NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

   The following is a summary of significant accounting policies consistently
followed by the Zweig Fund, Inc. (the "Fund") in the preparation of the
Schedule of Investments and Securities Sold Short. The preparation of the
Schedule of Investments and Securities Sold Short in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities, and contingent assets and liabilities at the date of
the Schedules of Investments. Actual results could differ from those estimates.

  A. Security Valuation:

   Equity securities are valued at the official closing price (typically last
sale) on the exchange on which the securities are primarily traded, or if no
closing price is available, at the last bid price.

   Debt securities are valued on the basis of broker quotations or valuations
provided by a pricing service, which in determining value utilizes information
with respect to recent sales, market transactions in comparable securities,
quotations from dealers, and various relationships between securities in
determining value.

   As required, some securities and assets may be valued at fair value as
determined in good faith by or under the direction of the Trustees.

   Certain foreign common stocks may be fair valued in cases where closing
prices are not readily available or are deemed not reflective of readily
available market prices. For example, significant events (such as movement in
the U.S. securities market, or other regional and local developments) may occur
between the time that foreign markets close (where the security is principally
traded) and the time that the Fund calculates its net asset value (generally,
the close of the NYSE) that may impact the value of securities traded in these
foreign markets. In these cases, information from an external vendor may be
utilized to adjust closing market prices of certain foreign common stocks to
reflect their fair value. Because the frequency of significant events is not
predictable, fair valuation of certain foreign common stocks may occur on a
frequent basis.

   Short-term investments having a remaining maturity of 60 days or less are
valued at amortized cost, which approximates market.

  B. Security Transactions and Related Income:

   Security transactions are recorded on the trade date. Dividend income is
recorded on the ex-dividend date, or in the case of certain foreign securities,
as soon as the Fund is notified. Interest income is recorded on the accrual
basis. The Fund amortizes premiums and accretes discounts using the effective
interest method. Realized gains and losses are determined on the identified
cost basis.

                                      7





  C. Foreign Currency Translation:

   Foreign securities and other assets and liabilities are valued using the
foreign currency exchange rate effective at the end of the reporting period.
Cost of investments is translated at the currency exchange rate effective at
the trade date.

  D. Foreign Security Country Determination:

   A combination of the following criteria is used to assign the countries of
risk listed in the schedule of investments and securities sold short: country
of incorporation, actual building address, primary exchange on which the
security is traded and country in which the greatest percentage of company
revenue is generated.

  E. Options:

   The Fund may write covered options or purchase options contracts for the
purpose of hedging against changes in the market value of the underlying
securities or foreign currencies. The Fund will realize a gain or loss upon the
expiration or closing of the option transaction. When a written option is
exercised, the proceeds on sales or amounts paid are adjusted by the amount of
premium received.

   The Fund may purchase options, which are included in the Fund's Schedule of
Investments and Securities Sold Short and subsequently marked-to-market to
reflect the current value of the option. When a purchased option is exercised,
the cost of the security is adjusted by the amount of premium paid. The risk
associated with purchased options is limited to the premium paid.

   Transactions in written options for the period ended September 30, 2005 were
as follows:



                                                       Number of  Premiums
                                                       Contracts  Received

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


  F. 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. 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 realize a loss, and
if the price declines during the period, the Fund will realize a gain. Any
realized gain will be decreased, and any realized loss increased, by the amount
of transaction costs. On ex-dividend date, dividends on short sales are
recorded as an expense to the Fund. At September 30, 2005, the value of
securities sold short amounted to $22,201,200 against which collateral of
$46,585,750 was held. The collateral includes the deposits with broker for
securities held short and the value of the segregated investments held long,

                                      8




as shown in the Schedule of Investments and Securities Sold Short. Short
selling used in the management of the Fund may accelerate the velocity of
potential losses if the prices of securities sold short appreciate quickly.
Stocks purchased may decline in value at the same time stocks sold short may
appreciate in value, thereby increasing potential losses.

NOTE 2 -- CREDIT RISK AND ASSET CONCENTRATION

   In countries with limited or developing markets, investments may present
greater risks than in more developed markets and the prices of such investments
may be volatile. The consequences of political, social or economic changes in
these markets may have disruptive effects on the market prices of these
investments and the income they generate, as well as the Fund's ability to
repatriate such amounts.

   The Fund may invest a high percentage of their assets in specific sectors of
the market in their pursuit of a greater investment return. Fluctuations in
these sectors of concentration may have a greater impact on the Fund, positive
or negative, than if the Fund did not concentrate its investments in such
sectors.

     (b)  There were no changes in the registrant's internal control over
          financial reporting (as defined in Rule 30a-3(d) under the 1940 Act
          (17 CFR 270.30a-3(d)) that occurred during the registrant's last
