CENTRAL SECURITIES CORPORATION
NOTES TO STATEMENT OF INVESTMENTS

1. Security Valuation – Marketable common and preferred stocks are valued at the last or closing sale price or, if unavailable, at the closing bid price. Written options are valued at the last quoted asked price. Investments in money market funds are valued at net asset value per share. Securities for which no ready market exists are valued at estimated fair value by the Board of Directors.

As of March 31, 2011, the tax cost of investments was $326,093,908. Net unrealized appreciation was $317,654,801 consisting of gross unrealized appreciation and gross unrealized depreciation of $346,048,362 and $28,393,561, respectively.

2. Fair Value Measurements – The Corporation’s investments and options written are categorized below in three broad hierarchical levels based on market price observability as follows:

The designated Level for a security is not necessarily an indication of the risk associated with investing in that security.

The Corporation’s investments and options written as of March 31, 2011 are classified as shown below:

Level 1

There were no significant transfers of investments between Levels 1, 2, or 3 during the three months ended March 31, 2011. There was no change in the value of or purchases or sales of Level 3 investments during the three months ended March 31, 2011. In valuing Level 3 investments, the Corporation considers the results of various valuation methods, which may include comparable company valuation analyses, discounted future cash flow models and recent private transactions. Consideration is also given to corporate governance, marketability, independent appraisals obtained by portfolio companies, company and industry outlooks and general market conditions. The determination of fair value involves subjective judgments. As a result, using fair value to price a security may result in a price materially different from the price used by other investors or the price that may be realized upon the actual sale of the security.



3. Restricted Securities - The Corporation from time to time invests in securities the resale of which is restricted. The Corporation does not have the right to demand registration of the restricted securities. On March 31, 2011, such investments had an aggregate value of $168,455,000, which was equal to 26.3% of the Corporation’s net assets. Investments in restricted securities at March 31, 2011, including acquisition dates and cost, were:
