PAINEWEBBER STRATEGIC INCOME FUND                                  ANNUAL REPORT


PERFORMANCE AT A GLANCE
- --------------------------------------------------------------------------------

Comparison of the change of a $10,000 investment in PaineWebber Strategic Income
Fund  (Classes A, B and C) and the Lehman  Brothers  Aggregate  Bond Index,  the
Salomon  Smith Barney  World  Government  Bond Index and the Merrill  Lynch High
Yield Master Index from February 7, 1994 through November 30, 1999


The graph depicts the performance of PaineWebber  Strategic Income Fund (Classes
A, B and C) versus the Lehman Brothers  Aggregate Bond Index,  the Salomon Smith
Barney  World  Government  Bond Index and the  Merrill  Lynch High Yield  Master
Index.  It  is  important  to  note  PaineWebber  Strategic  Income  Fund  is  a
professionally  managed  mutual  fund while the Indices  are not  available  for
investment and are unmanaged.  The comparison is shown for illustrative purposes
only.

Past performance is no guarantee of future  performance.  The performance of the
classes  varies  based  on  differences  in  sales  charges  and  fees  paid  by
shareholders  investing  in  different  classes.  Class Y shares  are not  shown
because they were first issued at a later date.

Dear Shareholder,

     We are  pleased to  present  you with the  annual  report  for  PaineWebber
Strategic Income Fund (the "Fund") for the fiscal year ended November 30, 1999.

MARKET REVIEW
- --------------------------------------------------------------------------------

[GRAPHIC]

     Interest rates rose in the United States as the economy continued to expand
more briskly than anticipated.  The Federal Reserve (the Fed) raised the Federal
Funds rate three  times  during the fiscal  year,  by 25 basis  points each time
(bps; a basis point equals one  one-hundredth  of one percent).  These increases
reversed the 75 bps  reduction  engineered  in late 1998 to stave off the global
financial  crisis.  The 30-year  Treasury  bond's yield  increased from 5.07% on
November 30, 1998 to 6.29% on November 30, 1999,  one of its worst  performances
ever. At the same time, short-term rates rose significantly, with 90-day T-bills
moving from a yield  equivalent of 4.49% at the beginning of the fiscal year, to
a yield of 5.30% at its close.

     Mortgage "spreads" to Treasurys  narrowed for most of the year,  benefiting
portfolios  with mortgage  exposure.  (The spread is the  difference in yield or
income that securities must pay to compensate for their greater risk relative to
U.S.  Treasurys.)  High-yield  bonds achieved  modest gains for the fiscal year,
gaining  1.81% as  measured  by the CS  First  Boston  High  Yield  Bond  Index.
Corporate bonds suffered from oversupply and buyers' Y2K worries, and lost 1.14%
as measured by the Lehman  Brothers  Corporate  Bond Index.

     Interest  rates also rose  during the fiscal  year in  developed  countries
around the  world,  in  response  to  increasing  economic  activity  and higher
commodity  prices.  Emerging  market bonds were the best  performers  last year,
benefiting from a return of investor  confidence after the sharp sell-off in the
wake of the  Russian  debt  crisis  of 1998.

                                    [GRAPH]

A sooner-than-expected  return to economic stability and rising commodity prices
contributed to their strength, although spreads to U.S. Treasurys did not return
to their pre-crisis levels.

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

[GRAPHIC]

     The Fund  allocates  assets  among  three main  sectors of the global  bond
market--U.S.  government/investment  grade  bonds,  U.S.  high-yield  bonds  and
non-U.S. bonds--and shifts emphasis among them as conditions warrant.

     Through the first half of the fiscal year, the Fund  maintained  relatively
high allocations to the U.S.  high-yield and  investment-grade  bond sectors. In
August 1999,  spreads in the high-yield  sector  widened as investors  withdrew,
fearful of potential Y2K  problems.  In response,  we began  reducing the Fund's
high-yield allocation and increased its allocation to the U.S.  investment-grade
sector. The high-yield allocation reached a low of 38.3% in October.

     By the  end of the  fiscal  year we had  increased  the  Fund's  high-yield
allocation to 38.6%,  in an effort to participate  in the "January  effect" that
has resulted in  high-yield  bond prices rising during the first quarter of each
of the last four years.  We believe  technical  factors  could make  January and
February of 2000 very positive months for the high-yield market.

     At fiscal year-end,  the Fund's investment grade allocation stood at 42.9%,
of  which  36.9%  was  allocated  to  mortgage-backed  securities  and  6.0%  to
investment-grade  corporate bonds. The Fund remained underweighted in the global
markets.

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

[GRAPHIC]

     In the first half of 2000,  we expect an active Fed and rising rates across
the yield curve.  We look for moderating  economic  growth in the second half of
the year,  and believe  interest rates will recede in response to slowing growth
and the absence of real inflationary pressure. In this environment, we think the
spread sectors--mortgages,  agencies,  investment-grade corporate and high-yield
bonds--will  perform well. We think the mortgage market could see further spread
narrowing in certain sub-sectors.

* Weightings represent percentages of net assets as of November 30, 1999, unless
indicated   otherwise.   The  Fund's  portfolio  is  actively  managed  and  its
composition will vary over time.

ANNUAL REPORT

     Looking to 2000 and  beyond,  we believe the next big  opportunity  for the
Fund will be in the  global  markets,  where we expect  rates to rise and become
more  attractive  relative to rates in the U.S. If this  occurs,  we  anticipate
increasing  our  global  allocation.  The Fund has  increased  its  exposure  to
European  markets by investing in the euro  currency.  We believe that over time
the euro will strengthen against the dollar and enhance the Fund's return.

     Our  ultimate  objective  in  managing  your  investments  is to  help  you
successfully  meet your financial goals. We thank you for your continued support
and welcome any comments or questions  you may have.  For a QUARTERLY  REVIEW on

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
   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  Includes foreign exchange gain distributions, if any.

Note:  The Fund offers Class Y shares to a limited group of eligible  investors,
including  participants  in certain  investment  programs  that are sponsored by
PaineWebber  and may  invest in  PaineWebber  mutual  funds.  For the year ended
November 30, 1999, and since  inception,  February 17, 1998 through November 30,
1999, Class Y shares had a total return of 1.91% and 0.86%, respectively.  Class
Y shares do not have initial or  contingent  deferred  sales  charges or ongoing
distribution and service fees.

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  ("Trust"),  which was organized under  Massachusetts  law by a
Declaration of Trust dated  December 3, 1992 and registered  with the Securities
and Exchange Commission under the Investment Company Act of 1940, as amended, as
an open-end management investment company. The Fund seeks high levels of current
income and,  secondarily,  capital  appreciation  by allocating its  investments
among  three bond  market  categories:  U.S.  government  and  investment  grade
corporate  bonds;  U.S. high yield,  high risk corporate  bonds; and foreign and
emerging  market  bonds.  Costs  incurred  by the  Fund in  connection  with its
organization  have been deferred and amortized  using the  straight-line  method
over a sixty month period from the commencement of operations.

     Currently,  the Fund  offers  Class A, Class B, Class C and Class Y shares.
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 their 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--The  Fund calculates its net asset value based on
the current market value for its portfolio securities. The Fund normally obtains
market value for its 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
comparable 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
valued 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   Incorporated
("PaineWebber")  and  investment  adviser and  administrator  of the Fund.  If a
market  value  is  not  available  from  an  independent  pricing  source  for a
particular security, that security is valued at fair value as determined in good
faith by or under the direction of the Fund's board of trustees  (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 the board determines that this does not represent
fair value. 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 Fund's board.

                                       15

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  book  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;  and (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 contacts 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.

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

NOTES TO FINANCIAL STATEMENTS

     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  contact is the contract
value. The Fund primarily uses financial futures contracts to manage duration or
for hedging  purposes  and not for  leverage.  However,  imperfect  correlations
between  futures  contracts  and  portfolio  securities  being hedged or, market
disruptions, do not normally permit full control of these risks at all times.

     WRITTEN OPTIONS--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 the
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.

     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.  Mortgage  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
risk of  prepayments.  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

are greater with respect to  securities  of issuers  located in emerging  market
countries in which the Fund is authorized to invest.

INVESTMENT ADVISER AND ADMINISTRATOR

     The Trust's  board 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 accrued  daily and paid
monthly,  at an annual rate of 0.75% of the Fund's average daily net assets.  At
November 30, 1999 the Fund owed Mitchell Hutchins $66,521 in investment advisory
and administration fees. For the year ended November 30, 1999, Mitchell Hutchins
voluntarily waived $2,468 in investment  advisory and  administration  fees from
the Fund.  Mitchell  Hutchins  also waived $31 of its  investment  advisory  and
administration  fees in connection with the Fund's investment of cash collateral
from security lending in the Mitchell Hutchins Private Money Market Fund LLC.

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 the 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, 1999,

deferred  sales charges paid by the  shareholders  upon certain  redemptions  of
Class B and Class C shares. Mitchell Hutchins has informed the Fund that for the
year ended  November 30, 1999,  it earned  $200,983 in sales  charges.

  SECURITY LENDING

     The Fund may lend  securities up to 331/3% of its total assets to qualified
institutions.  The loans  are  secured  at all times by cash or U.S.  government
securities  or  irrevocable  letters  of  credit  that meet  certain  guidelines
established  by  Mitchell  Hutchins,  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 regain 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. For the
year ended November 30, 1999, the Fund earned $1,178 for

At November 30, 1999, the Fund owed  PaineWebber $51 for security  lending fees.
There were no securities  out on loan on November 30, 1999.

BANK LINE OF CREDIT

     The 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  settlement of sales or purchases 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 a  commitment  fee,  pro rata,  based on the relative
asset  size of the funds in 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, 1999, the Fund did not borrow under the Facility.

TRANSFER AGENCY RELATED SERVICE FEES

     PaineWebber  provides  certain 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. For
the year  ended  November  30,  1999,  PaineWebber  received  from  PFPC,  Inc.,
approximately  42% of the  total  transfer  agency  and  related  services  fees
collected by PFPC.

INVESTMENTS IN SECURITIES

     For federal income tax purposes,  the cost of securities  owned at November
30, 1999 was  substantially  the same as the cost of  securities  for  financial

FEDERAL INCOME 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,  1999,  the Fund has a net capital  loss  carryforward  of
$10,029,452  that will expire  between  November 30, 2002 and November 30, 2007.
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, 1999,  undistributed  net investment  income was
increased by $60,247,  accumulated net realized losses was decreased by $582,283
and  beneficial   interest  was  decreased  by  $642,530.   Permanent   book/tax
differences are primarily attributable to foreign currency gains/losses.

    distributions, if any, at net asset value on the payable dates and a sale at
    net asset value on the last day of each year reported. The figures do not

REPORT OF PRICEWATERHOUSECOOPERS LLP
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, 1999, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended 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 on 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, 1999 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.

     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 1999. 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 2000. Shareholders are advised to consult their
own tax advisors with respect to the tax consequences of their investment in the
Fund.
