KERR-McGEE CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
MARCH 31, 2006


1.
The Company, Basis of Presentation and Accounting Policies

The Company

Kerr-McGee is an independent exploration and production company that explores for, develops, produces and markets crude oil and natural gas, with major areas of operation in the United States and China. Exploration efforts also extend to the North Slope of Alaska and offshore West Africa, Brazil and Trinidad and Tobago. Terms such as “Kerr-McGee,” “the company,” “we,” “our,” and similar terms are used interchangeably in these condensed consolidated financial statements to refer to the consolidated group or to one or more of the companies that are part of the consolidated group.

Recent Developments
 
·  
In January 2006, the company entered into an agreement to sell its interests in Gulf of Mexico shelf oil and natural gas properties to W&T Offshore, Inc. for approximately $1.34 billion in cash, subject to certain adjustments. The transaction, which has an effective date of October 1, 2005 and is subject to customary closing conditions and regulatory approvals, is expected to close in late second quarter or early third quarter.
 
·  
In January 2006, the company's Board of Directors (the Board) approved a $1 billion stock repurchase program. During the first quarter, approximately 3.4 million shares of Kerr-McGee’s stock were repurchased at an aggregate cost of $350 million.
 
·  
In November 2005, Tronox Incorporated (Tronox), a former subsidiary that held Kerr-McGee's chemical business, completed an initial public offering (IPO) of 17.5 million shares of Class A common stock, which reduced Kerr-McGee’s equity interest in Tronox to 57%. On March 30, 2006, Kerr-McGee completed a pro rata distribution to its stockholders in the form of a dividend of shares of Tronox Class B common stock it owned (the Distribution) and no longer has any ownership or voting interest in Tronox.
 
·  
On May 9, 2006, the Board authorized a two-for-one split of Kerr-McGee’s outstanding common stock. The stock split will be accomplished through a stock dividend to be issued on June 14, 2006 to stockholders of record at the close of business on June 2, 2006. Common shares issued and outstanding and earnings per share in the accompanying consolidated financial statements do not give effect to the stock split.
 
·  
The Board also approved a 25% increase in the company's quarterly dividend effective with the dividend payable on July 3, 2006. On a pre-split basis, the quarterly dividend will increase from $.05 per share to $.0625 per share.
 

Basis of Presentation

The unaudited condensed consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and, in the opinion of management, include all adjustments necessary to a fair statement of the results for the interim periods presented. Except for adjustments to reflect the Distribution and reclassifications discussed below, such adjustments are normal and recurring in nature. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. Although the company believes that the disclosures are adequate to make the information presented not misleading, these financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the company's latest annual report on Form 10-K.

With the separation of the chemical business, the income statement format has been changed to better reflect the operations of an exploration and production company.  Certain 2005 amounts included in the accompanying condensed consolidated financial statements have been reclassified to conform to the 2006 presentation. The operating results of and other costs directly associated with Tronox and the company’s North Sea oil and gas business that was sold in November 2005 are reported as discontinued operations.

Accounting Policies

Employee Stock-Based Compensation - Under Kerr-McGee's long-term incentive plans, the company generally grants nonvested stock, stock options and performance unit awards to nonemployee directors and qualifying employees (the terms of the awards are described in Note 9). Prior to 2006, the company’s stock-based employee compensation was accounted for under the recognition and measurement provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (APB No. 25), and related Interpretations, as permitted by Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (FAS No. 123). Under the intrinsic-value-based accounting model specified in APB No. 25, the company generally did not recognize compensation cost for its stock option awards, as most options granted had an exercise price equal to the market value of the underlying common stock on the date of grant.

Effective January 1, 2006, the company adopted the fair value recognition provisions of FAS No. 123 (Revised 2004), “Share-Based Payment” (FAS No. 123(R)), using the modified prospective transition method. Under this method, stock-based compensation cost recognized in income from continuing operations for the three months ended March 31, 2006 includes:
 
·  
Compensation cost for all stock option and stock awards that were unvested as of January 1, 2006 based on the grant-date fair value estimated in accordance with the original provisions of FAS No. 123
 
·  
Compensation cost for all stock options and nonvested stock awards granted subsequent to January 1, 2006 based on the grant-date fair value estimated in accordance with the provisions of FAS No. 123(R)
 
·  
Compensation cost for all performance units (outstanding as of January 1, 2006 and granted subsequent to that date) based on the change in their estimated fair value during the first quarter 2006
 
Results for prior periods have not been restated. The company recognized cumulative effect of adoption as an increase in net income of $2 million ($3 million on a pretax basis). This adjustment reflects a reduction in the performance units liability to its estimated fair value and the effect of the change in the company’s accounting policy for forfeitures. FAS No. 123(R) requires that compensation cost be recognized only for awards for which the requisite service is expected to be rendered, using an estimated forfeiture rate. Prior to January 1, 2006, the company accounted for forfeitures as they occurred.

The following table presents the increase (decrease) in reported earnings for the first quarter of 2006 as a result of adopting FAS No. 123(R), as well as the change in classification of reported cash flows associated with excess tax benefits, as compared to results that would have been reported had the company continued to apply provisions of APB No. 25:

Tronox Separation

In November 2005, Tronox Incorporated, a former subsidiary that held Kerr-McGee's chemical business, completed an initial public offering (IPO) of 17.5 million shares of its Class A common stock. Following the IPO, Kerr-McGee continued to own 22.9 million shares of Tronox Class B common stock, representing approximately 57% of the equity interest and 89% of the total voting power of Tronox. On March 8, 2006, Kerr-McGee's Board of Directors approved a pro rata distribution to its stockholders of Tronox Class B common stock the company owned. The Distribution was completed on March 30, 2006 and resulted in holders of Kerr-McGee common stock as of March 20, 2006 receiving a dividend of .20164 of a share of Tronox Class B common stock for each share of Kerr-McGee common stock they owned. Stockholders entitled to fractional shares of Tronox Class B common stock received cash in lieu of fractional shares. The distribution of Tronox Class B shares in the form of a dividend to the company's stockholders reduced retained earnings and other comprehensive income by a total of $259 million, which represented the carrying amount of Kerr-McGee's investment in Tronox as of the Distribution date.

Under the terms of the Master Separation Agreement entered into between Kerr-McGee and Tronox in connection with the IPO, Kerr-McGee agreed to reimburse Tronox for 50% of certain qualifying environmental remediation costs incurred and paid by Tronox and its subsidiaries before November 28, 2012, subject to certain limitations and conditions. The seven-year reimbursement obligation is limited to a maximum aggregate reimbursement of $100 million. In connection with the Distribution, Kerr-McGee recognized a fair-value-based liability of $56 million associated with this reimbursement obligation, with the associated charge reflected as a component of loss from discontinued operations.

Historically, certain Tronox employees and retirees participated in stock-based compensation, retirement, and health and life postretirement plans established by Kerr-McGee. As more fully discussed in Note 9, except for vested stock options and performance unit awards, Kerr-McGee’s stock-based awards held by Tronox employees were forfeited on the date of the Distribution and replaced with stock-based awards of comparable value issued by Tronox. Additionally, on the Distribution date, Tronox assumed obligations for retirement and health and life postretirement benefits for Tronox’s U.S. employees and retirees. In connection with the assumption of the benefit obligations, the company also transferred to Tronox trust assets associated with the transferred benefit obligations. Note 10 provides additional information regarding the effects of the separation on Kerr-McGee's obligations for pension and postretirement health and life benefits.

5.  Derivative Instruments

The company is exposed to risk from fluctuations in crude oil and natural gas prices, foreign currency exchange rates and interest rates. To reduce the impact of these risks on earnings and to increase the predictability of cash flows, the company enters into derivative contracts primarily comprised of swaps and collars for a portion of its future oil and gas production and interest rate swaps to hedge the fair value of its fixed-rate debt. Effects of interest rate swaps on the company's financial statements were not material for the periods presented.

The following tables summarize the balance sheet presentation of the company’s oil and gas commodity derivatives as of March 31, 2006 and December 31, 2005:

Discontinuation of Hedge Accounting - Because a large portion of the company’s natural gas derivatives no longer qualified for hedge accounting and to increase clarity in its financial statements, the company elected to discontinue hedge accounting prospectively for its commodity derivatives beginning March 1, 2006. Consequently, from that date forward, the company recognizes mark-to-market gains and losses in earnings, rather than deferring such amounts in accumulated other comprehensive income. The net mark-to-market loss on outstanding derivatives at March 31, 2006 included in accumulated other comprehensive income will be reported in future earnings through 2007 as the original hedged oil and gas sales occur. The company expects to reclassify $496 million of the net after-tax derivative loss from accumulated other comprehensive loss to earnings during the next 12 months.

Exploratory Drilling Costs

At March 31, 2006, the company had capitalized exploratory drilling costs of approximately $276 million associated with ongoing exploration and/or appraisal activities primarily in the deepwater Gulf of Mexico, Alaska and Brazil (including $37 million associated with the Gulf of Mexico shelf properties that the company expects to sell, as discussed in Note 1). Such capitalized costs may be charged against earnings in a future period if management determines that commercial quantities of hydrocarbons have not been discovered or that future appraisal drilling or development activities are not likely to occur.

In February 2006, the company redeemed its 7% deep-discount debentures with a face value of $250 million using cash on hand. In connection with the early redemption, a pretax loss of $69 million, representing a write-off of unamortized discount on the debentures, was recognized. Additionally, in January 2006, the company terminated its $1.25 billion secured revolving credit facility, which resulted in a write-off of unamortized debt issue costs of $12 million associated with the facility. The terminated facility was replaced with a $1.25 billion unsecured revolving credit agreement. At March 31, 2006, no borrowings were outstanding under the revolving facility, while outstanding letters of credit that reduce the $1.25 billion borrowing capacity totaled $65 million.

9.  Employee Stock-Based Compensation

Overview - The company's 2005 Long-Term Incentive Plan (the Plan) authorizes the issuance of shares of the company’s common stock to certain employees and non-employee directors at any time prior to May 10, 2015 in the form of fixed-price stock options, restricted stock or performance awards. At March 31, 2006, approximately 8.5 million shares of Kerr-McGee stock were available to be granted under the Plan. Prior to the approval of the Plan by the company’s stockholders, stock-based awards were granted under similar plans, all of which have been terminated. Although no more awards can be issued under those plans, their termination had no effect on awards that had been previously issued and outstanding.

Stock-based awards granted by the company to its employees and non-employee directors in recent years generally have the following terms:

An employee holding stock options vests in one third of the award annually. An employee vests in the entire restricted stock award at the end of the three-year vesting period. Employees terminating their employment due to retirement fully vest in their stock option and restricted stock awards upon retirement; and, subject to certain conditions, retain the right to receive a pro rata payout under the performance units awards to the extent services have been provided.
 
(2)  
Performance unit awards provide an employee with a potential cash payment at the end of a three-year performance cycle based on Kerr-McGee's total stockholder return (stockholder return assuming dividend reinvestment) relative to selected peer companies. Payout levels vary depending upon Kerr-McGee's rank relative to certain peer companies.
 

The following summarizes stock-based compensation expense recognized in income from continuing operations for the three months ended March 31, 2006 and 2005. Stock-based compensation expense recognized in 2006 is based on the fair value of the awards, while in 2005 it reflected the intrinsic value of the awards, if any. Refer to Note 1 for additional information on the change in the accounting policy for stock-based awards.

Effect of Tronox Separation - As provided in the Employee Benefits Agreement between Kerr-McGee and Tronox, except for vested stock options, vested performance unit awards, and awards held by retirement-eligible employees, Kerr-McGee stock-based awards held by Tronox employees at the date of the Distribution were forfeited and replaced with stock-based awards of comparable value issued by Tronox. Retirement-eligible Tronox employees fully vested in their Kerr-McGee stock options and restricted stock on the Distribution date. In connection with the Distribution, pretax expense reversal of $3 million was recognized as a component of loss from discontinued operations, reflecting the net effect of reversing previously recognized compensation cost for Kerr-McGee awards forfeited by Tronox employees and accelerated amortization of compensation cost for awards held by retirement-eligible employees of Tronox.

The holders of Kerr-McGee stock options were not entitled to receive the dividend in the form of Tronox Class B common stock distributed to Kerr-McGee stockholders in March 2006. Accordingly, in connection with the Distribution and following provisions of the relevant plans, the company adjusted the terms of stock options outstanding as of March 30, 2006 to reduce the exercise price and increase the number of shares subject to the options. This antidilution adjustment preserved the intrinsic value of the options and maintained the ratio of the exercise price of each option to the market price of Kerr-McGee stock as of the Distribution. The company evaluated the impact of this award modification on compensation cost and determined that the modification did not increase the fair value of modified options. Therefore, there was no effect on compensation cost recognized in the first quarter of 2006 and no effect is expected on cost recognition in future periods.

Compensation Cost Measurement
 
Valuation and cost attribution methods - Prior to January 1, 2006, the company utilized the Black-Scholes-Merton option-pricing model to estimate the fair value of its stock option awards. Starting with its 2006 grant, the company estimates the fair value of its option awards using a lattice model, which management believes results in a more accurate measurement as compared to the Black-Scholes-Merton formula. Options’ fair value is determined on the date of grant and recognized in earnings (net of expected forfeitures) on a straight-line basis over the employee service period necessary to earn the awards, which is generally the vesting period. However, compensation cost associated with employees whose retention of the options is not contingent on providing future service is recognized immediately upon grant.

Expected Volatility - In setting the volatility assumption, the company considers both the implied volatility of its traded options and historical volatility of its stock price over the same contractual term as the options.
 
Expected Dividend Yield - The dividend yield assumption is based on the company’s expectation, as of the grant date, about its dividend policy over the contractual option term. In March 2005, subsequent to the 2005 stock option grant, Kerr-McGee’s Board of Directors approved a change in the dividend policy that reduced quarterly dividends from $.45 to $.05 per share. The company’s 2006 dividend yield assumption reflects that change in the dividend policy.
 
Expected Term - The expected term represents the period that the company’s options are expected to be outstanding. Under the lattice model, expected term is derived from assumptions of employee post-vesting termination and retirement rates, as well as voluntary exercise behavior correlated to various market price scenarios for the company’s stock. Assumptions made regarding employee exercise behavior are based on analyses of historical experience of similar awards over a period of ten years, giving consideration to the contractual terms of the options, demographic characteristics of option holders, vesting schedules and expectations of future employee behavior.
 
Risk-Free Interest Rate - The company bases the risk-free interest rate on the U.S. Treasury securities over the contractual term of the options.

Includes approximately 73,000 shares forfeited by Tronox employees as of the Distribution date.

Valuation and cost attribution method - Grant-date fair value of nonvested shares is determined by reference to market quotes for the company’s common stock. Compensation cost is recognized in earnings (net of expected forfeitures) on a straight-line basis over the employee service period necessary to earn the awards, which is generally the vesting period. However, compensation cost associated with employees whose retention of stock awards is not contingent on providing future service is recognized immediately upon grant.

(1)  
Grant-date measurement of new performance unit awards is not required to be performed. Rather, fair value of the 2006 grant was estimated as of March 31, 2006 to determine the first quarter 2006 compensation cost associated with these awards.
 
(2)  
Performance units balance represents units outstanding and expected to vest.
 
Valuation and cost attribution method - Fair value estimates as of the end of each reporting period are formed using a Monte Carlo simulation model, which utilizes multiple input variables to determine the probability of satisfying the market condition stipulated in the award terms. Inputs into the model include the following for Kerr-McGee and comparator companies: total stockholder return from the beginning of the performance cycle through the measurement date, volatility, risk-free rates, and correlation of Kerr-McGee's and comparator companies' total stockholder return.  The inputs are based on historical capital market data. The total fair-value-based obligation associated with awards expected to vest is further adjusted to reflect the extent to which employee services necessary to earn the awards have been rendered. Compensation cost for any given period equals the increase or decrease in the liability for awards outstanding and expected to vest.
 
10.  Employee Benefit Plans

Overview - Kerr-McGee is a sponsor of noncontributory defined-benefit retirement plans and contributory postretirement plans for health care and life insurance, in each case for the benefit of the company’s current and former U.S. employees. Most U.S. employees are covered under the company’s retirement plans, and substantially all U.S. employees may become eligible for the health and life postretirement benefits if they reach retirement age while working for the company and have 10 years of continuous service. As discussed in Note 2, under the provisions of the Employee Benefits Agreement between Kerr-McGee and Tronox, qualifying U.S. employees and retirees of Tronox participated in Kerr-McGee’s benefit plans through the date of the Distribution.

Effect of Tronox Separation - In connection with the Tronox separation, Tronox established employee benefit plans for its U.S. employees and retirees and, upon completion of the Distribution, assumed the benefit obligations associated with such employees. For funded U.S. retirement plans, Kerr-McGee also transferred to Tronox trust assets associated with the benefit obligations assumed. Additionally, foreign subsidiaries of Tronox retained their obligations for retirement plans they have sponsored in Germany and the Netherlands.

For Kerr-McGee's U.S. retirement and health and life postretirement plans, assumption of the benefit obligations by Tronox represented a partial settlement of the plan obligations. In connection with the settlement, the benefit obligations for the plans affected by the Tronox separation were remeasured as of March 30, 2006 and assets and liabilities associated with the benefit obligations assumed by Tronox were deconsolidated from Kerr-McGee's consolidated financial statements.

(1)  
Includes plan assets of $441 million transferred from Kerr-McGee’s U.S. qualified retirement plan trust to Tronox on March 30, 2006, the Distribution date. The initial transfer amount was determined based on census information and actuarial estimates as of an earlier date. A final determination of plan assets to be transferred to Tronox based on census data and other information as of the Distribution date will be completed in May 2006 and will result in an incremental transfer of plan assets between Kerr-McGee and Tronox. The company does not expect this incremental transfer to have a material effect on its financial statements.
 
(2)  
Excludes the grantor trust assets of $67 million associated with the company’s supplemental nonqualified U.S. retirement plans.

The trust assets had a balance of $67 million and $50 million at March 31, 2006 and December 31, 2005, respectively. In January 2006, the company made a discretionary contribution to the grantor trust of $22 million. In connection with the Distribution of Tronox, the company transferred $4 million of grantor trust assets to the newly-established Tronox nonqualified benefit plan.

Summarized below are the accumulated benefit obligation, the projected benefit obligation, the market value of plan assets and the funded status of the company’s U.S. qualified retirement plan:
