                             THE ZWEIG FUND, INC.

                       NOTES TO SCHEDULE OF INVESTMENTS

                                MARCH 31, 2010
                                  (UNAUDITED)

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

   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 conformity with accounting principals
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 financial statements and the reported amount of increases and decreases in
net assets from operations during the reporting period. Actual results could
differ from those estimates and those differences could be significant.

  A. SECURITY VALUATION:

   The Fund utilizes a fair value hierarchy which prioritizes the inputs to
valuation techniques used to measure fair value into three broad levels.

   .   Level 1 -- quoted prices in active markets for identical securities

   .   Level 2 -- prices determined using other significant observable inputs
       (including quoted prices for similar securities, interest rates,
       prepayment speeds, credit risk, etc.)

   .   Level 3 -- prices determined using significant unobservable inputs
       (including the Fund's own assumptions in determining the fair value of
       investments)

   A description of the valuation techniques applied to the Funds major
categories of assets and liabilities measured at fair value on a recurring
basis is as follows:

   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 and are categorized as Level
1 in the hierarchy. Restricted equity securities and private placements that
are not widely traded, are illiquid or are internally fair valued by the
advisor, are generally categorized as Level 3 in the hierarchy.

   Certain foreign securities 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 such cases the Fund fair values foreign securities using an
external pricing service which considers the correlation of the trading
patterns of the foreign security to the intraday trading in the U.S. markets
for investments such as American depositary receipts, financial futures,
exchange-traded funds, and certain indexes as well as prices for similar
securities. Such fair valuations are categorized as Level 2 in the hierarchy.
Because the frequency of significant events is not predictable, fair valuation
of certain foreign common stocks may occur on a frequent basis.

                                      5





   Debt securities, including restricted securities, are valued based on
evaluated quotations received from independent pricing services or from dealers
who make markets in such securities. For most bond types, the pricing service
utilizes matrix pricing which considers yield or price of bonds of comparable
quality, coupon, maturity, current cash flows, type, and current day trade
information, as well as dealer supplied prices. These valuations are generally
categorized as Level 2 in the hierarchy. Structured debt instruments also
incorporate collateral analysis and utilize cash flow models for valuation and
are generally categorized as Level 2 in the hierarchy. Pricing services do not
provide pricing for all securities and therefore dealer supplied prices are
utilized representing indicative bids based on pricing models used by market
makers in the security and are generally categorized as Level 2 in the
hierarchy. Debt securities that are not widely traded, are illiquid, or are
internally fair valued by the advisor are generally categorized as Level 3 in
the hierarchy.

   Listed derivatives that are actively traded are valued based on quoted
prices from the exchange and are categorized as Level 1 in the hierarchy. Over
the counter (OTC) derivative contracts, which include forward currency
contracts and equity linked instruments, do not require material subjectivity
as pricing inputs are observed from actively quoted markets and are categorized
as Level 2 in the hierarchy.

   Investments in open-end mutual funds are valued at their closing net asset
value determined as of the close of business of the New York Stock Exchange
(generally 4:00 p.m. Eastern time) each business day and are categorized as
Level 1 in the hierarchy.

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

   A summary of the inputs used to value the Funds' net assets by each major
security type is disclosed at the end of the Schedule of Investments for each
Fund. The inputs or methodology used for valuing securities are not necessarily
an indication of the risk associated with investing in those securities.

  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.
