                             PRESIDENT'S MESSAGE

Dear Shareholder:

I am pleased to present the Semi-Annual Report to Shareholders for Automated
Cash Management Trust, a portfolio of Money Market Obligations Trust. This
report covers the first half of the fund's fiscal year, which is the six-month
period ended January 31, 1998. It begins with an investment review of the
short-term market from the fund's portfolio manager. Following the investment
review are the fund's portfolio of investments and financial statements.

Over the six-month reporting period, dividends paid to shareholders of the
fund's Institutional Service Shares and Cash II Shares each totaled $0.03 per
share. At the end of the reporting period, net assets totaled $2.2 billion.

In Automated Cash Management Trust, your ready cash is at work pursuing daily
income, along with a high level of liquidity and a stable net asset value of
$1.00 per share.* At the end of the reporting period, the fund's assets were
invested in commercial paper (30.4%), variable rate instruments (25.8%),
repurchase agreements (23.0%), short-term notes (10.1%), time deposits (6.1%),
and certificates of deposit (4.8%).

Thank you for participating in the daily earning power of this high-quality
money market mutual fund. As always, we welcome your questions, comments, or
suggestions.

Sincerely,

* Money market funds seek to maintain a stable net asset value of $1.00 per
share. There is no assurance that they will be able to do so. An investment
in the fund is not insured or guaranteed by the U.S. government.

                              INVESTMENT REVIEW

Automated Cash Management Trust invests in money market instruments maturing in
thirteen months or less. The average maturity of these securities, computed on a
dollarweighted basis, is restricted to 90 days or less. Portfolio securities
must be rated in the highest short-term rating category by one or more of the
nationally recognized statistical rating organizations or, if unrated, be of
comparable quality to securities having such ratings. Typical security types
include, but are not limited to: commercial paper, certificates of deposit, time
deposits, variable rate instruments, and repurchase agreements.

Growth during 1997 continued at an above-average pace, slowing only moderately
during the third quarter. Specifically, third quarter gross domestic product
("GDP") registered 3.1% while fourth quarter GDP climbed back up to 3.9%.
Despite the high growth, inflation remained subdued by all measures. The
consumer price index rose just 1.6% on an annualized basis for the six month
period ended January 31, 1998. For the same time period, the producer price
index actually declined 0.9%, due mostly to a decline in energy prices, while
the employment cost index grew at an annualized 3.7% pace during the second half
of 1997.

Thirty-day commercial paper started the reporting period at 5.53% on August 1,
1997, and then rose as high as 5.98% on December 29, 1997, reflecting year-end
technical pressures. Rates fell back off again in January 1998 with 30-day
commercial paper settling in at the 5.50% level.

The money market yield curve flattened throughout the reporting period.
One-month commercial paper rates declined one basis point while six-month rates
declined 14 basis points reflecting the concern in the market about the Asian
contagion and its overall effect on U.S. growth.

The target average maturity range for the fund remained 35-45 days throughout
the reporting period, reflecting neutral economic and monetary sentiment. In
structuring the fund, there was continued emphasis placed on positioning 30-35%
of the fund's assets in variable rate demand notes and accomplishing a modest
barbell structure.

During the six-month period ended January 31, 1998, the net assets of the fund
increased from $2.1 to $2.2 billion while the 7-day net yield increased from
5.13% to 5.18% for the Institutional Service Shares,* and from 4.96% to 5.01%
for Cash II Shares.* The effective average maturity of the fund on January 31,
1998, was 42 days.

* Performance quoted represents past performance and is not indicative of
future results. Yield will vary. Yields quoted for money market funds most
closely reflect the fund's current earnings.PORTFOLIO OF INVESTMENTS

                        NOTES TO FINANCIAL STATEMENTS

                      AUTOMATED CASH MANAGEMENT TRUST

                        JANUARY 31, 1998 (UNAUDITED)

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of six portfolios. The financial
statements included herein are only those of Automated Cash Management Trust
(the "Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held. The investment
objective of the Fund is stability of principal and current income consistent
with stability of principal.

The Fund offers two classes of shares: Institutional Service Shares and Cash
II Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value their portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System, or to have
segregated within the custodian bank's vault, all securities held as collateral
under repurchase agreement transactions. Additionally, procedures have been
established by the Fund to monitor, on a daily basis, the market value of each
repurchase agreement's collateral to ensure that the value of collateral at
least equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed by
the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less than
the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of their income. Accordingly, no provisions for federal tax
are necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon registration
under federal securities laws or in transactions exempt from such registration.
Many restricted securities may be resold in the secondary market in transactions
exempt from registration. In some cases, the restricted securities may be resold
without registration upon exercise of a demand feature. Such restricted
securities may be determined to be liquid under criteria established by the
Trustees. The Fund will not incur any registration costs upon such resales.
Restricted securities are valued at amortized cost in accordance with Rule 2a-7
under the Investment Company Act of 1940.

Additional information on each restricted security held at January 31, 1998 is
as follows:

                                              ACQUISITION    ACQUISITION
                   SECURITY DATE COST Liquid Asset Backed Securities Trust,
 5.614% 8/15/1996 $60,000,000 Liquid Asset Backed Securities Trust, 5.594%
 2/19/1997 23,281,931 Liquid Asset Backed Securities Trust, 5.876% 6/27/1997

 Triangle Funding Ltd., 5.594% 10/16/1997 5,000,000

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses, and revenues reported in
the financial statements. Actual results could differ from those estimated.

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares. At January 31, 1998, capital paid-in aggregated $2,203,800,340.
Transactions in shares were as follows:

for its services an annual investment advisory fee equal to 0.50% of the Fund's

portion of its fee. The Adviser can modify or terminate this voluntary waiver at
any time at its sole discretion.

ADMINISTRATIVE FEE

Federated Services Company ("FServ"), under the Administrative Services
Agreement, provides the Fund with administrative personnel and services. The fee
paid to FServ is based on the level of average aggregate daily net assets of all

DISTRIBUTION SERVICES FEE

The Fund has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1
under the Act. Under the terms of the Plan, the Fund will compensate Federated
Securities Corp. ("FSC"), the principal distributor, from the net assets of the
Fund to finance activities intended to result in the sale of the Fund's Cash II
Shares. The Plan provides that the Fund may incur distribution expenses up to
0.25% of the average daily net assets of Cash II Shares, annually, to compensate
FSC. FSC may voluntarily choose to waive any portion of its fee. FSC can modify

SHAREHOLDER SERVICES FEE

Under the terms of a Shareholder Services Agreement with Federated Shareholder

Mutual funds are not bank deposits or obligations, are not guaranteed by any
bank, and are not insured or guaranteed by the U.S. government, the Federal
Deposit Insurance Corporation, the Federal Reserve Board, or any other
government agency. Investment in mutual funds involves investment risk,
including possible loss of principal. Although money market funds seek to

PRESIDENT'S MESSAGE

Dear Shareholder:

I am pleased to present the Semi-Annual Report to Shareholders for Government
Obligations Fund, a portfolio of Money Market Obligations Trust. This report
covers the first half of the fund's fiscal year, which is the six-month period
ended January 31, 1998. It begins with an investment review of the short-term
government market from the fund's portfolio manager. Following the investment
review are the fund's portfolio of investments and financial statements.

Over the six-month reporting period, dividends paid to shareholders of the
fund's Institutional Shares and Institutional Service Shares each totaled $0.03
per share. At the end of the reporting period, net assets reached the $4.6
billion mark.

In Government Obligations Fund, your ready cash is at work pursuing daily
income, along with the additional advantages of daily liquidity and stability of
principal.* At the end of the reporting period, the fund's portfolio was
invested in repurchase agreements fully collateralized by U.S. government
securities (62.3%), and in short-term U.S. government obligations (39.4%).

Thank you for your confidence in the daily earning power of this high-quality
cash investment. As always, your questions and comments are welcome.

Sincerely,

J. Christopher Donahue
President
March 15, 1998

* Money market funds seek to maintain a stable net asset value of $1.00 per
share. There is no assurance that they will be able to do so. An investment
in the fund is not insured or guaranteed by the U.S. government.

INVESTMENT REVIEW

Government Obligations Fund, which is rated AAAm* by Standard & Poor's ("S&P")
and Aaa* by Moody's Investors Service, Inc. ("Moody's"), is invested in direct
U.S. Treasury and agency obligations and in repurchase agreements which have
these securities as collateral. The fund continued to emphasize issues of the
Federal National Mortgage Association, Student Loan Marketing Association,
Federal Farm Credit Bank System, Federal Home Loan Bank System, Federal Home
Loan Mortgage Corp., and, at times, maintained a small Treasury position for
liquidity purposes.

Over the six-month period ended January 31, 1998, the Federal Reserve Board (the
"Fed") stood pat in the face of economic growth that continued to exceed the
2.5% pace thought to be the non-inflationary potential. The federal funds target
remained at 5.5%, where it has been since the Fed tightened monetary policy in
March 1997. With gross domestic product ("GDP") growth at 3.1% over the third
quarter of 1997, expectation was built for the need for an additional tightening
from the Fed as added insurance against inflation. However, dramatic declines in
the Asian equity markets curtailed this expectation, and overseas developments
dominated the rest of the fourth quarter of 1997. Although GDP growth expanded
at close to 4% over this period, the Fed kept monetary policy unchanged, as
inflation at the wholesale and consumer level remained benign.

Movements in short-term Treasury securities--particularly Treasury bills--were
strongly influenced by technical factors over the reporting period. A reduction
in the overall size of Treasury bills due to improvement in the federal budget
deficit kept these securities well-bid and trading well below the federal funds
target. In addition, a periodic flight-to-quality to these securities from
investors seeking a safe haven from the turmoil overseas also drove their yields
lower. As a result, yields on short-term agency securities better reflected the
underlying economic and inflation fundamentals, and were the preferred
investment over the reporting period. The yield on the one-year agency discount
note, for example, began the reporting period at 5.65% in August, traded within
a fairly narrow range until early November, then climbed steadily to 5.85% by
early December. That peak came as the economy kept chugging along and the Asian
crisis subsided. The yield then dropped to 5.4% by early January 1998, as fears
grew that the as-yet-unknown impact of the financial troubles in Asia on the
domestic economy might be greater than previously thought. The yield then
rebounded slightly to 5.5% to end the reporting period, as growth continued
strong.

The fund was targeted in a 35-45 day average maturity range over the reporting
period, a neutral stance for the portfolio. Once an average maturity range is
established, the fund attempts to maximize performance through ongoing relative
value analysis. The fund's structure remained barbelled over the reporting
period, as a yield advantage continued to exist for repurchase agreements
relative to other short-term investments. The fund combined a position in
repurchase agreements collateralized by U.S. government mortgage-backed
securities with short-term agency floating rate notes to form the front end of
the barbell. We coupled this position with purchases of fixed-rate Treasury or
agency securities with longer maturities of between 6 and 13 months, although
agency securities remained the preferred investment. This portfolio structure
provided a competitive yield for the fund.

The risks to the Fed at this juncture appear to be balanced, with the threat of
higher inflation stemming from tight labor markets being potentially offset by
the as-yet-unknown impact of the Asian "flu." The Fed should be content to "wait
and see" until the effects on the domestic economy are better understood--which
should become more clear over the second quarter of 1998. We would expect to
maintain our current neutral positioning over this period. However, changing
economic and market developments are continuously monitored to best serve our
clients attracted to the short-term U.S.
government market.

* An AAAm rating is obtained after S&P evaluates a number of factors, including
credit quality, market price exposure and management. S&P monitors the portfolio
weekly for developments that could cause changes in the ratings. Money market
funds and bond funds rated Aaa by Moody's are judged to be of an investment
quality similar to Aaa-rated fixed income obligations, that is, they are judged
to be of the best quality. These ratings do not remove market risks and are
subject to change.

                        NOTES TO FINANCIAL STATEMENTS
                        GOVERNMENT OBLIGATIONS FUND
                        JANUARY 31, 1998 (UNAUDITED)

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of six portfolios. The financial
statements included herein are only those of Government Obligations Fund (the
"Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held. The investment
objective of the Fund is to provide current income consistent with stability of
principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System, or to have
segregated within the custodian bank's vault, all securities held as collateral
under repurchase agreement transactions. Additionally, procedures have been
established by the Fund to monitor, on a daily basis, the market value of each
repurchase agreement's collateral to ensure that the value of collateral at
least equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed by
the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less than
the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses, and revenues reported in
the financial statements. Actual results could differ from those estimated.

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares. At January 31, 1998, capital paid-in aggregated $4,641,866,483.
Transactions in shares were as follows:

                             PRESIDENT'S MESSAGE

Dear Shareholder:

I am pleased to present the Semi-Annual Report to Shareholders for Government
Obligations Tax-Managed Fund, a portfolio of Money Market Obligations Trust.
This report covers the first half of the fund's fiscal year, which is the
six-month period ended January 31, 1998. It begins with an investment review of
the short-term government market from the fund's portfolio manager. Following
the investment review are the fund's portfolio of investments and financial
statements.

Over the six-month reporting period, tax-free dividends paid to shareholders of
the fund's Institutional Shares and Institutional Service Shares each totaled
$0.03 per share. At the end of the reporting period, net assets reached $1.6
billion.

Government Obligations Tax-Managed Fund helps your cash pursue daily dividends,
a high level of liquidity, and a stable net asset value of $1.00 per share.* In
addition, the fund's portfolio of U.S. government securities is managed so that
dividends are exempt from state and local income taxes.**

Thank you for participating in the daily earning power of this high-quality,
tax-advantaged money market mutual fund. As always, we welcome your questions,
comments, or suggestions.

Sincerely,

J. Christopher Donahue President

                              INVESTMENT REVIEW

Government Obligations Tax-Managed Fund, which is rated AAAm* by Standard &
Poor's ("S&P") and Aaa* by Moody's Investors Service, Inc. ("Moody's"), invests
only in U.S. Treasury and U.S. government agency obligations. The fund invests
in issues of the Student Loan Marketing Association, the Federal Farm Credit
Bank System, the Federal Home Loan Bank System, and the Tennessee Valley
Authority. The fund maintains a small Treasury security position for liquidity
purposes. The fund does not invest in repurchase agreements, and is managed to
provide distributions which may be exempt from state and local taxes.

Over the six-month period ended January 31, 1998, the Federal Reserve Board (the
"Fed") made no changes in monetary policy, electing to maintain the federal
funds target rate at 5.50%. Another very favorable aspect of U.S. economic
performance was the improvement in the federal budget deficit picture. In fiscal
1997, the deficit dropped to its lowest level in more than two decades.
Projections show the budget essentially remaining in balance over the next
several years. As a result of the budget picture and the reality of less
issuance of Treasury securities, market technicals at the front-end of the yield
curve resulted in the yield on both the three-month and six-month Treasury bills
drifting lower during August and September. The yield on the three-month
Treasury bill began the reporting period at 5.27% and fell to 4.91% in late
September. The six-month Treasury bill followed a similar path, beginning the
reporting period at 5.39% and falling to 5.14% in late September.

Economic fundamentals remained quite robust during the reporting period.
Employment numbers averaging 298,000 non-farm payroll job additions per month,
real gross domestic product ("GDP") growth around the 3% level, and robust
consumer confidence measures began to weigh on the market. This resulted in a
back-up in yields from the September lows. The three- and six-month Treasury
bills climbed from their late September lows to December peaks of 5.47% and
5.56%, respectively. Counter-balancing the strong economic growth was the dearth
of inflationary pressures, including contracting producer prices and benign
consumer prices. The inflation picture, coupled with market technicals, kept a
lid on Treasury security yields. Yields drifted lower in January 1998 and the
three-month Treasury bill ended the reporting period just 10 basis points lower
than where it stood at the beginning of the reporting period, at 5.18%. The
six-month Treasury bill did likewise and ended the reporting period with a yield
just 16 basis points below its yield on August 1, 1997, at 5.23%. Over the
entire reporting period, the slope of the front-end of the yield curve flattened
by 18 basis points. Most of this flattening came as a result of the one-year
Treasury bill; its yield began the reporting period at 5.49% and ended at 5.26%.

While it was clear that the U.S. economy was exceptionally healthy, the impact
of the Asian crisis looms on the horizon. The financial difficulties being
experienced by several Asian nations is likely to impact the U.S. in the form of
reduced demand for our exports and increased competition from imports. This
suggests that the growth of economic activity in the U.S. will moderate from
current strong levels.

The fund remained targeted in a 35- to 45-day average maturity range throughout
the reporting period, and positioned itself within that range according to
relative value opportunities. The fund's portfolio is barbelled in structure,
which continued to provide a competitive yield. On January 31, 1998, 23% of the
fund was invested in U.S. government agency floating rate notes, including a
position in a Student Loan Marketing Association master note. The master note
helped to provide liquidity for the fund. This floating rate position was
combined with short-term agency discount notes to comprise the short-end of the
barbell. The fund combined this short position with Treasury and agency
securities with longer maturities of 6- to 12-months.

The fund most likely will continue to remain in its neutral, 35- to45-day
average maturity range as the economic backdrop continues to show mixed signals
of robust economic growth and subdued inflationary pressures. Changing economic
and market developments are continuously monitored, and performance is maximized
through on-going relative value analysis, to best serve clients attracted to the
short-term U.S. government market.

* An AAAm rating is obtained after S&P evaluates a number of factors, including
credit quality, market price exposure and management. S&P monitors the portfolio
weekly for developments that could cause changes in the ratings. Money market
funds and bond funds rated Aaa by Moody's Investors Service, Inc. are judged to
be of an investment quality similar to Aaa-rated fixed income obligations, that
is, they are judged to be of the best quality. These ratings do not remove
market risks and are subject to change.

                        NOTES TO FINANCIAL STATEMENTS

                  GOVERNMENT OBLIGATIONS TAX-MANAGED FUND

                        JANUARY 31, 1998 (UNAUDITED)

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of six portfolios. The financial
statements included herein are only those of Government Obligations Tax-Managed
Fund (the "Fund"). The financial statements of the other portfolios are
presented separately. The assets of each portfolio are segregated and a
shareholder's interest is limited to the portfolio in which shares are held. The
investment objective of the Fund is to provide current income consistent with
stability of principal and liquidity.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses, and revenues reported in
the financial statements. Actual results could differ from those estimated.

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares. At January 31, 1998, capital paid-in aggregated $1,561,925,706.
Transactions in shares were as follows:

TRANSFER AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES

PRESIDENT'S MESSAGE

Dear Shareholder:

I am pleased to present the Semi-Annual Report to Shareholders for Prime
Obligations Fund, a portfolio of Money Market Obligations Trust. This report
covers the first half of the fund's fiscal year, which is the six-month period
ended January 31, 1998. It begins with an investment review of the short-term
market from the fund's portfolio manager. Following the investment review are
the fund's portfolio of investments and financial statements.

Over the six-month reporting period, dividends paid to shareholders of
Institutional Shares and Institutional Service Shares each totaled $0.03 per
share. At the end of the reporting period, net assets reached $7.3 billion.

In Prime Obligations Fund, your ready cash is at work pursuing daily income
along with the additional advantages of daily liquidity and stability of
principal.* At the end of the reporting period, the fund's portfolio was
invested across a wide range of high-quality, short-term money market
securities, including commercial paper (38.8%), variable rate instruments
(19.6%), repurchase agreements (19.2%), certificates of deposit (7.6%),
short-term notes (7.7%), and time deposits (7.2%).

Thank you for your confidence in the daily earning power of Prime Obligations
Fund. Your questions and comments are always welcome.

Sincerely,

[Graphic]

J. Christopher Donahue
President
March 15, 1998

* Money market funds seek to maintain a stable net asset value of $1.00 per
share. There is no assurance that they will be able to do so. An investment
in the fund is not insured or guaranteed by the U.S. government.

INVESTMENT REVIEW

Prime Obligations Fund invests in money market instruments maturing in thirteen
months or less. The average maturity of these securities, computed on a
dollar-weighted basis, is restricted to 90 days or less. Portfolio securities
must be rated in the highest short-term rating category by one or more of the
nationally recognized statistical rating organizations or be of comparable
quality to securities having such ratings. Typical security types include, but
are not limited to: commercial paper, certificates of deposit, time deposits,
variable rate instruments, and repurchase agreements.

Growth during 1997 continued at an above-average pace, slowing only moderately
during the third quarter. Specifically, third quarter gross domestic product
("GDP") registered 3.1% while fourth quarter GDP climbed back up to 3.9%.
Despite the high growth, inflation remained subdued by all measures. The
consumer price index rose just 1.6% on an annualized basis for the six-month
period ended January 31, 1998. For the same time period, the producer price
index actually declined 0.9%, due mostly to a decline in energy prices, while
the employment cost index grew at an annualized 3.7% pace during the second half
of 1997.

Thirty-day commercial paper started the reporting period at 5.53% on August 1,
1997, and then rose as high as 5.98% on December 29, 1997, reflecting year-end
technical pressures. Rates fell back off again in January 1998 with 30-day
commercial paper settling in at the 5.50% level.

The money market yield curve flattened throughout the reporting period.
One-month commercial paper rates declined one basis point while six-month rates
declined 14 basis points reflecting the concern in the market about the Asian
contagion and its overall effect on U.S. growth.

The target average maturity range for the fund remained 35-45 days throughout
the reporting period, reflecting neutral economic and monetary sentiment. In
structuring the fund, there was continued emphasis placed on positioning 30-35%
of the fund's assets in variable rate demand notes and accomplishing a modest
barbell structure.

During the six-month period ended January 31, 1998, net assets of the fund
increased from $5.8 to $7.3 billion while the seven-day net yield increased from
5.49% to 5.53% for the Institutional Shares,* and from 5.24% to 5.28% for
Institutional Service Shares.* The effective average maturity of the fund on
January 31, 1998, was 42 days.

* Performance quoted represents past performance and is not indicative of future
results. Yield will vary. Yields quoted for money market funds most closely

NOTES TO FINANCIAL STATEMENTS
PRIME OBLIGATIONS FUND
JANUARY 31, 1998 (UNAUDITED)

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of six portfolios. The financial
statements included herein are only those of Prime Obligations Fund (the
"Fund"), a diversified portfolio. The financial statements of the other
portfolios are presented separately. The assets of each portfolio are segregated
and a shareholder's interest is limited to the portfolio in which shares are
held. The investment objective of the Fund is to provide current income
consistent with stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System, or to have
segregated within the custodian bank's vault, all securities held as collateral
under repurchase agreement transactions. Additionally, procedures have been
established by the Fund to monitor, on a daily basis, the market value of each
repurchase agreement's collateral to ensure that the value of collateral at
least equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/ dealers, which are deemed by
the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less than
the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon registration
under federal securities laws or in transactions exempt from such registration.
Many restricted securities may be resold in the secondary market in transactions
exempt from registration. In some cases, the restricted securities may be resold
without registration upon exercise of a demand feature. Such restricted
securities may be determined to be liquid under criteria established by the
Board of Trustees. The Fund will not incur any registration costs upon such
resales. Restricted securities are valued at amortized cost in accordance with
Rule 2a-7 under the Investment Company Act of 1940.

                             PRESIDENT'S MESSAGE

Dear Shareholder:

I am pleased to present the Semi-Annual Report to Shareholders for Tax-Free
Obligations Fund, a portfolio of Money Market Obligations Trust. This report
covers the first half of the fund's fiscal year, which is the six-month period
ended January 31, 1998. It begins with an investment review of the short-term
tax-free market from the fund's portfolio manager. Following the investment
review are the fund's portfolio of municipal bond investments and financial
statements.

Over the six-month reporting period, tax-free dividends paid to shareholders of
the fund's Institutional Shares and Institutional Service Shares each totaled
$0.02 per share. At the end of the reporting period, net assets surpassed the
$2.5 billion mark.

In Tax-Free Obligations Fund, your ready cash is at work pursuing daily income
free of federal income tax*--along with the additional advantages of daily
liquidity and stability of principal**--by investing in short-term municipal
securities.

Thank you for your confidence in the daily earning power of Tax-Free Obligations
Fund. Your questions and comments are always welcome.

Sincerely,

[Graphic]

J. Christopher Donahue
President
March 15, 1998

** Money market funds seek to maintain a stable net asset value of $1.00 per
   share. There is no assurance that they will be able to do so. An investment
   in the fund is not insured or guaranteed by the U.S. government.

                              INVESTMENT REVIEW

Tax-Free Obligations Fund invests in high-quality, short-term tax-exempt debt
securities and seeks to maintain a stable net asset value of $1.00 per share.
The Fund is rated AAA by Fitch IBCA, Inc. ("Fitch").* For the six-month
reporting period ended January 31, 1998, the Fund's net assets increased from
$2.1 billion to $2.5 billion. As of January 31, 1998, the effective average
maturity was 45 days.

The U.S. economy was robust in 1997 with gross domestic product ("GDP") growing
at 3.9%. At the same time, inflationary pressures remained benign falling to
1.9%, while the unemployment rate fell to below 5.0%. Despite the tightening in
the labor markets and strong domestic demand, the Federal Reserve Board (the
"Fed") did not further raise interest rates in 1997 after its quarter point
nudge in March 1997. Healthy productivity growth, weak commodity prices, and
declining import prices resulting from the Asian crisis most likely eliminated
any Fed rate increase during the six-month period.

Movements in short-term interest rates in the second half of 1997 reflected the
market's shifting sentiment on Fed policy. The one-year Treasury bill traded as
high as 5.60% in August as investors feared a rate hike. However, as the
economic news from the Pacific Rim worsened, the one-year Treasury-bill rate
fell to 5.20% by the close of the reporting period. Investors believed that the
impact of the Asian crisis would cause GDP to slow dramatically in 1998.
However, at the end of the reporting period, in late January, the market
received news that the U.S. economy was accelerating. This caused market
sentiment, on the strength of the economy, to reverse again causing one-year
Treasury bills to go back up to 5.50% levels.

In addition to economic fundamentals, short-term municipal securities were
strongly influenced by technical factors over this reporting period, notably the
end of the summer note issuance season and year-end cash flows. Variable rate
demand notes ("VRDNs"), which comprise more than 50% of the fund's assets,
started the reporting period in the 3.40% range, but moved sharply higher in
September to above 4.00% as supply and demand imbalances occurred. Yields then
declined in October before rising to the 4.00% range at year end due to
traditional year end selling pressures. In early January 1998, as participants
looked to reinvest large coupon payments and heavy cash inflows, VRDN yields
fell and ended the reporting period where they began, in the 3.40% range. Over
the six-month reporting period, VRDN yields averaged roughly 67% of taxable
rates making them attractive for investors at the 35% or higher federal tax
brackets.

As long as inflation remains benign, the Fed should be content to sit on the
sidelines until confronted with signs of overriding strength or considerable
weakness in economic growth. The average maturity of the fund will continue to
be managed in accordance with our expectation for a stable monetary policy in
the near term. The average maturity target of 45-50 days reflects our neutral
stance. Nevertheless, we are vigilant in our watch of market developments to
best serve our municipal money market clients.

* Fitch's money market fund ratings are an assessment of the safety of invested
  principal and the ability to maintain a stable market value of the fund's
  shares. Ratings are based on an evaluation of several factors, including
  credit quality, diversification, and maturity of assets in the portfolio, as
  well as management strength and operational capabilities. This rating,
  however, is subject to change and does not remove market risks.

(a) The Fund may only invest in securities rated in one of the two highest
    short-term rating categories by nationally recognized statistical rating
    organizations ("NRSROs") or unrated securities of comparable quality. An
    NRSRO's two highest rating categories are determined without regard for
    sub-categories and gradations. For example, securities rated SP-1+, SP-1, or
    SP-2 by Standard & Poor's, MIG-1, or MIG-2 by Moody's Investors Service,
    Inc., F-1+, F-1, and F-2 by Fitch IBCA, Inc. are all considered rated in one
    of the two highest short-term rating categories. Securities rated in the
    highest short-term rating category (and unrated securities of comparable
    quality) are identified as First Tier securities. Securities rated in the
    second highest short-term rating category (and unrated securities of
    comparable quality) are identified as Second Tier securities. The Fund
    follows applicable regulations in determining whether a security is rated
    and whether a security rated by multiple NRSROs in different rating
    categories should be identified as a First or Second Tier security. At
    January 31, 1998, the portfolio securities were rated as follows:

Tier Rating Based on Total Market Value (Unaudited)

 FIRST TIER   SECOND TIER
   100.00%       0.00%
(b) Denotes a restricted security which is subject to restrictions on resale
    under Federal Securities laws. At January 31, 1998, these securities
    amounted to $36,785,000 which represents 1.5% of net assets.

(c) Cost for federal tax purposes $2,524,025,703.

Note: The categories of investments are shown as a percentage of net assets
($2,515,090,079) at January 31, 1998.

                        NOTES TO FINANCIAL STATEMENTS

                         TAX-FREE OBLIGATIONS FUND

                        JANUARY 31, 1998 (UNAUDITED)

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of six portfolios. The financial
statements included herein are only those of Tax-Free Obligations Fund (the
"Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held. The investment
objective of the Fund is to provide dividend income exempt from federal regular
income tax consistent with the stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

The Fund's use of the amortized cost method to value its portfolio securities is
in accordance with Rule 2a-7 under the Act.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

At July 31, 1997, the Fund, for federal tax purposes, had a capital loss
carryforward of $163,650, which will reduce the Fund's taxable income arising
from future net realized gain on investments, if any, to the extent permitted by
the Code, and thus will reduce the amount of the distributions to shareholders
which would otherwise be necessary to relieve the Fund of any liability for
federal tax. Pursuant to the Code, such capital loss carryforward will expire as
follows:

 EXPIRATION YEAR     EXPIRATION AMOUNT
           2001             $ 580
           2002            19,220
           2004            36,269
           2005           107,581
Additionally, net capital losses of $16,488 attributable to security
transactions incurred after October 31, 1996, are treated as arising on the
first day of the Fund's next taxable year.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon restoration
under federal securities laws or in transactions exempt from such registration.
Many restricted securities may be resold in the secondary market in transactions
exempt from registration upon exercise or a demand feature. Such restricted
securities may be determined to be liquid under criteria established by the
Board of Trustees. The Fund will not incur any registration costs upon such
resales. Restricted securities are valued at amortized cost in accordance with
Rule 2a-7 under the Investment Company Act of 1940.

Additional information on the restricted securities held at January 31, 1998 are
as follows:

                                                   ACQUISITION  ACQUISITION
SECURITY                                              DATE         COST
 Illinois Development Finance Authority, PT-131     10/2/1997   $ 6,000,000
 (Series 1995A)
 Maryland State Community Development               8/27/1997    27,540,000
 Administration, (Series 1997), PT-123
 Pennsylvania State University, PT-157 (Series      1/29/1998     3,245,000
 1992)

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses, and revenues reported in
the financial statements. Actual results could differ from those estimated.

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares. At January 31, 1998, capital paid-in aggregated $2,515,102,428.
Transactions in shares were as follows:

INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY FEE

Federated Management, the Fund's investment adviser (the "Adviser"), receives
for its services an annual investment advisory fee equal to 0.20% of the Fund's
average daily net assets. The Adviser may voluntarily choose to waive any

                             PRESIDENT'S MESSAGE

Dear Shareholder:

I am pleased to present the Semi-Annual Report to Shareholders for Treasury
Obligations Fund, a portfolio of Money Market Obligations Trust. This report
covers the first half of the fund's fiscal year, which is the six-month period
ended January 31, 1998. It begins with an investment review of the short-term
Treasury market from the fund's portfolio manager. Following the investment
review are the fund's portfolio of investments and financial statements.

Over the six-month reporting period, dividends paid to shareholders of the
fund's Institutional Shares, Institutional Service Shares, and Institutional
Capital Shares, each totaled $0.03 per share. At the end of the reporting
period, net assets topped the $10 billion mark.

In Treasury Obligations Fund, your ready cash is at work pursuing daily
income--along with the additional advantages of daily liquidity and stability of
principal*--by investing exclusively in short-term U.S Treasury obligations and
in repurchase agreements collateralized by these obligations.

Thank you for your confidence in the daily earning power of Treasury Obligations
Fund. As always, your questions and comments are welcome.

Sincerely,

J. Christopher Donahue

* Money market funds seek to maintain a stable net asset value of $1.00 per
  share. There is no assurance that they will be able to do so. An investment
  in the fund is not insured or guaranteed by the U.S. government.

                              INVESTMENT REVIEW

Treasury Obligations Fund, which is rated AAAm* by Standard & Poor's ("S&P") and
Aaa* by Moody's Investors Service, Inc., ("Moody's") is invested in direct
obligations of the U.S. Treasury either in the form of notes and bills or as
collateral for repurchase agreements. Recently, the fund has been managed within
a 35- to 45-day average maturity range, a neutral stance for the fund.

Over the six-month period ended January 31, 1998, the Federal Reserve Board (the
"Fed") stood pat in the face of economic growth that continued to exceed the
2.5% pace thought to be the non-inflationary potential. The federal funds target
remained at 5.5%, where it has been since the Fed tightened monetary policy in
March 1997. With gross domestic product ("GDP") growth at 3.1% over the third
quarter of 1997, expectation was built for the need for an additional tightening
from the Fed as added insurance against inflation. However, dramatic declines in
the Asian equity markets curtailed this expectation, and overseas developments
dominated the rest of the fourth quarter of 1997. Although GDP growth expanded
at close to 4.0% over this period, the Fed kept monetary policy unchanged.

Aside from economic fundamentals, movements in short-term interest rates on
Treasury securities were driven by other factors as well over the reporting
period. The yield on the three-month Treasury bill, for example, began the
period at 5.2% and traded down to 4.9% by late September in response to
quarter-end window-dressing and a reduction in the overall supply of Treasury
bills. It rose briefly to 5.1% in early October, but was driven downward to
below 5.0% again as the alarming declines in the overseas markets resulted in a
flight-to-quality to Treasuries. The yield rose to 5.2% by early November as the
immediate crisis subsided, and then climbed steadily to 5.4% as overseas
investors--primarily Japanese--sold their Treasury holdings to help meet
liquidity needs back home. Early in January 1998, the pendulum swung back again,
as growing speculation that the impact on the domestic economy from the troubles
in Asia might be so great that the Fed might actually have to ease monetary
policy gripped the market. The yield on the three-month Treasury bill fell again
to 5% as a result. These fears receded somewhat by mid-month, and the yield rose
to close the reporting period at 5.2%. Movements in longer-term securities in
the money market universe (i.e., those between six months and one year) were
slightly less affected by the technical supply and flight-to-quality influences,
but traded overall along with the shorter security and maintained a healthy bid.

The fund was targeted in a 35- to 45-day average maturity range over the
reporting period, essentially a neutral stance for the portfolio. Once an
average maturity range was established, the fund maximized performance through
ongoing relative value analysis. The fund's structure remained barbelled over
the reporting period, as a yield advantage continued to exist for repurchase
agreements relative to other short-term investments. The fund combined a
significant percentage in these repurchase agreements--primarily on an overnight
basis--with purchases of securities with 6- to 12-month maturities. This
portfolio structure continued to provide a competitive yield.

The risks to the Fed at this juncture appear to be balanced, with the threat of
higher inflation stemming from tight labor markets being potentially offset by
the as-yet-unknown impact of the Asian "flu." The Fed should be content to "wait
and see" until the effects on the domestic economy are better understood - which
should become more clear over the second quarter of 1998. We would expect to
maintain our current neutral positioning over this period. However, changing
economic and market developments are continuously monitored to best serve our
clients attracted to the short term U.S. government market.

* An AAAm rating is obtained after S&P evaluates a number of factors, including
  credit quality, market price exposure, and management. S&P monitors the
  portfolio weekly for developments that could cause changes in the ratings.
  Money market funds and bond funds rated Aaa by Moody's are judged to be of an
  investment quality similar to Aaa-rated fixed-income obligations, that is,
  they are judged to be of the best quality. These ratings do not remove market
  risks and are subject to change.

                        NOTES TO FINANCIAL STATEMENTS

                         TREASURY OBLIGATIONS FUND

                        JANUARY 31, 1998 (UNAUDITED)

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of six portfolios. The financial
statements included herein are only those of Treasury Obligations Fund (the
"Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held. The investment
objective of the Fund is current income consistent with stability of principal.

The Fund offers three classes of shares: Institutional Shares, Institutional
Service Shares, and Institutional Capital Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

The Fund's use of the amortized cost method to value its portfolio securities is
in accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System, or to have
segregated within the custodian bank's vault, all securities held as collateral
under repurchase agreement transactions. Additionally, procedures have been
established by the Fund to monitor, on a daily basis, the market value of each
repurchase agreement's collateral to ensure that the value of collateral at
least equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed by
the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less than
the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses, and revenues reported in
the financial statements. Actual results could differ from those estimated.

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares. At January 31, 1998, capital paid-in aggregated
$10,005,969,348. Transactions in shares were as follows:

Mutual funds are not bank deposits or obligations, are not guaranteed by any
bank, and are not insured or guaranteed by the U.S. government, the Federal
Deposit Insurance Corporation, the Federal Reserve Board, or any other
government agency. Investment in mutual funds involves investment risk,
including possible loss of principal. Although money market funds seek to
maintain a stable net asset value of $1.00 per share, there is no assurance that
they will be able to do so.
