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 disclosure of contingent assets and liabilities
at the date of the Schedule of Investments and Securities Sold Short. 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 Directors.

   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.

                                      6





  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. 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 March 31, 2006, the value of securities
sold short amounted to $19,870,600 against which collateral of $42,810,205 was
held. The collateral includes the deposits with the broker for securities held
short and the value of the segregated investments held long, 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.

  F. Security Lending

   The Fund loans securities to qualified brokers through an agreement with
State Street Bank (the "Custodian") and the Fund. Under the terms of the
agreement, the Fund receives collateral with a market value not less than 100%
of the market value of loaned securities. Collateral is adjusted daily in
connection with changes in the market value of securities on loan. Collateral
consists of cash, securities issued or guaranteed by the U.S. Government or its
agencies and the sovereign debt of foreign countries. Cash collateral has been
invested in short-term money market funds. Dividends earned on the collateral
and premiums paid by the borrower are recorded as income by the Fund net of
fees and rebates charged by the Custodian for its services in connection with
this securities lending program. Lending portfolio securities involves a risk
of delay in the recovery of the loaned securities or in the foreclosure on
collateral.

NOTE 2 -- CREDIT RISK AND ASSET CONCENTRATIONS

   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 a Fund's ability to
repatriate such amounts.

                                      7





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