DEAR
Shareholder,

[PHOTO OF TIMOTHY R. SCHWERTFEGER APPEARS HERE]
Timothy R. Schwertfeger

Harvard University, Tiffany's and Dom Perignon are each the Rolls-Royce of its
market. Each is synonymous with "quality." Each has established, reinforced and
marketed its brand as one that consistently delivers a quality product -- be it
education, fine jewelry or champagne. Each has made a promise to its customers,
and each works hard to keep that promise, year after year.

Webster defines quality as the degree of excellence that a thing possesses.
Nuveen Investments defines quality by the excellence of our portfolio
management and products as well as of the financial advisors you, and our firm,
work with.

Quality Portfolio Management and Products

Nuveen's income-oriented funds feature portfolio management by Nuveen
Investment Management (NIM). NIM follows a disciplined, research-driven
investment approach to uncover income securities that combine exceptional
relative value with above-average return potential. Drawing on 300 combined
years of investment experience, the Nuveen team of portfolio managers and
research analysts offers:

 . A commitment to exhaustive research
 . An active, value-oriented investment style
 . The unmatched presence of trading leverage of a market leader.

     While you may be familiar with our municipal bond funds, you may not be
aware of the equity mutual funds we offer investors. Our two newest funds --
Nuveen Innovation and Nuveen International Growth -- were launched in December
1999. These funds are managed by Columbus Circle Investors (CCI), a firm that
has been managing money for more than 25 years and has used a single,
disciplined investment philosophy called "Positive Momentum and Positive
Surprise." This philosophy is based on the premise that:

 . Strong companies tend to get stronger. CCI believes a company that
  demonstrates positive momentum in its business fundamentals tends to generate
  superior returns through rising stock prices. This represents the Positive
  Momentum CCI seeks.

 . Companies positively surprise when their business fundamentals and reported
  results exceed investor and analyst expectations. CCI believes this is often
  accompanied by strong, accelerating growth. This represents the Positive
  Surprise CCI seeks.

     Our Nuveen Rittenhouse Growth Fund is managed by Rittenhouse Financial
Services, Inc., a wholly owned subsidiary of the John Nuveen Company. The
investment philosophy Rittenhouse established years ago remains firmly in place
today -- pursue long-term growth with high-quality, large capitalization blue
chip stocks. This singular focus has translated into consistently strong
risk-adjusted returns and productive, long-lasting relationships.

Timothy R. Schwertfeger
Chairman of the Board

     We also offer several growth and income style funds, all managed by
Institutional Capital Corporation (ICAP), of which the John Nuveen Company holds
a minority interest. ICAP seeks out stocks it believes have appreciation
potential unrecognized by the general market for Nuveen Growth and Income Stock
Fund, Nuveen European Value Fund, Nuveen Balanced Stock and Bond Fund and Nuveen
Balanced Municipal and Stock Fund.

Quality Financial Advisors

Nuveen Investments works through financial advisors because we believe in
quality advice. Today, you face an unprecedented array of investment choices,
opportunities -- and risks. Your investment advisor can offer you the
professional assistance that will help bring to life your aspirations -- for
yourself and your family, today and in the future.

NUVEEN MUNICIPAL FUNDS

Market Commentary as of August 31, 2000

Municipal bonds performed well during the six-month period ended August 31,
2000. During this period, yields on long-term municipal bonds declined by
approximately 54 basis points, resulting in a corresponding rise in bond prices.

     Three reasons account for this performance. First, the likelihood of a
Federal Reserve tightening -- in the view of the general market -- fell as signs
of inflation did not appear. Secondly, new issue supply in the municipal market
remained low. This was due in part to the fact that many municipalities have
been funding capital projects with current strong tax collections rather than
with long-term debt. Finally, volatility and lack- luster returns in the equity
market have increasingly turned investor attention to the municipal market.

     During the period, credit spreads -- the basis point difference between
yields on high-grade bonds and low-grade bonds -- tightened. Still, compared
with credit spreads over the last several years, the spreads remained
attractive. Liquidity spreads -- the basis point difference between the yields
offered by sellers and yields demanded by buyers -- remained wide and volatile
creating opportunities for value trading.

     The strong economy continued to generate strong tax collections for
municipalities throughout the country. In addition to reducing the need for debt
issuance, the collections have contributed to improved credit quality among many
municipal issuers. The recent upgrade of New York City to A, its highest rating
in 25 years, illustrates this trend.

     Among the noteworthy deals this quarter were two tobacco settlement-backed
bond issues, both on behalf of New York counties. In the $206 billion settlement
between 46 states and major tobacco companies, the states exchanged all smoking-
related claims for a stream of annual payments from the tobacco companies.
Several states and counties have come to market to borrow against the future
stream of payments. Proceeds of these transactions have been applied to several
different municipal purposes. We expect to see many more tobacco deals over the
next year.

A Look Ahead

We believe the Fed will remain on hold through the elections. As the
traditionally slow time of the year for the bond market -- summer -- has ended,
supply could increase incrementally. However, supply will likely remain
significantly below last year because of strong tax collections. Finally, we
believe that investors will increasingly shift money from the equity market to
the bond market if they see equity returns significantly lower than the past
several years.

Notes to Financial Statements (Unaudited)






1. General Information and Significant Accounting Policies

The Nuveen Money Market Fund (the "Fund") is a series of the Nuveen Money Market
Trust (the "Trust") which was organized as a Massachusetts business trust on
January 15, 1999. The Trust (and each series within the Trust) is an open-end,
diversified management investment company registered under the Investment
Company Act of 1940.

The Fund invests substantially all of its assets in a diversified portfolio of
high quality money market instruments for current income, the stability of
principal and the maintenance of liquidity.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The Fund invests in short-term securities maturing within one year from the date
of acquisition. Securities with a maturity of more than one year in all cases
have variable rate and demand features qualifying them as short-term securities
and are valued at amortized cost. On a dollar-weighted basis, the average
maturity of all such securities must be 90 days or less (at August 31, 2000, the
dollar-weighted average life was 7.21 days).

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject
to market fluctuation during this period. The Fund has instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
August 31, 2000, the Fund had no such outstanding purchase commitments.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts.

Dividends and Distributions to Shareholders

Net investment income is declared as a dividend to shareholders of record as of
the close of each business day and payment is made or reinvestment is credited
to shareholder accounts after month-end. Net realized capital gains from
investment transactions, if any, are declared and distributed to shareholders
annually. Furthermore, capital gains are distributed only to the extent they
exceed available capital loss carryforwards.

Federal Income Taxes

The Fund intends to distribute all net ordinary taxable income and net realized
capital gains from investment transactions, if any, and to otherwise comply with
the requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies. Therefore, no federal tax provision is
required.

Flexible Sales Charge Program

The Fund offers Class A, B, C and R Shares. Class A Shares incur an annual 12b-1
service fee and under limited circumstances may be subject to a contingent
deferred sales charge ("CDSC"). Class B Shares incur annual 12b-1 distribution
and service fees. An investor purchasing Class B Shares agrees to pay a CDSC of
up to 5% depending upon the length of time the shares are held by the investor
(CDSC is reduced to 0% at the end of six years). Class B Shares convert to Class
A Shares eight years after purchase. Class C Shares incur annual 12b-1
distribution and service fees. An investor purchasing Class C Shares agrees to
pay a CDSC of 1% if Class C Shares are redeemed within one year of purchase.
Class R Shares are not subject to any sales charge or 12b-1 distribution or
service fees. Class R Shares are available only under limited circumstances.

Insurance

The Fund has purchased liability insurance to protect against a decline in the
value of securities held in the Fund's portfolio caused by the default of
securities owned by the Fund. The insurance covers substantially all of the
Fund's investments except U.S. Government securities. The maximum total
coverage for all Nuveen money market funds is $50 million, with certain
deductibles for each loss. The Fund pays the policy premiums. Coverage under the
policy is subject to certain conditions and may not be renewable upon
expiration. While the policy is intended to provide some protection against
credit risk and to help the Fund maintain a constant price per share of $1.00,
there is no guarantee that the insurance will do so.

Derivative Financial Instruments

The Fund may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the six months ended August 31, 2000.

Custodian Fee Credit

The Fund has an agreement with the custodian bank whereby certain custodian fees
and expenses are reduced by credits earned on the Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

in an amount necessary to prevent the Fund's total operating expenses (including
the management fee, but excluding interest, taxes, fees incurred in acquiring
and disposing of portfolio securities, any 12b-1 distribution or service fees
and, to the extent permitted, extraordinary expenses) from exceeding .65 of 1%
of the average daily net assets of the Fund. The Adviser may modify or
discontinue these waivers and reimbursements at any time.

DEAR

Shareholder,

[PHOTO OF Timothy R. Schwertfeger APPEARS HERE]
Chairman of the Board

Harvard University, Tiffany's and Dom Perignon are each the Rolls-Royce of its
market. Each is synonymous with "quality." Each has established, reinforced and
marketed its brand as one that consistently delivers a quality product --be it
education, fine jewelry or champagne. Each has made a promise to its customers,
and each works hard to keep that promise, year after year.

Webster defines quality as the degree of excellence that a thing possesses.
Nuveen Investments defines quality by the excellence of our portfolio management
and products as well as of the financial advisors you, and our firm, work with.

Quality Portfolio Management and Products

Nuveen's income-oriented funds feature portfolio management by Nuveen Investment
Management (NIM). NIM follows a disciplined, research-driven investment approach
to uncover income securities that combine exceptional relative value with
above-average return potential. Drawing on 300 combined years of investment
experience, the Nuveen team of portfolio managers and research analysts offers:

 .  A commitment to exhaustive research
 .  An active, value-oriented investment style
 .  The unmatched presence of trading leverage of a market leader.

     While you may be familiar with our municipal bond funds, you may not be
aware of the equity mutual funds we offer investors. Our two newest funds--
Nuveen Innovation and Nuveen International Growth -- were launched in December
1999. These funds are managed by Columbus Circle Investors (CCI), a firm that
has been managing money for more than 25 years and has used a single,
disciplined investment philosophy called "Positive Momentum and Positive
Surprise." This philosophy is based on the premise that:

 .  Strong companies tend to get stronger. CCI believes a company that
   demonstrates positive momentum in its business fundamentals tends to generate
   superior returns through rising stock prices. This represents the Positive
   Momentum CCI seeks.

 .  Companies positively surprise when their business fundamentals and reported
   results exceed investor and analyst expectations. CCI believes this is often
   accompanied by strong, accelerating growth. This represents the Positive
   Surprise CCI seeks.

     Our Nuveen Rittenhouse Growth Fund is managed by Rittenhouse Financial
Services, Inc., a wholly owned subsidiary of the John Nuveen Company. The
investment philosophy Rittenhouse established years ago remains firmly in place
today -- pursue long-term growth with high-quality, large capitalization blue
chip stocks. This singular focus has translated into consistently strong
risk-adjusted returns and productive, long-lasting relationships.

                                                        SEMIANNUAL REPORT page 1
<PAGE>

     We also offer several growth and income style funds, all managed by
Institutional Capital Corporation (ICAP), of which the John Nuveen Company holds
a minority interest. ICAP seeks out stocks it believes have appreciation
potential unrecognized by the general market for Nuveen Growth and Income Stock
Fund, Nuveen European Value Fund, Nuveen Balanced Stock and Bond Fund and Nuveen
Balanced Municipal and Stock Fund.

Quality Financial Advisors

Nuveen Investments works through financial advisors because we believe in
quality advice. Today, you face an unprecedented array of investment choices,
opportunities -- and risks. Your investment advisor can offer you the
professional assistance that will help bring to life your aspirations -- for
yourself and your family, today and in the future.

Please review your fund's Financial Spotlight to learn how it is positioned as
of its semiannual period, ended August 31, 2000. Also, I invite you to read the
following Market Commentary to learn more about the economic environment in
which your fund performed.

your financial advisor. Or call Nuveen at (800) 621-7227 or visit our Internet
site at www.nuveen.com. Please read the prospectus carefully before you invest
or send money.

Thank you for your continued confidence.



Sincerely,


/s/ Timothy R. Schwertfeger

NUVEEN MUNICIPAL FUNDS

Market Commentary as of August 31, 2000

Municipal bonds performed well during the six-month period ended August 31,
2000. During this period, yields on long-term municipal bonds declined by
approximately 54 basis points, resulting in a corresponding rise in bond prices.

     Three reasons account for this performance. First, the likelihood of a
Federal Reserve tightening -- in the view of the general market -- fell as signs
of inflation did not appear. Secondly, new issue supply in the municipal market
remained low. This was due in part to the fact that many municipalities have
been funding capital projects with current strong tax collections rather than
with long-term debt. Finally, volatility and lack-luster returns in the equity
market have increasingly turned investor attention to the municipal market.

     During the period, credit spreads -- the basis point difference between
yields on high-grade bonds and low-grade bonds -- tightened. Still, compared
with credit spreads over the last several years, the spreads remained
attractive. Liquidity spreads -- the basis point difference between the yields
offered by sellers and yields demanded by buyers --remained wide and volatile
creating opportunities for value trading.

     The strong economy continued to generate strong tax collections for
municipalities throughout the country. In addition to reducing the need for debt
issuance, the collections have contributed to improved credit quality among many
municipal issuers. The recent upgrade of New York City to A, its highest rating
in 25 years, illustrates this trend.

     Among the noteworthy deals this quarter were two tobacco settlement-backed
bond issues, both on behalf of New York counties. In the $206 billion settlement
between 46 states and major tobacco companies, the states exchanged all
smoking-related claims for a stream of annual payments from the tobacco
companies. Several states and counties have come to market to borrow against the
future stream of payments. Proceeds of these transactions have been applied to
several different municipal purposes. We expect to see many more tobacco deals
over the next year.

A Look Ahead

We believe the Fed will remain on hold through the elections. As the
traditionally slow time of the year for the bond market -- summer -- has ended,
supply could increase incrementally. However, supply will likely remain
significantly below last year because of strong tax collections. Finally, we
believe that investors will increasingly shift money from the equity market to
the bond market if they see equity returns significantly lower than the past
several years.

Notes to Financial Statements (Unaudited)


1. General Information and Significant Accounting Policies

The Nuveen Institutional Tax-Exempt Money Market Fund (the "Fund") formerly, the
Nuveen Tax-Exempt Money Market Fund, Inc., is a series of the Nuveen Money
Market Trust (the "Trust") which was organized as a Massachusetts business trust
on January 15, 1999. Nuveen Tax-Exempt Money Market Fund, Inc. was reorganized
effective after the close of business on June 25, 1999, as previously approved
by shareholders. The Trust (and each series within the Trust) is registered
under the Investment Company Act of 1940 as an open-end, management investment
company.

The Fund invests substantially all of its assets in a diversified portfolio of
high quality, tax-exempt money market instruments for current income, the
stability of principal, and the maintenance of liquidity.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The Fund invests in short-term municipal securities maturing within one year
from the date of acquisition. Securities with a maturity of more than one year
in all cases have variable rate and demand features qualifying them as short-
term securities and are valued at amortized cost. On a dollar-weighted basis,
the average maturity of all such securities must be 90 days or less (at August
31, 2000, the dollar-weighted average life was 41.68 days).

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
August 31, 2000, the Fund had an outstanding delayed delivery purchase
commitment of $5,767,962.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared as a dividend to shareholders of
record as of the close of each business day and payment is made or reinvestment
is credited to shareholder accounts after month-end. Net realized capital gains
from investment transactions and/or net ordinary taxable income, if any, are
declared and distributed to shareholders annually. Furthermore, capital gains
are distributed only to the extent they exceed available capital loss
carryforwards.

Federal Income Taxes

The Fund intends to distribute all of its tax-exempt net investment income,
taxable ordinary income and/or net realized capital gains from investment
transactions, if any, and to otherwise comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies. Therefore, no federal income tax provision is required. Furthermore,
the Fund intends to satisfy conditions which will enable interest from municipal
securities, which is exempt from regular federal income tax, to retain such tax-
exempt status when distributed to shareholders of the Fund. Net ordinary taxable
income and net realized capital gain distributions, if any, are subject to
federal taxation.

Insurance Commitments

The Fund has purchased liability insurance to protect against a decline in the
value of securities held in the Fund's portfolio caused by the default of
securities owned by the Fund. The insurance covers substantially all of the
Fund's investments except U.S. Government securities. The maximum total coverage
for all Nuveen money market funds is $50 million, with certain deductibles for
each loss. The Fund pays the policy premiums. Coverage under the policy is
subject to certain conditions and may not be renewable upon expiration. While
the policy is intended to provide some protection against credit risk and to
help the Fund maintain a constant price per share of $1.00, there is no
guarantee that the insurance will do so.

Notes to Financial Statements (Unaudited) (continued)


Derivative Financial Instruments

The Fund may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other finan-cial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the six months ended August 31, 2000.

Custodian Fee Credit

The Fund has an agreement with the custodian bank whereby certain custodian fees
and expenses are reduced by credits earned on the Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the finan-cial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

2. Securities Transactions

Purchases and sales (including maturities) of investments in short-term
municipal securities during the six months ended August 31, 2000, aggregated
$404,815,778 and $456,800,000, respectively.

At August 31, 2000, the cost of investments owned for federal income tax
purposes was the same as the cost for financial reporting purposes.

At February 29, 2000, the Fund's last fiscal year end, the Fund had unused
capital loss carryforwards of $44,203 available for federal income tax purposes
to be applied against future capital gains, if any. If not applied, $3,287 of
the carryforwards will expire in the year 2002, $15,535 will expire in the year
2003, $5,800 will expire in the year 2004, $17,809 will expire in the year 2007
and $1,772 will expire in the year 2008.

3. Management Fee and Other Transactions with Affiliates

Under the Fund's investment management agreement with Nuveen Advisory Corp. (the
"Adviser"), a wholly owned subsidiary of The John Nuveen Company, the Fund pays
an annual management fee, payable monthly, which is based upon the average daily
net assets of the Fund as follows:

Average Daily Net Assets                                          Management Fee
--------------------------------------------------------------------------------
For the first $125 million                                           .4000 of 1%
For the next $125 million                                            .3875 of 1
For the next $250 million                                            .3750 of 1
For the next $500 million                                            .3625 of 1
For the next $1 billion                                              .3500 of 1
For net assets over $2 billion                                       .3250 of 1
================================================================================

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Fund pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its officers, all of whom receive remuneration for their services
to the Fund from the Adviser or its affiliates.

4. Composition of Net Assets

At August 31, 2000, the Fund had an unlimited number of $.01 par value stock
authorized. Net assets consisted of $176,950,721 paid-in capital and $46,245 of
accumulated net realized loss from investment transactions.

Chairman of the Board

DEAR
Shareholder,

[PHOTO OF TIMOTHY R. SCHWERTFEGER CHAIRMAN OF THE BOARD APPEARS HERE]

Harvard University, Tiffany's and Dom Perignon are each the Rolls-Royce of its
market. Each is synonymous with "quality." Each has established, reinforced and
marketed its brand as one that consistently delivers a quality product -- be it
education, fine jewelry or champagne. Each has made a promise to its customers,
and each works hard to keep that promise, year after year.

Webster defines quality as the degree of excellence that a thing possesses.
Nuveen Investments defines quality by the excellence of our portfolio management
and products as well as of the financial advisors you, and our firm, work with.

Quality Portfolio Management and Products

Nuveen's income-oriented funds feature portfolio management by Nuveen Investment
Management (NIM). NIM follows a disciplined, research-driven investment approach
to uncover income securities that combine exceptional relative value with
above-average return potential. Drawing on 300 combined years of investment
experience, the Nuveen team of portfolio managers and research analysts offers:

 . A commitment to exhaustive research
 . An active, value-oriented investment style
 . The unmatched presence of trading leverage of a market leader.

     While you may be familiar with our municipal bond funds, you may not be
aware of the equity mutual funds we offer investors. Our two newest funds --
Nuveen Innovation and Nuveen International Growth -- were launched in December
1999. These funds are managed by Columbus Circle Investors (CCI), a firm that
has been managing money for more than 25 years and has used a single,
disciplined investment philosophy called "Positive Momentum and Positive
Surprise." This philosophy is based on the premise that:

 . Strong companies tend to get stronger. CCI believes a company that
  demonstrates positive momentum in its business fundamentals tends to generate
  superior returns through rising stock prices. This represents the Positive
  Momentum CCI seeks.

 . Companies positively surprise when their business fundamentals and reported
  results exceed investor and analyst expectations. CCI believes this is often
  accompanied by strong, accelerating growth. This represents the Positive
  Surprise CCI seeks.

     Our Nuveen Rittenhouse Growth Fund is managed by Rittenhouse Financial
Services, Inc., a wholly owned subsidiary of the John Nuveen Company. The
investment philosophy Rittenhouse established years ago remains firmly in place
today -- pursue long-term growth with high-quality, large capitalization blue
chip stocks. This singular focus has translated into consistently strong risk-
adjusted returns and productive, long-lasting relationships.


                                                        SEMIANNUAL REPORT page 1
<PAGE>

     We also offer several growth and income style funds, all managed by
Institutional Capital Corporation (ICAP), of which the John Nuveen Company holds
a minority interest. ICAP seeks out stocks it believes have appreciation
potential unrecognized by the general market for Nuveen Growth and Income Stock
Fund, Nuveen European Value Fund, Nuveen Balanced Stock and Bond Fund and Nuveen
Balanced Municipal and Stock Fund.

Quality Financial Advisors

Nuveen Investments works through financial advisors because we believe in
quality advice. Today, you face an unprecedented array of investment choices,
opportunities -- and risks. Your investment advisor can offer you the
professional assistance that will help bring to life your aspirations -- for
yourself and your family, today and in the future.

of its semiannual period, ended August 31, 2000. Also, I invite you to read the
following Market Commentary to learn more about the economic environment in
which your fund performed.

site at www.nuveen.com. Please read the prospectus carefully before you invest
or send money.

Sincerely,

/s/ Timothy R. Schwertfeger

NUVEEN MUNICIPAL FUNDS
Market Commentary as of August 31, 2000

Municipal bonds performed well during the six-month period ended August 31,
2000. During this period, yields on long-term municipal bonds declined by
approximately 54 basis points, resulting in a corresponding rise in bond prices.

     Three reasons account for this performance. First, the likelihood of a
Federal Reserve tightening -- in the view of the general market -- fell as signs
of inflation did not appear. Secondly, new issue supply in the municipal market
remained low. This was due in part to the fact that many municipalities have
been funding capital projects with current strong tax collections rather than
with long-term debt. Finally, volatility and lack-luster returns in the equity
market have increasingly turned investor attention to the municipal market.

     During the period, credit spreads -- the basis point difference between
yields on high-grade bonds and low-grade bonds -- tightened. Still, compared
with credit spreads over the last several years, the spreads remained
attractive. Liquidity spreads -- the basis point difference between the yields
offered by sellers and yields demanded by buyers --remained wide and volatile
creating opportunities for value trading.

     The strong economy continued to generate strong tax collections for
municipalities throughout the country. In addition to reducing the need for debt
issuance, the collections have contributed to improved credit quality among many
municipal issuers. The recent upgrade of New York City to A, its highest rating
in 25 years, illustrates this trend.

     Among the noteworthy deals this quarter were two tobacco settlement-backed
bond issues, both on behalf of New York counties. In the $206 billion settlement
between 46 states and major tobacco companies, the states exchanged all smoking-
related claims for a stream of annual payments from the tobacco companies.
Several states and counties have come to market to borrow against the future
stream of payments. Proceeds of these transactions have been applied to several
different municipal purposes. We expect to see many more tobacco deals over the
next year.

A Look Ahead

We believe the Fed will remain on hold through the elections. As the
traditionally slow time of the year for the bond market -- summer -- has ended,
supply could increase incrementally. However, supply will likely remain
significantly below last year because of strong tax collections. Finally, we
believe that investors will increasingly shift money from the equity market to
the bond market if they see equity returns significantly lower than the past
several years.

Notes to Financial Statements (Unaudited)

1. General Information and Significant Accounting Policies
The money market funds (the "Funds") covered in this report are Nuveen Municipal
Money Market Fund, Inc. ("Municipal"), formerly, Nuveen Tax-Free Reserves, Inc.,
Nuveen California Tax-Exempt Money Market Fund ("California"), formerly, Nuveen
California Tax-Free Money Market Fund and Nuveen New York Tax-Exempt Money
Market Fund ("New York"), formerly, Nuveen New York Tax-Free Money Market Fund.
Nuveen California Tax-Free Money Market Fund and Nuveen New York Tax-Free Money
Market Fund were reorganized after the close of business on June 25, 1999, as
previously approved by shareholders. As part of the reorganization of the Nuveen
California Tax-Free Money Market Fund, the Service Plan series and the
Institutional series were consolidated and renamed Class A in California. As
part of the reorganization of the Nuveen New York Tax-Free Money Market Fund,
the Service Plan series, the Distribution Plan series and the Institutional
series were consolidated into New York.

Municipal is an open-end, diversified management company incorporated as a
Maryland corporation on July 6, 1982. California and New York are each a series
of the Nuveen Money Market Trust, an open-end management series investment
company organized as a Massachusetts business trust on January 15, 1999.

Each Fund invests substantially all of its assets in a diversified portfolio of
high quality, tax-exempt money market instruments for current income, the
stability of principal, and the maintenance of liquidity.

Each Fund issues its own shares at net asset value, which the Fund will seek to
maintain at $1.00 per share, without a sales charge.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation
Each Fund invests in short-term municipal securities maturing within one year
from the date of acquisition. Securities with a maturity of more than one year
in all cases have variable rate and demand features qualifying them as short-
term securities and are valued at amortized cost. On a dollar-weighted basis,
the average maturity of all such securities must be 90 days or less (at August
31, 2000, the dollar-weighted average life was 35.42 days for Municipal, 33.63
days for California, and 31.98 days for New York).

Securities Transactions
Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
August 31, 2000, Municipal had an outstanding when-issued purchase commitment of
$3,511,690. There were no such outstanding purchase commitments in either
California or New York.

Investment Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts.

Dividends and Distributions to Shareholders
Tax-exempt net investment income is declared as a dividend to shareholders of
record as of the close of each business day and payment is made or reinvestment
is credited to shareholder accounts after month-end. Net realized capital gains
from investment transactions and/or net ordinary taxable income, if any, are
declared and distributed to shareholders annually. Furthermore, capital gains
are distributed only to the extent they exceed available capital loss
carryforwards.

Income Taxes
Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to distribute all of its tax-exempt net investment income, taxable
ordinary income and/or net realized capital gains from investment transactions,
if any, and to otherwise comply with the requirements of Subchapter M of the
Internal Revenue Code applicable to regulated investment companies. Therefore,
no federal income tax provision is required. Furthermore, each Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal income tax and designated state income taxes for
the California and New York Funds, to retain such tax-exempt status when
distributed to the shareholders of the Funds. Net ordinary taxable income and
net realized capital gain distributions, if any, are subject to federal
taxation.

Notes to Financial Statements (Unaudited) (continued)

12b-1 Plan
Each Fund pays a fee to reimburse Nuveen Investments ("Nuveen"), a wholly owned
subsidiary of The John Nuveen Company, the Funds' principal underwriter and
distributor, for compensating authorized dealers of record, including Nuveen,
for providing ongoing services to the Fund or its shareholders. Nuveen may pay
additional amounts to such firms from its own resources at its discretion, and
may retain any portion of the 12b-1 fees not paid to such firms.

Insurance Commitments
The Funds have purchased liability insurance to protect against a decline in the
value of securities held in the Funds' portfolio caused by the default of
securities owned by the Funds. The insurance covers substantially all of the
Funds' investments except U.S. Government securities. The maximum total coverage
for all Nuveen money market funds is $50 million, with certain deductibles for
each loss. The Funds pay the policy premiums. Coverage under the policy is
subject to certain conditions and may not be renewable upon expiration. While
the policy is intended to provide some protection against credit risk and to
help the Funds maintain a constant price per share of $1.00, there is no
guarantee that the insurance will do so.

Derivative Financial Instruments
The Funds may invest in transactions in certain derivative financial
instruments, including futures, forward, swap and option contracts, and other
financial instruments with similar characteristics. Although the Funds are
authorized to invest in such financial instruments, and may do so in the future,
they did not make any such investments during the six months ended August 31,
2000.

Custodian Fee Credit
Each Fund has an agreement with the custodian bank whereby certain custodian
fees and expenses are reduced by credits earned on each Fund's cash on deposit
with the bank. Such deposit arrangements are an alternative to overnight
investments.

Use of Estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

2. Securities Transactions
Purchases and sales (including maturities) of investments in short-term
municipal securities during the six months ended August 31, 2000, were as
follows:
