Glossary

American Depositary Receipt (ADR): Represents shares of foreign companies
traded in U.S. dollars on U.S. exchanges that are held by a bank or a trust.
Foreign companies use ADRs in order to make it easier for Americans to buy
their shares.

Basis Point (bp): One-hundredth of a percentage point (0.01%). Basis points are
often used to measure changes in or differences between yields on fixed income
securities, since these often change by very small amounts.

Consumer Price Index (CPI): Measures the change in consumer prices of goods and
services, including housing, electricity, food, and transportation, as
determined by a monthly survey of the U.S. Bureau of Labor Statistics. Also
called the cost-of-living index.

Dow Jones Industrial Average/SM/ (the "Dow"): A price-weighted average of 30
blue chip stocks. The index is calculated on a total return basis with
dividends reinvested.

Federal funds rate: The interest rate charged on overnight loans of reserves by
one financial institution to another in the United States. The federal funds
rate is the most sensitive indicator of the direction of interest rates since
it is set daily by the market.

Federal Reserve (the "Fed"): The central bank of the United States, responsible
for controlling the money supply, interest rates and credit with the goal of
keeping the U.S. economy and currency stable. Governed by a seven-member board,
the system includes 12 regional Federal Reserve Banks, 25 branches and all
national and state banks that are part of the system.

Gross domestic product (GDP): An important measure of the United States'
economic performance, GDP is the total market value of all final goods and
services produced in the U.S. during any quarter or year.

Inflation: Rise in the prices of goods and services resulting from increased
spending relative to the supply of goods on the market.

Initial public offering (IPO): A company's first sale of stock to the public.

NASDAQ Composite(R) Index: A market capitalization-weighted index of all issues
listed in the NASDAQ (National Association Of Securities Dealers Automated
Quotation System) Stock Market, except for closed-end funds, convertible
debentures, exchange traded funds, preferred stocks, rights, warrants, units
and other derivative securities. The index is calculated on a total return
basis with dividends reinvested.

Reuters CRB (Commodity Research Bureau) Index: Tracks 17 component commodities
ranging from key economic indicators like gold and oil to other important
commodities such as cocoa, coffee and orange juice.

Reuters Estimates: Provides major institutional sell-side and buy-side firms,
financial data providers and corporations around the world with research and
analysis on over 14,500 active companies and 10,000 inactive companies in more
than 70 countries.

                                        1



S&P 500(R) Index: A market capitalization-weighted index of 500 of the largest
U.S. companies. The index is calculated on a total return basis with dividends
reinvested.

Short Interest: The total number of shares of a security that have been sold
short by customers and securities firms that have not been repurchased to
settle short positions in the market.





Indexes cited are unmanaged and not available for direct investment; therefore
their performance does not reflect the expenses associated with the active
management of an actual portfolio.

THE ZWEIG FUND, INC.
NOTES TO ITS SCHEDULE OF INVESTMENTS AND SECURITIES SOLD SHORT (Unaudited)
MARCH 31, 2005

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of significant accounting policies consistently
followed by the Zweig Fund in the preparation of its Schedule of Investments and
Securities Sold Short. The preparation of its 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 its 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 other assets, if any, 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.

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. The gain or loss resulting from a change in currency exchange rates
between the trade and settlement dates of a portfolio transaction is treated as
a gain or loss on foreign currency. Likewise, the gain or loss resulting from a
change in currency exchange rates between the date income is accrued and paid is
treated as a gain or loss on foreign currency. The Fund does not isolate that
portion of the results of operations arising from changes in exchange rates and
that portion arising from changes in the market prices of securities.



THE ZWEIG FUND, INC.
NOTES TO ITS SCHEDULE OF INVESTMENTS AND SECURITIES SOLD SHORT (Unaudited)
MARCH 31, 2005

D. Forward Currency Contracts:

     The Fund may enter into forward currency contracts in conjunction with the
planned purchase or sale of foreign denominated securities in order to hedge the
U.S. dollar cost or proceeds. Forward currency contracts involve, to varying
degrees, elements of market risk in excess of the amount recognized in the
Statement of Assets and Liabilities. Risks arise from the possible movements in
foreign exchange rates or if the counterparty does not perform under the
contract.

     A forward currency contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any number of days from the
date of the contract agreed upon by the parties, at a price set at the time of
the contract. These contracts are traded directly between currency traders and
their customers. The contract is marked-to-market daily and the change in market
value is recorded by the Fund as an unrealized gain or loss. When the contract
is closed or offset with the same counterparty, the Fund records a realized gain
or loss equal to the change in the value of the contract when it was opened and
the value at the time it was closed or offset.

E. 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 greatest percentage of company revenue is
generated.

F. 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. Gains and losses on written
options are reported separately in the Statement of Operations. 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. As of March
31, 2005, the Fund has one option outstanding.

G. 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 by, and any realized loss increased by, the amount of
transaction costs. Dividends on short sales are recorded as an expense to the
Fund on ex-dividend date. At March 31, 2005 the value of securities sold short
amounted to $15,631,050 against which collateral of $37,023,700 was held. The
collateral includes the deposits with 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.

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

MARCH 31, 2005

of these investments and the income they generate, as well as a fund's ability
to repatriate such amounts.

     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 the Fund, positive or
negative, than if the Fund did not concentrate its investments in such sectors.



Item 2. Controls and Procedures.

          or persons performing similar functions, have concluded that the

     (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
