[1] The descriptions of the companies and ownership percentages shown in the Consolidated Schedule of Investments were obtained from published reports and other sources believed to be reliable. Acquisition dates indicated are the dates specific securities were acquired, which may differ from the original investment dates. Certain securities were received in exchange for or upon conversion or exercise of other securities previously acquired.
[2] Agreements between certain issuers and the Company provide that the issuer will bear substantially all costs in connection with the disposition of common stock, including those costs involved in registration under the Securities Act of 1933, but excluding underwriting discounts and commissions. These agreements cover common stock owned at March 31, 2012 and common stock which may be acquired thereafter through the exercise of warrants and conversion of debentures and preferred stock. They apply to restricted securities of all issuers in the investment portfolio of the Company except securities of the following issuers which are not obligated to bear registration costs: Humac Company and The Whitmore Manufacturing Company.

[5] The percentages in the "Equity" column express the potential equity interests held by Capital Southwest Corporation and Capital Southwest Venture Corporation (together, the "Company") in each issuer. Each percentage represents the amount of the issuer's common stock the Company owns or can acquire as a percentage of the issuer's total outstanding common stock, plus stock reserved for all warrants, convertible securities and employee stock options.
[6] Unrestricted securities (indicated by ‡) are freely marketable securities having readily available market quotations. All other securities are restricted securities, which are subject to one or more restrictions on resale and are not freely marketable. At March 31, 2012, restricted securities represented approximately 56.9% of the value of the consolidated investment portfolio. Our investments are carried at fair value in accordance with the Investment Company Act of 1940 (the "1940 Act") and FASB Accounting Standards Codification™ (ASC) Topic 820, Fair Value Measurements and Disclosures. In accordance with the 1940 Act, unrestricted minority-owned publicly traded securities, for which the market quotations are readily available, are valued at the closing sale price for the NYSE listed securities and the lower of the closing bid price or the last sale price for NASDAQ securities on the valuation date; and other privately held securities are valued as determined in good faith by our Board of Directors. ASC Topic 820 defines fair value in terms of the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the "exit price") and excludes transaction costs. Under ASC Topic 820, the fair value measurement also assumes that the transaction to sell an asset occurs in the principal market for the asset or, in the absence of a principal market, the most advantageous market for the asset. The principal market is the market in which the reporting entity would sell or transfer the asset with the greatest volume and level of activity for the asset. In determining the principal market for an asset or liability under ASC Topic 820, it is assumed that the reporting entity has access to the market as of the measurement date.
[7] Debt Securities are generally valued on the basis of the price the security would command in order to provide a yield-to-maturity equivalent to the present yield of comparable debt instruments of similar quality. Issuers whose debt securities are judged to be of poor quality and doubtful collectability may instead be valued by assigning percentage discounts commensurate with the quality of such debt securities. Debt securities may also be valued based on the resulting value from the sale of the business at the estimated fair market value. Partnership Interests, Preferred Equity and Common Equity, including unrestricted marketable securities are valued at the closing sale price for the NYSE listed securities and the lower of the closing bid price or the last sale price for NASDAQ securities on the valuation date.For those without a principal market, the Board of Directors considers the financial condition and operating results of the issuer; the long-term potential of the business of the issuer; the market for and recent sales prices of the issuer's securities; the values of similar securities issued by companies in similar businesses; the proportion of the issuer's securities owned by the Company. In determining the fair value of restricted securities, the Board of Directors considers the inherent value of such securities without regard to the restrictive feature and adjusts for any diminution in value resulting from restrictions on resale. Investments in certain entities that calculate net asset value per share (or its equivalent) and for which fair market value is not readily determinable, are valued using the net asset value per share (or its equivalent, such as member units or ownership interest in partners' capital to which a proportionate share of net assets is attributed) of the investment. Equity Warrants are valued on the basis of the Black-Scholes model which defines the market value of a warrant in relation to the market price of its common stock, share price volatility, and time to maturity.
