1. SIGNIFICANT ACCOUNTING POLICIES

Petroleum & Resources Corporation (the "Corporation") is registered under the Investment Company Act of 1940 as a non-diversified investment company. The Corporation is an internally-managed closed-end fund emphasizing petroleum and other natural resource investments.

Security Transactions - Investment transactions are accounted for on the trade date. Gain or loss on sales of securities and options is determined on the basis of specific identification.

Security Valuation - The Corporation's investments are reported at fair value as defined under accounting principles generally accepted in the United States of America. Investments in securities traded on national security exchanges are valued at the last reported sale price on the day of valuation. Over-the-counter and listed securities for which a sale price is not available are valued at the last quoted bid price. Short-term investments (excluding purchased options and money market funds) are valued at amortized cost, which approximates fair value. Purchased and written options are valued at the last quoted bid and asked price, respectively. Money market funds are valued at net asset value on the day of valuation.

Various inputs are used to determine the fair value of the Corporation's investments. These inputs are summarized as follows:

• Level 1 -- fair value is determined based on market data obtained from independent sources; for example, quoted prices in active markets for identical investments,
• Level 2 -- fair value is determined using other assumptions obtained from independent sources; for example, quoted prices for similar investments,
• Level 3 -- fair value is determined using the Corporation's own assumptions, developed based on the best information available in the circumstances.

The Corporation's investments at March 31, 2012 were classified as follows:

There were no transfers into or from Level 1 or Level 2 during the quarter ended March 31, 2012.

2. FEDERAL INCOME TAXES

For federal income tax purposes, the identified cost of securities at March 31, 2012 was $455,430,072 and net unrealized appreciation aggregated $320,567,241, of which the related gross unrealized appreciation and depreciation were $339,771,411 and $(19,204,170), respectively.

3. INVESTMENT TRANSACTIONS

The Corporation's investment decisions are made by a committee of management, and recommendations to that committee are made by the research staff.

The Corporation is subject to changes in the value of equity securities held ("equity price risk") in the normal course of pursuing its investment objectives. The Corporation may purchase and write option contracts to increase or decrease its equity price risk exposure or may write option contracts to generate additional income. Option contracts generally entail risks associated with counterparty credit, illiquidity, and unfavorable equity price movements. The Corporation has mitigated counterparty credit and illiquidity risks by trading its options through an exchange. The risk of unfavorable equity price movements is limited for purchased options to the premium paid and for written options by writing only covered call or collateralized put option contracts, which require the Corporation to segregate certain securities or cash at its custodian when the option is written.

When the Corporation writes (purchases) an option, an amount equal to the premium received (paid) by the Corporation is recorded as a liability (asset) and is subsequently marked to market daily in the Statement of Assets and Liabilities, with any related change recorded as an unrealized gain or loss in the Statement of Operations. Premiums received (paid) from unexercised options are treated as realized gains (losses) on the expiration date. Upon the exercise of written put (purchased call) option contracts, premiums received (paid) are deducted from (added to) the cost basis of the underlying securities purchased. Upon the exercise of written call (purchased put) option contracts, premiums received (paid) are added to (deducted from) the proceeds from the sale of underlying securities in determining whether there is a realized gain or loss.

4. PORTFOLIO SECURITIES LOANED

The Corporation makes loans of securities to approved brokers to earn additional income. It receives as collateral cash deposits, U.S. Government securities, or bank letters of credit valued at 102% of the value of the securities on loan. The market value of the loaned securities is calculated based upon the most recent closing prices and any additional required collateral is delivered to the Corporation on the next business day. Cash deposits are placed in a registered money market fund. The Corporation accounts for securities lending transactions as secured financing and receives compensation in the form of fees or retains a portion of interest on the investment of any cash received as collateral. The Corporation also continues to receive interest or dividends on the securities loaned. Gain or loss in the fair value of securities loaned that may occur during the term of the loan will be for the account of the Corporation. At March 31, 2012, the Corporation had securities on loan of $11,903,614 and held cash collateral of $12,282,505. The Corporation is indemnified by its lending agent for loss of loaned securities and has the right under the lending agreement to recover the securities from the borrower on demand.
