It is not a prospectus, circular or representation intended for use in the purchase or sale of shares of the Corporation or of any securities mentioned in the report. The rates of return will vary and the principal value of an investment will fluctuate. Shares, if sold, may be worth more or less than their original cost. Past performance is not indicative of future investment results. -------------------------------------------------------------------------------- 4 NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- 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's investment objectives as well as the nature and risk of its investment transactions are set forth in the Corporation's registration statement. Security Valuation--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) are valued at amortized cost. Purchased and written options are valued at the last quoted asked price. Security Transactions and Investment Income--Investment transactions are accounted for on the trade date. Gain or loss on sales of securities and options is determined on the basis of identified cost. Dividend income and distributions to shareholders are recognized on the ex-dividend date, and interest income is recognized on the accrual basis. 2. FEDERAL INCOME TAXES The Corporation's policy is to distribute all of its taxable income to its shareholders in compliance with the requirements of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. For federal income tax purposes, the identified cost of securities at June 30, 2006 was $395,128,519 and net unrealized appreciation aggregated $466,935,589, of which the related gross unrealized appreciation and depreciation were $469,716,003 and $2,780,414, respectively. Distributions are determined in accordance with income tax regulations which may differ from generally accepted accounting principles. Accordingly, annual reclassifications are made within the Corporation's capital accounts to reflect income and gains available for distribution under income tax regulations. 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. Purchases and sales of portfolio securities, other than options and short-term investments, during the six months ended June 30, 2006 were $48,677,573 and $74,249,686, respectively. Options may be written (sold) or purchased by the Corporation. The Corporation, as writer of an option, bears the risks of possible illiquidity of the option markets and from movements in security values. The risk associated with purchasing an option is limited to the premium originally paid. A schedule of outstanding option contracts as of June 30, 2006 can be found on page 12. Transactions in written covered call and collateralized put options during the six months ended June 30, 2006 were as follows: Covered Calls Collateralized Puts --------------------- ------------------- Contracts Premiums Contract Premiums --------- --------- -------- -------- Options outstanding, December 31, 2005 1,940 $292,777 1,050 $129,891 Options written 4,449 478,630 4,370 512,860 Options terminated in closing purchase transactions (250) (61,248) (805) (96,035) Options expired (3,152) (353,637) (2,035) (229,447) Options exercised (1,098) (160,730) (200) (28,649) --------------------------------------------------------------------- Options outstanding, June 30, 2006 1,889 $195,792 2,380 $288,620 --------------------------------------------------------------------- 4. CAPITAL STOCK The Corporation has 5,000,000 authorized and unissued preferred shares without par value. On December 27, 2005, the Corporation issued 438,416 shares of its Common Stock at a price of $33.64 per share (the average market price on December 12, 2005) to stockholders of record on November 22, 2005 who elected to take stock in payment of the year-end distribution from 2005 capital gain and investment income. During 2006, the Corporation issued 164 shares of its Common Stock at a weighted average price of $33.67 per share as dividend equivalents to holders of deferred stock units and restricted stock units under the 2005 Equity Incentive Compensation Plan. The Corporation may purchase shares of its Common Stock from time to time at such prices and amounts as the Board of Directors may deem advisable. 5 NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- Transactions in Common Stock for 2006 and 2005 were as follows: Shares Amount ----------------------- -------------------------- Six months Six months ended Year ended ended Year ended June 30, December 31, June 30, December 31, 2006 2005 2006 2005 --------- ------------ ---------- ------------ Shares issued in payment of dividends 164 438,416 $ 5,722 $ 14,748,314 Shares purchased (at a weighted average discount from net asset value of 9.4% and 8.1%, respectively) (454,700) (806,050) (15,183,841) (24,891,727) Net share activity under the 2005 Equity Incentive Compensation Plan 17,119 9,030 164,495 104,296 ----------------------------------------------------------------------- Net change (437,417) (358,604) $(15,013,624) $(10,039,117) ======================================================================= 5. RETIREMENT PLANS The Corporation's qualified defined benefit pension plan covers all employees with at least one year of service. In addition, the Corporation has a nonqualified defined benefit plan which provides eligible employees with retirement benefits to supplement the qualified plan. Benefits are based on length of service and compensation during the last five years of employment. The Corporation's policy is to contribute annually to the plans those amounts that can be deducted for federal income tax purposes, plus additional amounts as the Corporation deems appropriate in order to provide assets sufficient to meet benefits to be paid to plan participants. During the six months ended June 30, 2006, the Corporation contributed $15,604 to the plans and will contribute an additional $15,604 to the plans during the remainder of 2006. Any further contribution cannot be determined with certainty until certain pension reform legislation, pending in Congress, is passed. Such a contribution, if any, will not exceed $625,000. The following table aggregates the components of the plans' net periodic pension cost for the six months ended June 30, 2006. Service Cost $ 167,438 Interest Cost 163,996 Expected return on plan assets (156,096) Amortization of prior service cost 18,859 Amortization of net loss 112,681 -------------------------------------------------------- Net periodic pension cost $ 306,878 ======================================================== The Corporation also sponsors a defined contribution plan that covers substantially all employees. For the six months ended June 30, 2006, the Corporation expensed contributions of $50,994. The Corporation does not provide postretirement medical benefits. 6. STOCK-BASED COMPENSATION The Stock Option Plan adopted in 1985 ("1985 Plan") permits the issuance of stock options and stock appreciation rights for the purchase of up to 895,522 shares of the Corporations's Common Stock at the fair market value on the date of grant. The exercise price of the options and related stock appreciation rights is reduced by the per share amount of capital gains paid by the Corporation during subsequent years. Options are exercisable beginning not less than one year after the date of grant and stock appreciation rights are exercisable beginning not less than two years after the date of grant. The stock appreciation rights allow the holders to surrender their rights to exercise their options and receive cash or shares in an amount equal to the difference between the option exercise price and the fair market value of the Common Stock at the date of surrender. All options terminate 10 years from the date of grant if not exercised. With the adoption of the 2005 Equity Incentive Compensation Plan at the 2005 Annual Meeting, no further grants will be made under the 1985 Plan, although unexercised awards granted in 2004 and prior years remain outstanding. A summary of option activity under the 1985 Plan as of June 30, 2006, and changes during the period then ended is presented below: Weighted- Weighted- Average Average Exercise Remaining Options Price Life (Years) -------- --------- ------------ Outstanding at December 31, 2005 103,997 $ 18.24 5.07 Exercised (5,186) 14.90 Cancelled (4,474) 20.34 -------------------------------------------------------------- Outstanding at June 30, 2006 94,337 $ 18.22 4.57 -------------------------------------------------------------- Exercisable at June 30, 2006 44,300 $ 17.69 3.92 ============================================================== The options outstanding as of June 30, 2006 are set forth below: Weighted Weighted Average Average Options Exercise Remaining Exercise Price Outstanding Price Life (Years) ------------------------------------------------------------------ $12.50-$14.99 14,398 $ 13.11 1.74 $15.00-$17.49 29,615 16.29 3.96 $17.50-$19.99 18,583 19.45 5.50 $20.00-$22.49 31,741 21.63 5.90 ------------------------------------------------------------------ Outstanding at June 30, 2006 94,337 $ 18.22 4.57 ------------------------------------------------------------------ 6 NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- Compensation cost resulting from stock options and stock appreciation rights granted under the 1985 Plan is based on the intrinsic value of the award, recognized over the award's vesting period, and remeasured at each reporting date through the date of settlement. The total compensation cost recognized for the six months ended June 30, 2006 was $146,623. The 2005 Equity Incentive Compensation Plan ("2005 Plan") permits the grant of stock options, restricted stock awards and other stock incentives to key employees and all non-employee directors. The 2005 Plan provides for the issuance of up to 872,639 shares of the Corporation's Common Stock, including both performance and nonperformance-based restricted stock. Performance-based restricted stock awards vest at the end of a specified three year period, with the ultimate number of awards earned contingent on achievement of certain performance targets. If performance targets are not achieved, all or a portion of the performance-based awards are forfeited and become available for future grants. Nonperformance-based restricted stock awards vest ratably over a three year period and nonperformance-based restricted stock units (granted to non-employee directors) vest over a one year period. The 2005 Plan provides for accelerated vesting in the event of death or retirement. Non-employee directors also may elect to defer a portion of their cash compensation, with such deferred amount to be paid by delivery of deferred stock units. Outstanding awards were granted at fair market value on grant date. The number of shares of Common Stock which remain available for future grants under the 2005 Plan at June 30, 2006 is 846,163 shares. The Corporation pays dividends and dividend equivalents on outstanding awards, which are charged to net assets when paid. Dividends and dividend equivalents paid on restricted awards that are later forfeited are reclassified to compensation expense. A summary of the status of the Corporations's awards granted under the 2005 Plan as of June 30, 2006, and changes during the period then ended is presented below: Weighted Average Shares/ Grant-Date Fair Awards Units Value ------------------------------------------------------------ Balance at December 31, 2005 8,630 $28.35 Granted: Restricted stock 13,025 34.32 Restricted stock units 4,000 33.21 Deferred stock units 584 33.63 Vested & issued (4,260) 28.06 Forfeited (486) 28.06 ------------------------------------------------------------ Balance at June 30, 2006 (includes 13,025 performance-based awards and 8,468 nonperformance-based awards) 21,493 $33.08 ============================================================ Compensation costs resulting from awards granted under the 2005 Plan are based on the fair value of the award on grant date (determined by the average of the high and low price on grant date) and recognized on a straight-line basis over the requisite service period. For those awards with performance conditions, compensation costs are based on the most probable outcome and, if such goals are not met, no compensation cost is recognized and any recognized compensation cost is reversed. The total compensation costs for restricted stock granted to employees for the period ended June 30, 2006 were $81,175. The total compensation costs for restricted stock units granted to non-employee directors for the period ended June 30, 2006 were $80,533. As of June 30, 2006, there were total unrecognized compensation costs of $577,674 related to nonvested share-based compensation arrangements granted under the 2005 Plan. Those costs are expected to be recognized over a weighted average period of 1.98 years. 7. EXPENSES The aggregate remuneration paid during the six months ended June 30, 2006 to officers and directors amounted to $1,378,329, of which $233,587 was paid as fees and compensation to directors who were not officers. These amounts represent the taxable income to the Corporation's officers and directors and therefore differ from the amounts reported in the accompanying Statement of Operations that are recorded and expensed in accordance with generally accepted accounting principles. 8. PORTFOLIO SECURITIES LOANED The Corporation makes loans of securities to brokers, secured by cash deposits, U.S. Government securities, or bank letters of credit. 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. The loans are secured at all times by collateral of at least 102% of the fair value of the securities loaned plus accrued interest. 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.
