NOTES TO FINANCIAL STATEMENTS (Unaudited)

General American Investors Company, Inc. (the "Company"), established in 1927, is registered under the Investment Company Act of 1940 as a closed-end, diversified management investment company. It is internally managed by its officers under the direction of the Board of Directors.

Equity securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the period. Equity securities reported on the NASDAQ national market are valued at the official closing price on that day. Listed and NASDAQ equity securities for which no sales are reported on that day and other securities traded in the over-the-counter market are valued at the last bid price (asked price for options written) on the valuation date. Equity securities traded primarily in foreign markets are valued at the closing price of such securities on their respective exchanges or markets. Corporate debt securities, domestic and foreign, are generally traded in the over-the-counter market rather than on a securities exchange. The Company utilizes the latest bid prices provided by independent dealers and information with respect to transactions in such securities to assist in determining current market value. If, after the close of foreign markets, conditions change significantly, the price of certain foreign securities may be adjusted to reflect fair value as of the time of the valuation of the portfolio. Investments in money market funds are valued at their net asset value. Special holdings (restricted securities) and other securities for which quotations are not readily available are valued at fair value determined in good faith pursuant to specific procedures appropriate to each security as established by and under the general supervision of the Board of Directors.

The Company may purchase and write (sell) put and call options. The Company typically purchases put options or writes call options to hedge the value of portfolio investments while it typically purchases call options and writes put options to obtain equity market exposure under specified circumstances. The risk associated with purchasing an option is that the Company pays a premium whether or not the option is exercised. Additionally, the Company bears the risk of loss of the premium and a change in market value should the counterparty not perform under the contract. Put and call options purchased are accounted for in the same manner as portfolio securities. Premiums received from writing options are reported as a liability on the Statement of Assets and Liabilities. Those that expire unexercised are treated by the Company on the expiration date as realized gains on written option transactions in the Statement of Operations. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss on written option transactions in the Statement of Operations. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Company has realized a gain or loss on investments in the Statement of Operations. If a put option is exercised, the premium reduces the cost basis for the securities purchased by the Company and is parenthetically disclosed under cost of investments on the Statement of Assets and Liabilities. The Company as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option.

Various data inputs are used in determining the value of the Company’s investments. These inputs are summarized in a hierarchy consisting of the three broad levels listed below:

Level 1 - quoted prices in active markets for identical securities (including money market funds which are valued using amortized cost and which transact at net asset value, typically $1 per share),
Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, credit risk, etc.), and
Level 3 - significant unobservable inputs (including the Company’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following is a summary of the inputs used to value the Company’s net assets as of March 31, 2012:

The aggregate value of Level 3 portfolio investments changed during the three months ended March 31, 2012 as follows:

(a) As of March 31, 2012, an evaluation was performed under the supervision and with the participation of the officers of General American Investors Company, Inc.

(b) There have been no significant changes in the Registrant's internal control over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940 (17 CFR 270.30a-3(d)) that occurred during the Registrant's last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Registrant's internal control over financial reporting.
