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. During the six months ended March 31, 2006, total investment advisory services fees waived by CRMC were $82,000. As a result, the fee shown on the accompanying financial statements of $821,000, which was equivalent to an annualized rate of 0.379%, was reduced to $739,000, or 0.341% of average daily net assets.

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 Class A 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, 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 to provide 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 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

Deferred trustees’ 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.

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, 2005, through March 31, 2006).

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. 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.

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. 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 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. 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.

	Beginning account value 10/1/2005		Ending account value 3/31/2006		Expenses paid during period*		Annualized expense ratio
Class A -- actual return	$	1,000.00	$	1,012.30	$	2.46		.49	%
Class A -- assumed 5% return		1,000.00		1,022.49		2.47		.49

Class R-5 -- assumed 5% return		1,000.00		1,022.29		2.67		.53

^* Expenses are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by the number of days in the period (182), and divided by 365 (to reflect the one-half year period).

Most American Funds offer several share classes, each with its own sales charge and expense structure, allowing you to choose the one that best meets your financial needs. The three American Funds money market funds each offer Class A shares at no sales charge.

The Cash Management Trust of America (CMTA) is the only American Funds money market fund that offers Class B, Class C, Class F and Class 529 shares. CMTA Class B, C and F shares may be acquired only by exchanging from other American Funds within the same share class (i.e., they may not be purchased directly) and do not offer check-writing privileges. American Funds Class B, C and F shares are subject to additional annual expenses and fees, including, in the case of Class B and C shares, higher 12b-1 fees and contingent deferred sales charges if Class B shares are redeemed within six years of purchase and Class C shares are redeemed within one year of purchase. Class B, C and F shares are not available to certain employer-sponsored retirement plans. See the CMTA prospectus for further details.

Investors should carefully consider the investment objectives, risks, charges and expenses of the American Funds. This and other important information is contained in the funds’ prospectus, which can be obtained from your financial adviser and should be read carefully before investing. You may also call American Funds Service Company (AFS) at 800/421-0180 or visit the American Funds website at americanfunds.com.

“American Funds Proxy Voting Guidelines” — which describes how we vote proxies relating to portfolio securities — is available free of charge on the U.S. Securities and Exchange Commission (SEC) website at sec.gov, on the American Funds website or upon request by calling AFS. The funds file their proxy voting records with the SEC for the 12 months ended June 30 by August 31. The reports also are available on the SEC and American Funds websites.

The Cash Management Trust of America, The U.S. Treasury Money Fund of America and The Tax-Exempt Money Fund of America file a complete list of their portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. This filing is available free of charge on the SEC website. You may also review or, for a fee, copy this filing at the SEC’s Public Reference Room in Washington, D.C. (800/SEC-0330). Additionally, the list of portfolio holdings also is available by calling AFS.

This report is for the information of shareholders of The Cash Management Trust of America, The U.S. Treasury Money Fund of America and The Tax-Exempt Money Fund of America, but it may also be used as sales literature when preceded or accompanied by the current prospectus, which gives details about charges, expenses, investment objectives and operating policies of the funds. If used as sales material after June 30, 2006, this report must be accompanied by an American Funds statistical update for the most recently completed calendar quarter.

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, as amended, and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are attached as exhibits hereto.
