DEFINITIONS

The following are abbreviations and definitions of terms commonly used in the oil and gas industry and this report. Natural gas equivalents and crude oil equivalents are determined using the ratio of six Mcf to one barrel. All references to “us,” “our,” “we” or “Comstock” mean the registrant, Comstock Resources, Inc. and where applicable, its consolidated subsidiaries.

“Bbl” means a barrel of U.S. 42 gallons of oil.

“Bcf” means one billion cubic feet of natural gas.

“Bcfe” means one billion cubic feet of natural gas equivalent.

“Btu” means British thermal unit, which is the quantity of heat required to raise the temperature of one pound of water from 58.5 to 59.5 degrees Fahrenheit.

“Completion” means the installation of permanent equipment for the production of oil or gas.

“Condensate” means a hydrocarbon mixture that becomes liquid and separates from natural gas when the gas is produced and is similar to crude oil.

“Development well” means a well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive.

“Dry hole” means a well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production exceed production expenses and taxes.

“Exploratory well” means a well drilled to find and produce oil or natural gas reserves not classified as proved, to find a new productive reservoir in a field previously found to be productive of oil or natural gas in another reservoir or to extend a known reservoir.

“GAAP” means generally accepted accounting principles in the United States of America.

“Gross” when used with respect to acres or wells, production or reserves refers to the total acres or wells in which we or another specified person has a working interest.

“MBbls” means one thousand barrels of oil.

“MBbls/d” means one thousand barrels of oil per day.

“Mcf” means one thousand cubic feet of natural gas.

“Mcfe” means one thousand cubic feet of natural gas equivalent.

“MMBbls” means one million barrels of oil.

“MMBtu” means one million British thermal units.

“MMcf” means one million cubic feet of natural gas.

“MMcf/d” means one million cubic feet of natural gas per day.

3

“MMcfe/d” means one million cubic feet of natural gas equivalent per day.

“MMcfe” means one million cubic feet of natural gas equivalent.

“Net” when used with respect to acres or wells, refers to gross acres of wells multiplied, in each case, by the percentage working interest owned by us.

“Net production” means production we own less royalties and production due others.

“Oil” means crude oil or condensate.

“Operator” means the individual or company responsible for the exploration, development, and production of an oil or gas well or lease.

“PV 10 Value” means the present value of estimated future revenues to be generated from the production of proved reserves calculated in accordance with the Securities and Exchange Commission guidelines, net of estimated production and future development costs, using prices and costs as of the date of estimation without future escalation, without giving effect to non-property related expenses such as general and administrative expenses, debt service, future income tax expense and depreciation, depletion and amortization, and discounted using an annual discount rate of 10%. This amount is the same as the standardized measure of discounted future net cash flows related to proved oil and natural gas reserves except that it is determined without deducting future income taxes. Although PV 10 Value is not a financial measure calculated in accordance with GAAP, management believes that the presentation of PV 10 Value is relevant and useful to our investors because it presents the discounted future net cash flows attributable to our proved reserves prior to taking into account corporate future income taxes and our current tax structure. We use this measure when assessing the potential return on investment related to our oil and gas properties. Because many factors that are unique to any given company affect the amount of estimated future income taxes, the use of a pre-tax measure is helpful to investors when comparing companies in our industry.

“Proved developed reserves” means reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery will be included as “proved developed reserves” only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.

“Proved developed non-producing” means reserves (i) expected to be recovered from zones capable of producing but which are shut-in because no market outlet exists at the present time or whose date of connection to a pipeline is uncertain or (ii) currently behind the pipe in existing wells, which are considered proved by virtue of successful testing or production of offsetting wells.

“Proved developed producing” means reserves expected to be recovered from currently producing zones under continuation of present operating methods. This category may also include recently completed shut-in gas wells scheduled for connection to a pipeline in the near future.

“Proved reserves” means the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.

4

“Proved undeveloped reserves” means reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage shall be limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Under no circumstances are estimates for proved undeveloped reserves attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir.

“Recompletion” means the completion for production of an existing well bore in another formation from which the well has been previously completed.

“Reserve life” means the calculation derived by dividing year-end reserves by total production in that year.

“Reserve replacement” means the calculation derived by dividing additions to reserves from acquisitions, extensions, discoveries and revisions of previous estimates in a year by total production in that year.

“Royalty” means an interest in an oil and gas lease that gives the owner of the interest the right to receive a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but generally does not require the owner to pay any portion of the costs of drilling or operating the wells on the leased acreage. Royalties may be either landowner’s royalties, which are reserved by the owner of the leased acreage at the time the lease is granted, or overriding royalties, which are usually reserved by an owner of the leasehold in connection with a transfer to a subsequent owner.

“3-D seismic” means an advanced technology method of detecting accumulations of hydrocarbons identified by the collection and measurement of the intensity and timing of sound waves transmitted into the earth as they reflect back to the surface.

“Tcfe” means one trillion cubic feet of natural gas equivalent.

“Working interest” means an interest in an oil and gas lease that gives the owner of the interest the right to drill for and produce oil and gas on the leased acreage and requires the owner to pay a share of the costs of drilling and production operations. The share of production to which a working interest owner is entitled will always be smaller than the share of costs that the working interest owner is required to bear, with the balance of the production accruing to the owners of royalties. For example, the owner of a 100% working interest in a lease burdened only by a landowner’s royalty of 12.5% would be required to pay 100% of the costs of a well but would be entitled to retain 87.5% of the production.

“Workover” means operations on a producing well to restore or increase production.

PART I

ITEMS 1. and 2.    BUSINESS AND PROPERTIES

We are a Nevada corporation engaged in the acquisition, development, production and exploration of oil and natural gas. Our common stock is listed and traded on the New York Stock Exchange.

Our oil and gas operations are concentrated in East Texas/North Louisiana, South Texas and West Texas. Our oil and natural gas properties are estimated to have proved reserves of 1.3 Tcfe with an estimated PV 10 Value of $1.5 billion as of December 31, 2011 and a standardized measure of discounted future net cash flows of $1.1 billion. Our consolidated proved oil and natural gas reserve base is 85% natural gas and 15% crude oil. Our proved reserves are 46% developed on a Bcfe basis as of December 31, 2011.

Our proved reserves at December 31, 2011 and our 2011 average daily production are summarized below:

	Reserves at December 31, 2011									2011 Average Daily Production
	Oil (MMBbls)		Natural     Gas (Bcf)		Total      (Bcfe)		% of     Total			Oil   (MBbls/d)		Natural Gas (MMcf/d)		Total (MMcfe/d)		% of     Total

Strengths

High Quality Properties.    Our operations are focused in three primary operating areas, the East Texas/North Louisiana, South Texas and West Texas regions. Our properties have an average reserve life of approximately 13.7 years and have extensive development and exploration potential. We have a substantial acreage position in our East Texas/North Louisiana region in the Haynesville or Bossier shale resource play where we have identified 96,090 acres (81,824 net to us) prospective for Haynesville or Bossier shale development. We also have 35,335 acres (27,856 net to us) in South Texas which are prospective for development of the Eagle Ford shale. In 2011 we acquired 89,883 acres (55,466 net to us) in West Texas which are prospective for development of the Wolfcamp shale.

Successful Exploration and Development Program.    In 2011 we spent $829.1 million on exploration and development activities. We drilled 87 wells (47.7 net to us) in 2011 at a cost of $436.3 million and we spent $129.5 million to complete 34 wells that were drilled in 2010. We spent $255.7 million to acquire additional exploratory leases and $0.3 million to acquire seismic data. We also spent $7.3 million for recompletions, workovers, abandonment, production facilities and developmental leasehold. Our drilling activities in 2011 added 228.3 Bcfe to our proved reserves and increased our production by 31% in 2011.

Efficient Operator.    We operate 88% of our proved oil and natural gas reserve base as of December 31, 2011. As operator we are better able to control operating costs, the timing and plans for

6

future development, the level of drilling and lifting costs and the marketing of production. As an operator, we receive reimbursements for overhead from other working interest owners, which reduces our general and administrative expenses.

Successful Acquisitions.    We have had significant growth over the years as a result of our acquisition activity. In 2011, we acquired 164 Bcfe of proved oil and natural gas reserves for $218.7 million. We apply strict economic and reserve risk criteria in evaluating acquisitions. Over the last twenty years, we have added 1.1 Tcfe of proved oil and natural gas reserves from 38 acquisitions at an average cost of $1.17 per Mcfe. Our application of strict economic and reserve risk criteria have enabled us to successfully evaluate and integrate acquisitions.

Business Strategy

Pursue Exploration Opportunities.    We conduct exploration activities to grow our reserve base and to replace our production each year. In late 2007 we identified the potential in our largest operating region, East Texas/North Louisiana, to explore for natural gas in the Haynesville shale, which was below the Cotton Valley, Hosston and Travis Peak sand formations that we have been developing. We drilled eight pilot wells in 2007 and 2008 to evaluate the prospectivity of the Haynesville shale. We undertook an active leasing program to acquire additional acreage in areas we believed would be prospective in the Haynesville shale and spent $238.0 million from 2007 through 2011 to increase our acreage position to 96,090 acres (81,824 net to us) with Haynesville or Bossier shale potential. We started the commercial development of the Haynesville shale in late 2008 and have drilled 180 successful horizontal wells (105.6 net to us) through 2011. In 2011, we drilled 62 Haynesville and Bossier shale horizontal wells (28.0 net to us) which added 139.9 Bcfe to our proved reserves in 2011. With the low natural gas price outlook in 2012, we plan to reduce our natural gas focused drilling. We have budgeted to spend $106.8 million in 2012 to complete 14 Haynesville and Bossier shale horizontal wells (9.8 net to us) that were drilled in 2011 and to drill 17 wells (5.1 net to us).

From 2010 through 2011 we spent approximately $147.7 million to acquire 35,335 acres (27,856 net to us) in South Texas which we believe to be prospective for oil in the Eagle Ford shale formation. We spent approximately $200.7 million to drill 20 wells (19.2 net to us) in 2011 on our Eagle Ford shale properties. Our Eagle Ford shale drilling program added 10.6 million barrels of oil equivalent to our proved reserves in 2011. We plan to continue to develop our Eagle Ford shale properties in 2012 and have budgeted $192.9 million to drill 24 wells (21.7 net to us) during 2012 and to complete four wells that were drilled in 2011.

During 2011 we spent approximately $345.5 million to acquire 70,036 acres (43,591 net to us) in Reeves County in West Texas which we believe to be prospective for oil in the Bone Spring and Wolfcamp shale in the Delaware Basin. This acquisition included 35 producing wells and four wells that were waiting to be completed. The proved reserves acquired with the acquisition were estimated at 25.2 million barrels of oil equivalent. We also spent $8.0 million to acquire 19,847 acres (11,875 net to us) in Gaines County that is prospective for the Wolfcamp shale. We plan to develop these properties during 2012 and have budgeted $158.3 million to drill 43 wells (33.8 net to us) during 2012.

Exploit Existing Reserves.    We seek to maximize the value of our oil and gas properties by increasing production and recoverable reserves through development drilling and workover, recompletion and exploitation activities. We utilize advanced industry technology, including 3-D seismic data, horizontal drilling, improved logging tools, and formation stimulation techniques. During 2011, outside of our Haynesville shale and Eagle Ford shale drilling programs, we spent $2.8 million to drill five wells

7

(0.5 net to us). We also spent $7.3 million for development leasehold, recompletions and workover activity in 2011.

Maintain Flexible Capital Expenditure Budget.    The timing of most of our capital expenditures is discretionary because we have not made any significant long-term capital expenditure commitments except for contracted drilling and completion services. We operate most of the drilling projects in which we participate. Consequently, we have a significant degree of flexibility to adjust the level of such expenditures according to market conditions. We have budgeted to spend approximately $458.0 million on our development and exploration projects in 2012. We intend to primarily use operating cash flow, proceeds from the sale of non-core assets and borrowings under our bank credit facility to fund our development and exploration expenditures in 2012. We may also make additional property acquisitions in 2012 that would require additional sources of funding. Such sources may include borrowings under our bank credit facility or sales of our equity or debt securities.

Acquire High Quality Properties at Attractive Costs.    Historically, we have had a successful track record of increasing our oil and natural gas reserves through opportunistic acquisitions. Over the last twenty years, we have added 1.1 Tcfe of proved oil and natural gas reserves from 38 acquisitions at a total cost of $1.3 billion, or $1.17 per Mcfe. The acquisitions were acquired at an average of 67% of their PV 10 Value in the year the acquisitions were completed. During 2011 we completed two acquisitions of producing oil and gas properties. We acquired 25.2 million barrels of oil equivalent in the Delaware Basin in West Texas for $201.8 million on December 29, 2011. We also acquired 13 Bcfe of proved reserves in North Louisiana for $16.9 million on December 30, 2011. In evaluating acquisitions, we apply strict economic and reserve risk criteria. We target properties in our core operating areas with established production and low operating costs that also have potential opportunities to increase production and reserves through exploration and exploitation activities. We also evaluate our existing properties and consider divesting of non-strategic assets when market conditions are favorable.

(1) Crude oil is converted to natural gas equivalents by using a conversion factor of one barrel of oil for six Mcf of natural gas.

(2) The PV 10 Value represents the discounted future net cash flows attributable to our proved oil and gas reserves before income tax, discounted at 10%. Although it is a non-GAAP measure, we believe that the presentation of the PV 10 Value is relevant and useful to our investors because it presents the discounted future net cash flows attributable to our proved reserves prior to taking into account corporate future income taxes and our current tax structure. We use this measure when assessing the potential return on investment related to our oil and gas properties. The standardized measure of discounted future net cash flows represents the present value of future cash flows attributable to our proved oil and natural gas reserves after income tax, discounted at 10%.

East Texas/North Louisiana Region

Approximately 70% or 917.9 Bcfe of our proved reserves are located in East Texas and North Louisiana where we own interests in 1,010 producing wells (602.9 net to us) in 29 field areas. We operate 679 of these wells.

Oil and Natural Gas Reserves

The following table sets forth our estimated proved oil and natural gas reserves and the PV 10 Value as of December 31, 2011:

	Oil (MBbls)		Natural Gas (MMcf)		Total (MMcfe)		PV 10 Value (000’s)
Proved Developed:
Producing		7,148		434,167		477,054	$	990,258
Non-producing		1,257		116,307		123,852		151,109
Total Proved Developed		8,405		550,474		600,906		1,141,367
Proved Undeveloped		23,694		568,158		710,323		345,606
Total Proved		32,099		1,118,632		1,311,229		1,486,973
Discounted Future Income Taxes								(373,478	)
Standardized Measure of Discounted Future Net Cash Flows(1)							$	1,113,495

(1) The PV 10 Value represents the discounted future net cash flows attributable to our proved oil and natural gas reserves before income tax, discounted at 10%. Although it is a non-GAAP measure, we believe that the presentation of the PV 10 Value is relevant and useful to our investors because it presents the discounted future net cash flows attributable to our proved reserves prior to taking into account corporate future income taxes and our current tax structure. We use this measure when assessing the potential return on investment related to our oil and gas properties. The standardized measure of discounted future net cash flows represents the present value of future cash flows attributable to our proved oil and natural gas reserves after income tax, discounted at 10%.

The following table sets forth our year end reserves as of December 31 for each of the last three fiscal years:

	2009				2010				2011
	Oil (Mbbls)		Natural Gas (MMcf)		Oil (Mbbls)		Natural Gas (MMcf)		Oil (Mbbls)		Natural Gas (MMcf)
Proved Developed		4,894		367,102		2,961		506,809		8,405		550,474
Proved Undeveloped		2,320		315,287		1,258		518,824		23,694		568,158
Total Proved Reserves		7,214		682,389		4,219		1,025,633		32,099		1,118,632

Proved reserves that are attributable to existing producing wells are primarily determined using decline curve analysis and rate transient analysis, which incorporates the principles of hydrocarbon flow. Proved reserves attributable to producing wells with limited production history and for undeveloped locations are estimated using performance from analogous wells in the surrounding area and geologic data to assess the reservoir continuity. Technologies relied on to establish reasonable certainty of economic producibility include, but are not limited to, electrical logs, radioactivity logs, core analyses, geologic maps and available production data, seismic data and well test data.

In connection with estimating proved undeveloped reserves for our December 31, 2011 reserve report, reserves on undrilled acreage were limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled. Using empirical evidence, we utilize control points and sample sizes to show continuity in the reservoir.

There are numerous uncertainties inherent in estimating quantities of proved crude oil and natural gas reserves. Crude oil and natural gas reserve engineering is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be precisely measured. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological

16

interpretation and judgment. Results of drilling, testing and production subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserves estimates are often different from the quantities of crude oil and natural gas that are ultimately recovered.

The average prices that we realized from sales of oil and natural gas, including the effect of hedging, and lifting costs including severance and ad valorem taxes and transportation costs, for each of the last three fiscal years were as follows:

	Year Ended December 31,
	2009		2010		2011
Oil Price — $/Bbl	$	50.94	$	68.35	$	95.73
Natural Gas Price — $/Mcf	$	4.16	$	4.35	$	3.91
Lifting costs — $/Mcfe	$	1.08	$	1.10	$	0.82

The oil and natural gas prices used for reserves estimation were as follows:

Year	Oil Price (per  Bbl)		Natural Gas Price (per Mcf)
2009	$	49.60	$	3.54
2010	$	76.31	$	4.16
2011	$	92.93	$	4.18

Prices used in determining quantities of oil and natural gas reserves and future cash inflows from oil and natural gas reserves represent prices received at the point of sale. These prices have been adjusted from posted prices for both location and quality differences.

Reserves may be classified as proved undeveloped if there is a high degree of confidence that the quantities will be recovered, and they are scheduled to be drilled within five years of their initial inclusion as proved reserves, unless specific circumstances justify a longer time. In addition, undeveloped reserves may be estimated through the use of reliable technology in addition to flow tests and production history. As of December 31, 2011, our proved reserves included 23.7 MMBbls of crude oil and 568 Bcf of natural gas, for a total of 710 Bcfe of undeveloped reserves. Approximately 60% of our proved undeveloped reserves at December 31, 2011 were related to our Haynesville or Bossier shale properties primarily in North Louisiana, 19% was related to our Delaware Basin properties in West Texas and 6% was related to our Eagle Ford shale properties in South Texas. The remaining proved undeveloped reserves are primarily associated with developing reserves in our Cotton Valley and Hosston sand reservoirs in East Texas/North Louisiana and our Wilcox and Vicksburg reservoirs in South Texas. Our 2011 proved undeveloped reserves increased 184 Bcfe from 526 Bcfe at the end of 2010. This increase was primarily due to the 148 Bcfe of proved undeveloped reserves that were acquired in connection with two acquisitions that were completed in December 2011. We also added 98 Bcfe of undeveloped reserves and converted 40 Bcfe of 2010’s undeveloped reserves to proved developed reserves as a result of our 2011 drilling activity. Proved undeveloped reserves were reduced by revisions of 22 Bcfe related to revisions of previous estimates. We spent $56.3 million in 2011 to convert 2010’s undeveloped reserves and $149.1 million to convert 2010’s proved developed nonproducing reserves to proved developed producing reserves. All undeveloped drilling locations which comprise our undeveloped reserves at December 31, 2011 are scheduled to be drilled within five years of the year that such reserves were first included in our reported reserves.

Our estimates of crude oil and natural gas reserves include 342 Bcfe related to undrilled wells that have positive undiscounted future cash flows but which, based upon crude oil and natural gas prices that we use to prepare the proved reserve estimates, have a rate of return that is less than the 10% discount rate used in the Standardized Measure of Discounted Future Cash Flows attributable to the proved reserve

17

estimates. We intend to drill the proved undeveloped wells in the time frame reflected in the estimates of proved oil and natural gas reserves as of December 31, 2011 based upon the crude oil and natural gas prices that we used to prepare the reserve estimates. We anticipate drilling such proved undeveloped locations based on our current development plans for our properties. Certain of these wells may be drilled to retain leasehold interests or to properly manage reservoir performance. To the extent that actual crude oil or natural gas prices are substantially weaker, we may have to modify our development plans or we may not fully recover our investment in drilling these wells from future cash flows.

We had proved reserve additions of 140 Bcfe in 2011 relating to discoveries resulting from our Haynesville and Bossier shale drilling program. These reserve additions related to 96 Bcfe assigned to 62 (28.0 net to us) Haynesville and Bossier shale wells that we drilled and 44 Bcfe assigned to 58 proved undeveloped locations (20.7 net to us) offsetting these wells. During 2011 we continued to drill wells to evaluate our acreage which is prospective for the Eagle Ford shale. Based on the drilling results from our first successful wells, we added 64 Bcfe (88% crude oil) to our proved reserves in 2011. We also had an additional 151 Bcfe (75% crude oil) of reserve additions from our acquisition of properties in West Texas and 13 Bcfe from our acquisition of properties which are prospective for Haynesville or Bossier shale development.

The estimates of our oil and natural gas reserves were determined by Lee Keeling and Associates, Inc. (“Lee Keeling”), an independent petroleum engineering firm. Lee Keeling has been providing consulting engineering and geological services for over fifty years. Lee Keeling’s professional staff is comprised of qualified petroleum engineers who are experienced in all productive areas of the United States. The technical person responsible for review of our reserve estimates at Lee Keeling meets the requirements regarding qualifications, independence, objectivity and confidentiality set forth in the Standards Pertaining to Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. Lee Keeling does not own any interests in our properties and is not employed on a contingent fee basis.

We have established, and maintain, internal controls designed to provide reasonable assurance that the estimates of proved reserves are computed and reported in accordance with rules and regulations promulgated by the SEC. These internal controls include documented process workflows, employing qualified professional engineering and geological personnel, and on-going education for personnel involved in our reserves estimation process. Our internal audit function routinely tests our processes and controls. Inputs to our reserves estimation process, which we provide to Lee Keeling for use in their reserves evaluation, are based upon our historical results for production history, oil and natural gas prices, lifting and development costs, ownership interests and other required data. Our Asset Management Group, comprised of qualified petroleum engineers, works with our accounting, land, marketing and other groups in order to accumulate the information required for the reserves estimation process. During the reserves estimation process our petroleum engineers work with Lee Keeling to ensure that all data we provide is properly reflected in the final reserves estimates and they consult with Lee Keeling throughout the reserves estimation process on technical questions regarding the reserve estimates. We also regularly communicate with Lee Keeling throughout the year about our operations and the potential impact of operational changes and events on our reserve estimates.

Our Asset Manager, who reports to our Vice President of Operations, is the primary person in charge of overseeing our reserve estimates. He has a degree in Petroleum Engineering and has over seventeen years of experience in various technical roles within the oil and gas industry. Working with our Asset Manager is a staff of three petroleum engineering professionals. The average experience of our petroleum engineers is 18 years. Our Vice President of Operations also reviews and approves our final reserve estimates. Our Vice President of Operations has a degree in Petroleum Engineering and has over 27 years of experience holding various technical and managerial roles in the oil and gas industry.

We operate 974 of the 1,711 producing wells presented in the above table. As of December 31, 2011, we owned interests in 16 wells containing multiple completions, which means that a well is producing from more than one completed zone. Wells with more than one completion are reflected as one well in the table above.

Acreage

The following table summarizes our developed and undeveloped leasehold acreage at December 31, 2011, all of which is onshore in the continental United States. We have excluded acreage in which our interest is limited to a royalty or overriding royalty interest.

Expires in 2014	24	%
Thereafter	7	%
	100	%

Title to our oil and natural gas properties is subject to royalty, overriding royalty, carried and other similar interests and contractual arrangements customary in the oil and gas industry, liens incident to operating agreements and for current taxes not yet due and other minor encumbrances. All of our oil and natural gas properties are pledged as collateral under our bank credit facility. As is customary in the oil and gas industry, we are generally able to retain our ownership interest in undeveloped acreage by production of existing wells, by drilling activity which establishes commercial reserves sufficient to maintain the lease, by payment of delay rentals or by the exercise of contractual extension rights. The Company anticipates retaining ownership of a substantial amount of the acreage with primary terms expiring in 2012 through drilling activity or by extending the leases.

Markets and Customers

The market for oil and natural gas produced by us depends on factors beyond our control, including the extent of domestic production and imports of oil and natural gas, the proximity and capacity of natural gas pipelines and other transportation facilities, demand for oil and natural gas, the marketing of competitive fuels and the effects of state and federal regulation. The oil and gas industry also competes

20

with other industries in supplying the energy and fuel requirements of industrial, commercial and individual consumers.

Our oil production is sold under short-term contracts with a duration of six months or less. The contracts require the purchasers to purchase the amount of oil production that is available at prices tied to the spot oil markets. Our natural gas production is primarily sold under contracts with various terms and priced on first of the month index prices or on daily spot market prices. Approximately 85% of our 2011 natural gas sales were priced utilizing first of the month index prices and approximately 15% were priced utilizing daily spot prices. BP Energy Company and its subsidiaries and Shell Oil Company and its subsidiaries accounted for 49% and 14%, respectively, of our total 2011 sales. The loss of either of these customers would not have a material adverse effect on us as there is an available market for our crude oil and natural gas production from other purchasers.

With the significant increase in our natural gas production in North Louisiana due to our Haynesville shale drilling program, we have entered into longer term marketing arrangements to ensure that we have adequate transportation to get our natural gas production to the markets. As an alternative to constructing our own gathering and treating facilities, we have entered into a variety of gathering and treating agreements with midstream companies to transport our natural gas to the long-haul natural gas pipelines. We have dedicated a substantial portion of our production in our Logansport and Toledo Bend fields under such agreements for terms that expire from 2016 to 2020. We have a commitment to transport a minimum of 1.1 Bcf over 3.2 years under one of these agreements.

We have also entered into certain agreements with a major natural gas marketing company to provide us with firm transportation for 80,000 MMBtus per day for our North Louisiana natural gas production on the long-haul pipelines. These agreements expire from 2013 to 2019. To the extent we are not able to deliver the contracted natural gas volumes, we may be responsible for the transportation costs. Our production available to deliver under these agreements in North Louisiana is expected to exceed the firm transportation arrangements we have in place. In addition, the marketing company managing the firm transportation is required to use reasonable efforts to supplement our deliveries should we have a shortfall during the term of the agreements.

Competition

The oil and gas industry is highly competitive. Competitors include major oil companies, other independent energy companies and individual producers and operators, many of which have financial resources, personnel and facilities substantially greater than we do. We face intense competition for the acquisition of oil and natural gas properties and leases for oil and gas exploration.

Regulation

General. Various aspects of our oil and natural gas operations are subject to extensive and continually changing regulation, as legislation affecting the oil and natural gas industry is under constant review for amendment or expansion. Numerous departments and agencies, both federal and state, are authorized by statute to issue, and have issued, rules and regulations binding upon the oil and natural gas industry and its individual members. The Federal Energy Regulatory Commission, or “FERC,” regulates the transportation and sale for resale of natural gas in interstate commerce pursuant to the Natural Gas Act of 1938, or “NGA,” and the Natural Gas Policy Act of 1978, or “NGPA.” In 1989, however, Congress enacted the Natural Gas Wellhead Decontrol Act, which removed all remaining price and nonprice controls affecting all “first sales” of natural gas, effective January 1, 1993, subject to the terms of any private contracts that may be in effect. While sales by producers of natural gas and all sales of crude oil,

21

condensate and natural gas liquids can currently be made at uncontrolled market prices, in the future Congress could reenact price controls or enact other legislation with detrimental impact on many aspects of our business. Under the provisions of the Energy Policy Act of 2005 (the “2005 Act”), the NGA has been amended to prohibit any form of market manipulation with the purchase or sale of natural gas, and the FERC has issued new regulations that are intended to increase natural gas pricing transparency. The 2005 Act has also significantly increased the penalties for violations of the NGA. The FERC has issued Order No. 704 et al. which requires a market participant to make an annual filing if it has sales or purchases equal to or greater than 2.2 million MMBtu in the reporting year to facilitate price transparency.

Regulation and transportation of natural gas.    Our sales of natural gas are affected by the availability, terms and cost of transportation. The price and terms for access to pipeline transportation are subject to extensive regulation. The FERC requires interstate pipelines to provide open-access transportation on a not unduly discriminatory basis for similarly situated shippers. The FERC frequently reviews and modifies its regulations regarding the transportation of natural gas, with the stated goal of fostering competition within the natural gas industry.

Intrastate natural gas transportation is subject to regulation by state regulatory agencies. The Texas Railroad Commission has been changing its regulations governing transportation and gathering services provided by intrastate pipelines and gatherers. While the changes by these state regulators affect us only indirectly, they are intended to further enhance competition in natural gas markets. We cannot predict what further action the FERC or state regulators will take on these matters; however, we do not believe that we will be affected differently in any material respect than other natural gas producers with which we compete by any action taken.

Additional proposals and proceedings that might affect the natural gas industry are pending before Congress, the FERC, state commissions and the courts. The natural gas industry historically has been very heavily regulated; therefore, there is no assurance that the less stringent regulatory approach pursued by the FERC, Congress and state regulatory authorities will continue.

Federal leases.    Some of our operations are located on federal oil and natural gas leases that are administered by the Bureau of Land Management (“BLM”) of the United States Department of the Interior. These leases are issued through competitive bidding and contain relatively standardized terms. These leases require compliance with detailed Department of Interior and BLM regulations and orders that are subject to interpretation and change. These leases are also subject to certain regulations and orders promulgated by the Department of Interior’s Bureau of Ocean Energy Management, Regulation & Enforcement (“BOEMRE”), through its Minerals Revenue Management Program, which is responsible for the management of revenues from both onshore and offshore leases. Additionally, some of our federal leases are subject to the Indian Mineral Development Act of 1982, and are therefore subject to supplemental regulations and orders of the Department of Interior’s Bureau of Indian Affairs. While we cannot predict how various federal agencies may change their interpretations of existing regulations and orders or how regulations and orders issued in the future will impact our operations located on these federal leases, we do not believe we will be affected differently than other similarly situated oil and natural gas producers.

Oil and natural gas liquids transportation rates.    Our sales of crude oil, condensate and natural gas liquids are not currently regulated and are made at market prices. In a number of instances, however, the ability to transport and sell such products is dependent on pipelines whose rates, terms and conditions of service are subject to FERC jurisdiction under the Interstate Commerce Act. In other instances, the ability to transport and sell such products is dependent on pipelines whose rates, terms and conditions of service

22

are subject to regulation by state regulatory bodies under state statutes. The price received from the sale of these products may be affected by the cost of transporting the products to market.

The FERC’s regulation of pipelines that transport crude oil, condensate and natural gas liquids under the Interstate Commerce Act is generally more light-handed than the FERC’s regulation of natural gas pipelines under the NGA. FERC-regulated pipelines that transport crude oil, condensate and natural gas liquids are subject to common carrier obligations that generally ensure non-discriminatory access. With respect to interstate pipeline transportation subject to regulation of the FERC under the Interstate Commerce Act, rates generally must be cost-based, although settlement rates agreed to by all shippers are permitted and market-based rates are permitted in certain circumstances. Effective January 1, 1995, the FERC implemented regulations establishing an indexing system (based on inflation) for transportation rates governed by the Interstate Commerce Act that allowed for an increase or decrease in the transportation rates. The FERC’s regulations include a methodology for such pipelines to change their rates through the use of an index system that establishes ceiling levels for such rates. The mandatory five year review in 2005 revised the methodology for this index to be based on Producer Price Index for Finished Goods (PPI-FG) plus 1.3 percent for the period July 1, 2006 through June 30, 2011. The mandatory five year review in 2011 revised the methodology for this index to be based on PPI-FG plus 2.65 percent for the period July 1, 2011 through June 30, 2016. The regulations provide that each year the Commission will publish the oil pipeline index after the PPI-FG becomes available.

With respect to intrastate crude oil, condensate and natural gas liquids pipelines subject to the jurisdiction of state agencies, such state regulation is generally less rigorous than the regulation of interstate pipelines. State agencies have generally not investigated or challenged existing or proposed rates in the absence of shipper complaints or protests. Complaints or protests have been infrequent and are usually resolved informally.

We do not believe that the regulatory decisions or activities relating to interstate or intrastate crude oil, condensate or natural gas liquids pipelines will affect us in a way that materially differs from the way it affects other crude oil, condensate and natural gas liquids producers or marketers.

Environmental regulations.    We are subject to stringent federal, state and local laws. These laws, among other things, govern the issuance of permits to conduct exploration, drilling and production operations, the amounts and types of materials that may be released into the environment, the discharge and disposition of waste materials, the remediation of contaminated sites and the reclamation and abandonment of wells, sites and facilities. Numerous governmental departments issue rules and regulations to implement and enforce such laws, which are often difficult and costly to comply with and which carry substantial civil and even criminal penalties for failure to comply. Some laws, rules and regulations relating to protection of the environment may, in certain circumstances, impose strict liability for environmental contamination, rendering a person liable for environmental damages and cleanup cost without regard to negligence or fault on the part of such person. Other laws, rules and regulations may restrict the rate of oil and natural gas production below the rate that would otherwise exist or even prohibit exploration and production activities in sensitive areas. In addition, state laws often require various forms of remedial action to prevent pollution, such as closure of inactive pits and plugging of abandoned wells. The regulatory burden on the oil and natural gas industry increases our cost of doing business and consequently affects our profitability. These costs are considered a normal, recurring cost of our on-going operations. Our domestic competitors are generally subject to the same laws and regulations.

We believe that we are in substantial compliance with current applicable environmental laws and regulations and that continued compliance with existing requirements will not have a material adverse impact on our operations. However, environmental laws and regulations have been subject to frequent

23

changes over the years, and the imposition of more stringent requirements or new regulatory schemes such as carbon “cap and trade” programs could have a material adverse effect upon our capital expenditures, earnings or competitive position, including the suspension or cessation of operations in affected areas. As such, there can be no assurance that material cost and liabilities will not be incurred in the future.

The Comprehensive Environmental Response, Compensation and Liability Act, or “CERCLA,” imposes liability, without regard to fault, on certain classes of persons that are considered to be responsible for the release of a “hazardous substance” into the environment. These persons include the current or former owner or operator of the disposal site or sites where the release occurred and companies that disposed or arranged for the disposal of hazardous substances. Under CERCLA, such persons may be subject to joint and several liability for the cost of investigating and cleaning up hazardous substances that have been released into the environment, for damages to natural resources and for the cost of certain health studies. In addition, companies that incur liability frequently also confront third party claims because it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment from a polluted site.

The Federal Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act of 1976, or “RCRA,” regulates the generation, transportation, storage, treatment and disposal of hazardous wastes and can require cleanup of hazardous waste disposal sites. RCRA currently excludes drilling fluids, produced waters and other wastes associated with the exploration, development or production of oil and natural gas from regulation as “hazardous waste.” Disposal of such non-hazardous oil and natural gas exploration, development and production wastes usually are regulated by state law. Other wastes handled at exploration and production sites or used in the course of providing well services may not fall within this exclusion. Moreover, stricter standards for waste handling and disposal may be imposed on the oil and natural gas industry in the future. From time to time, legislation is proposed in Congress that would revoke or alter the current exclusion of exploration, development and production wastes from RCRA’s definition of “hazardous wastes,” thereby potentially subjecting such wastes to more stringent handling, disposal and cleanup requirements. If such legislation were enacted, it could have a significant impact on our operating costs, as well as the oil and natural gas industry in general. The impact of future revisions to environmental laws and regulations cannot be predicted.

Our operations are also subject to the Clean Air Act, or “CAA,” and comparable state and local requirements. Amendments to the CAA were adopted in 1990 and contain provisions that may result in the gradual imposition of certain pollution control requirements with respect to air emissions from our operations. We may be required to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operating permits and approvals for air emissions. However, we believe our operations will not be materially adversely affected by any such requirements, and the requirements are not expected to be any more burdensome to us than to other similarly situated companies involved in oil and natural gas exploration and production activities.

The Federal Water Pollution Control Act of 1972, as amended, or the “Clean Water Act,” imposes restrictions and controls on the discharge of produced waters and other wastes into navigable waters. Permits must be obtained to discharge pollutants into state and federal waters and to conduct construction activities in waters and wetlands. Certain state regulations and the general permits issued under the Federal National Pollutant Discharge Elimination System program prohibit the discharge of produced waters and sand, drilling fluids, drill cuttings and certain other substances related to the oil and natural gas industry into certain coastal and offshore waters, unless otherwise authorized. Further, the EPA has adopted regulations requiring certain oil and natural gas exploration and production facilities to obtain permits for storm water discharges. Costs may be associated with the treatment of wastewater or

24

developing and implementing storm water pollution prevention plans. The Clean Water Act and comparable state statutes provide for civil, criminal and administrative penalties for unauthorized discharges for oil and other pollutants and impose liability on parties responsible for those discharges for the cost of cleaning up any environmental damage caused by the release and for natural resource damages resulting from the release. We believe that our operations comply in all material respects with the requirements of the Clean Water Act and state statutes enacted to control water pollution.

Federal regulators require certain owners or operators of facilities that store or otherwise handle oil to prepare and implement spill prevention, control, countermeasure and response plans relating to the possible discharge of oil into surface waters. The Oil Pollution Act of 1990 (“OPA”) contains numerous requirements relating to the prevention and response to oil spills in the waters of the United States. The OPA subjects owners of facilities to strict joint and several liability for all containment and cleanup costs and certain other damages relating to a spill. Noncompliance with OPA may result in varying civil and criminal penalties and liabilities.

Executive Order 13158, issued on May 26, 2000, directs federal agencies to safeguard existing Marine Protected Areas, or “MPAs,” in the United States and establish new MPAs. The order requires federal agencies to avoid harm to MPAs to the extent permitted by law and to the maximum extent practicable. It also directs the EPA to propose new regulations under the Clean Water Act to ensure appropriate levels of protection for the marine environment. This order has the potential to adversely affect our operations by restricting areas in which we may carry out future exploration and development projects and/or causing us to incur increased operating expenses.

Certain flora and fauna that have officially been classified as “threatened” or “endangered” are protected by the Endangered Species Act. This law prohibits any activities that could “take” a protected plant or animal or reduce or degrade its habitat area. If endangered species are located in an area we wish to develop, the work could be prohibited or delayed and/or expensive mitigation might be required.

Other statutes that provide protection to animal and plant species and which may apply to our operations include, but are not necessarily limited to, the Oil Pollution Act, the Emergency Planning and Community Right to Know Act, the Marine Mammal Protection Act, the Marine Protection, Research and Sanctuaries Act, the Fish and Wildlife Coordination Act, the Fishery Conservation and Management Act, the Migratory Bird Treaty Act and the National Historic Preservation Act. These laws and regulations may require the acquisition of a permit or other authorization before construction or drilling commences and may limit or prohibit construction, drilling and other activities on certain lands lying within wilderness or wetlands and other protected areas and impose substantial liabilities for pollution resulting from our operations. The permits required for our various operations are subject to revocation, modification and renewal by issuing authorities. In addition, laws such as the National Environmental Policy Act and the Coastal Zone Management Act may make the process of obtaining certain permits more difficult or time consuming, resulting in increased costs and potential delays that could affect the viability or profitability of certain activities.

Certain statutes such as the Emergency Planning and Community Right to Know Act require the reporting of hazardous chemicals manufactured, processed, or otherwise used, which may lead to heightened scrutiny of the company’s operations by regulatory agencies or the public. In 2011, the EPA adopted a new reporting requirement, the Petroleum and Natural Gas Systems Greenhouse Gas Reporting Rule (40 C.F.R. Part 98, Subpart W), which requires certain onshore petroleum and natural gas facilities to begin collecting data on their emissions of greenhouse gases (“GHGs”) in January 2011, with the first annual reports of those emissions due on March 31, 2012. GHGs include gases such as methane, a primary component of natural gas, and carbon dioxide, a byproduct of burning natural gas. Different GHGs have different global warming potentials with CO₂ having the lowest

25

global warming potential, so emissions of GHGs are typically expressed in terms of CO₂ equivalents, or CO₂e. The rule applies to facilities that emit 25,000 metric tons of CO₂e or more per year, and requires onshore petroleum and natural gas operators to group all equipment under common ownership or control within a single hydrocarbon basin together when determining if the threshold is met. We have determined that these new reporting requirements apply to us and we are implementing procedures to collect the required information.

Such changes in environmental laws and regulations which result in more stringent and costly reporting, or waste handling, storage, transportation, disposal or cleanup activities, could materially affect companies operating in the energy industry. Adoption of new regulations further regulating emissions from oil and gas production could adversely affect our business, financial position, results of operations and prospects, as could the adoption of new laws or regulations which levy taxes or other costs on greenhouse gas emissions from other industries, which could result in changes to the consumption and demand for natural gas. We may also be assessed administrative, civil and/or criminal penalties if we fail to comply with any such new laws and regulations applicable to oil and natural gas production.

We maintain insurance against “sudden and accidental” occurrences, which may cover some, but not all, of the risks described above. Most significantly, the insurance we maintain will not cover the risks described above which occur over a sustained period of time. Further, there can be no assurance that such insurance will continue to be available to cover all such cost or that such insurance will be available at a cost that would justify its purchase. The occurrence of a significant event not fully insured or indemnified against could have a material adverse effect on our financial condition and results of operations.

Regulation of oil and natural gas exploration and production.    Our exploration and production operations are subject to various types of regulation at the federal, state and local levels. Such regulations include requiring permits and drilling bonds for the drilling of wells, regulating the location of wells, the method of drilling and casing wells and the surface use and restoration of properties upon which wells are drilled. Many states also have statutes or regulations addressing conservation matters, including provisions for the unitization or pooling of oil and natural gas properties, the establishment of maximum rates of production from oil and natural gas wells and the regulation of spacing, plugging and abandonment of such wells. Some state statutes limit the rate at which oil and natural gas can be produced from our properties.

State regulation.    Most states regulate the production and sale of oil and natural gas, including requirements for obtaining drilling permits, the method of developing new fields, the spacing and operation of wells and the prevention of waste of oil and gas resources. The rate of production may be regulated and the maximum daily production allowable from both oil and gas wells may be established on a market demand or conservation basis or both.

ITEM 1A.     RISK FACTORS

You should carefully consider the following risk factors as well as the other information contained or incorporated by reference in this report, as these important factors, among others, could cause our actual results to differ from our expected or historical results. It is not possible to predict or identify all such factors. Consequently, you should not consider any such list to be a complete statement of all of our potential risks or uncertainties.

A substantial or extended decline in oil and natural gas prices may adversely affect our business, financial condition, cash flow, liquidity or results of operations and our ability to meet our capital expenditure obligations and financial commitments and to implement our business strategy.

Our business is heavily dependent upon the prices of, and demand for, oil and natural gas. Historically, the prices for oil and natural gas have been volatile and are likely to remain volatile in the future. The prices we receive for our oil and natural gas production and the level of such production will be subject to wide fluctuations and depend on numerous factors beyond our control, including the following:

• the domestic and foreign supply of oil and natural gas;

• weather conditions;

29

• the price and quantity of imports of crude oil and natural gas;

• political conditions and events in other oil-producing and natural gas-producing countries, including embargoes, hostilities in the Middle East and other sustained military campaigns, and acts of terrorism or sabotage;

• the actions of the Organization of Petroleum Exporting Countries, or OPEC;

• domestic government regulation, legislation and policies;

• the level of global oil and natural gas inventories;

• technological advances affecting energy consumption;

• the price and availability of alternative fuels; and

• overall economic conditions.

If the decline in the price of natural gas that first started in 2008 continues through 2012, the lower prices will adversely affect:

• our revenues, profitability and cash flow from operations;

• the value of our proved oil and natural gas reserves;

• the economic viability of certain of our drilling prospects;

• our borrowing capacity; and

• our ability to obtain additional capital.

We have entered into certain oil price hedging arrangements on certain of our anticipated sales. In the future we may enter into additional hedging arrangements in order to reduce our exposure to price risks. Such arrangements would limit our ability to benefit from increases in oil and natural gas prices.

The recent recession could have a material adverse impact on our financial position, results of operations and cash flows.

The oil and gas industry is cyclical and tends to reflect general economic conditions. The United States and other countries have been in a recession which could continue through 2012 and beyond, and the capital markets have experienced significant volatility. The recession has had an adverse impact on demand and pricing for crude oil and natural gas. A continuation of the recession could have a further negative impact on oil and natural gas prices. Our operating cash flows and profitability will be significantly affected by declining oil and natural gas prices. Further declines in oil and natural gas prices may also impact the value of our oil and gas reserves, which could result in future impairment charges to reduce the carrying value of our oil and gas properties and our marketable securities. Our future access to capital could be limited due to tightening credit markets and volatile capital markets. If our access to capital is limited, development of our assets may be delayed or limited, and we may not be able to execute our growth strategy.

Our future production and revenues depend on our ability to replace our reserves.

Our future production and revenues depend upon our ability to find, develop or acquire additional oil and natural gas reserves that are economically recoverable. Our proved reserves will generally decline as reserves are depleted, except to the extent that we conduct successful exploration or development activities or acquire properties containing proved reserves, or both. To increase reserves and production, we must continue our acquisition and drilling activities. We cannot assure you, however, that our acquisition and drilling activities will result in significant additional reserves or that we will have continuing success drilling productive wells at low finding and development costs. Furthermore, while our revenues may increase if prevailing oil and natural gas prices increase significantly, our finding costs for additional reserves could also increase.

30

Prospects that we decide to drill may not yield oil or natural gas in commercially viable quantities or quantities sufficient to meet our targeted rate of return.

A prospect is a property in which we own an interest or have operating rights and that has what our geoscientists believe, based on available seismic and geological information, to be an indication of potential oil or natural gas. Our prospects are in various stages of evaluation, ranging from a prospect that is ready to be drilled to a prospect that will require substantial additional evaluation and interpretation. There is no way to predict in advance of drilling and testing whether any particular prospect will yield oil or natural gas in sufficient quantities to recover drilling or completion costs or to be economically viable. The use of seismic data and other technologies and the study of producing fields in the same area will not enable us to know conclusively prior to drilling whether oil or natural gas will be present or, if present, whether oil or natural gas will be present in commercial quantities. The analysis that we perform using data from other wells, more fully explored prospects and/or producing fields may not be useful in predicting the characteristics and potential reserves associated with our drilling prospects. If we drill additional unsuccessful wells, our drilling success rate may decline and we may not achieve our targeted rate of return.

Federal and state legislation and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional operating restrictions or delays as well as restrict our access to our oil and gas reserves.

Hydraulic fracturing is an essential and common practice that is used to stimulate production of oil and natural gas from dense subsurface rock formations such as shale and tight sands. We routinely apply hydraulic fracturing techniques in completing our wells. The process involves the injection of water, sand and additives under pressure into a targeted subsurface formation. The water and pressure create fractures in the rock formations, which are held open by the grains of sand, enabling the oil or natural gas to flow to the wellbore. The use of hydraulic fracturing is necessary to produce commercial quantities of crude oil and natural gas from many reservoirs including the Haynesville shale, Bossier shale, Eagle Ford shale, Wolfcamp shale, Bone Spring, Cotton Valley and other tight natural gas and oil reservoirs. Substantially all of our proved oil and gas reserves that are currently not producing and our undeveloped acreage require hydraulic fracturing to be productive. All of the wells being drilled by us in 2012 utilize hydraulic fracturing in their completion. We estimate we will incur approximately $185.0 million for hydraulic fracturing services in connection with our 2012 drilling and completion program.

The use of hydraulic fracturing in our well completion activities could expose us to liability for negative environmental effects that might occur. Although we have not had any incidents related to hydraulic fracturing operations that we believe have caused any negative environmental effects, we have established operating procedures to respond and report any unexpected fluid discharge which might occur during our operations, including plans to remediate any spills that might occur. In the event that we were to suffer a loss related to hydraulic fracturing operations, our insurance will be net of a $25,000 deductible and our ability to recover costs will be limited to a total aggregate policy limit of $26.0 million, which may or may not be sufficient to pay the full amount of our losses incurred.

Drilling and completion activities are typically regulated by state oil and natural gas commissions. Our drilling and completion activities are conducted primarily in Louisiana and Texas. Texas adopted a law in June 2011 requiring disclosure to the Railroad Commission of Texas and the public of certain information regarding the components used in the hydraulic-fracturing process. Several proposals are before the United States Congress that, if implemented, would subject the process of hydraulic fracturing to regulation under the Safe Drinking Water Act. At the direction of Congress, the EPA is currently

31

conducting an extensive, multi-year study into the potential effects of hydraulic fracturing on underground sources of drinking water, and the results of that study have the potential to impact the likelihood or scope of future legislation or regulation.

Potential changes to US federal tax regulations, if passed, could have an adverse effect on us.

The United States Congress continues to consider imposing new taxes and repeal of many tax incentives and deductions that are currently used by independent oil and gas producers. Examples of changes being considered that would impact us are: elimination of the ability to fully deduct intangible drilling costs in the year incurred, repeal of the manufacturing tax deduction for oil and gas companies, increasing the geological and geophysical cost amortization period, and implementation of a fee on non-producing leases located on federal lands. If these proposals are enacted, our current income tax liability will increase, potentially significantly, which would have a negative impact on our cash flow from operating activities. A reduction in operating cash flow could require us to reduce our drilling activities. Since none of these proposals have yet to be included in new legislation, we do not know the ultimate impact they may have on our business.

Our debt service requirements could adversely affect our operations and limit our growth.

We had $1.2 billion in debt as of December 31, 2011, and our ratio of total debt to total capitalization was approximately 54%.

Our outstanding debt will have important consequences, including, without limitation:

• a portion of our cash flow from operations will be required to make debt service payments;

• our ability to borrow additional amounts for working capital, capital expenditures (including acquisitions) or other purposes will be limited; and

• our debt could limit our ability to capitalize on significant business opportunities, our flexibility in planning for or reacting to changes in market conditions and our ability to withstand competitive pressures and economic downturns.

In addition, future acquisition or development activities may require us to alter our capitalization significantly. These changes in capitalization may significantly increase our debt. Moreover, our ability to meet our debt service obligations and to reduce our total debt will be dependent upon our future performance, which will be subject to general economic conditions and financial, business and other factors affecting our operations, many of which are beyond our control. If we are unable to generate sufficient cash flow from operations in the future to service our indebtedness and to meet other commitments, we will be required to adopt one or more alternatives, such as refinancing or restructuring our indebtedness, selling material assets or seeking to raise additional debt or equity capital. We cannot assure you that any of these actions could be effected on a timely basis or on satisfactory terms or that these actions would enable us to continue to satisfy our capital requirements.

Our bank credit facility contains a number of significant covenants. These covenants will limit our ability to, among other things:

• borrow additional money;

• merge, consolidate or dispose of assets;

• make certain types of investments;

• enter into transactions with our affiliates; and

• pay dividends.

32

Our failure to comply with any of these covenants could cause a default under our bank credit facility and the respective indentures governing our 8 ³/8% senior notes due 2017 and 7 ³/4% senior notes due 2019. A default, if not waived, could result in acceleration of our indebtedness, in which case the debt would become immediately due and payable. If this occurs, we may not be able to repay our debt or borrow sufficient funds to refinance it given the current status of the credit markets. Even if new financing is available, it may not be on terms that are acceptable to us. Complying with these covenants may cause us to take actions that we otherwise would not take or not take actions that we otherwise would take.

The unavailability or high cost of drilling rigs, equipment, supplies or qualified personnel and oilfield services could adversely affect our ability to execute our exploration and development plans on a timely basis and within our budget.

Our industry has experienced a shortage of drilling rigs, equipment, supplies and qualified personnel in recent years as the result of higher demand for these services. Costs and delivery times of rigs, equipment and supplies have been substantially greater than they were several years ago. In addition, demand for, and wage rates of, qualified drilling rig crews have escalated due to the higher activity levels. Shortages of drilling rigs, equipment or supplies or qualified personnel in the areas in which we operate could delay or restrict our exploration and development operations, which in turn could adversely affect our financial condition and results of operations because of our concentration in those areas.

Our business involves many uncertainties and operating risks that can prevent us from realizing profits and can cause substantial losses.

Our future success will depend on the success of our exploration and development activities. Exploration activities involve numerous risks, including the risk that no commercially productive natural gas or oil reserves will be discovered. In addition, these activities may be unsuccessful for many reasons, including weather, cost overruns, equipment shortages and mechanical difficulties. Moreover, the successful drilling of a natural gas or oil well does not ensure we will realize a profit on our investment. A variety of factors, both geological and market-related, can cause a well to become uneconomical or only marginally economical. In addition to their costs, unsuccessful wells can hurt our efforts to replace production and reserves.

Our business involves a variety of operating risks, including:

• unusual or unexpected geological formations;

• fires;

• explosions;

• blow-outs and surface cratering;

• uncontrollable flows of natural gas, oil and formation water;

• natural disasters, such as hurricanes, tropical storms and other adverse weather conditions;

• pipe, cement, or pipeline failures;

• casing collapses;

• mechanical difficulties, such as lost or stuck oil field drilling and service tools;

• abnormally pressured formations; and

• environmental hazards, such as natural gas leaks, oil spills, pipeline ruptures and discharges of toxic gases.

If we experience any of these problems, well bores, gathering systems and processing facilities could be affected, which could adversely affect our ability to conduct operations.

33

We could also incur substantial losses as a result of:

• injury or loss of life;

• severe damage to and destruction of property, natural resources and equipment;

• pollution and other environmental damage;

• clean-up responsibilities;

• regulatory investigation and penalties;

• suspension of our operations; and

• repairs to resume operations.

We pursue acquisitions as part of our growth strategy and there are risks in connection with acquisitions.

Our growth has been attributable in part to acquisitions of producing properties and companies. We expect to continue to evaluate and, where appropriate, pursue acquisition opportunities on terms we consider favorable. However, we cannot assure you that suitable acquisition candidates will be identified in the future, or that we will be able to finance such acquisitions on favorable terms. In addition, we compete against other companies for acquisitions, and we cannot assure you that we will successfully acquire any material property interests. Further, we cannot assure you that future acquisitions by us will be integrated successfully into our operations or will increase our profits.

The successful acquisition of producing properties requires an assessment of numerous factors beyond our control, including, without limitation:

• recoverable reserves;

• exploration potential;

• future oil and natural gas prices;

• operating costs; and

• potential environmental and other liabilities.

In connection with such an assessment, we perform a review of the subject properties that we believe to be generally consistent with industry practices. The resulting assessments are inexact and their accuracy uncertain, and such a review may not reveal all existing or potential problems, nor will it necessarily permit us to become sufficiently familiar with the properties to fully assess their merits and deficiencies. Inspections may not always be performed on every well, and structural and environmental problems are not necessarily observable even when an inspection is made.

Additionally, significant acquisitions can change the nature of our operations and business depending upon the character of the acquired properties, which may be substantially different in operating and geologic characteristics or geographic location than our existing properties. While our current operations are focused in the East Texas/North Louisiana, South Texas and West Texas regions, we may pursue acquisitions or properties located in other geographic areas.

We operate in a highly competitive industry, and our failure to remain competitive with our competitors, many of which have greater resources than we do, could adversely affect our results of operations.

The oil and natural gas industry is highly competitive in the search for and development and acquisition of reserves. Our competitors often include companies that have greater financial and personnel resources than we do. These resources could allow those competitors to price their products and services more aggressively than we can, which could hurt our profitability. Moreover, our ability to acquire additional properties and to discover reserves in the future will be dependent upon our ability to evaluate and select suitable properties and to close transactions in a highly competitive environment.

34

Our competitors may use superior technology that we may be unable to afford or which would require costly investment by us in order to compete.

If our competitors use or develop new technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to implement new technologies at a substantial cost. In addition, our competitors may have greater financial, technical and personnel resources that allow them to enjoy technological advances and may in the future allow them to implement new technologies before we can. We cannot be certain that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. One or more of the technologies that we currently use or that we may implement in the future may become obsolete. All of these factors may inhibit our ability to acquire additional prospects and compete successfully in the future.

Substantial exploration and development activities could require significant outside capital, which could dilute the value of our common shares and restrict our activities. Also, we may not be able to obtain needed capital or financing on satisfactory terms, which could lead to a limitation of our future business opportunities and a decline in our oil and natural gas reserves.

We expect to expend substantial capital in the acquisition of, exploration for and development of oil and natural gas reserves. In order to finance these activities, we may need to alter or increase our capitalization substantially through the issuance of debt or equity securities, the sale of non-strategic assets or other means. The issuance of additional equity securities could have a dilutive effect on the value of our common shares, and may not be possible on terms acceptable to us given the current volatility in the financial markets. The issuance of additional debt would require that a portion of our cash flow from operations be used for the payment of interest on our debt, thereby reducing our ability to use our cash flow to fund working capital, capital expenditures, acquisitions, dividends and general corporate requirements, which could place us at a competitive disadvantage relative to other competitors. Additionally, if our revenues decrease as a result of lower oil or natural gas prices, operating difficulties or declines in reserves, our ability to obtain the capital necessary to undertake or complete future exploration and development programs and to pursue other opportunities may be limited, which could result in a curtailment of our operations relating to exploration and development of our prospects, which in turn could result in a decline in our oil and natural gas reserves.

If oil prices decline and natural gas prices remain low or continue to decline, we may be required to write-down the carrying values and/or the estimates of total reserves of our oil and natural gas properties, which would constitute a non-cash charge to earnings and adversely affect our results of operations.

Accounting rules applicable to us require that we review periodically the carrying value of our oil and natural gas properties for possible impairment. Based on specific market factors and circumstances at the time of prospective impairment reviews and the continuing evaluation of development plans, production data, economics and other factors, we may be required to write down the carrying value of our oil and natural gas properties. A write-down constitutes a non-cash charge to earnings. We may incur non-cash charges in the future, which could have a material adverse effect on our results of operations in the period taken. We may also reduce our estimates of the reserves that may be economically recovered, which could have the effect of reducing the total value of our reserves. Such a reduction in carrying value could impact our borrowing ability and may result in accelerating the repayment date of any outstanding debt.

35

Our reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in our reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.

Reserve engineering is a subjective process of estimating the recovery from underground accumulations of oil and natural gas that cannot be precisely measured. The accuracy of any reserve estimate depends on the quality of available data, production history and engineering and geological interpretation and judgment. Because all reserve estimates are to some degree imprecise, the quantities of oil and natural gas that are ultimately recovered, production and operating costs, the amount and timing of future development expenditures and future oil and natural gas prices may all differ materially from those assumed in these estimates. The information regarding present value of the future net cash flows attributable to our proved oil and natural gas reserves is only estimated and should not be construed as the current market value of the oil and natural gas reserves attributable to our properties. Thus, such information includes revisions of certain reserve estimates attributable to proved properties included in the preceding year’s estimates. Such revisions reflect additional information from subsequent activities, production history of the properties involved and any adjustments in the projected economic life of such properties resulting from changes in product prices. Any future downward revisions could adversely affect our financial condition, our borrowing ability, our future prospects and the value of our common stock.

As of December 31, 2011, 54% of our total proved reserves were undeveloped and 9% were developed non-producing. These reserves may not ultimately be developed or produced. Furthermore, not all of our undeveloped or developed non-producing reserves may be ultimately produced at the time periods we have planned, at the costs we have budgeted, or at all. As a result, we may not find commercially viable quantities of oil and natural gas, which in turn may result in a material adverse effect on our results of operations.

If we are unsuccessful at marketing our oil and natural gas at commercially acceptable prices, our profitability will decline.

Our ability to market oil and natural gas at commercially acceptable prices depends on, among other factors, the following:

• the availability and capacity of gathering systems and pipelines;

• federal and state regulation of production and transportation;

• changes in supply and demand; and

• general economic conditions.

Our inability to respond appropriately to changes in these factors could negatively affect our profitability.

Market conditions or operational impediments may hinder our access to oil and natural gas markets or delay our production.

Market conditions or the unavailability of satisfactory oil and natural gas transportation arrangements may hinder our access to oil and natural gas markets or delay our production. The availability of a ready market for our oil and natural gas production depends on a number of factors, including the demand for and supply of oil and natural gas and the proximity of reserves to pipelines and processing facilities. Our ability to market our production depends in a substantial part on the availability and capacity of gathering systems, pipelines and processing facilities, in some cases owned and operated by third parties. Our failure to obtain such services on acceptable terms could materially harm our

36

business. We may be required to shut in wells for a lack of a market or because of the inadequacy or unavailability of pipelines or gathering system capacity. If that were to occur, then we would be unable to realize revenue from those wells until arrangements were made to deliver our production to market.

We depend on our key personnel and the loss of any of these individuals could have a material adverse effect on our operations.

We believe that the success of our business strategy and our ability to operate profitably depend on the continued employment of M. Jay Allison, our President and Chief Executive Officer, and a limited number of other senior management personnel. Loss of the services of Mr. Allison or any of those other individuals could have a material adverse effect on our operations.

Our insurance coverage may not be sufficient or may not be available to cover some liabilities or losses that we may incur.

If we suffer a significant accident or other loss, our insurance coverage will be net of our deductibles and may not be sufficient to pay the full current market value or current replacement value of our lost investment, which could result in a material adverse impact on our operations and financial condition. Our insurance does not protect us against all operational risks. We do not carry business interruption insurance. For some risks, we may not obtain insurance if we believe the cost of available insurance is excessive relative to the risks presented. Because third party drilling contractors are used to drill our wells, we may not realize the full benefit of workers’ compensation laws in dealing with their employees. In addition, some risks, including pollution and environmental risks, generally are not fully insurable.

We are subject to extensive governmental laws and regulations that may adversely affect the cost, manner or feasibility of doing business.

Our operations and facilities are subject to extensive federal, state and local laws and regulations relating to the exploration for, and the development, production and transportation of, oil and natural gas, and operating safety. Future laws or regulations, any adverse changes in the interpretation of existing laws and regulations or our failure to comply with existing legal requirements may harm our business, results of operations and financial condition. We may be required to make large and unanticipated capital expenditures to comply with governmental laws and regulations, such as:

• lease permit restrictions;

• drilling bonds and other financial responsibility requirements, such as plug and abandonment bonds;

• spacing of wells;

• unitization and pooling of properties;

• safety precautions;

• regulatory requirements; and

• taxation.

Under these laws and regulations, we could be liable for:

• personal injuries;

• property and natural resource damages;

• well reclamation costs; and

• governmental sanctions, such as fines and penalties.

37

Our operations could be significantly delayed or curtailed and our cost of operations could significantly increase as a result of regulatory requirements or restrictions. We are unable to predict the ultimate cost of compliance with these requirements or their effect on our operations.

Our operations may incur substantial liabilities to comply with environmental laws and regulations.

Our oil and natural gas operations are subject to stringent federal, state and local laws and regulations relating to the release or disposal of materials into the environment and otherwise relating to environmental protection. These laws and regulations:

• require the acquisition of one or more permits before drilling commences;

• impose limitations on where drilling can occur and/or requires mitigation before authorizing drilling in certain locations;

• restrict the types, quantities and concentration of substances that can be released into the environment in connection with drilling and production activities;

• require reporting of significant releases, and annual reporting of the nature and quantity of emissions, discharges and other releases into the environment;

• limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other protected areas; and

• impose substantial liabilities for pollution resulting from our operations.

Failure to comply with these laws and regulations may result in:

• the assessment of administrative, civil and criminal penalties;

• the incurrence of investigatory or remedial obligations; and

• the imposition of injunctive relief.

In June 2009 the United States House of Representatives passed the American Clean Energy and Security Act of 2009. A similar bill, the Clean Energy Jobs and American Power Act, introduced in the Senate, has not passed. Both bills contain the basic feature of establishing a “cap and trade” system for restricting greenhouse gas emissions in the United States. Under such a system, certain sources of greenhouse gas emissions would be required to obtain greenhouse gas emission “allowances” corresponding to their annual emissions of greenhouse gases. The number of emission allowances issued each year would decline as necessary over time to meet overall emission reduction goals. As the number of greenhouse gas emission allowances declines each year, the cost or value of allowances is expected to escalate significantly. It appears that the prospects for a cap and trade system such as that proposed in these bills have dimmed significantly since the 2011 midterm elections; however, the EPA is moving ahead with its efforts to regulate GHG emissions from certain sources by rule. The EPA has issued Subpart W of the Final Mandatory Reporting of Greenhouse Gases Rule, which required petroleum and natural gas systems that emit 25,000 metric tons of CO₂e or more per year to begin collecting GHG emissions data under a new reporting system beginning on January 1, 2011 with the first annual report due March 31, 2012. We are required to report under these new regulations, and are implementing the required procedures to collect the required information. Beyond measuring and reporting, the EPA issued an “Endangerment Finding” under section 202(a) of the Clean Air Act, concluding greenhouse gas pollution threatens the public health and welfare of current and future generations. The EPA has adopted regulations that would require permits for and reductions in greenhouse gas emissions for certain facilities. Since all of our crude oil and natural gas production is in the United States, these laws or regulations that have been or may be adopted to restrict or reduce emissions of greenhouse gases could require us to incur substantial increased operating costs, and could have an adverse effect on demand for the crude oil and natural gas we produce.

38

In June 2011 the Bureau of Land Management issued a proposed oil and gas leasing reform. The proposal would require, among other things, a more detailed environmental review prior to leasing oil and natural gas resources on federal lands, increased public engagement in the development of Master Leasing Plans prior to leasing areas where intensive new oil and gas development is anticipated, and a comprehensive parcel review process with greater public involvement in the identification of key environmental resource values before a parcel is leased. New leases would incorporate adaptive management stipulations, requiring lessees to monitor and respond to observed environmental impacts, possibly through the implementation of expensive new control measures or curtailment of operations, potentially reducing profitability. The proposed policy could have the effect of reducing the amount of new federal lands made available for lease, increasing the competition for and cost of available parcels.

Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly restrictions on emissions, and/or waste handling, storage, transport, disposal or cleanup requirements could require us to make significant expenditures to reach and maintain compliance and may otherwise have a material adverse effect on our industry in general and on our own results of operations, competitive position or financial condition. Under these environmental laws and regulations, we could be held strictly liable for the removal or remediation of previously released materials or property contamination regardless of whether we were responsible for the release or contamination or if our operations met previous standards in the industry at the time they were performed. Future environmental laws and regulations, including proposed legislation regulating climate change, may negatively impact our industry. The costs of compliance with these requirements may have an adverse impact on our financial condition, results of operations and cash flows.

Provisions of our articles of incorporation, bylaws and Nevada law will make it more difficult to effect a change in control of us, which could adversely affect the price of our common stock.

Nevada corporate law and our articles of incorporation and bylaws contain provisions that could delay, defer or prevent a change in control of us. These provisions include:

• allowing for authorized but unissued shares of common and preferred stock;

• a classified board of directors;

• requiring special stockholder meetings to be called only by our chairman of the board, our chief executive officer, a majority of the board or the holders of at least 10% of our outstanding stock entitled to vote at a special meeting;

• requiring removal of directors by a supermajority stockholder vote;

• prohibiting cumulative voting in the election of directors; and

• Nevada control share laws that may limit voting rights in shares representing a controlling interest in us.

These provisions could make an acquisition of us by means of a tender offer or proxy contest or removal of our incumbent directors more difficult. As a result, these provisions could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders, which may limit the price that investors are willing to pay in the future for shares of our common stock.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our selected historical consolidated financial data and our accompanying consolidated financial statements and the notes to those financial statements included elsewhere in this report. The following discussion includes forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed below and elsewhere in this report, particularly in “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”

Overview

We are an independent energy company engaged in the acquisition, exploration, development and production of oil and natural gas in the United States. We own interests in 1,711 producing oil and natural gas wells (925.6 net to us) and we operate 974 of these wells. In managing our business, we are concerned primarily with maximizing return on our stockholders’ equity. To accomplish this goal, we focus on profitably increasing our oil and natural gas reserves and production.

Our future growth will be driven primarily by acquisition, development and exploration activities. In 2011 our growth in production and proved reserves was primarily driven by our successful drilling activities in the Haynesville/Bossier shale and Eagle Ford shale formations and the acquisitions we completed in 2011. Under our current drilling budget, we plan to spend approximately $458.0 million in 2012 for development and exploration activities which will primarily be focused on oil by developing our Delaware Basin properties in West Texas and our Eagle Ford shale properties in South Texas. We plan to drill 84 wells (60.6 net to us) in 2012 of which 43 wells will be in the Delaware Basin, 24 will be horizontal Eagle Ford shale wells and 17 will be Haynesville or Bossier shale wells. However, we could increase or decrease the number of wells that we drill depending on oil and natural gas prices. We do not specifically budget for acquisitions as the timing and size of acquisitions are not predictable.

43

We use the successful efforts method of accounting, which allows only for the capitalization of costs associated with developing proven oil and natural gas properties as well as exploration costs associated with successful exploration activities. Accordingly, our exploration costs consist of costs we incur to acquire and reprocess 3-D seismic data, impairments of our unevaluated leasehold where we were not successful in discovering reserves and the costs of unsuccessful exploratory wells that we drill.

We generally sell our oil and natural gas at current market prices at the point our wells connect to third party purchaser pipelines. We have entered into certain gathering and treating agreements with midstream companies to transport a substantial portion of our natural gas production in North Louisiana, to long-haul gas pipelines. In addition, we have also entered into agreements for firm transportation of 80,000 MMBtus per day of natural gas on long-haul pipelines. We market our products several different ways depending upon a number of factors, including the availability of purchasers for the product, the availability and cost of pipelines near our wells, market prices, pipeline constraints and operational flexibility. Accordingly, our revenues are heavily dependent upon the prices of, and demand for, oil and natural gas. Oil and natural gas prices have historically been volatile and are likely to remain volatile in the future.

Our operating costs are generally comprised of several components, including costs of field personnel, insurance, repair and maintenance costs, production supplies, fuel used in operations, transportation costs, workover expenses and state production and ad valorem taxes.

Like all oil and natural gas exploration and production companies, we face the constant challenge of replacing our reserves. Although in the past we have offset the effect of declining production rates from existing properties through successful acquisition and drilling efforts, there can be no assurance that we will be able to continue to offset production declines or maintain production at current rates through future acquisitions or drilling activity. Our future growth will depend on our ability to continue to add new reserves in excess of production.

Our operations and facilities are subject to extensive federal, state and local laws and regulations relating to the exploration for, and the development, production and transportation of, oil and natural gas, and operating safety. Future laws or regulations, any adverse changes in the interpretation of existing laws and regulations or our failure to comply with existing legal requirements may have an adverse effect on our business, results of operations and financial condition. Applicable environmental regulations require us to remove our equipment after production has ceased, to plug and abandon our wells and to remediate any environmental damage our operations may have caused. The present value of the estimated future costs to plug and abandon our oil and gas wells and to dismantle and remove our production facilities is included in our reserve for future abandonment costs, which was $14.0 million as of December 31, 2011.

Results of Operations

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010

Our operating data for 2010 and 2011 is summarized below:

	Year Ended December 31,
	2010		2011
Net Production Data:
Natural gas (MMcf)		68,973		90,593
Oil (MBbls)		715		838
Natural gas equivalent (MMcfe)		73,262		95,622
Average Sales Price:
Oil ($/Bbl)		$68.35		$95.73
Natural gas ($/Mcf)		$4.35		$3.91
Average equivalent price ($/Mcfe)		$4.77		$4.54
Expenses ($ per Mcfe):

Depreciation, depletion and amortization(2)		$2.91		$3.00

(1) Includes ad valorem taxes.

(2) Represents depreciation, depletion and amortization of oil and gas properties only.

Oil and gas sales.    Our oil and gas sales increased $85.2 million (24%) in 2011 to $434.4 million from sales of $349.1 million in 2010. This increase resulted from higher natural gas production and higher prices realized for crude oil sales in 2011. Our production in 2011 increased by 31% over 2010’s production as our successful drilling in the Haynesville/Bossier and Eagle Ford shale formations exceeded declines from our existing producing properties. Prices realized for crude oil sales increased by 40% in 2011 as compared to 2010 while the average price we realized for natural gas sales decreased by 10% in 2011 as compared to 2010. During 2011 we drilled 87 wells (47.7 net to us), 62 of which were Haynesville or Bossier shale horizontal wells and 20 of which were Eagle Ford shale horizontal wells. At December 31, 2011 we had 23 wells (15.5 net to us) that were drilled in 2011 awaiting completion.

Production taxes.    Production taxes decreased $6.2 million (63%) to $3.7 million in 2011 from $9.9 million in 2010. Our Haynesville and Bossier shale wells, which comprise a large percentage of our production, qualify for exemption from certain state production taxes. The exempt wells together with the lower natural gas prices account for the decrease.

Gathering and transportation.    Gathering and transportation costs in 2011 increased $11.2 million (65%) to $28.5 million as compared to $17.3 million in 2010 due to the transportation costs related to the higher production from our Haynesville/Bossier shale properties in North Louisiana.

Lease operating expenses.    Our lease operating expenses, including ad valorem taxes, of $46.6 million in 2011 were $6.9 million or 13% lower than our operating expenses of $53.5 million in 2010. Our lease operating expense per Mcfe produced decreased by 33% to $0.48 per Mcfe in 2011 as compared to $0.72 per Mcfe in 2010. The decreases in lease operating expenses are primarily due to the sale of our higher operating cost properties in Mississippi in 2010.

Exploration expense.    We incurred $10.1 million in exploration expense in 2011 as compared to $2.6 million in 2010. Exploration expense in 2011 consisted of $9.8 million of impairments of unevaluated leasehold costs and $0.3 million for the acquisition of seismic data. Our 2010 exploration cost primarily related to costs incurred for the acquisition of seismic data.

45

Depreciation, depletion and amortization expense (“DD&A”).    DD&A of $290.8 million increased $77.0 million (36%) as compared to DD&A of $213.8 million in 2010. Our DD&A rate per Mcfe produced averaged $3.00 in 2011 as compared to $2.91 for 2010. The increase in DD&A primarily resulted from our 31% growth in production in 2011.

Impairment of oil and gas properties.    We recorded impairments to our oil and gas properties of $60.8 million and $0.2 million in 2011 and 2010, respectively. These impairments relate to fields where an impairment was indicated based on estimated future cash flows from the properties. The 2011 impairment is a result of lower anticipated natural gas prices.

General and administrative expenses.    General and administrative expense of $35.2 million for 2011 was 5% lower than general and administrative expense of $37.2 million for 2010. The decrease primarily reflects our lower personnel costs in 2011. Stock based compensation decreased by $2.4 million to $15.0 million in 2011 as compared to $17.4 million in 2010.

Interest expense.    Interest expense increased $13.2 million (45%) to $42.7 million in 2011 from interest expense of $29.5 million in 2010. The increase was primarily related to the increase in outstanding debt during 2011 including the issuance of $300.0 million in senior notes in March 2011. Average borrowings under our bank credit facility increased to $121.4 million in 2011 as compared to $70.0 million for 2010. The average interest rate on the outstanding borrowings under our credit facility of 2.2% in 2011 was unchanged from 2010. We capitalized interest of $13.2 million and $13.0 million in 2011 and 2010, respectively, which reduced interest expense. Interest expense in 2011 includes $1.1 million for the early retirement of our 6 ⁷/8% senior notes which were due in March 2012.

Income taxes.    The benefit from income taxes increased in 2011 to $14.6 million from $4.8 million in 2010 due to the higher net loss in 2011. Our effective tax rate of 30% in 2011 and 20% in 2010 differed from the federal income tax rate of 35% primarily due to the effect of nondeductible compensation and state income taxes.

Net loss.    We reported a loss of $33.5 million for 2011 as compared to a loss of $19.6 million for 2010. The loss per share for 2011 was $0.73 on weighted average shares outstanding of 46.0 million as compared to a loss per share of $0.43 for 2010 on weighted average shares outstanding of 45.6 million. The loss in 2011 was primarily related to the impairments to proved and unproved properties in 2011 of $70.6 million ($45.9 million after income taxes) offset in part by gains on sales of marketable securities of $35.1 million ($22.8 million after income taxes). The loss in 2010 was primarily related to the loss on our divestiture of oil and gas properties in Mississippi of $25.8 million ($16.8 million after income taxes).

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009

Our operating data for 2009 and 2010 is summarized below:

	Year Ended December 31,
	2009		2010
Net Production Data:
Natural gas (MMcf)		60,820		68,973
Oil (MBbls)		775		715

Depreciation, depletion and amortization(2)		$3.25		$2.91

(1) Includes ad valorem taxes.

(2) Represents depreciation, depletion and amortization of oil and gas properties only.

Oil and gas sales.    Our oil and gas sales increased $56.5 million (19%) in 2010 to $349.1 million from sales of $292.6 million in 2009. This increase resulted from higher natural gas production and higher prices realized for natural gas and crude oil in 2010. Our production in 2010 increased by 12% over 2009’s production as our successful drilling in the Haynesville shale exceeded declines from our existing producing properties. The average price for natural gas we realized increased by 5% in 2010 as compared to 2009. Prices for crude oil increased by 34% in 2010 as compared to 2009. During 2010 we drilled 72 (45.0 net to us) Haynesville or Bossier shale horizontal wells. At December 31, 2010 we had 35 (23.4 net to us) of these wells awaiting completion. These wells were not completed in 2010 due to the unavailability of pressure pumping completion services.

Production taxes.    Production taxes increased $1.3 million (14%) to $9.9 million in 2010 from $8.6 million in 2009. The increase was due to higher oil and natural gas prices and from higher production in 2010.

Gathering and transportation.    Gathering and transportation costs in 2010 increased $8.6 million (98%) to $17.3 million as compared to $8.7 million in 2009 due to the transportation costs related to production from our Haynesville shale properties in North Louisiana.

Lease operating expenses.    Our lease operating expenses, including ad valorem taxes, of $53.5 million in 2010 were comparable to our operating expenses of $53.6 million in 2009. Oil and gas operating expenses per equivalent Mcf produced decreased to $0.72 as compared to $0.82 in 2009. The decrease in our per unit rate reflects our higher production level in 2010.

Exploration expense.    We had $2.6 million in exploration expense in 2010 as compared to $0.9 million in 2009. Exploration expense in 2010 and 2009 primarily related to costs incurred for the acquisition of seismic data.

DD&A.     DD&A of $213.8 million was comparable to DD&A of $213.2 million in 2009. Our DD&A rate per Mcfe produced averaged $2.91 in 2010 as compared to $3.25 for 2009. The increase in

47

DD&A resulting from our 12% growth in production was mostly offset by the decrease in our amortization rate which resulted from our reserve growth and lower finding and development costs in 2010.

Impairment of oil and gas properties.    We recorded minor impairments to our oil and gas properties of $0.2 million and $0.1 million in 2010 and 2009, respectively. These impairments relate to fields where an impairment was indicated based on estimated future cash flows from the properties.

General and administrative expenses.    General and administrative expense of $37.2 million for 2010 was 5% lower than general and administrative expense of $39.2 million for 2009. The decrease primarily reflects our lower personnel costs in 2010 and $1.0 million in acquisition evaluation costs incurred in 2009.

Interest expense.     Interest expense increased $13.4 million (83%) to $29.5 million in 2010 from interest expense of $16.1 million in 2009. The increase was primarily the result of interest on our senior notes issued in October 2009 which was partially offset by lower outstanding borrowings under our bank credit facility and an increase in capitalized interest related to our unevaluated properties. Average borrowings under our bank credit facility decreased to $70.0 million in 2010 as compared to $116.8 million for 2009. The average interest rate on the outstanding borrowings under our credit facility increased to 2.2% in 2010 as compared to 2.1% in 2009. We capitalized interest of $13.0 million and $6.6 million in 2010 and 2009, respectively, which reduced interest expense.

Income taxes.     Income tax expense decreased in 2010 to a benefit of $4.8 million from a benefit of $10.8 million in 2009. Our effective tax rate of 19.8% in 2010 and 22.8% in 2009 differed from the federal income tax rate of 35% primarily due to the effect of nondeductible compensation and state income taxes.

Net loss.     We reported a loss of $19.6 million for 2010 as compared to a loss of $36.5 million for 2009. The loss per share for 2010 was $0.43 on weighted average shares outstanding of 45.6 million as compared to a loss per share of $0.81 for 2009 on weighted average diluted shares outstanding of 45.0 million. The loss in 2010 was primarily related to the loss on our divestiture of oil and gas properties in Mississippi of $25.8 million ($16.8 million after income taxes).

Liquidity and Capital Resources

Funding for our activities has historically been provided by our operating cash flow, debt or equity financings and asset dispositions. Our net cash provided by operating activities in 2011 totaled $284.9 million. Our other primary sources of funds in 2011 included $293.4 million of net proceeds from our senior notes offering, $555.0 million of borrowings under our bank credit facility and $53.4 million of proceeds from sales of marketable securities. In 2010, our net cash flow provided by operating activities totaled $311.7 million. Our other primary source of funds in 2010 was $96.9 million of net proceeds from sales of oil and gas properties and marketable securities and $45.0 million of borrowings under our bank credit facility. In 2009, our net cash flow provided by operating activities from continuing operations totaled $176.3 million. Our other primary source of funds in 2009 was $289.2 million of net proceeds from the issuance of senior notes and $135.0 million of borrowings under our bank credit facility.

Our cash flow from operating activities in 2011 of $284.9 million decreased by $26.8 million from our cash from operating activities of $311.7 million in 2010 mainly due to changes in working capital at the end of 2011. Cash flow from operations excluding changes in working capital accounts of $297.6 million in 2011 increased 35% as compared to $219.7 million in 2010 due to the higher revenues we

received from increased production and higher oil prices. Our cash flow from operating activities from operations in 2010 increased by $135.4 million to $311.7 million as compared to $176.3 million in 2009 primarily due to higher revenues which were mainly due to the higher oil and natural gas prices we realized in 2010.

Our primary need for capital, in addition to funding our ongoing operations, relates to the acquisition, development and exploration of our oil and gas properties and the repayment of our debt. During 2011 our capital expenditures of $1.0 billion increased by $502.0 million as compared to 2010 capital expenditures of $545.7 million due primarily to the $218.7 million spent to acquire proved oil and gas properties and $255.7 million to acquire unproved exploration acreage in 2011. Capital expenditures in 2011 also include $129.5 million spent to complete wells drilled in 2010. In 2010, our capital expenditures of $545.7 million increased by $200.9 million as compared to 2009 capital expenditures of $344.8 million.

Our annual capital expenditure activity is summarized in the following table:

The timing of most of our capital expenditures is discretionary because we have no material long-term capital expenditure commitments except for contracted drilling and completion services. Consequently, we have a significant degree of flexibility to adjust the level of our capital expenditures as circumstances warrant. We currently expect to spend approximately $458.0 million for development and exploration projects in 2012, which will be funded primarily by cash flows from operating activities, proceeds from asset sales and borrowings under our credit facility. Our operating cash flow and, therefore, our capital expenditures are highly dependent on oil and natural gas prices and, in particular, natural gas prices.

We do not have a specific acquisition budget for 2012 because the timing and size of acquisitions are unpredictable. Smaller acquisitions will generally be funded from operating cash flow. With respect to significant acquisitions, we intend to use borrowings under our bank credit facility, or other debt or equity financings to the extent available, to finance such acquisitions. The availability and attractiveness of these sources of financing will depend upon a number of factors, some of which will relate to our financial condition and performance and some of which will be beyond our control, such as prevailing interest rates, oil and natural gas prices and other market conditions. Lack of access to the debt or equity markets due to general economic conditions could impede our ability to complete acquisitions.

We have a $850.0 million bank credit facility with Bank of Montreal, as the administrative agent. The bank credit facility is a five-year revolving credit commitment that matures on November 30, 2015. Indebtedness under the bank credit facility is secured by all of our and our wholly owned subsidiaries’ assets and is guaranteed by all of our wholly owned subsidiaries. The bank credit facility is subject to borrowing base availability, which is redetermined semiannually based on the banks’ estimates of the

49

future net cash flows of our oil and natural gas properties. As of December 31, 2011, the borrowing base was $610.0 million, plus an additional $90.0 million available through December 31, 2012 for a total of $700.0 million, $100.0 million of which was available. The borrowing base may be affected by the performance of our properties and changes in oil and natural gas prices. The determination of the borrowing base is at the sole discretion of the administrative agent and the bank group. Borrowings under the bank credit facility bear interest, based on the utilization of the borrowing base, at our option at either (1) LIBOR plus 1.75% to 4.0% or (2) the base rate (which is the higher of the administrative agent’s prime rate, the federal funds rate plus 0.5% or 30 day LIBOR plus 1.0%) plus 0.75% to 3.0%. A commitment fee of 0.5% is payable on the unused borrowing base. The bank credit facility contains covenants that, among other things, restrict the payment of cash dividends in excess of $50.0 million, limit the amount of consolidated debt that we may incur and limit our ability to make certain loans and investments. The only financial covenants are the maintenance of a ratio of current assets, including the availability under the bank credit facility, to current liabilities and maintenance of a leverage ratio. We were in compliance with these covenants as of December 31, 2011.

We have $300.0 million of 8 ³/8% senior notes outstanding which are due October 15, 2017. Interest is payable semiannually on each October 15 and April 15. We also have $300.0 million of 7 ³/4% senior notes outstanding which are due April 1, 2019. Interest is paid semiannually on each April 1 and October 1. The senior notes are unsecured obligations and are guaranteed by all of our material subsidiaries.

On January 1, 2011, we had $172.0 million in principal amount of 6 ⁷/8% senior notes outstanding due in 2012 (the “2012 Notes”). We redeemed all of the 2012 Notes in 2011 for $172.4 million. The early extinguishment of the 2012 Notes resulted in a loss of $1.1 million which is included in interest expense in the consolidated financial statements. This loss is comprised of the premium paid for the redemption of the 2012 Notes, the costs incurred related to the tender offer, and the write-off of unamortized debt issuance costs related to the 2012 Notes.

We believe that our cash flow from operations and available borrowings under our bank credit facility will be sufficient to fund our operations and future growth as contemplated under our current business plan. However, if our plans or assumptions change or if our assumptions prove to be inaccurate, we may be required to seek additional capital. We cannot provide any assurance that we will be able to obtain such capital, or if such capital is available, that we will be able to obtain it on acceptable terms.

Future interest costs are based upon the effective interest rates of our outstanding senior notes and the December 31, 2011 rate for our bank credit facility.

We have obligations to incur future payments for dismantlement, abandonment and restoration costs of oil and gas properties. These payments are currently estimated to be incurred primarily after 2016. We record a separate liability for the fair value of these asset retirement obligations, which totaled $14.0 million as of December 31, 2011.

Federal Taxation

Our federal income tax returns for the years subsequent to December 31, 2006 remain subject to examination. Our income tax returns in major state income tax jurisdictions remain subject to examination for various periods subsequent to December 31, 2006. We currently believe that our significant filing positions are highly certain and that all of our significant income tax filing positions and deductions would be sustained upon audit or the final resolution would not have a material effect on our consolidated financial statements. Therefore, we have not established any significant reserves for uncertain tax positions. Interest and penalties resulting from audits by tax authorities have been immaterial and are included in the provision for income taxes in the consolidated statements of operations.

At December 31, 2011 we had U.S. federal net operating loss carryforwards of approximately $63.2 million and Louisiana state net operating loss carryforwards of approximately $484.5 million. Utilization of $36.9 million of our U.S. federal net operating loss carryforwards is limited to approximately $1.1 million per year pursuant to a prior change of control of an acquired company and a valuation allowance of $23.0 million has been established for the estimated U.S. federal net operating loss carryforwards that will not be utilized. Realization of the remaining U.S. federal net operating loss carryforwards requires Comstock to generate taxable income within the carryforward period. A valuation allowance of $222.8 million has been established against our Louisiana state net operating loss carryforwards due to the uncertainty of generating taxable income in the state of Louisiana prior to the expiration of the carryforward period.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and use assumptions that can affect the reported amounts of assets, liabilities, revenues or expenses.

Successful efforts accounting.    We are required to select among alternative acceptable accounting policies. There are two generally acceptable methods for accounting for oil and gas producing activities. The full cost method allows the capitalization of all costs associated with finding oil and natural gas reserves, including certain general and administrative expenses. The successful efforts method allows only for the capitalization of costs associated with developing proven oil and natural gas properties as well as exploration costs associated with successful exploration projects. Costs related to exploration that are not successful are expensed when it is determined that commercially productive oil and gas reserves were not found. We have elected to use the successful efforts method to account for our oil and gas activities and we do not capitalize any of our general and administrative expenses.

Oil and natural gas reserve quantities.    The determination of depreciation, depletion and amortization expense is highly dependent on the estimates of the proved oil and natural gas reserves attributable to our properties. The determination of whether impairments should be recognized on our oil

51

and gas properties is also dependent on these estimates, as well as estimates of probable reserves. Reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be precisely measured. The accuracy of any reserve estimate depends on the quality of available data, production history and engineering and geological interpretation and judgment. Because all reserve estimates are to some degree imprecise, the quantities of oil and natural gas that are ultimately recovered, production and operating costs, the amount and timing of future development expenditures and future oil and natural gas prices may all differ materially from those assumed in these estimates. The information regarding present value of the future net cash flows attributable to our proved oil and natural gas reserves are estimates only and should not be construed as the current market value of the estimated oil and natural gas reserves attributable to our properties. Thus, such information includes revisions of certain reserve estimates attributable to proved properties included in the preceding year’s estimates. Such revisions reflect additional information from subsequent activities, production history of the properties involved and any adjustments in the projected economic life of such properties resulting from changes in product prices. Any future downward revisions could adversely affect our financial condition, our borrowing ability, our future prospects and the value of our common stock.

Impairment of oil and gas properties.     We evaluate our properties on a field area basis for potential impairment when circumstances indicate that the carrying value of an asset may not be recoverable. If impairment is indicated based on a comparison of the asset’s carrying value to its undiscounted expected future net cash flows, then it is recognized to the extent that the carrying value exceeds fair value. A significant amount of judgment is involved in performing these evaluations since the results are based on estimated future events. Expected future cash flows are determined using estimated future prices based on market based forward prices applied to projected future production volumes. The projected production volumes are based on the property’s proved and risk adjusted probable oil and natural gas reserve estimates at the end of the period. The estimated future cash flows that we use in our assessment of the need for an impairment are based on market prices for oil and natural gas for the next three years, with a 5% escalation of prices for subsequent years. Prices are not escalated to levels that exceed observed historical market prices. Costs are also assumed to escalate at a rate that is based on our historical experience, currently estimated at 2% per annum. The oil and natural gas prices used for determining asset impairments will generally differ from those used in the standardized measure of discounted future net cash flows because the standardized measure requires the use of the average first day of the month historical price for the year. To the extent that oil and natural gas prices do not increase as anticipated in these assumptions or costs increase at a greater rate than assumed, certain of our evaluated properties which presently have a carrying value of $146.7 million may require impairment in the future. The amount of such impairments would be based on the write down of these properties to their then current estimated fair value. In addition to these properties, other properties may become impaired due to downward revisions in reserve or price estimates or for other reasons.

Asset retirement obligations.     We have obligations to remove tangible equipment and facilities and to restore land at the end of oil and gas production operations. Our removal and restoration obligations are primarily associated with plugging and abandoning wells and removing and disposing of any surface equipment used in production operations. Estimating the future restoration and removal costs is difficult and requires management to make estimates and judgments because most of the removal obligations are many years in the future. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety and public relations considerations.

Stock-based compensation.     We follow the fair value based method in accounting for equity-based compensation. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the award vesting period.

Related Party Transactions

In recent years, we have not entered into any material transactions with our officers or directors apart from the compensation they are provided for their services. We also have not entered into any business transactions with our significant stockholders or any other related parties.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Oil and Natural Gas Prices

Our financial condition, results of operations and capital resources are highly dependent upon the prevailing market prices of oil and natural gas. These commodity prices are subject to wide fluctuations and market uncertainties due to a variety of factors that are beyond our control. Factors influencing oil and natural gas prices include the level of global demand for crude oil, the foreign supply of oil and natural gas, the establishment of and compliance with production quotas by oil exporting countries, weather conditions which determine the demand for natural gas, the price and availability of alternative fuels and overall economic conditions. It is impossible to predict future oil and natural gas prices with any degree of certainty. Sustained weakness in oil and natural gas prices may adversely affect our financial condition and results of operations, and may also reduce the amount of oil and natural gas reserves that we can produce economically. Any reduction in our oil and natural gas reserves, including reductions due to price fluctuations, can have an adverse affect on our ability to obtain capital for our exploration and development activities. Similarly, any improvements in oil and natural gas prices can have a favorable impact on our financial condition, results of operations and capital resources. Based on our oil and natural gas production in 2011, a $1.00 change in the price per barrel of oil would have resulted in a change in our cash flow for such period by approximately $0.8 million and a $1.00 change in the price per Mcf of natural gas would have changed our cash flow by approximately $89.8 million.

We have hedged approximately 60 to 70% of our price risk associated with our expected crude oil sales in 2012. We have entered into oil price swap agreements covering 1.7 million barrels of our expected 2012 oil production which fix the NYMEX West Texas Intermediate (“WTI”) price at $99.46 per barrel. We also have entered into oil price swap agreements for 1.1 million barrels of our expected 2013 production which fix the NYMEX WTI price at $100.33 per barrel. As of December 31, 2011, our outstanding crude oil swap agreements had a fair value of $0.5 million. The change in the fair value of our crude oil swaps that would result from a 10% change in commodities prices at December 31, 2011 would be $13.7 million. Such a change in fair value could be a gain or a loss depending on whether prices increase or decrease.

Interest Rates

At December 31, 2011, we had $1.2 billion of long-term debt. Of this amount, $300.0 million bears interest at a fixed rate of 7 ³/4% and $300.0 million bears interest at 8 ³/8%. The fair market value of our fixed rate debt as of December 31, 2011 was $567.0 million based on the market price of approximately 95% of the face amount. At December 31, 2011, we had $600.0 million outstanding under our bank credit facility, which is subject to variable rates of interest. Borrowings under the bank credit facility bear interest at a fluctuating rate that is tied to LIBOR or the corporate base rate, at our option. Any increase in these interest rates would have an adverse impact on our results of operations and cash flow. Based on borrowings outstanding at December 31, 2011, a 100 basis point change in interest rates would change our annual interest expense on our variable rate debt by approximately $6.0 million. We had no interest rate derivatives outstanding during 2011 or at December 31, 2011.

ITEM 9A.     CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures.     Our Chief Executive Officer and Chief Financial Officer have evaluated, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures are adequate and effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

Changes in internal control over financial reporting.     There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the fourth quarter of 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

The management of Comstock Resources, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting

54

and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles.

As of December 31, 2011, management assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in “Internal Control — Integrated Framework,” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2011, based on those criteria.

Ernst & Young LLP, the independent registered public accounting firm that audited the consolidated financial statements of the Company included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2011. The report, which expresses unqualified opinions on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2011 is included below.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Comstock Resources, Inc.

We have audited Comstock Resources, Inc.’s internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Comstock Resources, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Comstock Resources, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Comstock Resources, Inc. and subsidiaries as of December 31, 2010 and 2011, and the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2011 and our report dated February 27, 2012 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Comstock Resources, Inc.

We have audited the accompanying consolidated balance sheets of Comstock Resources, Inc. and subsidiaries as of December 31, 2010 and 2011, and the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Comstock Resources, Inc. and subsidiaries at December 31, 2010 and 2011, and the consolidated results of their operations and cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Comstock Resources, Inc.’s internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2012 expressed an unqualified opinion thereon.

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)   Summary of Significant Accounting Policies

Accounting policies used by Comstock Resources, Inc. reflect oil and natural gas industry practices and conform to accounting principles generally accepted in the United States of America.

Basis of Presentation and Principles of Consolidation

Comstock Resources, Inc. is engaged in oil and natural gas exploration, development and production, and the acquisition of producing oil and natural gas properties. The Company’s operations are primarily focused in Texas and Louisiana. The consolidated financial statements include the accounts of Comstock Resources, Inc. and its wholly owned or controlled subsidiaries (collectively, “Comstock” or the “Company”). The consolidated financial statements also include the accounts of a variable interest entity where the Company is the primary beneficiary of the arrangements. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company accounts for its undivided interest in oil and gas properties using the proportionate consolidation method, whereby its share of assets, liabilities, revenues and expenses are included in its financial statements.

Reclassifications

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

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. Changes in the future estimated oil and natural gas reserves or the estimated future cash flows attributable to the reserves that are utilized for impairment analysis could have a significant impact on the future results of operations.

Concentration of Credit Risk and Accounts Receivable

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents, accounts receivable and derivative financial instruments. The Company places its cash with high credit quality financial institutions and its derivative financial instruments with financial institutions and other firms that management believes have high credit ratings. Substantially all of the Company’s accounts receivable are due from either purchasers of oil and gas or participants in oil and gas wells for which the Company serves as the operator. Generally, operators of oil and gas wells have the right to offset future revenues against unpaid charges related to operated wells. Oil and gas sales are generally unsecured. The Company has not had any significant credit losses in the past and believes its accounts receivable are fully collectible. Accordingly, no allowance for doubtful accounts has been provided.

Marketable Securities

As of December 31, 2010 and 2011, the Company owned 3,797,069 and 1,806,000 shares, respectively, of Stone Energy Corporation common stock which was reflected in the consolidated balance sheets as marketable securities. As of December 31, 2010 and 2011, the cost basis of the marketable

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

securities was $34.9 million and $16.6 million, respectively. As of December 31, 2010 and 2011, the estimated fair value of the marketable securities was $84.6 million and $47.6 million, respectively, after recognizing unrealized gain after income taxes of $32.3 million and $20.2 million, respectively. The Company does not exert influence over the operating and financial policies of Stone, 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. During 2010 and 2011 the Company sold 1,520,000 and 1,991,000 shares of Stone common stock for proceeds of $30.5 million and $53.4 million, respectively. Comstock realized gains before income taxes of $16.5 million and $35.1 million on these sales during 2010 and 2011, respectively. 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. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary.

Other Current Assets

Other current assets at December 31, 2010 and 2011 consist of the following:

	As of December 31,

	$	4,675	$	3,255

Property and Equipment

The Company follows the successful efforts method of accounting for its oil and natural gas properties. Acquisition costs for proved oil and natural gas properties, costs of drilling and equipping productive wells, and costs of unsuccessful development wells are capitalized and amortized on an equivalent unit-of-production basis over the life of the remaining related oil and gas reserves. Equivalent units are determined by converting oil to natural gas at the ratio of one barrel of oil for six thousand cubic feet of natural gas. This conversion ratio is not based on the price of oil or natural gas, and there may be a significant difference in price between an equivalent volume of oil versus natural gas. Cost centers for amortization purposes are determined on a field area basis. Costs incurred to acquire oil and gas leasehold are capitalized. The estimated future costs of dismantlement, restoration, plugging and abandonment of oil and gas properties and related facilities disposal are capitalized when asset retirement obligations are incurred and amortized as part of depreciation, depletion and amortization expense. The costs of unproved properties which are determined to be productive are transferred to proved oil and gas properties and amortized on an equivalent unit-of-production basis. Exploratory expenses, including geological and geophysical expenses and delay rentals for unevaluated oil and gas properties, are charged

F-9

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

to expense as incurred. Unproved oil and gas properties are periodically assessed and any impairment in value is charged to exploration expense. During 2011 an impairment charge of $9.8 million was recognized in exploration expense related to certain leases that the Company no longer expects to drill on. Exploratory drilling costs are initially capitalized as unproved property but charged to expense if and when the well is determined not to have found commercial quantities of proved oil and gas reserves. Exploratory drilling costs are evaluated within a one-year period after the completion of drilling.

The Company periodically assesses the need for an impairment of the costs capitalized for its oil and gas properties on a property or cost center basis. If impairment is indicated based on undiscounted expected future cash flows attributable to the property, then a provision for impairment is recognized to the extent that net capitalized costs exceed the estimated fair value of the property. The fair value is based upon estimated discounted future cash flows which are derived from Level 3 inputs. Expected future cash flows are determined using estimated future prices based on market based forward prices applied to projected future production volumes. Costs are also projected to escalate at a rate that is based upon the Company’s historical experience. The projected production volumes are based on the property’s proved and risk adjusted probable oil and natural gas reserve estimates at the end of the period. The oil and natural gas prices used for determining asset impairments will generally differ from those used in the standardized measure of discounted future net cash flows because the standardized measure requires the use of an average price based on the first day of each month of the preceding year and is limited to proved reserves. The Company recognized impairment charges related to its oil and gas properties of $0.1 million, $0.2 million and $60.8 million in 2009, 2010, and 2011, respectively.

Other property and equipment consists primarily of gas gathering systems, computer equipment, furniture and fixtures and an airplane which are depreciated over estimated useful lives ranging from three to 31 ¹/2 years on a straight-line basis.

Accrued Expenses

Accrued expenses at December 31, 2010 and 2011 consist of the following:

	As of December 31,

	$	40,490	$	85,502

Reserve for Future Abandonment Costs

The Company’s asset retirement obligations relate to future plugging and abandonment costs of its oil and gas properties and related facilities disposal. The Company records a liability in the period in which an asset retirement obligation is incurred, in an amount equal to the discounted estimated fair value of the obligation that is capitalized. Thereafter, this liability is accreted up to the final retirement cost. Accretion of the discount is included as part of depreciation, depletion and amortization in the accompanying consolidated financial statements.

Other Assets

Other assets primarily consist of deferred costs associated with issuance of the Company’s senior notes and bank credit facility. These costs are amortized over the life of the senior notes and the life of the bank credit facility on a straight-line basis which approximates the amortization that would be calculated using an effective interest rate method.

Stock-based Compensation

The Company follows the fair value based method in accounting for equity-based compensation. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the award vesting period. Excess tax benefits on stock-based compensation are recognized as an increase to additional paid-in capital and as a part of cash flows from financing activities.

Segment Reporting

The Company presently operates in one business segment, the exploration and production of oil and natural gas.

Derivative Instruments and Hedging Activities

The Company accounts for derivative instruments (including certain derivative instruments embedded in other contracts) as either an asset or liability measured at its fair value. Changes in the fair value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met. The Company estimates fair value based on a discounted cash flow model and quotes obtained from the counterparties to the derivative contract. The fair value of derivative contracts that expire in less than one year are recognized as current assets or liabilities. Those that expire in more than one year are recognized as long-term assets or liabilities. Derivative financial instruments that are not accounted for as hedges are adjusted to fair value through income. If the derivative is designated as a cash flow hedge, changes in fair value are recognized in other comprehensive income until the hedged item is recognized in earnings.

Major Purchasers

In 2011 the Company had two purchasers of its oil and natural gas production that accounted for 49% and 14%, respectively, of total oil and gas sales. In 2010 the Company had one purchaser of its oil and natural gas production that accounted for 39% of total oil and gas sales. In 2009 the Company had two purchasers of its oil and natural gas production that accounted for 22% and 11%, respectively, of total

F-11

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

oil and gas sales. The loss of any of these customers would not have a material adverse effect on the Company as there is an available market for its crude oil and natural gas production from other purchasers.

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 December 31, 2010 or 2011. Sales of crude oil and natural gas generally occur at the wellhead. When sales of oil and gas occur at locations other than the wellhead, the Company accounts for costs incurred to transport the production to the delivery point as operating expenses.

General and Administrative Expenses

General and administrative expenses are reported net of reimbursements of overhead costs that are received from working interest owners of the oil and gas properties operated by the Company of $10.2 million, $10.6 million and $10.5 million in 2009, 2010 and 2011, respectively.

Income Taxes

The Company accounts for income taxes using the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as the future tax consequences attributable to the future utilization of existing tax net operating loss and other types of carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that the change in rate is enacted.

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 included in the computation of basic and diluted earnings per share pursuant to the two-class method.

Fair Value Measurements

The Company holds or has held certain items that are required to be measured at fair value. These include cash equivalents held in bank accounts and marketable securities comprised of shares of Stone common stock, and derivative financial instruments in the form of oil or natural gas price swap agreements. 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. A three-level hierarchy is followed for disclosure to show the extent and level of judgment used to estimate fair value measurements:

Level 1 – 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.

Level 2 – Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of the reporting date through correlation with market data,

F-13

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.

Level 3 – Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

The Company’s cash and marketable securities valuation are based on Level 1 measurements. The Company’s oil and natural gas price swap agreements were not traded on a public exchange, and their value was determined utilizing a discounted cash flow model based on inputs that are not readily available in public markets and, according, the valuation of these swap agreements was categorized as a Level 3 measurement.

The following table summarizes financial assets accounted for at fair value as of December 31, 2011:

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.

Cash payments made for interest and income taxes for the years ended December 31, 2009, 2010 and 2011, respectively, were as follows:

	2009			2010			2011

Subsequent Events

Subsequent events were evaluated through the issuance date of these consolidated financial statements.

In January 2012 the Company adopted a plan of disposal for certain of its oil and natural gas properties in South Texas and North Louisiana. Comstock has engaged an advisor to market the properties to a broad group of industry participants. These properties have a net carrying value of $91.7 million and an asset retirement obligation of $0.8 million as of December 31, 2011. The Company expects to reclassify these assets as held for sale in its financial statements in 2012.

(2)   Acquisitions and Dispositions of Oil and Gas Properties

On December 29, 2011, the Company completed an acquisition, from an unrelated party, of oil and gas properties in the Delaware Basin located in Reeves County in West Texas (the “Delaware Basin Acquisition”). Total cash consideration paid was approximately $334.7 million and was funded with borrowings under the Company’s bank credit facility. The Company acquired proved oil and gas reserves of 25.2 million barrels of oil equivalent and leases covering 43,591 net acres. The effective date of the acquisition was November 1, 2011. Concurrent with the Delaware Basin Acquisition, Comstock entered into a transaction structured as a reverse like-kind exchange in accordance with Section 1031 of the Internal Revenue Code. In connection with this reverse like-kind exchange, Comstock assigned the right to acquire ownership in the oil and gas properties that were acquired to a variable interest entity formed by an exchange accommodation titleholder. Comstock operates these properties pursuant to lease and management agreements with that entity, and has a call option which allows the Company to terminate the exchange transaction at any time up and until the expiration date of the exchange. Because the Company is the primary beneficiary of these arrangements, the properties acquired are included in its consolidated balance sheet as of December 29, 2011, and all revenues earned and expenses incurred related to the properties will be included in the Company’s consolidated results of operations during the

F-16

term of the agreements. These agreements will terminate upon the transfer of the acquired properties from the exchange accommodation titleholder to Comstock no later than June 26, 2012, the expiration date for this exchange.

The preliminary purchase price allocation, before final post-closing adjustments which are expected to be finalized during 2012, is as follows:

	(In thousands)
Consideration paid:
Cash	$	334,661
Total consideration paid	$	334,661

Amounts recognized for the preliminary fair value of assets acquired and liabilities assumed were as follows:

Unproved properties		143,751
Asset retirement obligation		(741	)
Liabilities assumed		(10,872	)
Net fair value of properties acquired and liabilities assumed	$	334,661

Comstock considered the Delaware Basin Acquisition a business combination and estimated the fair value of the properties as of December 29, 2011, the acquisition date. To estimate the fair value of the properties, the Company used a net asset value approach. The Company utilized a discounted cash flow model that took into account the following inputs to arrive at estimates of future net cash flows:

• Estimated ultimate recovery of oil and natural gas;

• Estimated future commodity prices based on NYMEX crude oil and natural gas futures prices adjusted for estimated location and quality differentials as well as related transportation costs;

• Estimated future production rates; and

• Estimated timing and amounts of future operating and development costs.

To estimate the fair value of proved properties, the Company discounted the future net cash flows using a market-based rate that the Company determined appropriate at the acquisition date for the various proved reserve categories. To compensate for the inherent risk of estimating and valuing unproved properties, the Company reduced the discounted future net cash flows of the unproved properties by additional risk-weighting factors. Due to the unobservable nature of the inputs, the fair values of the proved and unproved oil and gas properties are considered Level 3 fair value measurements.

On December 30, 2011, the Company acquired oil and gas properties in North Louisiana from a third party for $27.1 million. This acquisition included proved oil and gas reserves of 13 billion cubic feet of natural gas equivalent and leases covering 3,500 net acres. The purchase price was allocated $16.9 million to proved properties and $10.2 million to unproved properties.

The Company has not presented pro forma information for the acquisitions as their impact was not material to the consolidated balance sheet or results of operations for the year ended December 31, 2011. The results of operations from the acquired properties are included in the Company’s consolidated financial statements from the closing dates of December 29, 2011 and December 30, 2011, respectively. Revenue and net income related to the acquired properties for the year ended December 31, 2011 was insignificant.

In December 2010, the Company sold its oil and gas properties in Mississippi to a third party and received net proceeds of $65.3 million. Comstock recognized a loss of $25.8 million on this sale.

Comstock has a $850.0 million bank credit facility with Bank of Montreal, as the administrative agent. The credit facility is a five year revolving credit commitment that matures on November 30, 2015. Indebtedness under the credit facility is secured by substantially all of Comstock’s assets and is guaranteed by all of its wholly owned subsidiaries. The credit facility is subject to borrowing base availability, which is redetermined semiannually based on the banks’ estimates of the Company’s future net cash flows of oil and natural gas properties. The borrowing base may be affected by the performance of Comstock’s properties and changes in oil and natural gas prices. The determination of the borrowing base is at the sole discretion of the administrative agent and the bank group. As of December 31, 2011, the borrowing base was $610.0 million, plus an additional $90.0 million available through December 31, 2012 for a total of $700.0 million, $100.0 million of which was available. Borrowings under the credit facility bear interest, based on the utilization of the borrowing base, at Comstock’s option at either (1) LIBOR plus 1.75% to 4.0% or (2) the base rate (which is the higher of the administrative agent’s prime rate, the federal funds rate plus 0.5% or 30 day LIBOR plus 1.0%) plus 0.75% to 3.0%. A commitment fee of 0.5% is payable annually on the unused borrowing base. The credit facility contains covenants that, among other things, restrict the payment of cash dividends in excess of $50.0 million, limit the amount of consolidated debt that Comstock may incur and limit the Company’s ability to make certain loans and investments. The only financial covenants are the maintenance of a ratio of current assets, including availability under the bank credit facility, to current liabilities and maintenance of a leverage ratio. The Company was in compliance with these covenants as of December 31, 2011.

On March 14, 2011, Comstock issued $300.0 million of senior notes (the “2019 Notes”) pursuant to an underwritten public offering. The 2019 Notes are due on April 1, 2019 and bear interest at 7 ³/4%,

which is payable semiannually on each April 1 and October 1. The 2019 Notes are unsecured obligations of Comstock and are guaranteed by all of the Company’s material subsidiaries. Comstock also has $300.0 million of 8 ³/8% senior notes outstanding which mature on October 15, 2017 (the “2017 Notes”). Interest on the 2017 Notes is payable semiannually on each April 15 and October 15. The 2017 Notes are also unsecured obligations of Comstock and are guaranteed by all of Comstock’s material subsidiaries. Such subsidiary guarantors are 100% owned and all of the guarantees are full and unconditional and joint and several obligations. Comstock controls a variable interest entity that was formed in connection with its reverse like-kind tax exchange and this entity is also a guarantor of the 2017 Notes and the 2019 Notes. As of December 31, 2011, Comstock had no material assets or operations which are independent of its subsidiaries or its consolidated variable interest entity. There are no restrictions on the ability of Comstock to obtain funds from its subsidiaries through dividends or loans.

On January 1, 2011, Comstock had $172.0 million in principal amount of 6 ⁷/8% senior notes outstanding due in 2012 (the “2012 Notes”). Comstock redeemed all of the 2012 Notes in 2011 for $172.4 million. The early extinguishment of the 2012 Notes resulted in a loss of $1.1 million which is included in interest expense in the consolidated financial statements. This loss is comprised of the premium paid for the redemption of the 2012 Notes, the costs incurred related to the tender offer, and the write-off of unamortized debt issuance costs related to the 2012 Notes.

At December 31, 2011, Comstock had the following carryforwards available to reduce future income taxes:

Types of Carryforward	Years of Expiration Carryforward	Amount
		(In thousands)
Net operating loss — U.S. federal	2017 — 2031	$	63,223
Net operating loss — Louisiana	2011 — 2026	$	484,462
Alternative minimum tax credits	Unlimited	$	19,093

Utilization of $36.9 million of the U.S. federal net operating loss carryforwards is limited to approximately $1.1 million per year pursuant to a prior change of control of an acquired company, and a valuation allowance of $23.0 million, with a tax effect of $8.0 million, has been established for the estimated U.S. federal net operating loss carryforwards that will not be utilized. Realization of the remaining U.S. federal net operating loss carryforwards requires Comstock to generate taxable income within the carryforward period. A valuation allowance of $222.8 million, with a tax effect of $11.6 million, has been established against the Louisiana state net operating loss carryforwards due to the uncertainty of generating taxable income in the state of Louisiana prior to the expiration of the carryforward period.

The Company’s federal income tax returns for the years subsequent to December 31, 2006 remain subject to examination. The Company’s income tax returns in major state income tax jurisdictions remain subject to examination for various periods subsequent to December 31, 2006. State tax returns in two state jurisdictions are currently under review. The Company currently believes that resolution of these matters will not have a material impact on its financial statements. The Company currently believes that its significant filing positions are highly certain and that all of its other significant income tax filing positions and deductions would be sustained upon audit or the final resolution would not have a material

effect on the consolidated financial statements. Therefore, the Company has not established any significant reserves for uncertain tax positions. Interest and penalties resulting from audits by tax authorities have been immaterial and are included in the provision for income taxes in the consolidated statements of operations.

(10)    Derivative Financial Instruments and Hedging Activities

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 volumes 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.

In January 2008, Comstock entered into natural gas swaps to fix the price at $8.00 per Mmbtu (at the Houston Ship Channel) for 520,000 Mmbtu’s per month of production for the period February 2008 through December 2009. The Company designated these swaps at their inception as cash flow hedges. Realized gains and losses were included in oil and natural gas sales in the month of production. 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. Changes in fair value resulting from ineffectiveness was recognized currently in oil and natural gas sales as unrealized gains (losses). The Company realized gains of $26.3 million on the natural gas price swaps settled during 2009 which are included in oil and gas sales in the accompanying consolidated statements of operations.

In December 2011, Comstock entered into oil price swap agreements for 1,440,000 barrels of its expected 2012 oil production. The oil price swap agreements fix the NYMEX West Texas Intermediate (“WTI”) oil price at $99.17 per barrel. The Company had no derivative financial instruments outstanding as of December 31, 2010. Subsequent to December 31, 2011, the Company increased the hedged 2012 oil production to 1,710,000 barrels at an average NYMEX WTI oil price of $99.46 per barrel. Comstock also has entered into oil price swap agreements covering 1,080,000 barrels of the Company’s expected 2013 oil production at a NYMEX WTI price of $100.33 per barrel.

End of year		4,894			367,102			2,961			506,809			8,405			550,474

The proved oil and gas reserves utilized in the preparation of the financial statements were estimated by Lee Keeling and Associates, independent petroleum consultants, in accordance with guidelines established by the Securities and Exchange Commission and the Financial Accounting Standards Board, which require that reserve reports be prepared under existing economic and operating conditions with no provision for price and cost escalation except by contractual agreement. All of the Company’s reserves are located onshore in the continental United States of America.

The following table sets forth the standardized measure of discounted future net cash flows relating to proved reserves at December 31, 2010 and 2011:

	2010			2011

Standardized Measure of Discounted Future Net Cash Flows	$	606,136		$	1,113,495

The standardized measure of discounted future net cash flows at the end of 2010 and 2011 was determined based on the simple average of the first of month market prices for oil and natural gas for each year. Prices were $76.31 per barrel of oil and $4.16 per Mcf of natural gas for 2010 and $92.93 per barrel of oil and $4.18 per Mcf of natural gas for 2011. Prices used in determining quantities of oil and natural

gas reserves and future cash inflows from oil and natural gas reserves represent prices received at the Company’s sales point. These prices have been adjusted from posted or index prices for both location and quality differences.

Future development and production costs are computed by estimating the expenditures to be incurred in developing and producing proved oil and gas reserves at the end of the year, based on year end costs and assuming continuation of existing economic conditions. Future income tax expenses are computed by applying the appropriate statutory tax rates to the future pre-tax net cash flows relating to proved reserves, net of the tax basis of the properties involved. The future income tax expenses give effect to permanent differences and tax credits, but do not reflect the impact of future operations.

The following table sets forth the changes in the standardized measure of discounted future net cash flows relating to proved reserves for the years ended December 31, 2009, 2010 and 2011:

RE:       Estimated Reserves and

             Future Net Revenue

             Comstock Resources, Inc.

             Constant Prices and Expenses

Gentlemen:

In accordance with your request, we have prepared an estimate of net reserves and future net revenue to be realized from the interests owned by Comstock Resources, Inc. (Comstock) for 2011 year-end reporting. These interests are in oil and gas properties located in the states of Arkansas, Kansas, Kentucky, Louisiana, New Mexico, Oklahoma, Texas, and Wyoming. Reserves estimated by us reflect all of Comstock’s corporate reserves. The effective date of this estimate is December 31, 2011. It was completed February 3, 2012, and the results are summarized as follows:

	ESTIMATED REMAINING				NET GAS**		FUTURE NET REVENUE
	NET RESERVES				EQUIVALENT				Present Worth
RESERVE	Oil		Gas*				Total		Disc.@10%

* Includes natural gas liquids (NGL) at 3.5 MCF per barrel of NGL.

** Net Gas Equivalent is calculated based on a conversion factor of 6 MCF of gas per barrel of oil.

Note: Totals may not agree with schedules due to computer roundoff.

Future net revenue is the amount, exclusive of state and federal income taxes, which will accrue to Comstock’s interest from continued operation of the properties to depletion. It should not be construed as a fair market or trading value.

No attempt has been made to quantify or otherwise account for any accumulative gas production imbalances that may exist. Neither has an attempt been made to determine whether the wells and facilities are in compliance with various governmental regulations, nor have costs been included in the event they are not.

This report consists of various summaries. Schedule No. 1 presents summary forecasts of annual gross and net production, severance and ad valorem taxes, operating income, and net revenue by reserve type. Schedule No. 2 is a sequential listing of the individual properties based on discounted future net revenue. Schedule No. 3 is a sequential listing of the individual properties based on discounted future net revenue by reserve category. An alphabetical one-line summary by property is presented on Schedule No. 4. A one-line listing of the individual properties, ordered by reserve category, state and project, is presented on Schedule No. 5. A geographical one-line summary by state, project and lease is shown on Schedule No. 6.

CLASSIFICATION OF RESERVES

Reserves assigned to the various leases and/or wells have been classified as either “proved developed” or “proved undeveloped” in accordance with the definitions of the proved reserves as promulgated by the Securities and Exchange Commission (SEC). These are as follows:

Proved Developed Oil and Gas Reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery should be included as “proved developed reserves” only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.

Proved Undeveloped Oil and Gas Reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage shall be limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Under no circumstances should estimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir.

Proved Developed Oil and Gas Reserves attributed to the subject leases have been further classified as “proved developed producing,” “proved developed non-producing” and “proved developed behind-pipe.”

Proved Developed Producing Reserves are those reserves expected to be recovered from currently producing zones under continuation of present operating methods.

Proved Developed Non-Producing Reserves are those reserves expected to be recovered from zones that have been completed and tested but are not yet producing due to situations including, but not limited to, lack of market, minor completion problems that are expected to be corrected, or reserves expected from future stimulation treatments based on analogy to nearby wells.

Proved Developed Behind-Pipe Reserves are those reserves currently behind the pipe in existing wells that are considered proved by virtue of successful testing or production in offsetting wells.

ESTIMATION OF RESERVES

The majority of the subject wells have been producing for a considerable length of time. Reserves attributable to wells with a well-defined production and/or pressure decline trend were based upon extrapolation of that trend to an economic limit and/or abandonment pressure.

Reserves anticipated from new wells were based upon volumetric calculations or analogy with similar properties, which are producing from the same horizons in the respective areas. Structural position, net pay thickness, well productivity, gas/oil ratios, water production, pressures, and other pertinent factors were considered in the estimation of these reserves.

Reserves assigned to behind-pipe zones and undeveloped locations have been estimated based on volumetric calculations and/or analogy with other wells in the area producing from the same horizon.

There are proved undeveloped reserves assigned to locations that will not be developed within five years because company resources are focused on developing the deeper Haynesville zone and deferring development of the shallower Cotton Valley zones in the same area.

FUTURE NET REVENUE

Oil Income

Income from the sale of oil was estimated using the average price received for oil sold from the subject properties the first day of each month during 2011. These prices were provided by the staff of Comstock. The average price, $96.19 per barrel, was held constant throughout the life of each property. Provisions were made for state severance and ad valorem taxes where applicable.

Gas Income

Income from the sale of gas was also estimated using the average price received for gas sold from the subject properties the first day of each month during 2011. These prices were provided by the staff of Comstock. In certain instances, it was necessary to adjust prices to reflect the difference between gas sales volumes and produced volumes. The average price, $4.118 per million cubic feet, was held constant throughout the life of each property. Provisions were also made for state severance and ad valorem taxes where applicable.

Projected produced gas volumes from Double “A” Wells Field wells were reduced to sales volumes based on actual shrinkage data as provided by Comstock.

Operating Expenses

Operating expenses were based upon actual operating costs charged by the respective operators as supplied by the staff of Comstock or were based upon the actual experience of the operators in the respective areas. For leases operated by Comstock, monthly operating costs included lease operating expenses and producing overhead charges. All expenses have been held constant throughout the life of each lease.

Future Expenses and Abandonment Costs

As provided by Comstock, provisions have been made for future expenses required for drilling, recompletion and/or abandonment costs. These costs have been held constant from current estimates.

QUALIFICATIONS OF LEE KEELING AND ASSOCIATES, INC.

Lee Keeling and Associates, Inc. has been offering consulting engineering and geological services to integrated oil companies, independent operators, investors, financial institutions, legal firms, accounting firms and governmental agencies since 1957. Its professional staff is experienced in all productive areas of the United States, Canada, Latin America and many other foreign countries. The firm’s reports are recognized by major financial institutions and used as the basis for oil company mergers, purchases, sales, financing of projects and for registration purposes with financial and regulatory authorities throughout the world.

GENERAL

Information upon which this estimate of net reserves and future net revenue has been based was furnished by the staff of Comstock or was obtained by us from outside sources we consider to be reliable. This information is assumed to be correct. No attempt has been made to verify title or ownership of the subject properties. Interests attributed to wells to be drilled at undeveloped locations are based on current ownership. Leases were not inspected by a representative of this firm, nor were the wells tested under our supervision; however, the performance of the majority of the wells was discussed with employees of Comstock.

This report has been prepared utilizing all methods and procedures regularly used by petroleum engineers to estimate oil and gas reserves for properties of this type and character, and we have used all methods and procedures necessary to prepare this report. The recovery of oil and gas reserves and projection of producing rates are dependent upon many variable factors including prudent operation, compression of gas when needed, market demand, installation of lifting equipment, and remedial work when required. The reserves included in this report have been based upon the assumption that the wells will be operated in a prudent manner under the same conditions existing on the effective date. Actual production results and future well data may yield additional facts, not presently available to us, which may require an adjustment to our estimates. The assumptions, data, methods and procedures used in connection with the preparation of this report are appropriate for the purpose served by this report.

The reserves included in this report are estimates only and should not be construed as being exact quantities. They may or may not be actually recovered and if recovered, the revenues therefrom and the actual costs related thereto could be more or less than the estimated

amounts. As in all aspects of oil and gas estimation, there are uncertainties inherent in the interpretation of engineering data and, therefore, our conclusions necessarily represent only informed professional judgments.

The projection of cash flow has been made assuming constant prices. There is no assurance that prices will not vary. For this reason and those listed in the previous paragraph, the future net cash from the sale of production from the subject properties may vary from the estimates contained in this report.

It should be pointed out that regulatory authorities could, in the future, change the allocation of reserves allowed to be produced from a particular well in any reservoir, thereby altering the material premise upon which our reserve estimates may be based.

The information developed during the course of this investigation, basic data, maps and worksheets showing recovery determinations are available for inspection in our office.

We appreciate this opportunity to be of service to you.

Very truly yours,

/S/ LEE KEELING AND ASSOCIATES, INC.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

(1)   Summary of Significant Accounting Policies

Accounting policies used by Comstock Resources, Inc. reflect oil and natural gas industry practices and conform to accounting principles generally accepted in the United States of America.

Basis of Presentation and Principles of Consolidation

Comstock Resources, Inc. is engaged in oil and natural gas exploration, development and production, and the acquisition of producing oil and natural gas properties. The Company’s operations are primarily focused in Texas and Louisiana. The consolidated financial statements include the accounts of Comstock Resources, Inc. and its wholly owned or controlled subsidiaries (collectively, “Comstock” or the “Company”). The consolidated financial statements also include the accounts of a variable interest entity where the Company is the primary beneficiary of the arrangements. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company accounts for its undivided interest in oil and gas properties using the proportionate consolidation method, whereby its share of assets, liabilities, revenues and expenses are included in its financial statements.

Reclassifications

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

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. Changes in the future estimated oil and natural gas reserves or the estimated future cash flows attributable to the reserves that are utilized for impairment analysis could have a significant impact on the future results of operations.

Concentration of Credit Risk and Accounts Receivable

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents, accounts receivable and derivative financial instruments. The Company places its cash with high credit quality financial institutions and its derivative financial instruments with financial institutions and other firms that management believes have high credit ratings. Substantially all of the Company’s accounts receivable are due from either purchasers of oil and gas or participants in oil and gas wells for which the Company serves as the operator. Generally, operators of oil and gas wells have the right to offset future revenues against unpaid charges related to operated wells. Oil and gas sales are generally unsecured. The Company has not had any significant credit losses in the past and believes its accounts receivable are fully collectible. Accordingly, no allowance for doubtful accounts has been provided.

Marketable Securities

As of December 31, 2010 and 2011, the Company owned 3,797,069 and 1,806,000 shares, respectively, of Stone Energy Corporation common stock which was reflected in the consolidated balance sheets as marketable securities. As of December 31, 2010 and 2011, the cost basis of the marketable securities was $34.9 million and $16.6 million, respectively. As of December 31, 2010 and 2011, the estimated fair value of the marketable securities was $84.6 million and $47.6 million, respectively, after recognizing unrealized gain after income taxes of $32.3 million and $20.2 million, respectively. The Company does not exert influence over the operating and financial policies of Stone, 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. During 2010 and 2011 the Company sold 1,520,000 and 1,991,000 shares of Stone common stock for proceeds of $30.5 million and $53.4 million, respectively. Comstock realized gains before income taxes of $16.5 million and $35.1 million on these sales during 2010 and 2011, respectively. 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. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary.

Other Current Assets

Other current assets at December 31, 2010 and 2011 consist of the following:

	As of December 31,
	2010		2011
	(In thousands)
Pipe inventory	$	1,552	$	2,314
Drilling advances		194		—
Derivative financial instruments		—		459
Prepaid expenses		381		397
Production tax refunds receivable		2,500		—
Other		48		85
	$	4,675	$	3,255

Property and Equipment

The Company follows the successful efforts method of accounting for its oil and natural gas properties. Acquisition costs for proved oil and natural gas properties, costs of drilling and equipping productive wells, and costs of unsuccessful development wells are capitalized and amortized on an equivalent unit-of-production basis over the life of the remaining related oil and gas reserves. Equivalent units are determined by converting oil to natural gas at the ratio of one barrel of oil for six thousand cubic feet of natural gas. This conversion ratio is not based on the price of oil or natural gas, and there may be a significant difference in price between an equivalent volume of oil versus natural gas. Cost centers for amortization purposes are determined on a field area basis. Costs incurred to acquire oil and gas leasehold are capitalized. The estimated future costs of dismantlement, restoration, plugging and abandonment of oil and gas properties and related facilities disposal are capitalized when asset retirement obligations are incurred and amortized as part of depreciation, depletion and amortization expense. The costs of unproved properties which are determined to be productive are transferred to proved oil and gas properties and amortized on an equivalent unit-of-production basis. Exploratory expenses, including geological and geophysical expenses and delay rentals for unevaluated oil and gas properties, are charged to expense as incurred. Unproved oil and gas properties are periodically assessed and any impairment in value is charged to exploration expense. During 2011 an impairment charge of $9.8 million was recognized in exploration expense related to certain leases that the Company no longer expects to drill on. Exploratory drilling costs are initially capitalized as unproved property but charged to expense if and when the well is determined not to have found commercial quantities of proved oil and gas reserves. Exploratory drilling costs are evaluated within a one-year period after the completion of drilling.

The Company periodically assesses the need for an impairment of the costs capitalized for its oil and gas properties on a property or cost center basis. If impairment is indicated based on undiscounted expected future cash flows attributable to the property, then a provision for impairment is recognized to the extent that net capitalized costs exceed the estimated fair value of the property. The fair value is based upon estimated discounted future cash flows which are derived from Level 3 inputs. Expected future cash flows are determined using estimated future prices based on market based forward prices applied to projected future production volumes. Costs are also projected to escalate at a rate that is based upon the Company’s historical experience. The projected production volumes are based on the property’s proved and risk adjusted probable oil and natural gas reserve estimates at the end of the period. The oil and natural gas prices used for determining asset impairments will generally differ from those used in the standardized measure of discounted future net cash flows because the standardized measure requires the use of an average price based on the first day of each month of the preceding year and is limited to proved reserves. The Company recognized impairment charges related to its oil and gas properties of $0.1 million, $0.2 million and $60.8 million in 2009, 2010, and 2011, respectively.

Other property and equipment consists primarily of gas gathering systems, computer equipment, furniture and fixtures and an airplane which are depreciated over estimated useful lives ranging from three to 31 ¹/2 years on a straight-line basis.

Accrued Expenses

Accrued expenses at December 31, 2010 and 2011 consist of the following:

	As of December 31,
	2010		2011
	(In thousands)
Accrued oil and gas property acquisition costs	$	—	$	31,988
Accrued drilling costs		19,040		29,291
Other		21,450		24,223
	$	40,490	$	85,502

Reserve for Future Abandonment Costs

The Company’s asset retirement obligations relate to future plugging and abandonment costs of its oil and gas properties and related facilities disposal. The Company records a liability in the period in which an asset retirement obligation is incurred, in an amount equal to the discounted estimated fair value of the obligation that is capitalized. Thereafter, this liability is accreted up to the final retirement cost. Accretion of the discount is included as part of depreciation, depletion and amortization in the accompanying consolidated financial statements.

The following table summarizes the changes in the Company’s total estimated liability:

	2009			2010			2011
	(In thousands)
Reserve for Future Abandonment Costs at beginning of the year	$	5,480		$	6,561		$	6,674
New wells placed on production and changes in estimates		853			934			6,256
Acquisition liabilities assumed		—			—			741
Liabilities settled and assets disposed of		(86	)		(1,212	)		(56	)
Accretion expense		314			391			382
Reserve for Future Abandonment Costs at end of the year	$	6,561		$	6,674		$	13,997

Other Assets

Other assets primarily consist of deferred costs associated with issuance of the Company’s senior notes and bank credit facility. These costs are amortized over the life of the senior notes and the life of the bank credit facility on a straight-line basis which approximates the amortization that would be calculated using an effective interest rate method.

Stock-based Compensation

The Company follows the fair value based method in accounting for equity-based compensation. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the award vesting period. Excess tax benefits on stock-based compensation are recognized as an increase to additional paid-in capital and as a part of cash flows from financing activities.

Segment Reporting

The Company presently operates in one business segment, the exploration and production of oil and natural gas.

Derivative Instruments and Hedging Activities

The Company accounts for derivative instruments (including certain derivative instruments embedded in other contracts) as either an asset or liability measured at its fair value. Changes in the fair value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met. The Company estimates fair value based on a discounted cash flow model and quotes obtained from the counterparties to the derivative contract. The fair value of derivative contracts that expire in less than one year are recognized as current assets or liabilities. Those that expire in more than one year are recognized as long-term assets or liabilities. Derivative financial instruments that are not accounted for as hedges are adjusted to fair value through income. If the derivative is designated as a cash flow hedge, changes in fair value are recognized in other comprehensive income until the hedged item is recognized in earnings.

Major Purchasers

In 2011 the Company had two purchasers of its oil and natural gas production that accounted for 49% and 14%, respectively, of total oil and gas sales. In 2010 the Company had one purchaser of its oil and natural gas production that accounted for 39% of total oil and gas sales. In 2009 the Company had two purchasers of its oil and natural gas production that accounted for 22% and 11%, respectively, of total oil and gas sales. The loss of any of these customers would not have a material adverse effect on the Company as there is an available market for its crude oil and natural gas production from other purchasers.

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 December 31, 2010 or 2011. Sales of crude oil and natural gas generally occur at the wellhead. When sales of oil and gas occur at locations other than the wellhead, the Company accounts for costs incurred to transport the production to the delivery point as operating expenses.

General and Administrative Expenses

General and administrative expenses are reported net of reimbursements of overhead costs that are received from working interest owners of the oil and gas properties operated by the Company of $10.2 million, $10.6 million and $10.5 million in 2009, 2010 and 2011, respectively.

Income Taxes

The Company accounts for income taxes using the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as the future tax consequences attributable to the future utilization of existing tax net operating loss and other types of carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that the change in rate is enacted.

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 included in the computation of basic and diluted earnings per share pursuant to the two-class method.

Basic and diluted earnings per share for 2009, 2010 and 2011 were determined as follows:

	2009								2010								2011
	Income			Shares		Per Share			Income			Shares		Per Share			Income			Shares		Per Share
	(In thousands except per share data)
Net Loss	$	(36,471	)						$	(19,586	)						$	(33,472	)
Income Allocable to Unvested Stock Grants		—								—								—
Basic Net Loss Attributable to Common Stock	$	(36,471	)		45,004	$	(0.81	)	$	(19,586	)		45,561	$	(0.43	)	$	(33,472	)		45,997	$	(0.73	)

At December 31, 2009, 2010 and 2011, 2,036,450, 2,069,275 and 2,114,520 shares of unvested restricted stock, respectively, 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 included in common stock outstanding were as follows:

	2009		2010		2011
	(In thousands)
Unvested restricted stock		1,583		1,715		1,683

The shares of unvested stock were anti-dilutive to earnings and excluded from weighted average shares used in the computation of earnings per share due to the net loss in each period.

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

	2009		2010		2011
	(In thousands except per share data)
Weighted average anti-dilutive stock options		447		240		215
Weighted average exercise price	$	24.93	$	35.98	$	36.42

All stock options were excluded as anti-dilutive due to the net loss in each period.

Fair Value Measurements

The Company holds or has held certain items that are required to be measured at fair value. These include cash equivalents held in bank accounts and marketable securities comprised of shares of Stone common stock, and derivative financial instruments in the form of oil or natural gas price swap agreements. 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. A three-level hierarchy is followed for disclosure to show the extent and level of judgment used to estimate fair value measurements:

Level 1 – 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.

Level 2 – Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.

Level 3 – Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

The Company’s cash and marketable securities valuation are based on Level 1 measurements. The Company’s oil and natural gas price swap agreements were not traded on a public exchange, and their value was determined utilizing a discounted cash flow model based on inputs that are not readily available in public markets and, according, the valuation of these swap agreements was categorized as a Level 3 measurement.

The following table summarizes financial assets accounted for at fair value as of December 31, 2011:

	Carrying Value Measured at Fair Value at December 31, 2011		Level 1		Level 3
	(In thousands)
Items measured at fair value on a recurring basis:
Cash held in bank accounts	$	8,460	$	8,460	$	—

Derivative financial instruments		459		—		459
Total assets	$	56,561	$	56,102	$	459

The Company had no derivative financial instruments as of December 31, 2010. As of December 31, 2011 the Company had oil price swap agreements for 1,440,000 barrels of oil in 2012 with a fair value of $0.5 million. The Company has recognized a current asset for this amount, and has recognized an unrealized gain of $0.3 million, net of income taxes of $0.2 million, which is included in other comprehensive income.

The following table summarizes the changes in the fair values of derivative financial instruments, which are Level 3 liabilities, for the years ended December 31, 2009, 2010 and 2011:

	(In thousands)
Long-term debt, including current portion	$	513,372	$	518,930	$	1,196,908	$	1,167,000

The fair market value of the Company’s fixed rate debt was based on the market prices as of December 31, 2010 and 2011. The fair value of the floating rate debt outstanding at December 31, 2011 approximated its carrying value.

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.

Cash payments made for interest and income taxes for the years ended December 31, 2009, 2010 and 2011, respectively, were as follows:

	2009			2010			2011
	(In thousands)
Cash Payments:
Interest payments	$	15,827		$	40,467		$	49,109
Income tax payments (refunds)	$	(4,924	)	$	(48,575	)	$	(1,403	)

The Company capitalizes interest on its unevaluated oil and gas property costs during periods when it is conducting exploration activity on this acreage. The Company capitalized interest of $6.6 million, $13.0 million and $13.2 million in 2009, 2010 and 2011, respectively, which reduced interest expense and increased the carrying value of its unevaluated oil and gas properties.

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:

At December 31, 2011, Comstock had the following carryforwards available to reduce future income taxes:

Types of Carryforward	Years of Expiration Carryforward	Amount
		(In thousands)
Net operating loss — U.S. federal	2017 — 2031	$	63,223
Net operating loss — Louisiana	2011 — 2026	$	484,462
Alternative minimum tax credits	Unlimited	$	19,093

Utilization of $36.9 million of the U.S. federal net operating loss carryforwards is limited to approximately $1.1 million per year pursuant to a prior change of control of an acquired company, and a valuation allowance of $23.0 million, with a tax effect of $8.0 million, has been established for the estimated U.S. federal net operating loss carryforwards that will not be utilized. Realization of the remaining U.S. federal net operating loss carryforwards requires Comstock to generate taxable income within the carryforward period. A valuation allowance of $222.8 million, with a tax effect of $11.6 million, has been established against the Louisiana state net operating loss carryforwards due to the uncertainty of generating taxable income in the state of Louisiana prior to the expiration of the carryforward period.

The Company’s federal income tax returns for the years subsequent to December 31, 2006 remain subject to examination. The Company’s income tax returns in major state income tax jurisdictions remain subject to examination for various periods subsequent to December 31, 2006. State tax returns in two state jurisdictions are currently under review. The Company currently believes that resolution of these matters will not have a material impact on its financial statements. The Company currently believes that its significant filing positions are highly certain and that all of its other significant income tax filing positions and deductions would be sustained upon audit or the final resolution would not have a material effect on the consolidated financial statements. Therefore, the Company has not established any significant reserves for uncertain tax positions. Interest and penalties resulting from audits by tax authorities have been immaterial and are included in the provision for income taxes in the consolidated statements of operations.

Derivative Financial Instruments and Hedging Activities [Abstract]

Derivative Financial Instruments and Hedging Activities

(10)    Derivative Financial Instruments and Hedging Activities

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 volumes 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.

In January 2008, Comstock entered into natural gas swaps to fix the price at $8.00 per Mmbtu (at the Houston Ship Channel) for 520,000 Mmbtu’s per month of production for the period February 2008 through December 2009. The Company designated these swaps at their inception as cash flow hedges. Realized gains and losses were included in oil and natural gas sales in the month of production. 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. Changes in fair value resulting from ineffectiveness was recognized currently in oil and natural gas sales as unrealized gains (losses). The Company realized gains of $26.3 million on the natural gas price swaps settled during 2009 which are included in oil and gas sales in the accompanying consolidated statements of operations.

In December 2011, Comstock entered into oil price swap agreements for 1,440,000 barrels of its expected 2012 oil production. The oil price swap agreements fix the NYMEX West Texas Intermediate (“WTI”) oil price at $99.17 per barrel. The Company had no derivative financial instruments outstanding as of December 31, 2010. Subsequent to December 31, 2011, the Company increased the hedged 2012 oil production to 1,710,000 barrels at an average NYMEX WTI oil price of $99.46 per barrel. Comstock also has entered into oil price swap agreements covering 1,080,000 barrels of the Company’s expected 2013 oil production at a NYMEX WTI price of $100.33 per barrel.

Comstock has a $850.0 million bank credit facility with Bank of Montreal, as the administrative agent. The credit facility is a five year revolving credit commitment that matures on November 30, 2015. Indebtedness under the credit facility is secured by substantially all of Comstock’s assets and is guaranteed by all of its wholly owned subsidiaries. The credit facility is subject to borrowing base availability, which is redetermined semiannually based on the banks’ estimates of the Company’s future net cash flows of oil and natural gas properties. The borrowing base may be affected by the performance of Comstock’s properties and changes in oil and natural gas prices. The determination of the borrowing base is at the sole discretion of the administrative agent and the bank group. As of December 31, 2011, the borrowing base was $610.0 million, plus an additional $90.0 million available through December 31, 2012 for a total of $700.0 million, $100.0 million of which was available. Borrowings under the credit facility bear interest, based on the utilization of the borrowing base, at Comstock’s option at either (1) LIBOR plus 1.75% to 4.0% or (2) the base rate (which is the higher of the administrative agent’s prime rate, the federal funds rate plus 0.5% or 30 day LIBOR plus 1.0%) plus 0.75% to 3.0%. A commitment fee of 0.5% is payable annually on the unused borrowing base. The credit facility contains covenants that, among other things, restrict the payment of cash dividends in excess of $50.0 million, limit the amount of consolidated debt that Comstock may incur and limit the Company’s ability to make certain loans and investments. The only financial covenants are the maintenance of a ratio of current assets, including availability under the bank credit facility, to current liabilities and maintenance of a leverage ratio. The Company was in compliance with these covenants as of December 31, 2011.

On March 14, 2011, Comstock issued $300.0 million of senior notes (the “2019 Notes”) pursuant to an underwritten public offering. The 2019 Notes are due on April 1, 2019 and bear interest at 7 ³/4%, which is payable semiannually on each April 1 and October 1. The 2019 Notes are unsecured obligations of Comstock and are guaranteed by all of the Company’s material subsidiaries. Comstock also has $300.0 million of 8 ³/8% senior notes outstanding which mature on October 15, 2017 (the “2017 Notes”). Interest on the 2017 Notes is payable semiannually on each April 15 and October 15. The 2017 Notes are also unsecured obligations of Comstock and are guaranteed by all of Comstock’s material subsidiaries. Such subsidiary guarantors are 100% owned and all of the guarantees are full and unconditional and joint and several obligations. Comstock controls a variable interest entity that was formed in connection with its reverse like-kind tax exchange and this entity is also a guarantor of the 2017 Notes and the 2019 Notes. As of December 31, 2011, Comstock had no material assets or operations which are independent of its subsidiaries or its consolidated variable interest entity. There are no restrictions on the ability of Comstock to obtain funds from its subsidiaries through dividends or loans.

On January 1, 2011, Comstock had $172.0 million in principal amount of 6  ⁷/8% senior notes outstanding due in 2012 (the “2012 Notes”). Comstock redeemed all of the 2012 Notes in 2011 for $172.4 million. The early extinguishment of the 2012 Notes resulted in a loss of $1.1 million which is included in interest expense in the consolidated financial statements. This loss is comprised of the premium paid for the redemption of the 2012 Notes, the costs incurred related to the tender offer, and the write-off of unamortized debt issuance costs related to the 2012 Notes.

Comstock Resources, Inc. is engaged in oil and natural gas exploration, development and production, and the acquisition of producing oil and natural gas properties. The Company’s operations are primarily focused in Texas and Louisiana. The consolidated financial statements include the accounts of Comstock Resources, Inc. and its wholly owned or controlled subsidiaries (collectively, “Comstock” or the “Company”). The consolidated financial statements also include the accounts of a variable interest entity where the Company is the primary beneficiary of the arrangements. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company accounts for its undivided interest in oil and gas properties using the proportionate consolidation method, whereby its share of assets, liabilities, revenues and expenses are included in its financial statements.

Reclassifications

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

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. Changes in the future estimated oil and natural gas reserves or the estimated future cash flows attributable to the reserves that are utilized for impairment analysis could have a significant impact on the future results of operations.

Concentration of Credit Risk and Accounts Receivable

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents, accounts receivable and derivative financial instruments. The Company places its cash with high credit quality financial institutions and its derivative financial instruments with financial institutions and other firms that management believes have high credit ratings. Substantially all of the Company’s accounts receivable are due from either purchasers of oil and gas or participants in oil and gas wells for which the Company serves as the operator. Generally, operators of oil and gas wells have the right to offset future revenues against unpaid charges related to operated wells. Oil and gas sales are generally unsecured. The Company has not had any significant credit losses in the past and believes its accounts receivable are fully collectible. Accordingly, no allowance for doubtful accounts has been provided.

Marketable Securities

As of December 31, 2010 and 2011, the Company owned 3,797,069 and 1,806,000 shares, respectively, of Stone Energy Corporation common stock which was reflected in the consolidated balance sheets as marketable securities. As of December 31, 2010 and 2011, the cost basis of the marketable securities was $34.9 million and $16.6 million, respectively. As of December 31, 2010 and 2011, the estimated fair value of the marketable securities was $84.6 million and $47.6 million, respectively, after recognizing unrealized gain after income taxes of $32.3 million and $20.2 million, respectively. The Company does not exert influence over the operating and financial policies of Stone, 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. During 2010 and 2011 the Company sold 1,520,000 and 1,991,000 shares of Stone common stock for proceeds of $30.5 million and $53.4 million, respectively. Comstock realized gains before income taxes of $16.5 million and $35.1 million on these sales during 2010 and 2011, respectively. 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. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary.

Other Current Assets

Other current assets at December 31, 2010 and 2011 consist of the following:

	As of December 31,
	2010		2011
	(In thousands)
Pipe inventory	$	1,552	$	2,314
Drilling advances		194		—
Derivative financial instruments		—		459
Prepaid expenses		381		397
Production tax refunds receivable		2,500		—
Other		48		85
	$	4,675	$	3,255

Property and Equipment

The Company follows the successful efforts method of accounting for its oil and natural gas properties. Acquisition costs for proved oil and natural gas properties, costs of drilling and equipping productive wells, and costs of unsuccessful development wells are capitalized and amortized on an equivalent unit-of-production basis over the life of the remaining related oil and gas reserves. Equivalent units are determined by converting oil to natural gas at the ratio of one barrel of oil for six thousand cubic feet of natural gas. This conversion ratio is not based on the price of oil or natural gas, and there may be a significant difference in price between an equivalent volume of oil versus natural gas. Cost centers for amortization purposes are determined on a field area basis. Costs incurred to acquire oil and gas leasehold are capitalized. The estimated future costs of dismantlement, restoration, plugging and abandonment of oil and gas properties and related facilities disposal are capitalized when asset retirement obligations are incurred and amortized as part of depreciation, depletion and amortization expense. The costs of unproved properties which are determined to be productive are transferred to proved oil and gas properties and amortized on an equivalent unit-of-production basis. Exploratory expenses, including geological and geophysical expenses and delay rentals for unevaluated oil and gas properties, are charged to expense as incurred. Unproved oil and gas properties are periodically assessed and any impairment in value is charged to exploration expense. During 2011 an impairment charge of $9.8 million was recognized in exploration expense related to certain leases that the Company no longer expects to drill on. Exploratory drilling costs are initially capitalized as unproved property but charged to expense if and when the well is determined not to have found commercial quantities of proved oil and gas reserves. Exploratory drilling costs are evaluated within a one-year period after the completion of drilling.

The Company periodically assesses the need for an impairment of the costs capitalized for its oil and gas properties on a property or cost center basis. If impairment is indicated based on undiscounted expected future cash flows attributable to the property, then a provision for impairment is recognized to the extent that net capitalized costs exceed the estimated fair value of the property. The fair value is based upon estimated discounted future cash flows which are derived from Level 3 inputs. Expected future cash flows are determined using estimated future prices based on market based forward prices applied to projected future production volumes. Costs are also projected to escalate at a rate that is based upon the Company’s historical experience. The projected production volumes are based on the property’s proved and risk adjusted probable oil and natural gas reserve estimates at the end of the period. The oil and natural gas prices used for determining asset impairments will generally differ from those used in the standardized measure of discounted future net cash flows because the standardized measure requires the use of an average price based on the first day of each month of the preceding year and is limited to proved reserves. The Company recognized impairment charges related to its oil and gas properties of $0.1 million, $0.2 million and $60.8 million in 2009, 2010, and 2011, respectively.

Other property and equipment consists primarily of gas gathering systems, computer equipment, furniture and fixtures and an airplane which are depreciated over estimated useful lives ranging from three to 31 ¹/2 years on a straight-line basis.

Accrued Expenses

Accrued expenses at December 31, 2010 and 2011 consist of the following:

	As of December 31,
	2010		2011
	(In thousands)
Accrued oil and gas property acquisition costs	$	—	$	31,988
Accrued drilling costs		19,040		29,291
Other		21,450		24,223
	$	40,490	$	85,502

Reserve for Future Abandonment Costs

The Company’s asset retirement obligations relate to future plugging and abandonment costs of its oil and gas properties and related facilities disposal. The Company records a liability in the period in which an asset retirement obligation is incurred, in an amount equal to the discounted estimated fair value of the obligation that is capitalized. Thereafter, this liability is accreted up to the final retirement cost. Accretion of the discount is included as part of depreciation, depletion and amortization in the accompanying consolidated financial statements.

The following table summarizes the changes in the Company’s total estimated liability:

	2009			2010			2011
	(In thousands)
Reserve for Future Abandonment Costs at beginning of the year	$	5,480		$	6,561		$	6,674
New wells placed on production and changes in estimates		853			934			6,256
Acquisition liabilities assumed		—			—			741
Liabilities settled and assets disposed of		(86	)		(1,212	)		(56	)
Accretion expense		314			391			382
Reserve for Future Abandonment Costs at end of the year	$	6,561		$	6,674		$	13,997

Other Assets

Other assets primarily consist of deferred costs associated with issuance of the Company’s senior notes and bank credit facility. These costs are amortized over the life of the senior notes and the life of the bank credit facility on a straight-line basis which approximates the amortization that would be calculated using an effective interest rate method.

Stock-based Compensation

The Company follows the fair value based method in accounting for equity-based compensation. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the award vesting period. Excess tax benefits on stock-based compensation are recognized as an increase to additional paid-in capital and as a part of cash flows from financing activities.

Segment Reporting

The Company presently operates in one business segment, the exploration and production of oil and natural gas.

Derivative Instruments and Hedging Activities

The Company accounts for derivative instruments (including certain derivative instruments embedded in other contracts) as either an asset or liability measured at its fair value. Changes in the fair value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met. The Company estimates fair value based on a discounted cash flow model and quotes obtained from the counterparties to the derivative contract. The fair value of derivative contracts that expire in less than one year are recognized as current assets or liabilities. Those that expire in more than one year are recognized as long-term assets or liabilities. Derivative financial instruments that are not accounted for as hedges are adjusted to fair value through income. If the derivative is designated as a cash flow hedge, changes in fair value are recognized in other comprehensive income until the hedged item is recognized in earnings.

Major Purchasers

In 2011 the Company had two purchasers of its oil and natural gas production that accounted for 49% and 14%, respectively, of total oil and gas sales. In 2010 the Company had one purchaser of its oil and natural gas production that accounted for 39% of total oil and gas sales. In 2009 the Company had two purchasers of its oil and natural gas production that accounted for 22% and 11%, respectively, of total oil and gas sales. The loss of any of these customers would not have a material adverse effect on the Company as there is an available market for its crude oil and natural gas production from other purchasers.

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 December 31, 2010 or 2011. Sales of crude oil and natural gas generally occur at the wellhead. When sales of oil and gas occur at locations other than the wellhead, the Company accounts for costs incurred to transport the production to the delivery point as operating expenses.

General and Administrative Expenses

General and administrative expenses are reported net of reimbursements of overhead costs that are received from working interest owners of the oil and gas properties operated by the Company of $10.2 million, $10.6 million and $10.5 million in 2009, 2010 and 2011, respectively.

Income Taxes

The Company accounts for income taxes using the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as the future tax consequences attributable to the future utilization of existing tax net operating loss and other types of carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that the change in rate is enacted.

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 included in the computation of basic and diluted earnings per share pursuant to the two-class method.

Basic and diluted earnings per share for 2009, 2010 and 2011 were determined as follows:

	2009								2010								2011
	Income			Shares		Per Share			Income			Shares		Per Share			Income			Shares		Per Share
	(In thousands except per share data)
Net Loss	$	(36,471	)						$	(19,586	)						$	(33,472	)

At December 31, 2009, 2010 and 2011, 2,036,450, 2,069,275 and 2,114,520 shares of unvested restricted stock, respectively, 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 included in common stock outstanding were as follows:

	2009		2010		2011
	(In thousands)
Unvested restricted stock		1,583		1,715		1,683

The shares of unvested stock were anti-dilutive to earnings and excluded from weighted average shares used in the computation of earnings per share due to the net loss in each period.

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

	2009		2010		2011
	(In thousands except per share data)
Weighted average anti-dilutive stock options		447		240		215
Weighted average exercise price	$	24.93	$	35.98	$	36.42

All stock options were excluded as anti-dilutive due to the net loss in each period.

Fair Value Measurements

The Company holds or has held certain items that are required to be measured at fair value. These include cash equivalents held in bank accounts and marketable securities comprised of shares of Stone common stock, and derivative financial instruments in the form of oil or natural gas price swap agreements. 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. A three-level hierarchy is followed for disclosure to show the extent and level of judgment used to estimate fair value measurements:

Level 1 – 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.

Level 2 – Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.

Level 3 – Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

The Company’s cash and marketable securities valuation are based on Level 1 measurements. The Company’s oil and natural gas price swap agreements were not traded on a public exchange, and their value was determined utilizing a discounted cash flow model based on inputs that are not readily available in public markets and, according, the valuation of these swap agreements was categorized as a Level 3 measurement.

The following table summarizes financial assets accounted for at fair value as of December 31, 2011:

	Carrying Value Measured at Fair Value at December 31, 2011		Level 1		Level 3
	(In thousands)

Total assets	$	56,561	$	56,102	$	459

The Company had no derivative financial instruments as of December 31, 2010. As of December 31, 2011 the Company had oil price swap agreements for 1,440,000 barrels of oil in 2012 with a fair value of $0.5 million. The Company has recognized a current asset for this amount, and has recognized an unrealized gain of $0.3 million, net of income taxes of $0.2 million, which is included in other comprehensive income.

The following table summarizes the changes in the fair values of derivative financial instruments, which are Level 3 liabilities, for the years ended December 31, 2009, 2010 and 2011:

The fair market value of the Company’s fixed rate debt was based on the market prices as of December 31, 2010 and 2011. The fair value of the floating rate debt outstanding at December 31, 2011 approximated its carrying value.

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.

Cash payments made for interest and income taxes for the years ended December 31, 2009, 2010 and 2011, respectively, were as follows:

	2009			2010			2011
	(In thousands)
Cash Payments:
Interest payments	$	15,827		$	40,467		$	49,109
Income tax payments (refunds)	$	(4,924	)	$	(48,575	)	$	(1,403	)

The Company capitalizes interest on its unevaluated oil and gas property costs during periods when it is conducting exploration activity on this acreage. The Company capitalized interest of $6.6 million, $13.0 million and $13.2 million in 2009, 2010 and 2011, respectively, which reduced interest expense and increased the carrying value of its unevaluated oil and gas properties.

Subsequent Events

Subsequent events were evaluated through the issuance date of these consolidated financial statements.

In January 2012 the Company adopted a plan of disposal for certain of its oil and natural gas properties in South Texas and North Louisiana. Comstock has engaged an advisor to market the properties to a broad group of industry participants. These properties have a net carrying value of $91.7 million and an asset retirement obligation of $0.8 million as of December 31, 2011. The Company expects to reclassify these assets as held for sale in its financial statements in 2012.

Acquisitions and Dispositions of Oil and Gas Properties

(2)   Acquisitions and Dispositions of Oil and Gas Properties

On December 29, 2011, the Company completed an acquisition, from an unrelated party, of oil and gas properties in the Delaware Basin located in Reeves County in West Texas (the “Delaware Basin Acquisition”). Total cash consideration paid was approximately $334.7 million and was funded with borrowings under the Company’s bank credit facility. The Company acquired proved oil and gas reserves of 25.2 million barrels of oil equivalent and leases covering 43,591 net acres. The effective date of the acquisition was November 1, 2011. Concurrent with the Delaware Basin Acquisition, Comstock entered into a transaction structured as a reverse like-kind exchange in accordance with Section 1031 of the Internal Revenue Code. In connection with this reverse like-kind exchange, Comstock assigned the right to acquire ownership in the oil and gas properties that were acquired to a variable interest entity formed by an exchange accommodation titleholder. Comstock operates these properties pursuant to lease and management agreements with that entity, and has a call option which allows the Company to terminate the exchange transaction at any time up and until the expiration date of the exchange. Because the Company is the primary beneficiary of these arrangements, the properties acquired are included in its consolidated balance sheet as of December 29, 2011, and all revenues earned and expenses incurred related to the properties will be included in the Company’s consolidated results of operations during the term of the agreements. These agreements will terminate upon the transfer of the acquired properties from the exchange accommodation titleholder to Comstock no later than June 26, 2012, the expiration date for this exchange.

The preliminary purchase price allocation, before final post-closing adjustments which are expected to be finalized during 2012, is as follows:

Comstock considered the Delaware Basin Acquisition a business combination and estimated the fair value of the properties as of December 29, 2011, the acquisition date. To estimate the fair value of the properties, the Company used a net asset value approach. The Company utilized a discounted cash flow model that took into account the following inputs to arrive at estimates of future net cash flows:

• Estimated ultimate recovery of oil and natural gas;

• Estimated future commodity prices based on NYMEX crude oil and natural gas futures prices adjusted for estimated location and quality differentials as well as related transportation costs;

• Estimated future production rates; and

• Estimated timing and amounts of future operating and development costs.

To estimate the fair value of proved properties, the Company discounted the future net cash flows using a market-based rate that the Company determined appropriate at the acquisition date for the various proved reserve categories. To compensate for the inherent risk of estimating and valuing unproved properties, the Company reduced the discounted future net cash flows of the unproved properties by additional risk-weighting factors. Due to the unobservable nature of the inputs, the fair values of the proved and unproved oil and gas properties are considered Level 3 fair value measurements.

On December 30, 2011, the Company acquired oil and gas properties in North Louisiana from a third party for $27.1 million. This acquisition included proved oil and gas reserves of 13 billion cubic feet of natural gas equivalent and leases covering 3,500 net acres. The purchase price was allocated $16.9 million to proved properties and $10.2 million to unproved properties.

The Company has not presented pro forma information for the acquisitions as their impact was not material to the consolidated balance sheet or results of operations for the year ended December 31, 2011. The results of operations from the acquired properties are included in the Company’s consolidated financial statements from the closing dates of December 29, 2011 and December 30, 2011, respectively. Revenue and net income related to the acquired properties for the year ended December 31, 2011 was insignificant.

In December 2010, the Company sold its oil and gas properties in Mississippi to a third party and received net proceeds of $65.3 million. Comstock recognized a loss of $25.8 million on this sale.

The proved oil and gas reserves utilized in the preparation of the financial statements were estimated by Lee Keeling and Associates, independent petroleum consultants, in accordance with guidelines established by the Securities and Exchange Commission and the Financial Accounting Standards Board, which require that reserve reports be prepared under existing economic and operating conditions with no provision for price and cost escalation except by contractual agreement. All of the Company’s reserves are located onshore in the continental United States of America.

The following table sets forth the standardized measure of discounted future net cash flows relating to proved reserves at December 31, 2010 and 2011:

	2010			2011
	(In thousands)
Cash Flows Relating to Proved Reserves:
Future Cash Flows	$	4,584,382		$	7,656,654
Future Costs:
Production		(1,625,133	)		(2,259,147	)
Development and Abandonment		(1,350,391	)		(2,174,656	)
Future Income Taxes		(386,919	)		(843,266	)
Future Net Cash Flows		1,221,939			2,379,585
10% Discount Factor		(615,803	)		(1,266,090	)
Standardized Measure of Discounted Future Net Cash Flows	$	606,136		$	1,113,495

The standardized measure of discounted future net cash flows at the end of 2010 and 2011 was determined based on the simple average of the first of month market prices for oil and natural gas for each year. Prices were $76.31 per barrel of oil and $4.16 per Mcf of natural gas for 2010 and $92.93 per barrel of oil and $4.18 per Mcf of natural gas for 2011. Prices used in determining quantities of oil and natural gas reserves and future cash inflows from oil and natural gas reserves represent prices received at the Company’s sales point. These prices have been adjusted from posted or index prices for both location and quality differences.

Future development and production costs are computed by estimating the expenditures to be incurred in developing and producing proved oil and gas reserves at the end of the year, based on year end costs and assuming continuation of existing economic conditions. Future income tax expenses are computed by applying the appropriate statutory tax rates to the future pre-tax net cash flows relating to proved reserves, net of the tax basis of the properties involved. The future income tax expenses give effect to permanent differences and tax credits, but do not reflect the impact of future operations.

The following table sets forth the changes in the standardized measure of discounted future net cash flows relating to proved reserves for the years ended December 31, 2009, 2010 and 2011:

	2009			2010			2011
