PAINEWEBBER STRATEGIC INCOME FUND                                  ANNUAL REPORT

                                                                January 23, 1998


Dear Shareholder,

         We are pleased to present you with the annual report for the
PaineWebber Strategic Income Fund for the year ended November 30, 1997.


GENERAL MARKET OVERVIEW
- --------------------------------------------------------------------------------

         1997 was a particularly good year for bond investors. Defying the
experts who worried about the economy's high utilization rates and its possible
effect on inflation, economic growth rose at a robust 3.5% rate, unemployment
fell to 4.7%, wages rose only slightly and the annual inflation rate closed out
1997 at 1.7%. Fixed income investors shrugged off inflation warnings and bought

bonds; the Lehman Brothers Aggregate Bond Index returned 7.6% in the year ended
November 30, 1997. The benchmark 30-year Treasury bonds yield fell from over
6.4% to just over 6.0% during the same timeframe.

         While stable inflation created market conditions ripe for a bond rally,
several technical factors also helped support prices. U.S. stock investors
experienced the first stall in a two and a half year bull run that started in
1995--money began trickling back into bond funds last year at about three times
the rate of the year before. And, overshadowing all these events, the economic
crisis in Asia prompted many individuals to buy Treasury bonds.

         Most of the bond market advances were in longer-term bonds. Due to
expectations for Asia-related interest rate volatility, short-term rates did not
fall to the same degree as long-term rates (the yield curve flattened, in market
parlance).

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

         The PaineWebber Strategic Income Funds total return (the net asset
value change with dividends reinvested) for the year ended November 30, 1997
without deducting sales charges, was 10.0%, 9.2% and 9.4% for Class A, B and C
shares, respectively. Comparable funds, measured by the Lipper Multi-Sector
Income Funds Average, were up 8.1% over the same period. During this reporting
period, shareholders who purchased or redeemed Fund shares may have received a
lower total return. For example, after deducting the maximum applicable sales
charges, the Funds total return was 5.6%, 4.2% and 8.6% for Class A, B and C
shares, respectively.

         The PaineWebber Strategic Income Fund invests in three main bond
markets, with the flexibility to shift assets among sectors as market conditions
change. On November 30, 1997, the Fund had 37% of net assets in U.S.
high-yield/high-risk securities, 47% in U.S. government and investment grade
corporate bonds, and 11% in foreign and emerging market debt securities. This
allocation reflected our expectation for a late-year rally in U.S. interest
rates.

PAINEWEBBER STRATEGIC INCOME FUND                                  ANNUAL REPORT

High Yield Sector

         Our high-yield, high-risk holdings hovered at about 50% of portfolio
assets for much of the year, but we sold some of these bonds in the fourth
quarter, to shift assets into U.S. government bonds. This allowed us to avoid
seasonal dips in high-yield bond prices that usually accompany heavy end-of-year
issuance calendars, and to take advantage of an expected Treasury rally. The
strategy paid off as, at this writing, the long-term Treasury bond is back near
historical lows, under 6%.

         While high-yield, high-risk bonds tend to track both the bond and stock

markets, the Treasury markets movements dominated returns in 1997. In this
positive economic environment, our investment strategy was dominated by a search
for fundamental value within companies and industries on a global basis. We
measure value based on a company's interest coverage and debt-to-cash flow
ratios. Then, we analyze the security's potential for total return, yield or
spread to a comparable Treasury security, depending on the individual issue.

         Our emphasis on communications companies, especially European telecom
providers that should benefit from industry deregulation in 1998, helped boost
the Funds returns in 1997. We believe companies like the U.K.'s Colt Telecom
Group PLC (0.9% of net assets on 11/30/97) are poised to take advantage of new
freedom to expand their operations into other European countries.

         Another company we like is Nextel Communications Incorporated (2.1% of
net assets on 11/30/97), a cellular phone manufacturer. Nextel has a unique
product and nationwide coverage, but we feel the price is still very low
compared to that of similar competitors--we expect it to catch up in coming
months.

         We are expecting short-term volatility in the bond market as investors
assimilate daily reports from Asia, and as we begin to see how much the U.S.
economy is affected by the crisis across the Pacific. Long-term, however, we
believe the U.S. economy will not be dramatically affected and high-yield bonds
should continue to produce respectable returns. We positioned the portfolio
aggressively to take advantage of a rally by selling some BB-rated credits to
buy B-rated bonds. These lower-quality securities typically profit the most from
high-yield bond market rallies.

U.S. Government Sector

         Our emphasis on mortgage-backed securities (34% of net assets on
11/30/97) last year paid off as investors flocked to mortgages to benefit from

                                                                               3

their income advantage compared to Treasury securities. Towards the end of the
year, as interest rates began to fall precipitously, we shifted some assets out
of fixed-rate mortgages into low-coupon adjustable-rate and commercial
mortgage-backed securities. These bonds tend to perform well when interest rates
are falling because they don't suffer as much from prepayment risk as generic
fixed-rate securities.

    While the economy remains on a solid domestic footing, the export sector's
drag on economic growth, coupled with the strong dollar's impact on imports (and
the consequent dampening influence on inflation), may point to lower rates, at
least in the early part of 1998. We expect to continue to avoid U.S. Treasury
securities, because higher-yielding agency and mortgage bonds should continue to
add value to the portfolio's performance. As we expect some volatility and
higher prepayment risk, however, we will be very selective about the individual
bonds purchased for the portfolio.


GLOBAL SECTOR

    Global bonds can be divided into two sectors--developed market bonds and
sovereign emerging market debt--each of which has different risk/return
characteristics. For most of the year, we maintained roughly one-fourth of the
Fund's assets in global bonds and varied the allocation between the two groups
substantially.

    Returns of global bonds denominated in most foreign currencies suffered from
the stronger dollar. We took little currency exposure during the year.

    We did invest on an unhedged basis in U.K. Gilts (2.5% of net assets on
11/30/97); however, the British pound did not depreciate against the dollar over
the year. Despite the strong U.K. economy, Gilts performed well over the year,
as investors perceived the economic policies of the newly elected Labour party
favorably. These policies included steps to make the Bank of England more
independent from the government.

    We cut the Fund's sovereign emerging market debt exposure during October. We
switched Brazilian Brady bonds into Mexican Brady bonds (Brady bonds are
sovereign foreign debt that is backed by a U.S. repayment guarantee), which have
outperformed most other emerging market debt since October's Asian crisis began.
We also have a position in Polish Brady bonds, which have remained relatively
stable as other emerging market bonds sold off.

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

    In general, we are still bullish on bonds, although the markets may be
volatile in the beginning of 1998. Foreign interest in U.S. bonds remains
strong, domestic buying should pick up if the stock market turns in a few more
lackluster quarters, and the supply of government bonds should continue to
contract as the U.S. budget deficit dwindles. Nonetheless, years of borrowing
have left the U.S. with over $5 trillion in debt. How the government spends its
newfound surpluses may be key to the bond market's health going into the new
millennium.

(1)      Figures assume reinvestment of all dividends and other distributions at
         net asset value on the payable dates and do not include sales charges;
         results would be lower if sales charges were included.

(2)      Includes foreign exchange gain distributions, if any.

         Note: The Fund offers Class Y shares to a limited group of investors,
         including participants in certain programs that are sponsored by
         PaineWebber and that may invest in PaineWebber mutual funds. No Class Y
         shares have been issued to date.

         The above data represents past performance of the Fund's shares, which
         is no guarantee of future results. 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.

NOTES TO FINANCIAL STATEMENTS

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

         PaineWebber Strategic Income Fund (the "Fund") is a series of
PaineWebber Securities Trust (the "Trust") which was organized under
Massachusetts law by a Declaration of Trust dated December 3, 1992 and is
registered with the Securities and Exchange Commission under the Investment
Company Act of 1940, as amended, as an open-end, diversified investment company.

         Costs incurred by the Fund in connection with its organization have
been deferred and are being amortized using the straight-line method over a
period not to exceed sixty months from the commencement of operations.

         Currently, the Fund offers Class A, Class B, Class C and Class Y shares
(no Class Y shares were outstanding during the period). Each class represents
interests in the same assets of the 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
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--Securities which are listed on U.S. and
foreign stock exchanges are valued at the last sale 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 Management Inc. ("Mitchell Hutchins"), a
wholly owned asset management subsidiary of PaineWebber Incorporated
("PaineWebber") and investment adviser and administrator of the Fund. Securities
traded in the over-the-counter ("OTC") market and listed on The Nasdaq Stock
Market ("Nasdaq") are valued at the last trade price on Nasdaq prior to the time
of valuation. Other OTC securities are valued at the last bid price available in
the OTC market prior to the time of valuation. The amortized cost method of
valuation is used to value short-term debt instruments with sixty days or less
remaining to maturity. Securities and assets 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 under the
direction of the Trust's board of trustees. All investments quoted in foreign
currencies will be valued daily in U.S. dollars on the basis of the foreign
currency exchange rates prevailing at the time such valuation is determined by
the Fund's custodian.

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

                                                                              15

<PAGE>

NOTES TO FINANCIAL STATEMENTS

         Repurchase Agreements--The Fund's custodian takes possession of the
collateral pledged for investments in repurchase agreements. The underlying
collateral is valued daily on a mark-to-market basis to ensure that the value,
including accrued interest, is at least equal to the repurchase price. In the
event of default of the obligation to repurchase, the Fund has the right to
liquidate the collateral and apply the proceeds in satisfaction of the
obligation. Under certain circumstances, in the event of default or bankruptcy
by the other party to the agreement, realization and/or retention of the
collateral may be subject to legal proceedings. The Fund occasionally
participates in joint repurchase agreement transactions with other funds managed
by Mitchell Hutchins.

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

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

value of dividend-eligible shares, as appropriate) of each class at the
beginning of the day (after adjusting for current capital share activity of the
respective classes). Class-specific expenses are charged directly to the
applicable class of shares.

         Foreign Currency Translation--The books and records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:

         (1) market value of investment securities, other assets and
         liabilities--at the exchange rates prevailing at the end of the period.

         (2) purchases and sales of investment securities, income and expenses
         at the rates of exchange prevailing on the respective dates of such--
         transactions.

         Although the Fund's net assets including the market values of the
Fund's investments are presented at the foreign exchange rates at the close of
the period, the Fund does not generally isolate the effect of fluctuations in
foreign exchange rates from the effect of the changes in market prices of
securities. However, the Fund does isolate the effect of fluctuations in foreign
exchange rates when determining the gain or loss upon the sale or maturity of
foreign currency-denominated debt obligations pursuant to federal income tax
regulations.

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

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

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

16

<PAGE>

NOTES TO FINANCIAL STATEMENTS

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

matured.

         Futures Contracts--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
securities 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 gain or loss.

         Using financial futures contracts involves various market risks. The
maximum amount at risk from the purchase of a futures contract is the contract
value. The Fund primarily used financial futures contracts for hedging purposes
and not for leverage. 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.

         Dividends and Distributions to Shareholders--Dividends and 
distributions to shareholders are recorded on the ex-dividend date. The amount
of dividends and distributions are determined in accordance with federal income
tax regulations which may differ from generally accepted accounting principles.
These "book/tax" differences are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification.

CONCENTRATION OF RISK

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

BANK LINE OF CREDIT

         The Fund may participate with other funds managed by Mitchell Hutchins
in a $200 million secured credit facility ("Facility") to be used for repayment
by the Fund of loans outstanding under this agreement, temporary financing until
the settlement of sale or purchase of portfolio securities, the repurchase or
redemption of shares of the Fund at the request of the shareholders and other
temporary or emergency purposes. In connection therewith, the Fund has agreed to
pay commitment fees on its pro rata portion of the Facility. Interest is charged
to the Fund at rates based on prevailing market rates in effect at the time of
borrowings. For the year ended November 30, 1997, the Fund did not borrow under

the Facility.

INVESTMENT ADVISER AND ADMINISTRATOR

         The Trust's board of trustees has approved an Investment Advisory and
Administration Contract ("Advisory Contract") with Mitchell Hutchins, under
which Mitchell Hutchins serves as investment adviser and administrator of the
Fund. In accordance with the Advisory Contract, the Fund pays Mitchell Hutchins
an investment advisory and administration fee, which is

                                                                              17

NOTES TO FINANCIAL STATEMENTS

accrued daily and paid monthly, at the annual rate of 0.75% of the Fund's
average daily net assets. At November 30, 1997, the Fund owed Mitchell Hutchins
$51,891 in investment advisory and administration fees. For the year ended
November 30, 1997, Mitchell Hutchins voluntarily waived $13,206 in investment
advisory and administration fees from the Fund.

DISTRIBUTION PLANS

         Mitchell Hutchins is the distributor of the Fund's shares and has
appointed PaineWebber as the exclusive dealer for the sale of those shares.
Under separate plans of distribution pertaining to Class A, Class B and Class C
shares, the Fund pays Mitchell Hutchins monthly service fees at an 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 an annual rate of 0.75% and 0.50% of the
average daily net assets of Class B shares and Class C shares, respectively. At
November 30, 1997, the Fund owed Mitchell Hutchins $51,695 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 deferred sales charges paid by the shareholders upon certain
redemptions of Class A, Class B and Class C shares. Mitchell Hutchins has
informed the Fund that for the year ended November 30, 1997, it earned $260,296
in sales charges.

SECURITY LENDING

         The 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 securities in an amount at least equal to the market value of the
securities loaned, plus accrued interest, determined on a daily basis and
adjusted accordingly. The Fund will retain record ownership of loaned securities
to exercise certain beneficial rights, however, the Fund may bear the risk of
delay in recovery of, or even loss of rights in, the securities loaned should
the borrower fail financially. The Fund receives compensation, which is included
in interest 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
borrower plus reasonable administrative and custody fees. The Fund's lending

agent is PaineWebber, who received $4,254 from the Fund for the year ended
November 30, 1997.

         As of November 30, 1997, the Fund's custodian held cash and/or cash
equivalents having an aggregate value of $7,376,250 as collateral for portfolio
securities loaned having a market value of $7,136,252.

TRANSFER AGENCY SERVICE FEES

         Prior to August 1, 1997 the 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 through July 31, 1997. For these services
for the period ended July 31, 1997, PaineWebber earned $10,503 in transfer
agency service fees from the Fund.

         Subsequent to August 1, 1997, PaineWebber provides transfer agency
related services to the 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 Fund.

INVESTMENTS IN SECURITIES

         For federal income tax purposes, the cost of securities owned at
November 30, 1997, was substantially the same as the cost of securities for
financial statement purposes.

NOTES TO FINANCIAL STATEMENTS

At November 30, 1997, the components of the net unrealized appreciation of
investments were as follows:

Gross appreciation (investments having an excess of
  value over cost) ...........................................      $ 3,420,807
Gross depreciation (investments having an excess of
  cost over value) ...........................................       (1,306,315)
                                                                    -----------
Net unrealized appreciation of investments ...................      $ 2,114,492
                                                                    ===========

For the year ended November 30, 1997, total aggregate purchases and sales of
portfolio securities, excluding short-term securities, were as follows:

Purchases ....................................................      $111,847,753
Sales ........................................................      $ 92,320,255

FEDERAL TAX STATUS

         The Fund intends to distribute all of its taxable income and to comply
with the other requirements of the Internal Revenue Code applicable to regulated
investment companies. Accordingly, no provision for federal income taxes is

required. In addition, by distributing during each calendar year substantially
all of its net investment income, capital gains and certain other amounts, if
any, the Fund intends not to be subject to a federal excise tax.

         At November 30, 1997, the Fund had a net capital loss carryforward of
$6,682,965 that will expire between November 30, 2002 and November 30, 2004.
This loss carryforward is available as a reduction, to the extent provided in
the regulations, of future net realized capital gains. To the extent that such
losses are used to offset future net realized capital gains, it is probable
these gains will not be distributed.

         To reflect reclassifications arising from permanent "book/tax"
differences for the year ended November 30, 1997, undistributed/distributions in
excess of net investment income was increased by $414,891, accumulated net
realized gains/losses was decreased by $403,175. and beneficial interest was
decreased by $11,716. Permanent book/tax differences are primarily attributable
to foreign currency gains/losses.

SHARES OF BENEFICIAL INTEREST

         There is an unlimited amount of $0.001 par value shares of beneficial
interest authorized. Transactions in shares of beneficial interest were as

(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each period reported, reinvestment of all dividends and other
    distributions 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 each class would be lower if sales
    charges were included. Total investment return for periods of less than one

    year has not been annualized.

(2) During the year ended November 30, 1997 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 would have been
    1.66% for Class A, 2.45% for Class B and 2.18% for Class C shares.

*   Annualized

(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each period reported, reinvestment of all dividends and other
    distributions 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 each class would be lower if sales
    charges were included. Total investment return for periods of less than one
    year has not been annualized.

(2) During the year ended November 30, 1997 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 would have been
    1.66% for Class A, 2.45% for Class B and 2.18% for Class C shares.

PAINEWEBBER STRATEGIC INCOME FUND

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of

PaineWebber Strategic Income Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of PaineWebber Strategic Income Fund
(the "Fund") at November 30, 1997, the results of its operations for the year
ended November 30, 1997, the changes in its net assets for the year ended
November 30, 1997 and the period February 1, 1996 through November 30, 1996, and
the financial highlights for each of the periods indicated, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion of these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at November 30, 1997 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

PAINEWEBBER STRATEGIC INCOME FUND

TAX INFORMATION

         We are required by Subchapter M of the Internal Revenue Code of 1986,
as amended, to advise you within 60 days of the Fund's fiscal period end
(November 30, 1997), as to the federal tax status of distributions received by
shareholders during such fiscal year. Accordingly, we are advising you that all
of the distributions paid by the Fund during the period were derived from net
investment income and are 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 reporting.

         Because the Fund's fiscal year is not the calendar year, another
notification will be sent in respect of calendar year 1997. The second
notification, which reflects the amount to be used by calendar year taxpayers on
their federal income tax returns, will be made in conjunction with Form 1099 DIV
and will be mailed in January 1998. Shareholders are advised to consult their

own tax advisers with respect to the tax consequences of their investment in the
Fund.

                                                                              23
