MARKET REVIEW
--------------------------------------------------------------------------------

[GRAPHIC OMITTED]

     The fiscal year ended October 31, 2000 started with a positive economic
backdrop for most of the world's developed economies. As the year progressed,
however, higher commodity prices, particularly oil prices, generated a modest
increase in inflation. As a result, central banks in many developed countries
raised interest rates in an effort to keep inflation from accelerating.

     During the second half of the fiscal year, higher oil prices and interest
rates began to take their toll on economic growth in many areas of the world. In
the United States, the pace of economic growth slowed significantly. The U.S.
unemployment rate rose slightly and consumer spending weakened. Business
purchases declined to their lowest level since the emerging market crisis of
1998.

     In many parts of Europe and the United Kingdom, business sentiment
indicators declined from the high levels reached earlier in the fiscal year.
Nevertheless, they remained above their long-term averages. The economic
downturn in Europe was more limited than in the United States. During the
period, the euro, much of Europe's single currency, continued to decline against
the U.S. dollar and the yen.

     Even though consumer spending continued to be weak, economic data in Japan
indicated stronger economic growth. Much of the upturn in economic growth was
attributed to increased business investment, especially in the high technology
industry. During the period, Japan's central bank reversed its zero
interest-rate policy and boosted short-term interest rates by 0.25%.

PORTFOLIO REVIEW
--------------------------------------------------------------------------------

[GRAPHIC OMITTED]

     During the period, the Fund outperformed its benchmark. Following a
difficult year, there were two major investment decisions affecting the Fund's
performance. The first was our overweight position in European currencies
(including both the euro and non-euro currencies of Sweden and Norway) which
underperformed the U.S. dollar and had a negative impact on the relative
performance of the Fund. On the positive side, our

<PAGE>

PAINEWEBBER GLOBAL INCOME FUND                                     ANNUAL REPORT

substantial underweight position in Japanese bonds, which were among the worst
performing bond markets in local currency terms, added value to the portfolio.

     At the end of the fiscal period, the Fund's largest regional allocation was
to Europe, including the United Kingdom. European investments accounted for
38.1%* of net assets. In Europe, yield curves flattened as markets continued to
factor in expected higher interest rates in response to the weakness of the
euro.

     The Fund's second- largest regional allocation was to the United States at
32.7%.* The U.S. portion of the Fund was invested in U.S. Treasury and corporate
bonds, areas that performed relatively well. As signs of an economic slowdown
became increasingly apparent, yields on intermediate-term bonds declined. In
contrast, yields on short-term and long-term bonds rose.

     The Fund's commitment to Japan was 8.8%.* In Japan, yields on short-,
intermediate-, and long-term bonds rose as a result of the Bank of Japan's tight
monetary policy.

     Rising oil prices and a more favorable U.S. interest rate environment were
positive for emerging market debt. Relatively stable U.S. interest rates and
higher oil prices generally favor emerging market sovereign credits. Oil
exporters such as Mexico and Malaysia benefited from higher export revenues. In
contrast, the performance of South Korea's fixed-income securities was weakened
by its dependence on energy imports. At 3.1%,* Mexico accounted for the largest
allocation to emerging markets. Malaysia followed with a 2.3%* allocation.

OUTLOOK
--------------------------------------------------------------------------------

[GRAPHIC OMITTED]

     Although the U.S. Federal Reserve Board (the "Fed") took no action on
interest rates for several months, it maintained its tightening bias. Going
forward, we believe the Fed will lower short-term interest rates, as the pace of
economic growth continues to slow.

     We find Europe the most attractive market due to its strong fundamentals
and increasing level of corporate restructuring. We therefore hold long duration
positions in many of these bond markets including both euro and non-euro markets
including Denmark and Norway.

     We also find the Japanese bond market the least attractive and hold a large
underweight position versus the benchmark due primarily to the massive amounts
of government debt which are needed to pay for the government's efforts to
stimulate growth.

PROPOSED MERGER AND NEW FUND MANAGEMENT
--------------------------------------------------------------------------------

     On October 6, 2000, the Fund's board of trustees unanimously approved the
submission to shareholders of the merger of the PaineWebber Global Income Fund

     On October 6, 2000, the board of trustees for the Fund approved the
termination of the then existing Investment Advisory and Administration Contract
with Mitchell Hutchins and approved new interim investment management
arrangements that became effective on October 10, 2000, including new interim
sub-advisory contracts with Rogge Global Partners plc and Fischer Francis Trees
& Watts, Inc. and its affiliates, which assumed day-to-day portfolio management
responsibilities for the Fund effective October 10, 2000.

     More information about the proposed merger for the Fund, and new investment

NOTES TO FINANCIAL STATEMENTS

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     PaineWebber Investment Series ("Trust") was organized under Massachusetts
law by a Declaration of Trust dated December 22, 1986 and is registered with the
Securities and Exchange Commission under the Investment Company Act of 1940, as
amended, as a non-diversified open-end management investment company. The Trust
currently has one series, PaineWebber Global Income Fund (the "Fund"). The
Fund's primary investment objective is high current income consistent with
prudent investment risk; capital appreciation is a secondary objective.

     Currently, the Fund offers Class A, Class B, Class C and Class Y shares.
Each class represents interests in the same assets of the Fund, and the classes
are identical except for differences in their sales charge structure, ongoing
service and/or distribution charges, if any, and certain transfer agency and
related expenses. In addition, Class B shares and all corresponding reinvested
dividend shares automatically convert to Class A shares approximately six years
after initial issuance. All classes of shares have equal rights as to voting
privileges except that Class A, Class B and Class C shares each have exclusive
voting rights with respect to their service and/or distribution plan. Class Y
shares have no service or distribution plan.

     The preparation of financial statements in accordance with accounting
principles generally accepted in the United States of America 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 of Investments-The Fund calculates its net asset value based on
the current market value, when available, for its portfolio securities. The Fund
normally obtains market values for its securities from independent pricing
sources. Independent pricing sources may use last sale prices, current market
quotations or valuations from computerized "matrix" systems that derive values
based on comparable securities. Securities traded in the over-the-counter
("OTC") market and listed on The Nasdaq Stock Market, Inc. ("Nasdaq") normally
are valued at the last sale price on Nasdaq prior to valuation. Other OTC
securities are valued at the last bid price available prior to valuation.
Securities which are listed on U.S. and foreign stock exchanges normally are
valued at the last sale price on the day the securities are valued or, lacking
any sales on such day, at the last available bid price. In cases where
securities are traded on more than one exchange, the securities are valued on
the exchange designated as the primary market by Mitchell Hutchins Asset
Management Inc. ("Mitchell Hutchins"), the investment manager and administrator
of the Fund, or by the Fund's sub-advisers. Mitchell Hutchins is a wholly owned
asset management subsidiary of PaineWebber Incorporated ("PaineWebber"), which
is an indirect wholly owned subsidiary of UBS AG. If a market value is not
available from an independent pricing source for a particular security, that
security is valued at fair value as determined in good faith by or under the
direction of the Trust's board of trustees (the "board"). The amortized cost
method of valuation, which approximates market value, generally is used to value
short-term debt instruments with sixty days or less remaining to maturity,
unless the board determines that this does not represent fair value. All
investments quoted in foreign currencies will be valued daily in U.S. dollars on
the basis of the foreign currency exchange rates prevailing at the time such
valuation is determined by the Fund's custodian.

     Foreign currency exchange rates are generally determined prior to the close
of regular trading on the New York Stock Exchange ("NYSE"). Occasionally events
affecting the value of foreign investments and such exchange rates occur between
the time at which they are determined and the close of the NYSE, which will not
be reflected in the computation of the Fund's net asset value. If events
materially affecting the value of such securities or currency exchange rates
during such time period occur, the securities will be valued at their fair value
as determined in good faith by or under the direction of the board.

NOTES TO FINANCIAL STATEMENTS

     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 accrued interest, is at least equal to the repurchase price. In the
event of default of the obligation to repurchase, the Fund has the right to
liquidate the collateral and apply the proceeds in satisfaction of the
obligation. Under certain 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 occasionally
participates in joint repurchase agreement transactions with other funds managed
by Mitchell Hutchins.

     Investment Transactions and Investment Income-Investment transactions are
recorded on the trade date. Realized gains and losses from investments and
foreign exchange transactions are calculated using the identified cost method.
Interest income is recorded on an accrual basis. Discounts are accreted as
adjustments to interest income and the identified cost of investments.

     Income, expenses (excluding class-specific expenses) and
realized/unrealized gains/losses are allocated proportionately to each class of
shares based upon the relative net asset value of outstanding shares (or the
value of dividend-eligible shares, as appropriate) of each class 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.

     Foreign Currency Translation-The books and records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis: (1) market value of investment securities, other
assets and liabilities-at the exchange rates prevailing at the end of the
period; and (2) purchases and sales of investment securities, income and
expenses-at the rates of exchange prevailing on the respective dates of such
transactions.

     Although the net assets and the market values of the Fund's securities are
presented at the foreign exchange rates at the end of the period, the Fund does
not generally isolate the effect of fluctuations in foreign exchange rates from
the effect of the changes in market prices of securities. However, the Fund does
isolate the effect of fluctuations in foreign exchange rates when determining
the gain or loss upon the sale or maturity of foreign currency denominated debt
obligations pursuant to federal income tax regulations. Certain foreign exchange
gains and losses included in realized and unrealized gains and losses are
included in or are a reduction of ordinary income in accordance with federal
income tax regulations. Net realized foreign currency gain (loss) is treated as
ordinary income for income tax reporting purposes. Gains/losses from translating
foreign currency denominated assets and liabilities at year-end exchange rates
are included in change in unrealized appreciation/depreciation of other assets
and liabilities denominated in foreign currencies.

     Forward Foreign Currency Contracts-The Fund may enter into forward foreign
currency exchange contracts ("forward contracts") in connection with planned
purchases or sales of securities or to hedge the U.S. dollar value of portfolio
securities denominated in a particular currency. The Fund may also use forward
currency contracts to enhance income.

     The Fund has no specific limitation on the percentage of assets which may
be committed to such contracts. The Fund may enter into forward contracts or
maintain a net exposure to forward contracts only if (1) the consummation of the
contracts would not obligate the Fund to deliver an amount of foreign currency
in excess of the value of the position being hedged by such contracts or (2) the
Fund maintains cash or liquid securities in a segregated account in an amount
not less than the value of its total assets committed to the consummation of the
forward contracts and not covered as provided in (1) above, as marked-to-market
daily.


                                                                              17
<PAGE>


NOTES TO FINANCIAL STATEMENTS

     Risks may arise with respect to entering into forward contracts from the
potential inability of counterparties to meet the terms of their forward
contracts and from unanticipated movements in the value of foreign currencies
relative to the U.S. dollar.

     Fluctuations in the value of forward contracts are recorded for book
purposes as unrealized gains or losses by the Fund. Realized gains and losses
include net gains and losses recognized by the Fund on contracts which have
matured.

     Futures Contracts-Using financial futures contracts involves various market
risks. The maximum amount at risk from the purchase of a futures contract is the
contract value. The Fund primarily uses financial futures contracts for hedging
purposes or to manage the average duration of the Fund. However, imperfect
correlations between futures contracts and the Fund securities being hedged, or
market disruptions, do not normally permit full control of these risks at all
times.

     Upon entering into a financial futures contract, the Fund is required to
pledge to a broker an amount equal to a certain percentage of the contract
amount. This amount is known as the "initial margin." Subsequent payments, known
as "variation margin," are made or received by the Fund each day, depending on
the daily fluctuations in the value of the underlying financial futures
contracts. Such variation margin is recorded for financial statement purposes on
a daily basis as an unrealized gain or loss until the financial futures contract
is closed, at which time the net gain or loss is reclassified to realized.

     Dividends and Distributions-Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of 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

     Investing in securities of foreign issuers and currency transactions may
involve certain considerations and risks not typically associated with
investments in the United States. These risks include revaluation of currencies,
adverse fluctuations in foreign currency values and possible adverse political,
social and economic developments, including those particular to a specific
industry, country or region, which could cause the securities and their markets
to be less liquid and prices more volatile than those of comparable U.S.
companies and U.S. government securities. These risks are greater with respect
to securities of issuers located in emerging market countries in which the Fund
is authorized to invest. The ability of the issuers of debt securities held by
the Fund to meet their obligations may be affected by economic and political
developments particular to a specific industry, country or region.

     At October 31, 2000, the Fund had approximately $23,937,697 in an interest
bearing account with a single institution, Brown Brothers Harriman, the Fund's
custodian.

INVESTMENT  MANAGER AND ADMINISTRATOR, SUB-ADVISORS

     The Trust's board has approved an Interim Investment Management and
Administration Contract ("Advisory Contract") with Mitchell Hutchins, under
which Mitchell Hutchins serves as investment manager and administrator of the
Fund. The Advisory Contract authorizes Mitchell Hutchins to retain one or more
sub-advisers for the management of the Fund's investment portfolio. In
accordance with the Advisory Contract, the Fund pays Mitchell Hutchins an
investment management and administration fee, which is accrued daily and paid
monthly, in accordance with the following schedule:

     The Trust's board approved two Interim Sub-Advisory Contracts - one between
Mitchell Hutchins and Rogge Global Partners plc and the second between Mitchell
Hutchins and Fischer Francis Trees & Watts, Inc. and its affiliates ("FFTW").
Under its Advisory Contract relating to the Fund, Mitchell Hutchins' primary
portfolio management responsibility is to identify appropriate sub-advisers to
manage the Fund's assets and to review and monitor the performance of those
sub-advisers. Mitchell Hutchins has initially allocated the Fund's assets
between Rogge Global Partners and FFTW in approximately equal portions. The
relative values allocated to each sub-adviser may change over time. Mitchell
Hutchins (not the Fund) pays a fee to the sub-advisers.

     At October 31, 2000, the Fund owed Mitchell Hutchins $163,972 in investment
advisory and administration fees. Mitchell Hutchins waived a portion of its
investment advisory and administration fees in connection with the Fund's
investment of cash collateral from security lending in the Mitchell Hutchins
Private Money Market Fund LLC. For the year ended October 31, 2000, Mitchell
Hutchins waived $7,793.

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 separate
plans of service and/or distribution pertaining to the Class A, Class B and
Class C shares, the Fund pays Mitchell Hutchins monthly service fees at the
annual rate of 0.25% of the average daily net assets of Class A, Class B and
Class C shares and monthly distribution fees at the annual rates of 0.75% and
0.50% of the average daily net assets of Class B and Class C shares,
respectively. At October 31, 2000, the Fund owed Mitchell Hutchins $63,191 in
service and distribution fees.

     Mitchell Hutchins also receives the proceeds of the initial sales charges
paid by shareholders upon the purchase of Class A shares and the contingent
deferred sales charge paid by shareholders upon certain redemptions of Class A,
Class B and Class C shares. Mitchell Hutchins has informed the Fund that for the
year ended October 31, 2000, it earned $22,693 in sales charges.


SECURITY LENDING

     The Fund may lend securities up to 331|M/3% of its total assets to
qualified institutions. The loans are secured at all times by cash or U.S.
government securities in an amount at least equal to the market value of the
securities loaned, plus accrued interest, determined on a daily basis and
adjusted accordingly. The Fund will retain record ownership of loaned securities
to exercise certain beneficial rights; however, the Fund may bear the risk of
delay in recovery of, or even loss of rights in, the securities loaned should
the borrower fail financially. The Fund is compensated for the lending of its
securities, which is included in interest income, from interest earned on the
cash or U.S. government securities held as collateral, net of fee rebates paid
to the borrower plus reasonable administrative and custody fees. For the year
ended October 31, 2000, the Fund earned $35,489 as compensation


                                                                              19

BANK LINE OF CREDIT

     The Fund may participate with other funds managed by Mitchell Hutchins in
a $200 million committed credit facility ("Facility") to be utilized for
temporary financing until the settlement of sale or purchase of portfolio
securities, the repurchase or redemption of shares of the Fund at the request
of the shareholders and other temporary or emergency purposes. In connection
therewith, the Fund has agreed to pay a commitment fee, pro rata, based on the
relative asset size of the funds in the Facility. Interest is charged to the
Fund at rates based on prevailing market rates in effect at the time of
borrowings. For the year ended October 31, 2000, the Fund did not borrow under
the Facility.

NOTES TO FINANCIAL STATEMENTS

     For the year ended October 31, 2000, total aggregate purchases and sales
of portfolio securities, excluding short-term securities, were as follows:

  Purchases ........................................       $127,506,019
  Sales ............................................       $169,570,197

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 provision 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 October 31, 2000, the Fund had a capital loss carryforward of
$21,604,858 available as a reduction, to the extent provided in the regulations,
of any future net realized capital gains, which expires as follows: $1,494,819
in 2002, $15,753,815 in 2003 and $4,356,224 in 2008. To the extent that such
losses are used to offset future capital gains, it is probable that the gains so
offset will not be distributed.

     To reflect reclassifications for the Fund arising from permanent "book/tax"
differences for the year ended October 31, 2000, undistributed net investment
income was decreased by $223,142, accumulated net realized losses from
investment transactions were decreased by $11,607,383 and beneficial interest
was decreased by $11,384,241. Permanent "book/tax" differences were primarily
attributable to the foreign currency gains/losses.


                                                                              21

+    Investment advisory functions for this Fund were transferred from Mitchell
     Hutchins Asset Management Inc. to Rogge Global Partners plc and Fischer
     Francis Trees & Watts, Inc. (and affiliates) on October 10, 2000.
(1)  Total investment return is calculated assuming a $10,000 investment on the
     first day of each year reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each year reported. The figures do not
     include any applicable sales charges; results would be lower if they were
     included.
(2)  During the years ended October 31, 2000 and October 31, 1999, Mitchell
     Hutchins waived a portion of its advisory and administration fees. The
     ratios excluding the waiver would be the same since the fee waiver
     represents less than 0.005%.

     Hutchins Asset Management Inc. to Rogge Global Partners plc and Fischer
     Francis Trees & Watts, Inc. (and affiliates) on October 10, 2000.
(1)  Total investment return is calculated assuming a $10,000 investment on the
     first day of each year reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each year reported. The figures do not
     include any applicable program fees; results would be lower if they were
     included.
(2)  During the years ended October 31, 2000 and October 31, 1999, Mitchell
     Hutchins waived a portion of its advisory and administration fees. The
     ratios excluding the waiver would be the same since the fee waiver
     represents less than 0.005%.

PAINEWEBBER GLOBAL INCOME FUND

REPORT OF INDEPENDENT ACCOUNTANTS



To the Shareholders and Trustees of
PaineWebber Investment Series


In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of PaineWebber Global Income Fund (a
series of PaineWebber Investment Series and hereafter referred to as the
"Fund") at October 31, 2000, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended and the financial highlights for each of the periods indicated, in
conformity with accounting principles generally accepted in the United States
of America. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Fund's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with auditing standards generally accepted in the
United States of America, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at October 31, 2000 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

As described in the notes to the financial statements, on October 6, 2000, the
Board of Trustees approved a merger, subject to shareholder approval, whereby
the Fund would be merged into the PACE Global Fixed Income Investments.

TAX INFORMATION (unaudited)


     We are required by Subchapter M of the Internal Revenue Code of 1986, as
amended, to advise you within 60 days of the Fund's fiscal year end (October
31, 2000) as to the federal tax status of distributions received by
shareholders during such fiscal year. Accordingly, we are advising you that the
distributions paid during the fiscal year by the Fund were classified on a per
share basis as follows:

                                                 ------------   ------------   ------------   ------------

   Ordinary Income ...........................   $ 0.1755       $ 0.1454       $ 0.1604       $ 0.1867
   Distribution from paid in capital .........   $ 0.3720       $ 0.3080       $ 0.3411       $ 0.3953
</TABLE>


     Dividends received by tax-exempt recipients (e.g., IRAs and Keoghs) need
not be reported as taxable income. Some retirement trusts (e.g., corporate,
Keogh and 403(b)(7) plans) may need this information for their annual
information reporting.

     Since the Fund's fiscal year is not the calendar year, another
notification will be sent with respect to calendar year 2000. Such
notification, which will reflect the amount to be used by calendar year
taxpayers on their federal income tax returns, will be made in conjunction with
Form 1099 DIV and will be mailed in January 2001. Shareholders are advised to
consult their own tax advisers with respect to the tax consequences of their
investment in the Fund.
