PROSPECTUS
    
                       11,289,500 SHARES OF COMMON STOCK
 
                       THE ZWEIG TOTAL RETURN FUND, INC.
                   ISSUABLE UPON EXERCISE OF NON-TRANSFERABLE
              RIGHTS TO SUBSCRIBE FOR SUCH SHARES OF COMMON STOCK
                            ------------------------
 
     The Zweig Total Return Fund, Inc. (the "Fund") is issuing to its
shareholders of record ("Record Date Shareholders") as of the close of business
on April 15, 1998 (the "Record Date") non-transferable rights (the "Rights").
These rights entitle their holders to subscribe for up to an aggregate of
11,289,500 shares (the "Shares") of the Fund's Common Stock, par value $0.001
per share (the "Common Stock") at the rate of one Share of Common Stock for
every seven Rights held (the "Offer"). Record Date Shareholders will receive one
non-transferable Right for each whole share of Common Stock held on the Record
Date. Record Date Shareholders who fully exercise their Rights will be entitled
to subscribe for additional shares of Common Stock pursuant to an
over-subscription privilege described in this Prospectus (the "Over-
Subscription Privilege"). The Fund may increase the number of shares of Common
Stock subject to subscription by up to 25% of the Shares, or up to an additional
2,822,375 shares of Common Stock, for an aggregate total of 14,111,875 Shares.
Fractional Shares will not be issued upon the exercise of Rights. The Rights are
non-transferable and, therefore, may not be purchased or sold. The Rights will
not be admitted for trading on the New York Stock Exchange (the "NYSE"), the
Pacific Exchange (the "PCX") or any other exchange. See "The Offer." THE
SUBSCRIPTION PRICE PER SHARE (THE "SUBSCRIPTION PRICE") WILL BE 95% OF THE
AVERAGE OF THE LAST REPORTED SALES PRICE OF A SHARE OF THE FUND'S COMMON STOCK
ON THE NYSE ON MAY 8, 1998 (THE "PRICING DATE") AND THE FOUR PRECEDING BUSINESS
DAYS.
     THE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON MAY 8, 1998
UNLESS EXTENDED AS DESCRIBED HEREIN (THE "EXPIRATION DATE").
   
     The Fund announced the Offer after the close of trading on the NYSE on
March 5, 1998. The Fund's Common Stock trades on the NYSE and PCX under the
symbol "ZTR." Shares issued upon the exercise of Rights and the
Over-Subscription Privilege will be listed for trading on the NYSE and PCX,
subject to notice of issuance. The net asset value per share of the Fund's
Common Stock at the close of business on March 5, 1998 and April 13, 1998 were
$8.64 and $8.75, respectively, and the last reported sales price of a share of
the Fund's Common Stock on the NYSE on those dates were $9.4375 and $9.3125,
respectively.
    
     The Fund is a diversified, closed-end management investment company. Its
investment objective is to seek the highest total return, consisting of capital
appreciation and current income, consistent with the preservation of capital.
The Fund will invest up to 65% of its total assets in U.S. Government
Securities, non-convertible debt securities of domestic issuers rated among the
two highest rating categories of either Moody's Investors Services, Inc. or
Standard & Poor's Corporation (or of comparable quality), and certain Foreign
Government Securities, and up to 35% of its total assets in equity securities.
The Fund may, however, under certain circumstances, invest up to 75% of its
total assets in equity securities. The extent of the Fund's investment in debt
and equity securities will be determined primarily on the basis of market timing
techniques developed by Dr. Martin E. Zweig, the President of the Fund's
investment adviser, Zweig Total Return Advisors, Inc. (the "Investment
Adviser"), and his staff. Dr. Zweig is the majority shareholder of the
Investment Adviser and has been engaged in the business of providing investment
advisory services for over 25 years. While the Investment Adviser seeks to
reduce the risks associated with investing in debt and equity securities by
using these techniques, the risk of investment in debt and equity securities
cannot be eliminated. See "Investment Objective and Policies." No assurance can
be given that the Fund's investment objective will be realized. The Fund's
administrator is Zweig/Glaser Advisers (the "Administrator"). The Fund's
Investment Adviser as well as the Administrator will benefit from the Offer. See
"Management of the Fund."

(Continued from cover)
 
     Upon the completion of the Offer, Record Date Shareholders who do not fully
exercise their Rights will own a smaller proportional interest in the Fund than
they owned prior to the Offer. In addition, because the Subscription Price may
be less than the then current net asset value per share as of the Pricing Date,
the Offer may result in an immediate dilution of the net asset value per share
for all shareholders. Although it is not possible to state precisely the amount
of such decrease in net asset value per share, if any, because it is not known
how many Shares will be subscribed for, what the net asset value or market price
of the Common Stock will be on the Pricing Date or what the Subscription Price
will be, such dilution could be minimal or substantial. Any such dilution will
disproportionately affect non-exercising shareholders. See "The Offer" and "Risk
Factors and Special Considerations." Except as described in this Prospectus,
Record Date Shareholders will have no right to rescind their subscriptions after
receipt of their payment for Shares by the Subscription Agent.
 
   
     This Prospectus sets forth concisely the information about the Fund that a
prospective investor ought to know before investing. Investors are advised to
read this Prospectus and retain it for future reference. A Statement of
Additional Information, dated April 14, 1998 (the "SAI"), containing additional
information about the Fund, has been filed with the Securities and Exchange
Commission (the "Commission") and is incorporated by reference in its entirety
into this Prospectus.
    
 
     Shareholders may obtain a copy of the SAI from, and should direct all
questions and inquires relating to the Offer to, the Fund's Information Agent,
Georgeson & Company Inc. Banks and Brokers should call (212) 440-9800 collect
and all other shareholders should call (800) 223-2064. The address of the Fund
is 900 Third Avenue, New York, New York 10022, and its telephone number is (212)
451-1100. The Commission maintains a world wide web site at http://www.sec.gov
that contains the SAI and other information regarding the Fund.

                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by reference to the more
detailed information included elsewhere in this Prospectus. Unless otherwise
indicated, the information in this Prospectus assumes that the allowable
increase of 25% of the Shares offered hereby pursuant to the Over-Subscription
Privilege will not occur.
 
                                    THE FUND
 
   
     The Zweig Total Return Fund, Inc. (the "Fund") is a diversified, closed-end
management investment company registered under the Investment Company Act of
1940, as amended (the "1940 Act"). The Fund commenced operations in September
1988. The Fund's investment objective is to seek the highest total return,
consisting of capital appreciation and current income, consistent with the
preservation of capital. The Fund will invest up to 65% of its total assets in
U.S. Government Securities, non-convertible debt securities of domestic issuers
rated among the two highest rating categories of either Moody's Investors
Services, Inc. or Standard & Poor's Corporation (or of comparable quality), and
certain Foreign Government Securities, and up to 35% of its total assets in
equity securities. The Fund may, however, under certain circumstances, invest up
to 75% of its total assets in equity securities. The extent of the Fund's
investment in debt and equity securities will be determined primarily on the
basis of market timing techniques developed by Dr. Martin E. Zweig, the
President of the Fund's investment adviser, Zweig Total Return Advisors, Inc.
(the "Investment Adviser"), and his staff. While the Investment Adviser seeks to
reduce the risks associated with investing in debt and equity securities by
using these techniques, the risk of investment in debt and equity securities
cannot be eliminated. The Fund's outstanding Common Stock, par value $.001 per
share (the "Common Stock") is listed and traded on the New York Stock Exchange
(the "NYSE") and the Pacific Exchange ("PCX"). The average weekly trading volume
of the Common Stock on the NYSE during the year ended December 31, 1997 was
673,446 shares. As of April 13, 1998, the net assets of the Fund were
approximately $691,600,000.
    
 
     The President and majority shareholder of the Investment Adviser is Dr.
Martin E. Zweig, who has been engaged in the business of providing investment
advisory services for over 25 years. Zweig/Glaser Advisers (the "Administrator")
serves as the Fund's administrator. The Fund pays the Investment Adviser an
investment advisory fee computed at the annual rate of 0.70% of the Fund's
average daily net assets. The Fund pays the Administrator an administrative fee
computed at the annual rate of 0.13% of the Fund's average daily net assets. See
"Management of the Fund."
 
                               TERMS OF THE OFFER
 
     The Fund is issuing to its shareholders of record ("Record Date
Shareholders") as of the close of business on April 15, 1998 (the "Record Date")
non-transferable rights (the "Rights") to subscribe for up to an aggregate of
11,289,500 shares of Common Stock (the "Shares") of the Fund. The Fund may
increase the number of shares of Common Stock subject to subscription by up to
25% of the Shares, or up to an additional 2,822,375 shares of Common Stock, for
an aggregate total of 14,111,875 shares. Each Record Date Shareholder is being
issued one Right for each whole share of Common Stock owned on the Record Date.
The Rights entitle the holders thereof to subscribe for one Share for every
seven Rights held (the "Offer").
 
     Fractional shares will not be issued upon the exercise of Rights. If a
Record Date Shareholder's total ownership is fewer than seven shares, such
Record Date Shareholder may subscribe for one Share.
 
     Rights may be exercised at any time during the Subscription Period, which
commences on April 15, 1998 and ends at 5:00 p.m. New York City time, on May 8,
1998, unless extended by the Fund until 5:00 p.m., New York City time to a date
not later than May 15, 1998 (such date, as it may be extended, is referred to in
this Prospectus as the "Expiration Date"). A Record Date Shareholder's right to
acquire during the Subscription Period at the Subscription Price (as described
below) one additional Share for every seven Rights held is hereinafter referred
to as the "Primary Subscription." The Rights are evidenced by subscription
certificates (the "Subscription Certificates"), which will be mailed to Record
Date Shareholders, except as discussed in "The Offer -- Foreign Restrictions."
 
                                        3
<PAGE>   8
 
     The Subscription Price per share (the "Subscription Price") will be 95% of
the average of the last reported sales prices of a share of the Fund's Common
Stock on the NYSE on May 8, 1998 (the "Pricing Date") and the four preceding
business days. Since the Expiration Date and the Pricing Date are each May 8,
1998, Record Date Shareholders who choose to exercise their Rights will not know
at the time of exercise the Subscription Price for Shares acquired pursuant to
such exercise. Record Date Shareholders will have no right to rescind a purchase
after receipt of their payment for Shares by the Fund's subscription agent,
State Street Bank & Trust Co. (the "Subscription Agent"). There is no minimum
number of Rights that must be exercised in order for the Offer to close.
 
     Pursuant to the over-subscription privilege (the "Over-Subscription
Privilege"), any Record Date Shareholder who fully exercises all Rights issued
to such Record Date Shareholder in the Primary Subscription (other than those
Rights that cannot be exercised because they represent the right to acquire less
than one Share) will be entitled to subscribe for additional Shares at the
Subscription Price. Shares available, if any, pursuant to the Over-Subscription
Privilege are subject to allotment and may be subject to increase, as is more
fully discussed under "The Offer -- Over-Subscription Privilege." For purposes
of determining the maximum number of Shares a Record Date Shareholder may
acquire pursuant to the Offer, Record Date Shareholders whose Shares are held of
record by Cede & Co. Inc. ("Cede") or by any other depository or nominee will be
deemed to be the holders of the Rights that are issued to Cede or such other
depository or nominee on their behalf.
 
     The Rights are non-transferable. Therefore, only the underlying Shares will
be listed for trading on the NYSE, PCX or any other exchange.
 
                              PURPOSE OF THE OFFER
 
     The Board of Directors of the Fund has determined that it would be in the
best interests of the Fund and its shareholders to increase the assets of the
Fund available for investment, thereby enabling the Fund to more fully take
advantage of investment opportunities consistent with the Fund's investment
objective. The Fund's Board of Directors has voted unanimously to approve the
terms of the Offer as set forth in this Prospectus.
 
     In reaching its decision, the Board of Directors considered, among other
things, advice by the Investment Adviser that new funds would allow the Fund
additional flexibility to capitalize on available investment opportunities
without the necessity of having to sell existing portfolio securities that the
Investment Adviser believes should be held. Proceeds from the Offer will allow
the Investment Adviser to better take advantage of such existing and future
investment opportunities.
 
     The Board of Directors also considered that the Offer would provide
shareholders with an opportunity to purchase additional shares of the Fund below
its market price. The Board of Directors also believes that a well-subscribed
rights offering may result in certain economies of scale which could reduce the
Fund's expense ratio in future years. Finally, the Board of Directors considered
that, because the Subscription Price per Share may be less than the net asset
value per share on the Pricing Date, the Offer may result in dilution of the net
asset value per share. The Board of Directors believes that the factors in favor
of the Offer outweigh this possible dilution. See "Risk Factors and Special
Considerations -- Dilution and Effect of Non-Participation in the Offer."
 
     The Fund's Investment Adviser and Administrator will benefit from the Offer
because their fees are based on the average net assets of the Fund. It is not
possible to state precisely the amount of additional compensation the Investment
Adviser or Administrator will receive as a result of the Offer because it is not
known how many Shares will be subscribed for and because the proceeds of the
Offer will be invested in additional portfolio securities, which will fluctuate
in value. See "Management of the Fund."

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
     The following summarizes certain matters that should be considered, among
others, in connection with the Offer. This Prospectus contains certain
forward-looking statements. Actual results could differ materially from those
projected in the forward-looking statements as a result of certain uncertainties
set forth below and elsewhere in this Prospectus.
 
   
Dilution -- Net Asset Value
  and Non-Participation
  in the Offer.............  Record Date Shareholders who do not fully exercise
                             their Rights will, upon the completion of the
                             Offer, own a smaller proportional interest in the
                             Fund than they owned prior to the Offer. In
                             addition, an immediate dilution of the net asset
                             value per share may be experienced by all
                             shareholders as a result of the Offer because the
                             Subscription Price may be less than the then
                             current net asset value per share, and the number
                             of shares outstanding after the Offer may increase
                             in greater percentage than the increase in the size
                             of the Fund's assets. Although it is not possible
                             to state precisely the amount of such decrease in
                             net asset value per share, if any, because it is
                             not known at this time what the Subscription Price
                             will be, what the net asset value per share will be
                             on the Expiration Date, or what proportion of the
                             Shares will be subscribed for, such dilution could
                             be minimal or substantial. For example, assuming
                             (i) all Rights are exercised, (ii) the Fund's net
                             asset value on the Expiration Date is $8.75 per
                             share (the net asset value per share on
    
 
                                        5
<PAGE>   10
 
   
                             April 13, 1998), and (iii) the Subscription Price
                             is $8.85 per share (95% of the last reported sale
                             price per share on the NYSE on April 13, 1998),
                             then the Fund's net asset value per share would be
                             reduced by approximately $0.04 per share or 0.46%.
    
 
Certain Investment
Strategies.................  The extent of the Fund's investment in debt and
                             equity securities will be determined primarily on
                             the basis of market timing techniques developed by
                             Dr. Martin E. Zweig, the President of the Fund's
                             Investment Adviser, and his staff. While the
                             Investment Adviser seeks to reduce the risks
                             associated with investing in debt and equity
                             securities by using these techniques, the risk of
                             investment in debt and equity securities cannot be
                             eliminated. There is no assurance that these market
                             timing techniques will provide protection from the
                             risks of debt or equity investment, enable the Fund
                             to be invested consistent with the major trends of
                             the markets or enable the Fund to achieve its
                             investment objective. See "Investment Objective and
                             Policies -- Investment Objective." In addition,
                             although the Investment Adviser believes that the
                             special investment methods discussed in this
                             Prospectus under "Special Investment Methods"
                             (including purchasing and selling interest rate,
                             stock index and other futures contracts and
                             purchasing options on such futures; purchasing and
                             writing listed put and call security options and
                             options on stock indexes; short sales of
                             securities; borrowing from banks to purchase
                             securities; investing in securities of closed-end
                             investment companies and foreign issuers; lending
                             portfolio securities to brokers, dealers, banks or
                             other recognized institutional borrowers of
                             securities; entering into repurchase or reverse
                             repurchase agreements; and purchasing when-issued
                             and delayed-delivery securities) will further the
                             Fund's investment objective and reduce losses that
                             might otherwise occur during a time of general
                             decline in debt or equity security prices, no
                             assurance can be given that these investment
                             methods will achieve this result. These methods may
                             subject an investor in the Fund to greater than
                             average risks and costs.
 
Unrealized Appreciation....  As of December 31, 1997, there was $50,238,438 or
                             approximately $0.64 per share of net unrealized
                             appreciation in the Fund's net assets of
                             $677,133,054; if realized and distributed, or
                             deemed distributed, such gains would, in general,
                             be taxable to shareholders, including holders at
                             that time of Shares acquired upon the exercise of
                             Rights. See "Taxation."
 
Discount From
  Net Asset Value..........  The Fund's shares of Common Stock have traded in
                             the market above, at and below net asset value
                             since the commencement of the Fund's operations in
                             September 1988. During the past seven years, the
                             Fund's shares have generally traded in the market
                             at a premium above net asset value; however, the
                             Fund cannot predict whether the Fund's Common Stock
                             will in the future trade at a premium to or
                             discount from net asset value. The risk of the
                             Common Stock trading at a discount is a risk
                             separate from a decline in the Fund's net asset
                             value. See "Market Price and Net Asset Value
                             Information" in this Prospectus and "Net Asset
                             Value" in the Statement of Additional Information
                             (the "SAI").
 
Distributions..............  The Fund's policy is to make monthly distributions
                             equal to 0.83% of its net asset value (10% on an
                             annualized basis). If, for any monthly
                             distribution, net investment income and net
                             realized short-term capital gains are less than the
                             amount of the distribution, the difference will be
 
                                        6
<PAGE>   11
 
                             distributed from the Fund's assets. The Fund's
                             final distribution for each calendar year will
                             include any remaining net investment income and net
                             realized short-term capital gains deemed, for
                             Federal income tax purposes, undistributed during
                             the year, as well as all net long-term capital
                             gains realized during the year. If, for any
                             calendar year, the total distributions exceed net
                             investment income and net realized capital gains,
                             the excess, distributed from the Fund's assets,
                             will generally be treated as a tax-free return of
                             capital (up to the amount of the shareholder's tax
                             basis in his or her shares). The amount treated as
                             a tax-free return of capital will reduce a
                             shareholder's adjusted basis in his or her shares,
                             thereby increasing his or her potential gain or
                             reducing his or her potential loss on the sale of
                             his or her shares. Such excess, however, will be
                             treated as ordinary dividend income up to the
                             amount of the Fund's current and accumulated
                             earnings and profits. Pursuant to the requirements
                             of the 1940 Act and other applicable laws, a notice
                             will accompany each monthly distribution with
                             respect to the estimated source of the distribution
                             made. Such distribution policy may, under certain
                             circumstances, have certain adverse consequences to
                             the Fund and its shareholders. In the event the
                             Fund distributes amounts in excess of its net
                             investment income and net realized capital gains,
                             such distributions will decrease the Fund's total
                             assets and, therefore, have the likely effect of
                             increasing the Fund's expense ratio. In addition,
                             in order to make such distributions, the Fund may
                             have to sell a portion of its investment portfolio
                             at a time when independent investment judgment
                             might not dictate such action. Shares purchased
                             pursuant to the Offer will be issued after the
                             record date for the monthly distribution declared
                             in May, and, accordingly, the Fund will not pay a
                             monthly distribution with respect to such Shares
                             until the distribution to be declared and paid in
                             June.
 
Anti-takeover Provisions...  The Fund has provisions in its Articles of
                             Incorporation and By-Laws that may have the effect
                             of limiting the ability of other entities or
                             persons to acquire control of the Fund, to cause it
                             to engage in certain transactions or to modify its
                             structure. The Board of Directors is divided into
                             three classes. At the annual meeting of
                             shareholders each year, the term of one class will
                             expire and directors will be elected to serve in
                             that class for terms of three years. This provision
                             could delay for up to two years the replacement of
                             a majority of the Board of Directors.
 
Year 2000 Preparedness.....  Because computers were designed only using two
                             fields to indicate the year, at midnight December
                             31, 1999, computers will be unable to recognize
                             that January 1 is the year 2000. The major systems
                             that would impact the Fund with respect to the year
                             2000 are those of the transfer agent and custodian.
                             The Fund has been advised in writing by both the
                             transfer agent and custodian that they are working
                             to fix, and expect to have fixed in time, all of
                             the issues relating to the year 2000. While
                             management of the Fund will continue to monitor the
                             progress of the transfer agent and custodian in
                             solving the year 2000 problem, no assurance can be
                             given that their systems will be fixed on time, or
                             what the magnitude of the problems would be if such
                             systems are not fixed.

- ---------------
(1) The Fund has agreed to pay the Dealer Manager, and other broker-dealers
    (including Zweig Securities Corp.) soliciting the exercise of Rights,
    solicitation fees equal to 2.50% of the Subscription Price per Share for
    each Share issued pursuant to the exercise of the Rights and the
    Over-Subscription Privilege. The Fund has also agreed to pay the Dealer
    Manager a fee for financial advisory and marketing services in connection
    with the Offer equal to 1.25% of the aggregate Subscription Price for the
    Shares issued pursuant to the exercise of the Rights and the
    Over-Subscription Privilege. In addition to these fees, the offering
    expenses to be incurred by the Fund in connection with the Offer are
    estimated at approximately $720,000, which includes the Fund's reimbursement
    to the Dealer Manager for out-of-pocket expenses up to $82,500, and the
    Fund's payment of a fee to each of the Subscription Agent (as defined in
    this Prospectus) and Information Agent (as defined in this Prospectus)
    estimated to be $245,000 and $42,500, respectively (which includes
    reimbursement for their out-of-pocket expenses related to the Offer). These
    fees and expenses will be charged against paid-in capital of the Fund and
    will be borne by the Fund and indirectly by all of the Fund's shareholders,
    including those who do not exercise their Rights. See "Distribution
    Arrangements."
 
(2) Fees payable under the Investment Advisory Agreement and Administration
    Agreement (as defined in this Prospectus) are calculated on the basis of the
    Fund's average net assets. "Other Expenses" have been estimated for the
    current fiscal year. See "Management of the Fund -- Investment
    Adviser; -- Investment Advisory Agreement; and -- Administrator."
 
   
(3) The indicated 1.01% expense ratio assumes that the Offer (including the
    Over-Subscription Privilege) is fully subscribed and assumes estimated net
    proceeds from the Offer of approximately $95,466,540 million (assuming an
    estimated Subscription Price of $8.85 per share). Other expenses for the
    fiscal year ended December 31, 1997 were 0.34% of the Fund's average net
    assets and include administration fees computed at the annual rate of 0.13%
    of the Fund's average net assets.
    
 
     THE FOREGOING FEE TABLE IS INTENDED TO ASSIST FUND INVESTORS IN
UNDERSTANDING THE VARIOUS COSTS AND EXPENSES THAT AN INVESTOR IN THE FUND WILL
BEAR DIRECTLY OR INDIRECTLY.
 
EXAMPLE
 
     An investor would directly or indirectly pay the following expense on a
$1,000 investment in the Fund, assuming a 5% annual return throughout the
periods:
 
<TABLE>
<CAPTION>
  ONE YEAR        THREE YEARS        FIVE YEARS        TEN YEARS
  --------        -----------        ----------        ---------

    $47               $68               $91              $156
</TABLE>
 
     This hypothetical example assumes that all dividends and other
distributions are reinvested at net asset value and that the 1.01% expense ratio
listed under Total Annual Expenses remains the same in the years shown. The
example also reflects payment of the 3.75% Sales Load on the entire $1,000
investment. The above tables and the assumption in the Example of a 5% annual
return are required by regulations of the Securities and Exchange Commission
(the "Commission") applicable to all investment companies; the assumed 5% annual
return is not a prediction of, and does not represent, the projected or actual
performance of the Fund's Shares. For a more complete description of certain of
the Fund's costs and expenses, see "Management of the Fund -- Investment
Management; -- Investment Advisory Agreement; and -- Administrator" in this
Prospectus and "Expenses" and "Portfolio Transactions and Brokerage" in the SAI.
 
     THIS EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE EXPENSES.
THE FUND'S ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

                                   THE OFFER
 
TERMS OF THE OFFER
 
     The Fund is issuing to the Record Date Shareholders the Rights to subscribe
for up to an aggregate of 11,289,500 Shares. The Fund may increase the number of
Shares subject to subscription by up to 25% of the Shares, or up to an
additional 2,822,375 shares, for an aggregate total of 14,11,875 shares. Each
Record Date Shareholder is being issued one Right for each whole share of Common
Stock owned on the Record Date. The Rights entitle the holders thereof to
subscribe for one Share for every seven Rights held (1 for 7). Fractional shares
will not be issued upon the exercise of Rights. A Record Date Shareholder whose
total ownership is fewer than seven shares of Common Stock and, accordingly,
receives fewer than seven Rights will be able to subscribe for one Share upon
the exercise of all of such Rights received and, if he or she subscribes for one
Share, may subscribe for additional Shares pursuant to the Over-Subscription
Privilege. Record Date Shareholders who, after exercising their Rights, have
remaining fewer than seven Rights will not be able to purchase a Share upon the
exercise of such Rights and will not be entitled to receive any cash in lieu
thereof, although such Record Date Shareholders may subscribe for additional
Shares pursuant to the Over-Subscription Privilege.
 
     Rights may be exercised at any time during the Subscription Period, which
commences on April 15, 1998 and ends at 5:00 p.m. New York City time, on May 8,
1998, unless extended by the Fund until 5:00 p.m., New York City time to a date
not later than May 15, 1998. See "-- Expiration of the Offer." The Rights are
evidenced by Subscription Certificates, which will be mailed to Record Date
Shareholders, except as discussed below under "Foreign Restrictions."
 
     Any Record Date Shareholder who fully exercises all Rights issued to such
shareholder in the Primary Subscription will be entitled to subscribe for
additional Shares at the Subscription Price pursuant to the terms of the
Over-Subscription Privilege, as described below. Shares available, if any,
pursuant to the Over-Subscription Privilege are subject to allotment and may be
subject to increase, as is more fully discussed below under "Over-Subscription
Privilege." For purposes of determining the maximum number of Shares a
shareholder may acquire pursuant to the Offer, Record Date Shareholders whose
Shares are held of record by Cede or by any other depository or nominee will be
deemed to be the holders of the Rights that are issued to Cede or such other
depository or nominee on their behalf.
 
PURPOSE OF THE OFFER
 
     The Board of Directors of the Fund has determined that it would be in the
best interests of the Fund and its shareholders to increase the assets of the
Fund available for investment, thereby enabling the Fund to more fully take
advantage of investment opportunities consistent with the Fund's investment
objective. The Fund's Board of Directors has voted unanimously to approve the
terms of the Offer as set forth in this Prospectus.
 
     In reaching its decision, the Board of Directors considered, among other
things, advice by the Investment Adviser that new funds would allow the Fund
additional flexibility to capitalize on available investment opportunities
without the necessity of having to sell existing portfolio securities that the
Investment Adviser believes should be held. Proceeds from the Offer will allow
the Investment Adviser to better take advantage of such existing and future
investment opportunities.
 
     The Board of Directors also considered that the Offer would provide
shareholders with an opportunity to purchase additional shares of the Fund below
its market price. The Board of Directors also believes that a well-subscribed
rights offering may result in certain economies of scale which could reduce the
Fund's expense ratio in future years. Finally, the Board of Directors considered
that, because the Subscription Price per Share may be less than the net asset
value per share on the Pricing Date, the Offer may result in dilution of the net
asset value per share. The Board of Directors believes that the factors in favor
of the Offer outweigh this possible dilution. See "Risk Factors and Special
Considerations -- Dilution-Net Asset Value and Non-Participation in the Offer."

     The Fund's Investment Adviser and Administrator will benefit from the Offer
because their fees are based on the average net assets of the Fund. It is not
possible to state precisely the amount of additional compensation the Investment
Adviser or Administrator will receive as a result of the Offer because it is not
known how many Shares will be subscribed for and because the proceeds of the
Offer will be invested in additional portfolio securities, which will fluctuate
in value. See "Management of the Fund."
 
     The Fund may, in the future and at its discretion, choose to make
additional rights offerings from time to time for a number of shares and on
terms that may or may not be similar to the Offer. Any such future rights
offerings will be made in accordance with the then applicable requirements of
the 1940 Act.
 
OVER-SUBSCRIPTION PRIVILEGE
 
     To the extent Record Date Shareholders do not exercise all of the Rights
issued to them, any underlying Shares represented by such Rights will be offered
by means of the Over-Subscription Privilege to the Record Date Shareholders who
have exercised all of the Rights issued to them and who wish to acquire more
than the number of Shares to which they are entitled. Only Record Date
Shareholders who exercise all the Rights issued to them may indicate, on the
Subscription Certificate, which they submit with respect to the exercise of the
Rights issued to them, how many Shares they desire to purchase pursuant to the
Over-Subscription Privilege. If sufficient Shares remain after completion of the
Primary Subscription, all over-subscription requests will be honored in full. If
sufficient Shares are not available to honor all over-subscription requests, the
Fund may, at the discretion of the Board of Directors, issue shares of Common
Stock up to an additional 25% of the Shares available pursuant to the Offer, or
2,822,375 additional shares of Common Stock in order to cover such
over-subscription requests. Regardless of whether the Fund issues additional
shares pursuant to the Offer and to the extent Shares are not available to honor
all over-subscription requests, the available Shares will be allocated among
those who over-subscribe based on the number of Shares owned by them in the Fund
on the Record Date. The allocation process may involve a series of allocations
in order to assure that the total number of Shares available for
over-subscription is distributed on a pro rata basis. The Fund will not offer to
sell in connection with the Offer any Shares that are not subscribed for
pursuant to the Primary Subscription or the Over-Subscription Privilege.
 
SUBSCRIPTION PRICE
 
   
     The Subscription Price for the Shares to be issued pursuant to the Offer
will be 95% of the average of the last reported sales price of a share of the
Fund's Common Stock on the NYSE on May 8, 1998 (the "Pricing Date") and the four
preceding business days. For example, if the average of the last reported sales
price on the NYSE on the Pricing Date and the four preceding business days of a
share of the Fund's Common Stock is $9.3125, the Subscription Price will be
$8.85 (95% of $9.3125). The Subscription Price may be higher or lower than the
net asset value per share.
    
 
   
     The Fund announced the Offer after the close of trading on the NYSE on
March 5, 1998. The net asset value per share of Common Stock at the close of
business on March 5, 1998 and April 13, 1998 was $8.64 and $8.75, respectively,
and the last reported sales prices of a share of the Fund's Common Stock on the
NYSE on those dates was $9.4375 and $9.3125, respectively.
    
 
EXPIRATION OF THE OFFER
 
     The Offer will expire at 5:00 p.m., New York City time, on May 8, 1998,
unless extended by the Fund until 5:00 p.m., New York City time to a date or
dates not later than May 15, 1998. The Rights will expire on the Expiration Date
and thereafter may not be exercised. Since the Expiration Date and the Pricing
Date will be the same date, Record Date Shareholders who decide to acquire
Shares in the Primary Subscription or pursuant to the Over-Subscription
Privilege will not know when they make such decision the purchase price of such
Shares. Any extension of the Offer will be followed as promptly as practicable
by announcement thereof. Such announcement shall be issued no later than 9:00
a.m., New York City time, on the next business day following the previously
scheduled Expiration Date. Without limiting the manner in which the Fund may
choose to make such announcement, the Fund will not, unless otherwise required
by law, have any obligation
 
                                       11
<PAGE>   16
 
to publish, advertise or otherwise communicate any such announcement other than
by making a release to the Dow Jones News Service or such other means of
announcement as the Fund deems appropriate.
 
METHOD OF EXERCISE OF RIGHTS
 
   
     The Subscription Certificates, which evidence the Rights, will be mailed to
Record Date Shareholders or, if a Record Date Shareholder's shares of Common
Stock are held by Cede or any other depository or nominee on their behalf, to
Cede or such depository or nominee. Rights may be exercised by filling in
completely and signing the Subscription Certificate which accompanies this
Prospectus and mailing it in the envelope provided, or otherwise delivering the
completed and signed Subscription Certificate to the Subscription Agent,
together with payment in full for the Shares at the estimated payment price (the
"Estimated Payment Price") as described below under "Payment for Shares." Rights
may also be exercised by a Record Date Shareholder contacting his or her broker,
banker or trust company, which can arrange, on his or her behalf, to guarantee
delivery of payment (using a "Notice of Guaranteed Delivery") and of a properly
completed and executed Subscription Certificate. The broker, banker or trust
company may charge a fee for this service. Fractional Shares will not be issued.
A Record Date Shareholder whose total ownership is fewer than seven shares of
Common Stock and, accordingly, receives fewer than seven Rights will be able to
subscribe for one Share upon the exercise of all of such Rights received and, if
he or she subscribes for one Share, will be able to request additional Shares
pursuant to the terms of the Offer applicable to the Over-Subscription
Privilege. Record Date Shareholders who, after exercising their Rights, have
remaining fewer than seven Rights will not be entitled to purchase a Share upon
the exercise of such Rights but will be able to request additional Shares
pursuant to the terms of the Offer applicable to the Over-Subscription
Privilege. Completed Subscription Certificates must be received by the
Subscription Agent prior to 5:00 p.m., New York City time, on the Expiration
Date (unless the guaranteed delivery procedures are complied with as described
below under "Payment for Shares") at the offices of the Subscription Agent at
the address set forth below.
    
 
     Shareholders who Are Record Owners.  Shareholders who are record owners can
choose between either option set forth under "Payment for Shares" below. If time
is of the essence, option (2), under "Payment for Shares" below, will permit
delivery of the Subscription Certificate and payment after the Expiration Date.
 
     Shareholders whose Shares Are Held By A Nominee.  Shareholders whose shares
are held by a nominee, such as a broker or trustee, must contact such nominee to
exercise their Rights. In that case, the nominee will complete the Subscription
Certificate on behalf of the investor and arrange for proper payment by one of
the methods set forth under "Payment for Shares" below.
 
     Nominees.  Nominees who hold shares of Common Stock for the account of
others must (to the extent required by applicable law) notify the beneficial
owners of such shares as soon as possible to ascertain such beneficial owners'
intentions and to obtain instructions with respect to the Rights. If the
beneficial owner so instructs, the nominee should complete the Subscription
Certificate and submit it to the Subscription Agent with the proper payment
described under "Payment for Shares" below.

PAYMENT FOR SHARES
 
     Record Date Shareholders who acquire Shares in the Primary Subscription and
pursuant to the Over-Subscription Privilege may choose between the following
methods of payment:
 
   
          (1) A Record Date Shareholder can send the Subscription Certificate
     together with payment for the Shares acquired in the Primary Subscription
     and for additional Shares subscribed for pursuant to the Over-Subscription
     Privilege to the Subscription Agent. Payment should be calculated on the
     basis of the Estimated Payment Price of $9.00 per Share for all Shares
     requested. To be accepted, such payment, together with the executed
     Subscription Certificate, must be received by the Subscription Agent at one
     of the Subscription Agent's offices at the addresses set forth above prior
     to 5:00 p.m., New York City time, on the Expiration Date. The Subscription
     Agent will deposit all checks and money orders
    
 
                                       13
<PAGE>   18
 
   
     received by it prior to the final payment date into a segregated
     interest-bearing account (which interest will be paid to the Fund) pending
     proration and distribution of the Shares. A PAYMENT PURSUANT TO THIS METHOD
     MUST BE IN UNITED STATES DOLLARS BY MONEY ORDER OR CHECK DRAWN ON A BANK
     LOCATED IN THE UNITED STATES, MUST BE PAYABLE TO THE ZWEIG TOTAL RETURN
     FUND, INC. AND MUST ACCOMPANY A PROPERLY COMPLETED AND EXECUTED
     SUBSCRIPTION CERTIFICATE FOR SUCH SUBSCRIPTION CERTIFICATE TO BE ACCEPTED.
    
 
   
          (2) Alternatively, a subscription will be accepted by the Subscription
     Agent if, prior to 5:00 p.m., New York City time, on the Expiration Date,
     the Subscription Agent has received a Notice of Guaranteed Delivery by
     facsimile (telecopy) or otherwise from a bank, a trust company, or a NYSE
     member firm guaranteeing delivery of (i) payment of the Estimated Payment
     Price of $9.00 per share for the Shares subscribed for in the Primary
     Subscription and for any additional Shares subscribed for pursuant to the
     Over-Subscription Privilege, and (ii) a properly completed and executed
     Subscription Certificate. The Subscription Agent will not honor a Notice of
     Guaranteed Delivery unless a properly completed and executed Subscription
     Certificate together with full payment is received by the Subscription
     Agent by the close of business on the third business day after the
     Expiration Date (May 13, 1998, unless the Offer is extended).
    
 
     Within eight business days following the Expiration Date (May 20, 1998,
unless the Offer is extended, the "Confirmation Date"), a confirmation will be
sent by the Subscription Agent to each subscribing Record Date Shareholder (or,
if the Record Date Shareholder's shares of Common Stock are held by Cede or any
other depository or nominee, to Cede or such depository or nominee), showing (i)
the number of Shares acquired pursuant to the Primary Subscription, (ii) the
number of Shares, if any, acquired pursuant to the Over-Subscription Privilege,
(iii) the per Share and total purchase price of the Shares, and (iv) any
additional amount payable by such Record Date Shareholder to the Fund or any
excess to be refunded by the Fund to such Record Date Shareholder, in each case
based on the Subscription Price as determined on the Pricing Date. If any Record
Date Shareholder exercises his or her right to acquire Shares pursuant to the
Over-Subscription Privilege, any such excess payment which would otherwise be
refunded to the Record Date Shareholder will be applied by the Fund toward
payment for additional Shares acquired pursuant to exercise of the
Over-Subscription Privilege. Any additional payment required from a Record Date
Shareholder must be received by the Subscription Agent within ten business days
after the Confirmation Date. Any excess payment to be refunded by the Fund to a
Record Date Shareholder will be mailed by the Subscription Agent to such Record
Date Shareholder as promptly as possible. All payments by a Record Date
Shareholder must be in United States dollars by money order or check drawn on a
bank located in the United States of America and payable to THE ZWEIG TOTAL
RETURN FUND, INC.
 
     Whichever of the two methods described above is used, issuance and delivery
of certificates for the Shares purchased are subject to collection of checks and
actual payment pursuant to any Notice of Guaranteed Delivery.
 
     RECORD DATE SHAREHOLDERS WILL HAVE NO RIGHT TO RESCIND THEIR SUBSCRIPTION
AFTER RECEIPT OF THEIR PAYMENT FOR SHARES BY THE SUBSCRIPTION AGENT, EXCEPT AS
PROVIDED BELOW UNDER "NOTICE OF NET ASSET VALUE DECLINE."
 
     If a Record Date Shareholder who acquires Shares pursuant to the Primary
Subscription or Over-Subscription Privilege does not make payment of any
additional amounts due by the tenth Business Day after the Confirmation Date,
the Fund reserves the right to take any or all of the following actions: (i)
sell such subscribed and unpaid-for Shares to other Record Date Shareholders,
(ii) apply any payment actually received by it toward the purchase of the
greatest whole number of Shares which could be acquired by such holder upon
exercise of the Primary Subscription or Over-Subscription Privilege, or (iii)
exercise any and all other rights or remedies to which it may be entitled.
 
     THE METHOD OF DELIVERY OF SUBSCRIPTION CERTIFICATES AND PAYMENT OF THE
SUBSCRIPTION PRICE TO THE FUND WILL BE AT THE ELECTION AND RISK OF THE RIGHTS
HOLDERS, BUT IF SENT BY MAIL IT IS RECOMMENDED THAT SUCH CERTIFICATES AND
PAYMENT BE SENT BY REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT
REQUESTED, AND THAT A SUFFICIENT NUMBER OF DAYS BE ALLOWED TO ENSURE DELIVERY TO
THE FUND AND CLEARANCE OF PAYMENT PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE
EXPIRATION DATE. BECAUSE UNCERTIFIED PERSONAL CHECKS MAY TAKE AT LEAST FIVE
BUSINESS DAYS TO CLEAR AND, MAY AT THE DISCRETION OF THE FUND, NOT BE ACCEPTED
IF NOT CLEARED PRIOR TO THE

<PAGE>   19
 
EXPIRATION DATE, YOU ARE STRONGLY ENCOURAGED TO PAY, OR ARRANGE FOR PAYMENT, BY
MEANS OF CERTIFIED OR CASHIER'S CHECK OR MONEY ORDER.
 
     All questions concerning the timeliness, validity, form and eligibility of
any exercise of Rights will be determined by the Fund, whose determinations will
be final and binding. The Fund in its sole discretion may waive any defect or
irregularity, or permit a defect or irregularity to be corrected within such
time as it may determine, or reject the purported exercise of any Right.
Subscriptions will not be deemed to have been received or accepted until all
irregularities have been waived or cured within such time as the Fund determines
in its sole discretion. The Fund will not be under any duty to give notification
of any defect or irregularity in connection with the submission of Subscription
Certificates or incur any liability for failure to give such notification.
 
NOTICE OF NET ASSET VALUE DECLINE
 
   
     The Fund has, pursuant to the Commission's regulatory requirements,
undertaken to suspend the Offer until it amends this Prospectus if, subsequent
to April 14, 1998, the effective date of the Fund's Registration Statement, the
Fund's net asset value declines more than 10% from its net asset value as of
that date. Accordingly, the Expiration Date would be extended and the Fund would
notify Record Date Shareholders of any such decline and permit them to cancel
their exercise of the Rights.
    
 
NON-TRANSFERABILITY OF RIGHTS
 
     The Rights are non-transferable and, therefore, may not be purchased or
sold. The Rights will not be listed for trading on the NYSE, PCX or any other
exchange. However, the additional Shares of Common Stock to be issued upon the
exercise of the Rights and the Over-Subscription Privilege will be listed for
trading on the NYSE and PCX, subject to notice of issuance.
 
DELIVERY OF SHARE CERTIFICATES
 
     Stock certificates for all Shares acquired in the Primary Subscription will
be mailed promptly after the expiration of the Offer and full payment for the
subscribed Shares has been received and cleared. Certificates representing
Shares acquired pursuant to the Over-Subscription Privilege will be mailed as
soon as practicable after full payment has been received and cleared and all
allocations have been effected. Participants in the Fund's Distribution
Reinvestment and Cash Purchase Plan (the "Plan") will have any Shares acquired
in the Primary Subscription and pursuant to the Over-Subscription Privilege
credited to their shareholder distribution reinvestment accounts in the Plan.
Participants in the Plan wishing to exercise Rights for the shares of Common
Stock held in their accounts in the Plan must exercise them in accordance with
the procedures set forth above. Record Date Shareholders whose shares of Common
Stock are held of record by Cede or by any other depository or nominee on their
behalf or their broker-dealers' behalf will have any Shares acquired in the
Primary Subscription credited to the account of Cede or such other depository or
nominee. Shares acquired pursuant to the Over-Subscription Privilege will be
credited directly to Cede or such other depository or nominee.
 
FOREIGN RESTRICTIONS
 
     Record Date Shareholders whose record addresses are outside the United
States (for these purposes, the United States includes its territories and
possessions and the District of Columbia) will receive written notice of the
Offer; however, Subscription Certificates will not be mailed to such
shareholders. The Rights to which those Subscription Certificates relate will be
held by the Subscription Agent for such foreign Record Date Shareholders'
accounts until instructions are received in writing with payment to exercise the
Rights. If no such instructions are received by the Expiration Date, such Rights
will expire.
 
                                       15
<PAGE>   20
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The U.S. Federal income tax consequences to holders of Common Stock with
respect to the Offer will be as follows:
 
     For Federal income tax purposes, the distribution of Rights will not result
in taxable income to a shareholder nor will the shareholder recognize gain or
loss as a result of the exercise of the Rights. No loss will be recognized by a
shareholder if the Rights expire without exercise.
 
     The tax basis of a U.S. shareholder's Common Stock will remain unchanged
and the shareholder's basis in the Rights will be zero, unless such U.S.
shareholder affirmatively and irrevocably elects (in a statement attached to
such shareholder's U.S. Federal income tax return for the year in which the
Rights are received) to allocate the basis in the Common Stock between such
Common Stock and the Rights in proportion to their respective fair market values
on the date of distribution.
 
     If Rights are exercised by the holder of Common Stock, the basis of the
Common Stock received will equal the Subscription Price (plus any basis
allocated to the Rights in the manner described in the preceding paragraph). For
purposes of determining whether capital gain or loss recognized upon a
subsequent sale of the Common Stock acquired upon exercise of a Right (assuming
the Common Stock is held as a capital asset) is short-term, mid-term or
long-term, the holding period of the Common Stock so acquired will begin on the
date the Right is exercised.
 
     The foregoing is only a general summary of the applicable U.S. Federal
income tax law and does not include any state, local or foreign tax consequences
of the Offer. Such applicable U.S. Federal income tax law is subject to change
by legislative or administrative action. Shareholders should consult their tax
advisers concerning the tax consequences of the Offer. See "Taxation" in this
Prospectus and in the SAI.
 
EMPLOYEE PLAN CONSIDERATIONS
 
     Shareholders that are employee benefit plans subject to the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") (including
corporate savings and 401(k) plans), Keogh or H.R. 10 plans of self-employed
individuals and Individual Retirement Accounts ("IRAs") (collectively, "Plans")
should be aware of the complexity of the rules and regulations governing Plans
and the penalties for noncompliance, and Plans should consult with their counsel
regarding the consequences of their exercise of Rights under ERISA and the
Internal Revenue Code of 1986, as amended (the "Code").
 
                                USE OF PROCEEDS
 
   
     If all of the Rights are exercised in full and assuming a Subscription
Price of $8.85 per share (95% of the last reported sales price per share on the
NYSE on April 13, 1998), the net proceeds to the Fund would be approximately
$95,466,540, after deducting expenses payable by the Fund, including the fees
and expenses of the Dealer Manager and soliciting broker-dealers and other
offering expenses estimated to total $720,000. If the Fund increases the number
of Shares subject to subscription by up to 2,822,375 Shares, in order to satisfy
over-subscription requests, the additional net proceeds will be approximately
$24,046,635. However, there can be no assurance that all Rights will be
exercised in full, and the Subscription Price will not be determined until the
close of business on the Expiration Date. The Investment Adviser has advised the
Fund that it anticipates that the net proceeds of the Offer will be invested in
investments conforming to the Fund's investment objective and policies within a
week from their receipt by the Fund, but in no event will such investment take
longer than six months from the Expiration Date. Pending such investment, the
proceeds will be invested in cash or cash equivalent short-term obligations
including, but not limited to, U.S. Government obligations, certificates of
deposit, commercial paper and short-term notes. See "The Offer -- Purpose of the
Offer."

                                    THE FUND
 
     The Fund, incorporated in Maryland on July 21, 1988, is a diversified,
closed-end management investment company registered under the 1940 Act. The
Fund's investment objective is to seek the highest total return, consisting of
capital appreciation and current income, consistent with the preservation of
capital. The Fund will invest up to 65% of its total assets in U.S. Government
Securities, non-convertible debt securities of domestic issuers rated among the
two highest rating categories of either Moody's Investors Services, Inc. or
Standard & Poor's Corporation (or of comparable quality), and certain Foreign
Government Securities, and up to 35% of its total assets in equity securities.
The Fund may, however, under certain circumstances, invest up to 75% of its
total assets in equity securities. The extent of the Fund's investment in debt
and equity securities will be determined primarily on the basis of market timing
techniques developed by Dr. Martin E. Zweig, the President of the Fund's
Investment Adviser, and his staff. While the Investment Adviser seeks to reduce
the risks associated with investing in debt and equity securities by using these
techniques, the risk of investment in debt and equity securities cannot be
eliminated. See "Investment Objective and Policies." No assurance can be given
that the Fund's investment objective will be realized.
 
     The Fund's Investment Adviser, Zweig Total Return Advisors, Inc., is a
Delaware corporation. The President and majority shareholder of the Investment
Adviser is Dr. Zweig, who has been engaged in the business of providing
investment advisory services for over 25 years. The Investment Adviser is
registered with the Commission under the Investment Advisers Act of 1940, as
amended. Such registration does not involve supervision or approval by the
Commission of investment advice rendered by the Investment Adviser. See
"Management of the Fund."
 
   
     The Fund completed an initial public offering of 60,385,753 shares of its
Common Stock in September and October 1988. The net proceeds to the Fund from
such offering were approximately $559,912,503. As of April 13, 1998, the net
assets of the Fund were $691,600,000, and since inception, the Fund has paid
distributions (including dividends and capital gains distributions) aggregating
$591,344,008. The increase in the Fund's net assets since inception is
attributable primarily to appreciation in the value of its portfolio securities.
    
 
     The Fund's principal office is located at 900 Third Avenue, New York, New
York 10022, and its telephone number is (212) 451-1100.
 
                  MARKET PRICE AND NET ASSET VALUE INFORMATION

     The Fund's Shares of Common Stock have traded in the market above, at and
below net asset value since the commencement of the Fund's operations in
September 1988. During the past seven years, the Fund's shares have generally
traded in the market at a premium above net asset value; however, the Fund's
officers cannot predict whether the Subscription Price will be above, at or
below the Fund's net asset value per Share on the Pricing Date. Since the Fund's
inception in 1988, the Fund has maintained a policy of making monthly
distributions equal to 0.83% of its net asset value (10% on an annualized
basis). The Fund's officers believe that such policy may be partly responsible
for the Fund's shares generally trading in the market at a premium above net
asset value in recent years; however, the Fund's officers cannot predict whether
the Fund's shares in the future will generally trade in the market at a premium
above net asset value. See "Distributions; Distribution Reinvestment and Cash
Purchase Plan." The Fund is authorized to repurchase its shares on the open
market when the shares are trading at a discount from net asset value. The Fund
has not engaged in any such repurchases. See "Description of Common Stock
Repurchase of Shares." Since the Fund's inception, the Board of Directors has
maintained a policy pursuant to which the Board of Directors considers the
making of tender offers of the Fund each quarter during periods when the Fund's
shares are trading at a discount from net asset value. The Fund has not made any
such tender offers. See "Description of Common Stock -- Tender Offers." The
Fund's Articles of Incorporation provide that if during any fiscal quarter
beginning on or after January 1, 1990, the Fund's shares trade, on the principal
securities exchange on which they are traded, at an average discount from net
asset value of 10% or more, the Fund generally is required to submit to
shareholders within 60 days after the end of such quarter, a proposal to convert
the Fund to an open-end investment company (the "Conversion Proposal"). Approval
of the Conversion Proposal would require the affirmative vote of a majority of
the outstanding shares of the Fund entitled to be voted thereon. The Fund's
shares have not traded at an average discount from net asset value of 10% or
more during any quarter since the Fund's inception. Thus, the Fund has not
submitted any Conversion Proposals to its shareholders. See "Description of
Common Stock -- Provision for Conversion to Open-End Fund."
 
   
     On April 13, 1998, the net asset value per share of Common Stock was $8.75
and the last reported sales price was $9.3125, representing a premium from net
asset value per share of 6.43%.
    
 
                       INVESTMENT OBJECTIVE AND POLICIES
 
INVESTMENT OBJECTIVE
 
     The Fund's investment objective is to seek the highest total return,
consisting of capital appreciation and current income, consistent with the
preservation of capital. The Fund will invest up to 65% of its total assets in
U.S. Government Securities, non-convertible debt securities of domestic issuers
rated among the two highest rating categories of either Moody's Investors
Services, Inc. or Standard & Poor's Corporation (or of comparable quality), and
certain Foreign Government Securities, and up to 35% of its total assets in
equity securities. If the Investment Adviser believes that there is very low
risk in the stock market, then the Fund may invest up to 40% of its total assets
in equity securities. If, however, the Investment Adviser perceives a
fundamental change in the relationship between the debt and equity markets (such
as a significant change in the spread between the yields of debt and equity
securities from that experienced during the past decade), then, depending on the
nature of such change, the Fund may substantially increase the percentage of its
total assets invested in debt securities (including money market instruments) or
equity securities. The Fund will not, under any circumstances, invest more than
75% of its total assets in equity securities.
 
     The extent of the Fund's investment in debt and equity securities will be
determined primarily on the basis of market timing techniques developed by Dr.
Martin E. Zweig, the President of the Fund's Investment Adviser, and his staff.
In an effort to meet the Fund's investment objective, the Fund may use the
following investment methods when such use is deemed appropriate: purchasing and
selling interest rate, stock index and other futures contracts and purchasing
options on such futures; purchasing and writing listed put and call security
options and options on stock indexes; short sales of securities; borrowing from
banks to purchase securities; investing in securities of closed-end investment
companies and foreign issuers; lending portfolio securities to brokers, dealers,
banks or other recognized institutional borrowers of securities; entering into
repurchase or reverse repurchase agreements; and purchasing when-issued and
delayed-delivery securities.
                                       18
<PAGE>   23
 
See "Special Investment Methods." During periods when the Investment Adviser
believes an overall defensive position is advisable, greater than 50% (and under
certain circumstances perhaps all) of the Fund's total assets may be temporarily
invested in money market instruments and cash. There is no assurance that the
Fund will achieve its investment objective. The Fund's investment objective may
not be changed without the approval of a majority of the Fund's outstanding
securities. As used in this Prospectus, the term "majority of the Fund's
outstanding voting securities" means the lesser of either (i) 67% of the shares
represented at a shareholders meeting at which the holders of more than 50% of
the outstanding shares are present in person or by proxy, or (ii) more than 50%
of the outstanding shares.
 
INVESTMENT POLICIES
 
     In determining the extent of the Fund's investment in debt and equity
securities, the Investment Adviser will rely primarily on market timing
techniques developed by Dr. Zweig and his staff. It is expected that the
Investment Adviser will make most of the decisions with respect to the extent of
the Fund's investment in debt and equity securities based on these techniques.
The debt market timing techniques, which seek to identify the risks and trends
in the debt markets at any given time, will incorporate various indicators,
including the momentum of bond prices, short-term interest rate trends,
inflation indicators and general economic and liquidity indicators, as well as
other market indicators and statistics which the Investment Adviser believes
tend to point to significant trends in the overall performance and the risk of
the debt markets. The equity market timing techniques, which seek to identify
the risks and trends in the equity markets at any given time, include general
market indicators, including interest rate and monetary analysis, market
sentiment indicators, price and trading volume statistics, and measures of
valuation, as well as other market indicators and statistics which the
Investment Adviser believes tend to point to significant trends in the overall
performance and the risk of the stock market. These techniques are not an all-in
or all-out approach that attempts to predict market tops and bottoms. Instead,
they are intended to be a gradual and disciplined approach that reacts to
changes in risk levels as determined by the indicators. The goal is to be
invested consistent with the major trends of the markets. There is no assurance
that these market timing techniques will provide protection from the risks of
debt or equity investment, enable the Fund to be invested consistent with the
major trends of the markets or enable the Fund to achieve its investment
objective.
 
     The maturities of the debt securities in the Fund's portfolio will vary
based in large part on the Investment Adviser's expectations of future changes
in interest rates using the Investment Adviser's own internal research and debt
market timing techniques. The primary consideration in choosing among bonds is
managing risk related to changes in interest rate levels. A bond's duration
measures its sensitivity to changes in interest rates (interest rate risk).
Duration is the approximate percentage change in the price of a bond or bond
portfolio in response to a 100 basis point (one percent) change in the general
level of interest rates in the market. For example, if a bond portfolio has an
average duration of five years, the value of such bond portfolio would increase
by 5% if interest rates declined by 1% and conversely would decrease by 5% if
interest rates rose by 1%. The longer the duration, the greater the bond's price
movement will be as interest rates change. The Investment Adviser manages the
duration of the Fund's portfolio, or interest rate risk, by altering the Fund's
mix of short, medium, and long term bonds, or by buying or selling interest rate
futures contracts, and also by actively using money market and cash instruments.
Over time, the duration will vary depending on the Investment Adviser's interest
rate outlook.
 
     The U.S. government securities ("U.S. Government Securities") in which the
Fund may invest are securities issued or guaranteed by the U.S. Government or
its agencies or instrumentalities (including repurchase agreements secured by
such instruments). Certain of these securities, including U.S. Treasury bills,
notes and bonds, mortgage participation certificates guaranteed by GNMA, and
Federal Housing Administration debentures, are supported by the full faith and
credit of the United States. Other U.S. Government Securities issued or
guaranteed by federal agencies or government-sponsored enterprises are not
supported by the full faith and credit of the United States. These securities
include obligations supported by the right of the issuer to borrow from the U.S.
Treasury, such as obligations of Federal Home Loan Banks, and obligations
supported only by the credit of the instrumentality, such as Federal National
Mortgage Association bonds. Debt securities of domestic issuers, other than U.S.
Government Securities, will be limited
 
                                       19
<PAGE>   24
 
to those that are rated, as of the date of purchase, among the two highest
rating categories (Aaa and Aa) of Moody's Investors Service, Inc. ("Moody's") or
the two highest rating categories (AAA and AA) of Standard & Poor's Corporation
("S&P").
 
     The money market instruments in which the Fund may invest include U.S.
Government Securities or obligations issued or guaranteed by one or more foreign
governments or any of their political subdivisions, agencies or
instrumentalities ("Foreign Government Securities") having a maturity of less
than one year, commercial paper rated A-1 or higher by S&P or Prime-1 or higher
by Moody's, or if such commercial paper is not rated, issued by companies which
have an outstanding debt issue rated Aa or higher by Moody's or AA or higher by
S&P, repurchase agreements secured by collateral at least equal to the
repurchase price, and certificates of deposit, bankers' acceptances and other
short-term obligations issued by domestic branches of U.S. banks that are
insured by the Federal Deposit Insurance Corporation and have assets in excess
of $500 million.
 
     The Fund may invest up to 10% of its total assets in Foreign Government
Securities that, in the opinion of the Investment Adviser, do not subject the
Fund to unreasonable credit risks. The percentage of the Fund's assets invested
in Foreign Government Securities will vary depending on the relative yields of
such securities, the economic and financial markets of the countries in which
the investments are made, the interest rate climate of such countries and the
relationship of such countries' currencies to the U.S. dollar. During the past
year, the Fund has not owned any Foreign Government Securities.
 
     The Fund's investments in equity securities provide the opportunity for
enhanced returns through capital appreciation. The Investment Adviser expects
that the stocks in the Fund's portfolio will be widely diversified by both
industry and the number of issuers. The Investment Adviser expects that a
majority of the stocks in the Fund's portfolio will be selected on the basis of
a proprietary stock selection model that evaluates and ranks higher dividend
yield stocks. The Investment Adviser will consider, from a list of approximately
1,500 of the most liquid stocks, approximately 750 stocks with the highest
dividend yields. The Investment Adviser will then use, for the selection of
stocks, a proprietary stock selection model that evaluates and ranks such higher
dividend yield stocks on the basis of various factors, which may include
earnings momentum, earnings growth, price-to-book value, price-to-earnings,
price-to-cash flow, cash flow trend, payout ratio trend and other market
measurements. This stock selection model may evolve or be replaced by other
stock selection models intended to achieve the Fund's investment objective.
 
SPECIAL INVESTMENT METHODS
 
     The Fund may make frequent use of some or all of the following special
investment methods where their use appears appropriate to the Investment
Adviser. The investment methods described below are subject to, and should be
read in conjunction with, the discussion under "Investment Restrictions" and
"Investment Objective and Policies" in the SAI. The restrictions set forth under
"Investment Restrictions" are fundamental, and thus may be changed only with the
approval of a majority of the Fund's outstanding voting securities.
 
     Futures Contracts and Related Options.  The Fund may purchase and sell
interest rate futures contracts, stock index futures contracts and futures
contracts based upon other financial instruments, and purchase options on such
contracts. The Fund will not write options on any futures contracts. Such
investments will generally be made by the Fund only for the purpose of hedging
against the effect that changes in general market conditions and conditions
affecting particular industries may have on the values of securities held in the
Fund's portfolio, or which the Fund intends to purchase.
 
     In general, the Fund will establish short positions in (sell) futures
contracts to hedge against anticipated or potential declines in the market value
of the Fund's portfolio of securities. For example, when the Fund anticipates a
general market or market sector decline that may adversely affect the market
value of the Fund's portfolio securities, it may establish short positions in
interest rate or stock index futures contracts.
 
     Where the Fund anticipates a significant market or market sector advance,
establishing long positions in (purchasing) interest rate or stock index futures
contracts ("long hedge") affords a hedge against not participating in such
advance at a time when the Fund is not fully invested. For example, if the Fund
 
                                       20
<PAGE>   25
 
anticipates a significant stock market or market sector advance, such long
hedges would serve as a temporary substitute for the purchase of individual
stocks, which may then be purchased in an orderly fashion. As purchases of stock
are made, an amount of stock index futures contracts which is comparable to the
amount of stock purchased may be terminated by offsetting closing sales
transactions.
 
     There are certain risks associated with the use of futures contracts and
related options. The low margin normally required in such trading provides a
large amount of leverage. Thus, a relatively small change in the price of a
contract can produce a disproportionately large profit or loss, and the Fund may
gain or lose substantially more than the initial margin on a trade. Although the
Fund intends to purchase or sell futures which appear to have an active market,
there is no assurance that a liquid market will exist for any particular
contract at any particular time. Thus, it may not be possible to close a futures
position in anticipation of adverse price movements. In addition, there may be
an imperfect correlation between the price movements of the futures contracts
and price movements of the portfolio securities being hedged.
 
     Security and Stock Index Options.  The Fund may purchase and write listed
put and call options on securities and on stock indexes that are traded on U.S.
securities exchanges at such times as the Investment Adviser deems appropriate
and consistent with the Fund's investment objective. In general, the Fund will
purchase or write such options to hedge against anticipated or potential
declines in the market value of the Fund's portfolio of securities, or to
facilitate the rapid implementation of investment strategies if the Fund
anticipates a significant market or market sector advance.
 
     Borrowing.  Although the Fund has not done so in the past and does not
expect to do so during the next year, the Fund may from time to time increase
its ownership of securities above the amounts otherwise possible by borrowings
from banks on an unsecured basis and investing the borrowed funds. In addition,
the Fund may borrow to finance share repurchase or tender offer transactions
when the shares are trading at a discount from net asset value. See "Description
of Common Stock -- Repurchase of Shares," and "-- Tender Offers." Any such
borrowing will be made only from banks, and pursuant to the requirements of the
1940 Act, will only be made to the extent that the value of the Fund's total
assets, less its liabilities other than borrowings, is equal to at least 300% of
all borrowings including the proposed borrowing.
 
     Borrowing for investment and to finance share repurchase or tender offer
transactions increases both investment opportunity and investment risk. Since
substantially all of the Fund's assets will fluctuate in value, but the
obligation resulting from the borrowing is relatively fixed, the Fund's shares
will increase in value more when the Fund's assets increase in value and
decrease more when the Fund's assets decrease in value than would otherwise be
the case. In addition, the cost of borrowing may exceed the income or gain on
any securities purchased with the funds borrowed, in which case the Fund's net
asset value will decline.
 
     Closed-end Investment Companies.  The Fund may also invest in closed-end
investment companies if the Investment Adviser believes that such investments
will further the Fund's investment objective. If the Fund purchases shares of
another investment company at a discount which subsequently declines, the
performance of such investment generally would be better than if the Fund had
purchased the underlying portfolio investments of such other investment company.
Such investments in other investment companies will constitute less than 10% of
the Fund's net assets.
 
     Foreign Securities.  The Fund may invest up to 10% of its total assets in
Foreign Government Securities and up to 10% of its total assets in equity
securities of foreign issuers. Investments in foreign securities offer potential
benefits not available through investment solely in securities of domestic
issuers. Foreign securities offer the opportunity to invest in foreign issuers
that appear to have growth potential, or in foreign countries with economic
policies or business cycles different from those of the United States, or to
reduce fluctuations in portfolio value by taking advantage of foreign markets
that do not move in a manner parallel to United States markets. The Fund may
also enter into foreign currency transactions in connection with its investment
activity in foreign securities.
 
     Investments in foreign securities present special additional risks and
considerations not typically associated with investments in domestic securities.
Foreign investments may be affected by changes in foreign currency rates and
exchange control regulations. There may be less information available about a
foreign
 
                                       21
<PAGE>   26
 
company than a domestic company, and foreign companies may not be subject to
accounting, auditing and reporting standards and requirements comparable to
those applicable to domestic companies. Foreign securities may be less liquid
and subject to greater price volatility than domestic securities. The foreign
markets also have different clearance and settlement procedures. Foreign
investments may also be subject to local economic or political risks, political
instability and possible nationalization of issuers or expropriation of their
assets which might adversely affect the Fund's ability to realize or liquidate
its investment in such securities. Furthermore, legal remedies for defaults and
disputes may have to be pursued in foreign courts whose procedures differ
substantially from those of U.S. courts. In the event of a default in payment on
foreign securities, the Fund may incur increased costs to obtain and/or to
enforce a judgment against the foreign issuer (or the other parties to the
transaction) in the United States or abroad, and no assurance can be given that
the Fund will be able to collect on any such judgment.
 
     Short Sales.  The Fund may from time to time make short sales of
securities. A short sale is a transaction in which the Fund sells a security it
does not own in anticipation of a decline in market price. The Fund may make
short sales to offset a potential decline in a long position or a group of long
positions, or if the Investment Adviser believes that a decline in the price of
a particular security or group of securities is likely. The Fund may also make
short sales in an attempt to maintain portfolio flexibility and facilitate the
rapid implementation of investment strategies if the Investment Adviser believes
that the price of a particular security or group of securities is likely to
decline.
 
     When the Fund determines to make a short sale of a security, it must borrow
the security. The Fund's obligation to replace the security borrowed in
connection with the short sale will be fully secured by the proceeds from the
short sale retained by the broker and by cash or liquid securities deposited in
a segregated account with the Fund's custodian.
 
     The Fund may make a short sale only if, at the time the short sale is made
and after giving effect thereto, the market value of all securities sold short
is 25% or less of the value of its net assets and the market value of securities
sold short which are not listed on a national securities exchange does not
exceed 10% of the Fund's net assets.
 
     In addition to the short sales described above, the Fund may make short
sales "against the box." A short sale "against the box" is a short sale where,
at the time of the short sale, the Fund owns or has the immediate and
unconditional right, at no added cost, to obtain the identical security. The
Fund would enter into such a transaction to defer a gain or loss for Federal
income tax purposes on the security owned by the Fund. Short sales against the
box are not subject to the collateral requirements described above or the
percentage limitations on short sales described above.
 
     Lending Portfolio Securities.  Although the Fund has not done so in the
past, the Fund may lend portfolio securities, generally on a short-term basis,
to brokers or dealers in corporate or governmental securities, banks or other
institutional borrowers of securities, and financial institutions as a means of
earning income. A borrower of securities from the Fund must maintain with the
Fund cash or U.S. Government Securities equal to at least 100% of the market
value of the securities borrowed. The Fund may not lend portfolio securities if
such loan would cause the aggregate amount of all outstanding securities loans
to exceed 20% of the current market value of the Fund's net assets. If a
borrower becomes bankrupt or defaults on its obligation to return the loaned
security, delays or losses could result.
 
     Repurchase Agreements.  Although the Fund has not done so in the past, the
Fund may from time to time acquire U.S. Government Securities and concurrently
enter into so-called "repurchase agreements" with the seller, a member bank of
the Federal Reserve System or primary dealers in U.S. Government Securities,
whereby the seller agrees to repurchase such securities at the Fund's cost plus
interest within a specified time (usually on the next business day). Repurchase
agreements offer a means of generating income from excess cash that the Fund
might otherwise hold. Delays in payment or losses may result if the other party
to the agreement defaults or becomes bankrupt. The Fund's repurchase agreements
must be fully backed by collateral that is marked to market, or priced, each
day.
 
                                       22
<PAGE>   27
 
     Reverse Repurchase Agreements.  Although the Fund has not done so in the
past, the Fund may enter from time to time into reverse repurchase agreements
whereby the Fund sells an underlying debt instrument and simultaneously obtains
the commitment of the purchaser, a commercial bank or a broker or dealer, to
sell the security back to the Fund at an agreed upon price on an agreed upon
date. The value of the underlying securities will be required to be maintained
at a level at least equal at all times to the total amount of the resale
obligation, including the interest factor. The Fund receives payment for such
securities only upon physical delivery or evidence of book entry transfer by its
custodian. The Fund will establish a segregated account with the Fund's
custodian, in which the Fund will maintain cash and U.S. Government Securities
or other high grade debt obligations at least equal in value to the total amount
of the repurchase obligation, including accrued interest. The value of the
segregated securities will be marked-to-market on a daily basis to ensure that
such value is maintained. Reverse repurchase agreements could involve certain
risks in the event of default or insolvency of the other party, including
possible delays or restrictions upon the Fund's ability to dispose of the
underlying securities. An additional risk is that the market value of securities
sold by the Fund under a reverse repurchase agreement could decline below the
price at which the Fund is obligated to repurchase them. Reverse repurchase
agreements will be considered borrowings by the Fund and as such will be subject
to the restrictions on borrowing described in the SAI under "Investment
Restrictions." The value of all the Fund's reverse repurchase agreements will
not exceed 5% of the Fund's total assets.
 
     When-Issued and Delayed-Delivery Securities.  The Fund may from time to
time purchase securities on a "when-issued" or "delayed-delivery" basis whereby
the Fund purchases a bond or stock with delivery of the security and payment
deferred to a future date. The money to purchase such securities will be
invested in other securities until the Fund receives delivery. This could
increase the possibility that the Fund's net asset value would increase or
decrease faster than would otherwise be the case. There is no restriction on the
percentage of the Fund's assets that may be invested in when-issued or
delayed-delivery securities, and such securities are not considered to be short
sales for purposes of the Fund's Investment Restrictions on short sales.
Securities purchased on a when-issued or delayed-delivery basis may expose the
Fund to risk, since such securities may experience fluctuations in value (based
upon, in the case of bonds, the public's perception of the creditworthiness of
the issuer and changes, real or anticipated, in the level of interest rates)
prior to their time of delivery. In addition, the yield available in the market
when the delivery takes place actually may be higher than that obtained in the
transaction itself.
 
                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
     The following discusses certain matters that should be considered, among
others, in connection with the Offer.
 
DILUTION -- NET ASSET VALUE AND NON-PARTICIPATION IN THE OFFER
 
   
     Record Date Shareholders who do not fully exercise their Rights will, upon
the completion of the Offer, own a smaller proportional interest in the Fund
than they owned prior to the Offer. In addition, an immediate dilution of the
net asset value per share may be experienced by all shareholders as a result of
the Offer because the Subscription Price may be less than the then current net
asset value per share, and the number of shares outstanding after the Offer may
increase in greater percentage than the increase in the size of the Fund's
assets. Although it is not possible to state precisely the amount of such
decrease in net asset value per share, if any, because it is not known at this
time what the Subscription Price will be, what the net asset value per share
will be on the Expiration Date, or what proportion of the Shares will be
subscribed for, such dilution could be minimal or substantial. For example,
assuming (i) all Rights are exercised, (ii) the Fund's net asset value on the
Expiration Date is $8.75 per share (the net asset value per share on April 13,
1998), and (iii) the Subscription Price is $8.85 per share (95% of the last
reported sale price per share on the NYSE on April 13, 1998), then the Fund's
net asset value per share would be reduced by approximately $0.04 per share or
0.46%.

LEVERAGE AND BORROWING
 
     As discussed above under "Special Investment Methods", the Fund is
authorized to borrow. The Fund has not borrowed money in the past, and does not
have any intention at this time to borrow money in the future. Borrowings create
an opportunity for greater capital appreciation with respect to the Fund's
investment portfolio, but at the same time such borrowing is speculative in that
it will increase the Fund's exposure to capital risk. In addition, borrowed
funds are subject to interest costs that may offset or exceed the return earned
on the borrowed funds.
 
CERTAIN INVESTMENT STRATEGIES
 
     The extent of the Fund's investment in debt and equity securities will be
determined primarily on the basis of market timing techniques developed by Dr.
Zweig and his staff. While the Investment Adviser seeks to reduce the risks
associated with investing in debt and equity securities by using these
techniques, the risk of investment in equity securities cannot be eliminated.
There is no assurance that these market timing techniques will provide
protection from the risks of debt and equity investment, enable the Fund to be
invested consistent with the major trends of the markets or enable the Fund to
achieve its investment objective.
 
     In addition, although the Investment Adviser believes that the special
investment methods discussed above under "Special Investment Methods" (including
purchasing and selling interest rate, stock index and other futures contracts
and purchasing options on such futures; purchasing and writing listed put and
call security options and options on stock indexes; short sales of securities;
borrowing from banks to purchase securities; investing in securities of
closed-end investment companies and foreign issuers; lending portfolio
securities to brokers, dealers, banks or other recognized institutional
borrowers of securities; entering into repurchase or reverse repurchase
agreements; and purchasing when-issued and delayed-delivery securities) will
further the Fund's investment objective and reduce losses that might otherwise
occur during a time of general decline in debt or equity security prices, no
assurance can be given that these investment methods will achieve this result.
These methods may subject an investor in the Fund to greater than average risks
and costs.
 
UNREALIZED APPRECIATION
 
     As of December 31, 1997, there was $50,238,438 or approximately $0.64 per
share of net unrealized appreciation in the Fund's net assets of $677,133,054,
if realized and distributed, or deemed distributed, such gains would, in
general, be taxable to shareholders, including holders at that time of Shares
acquired upon the exercise of Rights. See "Taxation."
 
DISCOUNT FROM NET ASSET VALUE
 
     The Fund's Shares of Common Stock have traded in the market above, at and
below net asset value since the commencement of the Fund's operations in
September 1988. During the past seven years, the Fund's shares have generally
traded in the market at a premium above net asset value; however, the Fund
cannot predict whether the Fund's Common Stock will in the future trade at a
premium to or discount from net asset value. The risk of the Common Stock
trading at a discount is a risk separate from a decline in the Fund's net asset
value. See "Market Price and Net Asset Value Information" in this Prospectus and
"Net Asset Value" in the SAI.
 
DISTRIBUTIONS
 
     The Fund's policy is to make monthly distributions equal to 0.83% of its
net asset value (10% on an annualized basis). If, for any monthly distribution,
net investment income and net realized short-term capital gains are less than
the amount of the distribution, the difference will be distributed from the
Fund's assets. The Fund's final distribution for each calendar year will include
any remaining net investment income and net realized short-term capital gains
deemed, for Federal income tax purposes, undistributed during the year, as well
as all net long-term capital gains realized during the year. If, for any
calendar year, the total distributions exceed net investment income and net
realized capital gains, the excess, distributed from the Fund's assets, will
generally be treated as a tax-free return of capital (up to the amount of the
shareholder's tax basis in his or
                                       24
<PAGE>   29
 
her shares). The amount treated as a tax-free return of capital will reduce a
shareholder's adjusted basis in his or her shares, thereby increasing his or her
potential gain or reducing his or her potential loss on the sale of his or her
shares. Such excess, however, will be treated as ordinary dividend income, and
will not reduce a shareholder's adjusted basis in his or her shares, up to the
amount of the Fund's current and accumulated earnings and profits. Pursuant to
the requirements of the 1940 Act and other applicable laws, a notice will
accompany each monthly distribution with respect to the estimated source of the
distribution made. Such distribution policy may, under certain circumstances,
have certain adverse consequences to the Fund and its shareholders. In the event
the Fund distributes amounts in excess of its net investment income and net
realized capital gains, such distributions will decrease the Fund's total assets
and, therefore, have the likely effect of increasing the Fund's expense ratio.
In addition, in order to make such distributions, the Fund may have to sell a
portion of its investment portfolio at a time when independent investment
judgment might not dictate such action. Shares purchased pursuant to the Offer
will be issued after the record date for the monthly distribution declared in
May, and, accordingly, the Fund will not pay a monthly distribution with respect
to such Shares until the distribution to be declared and paid in June. See
"Distributions; Distribution Reinvestment and Cash Purchase Plan" for a
discussion of the Fund's distribution policy.
 
ANTI-TAKEOVER PROVISIONS
 
     The Fund has provisions in its Articles of Incorporation and By-Laws that
may have the effect of limiting the ability of other entities or persons to
acquire control of the Fund, to cause it to engage in certain transactions or to
modify its structure. The Board of Directors is divided into three classes. At
the annual meeting of shareholders each year, the term of one class will expire
and directors will be elected to serve in that class for terms of three years.
This provision could delay for up to two years the replacement of a majority of
the Board of Directors.
 
     These provisions could have the effect of limiting shareholders'
opportunity to sell their shares at a premium over prevailing market prices by
discouraging a third party from seeking to obtain control of the Fund in a
tender offer or similar transaction. See "Description of Common Stock -- Special
Voting Provisions."
 
YEAR 2000 PREPAREDNESS
 
     Because computers were designed only using two fields to indicate the year,
at midnight December 31, 1999, computers will be unable to recognize that
January 1 is the year 2000. The major systems that would impact the Fund with
respect to the year 2000 are those of the transfer agent and custodian. The Fund
has been advised in writing by both the transfer agent and custodian that they
are working to fix, and expect to have fixed in time, all of the issues relating
to the year 2000. While management of the Fund will continue to monitor the
progress of the transfer agent and custodian in solving the year 2000 problem,
no assurance can be given that their systems will be fixed on time, or what the
magnitude of the problems would be if such systems are not fixed.
 
                             MANAGEMENT OF THE FUND
 
BOARD OF DIRECTORS
 
     The management of the Fund, including general supervision of the duties
performed by the Investment Adviser under the Investment Advisory Agreement (as
described below), is the responsibility of the Fund's Board of Directors. For
certain information regarding the Directors and officers of the Fund, see
"Management -- Directors and Officers" in the SAI.
 
INVESTMENT ADVISER
 
     The Fund's Investment Adviser, Zweig Total Return Advisors, Inc., is a
Delaware corporation, with offices at 900 Third Avenue, New York, New York
10022. The Investment Adviser was organized in June
 
                                       25
<PAGE>   30
 
1988 for the purpose of acting as investment adviser to the Fund. Dr. Zweig owns
a majority of the outstanding shares of the Investment Adviser.
 
     Pursuant to an investment advisory agreement between the Investment Adviser
and the Fund, dated September 22, 1988 ("the Investment Advisory Agreement"),
the Investment Adviser is responsible for the actual management of the Fund's
portfolio. The responsibility for making decisions to buy, sell or hold a
particular investment rests with the Investment Adviser, subject to review by
the Board of Directors and the applicable provisions of the 1940 Act. The
Investment Adviser is not dependent on any other party in providing the
investment advisory services required for the management of the Fund. The
Investment Adviser may, however, consider analyses from various sources,
including broker-dealers with which the Fund does business and affiliates of the
Investment Adviser. The Investment Adviser is also obligated to provide the Fund
with such executive, data processing, clerical, accounting and bookkeeping
services and statistical and research data as are deemed advisable by the Fund's
Board of Directors, except to the extent these services are provided by an
administrator hired by the Fund.
 
     For the services provided by the Investment Adviser under the Investment
Advisory Agreement, the Fund will pay the Investment Adviser a monthly fee
computed at the annual rate of 0.70% of the Fund's average daily net assets
during the previous month. For the fiscal years ended December 31, 1997, 1996
and 1995, the Fund accrued investment advisory fees of $4,571,606, $4,415,349,
and $4,330,481.
 
     Zweig Securities Corp. or any other brokerage affiliate (the "Brokerage
Affiliate") may act as a broker for the Fund. In order for the Brokerage
Affiliate to effect any portfolio transactions for the Fund, the commissions,
fees or other remuneration received by the Brokerage Affiliate must be
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers in connection with comparable transactions involving similar
securities being purchased or sold on an exchange during a comparable period of
time. The Fund will not deal with a Brokerage Affiliate in any portfolio
transaction in which the Brokerage Affiliate would act as principal.
 
DR. MARTIN E. ZWEIG
 
     Dr. Zweig, the President of the Fund and the Investment Adviser, has been
in the business of providing investment advisory services for over 25 years and
is the President and/or Chairman of investment advisory firms which, as of
December 31, 1997, managed in excess of $7 billion in assets. Dr. Zweig and his
associates determine the asset allocation strategy for the Fund. Dr. Zweig does
not select the individual securities to implement the strategy. The portfolio
managers select the specific securities for the Fund.
 
PORTFOLIO MANAGERS
 
     The day-to-day bond selections for the Fund are made by Mr. Carlton Neel,
and the day-to-day stock selections for the Fund are made by Mr. Jeffrey Lazar.
Mr. Neel has been making the day-to-day bond selections for the Fund and The
Zweig Fund, Inc. since July 1995. He is also the portfolio manager for the
following series of Zweig Series Trust: Zweig Managed Assets, Zweig Government
Fund and Zweig Foreign Equity Fund. Prior to joining the Investment Adviser in
1995, Mr. Neel was a Vice President with J.P. Morgan & Co., Inc. Mr. Lazar has
been Vice President of the Fund since 1988, and is also a Director of the Fund.
He has been making the day-to-day stock selections for the Fund and The Zweig
Fund, Inc. since January 1995. Mr. Lazar, who is a Vice President of the
Investment Adviser, has been with the Investment Adviser since 1988.
 
INVESTMENT ADVISORY AGREEMENT
 
     The Investment Advisory Agreement sets forth the services to be provided by
and the fees to be paid to each party, as described above. The Investment
Advisory Agreement provides that the Investment Adviser's liability to the Fund
and its shareholders is limited to situations involving its own willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its reckless disregard of its duties and obligations under the
Investment Advisory Agreement.
 
                                       26
<PAGE>   31
 
     The services of the Investment Adviser to the Fund are not deemed to be
exclusive, and the Investment Adviser or any affiliate thereof may provide
similar services to other investment companies and other clients or engage in
other activities.
 
     The Investment Advisory Agreement obligates the Investment Adviser to
provide advisory services and to pay all expenses arising from the performance
of its obligations under the Investment Advisory Agreement, as well as the fees
of all Directors of the Fund who are employees of the Investment Adviser or any
of its affiliates. The Fund pays all other expenses incurred in the operation of
the Fund including, but not limited to, direct charges relating to the purchase
and sale of portfolio securities, interest charges, fees and expenses of
attorneys and auditors, taxes and governmental fees, cost of stock certificates
and any other expenses (including clerical expenses) of issuance, sale or
repurchase of the Fund's common stock, expenses in connection with the Fund's
Distribution Reinvestment and Cash Purchase Plan, membership fees in trade
associations, expenses of registering and qualifying shares of the Fund's common
stock for sale under Federal and state securities laws, expenses of obtaining
and maintaining any stock exchange listings of the Fund's common stock, expenses
of printing and distributing reports, prospectuses, notices and proxy materials,
expenses of corporate data processing and related services, shareholder record
keeping and shareholder account services (including salaries of shareholder
relations personnel), expenses of auditors and escrow agents, expenses of
printing and filing reports and other documents filed with governmental
agencies, expenses of annual and special shareholders' meetings, fees and
disbursements of the Fund's administrator, transfer agent, custodian and
subcustodians (if any), expenses of disbursing dividends and distributions,
fees, expenses and out-of-pocket costs of Directors of the Fund who are not
interested persons of the Fund or the Investment Adviser, insurance premiums and
litigation, indemnification and other expenses not expressly provided for in the
Investment Advisory Agreement or the Administration Agreement.
 
     The Investment Advisory Agreement will remain in effect from year to year
if approved annually (i) by the Board of Directors of the Fund or by the holders
of a majority of the Fund's outstanding voting securities, and (ii) by a
majority of the Directors who are not parties to the Investment Advisory
Agreement or interested persons of any such party. The Investment Advisory
Agreement terminates on its assignment by either party, and may be terminated
without penalty on not more than 60 days' prior written notice at the option of
either party thereto, or by the affirmative vote of the holders of a majority of
the Fund's outstanding voting securities.
 
     The Investment Advisory Agreement provides that the Fund may use "Zweig" as
part of its name for so long as the Investment Adviser serves as investment
adviser to the Fund. The Fund has agreed that, in the event the Investment
Advisory Agreement is terminated, the Fund will promptly take such actions as
may be necessary to change its corporate name to one not containing the word
"Zweig", and the Fund will thereafter not transact business in a corporate name
using the word "Zweig" in any form or combination whatsoever. The Fund has also
acknowledged that the word "Zweig" is a property right of Dr. Martin E. Zweig
and that Dr. Martin E. Zweig or, pursuant to his consent, the Investment Adviser
may at any time permit others to use the word "Zweig."
 
ADMINISTRATOR
 
     Zweig/Glaser Advisers (the "Administrator") serves as the Fund's
administrator pursuant to an administration agreement dated August 1, 1995 (the
"Administration Agreement"). Martin E. Zweig (the President and Chairman of the
Board of the Fund) and Eugene J. Glaser (a Director of The Zweig Fund, Inc.) are
the Chairman and President, respectively, and the principal owners of the
Administrator. The Administrator generally assists in all aspects of the Fund's
operations, other than providing investment advice, subject to the overall
authority of the Fund's Board of Directors. The Administrator determines the
Fund's net asset value daily, prepares such figures for publication on a weekly
basis, maintains certain of the Fund's books and records that are not maintained
by the Investment Adviser, custodian or transfer agent, assists in the
preparation of financial information for the Fund's income tax returns, proxy
statement, quarterly and annual shareholder reports, and responds to shareholder
inquiries.
 
     The Fund pays the Administrator a monthly fee computed at an annual rate of
0.13% of the Fund's average daily net assets during the previous month. For the
fiscal years ended December 31, 1997 and 1996
 
                                       27
<PAGE>   32
 
and the period August 1, 1995 to December 31, 1995, the Fund accrued
administrative fees of $849,013, $819,993, and $345,212. During the period May
6, 1994 to July 31, 1995, The Shareholder Services Group, Inc. ("TSSG") served
as the Fund's Administrator and received fees equal, on an annual basis, to
0.18% of the Fund's average daily net assets during the previous month. During
the period January 1, 1995 to July 31, 1995, the Fund paid TSSG administrative
fees of $635,566.
 
        DISTRIBUTIONS; DISTRIBUTION REINVESTMENT AND CASH PURCHASE PLAN
 
     The Fund's policy is to distribute to shareholders on a monthly basis 0.83%
of its net asset value (10% on an annualized basis). If, for any monthly
distribution, net investment income and net realized short-term capital gains
are less than the amount of the distribution, the difference will be distributed
from the Fund's assets. The Fund's final distribution for each calendar year
will include any remaining net investment income and net realized short-term
capital gains deemed, for Federal income tax purposes, undistributed during the
year, as well as all net long-term capital gains realized during the year. If,
for any calendar year, the total distributions exceed net investment income and
net realized capital gains, the excess, distributed from the Fund's assets, will
generally be treated as a tax-free return of capital (up to the amount of the
shareholder's tax basis in his or her shares). The amount treated as a tax-free
return of capital will reduce a shareholder's adjusted basis in his or her
shares, thereby increasing his or her potential gain or reducing his or her
potential loss on the sale of his or her shares. Such excess, however, will be
treated as ordinary dividend income up to the amount of the Fund's current and
accumulated earnings and profits. In calculating the amount of each monthly
distribution, the Fund's net asset value will be measured as of the business day
immediately preceding the declaration date of such distribution. Pursuant to the
requirements of the 1940 Act and other applicable laws, a notice will accompany
each monthly distribution with respect to the estimated source of the
distribution made.
 
     In the event the Fund distributes amounts in excess of its net investment
income and net realized capital gains, such distributions will decrease the
Fund's total assets and, therefore, have the likely effect of increasing the
Fund's expense ratio. In addition, in order to make such distributions, the Fund
may have to sell a portion of its investment portfolio at a time when
independent investment judgment might not dictate such action.
 
     Shares purchased pursuant to the Offer will be issued after the record date
for the monthly distribution declared in May, and, accordingly, the Fund will
not pay a monthly distribution with respect to such Shares until the
distribution to be declared and paid in June.
 
     Shareholders may elect to receive all distributions in cash paid by check
mailed directly to the shareholder by State Street Bank & Trust Co. ("State
Street"), as dividend paying agent. Pursuant to the Distribution Reinvestment
and Cash Purchase Plan (the "Plan"), shareholders not making such election will
have all such amounts automatically reinvested by State Street, as the Plan
agent, in whole or fractional shares of the Fund, as the case may be.
 
     If the Directors of the Fund declare a distribution payable either in
shares or in cash, as shareholders may have elected, then nonparticipants in the
Plan will receive cash and participants in the Plan will receive the equivalent
in shares determined as follows: Whenever the market price of the shares on the
record date for the distribution is equal to or exceeds their net asset value,
participants will be issued shares at the higher of net asset value or 95% of
the closing market price of the shares on the NYSE on the previous trading day.
If the net asset value of shares at such time exceeds the market price of
shares, or if the Fund should declare a distribution payable only in cash, State
Street will, as agent for the participants, buy shares in the open market, on
the NYSE or elsewhere, for the participants' account. If, before State Street
has completed its purchases, the market price exceeds the net asset value of the
shares, State Street is permitted to cease purchasing the shares in the open
market and the Fund may issue the remaining shares at a price equal to the
higher of net asset value or 95% of the then market price. State Street will
apply all cash received as a distribution to purchase shares on the open market
as soon as practicable after the payment date of such distribution, but in no
event later than 30 days after such date, except where necessary to comply with
applicable provisions of the Federal securities laws.
 
                                       28
<PAGE>   33
 
     Participants in the Plan have the option of making additional cash payments
monthly to State Street for investment in the shares. Such payments may be made
in any amount from $100 to $3,000. State Street will use all such payments
received from participants to purchase shares on the open market on or about the
fifteenth day of each month (or the closest business day thereto, if a weekend
or holiday). To avoid unnecessary cash accumulations, and also to allow ample
time for receipt and processing by State Street, it is suggested that
participants send voluntary cash payments to State Street by the fifth day of
the month for which a voluntary purchase is desired. A participant may withdraw
a voluntary cash payment by written notice, if the notice is received by State
Street at least 48 hours before such payment is to be invested.
 
     State Street maintains all shareholder accounts in the Plan and furnishes
written confirmations of all transactions in the account, including information
needed by shareholders for personal and tax records. Shares in the account of
each Plan participant will be held by State Street in non-certificated form in
the name of the participant, and each shareholder's proxy will include those
shares purchased pursuant to the Plan.
 
     There is no charge to participants for reinvesting distributions or
voluntary cash payments. State Street's fees for the handling of the
reinvestment of distributions will be paid by the Fund.
 
     There will be no brokerage charges with respect to shares issued directly
by the Fund as a result of distributions payable either in stock or in cash.
However, each participant will pay a pro-rata share of brokerage commissions
incurred with respect to State Street's open market purchases in connection with
the reinvestment of distributions as well as from voluntary cash payments. With
respect to purchases from voluntary cash payments, State Street will charge each
participant a pro-rata share of the brokerage commissions. Brokerage charges for
purchasing small amounts of stock for individual accounts through the Plan are
expected to be less than the usual brokerage charges for such transactions, as
State Street will be purchasing shares for all participants in blocks and
prorating the lower commission thus attainable. State Street may use its
affiliates and/or affiliates of the Investment Adviser for all trading activity
relative to the Plan on behalf of Plan participants. Such affiliates will
receive a commission in connection with such trading transactions.
 
     If a shareholder desires to discontinue his or her participation in the
Plan, the shareholder may either (i) request State Street to sell part or all of
the shares in the account and remit the proceeds to the shareholder, net of any
brokerage commissions, or (ii) the shareholder may receive a certificate for the
appropriate number of full shares in the account, along with a check in payment
for any fractional shares.
 
     Although many brokers do participate in the Plan on behalf of their
customers, a participant in the Plan who does change his or her broker may not
be able to transfer the shares to another broker and continue to participate in
the Plan.
 
     The automatic reinvestment of distributions will not relieve participants
of any income tax that may be payable on such distributions.
 
     Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan as
applied to any voluntary cash payments made and any dividend or distribution
paid subsequent to written notice of the change sent to the members of the Plan
at least 90 days before the record date for such distribution. The Plan also may
be amended or terminated by State Street, with the Fund's prior written consent,
on at least 90 days' written notice to participants in the Plan. All
correspondence concerning the Plan should be directed to State Street at P.O.
Box 8040, Boston, MA 02266-8040.
 
                          DESCRIPTION OF COMMON STOCK
 
     The authorized capital stock of the Fund consists of 500,000,000 shares of
Common Stock, par value $0.001 per share, of which 79,017,765 shares were
outstanding as of April 13, 1998. The Shares when issued, will be fully paid and
nonassessable. All shares of Common Stock are equal as to dividends, assets and
voting privileges and have no conversion, preemptive or exchange rights. In the
event of liquidation, each share of Common Stock is entitled to its proportion
of the Fund's assets after payment of debts and expenses.
 
                                       29
<PAGE>   34
 
Shareholders are entitled to one vote per share. All voting rights for directors
are non-cumulative, which means that the holders of more than 50% of the shares
of common stock can elect 100% of the directors if they choose to do so, and, in
such event, the holders of the remaining shares of common stock will not be able
to elect any directors. The Fund's outstanding shares of Common Stock are, and
the Shares offered hereby will be, listed on the NYSE and PCX under the symbol
"ZTR."
 
     The Fund has no present intention of offering additional shares beyond this
Offering, except that additional shares may be issued under the Distribution
Reinvestment and Cash Purchase Plan. See "Distributions; Distribution
Reinvestment and Cash Purchase Plan." Other offerings of its Common Stock, if
made, will require approval of the Fund's Board of Directors. Any additional
offering will be subject to the requirements of the 1940 Act that shares may not
be sold at a price below the then current net asset value (exclusive of
underwriting discounts and commissions) except in certain circumstances,
including in connection with an offering to existing shareholders or with the
consent of a majority of the Fund's outstanding shares.
 
REPURCHASE OF SHARES; TENDER OFFERS
 
     The Fund is authorized to repurchase its shares on the open market when the
shares are trading at a discount from net asset value, and the Fund may incur
debt to refinance share repurchase transactions. In addition, pursuant to the
1940 Act, the Fund retains the right to repurchase its shares under other
circumstances on a securities exchange or such other open market designated by
the Commission (provided that the Fund has informed shareholders within the
preceding six months of its intention to repurchase such shares), by a tender
offer open to all the Fund's shareholders, or as otherwise permitted by the
Commission. When a repurchase of Fund shares is to be made that is not to be
effected on a securities exchange or such an open market or by the making of a
tender offer, the 1940 Act provides that certain conditions must be met
regarding, among other things, distribution of net income, identity of the
seller, price paid, brokerage commissions, prior notice to shareholders of an
intention to purchase shares and purchasing in a manner on a basis which does
not discriminate unfairly against the other shareholders indirectly through
their interest in the Fund. The Fund may incur debt to finance share repurchase
transactions (see "Investment Restrictions" in the SAI).
 
     When the Fund repurchases its shares for a price below their net asset
value, the net asset value of the shares that remain outstanding will be
enhanced, but this does not necessarily mean that the market price of those
outstanding shares will be affected, either positively or negatively. The Fund
has not repurchased any shares of its Common Stock.
 
     Since the Fund's inception in 1988, the Board of Directors has maintained a
policy pursuant to which the Board of Directors considers the making of tender
offers of the Fund each quarter during periods when the Fund's shares are
trading at a discount from net asset value. The Board may at any time, however,
decide that the Fund should not make tender offers. The net asset value at which
shares may be tendered will be established at the close of business on the last
day the tender offer is open. Since the Fund's inception, however, the Fund has
not made any tender offers for the shares of its Common Stock.
 
     It should be recognized that any acquisition of shares by the Fund (whether
through a share repurchase or a tender offer) will decrease the total assets of
the Fund and therefore have the effect of increasing the Fund's expense ratio.
Furthermore, if the Fund borrows to finance share repurchases or tender offers,
interest on such borrowing will reduce the Fund's net investment income. If the
Fund must liquidate a portion of its investment portfolio in connection with a
share repurchase or tender offer, such liquidation might be at a time when
independent investment judgment might not dictate such action and, accordingly,
may increase the Fund's portfolio turnover and make it more difficult for the
Fund to achieve its investment objective.
 
     Each person tendering shares will pay to the Fund a reasonable service
charge to help defray certain costs, including the processing of tender forms,
effecting payment, postage and handling. Any such service charge will be paid
directly by the tendering shareholder and will not be deducted from the proceeds
of the purchase. The Fund's transfer agent will receive the fee as an offset to
these costs. The Fund expects the cost to the Fund of effecting a tender offer
will exceed the aggregate of all service charges received from those who
                                       30
<PAGE>   35
 
tender their shares. Costs associated with the tender will be charged against
capital. During the pendency of any tender offer, shareholders may ascertain the
net asset value of the Fund's shares by calling a telephone number as provided
in any tender offer materials.
 
PROVISION FOR CONVERSION TO OPEN-END FUND
 
     If during any fiscal quarter beginning on or after January 1, 1990, the
Fund's shares trade, on the principal securities exchange on which they are
traded, at an average discount from net asset value of 10% or more (determined
on the basis of the discount as of the end of the last trading day in each week
during such quarter), the Fund's Articles of Incorporation require the Board of
Directors to submit to shareholders a proposal to convert the Fund to an
open-end investment company (the "Conversion Proposal"). The Fund's shares have
not traded at an average discount from net asset value of 10% or more during any
quarter since the Fund's inception. Thus, the Fund has not submitted any
Conversion Proposal to its shareholders. Approval of a Conversion Proposal would
require the affirmative vote of a majority of the outstanding shares of the Fund
entitled to be voted thereon. The Fund's Articles of Incorporation provide,
however, that a Conversion Proposal need not be submitted to shareholders with
respect to a quarter if a Conversion Proposal was submitted to shareholders with
respect to the immediately preceding quarter.
 
     If the Fund converted to an open-end investment company, its shareholders
could require the company to redeem their shares at any time (except in certain
circumstances as authorized by the 1940 Act) at the next determined net asset
value of such shares, less such redemption charges, if any, as might be in
effect at the time of redemption, and such redemption payment must be made
within seven days. This may require changes in the Fund's portfolio management,
since such redemption requests could require the Fund's liquidation of a portion
of its investment portfolio at a time when independent investment judgment might
not dictate such action and, accordingly, may increase the Fund's portfolio
turnover and make it more difficult for the Fund to achieve its investment
objective. In addition, if the Fund converted to an open-end investment company,
its shares would no longer be listed on any stock exchange, and certain of the
Fund's expenses (including transfer agency and shareholder services expenses)
would be greater than those that would be incurred by a closed-end investment
company.
 
     In the event the Fund's shareholders did not approve a proposal to convert
the Fund to an open-end investment company, the Fund would continue as a
closed-end investment company, but pursuant to the Fund's Articles of
Incorporation, the Board of Directors would be required to submit to the Fund's
shareholders a subsequent Conversion Proposal with respect to any subsequent
quarter during which there was an average discount of 10% or more from net asset
value, unless the Conversion Proposal had been submitted to shareholders with
respect to the immediately preceding quarter. The Fund cannot predict whether
any open market repurchases or tender offer purchases of its shares made while
the Fund is a closed-end investment company would decrease the discount from net
asset value. To the extent that any such open market repurchases or tender offer
purchases decreased the average discount from net asset value to below 10% for a
fiscal quarter, the Fund would not be required to submit to its shareholders the
Conversion Proposal with respect to such quarter.
 
SPECIAL VOTING PROVISIONS
 
     The Fund has provisions in its Articles of Incorporation and By-Laws
(collectively, the "Charter Documents") that could have the effect of limiting
the ability of other entities or persons to acquire control of the Fund, to
cause it to engage in certain transactions or to modify its structure. The Board
of Directors is divided into three classes. At the annual meeting of
shareholders each year, the term of one class will expire and directors will be
elected to serve in that class for terms of three years. This provision could
delay for up to two years the replacement of a majority of the Board of
Directors.
 
     The maximum number of Directors (twelve) may be increased, or a Director
may be removed from office, only by the affirmative vote of the holders of at
least 75% of the shares of the Fund entitled to be voted for the election of
Directors. In addition, the affirmative vote of the holders of 75% of the
outstanding shares of the Fund is required to authorize the conversion of the
Fund from a closed-end to an open-end investment
 
                                       31

company (except pursuant to the Conversion Proposal described above), to amend
certain of the provisions of the Articles of Incorporation or generally to
authorize any of the following transactions:
 
          (i) merger or consolidation or statutory share exchange of the Fund
     with or into any other corporation;
 
          (ii) a sale of all or substantially all of the Fund's assets (other
     than in the regular course of the Fund's investment activities); or
 
          (iii) a liquidation or dissolution of the Fund,
 
unless such action has been approved, adopted or authorized by the affirmative
vote of two-thirds of the total number of Directors fixed in accordance with the
By-Laws, in which case the affirmative vote of a majority of the Fund's
outstanding shares is required. Such 75% voting requirements described above,
which are greater than the minimum requirements under Maryland law or the Act,
can only be changed by a similar 75% vote. Reference is made to the Charter
Documents of the Fund, on file with the Commission, for the full text of these
provisions. See "Further Information."
 
     The provisions of the Charter Documents described above and the Fund's
right to repurchase or make a tender offer for shares of its common stock could
have the effect of depriving the owners of shares of opportunities to sell their
shares at a premium over prevailing market prices, by discouraging a third party
from seeking to obtain control of the Fund in a tender offer or similar
transaction. See "Repurchase of Shares" and "Tender Offers."
 
                                    TAXATION
 
FEDERAL TAXATION OF THE FUND AND ITS DISTRIBUTIONS
 
     The Fund has qualified and elected to be treated, and intends to continue
to qualify and be treated, as a regulated investment company under the Internal
Revenue Code of 1986, as amended (the "Code"). The Fund currently intends to
distribute all or substantially all its investment company taxable income (all
taxable income and net short-term capital gains) and its net capital gain each
year, thereby avoiding the imposition on the Fund of Federal income and excise
taxes on such distributed income and gain. Such distributions from investment
company taxable income will be taxable as ordinary income to shareholders of the
Fund who are subject to tax, and the Fund's capital gain distributions will be
taxable as capital gain to such shareholders. For non-corporate U.S.
shareholders, the Fund's capital gains distributions will be taxable at maximum
marginal Federal income tax rates of 28% as to the portion of such distributions
designated as a 28% rate gain distribution, and 20% as to the portion of such
distributions designated as a 20% rate gain distribution, respectively.
Shareholders that are not subject to tax on their income generally will not be
required to pay tax on amounts distributed to them. Notwithstanding the above,
the Fund may decide to retain all or part of any net capital gain for
reinvestment. After the end of each taxable year, the Fund will notify
shareholders of the Federal income tax status of any distributions, or deemed
distributions, made by the Fund during such year. For a discussion of certain
income tax consequences to shareholders of the Fund, see "Taxation" in the SAI.
 
FEDERAL INCOME TAX CONSEQUENCES RELATING TO THE OFFER
 
     The following discussion describes certain United States Federal income tax
consequences of the Offer generally applicable to citizens or residents of the
United States and U.S. trusts, estates, corporations and any other person who
would be subject to U.S. Federal income tax upon the sale or exchange of Common
Stock acquired upon the exercise of Rights ("U.S. Shareholders"). This summary
is intended to be descriptive only and does not purport to be a complete
analysis or listing of all potential tax effects relevant to the ownership of
Rights or Common Stock. Additionally, this summary does not specifically address
the U.S. Federal income tax consequences that might be relevant to holders of
Rights or Common Stock entitled to special treatment under the U.S. Federal
income tax laws, such as individual retirement accounts and other tax deferred
accounts, financial institutions, life insurance companies and tax-exempt
organizations, and does not discuss the effect of state, local and other tax
laws. Further, this summary is based on interpretations of existing law as
                                       32
<PAGE>   37
 
of the date of this Prospectus as contained in the Code, applicable current and
proposed Treasury Regulations, judicial decisions and published administrative
positions of the Internal Revenue Service, all of which are subject to change
either prospectively or retroactively.
 
     U.S. Shareholders who receive Rights pursuant to the Offer will not
recognize taxable income for U.S. Federal income tax purposes upon their receipt
of the Rights. If Rights issued to a U.S. Shareholder expire without being sold
or exercised, no basis will be allocated to such Rights, and such Shareholder
will not recognize any gain or loss for U.S. Federal income tax purposes upon
such expiration.
 
     The tax basis of a U.S. Shareholder's Common Stock will remain unchanged
and the shareholder's basis in the Rights will be zero, unless such U.S.
Shareholder affirmatively and irrevocably elects (in a statement attached to
such shareholder's U.S. Federal income tax return for the year in which the
Rights are received) to allocate the basis in the Common Stock between such
Common Stock and the Rights in proportion to their respective fair market values
on the date of distribution.
 
     A U.S. Shareholder who exercises Rights will not recognize any gain or loss
for U.S. Federal income tax purposes upon the exercise. The basis of the newly
acquired Common Stock will equal the Subscription Price paid for the Common
Stock (plus the basis, if any, allocated to the Rights in the manner described
in the immediately preceding paragraph). Upon a sale or exchange of the Common
Stock so acquired, the Shareholder will recognize gain or loss measured by the
difference between the proceeds of the sale or exchange and the cost basis of
such Common Stock. Assuming the U.S. Shareholder holds the Common Stock as a
capital asset, any gain or loss realized upon its sale will generally be treated
as a capital gain or loss, which gain or loss will be short-term, mid-term or
long-term, depending on the length of the U.S. Shareholder's holding period for
such Common Stock. However, it currently appears that any loss recognized upon
the sale of shares of Common Stock with a tax holding period of 6 months or less
will be treated as a long-term capital loss to the extent of any capital gain
distribution previously received by the U.S. Shareholder with respect to such
shares, and a loss may be disallowed under wash sale rules to the extent that
the U.S. Shareholder purchases additional Common Stock (including by
reinvestment of distributions) within 30 days before or after the sale date. The
holding period for Common Stock acquired upon the exercise of Rights will begin
on the date of exercise of the Rights.
 
     A U.S. Shareholder may be subject to backup withholding at the rate of 31%
with respect to Fund distributions and gross proceeds from the sale or exchange
of Common Stock (if the Fund is the payor) unless such U.S. Shareholder (a) is a
corporation or comes within certain other exempt categories and, when required,
demonstrates and/or certifies this fact, or (b) provides a correct taxpayer
identification number, along with certain required certifications, and otherwise
complies with applicable requirements of the backup withholding rules. U.S.
Shareholders who choose to transfer their Common Stock and who do not provide
the appropriate withholding agent with their correct taxpayer identification
number in the manner required may be subject to penalties imposed by the
Internal Revenue Service. Any amount withheld under these rules is not an
additional tax; it will be creditable against the U.S. Shareholder's U.S.
Federal income tax liability.
 
     This summary is not intended to be, nor should it be, construed as legal or
tax advice to any current holder of Common Stock. Further, because the U.S.
Federal income tax consequences of the Offer may vary depending upon the
particular circumstances of each shareholder of the Fund and other facts, and
because this summary is not exhaustive of all possible U.S. Federal income tax
considerations (such as situations involving taxpayers who are dealers in
securities or whose functional currency is not the U.S. dollar), the Fund's
shareholders are urged to consult their own tax advisors to determine the U.S.
Federal income tax consequences to them of the Offer and their ownership of
Rights and Common Stock. In addition, such shareholders are urged to consult
their own tax advisors in determining the U.S. state and local tax consequences
to them of the Offer and such ownership. See "Taxation" in the SAI.
 
                           DISTRIBUTION ARRANGEMENTS
 
     Merrill Lynch, Pierce, Fenner & Smith Incorporated, New York, New York,

Agreement between the Fund and the Dealer Manager, dated April 14, 1998 (the
"Dealer Manager Agreement"), the Dealer Manager will provide financial advisory,
marketing and soliciting services in connection with the Offer. The Fund has
agreed to pay the Dealer Manager a fee for financial advisory and marketing
services in connection with the Offer equal to 1.25% of the aggregate
Subscription Price for the Shares issued pursuant to the exercise of the Rights
and the Over-Subscription Privilege (the "Dealer Manager Fee"). The Fund has
also agreed to pay the Dealer Manager, and other broker-dealers soliciting the
exercise of Rights, solicitation fees equal to 2.50% of the Subscription Price
per Share for each Share issued pursuant to the exercise of the Rights and the
Over-Subscription Privilege (the "Solicitation Fees"). Solicitation Fees will be
paid to the broker-dealer designated on the related Subscription Certificate,
provided that such designated broker-dealer has executed a confirmation
accepting the terms of the soliciting dealer agreement relating to the Offer or,
in the absence of such designation or confirmation, to the Dealer Manager. Zweig
Securities Corp. will be such designated broker-dealer with respect to Shares
issued to participants in the Fund's Distribution Reinvestment and Cash Purchase
Plan, unless the participant designates otherwise on the related Subscription
Certificate.
    
 
     The Fund has also agreed to reimburse the Dealer Manager for its
out-of-pocket expenses up to $82,500 incurred in connection with the Offer. In
addition, the Fund has agreed to pay a fee to each of the Subscription Agent and
Information Agent estimated to be $245,000 and $42,500, respectively, which
includes reimbursement for their out-of-pocket expenses related to the Offer.
The Fund and the Investment Adviser have agreed to indemnify the Dealer Manager
against certain liabilities, including liabilities under the Securities Act.
 
     The Fund has agreed not to offer or sell, or enter into any agreement to
sell, any equity or equity related securities of the Fund for a period of 180
days after the date of the Dealer Manager Agreement without the prior written
consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated, except for the
Shares and Common Stock issued in reinvestment of distributions.

                        INVESTMENT OBJECTIVE AND POLICIES


         The Fund's investment objective is to seek the highest total return,
consisting of capital appreciation and current income, consistent with the
preservation of capital. The Fund will invest up to 65% of its total assets in
U.S. Government Securities, non-convertible debt securities of domestic issuers
rated among the two highest rating categories of either Moody's Investors
Services, Inc. or Standard & Poor's Corporation (or of comparable quality), and
certain Foreign Government Securities, and up to 35% of its total assets in
equity securities. The Fund may, however, under certain circumstances, invest up
to 75% of its total assets in equity securities. The extent of the Fund's
investment in debt and equity securities will be determined primarily on the
basis of market timing techniques developed by Dr. Martin E. Zweig, the
President of the Fund's Investment Adviser, and his staff. While the Investment
Adviser seeks to reduce the risks associated with investing in debt and equity
securities by using these techniques, the risk of investment in debt and equity
securities cannot be eliminated. There is no assurance that the Fund will
achieve its investment objective. See "Investment Objective and Policies" in the
Prospectus.

         The following describes certain investment strategies in which the
Investment Adviser may engage, on behalf of the Fund, each of which may involve
certain special risks.

FUTURES CONTRACTS AND RELATED OPTIONS

         Upon entering into a futures contract, the Fund will initially be
required to deposit with the custodian an amount of initial margin using cash or
U.S. Treasury bills equal to approximately 2% to 5% of the contract amount. The
nature of initial margin in futures transactions is different from that of
margin in securities transactions in that the futures contract initial margin
does not involve the borrowing of funds by customers to finance the
transactions. Rather, the initial margin is in the nature of a performance bond
or good faith deposit on the contract which is returned to the Fund upon
termination of the futures contract, assuming all contractual obligations have
been satisfied. In addition to initial margin, the Fund is required to deposit
cash, liquid debt obligations, liquid equity securities or cash equivalents in
an amount equal to the notional value of all long futures contracts, less the
initial margin amount, in a segregated account with the custodian to ensure that
the use of such futures contracts is not leveraged. If the value of the
securities placed in the segregated account declines, additional securities,
cash or cash equivalents must be placed in the segregated account so that the
value of the account will at least equal the amount of the Fund's commitments
with respect to such futures contracts.

         Subsequent payments, called maintenance margin, to and from the broker,
will be made on a daily basis as the price of the underlying security
fluctuates, making the long and short positions in the futures contract more or
less valuable, a process known as "marking to the market." For example, when the
Fund has purchased a futures contract and the price of the underlying security
has risen, that position will have increased in value and the Fund will receive
from the broker a maintenance margin payment equal to that increase in value.
Conversely, when the Fund has purchased a futures contract and the price of the
underlying security has declined, the position would be less valuable and the
Fund would be required to make a maintenance margin payment to the broker. At
any time prior to expiration of the futures contract, the Fund may elect to
close the position by taking an opposite position which will operate to
terminate the Fund's position in the futures contract. A final determination of
maintenance margin is then made, additional cash is required to be paid by or
released to the Fund, and the Fund realizes a loss or a gain.


                                       1
<PAGE>   44
         While futures contracts based on securities provide for the delivery
and acceptance of securities, such deliveries and acceptances are very seldom
made. Generally, the futures contract is terminated by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument with the same
delivery date. If the price in the sale exceeds the price in the offsetting
purchase, the Fund immediately is paid the difference and thus realizes a gain.
If the offsetting purchase price exceeds the sales price, the Fund pays the
difference and realizes a loss. Similarly, the closing out of a futures contract
purchase is effected by the Fund entering into a futures contract sale. If the
offsetting sale price exceeds the purchase price, the Fund realizes a gain, and
if the purchase price exceeds the offsetting price, the Fund realizes a loss.

         There are several risks in connection with the use of futures contracts
as a hedging device. One risk arises due to the imperfect correlation between
movements in the price of the futures contracts and movements in the price of
the subject of the hedge. The price of the futures contract may move more than
or less than the price of the securities being hedged.

         If the price of the futures contracts moves less than the price of the
securities hedged, the hedge will not be fully effective, but, if the price of
the securities being hedged has moved in an unfavorable direction, the Fund
would be in a better position than if it had not hedged at all. If the price of
the securities being hedged has moved in a favorable direction, this advantage
will be partially offset by the movement in the price of the futures contract.
If the price of the futures contract moves more than the price of the security,
the Fund will experience either a loss or gain on the futures which will not be
completely offset by movements in the prices of the securities which are the
subject of the hedge.

         To compensate for the imperfect correlation of such movements in price,
the Fund may buy or sell futures contracts in a greater dollar amount than the
dollar amount of the securities being hedged if the historical volatility of the
prices of such securities have been greater than the historical volatility of
the futures contracts. Conversely, the Fund may buy or sell fewer futures
contracts if the historical volatility of the prices of the securities being
hedged is less than the historical volatility of the futures contracts.

         It is also possible that, where the Fund has sold futures to hedge its
portfolio against a decline in the market, the market may advance and the value
of securities held in the Fund's portfolio may decline. If this occurred, the
Fund would lose money on the futures contracts and also experience a decline in
value in its portfolio securities. However, while this could occur for a very
brief period or to a very small degree, over time the value of a diversified
portfolio will tend to move in the same direction as the futures contracts.

         Where futures are purchased to hedge against a possible increase in the
cost of securities before the Fund is able to invest its cash (or cash
equivalents) in an orderly fashion, it is possible that the market may decline
instead; if the Fund then concludes not to invest in the relevant securities at
that time because of concern as to possible further market decline or for other
reasons, the Fund will realize a loss on the futures contract that is not offset
by a reduction in the price of securities purchased.

         Another risk arises because the market prices of futures contracts may
be affected by certain factors. First, all participants in the futures market
are subject to initial margin and maintenance margin requirements. Rather than
meeting maintenance margin requirements, investors may close futures contracts
through offsetting transactions which could distort the normal relationship
between the securities and futures markets. Second, from the point of view of
speculators, the margin requirements in the futures market are less onerous than


                                       2
<PAGE>   45
margin requirements in the securities market. Therefore, increased participation
by speculators in the futures market may also cause temporary price distortions.

         Due to the possibility of price distortion in the futures market and
because of the imperfect correlation between movements in securities and
movements in the prices of futures contracts, a correct forecast of market
trends by the Investment Adviser may still not result in a successful hedging
transaction over a very short period of time.

         The hours of trading for futures contracts may not conform to the hours
during which the underlying securities are traded. To the extent that the
futures contracts markets close after the markets for the underlying securities,
significant price movements can take place in the futures contracts markets that
cannot be reflected in the markets of the underlying securities.

         Positions in futures contracts may be closed out only on an exchange or
board of trade which provides a secondary market for such futures. Although the
Fund intends to purchase or sell futures only on exchanges or boards of trade
where there appears to be an active secondary market, there is no assurance that
a liquid secondary market on an exchange or board of trade will exist for any
particular contract or at any particular time. In such event, it may not be
possible to close a futures position and, in the event of adverse price
movements, the Fund would continue to be required to make daily cash payments of
maintenance margin. However, in the event futures contracts have been used to
hedge portfolio securities, such securities will not be sold until the futures
contracts can be terminated. In such circumstances, an increase in the price of
the securities, if any, may partially or completely offset losses on the futures
contract. However, as described above, there is no guarantee that the price of
the securities will, in fact, correlate with the price movements in the futures
contract and thus provide an offset to losses on a futures contract. The Fund
does not intend to devote more than 5% of its net assets as initial margin or
option premiums for futures transactions.

SECURITY AND STOCK INDEX OPTIONS

         When the Fund writes an option, an amount equal to the premium received
by the Fund is recorded as an asset and as an offsetting liability. The amount
of the liability is "marked-to-market" daily to reflect the current market value
of the option, which is the last sale price on the principal exchange on which
such option is traded or, in the absence of a sale, the mean between the latest
bid and offering prices. If an option written by the Fund expires, or the Fund
enters into a closing purchase transaction, the Fund will realize a gain (or, in
the latter case, a loss, if the cost of a closing transaction exceeds the
premium received) and the liability related to such option will be extinguished.

         The premium paid by the Fund for the purchase of a put option (its
cost) is recorded initially as an investment, the value of which is subsequently
adjusted to the current market value of the option. If the current market value
of a put option exceeds its premium, the excess represents unrealized
appreciation; conversely, if the premium exceeds the current market value, the
excess represents unrealized depreciation. The current market value of an option
purchased by the Fund equals the option's last sale price on the principal
exchange on which it is traded or, in the absence of a sale, the mean between
the latest bid and offering prices.

         An option position may be closed out only on an exchange which provides
a secondary market for an option of the same series. Although the Fund generally
will purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an


                                       3
<PAGE>   46
exchange will exist for any particular option, or at any particular time, and
for some options no secondary market on an exchange may exist. In such event, it
might not be possible to effect closing transactions in particular options, with
the result that the Fund would have to exercise its options in order to realize
any profit and would incur transaction costs on the sale of underlying
securities pursuant to the exercise of put options. If the Fund, as a covered
call option writer, is unable to effect a closing purchase transaction in a
secondary market, it will not be able to sell the underlying security until the
option expires or it delivers the underlying security upon exercise.

         Reasons for the absence of a liquid secondary market on an exchange
include the following: (a) there may be insufficient interest in trading certain
options; (b) restrictions may be imposed by an exchange on opening transactions
or closing transactions or both; (c) trading halts, suspensions or other
restrictions may be imposed with respect to particular classes or series of
options or underlying securities; (d) unusual or unforeseen circumstances may
interrupt normal operations on an exchange; (e) the facilities of an exchange or
the Options Clearing Corporation (the "OCC" ) may not at all times be adequate
to handle current trading volume; or (f) one or more exchanges might, for
economic or other reasons, decide or be compelled at some future date to
discontinue the trading of options (or a particular class or series of options),
in which event the secondary market on that exchange (or in that class or series
of options) would cease to exist, although outstanding options on that exchange
that had been issued by the OCC as a result of trades on that exchange would
continue to be exercisable in accordance with their terms.

         In addition, there is no assurance that higher-than-anticipated trading
activity or other unforeseen events might not, at times, render certain of the
facilities of the OCC inadequate, and thereby result in the institution by an
exchange of special procedures which may interfere with the timely execution of
customers' orders.

         The amount of the premiums which the Fund may pay or receive may be
adversely affected as new or existing institutions, including other investment
companies, engage in or increase their option purchasing and writing activities.

         In the event of a shortage of the underlying securities deliverable on
exercise of a listed option, the OCC has the authority to permit other,
generally comparable securities to be delivered in fulfillment of option
exercise obligations. If the OCC exercises its discretionary authority to allow
such other securities to be delivered, it may also adjust the exercise prices of
the affected options by setting different prices at which otherwise ineligible
securities may be delivered. As an alternative to permitting such substitute
deliveries, the OCC may impose special exercise settlement procedures.

CLOSED-END INVESTMENT COMPANIES

         When the Fund invests in other closed-end investment companies, the
investments made by such other investment companies will be effected by
independent investment managers, and the Fund will have no control over the
investment management, custodial arrangements or operations of any investments
made by such investment managers. Some of the funds in which the Fund may invest
could also incur more risks than would be the case for direct investments made
by the Fund. For example, they may engage in investment practices that entail
greater risks or invest in companies whose securities and other investments are
more volatile. In addition, the funds in which the Fund invests may or may not
have the same fundamental investment limitations as those of the Fund itself.
While a potential benefit of investing in closed-end investment companies would
be


                                       4
<PAGE>   47
to realize value from a decrease in the discount from net asset value at which
some closed-end funds trade, there is also the potential that such discount
could grow, rather than decrease.

         By investing in investment companies indirectly through the Fund, a
shareholder of the Fund will bear not only a proportionate share of the expenses
of the Fund (including operating costs and investment advisory and
administrative fees) but also, indirectly, similar expenses of the investment
companies in which the Fund invests. Pursuant to the Fund's investment
restrictions and current law, the Fund will not (i) own more than 3% of the
voting securities of any one investment company; (ii) invest more than 5% of its
assets in the securities of any one investment company; or (iii) invest more
than 10% of its assets in securities issued by investment companies.

FOREIGN SECURITIES

         The Fund may invest up to 10% of its total assets in Foreign Government
Securities and up to 10% of its total assets in equity securities of foreign
issuers. Investments in foreign securities offer potential benefits not
available through investment solely in securities of domestic issuers. Foreign
securities offer the opportunity to invest in foreign issuers that appear to
have growth potential, or in foreign countries with economic policies or
business cycles different from those of the United States, or to reduce
fluctuations in portfolio value by taking advantage of foreign markets that do
not move in a manner parallel to United States markets. The Fund may also enter
into foreign currency transactions in connection with its investment activity in
foreign securities.

         Investments in foreign securities present special additional risks and
considerations not typically associated with investments in domestic securities.
Foreign investments may be affected by changes in foreign currency rates and
exchange control regulations. There may be less information available about a
foreign company than a domestic company, and foreign companies may not be
subject to accounting, auditing and reporting standards and requirements
comparable to those applicable to domestic companies. Foreign securities may be
less liquid and subject to greater price volatility than domestic securities.
Foreign brokerage commissions and custodial fees are generally higher than those
in the United States. The foreign markets also have different clearance and
settlement procedures and in certain markets there have been times when
settlements have been unable to keep pace with the volume of securities
transactions, making it difficult to conduct such transactions. Delays or
problems with settlements might affect the liquidity of the Fund's portfolio and
might adversely affect the Fund's performance. Foreign investments may also be
subject to local economic or political risks, political instability and possible
nationalization of issuers or expropriation of their assets which might
adversely affect the Fund's ability to realize or liquidate its investment in
such securities. Furthermore, some foreign securities are subject to brokerage
taxes levied by foreign governments, which have the effect of increasing the
cost of such investment and reducing the realized gain or increasing the
realized loss on such securities at the time of sale. Furthermore, legal
remedies for defaults and disputes may have to be pursued in foreign courts
whose procedures differ substantially from those of U.S. courts. In the event of
a default in payment on foreign securities, the Fund may incur increased costs
to obtain and/or to enforce a judgment against the foreign issuer (or the other
parties to the transaction) in the United States or abroad, and no assurance can
be given that the Fund will be able to collect on any such judgment.

         Income earned or received by the Fund from sources within foreign
countries may be reduced by withholding and other taxes imposed by such
countries. Tax conventions between certain countries and the United States,
however, may reduce or eliminate such taxes. Any such taxes paid by the Fund
will reduce its


                                       5

<PAGE>   48
net income available for distribution to shareholders.

         Pursuant to the provisions of Rule 17f-5 under the 1940 Act, the Fund's
Board of Directors has delegated to the Fund's Custodian, The Bank of New York,
as the Fund's Foreign Custody Manager the responsibilities for selecting and
monitoring any foreign custodians that may be used in connection with the Fund's
investments in foreign securities. Pursuant to and subject to the terms and
conditions of the Foreign Custody Manager Agreement between The Bank of New York
and the Fund, The Bank of New York will, among other things, (i) determine that
the assets held by foreign custodians are subject to reasonable care, based on
the standards applicable to custodians in the relevant market in which such
foreign custodian operates, (ii) determine that the foreign custodial
arrangements are governed by a written contract that provides reasonable care
for the Fund's assets based on such standards, (iii) establish a system to
monitor the appropriateness of maintaining the Fund's assets with a particular
foreign custodian and any material changes in such contract, and (iv) report to
the Fund's Board of Directors with respect to the Fund's foreign custodial
arrangements.

SHORT SALES

         The Fund may from time to time make short sales of securities. A short
sale is a transaction in which the Fund sells a security it does not own in
anticipation of a decline in market price. The Fund may make short sales to
offset a potential decline in a long position or a group of long positions, or
if the Investment Adviser believes that a decline in the price of a particular
security or group of securities is likely. The Fund may also make short sales in
an attempt to maintain portfolio flexibility and facilitate the rapid
implementation of investment strategies if the Investment Adviser believes that
the price of a particular security or group of securities is likely to decline.

         When the Fund determines to make a short sale of a security, it must
borrow the security. The Fund's obligation to replace the security borrowed in
connection with the short sale will be fully secured by the proceeds from the
short sale retained by the broker and by cash or liquid securities deposited in
a segregated account with the Fund's custodian. The Fund may have to pay a
premium to borrow the security. The Fund must also pay any dividends or interest
payable on the security until the Fund replaces the security.

         If the price of the security sold short increases between the time of
the short sale and the time the Fund replaces the borrowed security, the Fund
will incur a loss, and if the price declines during this period, the Fund will
realize a capital gain. Any realized capital gain will be decreased, and any
incurred loss increased, by the amount of transaction costs and any premium,
dividend or interest which the Fund may have to pay in connection with such
short sale.

         In addition to the short sales described above, the Fund may make short
sales "against the box." A short sale "against the box" is a short sale where,
at the time of the short sale, the Fund owns or has the immediate and
unconditional right, at no added cost, to obtain the identical security. The
Fund would enter into such a transaction to defer a gain or loss for Federal
income tax purposes on the security owned by the Fund. Short sales against the
box are not subject to the collateral requirements described above or the
percentage limitations on short sales described below.

         The Fund may make a short sale only if, at the time the short sale is
made and after giving effect thereto, the market value of all securities sold
short is 25% or less of the value of its net assets and the market value of
securities sold short which are not listed on a national securities exchange
does not exceed 10% of the Fund's


                                       6
<PAGE>   49
net assets.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

         The Fund may from time to time purchase securities on a "when-issued"
or "delayed-delivery" basis whereby the Fund purchases a bond or stock with
delivery of the security and payment deferred to a future date. The money to
purchase such securities will be invested in other securities until the Fund
receives delivery. This could increase the possibility that the Fund's net asset
value would increase or decrease faster than would otherwise be the case.
Securities purchased on a when-issued or delayed-delivery basis may expose the
Fund to risk, since such securities may experience fluctuations in value (based
upon, in the case of bonds, the public's perception of the creditworthiness of
the issuer and changes, real or anticipated, in the level of interest rates)
prior to their time of delivery. In addition, the yield available in the market
when the delivery takes place actually may be higher than that obtained in the
transaction itself. At the time the Fund makes the commitment to purchase a
security on a when-issued or delayed-delivery basis, it will record the
transaction and reflect the value of the security less the liability to pay the
purchase price in determining the fund's net asset value. The value of the
security on the settlement date may be more or less than the price paid. No
interest accrues on the security between the time the Fund enters into the
commitment and the time the security is delivered. The Fund will establish a
segregated account with the Custodian in which it will maintain cash and
short-term high quality debt securities equal in value to commitments for
when-issued or delayed-delivery securities. Such segregated securities will be
"marked-to-market" daily. While when-issued or delayed-delivery securities may
be sold prior to the settlement date, it is intended that the Fund will purchase
such securities with the purpose of actually acquiring them unless a sale
appears desirable for investment reasons. The Fund is dependent on the other
party to successfully complete when-issued and delayed delivery transactions. If
such other party fails to complete its portion of the transaction, the Fund may
have lost a favorable investment opportunity. There is no limitation on the
percentage of the Fund's assets that may be invested in when-issued or
delayed-delivery securities.

                             INVESTMENT RESTRICTIONS

         The Fund has adopted the following fundamental policies which cannot be
changed without the approval of the holders of a majority of its outstanding
voting securities (as defined under "Investment Objective and Policies" in the
Prospectus). Except as otherwise noted, all percentage limitations set forth
below apply immediately after a purchase or initial investment, and any
subsequent change in any applicable percentage resulting from market
fluctuations does not require elimination of any security or other investment
from the portfolio. The Fund may not:

         1. With respect to 75% of its total assets, invest in securities of any
one issuer if immediately after and as a result of such investment more than 5%
of the total assets of the Fund, taken at market value, would be invested in the
securities of such issuer. This investment restriction does not apply to
investments in U.S. Government Securities.


                                       7
<PAGE>   50
         2. Purchase more than 10% of the outstanding voting securities, or any
class of securities, of any one issuer. This investment restriction does not
apply to investments in U.S. Government Securities.

         3. Purchase securities which would cause 25% or more of its total
assets at the time of such purchase to be concentrated in the securities of
issuers engaged in any one particular industry or group of related industries.
This investment restriction does not apply to investments in U.S. Government
Securities.

         4. Purchase or sell real estate; provided that the Fund may invest in
securities secured by real estate or real estate interests or issued by
companies which invest in real estate or real estate interests.

         5. Purchase any securities on margin. For purposes of this investment
restriction, the following do not constitute margin purchases: (i) effecting
short sales, to the extent permitted by 9. below, (ii) making margin deposits in
connection with any futures contracts or any options the Fund may purchase, sell
or write, or (iii) entering into any currency transactions.

         6. Lend any funds or other assets, except that the Fund may purchase
publicly distributed debt obligations (including repurchase agreements)
consistent with its investment objective and policies, and the Fund may make
loans of portfolio securities if such loans do not cause the aggregate amount of
all outstanding securities loans to exceed 33 1/3% of the Fund's total assets,
provided that the loan is collateralized by cash or cash equivalents or U.S.
Government Securities in an amount equal, on a daily basis, to the market value
of the securities loaned.

         7. Borrow money (through reverse repurchase agreements or otherwise),
except (i) for temporary emergency purposes in amounts not in excess of 5% of
the value of the Fund's total assets at the time the loan is made; or (ii) in an
amount not greater than 33 1/3% of the Fund's total assets.

         8. Issue senior securities, as defined in the 1940 Act, or mortgage,
pledge, hypothecate or in any manner transfer, as security for indebtedness, any
securities owned or held by the Fund except as may be necessary in connection
with borrowings mentioned in 7. above. For the purposes of this investment
restriction and 7. above, collateral or escrow arrangements with respect to the
making of short sales, writing of stock options, purchase of securities on a
forward commitment or delayed-delivery basis, and purchase of foreign currency
forward contracts and collateral arrangements with respect to margin for futures
contracts and foreign currency forward contracts or related options are not
deemed to be a pledge of assets and neither such arrangements nor the purchase
or sale of futures contracts, foreign currency forward contracts or related
options are deemed to be the issuance of a senior security.

         9. Make any short sales of securities, unless at the time the short
sale is made and after giving effect thereto, (i) the market value of all
securities sold short is 25% or less of the value of the Fund's total assets,
(ii) the market value of such securities sold short which are not listed on a
national securities exchange does not exceed 10% of the Fund's total assets,
(iii) the market value of all securities of any one issuer sold short does not
exceed 2% of the Fund's total assets, (iv) short sales are not made of more than
2% of the outstanding securities of one class of any issuer, and (v) the Fund
maintains collateral deposits consisting of cash or U.S. Government Securities
in a segregated account which, together with collateral deposited with the
broker-dealer, are at all times equal to 100% of the current market value of the
securities sold short. This investment restriction does not apply to short sales
"against the box." For the purposes of this investment restriction, sales


                                       8
<PAGE>   51
of securities on a when-issued or delayed-delivery basis are not considered to
be short sales.

         10. Underwrite securities of other issuers except insofar as it might
be deemed to be an underwriter for purposes of the Securities Act of 1933, as
amended, in the resale of any securities held in its own portfolio.

         11. Invest more than 10% of the Fund's total assets in securities that
at the time of purchase are subject to restrictions on disposition under the
Securities Act of 1933, as amended.

         12. Purchase or sell commodities or commodity or futures contracts or
options on commodity or futures contracts except in compliance with such rules
and interpretations of the Commodity Futures Trading Commission which exempt the
Fund from regulation as a commodity pool operator.

LIMITATION OF OFFICERS' AND DIRECTORS' LIABILITY

         The Fund's Articles of Incorporation limit the personal liability of
its Officers and Directors to the Fund and its shareholders for money damages to
the maximum extent permitted by the Maryland General Corporation Law.
Accordingly, a shareholder will be able to recover money damages against a
Director or Officer of the Fund only if he is able to prove that (a) the action,
or failure to act, by the Director or Officer was the result of active and
deliberate dishonesty which was material to the cause of action adjudicated in
the proceeding, (b) the Director or Officer actually received an improper
benefit or profit in money, property or services (in which case recovery is
limited to the actual amount of such improper benefit or profit), or (c) the
Director or Officer acted with willful misfeasance, bad faith, gross negligence,
or reckless disregard of the duties involved in the conduct of his or her
office. The limitation also does not apply to claims against Directors or
Officers arising out of their responsibilities under the Federal securities
laws. The Fund's Articles of Incorporation do not limit the right of the Fund or
any shareholder to sue for an injunction or any other nonmonetary relief in the
event of a breach of a Director's or Officer's duty of care or other breach of
duty or responsibility.


                                    EXPENSES

         For the fiscal years ended December 31, 1997, 1996 and 1995, the Fund's
expenses amounted to $6,761,578, $6,473,138 and $6,807,315, respectively.

         Expenses of the Offer will be charged to capital. The Fund's annual
expense ratio was 1.04%%, 1.03% and 1.10% of the Fund's net assets for the
fiscal years ended December 31, 1997, 1996 and 1995, respectively.



                      PORTFOLIO TRANSACTIONS AND BROKERAGE

         In the purchase and sale of portfolio securities for the Fund, the
Investment Adviser will seek the best combination of price (inclusive of
brokerage commissions) and execution, and, consistent with that policy, may give
consideration to the research, statistical and other services furnished by
brokers or dealers to the Investment Adviser for its use. The Investment Adviser
is also authorized to place orders with brokers who provide supplemental
investment, market research and security and economic analysis, although the use
of such brokers may result in a higher brokerage charge to the Fund than the use
of brokers selected on the basis of seeking the best combination of price
(inclusive of brokerage commissions) and execution for the same order. Brokerage
may be allocated entirely on the basis of net results to the Fund, including the
difficulty of the order and the reputation of the broker-dealer. Research and
analysis received by the Investment Adviser may benefit the Investment Adviser
and its affiliates in connection with their services to other clients, as well
as the Fund. Subject to the foregoing, the Fund may effect a portion of its
securities transactions through affiliated broker-dealers of the Investment
Adviser, including Zweig Securities Corp., a broker-dealer of which Eugene J.
Glaser, President of the Administrator and a Director of The Zweig Fund, Inc.,
is President, and Martin E. Zweig and Eugene J. Glaser are the shareholders. In
accordance with the provisions of Rule 17e-1 of the 1940 Act, the Fund's Board
of Directors has adopted certain procedures which are designed to provide that
brokerage commissions paid to Zweig Securities Corp. and any other affiliated
broker-dealer are reasonable and fair as compared to the brokerage commissions
received by other brokers in connection with comparable transactions


                                       12
<PAGE>   55
involving similar securities being purchased or sold on securities exchanges
during a comparable period of time. The Fund, however, has no obligation to deal
with Zweig Securities Corp. or any other broker-dealer in effecting portfolio
transactions.
   
         The Fund paid brokerage commissions of $567,917 to brokers for the year
ended December 31, 1997, of which $80,824 was paid to Zweig Securities Corp.,
representing 14.23% of the aggregate brokerage commissions paid by the Fund and
15.17% of the aggregate amount of transactions involving the payment of
commissions for such year. The Fund paid brokerage commissions of $744,349 to
brokers for the year ended December 31, 1996, of which $60,371 was paid to Zweig
Securities Corp , representing 8.11% of the aggregate brokerage commissions paid
by the Fund and 7.65% of the aggregate amount of transactions involving the
payment of commissions for such year The Fund paid brokerage commissions of
$780,000 to brokers for the year ended December 31, 1995, of which $124,269 was
paid to Watermark Securities, Inc., representing 15.93% of the aggregate
brokerage commissions paid by the Fund and 15.72% of the aggregate amount of
transactions involving the payment of commissions for such year. Martin E. Zweig
is a principal shareholder of Watermark Securities, Inc.
    
         A portion of the securities in which the Fund will invest may be traded
in the over-the-counter markets, and the Fund intends to deal directly with the
dealers who make markets in the securities involved, except in those
circumstances where better prices and execution are available elsewhere. Fixed
income securities purchased or sold on behalf of the Fund normally will be
traded in the over-the-counter market on a net basis (i.e. without a commission)
through dealers acting for their own account and not as brokers or otherwise
through transactions directly with the issuer of the instrument. Some fixed
income securities may be purchased and sold on an exchange or in
over-the-counter transactions conducted on an agency basis involving a
commission. Futures transactions generally will be effected through those
futures commission merchants the Fund believes will obtain the most favorable
results for the Fund.

         When the Fund and one or more accounts managed by the Investment
Adviser or its affiliates propose to purchase or sell the same security, the
available opportunities will be allocated in a manner the Investment Adviser
believes to be equitable. In some cases, this procedure may affect adversely the
price paid or received by the Fund or the size of the position purchased or sold
by the Fund. In other cases, coordination with transactions for other accounts
and the ability to participate in volume transactions could benefit the Fund.

PORTFOLIO TURNOVER

         The Fund's portfolio turnover rates for the fiscal years ended December
31, 1997, December 31, 1996 and December 31, 1995 were 104.7%, 147.2% and
179.8%, respectively. Portfolio turnover rate is calculated by dividing the
lesser of the Fund's annual sales or purchases of portfolio securities by the
monthly average value of securities in the portfolio during the year, excluding
portfolio securities the maturities of which at the time of acquisition were one
year or less. Portfolio turnover will not be a limiting factor in making
investment decisions, and the Fund's investment policies may result in portfolio
turnover substantially greater than that of other investment companies. A high
rate of portfolio turnover (over 100%) involves greater brokerage commission
expense, which must be borne by the Fund and its shareholders. A high rate of
portfolio turnover may also result in the realization of capital gains, and to
the extent that portfolio turnover results in the realization of net short-term
capital gains, such gains generally are taxed to shareholders at ordinary income
tax rates.


                                       13
<PAGE>   56
                                 NET ASSET VALUE

         The net asset value of the Fund's shares will be determined by the
Administrator as of the close of regular trading on the New York Stock Exchange,
on each day the Exchange is open for trading, by dividing the Fund's total
assets, less the Fund's total liabilities, by the total number of Shares
outstanding. Net asset value will be published weekly in a financial newspaper
of general circulation.

         Portfolio securities (including stock options) which are traded only on
stock exchanges will be valued at the last sale price. Securities traded in the
over-the-counter market which are National Market Systems securities will be
valued at the last sale price. Other over-the-counter securities will be valued
on the basis of the mean between the current bid and asked prices obtained from
market makers in such securities. Debt securities that mature in 60 days or less
will be valued at amortized cost, unless the Board of Directors determines that
such valuation does not constitute fair value. Debt securities that have an
original maturity of less than 61 days will be valued at their cost, plus or
minus amortized discount or premium, unless the Board of Directors determines
that such valuation does not constitute fair value. Futures and options thereon
which are traded on commodities exchanges will be valued at their closing
settlement price on such exchange. Securities and assets for which market
quotations are not readily available, and other assets, if any, will be valued
at fair value as determined in good faith and pursuant to procedures established
by the Board of Directors of the Fund.

         The outstanding shares of Common Stock are, and the Shares will be,
listed on the New York Stock Exchange Incorporated and the Pacific Exchange. The
Fund's Shares of Common Stock have traded in the market above, at and below net
asset value since the commencement of the Fund's operations in September 1988.
During the past seven years, the Fund's shares have generally traded in the
market at a premium above net asset value; however, the Fund's officers cannot
predict whether the Fund's Common Stock will trade in the future at a premium or
a discount to net asset value, and if so, the level of such premium or discount.


                                    TAXATION

         The following is a summary of the principal U.S. Federal income, and
certain state and local, tax considerations regarding the purchase, ownership
and disposition of shares of the Fund. The summary does not address special tax
rules applicable to certain classes of investors, such as tax-exempt entities,
insurance companies and financial institutions. Each prospective shareholder is
urged to consult his or her own tax adviser with respect to the specific
Federal, state, local and foreign tax consequences of investing in the Fund. The
summary is based on the laws in effect on the date of this SAI, which are
subject to change.

GENERAL

         The Fund has elected to be treated, has qualified and intends to
continue to qualify for each taxable year, as a regulated investment company
under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"). To so qualify, the Fund must comply with certain requirements of the
Code relating to, among other things, the source of its income and the
diversification of its assets.


                                       14
<PAGE>   57
         If the Fund complies with such requirements, then in any taxable year
for which the Fund distributes, in accordance with the Code's timing
requirements, ordinary income dividends of at least 90% of its investment
company taxable income, the Fund (but not its shareholders) will be relieved of
Federal income tax on any income of the Fund, including capital gains, that is
distributed to shareholders in accordance with the Code's requirements. However,
if the Fund retains any investment company taxable income or net capital gain,
it will be subject to a tax at regular corporate rates on the amount retained.

         In order to avoid a 4% Federal excise tax, the Fund must distribute (or
be deemed to have distributed) by December 31 of each calendar year at least 98%
of its taxable ordinary income for such year, at least 98% of the excess of its
capital gains over its capital losses, and all taxable ordinary income and the
excess of capital gains over capital losses for the previous year that were not
distributed for such year and on which the Fund did not pay Federal income tax.
The Fund intends to distribute at least annually to its shareholders all or
substantially all of its investment company taxable income and its net capital
gain, but reserves the right to retain and designate as described in the above
paragraph, its net capital gain.

         The Fund's investments, if any, in securities issued at a discount or
providing for deferred interest payments or payments of interest in kind will
generally cause the Fund to realize income prior to the receipt of cash payments
with respect to these securities. Mark to market rules applicable to certain
options and futures contracts may also require that net gains be recognized
without a concurrent receipt of cash. In order to obtain cash to distribute its
income or gains, maintain its qualification as a regulated investment company
and avoid Federal income or excise taxes, the Fund may be required to liquidate
portfolio securities that it might otherwise have continued to hold.

TAXABLE U.S. SHAREHOLDERS - DISTRIBUTIONS

         For U.S. Federal income tax purposes, distributions by the Fund,
whether reinvested in additional shares or paid in cash, generally will be
taxable to shareholders who are subject to tax.

         Distributions from the Fund's investment company taxable income will be
taxable as ordinary income, and generally cannot be offset by capital losses.
For corporate shareholders, distributions designated as derived from the Fund's
dividend income that would be eligible for the dividends received deduction if
the Fund were not a regulated investment company will be eligible, subject to
certain holding period and debt-financing restrictions, for the 70% dividends
received deduction. (However, the entire dividend, including the deducted
amount, is includable in determining a corporate shareholder's alternative
minimum taxable income.) So long as the Fund qualifies as a regulated investment
company and satisfies the 90% distribution requirement, capital gain dividends
if properly designated as such in a written notice to shareholders mailed not
later than 60 days after the Fund's taxable year closes, will be taxed to
shareholders as capital gain which, as to non-corporate shareholders, will be
taxable at maximum marginal Federal income tax rates of (i) 28% for the portion
of such dividends designated by the Fund as a 28% rate gain distribution, and
(ii) 20% for the portion of such dividends designated by the Fund as a 20% rate
gain distribution, respectively, regardless of how long the shareholder has held
his or her Fund shares. Distributions, if any, that are in excess of the Fund's
current and accumulated earnings and profits, as computed for Federal income tax
purposes, will first reduce a shareholder's tax basis in his or her shares and,
after such basis is reduced to zero, will constitute capital gains to a
shareholder who holds his or her shares as capital assets.


                                       15
<PAGE>   58
         All distributions, whether received in shares or in cash, as well as
sales and exchanges of Fund shares, must be reported by each shareholder who is
required to file a U.S. Federal income tax return. For Federal income tax
purposes, dividends declared by the Fund in October, November or December to
shareholders on a specified date in such a month and paid during January of the
following year are treated as if they were paid by the Fund and received by such
shareholders on December 31 of the year declared. In addition, certain other
distributions made after the close of a taxable year may be "spilled back" and
treated as paid by the Fund (other than for purposes of avoiding the 4% excise
tax) during such year. Such dividends would be taxable to the shareholders in
the taxable year in which the distribution was actually made by the Fund.

         The Fund will send written notices to shareholders regarding the amount
and Federal income tax status of all distributions made during each calendar
year.

         With respect to distributions paid in cash or, for shareholders
participating in the Distribution Reinvestment and Cash Purchase Plan (the
"Plan"), reinvested in shares purchased in the open market, the amount of the
distribution for tax purposes is the amount of cash distributed or allocated to
the shareholder. With respect to distributions issued in shares of the Fund, the
amount of the distribution for tax purposes is the fair market value of the
issued shares on the payment date.

Distributions by the Fund result in a reduction in the net asset value of the
Fund's shares and may also reduce their market value. Should a distribution
reduce the net asset value or market value below a shareholder's cost basis,
such distribution (to the extent paid from the Fund's current or accumulated
earnings and profits) would nevertheless be taxable to the shareholder as
ordinary income or capital gain as described above even though, from an
investment standpoint, it may constitute a partial return of capital. In
particular, investors should be careful to consider the tax implications of
buying shares just prior to a distribution. Since the market price of shares
purchased at that time may include the amount of any forthcoming distribution,
investors purchasing shares just prior to a distribution will in effect receive
a return of a portion of their investment in the form of a distribution which
nevertheless will be taxable to them.

TAXABLE U.S. SHAREHOLDERS - SALE OF SHARES

         When a shareholder's shares are sold, exchanged or otherwise disposed
of, the shareholder will generally recognize gain or loss equal to the
difference between the shareholder's adjusted tax basis in the shares and the
cash, or fair market value of any property, received. Assuming the shareholder
holds the shares as a capital asset at the time of such sale or other
disposition, such gain or loss should be capital gain or loss which will be
long-term if the shares were held for more than 18 months, mid-term if the
shares were held between 12 and 18 months, and short-term if the shares were
held for 12 months or less. For non-corporate shareholders, short-term gain is
taxable at a maximum marginal Federal income tax rate of 39.6%, whereas mid-term
and long-term capital gains qualify for lower maximum marginal Federal income
tax rates (i.e., 28% and 20%, respectively). However, it currently appears that
any loss realized on the sale, exchange or other disposition of Fund shares with
a tax holding period of six months or less will be treated as a long-term
capital loss to the extent of any capital gain dividend received by the selling
shareholder with respect to such shares, even if part or all of such dividend
was taxed at the 28% rate applicable to mid-term capital gains as discussed
under the preceding subheading. Additionally, any loss realized on a sale or
other disposition of shares of the Fund may be disallowed under "wash sale"
rules to the extent the shares disposed of are replaced with other shares of the
Fund within a period of 61 days beginning 30 days before and ending 30 days
after the shares are disposed of,


                                       16
<PAGE>   59
such as pursuant to a distribution reinvestment in shares of the Fund under the
Plan. If disallowed, the loss will be reflected in an adjustment to the basis of
the shares acquired.

BACKUP WITHHOLDING

         The Fund will be required to report to the Internal Revenue Service all
distributions, as well as gross proceeds from the sale or exchange of Fund
shares with respect to which the Fund is a payor (such as pursuant to a tender
offer), except in the case of certain exempt recipients, i.e., corporations and
certain other investors to which distributions are exempt from the information
reporting provisions of the Code. Under the backup withholding provisions of
Code Section 3406 and applicable Treasury regulations, all such reportable
distributions and proceeds may be subject to backup withholding of Federal
income tax at the rate of 31% in the case of nonexempt shareholders who fail to
furnish the Fund with their correct taxpayer identification number and with
certain required certifications or if the Internal Revenue Service or a broker
notifies the Fund that the number furnished by the shareholder is incorrect or
that the shareholder is subject to backup withholding as a result of failure to
report interest or dividend income. The Fund may refuse to accept any
subscription that does not contain any required taxpayer identification number
or certification that the number provided is correct. If the backup withholding
provisions are applicable, any such distributions and proceeds, whether taken in
cash or reinvested in shares, will be reduced by the amounts required to be
withheld. Any amounts withheld would be credited against a shareholder's U.S.
Federal income tax liability. Investors should consult their tax advisers about
the applicability of the backup withholding provisions.

NON-U.S. SHAREHOLDERS

         The foregoing discussion relates solely to U.S. Federal income tax law
as it applies to "U.S. persons" (i.e., U.S. citizens or residents and U.S.
domestic corporations, partnerships, trusts or estates) subject to tax under
such law. Dividends of investment company taxable income distributed by the Fund
to a shareholder who is not a U.S. person will be subject to U.S. withholding
tax at the rate of 30% (or a lower rate provided by an applicable tax treaty)
unless the dividends are effectively connected with a U.S. trade or business of
the shareholder, in which case the dividends will be subject to tax on a net
income basis at the graduated rates applicable to U.S. individuals or domestic
corporations and, in the case of a shareholder that is a foreign corporation,
may be subject to U.S. "branch profit tax." Capital gain distributions to a
non-U.S. shareholder will not be subject to U.S. income or withholding tax
unless the distributions are effectively connected with the shareholder's trade
or business in the U.S. or, in the case of a shareholder who is a nonresident
alien individual, the shareholder is present in the U.S. for 183 days or more
during the taxable year and certain other conditions are met.

         Any gain realized by a shareholder who is not a U.S. person upon a sale
or other disposition of shares of the Fund will not be subject to U.S. Federal
income or withholding tax unless the gain is effectively connected with the
shareholder's trade or business in the U.S., or in the case of a shareholder who
is a nonresident alien individual, the shareholder is present in the U.S. for
183 days or more during the taxable year and certain other conditions are met.
Non-U.S. persons who fail to furnish the Fund with an IRS Form W-8 or acceptable
substitute Form W-8 may be subject to backup withholding at the rate of 31% on
capital gain dividends and the proceeds of certain sales of their shares with
respect to which the Fund is a payor (such as pursuant to a tender offer).
Investors who are not U.S. persons should consult their tax advisers about the
U.S. and non-U.S. tax consequences of ownership of shares of, and receipt of
distributions from, the Fund.

STATE AND LOCAL TAXES

         The Fund may be subject to state or local taxes in jurisdictions in
which the Fund may be deemed to be doing business. In addition, in those states
or localities which have income tax laws, the treatment of the Fund and its
shareholders under such laws may differ from their treatment under Federal
income tax laws, and an investment in the Fund may have tax consequences for
shareholders different from those of a direct investment in the Fund's portfolio
securities. Shareholders should consult their own tax advisers concerning these
matters.


                             INDEPENDENT ACCOUNTANTS

         Coopers & Lybrand L.L.P., 1301 Avenue of the Americas, New York, New
York 10019, serves as the independent accountants for the Fund. In addition to
reporting annually on the financial statements of the Fund, the Fund's
accountants also review certain filings of the Fund with the Commission.


                             PRINCIPAL SHAREHOLDERS

         There are no persons known to the Fund to be control persons of the
Fund, as such term is defined in Section 2(a)(9) of the 1940 Act. There is no
person known to the Fund to hold beneficially more than 5% of the outstanding
shares of the Fund. The following person is the only person holding of record
more than 5% of the 79,017,765 outstanding shares of the Fund as of March 31,
1998:


                                            AMOUNT OF         PERCENT
         NAME AND ADDRESS OF                RECORD            OF

         7 Hanover Square
         New York, New York 10004

         As of March 31, 1998, the current Directors and Officers of the Fund,
as a group, beneficially owned less than 1% of the Fund's outstanding shares.

                        THE ZWEIG TOTAL RETURN FUND, INC.
                          NOTES TO FINANCIAL STATEMENTS
                                DECEMBER 31, 1997

NOTE 1--Significant Accounting Policies

     The Zweig Total Return Fund, Inc. (the "Fund") is a closed-end, diversified
management  investment  company  registered under the Investment  Company Act of
1940  (the  "Act").  The Fund was  incorporated  under  the laws of the State of
Maryland on July 21, 1988. The following is a summary of significant  accounting
policies  consistently  followed by the Fund in the preparation of its financial
statements. The preparation of financial statements in accordance with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts and  disclosures in the financial
statements. Actual results could differ from those estimates.

   A. Portfolio Valuation

     Portfolio securities which are traded only on stock exchanges are valued at
the last sale price.  Securities traded in the over-the-counter market which are
National  Market  System  securities  are valued at the last sale  price.  Other
over-the-counter  securities  are valued at the most  recently  quoted bid price
provided by the principal market makers.  Portfolio  securities which are traded
both in the over-the-counter market and on a stock exchange are valued according
to the broadest and most representative  market, as determined by the Investment
Adviser.  Debt  securities  may be valued on the basis of prices  provided by an
independent  pricing  service  when such prices are  believed by the  Investment
Adviser  to  reflect  the  fair  market  value  of such  securities.  Short-term
investments  having a remaining  maturity of 60 days or less when  purchased are
valued at amortized cost (which  approximates  market value).  Futures which are
traded on commodities  exchanges are valued at their closing settlement price on
such exchange.  Securities for which market quotations are not readily available
(of which there were none at December  31, 1997) and other  assets,  if any, are
valued at fair value as  determined  under  procedures  approved by the Board of
Directors of the Fund.

   B. Security Transactions and Investment Income

     Security  transactions  are  recorded  on trade  date.  Dividend  income is
recorded on the  ex-dividend  date.  Interest  income is recorded on the accrual
basis.

     Realized  gains and losses on sales of  investments  are  determined on the
identified cost basis for financial reporting and tax purposes.

   C. Futures Contracts

     Initial  margin  deposits  made upon  entering  into futures  contracts are
recorded as assets.  During the period the futures contract is open,  changes in
the  value of the  contract  are  recognized  as  unrealized  gains or losses by
marking the  contract to market on a daily basis to reflect the market  value of
the contract at the end of each day's  trading.  Variation  margin  payments are
made or received and recognized as assets or liabilities, depending upon whether
unrealized gains or losses are incurred.  When the contract is closed,  the Fund
records a realized  gain or loss equal to the  difference  between the  proceeds
from (or cost of) the closing  transaction and the Fund's basis in the contract.
There are several  risks in  connection  with the use of futures  contracts as a
hedging device. The change in value of futures contracts  primarily  corresponds
with the value of their underlying instruments, which may not correlate with the
change in value of the hedged investments.  Therefore, anticipated gains may not
result and anticipated  losses may not be offset.  In addition,  as no secondary

   D. Short Sales

     A short sale is a  transaction  in which the Fund sells a security  it does
not own in  anticipation of a decline in market price. To sell a security short,
the Fund must borrow the security. The Fund's obligation to replace the security
borrowed  and  sold  short  will be  fully  collateralized  at all  times by the
proceeds from the short sale  retained by the broker and by cash and  securities
deposited in a segregated account with the Fund's custodian.  In addition to the
short sales described  above, the Fund may make short sales "against the box". A
short sale  "against  the box" is a short sale  whereby at the time of the short
sale, the Fund owns or has the immediate and  unconditional  right,  at no added
cost, to obtain the identical security.  If the price of the security sold short
increases  between the time of the short sale and the time the Fund replaces the
borrowed security,  the Fund will incur a loss, and if the price declines during
the period,  the Fund will realize a gain.  Any realized gain will be decreased,
and any incurred loss increased,  by the amount of transaction costs.  Dividends
or interest  the Fund pays in  connection  with such short sales are recorded as
expenses.

   E. Federal Income Tax

     The Fund has  elected  to qualify  and  intends  to remain  qualified  as a
"regulated  investment  company" under Subchapter M of the Internal Revenue Code
of 1986,  as amended.  The  principal  tax benefits of qualifying as a regulated
investment  company as compared to an ordinary taxable  corporation,  are that a
regulated  investment  company  is not itself  subject to Federal  income tax on
ordinary investment income and net capital gains that are currently  distributed
(or  deemed  distributed)  to its  shareholders  and that the tax  character  of
long-term  capital  gains  recognized  by a regulated  investment  company flows
through to its shareholders who receive distributions of such gains.

   F. Dividends and Distributions to Shareholders

     Dividends and distributions to shareholders are recorded on the ex-dividend
date. In the event that amounts  distributed  are in excess of  accumulated  net
investment  income and net realized  gains on  investments  (as  determined  for
financial statement purposes),  such amounts would be reported as a distribution
from  paid-in  capital  during the fiscal year in which such a  distribution  is
made.  Income  dividends  and  capital  gain  distributions  are  determined  in
accordance with income tax regulations which may differ from generally  accepted
accounting principles. These differences are primarily due to timing differences
and differing  characterization  of  distributions  made by the Fund as a whole.
During the year ended  December 31,  1997,  the Fund  reclassified  $84,900 from
undistributed   net  realized   gains  to  capital   paid-in  and  $20,037  from
undistributed net investment income to undistributed net realized gains.

NOTE 2--Portfolio Transactions

sale transactions, excluding short term instruments and futures transactions, as

preparation of financial  information  for the Fund's income tax returns,  proxy

interested persons of the Fund or the Investment Adviser receive no remuneration
from the Fund.

     d) Legal  Fees:  The Fund  incurred  legal fees of $16,161  during the year
ended  December  31,  1997,  for the  services of Rosenman & Colin LLP, of which
Robert E. Smith, a Director of the Fund, is a partner.

     e) Brokerage Commissions: During the year ended December 31, 1997, the Fund
paid Zweig Securities Corp. brokerage  commissions of $80,824 in connection with
portfolio  transactions  effected  through them. In addition,  Zweig  Securities
Corp.  charged $6,529 in commissions for transactions  effected on behalf of the
participants in the Fund's Automatic Reinvestment and Cash Purchase Plan.

     Certain  directors  and  officers  of the Fund are  also  directors  and/or

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Shareholders and Board of Directors of
     The Zweig Fund, Inc.

     We have audited the accompanying statement of assets and liabilities of The
Zweig Total Return Fund,  Inc.,  including  the schedule of  investments,  as of
December 31, 1997,  and the related  statement  of  operations  for the year
then ended,  the statement  of changes in net assets for each of the two years
in the period then ended,  and the  financial  highlights  for each of the five
years in the period then  ended.  These  financial  statements  and  financial
highlights  are  the responsibility  of the management of the Fund. Our
responsibility is to express an opinion on these financial  statements and
financial  highlights based on our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
December 31, 1997, 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  financial  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 The
Zweig Total Return Fund,  Inc. as of December 31, 1997, 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 five years in the  period  then  ended,  in  conformity  with  generally
accepted  accounting principles.
