PAINEWEBBER MONEY MARKET FUND SEMIANNUAL REPORT
October 16, 2000
Dear Shareholder,
We are pleased to present you with the semiannual report for PaineWebber Money
Market Fund (the "Fund") for the six-month period ended August 31, 2000.
MARKET REVIEW
The six-month period ended August 31, 2000 showed a marked change in sentiment
among investors, as fears of inflationary pressures and continued interest rate
increases gave way to guarded optimism that rates would remain stable at least
through the presidential election. The Federal Reserve (the "Fed") raised
short-term interest rates twice, once in March and then in mid-May, resulting in
the Fed Funds rate rising from 5.25% to 6.50%. (The Fed Funds rate is the rate
the Fed charges for overnight loans.) Although the Fed warned that future
increases in 2000 were not out of the question if economic growth didn't slow to
a sustainable pace, fears subsided as the economy finally began to show concrete
proof that it was indeed cooling off.
Through May, yields on fixed income securities were at their highest points
in years, creating difficulty for both bond and money market funds. Money market
funds fared better than other segments of the market, however, because of their
concentration on safety and liquidity.
Finally, as the bond market began to emerge from these difficult conditions
in late spring, yields on the 30-year Treasury began to recover, as the Treasury
began buying back shorter-term debt. The Fed opted to remain neutral at its
August meeting, keeping interest rates where they were.

PORTFOLIO HIGHLIGHTS
During the period, the Fund had a weighted average maturity below that of
its peer group, helping the Fund to weather the difficult market conditions.
Even with some positive signs that interest rates had stabilized, we continued
to monitor general economic uncertainty, especially in light of unpredictable
oil prices. We continued to emphasize quality debt instruments among our
holdings.

OUTLOOK
While the prospects for a soft landing seem more likely now than six months
ago, we cannot ignore potentially troubling aspects of the economy that could
short-circuit that landing and prompt the Federal Reserve to again raise rates.
These signs, including a revision upwards of second quarter gross domestic
product (GDP) and the effect of oil prices on inflation, could be small bumps in
the road to slower growth, but we will continue to monitor events carefully.
Barring major inflationary pressures, we expect that interest rates will remain
stable through the fall presidential election.

Organization and Significant Accounting Policies
PaineWebber Master Series, Inc. ("Master Series") was incorporated in Maryland
on October 29, 1985 and is registered with the Securities and Exchange
Commission under the Investment Company Act of 1940, as amended, as an open-
end, diversified series investment company which currently offers two series of
shares: PaineWebber Money Market Fund ("Fund") and PaineWebber Balanced Fund.
The financial statements for PaineWebber Balanced Fund are not included herein.
The Fund currently offers Class A, Class B and Class C shares. Each class rep-
resents interests in the same assets of the Fund and the classes are identical
except for differences in their sales charge structure, ongoing service and
distribution charges and certain transfer agency and related services expenses.
In addition, Class B shares automatically convert to Class A shares approxi-
mately six years after initial issuance. All classes of shares have equal vot-
ing privileges, except that each class has exclusive voting rights with respect
to its service and/or distribution plan. All classes of shares may be obtained
only through an exchange of shares of the corresponding class of other
PaineWebber mutual funds.
The preparation of financial statements in accordance with generally accepted
accounting principles requires Fund management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from those estimates. The following is
a summary of significant accounting policies:
Valuation and Accounting for Investments--Investments are valued at amortized
cost which approximates market value. Investment transactions are recorded on
the trade date. Realized gains and losses from investment transactions are cal-
culated using the identified cost method. Interest income is recorded on an ac-
crual basis. Premiums are amortized and discounts are accreted as adjustments
to interest income and the identified cost of investments.
Repurchase Agreements--The Fund's custodian takes possession of the collateral
pledged for investments in repurchase agreements. The underlying collateral is
valued daily on a mark-to-market basis to ensure that the value, including ac-
crued interest, is at least equal to the repurchase price. In the event of de-
fault of the obligation to repurchase, the Fund has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligation. Under cer-
tain circumstances, in the event of default or bankruptcy by the other party to
the agreement, realization and/or retention of the collateral may be subject to
legal proceedings. The Fund may participate in joint repurchase agreement
transactions with other funds managed by Mitchell Hutchins Asset Management
Inc. ("Mitchell Hutchins"), an asset management subsidiary of PaineWebber In-
corporated ("PaineWebber") a wholly owned subsidiary of Paine Webber Group Inc.
("PW Group") and investment adviser and administrator of the Fund.
Net Investment Income and Investment Transactions--Income and expenses (ex-
cluding class-specific expenses) are allocated proportionately to each class of
shares based upon the relative net asset value of dividend-eligible shares of
each class at the beginning of the day (after adjusting for current capital
share activity of the respective classes). Realized gains and losses are allo-
cated proportionately to each class of shares based upon the relative value of
shares outstanding at the beginning of the day (after adjusting for current
capital share activity of the respective classes). Class-specific expenses are
charged directly to the applicable class of shares.
Dividends and Distributions--Dividends and distributions to shareholders are
recorded on the ex-dividend date. Dividends and distributions are determined in
accordance with federal income tax regulations, which may differ from generally
accepted accounting principles. These "book/tax" differences are either
considered temporary or permanent in nature. To the extent these differences
are permanent in nature, such amounts are reclassified within the capital
accounts based on their federal tax-basis treatment; temporary differences do
not require reclassification.

Concentration of Risk
The ability of the issuers of the debt securities held by the Fund to meet
their obligations may be affected by economic developments, including those
particular to a specific industry or region.
Investment Adviser and Administrator
The Board of Directors of Master Series has approved an Investment Advisory
and Administration Contract ("Advisory Contract") with Mitchell Hutchins, under
which Mitchell Hutchins serves as investment adviser and administrator of the
Fund. In accordance with the Advisory Contract, the Fund pays Mitchell Hutchins
an investment advisory and administration fee, which is accrued daily and paid
monthly, at the annual rate of 0.50% of the Fund's average daily net assets. At
August 31, 2000, the Fund owed Mitchell Hutchins $28,014 for investment advi-
sory and administration fees.
On July 12, 2000, PW Group and UBS AG ("UBS") announced that they had entered
into an agreement and plan of merger under which PW Group will merge into a
wholly owned subsidiary of UBS. If all required approvals are obtained and the
required conditions are satisfied, PW Group and UBS expect to complete the
transaction in the fourth quarter of 2000. UBS, with headquarters in Zurich,
Switzerland, is an internationally diversified organization with operations in
many areas of the financial services industry.
Distribution Plans
Mitchell Hutchins is the distributor of the Fund's shares and has appointed
PaineWebber as the exclusive dealer for the sale of those shares. Under sepa-
rate plans of service and/or distribution pertaining to Class A, Class B and
Class C shares, the Fund pays Mitchell Hutchins monthly service fees at the an-
nual rate of 0.25% of the average daily net assets of each class of shares and
monthly distribution fees at an annual rate of 0.50% of the average daily net
assets of Class B and Class C shares. At August 31, 2000 the Fund owed Mitchell
Hutchins $31,106 in service and distribution fees.
Mitchell Hutchins also receives the proceeds of the contingent deferred sales
charges paid upon certain redemptions of Class A, Class B and Class C shares.
Mitchell Hutchins has informed the Fund that for the six months ended August
31, 2000, it earned $173,015 in sales charges.
Transfer Agency and Related Services Fees
PaineWebber provides transfer agency related services to the Fund pursuant to
a delegation of authority from PFPC, Inc., the Funds' transfer agent, and is
compensated for these services by PFPC, Inc., not the Fund. For the six months
ended August 31, 2000, PaineWebber received from PFPC, Inc., not the Fund, ap-
proximately 51% of the total transfer agency and related service fees collected
by PFPC, Inc. from the Fund.
Money Market Fund Insurance Bond
Effective September 30, 1999, the Fund obtained an insurance bond that pro-
vides limited coverage for certain loss events involving certain money market
instruments held by the Fund. These loss events include non-payment of princi-
pal or interest or a bankruptcy or insolvency of the issuer or credit enhance-
ment provider (if any). The insurance bond provides for coverage up to $200
million for a number of funds with a deductible of 10 basis points (0.10%) of
the total assets of the Fund for First Tier Securities and 50 basis points
(0.50%) of the total assets of the Fund for Second Tier Securities, in each
case determined as of the close of business on the first business day prior to
the loss event. In the event of a loss covered under the insurance bond, the
Fund would expect to retain the security in its portfolio, rather than having
to sell it at its current market value, until the date of payment of the loss,
which is generally no later than the maturity of the security. 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. For the period September 30, 1999 to August 31, 2000, the
Fund did not use this insurance bond.

Federal Tax Status
The Fund intends to distribute substantially all of its taxable income and to
comply with the other requirements of the Internal Revenue Code applicable to
regulated investment companies. Accordingly, no provisions for federal income
taxes is required. In addition, by distributing during each calendar year
substantially all of its net investment income, capital gains and certain other
amounts, if any, the Fund intends not to be subject to a federal excise tax.
At February 29, 2000, the Fund had a net capital loss carryforward of $608
which will expire by February 28, 2008. To the extent such losses are used as
provided in the regulations, to offset future net realized capital gains, it is
probable these gains will not be distributed.

shares on the first day of each period reported, reinvestment of all
dividends and other distributions at net asset value on the payable dates,
and a sale at net asset value on the last day of each period reported. The
figures do not include any applicable sales charges; results for each class
would be lower if they were included. Total investment return for periods
of less than one year has not been annualized.
