ANNUAL REPORT

Dear Shareholder,

We are pleased to present you with the annual report for the PaineWebber
Financial Services Growth Fund Inc., the PaineWebber Mid Cap Fund (formerly
Capital Appreciation Fund) and the PaineWebber Utility Income Fund for the
fiscal year ended March 31, 1998.


GENERAL MARKET OVERVIEW
================================================================================
[GRAPHIC]

     The implosion of the Asian markets in October 1997 caused worldwide
sell-offs in the stock markets and a "flight to quality" into the U.S. Treasury
bond market. As events unfolded, investors refocused on the underlying strength
of the U.S. economy and caused the stock market to stage a comeback to November.

     Volatility returned to the stock market in December as analysts lowered
their earnings estimates for 1998. The outlook turned more positive in January,
however, and the market stabilized by month-end. Sectors that fared poorly at
the end of 1997 turned in outstanding performances in early 1998. Technology
stocks, department stores, auto supply companies and airlines all rebounded
sharply from year-end slumps. Financial services companies did reasonably well.
Energy stocks performed the worst as weakening economies in Asia drove down oil
prices. Consumer nondurables, a traditionally defensive sector, continued to
lag.

PORTFOLIO REVIEW
================================================================================
[GRAPHIC]

     Performance--The Fund's total return (the net asset value change with
dividends reinvested) for the fiscal year ended March 31, 1998, without
deducting sales charges, was 51.92% for Class A shares, 50.80% for Class B
shares and 50.76% for Class C shares. The commencement of issuance for Class Y
shares is March 30, 1998. The total return for the two-day period ended March
31, 1998 was 1.02% with and without deduction of sales charges.

     For shareowners who purchased or redeemed Fund shares during the period,
the Fund's total return may be lower; for example, after deducting the maximum
applicable sales charges, the Fund's total return for the period was 45.10% for
Class A shares, 45.80% for Class B shares and 49.76% for Class C shares. The
commencement of issuance for Class Y shares is March 30, 1998. The total return
for the two-day period ended March 31, 1998 was 1.02% with and without deduction
of sales charges.

     Portfolio Highlights--Financial stocks, a standout all through the bull
market, rose 10.9% in the first quarter of 1998, trailing the broad S&P 500
Index 13.9% return. This lag may be at

least partially attributable to the slowing of the bond market. In general, bank
stocks outperformed nonbanks and larger financial services companies
outperformed smaller ones.

     Consolidation is under way in the financial services industry, as companies
compete to sell more products in more markets: the recently announced
Citicorp/Travelers merger is just the latest and largest confirmation of this
trend. The House of Representatives recently voted to overturn the
Glass-Steagall Act and allow more firms to sell more kinds of products. If the
House legislation is enacted, it will further blur the distinctions among banks,
securities firms and insurers. Industry consolidation is likely to speed up as a
result.

     We seek to diversify the Fund's portfolio--as much as is possible in a
sector fund --by investing in banks and nonbanks, which should benefit from
liberalized regulation, mergers and acquisitions and, most important, rising
demand for financial services from an aging U.S. population.

     Recent purchases include Fremont General (1.25% of net assets on March 31,
1998), a West Coast workers' compensation insurer serving markets where pricing
is improving dramatically; Exel Limited (1.15%), a Bermuda insurer whose
competitive edge is derived from superior management as well as tax advantages;
and Wachovia (1.26%), a Southeast based bank focused on expanding in its
traditional markets.

PAINEWEBBER MID-CAP FUND (FORMERLY CAPITAL APPRECIATION FUND)

     Performance--The Mid Cap Fund's total return (the net asset value change
with dividends reinvested) for the fiscal year ended March 31, 1998, without
deducting sales charges, was 41.50% for Class A shares, 40.39% for Class B
shares and 40.46% for Class C shares. The commencement of issuance date for
Class Y shares is March 17, 1998. The total return for the 15-day period ended
March 31, 1998 was 0.67% for Class Y shares, with and without deduction of sales
charges.

     For shareowners who purchased or redeemed Fund shares during the period the
Fund's total return may be lower; for example, after deducting the maximum
applicable sales charges, the Fund's total return for the period was 35.17% for
Class A shares, 35.39% for Class B shares and 39.46% for Class C shares. The
commencement of issuance date for Class Y shares is March 17, 1998. The total
return for the 15-day period ended March 31, 1998 was 0.67% for Class Y shares,
with and without deduction of sales charges.

     Management Change--The Fund's performance was in line with the S&P 400
Midcap Index during the quarter. The Fund's long-term performance, however, had
been disappointing relative to its benchmark and its peer group. As a result, on
May 1, 1998, Mitchell Hutchins Asset Management took over day-to-

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

day management of the Fund from Denver Investment Advisors, and implemented a
new investment discipline.

     Mitchell Hutchins has developed a strong equity management team over the
past three years, headed by Chief Investment Officer of Equities Mark A.
Tincher. Prior to joining the firm he directed U.S. equity funds management and
equity research for Chase Manhattan Private Bank.

     Along with Mr. Tincher, Portfolio Managers Christopher G. Altschul and
Antony J. Scott will be responsible for day-to-day management of the Fund. Mr.
Altschul joined the team in 1995. He maintains the quantitative equity valuation
model used to develop investment ideas for the Fund. Prior to joining Mitchell
Hutchins Mr. Altschul was a stock analyst at Chase Manhattan Bank. Mr. Scott
joined the firm in 1996 as an analyst; he covers the technology, media,
entertainment and medical products industries. Formerly he was an analyst at
Morgan Stanley.

     The Fund's new investment discipline:

o Seeks investments primarily in mid-cap companies with market capitalizations
between $750 million and $6 billion at the time of purchase.

o Relies on the Mitchell Hutchins Factor Valuation Model, which screens a
universe of companies from ten business sectors to identify undervalued
companies with strong earnings momentum. Stocks must rank well based on
valuation and earnings momentum measures, as well as economic sensitivity
measures.

o The Mitchell Hutchins Equity Research Team applies fundamental analysis to all
purchase candidates. 

     Mitchell Hutchins expects to restructure about half of the Fund's portfolio
to reflect the new investment approach. During this restructuring period, the
Fund is closed to new purchases and exchanges from May 1, 1998 to June 24, 1998.
Fund shares may be redeemed during this period. We expect the Fund to pay a
capital gains distribution to shareholders of record on June 16, 1998. The Fund
will reopen to new purchases and exchanges into the Fund on June 25, 1998.

     Portfolio Highlights--The Fund benefited from its holdings in technology,
telecommunications and specialty retailers. Among these (as percent of net
assets on March 31, 1998) were Concentric Network Corp. Delaware (0.2%), an
internet networking firm; WorldCom, Inc. (4.3%), an integrated long distance and
internet provider; and TJX Companies, Inc. (0.6%), the holding company for the
TJ Maxx and Marshall's stores.

================================================================================

PAINEWEBBER UTILITY INCOME FUND

     Performance--The Fund's total return (the net asset value change with
dividends reinvested) for the fiscal year ended March 31, 1998, without
deducting sales charges, was 39.15% for Class A shares, 38.13% for Class B
shares and 38.09% for Class C shares. There were no Class Y shares outstanding
during the year ended March 31, 1998.

     For shareowners who purchased or redeemed Fund shares during the period the
Fund's total return may be lower; for example, after deducting the maximum
applicable sales charges, the Fund's total return for the period was 32.90% for
Class A shares, 33.13% for Class B shares and 37.09% for Class C shares.

     Portfolio Highlights--At the end of January, investors confidently looked
beyond Asia'a negative impact on corporate earnings and shifted away from
defensive sectors such as utilities. The utility sector, as measured by the New
York Stock Exchange Utilities Index, returned 14.3% for the first quarter of
1998, in line with the S&P 500 return of 13.9% but down dramatically from its
ten-percentage point lead over the S&P 500 in the fourth quarter of 1997.

     We think deregulation of the telecommunications industry will redistribute
assets among long distance and local telephone companies. In the first quarter
the Fund benefited from Qwest Communications International's proposed
acquisition of LCI International Inc. Both companies are long distance providers
competing to build integrated networks that offer telephone and Internet
services. LCI represented 2.1% of the Fund's net assets on March 31, 1998.

     The Fund's performance was hurt somewhat by its exposure to real estate
investment trusts (REITs) during the last quarter. Nonetheless, we still believe
that selected REITs offer attractive total return potential. Our holdings are
positioned in industries with strong dynamics, particularly the hotel and office
property industries, which are benefiting from limited supply and growing
demand.

     One-third of the portfolio is currently invested in electric utilities
serving strong regional economies, companies that are becoming more productive
ahead of deregulation.


OUTLOOK
================================================================================

[GRAPHIC]
   With inflation nearly absent, we expect the Federal Reserve to remain on
hold, and anticipate a fairly stable interest rate environment. In these
conditions stock selection--particularly attempting to avoid companies that may
produce negative surprises--will be of critical importance.

   Meanwhile, the extent of the economic turmoil in Asia and its ultimate impact
on corporate profits remain unclear. We are cautious in the near term and expect
continued choppy markets ahead as the effect of negative earnings announce-ments
takes its toll. Over the longer term, however, we see little cause for the
market to lose strength.

NOTES TO FINANCIAL STATEMENTS
ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 PaineWebber Financial Services Growth Fund Inc. ("Financial Services Growth
Fund"), PaineWebber Mid Cap Fund ("Mid Cap Fund", which prior to May 1, 1998
was known as the PaineWebber Capital Appreciation Fund) and PaineWebber Utility
Income Fund ("Utility Income Fund") (collectively, the "Funds") are registered
with the Securities and Exchange Commission under the Investment Company Act of
1940, as amended, as diversified open-end management investment companies. Fi-
nancial Services Growth Fund was incorporated in the state of Maryland on Feb-
ruary 13, 1986, Mid Cap Fund is a series of PaineWebber Managed Assets Trust
and Utility Income Fund is a series of PaineWebber Managed Investments Trust
(collectively, the "Trusts") which were organized under Massachusetts law by a
Declaration of Trust dated August 9, 1991 and November 21, 1986, respectively.
Organizational costs have been deferred and are being amortized using the
straight line method over a period not to exceed 60 months from the date the
Funds commenced operations.
 
 Currently, each Fund offers Class A, Class B, Class C and Class Y shares.
Utility Income Fund had no 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 distribution charges and certain transfer agency expenses.
In addition, Class B shares and all corresponding reinvested dividend shares

All classes of shares have equal voting privileges except that each class has

 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--Securities which are listed on stock exchanges are
valued at the last sales price on the day the securities are being 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 Man-
agement Inc. ("Mitchell Hutchins"), an asset management subsidiary of
PaineWebber Incorporated ("PaineWebber") and investment adviser, administrator
and distributor of the Funds'. Prior to May 1, 1998, when Mitchell Hutchins as-
sumed the day to day management responsibility, Denver Investment Advisors,
LLC, served as Mid Cap Funds' sub-adviser. Securities traded in the over-the-
counter ("OTC") market and listed on the Nasdaq Stock Market, Inc. ("Nasdaq")
are valued at the last available sales price, or last bid price available if no
sale occurs on Nasdaq prior to the time of valuation. Where market quotations
are readily available, debt securities are valued thereon, provided such quota-
tions adequately reflect the fair values of the securities in the judgement of
Mitchell Hutchins. 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. The amortized cost method of valuation is used to value short-term debt
instruments with sixty days or less remaining to maturity. Securities for which
market quotations are not readily available including restricted securities
subject to limitations as to their sale are valued at fair value as determined
in good faith by, or under the direction of, the Fund's/Trusts' Board of
Directors/Trustees.

NOTES TO FINANCIAL STATEMENTS
 
 Repurchase Agreements--Each Fund's custodian takes possession of the collat-
eral pledged for investments in repurchase agreements. The underlying collat-
eral is valued daily on a mark-to-market basis to ensure that the value, in-
cluding accrued interest, is at least equal to the repurchase price. In the
event of default of the obligation to repurchase, each Fund has the right to
liquidate the collateral and apply the proceeds in satisfaction of the obliga-
tion. 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. Each Fund occasionally participates in
joint repurchase 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 on an accrual basis. Dividend income is recorded on the ex-dividend
date. Discounts are accreted and premiums are amortized as adjustments to in-
terest income and the identified costs 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.
 
 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" differ-
ence 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 dif-
ferences do not require reclassification.
 
CONCENTRATION OF RISK
 
 Financial Services Growth Fund invests primarily in equity securities of fi-
nancial services companies and Utility Income Fund invests primarily in securi-
ties of utility companies. Economic, legislative and regulatory developments
impacting those industries may affect the market value of each Fund's invest-
ments. The Mid Cap Fund invests primarily in equity securities of medium-sized
companies, which may entail greater market volatility and risks of adverse fi-
nancial developments than is the case for securities of larger companies. In
addition, each Fund's ability to invest in U.S. dollar-denominated foreign eq-
uity securities and ability to use options and futures contracts also entail
special risks.
 
INVESTMENT ADVISER AND ADMINISTRATOR
 
 Each Fund has an Investment Advisory and Administration Contract ("Advisory
Contract") with Mitchell Hutchins, under which Mitchell Hutchins serves as in-
vestment adviser and administrator of the Funds. In accordance with the Advi-
sory Contracts, Financial Services Growth Fund, Mid Cap Fund and Utility Income
Fund pay Mitchell Hutchins an investment advisory and administration fee, which
is accrued daily and paid monthly, at the annual rate of 0.70%, 1.00% and
0.70%, respectively, of
 
                                                                              27

each Funds' average daily net assets. At March 31,1998, Financial Services
Growth Fund, Mid Cap Fund and Utility Income Fund owed Mitchell Hutchins
$262,646, $230,149, and $21,634, respectively, in investment advisory and ad-
ministration fees.
 
 Prior to May 1, 1998, Denver Investment Advisors served as the sub-adviser to
the Mid Cap Fund pursuant to a sub-advisory contract with Mitchell Hutchins.
Mitchell Hutchins (not the Fund) paid Denver a monthly fee in an amount equal
to 50% of the fee paid to Mitchell Hutchins under the Advisory Contract.
 
 For the year ended March 31, 1998, Financial Services Growth Fund, Mid Cap
Fund and the Utility Income Fund paid $17,496, $0 and $0, respectively, in bro-
kerage commissions to PaineWebber for transactions executed on behalf of 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 Class A, Class B and
Class C shares, the Funds pay Mitchell Hutchins monthly service fees at an an-
nual 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% of the
average daily net assets of Class B and Class C shares. At March 31, 1998, Fi-
nancial Services Growth Fund, Mid Cap Fund and Utility Income Fund owed Mitch-
ell Hutchins $247,803, $165,797 and $26,048, respectively, in service and dis-
tribution 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 charges paid by shareholders upon certain redemptions of Class A, Class B
and Class C shares. Mitchell Hutchins has informed each Fund that for the year
ended March 31, 1998, it earned $2,215,324, $288,384, and $89,852 in sales
charges for the Financial Services Growth Fund, Mid Cap Fund and Utility 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, which received compensation from the Funds for the year
ended March 31, 1998 as follows:

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 each Fund 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 March 31, 1998, the Funds did not borrow under the Facility.
 
TRANSFER AGENCY SERVICE FEES
 
 Prior to August 1, 1997, each Fund paid PaineWebber an annual fee of $4.00 per
active PaineWebber shareholder account for certain services not provided by the
Fund's transfer agent. For these services for the four months ended July 31,
1997, PaineWebber earned $14,088, $28,077 and $4,244 from Financial Services
Growth Fund, Mid Cap Fund and Utility Income Fund, respectively. Beginning on
August 1, 1997, PaineWebber provides transfer agency related services to each
Fund pursuant to a delegation of authority from PFPC, Inc., the Fund's transfer
agent, and is compensated for these services by PFPC, Inc., not the Funds. For
the period August 1, 1997 through March 31, 1998, PaineWebber received from
PFPC, Inc., not the Funds, approximately 51%, 56% and 54% for Financial Serv-
ices Growth Fund, Mid Cap Fund and Utility Income Fund, respectively, of the
total transfer agency fees collected by PFPC, Inc. from the Funds.

FEDERAL TAX STATUS
 
 The Funds intend to distribute substantially all of their 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 sub-
stantially all of their net investment income, capital gains and certain other
amounts, if any, the Funds intend not to be subject to a federal excise tax.
 
 At March 31, 1998, Utility Income Fund had a net capital loss carryforward of
$3,858,250 which will expire by March 31, 2003. 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.
 
 To reflect reclassification for the Mid Cap Fund arising from permanent
"book/tax" differences for the year ended March 31, 1998, undistributed net in-
vestment income was increased by $4,451,494 and capital stock was decreased by
$4,451,494 to reclassify the net operating loss for the fiscal year ended March
31, 1998.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Boards of Trustees/Directors and Shareholders
 
 We have audited the accompanying statement of assets and liabilities, includ-
ing the portfolios of investments, of PaineWebber Financial Services Growth
Fund, Inc., PaineWebber Mid Cap Fund (formerly the PaineWebber Capital Appreci-
ation Fund), and PaineWebber Utility Income Fund as of March 31, 1998, and the
related statement of operations for the year then ended and the statements 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 fi-
nancial statements and financial highlights are the responsibility of the
Funds' management. Our responsibility is to express an opinion on these finan-
cial statements and financial highlights based on our audits.
 
 We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements and financial high-
lights 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 March 31, 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 fi-
nancial 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 Financial Services Growth Fund, Inc., PaineWebber Mid Cap Fund and
PaineWebber Utility Income Fund at March 31, 1998, the results of their opera-
tions for the year then ended and 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 princi-
ples.

*Taxable as ordinary income
 
 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 re-
porting.
 
 Since each Fund's fiscal year is not the calendar year, another notification
will be sent with respect to calendar year 1998. Such notifications, which will
reflect the amount to be used by calendar year taxpayers on their federal in-
come tax returns, will be made in conjunction with Form 1099 DIV and will be
mailed in January 1999. Shareholders are advised to consult their own tax ad-
visers with respect to the tax consequences of their investment in each of the
Funds.
