(Selected) Notes to Financial Statements (unaudited)----------------------------

Bancroft Fund Ltd. (established in 1971)) (the "Fund"), is registered under the
Investment Company Act of 1940 as a diversified, closed-end management
investment company.

Note 1. Security Valuation - Investments in securities traded on a national
securities exchange are valued at market using the last reported sales price as
of the close of regular trading.  Listed securities, for which no sales were
reported, are valued at the mean between closing reported bid and asked prices
as of the close of regular trading.  Unlisted securities traded in the over-
the-counter market are valued using an evaluated quote provided by an
independent pricing service. The independent pricing service derives an
evaluated quote by obtaining dealer quotes, analyzing the listed markets,
reviewing trade execution data and employing sensitivity analysis. Evaluated
quotes may also reflect appropriate factors such as individual characteristics
of the issue, communications with broker-dealers, and other market data.
Securities for which quotations are not readily available, restricted
securities and other assets are valued at fair value as determined in good
faith by management pursuant to procedures approved by the Board of Trustees.
Short-term debt securities with original maturities of 60 days or less are
valued at amortized cost.

Note 2. Securities Transactions and Related Investment Income - Security
transactions are accounted for on the trade date (date the order to buy or sell
is executed) with gain or loss on the sale of securities being determined based
upon identified cost.  Dividend income is recorded on the ex-dividend date and
interest income is recorded on the accrual basis, including accretion of
discounts and amortization of non-equity premium. For certain securities, known
as "contingent payment debt instruments," Federal tax regulations require the
Fund to record non-cash "contingent" interest income in addition to interest
income actually received.

At January 31, 2007 unrealized appreciation (depreciation) of investment
securities on a tax basis were as follows:

Unrealized appreciation               $ 12,007,808
Unrealized depreciation                 (3,502,912)
                                      ------------
Net unrealized appreciation              8,504,896

Cost for federal income tax purposes  $120,442,849
