PAINEWEBBER EQUITY FUNDS                                       SEMIANNUAL REPORT

                                                                  April 15, 2000

Dear Shareholder,

     We are pleased to present you with the semiannual report for PaineWebber
Growth and Income Fund, PaineWebber Mid Cap Fund and PaineWebber Growth Fund for
the six-month period ended February 29, 2000.

MARKET REVIEW

[GRAPHIC]

     Technology stocks continued to lead the equity markets during the six
months ended February 29, 2000. The NASDAQ Composite, one of the most
technology-heavy of the major market indices, surged 71.45% for the period. On
the other hand, the Standard and Poor's 500 Index (S&P 500) gained only 4.10%
for the period, and the Dow Jones Industrial Average lost 5.73%.

     Other trends of recent years also continued: an ever-smaller number of
stocks accounted for most of the market's gains, while day-today price
fluctuations became more volatile. In January 2000, the market briefly rewarded
investors who owned more cyclical, value-oriented stocks, but high-growth
technology stocks resumed their predominance in February.

OUTLOOK

     The near-term outlook for the market appears uncertain in light of recent
volatility among technology stocks and the likelihood that the Federal Reserve
(the Fed) will continue to raise interest rates. We are therefore concerned that
the stock market currently appears somewhat overvalued. Offsetting our concern,
however, expectations for corporate profits are rising. If these higher profit
expectations prove correct, then we believe the market can "grow into" its
current price levels without significant downside risk--barring an inflationary
shock.

     Despite some uncertainty, the longer-term picture looks positive. The
consensus estimate of real GDP growth in 2000 stands at about 3.4%; early
estimates for real GDP growth in 2001 stand at about 3.5%. It seems likely that
the economy will remain healthy, with tolerable inflation of around 2.5% per
year. Long-term interest rates, as gauged by the 30-year U.S. Treasury bond,
have been dipping below six percent. We believe the combination of lower
long-term rates and higher profit expectations will help support stock prices
over the longer term.

PORTFOLIO HIGHLIGHTS

     During the fiscal period we increased the Fund's exposure to technology and
reduced exposure to consumer cyclical companies. The strong performance of
technology benefited Fund performance. However, by period-end we began to reduce
the Fund's exposure to technology stocks, selling into strength and realizing
gains. Our models identified a number of attractively priced stocks in the
financial services sector, and we began to look for early indications of price
momentum there. We are seeing positive signs among brokerage companies, which
continue to report significantly better than expected earnings. We feel there is
opportunity here and believe these stocks will garner a lot of interest once
investors get a sense that the Federal Reserve (the Fed) is nearly finished
raising interest rates. Financial stocks tend to gain in anticipation of the
last Fed rate hike.

     The Fund is market weighted in most other areas except for utilities and
consumer nondurables. We would expect these sectors to do better in a more
recessionary economic environment, which we do not foresee. Therefore, we think
a pro-cyclical, pro-growth stance is appropriate at this time.

     The Fund's portfolio has taken on a "barbell" structure as we get mixed
readings from our valuation framework. We find stocks
<PAGE>

PAINEWEBBER EQUITY FUNDS                                       SEMIANNUAL REPORT

that look attractive based on their earnings momentum, earnings surprise and
price momentum; however, those stocks typically do not have much valuation
support. On the other hand, we see stocks that look cheap relative to their
valuations but that lack earnings acceleration and price momentum. The Fund's
mixture of both gets it to an aggregate valuation that is not much different
from that of the S&P 500.

     The Fund owns a mix of "old-economy" companies--energy, retail and
financial services--and "new-economy" technology companies connected to the
Internet. As the economy changes to a phase of higher energy costs and tighter
credit, market sentiment is seesawing between old and new. The new-economy
companies seem less dependent on energy prices and credit, but old-economy
companies are using new technologies to become more productive. At this point,
no one knows whether old or new will take the lead, but we believe the Fund is
well positioned to benefit either way.

PORTFOLIO HIGHLIGHTS

     For the six months ended February 29, 2000, the Fund strongly outperformed
its index and its Lipper peer group. The Fund did well because of its
significant exposure to telecommunications (11.2%) and technology (52.2%), and
its underweightings in financial services (4.7%) and healthcare (1.2%).*

     The Fund's growth focus also led us to underweight utility stocks. Fears of
increasing interest rates kept us out of the retail sector and kept our
weightings down in financial services. Thus, the Fund's leadership names
remained largely constant throughout the period.

     We added to the Fund's technology exposure during September and October,
and again in January. Exposure increased further in February, largely through
capital appreciation. We continue to watch for any slowing in the demand for
technology, which would lead us to shift into other less volatile, more
value-oriented sectors. We see no evidence of slowing demand yet, but we may
look to trade names within the Fund's technology exposure.

     The emphasis on technology followed our decision to place greater emphasis
on growth stocks, which we believe will continue to lead the market.
Nevertheless, we continue to make opportunistic trades in value-oriented stocks.
Within the mid-cap universe, we are looking for undervalued names that may be
little known due to lack of coverage by other investors. We also look for a
potential catalyst that could spark an acceleration of earnings growth, such as
new product introductions, management changes or increasing market share.

PORTFOLIO HIGHLIGHTS

     The Fund seeks to achieve its objective of long-term capital appreciation
by investing primarily in companies that we believe have a dominant position in
their industries, have strong management and are financially sound. We look for
companies that can deliver sustained or accelerating growth in earnings or cash
flow of at least 10% a year in each of the next three years. To help us identify
such companies, the Fund uses a proprietary quantitative model, which can point
us to what we should and should not own, and also provides a shopping list of
potential investments. We take that shopping list and conduct fundamental
analyses on the most attractive candidates.

     For the past six-month period we found most of our "best in class" picks in
our highest-weighted technology (42.9%) and consumer cyclical (26.0%) sectors,
which along with telecommunications (1.1%) were the key contributors to
performance during the period.* Our bias toward larger-cap securities has been
positive for the Fund. We continue to weed out smaller-cap issues when we
identify larger-cap opportunities with comparable upside potential.

     Our holdings are selected through a fundamental,

bottom-up process, yet they tend to reflect broad investment themes. Many times
these themes overlap a variety of industries. For example, we have long believed
that technological evolution is having, and will continue to have, a profound
impact on the way we conduct our businesses and our lives. Two more themes that
we believe affect a broad range of industries are the critical importance of
having strong brands and the need to establish a global presence.

     The recently announced merger of America Online, Inc. (AOL) (1.4%)* and
Time Warner, Inc. (TWX) (2.2%) demonstrates these themes. The dominant "content-
based" Internet player is combining with the leading global-branded media and
content provider, who is also the second largest cable operator in the United
States. Citigroup, Inc. (C) (0.5%), the dominant financial service company, also
embodies these themes with the global presence of Citibank now enhancing the
investment banking opportunities of Salomon Smith Barney. And Travelers
Insurance is a dominant brand in its industry. Wal- Mart Stores, Inc. (WMT)
(0.9%), the leading retailer in the United States, is also expanding
internationally, both internally and through acquisitions. Wal-Mart's recently
launched website brings e-commerce to the company, which has long been a pioneer
in the application of technology to the "back office" part of its operations.

     Because we take a fundamental approach to the companies in which the Fund
invests, we believe that these companies have the potential to deliver our
expected earnings growth over time. However, we are concerned about the current,
impulsive nature of the market, which can create unreasonable expectations,
excessively high valuations, and, in the dot.com mania, a definitely speculative
environment. Our challenge is to maintain prudence and redouble our efforts in
analyzing the fundamentals of the companies in which we are invested.

     As always, we do not make broad changes to the portfolio but look for
refinements. For example, during the past six-month period, we increased the
Fund's exposure to the technology sector. We did this selectively, focusing on
areas that we believe will have sustained growth and avoiding those areas we
consider highly speculative. We added Corning, Inc (0.5%) as a complement to JDS
Uniphase (4.9%) because of Corning's strong position in fiber optics; and we
initiated positions in IBM (0.7%) and Texas Instruments (0.6%).

     We continue to think that stock prices will be volatile and that there is
little leadership in the market. We strive, as always, to find the right balance
in our portfolio management between the more aggressive names and more
conservative names to mitigate volatility in the Fund.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 PaineWebber Growth and Income Fund ("Growth and Income Fund"), PaineWebber Mid
Cap Fund ("Mid Cap Fund") and PaineWebber Growth Fund ("Growth Fund")
(collectively, the "Funds") are diversified series of PaineWebber America Fund,
PaineWebber Managed Assets Trust and PaineWebber Olympus Fund (the "Trusts"),
respectively. The Trusts were organized under separate Declarations of Trust
and are registered with the Securities and Exchange Commission under the
Investment Company Act of 1940, as amended, as diversified open-end investment
companies.
 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.
 The preparation of financial statements in accordance with generally accepted
accounting principles requires Fund management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from those estimates. The following is
a summary of significant accounting policies:
 Valuation of Investments--The Funds calculate net asset values based on the
current market value for its portfolio securities. The Funds normally obtain
market values for the securities from independent pricing sources. Independent
pricing sources may use reported last sale prices, current market quotations or
valuations from computerized "matrix" systems that derive values based on com-
parable 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 val-
ued 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"), a wholly owned asset management subsidiary of PaineWebber Incorpo-
rated ("PaineWebber"), and investment adviser and administrator of the Funds.
If a market value is not available from an independent pricing source for a
particular security, that security is valued at fair market value as determined
in good faith by or under the direction of each Trust's board of trustee's (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 each Trust's board determines that this
does not represent fair value.
 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 includ-
ing 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 liqui-
date the collateral and apply the proceeds in satisfaction of the obligation.
Under certain circumstances, in the event of default or bankruptcy by the other
parts to the agreement, realization and/or retention of the collateral may be
subject to legal proceedings. Each Fund occasionally participates in joint re-
purchase 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

                                                                              31

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
on an accrual basis. Dividend income is recorded on the ex-dividend date. Dis-
counts are accreted and premiums are amortized as adjustments to interest in-
come and 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.
 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
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
security) 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. There were no options written for the Funds during the six months ended
February 29, 2000.
 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.
INVESTMENT ADVISER AND ADMINISTRATOR
 Each Trust's board has approved an Investment Advisory and Administration Con-
tract ("Advisory Contract") with Mitchell Hutchins, under which Mitchell
Hutchins serves as investment adviser and administrator of the Funds. In accor-
dance with the Advisory Contracts, Growth and Income Fund, Mid Cap Fund and
Growth 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 0.75%, respectively, of each Funds' average daily net assets. At Feb-
ruary 29, 2000, Growth and Income Fund, Mid Cap Fund and Growth Fund owed
Mitchell Hutchins $694,059, $177,208 and $335,884, respectively, in investment
advisory and administration fees. Mitchell Hutchins waived a portion of its in-
vestment advisory and administration fees in connection with the Mid Cap Fund's
and Growth Fund's investment of cash collateral from security lending in the
Mitchell Hutchins Private Money Market Fund LLC. For the six months ended Feb-
ruary 29, 2000, Mitchell Hutchins waived $5,461 and $15,505, respectively.
 For the six months ended February 29, 2000, Growth and Income Fund, Mid Cap
Fund and Growth Fund paid $45,345, $7,800, and $7,260, respectively, in broker-
age commissions to PaineWebber for transactions executed on behalf of the
Funds.
SERVICING AGREEMENT
 The board of Growth and Income Fund and Growth Fund have approved a Servicing
Agreement ("Servicing Agreement") with Mitchell Hutchins and the Mitchell
Hutchins Portfolios (comprising, respectively, the Aggressive Portfolio, Moder-
ate Portfolio and the Conservative Portfolio) (each a "Portfolio") pursuant to
an exemptive order from the Securities and Exchange Commission that permits the
Funds to reimburse each Portfolio for certain expenses to the extent a Fund re-
alizes

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
savings from each Portfolio. The savings to a Fund result from the elimination
of separate shareholder accounts for each Portfolio's investors, who otherwise
might invest directly in the Fund. For the six months ended February 29, 2000,
the Growth and Income Fund and Growth Fund incurred $6,365 and $5,597, respec-
tively, under the Servicing Agreement, which is included in other expenses on
the Statement of Operations. At February 29, 2000, Growth and Income Fund and
Growth Fund owed the Portfolios $6,365 and $5,597, respectively, under the Ser-
vicing Agreement. On March 28, 2000 the Portfolios will be liquidated: there
will be no reimbursements from that date on.
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 the an-
nual rate of up to 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 on Class B and Class C shares. At February 29,
2000, Growth and Income Fund, Mid Cap Fund and Growth Fund owed Mitchell
Hutchins $472,779, $79,829 and $171,252, respectively, in service and distribu-
tion fees.
 Mitchell Hutchins also receives the proceeds of the initial sales charges paid
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 six months ended
February 29, 2000, it earned $742,020, $18,660 and $160,777 in sales charges
for the Growth and Income Fund, Mid Cap Fund and Growth Fund, respectively.
SECURITY LENDING
 Each Fund may lend securities up to 33 1/2% 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. For the six months ended
February 29, 2000, the Growth and Income Fund, Mid Cap Fund and Growth Fund,
earned $2,507, $48,763 and $91,196, respectively, for lending securities. Each
Fund's lending agent is PaineWebber, who received $836, $16,545, and $30,903
for Growth and Income Fund, Mid Cap Fund and Growth Fund, respectively, in com-
pensation from the Funds in that capacity for the six months ended February 29,
2000. At February 29, 2000, Mid Cap Fund and Growth Fund owed PaineWebber
$2,727 and $3,410, respectively, in compensation.
 As of February 29, 2000 the Mid Cap Fund and Growth Fund held cash as collat-
eral for market value of securities loaned 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
temporary financing until the settlement of sale or purchase of portfolio
securities, the repurchase or redemption of shares of each Fund at the request
of the shareholders and other temporary or emergency purposes. In connection
therewith, each 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 each
Fund at rates based on prevailing market rates in effect at the time of
borrowings. For the six months ended February 29, 2000, the Funds did not
borrow under the Facility.

TRANSFER AGENCY SERVICE FEES
 PaineWebber provides transfer agency related services to the Funds pursuant to
a delegation of authority from PFPC, Inc., the Funds' transfer agent, and is
compensated for these services by PFPC, Inc., not the Funds. For the six months
ended February 29, 2000, PaineWebber received approximately 49%, 46% and 53% of
the total transfer agency and service fees collected by PFPC, Inc. from Growth
and Income Fund, Mid Cap Fund and Growth Fund, respectively.
