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 six funds: PaineWebber Low Duration U.S.
Government Income Fund ("Low Duration U.S. Government Income Fund"),
PaineWebber U.S. Government Income Fund ("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 Utility Income Fund and the newly created PaineWebber Asia Pacific
Growth Fund. The financial statements for PaineWebber Utility Income Fund and
PaineWebber Asia Pacific Growth Fund are not included herein.
 Costs incurred by Low Duration U.S. Government Income Fund in connection with
its organization have been deferred and are being amortized using the straight-
line method not to exceed sixty months from the commencement of operations.
 Currently, each Fund offers Class A, Class B, Class C and Class Y shares. Only
Low Duration U.S. Government Income Fund and U.S. Government Income Fund had
Class Y shares outstanding during the period. 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 distribu-
tion 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.
 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 subsidiary of
PaineWebber Incorporated ("PaineWebber") and investment adviser and administra-
tor of the Funds. When market quotations are not readily available, securities
are valued based upon appraisals derived from information concerning those se-
curities or similar securities received from recognized dealers in those secu-
rities. All other securities are valued at fair value as determined in good
faith by or under the direction of the Trust's board of trustees. 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 maturi-
ty, unless the Trust's board of trustees determines that this does not repre-
sent 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.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

 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 on an accrual basis. Dividend income is recorded on the ex-dividend
date. Discounts are accreted and premiums are amortized (with the exception of
U.S. Government Income Fund) as adjustments to interest income and the identi-
fied cost of investments. Low Duration U.S. Government Income Fund and U.S.
Government Income Fund may enter into transactions in which the Funds sell se-
curities for delivery in the current month and simultaneously contract to re-
purchase substantially similar (same type, coupon and maturity) securities on a
specified future date (the "roll period"). During the roll period the Fund for-
goes principal and interest paid on the securities. The Funds are compensated
by the interest earned on the cash proceeds of the initial sale and by fee in-
come or a lower repurchase price.
 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.
 Futures Contracts--Upon entering into a financial futures contract, a Fund is
required to pledge to a broker an amount of cash and/or U.S. Government securi-
ties 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 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 U.S. Government Income Fund primarily used financial futures contracts to
manage the average duration of the Fund's portfolio. However, imperfect corre-
lations 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 a 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 Assets
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 expires
on its stipulated expiration date or the Fund enters into a closing purchase
transaction, the Fund realizes a gain (or loss if the cost of a closing pur-
chase 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.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

 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.

INVESTMENT ADVISER AND ADMINISTRATOR
 The Trust's board of trustees has approved an Investment Advisory and Adminis-
tration Contract ("Advisory Contract") with Mitchell Hutchins, under which
Mitchell Hutchins serves as investment adviser and administrator of the Funds.
In accordance with the Advisory Contract, each 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 each Fund's average daily net assets.
At May 31, 1997, Low Duration U.S. Government Income Fund, U.S. Government In-
come Fund, Investment Grade Income Fund and High Income Fund owed Mitchell
Hutchins $69,822, $166,286, $121,650 and $238,574, respectively, in investment
advisory and administration fees.
 Under a separate contract with Mitchell Hutchins ("Sub-Advisory Contract"),
Pacific Investment Management Company ("PIMCO") serves as the sub-adviser for
Low Duration U.S. Government Income Fund. Under the Sub-Advisory Contract,
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 May 31, 1997, Low Duration U.S. Government Income Fund, U.S.
Government Income Fund, Investment Grade Income Fund and High Income Fund owed
Mitchell Hutchins $83,983, $127,494, $103,300 and $298,883, respectively, in
service and distribution fees.
 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 six months ended May 31, 1997, it earned $15,287, $105,236, $107,800
and $493,553 in sales charges for the Low Duration U.S. Government Income Fund,
U.S. Government Income Fund, Investment Grade Income Fund and High Income Fund,
respectively.
SECURITY LENDING
 Each Fund may lend up to 33 1/3% of its total assets to qualified institu-
tions. 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. Each
Fund will regain record ownership of loaned securities to exercise certain ben-
eficial rights, however, each Fund may bear the risk of delay in recovery of,
or even loss of rights in, the securities loaned should the borrower fail fi-
nancially. Each Fund receives compensation, which is included in interest in-
come, for lending its securities from interest earned on the cash or U.S. gov-
ernment securities held as collateral, net of fee rebates paid to the borrower
plus reasonable administrative and custody fees. Each Fund's lending agent is
PaineWebber, who received $495 in compensation from the U.S. Government Income
Fund for the six months ended May 31, 1997.
 As of May 31, 1997, U.S. Government Income Fund's custodian held cash and cash
equivalents having an aggregate value of $364,000 as collateral for portfolio
securities loaned having a market value of $352,670 for the U.S. Government In-
come Fund.
TRANSFER AGENCY SERVICE FEES

shareholder account for certain services not provided by the Funds' transfer
agent. For these services for the six months ended May 31, 1997, PaineWebber
earned $28,308, $56,406, $36,634 and $61,239 in transfer agency service fees
from Low Duration U.S. Government Income Fund, U.S. Government Income Fund, In-
vestment Grade Income Fund and High Income Fund, respectively. At May 31, 1997,

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.
 At November 30, 1996, Low Duration U.S. Government Income Fund, U.S. Govern-
ment Income Fund, Investment Grade Income Fund and High Income Fund had net
capital loss carryforwards of $120,452,991, $127,715,208 $43,150,005 and
$208,319,708, 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, 1997 and November 30, 2004. 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.

    A, (7.74)% for Class B and (7.50)% 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; results for
    Class A, Class B and Class C would be lower if sales charges were included.
    Total investment return for periods less than one year has not been
    annualized.
(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.
