See accompanying notes to financial statements.

NOTE A. ORGANIZATION

Cornerstone Total Return Fund, Inc. (the “Fund”) was incorporated in New York on March 16, 1973 and commenced investment operations on May 15, 1973. Its investment objective is to seek capital appreciation with current income as a secondary objective. The Fund is registered under the Investment Company Act of 1940, as amended, as a closed-end, diversified management investment company. As an investment company, the Fund follows the accounting and reporting guidance of the Financial Accounting Standards Board Accounting Standards Codification Topic 946 “Financial Services – Investment Companies”.

NOTE B. SIGNIFICANT ACCOUNTING POLICIES

Management Estimates: The Fund is an investment company that applies the accounting and reporting guidance issued in Topic 946 by the U.S. Financial Accounting Standards Board. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make certain estimates and assumptions that may affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

Subsequent Events: The Fund has evaluated the need for additional disclosures and/or adjustments resulting from subsequent events through the date its financial statements were issued. Based on this evaluation, no additional disclosures or adjustments were required to such financial statements.

Portfolio Valuation: Investments are stated at value in the accompanying financial statements. Readily marketable portfolio securities listed on the New York Stock Exchange (“NYSE”) are valued, except as indicated below, at the last sale price reflected on the consolidated tape at the close of the NYSE on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices on such day. If no bid or asked prices are quoted on such day or if market prices may be unreliable because of events occurring after the close of trading, then the security is valued by such method as the Board of Directors shall determine in good faith to reflect its fair market value. Readily marketable securities not listed on the NYSE but listed on other domestic or foreign securities exchanges are valued in a like manner. Portfolio securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined as reflected on the consolidated tape at the close of the exchange representing the principal market for such securities. Securities trading on the Nasdaq Stock Market, Inc. (“NASDAQ”) are valued at the NASDAQ Official Closing Price.

Readily marketable securities traded in the over-the counter market, including listed securities whose primary market is believed by Cornerstone Advisors, Inc. (the “Investment Manager” or “Cornerstone”) to be over-the-counter, are valued at the mean of the current bid and asked prices as reported by the NASDAQ or, in the case of securities not reported by the NASDAQ or a comparable source, as the Board of Directors deem appropriate to reflect their fair market value. Where securities are traded on more than one exchange and also over-the-counter, the securities will generally be valued using the quotations the Board of Directors believes reflect most closely the value of such securities. At June 30, 2016 the Fund held no securities valued in good faith by the Board of Directors.

The net asset value per share of the Fund is calculated weekly and on the last business day of the month with the exception of those days on which the NYSE is closed.

The Fund is exposed to financial market risks, including the valuations of its investment portfolio. During the six months ended June 30, 2016, the Fund did not invest in derivative instruments or engage in hedging activities.

Investment Transactions and Investment Income: Investment transactions are accounted for on the trade date. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes. Interest income is recorded on an accrual basis; dividend income is recorded on the ex-dividend date.

Risks Associated with Investments in Other Closed-end Funds: Closed-end investment companies are subject to the risks of investing in the underlying securities. The Fund, as a holder of the securities of the closed-end investment company, will bear its pro rata portion of the closed-end investment company’s expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations.

Taxes: No provision is made for U.S. federal income or excise taxes as it is the Fund’s intention to continue to qualify as a regulated investment company and to make the requisite distributions to its stockholders which will be sufficient to relieve it from all or substantially all U.S. federal income and excise taxes.

The Accounting for Uncertainty in Income Taxes Topic of the FASB Accounting Standards Codification defines the threshold for recognizing the benefits of tax-return positions in the financial statements as “more-likely-than-not” to be sustained by the taxing authority and requires measurement of a tax position meeting the more-likely-than-not criterion, based on the largest benefit that is more than 50 percent likely to be realized. The Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. As of June 30, 2016, the Fund does not have any interest or penalties associated with the underpayment of any income taxes. Management reviewed any uncertain tax positions for open tax years 2013 through 2015, and for the six months ended June 30, 2016. There was no material impact to the financial statements.

Distributions to Stockholders: Effective January 2002, the Fund initiated a fixed, monthly distribution to stockholders. On November 29, 2006, this distribution policy was updated to provide for the annual resetting of the monthly distribution amount per share based on the Fund’s net asset value on the last business day in each October. The terms of the distribution policy will be reviewed and approved at least annually by the Fund’s Board of Directors and can be modified at their discretion. To the extent that these distributions exceed the current earnings of the Fund, the balance will be generated from sales of portfolio securities held by the Fund, which will either be short-term or long- term capital gains, or a tax-free return-of-capital. To the extent these distributions are not represented by net investment income and capital gains, they will not represent yield or investment return on the Fund’s investment portfolio. The Fund plans to maintain this distribution policy even if regulatory requirements would make part of a return-of-capital, necessary to maintain the distribution, taxable to stockholders and to disclose that portion of the distribution that is classified as ordinary income. Although it has no current intention to do so, the Board may terminate this distribution policy at any time and such termination may have an adverse effect on the market price for the Fund’s common shares. The Fund determines annually whether to distribute any net realized long-term capital gains in excess of net realized short-term capital losses, including capital loss carryovers, if any. To the extent that the Fund’s taxable income in any calendar year exceeds the aggregate amount distributed pursuant to this distribution policy, an additional distribution may be made to avoid the payment of a 4% U.S. federal excise tax, and to the extent that the aggregate amount distributed in any calendar year exceeds the Fund’s taxable income, the amount of that excess may constitute a return-of-capital for tax purposes. A return-of-capital distribution reduces the cost basis of an investor’s shares in the Fund. Dividends and distributions to stockholders are recorded by the Fund on the ex-dividend date.

Managed Distribution Risk: Under the managed distribution policy, the Fund makes monthly distributions to stockholders at a rate that may include periodic distributions of its net income and net capital gains (“Net Earnings”), or from return- of-capital. If, for any fiscal year where total cash distributions exceeded Net Earnings (the “Excess”), the Excess would decrease the Fund’s total assets and, as a result, would have the likely effect of increasing the Fund’s expense ratio. There is a risk that the total Net Earnings from the Fund’s portfolio would not be great enough to offset the amount of cash distributions paid to Fund stockholders. If this were to be the case, the Fund’s assets would be depleted, and there is no guarantee that the Fund would be able to replace the assets. In addition, in order to make such distributions, the Fund may have to sell a portion of its investment portfolio at a time when independent investment judgment might not dictate such action. Furthermore, such assets used to make distributions will not be available for investment pursuant to the Fund’s investment objective.

NOTE C. FAIR VALUE

As required by the Fair Value Measurement and Disclosures Topic of the FASB Accounting Standards Codification, the Fund has performed an analysis of all assets and liabilities measured at fair value to determine the significance and character of all inputs to their fair value determination.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into the following three broad categories.

The following is a summary of the inputs used as of June 30, 2016 in valuing the Fund’s investments carried at value:

The breakdown of the Fund’s investments into major categories is disclosed in its Schedule of Investments.

During the six months ended June 30, 2016, the Fund did not have any transfers in and out of any Level.

The Fund did not have any assets or liabilities that were measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at June 30, 2016.

In May 2015, the FASB issued ASU No. 2015-07 “Disclosure for Investments in Certain Entities that Calculate Net Asset Value (“NAV”) 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.

It is the Fund’s policy to recognize transfers into and out of any Level at the end of the reporting period.

NOTE D. AGREEMENTS WITH AFFILIATES

At June 30, 2016 certain officers of the Fund are also officers of Cornerstone or AST Fund Solutions, LLC (“AFS”). Such officers are paid no fees by the Fund for serving as officers of the Fund.

Investment Management Agreement

Cornerstone serves as the Fund’s Investment Manager with respect to all investments. As compensation for its investment management services, Cornerstone receives from the Fund an annual fee, calculated weekly and paid monthly, equal to 1.00% of the Fund’s average weekly net assets. For the six months ended June 30, 2016, Cornerstone earned $532,661 for investment management services.

Administration Agreement

Under the terms of the administration agreement, AFS supplies executive, administrative and regulatory services for the Fund. AFS supervises the preparation of reports to shareholders for the Fund, reports to and filings with the Securities and Exchange Commission and materials for meetings of the Board of Directors. For these services, the Fund pays AFS a monthly fee at an annual rate of 0.075% of its average daily net assets, subject to an annual minimum fee of $50,000. AFS has agreed to discount the annual minimum fee to $30,000 and such discount will remain in place until an amended fee is agreed upon. For the six months ended June 30, 2016, AFS earned $39,950 as administrator.

NOTE E. INVESTMENT IN SECURITIES

For the six months ended June 30, 2016, purchases and sales of securities, other than short-term investments, were $22,003,685 and $32,685,840, respectively.

NOTE F. SHARES OF COMMON STOCK

The Fund has 50,000,000 shares of common stock authorized and 7,762,427 shares issued and outstanding at June 30, 2016. Transactions in common stock for the year ended June 30, 2016 were as follows:

NOTE G. FEDERAL INCOME TAXES

Income and capital gains distributions are determined in accordance with federal income tax regulations, which may differ from GAAP. These differences are primarily due to differing treatments of losses deferred due to wash sales.

The tax character of dividends and distributions paid to stockholders during the year ended December 31, 2015 for the Fund was ordinary income of $798,841, long-term capital gains of $1,674,771 and return of capital of $19,586,472.

GAAP requires that certain components of net assets relating to permanent differences be reclassified etween financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. Under current tax law, certain capital losses realized after October 31

within a taxable year may be deferred and treated as occurring on the first day of the following tax year (“Post-October losses”). The Fund incurred no such losses during the year ended December 31, 2015.

Under the Regulated Investment Company Modernization Act of 2010 (the “Act”), net capital losses recognized after December 31, 2010 may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Under the law in effect prior to the Act, pre-enactment net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. Therefore, there may be a greater likelihood that all or a portion of the Funds’ pre-enactment capital loss carryovers may expire without being utilized.

The following information is computed on a tax basis for each item as of June 30, 2016:

Results of Annual Meeting of Stockholders (unaudited)

On April 19, 2016, the Annual Meeting of Stockholders of the Fund was held and the following matters were voted upon based on 7,676,026 shares of common stock outstanding on the record date of February 22, 2016.

Investment Management Agreement Approval Disclosure (unaudited)

The Board of Directors, including the Independent Directors (the “Board”) of Cornerstone Total Return Fund, Inc. (the “Fund”) considers the approval of the continuation of the Investment Management Agreement (the “Agreement”) between Cornerstone Advisors, Inc. (the “Investment Manager”) and the Fund on an annual basis. The most recent approval of the continuation of the Agreement occurred at an in person meeting of the Board held on February 12, 2016.

The Board requested and received extensive materials and information from the Investment Manager to assist them in considering the approval of the continuance of the Agreement. Based on the Board’s review of the materials and information as well as discussions with management of the Investment Manager, the Board determined that the approval of the continuation of the Agreement was consistent with the best interests of the Fund and its stockholders. The Board decided that the continuation of the Agreement would enable the Fund to continue to receive high quality services at a cost that is appropriate, reasonable, and in the best interests of the Fund and its stockholders. The Board made these determinations on the basis of the following factors, among others: (1) the nature, extent, and quality of the services provided by the Investment Manager; (2) the cost to the Investment Manager for providing such services, with special attention to the Investment Manager’s profitability (and whether the Investment Manager realizes any economies of scale); (3) the direct and indirect benefits received by the Investment Manager from its relationship with the Fund and the other investment companies advised by the Investment Manager; and (4) comparative information as to the management fees, expense ratios and performance of other similarly situated closed-end investment companies.

In response to a questionnaire distributed by Fund counsel to the Investment Manager in accordance with Section 15c of the Investment Company Act of 1940, as amended, the Investment Manager provided certain information to the independent members of the Board in advance of the meeting held on February 12, 2016. The materials provided by the Investment Manager described the services offered by the Investment Manager to the Fund and included an overview of the Investment Manager’s investment philosophy, management style and plan, including the Investment Manager’s extensive knowledge and experience in the closed-end fund industry. The Board noted that the Investment Manager provides quarterly reviews of the performance of the Fund and the Investment Manager’s services for the Fund. The Board also discussed the experience and knowledge of the Investment Manager with respect to managing the Fund’s monthly distribution policy and the extent to which such policy contributes to the market’s positive valuation of the Fund.

The Board also reviewed and discussed a comparison of the Fund’s performance with comparable closed-end funds and a comparison of the Fund’s expense ratios and management fees with those of comparable funds. Additionally, the Investment Manager presented an analysis of its profitability based on its contractual relationship with the Fund and the other investment companies advised by the Investment Manager.

The Board carefully evaluated this information, taking into consideration many factors including the overall high quality of the personnel, operations, financial condition, investment management capabilities, methodologies, and performance of the Investment Manager. The Board met in executive session to discuss the information provided and was advised by independent legal counsel with respect to its deliberations and its duties when considering the Agreement’s continuance. Based on its review of the information requested and provided, the Board determined that the management fees payable to the Investment Manager under the Agreement are fair and reasonable in light of the services to be provided, the performance of the Fund, the profitability of the Investment Manager’s relationship with the Fund, the comparability of the proposed fee to fees paid by closed-end funds in the Fund’s peer group, and the level of quality of the investment management personnel. The Board determined that the Agreement is consistent with the best interests

of the Fund and its stockholders, and enables the Fund to receive high quality services at a cost that is appropriate, reasonable, and in the best interests of the Fund and its stockholders. Accordingly, in light of the above considerations and such other factors and information it considered relevant, the Board by a unanimous vote (including a separate vote of all the independent Board members present in person at the meeting) approved the continuance of the Agreement with respect to the Fund.

Description of Dividend Reinvestment Plan (unaudited)

Cornerstone Total Return Fund, Inc. (the “Fund”) operates a Dividend Reinvestment Plan (the “Plan”), administered by American Stock Transfer & Trust Company, LLC (the “Agent”), pursuant to which the Fund’s income dividends or capital gains or other distributions (each, a “Distribution” and collectively, “Distributions”), net of any applicable U.S. withholding tax, are reinvested in shares of the Fund.

Stockholders automatically participate in the Fund’s Plan, unless and until an election is made to withdraw from the Plan on behalf of such participating stockholder. Stockholders who do not wish to have Distributions automatically reinvested should so notify the Agent at P.O. Box 922, Wall Street Station, New York, New York 10269-0560. Under the Plan, the Fund’s Distributions to stockholders are reinvested in full and fractional shares as described below.

When the Fund declares a Distribution the Agent, on the stockholder’s behalf, will (i) receive additional authorized shares from the Fund either newly issued or repurchased from stockholders by the Fund and held as treasury stock (“Newly Issued Shares”) or (ii) purchase outstanding shares on the open market, on the NYSE MKT or elsewhere, with cash allocated to it by the Fund (“Open Market Purchases”).

The method for determining the number of Newly Issued Shares received when Distributions are reinvested will be determined by dividing the amount of the Distribution either by the Fund’s last reported net asset value per share or by a price equal to the average closing price of the Fund over the five trading days preceding the payment date of the Distribution, whichever is lower. However, if the last reported net asset value of the Fund’s shares is higher than the average closing price of the Fund over the five trading days preceding the payment date of the Distribution (i.e., the Fund is selling at a discount), shares may be acquired by the Agent in Open Market Purchases and allocated to the reinvesting stockholders based on the average cost of such Open Market Purchases. Upon notice from the Fund, the Agent will receive the distribution in cash and will purchase shares of common stock in the open market, on the NYSE MKT or elsewhere, for the participants’ accounts, except that the Agent will endeavor to terminate purchases in the open market and cause the Fund to issue the remaining shares if, following the commencement of the purchases, the market value of the shares, including brokerage commissions, exceeds the net asset value at the time of valuation. These remaining shares will be issued by the Fund at a price equal to the net asset value at the time of valuation.

In a case where the Agent has terminated open market purchases and caused the issuance of remaining shares by the Fund, the number of shares received by the participant in respect of the cash dividend or distribution will be based on the weighted average of prices paid for shares purchased in the open market, including brokerage commissions, and the price at which the Fund issues the remaining shares. To the extent that the Agent is unable to terminate purchases in the open market before the Agent has completed its purchases, or remaining shares cannot be issued by the Fund because the Fund declared a dividend or distribution payable only in cash, and the market price exceeds the net asset value of the shares, the average share purchase price paid by the Agent may exceed the net asset value of the shares, resulting in the acquisition of fewer shares than if the dividend or distribution had been paid in shares issued by the Fund.

Whenever the Fund declares a Distribution and the last reported net asset value of the Fund’s shares is higher than its market price, the Agent will apply the amount of such Distribution payable to Plan participants of the Fund in Fund shares (less such Plan participant’s pro rata share of brokerage commissions incurred with respect to Open Market Purchases in connection with the reinvestment of such Distribution) to the purchase on the open market of Fund shares for such Plan participant’s account. Such purchases will be made on or after the payable date for such Distribution, and in no event more than 30 days after such date except where temporary curtailment or suspension of purchase

Description of Dividend Reinvestment Plan (unaudited) (concluded)

is necessary to comply with applicable provisions of federal securities laws. The Agent may aggregate a Plan participant’s purchases with the purchases of other Plan participants, and the average price (including brokerage commissions) of all shares purchased by the Agent shall be the price per share allocable to each Plan participant.

Registered stockholders who do not wish to have their Distributions automatically reinvested should so notify the Fund in writing. If a stockholder has not elected to receive cash Distributions and the Agent does not receive notice of an election to receive cash Distributions prior to the record date of any Distribution, the stockholder will automatically receive such Distributions in additional shares.

Participants in the Plan may withdraw from the Plan by providing written notice to the Agent at least 30 days prior to the applicable Distribution payment date. The Agent will maintain all stockholder accounts in the Plan and furnish written confirmations of all transactions in the accounts, including information needed by stockholders for personal and tax records. The Agent will hold shares in the account of the Plan participant in non-certificated form in the name of the participant, and each stockholder’s proxy will include those shares purchased pursuant to the Plan. The Agent will distribute all proxy solicitation materials to participating stockholders.

In the case of stockholders, such as banks, brokers or nominees, that hold shares for others who are beneficial owners participating in the Plan, the Agent will administer the Plan on the basis of the number of shares certified from time to time by the record stockholder as representing the total amount of shares registered in the stockholder’s name and held for the account of beneficial owners participating in the Plan.

Neither the Agent nor the Fund shall have any responsibility or liability beyond the exercise of ordinary care for any action taken or omitted pursuant to the Plan, nor shall they have any duties, responsibilities or liabilities except such as expressly set forth herein. Neither shall they be liable hereunder for any act done in good faith or for any good faith omissions to act, including, without limitation, failure to terminate a participants account prior to receipt of written notice of his or her death or with respect to prices at which shares are purchased or sold for the participants account and the terms on which such purchases and sales are made, subject to applicable provisions of the federal securities laws.

The automatic reinvestment of Distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such Distributions. The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan.

Participants may at any time sell some or all of their shares though the Agent. Shares may be sold via the internet at www.amstock.com or through the toll free number. Participants can also use the tear off portion attached to the bottom of their statement and mail the request to American Stock Transfer and Trust Company LLC, P.O Box 922 Wall Street Station, New York, N.Y. 10269-0560. There is a fee of $15.00 per transaction and commission of $0.10 per share.

All correspondence concerning the Plan should be directed to the Agent at P.O. Box 922, Wall Street Station, New York, New York 10269-0560. Certain transactions can be performed online at www.amstock.com or by calling the toll-free number (866) 668-6558.
