## To Our Stockholders:

Over three years ago we redirected our focus away from growing our oil production back to our Haynesville/Bossier shale properties in North Louisiana. Our plan was to bring the enhanced completion procedures that had evolved in the oil shale plays and in the Northeast natural gas plays back to the Haynesville shale. We believed that longer lateral lengths and high intensity hydraulic fracturing techniques could more than double the production rates and ultimate recoveries of Haynesville shale wells. During the last three years we have drilled 50 Haynesville/Bossier wells, expanded our acreage footprint in the play and substantially increased our prospect inventory. The results achieved by our Haynesville drilling program have exceeded our expectations and we have continued to get stronger each year with higher production and cash flow generated by our Haynesville drilling program.



Against a backdrop of a challenging industry we accomplished many of our goals in 2017. Our primary goal was to grow our EBITDAX or earnings before interest, taxes, depreciation, depletion, amortization, exploration expense and other noncash expenses to support our debt level. We made great progress toward this goal in 2017. It all starts with production. The Haynesville shale wells we drilled were up to the challenge as they drove a 46% growth in our natural gas production, pro forma for divestitures we made in 2016. We finished strong in the fourth quarter where natural gas production was up 90% over the fourth quarter of 2016. The higher natural gas production caused our 2017 sales to increase by 49% and our EBITDAX increased by 103% over 2016. Cash flow from operations for the year grew to $112 million from a deficit of $8 million in 2016.

Our Haynesville drilling program turned in consistently strong results as we enhanced our completion design and achieved 36% higher initial production rates. In 2017 we drilled 30 successful wells which had an average per well IP rate of 25 MMcf per day. The drilling program allowed us to grow our proved reserve base by 27% and achieve a very low finding cost of 54 cents per Mcfe.




The joint venture we have with USG has allowed us to continue to grow our inventory of Haynesville and Bossier shale locations in 2017 which sit at over 800 today. The first two wells we put on line on some of the new acreage generated by the joint venture look to be outstanding wells with initial production rates of 27 MMcf per day.

We are very focused on improving our balance sheet and are working hard to position the Company to be able to refinance our expensive debt in 2018. Our plans are still to refinance all of our secured notes with a combination of proceeds from the sale of our Eagle Ford properties, a new credit facility, new bonds and some equity.

## 2017 Financial Results

We reported a net loss of $111 million, or $7.61 per share, for 2017 primarily due to the interest expense on our debt. Resumption of our drilling program in late 2016 allowed us to grow our natural gas production by 37% over 2016 (46% pro forma for properties sold in 2016). Our overall production on an Mcf equivalent basis increased by 28% from 2016. In 2017 our realized natural gas price increased by 25% to $2.84 per Mcf and our oil price of $49.02 per barrel increased by 28% from 2016. Oil and gas sales increased 45% to $255 million and EBITDAX improved to $184 million. Our costs were also lower in 2017. Our lifting costs were down 11% and our depreciation, depletion, and amortization (“DD&A”) expense improved by 13%. The lower producing costs reflect our continued shift toward drilling our lower cost Haynesville shale properties versus our higher cost oil projects. Over the last three years, the growth in our Haynesville production caused our lifting costs to improve to $0.77 per Mcfe as compared to $1.48 per Mcfe in 2014. Our DD&A per Mcfe produced has come down dramatically to $1.55 per Mcfe as compared to $5.74 in 2014.







## 2017 Drilling Program

The highlight of 2017 was the successful results from our Haynesville shale drilling program and the growth we had in proved oil and natural gas reserves. In 2017 we replaced our production by 387% and grew proved reserves by 27%. We added 292 Bcfe of new proved oil and natural gas reserves primarily related to our Haynesville shale properties. In addition, we experienced 41 Bcfe in upward revisions primarily related to improved prices and the performance of our Haynesville shale wells which were drilled in 2016 and 2017. Our drilling activities in 2017 allowed us to grow our proved oil and natural gas reserves from 916 Bcfe at the end of 2015 to 1.2 Tcfe at the end of 2017. We divested of 8 Bcfe in 2017 with the sale of some of our conventional natural gas properties. The 2017 proved reserves include 60.7 net proved undeveloped locations reflecting our increased drilling budget for 2018 and
future years. With an inventory of over 800 operated drilling locations, we still have many more to include in the future.



We spent $178.8 million on development activities in 2017. The substantial growth in proved oil and natural gas reserves combined with our capital spending in 2017 resulted in achieved finding costs of approximately 54¢ per Mcfe in 2017. We drilled 30 wells (15.7 net) in 2017; 22 (14.4 net) of the wells were Haynesville shale wells and seven wells (1.3 net) were Bossier shale wells. Sixteen (12.8 net) of the wells drilled in 2017 have been completed and we completed six (3.0 net) Haynesville shale wells that were drilled in 2016. The average initial production rate of the wells we completed in 2017 was 25 MMcf per day.




## Outlook for 2018

Our high return Haynesville shale assets continue to provide us the means to profitably grow our production and cash flow in 2018. Our enhanced completion design has transformed the Haynesville shale into one of North America's highest return natural gas basins and our acreage position gives us over 800 future drilling locations. We expect our 2018 natural gas production to grow 30% based on our planned drilling activity. Our
already low cost structure should continue to improve with further growth in our Haynesville shale production. In 2017 we were able to reduce our lifting costs per Mcfe by 31% and our DD&A per Mcfe has improved by 32% as compared to 2016. Our Balance sheet will continue to improve as we grow our cash flow and EBITDAX. The potential sale of our Eagle Ford shale assets combined with growth in EBITDAX should support our efforts to refinance our secured debt in 2018.

The directors and management of Comstock want to thank the stockholders for their continued support.

## 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.

“BOE” means one barrel of oil 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.

“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.

“MMBOE” means one million barrels of oil equivalent.

“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.



“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.

“Proved developed reserves” means reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

“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 includes 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 by contractual arrangements.

“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 are limited to those drilling locations offsetting productive wells that are reasonably certain of production when drilled or where it can be demonstrated with certainty that there is continuity of production from the existing productive formation.

“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.

“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.

“SEC” means the United States Securities and Exchange Commission.

“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 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 under the symbol “CRK”.

Our oil and gas operations are primarily concentrated in Texas and Louisiana. Our oil and natural gas properties are estimated to have proved reserves of 1,162 Bcfe with a standardized measure of discounted future net cash flows of $881.5 million as of December 31, 2017. Our proved oil and natural gas reserve base is 96% natural gas and 4% oil and was 41% developed as of December 31, 2017.

Our proved reserves at December 31, 2017 and our 2017 average daily production are summarized below:

<table><tr><td rowspan="2"></td><td colspan="4">Proved Reserves at December 31, 2017</td><td colspan="4">2017 Average Daily Production</td></tr><tr><td>Oil (MMBbls)</td><td>Natural Gas (Bcf)</td><td>Total (Bcfe)</td><td>% of Total</td><td>Oil (MBbls/d)</td><td>Natural Gas (MMcf/d)</td><td>Total (MMcfe/d)</td><td>% of Total</td></tr><tr><td>East Texas / North Louisiana</td><td>0.3</td><td>1,103.0</td><td>1,105.0</td><td>95.1%</td><td>0.1</td><td>196.1</td><td>197.0</td><td>90.7%</td></tr><tr><td>Other Regions</td><td>0.2</td><td>3.5</td><td>4.1</td><td>0.3%</td><td>0.1</td><td>1.5</td><td>1.9</td><td>0.9%</td></tr><tr><td></td><td>0.5</td><td>1,106.5</td><td>1,109.1</td><td>95.4%</td><td>0.2</td><td>197.6</td><td>198.9</td><td>91.6%</td></tr><tr><td>South Texas \( ^{(1)} \)</td><td>7.1</td><td>10.5</td><td>53.2</td><td>4.6%</td><td>2.4</td><td>3.8</td><td>18.2</td><td>8.4%</td></tr><tr><td>Total</td><td>7.6</td><td>1,117.0</td><td>1,162.3</td><td>100.0%</td><td>2.6</td><td>201.4</td><td>217.1</td><td>100.0%</td></tr></table>

## Strengths

High Quality Properties. Our operations are principally focused in East Texas/North Louisiana. Our properties have an average reserve life of approximately 15 years and have extensive development and exploration potential. Our properties in the East Texas/North Louisiana region, which are primarily prospective for natural gas, include 87,945 acres (68,310 net to us) in the Haynesville or Bossier shale formations. Advances in drilling and completion technology have allowed us to increase the reserves recovered through longer horizontal lateral length and substantially larger well stimulation. As a result of the improved economic returns that we achieved with our Haynesville shale natural gas wells, and continued low oil prices, our 2017 drilling activity primarily targeted natural gas in the Haynesville shale. Our South Texas region, which consists of our Eagleville field, includes 25,540 acres (18,670 net to us) located in the oil window of the Eagle Ford shale. These properties were classified as held for sale as of December 31, 2017. There can be no assurances that we will be able to consummate the sale of these properties. We also have 34,544 acres (32,898 net to us) in Mississippi and Louisiana that are prospective for oil development in the Tuscaloosa Marine shale. We currently have no plans to develop the Tuscaloosa Marine shale properties prior to the expiration of the leases.

Successful Drilling Program. We spent $178.8 million on development activities in 2017, of which $164.5 million was for drilling activities and the remainder was for leasehold and other developmental costs. We drilled 30 wells (15.7 net to us) and completed 25 wells (16.3 net to us). Primarily all of our 2017 capital expenditures were directed towards natural gas projects. Our natural gas drilling program in 2017 resulted in an increase in our natural gas production by 37% over 2016 and contributed to the 27% growth we had in our natural gas reserves from 2016.



Efficient Operator. We operated 98% of our proved reserve base as of December 31, 2017. As the operator, we are better able to control operating costs, the timing and plans for 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.

## Business Strategy

Grow Natural Gas Reserves and Production. We conduct exploration and development activities with the goal to grow our reserve base and to replace production each year. In 2017, we focused on our Haynesville shale properties in North Louisiana as these properties provide us the highest returns within our opportunity set. We deferred further development of our oil and other natural gas properties given low oil and natural gas prices.

Our Haynesville shale properties were the primary focus of our drilling activity in 2017. We have 87,945 acres (68,310 net to us) in East Texas and North Louisiana with Haynesville shale natural gas potential. We initiated a drilling program in the Haynesville shale in 2015 based on a new well design that significantly enhanced the economics of these wells. We have drilled and completed a total of 35 operated wells (30.3 net to us) targeting the Haynesville or Bossier shale since 2014. These wells had an average per well initial production rate of 25 MMcf per day. We currently expect to drill 31 additional wells targeting the Haynesville and Bossier shale in 2018.

During 2017, we entered agreements to jointly develop certain acreage prospective for the Haynesville shale in Louisiana and Texas with USG Properties Haynesville, LLC (“USG”). As of December 31, 2017, USG had acquired approximately 6,300 net acres prospective for Haynesville shale development for the joint development program primarily in Caddo Parish, Louisiana. We operate wells drilled on USG’s acreage and have the right to acquire a 25% working interest in the acreage by reimbursing USG for the attributable acreage costs of the wells being drilled. Our working interest increases to 40% starting with the 13 \( ^{th} \)  well drilled. USG is also participating in four wells being drilled in our Bossier shale acreage in Sabine Parish, Louisiana and in a Haynesville shale drilling program on approximately 5,700 acres of our acreage in Harrison County, Texas. Under the terms of the participation agreements for Sabine Parish and Harrison County acreage owned by us, we will receive between 1.1 million and 1.4 million, respectively, for 50% of our interest for each location for acreage and infrastructure related to each well location, with 400,000 of that amount being paid only if each well meets or exceeds established production targets. We also receive 80,000 for each well drilled as consideration for our services managing the joint drilling program in addition to customary operating fees for each well drilled except for the four Bossier shale wells. We plan to continue to acquire additional acreage in coordination with USG for the joint development venture.

We have 25,540 acres (18,670 net to us) in South Texas prospective for oil in the Eagle Ford shale. Our Eagleville field includes 191 producing wells that we drilled from 2010 through 2016. These properties were classified as held for sale at December 31, 2017 as we are marketing these properties for sale.

We own 34,544 acres (32,898 net to us) in Louisiana and Mississippi which are prospective for oil in the Tuscaloosa Marine shale. We are not currently anticipating any drilling activity on this acreage.

Enhance Liquidity and Reduce Leverage. We substantially reduced our capital spending in 2015 and shut down our drilling program during parts of 2016. During 2015 and 2016, we retired $236.8 million in principal amount of our senior notes in exchange for cash of $46.1 million and the issuance of 2.8 million shares of our common stock. These repurchases reduced our annual interest



expense by $20.6 million. In September 2016 we completed a debt exchange transaction with the holders of approximately 98% of our outstanding senior notes, which significantly reduced our cash interest payments until 2019 and 2020 and further increased our liquidity through the addition of a $75.0 million payment-in-kind toggle interest feature that is part of our new 10% senior secured notes.

Exploit Existing Reserves. We seek to maximize the value of our oil and natural gas properties by increasing production and recoverable reserves through development drilling and workover, recompletion and exploitation activities. We utilize advanced industry technology, including horizontal drilling, enhanced logging and steering tools, and formation stimulation techniques. In 2018 we plan to restimulate five of our existing Haynesville shale horizontal wells. If successful we have approximately 117 operated and 58 non-operated older producing natural gas shale wells which could be restimulated in the future.

Maintain Flexible Capital Expenditure Budget. The timing of most of our capital expenditures is discretionary because we have limited our exposure to longer-term capital expenditure commitments. 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 three operated drilling rigs under contract for 2018 and currently plan to drill up to 31 wells in 2018. We do not have any contractual requirements to drill any wells and could reduce the number of wells drilled in 2018 based on industry conditions.

## East Texas/North Louisiana Region

Approximately 95%, or 1,105.0 Bcfe of our proved reserves, are located in East Texas and North Louisiana, where we own interests in 872 producing wells (558.1 net to us) in 23 field areas. We operate 625 of these wells. The largest of our fields in this region are the Logansport, Toledo Bend, Waskom, Beckville and Blocker fields. Production from this region averaged 196 MMcf of natural gas per day and 145 barrels of oil per day or 197 MMcfe per day during 2017. Most of the reserves in this



area produce from the upper Jurassic aged Haynesville shale, Bossier shale or Cotton Valley formations and the Cretaceous aged Travis Peak/Hosston formation. We spent $163.8 million drilling 30 wells (15.7 net to us) and $11.3 million on other development and leasehold costs in this region in 2017. We currently plan to spend approximately $150.0 million in 2018 to drill 31 Haynesville shale natural gas wells and to complete an additional 14 (2.8 net to us) Haynesville or Bossier shale wells we drilled in 2017.

## Logansport

The Logansport field located in DeSoto Parish, Louisiana primarily produces from the Haynesville and Bossier shale formations at a depth of 11,100 to 11,500 feet and from multiple sands in the Cotton Valley and Hosston formations at an average depth of 8,000 feet. Our proved reserves of 869.5 Bcfe in the Logansport field represent approximately 75% of our proved reserves. We own interests in 253 wells (181.6 net to us) and operate 196 of these wells in this field. Most of our drilling activities have been focused on our Logansport field where we drilled 16 wells (12.9 net to us) in 2017. We plan to drill ten wells in Logansport in 2018 targeting the Haynesville shale formation.

## Toledo Bend

The Toledo Bend field, located in DeSoto and Sabine parishes in Louisiana, is productive in the Haynesville shale from 11,400 to 11,800 feet and in the Bossier shale from 10,880 to 11,300 feet. Our proved reserves of 111.2 Bcfe in the Toledo Bend field represent approximately 10% of our reserves. We own interests in 78 producing wells (41.1 net to us) and operate 43 of these wells in this field. We drilled seven wells (1.3 net to us) in the Toledo Bend field in 2017. In 2018, we plan to drill three horizontal well targeting the Bossier shale in Toledo Bend.

## Waskom

The Waskom field, located in Harrison and Panola counties in Texas and Caddo parish in Louisiana, represents approximately 7% (84.2 Bcfe) of our proved reserves. We own interests in 52 wells (32.7 net to us) and operate 39 wells in this field. The Waskom field produces from the Cotton Valley formation at depths ranging from 9,000 to 10,000 feet and from the Haynesville shale formation at depths of 10,800 to 10,900 feet. In 2017 we added 8,300 net acres in the Waskom field through leasing or in connection with our joint development venture with USG Properties Haynesville, LLC. We drilled six wells (1.5 net to us) in the Waskom field in 2017. In 2018 we plan to drill 18 horizontal wells (5.6 net to us) targeting the Haynesville shale in the Waskom field.

## Beckville

The Beckville field, located in Panola and Rusk counties, Texas, has estimated proved reserves of 24.8 Bcfe which represents approximately 2% of our proved reserves. We operate 182 wells in this field and own interests in 68 additional wells for a total of 250 wells (152.4 net to us). The Beckville field produces primarily from the Cotton Valley formation at depths ranging from 9,000 to 10,000 feet. The field is also prospective for future Haynesville shale development.

## Blocker

Our proved reserves of 6.0 Bcfe in the Blocker field located in Harrison County, Texas represent approximately 1% of our proved reserves. We own interests in 68 wells (63.0 net to us) and operate 63 of these wells. Most of this production is from the Cotton Valley formation between 8,600 and 10,150 feet and the Haynesville shale formation between 11,100 and 11,450 feet.



## Other Regions

Less than 1%, or 4.0 Bcfe, of our proved reserves are in other regions, primarily in New Mexico and the Mid-Continent region. We own interests in 246 producing wells (30.2 net to us) in nine fields within these regions. Net daily production from our other regions during 2017 totaled 2 MMcf of natural gas and 60 barrels of oil or 2 MMcfe per day.

## South Texas Region

Approximately 5% (53.2 Bcfe) of our proved reserves are located in South Texas, where we own interests in 191 producing wells (132.9 net to us) in our Eagleville field. Net daily production rates from this region averaged 2,399 barrels of oil and 4 MMcf of natural gas per day during 2017. We have 25,540 acres (18,670 net to us) in McMullen, Atascosa, Frio, La Salle, Karnes and Wilson Counties which comprise our Eagleville field. The Eagle Ford shale is found between 7,500 feet and 11,500 feet across our acreage position. Our proved reserves in this field are estimated to be 8.9 MMBOE (53.2 Bcfe) (80% oil) and represent 5% of our total proved reserves. These properties were classified as held for sale as of December 31, 2017 as we are actively marketing them for sale.

## Oil and Natural Gas Reserves

The following table sets forth our estimated proved oil and natural gas reserves as of December 31, 2017:

<table><tr><td></td><td>Oil (MBbls)</td><td>Natural Gas (MMcf)</td><td>Total (MMcfe)</td></tr><tr><td>Proved Developed:</td><td></td><td></td><td></td></tr><tr><td>Producing</td><td>7,259</td><td>370,306</td><td>413,859</td></tr><tr><td>Non-producing</td><td>293</td><td>65,808</td><td>67,569</td></tr><tr><td>Total Proved Developed</td><td>7,552</td><td>436,114</td><td>481,428</td></tr><tr><td>Proved Undeveloped</td><td>—</td><td>680,842</td><td>680,842</td></tr><tr><td>Total Proved</td><td>7,552</td><td>1,116,956</td><td>1,162,270</td></tr><tr><td>Proved developed reserves of assets held for sale</td><td>7,116</td><td>10,484</td><td>53,178</td></tr></table>

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

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 electrical logs, radioactivity logs, core analyses, geologic maps and available production data, seismic data and well test data.

There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves. Oil and natural gas 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 is a function of the quality of available data and of engineering and geological interpretation and judgment. Results of drilling, testing and production subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserve estimates are often different from the quantities of oil and natural gas that are ultimately recovered.

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

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2015</td><td>2016</td><td>2017</td><td></td></tr><tr><td>Oil Price - /Bbl</td><td>$46.19</td><td>$38.24</td><td>$ 49.02</td><td></td></tr><tr><td>Natural Gas Price - /Mcf</td><td>$ 2.30</td><td>$ 2.28</td><td>$ 2.84</td><td></td></tr><tr><td>Lifting Costs - /Mcfe</td><td>$ 1.35</td><td>$ 1.10</td><td>$ 0.77</td><td></td></tr></table>

Prices used in determining quantities of oil and natural gas reserves and future cash inflows from oil and natural gas reserves represent the average first of the month prices received at the point of sale for the last twelve months. These prices have been adjusted from posted prices for both location and quality differences. The oil and natural gas prices used for reserves estimation were as follows:

<table><tr><td>Year</td><td>Oil Price (per Bbl)</td><td>Natural Gas Price (per Mcf)</td></tr><tr><td>2015</td><td>$46.88</td><td>$2.34</td></tr><tr><td>2016</td><td>$37.62</td><td>$2.29</td></tr><tr><td>2017</td><td>$48.71</td><td>$2.88</td></tr></table>

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 connection with estimating proved undeveloped reserves for our reserve report, reserves on undrilled acreage were limited to those that are reasonably certain of production when drilled where we can verify the continuity of the reservoir. We only include wells in our proved undeveloped reserves that we currently plan to drill and in which we have adequate capital resources to enable us to drill them. Using empirical evidence, we utilize control points and sample sizes to show continuity in the reservoir. We reflect changes to undeveloped reserves that occur in the same field as revisions to the extent that proved undeveloped locations are revised due to changes in future development plans, including changes to proposed lateral lengths, development spacing and timing of development.

As of December 31, 2017, our proved undeveloped reserves were comprised of 680.8 Bcf of natural gas. All of our proved undeveloped reserves were associated with our Haynesville and Bossier shale properties where our 2017 drilling program was focused. Our natural gas proved undeveloped reserves



increased by 129.9 Bcf during 2017. This increase was primarily related to the reserve additions which totaled 238.7 Bcf of natural gas, which were comprised of 220.1 Bcf of new undeveloped locations resulting from our successful Haynesville and Bossier shale drilling program and expanded future drilling plans and 18.6 Bcf of upward performance revisions attributable to our Haynesville and Bossier shale undeveloped reserves added in prior years. The reserve additions were partially offset by 103.5 Bcf of reserves converted to developed reserves. Eleven of the Haynesville shale wells we drilled in 2017 resulted in conversions of proved undeveloped reserves to proved developed producing reserves at December 31, 2017.

As of December 31, 2016, our proved undeveloped reserves were comprised of 550.9 Bcf of natural gas. All of our proved undeveloped reserves were associated with our Haynesville and Bossier shale properties where our drilling program in 2016 was focused. Our natural gas proved undeveloped reserves increased by 292.5 Bcf during 2016. This increase was primarily related to the reserve additions and performance related revisions which totaled 347.8 Bcf of natural gas which were comprised of 253.6 Bcf of new undeveloped locations resulting from our successful Haynesville and Bossier shale drilling program and expanded future drilling plans and 94.2 Bcf of upward performance revisions attributable to our Haynesville and Bossier shale undeveloped reserves added in prior years. The reserve additions were partially offset by 55.3 Bcf of reserves converted to developed reserves. Five of the Haynesville shale wells we drilled in 2016 resulted in conversions of proved undeveloped reserves to proved developed producing reserves at December 31, 2016.

We incurred approximately $93.4 million during 2017 in development costs related to proved undeveloped reserves. Our estimated future capital costs to develop proved undeveloped reserves as of December 31, 2017 of $617.3 million increased by $190.0 million from our estimated future capital costs of $427.3 million as of December 31, 2016. This increase is primarily attributable to the inclusion of 32 additional proved undeveloped locations at December 31, 2017.

We incurred approximately $38.0 million during 2016 in development costs related to proved undeveloped reserves in our Haynesville and Bossier shale properties. Our estimated future capital costs to develop proved undeveloped reserves as of December 31, 2016 of $427.3 million increased by $157.3 million from our estimated future capital costs of $270.0 million as of December 31, 2015. This increase was primarily attributable to the inclusion of 32 additional proved undeveloped locations at December 31, 2016.

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 Reservoir Engineering Department, comprised of qualified petroleum engineers and technical support staff, works with our operating, accounting, land and marketing departments in order to accumulate the information required for the reserves estimation process. Our Vice President of Reservoir Engineering is the primary person in charge of overseeing our reserve estimates and our Reservoir Engineering Department. He has a B.S. Degree and a Masters Degree in Petroleum Engineering, is a Registered Professional Engineer and has over forty years of experience in various technical roles within the oil and gas industry. 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.

We did not provide estimates of total proved oil and natural gas reserves during the three year period ended December 31, 2017 to any federal authority or agency, other than the SEC.

In 2018 to the date of this report, we have drilled five wells (1.6 net to us) and we have seven wells (3.3 net to us) currently in the process of being drilled.

## Producing Well Summary

The following table sets forth the gross and net producing oil and natural gas wells in which we owned an interest at December 31, 2017:

<table><tr><td rowspan="2"></td><td colspan="2">Oil</td><td colspan="2">Natural Gas</td></tr><tr><td>Gross</td><td>Net</td><td>Gross</td><td>Net</td></tr><tr><td>Louisiana</td><td>15</td><td>4.7</td><td>425</td><td>257.6</td></tr><tr><td>Mississippi</td><td>2</td><td>1.0</td><td>—</td><td>—</td></tr><tr><td>New Mexico</td><td>1</td><td>—</td><td>90</td><td>13.9</td></tr><tr><td>Oklahoma</td><td>6</td><td>0.5</td><td>100</td><td>9.2</td></tr><tr><td>Texas</td><td>202</td><td>135.0</td><td>442</td><td>297.4</td></tr><tr><td>Wyoming</td><td>—</td><td>—</td><td>26</td><td>1.9</td></tr><tr><td>Total</td><td>226</td><td>141.2</td><td>1,083</td><td>580.0</td></tr><tr><td>Producing wells included in assets held for sale</td><td>190</td><td>131.9</td><td>1</td><td>1.0</td></tr></table>

We operate 810 of the 1,309 producing wells presented in the above table. As of December 31, 2017, we did not own an interest in any wells containing multiple completions, which means that a well is producing from more than one completed zone.



## Acreage

The following table summarizes our developed and undeveloped leasehold acreage at December 31, 2017, 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.

<table><tr><td rowspan="2"></td><td colspan="2">Developed</td><td colspan="2">Undeveloped</td></tr><tr><td>Gross</td><td>Net</td><td>Gross</td><td>Net</td></tr><tr><td>Louisiana</td><td>91,380</td><td>60,881</td><td>12,719</td><td>8,724</td></tr><tr><td>Mississippi</td><td>2,016</td><td>1,944</td><td>30,997</td><td>29,475</td></tr><tr><td>New Mexico</td><td>12,757</td><td>2,740</td><td>—</td><td>—</td></tr><tr><td>Oklahoma</td><td>26,080</td><td>3,382</td><td>—</td><td>—</td></tr><tr><td>Texas</td><td>72,879</td><td>45,151</td><td>6,157</td><td>4,296</td></tr><tr><td>Wyoming</td><td>13,440</td><td>927</td><td>—</td><td>—</td></tr><tr><td>Total</td><td>218,552</td><td>115,025</td><td>49,873</td><td>42,495</td></tr><tr><td>Acreage included in assets held for sale</td><td>21,998</td><td>16,315</td><td>3,542</td><td>2,355</td></tr></table>

Of our total undeveloped acres, 32,528 gross acres (30,953 net) are in the Tuscaloosa Marine shale within the states of Louisiana and Mississippi.

Our undeveloped acreage expires as follows:

<table><tr><td>Expires in 2018</td><td>80%</td></tr><tr><td>Expires in 2019</td><td>2%</td></tr><tr><td>Expires in 2020</td><td>4%</td></tr><tr><td>Thereafter</td><td>14%</td></tr><tr><td></td><td>100%</td></tr></table>

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 secured notes and our bank credit facility. As is customary in the oil and natural 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.

## Markets and Customers

The market for our production of oil and natural gas 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 with other industries in supplying the energy and fuel requirements of industrial, commercial and individual consumers.

Our oil production is currently 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 42% of our 2017 natural gas sales were priced utilizing first of the month index prices and approximately 58% were priced utilizing daily spot prices. BP Energy Company and its subsidiaries, Shell Oil Company and its subsidiaries, CIMA Energy and EOG Resources accounted for 34%, 17%, 16% and 15%, respectively, of our total 2017 sales. The loss of any 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.

We have entered into longer term marketing arrangements to ensure that we have adequate transportation to get our natural gas production in North Louisiana 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 entered into certain agreements with a major natural gas marketing company to provide us with firm transportation for 10,000 MMBtu per day for our North Louisiana natural gas production on the long-haul pipelines. These agreements expire in 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, 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.

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 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 2012 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. Environmental laws and regulations have been subject to frequent 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. The Trump Administration and Congress have made some changes and are expected to make additional changes to laws, regulations, and policies applicable to us. Executive Order 13783 directs federal agencies to review actions that potentially burden the development or use of domestically produced energy resources, and as a result, more regulatory changes are expected. Those changes may be favorable, but we are unable to predict the scope, timing, or impacts of such changes. There are also costs associated with responding to changing regulations and policies, whether such regulations are more or less stringent. 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.

Certain oil and gas wastes may also contain naturally occurring radioactive materials (“NORM”), which is regulated by the federal Occupational Safety and Health Administration and state agencies. These regulations require certain worker protections and waste handling and disposal procedures. We believe our operations comply in all material respects with these worker protection and waste handling and disposal requirements.

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. On April 17, 2012, the U. S. Environmental Protection Agency or “EPA” promulgated new emission standards for the oil and gas industry. These rules require a nearly 95 percent reduction in volatile organic compounds (“VOCs”) emitted from hydraulically fractured gas wells by January 1, 2015. This significant reduction in emissions is to be accomplished primarily through the use of “green completions” (i.e., capturing natural gas that currently escapes to the air). These rules also have notification and reporting requirements. In 2014, EPA revised the emission requirements for storage tanks emitting certain levels of VOCs requiring a 95% reduction of VOC emissions by April 15, 2014 and April 15, 2015 (depending upon the date of construction of the storage tank). In 2016, EPA finalized regulations that required further reductions specifically regarding methane emissions; however, in 2017, EPA announced that it is proposing to stay certain of these requirements for certain periods of time. Issues related to the proposed stay are subject to public comment and court review. If implemented as previously finalized, the set of rules allows EPA to aggregate emissions sources within a quarter mile of each other, thus potentially requiring emission reductions further downstream, including equipment in the natural gas transmission segment of the industry. There are costs associated with following the status and impacts of these changes, and implementing any changes as they become effective. 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 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.

The Federal Safe Drinking Water Act of 1974, as amended, requires EPA to develop minimum federal requirements for Underground Injection Control (“UIC”) programs and other safeguards to protect public health by preventing injection wells from contaminating underground sources of drinking water. The UIC program does not regulate wells that are solely used for production. However, EPA has authority to regulate hydraulic fracturing when diesel fuels are used in fluids or propping agents. In February 2014, EPA issued new guidance on when UIC permitting requirements apply to fracking fluids containing diesel. We believe that our operations comply in all material respects with the requirements of the Federal Safe Drinking Water Act and similar state statutes. We believe the requirements are not any more burdensome to us than to other similarly situated companies involved in oil and natural gas exploration and production activities.

State and federal regulatory agencies recently have focused on a possible connection between the hydraulic fracturing related activities and the increased occurrence of seismic activity. When caused by human activity, such events are called induced seismicity. In a few instances, operators of injection wells in the vicinity of seismic events have been ordered to reduce injection volumes or suspend operations. Some state regulatory agencies, including those in Colorado, Ohio, Oklahoma, and Texas, have modified their regulations to account for induced seismicity. Regulatory agencies at all levels are continuing to study the possible linkage between oil and gas activity and induced seismicity. A 2012 report published by the National Academy of Sciences concluded that only a very small fraction of the tens of thousands of injection wells have been suspected to be, or have been, the likely cause of induced seismicity; and a 2015 report by researchers at the University of Texas has suggested that the link between seismic activity and wastewater disposal may vary by region. In 2015, the United States Geological Survey identified eight states, including Texas, with areas of increased rates of induced seismicity that could be attributed to fluid injection or oil and gas extraction. More recently, in March 2016, the United States Geological Survey identified six states with the most significant hazards from induced seismicity, including Texas, Colorado, Oklahoma, Kansas, New Mexico, and Arkansas. In addition, a number of lawsuits have been filed, most recently in Oklahoma, alleging that disposal well operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. Also, the EPA has agreed to determine whether rules are needed to govern the disposal of wastewater from oil and gas development in order to address the potential for induced seismicity from wastewater injection. These developments could result in additional regulation and restrictions on the use of injection wells and hydraulic fracturing.

In December 2016, the EPA finalized its report on the potential impacts of hydraulic fracturing on drinking water resources, which concluded that hydraulic fracturing activities could impact drinking water resources under some circumstances. Other governmental agencies, including the U.S. Department



of Energy, have evaluated or are evaluating various other aspects of hydraulic fracturing. These ongoing or proposed studies have the potential to impact the likelihood or scope of future legislation or regulation.

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. Administrative policies with respect to such laws are also changing, and we incur costs to follow such changes and comply as changes become effective.

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 2012, 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 2012, with the first annual reports of those emissions due on September 28, 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 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. These greenhouse gas reporting rules were amended on October 22, 2015 to expand the number of sources and operations that are subject to these rules, and again on November 18, 2016 to provide less burdensome reporting requirements. We have determined that these reporting requirements apply to us and we believe we have met all of the EPA required reporting deadlines and strive to ensure accurate and consistent emissions data reporting. It is possible that these requirements may be loosened or otherwise changed in the future. Other EPA actions with respect to the reduction of greenhouse gases (such as EPA’s Greenhouse Gas Endangerment Finding, and EPA’s Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule) and various state actions have or could impose mandatory reductions in greenhouse gas emissions. We are unable to predict at this time how much the cost of compliance with any legislation or regulation of greenhouse gas emissions will be in future periods.

The U.S. has not passed legislation to expressly address GHGs; however, in recent years the EPA moved ahead with its efforts to regulate GHG emissions from certain sources by rule. Beyond requiring measurement and reporting of GHGs as discussed above, 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. States in which we operate may also require permits and reductions in GHG emissions. Additionally, the EPA published a set of final rules in 2016 that require reductions in VOC and methane generation from new sources, and EPA has announced plans to issue rules regulating existing sources. However, these rules have been challenged in court, and in 2017, the EPA took steps to institute a two-year delay in implementing the rules. Similarly, the Bureau of Land Management announced plans to suspend and revise a 2016 rule relating to methane venting, flaring, and leaks from oil and gas production on public lands. Since all of our oil and natural gas production is in the United States, 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 oil and natural gas we produce. In addition, efforts have been made and continue to be made in the international community toward the adoption of international treaties or protocols that would address global climate change issues. Most recently in 2015, the United States participated in the United Nations Conference on Climate Change, which led to the creation of the Paris Agreement. The Paris Agreement requires ratifying countries to review and “represent a progression” in the ambitions of their nationally determined contributions, which set GHG emission reduction goals, every five years. The United States signed the Paris Agreement on April 22, 2016; however, the Trump Administration has stated that it intends to withdraw from the Paris Agreement. The Agreement allows for the U.S. to formally announce its intention to withdraw in November 2019 with the withdrawal effective in November 2020. Considering the extended timeline for this action, impacts to our operations are uncertain; however, we expect that the impacts to our operations will not be materially different from other similarly situated companies involved in oil and natural gas exploration and production activities.

In 2010 the Bureau of Land Management began implementation of a proposed oil and gas leasing reform that would increase environmental review requirements and was expected to have the effect of reducing the amount of new federal lands made available for lease, increasing the competition for and cost of available parcels. Further, in June 2016, the Bureau of Land Management cancelled certain oil and gas leases in areas identified to be closed for leasing based on Clean Air Act requirements. The lease cancellations have been challenged in court, and under the Trump Administration, BLM has announced that it intends to make changes to speed up the permitting process. Additionally, the Bureau of Land Management has formally proposed to rescind a rule the Bureau adopted in 2015 concerning hydraulic fracturing on federal land. The rule would have required increased well integrity testing, increased requirements for the managing of fluids, and the disclosure of chemicals used in fracturing. The rule never went into effect due to legal challenges. Due to the ongoing regulatory and legal uncertainty, we



cannot predict what effect these changes will have on our operations, though the changes may be advantageous. We expect that the impacts to our operations will be similar to other similarly situated companies involved in oil and natural gas exploration and production activities.

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.

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. It is also possible that certain states may increase regulatory activity in response to changing federal regulations or policies.

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.

An extended period of depressed oil and natural gas prices will adversely affect our business, financial condition, cash flow, liquidity, results of operations and our ability to meet our capital expenditure obligations and financial commitments.

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. Oil and natural gas prices declined substantially starting in mid-2014 and, while improving in late



2016, remained relatively low thereafter. During 2017, commodity prices fluctuated significantly, with the settlement price for West Texas Intermediate (“WTI”) crude oil ranging from a high of approximately $60.42 per barrel to a low of approximately $42.53 per barrel and settlement prices for Henry Hub natural gas ranging from a high of approximately $3.42 per Mcf to a low of approximately $2.56 per Mcf. Oil and natural gas price volatility has continued into 2018 and, through February 26, 2018, the WTI settlement price of crude oil had a low of approximately $59.19 per barrel, and the Henry Hub settlement price of natural gas had a low of approximately $2.55 per Mcf.

The prices we receive for our oil and natural gas production are subject to wide fluctuations and depend on numerous factors beyond our control, including the following:

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

• weather conditions;

• the price and quantity of imports of 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.

Lower oil and natural gas 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.

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

We had $1.2 billion principal amount of debt as of December 31, 2017.

Our outstanding debt has important consequences, including, without limitation:

• a portion of our cash flow from operations is required to make debt service payments, although under the terms of our outstanding notes we may, subject to certain conditions, issue additional notes in lieu of making cash interest payments;

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

• our debt limits 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.

Because we have, subject to certain conditions, the ability to pay the interest on our outstanding notes by issuing additional notes, we are likely to incur substantial additional indebtedness over the terms of our outstanding notes. 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 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 debt agreements contain a number of significant covenants. These covenants 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.

Our failure to comply with any of these covenants could cause a default under our bank credit facility and the respective indentures governing our outstanding notes. 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.

Issuances of our common stock in connection with the conversion of our convertible notes would cause substantial dilution, which could materially affect the trading price of our common stock and earnings per share.

As part of the debt exchange transaction we completed in September 2016, as of December 31, 2017 we have $477.9 million of notes that are convertible into shares of our common stock outstanding. As a result, substantial amounts of our common stock may be issued in the future. If all outstanding convertible notes were converted at December 31, 2017, they would represent 72% of our outstanding shares. The future issuances of shares from the conversion of the notes could result in substantial decreases to our stock price and earnings per share.

Our access to capital markets may be limited in the future.

Adverse changes in the financial and credit markets could negatively impact our ability to grow production and reserves and meet our future obligations. In addition, the continuation of the current low oil and natural gas price environment, or further declines of oil and natural gas prices, will affect our ability to obtain financing for acquisitions and drilling activities and could result in a reduction in drilling activity which results in the loss of acreage through lease expirations, both of which could negatively affect our ability to replace reserves.

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 that we will have adequate capital resources to conduct acquisition and drilling activities or 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.

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.

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

Our success depends 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.

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 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.

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.

If oil and natural gas prices decline further or remain low for an extended period of time, we may be required to further 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 recognized impairments that totaled $801.3 million, $27.1 million and $44.0 million during 2015, 2016 and 2017, respectively, which reduced the carrying value of our oil and natural gas properties. We may incur additional 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.

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, 2017, 59% of our total proved reserves were undeveloped and 6% 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.

Some of our undeveloped leasehold acreage is subject to leases that will expire unless production is established on units containing the acreage.

Leases on oil and gas properties normally have a term of three to five years and will expire unless, prior to expiration of the lease term, production in paying quantities is established. If the leases expire and we are unable to renew them, we will lose the right to develop the related properties. Our drilling plans for these areas are subject to change based upon various factors, including drilling results, commodity prices, the availability and cost of capital, drilling and production costs, availability of drilling services and equipment, gathering system and pipeline transportation constraints and regulatory approvals.

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. More recently we have been focused on acquiring acreage for our drilling program. 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 Texas and Louisiana, we may pursue acquisitions or properties located in other geographic areas.

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 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 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.

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 are substantially dependent on the availability of water. Restrictions on our ability to obtain water may have an adverse effect on our financial condition, results of operations and cash flows.

Water is an essential component of both the drilling and hydraulic fracturing processes. Historically, we have been able to purchase water from various sources for use in our operations. If we are unable to obtain water to use in our operations from local sources, we may be unable to economically produce oil and natural gas, which could have an adverse effect on our financial condition, results of operations and cash flows.

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 and/or remedial obligations; and

• the imposition of injunctive relief.

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 GHGs or 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.

Our hedging transactions could result in financial losses or could reduce our income. To the extent we have hedged a significant portion of our expected production and actual production is lower than we expected or the costs of goods and services increase, our profitability would be adversely affected.

To achieve more predictable cash flows and to reduce our exposure to adverse fluctuations in the prices of oil and gas, we have entered into and may in the future enter into hedging transactions for certain of our expected oil and natural gas production. These transactions could result in both realized and unrealized hedging losses. Further, these hedges may be inadequate to protect us from continuing and prolonged declines in the price of oil and natural gas. To the extent that the prices of oil and natural gas remain at current levels or declines further, we will not be able to hedge future production at the same level as our current hedges, and our results of operations and financial condition would be negatively impacted.

The extent of our commodity price exposure is related largely to the effectiveness and scope of our derivative activities. For example, the derivative instruments we utilize are primarily based on NYMEX futures prices, which may differ significantly from the actual crude oil and gas prices we realize in our operations. Furthermore, we have adopted a policy that requires, and our revolving credit facility also requires, that we enter into derivative transactions related to only a portion of our expected production volumes and, as a result, we will continue to have direct commodity price exposure on the portion of our production volumes not covered by these derivative financial instruments.

Our actual future production may be significantly higher or lower than we estimate at the time we enter into derivative transactions. If our actual future production is higher than we estimated, we will have greater commodity price exposure than we intended. If our actual future production is lower than the nominal amount that is subject to our derivative financial instruments, we might be forced to satisfy all or a portion of our derivative transactions without the benefit of the cash flow from our sale or purchase of the underlying physical commodity, resulting in a substantial diminution in our profitability and liquidity. As a result of these factors, our derivative activities may not be as effective as we intend in reducing the volatility of our cash flows, and in certain circumstances may actually increase the volatility of our cash flows.

In addition, our hedging transactions are subject to the following risks:

• we may be limited in receiving the full benefit of increases in oil and gas prices as a result of these transactions;

• a counterparty may not perform its obligation under the applicable derivative financial instrument or may seek bankruptcy protection;

• there may be a change in the expected differential between the underlying commodity price in the derivative instrument and the actual price received; and

• the steps we take to monitor our derivative financial instruments may not detect and prevent violations of our risk management policies and procedures, particularly if deception or other intentional misconduct is involved.



The enactment of derivatives legislation and regulation could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with our business.

In 2010, new comprehensive financial reform legislation, known as the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”), was enacted that established federal oversight regulation of over-the-counter derivatives market and entities, such as us, that participate in that market. Dodd-Frank requires the Commodities Futures Trading Commission, or CFTC, the SEC and other regulators to promulgate rules and regulations implementing the new legislation. The final rules adopted under Dodd-Frank identify the types of products and the classes of market participants subject to regulation and will require us in connection with certain derivatives activities to comply with clearing and trade-execution requirements (or take steps to qualify for an exemption from such requirements). While most of the regulations have been finalized, it is not possible at this time to predict with certainty the full effects of Dodd-Frank and CFTC rules on us or the timing of such effects. We believe that Dodd-Frank and associated regulations could significantly increase the cost of derivative contracts from additional recordkeeping and reporting requirements and through requirements to post collateral which could adversely affect our available liquidity. If we reduce our use of derivatives as a result of Dodd-Frank and associated regulations, our results of operations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital expenditures. These consequences could have a material adverse effect on our consolidated financial position, results of operations and cash flows.

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 oil and natural gas from many reservoirs including the Haynesville shale, Bossier shale, Eagle Ford shale, Tuscaloosa Marine shale, 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 currently being drilled by us utilize hydraulic fracturing in their completion and hydraulic fracturing services comprise approximately 45% of our capital budget in 2018.

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 coverage will be net of a deductible per occurrence 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 2012 requiring disclosure to the Railroad Commission of Texas and the public of certain



information regarding the components used in the hydraulic-fracturing process. The United States Congress has considered legislation that, if implemented, would subject the process of hydraulic fracturing to regulation under the Safe Drinking Water Act. In June 2015, the EPA released a draft report on the potential impacts of hydraulic fracturing on drinking water resources, which concluded that hydraulic fracturing activities have not led to widespread, systemic impacts on drinking water resources in the United States, although there may be above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water resources. The draft report was finalized in December 2016. Other governmental agencies, including the U.S. Department of Energy, have evaluated or are evaluating various other aspects of hydraulic fracturing. These ongoing or proposed studies have the potential to impact the likelihood or scope of future legislation or regulation.

State and federal regulatory agencies have recently focused on a possible connection between the hydraulic fracturing related activities and the increased occurrence of seismic activity. When caused by human activity, such events are called induced seismicity. In a few instances, operators of injection wells in the vicinity of seismic events have been ordered to reduce injection volumes or suspend operations. Some state regulatory agencies, including those in Colorado, Ohio, Oklahoma, and Texas, have modified their regulations to account for induced seismicity. Regulatory agencies at all levels are continuing to study the possible linkage between oil and gas activity and induced seismicity. A 2012 report published by the National Academy of Sciences concluded that only a very small fraction of the tens of thousands of injection wells have been suspected to be, or have been, the likely cause of induced seismicity; and a 2015 report by researchers at the University of Texas has suggested that the link between seismic activity and wastewater disposal may vary by region. In 2015, the United States Geological Survey identified eight states, including Texas, with areas of increased rates of induced seismicity that could be attributed to fluid injection or oil and gas extraction. More recently, in March 2016, the United States Geological Survey identified six states with the most significant hazards from induced seismicity, including Texas, Colorado, Oklahoma, Kansas, New Mexico, and Arkansas. In addition, a number of lawsuits have been filed, most recently in Oklahoma, alleging that disposal well operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. These developments could result in additional regulation and restrictions on the use of injection wells and hydraulic fracturing.

Changes in taxation as well as the inherent difficulty in quantifying potential tax effects of business decisions could have a material adverse effect on our results of operations, financial condition, or cash flows.

We make judgments regarding the utilization of existing income tax credits and the potential tax effects of various financial transactions and results of operations to estimate our obligations to taxing authorities. Tax obligations include income, franchise, real estate, sales and use, and employment-related taxes. These judgments include reserves for potential adverse outcomes regarding tax positions that have been taken. Changes in federal, state, or local tax laws, adverse tax audit results, or adverse tax rulings on positions taken by us could have a material adverse effect on our results of operations, financial condition, or cash flows.

The Budget Reconciliation Act, commonly referred to as the Tax Cuts and Jobs Act (hereinafter “Tax Cuts and Jobs Act”), was signed into law on December 22, 2017. In 2017 the Tax Cuts and Jobs Act resulted in a net tax benefit to us of approximately $19.1 million, which is attributable primarily to the termination of the corporate alternative minimum tax. The Tax Cuts and Jobs Act is expected to have a favorable impact on our effective tax rate and net income as reported under generally accepted accounting principles in future reporting periods to which the Tax Cuts and Jobs Act is effective. However, we are still assessing the full impact of the Tax Cuts and Jobs Act, including the impact on state taxes, and there can be no assurances that it will have a favorable impact on us or our future financial results.



## Loss of our information and computer systems could adversely affect our business.

We are heavily dependent on our information systems and computer-based programs, including our well operations information, seismic data, electronic data processing and accounting data. If any of such programs or systems were to fail or create erroneous information in our hardware or software network infrastructure or we were subject to cyberspace breaches or attacks, possible consequences include our loss of communication links, inability to find, produce, process and sell oil and natural gas and inability to automatically process commercial transactions or engage in similar automated or computerized business activities. Any such consequence could have a material effect on our business.

Our business could be negatively impacted by security threats, including cyber-security threats and other disruptions.

As an oil and natural gas producer, we face various security threats, including cyber-security threats to gain unauthorized access to sensitive information or to render data or systems unusable, threats to the safety of our employees, threats to the security or operation of our facilities and infrastructure or third party facilities and infrastructure, such as processing plants and pipelines, and threats from terrorist acts. Cyber-security attacks in particular are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data, and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. Although we utilize various procedures and controls to monitor and protect against these threats and to mitigate our exposure to such threats, there can be no assurance that these procedures and controls will be sufficient in preventing security threats from materializing. If any of these events were to materialize, either to the Company or a third party upon which we rely, they could lead to losses of sensitive information, critical infrastructure, personnel or capabilities, essential to our operations and could have a material adverse effect on our reputation, financial position, results of operations, or cash flows.

## We are exposed to the credit risk of our customers and counterparties, and our credit risk management may not be adequate to protect against such risk.

We are subject to the risk of loss resulting from nonpayment and/or nonperformance by our customers and counterparties in the ordinary course of our business. Our credit procedures and policies may not be adequate to fully eliminate customer and counterparty credit risk particularly in light of the sustained declines in oil and natural gas prices since mid-2014. We cannot predict to what extent our business would be impacted by deteriorating conditions in the economy, including declines in our customers' and counterparties' creditworthiness. If we fail to adequately assess the creditworthiness of existing or future customers and counterparties, unanticipated deterioration in their creditworthiness and any resulting increase in nonpayment and/or nonperformance by them could cause us to write-down or write-off doubtful accounts. Such write-downs or write-offs could negatively affect our operating results in the periods in which they occur and, if significant, could have a material adverse effect on our business, results of operations, cash flows and financial condition.

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 likely 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. Our cash flow from operations and access to capital is subject to a number of variables, including:

• our estimated proved reserves;

• the level of oil and natural gas we are able to produce from existing wells;

• our ability to extract natural gas liquids from the natural gas we produce;

• the prices at which oil, natural gas liquids and natural gas are sold; and

• our ability to acquire, locate and produce new reserves.

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.

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 prior years as the result of higher demand for these services. 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.

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 Chief Executive Officer, and Roland O. Burns, our President and Chief Financial Officer, and a limited number of other senior management personnel. Loss of the services of Mr. Allison, Mr. Burns 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.



Provisions of our restated 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 restated 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;

• requiring special stockholder meetings to be called only by our chairman of the board, our chief executive officer, a majority of the board, a majority of our executive committee or the holders of a majority of our outstanding stock;

• 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 1B. UNRESOLVED STAFF COMMENTS

None.

## ITEM 3. LEGAL PROCEEDINGS

We are not a party to any legal proceedings which management believes will have a material adverse effect on our consolidated results of operations or financial condition.

## 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.” All share and per share data presented herein has been restated to give effect to our one-for-five (1:5) reverse stock split that became effective on July 29, 2016.

## 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 1,309 producing oil and natural gas wells (721.2 net to us) and we operate 810 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 growth is driven primarily by our acquisition, development and exploration activities. In 2017 our growth in natural gas production and proved reserves was primarily driven by our successful drilling activities. Under our current drilling budget, we plan to spend up to $170.0 million in 2018 for development and exploration activities, which will primarily be focused on natural gas projects. We are currently planning to drill 31 horizontal natural gas wells (12.4 net to us) in 2018, targeting the Haynesville shales. The actual number of wells that we drill in 2018 will depend on natural gas prices.



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 or terminals. We have entered into certain transportation and treating agreements with midstream and pipeline companies to transport a substantial portion of our natural gas production in North Louisiana to long-haul gas 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 $10.4 million as of December 31, 2017.

Prices for crude oil and natural gas have been highly volatile, and we are currently experiencing a period of low prices primarily due to an oversupply of crude oil and natural gas. As prices remain low, we will continue to experience low revenues and cash flows. We expect our oil production to continue to decline until we resume drilling on our South Texas oil properties, which properties were classified as held for sale as of December 31, 2017. We expect our natural gas production to decline in the future to the extent that we do not offset this decline from production from the new wells we plan to drill in 2018 and future periods. Depending upon future prices and our production volumes, our cash flows from our operating activities may not be sufficient to fund our capital expenditures, and we may need to either curtail drilling activity or we may seek additional borrowings which would increase our interest expense in 2018 and in future periods.

We recognized $44.0 million of impairments of our proved oil and gas properties in 2017, primarily to adjust the carrying value of our assets held for sale to the estimated fair value less costs to sell at the end of the year. We may need to recognize further impairments if oil and natural gas prices remain low,



and as a result, the expected future cash flows from these properties becomes insufficient to recover their carrying value.

Oil and gas sales. Our oil and gas sales increased $79.6 million (45%) in 2017 to $255.3 million from $175.7 million in 2016 primarily due to the growth in our natural gas production driven by our Haynesville shale drilling program and higher oil and natural gas prices. Natural gas sales increased by $86.1 million (70%) from 2016 while oil sales decreased by $6.5 million from 2016. Our natural gas production increased by 37% from 2016 while our realized natural gas prices increased by 25%. The decrease in oil sales was attributable to the 31% decline in oil production which was partially offset by a 28% increase in our realized oil prices in 2017.

Production taxes. Production taxes increased $0.5 million or 9% to $5.4 million in 2017 from $4.9 million in 2016. The increase in 2017 was mainly due to the higher natural gas volumes and prices, which was partially offset by our lower oil revenues. Much of our natural gas sales in 2016 and 2017 qualified for a temporary exemption from state production taxes.

Gathering and transportation. Gathering and transportation costs in 2017 increased $1.7 million (11%) to $17.5 million as compared to $15.8 million in 2016 due to the 37% increase in natural gas we produced during 2017. Gathering and transportation per Mcf produced improved from 2016 as we were able to reduce the rates on certain of our transportation contracts in 2016 and 2017.

Lease operating expenses. Our lease operating expenses, including ad valorem taxes, of $37.9 million in 2017 were $9.8 million or 21% lower than our operating expenses of $47.7 million in 2016. Our lease operating expense per Mcfe produced decreased by 37% to $0.48 per Mcfe in 2017 as compared to $0.76 per Mcfe in 2016. The decrease in operating costs mainly reflects the higher volumes of natural gas produced, and lower costs associated with our declining oil production.



Exploration expense. We incurred exploration expense of $84.1 million in 2016 related to impairments of unevaluated leasehold costs. We did not incur any exploration expense in 2017.

Depreciation, depletion and amortization expense (“DD&A”). DD&A of $123.6 million decreased by $17.9 million (13%) from DD&A of $141.5 million in 2016. Our DD&A rate per Mcfe produced averaged $1.55 in 2017 as compared to $2.26 for 2016. The decrease in DD&A primarily resulted from the increase in production from our lower cost Haynesville shale properties.

General and administrative expenses. General and administrative expense of $26.1 million for 2017 was 9% higher than general and administrative expense of $24.0 million for 2016. The increase is primarily related to higher compensation costs for our employees. Stock-based compensation increased by $1.2 million to $5.9 million in 2017 as compared to $4.7 million in 2016.

Impairment of oil and gas properties. We recorded impairments to our oil and gas properties of $44.0 million and $27.1 million in 2017 and 2016, respectively. These impairments primarily relate to our South Texas oil assets held for sale at December 31, 2017 and our natural gas properties in South Texas that we sold in 2016.

Derivative financial instruments. We utilized oil and natural gas price swaps to manage our exposure to commodity prices and protect returns on investment from our drilling activities. We had a gain of $16.8 million and loss of $5.4 million on derivative financial instruments in 2017 and 2016, respectively. Our total net cash received from derivative financial instruments was $9.4 million in 2017 and $2.1 million in 2016.

The following table presents our natural gas and oil equivalent prices before and after the effect of cash settlements of our derivative financial instruments:

<table><tr><td>Average Realized Natural Gas Price:</td><td>2016</td><td>2017</td></tr><tr><td>Natural gas, per Mcf</td><td>$2.28</td><td>$2.84</td></tr><tr><td>Cash settlements on derivative financial instruments, per Mcf</td><td>0.04</td><td>0.13</td></tr><tr><td>Price per Mcf, including cash settlements on derivative financial instruments</td><td>$2.32</td><td>$2.97</td></tr></table>

Interest expense. Interest expense increased $17.7 million (14%) to $146.4 million in 2017 from interest expense of $128.7 million in 2016. The increase was primarily related to the amortization of the debt discounts recognized as a result of the gain recognized on debt exchange that we completed in 2016 and the amortization of costs incurred on the exchange.

Income taxes. Income taxes decreased in 2017 to a benefit of $17.9 million from a provision of $7.2 million in 2016 due to the effect of the tax law change in 2017. Our effective tax rate of 14% in 2017 differed from the federal income tax rate of 35% primarily due to recognition of the effect of the Tax Cuts and Jobs Act, which primarily reflects the favorable effect of eliminating the corporate alternative minimum tax.

Net loss. We reported a net loss of $111.4 million or $7.61 per share for 2017 as compared to a loss of $135.1 million or $11.52 per share for 2016. The net loss in 2017 was primarily due to the amortization of debt premium and deferred financing costs related to our 2016 debt restructuring and the impairment of our assets held for sale. The net loss in 2016 was primarily due to impairments of proved and unproved properties and other exploration costs.

(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 decreased $76.7 million (30%) in 2016 to $175.7 million from $252.4 million in 2015 due to the decline in our oil production and lower oil and natural gas prices. Oil sales decreased by $89.6 million (63%) from 2015 while our natural gas sales increased by $12.9 million (12%) from 2015. The decrease in oil sales was attributable to the 55% decline in oil production combined with a 17% decrease in our realized oil price in 2016. Our natural gas production increased by 13% from 2015 while our realized natural gas price decreased by 1%. Our drilling activity primarily in the Haynesville shale fields in North Louisiana generated the natural gas production growth.

Production taxes. Our production taxes decreased $5.4 million or 52% to $4.9 million in 2016 from $10.3 million in 2015. The decrease in 2016 is mainly due to the 63% decline in our oil sales during the year. Much of our natural gas sales in 2015 and 2016 qualified for temporary exemption from state production taxes.

Gathering and transportation. Gathering and transportation costs in 2016 increased $1.5 million (11%) to $15.8 million as compared to $14.3 million in 2015 due to the 13% increase in natural gas we produced during 2015. Gathering and transportation per Mcf produced improved from 2015 as the additional volumes produced in the Haynesville shale properties allowed us to lower our unit transportation costs.

Lease operating expenses. Our lease operating expenses, including ad valorem taxes, of $47.7 million in 2016 were $16.8 million or 26% lower than our operating expenses of $64.5 million in 2015. Our lease operating expense per Mcfe produced decreased by 22% to $0.76 per Mcfe in 2016 as compared to $0.97 per Mcfe in 2015. The decrease is mainly due to our divestitures made in 2015 and 2016, the lower oil production level and our efforts to reduce field operating costs related to our oil properties.

Exploration expense. We incurred $84.1 million in exploration expense in 2016 as compared to $70.7 million in 2015. Exploration expense in 2016 related to impairments of unevaluated leasehold



costs. Our 2015 exploration cost consisted of $69.0 million of impairments of unevaluated leasehold costs, and $1.7 million in rig termination fees.

DD&A. DD&A of $141.5 million decreased by $179.8 million (56%) from DD&A of $321.3 million in 2015. Our DD&A rate per Mcfe produced averaged $2.26 in 2016 as compared to $4.84 for 2015. The decrease in DD&A expense and the DD&A rate primarily resulted from the impairments to the carrying values of our producing properties that we recognized in 2015 and the increase in production from our lower cost natural gas properties in 2016.

General and administrative expenses. General and administrative expense of $24.0 million for 2016 was 2% higher than general and administrative expense of $23.5 million for 2015 primarily due to higher employee compensation in 2016. In 2015 we did not pay any employee bonuses. Stock based compensation which is included in general and administrative costs decreased to $4.7 million in 2016 as compared to $8.1 million in 2015.

Impairment of oil and gas properties. We assess the need for impairment of the capitalized costs for our oil and gas properties on a property basis. During 2016, we recognized an impairment charge of $27.1 million on our oil and gas properties, primarily to impair our South Texas properties that were classified as held for sale during most of 2016 until the properties were sold in December 2016. During 2015 we recognized an impairment charge of $80.3 million which mainly reflected the substantial decline in management’s estimates of longer-term future oil and natural gas prices.

Derivative financial instruments. We utilized natural gas price swaps to manage our exposure to commodity prices and protect returns on investment from our drilling activities. We had a loss of $5.4 million and a gain $2.7 million related to our derivative financial instruments in 2016 and 2015, respectively. The total net cash received from our derivative financial instruments was $2.1 million and $1.2 million in 2016 and 2015, respectively.

The following tables present our oil and natural gas prices before and after the effect of cash settlements of our derivative financial instruments held for natural gas price risk management:

<table><tr><td>Average Realized Natural Gas Price:</td><td>2015</td><td>2016</td></tr><tr><td>Natural gas, per Mcf</td><td>$2.30</td><td>$2.28</td></tr><tr><td>Cash settlements on derivative financial instruments, per Mcf</td><td>0.03</td><td>0.04</td></tr><tr><td>Price per Mcf, including cash settlements on derivative financial instruments</td><td>$2.33</td><td>$2.32</td></tr></table>

Interest expense. Interest expense increased $10.1 million (9%) to $128.7 million in 2016 from interest expense of $118.6 million in 2015. We did not capitalize any interest in 2016 and we capitalized interest of $0.9 million in 2015 related to our unevaluated properties. $11.9 million of our interest expense in 2016 related to our convertible notes, which is paid in-kind and due on maturity of the notes. $12.6 million of our interest expense in 2016 relates to the discount recorded from the debt exchange we completed with our senior note holders in September 2016. The original issue discount is being recognized over the lives of the new senior notes that were issued in the debt exchange and results from the $106.2 million gain recognized on the exchange of our unsecured senior notes for the convertible notes.

Income taxes. We had a provision for income taxes in 2016 of $7.2 million and a benefit from income taxes of $154.4 million in 2015. The provision in 2016 relates to state law changes enacted in 2016 which limit our ability to use state net operating loss carryforwards in the future. We had no federal tax provision in 2016 due to the net loss for the year, against which we recognized a full valuation



allowance. Our tax rate of 13% in 2015 differed from the federal income tax rate of 35% primarily due to the recognition of a valuation allowance on deferred tax assets of $283.6 million.

Net loss. We reported a loss of $135.1 million or $11.52 per share for 2016 as compared to a loss of $1.0 billion or $113.53 per share for 2015. The losses in 2016 and 2015 were primarily related to lower oil and natural gas prices, oil and gas property impairment charges recognized, and the loss on sale of oil and gas properties.

## Liquidity and Capital Resources

Funding for our activities has historically been provided by our operating cash flow, debt or equity financings and asset sales. For 2017, our primary source of funds was operating cash flow. Cash provided by operating activities in 2017 was $174.6 million as compared to cash used for operating activities of $23.7 million in 2016. This increase in operating cash flow is primarily due to our higher natural gas sales volumes and higher oil and natural gas prices.

For 2016, our primary source of funds was cash on hand and proceeds from asset sales of $27.9 million. Cash used for operating activities in 2016 was $23.7 million as compared to cash provided by operating activities of $30.1 million in 2015. The decrease in operating cash flow is primarily due to lower oil and gas sales.

Our capital expenditure activity is summarized in the following table:

<table><tr><td rowspan="3"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2015</td><td>2016</td><td>2017</td><td></td></tr><tr><td colspan="4">(In thousands)</td></tr><tr><td>Exploration and development:</td><td></td><td></td><td></td><td></td></tr><tr><td>Acquisitions of unproved oil and gas properties</td><td>$ 12,972</td><td>$ —</td><td>$ —</td><td></td></tr><tr><td>Developmental leasehold costs</td><td>767</td><td>3,267</td><td>4,698</td><td></td></tr><tr><td>Development drilling</td><td>184,393</td><td>50,711</td><td>164,472</td><td></td></tr><tr><td>Exploratory drilling</td><td>11,985</td><td>—</td><td>—</td><td></td></tr><tr><td>Other development costs</td><td>31,237</td><td>5,569</td><td>9,644</td><td></td></tr><tr><td></td><td>241,354</td><td>59,547</td><td>178,814</td><td></td></tr><tr><td>Other</td><td>1,893</td><td>69</td><td>43</td><td></td></tr><tr><td>Total</td><td>$243,247</td><td>$59,616</td><td>$178,857</td><td></td></tr></table>

The timing of most of our capital expenditures is discretionary because we have no material long-term capital expenditure commitments. 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 $170.0 million in 2018 for development and exploration projects including drilling 31 horizontal wells, completing 14 wells drilled in 2017, to re-frac five existing wells and for other development projects. Our operating cash flow and, therefore, our capital expenditures are highly dependent on oil and natural gas prices that we realize in 2018. We operate most of our properties and as a result have significant discretion over the amount and timing of our future capital expenditures.

We do not have a specific acquisition budget for 2018 because the timing and size of acquisitions are unpredictable. 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.



On September 6, 2016, we completed a debt exchange with the holders of approximately 98% of our then outstanding senior notes. Specifically, we issued (i) $697.2 million of new 10% Senior Secured Toggle Notes due 2020 and warrants exercisable for 1,917,342 shares of our common stock, in exchange for $697.2 million of our 10% Senior Secured Notes due 2020, (ii) $270.6 million of new 7 \( ^{3} $ 4% Convertible Second Lien PIK Notes due 2019 in exchange for $270.6 million of our 7 \( ^{3} $ 4% Senior Notes due 2019, and (iii) $169.7 million of new 9 \( ^{1} $ 2% Convertible Second Lien PIK Notes due 2020 in exchange for $169.7 million of our 9 \( ^{1} $ 2% Senior Notes due 2020. Accrued and unpaid interest on notes tendered in the exchange was paid in cash. Following the exchange, $2.8 million of our 10% Senior Secured Notes, $18.0 million of our 7 \( ^{3} $ 4% Senior Notes and $4.9 million of our 9 \( ^{1} $ 2% Senior Notes remained outstanding.

The exchange of the 10% Senior Secured Notes due 2020 for the 10% Senior Secured Toggle Notes due 2020 was accounted for as a modification of debt. Accordingly, no gain or loss was recognized on the exchange. The value of the warrants issued to the noteholders in consideration of the exchange is being amortized to interest expense over the life of the notes. Transaction costs of $4.5 million related to the exchange were recognized in 2016 as a reduction to the gain on extinguishment of debt, which is reported as a component of other income (loss). The exchange of the 7 \( ^{3} $ 4% Senior Notes due 2019 and the 9 \( ^{1} $ 2% Senior Notes due 2020 for the Convertible Second Lien PIK Notes was accounted for as a debt extinguishment given the substantial difference in the terms of the exchanged notes. A gain of $106.2 million on extinguishment of debt was recognized in 2016 on this exchange representing the difference between the fair market value of the new convertible notes and the carrying amount of the 7 \( ^{3} $ 4% Senior Notes and the 9 \( ^{1} $ 2% Senior Notes that were exchanged. Transaction costs of $6.5 million related to these exchanges have been reflected as debt issuance costs which are being amortized to interest expense over the lives of the notes.

Interest on the 10% Senior Secured Toggle Notes is payable on March 15 and September 15, and the notes mature on March 15, 2020. We have the option to pay up to $75.0 million of accrued interest by issuing additional notes. To the extent that interest is paid in-kind, the interest rate increases to 12 \( ^{1/4} \) % only for that interest payment and would result in an additional $91.9 million of notes outstanding.

Interest on the 7 \( ^{3} $ 4% Convertible Second Lien PIK Notes is payable on April 1 and October 1, and these notes mature on April 1, 2019. Interest on the 9 \( ^{1} $ 2% Convertible Second Lien PIK Notes is payable on June 15 and December 15, and these notes mature on June 15, 2020. Interest on the convertible notes is only payable in-kind. Each series of the convertible notes are convertible, at the option of the holder, into 81.2 shares of our common stock for each 1,000 of principal amount of notes. The convertible notes will mandatorily convert into 81.2 shares of common stock for each 1,000 of principal amount of the notes following a 15 consecutive trading day period during which the daily volume weighted average price of our common stock is equal to or greater than 12.32 per share. 9.9 million of principal amount of the convertible notes plus accrued interest thereon were converted into 826,327 shares of common stock during 2017.

Prior to the completion of the debt exchange, we retired $87.5 million in principal amount of the 7 \( ^{3} $ 4% Senior Notes and $19.8 million of the 9 \( ^{1} $ 2% Senior Notes in 2016 in exchange in the aggregate for the issuance of 2,748,403 shares of common stock and $3.5 million in cash. A gain on extinguishment of debt of $89.6 million was recognized on the retirement of the senior notes during 2016 for the difference between the market value of the stock and the net carrying value of the debt. During 2015, we acquired $23.9 million in principal amount of the 7 \( ^{3} $ 4% Senior Notes and $105.6 million in principal amount of the 9 \( ^{1} $ 2% Senior Notes for an aggregate purchase price of $42.7 million. The gain of $82.4 million recognized on the purchase of the senior notes and the loss resulting from the write-off of deferred loan costs associated with our prior bank credit facility of $3.7 million are included in the net gain on extinguishment of debt in 2015.



We have a $50.0 million revolving credit facility with Bank of Montreal and Bank of America, N.A. that matures on March 4, 2019. As of December 31, 2017 there were no borrowings outstanding under the revolving credit facility. Indebtedness under the revolving credit facility is guaranteed by all of our subsidiaries and is secured by substantially all of our and our subsidiaries' assets. Borrowings under the revolving credit facility bear interest, at our option, at either (1) LIBOR plus 2.5% 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 1.5%. A commitment fee of 0.5% per annum is payable quarterly on the unused credit line. The revolving credit facility contains covenants that, among other things, restrict the payment of cash dividends and repurchases of common stock, limit the amount of additional debt that we may incur and limit our ability to make certain loans, investments and divestitures. The only financial covenants are the maintenance of a ratio of current assets, including availability under the credit facility, to current liabilities of at least 0.9 to 1.0 which increases to 1.0 to 1.0 on March 31, 2018 and the maintenance of an asset coverage ratio of proved developed oil and natural gas reserves to the amount outstanding under the revolving credit facility of at least 2.5 to 1.0. We were in compliance with these covenants as of December 31, 2017.

All of our subsidiaries guarantee the bank credit facility, the 10% Senior Secured Toggle Notes, the 7 \( ^{3} $ 4% Convertible Second Lien PIK Notes, the 9 \( ^{1} $ 2% Convertible Second Lien PIK Notes, and the other outstanding senior notes. The bank credit facility, the 10% Senior Secured Toggle Notes and the convertible notes are secured by liens on substantially all of our and our subsidiaries' assets. The allocation of proceeds related to the liens on our assets are governed by intercreditor agreements granting priority to the bank credit facility. Proceeds from liens on the convertible notes are also subject to the priority of the 10% Senior Secured Toggle Notes. The liens that previously secured the 10% Senior Secured Notes that were not tendered for exchange were released and these notes are no longer secured.

The following table summarizes our aggregate liabilities and commitments by year of maturity:

Future interest costs are based upon the effective interest rates of our outstanding senior notes. Future principal amounts due for our convertible notes are inclusive of paid in-kind interest through the maturity dates of these notes. The table assumes that interest on the 10% Senior Secured Toggle Notes is not paid in-kind.

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 2021. We record a separate liability for these asset retirement obligations, which totaled $10.4 million as of December 31, 2017.

We believe that our cash on hand and cash flow from operations and available borrowings under our bank credit facility is sufficient to fund our 2018 planned operating activities. If our plans or assumptions



change or our assumptions prove to be inaccurate, we may be required to seek additional capital, including additional equity or debt financings to replace any liquidity that may be lost from low oil and natural gas prices. 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.

## Federal and State Taxation

At December 31, 2017, we had $923.7 million in U.S. federal net operating loss carryforwards and $1.5 billion in certain state net operating loss carryforwards. We have established a valuation allowance against all of the federal loss carryforwards and $1.4 billion of the state loss carryforwards due to the uncertainty of generating future taxable income prior to the expiration of the net operating loss carryforward periods.

Future use of our net operating loss carryforwards may be limited in the event that a cumulative change in the ownership of our common stock by more than 50% occurs within a three-year period. Such a change in ownership could result in a substantial portion of our net operating loss carryforwards being eliminated or becoming restricted. It is highly likely that a change in ownership that would result from conversion of our convertible notes would result in limits on the future use of our net operating loss carryforwards.

The Tax Cuts and Jobs Act, which was enacted on December 22, 2017, reduced the corporate income tax rate effective January 1, 2018 from 35% to 21%. Among the other significant tax law changes that affect us are the elimination of the corporate alternative minimum tax (“AMT”), changes that require operating losses incurred in 2018 and beyond be carried forward indefinitely with no carryback up to 80% of taxable income in a given year, and limitations on the deduction for interest expense incurred in 2018 or later of up to 70% of our taxable income for the taxable year. The Tax Cuts and Jobs Act preserved deductibility of intangible drilling costs for federal income tax purposes, which allows us to deduct a portion of drilling costs in the year incurred and minimizes current taxes payable in periods of taxable income. At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Tax Cuts and Jobs Act; however, we have made reasonable estimates of the effects on our existing deferred tax balances. We have remeasured certain deferred federal tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. The provisional amount recognized related to the remeasurement of our deferred federal tax balance was $140.4 million, which was subject to a valuation allowance at December 31, 2017. The Tax Cuts and Jobs Act also repealed the AMT for tax years beginning on or after January 1, 2018 and provides that existing AMT credit carryforwards can be utilized to offset federal taxes for any taxable year. In addition, 50% of any unused AMT credit carryforwards can be refunded during tax years 2018 through 2020 with any remaining AMT credit carryforward being fully refunded in 2021. We accordingly reversed the valuation allowance on our AMT credit carryforward of $19.1 million that will now be refundable through 2021 and have reclassified this amount from a deferred tax asset to a non-current receivable. We are still analyzing certain aspects of the Tax Cuts and Jobs Act, and refining our calculations, which could potentially affect the measurement of those balances or potentially give rise to new deferred tax amounts. Our estimates may also be affected in the future as we gain a more thorough understanding of the Tax Cuts and Jobs Act, and how the individual states are implementing this new law.

Our federal income tax returns for the years subsequent to December 31, 2013 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, 2012. We currently believe that our significant filing positions are highly certain and that all of our other 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.

## 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 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 and timing 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 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 reserves 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 a corporate forecast which considers forecasts from multiple independent price forecasts. 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. During 2017, we recognized impairment charges of $44.0 million to reduce the capitalized costs of our evaluated oil and natural gas properties, which included $43.8 million that was recognized to reduce the carrying value of certain of our assets to their fair value less costs to sell prior to their sale. It is reasonably possible that our estimates of undiscounted future net cash flows attributable to its oil and gas properties may change in the future. The primary factors that may affect estimates of future cash flows include future adjustments, both positive and negative, to proved and appropriate risk-adjusted probable oil and gas reserves, results of future drilling activities, future prices for oil and natural gas, and increases or decreases in production and capital costs. As a result of these changes, there may be further impairments in the carrying values of our evaluated oil and gas properties.

Income Taxes. We account 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.

In recording deferred income tax assets, we consider whether it is more likely than not that some portion or all of our deferred income tax assets will be realized in the future. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those deferred income tax assets would be deductible. We believe that after considering all the available objective evidence, historical and prospective, with greater weight given to historical evidence, we are not able to determine that it is more likely than not that all of our deferred tax assets will be realized. As a result, we established valuation allowances for our deferred tax assets and U.S. federal and state net operating loss carryforwards that are not expected to be utilized due to the uncertainty of generating taxable income prior to the expiration of the carryforward periods. We will continue to assess the valuation allowances against deferred tax assets considering all available information obtained in future reporting periods.

Future use of our federal and state net operating loss carryforwards may be limited in the event that a cumulative change in the ownership of our common stock by more than 50% occurs within a three-year period. Such a change in ownership would result in a substantial portion of our net operating loss carryforwards being eliminated or becoming restricted, and we would need to recognize additional valuation allowances reflecting the restricted use of the net operating loss carryforwards in the period when such an ownership change occurred. It is highly likely that a change in ownership that would result from conversion of our convertible notes would result in limits on the future use of its net operating loss carryforwards.

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.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under existing generally accepted accounting principles. This new standard is based upon the principal that revenue is recognized to depict the transfer



of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2017. We have completed our review of our primary oil and natural gas marketing agreements in order to assess the impact of adoption, and we have assessed that adoption of this standard will not have a material impact on our financial statements because revenue will continue to be recognized as production is delivered. We are adopting this new standard in the first quarter of 2018 using the modified retrospective method.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to include most leases on their balance sheets, but recognize lease costs in their financial statements in a manner similar to accounting for leases prior to ASC 2016-02. ASU 2016-02 is effective for annual periods ending after December 15, 2018 and interim periods thereafter. Early adoption is permitted. We are currently evaluating the new guidance and anticipate that certain operating leases that we have in place will be reflected as both an asset and a liability in our consolidated balance sheet. We have not determined which method of adoption we will apply for this new standard.

## 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 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 effect 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 2017, and taking into account any oil or natural gas price swap agreements we had in place, 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 $0.9 million and a $0.10 change in the price per Mcf of natural gas would have changed our cash flow by approximately $4.1 million.

As of December 31, 2017, we have entered into natural gas price swap agreements covering 2.6 Bcf of our expected 2018 natural gas production that fix the NYMEX price at $3.38 per Mcf. As of December 31, 2017, our outstanding natural gas swap agreements represented an asset with a fair value of $1.3 million. The change in the fair value of our natural gas swaps that would result from a 10% change in commodities prices at December 31, 2017 would be $0.3 million. Such a change in fair value could be a gain or a loss depending on whether prices increase or decrease. Since December 31, 2017, we have entered into additional natural gas price swap agreements which increased our hedged natural gas production to 24.2 Bcf with a fixed NYMEX price of $3.04 per Mcf.



## Interest Rates

At December 31, 2017, we had approximately $1.2 billion principal amount of long-term debt outstanding. All but $25.6 million of this debt is secured by substantially all of our assets. Of this amount, our first lien notes of $697.2 million bear interest at a fixed rate of 10%, $284.4 million of our convertible notes bear interest at a fixed rate of 7 \( ^{3}/_{4} $ % and $187.1 million of our convertible notes bear interest at a fixed rate of 9 \( ^{1}/_{2} \) %. At our option, up to $75.0 million of the interest payable on the first lien notes can be paid in-kind. All of the interest on the convertible notes is payable in-kind, and these notes are convertible into our common stock either at the option of the note holders, or mandatorily upon the attainment of certain specific contractual terms. The $25.6 million of unsecured senior notes bear interest at rates of between 7 \( ^{3}/_{4} \) % to 10% and mature in 2019 and 2020. The fair market value of our fixed rate debt as of December 31, 2017 was $1.2 billion based on the market price of approximately 99% of the face amount of such debt. At December 31, 2017, we had no borrowings outstanding under our revolving credit facility, which is subject to variable rates of interest that are tied at our option to either LIBOR or the corporate base rate.

## ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

None.

## ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Controls and Procedures. Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act) are designed to provide reasonable assurance that information required to be disclosed in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.



We performed an evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2017. The evaluation was performed with the participation of senior management of each business segment and key corporate functions, and under the supervision of the Chief Executive Officer and Chief Financial Officer.

Based on our evaluation of our disclosure controls and procedures, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2017 to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and to provide reasonable assurance that information required to be disclosed by us is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting. There were no changes in our internal control over financial reporting during the quarter ended December 31, 2017 that materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting. We are responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, we conducted an assessment, including testing, using the criteria in Internal Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Our system of internal control over financial reporting is 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. 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. As of December 31, 2017, we assessed the effectiveness of the Company’s internal control over financial reporting based on the COSO criteria, and based on that assessment we determined that the Company maintained effective internal control over financial reporting as of December 31, 2017.

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, 2017. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, follows below.

## Definition and Limitations of Internal Control Over Financial Reporting

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.

# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
Comstock Resources, Inc.

## Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Comstock Resources, Inc. and subsidiaries (the Company) as of December 31, 2016 and 2017, and the related consolidated statements of operations, stockholders' deficit and cash flows for each of the three years in the period ended December 31, 2017, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2016 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 26, 2018 expressed an unqualified opinion thereon.

## Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2003.

# COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## (1) Summary of Significant Accounting Policies

Accounting policies used by Comstock Resources, Inc. and subsidiaries 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. and its subsidiaries are 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”). 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. Net loss and comprehensive loss are the same in all periods presented.

On July 29, 2016, the Company effected a one for five (1:5) reverse split of its outstanding shares of common stock. All amounts disclosed in these financial statements have been adjusted to give effect to this reverse stock split in all periods.

Management of the Company has assessed the Company’s financial condition, the current capital markets and its future plans given different scenarios of oil and natural gas prices and believes the Company has adequate liquidity to fund its operations for at least twelve months from the date of issuance of these financial statements, which is the requirement to be considered a going concern under generally accepted accounting principles. Management cannot predict how an extended period of low oil and natural gas prices will affect the Company’s future operations and liquidity levels.

## 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 analyses 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’s policy is to assess the collectability of its



# COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

receivables based upon their age, the credit quality of the purchaser or participant and the potential for revenue offset. 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.

## Other Current Assets

Other current assets at December 31, 2016 and 2017 consist of the following:

<table><tr><td rowspan="3"></td><td colspan="2">As of December 31,</td></tr><tr><td>2016</td><td>2017</td></tr><tr><td colspan="2">(In thousands)</td></tr><tr><td>Pipe and oil field equipment inventory</td><td>$ 1,183</td><td>$ 998</td></tr><tr><td>Production tax refunds receivable</td><td>303</td><td>1,409</td></tr><tr><td>Other</td><td>338</td><td>338</td></tr><tr><td></td><td>$ 1,824</td><td>$2,745</td></tr></table>

## Fair Value Measurements

Certain accounts within the Company’s consolidated balance sheets are required to be measured at fair value on a recurring basis. These include cash equivalents held in bank accounts and derivative financial instruments in the form of oil and 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 cash equivalents valuation is 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 is determined utilizing a discounted cash flow model based on inputs that are readily available in



# COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

public markets and, accordingly, the valuation of these swap agreements, is categorized as a Level 2 measurement. There are no financial assets or liabilities accounted for at fair value as of December 31, 2017 that are a Level 3 measurement.

At December 31, 2017, the Company had an asset for the fair value of its natural gas price swap agreements of $1.3 million. The Company had a liability for the fair value of derivative financial instruments outstanding at December 31, 2016 of $6.0 million. There were no offsetting swap positions in 2016 or 2017. The change in fair value of these natural gas swaps was recognized as a gain or loss and included as a component of other income (expense).

As of December 31, 2017, the Company’s other financial instruments, comprised solely of its fixed rate debt, had a carrying value of $1.1 billion and a fair value of $1.2 billion. As of December 31, 2016, the Company’s fixed rate debt had a carrying value of $1.1 billion and a fair value of $1.1 billion. The fair market value of the Company’s fixed rate debt was based on quoted prices as of December 31, 2017 and December 31, 2016, a Level 2 measurement.

## Property and Equipment

The Company follows the successful efforts method of accounting for its oil and gas properties. Costs incurred to acquire oil and gas leasehold are capitalized. Acquisition costs for proved oil and 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. Amortization is calculated at the field level. 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 for impairment on a property by property basis, and any impairment in value is charged to exploration expense. During 2015 and 2016, impairment charges of $68.9 million and $84.1 million, respectively, were 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 evaluated oil and gas properties on a property-by-property 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 Company determines the fair values of its oil and gas properties using a discounted cash flow model and proved and risk-adjusted probable reserves. Undrilled acreage is valued based on sales transactions in comparable areas. Significant Level 3 assumptions associated with the calculation of discounted future



## COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

cash flows included in the cash flow model include management’s outlook for oil and natural gas prices, future oil and natural gas production, production costs, capital expenditures, and the total proved and risk-adjusted probable oil and natural gas reserves expected to be recovered. Management’s oil and natural gas price outlook is developed based on third-party longer-term price forecasts as of each measurement date. The expected future net cash flows are discounted using an appropriate discount rate in determining a property’s fair value. 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.

Comstock sold various oil and gas properties in 2017 for total proceeds of $1.5 million and recognized a loss of $1.1 million on these divestitures. The Company also recognized an impairment of $43.8 million to adjust the carrying value of the Company’s South Texas oil properties to fair value less costs to sell of $198.6 million when the assets were designated as held for sale in the fourth quarter of 2017. We determined the fair value based on estimated discounted future net cash flows of the properties appropriately risk adjusted based on indication of values received from potential acquirers in a competitive bid process. There can be no assurance that we will ultimately be able to complete a sale of the properties at the estimated fair value. In 2016, the Company recognized impairments of $27.1 million on certain of its oil and gas properties, including an impairment of $20.8 million to adjust the carrying value of the Company’s South Texas natural gas properties to fair value of $42.5 million when the assets were designated as held for sale in the first quarter of 2016. The fair value of the other properties impaired in 2016 was $21.1 million.

In 2015, reductions to management’s oil and natural gas price outlook resulted in impairments of $801.3 million of the Company’s oil properties in South Texas and Mississippi, and certain of its natural gas properties in Texas and Louisiana. The following table presents the fair value and impairments recorded by the Company in the third quarter and fourth quarter of 2015, as well as the average oil price per barrel and gas price per thousand cubic feet over the life of the properties and the applicable discount rates utilized in the Company’s assessments:

<table><tr><td rowspan="2"></td><td rowspan="2">Fair Value (In thousands)</td><td rowspan="2">Impairment</td><td colspan="2">Management&#x27;s Price Outlook</td><td rowspan="2">Annual Discount Rate</td></tr><tr><td>Oil (Per barrel)</td><td>Gas (Per Mcf)</td></tr><tr><td>Impairments recorded at September 30, 2015:</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Oil properties</td><td>$330,257</td><td>$405,308</td><td>$73.70</td><td>$4.04</td><td>10%-20%</td></tr><tr><td>Natural gas properties</td><td>$ 61,625</td><td>$139,406</td><td>$75.91</td><td>$3.91</td><td>10%-20%</td></tr><tr><td>Impairments recorded at December 31, 2015:</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Oil properties</td><td>$ 3,030</td><td>$ 16,036</td><td>$73.48</td><td></td><td>10%-20%</td></tr><tr><td>Natural gas properties</td><td>$123,926</td><td>$238,210</td><td>$70.76</td><td>$3.74</td><td>10%-20%</td></tr></table>

The Company’s estimates of undiscounted future net cash flows attributable to its oil and gas properties may change in the future. The primary factors that may affect estimates of future cash flows include future adjustments, both positive and negative, to proved and appropriate risk-adjusted probable oil and natural gas reserves, results of future drilling activities, future prices for oil and natural gas, and increases or decreases in production and capital costs. As a result of these changes, there may be further impairments in the carrying values of these or other properties.



# COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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  \( \frac{1}{2} \)  years on a straight-line basis.

## Other Assets

Other assets primarily consist of deferred costs associated with the Company’s bank credit facility. These costs are amortized over 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.

## Accrued Expenses

Accrued expenses at December 31, 2016 and 2017 consist of the following:

<table><tr><td rowspan="3"></td><td colspan="2">As of December 31,</td></tr><tr><td>2016</td><td>2017</td></tr><tr><td colspan="2">(In thousands)</td></tr><tr><td>Accrued drilling costs</td><td>$ 7,498</td><td>$ 5,874</td></tr><tr><td>Accrued interest payable</td><td>22,721</td><td>21,277</td></tr><tr><td>Accrued transportation costs</td><td>2,227</td><td>3,269</td></tr><tr><td>Accrued employee compensation</td><td>6,292</td><td>6,449</td></tr><tr><td>Asset retirement obligation - assets held for sale</td><td>—</td><td>4,557</td></tr><tr><td>Other</td><td>1,628</td><td>1,029</td></tr><tr><td></td><td>$40,366</td><td>$42,455</td></tr></table>

## 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 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 statements of operations.

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

<table><tr><td></td><td>2016</td><td>2017</td></tr><tr><td></td><td colspan="2">(In thousands)</td></tr><tr><td>Reserve for Future Abandonment Costs at beginning of the year</td><td>$20,093</td><td>$15,804</td></tr><tr><td>New wells placed on production</td><td>3</td><td>7</td></tr><tr><td>Changes in estimates and timing</td><td>(553)</td><td>(1,260)</td></tr><tr><td>Liabilities settled</td><td>(409)</td><td>(77)</td></tr><tr><td>Assets held for sale</td><td>—</td><td>(4,557)</td></tr><tr><td>Asset divestitures</td><td>(4,268)</td><td>(320)</td></tr><tr><td>Accretion expense</td><td>938</td><td>810</td></tr><tr><td>Reserve for Future Abandonment Costs at end of the year</td><td>$15,804</td><td>$10,407</td></tr></table>

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

## Stock-based Compensation

The Company has stock-based employee compensation plans under which stock awards, comprised primarily of restricted stock and performance share units, are issued to employees and non-employee directors. 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.

## Segment Reporting

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

## Derivative Financial Instruments and Hedging Activities

The Company accounts for derivative financial instruments (including 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. 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.

## Major Purchasers

In 2015, the Company had two major purchasers of its oil and natural gas production that represented 52% and 25% of its total oil and gas sales. In 2016, the Company also had four major purchasers of its oil and natural gas production that represented 42%, 17%, 14% and 12% of its total oil and gas sales. In 2017, the Company had four major purchasers of its oil and natural gas production that accounted for 34%, 17%, 16% and 15% of its total oil and gas sales. The loss of any of these purchasers would not have a material adverse effect on the Company as there is an available market for its 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 recorded in the month of production based on an estimate of the Company’s share of volumes produced and prices realized. 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, 2016 or 2017. Sales of 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 gathering and transportation 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 $13.9 million, $12.4 million and $11.7 million in 2015, 2016 and 2017, respectively.



# COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

## 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 tax consequences attributable to the future utilization of existing net operating loss and other 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

Unvested share-based payment awards containing nonforfeitable rights to dividends are considered to be participating securities and included in the computation of basic and diluted earnings per share pursuant to the two-class method. Performance share units (“PSUs”) represent the right to receive a number of shares of the Company’s common stock that may range from zero to up to two times the number of PSUs granted on the award date based on the achievement of certain performance measures during a performance period. The number of potentially dilutive shares related to PSUs is based on the number of shares, if any, which would be issuable at the end of the respective period, assuming that date was the end of the contingency period. The treasury stock method is used to measure the dilutive effect of PSUs. Unexercised common stock warrants represent the right to convert the warrants into common stock at an exercise price of $0.01 per share. The treasury stock method is used to measure the dilutive effect of unexercised common stock warrants. The shares that would be issuable upon exercise of the conversion rights contains in the Company’s convertible debt for each period are based on the if-converted method for computing potentially dilutive shares of common stock that could be issued upon conversion. None of the Company’s participating securities participate in losses and as such are excluded from the computation of basic earnings per share during periods of net losses.

Basic and diluted earnings per share for the years ended December 31, 2015, 2016 and 2017 were determined as follows:

<table><tr><td rowspan="2"></td><td colspan="4">2015</td><td colspan="4">2016</td><td colspan="4">2017</td></tr><tr><td>Income (Loss)</td><td>Shares</td><td>Per Share</td><td>Loss (In thousands except per share data)</td><td>Shares</td><td>Per Share</td><td>Loss</td><td>Shares</td><td>Per Share</td><td>Loss</td><td>Shares</td><td>Per Share</td></tr><tr><td>Basic and Diluted Net Loss Attributable to Common Stock</td><td>$ (1,047,109)</td><td>9,223</td><td>$ (113.53)</td><td>$ (135,134)</td><td>11,729</td><td>$ (11.52)</td><td>$ (111,405)</td><td>14,644</td><td>$ (7.61)</td><td></td><td></td><td></td></tr></table>

Basic and diluted per share amounts are the same for the years ended December 31, 2015, 2016, and 2017 due to the net loss reported during each of those years.

At December 31, 2015, 2016 and 2017, 314,048, 354,986 and 619,867 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:

<table><tr><td></td><td>2015</td><td>2016</td><td>2017</td></tr><tr><td></td><td colspan="3">(In thousands)</td></tr><tr><td>Unvested restricted stock</td><td>293</td><td>344</td><td>612</td></tr></table>



## COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

## 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, 2015, 2016 and 2017, respectively, were as follows:

<table><tr><td></td><td>2015</td><td>2016</td><td>2017</td></tr><tr><td></td><td colspan="3">(In thousands)</td></tr><tr><td>Interest payments</td><td>$94,177</td><td>$105,449</td><td>$73,941</td></tr><tr><td>Income tax payments</td><td>$ 77</td><td>$ —</td><td>$ 3</td></tr></table>

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 did not capitalize interest in 2017 or 2016. The Company capitalized interest of $0.9 million in 2015. The Company also paid in-kind $11.9 million and $38.1 million of interest on its convertible notes in 2016 and 2017, respectively.

## Recent accounting pronouncements

On January 1, 2017, the Company adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The adoption of this new standard did not have a material impact on the Company’s financial statements. The Company is accounting for forfeitures in compensation cost as they occur, and it is applying the prospective transition method for presentation of the income tax effects of vested equity awards in its consolidated statements of cash flows.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under existing generally accepted accounting principles. This new standard is based upon the principal that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects



# COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2017. The Company has completed its review of its primary oil and natural gas marketing agreements in order to assess the impact of adoption, and it has assessed that adoption of this standard will not have a material impact on the Company’s financial statements because revenue will continue to be recognized as production is delivered. The Company is adopting this standard in the first quarter of 2018 utilizing the modified retrospective method.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to include most leases on their balance sheets, but recognize lease costs in their financial statements in a manner similar to accounting for leases prior to ASC 2016-02. ASU 2016-02 is effective for annual periods ending after December 15, 2018 and interim period thereafter. Early adoption is permitted. The Company is currently evaluating the new guidance and anticipates that certain operating leases that it has in place will be reflected as an asset and a liability in its consolidated balance sheet. The Company has not yet determined which method of adoption it will apply for this new standard.

## (2) Acquisitions and Dispositions of Oil and Gas Properties

In 2017, the Company entered agreements to jointly develop certain acreage prospective for the Haynesville shale in Louisiana and Texas with USG Properties Haynesville, LLC (“USG”). As of December 31, 2017, USG had acquired approximately 6,300 net acres prospective for Haynesville shale development for the joint development program primarily in Caddo Parish, Louisiana. The Company operates wells drilled on USG’s acreage and has the right to acquire a 25% working interest in the acreage by reimbursing USG for the attributable acreage costs of the wells being drilled increasing to 40% starting with the 13 \( ^{th} \)  well drilled. USG is also participating in four wells being drilled in the Company’s Bossier shale acreage in Sabine Parish, Louisiana and in a Haynesville shale drilling program on approximately 5,700 acres of Comstock’s acreage in Harrison County, Texas. Under the terms of the participation agreements for Sabine Parish and Harrison County acreage owned by the Company, Comstock will receive between 1.1 million and 1.4 million, respectively, for 50% of Comstock’s interest for each location for acreage and infrastructure related to each well location, with 400,000 of that amount being paid only if each well meets or exceeds established production targets. Comstock also receives 80,000 for each well drilled as consideration for the Company’s services managing the joint development program in addition to customary operating fees for each well drilled except for the four Bossier shale wells. Comstock and USG plan to continue to acquire additional acreage for the joint development program.

Results of operations for the properties that were sold and classified as held for sale in 2015, 2016 and 2017 were as follows:

## COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In October 2017, Comstock adopted a plan of sale for its oil properties located in South Texas. The Company recognized an impairment of $43.8 million in the fourth quarter of 2017 to adjust the carrying value of these assets to their fair value less costs to sell. We determined the fair value based on estimated discounted future net cash flows of the properties appropriately risk adjusted based on indication of values received from potential acquirers in a competitive bid process. There can be no assurance that we will ultimately be able to complete a sale of the properties at the estimated fair value. The asset retirement liability of $4.6 million associated with these assets was reclassified to current liabilities as of December 31, 2017. In December 2016, the Company sold certain of its natural gas properties located in South Texas realizing net proceeds of $25.8 million. The Company recognized a loss on the sale of these assets in 2016 totaling $13.4 million and an impairment of $20.8 million in the first quarter of 2016 to adjust the carrying value of these assets to their fair value. The Company also sold certain other oil and gas properties during 2016 for total proceeds of $2.1 million. The Company recognized a loss of $1.6 million on these divestitures. In July 2015, the Company sold its Burleson County, Texas properties for proceeds of $102.5 million, recognizing a net loss on sale of $112.1 million.

In January 2016, the Company exchanged certain oil and gas properties with another operator in a non-monetary exchange. Under the exchange, the Company received 3,637 net acres in DeSoto Parish, Louisiana, prospective for the Haynesville shale, including four producing wells (3.5 net). The Company exchanged 2,547 net acres in Atascosa County, Texas, including seven producing wells (5.3 net) for the Haynesville shale properties. The Company recognized a gain of $0.7 million on this transaction which was included in the loss on sale of oil and gas properties for the year ended December 31, 2016.

Interest on the 10% Senior Secured Toggle Notes is payable on March 15 and September 15, and the notes mature on March 15, 2020. The Company has the option to pay up to $75.0 million of accrued interest by issuing additional notes. To the extent that interest is paid in-kind, the interest rate increases to 12  \( \frac{1}{4} \) % only for that interest payment and would result in an additional $91.9 million of notes outstanding.

Interest on the 7 \( ^{3} $ 4% Convertible Second Lien PIK Notes is payable on April 1 and October 1, and these notes mature on April 1, 2019. Interest on the 9 \( ^{1} $ 2% Convertible Second Lien PIK Notes is payable on June 15 and December 15, and these notes mature on June 15, 2020. Interest on the convertible notes is only payable in kind. Each series of the convertible notes is convertible, at the option of the holder, into 81.2 shares of the Company’s common stock for each 1,000 of principal amount of notes. The convertible notes will mandatorily convert into 81.2 shares of common stock for each 1,000 of principal amount of the notes following a 15 consecutive trading day period during which the daily volume weighted average price of the Company’s common stock is equal to or greater than 12.32 per share.

On September 6, 2016, Comstock completed a debt exchange with the holders of approximately 98% of its then outstanding senior notes. Specifically, the Company issued (i) $697.2 million of new 10% Senior Secured Toggle Notes due 2020 and warrants exercisable for 1,917,342 shares of common stock, in exchange for $697.2 million of the Company’s 10% Senior Secured Notes due 2020, (ii) $270.6 million of new 7 \( ^{3} $ 4% Convertible Second Lien PIK Notes due 2019 in exchange for $270.6 million of the Company’s 7 \( ^{3} $ 4% Senior Notes due 2019, and (iii) $169.7 million of new 9 \( ^{1} $ 2% Convertible Second Lien PIK Notes due 2020 in exchange for $169.7 million of the Company’s 9 \( ^{1} $ 2% Senior Notes due 2020. Accrued and unpaid interest on notes tendered in the exchange was paid in cash. Following the exchange, $2.8 million of the 10% Senior Secured Notes, $18.0 million of the 7 \( ^{3} $ 4% Senior Notes and $4.9 million of the 9 \( ^{1} $ 2% Senior Notes remained outstanding.

The exchange of the 10% Senior Secured Notes due 2020 for the 10% Senior Secured Toggle Notes due 2020 was accounted for as a modification of debt. Accordingly no gain or loss was recognized on the exchange. The value of the warrants issued to the noteholders on September 6, 2016, a Level 2 measurement, is being amortized to interest expense over the life of the notes. Transaction costs of $4.5 million related to the exchange were recognized in 2016 as a reduction to the gain on extinguishment of debt which is reported as a component of other income (loss). The exchange of the 7 \( ^{3} $ 4% Senior Notes



## COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

due 2019 and the 9½% Senior Notes due 2020 for the Convertible Second Lien PIK Notes was accounted for as a debt extinguishment given the substantial difference in the terms of the exchanged notes. A gain of $106.2 million on extinguishment of debt was recognized in 2016 on this exchange representing the difference between the fair market value of the new convertible notes and the carrying amount of the 7¾% Senior Notes due 2019 and the 9½% Senior Notes due 2020 that were exchanged. Transaction costs of $6.5 million related to these exchanges have been reflected as debt issuance costs which are being amortized to interest expense over the lives of the notes. The Company determined the fair value of the convertible notes based upon the average trading prices for the notes subsequent to closing of the exchange. This valuation was a Level 2 measurement.

Prior to the completion of the debt exchange, the Company retired $87.5 million in principal amount of the 7 \( ^{3} $ 4% Senior Notes and $19.8 million of the 9 \( ^{1} $ 2% Senior Notes in 2016 in exchange in the aggregate for the issuance of 2,748,403 shares of common stock and $3.5 million in cash. A gain on extinguishment of debt of $89.6 million was recognized on the retirement of the senior notes during 2016 for the difference between the market value of the stock and the net carrying value of the debt. During 2015, the Company acquired $23.9 million in principal amount of the 7 \( ^{3} $ 4% Senior Notes and $105.6 million in principal amount of the 9 \( ^{1} $ 2% Senior Notes for an aggregate purchase price of $42.7 million. The gain of $82.4 million recognized on the purchase of the senior notes and the loss resulting from the write-off of deferred loan costs associated with the Company’s prior bank credit facility of $3.7 million are included in the net gain on extinguishment of debt in 2015.

Comstock has a $50.0 million revolving credit facility with Bank of Montreal and Bank of America, N.A. that matures on March 4, 2019. As of December 31, 2017, there were no borrowings outstanding under the revolving credit facility. Indebtedness under the revolving credit facility is guaranteed by all of the Company’s subsidiaries and is secured by substantially all of Comstock’s and its subsidiaries’ assets. Borrowings under the revolving credit facility bear interest, at Comstock’s option, at either (1) LIBOR plus 2.5% 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 1.5%. A commitment fee of 0.5% per annum is payable quarterly on the unused credit line. The revolving credit facility contains covenants that, among other things, restrict the payment of cash dividends and repurchases of common stock, limit the amount of additional debt that Comstock may incur and limit the Company’s ability to make certain loans, investments and divestitures. The only financial covenants are the maintenance of a ratio of current assets, including availability under the revolving credit facility, to current liabilities of at least 0.9 to 1.0 which increases to 1.0 to 1.0 on March 31, 2018 and the maintenance of an asset coverage ratio of proved developed oil and natural gas reserves to the amount outstanding under the revolving credit facility of at least 2.5 to 1.0. The Company was in compliance with these covenants as of December 31, 2017.

All of the Company’s subsidiaries guarantee the bank credit facility, the 10% Senior Secured Toggle Notes, the 7 \( ^{3} $ 4% Convertible Second Lien PIK Notes, the 9 \( ^{1} $ 2% Convertible Second Lien PIK Notes, and the other outstanding senior notes. The bank credit facility, the 10% Senior Secured Toggle Notes and the convertible notes are secured by liens on substantially all of the Company’s and its subsidiaries’ assets. The allocation of proceeds related to the liens on our assets are governed by intercreditor agreements granting priority to the bank credit facility. Proceeds from liens on the convertible notes are also subject to the priority of the 10% Senior Secured Toggle Notes. The liens that previously secured the 10% Senior Secured Notes that were not tendered for exchange were released and these notes are no longer secured.

## (7) Stock-based Compensation

The Company grants restricted shares of common stock and performance share units to key employees and directors as part of their compensation under the 2009 Long-term Incentive Plan. Future awards of performance share units, restricted stock grants or other equity awards are available under the stockholder approved 2009 Long-term Incentive Plan for 1,983,864 shares of common stock.

During 2015, 2016 and 2017, the Company had $8.1 million, $4.7 million and $5.9 million, respectively, in stock-based compensation expense which is included in general and administrative expenses.

## Restricted Stock

The fair value of restricted stock grants is amortized over the vesting period, generally one to three years, using the straight-line method. Total compensation expense recognized for restricted stock grants was $6.0 million, $3.4 million and $3.9 million for the years ended December 31, 2015, 2016 and 2017, respectively. The fair value of each restricted share on the date of grant is equal to the market price of a share of the Company’s stock.

A summary of restricted stock activity for the year ended December 31, 2017 is presented below:

<table><tr><td></td><td>Number of Restricted Shares</td><td>Weighted Average Grant Price</td></tr><tr><td>Outstanding at January 1, 2017</td><td>354,986</td><td>$15.60</td></tr><tr><td>Granted</td><td>500,002</td><td>$11.11</td></tr><tr><td>Vested</td><td>(185,652)</td><td>$18.88</td></tr><tr><td>Forfeitures</td><td>(49,469)</td><td>$13.10</td></tr><tr><td>Outstanding at December 31, 2017</td><td>619,867</td><td>$11.14</td></tr></table>

The per share weighted average fair value of restricted stock grants in 2015, 2016 and 2017 was $26.70, $5.46 and $11.11, respectively. Total unrecognized compensation cost related to unvested restricted stock of $3.8 million as of December 31, 2017 is expected to be recognized over a period of 1.8 years. The fair value of restricted stock which vested in 2015, 2016 and 2017 was $3.7 million, $1.3 million and $1.7 million, respectively.

## Performance Share Units

The Company issues PSUs as part of its long-term equity incentive compensation. PSU awards can result in the issuance of common stock to the holder if certain performance criteria is met during a performance period. The performance periods consist of one year, two years and three years, respectively. The performance criteria for the PSUs are based on the Company’s annualized total stockholder return (“TSR”) for the performance period as compared with the TSR of certain peer companies for the performance period. The costs associated with PSUs are recognized as general and administrative expense over the performance periods of the awards.

The fair value of PSUs was measured at the grant date using the Geometric Brownian Motion Model (“GBM Model”) an equation that can create a series of outcomes over time. The GBM model allows the



## COMSTOCK RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Company to create multiple prospective total return pathways, statistically analyze these simulations, and ultimately make inferences to the most likely path the total return will take. Significant assumptions used in this simulation include the Company’s expected volatility and a risk-free interest rate based on U.S. Treasury yield curve rates with maturities consistent with the vesting periods, as well as the volatilities for each of the Company’s peers. Assumptions regarding volatility included the historical volatility of each company’s stock and the implied volatilities of publicly traded stock options.

Significant assumptions use to value PSUs in 2015, 2016 and 2017 included:

<table><tr><td rowspan="2"></td><td colspan="4">For the Years Ended December 31,</td></tr><tr><td>2015</td><td>2016</td><td>2017</td><td></td></tr><tr><td>Risk free interest rate</td><td>1.1%</td><td>0.9%</td><td>1.6%</td><td></td></tr><tr><td>Range of implied volatility:</td><td></td><td></td><td></td><td></td></tr><tr><td>Minimum</td><td>37%</td><td>47%</td><td>37%</td><td></td></tr><tr><td>Maximum</td><td>65%</td><td>92%</td><td>134%</td><td></td></tr></table>

In 2015, the Company granted 94,250 PSUs with a grant date fair value of $0.7 million, or $7.30 per unit. In 2016, the Company granted 60,015 PSUs with a grant date fair value of $0.4 million, or $7.00 per unit. In 2017, the Company granted 241,814 PSUs with a grant date fair value of $4.4 million, or $18.17 per unit. The fair value of PSUs is amortized over the vesting period of one to three years, using the straight-line method. Total compensation expense recognized for PSUs was $2.1 million, $1.3 million and $2.0 million for the years ended December 31, 2015, 2016 and 2017, respectively.

A summary of PSU activity for the year ended December 31, 2017 is presented below:

<table><tr><td></td><td>Number of PSUs</td><td>Weighted Average Grant Price</td></tr><tr><td>Outstanding at January 1, 2017</td><td>134,650</td><td>$22.17</td></tr><tr><td>Granted</td><td>241,814</td><td>$18.17</td></tr><tr><td>Unearned or forfeited</td><td>(94,664)</td><td>$27.01</td></tr><tr><td>Outstanding at December 31, 2017</td><td>281,800</td><td>$17.12</td></tr></table>

The final number of shares of common stock issued may vary depending upon the performance multiplier, and can result in the issuance of zero to 269,300 shares of common stock based on the achieved performance ranges from zero to two. As of December 31, 2017, there was $3.0 million of total unrecognized expense related to PSUs, which is being amortized through December 31, 2019. 85,987 PSUs were earned in 2018 and 10,857 were forfeited based on completion of a performance period.

## (8) Retirement Plan

## (9) Income Taxes

The following is an analysis of the consolidated income tax provision (benefit):

<table><tr><td rowspan="3"></td><td colspan="4">For the Years Ended December 31,</td></tr><tr><td>2015</td><td colspan="2">2016</td><td>2017</td></tr><tr><td colspan="4">(In thousands)</td></tr><tr><td>Current - Federal</td><td>$ —</td><td>$ —</td><td>$ (19,086)</td><td></td></tr><tr><td>- State</td><td>804</td><td>64</td><td>136</td><td></td></tr><tr><td>Deferred - Federal</td><td>(149,171)</td><td>—</td><td>—</td><td></td></tr><tr><td>- State</td><td>(6,078)</td><td>7,105</td><td>1,006</td><td></td></tr><tr><td></td><td>$ (154,445)</td><td>$ 7,169</td><td>$ (17,944)</td><td></td></tr></table>

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 effective tax rate and the 35% federal statutory rate for 2015 to 2017 and 21% for 2018 and future years is caused by the elimination of the corporate alternative minimum tax pursuant to the Tax Cuts and Jobs Act enacted on December 22, 2017, non-deductible stock compensation, state taxes and the establishment of a valuation allowance on deferred taxes. The impact of these items varies based upon the Company’s full year loss and the jurisdictions that are expected to generate the projected losses.

In recording deferred income tax assets, the Company considers whether it is more likely than not that its deferred income tax assets will be realized in the future. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those deferred income tax assets would be deductible. The Company believes that after considering all the available objective evidence, historical and prospective, with greater weight given to historical evidence, management is not able to determine that it is more likely than not that all of its deferred tax assets will be realized. As a result, the Company established valuation allowances for its deferred tax assets and U.S. federal and state net operating loss carryforwards that are not expected to be utilized due to the uncertainty of generating taxable income prior to the expiration of the carryforward periods.

The Company will continue to assess the valuation allowances against deferred tax assets considering all available information obtained in future periods.

The Tax Cuts and Jobs Act, which was enacted on December 22, 2017, reduced the corporate income tax rate effective January 1, 2018 from 35% to 21%. Among the other significant tax law changes that potentially affect the Company are the elimination of the corporate alternative minimum tax (“AMT”), changes that require operating losses incurred in 2018 and beyond be carried forward indefinitely with no carryback up to 80% of taxable income in a given year, and limitations on the deduction for interest expense incurred in 2018 or later of up to 70% of its taxable income for the taxable year. The Tax Cuts and Jobs Act preserved deductibility of intangible drilling costs for federal income tax purposes, which allows the Company to deduct a portion of drilling costs in the year incurred and minimizes current taxes payable in periods of taxable income. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the Tax Cuts and Jobs Act; however, it has made reasonable estimates of the effects on its existing deferred tax balances. The Company has remeasured certain deferred federal tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. The provisional amount recognized related to the remeasurement of its deferred federal tax balance was $140.4 million, which was subject to a valuation allowance at December 31, 2017. The Tax Cuts and Jobs Act also repealed the AMT for tax years beginning on or after January 1, 2018 and provides that existing AMT credit carryforwards can be utilized to offset federal taxes for any taxable year. In addition, 50% of any unused AMT credit carryforwards can be refunded during tax years 2018 through 2020. The Company accordingly reversed the valuation allowance on its AMT credit carryforward of $19.1 million that will now be refundable through 2021 and has reclassified this amount from a deferred tax asset to a non-current receivable. The Company is still analyzing certain aspects of the Tax Cuts and Jobs Act, and refining its calculations, which could potentially affect the measurement of those balances or potentially give rise to new deferred tax amounts. Comstock’s estimates may also be affected in the future as the Company gains a more thorough understanding of the Tax Cuts and Jobs Act, and how the individual states are implementing this new law.

Future use of the Company’s federal and state net operating loss carryforwards may be limited in the event that a cumulative change in the ownership of Comstock’s common stock by more than 50% occurs within a three-year period. Such a change in ownership would result in a substantial portion of Comstock’s net operating loss carryforwards being eliminated or becoming restricted, and the Company would need to recognize additional valuation allowances reflecting the restricted use of the net operating loss carryforwards in the period when such an ownership change occurred. It is highly likely that a change in ownership that would result from conversion of the Company’s convertible notes would result in limits on the future use of its net operating loss carryforwards.

The Company’s federal income tax returns for the years subsequent to December 31, 2013 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, 2012. 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 in order to manage oil and natural gas price risk. Swaps are settled monthly based on differences between the prices

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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.

All of the Company’s derivative financial instruments are used for risk management purposes and by policy none are held for trading or speculative purposes. Comstock minimizes credit risk to counterparties of its derivative financial instruments through formal credit policies, monitoring procedures, and diversification. The Company is not required to provide any credit support to its counterparties other than cross collateralization with the assets securing its bank credit facility. None of the Company’s derivative financial instruments involve payment or receipt of premiums.

The Company had the following outstanding derivative financial instruments used for oil and natural gas price risk management:

<table><tr><td>Commodity and Derivative Type</td><td>Weighted-Average Contract Price</td><td>Contract Volume (MMBtu)</td><td>Contract Period</td></tr><tr><td>December 31, 2016:</td><td></td><td></td><td></td></tr><tr><td>Natural Gas Swap Agreements</td><td>$3.37 per MMBtu</td><td>23,400,000</td><td>2017</td></tr><tr><td>December 31, 2017:</td><td></td><td></td><td></td></tr><tr><td>Natural Gas Swap Agreements</td><td>$3.38 per MMBtu</td><td>2,565,000</td><td>2018</td></tr></table>

None of the derivative contracts were designated as cash flow hedges. The Company recognizes cash settlements and changes in the fair value of its derivative financial instruments as a single component of other income (expenses). Since January 1, 2018 Comstock has added 21,600,000 MMBtu of additional natural gas swap agreements at an average contract price of $3.00 per MMBtu. These contracts begin in March and April 2018 and expire in February and March 2019.

The Company recognized a gain of $2.7 million, a loss of $5.4 million and a gain of $16.8 million from its derivative financial instruments for the years ended December 31, 2015, 2016 and 2017, respectively. Cash settlements received on derivative financial instruments were $1.2 million, $2.1 million and $9.4 million for the years ended December 31, 2015, 2016 and 2017, respectively. The estimated fair value and carrying value of the Company’s derivative financial instruments, was a current liability of $6.0 million as of December 31, 2016 and was a current asset of $1.3 million as of December 31, 2017.

The upward revisions to previous estimates in 2016 were primarily performance-related and were attributable to the Company’s well performance in the Haynesville shale as well as the expansion of the Company’s future drilling plans. The revisions in 2015 and 2017 were primarily related to changes in oil and natural gas prices.

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, 2016 and 2017:

<table><tr><td></td><td>2016</td><td>2017</td></tr><tr><td></td><td colspan="2">(In thousands)</td></tr><tr><td>Cash Flows Relating to Proved Reserves:</td><td></td><td></td></tr><tr><td>Future Cash Flows</td><td>$2,267,877</td><td>$3,588,764</td></tr><tr><td>Future Costs:</td><td></td><td></td></tr><tr><td>Production</td><td>(798,454)</td><td>(986,398)</td></tr><tr><td>Development and Abandonment</td><td>(502,848)</td><td>(672,559)</td></tr><tr><td>Future Income Taxes</td><td>(6,488)</td><td>5,239</td></tr><tr><td>Future Net Cash Flows</td><td>960,087</td><td>1,935,046</td></tr><tr><td>10% Discount Factor</td><td>(530,812)</td><td>(1,053,502)</td></tr><tr><td>Standardized Measure of Discounted Future Net Cash Flows</td><td>$ 429,275</td><td>$ 881,544</td></tr><tr><td>Standardized Measure of Discounted Future Net Cash Flows Related to Assets Held for Sale</td><td>$ 77,146</td><td>$ 109,134</td></tr></table>

The standardized measure of discounted future net cash flows at the end of 2016 and 2017 was determined based on the simple average of the first of month market prices for oil and natural gas for each year. Prices were $37.62 per barrel of oil and $2.29 per Mcf of natural gas for 2016 and $48.71 per barrel of oil and $2.88 per Mcf of natural gas for 2017. 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.
