Notes to Financial Statements

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

(a) Organization - Bancroft Fund Ltd. (the “Fund”), is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company.

(b) Indemnification - Under the Fund’s organizational documents, each trustee, officer or other agent of the Fund (including the Fund’s investment adviser) is indemnified against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. The risk of material loss as a result of such indemnification is considered remote.

(c) Security Valuation - Investments in securities traded on a national securities exchange are valued at market using the last reported sales price, supplied by an independent pricing service, 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 the independent pricing service, or, if an evaluated quote is unavailable, such securities are valued using prices received from dealers, provided that if the dealer supplies both bid and asked prices, the price to be used is the mean of the bid and asked prices. 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 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.

The Fund has adopted authoritative fair valuation accounting standards which establish an authoritative definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs and valuation techniques used to develop the measurements of fair value and a discussion of changes in valuation techniques and related inputs during the period. These inputs are summarized in the three broad levels listed below:

Level 1 - Quoted unadjusted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-driven valuation in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or instances where prices vary substantially over time or among brokered market makers, and those received from an independent pricing service.

Level 3 - Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect the Fund’s own assumptions that market participants would use to price an asset or liability based on the best available information.

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of the markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

The net change in unrealized depreciation from Level 3 investments held as of October 31, 2015 was ($29,969) and is included in the net change in unrealized appreciation of investments in the Statement of Operations. Transfers into, or out of, Level 3 are valued utilizing values as of the end of the period. Transfers into Level 3 were due to a decline in market activity (e.g., frequency of trades), which resulted in a lack of available market inputs to determine price.

Refer to the Fund’s Portfolio of Investments for a detailed breakdown of Common Stock, Convertible Bonds and Notes, Convertible Preferred Stock and Mandatory Convertible Securities. Transfers between levels are recognized at October 31, 2015, the end of the reporting period. The Fund recognized no transfers to or from Level 1 to Level 2.

The following is a reconciliation of assets for which Level 3 inputs were used in determining value:

(1) Included in the net change in unrealized appreciation of investments in the Statement of Operations.

(1) In determining certain of these inputs, management evaluates a variety of factors including economic conditions, industry and market developments, market valuations of comparable companies and company specific developments.

(2) This column represents the directional change in the fair value of the Level 3 investments that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the opposite effect.

(d) Federal Income Taxes - The Fund’s policy is to distribute substantially all of its taxable income within the prescribed time and to otherwise comply with the provisions of the Internal Revenue Code applicable to regulated investment companies. Therefore, no provision for federal income or excise taxes is believed necessary.

The Fund recognizes the tax benefits of uncertain tax positions only where the position is “more-likely-than-not” to be sustained assuming examination by taxing authorities. Management of the Fund has analyzed the Fund’s tax positions, and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on returns filed for open tax years (2012-2014), or expected to be taken in the Fund’s 2015 tax returns. The major tax authority for the Fund is the Internal Revenue Service. The Fund is not aware of any tax positions for which it is reasonably likely that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

(e) Securities Transactions and Related Investment Income - Securities transactions are accounted for on the trade date (the 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. Contingent interest income amounted to $10,796 for the twelve months ended October 31, 2015.

(f) Distributions to Shareholders - Distributions to shareholders from net investment income are recorded by the Fund on the ex-dividend date. Distributions from capital gains, if any, are recorded on the ex-dividend date and paid annually.

The amount and character of income and capital gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. The tax character of distributions paid during the fiscal years ended October 31, 2015 and 2014 were as follows:

At October 31, 2015, the components of distributable earnings and federal tax cost were as follows:

Notes to Financial Statements (continued)

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (continued)

The differences between book-basis and tax-basis unrealized appreciation/depreciation is attributable to differing methods of recognizing interest and ordinary income on bonds for tax purposes.

To the extent the Fund’s net realized capital gains, if any, can be offset by capital loss carryforwards, it is the policy of the Fund not to distribute such gains. As determined at October 31, 2015, the Fund utilized $176,556 of its capital loss carryforwards.

(g) Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

(h) Regulated Investment Company Modernization Act - On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the Modernization Act) was signed into law. The Modernization Act modernizes several of the federal income and excise tax provisions related to regulated investment companies (“RICs”).

New capital losses may now be carried forward indefinitely and retain the character of the original loss. Under pre-enactment law, capital losses could be carried forward for eight years, and carried forward as short-term capital losses, irrespective of the character of the original loss. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

(i) Market Risk - It is the Fund’s policy to invest at least 65% of its assets in convertible securities. Although convertible securities do derive part of their value from that of the securities into which they are convertible, they are not considered derivative financial instruments. However, the Fund’s mandatory convertible securities include features which render them more sensitive to price changes of their underlying securities. Thus they expose the Fund to greater downside risk than traditional convertible securities, but generally less than that of the underlying common stock. The market value of those securities was $19,773,897 at October 31, 2015, representing approximately 16.7% of net assets.

(j) Reclassification of Capital Accounts - Accounting principles generally accepted in the United States require that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. At October 31, 2015 the Fund decreased undistributed net investment loss by $73,878 and decreased accumulated net realized gain on investments by $73,878.

NOTE 2 - MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

The Fund has entered into an investment advisory agreement with Dinsmore Capital Management Co. (“Dinsmore Capital”). Pursuant to the investment advisory agreement, Dinsmore Capital provides the Fund with investment advice, office space and facilities. Under the terms of the investment advisory agreement, the Fund pays Dinsmore Capital on the last day of each month an advisory fee for such month computed at an annual rate of 0.75% of the first $100,000,000 and 0.50% of the excess over $100,000,000 of the Fund’s net asset value in such month.

The Fund, pursuant to an administrative services agreement with Dinsmore Capital, has agreed to pay Dinsmore Capital for certain accounting and other administrative services provided to the Fund. Under the administrative services agreement, the Fund pays Dinsmore Capital on the last day of each month a fee for such month computed at an annual rate of 0.05% of the Fund’s net asset value in such month.

Certain officers and trustees of the Fund are officers and directors of Dinsmore Capital.

On October 19, 2015 shareholders of the Fund (1) approved a new investment advisory agreement with Gabelli Funds, LLC and (2) elected new trustees. The new investment advisory agreement was effective on November 1, 2015, and the Fund is now managed by the Dinsmore Group of Gabelli Funds, LLC.

Gabelli Funds, LLC was also retained as the Fund’s administrator under the agreement.

During the year ended October 31, 2014, the Fund repurchased 154,943 capital shares in the open market at a cost of $2,968,847. The weighted average discount of these purchases comparing the average purchase price to net asset value was 16.32%.

Purchases and sales of investments, exclusive of corporate short-term notes, aggregated $57,629,893 and $64,240,566, respectively, for the twelve months ended October 31, 2015.

NOTE 4 - NEW ACCOUNTING PRONOUNCEMENT

In May 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-07 “Disclosure for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent).” The amendments in ASU No. 2015-07 remove the requirement to categorize within the fair value hierarchy investments measured using the NAV practical expedient. The ASU also removes certain disclosure requirements for investments that qualify, but do not utilize, the NAV practical expedient. The amendments in the ASU are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Management is currently evaluating the impact these changes will have on the Fund’s financial statements and related disclosures.

NOTE 5 - SUBSEQUENT EVENTS

In preparing the financial statements as of October 31, 2015, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements.

Effective November 1, 2015, the Fund has entered into an investment advisory agreement (the “Advisory Agreement”) with Gabelli Funds, LLC (the “Adviser”) which provides that the Fund will pay the Adviser a fee, computed daily and paid monthly, equal on an annual basis to 0.80% of the first $100,000,000 of the Fund’s average weekly net assets and 0.55% of the Fund’s average weekly net assets in excess of $100,000,000. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund’s portfolio and oversees the administration of all aspects of the Fund’s business and affairs.

Report of Independent Registered

Public Accounting Firm

To the Shareholders and Board of Trustees of Bancroft Fund Ltd.

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments of Bancroft Fund Ltd. (the “Fund”) as of October 31, 2015, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2015, by correspondence with the custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Bancroft Fund Ltd. as of October 31, 2015, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Automatic Dividend Investment and Cash Payment Plan

The Fund has an Automatic Dividend Investment and Cash Payment Plan (the “Plan”). Any shareholder may elect to join the Plan by sending an application to American Stock Transfer & Trust Company, P.O. Box 922, Wall Street Station, New York, NY 10269-0560 (the “Plan Agent”). You may also obtain information about the Plan, as well as the Plan application, by calling the Plan Agent toll free at (877) 208-9514. If your shares are held by a broker or other nominee, you should instruct the nominee to join the Plan on your behalf. Some brokers may require that your shares be taken out of the broker’s “street name” and re-registered in your own name. Shareholders should also contact their broker to determine whether shares acquired through participation in the Plan can be transferred to another broker and thereafter, whether the shareholder can continue to participate in the Plan.

Under the Plan, all dividends and distributions are automatically invested in additional Fund shares. Depending on the circumstances, shares may either be issued by the Fund or acquired through open market purchases at the current market price or net asset value, whichever is lower (but not less than 95% of market price). For shareholder distributions made with respect to income earned during each of the first three fiscal quarters, when the market price of a share of Fund beneficial shares is lower than such share’s net asset value, the Plan Agent will combine the distributions of all Plan participants and purchase shares in the open market, thereby taking advantage of the lower commissions on larger purchases. There is no other charge for this service. For shareholder distributions made with respect to capital gains realized during the fiscal year and income earned during the fourth fiscal quarter, when the market price of a share of Fund shares is lower than such share’s net asset value, the Fund will issue shares at the market price.

All dividends and distributions made by the Fund (including capital gain dividends and dividends designated as qualified dividend income, which are eligible for taxation at lower rates) remain taxable to Plan participants, regardless of whether such dividends and distributions are reinvested in additional shares of the Fund through open market purchases or through the issuance of new shares. Plan participants will be treated as receiving the cash used to purchase shares on the open market and, in the case of any dividend or distribution made in the form of newly issued shares, will be treated as receiving an amount equal to the fair market value of such shares as of the reinvestment date. Accordingly, a shareholder may incur a tax liability even though such shareholder has not received a cash distribution with which to pay the tax.

Plan participants may also voluntarily send cash payments of $100 to $10,000 per month to the Plan Agent, to be combined with other Plan monies, for purchase of additional Fund shares in the open market. You pay only a bank service charge of $1.25 per transaction, plus your proportionate share of the brokerage commission. All shares and fractional shares purchased will be held by the Plan Agent in your dividend reinvestment account. You may deposit with the Plan Agent any Fund share certificates you hold, for a one-time fee of $7.50.

At any time, a Plan participant may instruct the Plan Agent to liquidate all or any portion of such Plan participant’s account. To do so, a Plan participant must deliver written notice to the Plan Agent prior to the record date of any dividend or distribution requesting either liquidation or a share certificate. The Plan Agent will combine all liquidation requests it receives from Plan participants on a particular day and will then sell shares of the Fund that are subject to liquidation requests in the open market. The amount of proceeds a Plan participant will receive shall be determined by the average sales price per share, after deducting brokerage commissions, of all shares sold by the Plan Agent for all Plan participants who have given the Plan Agent liquidation requests.

The Plan Agent or the Fund may terminate the Plan for any reason at any time by sending written notice addressed to the Plan participant’s address as shown on the Plan Agent’s records. Following the date of termination, the Plan Agent shall send the Plan participant either the proceeds of liquidation, or a share certificate or certificates for the full shares held by the Plan Agent in the Plan participant’s account. Additionally, a check will be sent for the value of any fractional interest in the Plan participant’s account based on the market price of the Fund’s shares on that date.
