Summary of Significant Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES –

Basis of Presentation

In management’s opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting solely of normal recurring adjustments) necessary to present fairly the financial position of Comstock Resources, Inc. and subsidiaries (“Comstock” or the “Company”) as of September 30, 2010 and the related results of operations for the three and nine months ended September 30, 2010 and 2009, and cash flows for the nine months ended September 30, 2010 and 2009.

The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted pursuant to those rules and regulations, although Comstock believes that the disclosures made are adequate to make the information presented not misleading. These unaudited consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in Comstock’s Annual Report on Form 10-K for the year ended December 31, 2009.

The results of operations for the three months and nine months ended September 30, 2010 are not necessarily an indication of the results expected for the full year.

These unaudited consolidated financial statements include the accounts of Comstock and its wholly owned and controlled subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.

Reclassifications

Certain reclassifications have been made to prior periods’ financial statements to conform to the current presentation.

Marketable Securities

As of September 30, 2010 the Company owned 4,797,069 shares of Stone Energy Corporation common stock. The Company does not exert influence over the operating and financial policies of Stone Energy Corporation, and has classified its investment in these shares as an available-for-sale security in the consolidated balance sheets. Available-for-sale securities are accounted for at fair value, with any unrealized gains and unrealized losses not determined to be other than temporary reported in the consolidated balance sheet within accumulated other comprehensive income as a separate component of stockholders’ equity. The Company utilizes the specific identification method to determine the cost of any securities sold. In April 2010 the Company sold 520,000 shares of Stone Energy Corporation and received proceeds of $10.5 million. Comstock realized a gain before income taxes on this sale of $5.7 million which is included in other income (expense) in the consolidated statements of operations.

The Company reviews its available-for-sale securities to determine whether a decline in fair value below the respective cost basis is other than temporary. If the decline in fair value is judged to be other than temporary, the cost basis of the security is written down to fair value and the amount of the write-down is included in the consolidated statement of operations. As of September 30, 2010, the estimated fair value of the Stone Energy Corporation shares, based on the market price for the shares, was $70.7 million after recognizing an unrealized gain after income taxes of $17.3 million.

Reserve for Future Abandonment Costs

Comstock’s asset retirement obligations relate to future plugging and abandonment expenses on its oil and gas properties and related facilities disposal. The following table summarizes the changes in Comstock’s total estimated liability during the nine months ended September 30, 2010 and 2009:


	Nine Months Ended
	September 30,
	2010			2009
	(In thousands)
Beginning future abandonment costs	$	6,561		$	5,480
Accretion expense		290			233
New wells placed on production and changes in estimates		190			342
Liabilities settled		(66	)		(25	)

Future abandonment costs — end of period	$	6,975		$	6,030

Revenue Recognition and Gas Balancing

Comstock utilizes the sales method of accounting for oil and natural gas revenues whereby revenues are recognized at the time of delivery based on the amount of oil or natural gas sold to purchasers. Revenue is typically recorded in the month of production based on an estimate of the Company’s share of volumes produced and prices realized. Revisions to such estimates are recorded as actual results are known. The amount of oil or natural gas sold may differ from the amount to which the Company is entitled based on its revenue interests in the properties. The Company did not have any significant imbalance positions at September 30, 2010 or December 31, 2009.

Derivative Financial Instruments

Comstock periodically uses swaps, floors and collars to hedge oil and natural gas prices and interest rates. Swaps are settled monthly based on differences between the prices specified in the instruments and the settlement prices of futures contracts. Generally, when the applicable settlement price is less than the price specified in the contract, Comstock receives a settlement from the counterparty based on the difference multiplied by the volume or amounts hedged. Similarly, when the applicable settlement price exceeds the price specified in the contract, Comstock pays the counterparty based on the difference. Comstock generally receives a settlement from the counterparty for floors when the applicable settlement price is less than the price specified in the contract, which is based on the difference multiplied by the volume hedged. For collars, generally Comstock receives a settlement from the counterparty when the settlement price is below the floor and pays a settlement to the counterparty when the settlement price exceeds the cap. No settlement occurs when the settlement price falls between the floor and cap.

For the three months and nine months ended September 30, 2009, the Company had natural gas swaps which fixed the price at $8.00 per Mmbtu (at the Houston Ship Channel) for 520,000 Mmbtu’s per month of production. The Company designated these swaps as cash flow hedges. Realized gains of $7.3 million and $20.3 million were included in oil and gas sales for the three months and nine months ended September 30, 2009, respectively, related to these swaps. Changes in the fair value of derivative instruments designated as cash flow hedges, to the extent they were effective in offsetting cash flows attributable to the hedged risk, were recorded in other comprehensive income until the hedged item was recognized in earnings. Any change in fair value resulting from ineffectiveness was recognized in oil and gas sales as an unrealized gain or loss. No amounts relating to the hedge ineffectiveness were recognized in oil and gas sales during the three months and nine months ended September 30, 2009. The Company did not have any derivative financial instruments outstanding during the three months or nine months ended September 30, 2010.

Stock-Based Compensation

Comstock accounts for employee stock-based compensation under the fair value method. Compensation cost is measured at the grant date based on the fair value of the award and is recognized over the award vesting period. During the three months ended September 30, 2010 and 2009, the Company recognized $4.4 million and $4.0 million, respectively, of stock-based compensation expense within general and administrative expenses related to stock option and restricted stock grants. During the nine months ended September 30, 2010 and 2009, the Company recognized $12.9 million and $11.5 million, respectively, of stock-based compensation expense within general and administrative expenses related to stock option and restricted stock grants.

The Company had 246,870 stock options outstanding at September 30, 2010, of which 223,370 were exercisable. Total unrecognized compensation cost related to nonvested stock options of $0.1 million as of September 30, 2010 is expected to be recognized over a period of 0.2 years. The Company received cash proceeds from the exercise of stock options of $1.3 million and $1.5 million for the nine months ended September 30, 2010 and 2009, respectively.

As of September 30, 2010, Comstock had 1,688,000 shares of unvested restricted stock outstanding at a weighted average grant date fair value of $37.22 per share. Total unrecognized compensation cost related to unvested restricted stock grants of $31.9 million as of September 30, 2010 is expected to be recognized over a period of 2.5 years. During the nine months ended September 30, 2010, the Company awarded a total of 36,000 shares of restricted stock to its independent directors which will vest three years from the date of grant. The grant date fair value was $30.49 per share for the 2010 awards.

Income Taxes

The following is an analysis of consolidated income tax expense:


	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2010			2009			2010			2009
				(In thousands)
Current benefit	$	(382	)	$	(26,495	)	$	(199	)	$	(30,618	)
Deferred provision		174			24,302			131			22,318

Benefit from income taxes	$	(208	)	$	(2,193	)	$	(68	)	$	(8,300	)

Deferred income taxes are provided to reflect the future tax consequences or benefits of differences between the tax basis of assets and liabilities and their reported amounts in the financial statements using enacted tax rates. The difference between the Company’s customary rate of 35% and the effective tax rate on income before income taxes is due to the following:


	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2010			2009			2010			2009
Tax at statutory rate		35.0	%		35.0	%		35.0	%		35.0	%
Tax effect of:
Nondeductible stock-based compensation		(26.6	%)		(14.5	%)		(11.9	%)		(10.6	%)
State income taxes, net of federal benefit		(3.1	%)		(3.7	%)		9.0	%		(1.2	%)
Net operating loss carryback adjustments		—	%		—	%		(38.7	%)		—	%
Other		(1.0	%)		(1.9	%)		(0.5	%)		(1.4	%)

Effective tax rate		4.3	%		14.9	%		(7.1	%)		21.8	%

In determining the 2010 full year effective tax rate, the Company is projecting a pre-tax loss. The Company’s non-deductible stock-based compensation has the effect of lowering the Company’s annualized expected tax benefit. In addition, the 2010 effective tax rate reflects a benefit from adjustments related to refund claims resulting from the finalized net operating loss carrybacks in the Company’s 2009 tax returns.

The Company’s income tax returns in major state income tax jurisdictions remain subject to examination from various periods subsequent to December 31, 2005. State tax returns in two state jurisdictions are currently under review. The Company has evaluated the preliminary findings in these jurisdictions and believes it is more likely than not that the ultimate resolution of these matters will not have a material impact on its financial statements. The Company currently believes that all other significant filing positions are highly certain and that all of its other significant income tax positions and deductions would be sustained under audit therefore the Company has no significant reserves for uncertain tax positions.

Fair Value Measurements

As of September 30, 2010, the Company held certain items that are required to be measured at fair value. These included cash equivalents held in money market funds and marketable securities comprised of shares of Stone Energy Corporation common stock. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The estimated fair value for the items in the Company’s financial statement were based on Level 1 inputs where the inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date.

The following table summarizes financial assets and liabilities accounted for at fair value as of September 30, 2010:


	Carrying Value Measured at Fair Value
	(In thousands)
Items measured at fair value on a recurring basis:
Cash equivalents — money market funds	$	4,350
Marketable securities		70,661

Total assets	$	75,011

The following table presents the carrying amounts and estimated fair value of the Company’s other financial instruments as of September 30, 2010 and December 31, 2009:


	As of September 30, 2010				As of December 31, 2009
	Carrying		Fair		Carrying		Fair
	Value		Value		Value		Value
			(In thousands)
Long-term debt, including current portion	$	528,238	$	538,750	$	470,836	$	479,938

The fair market value of the Company’s fixed rate debt was based on their market prices as of September 30, 2010 and December 31, 2009. The fair value of the Company’s floating rate debt approximates its carrying value.

Earnings Per Share

Basic earnings per share is determined without the effect of any outstanding potentially dilutive stock options and diluted earnings per share is determined with the effect of outstanding stock options that are potentially dilutive. Unvested share-based payment awards containing nonforfeitable rights to dividends are considered to be participatory securities and are included in the computation of basic and diluted earnings per share pursuant to the two-class method. Basic and diluted earnings per share for the three months and nine months ended September 30, 2010 and 2009, respectively, were determined as follows:


	Three Months Ended September 30,

At September 30, 2010 and December 31, 2009, 1,688,000 and 2,036,450 shares of restricted stock are included in common stock outstanding as such shares have a nonforfeitable right to participate in any dividends that might be declared and have the right to vote. Weighted average shares of unvested restricted stock were as follows:

The shares of unvested restricted stock were excluded as anti-dilutive to earnings per share in the three months ended September 30, 2010 and the three and nine months ended September 30, 2010 September 30, 2009 due to the net loss in such periods.

Stock options to purchase common stock that were outstanding were excluded as anti-dilutive from the determination of diluted earnings per share as follows:


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2010		2009		2010		2009
	(In thousands except per share data)

Weighted average exercise price	$	36.01	$	23.55	$	36.94	$	22.03

In the three months ended September 30, 2010 and the three and nine months ended September 30, 2009, all stock options were excluded as anti-dilutive to earnings due to the net loss in such periods.

Supplementary Information With Respect to the Consolidated Statements of Cash Flows

For the purpose of the consolidated statements of cash flows, the Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. At September 30, 2010 and December 31, 2009 the Company’s cash investments consisted of prime shares held in institutional preferred money market funds.
