The performance of the other classes will vary from the performance of the class
shown because of differences in sales charges and fees paid by shareholders
investing in different classes.

(****) Life: since commencement of issuance on August 31,1984 for Class A
shares, July 1, 1991 for Class B shares and July 2, 1992 for Class C shares.

The Fund offers Class Y shares to a limited group of eligible investors,
including participants in certain investment programs that are sponsored by
PaineWebber and that may invest in PaineWebber mutual funds, as well as the
trustee of the Painewebber 401(k) Plus Plan (formerly known as PaineWebber
Savings Investment Plan). For the one year and five year periods ended November
30, 1998, and since inception on September 11, 1991 to November 30, 1998, Class
Y shares have produced average annual total returns of 9.41%, 4.94% and 5.94%,
respectively. Class Y shares do not bear initial or contingent deferred sales
charges or ongoing distribution and service fees.

The investment return and the principal value of an investment in the Fund will
fluctuate, so that an investor's shares, when redeemed, may be worth more or
less than their original cost.

The graph depicts the performance of PaineWebber Low Duration U.S. Government
Income Fund versus the Lehman Brothers ARM Index and the Merrill Lynch 1-3 Year
U.S. Treasury Index. It is important to note PaineWebber Low Duration U.S.
Government Income Fund is a professionally managed mutual fund while the indices
are not available for investment and are unmanaged. The comparisons are shown
for illustrative purposes only.

The Fund's performance benchmark has been changed to the Merrill Lynch 1-3 Year
U.S. Treasury Index. The Merrill Lynch 1-3 Year U.S. Treasury Index is a more
widely followed benchmark of short-duration portfolio returns and is believed to
be a more appropriate index for comparison with the Fund's total return
performance. The Fund's prior benchmark, the Lehman Brothers ARM Index, is also
shown in this report's performance graph but will not appear in subsequent
reports.

The graph depicts the performance of PaineWebber Investment Grade Income Fund
Class A versus the Lehman Brothers Corporate Bond Index. It is important to note
the PaineWebber Investment Grade Income Fund is a professionally managed mutual
fund while the index is not available for investment and is unmanaged. The
comparison is shown for illustrative purposes only.


Past performance is no guarantee of future performance.
The performance of the other classes will vary from the performance of the class
shown because of differences in sales charges and fees paid by shareholders
investing in different classes.

The Fund's performance benchmark has been changed to the Credit Suisse First
Boston High Yield Index. The Index is a more widely followed benchmark of high
yield portfolio returns and is believed to be a more appropriate broad-based
index for comparison with the Fund's total return performance. The Fund's prior
benchmark, the Lehman Brothers High Yield Bond Index, is also shown in this
report's performance graph but will not appear in subsequent reports.

Dear Shareholder,

We are pleased to present you with the annual report for the PaineWebber U.S.
Government Income Fund, the PaineWebber Low Duration U.S. Government Income
Fund, the PaineWebber Investment Grade Income Fund and the PaineWebber High
Income Fund for the fiscal year ended November 30, 1998.


MARKET REVIEW
================================================================================

 [GRAPHIC]  "Flight to quality" remained the dominant theme in the bond markets
during the fiscal year ended November 30, 1998, as investors sought the safety
and liquidity of U.S. Treasury securities, especially short- to intermediate-
term debt.

   Turmoil hit the global capital markets in August when Russia devalued its
currency and effectively defaulted on its internal debt. The ensuing sell-off in
the global equity and emerging debt markets spurred the flight to U.S. Treasurys
to an even higher pitch. Return of capital, not return on capital, became the
dominant theme in the markets. All sectors of the bond market suffered as risk
premiums soared. Emerging market debt fared the worst, with the high yield
sector following a distant second. U.S. corporate bonds were hard hit, and
corporations suffered from a market-induced credit crunch.

   The global sell-off continued to disrupt the financial markets in September.
Initial public offerings of stocks and the entire high-yield debt market ground
to a virtual halt. With market conditions so fragile, the Federal Reserve
lowered the Fed Funds rate (the rate for overnight loans) from 5.50% to 5.25%.

   The flight to quality became a "flight to liquidity" as investors swarmed to
"on-the-run" (most recently auctioned) benchmark Treasurys. Barely two weeks
into October, the Fed again lowered the Fed Funds rate and also lowered the
discount rate (the rate commercial banks pay to borrow from the Federal
Reserve). The market took this action as a sign of the Fed's resolve to keep the
economy growing in its effort to avoid a recession. Investors reacted 
positively--the stock market rose and shorter-maturity Treasurys rallied.
Corporate bonds continued to lose ground as they lagged the rally in Treasury
yields.

   The Fed lowered both rates again in November, and several European central
banks followed suit in preparation for the January 1, 1999 debut of the euro
currency. The third rate reduction in as many months boosted corporate bonds and
mortgage-backed securities as market psychology and liquidity improved.
Corporate bonds produced their best monthly return since the inception of the
Lehman indices in 1973, only three months after posting their worst monthly
return.

OUTLOOK

   While the U.S. manufacturing sector has been losing jobs and industrial
production has been flat since Asia began


                                                                               5

ANNUAL REPORT


unraveling in late 1997, the larger economy has proven resilient. As of this
writing, gross domestic product for 1998 is likely to have reached 3.8%, the
same rate as 1996 and 1997. Ironically, the same forces that weakened
manufacturing stimulated demand--by deflating import prices. This immunity to
weakening U.S. exports is likely to be further tested, as widespread weakness in
commodity prices underscores a global economy at risk of recession.

   Consumer spending continues to drive the U.S. economy; the savings rate
recently fell into negative territory. This may be an indication of just how
dependent the U.S. economy is on the strength of the stock market, since the
"wealth effect" of stock gains strongly affects consumers' perceptions of how
much they can afford to spend. If the corporate earnings outlook does not
improve, the wealth effect could dissipate.

   Bond market liquidity has improved, but may worsen again if any of a number
of potential problems arises: a further deterioration of Brazil's financial
condition, weakness in the U.S. stock market or further spread of the Asian
crisis. We expect the U.S. economy to grow more slowly in 1999, with inflation
remaining benign, and do not believe a recession is likely. In this economic
environment we foresee the 30-year Treasury bond trading within a 4.75-5.75%
range.

PERFORMANCE

   The Fund's total return consists of the change in net asset value with
dividends reinvested. For the fiscal year ended November 30, 1998, without
deducting sales charges, Class A shares gained 9.06%, Class B shares gained
8.16%, Class C shares gained 8.50% and Class Y shares gained 9.41%.

   The Fund's total return may be lower for shareowners who purchased or
redeemed Fund shares during the period. After deducting the maximum applicable
sales charges, Class A shares gained 4.72%, Class B shares gained 3.16% and
Class C shares gained 7.75%. Class Y shares are not subject to sales charges.

PORTFOLIO

HIGHLIGHTS

   The Fund began the latter half of its fiscal year overweighted in mortgage-
backed and government agency securities, as we maintained our focus on adding
portfolio value by enhancing yield. At the same time, we emphasized call
protection in an environment of heightened prepayment risk. As the period began
we perceived the Federal Reserve to be on hold, and therefore expected
relatively low volatility in the bond market.

   Instead, market volatility became extreme in August after Russia devalued the
ruble and hedge funds began unwinding their leveraged


                                                                               6

positions. The speed of the financial de-leveraging propelled sector spreads
beyond levels consistent with fundamentals and precluded major allocation
changes to the Fund. The Fund rode out the storm without selling into a down
market, and by fiscal year-end its portfolio had recovered quite well from the
volatility of the August-October period.

   We did make some adjustments to the Fund during the period, increasing agency
notes from 14.7% as of May 31, 1998 to 15.5%,(1) and decreasing Treasurys from
28.5% as of May 31 to 24.7%.

GOING FORWARD

   During November we increased the Fund's exposure to the mortgage sector--we
believe mortgage spreads to Treasurys are extremely attractive despite high
prepayment risks. We think investors have become more credit-risk averse in
reaction to events in the international markets, and we believe the high credit
quality of mortgage securities and their historically low prices will attract
investors to the sector.

PORTFOLIO
HIGHLIGHTS

   In May we anticipated that interest rates would fall, and positioned the Fund
to be more sensitive to interest rate declines than its benchmark (the Merrill
Lynch 1-3 Year Treasury Index) seeking to capture potential returns from such a
fall in rates. In technical terms, we maintained a longer "duration" than the
Index. As rates fell during the second half of the fiscal year, the Fund
benefited to a greater extent than did the Index.

   Although the Fund's duration was properly positioned for the decline in
interest rates, the Fund's sector allocation proved detrimental. The latter part
of the fiscal year was a period of severe illiquidity in the fixed income
markets as investors fled all sectors but U.S. Treasurys. The result was strong
Treasury performance at the expense of just about every other fixed income
sector. The Fund's holdings of mortgage-backed securities did not keep pace with
Treasurys. Since the Index consists entirely of Treasurys, the Fund
underperformed its benchmark.

GOING FORWARD

   We expect the Federal Reserve to continue lowering interest rates in 1999 to
forestall an economic slowdown, and have structured the portfolio accordingly.
We intend to maintain portfolio duration about one-half year above the
benchmark. In anticipation of further economic slowdown, additional Fed easing,
and a steeper yield curve, we have concentrated the portfolio in intermediate
maturities (a "bullet" structure). We continue to believe mortgages are the most
prudent way to enhance portfolio yield without adding undue risk. Since October,
the mortgage market has regained ground. We continue to focus our mortgage
investments in the sectors where prepayment risks are minimal such as discount
coupons and structured collateralized mortgage obligations (CMOs).

PERFORMANCE

   The Fund's total return consists of the change in net asset value with
dividends reinvested. For the fiscal year ended November 30, 1998, without
deducting sales charges, Class A shares gained 6.37%, Class B shares gained
5.56% and Class C shares gained 5.84%. Class Y shares commenced issuance on
February 18, 1998; from commencement through November 30, 1998 Class Y shares
gained 3.51%.

   The Fund's total return may be lower for shareowners who purchased or

sales charges, Class A shares gained 2.14%, Class B shares gained 0.58% and
Class C shares gained 5.09%. Class Y shares are not subject to sales charges.

PORTFOLIO
HIGHLIGHTS

   Corporate bonds began to lag Treasurys in July. Russia's effective default in
August upset bond markets around the world and led to losses in most asset
classes, including the Fund's positions in crossover issues(3) and BBB-rated
corporates. Higher quality corporates posted modest gains but significantly
lagged Treasurys. Corporate bonds did not start to recover until mid October,
when the Federal Reserve surprised the market by cutting interest rates between
its regular meetings.

   During the second half of the fiscal year we raised portfolio credit quality
by reducing the Fund's exposure to crossovers and BB credits, and by increasing
its U.S. Treasury and government agency positions. The Fund's average credit
quality was A+ at the end of the fiscal year, compared to the BBB average of its
Lipper peer group.

   The Fund was hurt during the period by its longer maturity profile. As the
"flight to quality" turned into a "flight to liquidity," shorter-maturity
Treasurys made rapid gains while longer

maturity debt of all classes lagged the front end of the yield curve. The Fund's
overweighting in longer maturities was driven mainly by the relatively steep
corporate credit curves in the market. (A steep curve means the longer the
maturity, the higher the yield.) Many of the Fund's longer-term holdings are
call-protected, high-coupon bonds, which can be hard to find in the marketplace.
We felt that the flight-to-liquidity trade was difficult to time and temporary,
and that the steep curves would flatten over time, so we maintained the Fund's
positions.

   During the second half of the fiscal year the Fund raised its allocation to
cable/media (14.3% from 9.7% at the end of May), still its largest industry
weighting.(1) The sector has benefited from its predictable cash flows and
defensive nature. Noteworthy positions include News America Holdings (3.9%),
which sold 18.7% ($2.8 billion) of its Fox Entertainment Group in an initial
public offering and reiterated its commitment to pay down debt. Tele-
Communications Inc. (TCI) (4.4%) is to be acquired by AT&T Corp. in a stock-for-
stock swap. The Fund holds subordinated 9.65% bonds due 3/31/2027, which we
think are likely to receive a credit upgrade after the acquisition.

GOING FORWARD

   We believe the credit cycle has matured to the point where industry
allocation and security selection are likely to be primary drivers of
performance. The Fund generally had a more defensive orientation over the last
year, emphasizing higher quality and domestic issuers. We intend to continue the
emphasis on stable industries with favorable risk/return characteristics, and to
make opportunistic use of crossovers and the upper tier of the high-yield market
as permitted.

PERFORMANCE

   The Fund's total return consists of the change in net asset value with
dividends reinvested. For the fiscal year ended November 30, 1998, without
deducting sales charges, Class A shares lost 4.46%, Class B shares lost 5.32%
and Class C shares lost 4.92%. Class Y shares commenced issuance on February 20,
1998; from commencement through November 30, 1998, Class Y shares lost 8.43%.

   The Fund's total return may be lower for shareowners who purchased or
redeemed Fund shares during the period. After deducting the maximum applicable
sales charges, Class A shares lost 8.30%, Class B shares lost 9.68% and Class C
shares lost 5.58%. Class Y shares are not subject to sales charges.

HIGHLIGHTS

   The Fund's underperformance for the fiscal year may be attributed to its

and higher-quality, dollar-denominated emerging market issues. During its fiscal
year, the Fund was overweighted in both of these sub-sectors of the high-yield
market, which both lagged the overall market.

   Historically, smaller domestic issues (less than $200 million) generally have
shown lower volatility than larger issues, and the Fund has emphasized them to
limit portfolio volatility. While we believe that smaller issues will improve,
we think their higher volatility during the last fiscal year may reflect
structural changes in the market rather than short-term deviations from the
historical norm. Institutional investors--who tend to buy larger issues--are
exerting more influence on the high-yield market and their influence seems
likely to grow. We have reduced the Fund's exposure to smaller issues and have
begun redeploying some of the assets into larger issues. We expect to continue
this redeployment going forward.

   We do not think the emerging markets will recover in the next six to twelve
months, and have reduced the Fund's exposure from 6.0% at the end of May to 2.1%
at the end of November.(1) We also reduced its energy holdings from 8.4% in May
to 4.3%.(1) Within the Fund's energy exposure we sold companies with Gulf of
Mexico operations in favor of companies with North Sea operations. Because North
Sea operations are more difficult than Gulf operations, they are more costly and
entail longer-term commitments. These longer-term commitments tend to reduce the
yield volatility of North Sea operators' debt.

   We increased the Fund's exposure to communications (16.2% for the Fund vs.
15.3% for the CSFB High Yield Index, the Fund's new performance benchmark).(1)
The Fund's greatest concentrations in this sector are in European long distance
companies and "asset-rich" U.S. carriers, i.e., companies that own the fiber-
optic lines. New acquisitions over the latter half of the fiscal year included
Qwest Communications International (0.3%) and Metromedia Fiber Network (0.6%).
The Fund continues to hold Viatel (2.4%), a European long distance carrier and
fiber-optic line owner.

   Other changes to the Fund included an increase in its cable weighting from
6.4% in May to 7.8% in November and a reduction of its media exposure from 7.7%
in May to 5.8%.(1)

   We expect the high-yield sector to improve over the next six months. Spreads
to Treasury securities are still much wider than they were at the start of 1998,
and well above their historical average of 491 basis points. (A basis point
equals 1/100th of one percent.) We think spreads could tighten over the next few
months on the strength of new year buying as investors rebalance portfolios.

   The default rate for high-yield debt is likely to increase to 2-4% from about
1% currently. Since the risk premium for smaller issues has increased, security
selection will become even more important than it was in 1998. The recent rally
in the high-yield market has focused on an extremely narrow subset of only 77
larger issues out of more than 2,500. We look for the rally to broaden in 1999
and include the smaller issues.

Notes to Financial Statements
Organization and Significant Accounting Policies
 PaineWebber Managed Investments Trust (the "Trust") was organized under Massa-
chusetts law by a Declaration of Trust dated November 21, 1986 and is regis-
tered with the Securities and Exchange Commission under the Investment Company
Act of 1940, as amended, as an open-end, diversified investment company. The
Trust is a series mutual fund with seven funds: PaineWebber U.S. Government In-
come Fund ("U.S. Government Income Fund"), PaineWebber Low Duration U.S. Gov-
ernment Income Fund ("Low Duration U.S. Government Income Fund"), PaineWebber
Investment Grade Income Fund ("Investment Grade Income Fund"), PaineWebber High
Income Fund ("High Income Fund") (collectively, the "Funds"), PaineWebber Util-
ity Income Fund, PaineWebber Asia Pacific Growth Fund and PaineWebber Tax-Man-
aged Equity Fund. The financial statements for PaineWebber Utility Income Fund,
PaineWebber Asia Pacific Growth Fund and PaineWebber Tax-Managed Equity Fund
are not included herein.
 Costs incurred by Low Duration U.S. Government Income Fund in connection with
its organization were fully deferred as of November 30, 1998 using the
straight-line method over the sixty months from the commencement of operations.
 Currently, each Fund offers Class A, Class B, Class C and Class Y shares. Each
class represents interests in the same assets of the applicable Fund, and the
classes are identical except for differences in their sales charge structures,
ongoing service and distribution charges and certain transfer agency expenses.
In addition, Class B shares and all corresponding reinvested dividend shares
automatically convert to Class A shares approximately six years after issuance.
All classes of shares have equal voting privileges except that each class has
exclusive voting rights with respect to its service and/or distribution plan.
Class Y shares have no service or distribution plan.
 The preparation of financial statements in accordance with generally accepted
accounting principles requires Fund management to make estimates and assump-
tions that affect the reported amounts and disclosures in the financial state-
ments. Actual results could differ from those estimates. The following is a
summary of significant accounting policies:
 Valuation of Investments--Where market quotations are readily available, port-
folio securities are valued thereon, provided such quotations adequately re-
flect the fair value of the securities, in the judgment of Mitchell Hutchins
Asset Management Inc. ("Mitchell Hutchins"), a wholly owned asset management
subsidiary of PaineWebber Incorporated ("PaineWebber") and investment adviser
and administrator of the Funds. When market quotations are not readily avail-
able, securities are valued based upon appraisals derived from information con-
cerning those securities or similar securities received from recognized dealers
in those securities. All other securities are valued at fair value as deter-
mined 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 mar-
ket 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.
 Repurchase Agreements--The Funds' 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, each 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. Each of the Funds occasionally participates in joint repur-
chase agreement transactions with other funds managed by Mitchell Hutchins.
 Investment Transactions and Investment Income--Investment transactions are re-
corded on the trade date. Realized gains and losses from investment transac-
tions are calculated using the identified cost method. Interest income is re-
corded
 
42

Notes to Financial Statements
on an accrual basis. Dividend income is recorded on the ex-dividend date. Dis-
counts are accreted and premiums are amortized (with the exception of U.S. Gov-
ernment Income Fund) 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 (af-
ter adjusting for current capital share activity of the respective classes).
Class-specific expenses are charged directly to the applicable class of shares.
 Dollar Rolls--Low Duration U.S. Government Income Fund and U.S. Government In-
come Fund may enter into transactions in which these Funds sell securities for
delivery in the current month and simultaneously contracts to repurchase sub-
stantially similar (same type, coupon and maturity) securities on a specified
future date (the "roll period"). During the roll period the Funds forego prin-
cipal and interest paid on the securities. The Funds are compensated by the in-
terest earned on the cash proceeds of the initial sale and by fee income or a
lower repurchase price.
 Futures Contracts--Upon entering into a financial futures contract, the Fund
is required to pledge to a broker an amount of cash and/or U.S. Government se-
curities equal to a certain percentage of the contract amount. This amount is
known as the "initial margin." Subsequent payments, known as "variation mar-
gin," are made or received by the Fund each day, depending on the daily fluctu-
ations in the value of the underlying financial futures contracts. Such varia-
tion margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss until the financial futures contract is closed, at
which time the net gain or loss is reclassified to realized.
 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 Funds (except High Income Fund) primarily use financial futures contracts
for hedging or to manage the average duration of the Fund's portfolio. However,
imperfect correlations between futures contracts and the portfolio securities
being hedged, or market disruptions, do not normally permit full control of
these risks at all times.
 Option Writing--When the Fund writes a call or a put option, an amount equal
to the premium received by the Fund is included in the Fund's Statement of As-
sets and Liabilities as an asset and as an equivalent liability. The amount of
the liability is subsequently marked-to-market to reflect the current market
value of the option written. If an option which the Fund has written either ex-
pires on its stipulated expiration date or the Fund enters into a closing pur-
chase transaction, the Fund realizes a gain (or loss if the cost of a closing
purchase transaction exceeds the premium received when the option was written)
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is extinguished. If a call option which
the Fund has written is exercised, the Fund realizes a capital gain or loss
(long-term or short-term, depending on the holding period of the underlying se-
curity) from the sale of the underlying security and the proceeds from the sale
are increased by the premium originally received. If a put option which a Fund
has written is exercised, the amount of the premium originally received reduces
the cost of the security which the Fund purchases upon exercise of the option.
The U.S. Government Income Fund primarily uses written options for the enhance-
ment of income to the Funds.
 Reverse Repurchase Agreements--Each of the Funds may enter into reverse repur-
chase agreements with qualified third party broker-dealers as determined by,
and under the direction of, the board. Interest on the value of reverse repur-
chase agreements issued and outstanding is based upon competitive market rates
at the time of issuance. At the time the Fund
 
                                                                              43

Notes to Financial Statements
enters into a reverse repurchase agreement, it establishes and maintains a seg-
regated account with the Fund's custodian containing liquid securities having a
value not less than the repurchase price, including accrued interest, of the
reverse repurchase agreement.
 For the year ended November 30, 1998, the Low Duration U.S. Government Income
Fund is the only Fund which engaged in reverse repurchase agreements. The aver-
age monthly balance of reverse repurchase agreements outstanding during the
year ended November 30, 1998 was $3,751,201 at a weighted average interest rate
of 5.62%.
 Dividends and Distributions--Dividends and distributions to shareholders are
recorded on the ex-dividend date. Dividends from net investment income and dis-
tributions from realized capital gains are determined in accordance with fed-
eral 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 fed-
eral tax-basis treatment; temporary differences do not require reclassifica-
tion.
Concentration of Risk
 The ability of the issuers of the debt securities including mortgage- and as-
set-backed securities held by the Funds to meet their obligations may be af-
fected by economic developments, including those particular to a specific in-
dustry or region. Mortgage- and asset-backed securities may decrease in value
as a result of increases in interest rates and may benefit less than other
fixed-income securities from declining interest rates because of the risk of
prepayments.
Written Option Activity
 Transactions in options written for the year ended November 30, 1998 were as
follows:

serves as investment adviser and administrator of the Funds. In accordance with
the Advisory Contract, each Fund pays Mitchell Hutchins an investment advisory

Notes to Financial Statements
Mitchell Hutchins (not the Fund) pays PIMCO a fee, computed daily and payable
monthly, in an amount equal to one-half of the advisory fee received by Mitch-
ell Hutchins from the Fund.
Distribution Plans
 Mitchell Hutchins is the distributor of each 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 the Class A, Class B
and Class C shares, each 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 rate of 0.75%
and 0.50% of the average daily net assets of Class B and Class C shares, re-
spectively. At November 30, 1998, U.S. Government Income Fund, Low Duration
U.S. Government Income Fund, Investment Grade Income Fund and High Income Fund
owed Mitchell Hutchins $92,188, $67,838, $97,178 and $251,368, respectively, in

 Mitchell Hutchins also receives the proceeds of the initial sales charges paid
by the shareholders upon the purchase of Class A shares and the contingent de-
ferred sales charges paid by the shareholders upon certain redemptions of Class
A, Class B and Class C shares. Mitchell Hutchins has informed each Fund that
for the year ended November 30, 1998, it earned $46,733, $76,476, $249,808 and
$1,137,630 in sales charges for the U.S. Government Income Fund, Low Duration
U.S. Government Income Fund, Investment Grade Income Fund and High Income Fund,
respectively.
Security Lending
 Each Fund may lend securities up to 33 1/3% of its total assets to qualified
institutions. The loans are secured at all times by cash or U.S. government se-
curities in an amount at least equal to the market value of the securities
loaned, plus accrued interest, determined on a daily basis and adjusted accord-
ingly. Each Fund will regain record ownership of loaned securities to exercise
certain beneficial rights; however, each Fund may bear the risk of delay in re-
covery of, or even loss of rights in, the securities loaned should the borrower
fail financially. Each Fund receives compensation, which is included in inter-
est income, for lending its securities from interest earned on the cash or U.S.
government securities held as collateral, net of fee rebates paid to the bor-
rower plus reasonable administrative and custody fees. Each Fund's lending
agent is PaineWebber, who received compensation for the year ended November 30,
1998 from the following Funds:

Investment Grade Income Fund earned compensation of $9,098 and $71,790 net of
fees, rebates and expenses, from securities lending transactions. At November
30, 1998 there were no securities on loan from the Funds.
Bank Line of Credit
 Each Fund may participate with other funds managed by Mitchell Hutchins in a
$200 million committed credit facility ("Facility") to be utilized for tempo-
rary financing until the settlement of sale or purchase of portfolio securi-
ties, the repurchase or redemption of shares of the Funds at the request of the
shareholders and other temporary or emergency purposes. In connection there-
with, each Fund has agreed to pay a commitment fee, pro rata, based on the rel-
ative asset size of the Funds in the Facility. Interest is charged to each Fund
at rates based on prevailing market rates in effect at the time of borrowings.
For the year ended November 30, 1998, the Funds did not borrow under the Facil-
ity.

Federal Tax Status
 Each Fund intends to distribute all of its taxable income and to comply with
the other requirements of the Internal Revenue Code applicable to regulated in-
vestment companies. Accordingly, no provision for federal income taxes is re-
quired. In addition, by distributing during each calendar year substantially
all of its net investment income, capital gains and certain other amounts, if
any, each Fund intends not to be subject to a federal excise tax.
 For the year ended November 30, 1998, the reclassifications arising from per-
manent "book/tax" differences resulting in increases (decreases) to the compo-
nents of net assets were as follows:

ment Income Fund, Investment Grade Income Fund and High Income Fund had net
capital loss carryforwards of $84,620,234, $116,388,503, $18,781,340 and
$122,502,193, respectively. These loss carryforwards are available as reduc-
tions, to the extent provided in the regulations, of future net realized capi-
tal gains, and will expire between November 30, 1999 and November 30, 2006. To
the extent that such losses are used to offset future net realized capital
gains, it is probable that these gains will not be distributed.

 * Net of $0.06 contribution of capital from adviser. If such contribution had
   not been made the total investment returns would have been (7.02)% for Class
   A, (7.74)% for Class B and (7.50)% for Class C.
 + Includes 0.13% of interest expense related to the reverse repurchase
   agreement transactions entered into during the year.
(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each year reported, reinvestment of all dividends 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 sales charges; results would
    be lower if sales charges were included.
(2) During the year ended November 30, 1994 Mitchell Hutchins waived a portion
    of its advisory and administration fees. If such waivers had not been made
    the annualized ratios of expenses to average net assets, and net investment
    income to average net assets, respectively, would have been 0.88% and 5.12%
    for Class A, 1.66% and 4.35% for Class B, and 1.39% and 4.61% for Class C.

(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each period, reinvestment of all dividends 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 sales charges or program fees;
    results would be lower  if sales charges or program fees were included.
    Total investment return for a period of less than one year has not been
    annualized.

PaineWebber
Report of Ernst & Young LLP,
Independent Auditors
 
The Board of Trustees and Shareholders
PaineWebber Managed Investments Trust
 
 We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of PaineWebber U.S. Government Income
Fund, PaineWebber Low Duration U.S. Government Income Fund, PaineWebber
Investment Grade Income Fund and PaineWebber High Income Fund (four of the
portfolios of PaineWebber Managed Investments Trust) (the "Funds") as of
November 30, 1998, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
 We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of investments owned at November 30, 1998, by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
 In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
PaineWebber U.S. Government Income Fund, PaineWebber Low Duration U.S.
Government Income Fund, PaineWebber Investment Grade Income Fund and
PaineWebber High Income Fund at November 30, 1998, and the results of their
operations for the year then ended, the changes in their net assets for each of
the two years in the period then ended, and the financial highlights for each
of the indicated periods, in conformity with generally accepted accounting
principles.
 
                                                           /s/ Ernst & Young LLP

PaineWebber
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 each Fund's fiscal year end (November
30, 1998) as to the federal tax status of distributions received by
shareholders during such fiscal year from each Fund. Accordingly, we are
advising you that all of the distributions paid by PaineWebber U.S. Government
Income Fund, PaineWebber Low Duration U.S. Government Income Fund, PaineWebber
Investment Grade Income Fund and PaineWebber High Income Fund during the fiscal
year were derived from net investment income and are taxable as ordinary
income. Additionally, 2.00% of the distributions paid by PaineWebber High
Income Fund qualify for the dividend received deduction available for corporate
shareholders.
 
 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 reporting.
 
 Because each Fund's fiscal year is not the calendar year, another notification
will be sent in respect of calendar year 1998. The second notification, which
will reflect the amounts to be used by calendar year taxpayers on their federal
income tax returns, will be made in conjunction with Form 1099 DIV and is
mailed in January 1999. Some states exempt interest earned on direct
obligations of the federal government from state and local taxes. A portion of
the distribution paid by the PaineWebber U.S. Government Income Fund and
PaineWebber Low Duration U.S. Government Income Fund qualified as exempt-
interest dividends and therefore, are not subject to state and local income
taxes. Shareholders are advised to consult their own tax advisers with respect
to the tax consequences of their investment in each Fund.
 
                                                                              63
